FINGER SPRINT ASSEMBLY WITH IMPROVED CLAMPING FORCE}

The present invention relates to a finger sprint assembly, and more specifically, to a finger sprint assembly that provides a local fixation range for the finger sprint used during manual therapy, increases fixation force, and can further provide treatment in parallel.

Among the joints, manual therapy for the fingers is performed on patients who use their hands excessively or have finger numbness, fractures, ligament damage, carpal tunnel syndrome, etc., stretching the fingers using a separate protector that surrounds the fingers. This exercise method is used in parallel, and at this time, the protector is called a sprint and the sprint used on the fingers is called a finger sprint.

Finger sprints are structured to surround fingers with diseases, etc., and unlike known bands or bandages, they serve the role of treating diseases while ensuring constant movement.

As a prior art for such a sprint, the 'integrated sprint for orthopedics' is disclosed in Korean Patent No. 10-2271801. The integrated sprint for orthopedics according to the prior art includes a sprint impregnated with a hydraulic resin, a body on which the sprint is seated and which surrounds the affected area, which is made of a material with a ventilation hole, and an adhesive layer on one side to be attached to the body. It is characterized by including a protective member that adheres to the body so that the seated sprint is not exposed to the outside.

This prior art sprint is characterized by a simple structure and improved ease of use, but it has the disadvantage that control of the range of motion is excessive in areas with a wide range of motion, such as fingers, which may cause discomfort.

The finger sprint shown in Figure 1 is Korean Patent No. 10-2286026 invented by the present inventor, and includes a metal base sheet (1) of a certain length and width surrounding the finger; A base hole 10 formed through a diamond shape at the center side of the base sheet 1; a first hole 20 extending through a portion of the finger around the upper left and right sides of the base hole 10; Characterized in that it includes a second hole (30) extending through the lower left and right sides of the base hole (10) along the circumference of the finger to correspond to the position and size of the first hole (20), When worn on the finger, it is possible to secure the finger while ensuring a certain range of motion.

However, since the finger sprint shown in FIG. 1 is designed to be provided with the first hole 20 and the second hole 30, it has a structure in which the fixation range interferes with both joints of the finger, and the finger is localized. By fixing it, it was not possible to guarantee a smooth range of motion of one joint.

We would like to provide a sprint assembly.

However, the technical challenges that this embodiment aims to achieve are not limited to the technical challenges described above, and other technical challenges may exist.

The finger sprint assembly according to an embodiment of the present invention is a finger sprint in which a plurality of 'C' shaped rings are formed at a predetermined distance apart, and the longitudinal shape when surrounding the finger is trapezoidal, the ' It may include a fixture that is attached and detachable to the open portion of the C'-shaped ring to secure the finger sprint and the finger, and a strap that is attached and detachable to the fixture and surrounds the finger sprint, the fixture, and the finger.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the presented embodiments, and those skilled in the art who understand the spirit of the present invention may add, change, or delete other components within the scope of the same spirit, or create other degenerative inventions or this invention. Other embodiments that are included within the scope of the invention can be easily proposed, but this will also be said to be included within the scope of the invention of the present application.

Figure 1 is a perspective view showing a conventional finger sprint.

Referring to FIG. 1, a conventional finger sprint includes a base sheet 1 made of metal with a certain length and width surrounding the finger, a base hole 10 formed through a diamond shape at the center of the base sheet 1, and A first hole 20 extends through a portion of the finger around the upper left and right sides of the base hole 10, and a first hole 20 extends along the finger around the lower left and right sides of the base hole 10. It includes a second hole 30 extending through the hole 20 to correspond to its location and size.

Since the conventional finger sprint is designed to be provided with the first hole 20 and the second hole 30, it adopts a structure in which the fixation range interferes with both joints of the finger, and the finger is locally fixed to one Smooth range of motion of the joint could not be guaranteed.

