A pump, including a compression compartment configured to receive, between first and second sides of the compartment, a flexible container holding a fluid and having an outlet; The pump also has a pump mechanism that is coupled to drive the first and second sides of the compartment together so as to force the fluid out of the container through the outlet. There are first and second electrodes the are fixed respectively to the first and second sides. The pump also includes a processor that is coupled to measure a capacitance between the first and second electrodes and to estimate, responsively to the capacitance, a volume of the fluid remaining in the container.

The invention relates to a method for filling an inflatable catheter balloon of a device for transanally introducing an infusion into the rectum or colon of a patient by means of a filling device, wherein a fill volume or a filling pressure prevailing in the catheter balloon is until there occurs a gradual, user-controllable, pneumatically initiated expansion of portions of the bowel wall, thus triggering a coordinated defecation reflex, wherein the timing and intensity of the triggering stimulus can be determined to the greatest possible extent by the user.

The invention relates to a device for transanally introducing an infusion into the rectum or colon of a patient, said device comprising a catheter with a catheter shaft wherein, to ensure the most practicable catheter insertion possible, the catheter shaft is equipped in the proximal, preanal region with gripping depressions to accommodate the fingers gripping the catheter during insertion.

A hydration system comprising: a fluid reservoir comprising a means for reversibly mounting the hydration system to a structure; a supply tube fluidly coupled to the reservoir at its distal end; a reversibly compressible chamber fluidly coupled to the supply tube; a mouthpiece proximate to or at a proximal end of the collapsible chamber; and at least two valves that regulate the flow of fluid through the hydration system, wherein a distal valve is positioned at a distal end of the chamber or along the supply tube and closes in response to compression of the chamber to reduce backflow of fluid into the reservoir during compression, and a proximal valve is positioned at the mouth piece, biased closed for regulating the delivery of fluid out of the mouthpiece and prevents or reduces air induction into the mouthpiece.

The invention relates to a device for transanally introducing an infusion into the rectum or colon of a patient, said device comprising a catheter with a catheter shaft and an inflatable balloon, comprising a distal terminal balloon section of larger radius and generally spherical or discoid shape, and, disposed proximal to this distal terminal balloon section, a tapered balloon section having a reduced radius, the tapered balloon section of the device being adapted to be placed transanally, such that the enlarged distal terminal balloon section is placed intrarectally wherein the balloon is fixed onto the catheter shaft only at fixation points located at the ends of the balloon, wherein both balloon ends taper approximately to a shaft dimension of the catheter shaft supporting the balloon; according to the present invention, the difference between the larger radius of the distal terminal balloon section and the reduced radius of the proximally adjacent, tapered balloon section is either in the pressurized state of the balloon at 30 mbar, smaller than the difference between the larger radius of the distal terminal balloon section and the reduced radius of the proximally adjacent, tapered balloon section in the pressurized state of the balloon at 100 mbar, or is in the inflated, but unpressurized state of the balloon greater than the distance between the distal end of the catheter shaft on the one hand and the distal fixation point of the balloon to the catheter shaft on the other hand.

The subject invention provides novel and highly effective methods and devices for convenient and effective wound irrigation.

This invention relates to new apparatuses for draining material from a stomach and infusing fluid into the stomach comprising a tubing connector, a housing unit, and a one-way valve. In an embodiment the connector can have a first port, a second port, a third port and a branched lumen that extends through each of the first, second and third ports. The housing unit can have a housing lumen that is sized and shaped to receive the third port and the housing unit is sized and shaped to receive the connector. The one-way valve can be sized and shaped to be received in the housing lumen.

Provided is a container for connection to a device for suctioning bodily fluids and for supplying a fluid substance to a human or animal body, said container comprising an interior which is divided into a first region for collecting the suctioned bodily fluids and into a second region for providing the fluid substance, The first region of the interior is separated from the second region by means of a flexibly realized partition wall.

Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.
