Slitted pressure cuff check valve |
摘要 |
A check valve for disposable pressure infusion systems having an inflation bulb with a single open end includes a valve body with a pair of intake ports and a discharge port. Disposed at such single open end of the inflation bulb, one of the intake ports permits a flow of pressurizing air from the inflation bulb when squeezed to a pressure cuff through flexible tubing coupled to the discharge port. A flexible diaphragm having slitted openings is disposed within the check valve which provides for opening and closure of a specific port alternatively during squeezes and release of the inflation bulb.
