Reconditioning

When it comes to the reconditioning of Invacare® products, we always recommend using the InvaService option available from Invacare®. For further information please contact the Invacare® subsidiary in your country. Contact addresses are provided on the back of this service manual.

Before the conditioning decision is made, it should also be verified beyond a critical evaluation of objective feasibility that this is sensible from an economic and ecological perspective, taking into consideration the risk associated with the conditioning and use of the medical device and the expense and quality assurance, or whether it would be better to dispose of the medical device.
The reconditioning of the product encompasses the following points:

• 3.1 Cleaning and disinfection, page 6.
• 2.1 Periodic checks, page 5.
• 2.2 Servicing, page 5.

IMPORTANT!

• If possible, continue to use the old identification label; if this is not possible, the new identification label must contain the same information and the old serial number. (Replacement of spare parts with serial numbers).
• If screws with thread locker are loosened, these must be replaced with new ones.

Cleaning and disinfection

Manual cleaning and disinfection procedures must always be conducted in accordance with documented work instructions and with means and processes checked for effectiveness and tailored to the medical device. For mechanical cleaning and disinfection procedures, it can be procedurally ensured that the parameters necessary to attain quantifiable cleaning and disinfection performance are complied with. In order to guarantee the continuous quality of manual and/or mechanical conditioning procedures, it must be proven by at least periodical checks that the procedure is still effective and no unintentional changes have arisen.
Conditioning ends with the documented approval for use of the medical device. The chain of actions must be optimized as weaknesses in one of the necessary individual steps threaten the overall success. Transport and storage must not have a negative impact on the characteristics of the conditioned medical device. During transportation, it must be ensured that contamination of a conditioned or new medical device is precluded until its use by means of strict separation of clean/unclean devices.

All detergents and disinfectants used must be effective, compatible with one another and be gentle on the materials used. Relevant cleaning and disinfection baths must be regularly replaced at defined intervals in order to guarantee their effectiveness. With respect to contact time and concentration, the disinfectants used must comply with the list of disinfectants issued by ‘The National Institute for Clinical Excellence’ guidelines on Infection Control www.nice.org.uk/CG139 and your local infection control policy.
Detergents and disinfectants must be selected in accordance with the equipment and facilities available in each instance in order to guarantee a reliable cleaning result.

Exchanged products and product components must be disposed of in accordance with their respective material composition.

Preparation for cleaning

1. Detach the backrest from the seat plate.
2. Cover electronic connections with protective caps to ensure that water cannot get in.

Cleaning

1. Remove any superficial contamination.

2. Treat all components of the bath lifter with detergent and rinse down with clean water.

3. Replace the covers or wash them in the washing machine at a maximum temperature of 60 °C.
   IMPORTANT!Risk of damage

4. Washing at high temperatures can cause shrinkage.

5. Do not dry covers in the tumble dryer.

6. Use a universal detergent to clean the hand control, covers and charger by hand.

7. Allow all components of the bath lifter to dry in the ambient air or dry off with hand towels.

8. Check the suction cups and suction caps and replace if necessary.

Disinfection

1. Disinfect the seat surface, the front of the backrest and the hand control by wiping them down with disinfectant.
2. Dry all components of the bath lifter in the ambient air or allow them to dry in the air until there is no more superficial moisture on the product.
