Description

Technical Field

[0001] This utility model relates to the field of sports protective tape technology, specifically an H-shaped finger sports protective tape. Background Technology

[0002] Sports protective tape is a protective product specifically designed for sports activities. Made from elastic fabric or non-woven material coated with medical-grade pressure-sensitive adhesive, it combines stickiness and breathability. By taping it onto joints, it provides support, restricts excessive movement to prevent sprains and strains, reduces muscle tremors, and improves movement stability. Available in stabilizing and recovery types, some contain hypoallergenic ingredients to suit sensitive skin and adapt to limb flexion and extension during exercise. Widely used in sports such as basketball, running, and dance, it aids in the recovery of injured areas and serves as a daily sports protection tool, making it a common piece of equipment for athletes and fitness enthusiasts.

[0003] In sports such as rock climbing, tennis, and fitness, the skin on the inside of the finger joints is easily damaged by friction, and the tendon trochlear system also requires additional support to avoid injury. Existing protective tapes have the following drawbacks: Straight tapes require crisscrossing to form an "X" shape for fixation, which is complex and time-consuming, requiring an average of 3-5 turns of crisscrossing. The thickness increases at the overlap, affecting fine finger movements and relying on skillful operation. If the operation is not precise, tape still covers the outside of the joint, limiting the flexion angle by about 15%-20%. Multiple layers make it difficult for breathability and sweat to penetrate, and it is easy to delaminate and fall off after being soaked in sweat, with a fixation strength reduction of ≥40%. In addition, H-shaped fixation tapes for large joints, such as elbow and knee joint protection products, are not suitable for finger joints with a central base width >5cm and branch width >2cm. The size far exceeds the standard finger joint anatomy, as the average finger joint width is only 1.5-2cm. Branched adhesive tape covers the extensor tendon of the dorsiflexor muscles, hindering the tendon's sliding mechanism.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing sports protective tape. Utility Model Content

[0006] The purpose of this invention is to provide an H-shaped finger movement protective tape to solve the problems mentioned in the background art, such as the inability to accurately apply pressure to the trochlear area of ​​the finger joint, the limited freedom of flexion of the metacarpophalangeal joint, and the poor breathability of the sweat gland distribution area.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An H-shaped finger movement protection tape includes a tape body and a release paper. The tape body is adhered to the upper surface of the release paper. The tape body comprises two H-shaped tape groups, with the H-shaped tape group on the left side of the tape body being the first tape and the H-shaped tape group on the right side of the tape body being the second tape. A cutting line is provided at the connection between the first and second tapes. Each H-shaped tape group of the tape body includes a base portion and a branch portion. The base portion is elongated, and the branch portion is V-shaped. The base portion is adapted to the inner trochlear region of the finger joint, and the end of the branch portion bends away from the outer side of the joint. The shape of the release paper is adapted to the shape of the tape body.

[0008] Preferably, the base portion has a length of 3-5cm and a width of 1.5-1.8cm, the branch portion has a length of 2-4cm and a width of 0.8-1.2cm, and the branch portions are symmetrically arranged on the left and right sides of the base portion.

[0009] The above technical solution, with its base and branch lengths precisely designed to fit the anatomical structure of the trochlear region on the inner side of the finger joint, and its symmetrically distributed branches to avoid covering the outer side of the joint, reduces unnecessary coverage by 30% compared to traditional large-size H-shaped tapes, ensuring that the finger flexion angle is not restricted.

[0010] Preferably, the bottom of the base portion is coated with medical pressure-sensitive adhesive, and the thickness of the medical pressure-sensitive adhesive layer is 0.05-0.1 mm.

[0011] Using the above technical solution, the medical pressure-sensitive adhesive at the bottom of the base has moderate adhesion, which can not only stably fix the main body of the tape, but also avoid pulling the skin and causing pain when tearing it off. It has a lower allergy rate than ordinary tape adhesive layers and is suitable for sensitive skin.

[0012] Preferably, the connection between the branch and the base is provided with a rounded corner transition, and the radius of the rounded corner is 0.3-0.5mm.

[0013] By adopting the above technical solution, the rounded transition at the connection between the branch and the base eliminates the friction and stimulation of the skin by the right-angle edge, reduces the coefficient of friction between the tape edge and the skin during movement, and solves the problem that the right-angle edge of traditional tape is prone to abrasion of the skin.

[0014] Preferably, the surface of the tape body is provided with anti-slip texture, and the anti-slip texture is in the form of an oblique grid, with a grid spacing of 0.5-1mm.

[0015] By adopting the above technical solution, the diagonal grid-like anti-slip texture on the surface of the tape body can increase the friction between the tape and external facilities, prevent displacement of the tape position caused by the bending and stretching of the fingers during movement, and improve the fixation stability compared to the design without anti-slip texture.

[0016] Preferably, the tape body is an integrally formed breathable elastic tape, and the surface of the tape body has evenly distributed breathable holes with a diameter of 0.1-0.3mm.

[0017] By adopting the above technical solution, the breathable holes with a diameter of 0.1-0.3mm on the surface of the tape body, combined with the one-piece molded breathable elastic substrate, improve breathability, accelerate the evaporation rate of sweat, solve the problems of stuffiness and sweat accumulation caused by traditional multi-layer wrapping tape, and reduce the tape shedding rate.

[0018] Preferably, a non-adhesive area is provided at the edge where the cut line of the tape body connects with the release paper.

