Abstract: Apparatus is provided for intravenous administration of a series of solutions for cardiopulmonary resuscitation. Each solution is in a separate syringe held in place on a base plate. All syringes are connected at the same time to a single stopcock with multiple inlets and a single outlet for connection via tubing to a needle in the patient's vein. A selector handle on the stopcock is rotated to a particle inlet to select the solution in a particular syringe. The assembly eliminates the changing of syringes, the confusion and errors, and the need for assistance of the prior apparatus and speeds up the administration of the medications to make the treatment more effective, and, more importantly, reduces the risk of bacterial contamination.
Abstract: An improved flexible medullary reamer for shaping the medullary space of bones. The shaft is comprised of a single solid element. To permit the use of an elongated guide element, the shaft may be axially bored throughout its length. Attached to the shaft's opposite ends respectively, a cutting head and a means of connecting the shaft to a drive mechanism. To compliment the shaft, said cutting head and connecting means may be centrally bored.
Abstract: An apparatus for repairing torn animal body tissue in a single procedure features a suture, anchor attached at one end of the suture to prevent the suture from being pulled through the tissue, and clenching device adapted to grip the suture on the opposite side of the tissue from where the anchor device is disposed so that the torn tissue may be held together by cooperating between the anchor device and the clenching device within the body, all of which are formed of a biodegradable material so that they will all be absorbed into the body over time thereby eliminating the need for another surgical procedure to remove them from the body. The installer is used to install the clenching device with one hand so that the other is free to pull on the suture.
Abstract: A detector for determining when an occlusion has occurred in the fluid line of an IV administration set comprises means associated with an IV infusion pump to determine the resistive force exerted by fluid in the line against the pumping mechanism of the pump. The detector includes a flexible beam which is mounted between the plunger and the activator of the pumping mechanism and which bends proportionately to the magnitude of the resistive force. A strain gauge attached to the beam activates an alarm which stops the IV pump when flexure of the beam indicates an occlusion in the line has occurred.
Abstract: The external device for fixing the pins to be inserted into the bone fragments comprises at least one carrier bar, a screw for securing the pins to the carrier bar, a stirrup and a washer for securing the screw to the carrier bar. The stirrup and the washer have at least on the surfaces in contact with the rough surfaces of the bar a deformable lining. The device permits the adjustment of the different parts and improved stabilization of the pins.
Abstract: A surgical tool, for use in hip replacement operations comprises a substantially linear stem which in use seats within a preformed femur cavity. A fixed arm extends medially from an upper portion of the stem and terminates in support for a rotatable cutter. One end of the cutter is received in a seating on the stem below the fixed arm. Ancilliary equipment includes a depth locating tool, so correctly positioning the hip implant in relation to the retained femur neck.
Abstract: A unit is provided comprising a filter assembly, a cap and connector assembly to substantially reduce the risk of contaminants entering the flow of material delivered to a patient. The cap and connector assembly portion protects an administration kit from contamination during the priming of the kit. A first portion of the cap closes off the material flow route through the connector, but can be removed by tearing it away from the second portion at a weak area, opening the flow route and allowing the administration kit to be primed. As the system is primed, the second portion of the cap protects the outer surface of the connector. After the administration set has been primed, the second portion of the cap is removed, exposing the outer walls of the connector for mating with a complementary connector. The housing includes three ports for material flow.
