Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an anti-loosening structure for bandages. Background Technology

[0002] Bandages are gauze strips used to wrap wounds or affected areas. They are common medical supplies with many different types and methods of application. The appropriate type and method must be selected based on the location of the injury. When wrapping a bandage, the caregiver needs to hold one end of the bandage with one hand and pull it taut with the other, wrapping it around the area to be bandaged. This is inconvenient. Because bandages have a certain degree of elasticity, they tend to shrink back over time and with patient movement after application, causing them to loosen and hindering wound healing.

[0003] Chinese Utility Model Patent Publication No. CN 221286089 U discloses a hemostatic bandage. This bandage, through the arrangement of adhesive layers, allows the ends of the bandage to adhere to the human body, facilitating operation by medical personnel. Furthermore, the spaced adhesive layers connect with the bandage body, providing phased fixation points to reduce the bandage's rebound and prevent loosening after application. However, while this hemostatic bandage reduces rebound, it lacks a multi-directional fixation structure. This necessitates secondary fixation with a medical bandage and makes the bandage prone to detachment after application, thus affecting its normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an anti-loosening structure for bandages. It can effectively solve the problem that although the existing technology can reduce the rebound of the bandage, it does not have a multi-directional fixing structure. Not only does it require the use of medical bandages for secondary fixing, but it is also easy for the bandage to fall off after it is pasted, thus affecting its normal use.

[0005] The technical solution adopted by this utility model is: a bandage anti-loosening structure, including a bandage body, a breathable component provided on the inner surface of the bandage body, a first adhesive surface with a "U" shaped cross-section for initial adhesive application at one end of the bandage body away from the center line, a second adhesive surface with a "U" shaped cross-section for final adhesive application at the other end of the bandage body away from the first adhesive surface, a plurality of equally spaced extension strips provided at the other end of the bandage body near the second adhesive surface, and adhesive wings folded at the other two ends of the bandage body away from the first and second adhesive surfaces.

[0006] Preferably, one end of the extension strip is provided with an adhesive surface, and the other end of the adhesive surface away from the extension strip is provided with release paper, and the extension strip, the adhesive surface and the release paper are in one-to-one correspondence.

[0007] Through the above technical solution, by combining the extension strip, the adhesive surface and the release paper, after the bandage is wrapped, the release paper on the surface of the adhesive surface can be torn off, and then the adhesive surface can come into contact with the skin surface of the patient's affected limb, which can play a secondary fixation role and prevent it from falling off from the end, thus affecting normal use.

[0008] Preferably, the adhesive surface and the release paper are provided with multiple identical strips, and the multiple adhesive surfaces and the release paper are distributed at equal intervals about one side of the bandage body.

[0009] Through the above technical solution, and the design of multiple adhesive surfaces and release paper, the contact area can be further increased when the whole is pasted onto the skin surface. Moreover, the multiple adhesive surfaces do not interfere with each other, thereby avoiding the loss of adhesion of a single adhesive surface from affecting the normal use of other adhesive surfaces.

[0010] Preferably, the breathable component includes a non-woven fabric, with a breathable layer at one end of the non-woven fabric near the center line of the bandage body, and a skin-friendly layer at the other end of the breathable layer away from the non-woven fabric. The cross-sections of the non-woven fabric and the skin-friendly layer are arranged in a crisscross pattern, and the cross-sections of the breathable layer are arranged in an "X" shape.

[0011] The above technical solution enhances the resistance to deformation by using a cross-sectional arrangement of non-woven fabric and skin-friendly layer. In addition, the breathable layer with an "X"-shaped structure further improves the resistance to deformation, preventing the bandage from breaking or deforming during use, which could lead to a decrease in adhesion.

[0012] Preferably, the nonwoven fabric is a polypropylene nonwoven fabric, the breathable layer is a polyethylene breathable membrane, and the skin-friendly layer is made of polyester fiber material.

[0013] Through the above technical solution, the non-woven fabric made of polypropylene has strong water repellency, which can prevent external moisture, dust and other pollutants from entering the inside of the bandage. At the same time, it is soft and has little skin irritation. In addition, the polyethylene breathable membrane can further improve its breathability. Combined with polyester fiber, which has good moisture absorption, it can quickly absorb sweat and exudate on the skin surface, keep the skin dry, and has good skin affinity, will not cause friction damage, and helps wound healing.

