Abstract: A connector assembly includes first and second mating connectors that can be joined to make a fluid connection. The connectors are constructed to discriminate improper connectors so that no fluid tight connection can be formed with improper connectors. The connector assembly can be used with a system for compression therapy to prevent deep vein thrombosis.

Abstract: A pump set for use with a pump to deliver a supply of liquid to a patient. The feeding set has a conduit for the nutrient liquid and a safety interlock device associated with the conduit. The pumping apparatus has a pumping device and a control system for controlling operation of the pump. An electromagnetic radiation source is operatively connected to the control system of the pump for emitting an electromagnetic radiation signal in a direction for striking the safety interlock device of the feeding set. The safety interlock device is adapted to affect the direction of the electromagnetic radiation. An electromagnetic radiation detector is operatively connected to the control system for receiving the electromagnetic radiation signal when the direction is affected by the safety interlock device, and providing an indication to the control system that the feeding set conduit is properly positioned in the feeding pump.

Abstract: A fill spout for a drainage device is disclosed which permits the user to supply water directly to a water seal chamber of the drainage device for establishing a water seal therein. The fill spout comprises a funnel having lateral sides for facilitating the entry of the water into the drainage device, a depending lip extending from the fill spout for preventing any run off or spillage, and a tab having an arcuate-shaped rest which permits the user to open and close the fill spout. In use, the user pulls the tab which opens the fill spout and places a water-filled bottle against the rest. The user then pours a predetermined amount of water through the funnel and directly into the water seal chamber.

Abstract: A milking device having a flexible, unitary body for securing and compressing patient tubing is disclosed comprising first and second portions which are tapered from one another and define a conduit that communicates with a channel formed on one side of the device and an opposing slot formed on the other side thereof. First and second portions further define first and second receptacles, respectively, each adapted to receive a roller disposed rotatably therein for engaging patient tubing. A pair of guides are provided at the entrance of the device in order to facilitate the axial advancement of patient tubing through the conduit of the body. Distal and proximal openings are formed at either end of the conduit to receive a portion of patient tubing inserted through the channel. The device may then be advanced longitudinally along the tubing as a user presses the two rollers together and engages the tubing while progressively evacuating the contents thereof into an appropriate collection site.

Abstract: A footstand for stabilizing or securing a body of a medical device against overturn. The body may especially be a chest drainage unit designed and configured to receive and collect fluids from a medical patient. The invention comprises a two leg component rotatable footstand which incorporates a gear driving mechanism which operates between the legs to simplify the action of pulling out the respective legs of the footstand. The gear driving mechanism allows the medical technician to activate the footstand by simply pulling out either the front or back leg to its stabilizing position, the other leg will automatically be rotated into its stabilizing position. A detent is provided which will provide a secure "click" sound so that a medical technician will know the legs have been pulled out away from the CDU a sufficient distance to provide the proper stabilization for the CDU.

Abstract: A sleeve which includes a tamper-evident indicator that is securely engagable to a catheter assembly and allows for clear visual indication of whether the connected tubes have been tampered with or the tubes have been disconnected and reconnected. The sleeve comprises a first and second cover portions having a hollow cylindrical shape including barb members attached to the interior surface of the cover portions. A tab connects the two cover portions and is severable from the catheter assembly upon pulling the tab relative to the cover portions, thereby releasing the sleeve. Other than by using the tab, a user cannot release the sleeve without an indication of tampering to the sleeve itself.

Abstract: A connection component suitable for use with an enteral fluid delivery set wherein the connection component consists of a threaded cap having a projecting spike thereon to penetrate and deform a foil diaphragm on the fluid container and further including an air passageway having a flexible member therein to allow filtered air to flow into the fluid container while preventing the flow of fluid from the fluid container through the air passageway.

Abstract: An improved underwater drainage device having a baffle system preferably incorporated into the water seal column positioned in flow communication with the patient's pleural cavity wherein the baffle chamber consists of a baffle insert having a baffle tube and a plurality of spaced downwardly directed baffles. And wherein the baffle tube of the present invention includes a tapered outer wall directed toward the first baffle and sidewalls having a plurality of side openings to allow the water seal to flow downwardly therethrough once the negative pressure from the patient's pleural cavity has dissipated.

Abstract: An attachment device for use in attaching a blood collection bag to the side of a chest drainage unit wherein the attachment device consists of an upper attachment arm removably fitting within an opening located on a removable bracket attached to the chest drainage unit and further including a pair of adhesive pads near the lower end of the side surface of the chest drainage unit and the collection bag holder.
