Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.

A fluid supply interface includes a line component having a first coupling formation for the temporary coupling of a first fluid channel, a second coupling formation for the temporary coupling of a second fluid channel, and a third coupling formation for the temporary or permanent coupling of a third fluid channel, each of said coupling formations being penetrated by a fluid line section, wherein in the line component, a fluid line assembly is formed, by means of which each fluid line section of the first, second and third coupling formations is or can be connected to each fluid line section of the other two coupling formations for the purpose of fluid transport.

A catheter system for draining a bodily fluid from a fluid source in a body of a subject. In one form, the catheter tube has a proximal end and a distal end. The catheter tube includes a drainage lumen that extends from a proximal end opening in the proximal end to a distal end opening in the distal end. The catheter system further includes a fluid sampling component in fluid communication with the distal end opening. In some embodiments, the catheter system includes a one-way check valve. In some embodiments, the catheter system includes a balloon positioned between one or more openings.

In some embodiments, a housing can define a reservoir. A lower cap can be coupled to the housing and define an outlet, and an upper cap can be coupled to the housing and can define an inlet. The upper cap can include an extending portion extending laterally a distance beyond an outermost extending portion of the lower cap relative to a central axis of the housing such that, when the lower cap and the extending portion of the upper cap contact a horizontal surface, the central axis of the housing is transverse to the surface and a sealing member is configured to sealingly engage a sealing surface of a valve seat prior to a liquid fluid level within a reservoir decreasing below a minimum threshold fluid level.

A dual chamber single-hand pump is described that includes a pump chamber with four fluid pathways. Two pathways are configured to conduct fluid to the chamber and to stop flow therethrough from the chamber, and two pathways are configured to conduct fluid from the chamber and to stop flow therethrough to the chamber. A piston positioned and moveable within the chamber separates two of the pathways from the other two pathways within the chamber. The pump can be held in a single hand by having finger grips for stabilizing the pump and a palm grip for advancing the piston. A return spring can return the piston to the original position when the palm is relaxed to allow expansion of the spring.

The invention discloses an anus cleaner, comprising a bottle body, wherein the inside of the bottle body is a hollow structure; the bottom of the bottle body is provided with a bottle bottom, and the bottle bottom is curved; the center of the bottle bottom is provided with a through hole, and a steel ball check valve is installed in the through hole; the end of the bottle body away from the bottle bottom is provided with a bottleneck, and the bottleneck is provided with threads; the bottleneck is equipped with a cleaning head; the bottom of the cleaning head is provided with threads, and the threads are provided on a mounting table; the mounting table and the bottleneck are matched and connected with the same size; the top of the mounting table is provided with a cleaning neck.

A drug delivery device includes a housing defining a shell and an inner volume, a container, a drive mechanism, a needle assembly, a fluid flow connection, and a backflow prevention mechanism. The container has an inner volume to contain a medicament to be administered to a user. The drive mechanism is at least partially disposed within the housing and exerts a force to urge the medicament out the container. The fluid flow connection is coupled to the container and the needle assembly and allows the medicament to flow from the container to the needle assembly to be administered. The backflow prevention mechanism is associated with at least one of the container, the fluid flow connection, or the needle assembly and includes at least one flow restrictor to restrict a fluid from flowing from the needle assembly to the container.

A blood pump is disclosed. The blood pump apparatus is arranged to provide pulsatile flow, and comprises a flexible inner cylindrical duct providing a blood flow region, and an outer cylindrical duct arranged to surround the inner cylindrical duct and arranged to accommodate a pumping fluid. In the pump the inner cylindrical duct is described as comprising a blood inlet for receiving blood into the region, a blood outlet for passing blood out from the blood flow region and a passageway therebetween. There is also described the feature of the inner duct comprising a non return valve at the blood inlet and a non return valve at the blood outlet, the outer cylindrical duct having a fluid port for a pumping fluid, and a pump device arranged to cyclically deliver and withdraw pumping fluid to the fluid port thereby cyclically compressing and expanding the flexible inner cylindrical duct urging blood through the blood flow region and delivering a pulsating blood flow through the blood outlet.
