MAINTENANCE
12
Cuff transducer calibration check is complete and the calibration hose can be disconnected. The alarm will
automatically discontinue when pressure is removed from the cuff ports.
ATS LEAK TESTING
The
A.T.S.
4000TS Tourniquet is capable of maintaining the cuff pressure set-point with an internal or external leak.
Naturally it is desirable to keep plumbing leaks to an absolute minimum. For this reason, a check for signifi cant
leakage is recommended during the 6 month periodic maintenance interval as well as following any service
procedure. After verifying the functions of the
A.T.S.
4000TS Tourniquet OPERATIONS section, perform the following:
1
Access the
Service
menu as described in the
Service Menu Access
section above.
2
Touch the
Leak Test
button to access the Leak Test function interface.
3
Connect both calibration hoses that were supplied – one to the Main Cuff ports and one to the Second Cuff ports.
The end of the calibration hoses must be clamped.
4
Ensure that all external connections are leak free. If the calibration hoses are suspected of any leaks, the hoses
should be replaced before performing the leak test.
5
Press the Next button
to start the Leak test
6
The Leak test will automatically start the countdown timer once stable pressure is detected.
7
If the Leak test successfully passes, the system will issue a passing result. The numbers in the bottom left and
right indicate the total pressure loss or gain during the Leak test time period from approximately 475 mmHg
starting pressure.
8
If the Leak test is not successful, the Leak test will immediately stop at the point when the total pressure
differential exceeds the tolerated differentia. Pressure loss greater than 30 mmHg or pressure gain of greater
than 10 mmHg will cause the Leak test to fail.
9
If the system fails the Leak test, the external connections should be checked and the Leak test can be re-performed.
10
If the system continues to fail Leak test and all external connection are verifi ed to be leak-free, the system
should be removed from service immediately along with all accessories and reported to the designated individual
responsible for equipment repair within the healthcare organization. The system should be returned to Zimmer for
repair.
