Description 15

Page 16

2.3 User qualification

MEDUMAT Transport must only be used by persons who can verify that they have the following qualifications:

• A medical qualification and training in ventilation techniques.

• Training in the use of the MEDUMAT Transport by a person authorized by WEINMANN.

Improper use may lead to serious physical injury.

2.4 Function

The unit

MEDUMAT Transport is used to treat apnea and to provide respiratory support. By means of adjustable ventilation parameters, the unit ensures uniform ventilation tailored to the patient.

Four pressure-controlled ventilation modes (SPV, CPAP + ASB, BIPAP, PCV) and four volume-controlled ventilation modes (SVV, IPPV, S-IPPV, SIMV) can be selected to provide optimum patient ventilation.

In CPAP + ASB mode, the unit enables assisted spontaneous breathing with continuous positive airway pressure and respiration-controlled oxygen inhalation. In addition, the unit permits O

The unit allows the oxygen concentration of the respiratory gas to be adjusted.

Depending on the version, the unit's large display can show up to three spirometric graphs (pressure, flow and CO

For emergency situations, rapid selection of default types of ventilation is possible.

inhalation for preoxygenating the patient.

16 Description

Page 17

Patient Hose System

The ventilation gas is supplied to the patient via the Patient Hose System, comprising the ventilation hose and all leads necessary for comprehensive ventilation and monitoring.

The Patient Hose System is designed to permit spontaneous respiraton even if the MEDUMAT Transport malfunctions.

The Patient Hose System is available in two versions:

• Reusable hose system

• Disposable hose system

Description 17

Page 18

3. Installation

As a rule, MEDUMAT Transport only has to be installed for stationary use in rescue vehicles, helicopters or aircraft. In this case, fastening sets can be supplied as accessories.

If MEDUMAT Transport is supplied complete on a portable system, the unit is ready for operation and no further installation work is required. There are separate instruction manuals for the portable systems.

Warning!

After installation, you must perform a functional check (see “8. Function check” on page 74) to ensure reliable operation.

3.1 Connecting oxygen cylinder

Warning!

• Risk of explosion! Wash your hands thoroughly before doing any work on the oxygen supply. Hydrocarbon compounds (e.g. oil, grease, cleaning alcohol, hand cream or adhesive plasters) can cause explosive reactions if they come into contact with highly compressed oxygen.

• Never use wrenches or other tools to tighten or unscrew the union nuts.

Removing the empty cylinder

1. Close the valve on the oxygen cylinder. Switch on MEDUMAT Transport at the On/Standby/Off

switch. This allows the remaining oxygen to escape and the unit is pressure-free. Only when the contents gauge on the pressure reducer indicates 0 bar, can the screwed union be undone by hand.

2. Switch MEDUMAT Transport off again.

3. Undo the screwed union at the cylinder by hand.

18 Installation

Page 19

Connecting a new cylinder

1. Briefly open the valve of the new oxygen cylinder, then shut it again. This is to blow away any particles of dust.

Caution!

• Make sure that the patient is not connected up to the MEDUMAT Transport when you are establishing the gas supply. Otherwise, the unit’s automatic self-test will lead to incorrect results.

• When doing this, hold the valve opening away from your body in such a way that any flying particles cannot injure yourself or other people!

2. Screw the pressure reducer to the cylinder valve using the knurled union nut. Tighten the union nut by hand.

3. Screw the pressure hose onto the outlet of the pressure reducer (if not already connected) using the G 3/8 union nut.

4. Screw the other end of the pressure hose to the compressed gas connection of the MEDUMAT Transport (if not already connected).

Connecting a second oxygen source

Caution!

• Risk of insufficient oxygen supply Two oxygen sources can be connected to this unit simultaneously. Make sure that only one oxygen source is open at any given time and that there is no gas reflux. Otherwise, one of the oxygen sources may empty itself unnoticed. Sufficient oxygen supply to the patient can then no longer be guaranteed when the unit is in use.

If desired or if foreseen in your establishment, you can connect a second oxygen source, e.g., an oxygen cylinder or a CGC to the O2 inlet/outlet (quick connector to the front of the unit).

Note:

If your unit is equipped with a DIN quick connector, no oxygen can be fed into the unit with the associated DIN gas probe. With this combination it is only possible to draw off oxygen.

