A proportioning device includes a proportioning machine with a temperature-compensating conductivity sensor, a controller, and pump actuator. A fluid circuit is engageable with the pump actuator, has connections for a source of water and one or more medicament concentrates, and includes a mixing container. The controller is configured to mix contents of the mixing container at a first time and to sample fluid from the mixing container, to pass the samples from the mixing container through the temperature-compensating conductivity sensor at different points in time as the fluid flows from the mixing container. The controller is further configured to mix contents of the mixing container a second time if the conductivities differ by a predefined magnitude.

Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. The control unit includes a heater/cooler device for providing heated or cooled fluid to a heat exchanger in thermal communication with the fluid heat exchange medium circulating to the heat exchange catheter, a user input device, and a processor connected to receive input from various sensors around the body and the system. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.

A method and apparatus for breathing, in which a blower is mounted in a specific part made of silicone, which reduces blower immissions and emissions. Moreover, the conducting structure influences the flow of the respiratory gas in order to reduce interference when measuring the volumetric flow.

A tube joining device includes a delivery with a first pusher member providing forward movement and backward movement along a delivery direction and delivering a wafer to a first position between a take-out position and a stand-by position, and with a second pusher member providing forward movement and backward movement along the delivery direction in combination with the first pusher member, and the wafer from the first position to the stand-by position.

Disclosed is a bioprocessing system comprising apparatus (200) including a centrifugal separation housing (210) having a temperature controllable compartment (215) for removably accepting a separation chamber (50), the apparatus further comprising at least one mixing station (250) for supporting one or more fluid storage vessels (10, 20, 30, 40), the station including a temperature controllable area (252) for increasing or decreasing the temperature of the contents of the or each supported vessel. The system further includes a disposable fluidic arrangement (100) including a centrifugal separation chamber (50) removably mountable within the compartment (215) and having one or more ports (52) allowing fluid ingress into, or egress out of the chamber, via the one or more ports in use, said ports being in fluid communication with one or more of said fluid storage vessels via fluid conduits (12, 22, 32, 42) and via one or more valve arrangement.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit having a storing part to store the liquid, the atomization unit being configured to generate an aerosol by atomizing the liquid; and a temperature control part configured to control the temperature of the liquid at a given location between the accommodating part (cartridge) and the storing part.

A method of cooling a mammal with an implantable blood pump. The method includes measuring a temperature of an internal controller, the internal controller being in communication with the implantable blood pump. an alert is generated if the temperature of the internal controller exceeds a predetermined temperature threshold.

Portable oxygen concentrator elements are described including integrated sensor/accumulator assemblies, new muffler designs, and improved airflow and internal gas connectivity. The result of the elements is an extremely compact, light reliable portable oxygen concentrator that is easy to assemble and relatively inexpensive.

Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a liquid anesthetic agent container includes a base region, an interior of the base region configured to hold liquid anesthetic agent, an adapter region, and a capillary force vaporizer (CFV) housed in the adapter region. The adapter region includes a coupling end configured to couple to a patient breathing circuit to supply anesthetic agent vaporized by the CFV to a patient.

The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.
