A medical dressing including: a flexible base layer including a front surface configured to face a skin of a patient and a back surface opposite the front surface, wherein the flexible base layer includes a first opening; an adhesive layer on the front surface of the base layer; a flexible cover layer entirely covering the opening of the base layer; a flexible intermediate layer sandwiched between the base layer and the cover layer, wherein the base layer, cover layer and intermediate layer joined together along an annular pattern extending entirely around the first and second openings, wherein the annular pattern joints the base layer to the intermediate layer entirely around the first and second openings, and the annular pattern joins the layers around the first and second openings except at slots extending beyond an outer edge of the cover layer and ending before an outer edge of the intermediate layer.

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.

A method of pressure control in the pneumatic compression bandage and a pneumatic compression bandage includes a cuff with a chamber to be filled with a pressurized fluid. The device has a harness to fasten the cuff in the wound area and a control and pumping unit (6) connected pneumatically to the chamber in the cuff via a hose. The unit includes an electrical pump, an electromechanical valve connected electrically with the unit, a pressure sensor connected electrically with the unit (6). The controller of the pressure in the cuff chamber is of the PID type, including a proportional, integral and derivative modules, to control the electric pump to increase pressure in the cuff chamber and to control the valve to reduce pressure in the cuff chamber.

A compression garment is disclosed. The garment can include a body dimensioned to wrap at least partially around a length of a torso of a user. A plurality of tension bands can be positioned along the body. The garment can include at least one shoulder strap, wherein the shoulder strap is operable to wrap over the shoulder of the user to hold the garment in position.

A medical dressing to treat sucking chest wound, and methods of forming the medical dressing. The methods include the steps of overlaying a cover layer on an intermediate layer and the intermediate layer on a base layer such that openings in the intermediate and base layers are aligned and the cover layer overlays the openings; fusing together the cover layer, the intermediate layer and the base layer by applying an annular welding tool face to at least one of the cover layer and base layer and applying welding energy to the template; and applying an adhesive layer on a side the base layer opposite to the intermediate layer, wherein the adhesive layer extends entirely around the opening.

Provided is a nipple patch for covering a male nipple. The nipple patch includes a spider film with an orb web structure to enhance nipple coverage and a finishing film to maximize the coverage of the nipple patch. In addition, the nipple patch provides a soft feel, enables the skin to move freely, and can be easily attached to skin around the nipple. The nipple patch includes a shield covering and protecting a nipple, a flexible adhesive film having adhesion to the skin around the nipple and having a center portion to which the shield is attached, and a spider film attached to a rear surface of the adhesive film, having lower flexibility than the adhesive film, and having an orb web structure to prevent the adhesive film from being stretched.

A pressure bandage including an elastic sheet having a first coefficient of elasticity and an adhesive side. The pressure bandage may also include a resilient pad having a second coefficient of elasticity and affixed to the adhesive side of the elastic sheet. The elastic sheet has a first predetermined shape that is configured to be applied to a corresponding anatomical location on the body of a patient. The first coefficient of elasticity and the second coefficient of elasticity are related such that, when the elastic sheet is stretched and adhered to the body of the patient, the resilient pad applies a predetermined amount of pressure to the body of the patient.

A chest wall negative pressure support device, comprising a plastic support body (1) attached to the outer side of a chest wall in a sealed mode. A flow guide groove (2) is formed in the middle of the side surface of the plastic support body (1) in contact with the outer side of the chest wall, and a negative pressure aspirator (3) is provided on the side surface of the plastic support body (1) away from the outer side of the chest wall. An air inlet of the negative pressure aspirator (3) is communicated with the flow guide groove (2) by means of a negative pressure air outlet (4) formed in the plastic support body (1), and an exhaust port of the negative pressure aspirator (3) is communicated with an exhaust pipe (5). The plastic support body (1) is tightly attached to the outer side of the chest wall in a sealed mode, the plastic support body (1) forms an outer bracket on the outer side of the chest wall to simulate ribs for supporting, swing of a mediastinum is prevented, and the process of an on-site treatment operation is simple. In addition, the chest cavity of a patient cannot be compressed, secondary injury to the patient cannot be caused, and the pain of the patient is greatly relieved.

A compression garment is disclosed. The garment can include a body dimensioned to wrap at least partially around a length of a torso of a user. A plurality of tension bands can be positioned along the body. The garment can include at least one shoulder strap, wherein the shoulder strap is operable to wrap over the shoulder of the user to hold the garment in position.
