A system, method, and apparatus for the collection of surgical/wound fluid from a subject patient with the capability of simultaneous fluid removal from a plurality of such wounds and/or wound through the utilization of a single pump device worn by such a patient. Such a system, method, and apparatus allow for such a single pump device to collect surgical/wound fluid within a single site collection component attached to or associated with such a single pump device. Multiple fluid transfer lines may be incorporated with the single pump device leading to such plurality of wounds and/or wound sites for greater versatility and comfort for the subject patient, as well as cleaner removal capabilities than in the standard apparatus systems and method currently undertaken within the industry.

A therapy system for treating a tissue site with negative-pressure therapy and/or fluid instillation therapy in response to information received from a diagnostic module is disclosed. In some embodiments, the therapy system may include a dressing, a negative-pressure source, a container, and a diagnostic module. The dressing may be adapted to be placed on the tissue site, and the negative-pressure source may be adapted to be fluidly coupled to the dressing. The container may be adapted to be fluidly coupled to the dressing and to the negative-pressure source and to receive fluid from the tissue site. The diagnostic module may be adapted to be exposed to gas associated with the fluid from the tissue site. The diagnostic module may comprise a sensor configured to detect a condition of the tissue site and to generate an output based on the detected condition. The sensor may be configured to detect a volatile organic compound. In some embodiments, the diagnostic module may be positioned on the container.

Disclosed embodiments may relate to devices, systems, and methods for providing negative-pressure therapy simultaneously to a plurality of tissue sites using a single negative-pressure source. For example, a fluid bridge may comprise a plurality of distal ends, each configured to interact fluidly with a tissue site. In some embodiments, each distal end may have an aperture. The bridge may also comprise a port for entry of negative pressure into the enclosed space of the bridge. In some embodiments, each distal end may comprise a one-way valve. The enclosed space of the fluid pathway between the distal ends and the port may be supported in some embodiments, to prevent collapse due to negative pressure and/or compression.

A negative pressure assembly includes a drape, a sealing element, a reactor, a valve and a mechanical pump assembly. The drape and the sealing element, when applied to the skin, cooperate to define an enclosed volume. The reactor is located so as to be in fluid communication with the enclosed volume when the drape is covering the dressing site. The reactor reacts with a selected gas found in air to consume the selected gas. The valve has a first operating state in which gas is drawn from the enclosed volume through the valve. The mechanical pump assembly includes a pump chamber fluidly connectable to the enclosed volume through the valve when the valve is in the first operating state. The mechanical pump is configured to fluidly connect with the enclosed volume and draw air from the enclosed volume into the pump chamber.

System for percutaneous drainage of a drainage site includes a catheter, a drain tube, a first pump, a flush tube, a second pump, and a controller. The catheter includes a drain lumen defined by a first portion of a catheter wall and a septum, and a flush lumen defined by a second portion of the catheter wall and the septum. The flush lumen is separated from the drain lumen by the septum. The septum has at least one septal hole disposed therein such that the drain lumen and the flush lumen are in communication via the at least one septal hole. The catheter wall has at least one wall hole disposed therein such that the drain lumen is in communication with the drainage site when the distal end portion of the catheter is placed within the drainage site.

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically. Additionally, through such a peristaltic pump device, controlled collection of measured surgical and/or bodily fluid from a subject patient may be undertaken allowing for more effective and closer analysis, as well.

A negative pressure wound therapy system treats multiple wounds on a patient's body. The system includes a source of negative air pressure, an air source, first and second fluid collection volumes, first and second wound-covering domes disposed over first and second wounds, a valve assembly disposed between the source of negative air pressure and the first and second fluid collection volumes, and between the air source and the first and second domes. The valve assembly has first and second operational modes. In the first, the valve assembly puts the source of negative air pressure in fluid communication with the first fluid collection volume, and the air source in fluid communication with the first dome. In the second, the valve assembly puts the source of negative air pressure in fluid communication with the second fluid collection volume, and the air source in fluid communication with the second dome.

A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.
