APT Instructions for Use The APT is a self compensating tourniquet that can be operated at pre-selected cuff pressure. The procedure is standard for all models. All switches should be in deflate mode before selecting cuff pressure. Whether using one or two cuffs the pressure can be pre-selected. Each channel is shown separately and has independent controls. Channel ‘A’ is colour code blue and channel ‘B’ is black. All models have instructions on the unit as below :Operating Procedure - APT Mark 3 1. Apply Cuff 2. Exsanguinate 3. Using ‘pre-selected pressure’ knob, select operating pressure. 4. Inflate cuff using ‘Inflate/Deflate’ switch. Cuff pressure gauge will indicate actual pressure in cuff. This should equal the pre-selected pressure. 5. To deflate cuff return switch to deflate position. Cuff pressure gauge will return to zero. Timers : On inflation the timer is activated automatically and will register time in hours and minutes. On deflation the timer is de-activated but the time will remain on display and will not zero until the Inflate/Deflate switch is in the positive mode. Important : Do not activate switches unless you have gas supply. If cuff pressure gauge shows zero then cuff is not inflated. Check cuffs for leaks, and tubing for kinks, before use.

Warnings : As with all tourniquets with pre-selection and self compensation facilities it is advised that the following points should be observed at all times. 1. All cuffs and supply tubes should be checked regularly for leaks. 2. All switches must be in deflate mode before selecting pressure. 3. Prior to inflation cuff supply tubes should be checked for kinks and should not be trapped under other equipment. 4. The tourniquet must be connected to gas supply before activation of Inflate/Deflate switch. Safety : 1. The cuff pressure gauge will show actual pressure in the cuff unit is in inflate mode.
when the
If the cuff connectors are not engaged or inadvertently become disconnected, the cuff pressure gauge will show zero. 2. Channels are colour coded down to the cuff connectors. This immediately indicates to user which channel is in services. 3. In the unlikely event of primary gas failure the cuffs will remain inflated, provided there are no leaks in the system. N.B. Although a self compensating unit - this facility is not available unless a continuous gas is connected. 4. If cuff pressure gauge does not register a pressure, this means that the cuff is not inflated. 5. Should small leaks occur during procedure in the cuff, cuff supply hose or connector this will be compensated for up to a flow of around 2.5 litres per minute. 6. The primary pressure of 4 or 7 bar is reduced by the pressure regulator to give a working pressure of 2 bar.

Routine Maintenance Checks for APT Tourniquets and Cuffs Prior to Use: 1. Check all connectors visually and replace any washers which appear worn. 2. Check all tubing visually and replace any worn or corroded parts. 3. Check all cuffs for leaks. 4. Ensure gauge accuracy remains at + or – 5% at all times (Tested against certified methods, see “Annual Service Agreement” below) 5. Procedure for testing cuffs and inflation unit for leaks i. Connect cuffs to inflation unit using both channels. ii. Wrap cuff around suitable former ( i.e. small cylinder ). iii. Connect machine to primary supply and pre-select pressure on appropriate gauges to 450 mmhg. iv. Inflate both cuffs and check cuff pressure gauge against pre-select gauge. There should be no difference greater than +/- 5% ( 22.5 mmhg ). v. Leaving the switches on inflate mode - disconnect unit from primary source. There should be no drop in pressure over a two minute period ( cuff pressure gauges ). If the pressure drops check cuffs and connectors for leaks as ( vi ). vi. Cuffs and connectors to be sudmersed in clean water and inflated for one minute, checking for stream of bubbles which would indicate a leak. If leaks occur replace offending part. If no leaks appear this would indicate a fault in the inflation unit. Contact Service Engineers or EBME Department.

Cleaning Methods The Tourniquet unit, Mobile Stand & storage tray may be cleaned using a damp cloth and compatible cleaning and disinfecting solutions approved by your establishment for stainless steel and plated/anodised metal parts. Apply cleaning solutions to the cloth, DO NOT use excessive amounts of liquid or abrasive materials. Cleaning instructions for Tourniquet Cuffs are available on a separate instruction leaflet (Ref. 92499).
