A vented chest wound seal for a penetrating chest wound includes a flexible sheet including a top surface and a bottom surface, an adhesive hydrogel layer covering a portion of the bottom surface of the flexible sheet, and a plurality of vent channels. The adhesive hydrogel layer includes an inner perimeter and an outer perimeter, and the outer perimeter forms a continuous perimeter of hydrogel along a bottom surface of the flexible sheet. A plurality of vent channels, each including a first opening to a space inside of the inner perimeter, extend radially outward to an outer terminal end vent to the top surface of the flexible sheet. The outer terminal end is spaced apart from the outer perimeter of the adhesive hydrogel layer towards the central portion of the chamber.

A chest wound seal for treating traumatic pneumothorax following a penetrating chest wound. The chest wound seal comprises a wound pad with an absorbent bottom surface and a nonporous top surface embedded with unidirectional valves that allow evacuation of air and fluid from the pleural cavity but prevents re-entry of air into the thorax. A central vacuum column mounted over at least one unidirectional valve. The chest wound seal further comprises a plurality of wound pad segments radiating from the central vacuum column, wherein each segment comprises at least one manual valve configured to create a separate sealed area against the skin surface to suit body types with different size and morphological features. The central vacuum column is adapted to be connected to a vacuum pump which enables evacuation of harmful air and fluid from the pleural cavity thereby reducing the shock induced by hypoxia and increasing patient survivability.

The present invention is a decompression needle assembly having a needle that is removable received into to a catheter. The catheter can include a rigid portion and a deformable portion wherein the deformable portion can be multi-ported at its distal end. A one-way valve contained in a catheter hub attached to the catheter wherein the one way valve is in an open position when the needle is received in the catheter. Lateral catheter openings can be defined in the catheter and disposed adjacent to a distal end of the catheter. A plunger can be received within the needle and have an visual and auditory indicator that can be appreciated through the needle hub.

A non-invasive tissue oxygenation system for accelerating the healing of damaged tissue and to promote tissue viability is disclosed herein. The system is comprised of a lightweight portable electrochemical oxygen concentrator, a power management system, microprocessors, memory, a pressure sensing system, an optional temperature monitoring system, oxygen flow rate/oxygen partial pressure monitoring and control system, a display screen and key pad navigation controls as a means of providing continuous variably controlled low dosages of oxygen to a wound site and monitoring the healing process. A kink resistant oxygen delivery tubing, whereby the proximal end is removably connected to the device and the distal end with holes or a flexible, flat, oxygen-permeable tape is positioned at or near the wound bed as a means of applying near 100% pure oxygen to the wound site. The distal end of the tube is in communication with the electrochemical oxygen concentrator and wound monitoring system to communicate oxygen partial pressure and, where appropriate, temperature information. A moisture absorbent dressing is positioned over the distal end of the tubing at the wound site and a reduced moisture vapor permeable dressing system is positioned whereby covering the moisture absorbent dressing, distal end of tubing and wound site creating a restricted or occluded airflow enclosure. The restricted airflow enclosure allows the out-of-the-way control and display unit to provide a controlled hyperoxia and hypoxia wound site for accelerated wound healing.

A device for minimizing obstruction in a medical device that carries fluids includes a housing defining a channel configured to receive and secure a section of the medical device such that the section of the medical device extends coaxially with a central longitudinal axis of the channel. The device also includes components supported in the housing, including a motor, wherein the components are configured to be operated to impart motion to the housing and the attached medical device. The motion is configured to produce oscillatory motion of a frequency sufficient to concentrate shear stresses in a fluid boundary layer adjacent an inner wall of the medical device. The housing and the components supported in the housing are configured and arranged so that a device center of mass lies along or near the longitudinal axis of the channel.