Safety information 25

Page 26

Caution!

• When assembling the unit, and when changing cylinders, tighten all screwed unions on the oxygen cylinder and pressure reducer by hand only. Never use tools. Overtightening damages the threads and seals, resulting in leaks.

• Secure the oxygen cylinders so that they cannot fall over. If a cylinder falls on the pressure reducer or valve, these could break off, causing a violent explosion.

• Always open the cylinder valve slowly to prevent pressure hammer on the fittings.

• Do not empty oxygen cylinders completely, as this may allow moist ambient air to enter and cause corrosion.

Ventilation/Handling

• Patient and emergency ventilator must be kept under continuous observation during ventilation.

• Prolonged ventilation can lead to atrophy of the muscles (dependency of the patient on ventilation).

• Prolonged ventilation may lead to the airway drying out. Ensure adequate conditioning of the respiratory air.

• Only apply high ventilation pressures for short periods and only if medically indicated. Permanently applied high ventilation pressures can be injurious to the patient.

• Make sure that the patient valve is not covered or its function impaired, e.g. by the patient's position.

Warning!

• Risk of hyperventilation! Continuously monitor the patient's measured respiratory rate and measured minute volume in order to prevent hyperventilation.

• Risk of air trapping! Continuously monitor the airway pressure in order to prevent air trapping.

S-IPPV mode is used for volume-controlled ventilation with a variable mandatory minute volume (MV). Throughout the entire expiration phase, a trigger is active which enables the patient to initiate a new breath. The patient is thus able to increase the respiratory rate, and therefore the minute volume MV, and to adapt them to his/her requirement.

This mode is used on patients who have inadequate spontaneous respiration.

5.8 Other ventilation functions

The ventilation functions “O2 concentration“ and “100% O2“ are available for all the ventilation modes. You can call up and set these functions at any time using the fixedassignment function buttons on the right of the display.

Warning!

Risk of poisoning! Highly concentrated oxygen can have a toxic effect on the patient if administered for too long and depending on the patient's age. When ventilating with pure oxygen or an oxygen-air mixture, make sure that oxygen is only administered for an appropriate period.

Setting the O2 concentration

To save oxygen, ventilation is normally carried out with an oxygen/air mixture. The administered oxygen concentration can be selected between 40% and 100%. The currently measured value is shown in the top info field on the display.

If you switch from oxygen/air mixture (40% O minute volume changes within the preset tolerances (see 12. “Technical Data”on page 95), at the most. To set the O

5.9 Performing ventilation

Tube

As a rule, the patient is intubated before the tube is connected to the patient valve.

1. Set the desired ventilation mode and the associated ventilation parameters.

2. Attach the patient valve to the connector of the endotracheal tube.

3. During ventilation, check the respiratory parameters on the display. This will enable you to determine whether ventilation is adequate.

Note

If your unit is equipped with the optional CO position on the basis of the capnogram and correct it if necessary.

Ventilation mask

1. If necessary, use the elbow supplied with the hose sytem to ensure optimum routing of the hose system, depending on the patient's position.

Caution

Using the elbow increases the dead space of the hose system. Take this into account when setting the ventilation parameters. Otherwise the success of treatment may be compromised.

2. Attach the mask to the hose system.

3. If necessary, introduce a Guedel oropharyngeal tube to keep the patient’s airways free.

4. Place the ventilation mask over the patient's mouth and nose.

5. Extend the patient's head and, at the same time, hold the mask tight against the patient's face by means of the EC grip.

5.10 Monitoring ventilation

General

During ventilation, you must monitor the patient continuously. You can follow the progress of ventilation on the display. You can select various display formats.

High airway resistances, e.g., due to obstructions of the airway or during external cardiac massage, may change the respiratory minute volume, depending on the ventilation mode.

If lung compliance decreases, the unit responds as follows:

• With volume-controlled ventilation, the ventilation pressure rises until the set pressure limit is reached, while the ventilation volume remains constant. Then the applied volume drops.

• With pressure-contolled ventilation, the applied volume drops while the pressure remains constant.

Example of ventilation progression before and after decrease in compliance during volume-controlled ventilation

5.11 Alarm signals

Alarm priority

MEDUMAT Transport classifies alarms in the following priority levels:

• high priority

• medium priority

• low priority

If two or more alarms occur simultaneously, alarms with the currently highest priority are displayed cyclically.

