      Function Test for the Weinmann MEDUMAT Standard 2

      The article below walks you through the process of performing a function test on the Weinmann MEDUMAT Standard 2 ventilator.

       

      You should perform a function test for the device and breathing circuit before each use, after each clean and after each repair.  

      Before the function test is performed please ensure the following:

      • That the device is disconnected from the patient.

      • Check there is an SD in the SD card slot.
      • Check the hygiene filter is inserted.
      • Check the oxygen supply is shut off.
      • Check battery status:
        • The rechargeable battery must be fully charged.
      • Check the following parts for external damage:
        • Device
        • Labels on the device
        • Connectors and cables
        • Breathing circuit
        • Accessories
      • Replace any damaged parts if required
      • Check the patient valve of the reusable breathing circuit. Replace the breathing circuit if necessary.

      Replace the filter if the filter wear dialogue is red. If the dialogue is yellow, and you have a spare, change the filter. Proceed without action if filter wear is green.

      If you change the filter, make sure you press “reset” to retest the filter wear. Enter the filter reset code specified in the Operator menu. On delivery, the filter reset code is “0000”.

       

      The status report will then show. Proceed with the device in accordance with the following: 

      • Device ready for use = use the device without restriction
      • Device not ready for use = Select “Details”. Check the parts listed in the display and replace them if necessary. Repeat the function check. If the function check continues to fail, contact The Ortus Group.
      • Device ready for use, but the service symbol flashes in the start menu = contact The Ortus Group for service.

      Select finish, turn off the device and disconnect the test lung from the breathing circuit.
