The devices and methods shown provide for the minimization of extravasation during arthroscopic surgery. The extravasation minimization device allows a surgeon to drain excess fluids from the soft tissue surrounding the surgical field while also providing a stable surgical portal for arthroscopic surgical instruments.

A portable drain system having a subdermal drain and a container in fluid communication with the subdermal drain is disclosed. The subdermal drain is configured to drain fluid from a surgical site. The container provides a negative pressure to the subdermal drain. The container draws and receives the fluid. The container includes at least one sensor in which the at least one sensor is configured to detect at least one of fluid color, fluid volume in the container, and orientation of the container.

A collapsible, clamping and/or steerable apparatus in conjunction with negative pressure system and methods for using such an apparatus are described. Preferred embodiments of the invention have lengths and bent and/or increase their curvatures along their lengths, by preferentially contracting and transforming upon negative pressure.

Embodiments of a negative pressure wound closure system and methods for using such a system are described. Certain disclosed embodiments facilitate closure of a wound by preferentially exerting a negative pressure on tissue. Some embodiments may utilize a collapsible sheet with a plurality of cells.

A fluid control device includes a housing. The housing includes a first main plate, a second main plate, and a side plate connecting the first main plate and the second main plate. The housing has a pump chamber defined by the first main plate, the second main plate, and the side plate. The fluid control device also includes a driver, a first hole that extends through the first main plate or the second main plate, and a first recess formed in the first main plate between a center and a circumference or the second main plate between a center and a circumference.

A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site of a patient. A fluid parameter associated with applying a reduced pressure to the tissue site may be sensed. An audible fluid leak location sound may be generated in response to sensing the fluid parameter. The audible fluid leak location sound may be altered in response to sensing that the fluid parameter changes. By altering the audible fluid leak location sound in response to sensing a change of the fluid parameter, a clinician may detect location of a fluid leak at the drape by applying force to the drape. The force applied to the drape may be a clinician pressing a finger onto an edge of the drape.

Embodiments of apparatuses and methods for determining an emplacement of sensors in a wound dressing are disclosed. In some embodiments, a wound dressing includes a plurality of sensors configured to measure wound or patient characteristics. One or more processors are configured to receive wound or patient characteristics data as well as emplacement data. The received data can be used to determine an emplacement of the plurality of sensors, the wound dressing, or a wound. The sensors can include a set of nanosensors. The wound dressing can include pH sensitive ink which can be utilized for determining a placement of the wound dressing and determining a pH associated with the wound. The wound dressing can be used in a negative pressure wound therapy system.

The present application discloses surgical auxiliary equipment for sutureless closed skin incisions in the superficial fascia of the skin, comprising: a subcutaneous negative pressure drainage device comprising a catheter partially reaching into a preset depth of the inner cavity of the subcutaneous incision; an incision closing device arranged at the periphery of the skin incision; and a negative pressure device above skin arranged at the periphery of the skin incision and used for generating a negative pressure. Through the surgical auxiliary equipment of the present application, the sutureless closure of full-thickness tissues above the deep fascia of the skin can be achieved, so as to avoid transverse scars on the surface of the skin caused by suture oppression and cutting, and no suture knots are left in superficial fascia, so as to eliminate an important factor causing bacterial colonization and a main inducement leading to relapse of incision infection.

Apparatus and a method for the provision of TNP therapy to a wound are described, the apparatus comprising: a sealing membrane (504) for covering a wound to form a wound cavity (500); one end of an aspirant conduit (522) operably associated with the wound cavity, vacuum means (524) provided at a distal end of the aspirant conduit for applying a vacuum to the wound cavity; and, air bleed means (510) in fluid communication with the wound cavity. Various embodiments of air bleed port members are also described.

Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound dressing. The wound dressing can comprise an absorbent material, an electronics unit comprising a negative pressure source, the electronics unit integrated within the wound dressing and at least partially encapsulated by a flexible film. The flexible film can comprise a window or aperture configured to permit fluid communication between the absorbent material and the negative pressure source.