In addition, the conventional finger sprint is provided with a fixing band (not shown), which is a strip-shaped structure attached to the area between the base sheet 1 and the first hole 20 and the area between the second hole 30, Although it assists the fixing performance of the finger sprint, the fixing band (not shown) is attached to the base sheet 1 through the adhesive layer on the back, and when the life of the adhesive layer expires, the fixing band (not shown) A problem arose that prevented the device from performing its role (not shown).

Figure 2 is an overall perspective view of the finger sprint assembly according to one embodiment of the present invention.

Referring to Figure 2, the finger sprint assembly according to an embodiment of the present invention is formed with a plurality of 'C' shaped rings spaced a predetermined distance apart, so that the longitudinal shape when surrounding the finger is trapezoidal. A finger sprint 100 is attached and detached to the open portion of the 'C' shaped ring, and is attached to and detached from the fixture 200 to secure the finger sprint 100 and the finger, and the finger sprint. It may include (100), the fixture 200, and a strap 300 surrounding the finger.

Figure 3 is a top view of a finger sprint according to an embodiment of the present invention.

Referring to Figures 2 and 3, the finger sprint 100 may have a trapezoidal longitudinal shape when surrounding the finger, and may have an oval shape when the finger sprint 100 is deployed.

For example, the finger sprint 100 may be shaped so that the center point of the oval is located at the finger joint so that the long axis of the oval surrounds both sides of the finger. As a result, the finger sprint 100 is spaced a predetermined distance apart. A plurality of 'C' shaped rings may be formed.

For example, the finger sprint 100 may be provided with a first ring 110 and a second ring 120 with a larger diameter than the first ring 110, and the first ring 110 and the second ring 120 may be provided with a larger diameter than the first ring 110. The two rings 120 may be connected to form a predetermined angle D100.

For example, the first ring 110 may have a smaller diameter than the second ring 120.

At this time, the user can determine the direction of finger insertion into the finger sprint 100 by looking at the difference in diameter between the first ring 110 and the second ring 120.

Preferably, the diameter of the first ring 110 and the diameter of the second ring 120 may be 1:1.03 to 1:1.05. This is an ergonomic design value that reflects the typical finger shape where the finger becomes thicker as it moves from the end of the nail to the palm.

However, it is not limited to this, and the diameter of the first ring 110 and the diameter of the second ring 120 can be modified in various ways as will be obvious to those skilled in the art.

In addition, the finger sprint 100 may have a predetermined space S100 formed so that the finger joints are located in the space between the first ring 110 and the second ring 120.

For example, the predetermined angle D100 may be 50 to 120 degrees, and most preferably 80 degrees. This is because when wearing the finger sprint 100, the seating feeling and fixing force when the finger joint is located in the predetermined space (S100) between the first ring 110 and the second ring 120 are taken into consideration. It could be an angle. The predetermined angle (D100) can vary within the range of 50 to 120 degrees depending on the length between the user's finger joints, and if the predetermined angle (D100) is less than 50 degrees, the predetermined movement ability of the finger is limited. If the predetermined angle (D100) exceeds 120 degrees, it may invade other finger joints that do not want to be fixed. Additionally, the predetermined angle D100 is an ergonomic design value that reflects a typical finger shape.

However, it is not limited to this, and the predetermined angle D100 can be modified in various ways at a level that is obvious to those skilled in the art.

Additionally, the finger sprint 100 may be connected to each other by rounding the open end of the first ring 110 and the open end of the second ring 120. Here, the opening end refers to the opening part of the 'C' shaped ring, and a fixture 200, which will be described later, can be attached and detached from the opening end.

For example, the portion C100 where the open end of the first ring 110 and the open end of the second ring 120 are connected may be formed to be spaced apart by a predetermined distance D200.

For example, the finger sprint 100 has a portion C100 where the open end of the first ring 110 and the open end of the second ring 120 are connected to each other by a predetermined distance D200, so that the finger Elasticity may be provided to the sprint 100.

