BIDIRECTIONAL REVERSIBLE MEDICAL SKIN TENSION REDUCING CLOSER

Abstract

A bidirectional reversible medical skin tension reducing closer is provided. The closer comprises a left substrate and a right substrate, both of which are configured to be horizontally and symmetrically arranged, a left pawl and a right pawl fixedly arranged on adjacent ends of the left and right substrates respectively, and a left rack and a right rack, one end of each of which is fixedly connected to the left and right pawls respectively in an up-down side-by-side arrangement. Ratchets on the left and right pawls tilt towards the left and right substrates respectively, and the other ends of the left and right racks pass through the space beneath the right and left pawls respectively and are engaged with ratchets provided on the bottom of the right and left pawls respectively. Adhesive layers for fixing the left and right substrates onto the surface of the skin are arranged on the bottom surfaces of the left and right substrates. According to the invention, forces can be uniformly applied from two sides, and the closure degree of the closer can also be freely adjusted.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The present invention will be described below in detail with reference to the accompanying drawings.

[0028] With reference to FIGS. 1 through 3, a bidirectional reversible medical skin tension reducing closer of the present invention includes a left substrate 3 and a right substrate 4, both of which are configured to be horizontally and symmetrically arranged, a left pawl 5 and a right pawl 7 fixedly arranged on adjacent ends of the left and right substrates respectively, and a left rack 2 and a right rack 1. One end of each of the left and right racks is fixedly connected to the left and right pawls respectively in an up-down side-by-side arrangement. Ratchets 9 on the left and right racks tilt towards the left and right substrates respectively, and the other ends of the left and right racks pass through the space beneath the right and left pawls respectively and are engaged with ratchets 11 provided on the beneath of the right and left pawls respectively. Adhesive layers 10 for fixing the left and right substrates onto the surface of the human skin are arranged on the bottom surfaces of the left and right substrates.

[0029] A plurality of vent holes 6 may be provided in the left and right substrates 3, 4, and glue in the adhesive layers 10 may be hypoallergenic. These can effectively make the skin covered by the substrates breathe freely and prevent the skin from ulceration. Further, if the wound in the injured area is large and the closers of the invention are not able to be fixed on the skin only by adhering it, then the closers may be fixed in the following way: the closers may be directly adhered onto the two sides of the wound, and then a skin stapler or a surgical suture may be used to make the substrates fixed on the two sides of the wound through the vent holes 6 in the substrates so as to make the closers fixed tightly.

[0030] The ends of the left and right racks positioned in guide slots of the right and left substrates respectively are each provided with a head 8 with a lateral striped or frosted top surface.

[0031] The outer end of the each pawl is configured to be an upwardly bent, upturned eaves structure.

[0032] Materials of the left and right substrates include one of, or combinations of two or more of nylon, polyethylene, polypropylene, polyvinyl chloride or metal.

[0033] FIGS. 5 and 6 illustrate the closers of the invention being applied to a linear and a curved wound respectively. In use, the substrates are adhered onto the two sides of the wound, and then the racks are drew so as to make the tissue edges of the wound under the substrates brought together. When the racks are overdrew due to an excessive force, the pawls on the racks may be pulled to freely adjust the closure degree. According to the invention, forces can be uniformly applied from two sides, and the closure degree of the closer can be freely adjusted.

[0034] As shown in FIG. 7, when a large wound is treated, the closers of the invention may be symmetrically arranged and adhered onto the above non-woven adhesive layer, and then another non-woven adhesive layer is adhered onto the closers on the same side so as to make every single closer on the same side combined together via the two non-woven adhesive layers on the top of and at the bottom of the closers, forming an integral shape and thus assuring high fastness and stability among the closers.
