Syringe positioning apparatus and methods are disclosed that provide for automated positioning of a syringe at an axially aligned position on a predetermined axis. The apparatus and methods employ first and second members having opposing surfaces that include first and second ramps, respectively, wherein the first ramp angles upward and away from the second member, and the second ramp angles upward and away from the first member. At least one of the first and second members may be advanceable toward the other by an actuator, wherein the first and second ramps may slidably engage a syringe and thereby elevate the syringe to the axially aligned position on the predetermined axis.

Syringe positioning apparatus and method

A syringe tip cap is provided for use with an automatic syringe loading apparatus. The cap includes a body having an exterior surface and an interior surface, and having a first end and an opposite second end. The first end is defined by at least one generally 'V'-shaped ramp on each of two sides of the exterior surface.

Tip cap for automatic syringe filling apparatus

A source fluid inlet for an automated filling device. The source fluid inlet may comprise features that limit engagement and/or disengagement of a source fluid tubing set from a port in the source fluid inlet except when the port is disposed in a predetermined load position. In turn, engagement and/or disengagement of the source fluid tubing may be selectively allowed to assist in reduction of interconnection errors of one or more source fluid sources. The source fluid inlet may selectively position a source fluid tubing set in a fill position to facilitate fluid communication with a receptacle to be filled (e.g., a syringe). The source fluid inlet further comprises one or more mechanisms for engagement and/or retention of a cap disposed on a syringe.

A blood treatment apparatus () comprising a degassing unit () receiving gas-containing fluid and supplying degassed fluid to a fluid chamber () of a blood treatment unit (). The degassing unit has a gas separator (), a degassing pump () to circulate fluid in a degassing line (), a flow restrictor () for reducing the pressure in the degassing line (), an absolute pressure sensor (), and a control unit () designed to control the speed of said degassing pump from the absolute pressure signal emitted by the pressure sensor. The apparatus comprises a dialysis machine provided with a device for preparing on-line a dialysis liquid from water and concentrates. The apparatus achieves an accurate and reliable regulation of a desired concentration of gas in the dialysis liquid.

Blood treatment apparatus

A technique for automatically priming and recirculating sterile fluid through an extracorporeal circuit of a dialysis machine having a blood pump, a dialyzer, and a blood tubing set including an arterial line for drawing blood from a patient and a venous line for returning the blood to the patient. The dialysis machine selectively opens and closes clamps on the arterial and venous lines and further operates a waste valve for selectively opening and closing a waste line leading to a waste drain. A connector attaches both the arterial and venous lines to the waste line downstream of the arterial and venous clamps and upstream of the waste valve. The dialysis machine automatically operating the blood pump, the clamps and the waste valve to flush the dialyzer and the blood tubing set with the sterile fluid and direct the used fluid down the waste drain. The dialysis machine then operating the blood pump and the clamps to again fill the dialyzer and the blood tubing set with additional sterile fluid and recirculate the sterile fluid through the extracorporeal circuit without the assistance of a dialysis machine operator. The dialysis machine further providing the operator with an indication when the recirculation process is complete. The connector being either one component of the disposable blood tubing set or a permanent component fixed to the dialysis machine.

An extracorporeal fluid treatment apparatus which is selectively operable in a disinfecting mode or a treatment mode includes an inlet line, a pre-treatment portion, an input pump, a heater, an input shunt, a filtration device, a post-treatment portion, a drain line and an output shunt. The apparatus also includes a combination of valves which are selectively positionable in disinfecting mode to create an input fluid circuit which includes the pre-treatment portion and the input shunt, and which is in fluid isolation from the post-treatment portion and from the filtration device. In disinfecting mode, the valves are also selectively positionable to create an output fluid circuit which includes the post-treatment portion and the output shunt, and which is in fluid isolation from the pre-treatment portion and from the filtration device. In disinfecting mode, a heated input fluid is circulated in the input fluid circuit and a heated output fluid is circulated in the output fluid circuit until disinfection of each of the input and output fluid circuits is achieved. The apparatus optionally includes a heat exchanger through which heat is transferred while in disinfecting mode from the input fluid in the pre-treatment portion to the output fluid in the post-treatment portion.

A method and apparatus for cleaning of a dialysate circuit located downstream of the dialyzer in a dialysis machine is described. The method comprises injecting a cleaning agent into the dialysis machine at a point between the dialyzer inlet port and the downstream dialysate circuit in an amount sufficient to substantially reduce the deposit in said downstream dialysate circuit; permitting flow of the agent towards the downstream dialysate circuit; and substantially preventing flow of the agent toward the dialyzer inlet port. The injection adaptor apparatus comprises an injection connector downstream of a backflow prevention valve, and two flanking tubing connectors. The apparatus is inserted at a point downstream of the dialyzer inlet port, and cleaning agent is injected into the injection connector. An adaptor to facilitate handling of cleaning agent during manual agent injection is also described. Additionally, an automated agent injection apparatus is described.

An improved dialysis apparatus and method wherein a dialysis delivery system delivers dialysate to a dialyzer through an external dialysate line with a dialyzer inlet connector and a dialysate waste system removes spent dialysate from the dialyzer through an external spent dialysate line with a dialyzer outlet connector. A bypass block comprises a first bypass block connector adapted to connect to the dialyzer inlet connector and a second bypass block connector adapted to connect to the dialyzer outlet connector and a conduit interconnecting the first bypass block connector and the second bypass block connector with a check valve located intermediate the first and second bypass block connectors and oriented to permit fluid flow only from the first bypass block connector to the second bypass block connector. An injection device is located in the conduit intermediate the check valve and the second bypass block connector connected to a cleaning agent connector adapted for connection to a container of cleaning agent by a cleaning agent line. A pump is located in the cleaning agent line intermediate the injection device and the cleaning agent connector and oriented to pump cleaning agent from the cleaning agent connector to the bypass device with a backflow prevention valve located in the cleaning agent line intermediate the pump and the injection device and oriented to permit fluid flow only from the pump to the injection device.