[0014] Preferably, the two ends of the adhesive wing near the first adhesive surface and the second adhesive surface are designed with chamfers, and the adhesive surface of the adhesive wing is covered with release paper.

[0015] With the above technical solution, after the first adhesive surface, the second adhesive surface, and the bonding surface are pasted, the folded adhesive wings can be put down, and then the release paper can be torn off, so that the adhesive wings come into contact with the skin, which can further increase the adhesive area, prevent the bandage from easily loosening, and fix needles and other items to the adhesive wings, thereby reducing the use of medical tape.

[0016] Preferably, there are two identical adhesive wings and release paper, and the two adhesive wings and release paper are symmetrically distributed about the center line of the bandage body.

[0017] By using the above technical solution and the design of two identical adhesive wings and release paper, the bandage can be fixed from two directions, which can further improve its anti-loosening ability and improve its practicality.

[0018] Compared with the prior art, this utility model provides an anti-loosening structure for bandages, which has the following characteristics:

[0019] Beneficial effects:

Through the cooperation of the extension strip, adhesive surface and release paper, after the bandage is wrapped, the release paper on the adhesive surface can be torn off, and then the adhesive surface can come into contact with the skin surface of the patient's affected limb, which can play a secondary fixation role and prevent it from falling off from the end, thus affecting normal use.

[0021] 2. The bandage has an anti-loosening structure. After the first adhesive surface, the second adhesive surface, and the bonding surface are pasted, the folded adhesive wings can be put down, and then the release paper can be torn off to allow the adhesive wings to come into contact with the skin, which can further increase the adhesive area and prevent the bandage from easily loosening. It can also fix needles and other items to the adhesive wings, which can reduce the use of medical tape.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: As Figure 1-7 As shown, the present invention provides an anti-loosening structure for bandages, including a bandage body 1, a breathable component 2 on the inner surface of the bandage body 1, a first adhesive surface 3 with a "U" shaped cross-section for initial adhesive application at one end of the bandage body 1 away from the center line, a second adhesive surface 4 with a "U" shaped cross-section for final adhesive application at the other end of the bandage body 1 away from the first adhesive surface 3, a plurality of equally spaced extension strips 5 at the other end of the bandage body 1 near the second adhesive surface 4, and adhesive wings 8 folded at the other two ends of the bandage body 1 away from the first adhesive surface 3 and the second adhesive surface 4.

[0033] Specifically, one end of the extension strip 5 is provided with an adhesive surface 6, and the other end of the adhesive surface 6 away from the extension strip 5 is provided with release paper 7. The extension strip 5, the adhesive surface 6, and the release paper 7 are in one-to-one correspondence. The advantage is that, through the cooperation of the extension strip 5, the adhesive surface 6, and the release paper 7, after the bandage is wrapped, the release paper 7 on the surface of the adhesive surface 6 can be torn off, and then the adhesive surface 6 can come into contact with the skin surface of the patient's affected limb, which can play a secondary fixation role and prevent it from falling off from the end, thus affecting normal use.

[0034] Specifically, the adhesive surface 6 and the release paper 7 are provided with multiple identical strips. The multiple adhesive surfaces 6 and the release paper 7 are distributed at equal intervals on one side of the bandage body 1. The advantage is that, through the design of multiple adhesive surfaces 6 and release paper 7, when the whole is pasted onto the skin surface, its contact area can be further increased, and the multiple adhesive surfaces 6 do not interfere with each other, thereby avoiding the loss of adhesiveness of a single adhesive surface 6, which would affect the normal use of other adhesive surfaces 6.

