The utility model provides a medical protection film, includes the PU membrane, dressing and dialysis paper, PU membrane one side is provided with medical pressure-sensitive adhesive, PU membrane middle part is provided with window district, the dressing passes through medical pressure-sensitive adhesive glues in one side of window district, dialysis paper is installed on the window district opposite side, the dressing deviates from one side of PU membrane still sets up the recess, fixed mounting has the support bar in the recess, two the support bar is installed side by side the limit portion of dressing, the terminal surface of support bar with the terminal surface of dressing flushes.

Preferably, the recess cross-section is down trapezoidal, the support bar includes ladder strip and panel, the panel mounting is in on the less one end of ladder strip area.

Preferably, the face sheet is coated with a medical pressure sensitive adhesive.

Preferably, the edge of the window area is provided with a through hole, and the dialyzing paper is connected with the through hole through a hot-line.

Preferably, release paper is further adhered to two ends of the PU film.

Preferably, the edge part of the release paper is provided with a lug.

The utility model discloses an useful part lies in: 1. a window area is arranged on the PU film corresponding to the dressing, and the dialysis paper is arranged in the window area, so that the air permeability of the protective film is improved, the suppuration of the wound protected by the dressing due to air impermeability is avoided, and the dressing can be protected by the dialysis paper, so that the dressing is prevented from being infected by external bacteria; 2. set up the recess in dressing and skin adjacent one side and be used for the installation support bar, set up two support bars along the length direction of wound, and then when avoiding hindering the person's motion, skin and protection film fold lead to the wound to burst apart, are difficult to the healing.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a medical protection film, including PU membrane 1, dressing 2 and dialysis paper 3, 1 one side of PU membrane is provided with medical pressure-sensitive adhesive, 1 middle part of PU membrane is provided with window district 11, dressing 2 passes through medical pressure-sensitive adhesive glues in one side of window district 11, dialysis paper 3 is installed on 11 opposite sides of window district, dressing 2 deviates from one side of PU membrane 1 still sets up recess 21, fixed mounting has support bar 4 in the recess 21, two support bar 4 is installed side by side the limit portion of dressing 2, the terminal surface of support bar 4 with the terminal surface of dressing 2 flushes. Specifically, in this embodiment, the PU film 1 is coated with the medical pressure-sensitive adhesive, and the PU film 1 can be adhered to the skin by using the medical pressure-sensitive adhesive, and the dressing 2 is correspondingly attached to the wound of the patient, so as to protect the wound and prevent the wound from continuously bleeding. Further, in order to prevent the protective film from being attached to the wound for a long time, the wound is not breathable and is easily suppurative, a window area 11 is arranged on the PU film 1, the window area 11 is aligned with the dressing 2 and is ventilated, and in order to prevent the dressing 2 from being infected by bacteria in the outside air, the window area 11 is covered with the dialysis paper 3 to protect the dressing 2.
