Abstract
Description
Technical Field
[0001] The invention relates to a medical gauze-wrapped cotton pad dressing and a preparation method thereof, belonging to the technical field of medical dressings. Background Art
[0002] Medical cotton gauze pad is a kind of dressing widely used in the medical field, with the following main application areas: 1. Operating room: used to cover wounds during surgery, reduce bleeding, provide protection, and help healing. It can be used to wrap and pad the surgical site to prevent bleeding. It can also protect the wound from external contamination or foreign body invasion; 2. Wards and ambulances: as a common dressing, it is used to stop bleeding, cover wounds, absorb wound exudate, keep wounds clean, and promote healing; 3. Home wound dressing and emergency treatment: used to stop bleeding, cover wounds, and absorb wound exudate; 4. Ophthalmology, rhinology, stomatology, etc.: used for disinfection and hemostasis.
[0003] The main function of the medical cotton gauze pad is to absorb blood and tissue fluid. It has better fluid absorption and can better absorb the patient's blood and tissue fluid without exerting any pressure on the wound. At the same time, it can also protect the tissue around the wound and prevent the tissue from being infected.
[0004] For example, the utility model patent with authorization announcement number CN 204050037 U discloses a composite hydrocolloid medical dressing, including an isolation layer and a hydrocolloid layer. A liquid-absorbing core is provided in the hydrocolloid layer, and a bacteria-proof layer is provided on the back. The bacteria-proof layer is mainly composed of a polyurethane film coated with viscose. The bacteria-proof layer is bonded to the edge of the hydrocolloid layer to cover the hydrocolloid layer.
[0005] However, the absorption capacity of hydrocolloid dressings is limited, and for highly exudative wounds, the adhesion effect of the antibacterial layer will also decrease, making it difficult to play a good isolation role. Summary of the invention
[0006] The present invention aims to solve the above problems, thereby providing a medical gauze-wrapped cotton pad dressing. The medical gauze-wrapped cotton pad dressing of the present invention solves the problem that the cotton pad has a reduced dressing effect on the wound surface of the body after absorbing moisture by setting a gauze bandage.
[0007] The technical solution of the present invention to solve the above problems is as follows: A medical gauze-wrapped cotton pad dressing comprises a cotton pad, wherein the cotton pad comprises a cotton block and the cotton-wrapped gauze wrapping the cotton block, and the cotton pad further comprises a water-repellent film arranged between one surface of the cotton block and the cotton-wrapped gauze; the medical gauze-wrapped cotton pad dressing further comprises a gauze bandage for fixing the cotton pad.
[0008] As a preferred embodiment of the above technical solution, the gauze bandage is fixed to the cotton-wrapped gauze by sewing.
[0009] As a preferred embodiment of the above technical solution, the medical gauze-wrapped cotton pad dressing is a compressed body, and the volume of the compressed body is 1 / 5 to 1 / 2 of the usage volume.
[0010] As a preferred embodiment of the above technical solution, the medical gauze-wrapped cotton pad dressing further comprises a fixed paper ring for binding the compression body to limit expansion, and two ends of the fixed paper ring are overlapped by adhesive tape.
[0011] As a preferred embodiment of the above technical solution, the medical gauze-wrapped cotton pad dressing further includes a plastic packaging film for vacuum packaging the compressed body to further limit expansion.
[0012] As a preferred embodiment of the above technical solution, the cotton block is combed cotton, and the cotton-wrapped gauze and gauze bandage are pure cotton absorbent gauze.
[0013] As a preferred embodiment of the above technical solution, the water-repellent film is a PE film, a PP film, a PET film or a PU film.
[0014] Another object of the present invention is to provide a method for preparing the medical gauze-wrapped cotton pad dressing.
[0015] A method for preparing a medical gauze-wrapped cotton pad dressing comprises the following steps: S1. Provide a gauze and a cotton block, and pad the gauze under the cotton block; S2, providing a plastic film, and spreading it on the cotton block; S3, turning up the gauze on all sides and covering the cotton block and the plastic film to form a cotton-wrapped pad preform; S4, sewing the cotton-wrapped pad preform to make a cotton-wrapped pad; S5, providing a gauze bandage, and suturing the middle portion of the gauze bandage and the cotton-wrapped pad; S6, folding the gauze bandage and attaching it to both sides of the cotton-wrapped pad to form a gauze-wrapped cotton pad dressing preform; S7, compressing the gauze-wrapped cotton pad dressing preform to 1 / 5 to 1 / 2 of its original volume with a compressor, then taking it out, and wrapping it with a fixed paper ring for at least one week to form a bundle; S8, putting the bundle into a plastic sealing bag, and then vacuum-sealing the plastic sealing bag with a plastic sealing machine to obtain a medical gauze-wrapped cotton pad dressing.
[0016] As a preferred embodiment of the above technical solution, in step S4, the sewing process is performed by using an overlock machine to perform the sewing process while overlocking, or by using an overlock machine to perform the sewing process after overlocking.
[0017] As a preferred embodiment of the above technical solution, in step S5, the suturing process is performed using a sewing machine.
[0018] In summary, the present invention has the following beneficial effects: 1. The present invention solves the problem that the dressing effect of the cotton pad on the wound surface decreases after the cotton pad absorbs moisture by providing a gauze bandage; 2. The present invention provides a water-repellent film between one surface of the cotton block and the cotton-wrapped gauze, thereby solving the problem of the cotton block wetting the clothes after absorbing liquid, and keeping the surface of the dressing dry; 3. The present invention solves the problem of large space occupied by the dressing during storage and transportation by compressing and plastic-sealing the dressing. The vacuum plastic sealing also has a good antibacterial effect and is also very helpful for the preservation of the dressing. BRIEF DESCRIPTION OF THE DRAWINGS