[0035] Specifically, the breathable component 2 includes a non-woven fabric 201. A breathable layer 202 is provided at one end of the non-woven fabric 201 near the center line of the bandage body 1, and a skin-friendly layer 203 is provided at the other end of the breathable layer 202 away from the non-woven fabric 201. The cross-sections of the non-woven fabric 201 and the skin-friendly layer 203 are arranged in a crisscross pattern, and the cross-section of the breathable layer 202 is arranged in an "X" shape. The advantage is that the crisscross pattern of the cross-sections of the non-woven fabric 201 and the skin-friendly layer 203 can enhance its resistance to deformation. At the same time, the "X" shaped structure of the breathable layer 202 can further improve its resistance to deformation, preventing the bandage from easily breaking or deforming during use, which would lead to a decrease in adhesion.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, non-woven fabric 201 is made of polypropylene non-woven fabric, breathable layer 202 is made of polyethylene breathable membrane, and skin-friendly layer 203 is made of polyester fiber material. The advantages are that the non-woven fabric 201 made of polypropylene has strong water repellency, which can prevent external moisture, dust and other pollutants from entering the inside of the bandage. At the same time, it is soft and has little skin irritation. In addition, the polyethylene breathable membrane can further improve its breathability. Combined with polyester fiber, which has good moisture absorption, it can quickly absorb sweat and exudate on the skin surface, keep the skin dry, and has good skin affinity, will not cause friction damage, and helps wound healing.

[0038] Specifically, the two ends of the adhesive wing 8 near the first adhesive surface 3 and the second adhesive surface 4 are designed with chamfers. The adhesive surface of the adhesive wing 8 is covered with release paper 9. The advantage is that after the first adhesive surface 3, the second adhesive surface 4 and the adhesive surface 6 are pasted, the folded adhesive wing 8 can be put down and then the release paper 9 can be torn off, so that the adhesive wing 8 can come into contact with the skin, which can further increase its adhesive area, prevent the bandage from easily loosening, and can also fix needles and other items to the adhesive wing 8, which can reduce the use of medical tape.

[0039] Specifically, there are two identical adhesive wings 8 and release paper 2 9. The two adhesive wings 8 and release paper 2 9 are symmetrically distributed about the center line of the bandage body 1. The advantage is that by using the design of two identical adhesive wings 8 and release paper 2 9, the bandage can be fixed from two directions, which can further improve its anti-loosening ability and improve its practicality.

[0040] Working principle: In use, firstly, the first adhesive surface 3 is attached to the skin surface. Then, the bandage body 1 is wrapped around the affected limb once. Next, the second adhesive surface 4 is attached to the skin end. Through the cooperation of the extension strip 5, the adhesive surface 6, and the release paper 7, after the bandage is wrapped, the release paper 7 on the surface of the adhesive surface 6 can be peeled off, allowing the adhesive surface 6 to come into contact with the skin surface of the patient's affected limb. This provides secondary fixation, preventing it from falling off from the end and affecting normal use. Multiple adhesive strips... The design of the adhesive surface 6 and release paper 7 further increases the contact area when the entire bandage is adhered to the skin surface. Furthermore, the multiple adhesive surfaces 6 do not interfere with each other, thus preventing the loss of adhesion from a single adhesive surface 6 from affecting the normal use of other adhesive surfaces 6. The cross-sectional distribution of the non-woven fabric 201 and the skin-friendly layer 203 enhances its resistance to deformation. Simultaneously, the addition of the breathable "X"-shaped structure of the breathable layer 202 further improves its resistance to deformation, preventing the bandage from easily breaking or deteriorating during use. Deformation leads to decreased adhesion. The non-woven fabric 201 made of polypropylene has strong water repellency, preventing external moisture, dust, and other contaminants from entering the bandage. It is also soft and has low skin irritation. The polyethylene breathable membrane further improves its breathability. Combined with polyester fiber, which has good moisture absorption, it can quickly absorb sweat and exudate from the skin surface, keeping the skin dry. It is also skin-friendly and will not cause friction damage, which helps wound healing. After the first adhesive surface 3, the second adhesive surface 4, and the adhesive surface 6 are attached, the folded adhesive wings 8 can be put down, and then the release paper 29 can be torn off, so that the adhesive wings 8 come into contact with the skin, which can further increase its adhesive area and prevent the bandage from loosening easily. It can also fix needles and other items to the adhesive wings 8, reducing the use of medical tape. The design of two adhesive wings 8 and release paper 29 can fix the bandage from two directions, which can further improve its anti-loosening ability and improve its practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
