Described herein is a safety system that works collectively with an automated fluid drain control apparatus and systems and clinical experts to establish protocols and methods for given patient populations to ensure that the drainage of fluid from patients is both safe and effective. It further enables the transportation of drain orders from systems external to the drain system and returns to them the drainage data on a periodic basis for inclusion into the patient chart.

A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.

An assembly for receiving a medicament container having a container carrier extending along a longitudinal axis, the container carrier having a carrier body, and a flexible carrier arm extending from the carrier body substantially parallel with the longitudinal axis; and a rotator comprising a hollow rotator body and a through hole which extends substantially parallel with the longitudinal axis, wherein the container carrier is arranged to receive the rotator such that the carrier arm extends through the through hole, and wherein the rotator is arranged to rotate about the longitudinal axis and relative to the container carrier. A cassette and a medicament delivery device are also provided.

This disclosure relates to a medical device including a hard part and a converter. The hard part has fluid paths for conducting a medical fluid through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the medical fluid is present in one of the fluid paths. At least a section of the converter is applied or superimposed to the hard part by at least one additive application method.

A device for delivering a beneficial agent is provided and generally includes a cassette, a pump, and a delivery tube. The pump includes a pump housing containing a pump assembly having a fluid drive component. The pump housing has a receiving region disposed proximate the fluid drive component and further includes a rear closure portion. The rear closure portion includes a membrane disposed between the receiving region and the fluid drive component. The cassette includes a cassette housing, which has a cassette body region defining a fluid reservoir chamber therein. The cassette further includes a cassette base region having a boundary configured to be received by the receiving region.

A system for aspirating thrombus that includes an aspiration catheter, a tubing set connected to the aspiration catheter, a pressurization element configured to couple to the tubing set and further configured to pressurize fluid from a first fluid source or allow pressurized fluid from the first fluid source to be transferred through a supply lumen of the aspiration catheter, and a sheath through which the aspiration catheter can be advanced.

A biological component cassette includes a cassette main body having a flow path for the liquid in an interior of the cassette main body. The cassette main body is flexible and has a sheet-like shape. The biological component cassette includes a frame that is less flexible than the cassette main body. The frame includes an accommodation chamber in which the cassette main body is accommodated. A side portion of the frame forms at least part of the accommodation chamber. When the cassette main body is accommodated in the accommodation chamber, one surface of the cassette main body is covered by a bottom portion of the accommodation chamber, and another surface of the cassette main body is exposed to an external environment.

An extension conduit for use with a system for aspirating thrombus includes a passageway extending between a distal end and a proximal end of the extension conduit, and a combined hydraulic and electrical control carried on the extension conduit and configured to be activated by a user to activate an electric switch while opening a valve to allow flow through the passageway.

A nitric oxide delivery system, which includes a gas bottle having nitrogen dioxide in air, converts nitrogen dioxide to nitric oxide and employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid. A nitric oxide delivery system may be used to generate therapeutic gas including nitric oxide for use in delivering the therapeutic gas to a mammal.

A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.
