Abstract: A flow control valve to regulate the bleed flow rate of a pressurized vessel at one of only two available bleed flow rates. The flow control valve comprises an axial main gas flow passageway with an integral check valve that allows pressurization of the vessel, a bleed passageway for depressurization of the vessel, and a threaded bleed passageway cap that allows bleeding of the vessel at one of only two rates available, based on the counter-rotated position of the bleed cap.

Abstract: The invention comprises a visual pressure indicator for endotracheal cuffs. More particularly, the indicator of the invention comprises an indicating diaphragm which is sealingly positioned within a body by means of a cap. A hole is positioned within the cap to allow protrusion of an indicating stem of the diaphragm. The air space between the diaphragm and the body is connected in fluid communication with the cuff supply tube by means of passageways. A syringe-operable, one-way valve is positioned within the body to allow filling of the endotracheal cuff with air by means of a syringe, and to prevent leakage of the air from the cuff once it is properly filled. The indicator of the invention is fitted to the end of the cuff supply tube, and a conventional syringe is fitted to the indicator. When the endotracheal tube is in position within the patient's trachea, the syringe is operated to force air into the endotracheal cuff via the one-way valve, cuff supply tube, and cuff supply channel.

Abstract: A conductor tube for a battery operated flashlight is disclosed. The conductor tube comprises an inner non-conductive sleeve positioned within an outer conductive sleeve. The flashlight bulb-receiving end of the conductor tube includes a plurality of inwardly disposed lances which extend from the outer conductive sleeve through the inner non-conductive sleeve to electrically engage the base terminal of the light bulb. The lances may extend longitudinally with respect to the conductor tube to securely receive the base of the light bulb of the flashlight. Alternatively, the lances may extend substantially circumventially about the end of the conductor tube to threadably receive the base of the light bulb and establish electrical continuity therewith.

Abstract: A portable surgical wire inserting instrument comprising a housing defining a handle, a drive casing and a nose piece removably mounted to said drive casing. The housing holds a source of power electrically connected to a motor both of which are enclosed within the housing. A wire holding tube mounted in the housing is provided with a chuck at one end adapted to grab and fixedly hold an inner chuck of a sterile wire pack inserted in the wire holding tube. Beveled gears connect the motor to the wire holding tube and are adapted to rotate the wire holding tube upon energization of the motor. The sterile wire pack comprises a wire body having a plurality of flats and a cutting tip edge of smaller length than the diameter of the wire. The inner chuck is mounted on the wire body and the wire and chuck are covered with a material covering.

Abstract: A portable surgical wire inserting instrument comprising a housing defining a handle and a head casing. The housing handle holds a removable power pack in which is mounted a motor and a source of power electrically connected to the motor. A miter gear extends from the power pack and is connected by a drive shaft to the motor. A collet is mounted in the housing and is selectively adjusted to grip a plurality of different diameter surgical wires through the action of a knob and cam mechanism located on top of the instrument head.Rotation of the knob to one of a number of different positions establishes a number of different positions for the pivot points of thrust bars which act upon pins to draw the collet into an internally coned tube. Each position corresponds to a location of the thrust bar pivots suitable for gripping wires of different sizes.

Abstract: A portable surgical wire inserting instrument comprising a housing defining a handle, a drive casing and a nose piece removably mounted to said drive casing. The housing handle holds a removable cassette in which is mounted a motor and a source of power electrically connected to the motor. A beveled gear extends from the cassette and is connected by a drive shaft to the motor. A wire housing tube mounted in the housing is provided with a chuck at one end adapted to grab and fixedly hold an inner chuck of a wire inserted in the wire holding tube. A beveled gear in the drive casing connects the beveled gear extending from the cassette to the wire holding tube with the gears being adapted to rotate the wire holding tube upon energization of the motor.

Abstract: A variable temperature portable cautery includes a housing configured to retain a voltage source, such as a plurality of batteries, and an electrically heated cautery tip carried by the front end of the housing in operative relation with each other. A manually operable switch is provided on the housing to allow selective energization of the cautery tip from the voltage source. A rotatably adjustable variable resistor is mounted on the rear end of the housing and is connected in circuit between the voltage source and heated tip to allow the temperature of the tip to be selectively varied. The movable contact of the switch and the wiper contact of the variable resistor are provided by the respective ends of a common conductor member extending longitudinally in the housing.
