Description

Technical Field

[0001] This application relates to the technical field of medical drapes, and particularly to a degradable antibacterial medical drape. Background Art

[0002] Medical drapes, also known as surgical drapes, are infusion, nursing, and protective devices used in operating rooms. Their main function is to provide a clean and sterile working environment for the surgical process and protect the surgical area from external contamination. Surgical drapes are characterized by good water absorption and adsorption properties, capable of quickly absorbing and fixing secretions such as blood and body fluids in the surgical area to prevent their spread and contamination of the surgical area. At the same time, surgical drapes also have good breathability, capable of maintaining ventilation in the surgical area and reducing the discomfort of surgical personnel. Surgical drapes are usually made of pure cotton or synthetic fiber materials, with the characteristics of being soft and comfortable, and will not cause irritation or discomfort to the surgical area. They are also specially treated, such as high-temperature sterilization, to ensure their aseptic performance.

[0003] Existing drapes require several laying operations around the surgical opening during use to ensure that the drapes can cover as much of the non-surgical area as possible and avoid contamination of the surgical area by the outside world. However, the multi-layer laying operation is relatively cumbersome during use. And to ensure the adsorption effect on liquids, it is necessary to pay attention to laying each drape closely against the outside of the surgical area during laying, which increases the work difficulty of medical staff. In addition, the constituent materials of the drapes generally do not have degradability, which will cause great pressure on the environment. Therefore, in view of the above problems, a degradable antibacterial medical drape is proposed herein. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, this application provides a degradable antibacterial medical drape, which overcomes the deficiencies of the prior art and aims to solve the problems of inconvenient laying operation, time-consuming and laborious of drapes, and poor degradability of drapes that are likely to increase the environmental burden.

[0005] To achieve the above object, this application provides the following technical solutions:

[0006] A degradable antibacterial medical drape includes a degradable antibacterial base cloth. A detachable adsorption pad is provided on the back of the degradable antibacterial base cloth. The adsorption pad includes several groups of annular pad strips. Cutting lines are printed at the gaps between the annular pad strips on the back of the degradable antibacterial base cloth. The annular pad strip includes a cotton strip, and a gauze sleeve layer is sleeved outside the cotton strip, and a skin-touching layer is adhered to the gauze sleeve layer through an adhesive layer.

[0007] By adopting the above technical solution, the surgical area can be directly covered by the provided annular cushion strip, and an appropriate cutting line can be selected according to the size of the surgical area to cut the degradable antibacterial base cloth, so as to leave an opening for the operation. This method can complete the covering work of the surgical area relatively quickly, improve the laying efficiency, and the annular cushion strip can surround the surgical area and absorb the flowing liquid, improving the sanitary environment. In addition, the degradable antibacterial base cloth can play a certain antibacterial role and can be degraded relatively efficiently when discarded, reducing the environmental burden.

[0008] As a preferred technical solution of the present application, the degradable antibacterial base cloth includes a degradable fabric, and the degradable fabric is a polylactic acid fiber fabric.

[0009] By adopting the above technical solution, since the main material constituting the degradable antibacterial base cloth is the degradable fabric, the degradable antibacterial base cloth can be decomposed by microorganisms into water and carbon dioxide in the natural environment, thus reducing the pressure on the environment.

[0010] As a preferred technical solution of the present application, an antibacterial layer is evenly sprayed on the front end face of the degradable fabric, and the antibacterial layer is a contact-killing antibacterial coating containing substances with bactericidal or bacteria-activity-inhibiting properties.

[0011] By adopting the above technical solution, the degradable antibacterial base cloth can be made to have an antibacterial effect, avoiding the infection of the surgical opening by bacteria in the external environment.

[0012] As a preferred technical solution of the present application, a plurality of annular hook surfaces of Velcro are fixedly arranged on the rear end face of the degradable fabric, and a loop surface of Velcro is fixedly arranged on the gauze sleeve layer.

[0013] By adopting the above technical solution, a detachable connection between the degradable antibacterial base cloth and the adsorption pad can be realized. During cleaning, the degradable antibacterial base cloth can be separated from the adsorption pad, facilitating the respective cleaning work.

[0014] As a preferred technical solution of the present application, the skin-touching layer is an annular sheet layer structure made of transparent silica gel material.

[0015] By adopting the above technical solution, the comfort level when the annular cushion strip contacts the human body can be improved with the skin-touching layer made of silica gel material, thereby improving the satisfaction of the patient.

[0016] As a preferred technical solution of the present application, the adhesive layer is a biodegradable adhesive mainly using a degradable polymer as the matrix resin.

[0017] By adopting the above technical solution, the adhesive layer can be made to have degradable characteristics, further improving the degradability of the overall drape.

[0018] As a preferred technical solution of the present application, both the tampon and the gauze sleeve layer are made of cotton. The tampon is a strip-shaped structure pressed from cotton, and the gauze sleeve layer is a porous mesh cloth structure.

[0019] By adopting the above technical solution, since the cotton material can be degraded by microorganisms in the natural environment, both the tampon and the gauze sleeve layer have the characteristics of being degradable, which can further improve the degradability of the overall drape.

[0020] Advantages of the present application: The provided annular cushion strip can directly cover the entire surgical area, and the appropriate cutting line can be selected according to the size of the surgical area to cut the degradable antibacterial base cloth, so as to leave an opening for the operation. This method can complete the covering work of the surgical area relatively quickly and improve the laying efficiency; and the annular cushion strip can surround the surgical area and absorb the flowing liquid, improving the sanitary environment; in addition, the degradable antibacterial base cloth as the main body can play a certain antibacterial role and can be degraded relatively efficiently when discarded, reducing the environmental burden.

