VP 35 Suction Unit - Service Manual

1. INTRODUCTION

GENERAL

1.1The VP35 is a high vacuum, high flow suction unit designed to conform with British and International Standards EN 60601-1:1990+A1:1993+A2:1995, ISO 10079-1:1991,

BS 5724:Part 1:1979, IEC 601-1:1977, IEC 601-1-2:1993.

1.2The suction unit can be supplied in three ways; either with a reusable jar and disposable liner system as illustrated below in Fig. 1, or with Traditional Jars (see appendix

A), or with Eschmann Suction Jars (see Appendix B), or without jars and liners but incorporating brackets to receive ‘Abbott Receptal’ style disposable items.

PUMP AND MOTOR

1.3The vacuum pump is an oil lubricated electrically driven pump/motor unit of the rotary vane type, with replaceable blades. The motor unit is designed to operate from the mains electrical supply (see serial plate for unit voltage).

1.4The pump/motor unit, its associated pipework and electrical connections are all contained within a durable, hygienic plastic case. Controls are mounted on the top of the case and comprise an illuminated* on/off power switch, a vacuum control valve and gauge.

(* On later units the switch is not illuminated.)

1.5A silencer unit in the pump exhaust line ensures that the pump operates with the minimum of noise, while the pump inlet is protected by an externally mounted sealed bacterial or combined hydrophobic/bacterial filter, both of which are disposable.

1.6All the information necessary to maintain the VP35 portable suction unit in a serviceable condition will be found in this Service Manual.

WARNING

The maintenance procedures described in this User Handbook should be made the responsibility of the engineer in charge of services in the hospital. If maintenance is neglected, suction performance could be found inadequate in an emergency situation. It is also recommended that if placed on standby for emergency duty the unit is tested by switching on, at regular intervals. Also consult the Instructions for Use for additional warnings on safe use and the disposal of potentially contaminated liquid, or solid, waste.

VP 35 Suction Unit - Service Manual

4. GENERAL CARE

CLEANING

WARNING

The equipment must be disconnected from the mains electrical supply prior to cleaning and disinfection.

4.1 The following routine should be carried out immediately after each period of use:

i.Disposable filters must be changed after each day's use, orIMMEDIATELY if wetted, or after aspiration of infective fluids.

ii.All components likely to be in contact with aspirated body fluids should be thoroughly cleaned and sterilized after use, or whenever it is suspected that infective fluids have been in contact with the unit.

iii.The outside of the suction unit should be washed with hot (55°C) detergent solution, e.g. 0.1% Teepol or equivalent, rinsed with clean water, and wiped dry.

iv.The jar inlet tube can be cleaned by removing the jar lid and flushing the tube through with water under pressure.

v.In case of undue frothing, for example, moisture could be sucked past the cutoff valve. If wetting of the filter indicates that this has happened, the cutoff valve assembly must be disinfected.

vi.Should the float cage, or rubber valve seat be damaged in any way, the complete cutoff valve assembly must be renewed.

vii.Phenol based disinfectants and solventbased liquids should not be used for cleaning receiver jars, use aqueous based liquids at all times.

STERILIZATION

CAUTION

To avoid cracking the jar by thermal shock, place it towards the rear of the autoclave shelf and open the door slowly. Do not use phenols or solvent based disinfectants to sterilise jars.

4.2 The jar lid assembly can be sterilized by all normal methods including high pressure autoclaving. The most suitable

method of sterilization for the jars is steam autoclaving, if chemical techniques are to be used only use aqueous based systems.

4.3 Jars and lids should be thoroughly cleaned before autoclaving and all traces of cleaning liquids removed by adequate rinsing in water. (Also see section ‘vii’ of section 4.1).

SUCTION UNIT DISINFECTION

4.4 The suction unit should be moved to a well-ventilated area designed and used as the disinfection area. Access to the area should be restricted to those people involved in the disinfection process. Initially the unit should be cleaned as detailed above [4.1- (iii)] and then disinfected as below:

iWash down all surfaces and crevices with a 70% solution of industrial methylated spirit and water. Allow drying by evaporation at room temperature.

iiAll infected or soiled cleaning materials should be disposed of safely and carefully, taking into account any National, Local or Hospital procedures covering the disposal of potentially contaminated waste.

DAILY CHECKS

4.5 To ensure the VP35 Suction Unit operates efficiently in an emergency, the following checks should be carried out daily:

i.Check jar cutoff valve for free movement. If valve action is faulty, rectify or renew lid assembly.

ii.Check jar for cracks or chips in rim. Renew if damaged. Renew rubber bung if hardened, split or damaged.

iv.With suction unit switched ‘on’, vacuum control valve turned up to maximum and suction line blocked off, check reading on vacuum gauge moves quickly to at least 600mm Hg (atmosphere at 760mm Hg).

Service unit if vacuum value low.

Note: Disposable filters, suction tubing, jars and disposable liners are relatively inexpensive items, and a stock of spares should always be readily available.