You can set limit values for alarms relating to respiratory physiology (see 6.2 “Setting alarm limits”on page 61).

Display of alarms

MEDUMAT Transport displays alarms as follows:

• High priority

– LED flashes red – Audible alarm “high priority“ every 8 seconds – Alarm text appears in info field; info field flashes

turquoise background

Operation 51

Page 52

Muting the alarm

When an alarm occurs, you can mute the audible alarm temporarily (120 seconds) by pressing the Alarm Mute button. For these 120 seconds, a yellow LED is alight. Press the button again to reactivate the acoustic alarm. The visual alarm remains active.

As soon as a higher-priority alarm occurs, the acoustic alarm is immediately reactivated.

Visual and acoustic alarms are automatically reset as soon as the cause of the alarm has been rectified.

5.12 Ventilation with filters (not supplied with the unit)

For hygiene purposes, and to condition the air for breathing, you can equip the patient valve with commercially available filters (HME, bacterial or combined HME/bacterial filters) with standard 15/22 mm connections. This increases both the inspiration and expiration resistance, so you should monitor the ventilation pressure and volume with special care.

Allowance must be made for the larger dead space, especially with children.

Always follow the filter manufacturer's operating instructions.

5.13 Ending ventilation

Caution!

Never empty the oxygen cylinder completely. Always ensure that there is a certain residual pressure in the cylinder when you return it for filling, as this prevents moist ambient air from entering and causing corrosion.

1. Check the remaining oxygen content on the contents gauge. If the contents gauge indicates 50 bar or less, the cylinder must be refilled or a reserve cylinder obtained to ensure that the unit remains ready for use.

2. Close the valve on the oxygen cylinder.

52 Operation

Page 53

3. Hold down the On/Standby/Off button for 2 seconds to switch the unit to standby.

Note:

The unit still uses up electricity in standby mode. If the unit does not need to be used for a long time or is not connected to the power supply, we recommend switching it off. To do so, hold down the On/Standby/Off until the LED alarm goes out (approx. 10 seconds ).

5.14 Calculating the oxygen level/operating time

Caution!

When calculating the oxygen level in the cylinder, take into account the unit's O

consumption (see 12.4 “O2 consumption of the unit”on page 100). Otherwise

you may miscalculate how long the cylinder will last, which may impair the success of treatment.

Oxygen level in the cylinder

Oxygen volume = cylinder volume x cylinder pressure.

Cylinder volume x Cylinder pressure = Oxygen content

Example 2

10 l x 200 bar = 2000 l

10 l x 100 bar = 1000 l

In exceptional situations, when there is no oxygen supply, the MEDUMAT Transport can also be operated with sterile compressed air.

Note

During ventilation with sterile compressed air or concentrator oxygen, the unit gives the “

↓“ alarm continuously.

5.16 Changing battery during use

The battery should be changed in good time when it starts to run low. Always keep a fully charged battey ready for changeover.

Note

If you change the battery within the space of 30 seconds, the unit restarts automatically. Settings made before changing battery are then retained.

Proceed as follows:

1. Have the fully charged battery ready to hand.

2. Pull the low battery out of the unit's battery compartment.

3. Insert the replacement battery into the compartment within 30 seconds.

4. Continue with ventilation.

Operation 55

Page 56

5.17 Battery management

MEDUMAT Transport has an internal power supply with a rechargeable battery.

Two battery versions are available:

• Battery pack Plus WM 28385 for internal and external charging; can be recharged either in the unit or using an external charger WM 28390; charge level can be checked on the battery.

• Battery pack WM 28384 for internal charging; can only be recharged in the unit; charge level can be checked on the battery.

For recharging, an external DC power supply with 12 – 15 V (internal charging) or 15V (external charging) is required. Only use the vehicle/aircraft electrical power supply. If charging in an AC wall outlet, use the charger WM 28390.

MEDUMAT Transport can be operated from an external power supply when the battery is empty. The battery is charged while the unit is in operation, but charging takes longer than when the unit is off.

Caution!

• The unit must never be operated without the battery installed because any voltage dips in the power supply cannot then be bridged, which would mean that uninterrupted ventilation of the patient is not guaranteed.

