Adapters are provided for establishing fluid communication between an anesthetic agent container and an anesthetic vaporizer having a fluid port. The adapter may be mountable on the vaporizer to cooperate with the spout of an anesthetic agent container or may be mountable on an anesthetic agent container to cooperate with the fluid port of an anesthetic vaporizer to provide a sealing and/or retaining relationship therebetween.

Adapters for use with an anesthetic vaporizer

In an embodiment, a dialysis fluid cassette is disclosed. The cassette includes a plurality of walls defining at least one valve chamber, a dialysis fluid inlet, a dialysis fluid outlet and a dialysis fluid pathway. The cassette further includes a baffle extending from a first one of the walls to an opposing second one of the walls. The baffle includes an end fixed to a third one of the plurality of walls and a free end. The fixed end separates the dialysis fluid inlet from the dialysis fluid outlet and the baffle and the plurality of walls are constructed and arranged such that the flow of dialysis fluid along the pathway defined in part by the baffle slows as the flow approaches the free end of the baffle.

Dialysis systems and methods including cassette with air removal

A dialysis fluid system includes an instrument including a pump actuator and a fluid heater, and a dialysis fluid cassette. The dialysis fluid cassette includes a rigid portion defining a pumping section for operation with the pump actuator and a heating section for operation with the fluid heater. The heating section includes a dialysis fluid inlet, a dialysis fluid outlet, and a dialysis fluid heating area located between the fluid inlet and the fluid outlet, the heating section further includes an air separation chamber for collecting air separated from the dialysis fluid.

Dialysis systems and methods including cassette with fluid heating and air removal

A dialysis system includes a dialysis fluid disposable configured to hold and transport a dialysis fluid; an air separation chamber in fluid communication with the dialysis fluid disposable; and a dialysis instrument operable to pump dialysis fluid through the dialysis fluid disposable, the instrument including a vibrator configured to vibrate the air separation chamber to separate air from the dialysis fluid traveling through the chamber.

Dialysis systems and methods having vibration-aided air removal

A medical fluid delivery system includes a fluid disposable configured to hold and transport a medical fluid and an air separation chamber in fluid communication with the fluid disposable. The air separation chamber includes at least one fluid baffle floating within the air separation chamber and configured to separate air from medical fluid traveling through the chamber.

Fluid delivery systems and methods having floating baffle aided air removal

A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including a first sidewall and a second sidewall, a first fluid opening, a second fluid opening, and a separation wall extending from the first sidewall to the second sidewall, the separation wall having a free edge residing within the air separation chamber, the separation wall forcing the dialysis fluid to flow from one of the fluid openings around the free edge of the separation wall to the other of the openings.

Dialysis systems having air separation chambers with internal structures to enhance air removal

A dialysis fluid cassette includes a rigid portion defining first and second valve chambers, the rigid portion further defining an air separation chamber in fluid communication with the first and second valve chambers, the air separation chamber including a baffle and structured such that when the cassette is placed in a dialysis instrument, (i) the baffle extends upwardly from a bottom of the air separation chamber and (ii) first and second openings to the air separation chamber, communicating fluidly and respectively with the first and second valve chambers, are located near the bottom of the air separation chamber, such that the dialysis fluid is forced up one side of the baffle and down the other side of the baffle when flowing through the air separation chamber.

Dialysis systems having air traps with internal structures to enhance air removal

A medical fluid machine includes (i) a pump that pumps a medical fluid and (ii) a heater that heats the medical fluid, the heater including an electrically insulative housing, at least one flat sheet of electrically conductive material suitable for contacting the medical fluid, the sheet disposed within the insulative housing, the sheet defining a flow path for the medical fluid in which the medical fluid changes direction at least one time, a primary coil of a transformer located outside the insulative housing, the primary coil configured to induce a current into the at least one conductive sheet, creating heat that may be transferred to the medical fluid.

Dialysis system having inductive heating

Flow-through systems for processing biological fluid are disclosed. The flow-through systems include a removal device in the flow path for removing unwanted compounds and agents. The removal device includes a removal media contained within a housing made of two separate portions sealed together. The housing is maintained in a substantially vertical disposition, thereby ensuring substantially uniform and complete exposure of the fluid to the media.

Flow-through removal device and system using such device

The present invention lessens the amount of air entering between mating membranes of a pressure sensor. The pressure sensor of the present invention includes a transducer portion and separate patient or medical fluid transfer portion or dome. The transducer portion is reusable and the dome is disposable. The dome defines a fluid flow chamber that is bounded on one side by a dome membrane. Likewise, the transducer is mounted inside a housing, wherein the housing defines a surface that holds a transducer membrane. The two membranes mate when the dome is fitted onto the transducer housing. The pressure sensor enhances the seal between the mated membranes by creating higher localized contact stresses. The pressure sensor also reduces the amount of gas that permeates from the fluid chamber across the dome membrane and between the interface by making the dome membrane from a material having a low vapor transmission.

Apparatus and method for sealing pressure sensor membranes

A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.

Vacuum demand valve

A dialyzer is provided comprising a casing defining an interior and including a dialysate inlet and a dialysate outlet. A plurality of fibers are located in the interior of the casing and define a fiber bundle. A dialysate inlet fluid channel is provided in fluid communication with the dialysate inlet and includes a plurality of flutes that extend into a portion of the fiber bundles, the flutes define an opening for allowing dialysate to flow from the inlet fluid channel into the interior of the casing. Methods of providing dialysis are also provided.