[0019] By adopting the above technical solution, the glue-free area at the connection between the cutting line and the release paper can avoid the adhesive layer from overflowing and sticking to the edge of the tape body, shortening the operation time when tearing off the release paper. In addition, the glue-free area reduces the adhesion and irritation of the tape edge to the skin, improving wearing comfort.

[0020] Compared with the prior art, the beneficial effects of this utility model are: this H-shaped finger movement protective tape, 1. Precise fit, balancing protection and flexibility: The base and branch sections are precisely sized to fit the inner trochlear area of ​​the finger joint, and the curved design at the end of the branch section avoids the outer side of the joint. This provides effective support for the tendon trochlear system while avoiding restriction of the finger flexion angle, solving the problem of limited movement caused by the excessive coverage of large-size H-shaped tape. 2. Comfortable and secure fit, reducing the risk of irritation and detachment: The medical pressure-sensitive adhesive at the bottom of the base has moderate adhesion, and the rounded corners at the connection between the branch and the base reduce the pulling and friction irritation of the tape on the skin; at the same time, the anti-slip texture and breathable holes on the surface of the tape body improve the stability and breathability of the fixation, reducing the detachment rate after a full day of exercise. 3. Convenient to use and improves operational efficiency: The main body of the tape is divided into the first tape and the second tape by the cutting line. With the non-adhesive area on the edge of the release paper, the release paper can be quickly separated and torn off. The operation time for a single person is shortened, which solves the problem of complicated and time-consuming cross-winding operation and meets the needs of rapid protection during sports.

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: An H-shaped finger movement protection tape includes a tape body 1 and a release paper 2. The tape body 1 is adhered to the upper surface of the release paper 2. The tape body 1 includes two H-shaped tape groups, with the left H-shaped tape group of the tape body 1 being the first tape 101 and the right H-shaped tape group of the tape body 1 being the second tape 102. A cutting line 6 is provided at the connection between the first tape 101 and the second tape 102. Each H-shaped tape group of the tape body 1 includes a base portion 4 and a branch portion 5. The base portion 4 is elongated, and the branch portion 5 is V-shaped. The base portion 4 is adapted to the inner trochlear area of ​​the finger joint, and the end of the branch portion 5 is bent away from the outer side of the joint. The shape of the release paper 2 is adapted to the shape of the tape body 1.

[0025] The base part 4 is 3-5cm long and 1.5-1.8cm wide, and the branch part 5 is 2-4cm long and 0.8-1.2cm wide. The branch parts 5 are symmetrically arranged on the left and right sides of the base part 4. The length design of the base part 4 and the branch part 5 is precisely adapted to the anatomical structure of the trochlear area on the inner side of the finger joint. The symmetrical distribution of the branches avoids covering the outer side of the joint, reducing the unnecessary coverage area by 30% compared with the traditional large-size H-shaped tape, ensuring that the finger flexion angle is not restricted.

[0026] The bottom of the base part 4 is coated with medical pressure-sensitive adhesive, and the thickness of the medical pressure-sensitive adhesive layer is 0.05-0.1mm. The connection between the branch part 5 and the base part 4 is provided with a rounded transition, and the radius of the rounded corner is 0.3-0.5mm. The medical pressure-sensitive adhesive at the bottom of the base part 4 has moderate adhesion, which can not only stably fix the tape body 1, but also avoid pulling the skin and causing pain when tearing it off. Compared with ordinary tape, the allergy rate is reduced, making it suitable for sensitive skin. The rounded transition at the connection between the branch part 5 and the base part 4 eliminates the friction irritation of the right-angle edge to the skin. The coefficient of friction between the tape edge and the skin is reduced during movement, solving the problem that the right-angle edge of traditional tape is easy to chafe the skin.

[0027] The surface of the tape body 1 is provided with anti-slip texture, which is in the form of a diagonal grid with a grid spacing of 0.5-1mm. The tape body 1 is a one-piece molded breathable elastic tape, and the surface of the tape body 1 is evenly distributed with ventilation holes with a diameter of 0.1-0.3mm. The diagonal grid-like anti-slip texture on the surface of the tape body 1 can increase the friction between the tape and external facilities, preventing displacement of the tape position due to finger bending and stretching during exercise, and improving the fixation stability compared to designs without anti-slip texture. The ventilation holes with a diameter of 0.1-0.3mm on the surface of the tape body 1, combined with the one-piece molded breathable elastic substrate, improve breathability, accelerate the sweat evaporation rate, solve the problems of stuffiness and sweat accumulation caused by traditional multi-layer wrapped tape, and reduce the tape shedding rate.

[0028] A glue-free area 3 is provided at the edge where the cut line 6 of the tape body 1 connects with the release paper 2. The glue-free area 3 at the connection between the cut line 6 and the release paper 2 can prevent the edge of the tape body 1 from sticking due to the overflow of adhesive layer, shorten the operation time when tearing off the release paper 2, and reduce the adhesion and irritation of the tape edge to the skin, thus improving wearing comfort.

[0029] Working principle: In use, the user can separate the first tape 101 and the second tape 102 along the cutting line 6, and tear off the release paper 2 from the non-adhesive area 3; align the base part 4 with the inner trochlear area of ​​the finger joint, and fix it with the medical pressure-sensitive adhesive at the bottom; the branch part 5 naturally fits the sides of the finger due to its curved design; during exercise, the anti-slip texture prevents the tape from shifting, the vents promote sweat excretion, and the rounded corners reduce skin friction, together achieving protection and support for the finger joint.

[0030] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] 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.
