A wound therapy system includes a dressing sealable over a wound, a conduit comprising a first inner diameter, coupled to the dressing, and fluidly communicable with the wound space, and a canister fluidly communicable with the conduit. A therapy unit is coupled to the canister and includes a pump, a sensor configured to measure a pressure, a valve controllable between an open position and a closed position, and a control circuit. The control circuit is configured to control the pneumatic pump to remove air to establish a negative pressure, control the valve to repeatedly alternate between the open closed positions to allow a controlled rate of airflow through the valve, receive measurements of the pressure from the sensor, and determine a volume of the wound space based on the pressure measurements. A portion of the conduit comprises a second inner diameter that is less than the first inner diameter.

A wound exudate management system includes a pump for generating negative pressure, a dressing for covering and protecting a wound of a user, a tube including an interior lumen, the tube disposed between the pump and the dressing such that the pump and the dressing are in fluid communication via the interior lumen. The dressing includes an adhesive layer for adhering the dressing adjacent the wound, a wound contact layer, a pressure dispersion layer, a plurality of layers of absorbent material disposed between the wound contact layer and the pressure dispersion layer, a backing layer having a first surface and a second surface, the first surface of the backing layer being adjacent, and in contact with, the pressure dispersion layer and the adhesive layer, and a flexible connector disposed on the second surface of the backing layer.

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.

Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. Maintenance and control of the sub atmospheric pressure exerted may be provided by such devices while minimizing discomfort to the user. The devices may be configured to be worn inconspicuously underneath clothing.

A wearable machine system includes a garment and a passive actuator mounted to the garment. The passive actuator is actuatable in response to involuntary movements of a wearer of the garment. A machine is coupled with the passive actuator such that actuation of the passive actuator responsive to the involuntary movements mechanically drives the machine.

A leech therapy device adapted to latch a medicinal leech to a predetermined wound site is provided. The leech therapy device includes a conduit extending between a first end to a second end; an inner diameter of the conduit dimensioned to receive a medicinal leech, the inner diameter being less than twice a girth of the medicinal leech; and a cutout provided in the conduit closer to the first end than the second end; the cutout extending over a surface area between 100 and 150 squared millimeters. Wherein a user places a medicinal leech into the inner diameter, wherein a head of the medicinal leech is adjacent to the cutout, and then the user selectively positions said leech therapy device so that the cutout substantially circumscribed the wound site so that the medicinal leech can engage the wound site.

A negative pressure wound treatment (NPWT) dressing system for treating shoulder incisions. The NPWT dressing system includes a wound dressing, an immobilization device configured to immobilize a shoulder of a patient, and a negative pressure source coupled to the immobilization device. The wound dressing includes a drape layer, a manifold layer, and a reduced-pressure interface integrated with the drape layer and the negative pressure source. The drape layer has a first surface and a second, wound-facing, surface. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The manifold layer has a first surface and a second, wound-facing surface. The manifold layer has a first lobe, a second lobe substantially aligned with the first lobe, and a third lobe extending substantially perpendicular to the first lobe and the second lobe.

A drain immobilization device for the securement or fixation of surgical drains during surgery or post-surgery to remove fluids accumulated in a wound site or other area, wherein instead of having the surgical tubes fastened to the patient's body by sutures or stitches the surgical tubes are held inside of a clasp, the clasp attached to a base, the base having a layer of adhesive to attach to the patient's skin.
