Description

Technical Field

[0001] The utility model relates to an accessory specially used for surgery or diagnosis, in particular to a head trauma debridement protective cap. Background Art

[0002] Head trauma is often caused by sharp or blunt instruments. The size and depth of the wound vary, with either regular or irregular wound edges, sometimes accompanied by skin contusions or defects. Due to the rich blood vessels of the scalp, ruptured blood vessels are difficult to close spontaneously, resulting in severe bleeding even from minor wounds and even shock. Debridement is a common surgical procedure that removes foreign matter from open wounds, excises necrotic, inactive, or heavily contaminated tissue, and sutures the wound to minimize contamination, even achieving a clean wound and primary healing, which facilitates functional and morphological restoration of the injured area. The head is a unique part of the human body due to its hair and its profuse bleeding. When the head and scalp require debridement and suturing, the hair surrounding the wound must be cut to expose the wound for draping and debridement. During the debridement procedure, disinfectant and blood often flow from the wound to the hairline, contaminating the entire scalp. This can cause discomfort after suturing and increase the risk of wound infection. This can also affect wound cleanliness after disinfection and the healing of the debridement and sutured wound, significantly increasing the risk of postoperative wound infection. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a head trauma debridement protective cap with adjustable opening size, suitable surgical field of view, prevention of disinfectant and blood contamination of scalp, and avoidance of cross infection.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a head trauma debridement protective cap, comprising a cap body, the cap body comprising a medical sterile gauze layer 1 on the inside that contacts the human scalp and a soft waterproof layer 2 on the outside, and the outer peripheral edge of the soft waterproof layer 2 is larger than the peripheral edge of the inner medical sterile gauze layer 1, the outer soft waterproof layer 2 is larger than the medical sterile gauze layer 1 and is sewn with an elastic elastic band 3 on the peripheral edge of the medical sterile gauze layer 1, the cap body composed of the medical sterile gauze layer 1 and the soft waterproof layer 2 reserves a certain amount of folds, and when expanded, it becomes a hollow hemispherical surface that matches the shape of the head and can adapt to different head sizes.

[0005] An elliptical opening 4 is provided on the top of the cap body, and tear lines 5 1-2 cm long are provided on the cap body outside the opening 4, extending along both sides of the short sides of the elliptical opening 4. The other ends of the two tear lines 5 extend toward the edge of the cap body. A waterproof membrane 6 is provided on the inner side of the periphery of the elliptical opening 4. The inner circle size of the waterproof membrane 6 is smaller than the opening 4, and the outer circle size is larger than the opening 4. One side of the waterproof membrane 6 is adhered to the inner side of the medical sterile gauze layer 1 at a position greater than or equal to the opening 4, and the other side is an adhesive layer 7 adhered to the scalp. A peeling layer 8 is provided on the adhesive layer 7. The waterproof membrane 6 is adhered to the surface of the scalp to isolate the hair and seal the edge of the prepared skin.

[0006] Furthermore, the thickness of the waterproof membrane 6 gradually decreases from the inside to the edge, and the overall structure thereof gradually changes in a parabolic manner, so that the cap body opening 4 is lower on the outside and higher on the inside after fitting to the scalp.

[0007] The beneficial effects of this application are as follows: The protective cap of the utility model can protect wounds, separate surrounding hair, keep the patient's hair and scalp clean and comfortable during and after debridement, and prevent wound infection. Specifically, the inner sterile medical gauze layer 1 is soft, skin-friendly, and breathable, meeting sweat absorption requirements, thereby improving the comfort of the human scalp. The top of the cap body is provided with an elliptical opening 4, which can expose the wound. The outer soft waterproof layer 2 can isolate disinfectant, making it easier for nurses to disinfect the wound. At the same time, disinfectant and blood will not flow into the patient's hairline and scalp, avoiding the risk of cross infection. The cap body has folds to accommodate different patient head sizes. The opening size can also be adjusted by tearing the cap body tear line according to the size of the patient's head trauma wound. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the top structure of the utility model.

[0009] Figure 2 It is a schematic diagram of the structure of the utility model when viewed from above.

[0010] In the figure: medical sterile gauze layer 1, soft waterproof layer 2, elastic band 3, opening 4, tear line 5, waterproof membrane 6, adhesive layer 7, peeling layer 8. DETAILED DESCRIPTION

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0012] like Figure 1 、 2 As shown: A head trauma debridement protective cap, including a cap body, the cap body including a medical sterile gauze layer 1 on the inside that contacts the human scalp and an outer soft waterproof layer 2, and the outer peripheral edge of the outer soft waterproof layer 2 is larger than the peripheral edge of the inner medical sterile gauze layer 1, and the outer soft waterproof layer 2 is larger than the medical sterile gauze layer 1 and is sewn with an elastic elastic band 3 on the peripheral edge of the medical sterile gauze layer 1. The cap body composed of the medical sterile gauze layer 1 and the soft waterproof layer 2 reserves a certain amount of folds, and when expanded, it forms a hollow hemispherical surface that matches the shape of the head and can adapt to different head sizes.

[0013] The cap body has an elliptical opening 4 at the top. Outside the opening 4, the cap body is provided with tear lines 5 extending 1-2 cm long along the short sides of the elliptical opening 4. The other ends of the tear lines 5 extend toward the edge of the cap body. A waterproof membrane 6 is provided on the inside of the elliptical opening 4. The inner circle of the waterproof membrane 6 is smaller than the opening 4, while the outer circle is larger. One side of the membrane, which is larger than or equal to the opening 4, is adhered to the inside of the medical sterile gauze layer 1. The other side is an adhesive layer 7 for adhesion to the scalp. The adhesive layer 7 is provided with a peeling layer 8. The waterproof membrane 6 is adhered to the scalp surface to isolate hair and seal the edge of the prepared skin. The thickness of the waterproof membrane 6 gradually decreases from the inside to the edge, forming a parabolic structure. This allows the cap body opening 4 to be lower on the outside and higher on the inside after contact with the scalp.

[0014] During use, before suturing, the patient takes a supine position, places the head on the debridement frame, shaves the hair around the patient's wound, fully exposes the patient's wound and scalp, and puts on the debridement protective cap on the patient's head. Due to the elasticity of the elastic band 3, the sealing between the cap body and the head is guaranteed, and the elliptical opening 4 of the cap body is aligned with the wound and the elliptical opening 4 is larger than the exposed part. Dry gauze is used to wipe the wound and scalp blood stains, and the peeling layer 8 around the elliptical opening 4 is torn off to adhere it to the scalp around the exposed part. If the wound area is too large, the size can be adjusted through the tearing line 5, and a disposable waterproof film is attached to the skin around the wound along the scalp and the tearing line 5. At this time, the wound can be rinsed with disinfectant water, and the rinsing liquid and blood will not flow into the patient's hairline and scalp. After rinsing is completed, a sterile hole towel can be continued to be laid for suturing. After suturing is completed, the waterproof film is torn off, the shower cap is taken off, and the wound is bandaged.
