Abstract: A catheter useful for non-surgical entry into the cervical canal of a uterus to dispense a diagnostic fluid therein. The catheter includes a tubular body having a lumen extending from a first end thereof to a second end thereof. The lumen includes a first aperture at or adjacent to the first end for dispensing a diagnostic fluid into the interior of a subject uterus, and a balloon disposed marginally adjacent to the first end of the body for fluid sealing the interior of the subject uterus. The lumen further includes a second aperture in fluid communication with the interior of the balloon for inflation thereof with the diagnostic fluid. The area of the first aperture is less than the area of the second aperture to provide a backpressure that inflates the balloon when a diagnostic fluid is injected through the catheter. In most applications, the catheter can be combined with a syringe to form a catheter apparatus.

Abstract: A catheter device for non-surgical entry into a uterus, includes a tubular body having a lumen extending from a first end thereof to a second end thereof, the lumen having an external opening adjacent to or at the first end for dispensing a diagnostic fluid into the uterus. An elongated balloon is disposed distally on the tubular body for insertion into the cervical canal of the uterus, the balloon having opposing portions which occlude opposing openings of the canal.

Abstract: An apparatus for sonographically observing a location and condition of the body. The apparatus has a pump assembly and a catheter assembly fluidly coupled to the pump assembly. The pump assembly includes a first pump for pumping a solution of sterile saline into the catheter assembly and a second pump for pumping micro-filtered air into the catheter assembly. The catheter assembly injects the solution of sterile saline and the sterile saline mixed with micro-filtered air into a location of a body. Further, a method for sonographically observing a location and condition of a body using the above apparatus.

Abstract: The invention is addressed to a medical tube holder of resilient material for the placement of endotracheal, gastrointestinal or other tubes relative to the body of a patient. The preferred embodiment includes body attachment site, a medical tube support extension projecting from the body attachment site and a frictional tube engagement structure.

Abstract: A catheter for non-surgical entry into the cervical canal or the uterus, comprising an elongated tubular catheter body. An inflatable balloon manufactured from a polyurethane material is disposed proximal to the distal end of the catheter body. The polyurethane inflatable balloon can be progressively inflated into an elliptical shape which enables the balloon to be used within the cervical canal. Additional inflation pressure inflates the polyurethane inflatable balloon to a spherical shape which enables the balloon to be used within the uterus.

Abstract: A device for the prevention of contamination of medical personnel from a patient's body secretions that may splash back during wound irrigation. The splash shield has a peripheral edge that is substantially circular. The splash shield has a flat center region which forms the middle of the splash shield encircled by an outer concave region. The outer concave region curves away from the flat center region. A peripheral edge is located at the rim of the outer concave region. The peripheral edge is flat and extends outwardly from the outer concave region in a plane substantially parallel to the flat center region. A hollow conical protrusion extends through the splash shield at a point eccentric to its center. The conical protrusion has a base that lays flush against the flat center region. As the conical protrusion extends away from the flat center region, it tapers to a top surface.

Abstract: This invention relates generally to tube apparatuses and more particularly to tube apparatuses that are connected to a source of pressurized air that forces air into the lungs of a recipient. The invention comprises an elongated flexible tube connected to a pair of nasal tubes positioned in the nares of the nose of the recipient. The ends of the elongated tube are connected to an air pressure control device. The nasal tubes include bulbous portions that seat and seal the nasal tubes in the nares. The invention also includes a yoke that adjustably connects the elongated tube to a headband on the head of the recipient. An alternate embodiment uses an endotracheal tube apparatus that is connected to the source of pressurized air for forcing pressurized air into the lungs of the recipient.

Abstract: An inhalation device for dispensing a medicament from a metered dosage cartridge that includes a hand-held housing having a mouthpiece and a passageway for ambient air, a triggering mechanism mounted in the housing, a biasing device for moving the cartridge to operative relationship with the passageway upon activation by the triggering mechanism, and a battery-powered circuit in the housing including a switch associated with the passageway and a solenoid operated mechanism secured to the housing for activating the trigger mechanism, with the switch acting to close the circuit and so activate the solenoid so as to activate the trigger mechanism and the biasing device so that the cartridge positions an activated outlet pin into the passageway. The switch is activated by the pressure of the passage of air drawn through the passageway by the inhaling action of the patient.

Abstract: A securing device for securing endotracheal tubes to a person, and for securing similar tubes extending from body cavities, is formed of a noose in a thin-walled elastomeric tubing by means of the passage of ends of the tubing through a ring of a thick-walled tubular section. Friction between the foregoing elements and between the noose and the tube secure the device to the tube. Free ends of the tubing are passed around the body of the person to be tied or secured by means of a clamp inserted into one end of the tubing.