Here, the elastic force is a force generated due to the 'C' shape of the first ring 110 and the second ring 120. When the finger sprint 100 is worn due to the elastic force, the finger sprint ( 100) can be slightly spread on both sides of the fingers, allowing the user to wear the finger sprint 100 more easily.

For example, the predetermined distance (D200) may preferably be 1 to 3 mm, and if the predetermined distance (D200) exceeds 3 mm, a gap occurs between the finger sprint 100 and the finger, thereby reducing the fixing force. It may be weakened, and when the predetermined distance (D200) is less than 1 mm, the elastic force limits the finger sprint 100 from opening to both sides of the fingers, so the wearing comfort of the finger sprint 100 may be reduced. .

Additionally, the material of the finger sprint 100 may be made only of biodegradable plastic composite.

For example, if the finger sprint 100 is made only of a biodegradable plastic composite, when the finger sprint 100 is disposed of, all parts may be decomposed by microorganisms, etc. Therefore, air pollution or soil pollution caused by contaminants generated when disposing of the finger sprint 100 can be reduced. Specifically, when the biodegradable plastic decomposes, natural by-products such as carbon dioxide, nitrogen, water, biomass, and inorganic salts or low-molecular-weight compounds such as methane are generated as decomposition products. Additionally, because it takes a short period of time to decompose compared to existing plastics, it can be environmentally friendly.

In addition, the biodegradable plastic composite includes polycaprolactone (PCL), polylactic acid (PLA), polyvinyl alcohol (PVA), polybutylene succinate (PBS), and poly Butylene adipate-co-terephthalate (PBAT), polyhydroxyalkanoate (PHA), polyglycolic acid (PGA), polyorthoester, phosphagene ), polypeptide, and combinations thereof, preferably polylactic acid (PLA) and polybutylene adipate-co-terephthalate (PBAT). ) can be selected.

The polylactic acid (PLA) is a representative biodegradable polymer that can be obtained through fermentation of lactic acid or corn, and has excellent tensile strength and processability, but its strong brittleness and low elongation make it difficult to apply to industry. there is. Meanwhile, due to the use of polylactic acid (PLA) blended with polybutylene adipate-co-terephthalate (PBAT), the glass transition of polylactic acid (PLA) is reduced. As the temperature increases and the crystallization temperature decreases, the tensile strength decreases and elongation such as elongation at break increases. Therefore, by using polylactic acid (PLA) and polybutylene adipate-coterephthalate (PBAT) together, the physical properties required for the biodegradable plastic composite used in the finger sprint in the present invention There is an effect that can be obtained.

In addition, the weight ratio of polybutylene adipate-co-terephthalate (PBAT) to polylactic acid (PLA) is the polybutylene adipate-co-terephthalate (PBAT). ) The polylactic acid (PLA) weight ratio may be greater than 8 and less than 12 with respect to the weight ratio of 1.

For example, when the polylactic acid (PLA) weight ratio to the polybutylene adipateco-terephthalate (PBAT) weight ratio is 1, the tensile strength of the biodegradable plastic composite increases. Although it is effective, the brittle nature of polylactic acid (PLA) is improved and the elongation at break increases, but the maximum tensile load and tensile strength that can be endured are lower than those required in the present invention. It can happen.

For example, when the weight ratio of polylactic acid (PLA) exceeds 12 with respect to the weight ratio of polybutylene adipateco-terephthalate (PBAT) of 1, the maximum that the biodegradable plastic composite can withstand is Although it has the effect of increasing tensile load and traction tensile strength, elongation such as elongation at break decreases and cannot compensate for the brittle nature of polylactic acid (PLA), and the finger sprint (100 ) There is a risk of damage during use.

Additionally, the biodegradable plastic composite may further include carbon material. The carbon material may include a material selected from the group consisting of carbon black, carbon nanotubes, graphene, carbon fiber, and combinations thereof. By further including a carbon material in the biodegradable plastic composite, the strength and elasticity of the biodegradable plastic composite may be increased and the weight may be reduced.

