    摘要： A vena caval catheter is provided with a distal cage-like catheter tip having a cone connected to the inner side of the distal end of the tip within the cage and with the apex proximally of the distal end of the tip and coincident with the longitudinal axis of the catheter tip. The tip has a distal end and struts having smoothly contoured surfaces.

    摘要： An improved, four-chamber chest drainage system include (1) a collection chamber for collecting blood and other liquids to be drained from the pleural cavity of a patient, (2) an underwater seal chamber for preventing contamination of the patient's pleural cavity by atmospheric air, (3) a manometer chamber for accurately indicating the negative pressure in the patient's pleural cavity, and (4) a suction control chamber for regulating the amount of negative pressure (or suction) applied to the patient's pleural cavity. The suction control chamber has a flexible diaphragm adapted to flex in response to increased negativity above a predetermined level to block the opening to the suction source until the negativity returns to the predetermined level. A combination vent valve-and-filter assembly permits ready venting of the collection chamber to filtered atmospheric air.

    摘要： A safety device including a protective needle shield which is movable between a retracted position wherein a needle is exposed and an extended position wherein the needle is protected. The needle shield including an inwardly directed and longitudinally oriented key member thereon and an elongate barrel member includes a collar member operatively associated therewith such that the key member is movably received in a keyway on the collar member as the needle shield is moved between the retracted and extended positions. The collar member also includes a locking slot thereon to receive a portion of the key member as the needle shield is rotated about the barrel member in the extended position of the needle shield.

    摘要： A safety dental syringe of the type adapted to receive a medication cartridge therein but having a protective needle shield thereon which is movable between a retracted position wherein the needle is exposed and a locked and extended position wherein the needle is protected and the needle shield is prevented from returning to the retracted position. A collar is attached to the distal end of the dental syringe to selectively engage a key on the needle shield as the needle shield is moved between the retracted and extended positions. The needle shield slides longitudinally between the retracted and extended positions and may be rotated about the barrel of the dental syringe to lock the needle shield in the locked and extended position. A locking mechanism is disclosed which preferably includes a series of ramps and slots adapted to engage portions of the keys on the needle shield to retain the needle shield in the locked and extended position.

    摘要： An autotransfusion device for use with a chest drainage unit is disclosed which includes a collapsible blood collection bag assembly having slotted stiffener members and a holder for holding the stiffener members bowed outwardly and the bag expanded for collecting blood. The bag assembly is removable from the holder for infusing the collected blood into the patient. An inlet and a gas outlet are at the top of the bag, and a filter is arranged to filter blood from the inlet to a blood collection portion of the bag, but air from the inlet can flow to the gas outlet without flowing through the filter.

    摘要： A tube clamping device is provided which includes a pair of arms with tube clamping means thereon which are movable from an open position to a latched, closed clamping position in which the clamping means effects occlusion of a tube passing through the clamp. Each arm has a slot extending into the sidewall of the arm so that the tube can be laterally inserted and removed from the clamping device. A protective flexible sleeve provided with a slit for easy insertion onto the tube can be used to receive the clamping forces of the clamp to protect the tube.
