Description

A hygroscopic and breathable medical elastic tape

technical field

The utility model relates to a medical elastic adhesive tape used for superficial wound closure.

Background technique

The content of the background art is only to help understand the technical content, and is not the prior art.

Superficial skin wounds usually refer to wounds formed by injuring the epidermis and superficial layers of the dermis. This type of wound is common clinically, and most of them are located on exposed positions of the body such as the face and limbs. If the wound does not heal well, it is easy to leave scars. Correct and timely wound treatment can help the wound heal better and reduce sequelae.

Medical elastic tape provides a simple and non-invasive method to close small traumas up to 5cm in width. Medical elastic tape is composed of rayon non-woven tape, transparent silicone film, silicone double-sided tape, multi-layer tape, release paper and release lining. When the tape is in use, the transparent silicone film is stretched, and then the man-made fiber non-woven tape is adhered to the patient's skin, and the wound is closed by the pulling force of the transparent silicone film. The disadvantages of this medical elastic tape are: 1. There will be exudate flowing out during the wound recovery process, and the exudate will cause the bonding failure, thereby affecting the healing of the wound. 2. When the above-mentioned medical elastic tape is used with superficial wound dressing, the wound dressing needs to be placed on the transparent silicone film. The wound dressing cannot absorb the exudate, and the exudate will still cause the adhesive failure of the double-sided silicone adhesive, thus affect wound healing. 3. When this medical elastic tape is used for deep wounds, it is necessary to use other wound dressings on the deep wounds. After the wound dressings fill the deep wounds, the wound dressings are fixed with medical elastic tapes. At this time, the medical elastic tapes lose their tension. The role of tightening the wound only acts as a fixed dressing.

Utility model content

The purpose of the utility model is to provide a medical elastic adhesive tape with dressings that can tighten wounds, promote wound healing, and effectively ensure wound healing.

The medical elastic tape comprises an elastic layer, two ends of the elastic layer are respectively connected with the tape, the front side of the tape is provided with release paper, and the back side of the tape is provided with a release lining. The release paper indicates the upper limit of the stretched length of the elastic layer. The tape is conventional tape with glue on one side and no glue on the other side. The release lining is arranged on the adhesive side of the tape, and the release paper is fixed on the non-adhesive side of the tape through double-sided tape. There is no connection relationship with the tape and the elastic layer, and the elastic layer can freely expand and contract within the range limited by the release paper. The function of the release liner is to protect the adhesive layer of the tape and the surface of the elastic layer against the patient's skin from contamination.

In clinical use, it is found that the 0.14mm thickness of the silicone membrane is basically not breathable, and the silicone membrane of this specification is expensive, requires high processing accuracy, and the process of making the silicone membrane into an elastic tape is complicated. The third aspect of the present invention aims to provide a medical elastic adhesive tape that utilizes the existing dressing materials to achieve moisture absorption and ventilation, and can provide elastic force to tighten the wound.

As a preferred solution, the elastic layer includes a polyurethane film and a foam dressing, one side of the polyurethane film is glued, and the glued surface of the polyurethane film is bonded to the foam dressing. The thickness of the polyurethane film is thin, it is not easy to be pulled off, and it can support the deformation of the foam dressing. The foam dressing itself has a certain elasticity, and under the support of the polyurethane film, it can remain intact without breaking after moisture absorption, and continuously provide the elasticity required for closing the wound.

Preferably, the thickness of the polyurethane film is 0.02mm-0.05mm. The advantages of polyurethane film are that it is thin, has good toughness, is not easily broken, and is cheap and easy to obtain. The laminating process of polyurethane film is simple. The thickness of the polyurethane film refers to the thickness of the polyurethane film and the adhesive layer.

Preferably, the adhesive surface of the adhesive tape is bonded to the polyurethane film, and two ends of the elastic layer are respectively provided with a piece of adhesive tape. The part of the polyurethane film that is not covered with the tape is used as the elastic part.

Preferably, the adhesive surface of each tape is covered with its own release lining; a dressing protection layer is arranged between the two pieces of release lining, and the dressing protection layer completely covers the foam dressing. The release liner protects the adhesive layer of the tape from contamination, and the dressing protector protects the surface of the foam dressing from contamination.

Preferably, both ends of the protective layer are respectively bonded with two tapes. When using, first tear off the protective layer, and expose the glue section originally covered by the protective layer on the tape, then hold the tape with the release lining with both hands, stick one end of the tape on the patient's skin, and stick and fix the glue section on the patient's skin Then pull the elastic layer apart, stick the other end of the elastic dressing on the patient's skin, and finally remove all the release lining, and the tape is completely adhered to the patient's skin.

Preferably, the sum of the lengths of the release lining and the protective layer at both ends is equal to the length of the elastic tape in the natural state of the elastic layer.

Preferably, the tape is a non-woven tape, or a medical cloth tape, or a transparent and breathable medical tape, or a pressure-sensitive medical tape.

The advantage of the utility model is that the elastic layer is used to provide the pulling force required to close the wound, and the dressing can absorb the exudate of the wound and maintain the adhesion stability between the elastic tape and the skin. The dressing is hygroscopic and breathable. After the dressing absorbs the exudate, it provides a moist healing environment for the wound, which is conducive to wound healing.
