  • Publication number: 20230226269
    Abstract: A method of analyzing fluid collected from a wound site, the method comprising the steps of: (a) providing a pump unit comprising: one or more pumps, one or more fluid collectors, and one or more drainage structures each in communication with an exit site of the wound site to draw the fluid through the one or more drainage structures into the pump unit and create a negative pressure at the exit site to remove and transport the fluid from the exit site and into the one or more fluid collectors, wherein the pump unit is configured to create a negative pressure, wherein the fluid removal from the exit site is provided at a controlled and measured rate; b) collecting the fluid within the one or more fluid collectors; c) removing the one or more fluid collectors; e) capping the one or more fluid collectors with a cap; and d) analyzing the collected fluid of step “b” once the fluid connectors are removed in step “c”.

  • Patent number: 11577017
    Abstract: 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.

  • Publication number: 20230001069
    Abstract: 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.

  • Publication number: 20210310476
    Abstract: A device comprising: (a) a housing; (b) one or more pumps located within the housing, the one or more pumps configured to create a negative pressure and move fluid; (c) one or more connectors located at least partially within in the housing; (d) internal fluid paths connecting the one or more pumps to the one or more connectors; (e) one or more reservoirs connected to the one or more connectors, the one or more reservoirs being configured to collect the fluid moved by the one or more pumps; and (f) a processor configured to:(i) calculate a total volume of fluid collected in the one or more reservoirs; and (ii) indicate that the one or more reservoirs are full; wherein the fluid moved is a fluid from a wound or incision.
