The Olympus KV-5 suction pump is a medical device designed for aspiration during flexible endoscopy and general medical or surgical suction within healthcare facilities. It is not intended for thoracic drainage or domiciliary/field/transport use.
Function Description:
The KV-5 operates as a piston pump, creating a vacuum in a suction jar connected via silicone tubing and an in-line microbial filter. A suction tube connects the endoscope or other devices to the suction jar. When the unit is switched on, vacuum is generated, allowing aspiration through the connected device. The vacuum level is controlled by a regulator on the front panel, indicated by a vacuum gauge. Air is drawn through the pump and exhausted to the atmosphere at the rear of the unit. The device is available in two configurations: a single-use suction system and a reusable suction system. Single-use liners incorporate a solidifier for safe disposal and a mechanism to shut off flow if overfilled, preventing fluid from entering the pump. For reusable systems, an optional lid with an integral float mechanism is available to prevent overfilling.

- Thermal Cut-out: Contained within pump motor windings, set to operate if temperature exceeds 125°C (257°F).
- Suction Jar: 1 and 2 litre polysulfone jars, autoclavable up to 137°C max, impact resistant.
- Suction Jar Lid: Autoclavable up to 137°C max, with patient and vacuum connections.
- Suction Tubing: Silicone rubber (6.0mm ID, 12.0mm OD) for filter; PVC (7.0mm ID, 10.0mm OD) for sterile patient tubing.
- Vacuum Gauge: Range: 0 to 100 kPa, Accuracy: better than ±2.5% of full scale.
Usage Features:
- Installation: Place on a level, flat surface. Remove two M6 transit screws with fibre washers (using the provided 4mm A/F Allen key) and the associated label from the top of the unit before use. These items should be stored for re-fitting during transportation.
- Suction Jar Placement: The 1-litre suction jar slides into a bracket on the front panel. 2-litre suction jars require a workstation mounting bracket (optional, see Section 1.3 for details).
- Filter and Tubing Connection: Insert the microbial filter with "Olympus" facing outermost into the filter housing. Connect the patient tube between the suction jar lid and the endoscope/equipment. Push the open end of the filter connecting tube onto the microbial filter and fully insert the 90° connector into the suction jar lid marked "VACUUM".
- Operation: Ensure the power switch is OFF and the vacuum regulator is set to 'MIN' before connecting the power cable. Set the power switch to 'I' to start the pump. Adjust suction level by turning the vacuum regulator clockwise.
- Fluid Cut-off: The unit has a fluid cut-off mechanism. If the liner is overfilled, an integral hydrophobic filter will prevent further suction. For reusable systems, a float mechanism rises to seal the patient tube when capacity is reached.
- Overfilling Prevention: To prevent liquid backflow into the patient connecting tube, leave the unit running until the patient tube is disconnected from the suction jar.
- Safety: Do not lift the suction jar by the lid. Inspect suction jar and tubing for damage before use. Do not use anti-static tubing to connect to the endoscope. Use anti-foam agents if excessive frothing occurs.
Maintenance Features:
- Daily (by user):
- Check filter connecting tube, suction jar, and lid condition.
- Replace microbial filter and/or filter connecting tube (with 90° connector) if contaminated.
- Clean (and disinfect/sterilize if required) suction jar, lid, and filter connecting tube.
- Weekly (by user):
- Clean the unit's casework, ensuring the exhaust at the rear is clear.
- Inspect suction jar for cracks or signs of wear; replace if necessary.
- Check maximum vacuum by sealing the patient connection of the suction jar lid; it should be at least 85 kPa.
- Six-monthly (by qualified hospital engineer or Olympus agent):
- Check internal condition of unit, wiring security, etc.
- Check flow rate: should reach 60 kPa with a 2-litre suction jar connected in approximately 10 seconds.
- Cleaning and Storage:
- Remove and clean filter connecting tube with neutral detergent and water. Autoclave up to 137°C max (after removing 90° connector, which should be replaced).
- Replace microbial filter daily or when contaminated. Replace patient connecting tube when contaminated or at the end of each patient list (patient tube is not autoclavable).
- Remove lid and float assembly (if applicable) from the jar. Clean thoroughly with a soft brush and mild detergent. Suction jar cap can be sterilized by autoclaving up to 137°C max.
- Suction jar can be sterilized by autoclaving up to 137°C max or disinfected by cold fluid immersion.
- Clean KV-5 casing by wiping with a cloth dampened with detergent and water or alcohol-impregnated swab, then rinse with clean water.
- Ensure unit is thoroughly cleaned and accessories sterilized/disinfected before storage. Do not store single-use liners in damp/wet conditions.
- Transport: Ensure unit is cleaned, filter removed, transit bung fitted, transit screws with fibre washers replaced and tightened, and label 5 affixed to the top of the unit. Pack in transit packing. Failure to fit transport screws may damage the pump.
- Service: No operator-serviceable components inside. Refer servicing to qualified personnel. Olympus will not be liable for incidents resulting from unauthorized repairs. A maintenance & repair manual (part number 5070225) is available from Olympus.
- Disposal: At the end of its working life, the KV-5 should be disposed of in accordance with local regulations or policy, especially if contaminated with infectious material. It should not be disposed of as unsorted municipal waste.
