Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a cotton adhesive waterproof film. Background Art
[0002] During limb surgery, pressure tourniquets are sometimes used to apply pressure during surgery to reduce bleeding, depending on the surgical requirements. When using a pressure tourniquet, the pressure parameters are adjusted according to the patient's basic blood pressure. Due to the application of pressure, in the prior art, the tourniquet directly contacts the patient's skin, which can easily lead to the formation of blisters and pressure sores on the skin. During the preoperative disinfection process, the disinfectant can easily soak the pressure tourniquet. Long-term soaking of the tourniquet can cause damage to the tourniquet and easily cause iodine burns on the patient's skin. Summary of the invention
[0003] The purpose of the present invention is to provide a cotton sticky waterproof film, aiming to solve the problem in the prior art that the tourniquet directly contacts the patient's skin, which easily leads to the formation of blisters and pressure sores on the skin; during the preoperative disinfection process, the disinfectant easily soaks the pressure tourniquet, and soaking the tourniquet for a long time will cause the tourniquet to be damaged and easily cause iodine burns on the patient's skin.
[0004] The present invention is implemented in this way: a cotton sticky waterproof film, the cotton sticky waterproof film includes an adhesive part and a skin-friendly part, the adhesive part is fixedly connected to the skin-friendly part, the adhesive part is coated with an adhesive layer, and the adhesive layer is used to bond with the skin-friendly part.
[0005] Preferably, both the adhesive portion and the skin-friendly portion are provided with breaking strips, and the breaking strips are used to cut off the adhesive portion and the skin-friendly portion.
[0006] Preferably, a film is attached to the adhesive layer.
[0007] Preferably, the skin-friendly portion is made of cotton material.
[0008] Preferably, the thickness of the skin-friendly portion is between 0.19-0.21 cm.
[0009] Preferably, the thickness of the skin-friendly portion is 0.2 cm.
[0010] Preferably, the total width of the adhesive portion and the skin-friendly portion is greater than twice the width of the tourniquet.
[0011] The cotton sticky waterproof film provided by the present invention has a simple structure and can prevent the pressure tourniquet from directly contacting the patient's skin during surgery to cause blisters or pressure sores. The film can be provided to prevent the tourniquet from being soaked by disinfectant or other liquids, making operation more convenient and time-saving. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 A schematic structural diagram of a cotton adhesive waterproof membrane provided in an embodiment of the present invention.
[0013] In the attached figure: 1, adhesive part; 2, breaking zone; 3, skin-friendly part; 4, film. DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0016] like Figure 1 As shown, it is a structural schematic diagram of a cotton sticky waterproof film provided by an embodiment of the present invention, wherein the cotton sticky waterproof film includes an adhesive portion 1 and a skin-friendly portion 3, wherein the adhesive portion 1 is fixedly connected to the skin-friendly portion 3, and an adhesive layer is coated on the adhesive portion 1, and the adhesive layer is used to bond with the skin-friendly portion 3.
[0017] In an embodiment of the present invention, an adhesive layer is arranged on a single side of the adhesive portion 1, and the side provided with the adhesive layer is defined as the back side, and the other side is defined as the front side. The front side is made of cotton material. When in use, the front side is directly in contact with the patient's skin, and the adhesive portion 1 is close to the distal end of the user. The tourniquet is then fixed on this waterproof film. The cotton sticky waterproof film is used to isolate the tourniquet and the user's skin. After the tourniquet is fixed, the adhesive portion 1 is folded up, so that the entire tourniquet is wrapped by the adhesive portion 1 and the skin-friendly portion 3, and the adhesive portion 1 is fixed to the skin-friendly portion 3 by the adhesive layer. At this time, the cotton material is in contact with the user, and the adhesive portion 1 can play a waterproof role. A film 4 is attached to the adhesive layer. The film 4 is arranged to avoid adhesion when not in use. The skin-friendly portion 3 is made of cotton material to avoid direct contact with the patient's skin when the pressure tourniquet is used during surgery to cause blisters or pressure sores. The thickness of the skin-friendly portion 3 is between 0.19-0.21cm, and preferably, 0.2cm is used.
[0018] In this embodiment, in order to adapt to different patients, the adhesive part 1 and the skin-friendly part 3 can be of different sizes for easy adaptation; a breaking strip can also be provided on the adhesive part 1 and the skin-friendly part 3, and the adhesive part 1 and the skin-friendly part 3 can be cut according to the limb sizes of different patients to obtain a suitable length. Alternatively, no breaking strip is provided, and the device can be cut as needed.
[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