Additionally, the content of carbon material may be 50 to 150 parts by weight relative to 100 parts by weight of the biodegradable plastic. If the content of the carbon material is less than 50 parts by weight, the strength and elasticity of the biodegradable plastic composite may decrease, and there is a risk that the physical properties required in the present invention may not be satisfied. If the content of the carbon material exceeds 150 parts by weight, there is a risk that the strength and elasticity may increase more than necessary.

Additionally, the finger sprint 100 may have an average maximum tensile load of 2,890 N or more. The average maximum tensile load of the finger sprint (100) was measured using a Universal Testing Machine (UTM). The analysis speed was 50 mm/min, the load cell was 30000 N, and the analysis environment was a temperature of 21~23℃ and a relative humidity of 40~50%. The finger sprint 100 may have an average maximum tensile load of 2,890 N or more, preferably 2,950 N or more, and more preferably 3,000 N or more. If the average maximum tensile load is less than 2,890 N, there is a risk that the finger sprint 100 may be damaged.

Specifically, the method of manufacturing the biodegradable plastic composite may consist of a material melting step and a mold injection step.

Material melting step (S11)

The weight ratio of polylactic acid (PLA) to polybutylene adipate-co-terephthalate (PBAT) is mixed at 1:8 to 1:12 and melted at a temperature of 170 to 180°C.

Mold injection step (S12)

The molten material is injected into a previously prepared finger sprint mold, the mold is heated to a temperature of 170 to 200°C for 1 hour, then cooled to a temperature of 30°C, and more than 30 minutes have passed since cooling to 30°C. The product is later separated from the mold.

Therefore, by manufacturing the finger sprint 100 from a biodegradable plastic composite with appropriate rigidity, it can be environmentally friendly.

However, the material of the finger sprint 100 is not limited to this and can be modified in various ways as will be obvious to those skilled in the art. For example, it may be made of a metal material.

In addition, when the finger sprint 100 is worn, a reinforcement layer (P100) containing a functional composition may be attached to the surface facing the finger.

For example, the reinforcement layer (P100) includes 90 to 99 parts by weight of an elastic material such as silicone or rubber, and reinforcement material 1 to 1 containing alkyl acrylate, which is any one of methyl acrylate, ethyl acrylate, and propyl acrylate. It may contain 10 parts by weight.

Here, alkyl acrylate has water-repellent properties and has the characteristic of providing an additional water-repellent function when added to the composition of the reinforcing layer (P100). Moreover, it has adhesiveness, which makes the reinforcing layer (P100) anti-slip, that is, non-slip. can be further improved.

For this reason, by adding a reinforcing material containing alkyl acrylate, the reinforcing layer (P100) in direct contact with the skin of the finger becomes water-repellent, preventing contamination by sweat discharged from the skin, and further increasing non-slip properties to increase pressure. You can more effectively prevent your finger from coming off.

Specifically, the reinforcing material may be composed of the steps of preparing a first solution, preparing a second solution, and completing the reinforcing material.

Preparing the first solution (S21)

First, a first solution is prepared by mixing 15 to 25 parts by weight of alkyl acrylate, 20 to 30 parts by weight of ethylene vinyl acetate (EVA), and 45 to 60 parts by weight of toluene.

At this time, alkyl acrylate is a material with water-repellent properties and adhesiveness, and toluene is added as a solvent in the first solution.

In addition, ethylene vinyl acetate (EVA) is a copolymer of ethylene monomer and vinyl acetate (VA) monomer, and has excellent shock absorption at low temperatures due to its flexible properties, weather resistance, tear strength, and stress crack resistance. , It has good ozone resistance and excellent adhesion and processability. Therefore, by adding ethylene vinyl acetate, weather resistance, tear strength, stress crack resistance, and ozone resistance can be improved, and non-slip properties can be strengthened by increasing adhesion.

