3.1 Description

WARNING: Do not use this device in the

presence of ﬂ ammable anesthetics. Static charges may not dissipate and possible explosion hazard exists in the presence of these agents.

The PTS-ISU is a dual purpose vacuum regulator which provides either intermittent or continuous suction. It can be used for NG drainage (intermittent) or pharyngeal/tracheal (continuous) suctioning throughout the hospital.

A patented safety feature Push-To-Set™ (PTS) automatically occludes the patient circuit as the desired vacuum level is selected. It prevents higher than desired vacuum levels from being accidentally delivered when patient suctioning begins. The suction control knob must ﬁ rst be pushed and then turned to set vacuum levels.

Each unit contains a dual spring regulator module to regulate and adjust suction which is precise in the critical care range (0-200 mmHg/26.7 kPa) and quickly moves to full wall vacuum for resuscitation. It requires only two turns from zero to full wall vacuum. Each unit contains a vacuum gauge, an ON/OFF switching module and adjustable timing valves.

In use, the vacuum source is connected through the regulator module which functions as an automatic valve. Rotating the suction control knob adjusts the position of the regulator module and selects a predetermined level of suction.

3/Descriptions/Speciﬁ cations

(3.1 Description Continued) During use, as the ﬂ ow requirement increases, the

valve automatically opens to maintain suction at the preset level. Conversely, when the ﬂ ow requirement decreases, the valve automatically closes to maintain suction at the preset level. The same mechanism compensates for changes in supply vacuum to automatically maintain the pre-set suction level.

4/Operation

4.1 Equipment Setup

Insert the adapter/probe into the vacuum wall outlet. If the regulator is mounted elsewhere, connect a vacuum supply hose between the regulator’s adapter/ probe and the wall outlet.

WARNING: Connection to pressure sources,

even momentarily, could injure the patient or operator and damage the equipment.

Use hospital-supplied suction tubing between the vacuum regulator and the collection container, and between the patient port of the collection container and the patient (minimum inside diameter is 6 mm[0.25 in]).

An Ohio Medical Hydrophobic Filter or Hydrophilic Filter and Overﬂ ow Safety Trap (OST) should be used between the collection container and regulator to prevent contamination of the regulator, wall outlet and pipeline system.

ISO 10079-3 (BS 7259: Part 2, section 5.1.2) states that “the usable volume of the collection container shall not be less than 500 ml.”

Locking Gland Fitting

Figure 3

1. Raise the sleeve and insert the OST into the regulator ﬁ tting.

2. Turn the trap clockwise about one and a half turns to engage the threads. The trap does not need to be screwed tight; an O-ring in the regulator ﬁ tting provides a vacuum seal. The trap should rotate freely to allow the desired nipple positioning.

3. Lower sleeve to lock trap in position.

Note: For proper installation of adapters/probe and ﬁ ttings, see section 9.

4.1.1 Attaching the Overﬂ ow Safety Trap (OST))

CAUTION: To help prevent aspirate from

entering the regulator as a result of misuse, an OST should be attached prior to its use. Aspirate in the regulator may impair its operation. The use of the OST and suction ﬁ lter will help prevent this and extend the life of suction equipment.

DISS ﬁ tting

Figure 4

1. Insert the OST into the regulator ﬁ tting. Situate the nipple in the desired position.

2. Turn the DISS wing nut clockwise to engage threads and tighten (there is no O-ring, so the vacuum seal depends on a tight connection).

4/Operation

4.2 Mode Selection

Figure 5

IOIO (INT)- suction is intermittent (cycled “on” and “off”) and the suction level can be adjusted with the suction control knob when cycled “ON”.

O (OFF)- No suction is supplied to the patient.

I (CONT) - Suction is continuous and can be adjusted with the suction control knob.

Figure 7

2. Push and rotate the suction control knob until the vacuum gauge indicates the required setting.

CAUTION: The suction control knob must be

completely depressed in order to adjust the vacuum level. Failure to do so may damage the vacuum regulator.

4.4 Pre-Use Checkout Procedure

WARNING: The Pre-Use Checkout Procedure

must be performed before using the equipment on each patient. If the regulator fails any part of the Pre-Use Checkout Procedure, it must be removed from service and repaired by qualiﬁ ed service personnel.

4.3 Setting the Suction Level

Figure 6

1. Turn the mode selector switch to I (CONT).

All tests must be performed with supply vacuum of 500 mmHg (67 kPa) minimum.

1. Turn the mode selector switch to O (OFF).

Push and rotate the suction control knob one full turn clockwise (increase). Release. The gauge needle should not move.

2. Move the mode selector switch to I (CONT). The gauge should indicate vacuum. Push and rotate the suction control knob fully counter-clockwise (decrease) until it stops and release. The gauge needle should move to zero and remain there.

3. Push the suction control knob and set the following:

REGULATOR (Type) SETTING PTS-ISU Increase the suction to

90 mmHg (12 kPa)

4. Slowly release and push the suction control knob to create various ﬂ ow rates through the regulator. Check that the suction level is maintained when the knob is fully pushed in.
