Monitoring patient compliance with a compression therapy regimen. Venous Refill Time (VRT) is monitored via a pressure sensor in a bladder of a compression system. A controller of the compression system correlates the monitored VRT to a predetermined threshold to determine whether the patient is using the compression system.

Control unit for monitoring patient compliance with a compression therapy regimen

A system for subatmospheric pressure therapy in connection with healing a wound is provided. The system includes a wound dressing cover dimensioned for positioning relative to a wound bed of a subject to establish a reservoir over the wound bed in which subatmospheric pressure may be maintained, a subatmospheric pressure mechanism including, a housing, a vacuum source disposed in the housing, and a collection canister in fluid communication with the vacuum source. The system further includes an exudate conduit in fluid communication with the wound dressing and the collection canister for collecting exudate removed from the reservoir and deposited in the collection canister under influence of the vacuum source and a vent conduit in fluid communication with the collection canister and the wound dressing for introducing air into the reservoir to facilitate flow of exudate through the exudate conduit.

System for providing continual drainage in negative pressure wound therapy

Monitoring compliance using venous refill detection

A wound dressing for use in a vacuum wound therapy treatment includes a backing layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound. A portal member affixed to the backing layer provides a connection to a reduced pressure source through an opening in an ambient surface. A primary port extends between the opening and a primary aperture in a reservoir surface to providing fluid communication between the reservoir and the reduced pressure source. At least one supplemental port establishes fluid communication between the primary port and a supplemental aperture in the reservoir surface that is distinct and substantially spaced from the primary aperture.

Wound dressing port and associated wound dressing

A compression treatment system is provided that detects the number of and type of garments connected thereto. The system includes a plurality of ports, valves connected thereto and a number of garments having one or more bladders. The bladders are in fluid communication with a fluid source in a pneumatic circuit, to provide compression therapy once a user confirms the number of and type of garments connected to the system for use by a patient. A single pressure sensor communicates with a plurality of detected bladders located in the one or more garments.

Garment detection method and system for delivering compression treatment

A compression device for applying compression to a body part of a wearer has an inflatable bladder defined by first and second bladder layers and a bladder sealing line securing the first and second bladder layers to one another. A conduit is defined by spaced apart, generally opposing conduit sealing lines securing the first and second bladder layers to one another and portions of the first and second bladder layers between the conduit lines. The conduit is fluidly connected to the inflatable bladder for delivering pressurized air to the inflatable bladder. Tubing is not needed for connection to the compression device.

Tubeless compression device

A foot cuff that is inflatable to apply compression to the foot to promote blood flow has a bladder formed of two layers of material secured together. An outer layer includes a foot-underlying portion that has a greater thickness and rigidity that an opposing inner layer. The outer layer directs expansion of the bladder upon inflation in the direction of the inner layer and toward the foot for increasing compressive force applied to the foot.

Inflatable member for compression foot cuff

A method of forming a bag assembly by RF welding includes generating from a single source of RF energy a high frequency electric field having a first strength between tube-welding electrodes of opposing die members and a second strength less than said first strength between perimeter-welding electrodes of the opposing die members. Subjecting a tube assembly and corresponding portions of sheets surrounding the tube assembly to the high frequency electric field of said first strength for a predetermined amount of time to weld the sheets to a tube along a tube-weld. Corresponding portions of the sheets between the perimeter-welding electrodes are subjected to the high frequency electric field of said second strength for said predetermined amount of time to weld the sheets together along a bladder perimeter-weld. The subjecting steps are performed simultaneously so that the bag assembly is formed in one welding operation.

Apparatus for making bag assembly

A welding apparatus includes first and second die members opposing one another. The first and second die members include opposing respective first and second perimeter-welding electrodes and opposing respective first and second tube-welding electrodes. The first perimeter-welding electrode and first tube-welding electrode define a first welding surface. The second perimeter-welding electrode and second tube-welding electrode define a second welding surface. A single source of high frequency energy is electrically connected to the perimeter-welding electrodes and to the tube-welding electrodes. Dielectric material is selectively disposed on the first welding surface such that the material is disposed on some but not all the first welding surface for reducing a strength of a high frequency electric field between the first and second perimeter-welding electrodes as compared to a strength of the high frequency electric field between at least a portion of the first and second tube-welding electrodes.
