Description

Technical Field

[0001] The utility model relates to the technical field of medical dressings, in particular to a medical dressing with a waterproof function. Background Technique

[0002] A medical dressing is a medical product similar to a wound dressing, which can be used for debridement and dressing of different wounds, facilitating wound healing. It mainly uses a water-soluble polymer material as the matrix skeleton, contains 60% water, and achieves a cold compress treatment effect through the physical action of active ingredients such as menthol contained in it and the hydrogel.

[0003] For example, a medical dressing with a waterproof function (Publication No.: CN217448232U), which includes a dressing main body, a waterproof mechanism and an easy-to-tear mechanism. The dressing main body consists of a dressing, a non-woven fabric, a first adhesive layer and a release film. The waterproof mechanism is composed of a waterproof cloth, which is arranged at the top of the dressing main body. A first connection mechanism is arranged between the waterproof cloth and the dressing main body. The easy-to-tear mechanism is composed of a connecting paper, which is fixedly connected to one side of the release film. A second connection mechanism is arranged between the connecting paper and the waterproof cloth. A separation mechanism is arranged on the outer wall of the connecting paper. This utility model makes use of the setting of the waterproof cloth and, with the cooperation of the first connection mechanism, makes the waterproof cloth stick to the top of the non-woven fabric for use, effectively avoiding the phenomenon that the dressing cannot be used when it comes into contact with water during use, and improving the waterproof effect of the dressing.

[0004] When this device is in use, it can only be waterproofed by the waterproof cloth. However, when the dressing is in use, as the patient moves, the glue at its corners becomes less sticky, resulting in the situation of warping. In this way, water easily enters the wound, affecting the recovery of the wound. Therefore, we need to propose a medical dressing with a waterproof function. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A medical dressing with a waterproof function includes a base layer 1. A first waterproof layer 2 is provided on the top of the base layer 1. A dressing 3 is provided at the center of the bottom of the base layer 1. A waterproof component 4 for waterproofing is provided at the bottom of the base layer 1. A paste layer 5 is further provided at the bottom of the base layer 1. A release paper 6 is adhered to the bottom of the paste layer 5. The waterproof component 4 includes a second waterproof layer 41, and the second waterproof layer 41 is bonded to the bottom of the base layer 1. An anti-seepage layer 42 is provided inside the second waterproof layer 41. An absorbent layer 43 is provided inside the anti-seepage layer 42. The top of the dressing is waterproofed by the first waterproof layer 2. By providing the waterproof component 4, the water seeping in from its curled edge can be blocked and absorbed, further improving the waterproof effect, preventing water from entering the wound, and ensuring the recovery of the wound. It should be noted that the paste layer 5 is an adhesive for bonding the dressing to the skin, and the paste layer 5 is located at all places at the bottom of the base layer 1 except the dressing 3 and the waterproof component 4;

[0024] The waterproof component 4 is arranged in an "O" shape, and the dressing 3 is located inside the waterproof component 4, which can block and absorb external water sources in all directions to ensure that no water enters the dressing 3;

[0025] The base layer 1 includes a skin-friendly layer 11, a breathable layer 12, and an antibacterial layer 13. The breathable layer 12 is located on the top of the skin-friendly layer 11, and the antibacterial layer 13 is located on the top of the breathable layer 12. The skin-friendly layer 11 improves the user experience of the patient and can avoid the situation of redness, swelling, and itching of some patients. The breathable layer 12 can better keep the wound of the patient dry and promote the better recovery of the patient's wound. The antibacterial layer 13 can better sterilize external bacteria and reduce the possibility of wound infection;

[0026] The first waterproof layer 2 is located on the top of the antibacterial layer 13. The first waterproof layer 2 waterproofs the top of the dressing. The dressing 3, the waterproof component 4, and the paste layer 5 are all located at the bottom of the skin-friendly layer 11. After the paste layer 5 is bonded to the skin, there is a curled edge at its corner. The waterproof component 4 blocks and absorbs the water seeping in from its curled edge to prevent water from entering the dressing 3 and the wound;

[0027] The release paper 6 is adhered to the bottom of the base layer 1 through the adhesive layer 5, and both the waterproof component 4 and the dressing 3 are located above the release paper 6. The release paper 6 exists before the patch is used, mainly to ensure the adhesiveness of the adhesive layer 5 and the quality of the dressing 3;

[0028] The size of the release paper 6 is adapted to the size of the base layer 1. One end of the release paper 6 is fixedly connected with an easy-to-tear block 7. The release paper 6 just covers the bottom of the base layer 1. By providing the easy-to-tear block 7, it is convenient for the patient to tear off the release paper 6 during use;

[0029] Working principle: When the utility model is used, first tear off the release paper 6 through the easy-to-tear block 7, then align the dressing 3 with the wound, and then use the adhesive layer 5 to stick the dressing on the patient's skin. The top of the patch can be waterproofed through the first waterproof layer 2. Through the provided waterproof component 4, the water seeping in from the curled edge can be blocked and absorbed, further improving the waterproof effect, preventing water from entering the wound, and ensuring the recovery of the wound.
