[0002] A dressing, that is, a plaster product, uses a non-woven material. The traditional Chinese medicine paste is applied on the non-woven fabric and pasted on the affected part of the patient. Through the absorption of the skin, the medicinal effect is exerted to relieve the pain of the patient.
[0003] In the traditional technology, a protective film of the same size as the dressing is independently arranged on one side of the adhesive layer of the dressing to prevent the adhesive layer and the medicament layer of the dressing from contacting dust, prevent the medicament layer from being infected by the outside world and the adhesion ability of the adhesive layer from decreasing. This operation is convenient and fast. However, in actual use, the adhesive layer and the protective film are closely attached, and both hands are needed to rub the dressing open, so that there is a gap between the adhesive layer and the protective film. Then, the protective film is buckled by fingers, and finally the protective film and the adhesive layer are separated. When both hands rub the dressing open, the adhesive layers will adsorb to each other, resulting in the dressing being in a wrinkled state.
[0004] Therefore, for the improvement of the existing disposable dressing with good liquid absorption and easy tearing, it is particularly important to design a new disposable dressing with good liquid absorption and easy tearing to solve the above technical defects and improve the overall practicability of the disposable dressing with good liquid absorption and easy tearing.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.
[0021] Embodiment:
[0022] Please refer to Figures 1 - 3 , the present invention provides a technical solution:
[0023] A disposable dressing with good liquid absorption and easy tearing, including an adhesive tape 1. Cuts 2 are provided at the four corners of the outside of the adhesive tape 1. Barrier tapes 3 are symmetrically adhesively connected to the top of the adhesive tape 1. Arc-shaped blocks 4 and arc-shaped grooves 5 are respectively provided at positions where the barrier tapes 3 are close to each other. Tear tapes 6 are fixedly connected to the ends of the arc-shaped blocks 4 away from each other. A medicated cotton 7 is provided in the middle of the adhesive tape 1. A limit frame 701 is fixedly connected to the outside of the medicated cotton 7. When a patient has a pain, an operator gently pinches the tear tape 6 and moves in the direction opposite to the tear tape 6, thereby driving the arc-shaped block 4 to tilt up, and driving the barrier tape 3 to tilt up accordingly, so that half of the medicated cotton 7 is exposed. The medicated cotton 7 is attached to the pain area of the patient, and the other group of tear tapes 6 is torn off, so that both groups of barrier tapes 3 are separated from the adhesive tape 1, and the adhesive tape 1 is gently patted to make the adhesive tape 1 tightly adhere to the skin. The medicine inside the medicated cotton 7 penetrates into the human body through the skin, thereby accelerating the healing of the painful area.
[0024] Further, please refer to Figure 1 , Figure 2 and Figure 3, in this embodiment, guide grooves 8 are provided on both the left and right sides of the tape 1. A secondary tape 9 is fixedly connected inside the guide groove 8. The secondary tape 9 is designed in a triangular structure. The secondary tape 9 and the tape 1 are pasted together by sterile cotton threads. When the wrist or elbow needs to be treated with the tape 1, the operator's hands respectively pinch the tape 1 and the secondary tape 9 and pull them in opposite directions, causing the sterile cotton threads to break, so as to separate the secondary tape 9 from the tape 1 and expose the guide groove 8. The elbow is cross-fixed through the guide groove 8, so that the guide groove 8 presents an X-shaped structure design, and the elbow is placed between the X-shaped guide grooves 8, so as to ensure that when the joint rotates, it will not be blocked by the tape 1 and the flexible movement of the hand cannot be guaranteed.
[0025] Further, please refer to Figure 2 , in this embodiment, a PU film 10 is adhesively connected between the barrier tape 3 and the tape 1. The top of the tape 1 is coated with medical glue. The PU film 10 is adhesively connected to the top of the tape 1 through the medical glue. Through the design of the PU film 10, it plays a role in waterproofing. At the same time, the medical glue can prevent secondary infection at the wound, and the skin at the joint has no tight feeling and will not wrinkle.
[0026] Further, please refer to Figure 2 and Figure 3 , in this embodiment, the medicated cotton 7 is designed in a mesh structure. The top of the medicated cotton 7 is coated with a silica gel pad, and the silica gel pad is also designed in a mesh structure. The medicated cotton 7 is fixed inside it through the limit frame 701. When the tape 1 contacts the human body and the human body turns over or moves, the medicated cotton 7 will not shift and always fits with the patient's wound, which is beneficial to accelerating the recovery and healing of the wound. The silica gel pad designed in a mesh hole structure improves the air permeability and comfort of the product. At the same time, the addition of the silica gel pad can also better adhere to the skin and increase the stability of the patch.