• Battery-operated medical devices have a limited operating period. MEDUMAT Transport can be operated for at least three hours without an external power supply, provided that the battery is fully charged. You should therefore ensure that the battery is always as fully charged as possible, or have a spare battery ready for use.

Battery charge level indicator (MEDUMAT Transport)

At the top left of the display you will find the symbol indicating the battery charge level. The indication is in five stages. The picture opposite shows examples of a full, half-

Ending battery charging

MEDUMAT Transport automatically determines the optimum point at which to end charging by measuring and evaluating the charging curve and battery temperature. As soon as charging has ended, the charging indicator glows steady green.

58 Operation

Page 59

Interrupting battery charging

Battery charging is continuously monitored by MEDUMAT Transport.

Problems which lead to charging being interrupted are:

• Battery temperature rises above 45°C, e.g., due to high ambient temperature, or falls below +5°C

• Charging current is too high (>3 A) e.g., short-circuit

If one of these problems occurs, charging is automatically interrupted and the charging indicator glows red.

Charging is also interrupted if there is no external power supply, e.g., because the unit, mounted on a portable system, has been removed from the wall mounting. The charging indicator does not light up in this case because this is not a fault, but a normal operating state. As soon as the external power is restored, e.g., when the portable system is replaced in the wall mounting, charging continues.

8. Function check

The user must carry out a function check on the unit before each use and after each disassembly, but at least every 6 months.

• Connect the ventilation hose, the patient valve, and a test bag to the MEDUMAT Transport.

Warning!

If this function check reveals any faults or discrepancies compared to the specified values, you must not use the MEDUMAT Transport. Have the unit repaired by WEINMANN or an authorized dealer.

You should first try to rectify the fault with the aid of the information provided in Section “9. Troubleshooting” on page 80. If this is not possible, have the unit repaired by the manufacturer, WEINMANN, or by a technician expressly authorized by WEINMANN.

A full function check comprises:

• Visual inspection for mechanical damage

• Visual inspection of the display

• “8.2 Checking the system for leaks” on page 75

• “8.3 Checking the patient valve (only reusable hose system)” on page 77

• “8.4 Automatic function check” on page 77

• We recommend you to always keep the following spare parts available:

– Spare seals for the unit connections – A replacement dust filter – PEEP control diaphragm for patient valve – Check valve diaphragm for patient valve – Measurement hose system, including water filter, for

measurement

Note

Make sure that the test bag has been serviced in accordance with the maintenance schedule.

74 Function check

Page 75

8.1 Intervals

Before each use:

• Perform a function check.

After each use or disassembly:

• Clean, disinfect and sterilize the unit (see “7. Hygienic preparation” on page 70)

• Perform a function check

At least every 6 months:

• Perform a function check.

• Check the suction filter for soiling. Unscrew and remove the filter cover. Never reinstall used filters.

8.2 Checking the system for leaks

1. Slowly open the valve on the oxygen cylinder. You can now read the cylinder pressure on the contents gauge of the pressure reducer. For example, a reading of 200 bar means that the cylinder is full, a reading of 100 bar that it is half full.

You should change the cylinder in good time, e.g. when the pressure falls below 50 bar, to ensure a sufficiently long operating time.

2. Close the cylinder valve again.

3. Observe the needle of the contents gauge on the pressure reducer for approx. 1 minute. If the position of the needle stays constant, the system is free from leaks. If the needle falls steadily, there is a leak in the system.

Function check 75

Page 76

Rectifying leaks

Note

Always keep a stock of replacement seals for the connections.

1. Prepare a soapy solution using unperfumed soap.

2. Wet all the screw and hose connections with the solution. If bubbles form, this indicates a leak.

3. Release the pressure in the system:

Close the oxygen cylinder valve. Switch MEDUMAT Transport on briefly until the contents gauge on the O off again.

Caution!

The screwed unions of the oxygen lines must only be tightened by hand.

4. If there is a leak, change the defective parts.

10. Maintenance

10.1 MEDUMAT Transport

Note:

Remember to always have a safety check carried out after maintenance and repair work.

MEDUMAT Transport must be serviced at regular intervals.

We recommend that maintenance work such as inspections and repairs should be carried out by the manufacturer, WEINMANN, or by a technician expressly authorized by WEINMANN.

