2. Introduction

2-1. General

The Dyna-Form Low Air Loss mattress is a high quality and affordable support surface suitable for medium to very high risk pressure ulcer treatment. It has been specifically designed for the prevention of pressure ulcers and offers an affordable solution to providing 24-hour pressure relief.

2-2. System Description

This product is intended to reduce the incidence of pressure ulcers while optimizing patient comfort and also to assist pain management as may be prescribed by a physician. The system is designed for use in the following care settings: f Hospital f Nursing home or individual home care setting for long-term care.

3. Setting Up/Operation

3-1. Set Up

Step 1 fPlace the mattress directly on to the bed frame taking care not to trap any inflation tubing.

The inflation tube should be towards the foot end so that it can be connected to the inflation nozzles on the pump. See figure below for reference.

Step 2f Secure the mattress straps to the bed frame (only secure straps loosely to the moving parts of the bed frame, if applicable).

Step 3 fCover with a cotton sheet to avoid direct skin contact and reduce friction.

Step 4 fHang the pump over the frame or board at the foot end of the bed.

Make sure the pump is secured.

Step 5 fConnect the inflation tubes from the mattress to the pump’s inflating nozzles.

Make sure they are properly attached.

NOTE！

Double check and make certain the air hoses are not kinked or tucked under the mattress.

Also check to ensure the CPR valve is properly attached and can be reached easily.

Step 6

fPlug the power cord into an electrical outlet with grounded/earthed AC power.

This product should be grounded/earthed.

The power cord has a grounded/earthed wire with a grounding pin.

This three-pin plug must be plugged properly into an outlet and grounded as shown in the figure in the

Grounding Instructions section.

NOTE！

Before inserting the plug into the outlet, make sure the voltage is compatible.

Step 7

fTurn on the power by pressing the power switch at the right side of the pump.

Proceed to the Operation section.

Step 8

fMake sure to disconnect the pump by unplugging the power cord when it is not in use.

3-2. Profiling the Mattress

The system may be used while the bed is in the profiled or knee-break position: fWith the bed in its present position, loosen or release the Overlay securing straps. fChange the bed to the required position (profile or knee-break). f Re-secure the securing straps.

NOTE！

Straps must be attached to moving parts of the bed frame to avoid damaging the bed mechanism and stretching the overlay.

3-3. Moving the Bed & Power Cuts

CAUTION: The patient will not receive the benefit of the system while it is disconnected and the

power unit is switched off. Therefore the system should be reconnected as soon as

possible once the bed has been moved to its new position.

If you need to move the bed with the Mattress still inflated or in the event of a major mains power failure, carry out the following procedure:

1. MATTRESS f Disconnect the quick coupler from the power unit and quickly close the lid marked “Transport”.

2. POWER UNIT f Switch off the power on the pump. Disconnect from the power plug.

The mattress & bed can now be moved

3-4. CPR Procedure

In the even of an emergency that requires the care provider to perform CPR on the patient, pull the CPR strap immediately to release the air quickly from the mattress and disconnect the air intake tube between mattress & pump. The mattress will deflate to provide a firm base for CPR.

The CPR strap is located at the top end of the mattress on the right-hand side.

3-5. Deflation , Removal & Storage

fRoll from the foot end towards the head end. The foot-end strap (if supplied) can then be stretched around the rolled mattress to prevent unrolling. fDo not fold, crease or stack the mattress and store for long periods.

3-6. Alarms & Fault Finding

Alarms

f If the pressure is lower than 8 mmHg, the low pressure alarm will be turned on. When the power is turned on, the low pressure alarm has a 40 minutes delay.

Fault Finding

SYMPTOM ACTION

Low pressure alarm fCheck connectors between the air mattress and pump. If there is any disconnection, please reconnect it. fCheck the CPR Valves. Be sure their outlets are sealed tightly. fCheck the air-connecting tubes. Be sure no single cell is leaking.

fSet the highest pressure level. Keep the tubes fully inflated and inspect for air leakage. fCheck if there is any air leakage from cells. Make sure that no leakage occurs. If any leakage occurs, please contact your equipment provider.

5. Infection Control & Cleaning

5-1. Infection Control

To prevent cross-infection, the system must be routinely cleaned between patient uses. Infection Control and routine cleaning must be carried out in accordance with your local Health Department’s Infection

Control Policy.

5-2. Cleaning

In this section, the procedures to clean and decontaminate the pump & mattress will be described. It is important to follow these procedures before applying the system to patients. The cleaning task is required at least once a week to maintain personal hygiene.

Mattress

fBrush off or wipe down all surfaces of the cover sheet with soap and water before wetting with any liquid disinfectant. fAny obvious blood spots should be wet thoroughly with an 1:9 Hypochlorite solution (1 part bleach to

9 parts water) and allow drying for at least 10 minutes. Then blot with a clean, damp cloth. fUnzip the top cover from the mattress. fBrush or wipe down all surfaces with soap and water before applying any liquid disinfectant. fCovers are immersed and soaked in disinfectant. fAfter pre-soaking, the cover is rinsed through a regular cycle in a washer with no soap then laundered with mild detergent (wash temperature 93°F, rinse temperature 78°F or on the coldest setting). fCovers are aerated until they are fully dry. (Drying temperature range 90-120°F or on the coldest setting.) fThe air cells are unsnapped from one side and are sprayed on all sides with a disinfectant. Let it sit for the required incubation time and wipe down with a clean cloth. (Be sure to disconnect all the air cells, one by one, and spray the disinfectant on all sides, including all the connecting tubes and hoses.

Let it sit for least 10 minutes.) fIf there is a base after you remove all the air cells, the base has to be sprayed down with disinfectant, inside and out. Let it sit for the required incubation time and wipe down with a cloth. fRepeat the process with the tubing set, spray, incubate, and then wipe clean. fThe carrying bag should be turned inside out and completely wiped down using the disinfectant solution. fAllow the mattress to thoroughly air dry. Once the inside is dry, turn it back: wipe down the outside of the bag with disinfectant.

fDry the mattress in a SUNLESS area after cleaning.

Pump

fDO NOT immerse or soak the pump. fCheck for external damage and move the pump to the cleaning area. fPlace the pump on a work surface and spray or wipe the outside of the case with ordinary cleaning solution. fDO NOT spray any cleaning solution directly on the surface of the pump. fDO NOT use a Hypocarbonate or Phenolic based cleaning solution as this may cause damage to the case. Allow the solution to incubate for 10 minutes or accordingly as stated by the cleaning product used. fWipe case with a clean cloth. Make sure all areas are clean (top and bottom, right & left). fSpray cloth with cleaning solution and clean faceplate. DO NOT allow excess cleaning solution on faceplate or control panel. (Damage will occur if solution gets inside the pump.) fAllow surface to thoroughly dry after cleaning. fAfter the pump is thoroughly cleaned and dried, proceed to plug in the pump and test to see if it runs normally. fUnplug the pump and store with proper identification tag.
