Abstract: A method of irrigation of a cavity of a human body by means of a medical device consisting of a container for a fluid and a filter. The container is formed with an open neck and a peripheral wall defining the receiving volume. A portion of the peripheral wall at the open neck is squeezable. The filter consists of an elongated filter element situated at an open neck of the container adjacent the squeezable portion and extending within the fluid receiving volume. The method comprises the steps of applying compressional forces to the squeezable portion of the container to urge the fluid from the fluid receiving volume into the body cavity; releasing the compressional forces to allow the squeezable portion to expand and to withdraw the fluid from the body cavity into the fluid receiving volume; and repeating the above steps.

Abstract: A motor vehicle fuel pump including a tubular steel housing and a roller vane positive displacement pump and an electric motor in the tubular steel housing. The roller vane pump includes a pair of flat side plates, a rotor between the side plates, and a T-shaped sleeve bearing in a plain bore in one of the side plates. A lip at one end of a tubular body of the sleeve bearing has a side defining an annular seat in a plane perpendicular to the tubular body. The tubular body has a shaft bore therethrough and a stepped outer wall including a large diameter part adjacent the annular seat and a small diameter part adjacent the large diameter part. The large diameter part is force fitted in the plain bore until the annular seat engages flush against a flat, outside surface of the side plate. The annular seat positions the longitudinal centerline of the tubular body perpendicular to the outer side plate for optimum alignment with the armature shaft when an end of the latter is disposed in the shaft bore.

Abstract: A manual compression aid for applying direct pressure to arterial and venous punctures to obtain hemostasis includes an integrally formed pressure applicator having a relatively flat first surface adapted for contact with a human body and having a user manipulable member for holding the pressure applicator and for applying force thereto. In one embodiment, the user manipulable member is a peg extending upwardly from the first surface. The peg not only is manipulatable by a user to manually apply pressure to a puncture site, but also functions to receive a separate cylindrical weight. The weight is pivotally mounted on the peg so that it can swivel. A stretchable bandage is used to secure and stabilize the weight in place. The bandage, being held above the puncture by the pressure applicator and the weight, also acts to supply pressure to the puncture site.

Abstract: An instrument for and method of effectively treating the prostatic urethra so as to relieve the symptoms associated with an enlarged urethra is disclosed. The tissue of at least selected portions of the prostate are compressed (preferably with a balloon inserted into the prostatic urethra so as to enhance hemostasis) and at least selected portions of the compressed tissue are directly irradiated (preferably with a laser beam transmitted from within the passageway in selected radial directions and moved along the prostatic urethra while exposing the tissue) so as to cause coagulation necrosis of selected portions of the compressed tissue so that as the tissue heals, the necrosed tissue slowly sloughs off during normal urination through the urinary tract so as to effectively remove the constricted portions of the prostatic urethra. Ultrasonic transducers are used from within the prostatic urethra to image the tissue as it is irradiated so as to monitor the procedure to insure proper exposure to the laser beam.

Abstract: A sterile surgical drape sufficiently wide to circumferentially cover and enclose a non-sterile element such as tubing and a junction between the non-sterile element and a sterile element includes a malleable strip adhered to the inside of the drape, the strip being bent around the non-sterile element that the drape covers. The malleable strip maintains the drape around the non-sterile element so that it will not contaminate a sterile field. The drape may be adhered to a sterile field by means of adhesive strips on the outside of the drape. The drape includes adhesive strips along its side to hold the drape closed about the non-sterile element. The drape may also include a pair of holes so that it may be hung from an IV pole to enclose the IV pole.

Abstract: The connection has two inserted tubes, one of which, the outer tube (6), is enlarged in order to form a casing (8) for housing two support pads (10) which are held tightly between the two tubes and a radial projection (12) of the inner tube. A gasket (14, 15) with a section in the shape of a recumbent V and which has a cylindrical flange for bearing against the inner tube and a convex flange for bearing against the outer tube, is mounted on each of the ends of the casing (8). The two gaskets face in opposite directions and are fitted onto the pads which hold them tightly. The convex flange (18) is preferably spherical only for a part of its length. This spherical part forms the surface for rubbing against the casing and enables a relative displacement of these two members with no risk of the tightness failing.

Abstract: An open-vane regenerative impeller for a fuel pump. The impeller has a ring-like body portion from which a plurality of open-vane impeller vanes extend radially out and a plurality of fan blades extend radially in. The impeller is disposed in a closed cavity between two pump bodies with the vanes in an annular pumping chamber and the fan blades in a cylindrical vapor collection chamber radially inboard of the pumping chamber. The fan blades operate to blow vapor out of the vapor collection chamber through a vapor discharge slot in one of the pump bodies when rotation of the impeller commences thereby to enhance the initial vacuum at the inlet port to the pumping chamber.

Abstract: A fuel system for maintaining fuel flow when the surface of the pool of fuel in the fuel tank is below a minimum level. The fuel pump system includes a reservoir in the fuel tank and a pump in the reservoir. A motor in the pump drives a first pump which draws fuel from a secondary chamber of the pump and discharges it to the engine. The motor also drives a second pump which draws fuel from the tank through a primary chamber and discharges it to the secondary chamber. The excess of fuel discharged by the second pump over the first pump is discharged through an orifice in the pump to the reservoir. At fuel levels below the minimum, a float controlled solenoid closes an intake port to the primary chamber causing fuel to back-flow through the flow orifice to the secondary chamber to supply the first pump.

Abstract: A medical irrigation device includes means for connecting a bulb-type syringe to a cannula such as a resectoscope so that fluid may be circulated therethrough in either direction and selectively either by a direct path therebetween or by a circuitous path including a specimen collecting receptacle whereby lavage may be accomplished with rapid reversal of fluid flow direction yet with periodic removal of particulate matter from the circulating fluid.

Abstract: An automatic tray loading apparatus for cookies or the like in which cook are divided into two rows with cookies in each row separated into groups of a given count and continuously conveyed to a loading station for loading into trays. A pair of drop chute members are aligned with the rows of cookies and each arranged to receive a discrete cookie group dropped therein by a drop gate device. The cookie group dropped into one of the drop chutes is moved laterally into close proximity to a second cookie group resting in the second drop chute to bring the cookie spacing into register with the spacing of cookie receiving compartments in the trays. Drop gate slides for each drop chute are then activated to open chute outlet openings to drop each cookie group into an appropriate compartment of a waiting cookie tray. A tray conveyor then carries away the cookie-filled tray and spots an empty tray below the drop chute outlet openings.
