Description

Technical Field

[0001] The invention relates to the field of medical bandage fixation, and in particular to an auxiliary flexible patch for preventing a bandage from loosening. Background Art

[0002] Medical polymer splints and ordinary plaster can both be used for external fixation of orthopedic fractures or orthopedic parts. Polymer splints are high in hardness and light in weight, which reduces the load on functional exercises after fixation, is beneficial to blood circulation, and promotes healing. Therefore, medical polymer splints are increasingly used in clinical practice.

[0003] There is a shortcoming of medical polymer splints during use by patients: since the outer lining surface is relatively smooth, it is easy to loosen and slide down after being tightened with medical gauze bandages, losing the proper tightening effect. Especially when the medical polymer splint is fixed through the thigh section from the knee joint to the thigh root and the upper arm section from the elbow joint to the shoulder, it must be bandaged obliquely (or spirally folded) from the distal end to the proximal end. Since the winding diameter changes from small to large, it is very easy to loosen and slide down when the patient is standing.

[0004] At present, there is no good way to fix medical polymer splints (or ordinary plaster). Once the medical bandage loosens and slides down, it can only be re-wound and fixed. Generally, it needs to be re-fixed once every one to two days. The fixation time of medical polymer splints (or ordinary plaster) is generally one to two months or even longer. Therefore, frequent wrapping and fixation is troublesome. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an auxiliary flexible patch for preventing bandages from loosening, which can avoid patients from frequently changing and fixing medical bandages.

[0006] According to an embodiment of the present invention, an auxiliary flexible patch for preventing a bandage from loosening comprises: an inner adhesive layer, a base layer, and an outer adhesive layer which are sequentially stacked and fixedly connected, the inner adhesive layer being used to be adhered to the outer surface of an object to be fixed, the outer adhesive layer being used to be adhered to the inner surface of a bandage, and a plurality of water-curable fiber baffles being spaced apart on the outer adhesive layer.

[0007] The auxiliary flexible patch for preventing bandages from loosening according to the embodiment of the present invention has at least the following technical effects: the auxiliary flexible patch is pasted on the outer lining cloth of the medical polymer splint or ordinary plaster through the inner adhesive layer, and then the medical bandage is wrapped around the outer adhesive layer, and the inner surface of the main medical bandage is pasted through the outer adhesive layer, so that the medical bandage can be adhered and fixed to prevent it from loosening; in addition, the water-curable fiber baffle that solidifies after being soaked in water can further prevent the medical bandage from loosening and sliding down. It saves patients from the trouble of frequently changing and fixing medical bandages, and can also make the patient's injured part more firmly fixed by the medical polymer splint for a longer time, thereby achieving better treatment effects.

[0008] According to some embodiments of the present invention, one or more air holes are provided on the base layer.

If there is a description of the first or the second, it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0020] refer to Figure 1 , an auxiliary flexible patch for preventing a bandage from loosening, comprising: an inner adhesive layer 100, a base layer 200, and an outer adhesive layer 300 which are sequentially stacked and fixedly connected, the back side of the inner adhesive layer 100 is fixed to the surface of the base layer 200 by glue, and the other side is used to be pasted to the outer surface of the object to be fixed, and the back side of the outer adhesive layer 300 is fixed to the base layer 200 by glue for pasting the inner surface of the bandage. Preferably, in this embodiment, both the inner adhesive layer 100 and the outer adhesive layer 300 are made of nylon Velcro, which can be firmly adhered to the outer lining layer of the surface of the medical polymer splint and the inner side of the bandage, and can also use matching adhesive materials according to different surface materials of the object to be fixed; the base layer 200 is made of a medical plastic base sheet, and can also use other conventional light and bendable bases.

[0021] In order to better fix the bandage, a plurality of water-curable fiber baffles 400 are arranged at intervals on the outer adhesive layer 300. Preferably, the protruding length of the water-curable fiber baffles 400 is 0.2-1 cm, and the distance between each water-curable fiber baffle 400 is 2-10 cm.

[0022] refer to Figure 2In order to enhance the air permeability, a plurality of air holes 210 are provided on the base layer 200. The number of the air holes 210 can be determined according to different specifications. If the inner adhesive layer 100 and the outer adhesive layer 300 are made of an adhesive material with good air permeability such as nylon hook and loop tape, through holes may not be provided at the corresponding positions of the air holes 210. If other adhesive materials with poor air permeability are used, corresponding through holes need to be provided at the corresponding positions of the air holes 210. The auxiliary flexible patch can be manufactured into single-piece products of different sizes, each piece is packaged independently. It can also be manufactured into a cuttable roll product. The size of the auxiliary flexible patch of the embodiment of the present invention is determined according to the width of the medical polymer splint used, and the width is 2 cm to 5 cm smaller than the width of the polymer splint; the length is about 5 cm smaller than the length from the knee joint (or elbow joint) to the proximal end of the medical polymer splint. The auxiliary flexible patch can be cut according to the actual bandaging situation.

[0023] Taking the auxiliary flexible patch with nylon hook and loop fastener and the medical polymer splint as examples, the use process of the embodiment of the present invention is as follows:

[0024] Tear off the velvet surface of the nylon hook and loop tape on both sides of the auxiliary flexible patch, and spray a little medical pure water on the water-curable fiber baffle 400. The auxiliary flexible patch is used in conjunction with the medical polymer splint 500. First, the medical staff uses the medical polymer splint 500 to fix the injured part of the patient that needs to be fixed. After the medical staff uses the medical bandage to bandage across the knee joint (or elbow joint) from the distal end to the proximal end in an oblique shape (or spiral fold), the hook surface of the nylon hook and loop tape on the inner surface of the auxiliary flexible patch is attached to the outer lining layer 510 of the medical polymer splint 500, and then the bandage is continued to the proximal end of the medical polymer splint 500. When bandaging this section of the auxiliary flexible patch, firstly, the hook surface of the nylon hook and loop tape on the outer surface of the medical auxiliary flexible patch is wrapped inside the medical bandage, which can adhere and fix the medical bandage to prevent it from loosening. Then, the water-curable fiber baffle 400 on the outer surface of the auxiliary flexible patch is stood up (or slightly tilted toward the proximal end). After the bandaging is completed, wait for a while until the water-curable fiber baffle 400 absorbs water and solidifies, so as to prevent the medical bandage from loosening and sliding down.

[0025] The method of using the present invention in combination with ordinary gypsum is the same as that of the medical polymer splint 500.

[0026] In summary, the embodiment of the present invention saves patients from the trouble of frequently changing and fixing medical bandages, and also enables the injured part of the patient to be fixed more firmly and durably by the medical polymer splint 500, thereby achieving better treatment effects.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