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] Refer to Figure 1-2, A degradable antibacterial medical drape, comprising a degradable antibacterial base cloth 1. A detachable adsorption pad 2 is arranged on the back surface of the degradable antibacterial base cloth 1. The adsorption pad 2 includes several groups of annular pad strips 21. Cutting lines 11 are printed at the gaps between the annular pad strips 21 on the back surface of the degradable antibacterial base cloth 1. By adopting the above technical solution, the set annular pad strips 21 can directly cover the surgical area, and the appropriate cutting line 11 can be selected according to the size of the surgical area to cut the degradable antibacterial base cloth 1, so as to realize leaving an opening for the operation. This method can complete the covering work of the surgical area relatively quickly, improve the laying efficiency, and the annular pad strips 21 can surround the surgical area and absorb the flowing liquid, improving the sanitary environment. In addition, the degradable antibacterial base cloth 1 can play a certain antibacterial role and can also be degraded relatively efficiently when discarded, reducing the environmental burden.

[0028] Refer to Figure 3 , The annular pad strip 21 includes a cotton strip 211. A gauze sleeve layer 212 is sleeved outside the cotton strip 211. A skin-touching layer 213 is bonded to the gauze sleeve layer 212 through an adhesive layer 214. The flowing liquid can be adsorbed by the cotton strip 211 and the gauze sleeve layer 212 to prevent it from flowing out of the area surrounded by the annular pad strip 21, improving the surgical environment.

[0029] Refer to Figure 4 , The degradable antibacterial base cloth 1 includes a degradable fabric 101. The degradable fabric 101 is a polylactic acid fiber fabric. Since the main material constituting the degradable antibacterial base cloth 1 is the degradable fabric 101, the degradable antibacterial base cloth 1 can be decomposed into water and carbon dioxide by microorganisms in the natural environment, thus reducing the pressure on the environment. In addition, an antibacterial layer 102 is evenly sprayed on the front end surface of the degradable fabric 101. The antibacterial layer 102 is a contact-killing antibacterial coating containing substances such as metal ions and antibacterial agents that can kill bacteria or inhibit the activity of bacteria. This structural form can enable the degradable antibacterial base cloth 1 to have an antibacterial effect and prevent bacteria in the external environment from infecting the surgical opening.

[0030] Refer to Figure 2 , A number of annular hook surfaces 31 are fixedly arranged on the rear end surface of the degradable fabric 101, and loop surfaces 32 are fixedly arranged on the gauze sleeve layer 212. By adopting the above technical solution, the detachable connection between the degradable antibacterial base cloth 1 and the adsorption pad 2 can be realized. When cleaning, the degradable antibacterial base cloth 1 and the adsorption pad 2 can be separated, facilitating the respective cleaning work.

[0031] Refer to Figure 3, the skin-touching layer 213 is a ring-shaped sheet structure made of transparent silica gel. The skin-touching layer 213 made of silica gel can improve the comfort level when the ring-shaped cushion strip 21 contacts the human body, thereby improving the satisfaction of patients. In addition, the adhesive layer 214 is a biodegradable adhesive mainly using degradable polymers such as polyesters, polyurethanes, and polyamides as matrix resins. This structural form enables the adhesive layer 214 to have degradable characteristics and further improves the degradability of the overall drape.

[0032] Refer to Figure 3 , both the cotton strip 211 and the gauze sleeve layer 212 are cotton structures. The cotton strip 211 is a strip structure pressed from cotton, and the gauze sleeve layer 212 is a porous mesh cloth structure. By adopting the above technical solution, since cotton materials can be degraded by microorganisms in the natural environment, both the cotton strip 211 and the gauze sleeve layer 212 have degradable characteristics, which can further improve the degradability of the overall drape.

[0033] Working principle: During laying, select an appropriate cutting line 11 to cut the degradable antibacterial base cloth 1 according to the size of the surgical area, leaving enough operating openings for the operation. At the same time, the set ring-shaped cushion strip 21 directly covers the entire surgical area to achieve the function of dividing and protecting the surgical area. This method can complete the covering work of the surgical area relatively quickly, improving the laying efficiency. The cotton strip 211 and the gauze sleeve layer 212 in the ring-shaped cushion strip 21 adsorb the flowing liquid to prevent it from flowing out of the area surrounded by the ring-shaped cushion strip 21, improving the surgical environment and avoiding the infection of other parts of the body. The surface of the degradable antibacterial base cloth 1 is sprayed with an antibacterial layer 102, which enables the degradable antibacterial base cloth 1 to have antibacterial effects and prevent bacteria in the external environment from infecting the surgical opening.

[0034] In addition, the main material constituting the degradable antibacterial base cloth 1 is a degradable fabric 101, so the degradable antibacterial base cloth 1 can be decomposed into water and carbon dioxide by microorganisms in the natural environment. Both the cotton strip 211 and the gauze sleeve layer 212 are cotton structures and can be degraded by microorganisms in the natural environment. At the same time, the adhesive layer 214 is a biodegradable adhesive mainly using degradable polymers such as polyesters, polyurethanes, and polyamides as matrix resins and also has degradable characteristics. Most of the structures constituting the drape can be degraded by the natural environment, so the overall drape has good degradable characteristics and can reduce the burden on the environment during use.

[0035] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
