A filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, the passageway configured to permit passage of a fluid in a first direction defined by the inlet and the outlet; and a filter disposed within the passageway and oriented to define a volumetric direction that is different than the first direction. Another filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, and a filter disposed within the passageway, wherein the filter comprises a gelling absorbent material that, when in a dry state, is permeable to gas and that, when contacted by an aqueous fluid, converts to a gel. Such filter adaptors may be used for negative pressure wound therapy, dressing, or as syringe filters.

A reduced-pressure canister includes a canister body having a fluid reservoir, an inlet for receiving fluids from a patient, and an integral hydrophobic filter formed within a side or top portion of the canister body. The integral hydrophobic filter has a plurality of pores in the canister body that are covered by a hydrophobic coating. Other canisters, methods, and systems are also presented.

A filtration arrangement includes a filtration element and a housing disposed around, and retaining the filtration element therein. The housing includes: a first and second ends and a wall portion extending therebetween. An outlet is defined in the housing proximate the first end, a primary inlet is defined in the housing proximate the second end, and a plurality of secondary inlets are defined in the wall portion. The first end of the housing is adapted for coupling to a main housing of a flow generating device encircling an air inlet thereof. The primary and secondary inlets are positioned and structured to communicate ambient air from the surrounding environment to the filtration element. the outlet is positioned and structured to communicate the ambient air that has passed through the filtration element from one or more of the primary and secondary inlets to the air inlet of the flow generating device.

A breathing tube for a patient ventilator system providing humidified breathable gas is provided, the tube including inhalation and exhalation pathways formed in part by inhalation and exhalation tubes. A coupler member is attached at one end to the exhalation tube and forms part of the exhalation pathway, the coupler member has an integrated coupler-member electrical heating device electrically connected to the tube-portion electrical heating device. A connecting piece is detachably attachable to the other end of the coupler member and forms a part of the exhalation pathway, the connecting piece and coupler member together forming a hollow space therewithin extending from within the connecting piece to within the coupler member. A filter element is within the hollow space and extends from within the connecting piece into the coupler member, the coupler-member heating device is along the hollow space, surrounding the filter element, and adapted to heat the filter element.

A medical material is capable of suppressing adhesion of platelets and proteins even when in contact with biological components such as blood for an extended period of time. The medical material is a copolymer including hydrophobic units and hydrophilic units in which the hydrophobic units have a C2-20 terminal alkyl group in a side chain, the static contact angle of water in the copolymer is at least 30 and less than 70, and the glass transition temperature of the copolymer exists at only one point in the range from 45 C. to less than 90 C.

Manifold for a medical/surgical waste collection assembly. A shell includes a proximal end base, and a lip extending proximally from the proximal end base. The lip extends around an outlet opening defined in the proximal end base that is off-centered to a longitudinal axis of the shell. A cap including a cap head is coupled to a side wall of the shell. A drip stop may be seated within a space defined by the lip to cover the outlet opening. An arcuate section of the lip may be flush with an adjacent section of the side wall. The cap head may define a through hole, and a flapper valve unit may be coupled to the cap head with another component having ears extending through the through hole. A fence may extend from the cap head and configured to be grasped by a user.

Needleless connectors are described herein. A needleless connector includes a housing comprising a cavity and a proximal fluid port in fluid communication with the cavity. The connector further includes a filter support disposed at least partially within the cavity. The filter support can include a distal fluid port in fluid communication with the proximal fluid port. The connector further includes a filter disposed circumferentially around the filter support and between the proximal fluid port and the distal fluid port.

A manifold for a medical/surgical waste collection assembly. The manifold includes a housing shaped to be removably received within a manifold receiver of the medical/surgical waste collection assembly. An inlet fitting is coupled to the housing and adapted to be coupled with a suction line. An outlet opening is in fluid communication with the inlet fitting to define a fluid communication path from the suction line to the outlet opening and through a filter. The manifold includes a data carrier storing data useable to regulate operation of the medical/surgical waste collection assembly. The data carrier may include a radiofrequency identification tag having memory storing data suitable for determining whether the manifold is usable with the medical/surgical waste collection assembly. The RFID tag is adapted to be in electronic communication with a data reader when the manifold is coupled with the manifold receiver for communicating the data from the manifold.

An intravascular blood pump has an intake filter that reduces risk of heart tissue being sucked into an intake port of the pump. The filter defines a plurality of apertures, through which blood flows through the filter. The apertures are sized to prevent ingestion, by the input port, of the heart tissue. The filter includes a plurality of generally helical first struts wound about a longitudinal axis of the filter, and a plurality of second struts. The first and second struts collectively define the plurality of apertures therebetween. The struts may be woven filaments, or the apertures may be defined in a thin film (foil) tube, where remaining material between the apertures form the struts.

A reduced pressure treatment system includes a porous pad positioned at a tissue site and a canister having a collection chamber, an inlet, and an outlet. The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.
