A breast shield unit of a breast pump for expressing human breastmilk comprises a breast shield to be placed onto a mother's breast, a breastmilk collection container for receiving expressed breastmilk, an adapter for connecting the breast shield to the breastmilk collection container and a valve head. A breastmilk channel extends from the breast shield into the breastmilk collection container through the adapter and the valve head. The valve head includes a valve which closes and opens the breastmilk channel during the pumping action, wherein a fill level sensor for measuring a fill level of the breastmilk collection container is arranged in the valve head. The breast shield unit according to the invention facilitates a fill level measurement without a structural change of the breast shield and breastmilk collection container. Moreover, it facilitates data interchange with external information storage and/or information processing units.

The disclosed invention provides a breathing circuit that includes a volume regulator that includes only three ports which include an inlet port connected to the exhalation port, a first outlet port connected to atmosphere, and a second outlet port connected to the moisturizer assembly. The breathing circuit is used for a ventilation system that delivers breaths to a patient. The inlet port of the volume regulator includes a flapper valve that moves only inward at an open position to receive the exhaled gas from the patient. The first outlet port includes a flapper valve that moves outward at an open position to exhaust gas in the volume regulator into the atmosphere. The second outlet port includes a flapper valve that moves only outward at an open position to exhaust gas in the volume regulator into the moisturizer assembly.

Described is a medical adapter assembly comprising an end including a neuraxial fitting that is not directly connectable to a standard luer fitting, an opposing end including a fitting connectable to an intravenous medical device, and a check valve that allows fluid flow from the end with the standard luer fitting to the end with the neuraxial fitting, but prevents fluid flow from the end with the neuraxial fitting to the end with the standard luer fitting. Methods of using the medical adapter assembly and kits containing the medical adapter assembly are also described.

A breast shield unit of a breast pump for expressing human breastmilk includes a breast shield (1) to be placed onto a mother's breast, a breastmilk collection container (5) for receiving expressed breastmilk, an adapter (2) for connecting the breast shield (1) to the breastmilk collection container (5) and a valve head (4). A breastmilk channel extends from the breast shield (1) into the breastmilk collection container (5) through the adapter (2) and the valve head (4). The valve head (4) includes a valve (40) which closes and opens the breastmilk channel during the pumping action, wherein a fill level sensor (6) for measuring a fill level of the breastmilk collection container (5) is arranged in the valve head (4). The breast shield unit according to the invention facilitates a fill level measurement without a structural change of the breast shield and breastmilk collection container. Moreover, it facilitates data interchange with external information storage and/or information processing units.

A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.

A treatment system for applying negative pressure therapy and fluid instillation treatment to a tissue site, particularly an abdominal tissue site, is disclosed. In some embodiments, the treatment system may include a dressing member, a plurality of fluid removal pathways, a fluid instillation matrix, a drape, a negative-pressure source, and a fluid instillation source. Instillation fluid may be delivered from the fluid instillation source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

Devices used to drain fluid are disclosed. The devices may be configured to drain fluid from a body cavity using a vacuum pressure. The devices include a reservoir and a vacuum generating member configured to expand the reservoir and generate a vacuum pressure within the reservoir. The devices can be configured to be shipped in a collapsed state.

[Problem] To provide a check-valve in which the occurrence of damage such as tearing, deformation, etc., can be suppressed. [Solution] A check-valve opens and closes an opening provided in a main body and prevents a backflow of a fluid passing through the opening; and the check-valve includes a base part 71 which is flexible, and a valve part 72 which opens and closes the opening, has a thickness thinner than a thickness of the base part 71, and is connected to the base part 71 in a state in which a periphery of the valve part 72 is surrounded with the base part 71. The valve part 72 seals the opening in a normal state of the valve part 72 being pre-urged toward the main body by an elasticity of the base part 71, and opens the opening when the fluid passes through the opening in one direction.

A medical device assembly comprises a drainage member having a proximal end, a distal end, and a body defining a lumen extending therebetween. The lumen is in fluid communication with a medical device at the proximal end. The lumen is also in fluid communication with a collection container at the distal end. The drainage member body is attached to the collection container. The body includes a valve configured to control fluid flow between the drainage member and the collection container.
