Some embodiments are directed to a system 10 for the application of topical negative pressure therapy to a site 18 on the body of a mammal. Some embodiments of the system 10 comprise a piston 22 and cylinder 24 device 12 having a self-contained power source for the generation of a reduced pressure and for aspirating the site 18. Some embodiments of the system 10 comprise a dressing 14 sealably surrounding the site 18 that can be operably connected to the device 12 by a conduit means 16 to apply the reduced pressure to the site 18.

This invention is related to wound care in humans and animals, and they reduce the use of adhesives. Also allows the process of wound dressing to be faster, easier, and applicable even with one hand. In these models, a support unit and straps are used. These straps are stretchable and attach to a zone of the hook fastener on the support on a detachable, re-attachable basis. In some models the support unit will function as the stabilizer of the system or to make the functions simpler. The main idea is used in making multiple models for use in different areas of the body. In other models the unit allows guarding the skin and wound site or for the protection of the wound. All in all, the applicant has tried to introduce units for improving the humans and animals life.

An apparatus suspends a post-amputation residuum protection device for a below the knee amputation. The suspending apparatus comprises an elongated arcuate first shell defining an open interior channel. The first shell is adapted to receive at least a portion of the residuum and the residuum protection device into the interior channel. A flexible second shell includes a circumferential wedge extending radially inwardly from a portion of an inner surface. The second shell is configured to be received within the first shell and adapted to cover the residuum adjacent to the knee. The wedge is adapted to bear against the residuum above the medial femoral condyle such that the wedge is received in the supracondylar space for suspending the residuum protection device.

A negative pressure treatment arrangement comprising a multi-layered drainage film, wherein a drainage space is formed between two layers of the drainage film, a first film layer on the wound side delimiting the drainage space comprising a first opening arrangement facilitating the admission of fluids or gases to the drainage space and a second film layer facing away from the wound that also delimits the drainage space comprising a second opening arrangement designed to discharge fluids and/or gases from the drainage space, and also comprising a fluid-tight fixing film that can be used to fix the drainage film to the skin surrounding a wound and to cover at least one area of the second opening arrangement.

A negative pressure wound dressing for use with breast incisions. The wound dressing includes a drape layer, a manifold layer, a base layer, and a reduced pressure interface. 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 perimeter defined by a first convex curved side surface defining a first lobe, a second convex curved side surface defining a second lobe, and a connecting portion between the first lobe and the second lobe. The base layer is configured to: (i) couple the drape layer to the manifold layer, and (ii) the dressing to a patient's tissue. The reduced pressure interface is integrated with the drape layer.

Systems, instruments, methods, and compositions are described involving removing a portion of the epidermis within a donor site on a subject, and harvesting dermal plugs within the donor site. An injectable filler is formed by mincing the dermal plugs. The injectable filler is configured for injecting into a recipient site on the subject.

A compression device for compressing an area of tissue surrounding a tissue opening to close the tissue opening. The device includes a compression support frame having an outer peripheral edge forming an arc whose central angle is less than 180° and greater than 45°. The device also includes a compression support and a tension member. The compression support is mounted on the compression support frame, and the tension member is selectively slidable in relation to the compression support.

A nose compression device to treat a nosebleed. The device has a wire frame with a straight middle section and two side sections angled with respect to the middle section to apply an inward compression against an outside of the person's nose. The device also includes a support member attached to the wire frame. And, a single nasal sponge attached to the body and having a central sponge portion and two opposing sponge end portions, each of said two opposing sponge end portions configured for insertion into the person's nasal passages.

A negative pressure assembly includes a drape, a sealing element, a reactor, a valve and a mechanical pump assembly. The drape and the sealing element, when applied to the skin, cooperate to define an enclosed volume. The reactor is located so as to be in fluid communication with the enclosed volume when the drape is covering the dressing site. The reactor reacts with a selected gas found in air to consume the selected gas. The valve has a first operating state in which gas is drawn from the enclosed volume through the valve. The mechanical pump assembly includes a pump chamber fluidly connectable to the enclosed volume through the valve when the valve is in the first operating state. The mechanical pump is configured to fluidly connect with the enclosed volume and draw air from the enclosed volume into the pump chamber.