[0027] Further, please refer to Figure 2 and Figure 3 , in this embodiment, convex strips 11 are symmetrically and fixedly connected to the outside of the limit frame 701. The convex strips 11 are soft rubber convex strips. Adhesive tapes 12 are fixedly connected to the four corners at the top of the tape 1. A protective film 13 is adhesively connected to the top of the adhesive tape 12. By tearing off the protective film 13 to expose the adhesive tape 12, the adhesive tape 12 is attached to the human body, and at the same time, another group of adhesive tapes 12 is attached to the surface of the tape 1 to make the guide groove 8 in an X shape. By contacting the skin with the convex strips 11, there is a gap between the medicated cotton 7 and the human body, so that the skin is in a dry state and will not cause the painful area to turn white and develop prickly heat due to hot weather.
[0028] Further, please refer to Figure 3, in this embodiment, the tape 1 is composed of a protective layer 101 and an absorption layer 102. The protective layer 101 is disposed on the top of the tape 1, and the absorption layer 102 is disposed at the bottom of the protective layer 101. Ventilation holes are formed inside the protective layer 101 and are equally spaced. Through the ventilation holes in the protective layer 101, the air permeability of the skin around the wound is improved, skin whitening is avoided, and wound healing is promoted.
[0029] Further, please refer to Figure 3 , in this embodiment, the absorption layer 102 is made of SAF non-woven fabric. A round groove 103 is formed inside the absorption layer 102, and an expansion ball 104 is fixedly connected inside the round groove 103. The SAF non-woven fabric with high liquid absorption capacity has a strong liquid absorption capacity. After the absorption material absorbs liquids such as blood, it will turn into a gel state, avoiding the extrusion of the liquid after external pressure, so as to keep the wound dry and reduce the risk of infection. At the same time, when the external liquid contacts the absorption layer 102, the expansion ball 104 expands rapidly when encountering water, blocking the round groove 103 to prevent external liquid from entering the inner layer and causing external infection.
[0030] In this embodiment, the implementation scenario is as follows: When a patient has a pain or injury, the operator gently pinches the tear strip 6 and moves it in the direction opposite to the tear strip 6, thereby driving the arc-shaped block 4 to tilt up, and driving the barrier strip 3 to tilt up accordingly, so that half of the medicated cotton 7 is exposed. Then, the medicated cotton 7 is attached to the pain or injury of the patient, and the other group of tear strips 6 is torn open, so that both groups of barrier strips 3 are separated from the adhesive tape 1. By gently patting the adhesive tape 1, the adhesive tape 1 is tightly attached to the skin. The medicated cotton 7 is fixed inside through the limit frame 701. When the adhesive tape 1 contacts the human body and the human body turns over or moves, the medicated cotton 7 will not shift and always fits with the patient's wound, which is beneficial to accelerating the recovery and healing of the wound. The silicone pad is designed as a mesh structure to improve the air permeability and comfort of the product. At the same time, the addition of the silicone pad can better adhere to the skin and increase the stability of the patch. When the adhesive tape 1 is needed for treatment at the wrist or elbow, the operator's hands respectively pinch the adhesive tape 1 and the auxiliary tape 9 and pull them in opposite directions, causing the sterile cotton thread to break, so that the auxiliary tape 9 is separated from the adhesive tape 1, and the guide groove 8 is exposed. The elbow is cross-fixed through the guide groove 8. By tearing off the protective film 13, the adhesive tape 12 is exposed, and the adhesive tape 12 is attached to the human body. At the same time, the other group of adhesive tapes 12 is attached to the surface of the adhesive tape 1, so that the guide groove 8 presents an X-shaped structure design, and the elbow is placed between the X-shaped guide grooves 8, so that when the joint rotates, it will not be blocked by the adhesive tape 1 and the flexible movement of the hand cannot be guaranteed. The air permeability of the skin around the wound is improved through the air holes in the protective layer 101, avoiding skin whitening and promoting wound healing. The SAF non-woven fabric with high liquid absorption capacity has a strong liquid absorption capacity. After the absorbent material absorbs liquids such as blood, it will become gel-like, preventing the liquid from being squeezed out after external pressure, thereby keeping the wound dry and reducing the risk of infection. At the same time, when the external liquid contacts the absorbent layer 102, the expansion ball 104 expands rapidly when encountering water, blocking the round groove 103 and preventing external liquid from entering the inner layer and causing external infection.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
