Abstract
An insufflating/suctioning valve having a valve body containing fluid flow controlling members which are two resilient plastic tubes, a spring-biased actuating mechanism having three positions to control flow or to shut off flow in each tube, or to shut off flow simultaneously in both tubes.
Claims7
An insufflating valve comprising:
- a) a valve body;
- b) two fluid connectors attached externally to said valve body and a catheter connector extending externally from said body;
- c) two hollow resilient plastic tubes extending through the interior of said body and interconnecting in fluid tight relationship each of said fluid connectors to said catheter connector;
- d) valve actuating means for selectively shutting off fluid flow by crimping each of said tubes and for permitting flow therethrough by discontinuing said crimping;
- e) abutment means transversely of and in contact with each of said plastic tubes;
- f) said valve actuating mechanism including two tube contact means each being adapted to be in contact with one of said tubes and such that said tubes are between said abutment means and said tube contact means and an actuating arm connected to said tube contact means, said arm extending from said valve body;
- g) movement of said actuating arm into a first position effecting movement of one of said tube contact means toward one of said abutment means to cause crimping of one of said tubes to prohibit fluid flow therethrough;
- said movement of said actuating arm also effecting movement of the other of said tube contact means away from the other of said abutment means;
- h) movement of said actuating arm into a second position effecting movement of the other of said tube contact means into contact with the other of said abutment means to cause crimping of the other of said tubes and the release of the first of said tube contacting means from crimping contact with the first of said abutment means;
- i) movement of said actuating arm into a third position effecting crimping movement of both tube contacting means against both abutment means to prevent fluid flow through both of said tubes;
- j) said third position of said actuating arm being intermediate said first and second positions;
- and
- k) said valve actuating mechanism is spring-biased toward said third position such that said actuating arm will automatically seek said third position upon release of said actuating arm.
