Design

The RespRelief Pump is uniquely designed to prevent back-flow to the patient and leaking. It is equipped with an overflow protection mechanism which will engage, locking the trigger handle once the collection jar is filled. It is not possible to continue squeezing the handle once the collection jar is full-extremely high resistance will be felt. When this happens, the user must empty the collection jar or replace with a back-up jar for further suctioning. The overflow protection mechanism will ensure that the fluid will not enter the housing of the pump handle assembly once the collection jar is full.

When the suction port of the cap is pointed towards the floor, a flapper valve will close to avoid spilling the aspirated contents from the collection jar.

If the tip of the suction catheter becomes blocked, increased resistance will be felt and the pump handle will become difficult to operate.  Do not continue suctioning and lift the suction catheter out of the mouth.  Remove the blockage from the tip of the catheter by disconnecting and shaking until clear or replace with a fresh catheter.

If the pump is turned upside down, the overflow protection mechanism will engage, and it will be impossible to suction.

If sudden resistance is felt during suctioning and the collection jar is not full, then the overflow protection mechanism may have become engaged. To disengage the mechanism, disconnect the collection jar from the pump handle and shake the jar slightly too reset and reconnect. This should disengage the overflow protection mechanism.
