[0021] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0022] As described in the background art, the existing traumatic hemostatic bandage is likely to cause muscle atrophy in patients after being tightly bound for a long time, causing secondary harm to the patients and seriously affecting the treatment effect of the patients. At the same time, restricted by the use environment, the traumatic hemostatic bandage not only requires simple hemostasis, but also the protection and prevention of re-infection of the wound are particularly important. Therefore, this embodiment provides a waterproof traumatic hemostatic bandage.
[0023] See Figures 1 to 4 , this embodiment provides a waterproof traumatic hemostatic bandage, including a sealant layer 1, and a hemostatic mechanism 2 is arranged inside the sealant layer 1. The hemostatic mechanism 2 includes a waterproof film layer 201 adhered to the sealant layer 1.
[0024] The bottom surface of the sealant layer 1 is coated with an adhesive, and the adhesive uses a medical glue, which is safe and non-irritating and will not cause damage to the skin. It enables the hemostatic bandage to have self-adhesion, facilitating the user to quickly bandage the patient's wound, and can also maintain sufficient adhesion underwater and is not easy to fall off.
[0025] The waterproof film layer 201 is made of a polymer film material with waterproof function, which can perform waterproof sealing on the edge of the hemostatic bandage, enhance the overall waterproof performance, and prevent moisture from seeping in from the edge.
[0026] A temperature sensing layer 8 is arranged on the upper surface of the waterproof film layer 201. The temperature sensing layer 8 is divided into four color display areas. All four areas on the temperature sensing layer 8 are filled with thermochromic materials, which mainly consist of three parts: a color-changing dye, a developer, and a solvent. By regulating the solidification temperature of the solvent, thermochromic products that change color at different temperatures can be prepared. Thus, when the patient's wound becomes infected or inflamed, the hemostatic bandage makes the corresponding area display the corresponding color according to the different temperatures it senses, reminding the rescue personnel to deal with it in time.
[0027] For example, select four standards between 37° and 40°, so that the four areas of the temperature sensing layer 8 can display color change only corresponding to the four standards, that is, it can judge the temperature range of the wound by the color change of different color areas.
[0028] The bottom surface of the waterproof film layer 201 is fixedly connected with a water-absorbing cotton layer 202, and the water-absorbing cotton layer 202 can absorb the exudate from the patient's wound to keep the patient's wound dry.
[0029] A one-way water-permeable membrane layer 203 is arranged below the water-absorbing cotton layer 202, and the one-way water-permeable membrane layer 203 can make the exudate from the patient's wound flow unidirectionally, avoiding the situation of backflow.
[0030] The bottom surface of the water-absorbing cotton layer 202 is fixedly connected with a breathable layer 9, and the breathable layer 9 is fixedly connected with the one-way water-permeable membrane layer 203. Through the breathable layer 9, the breathability of the hemostatic bandage can be increased, thereby improving the comfort of the hemostatic bandage during use.
[0031] The bottom surface of the one-way water-permeable membrane layer 203 is fixedly connected with a medicament sustained-release layer 10. The inner wall of the medicament sustained-release layer 10 is provided with a medicament cavity for carrying hemostatic sustained-release and pain-relieving sustained-release agents. Through the medicament cavity opened on the medicament sustained-release layer 10, hemostatic and pain-relieving sustained-release agents can be added to the hemostatic bandage, enabling the continuous release of drugs after bandaging to promote the healing of the patient's wound.
[0032] Below the one-way water-permeable membrane layer 203, a hemostatic microsphere layer 204 is provided. A number of hemostatic microspheres provided below the hemostatic microsphere layer 204 are evenly adhered to the bottom surface of the hemostatic microsphere layer 204. The hemostatic microspheres evenly adhered to the bottom surface of the hemostatic microsphere layer 204 are used to adsorb the oozing blood at the wound of the patient, avoiding blood accumulation, and thus avoiding affecting the recovery of the patient's wound.
[0033] The bottom surface of the medicament sustained-release layer 10 is fixedly connected with an antibacterial layer 11. Through the antibacterial layer 11, the growth and reproduction of pathogenic microorganisms at the wound of the patient can be reduced, so as not to cause wound infection. The bottom surface of the antibacterial layer 11 is fixedly connected with a macroporous chitosan layer 12. The macroporous chitosan layer 12 is fixedly connected with the one-way water-permeable membrane layer 203. Through the macroporous chitosan layer 12, blood coagulation and thrombus formation can be promoted, and at the same time, it also has the advantages of inhibiting the growth of a variety of bacteria and promoting the repair of wound tissues.
[0034] The outer surface of the sealant layer 1 is fixedly connected with a first fixing band 3 and a second fixing band 4. One end of the second fixing band 4 far away from the sealant layer 1 is fixedly connected with a fixing frame 5. The inner wall of the fixing frame 5 is threadedly connected with a bolt 6. The outer surface of the bolt 6 is fixedly connected with a fixing plate 7.
[0035] The first fixing band 3 and the second fixing band 4 are respectively fixed on both sides of the sealant layer 1. The first fixing band 3 and the second fixing band 4 are both made of medical elastic non-woven fabric. The upper surface of the fixing plate 7 can be provided with sawteeth, so as to facilitate the fixing of the second fixing band 4.
[0036] By rotating the bolt 6, the fixing plate 7 can be driven to move up and down in the fixing frame 5, realizing the limit fixing of the second fixing band 4, so as to realize the adjustment of the tightness of the hemostatic bandage according to needs, ensure that the hemostatic bandage can closely fit the wound, and at the same time avoid blood circulation obstruction caused by being too tight.
[0037] The waterproof membrane layer 201, the absorbent cotton layer 202, the one-way water-permeable membrane layer 203 and the hemostatic microsphere layer 204 are layer structures of the same size and are adhered in sequence from top to bottom, enabling the hemostatic bandage to have good waterproof performance and hemostatic performance.
[0038] The components in the drawings of the present utility model are only for style reference and do not serve as specific dimension standards. The specific dimensions are determined according to the actual requirements of production.
[0039] Working principle: When using this waterproof traumatic hemostatic bandage, the sealing glue layer 1 on the outer surface of the waterproof film layer 201 enables the hemostatic bandage to have self-adhesion, which is convenient for the user to quickly bandage the patient's wound, and can also maintain sufficient adhesion underwater and is not easy to fall off. The waterproof film layer 201 can waterproof and seal the edge of the hemostatic bandage, enhancing the overall waterproof performance and preventing moisture from seeping in from the edge. The absorbent cotton layer 202 can absorb the exudate at the patient's wound to keep the patient's wound dry. The one-way water permeable film layer 203 enables the exudate at the patient's wound to flow unidirectionally, avoiding the situation of backflow. The hemostatic microsphere layer 204 evenly adhered to the bottom surface of the hemostatic microsphere layer 204 adsorbs the bleeding at the patient's wound, avoiding blood accumulation, and thus avoiding affecting the recovery of the patient's wound. Wind the first fixing band 3 and the second fixing band 4 around the patient's wound, and pass the second fixing band 4 through the fixing frame 5. Then rotate the bolt 6, which can drive the fixing plate 7 to move up and down in the fixing frame 5 to realize the limit fixation of the second fixing band 4, and the tightness of the hemostatic bandage can be adjusted as needed by adjusting the length of the second fixing band 4 passing through the fixing frame 5, ensuring that the hemostatic bandage can closely fit the wound while avoiding blood circulation obstruction caused by being too tight.
