摘要： An improved valving system is provided in a dialysis system in which the dialysis solution flow path through the dialyzer may be sealed off adjacent the inlet and outlet of the dialyzer, with the pumped dialysis solution being shunted so that the pump and heater do not need to be turned off. As ultrafiltration takes place over a predetermined period of time, it can be directly measured by monitoring the liquid level of a reservoir connected to the sealed portion of the dialysis solution flow path. The dialysis unit itself is held in a bracket which defines the valving system by means of a longitudinally movable and clampable retention member for bearing against the top of and holding the dialyzer member.

摘要： A method of radio frequency sealing attaches a seal member to a cylindrical, hollow, access port of a container. The method uses two sets of spaced apart die elements to generate an axial electric field along a region where the port and seal member overlap. An external peripheral ring is formed about an exterior surface of the port. The method can be used with containers having a sealed periphery as well as those previously filled with a fluid.

摘要： Described is a lancet cartridge for drawing blood samples from the finger of a patient which includes a first housing for receiving a lancet disk having a plurality of radially extending lancets, each lancet having a tooth projecting from the end thereof, and a second housing engageable with the first housing, the housings being rotatable with respect to each other, the one housing includes a ramp for receiving the end of the lancets whereby the lancet is elevated when the cartridge housing is rotated. A platform is positioned in one of the housings to receive the lancet as it is elevated by the ramp to thereby place the lancet in a cocked position. The second housing member includes at least one opening through which the end of the lancets can project to pierce the patient's finger. A trigger is positioned to be activated when a finger is placed in the opening to release the cocked lancet from the platform and pierce the patient's finger. As the housing is rotated the lancets are successively positioned on the platform so that the lancet device can be used to take multiple blood samples. If desired, the device can be disposable.

摘要： A multi-position rotary valve system is useable with a disposable fluid transfer set for carrying out a sequence of steps to implement a drain and fill procedure in connection with peritoneal dialysis. A method of carrying out peritoneal dialysis includes utilizing a rotary, multi-position, valve system in conjunction with a fluid flow transfer set having a plurality of flexible fluid flow conduits. The valve system provides for systematically opening and closing the respective fluid flow conduits in a predetermined sequence for the purpose of carrying out a drain and fill procedure of the type associated with peritoneal dialysis.

摘要： A medical device has an interior for containment of fluids; an opening into the interior, an elastomeric wall comprising a fixedly placed, flexible barrier across the opening; and a retention wall positioned adjacent to a peripheral portion of the elastomeric wall. The retention wall defines a central opening and has a generally rigid retention zone surrounding the central opening, to engage and retain a connector tube which is advanced into the central opening to open a flow aperture through the elastomeric wall, for flow through the wall and connector tube. One of the retention zone and connector tube may be made of a material of sufficient hardness that material of the other engaging member is deformed by engagement therewith, which increases the strength of retention between the retention wall and the connector tube.

摘要： A closure for a tubular access port in a medical fluid flow line or other container comprises a removable cap for enclosing and sealing the tubular access port. The cap has a closed end wall. The end wall carries an extending poker to facilitate the pushing of an antiseptic-carrying material into a lumen of the access port. The poker has an outer diameter that is less than the inner diameter of the access port. A method of using the poker is also described.

摘要： A restraining device for a tubing connector assembly can include a resilient member having a generally U-shape with forked ends that curve toward each other. Each forked end can have a recess between tines thereof. Each recess can have a blind end. The resilient member can have a bend provided with an engagement bump. The engagement bump and forked ends can be aligned such that the engagement bump coincides with a line joining the blind ends. When a cylindrical connector assembly tube is placed in the recesses, the engagement bump is urged against a side of the connector assembly to thereby prevent inadvertent disconnection.

摘要： A tubular medical fluid flow set comprises a pressure sensing chamber connected in flow-through relation to fluid flow tubing of the set. The pressure sensing chamber defines a movable, flexible, impermeable diaphragm dividing the chamber into two separate compartments. The fluid flow tubing communicates with one of the compartments and is isolated from the other of the compartments. A port is carried on the chamber, the port having a seal therein, and communicating with the other of the compartments. Thus, the other of the compartments is hermetically sealed until the port is opened for connection with a pressure measuring device, to keep the flexible diaphragm in a desired, initial position prior to opening of the seal.

摘要： Device and methods for separating a scab from a vascular access site are disclosed. The devices include providing a scab separation device having a point for initial separation of a portion of a scab from a patient's flesh, and a series of inclined surfaces leading from the point to lift and separate the scab from the access site. The scab separation device is provided with a cover so that the device is maintained as sterile. In a preferred embodiment, the scab separation device is provided as a set or assembly with a needle or needle set and, in a more preferred embodiment, the scab separation device cover is also used as a cover for a needle to maintain sterility both of an operative end of the separation device and of the needle.