Every 6 months

• Change the suction filter (see “10.4 Changing the suction filter” on page 87)

Every 2 years:

Every 2 years, you must have the cleaned and disinfected ventilator and the cleaned and disinfected reusable hose system subjected to a safety check in accordance with

§6 Medical Device Operator Ordinance (MPBetreibV) (only in the Federal Republic of

Germany) in conjunction with servicing by the manufacturer or by a technician expressly authorized by the manufacturer

• Check that the equipment is complete;

• Visual inspection: – mechanical damage – labeling of the controls – all external hoses to check for damage

• Check the batteries

• Change wearing parts: e.g., dust filter

• Check system components: portable system, oxygen fittings, hose

connections, etc.

• Check the test bag

• Final inspection according to Inspection and Test Instruction WM 28590

Maintenance 85

Page 86

Every 4 years:

• Servicing of the oxygen fittings (e.g., pressure reducer) by the manufacturer or by a technician expressly authorized by the manufacturer.

• Change wearing parts: filter screens

Every 6 years:

• Change wearing parts in the unit, button cell and wearing parts in the valve seals

Every 10 years:

• Repeat testing of the conventional steel oxygen cylinders by the TÜV (Technical Inspectorate). The next testing date is shown on the shoulder of the cylinder.

Every 12 years:

• Change the circuit boards

10.2 Batteries

The batteries used for MEDUMAT Transport are maintenance-free. Nevertheless, it is advisable to fully charge them at regular intervals (every 6-12 months, depending on the length of use) and then fully discharge them again.

This so-called “learning cycle“ calibrates the batteries' internal capacity calculation and so ensures the greatest possible accuracy of charge indication. After the learning cycle, charge the battery fully again so that it is ready for use.

Note

The batteries used for MEDUMAT Transport do not have a “memory effect“. Therefore you can recharge them when they are only partially discharged without reducing their capacity or life. But even these batteries naturally have a limited life of approx. two years or approx. 300 charging cycles.

10.3 Accessories

Separate maintenance intervals and maintenance volumes apply for the accessories to MEDUMAT Transport. Please observe the respective instructions for use.

86 Maintenance

Page 87

Oxygen cylinders must be re-examined on a regular basis. The due date can be found on the corresponding label on the cylinder.

10.4 Changing the suction filter

Caution!

Never operate the unit without the suction filter. Otherwise the unit's functions may be impaired or the unit may be damaged.

1. Undo the two screws in the filter compartment cover (hexagon socket head screws, 3 mm) and remove the cover.

Note

Support the cover on one side with a slot-head screwdriver. This prevents the cover from jamming while you are lifting it off.

Filter

Screws

cover

4. Wipe disinfect the filter compartment cover with Terralin and let it dry.

5. Install the new suction filter with tweezers so that the letters “top“ remain visible when the filter is in place.

6. Refit the cover and screw tight.

2. Remove the old filter with tweezers.

3. Clean the area of the air inlet and outlet openings with a cotton bud (moistened with Terralin).

Caution!

Do not use compressed air for cleaning the area of the air inlet and outlet openings, as this may blow dust particles into the unit. This can cause malfunctions, thereby putting the patient at risk.

Maintenance 87

Page 88

10.5 Storage

If MEDUMAT Transport is not going be used for a considerable length of time, we recommend the following procedure:

1. Clean and disinfect the unit (see “7. Hygienic preparation” on page 70).

2. Switch the unit off by pressing the On/Standby/Off button (approx. 10 seconds) until the alarm LED goes out completely.

3. Store MEDUMAT Transport in a dry place (see “12. Technical Data” on page 95).

Caution!

Be sure to observe the maintenance intervals even when the unit is in storage, as otherwise it must not be used when removed from storage.

Note

If the unit is going to be stored for longer than a month, remove the battery and store separately. To keep the battery ready for use, charge it every six months.

10.6 Disposal

Ventilator

Do not dispose of the unit in the household waste. Consult an authorized electronic waste recycling company for the proper disposal of the unit. You can find out their address from your environmental officer or from your local council.

Disposal of batteries

88 Maintenance

Do not dispose of used batteries in the household waste. Contact WEINMANN or a public waste disposal authority.
