The present invention relates to a device for flushing a body cavity with a fluid, the fluid being pumped by means of two lines from the body cavity. The respective pumping capacity is regulated via controllable pinch valves, the two pinch valves being coupled in an antiparallel manner.

The present invention relates to a negative pressure generating device and an automatic negative pressure wound therapy device having a pressure changing function using the same. The present invention includes a static load elastic unit which provides an elastic force having a predetermined magnitude; a rotating unit which is connected to the static load elastic unit to rotate by the static load elastic unit; and a negative pressure cylinder which is connected to the rotating unit and interworks with the rotation of the rotating unit to generate a negative pressure therein. According to the present invention, a constant negative pressure may be consistently generated by a mechanical structure so that a manufacturing cost is significantly reduced as compared with an electrical structure and the size may be reduced.

In one general aspect, the present disclosure provides a drainage system. The drainage system may include a container having an interior and a mouth, the mouth having an outer surface and an opening. A frangible seal may cover the opening. A cap may be secured to the mouth, and the cap may be in fluid communication with a drainage line. The cap may have an inner surface for engaging with the outer surface of the mouth. The drainage system may further include a retention ring with a collar having an inner surface configured to engage an outer surface of the cap, where the retention ring includes a bead for at least partially concentrating a restriction force provided by the retention ring on an adjacent area of the outer surface of the cap.

A tissue expander having an integrated drain includes an outer shell having an opening and one or more drainage holes. An injection port is disposed in the opening of the shell and forms a fluid-tight seal with the shell. The injection port includes a needle guard having a needle guard base with a top surface, and a barrier membrane that overlies the top surface of the needle guard base. The barrier membrane defines an inflation chamber located between the top surface of the needle guard base and a bottom surface of the barrier membrane, and a drainage chamber overlying a top surface of the barrier membrane. The tissue expander includes one or more inflation ports that are in fluid communication with the inflation chamber for inflating and deflating the outer shell with a first fluid. A drainage conduit is in fluid communication with and extends between the drainage chamber and the one or more drainage holes for draining a second fluid from outside the shell.

Disclosed is a covering/lid assembly having a first compartment, a second compartment, or both. Each compartment will comprise a top side and a bottom side, the bottom side of the compartment comprising a frangible material. The first or second compartment may comprise a first material or a second material. The first or second material may comprise a flocculated red blood cell coagulant, or a red blood cell flocculent. The material within a compartment may be selectively released upon compressing a dimple and/or button located directly above the first and/or second compartment. A collection and/or biological waste management and disposal system is presented, comprising a lid/covering assembly as described and a collection container. The lid may include a perimeter having a threaded and/or snap-on assembly suitable for securely attaching the lid to a collection canister. The collection canister may comprise a red blood cell flocculent coating.

A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site, sensing a fluid parameter being applied to the tissue site, generating a fluid sensor signal in response to sensing the fluid parameter, and altering the fluid sensor signal in response to sensing that the fluid parameter changes. A fluid leak location mode may be entered. In response to the fluid leak location mode being entered, a graphical user interface that provides for fluid leak location functionality may be displayed. In one embodiment, the fluid leak location mode may be automatically entered in response to the sensor signal crossing a threshold value. Additionally, an alarm signal may be generated in response to determining that the fluid sensor signal crosses the threshold value.

An evacuated bottle system including a bottle defining a hollow interior, the bottle having a neck with a rim defining an opening; a cap assembly supported on the bottle, the cap assembly including a funnel having a first portion and a second portion, the first portion being insertable within the interior of the bottle and the second portion engaging a portion of the bottle to support the funnel above the rim, the funnel defining a bore that fluidly communicates with the hollow interior of the bottle; a self-sealing membrane that covers the bore formed by the funnel to selectively seal the hollow interior of the bottle; a cap attachable to the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane to restrain movement thereof, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle.

A computer-implemented method for quantifying fluid includes estimating a first volume of a first fluid contained in an item based on a difference between a dry weight and a wet weight of the item, and displaying a graphical representation of a container containing a volume of a second fluid and a second volume of the first fluid, wherein the graphical representation includes a first display element for receiving a first user input indicating the volume of the second fluid in the container, and a second display element for receiving a second user input indicating a total fluid volume in the container, estimating the second volume of the first fluid based on at least one of the first and second user inputs, and estimating a quantity of the first fluid based on the first and second volumes of the first fluid.

A triple-chambered container includes: a main container body with a first chamber which has an opening at its distal end; a main barrel formed and movable longitudinally within the first chamber, the main barrel defining therein a second chamber for receiving fluids, the main barrel further having an apertured stopper at its distal end; a second barrel formed within the main barrel, the second barrel defining a third chamber for receiving fluids, the second barrel being movable longitudinally within and with respect to the main barrel, the second barrel having a distal end which is engageable and disengageable with the apertured stopper; a shaft adapted to fit within the second barrel, the shaft being movable longitudinally within and with respect to the second barrel, the shaft having a distal end which is engageable and disengageable with an aperture in the second barrel; a device for controlling engaging and disengaging of the distal end of the shaft with the aperture of the second barrel. The first chamber, the second chamber and the third chamber may be selectively moved to receive and discharge fluids with respect to one another.

An apparatus is including a negative pressure wound therapy pump including a pump housing; and a negative pressure wound therapy canister attached to and readily removable from the pump housing; the canister including a flexible conduit; the canister operable to receive suction generated by the pump; the flexible conduit sized, shaped, and located to interface with the pump housing of the pump such that suction produced by the pump is transmitted to the canister via the flexible conduit.