Preparing a second solution (S22)

Next, 75 to 85 parts by weight of the first solution, 15 to 20 parts by weight of polyvinylidene fluoride, 5 to 10 parts by weight of phosphorous ester, and 3 to 10 parts by weight of benzotriazole. Mix to prepare a second solution.

At this time, polyvinylidene fluoride is a thermoplastic fluoropolymer that has excellent chemical resistance and a high melting point of 171 degrees Celsius. Unlike other fluoropolymers, polyvinylidene fluoride is a material that exhibits excellent mechanical properties and has excellent chemical resistance and impact resistance. Therefore, the chemical resistance of the reinforcing material as well as the reinforcing layer (P100) can be improved by adding polyvinylidene fluoride.

In addition, phosphorous acid ester is a phosphorous acid-based ester that acts as an antioxidant to prevent the reinforcing layer (P100) containing elastic material from being oxidized and deteriorating quality due to contact with moisture, especially sweat. It is added for

In addition, benzotriazole is a colorless, granular compound with a needle-shaped crystal structure, and can be added to function as a stabilizer against UV. This benzotriazole reduces and delays the penetration of ultraviolet rays, which can help prevent the reinforcing layer (P100) from being oxidized and deteriorating in quality due to exposure to ultraviolet rays.

Step of completing reinforcement (S23)

Finally, 85 to 95 parts by weight of the second solution are mixed with 5 to 10 parts by weight of polybutylene adipate terephthalate and 1 to 10 parts by weight of a discoloration blocker containing zinc oxide. This completes the reinforcement.

Here, polybutylene adipate-co-tere phthalate is an eco-friendly polymer material that is harmless to the human body. It is an eco-friendly polymer material and has high strength characteristics, so when added to a reinforcement material, a reinforcing layer containing such reinforcement material is used. (P100) plays a role in improving the physical properties and enhancing strength.

In addition, the discoloration blocker is characterized by containing zinc oxide as an active ingredient. This zinc oxide can improve structural stability and promote durability and heat resistance, and can cause coloring and coloring of the reinforcing layer (P100), which is the surface in contact with the skin. It plays a role in preventing phenomena such as material deformation and functional deterioration, and as a result, it can help preserve the functional stability of the reinforcement layer (P100).

Therefore, reinforcing materials containing the specific composition and manufacturing process described above are added to the reinforcing layer (P100) to increase water repellency to prevent contamination or deterioration in function due to sweat discharged from the human body, and to enhance non-slip properties by increasing adhesion, thereby preventing pressure. Not only can it prevent finger sprints from unnecessarily detaching from the finger to be fixed, but it can also be expected to have high strength and chemical resistance, and can prevent discoloration even when exposed to repeated use or sweat.

Additionally, a drug adhesive layer (P200) may be applied to one side of the reinforcement layer (P100).

For example, the drug adhesive layer (P200) is a layer with adhesive properties containing an active drug such as an anti-inflammatory analgesic ingredient, and is applied to the reinforcing layer (P100) of the finger sprint (100) It increases the fixation power and can provide pharmacological efficacy by allowing the effective drug to be absorbed through the skin.

In addition, the drug adhesive layer (P200) may be applied to the entire surface of the reinforcing layer (P100), may be applied only to a local area, or may be applied directly on the finger sprint 100 without the reinforcing layer (P100). .

However, without being limited to this, the area where the drug adhesive layer (P200) is applied can be modified in various ways as will be obvious to those skilled in the art.

The drug adhesive layer (P200) may include 5 to 70 parts by weight of the drug composition, 50 to 90 parts by weight of the adhesive polymer, 1 to 70 parts by weight of the plasticizer, and the remaining amount of solvent, based on a total of 100 parts by weight.

For example, the drug composition may include 50 to 99 parts by weight of the first alcohol, 0.01 to 2 parts by weight of the second alcohol, 0.01 to 2 parts by weight of the organic acid, and 0.1 to 40 parts by weight of the active agent, based on a total of 100 parts by weight. .

