摘要： Systems, methods, and apparatuses for providing instillation therapy with a negative-pressure source are described. The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.

摘要： Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

摘要： A vacuum motor comprising a working plunger, an internal space, in which the working plunger is arranged such that it is mobile in linear direction, a resetting element that exerts, at least for part of the time, a force on the working plunger that acts in the direction of a front side of the internal space, a gas inlet opening for supplying ambient air or a compressed gas into the internal space, and a gas outlet opening for discharging the gas from the internal space. The gas outlet opening is connectable to a negative pressure source, whereby a control plunger is arranged between the working plunger and a rear side of the internal space such as to be mobile in linear direction in the internal space. The control plunger is supported as in a bearing such as to be mobile with respect to the working plunger, and a catch element and/or a spacer is arranged on said working plunger and/or control plunger, whereby the catch element, upon a motion of the working plunger towards the front side of the internal space, transfers the control plunger into the first position, and whereby the catch element or the spacer, upon a motion of the working plunger towards the rear side of the internal space, transfers the control plunger into the second position.

摘要： A flow measurement assembly includes a coupler and a flow channel. The coupler maintains a magnet and a sensor spaced from the magnet. The flow channel is positionable between the magnet and the sensor. The flow channel includes a housing having an inlet, an outlet spaced from the inlet, and a flow conduit fluidly open to the inlet and the outlet. A ferrous body is movably disposed in the conduit. The sensor is configured to detect a frequency of a change within a magnetic field as the ferrous body travels within the flow conduit between the magnet and the sensor.

摘要： A surgical fluid manager includes a pump releasably engageable to tubing and a user interface. The user interface is configured to enable finger-touch selection of a fluid flow rate through the tubing and configured to operate in at least one of a first mode or a second mode. In the first mode, the flow rate is controlled via direct selection of one of a plurality of selectable digital numeric values, while in the second mode the flow rate is controlled via user selection of one alphanumeric identifier within a scale of alphanumeric identifiers. Each respective alphanumeric identifier directly corresponds to just one instrument size within a scale of instrument sizes.
