Reservoir Pressurized Or Exhausted By Squeeze Bulb Patents (Class 604/217)
  • Patent number: 4693709
    Abstract: An irrigation syringe is provided which includes a barrel having an axially extending annular groove open at the proximal end for receiving the connector portion of a resilient compressible syringe bulb in tight frictional fitting relation. The syringe barrel is adapted to receive, instead of the bulb, a plunger having a piston that may be inserted into the barrel to provide a piston-type syringe so that the barrel can be used either with a syringe bulb or a syringe plunger. The inner wall of the groove has a plurality of slots so that if the syringe barrel is employed as a funnel, liquid will flow from the groove into the barrel.

  • Patent number: 4386607
    Abstract: An enema administering apparatus insertable into the rectum for delivery of a contrast medium to internal portions of a patient's anatomy includes an enema tube joined to an enema tip wherein the enema tube and enema tip have a common contrast medium passageway extending therethrough and an air passageway which is exterior of the contrast medium passageway and is able to be coupled to a source of air for double contrast studies. The air passageway may be a passageway disposed within the enema tube and enema tip construction or may be a separate tubing member joined therewith in a suitable arrangement to introduce air for the double contrast studies once the barium has been evacuated from the patient. Air introduction means and contrast medium introduction means are provided by various arrangements suitable for use with the main enema administering apparatus concept disclosed.

  • Patent number: 4378798
    Abstract: The present invention relates to single shot stocks of animal semen to be used for artificial insemination of poultry such as turkeys, hens and guinea fowl, of the kind comprising a tube presenting an opening of relatively small diameter so that the semen introduced therein can be maintained therein by capillarity alone so as to avoid the use of any bung.The object of the invention is to provide a stock of semen of the kind referred to which avoids any risk of waste of material.To this end, the invention provides a stock of the kind comprising a tube made of relatively flexible material presenting an opening for receiving the semen whose diameter is significantly greater than the thickness of the cylindrical wall, one end of the tube terminating in a brim forming by bending the end of the wall within the tube, characterized in that this brim is shaped so that its free edge comes into direct contact with main cylindrical wall of the tube.
