A catheter connector assembly which may be included with a corporeal drainage system, and a method of draining fluid from a bodily cavity. The catheter connector assembly may include a catheter connector and a drainage line connector. The catheter connector may include a connector body with a coupling feature, a deformable sealing element, and a retaining member. The drainage line connector may include a drainage line body first and second hinge clips, and an actuator. The actuator is designed to deform the deformable sealing element when the drainage line connector is coupled to the catheter connector.

An apparatus (10) for controlling flow of fluid from a wound site of a patient including a cavity (28) connectable to a wound site and a reservoir (16). The cavity (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The cavity (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the cavity (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the cavity (28) from the second state to the first state.

A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.

The present invention provides a nasal suction device, including a collection chamber, a resilient bulb, and a one-way valve. The collection chamber includes a main body, a cover, and an inner space, the cover being detachably connected to the main body in substantially airtight relation, to define the inner space. The resilient bulb is detachably connected to the main body in substantially airtight relation. The cover includes a first tube extending into the inner space, and the secretion passing by the first tube can be suctioned into the collection chamber. The main body includes a second tube, an opening of which adjacent to the resilient bulb is configured with the one-way valve.

A medical suction system and method of use is disclosed. The system may include a tube and a collection container. A distal portion of the tube may have a plurality of apertures that are disposed within the patient of an opening adjacent to an incision at a surgical site. A proximal portion of the tube extends out of the opening and is connected to the collection container. The opening is sealed around the tube so as to form a closed system with the collection container. The collection container may be resilient and form a vacuum by compressing by allowing the collection container to decompress. The collection container may also be provided to the user pre-compressed by rolling up the collection container and placing a band or wrapper around the compressed collection container. Alternatively, the collection container may be provided in the uncompressed state. Anchor tabs are used to secure the tube so that the plurality of apertures remain within the patient.

A nasal aspirator capable of automatically relieving pressure comprises casing, air pump component, air bag, constant pressure device and suction component; wherein, the air pump component is communicated with the air bag, and the air bag is communicated with the constant pressure device; when the air pump component works, negative pressure will be generated in the air bag; when the pressure exceeds a threshold, a pressure releasing valve will be opened to keep the air pressure inside the air bag stable; when the pressure is less than the threshold, the pressure releasing valve will be closed; and the suction component is communicated with the air bag; it further comprises a switch component, wherein the suction component defines a path for external air to enter the air bag, and the suction component is also provided with a pressure releasing channel, and the switch component can open or close the channel.

Systems, assemblies, and methods for providing negative-pressure therapy to a tissue site are described. The system can include an absorbent and a sealing layer configured to cover the absorbent. The system can also include a blister fluidly coupled to the absorbent. The blister may have a collapsed position and an expanded position. A first check valve may be fluidly coupled to the absorbent and the blister and configured to prevent fluid flow from the blister into the absorbent if the blister is moved from the expanded position to the collapsed position. A second check valve may be fluidly coupled to the blister and the ambient environment and configured to prevent fluid flow from the ambient environment into the blister if the blister is moved from the collapsed position to the expanded position.

An apparatus for negative-pressure treatment may include an enclosure having a variable volume compressible to a minimum volume, a port and an actuation surface. The apparatus may include a first one-way valve configured to allow fluid ingress to the enclosure, a second one-way valve configured to allow fluid egress from the enclosure, and an actuator configured to apply a compressive force to the actuation surface. The apparatus may further comprise a motor coupled to the actuator to apply and remove the compression force and having an operating parameter indicative of the variable volume. The apparatus may further comprise a controller coupled to the motor and configured to turn on the motor to engage the actuator to alternately apply and remove the compressive force until the enclosure is compressed to the minimum volume and turn off the motor in response to the operating parameter indicating that the chamber is compressed to the minimum volume.
