Abstract: A hypodermic injection system particularly for use in mass immunizations having a handpiece with a grasping mechanism for holding ampules filled with injectate, a plunger for driving into the ampule to discharge the injectate in an injection process, an injection spring mechanism for driving the plunger, a motor and/or manual mechanism for cocking the injection spring mechanism, and an ampule ejection mechanism for ejecting ampules after use under control of a release mechanism. Ampules can be loaded, used and ejected without contact by the user of the system or the patient being injected. Also disclosed are a filling station for filling ampules through their injection orifices, and an arming device for setting the injection spring. Ampules are disclosed having a piston which is drivable towards an orifice to discharge injectate through the orifice. Ampules are also disclosed having enlarged proximal portions for easy grasping by the grasping mechanism of the injector.

Abstract: The invention relates to a hypodermic injection system having a direct-drive motor for moving a ram towards an injectate chamber for discharging injectate therein through a discharge orifice. The system can have an injection head attached to a housing having an injectate chamber for holding injectate to be injected, a remote discharge device with a control apparatus or the structure for holding a cartridge containing injectate. The injectate supply could be a bottle, a remote reservoir or a cartridge. An injection head can have a nose actuator for enabling an injection only if the nose actuator has engaged the body to be injected. A clamping device clamps the body to be injected. Control is effected through a microprocessor to which the electrically-operated parts of the invention are attached. Control and output signals are readable through an electronic display.

Abstract: A filling apparatus for cartridges includes a housing for holding a vial of fluid, a severing device for severing the septum of the vial, a fluid chamber for receiving the discharged fluid, a valving structure for effecting the discharge of fluid from the vial and for directing the fluid into a cartridge upon the decreasing of the size of the fluid chamber, and air inlet system for admitting air to the vial upon discharge of the fluid.

Abstract: A low cost suction regulator is disclosed in conjunction with a fluid drainage system that includes a suction chamber and a collection chamber. The suction regulator is comprised of an atmospheric chamber and a suction chamber separated by a divider. An opening in the divider has a variably biased closing member associated therewith for opening or closing the opening according to operator selected pressure differentials between the chambers. The closing member is movable along an axis that differs from the direction of airflow, thus eliminating the need for damping the forces applied to the closing member. The dividing means and its closing member will operate over the full range of angles from the vertical to horizontal axis. One embodiment of the drainage system further includes devices for measuring patient airflow, patient negativity and imposed suction.

Abstract: An ultrasonic system for measuring the volume of liquid in a container having a lid in which an ultrasonic signal is emitted and received by a sensor subsystem located on the underside of the lid of the ultrasonic system. The ultrasonic system can measure the exact amount of liquid or the level of the liquid held in the container by processing the roundtrip time the ultrasonic signals took to travel from the sensor subsystem to the surface of the liquid where the ultrasonic signals are reflected back to the ultrasonic sensor subsystem. A solid state, three-phase SCR/diode bridge converts a three-phase alternating current (AC) to a direct current (DC) power source for heating the liquid in a boiler subsystem prior to its transport to the container. A second, triac controlled heater is powered by a single phase of the three phase power source, and is used to warm and maintain the liquid held within the container at a constant temperature.

Abstract: A system for regulating flow of fluid through a flow line, such as a supply line, the line having a flow controller such as a valve, the system having a sensor for generating a signal in response to a parameter, a transmitter for transmitting a corresponding signal to a receiver at a remote location, a receiver for receiving the signal from the transmitter, an actuator for operating a regulator in response to the signal received by the actuator for operating the valve or other flow regulator.

Abstract: A jet injector system for injecting fluid into a body. The jet injection system includes capsules for holding the material to be injected, apparatus for applying force to the capsule(s) to eject the injection material(s) and a perforator for directing the jet stream for the respective materials into the body. A flyweight system is described for developing jet injection pressures, and latching devices control the flyweight system. An injector system for injecting more than one fluid is described.

Abstract: Disclosed is a waterproof, moisture-breathable, non-macerating and hypoallergenic fabric including a moisture-absorbent, non-macerating hypoallergenic substrate formed from natural or synthetic fibers, the moisture absorbency of the substrate being provided by the inherent moisture absorbency of the fiber selected and the attractive capillarity of the formed substrate. An acrylic polymer basecoat is coated onto said substrate. The basecoat has sufficient viscosity when applied to prevent strikethrough when the basecoat is applied to the substrate. A topcoat is selected from the group consisting of polyether urethane and silicone latex and is coated onto the basecoat.