For example, the first alcohol may be one or more selected from propylene glycol, butylene glycol, glycerol, dipropylene glycol, and octanediol.

For example, the second alcohol may be one or more selected from lauryl alcohol, myristyl alcohol, cetyl alcohol, hexyldecanol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, aracyl alcohol, and octyldodecanol. there is.

For example, the organic acids include acetic acid, lactic acid, tartaric acid, citric acid, benzoic acid, caproic acid, enanthic acid, caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, linoleic acid and ara. It may be one or more selected from chidic acid, where the organic acid acts to increase the solubility of the active drug in the composition and on the skin, thereby promoting transdermal absorption of the drug composition.

For example, the active drug may be a drug that can relieve anti-inflammatory pain and/or neuropathic pain, and the drug content of the active drug is preferably saturated.

For example, the active drug may be at least one selected from pregabalin, gabapentin, tramadol, piroxicam, and ketoprofen, but is not limited thereto, and may include any active drug that can be used in manual therapy. .

For example, the adhesive polymer may include an acrylic polymer containing a (meth)acrylic acid ester polymer; Rubber-based polymers such as styrene-isoprene-styrene block copolymer, styrene-butadiene-styrene block copolymer, polyisoprene, polyisobutylene, polybutadiene, etc.; Silicone-based polymers such as silicone rubber, dimethylsiloxane base, diphenylsiloxane base, etc.; vinyl ether polymers such as polyvinyl methyl ether, polyvinyl ethyl ether, polyvinyl isobutyl ether, etc.; vinyl ester polymers such as vinyl acetate-ethylene copolymer; It may be at least one type selected from the group consisting of an ester polymer consisting of a carboxylic acid component such as dimethyl terephthalate, dimethyl isophthalate, dimethyl phthalate, etc., and a polyhydric alcohol such as ethylene glycol, and the adhesive polymer may be selected from the group consisting of pressure-sensitive adhesiveness of the drug adhesive layer, An acrylic polymer may be preferably selected from the viewpoint of cohesiveness and drug release properties.

For example, the solvent may be any one of ethyl acetate, toluene, and hexane, but is not limited thereto and may be modified in various ways as will be apparent to those skilled in the art.

For example, the plasticizer includes oils and fats such as olive oil, castor oil, squalene, and lanolin; organic solvents such as decylmethyl sulfoxide, methyloctyl sulfoxide, dimethyl sulfoxide, dimethylformamide, dimethylacetamide, methylpyrrolidone, and dodecylpyrrolidone; surfactants such as polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester and polyoxyethylene fatty acid ester; phthalic acid esters such as dibutyl phthalate, diheptyl phthalate, and dioctyl phthalate; Sebacic acid esters such as diethyl sebacate, dibutyl sebacate, and dioctyl sebacate; Hydrocarbons such as liquid paripin; Fatty acid esters such as ethyl oleate, diisopropyl adipate, isopropyl palmitate, octyl palmitate, isopropyl myrstate, isotridecyl myrstate, and ethyl laurate; one selected from the group consisting of It could be more than that.

However, the plasticizer is not limited to this, and the type is specifically limited if the plasticizer plasticizes the drug adhesive layer (P200) to give a soft feeling to the drug adhesive layer and reduces pain or skin irritation due to skin adhesion when peeling from the skin. It doesn't work.

In addition, the application thickness of the drug adhesive layer (P200) is preferably 20 to 300 ㎛, more preferably 30 to 300 ㎛, and most preferably 50 to 300 ㎛. For example, if the thickness of the drug adhesive layer (P200) is less than 20 ㎛, it may be difficult to obtain sufficient adhesive strength and contain an effective amount of drug, and if the thickness exceeds 300 ㎛, the drug adhesive layer (P200) Application may become difficult.

Specifically, the drug adhesive layer (P200) may be composed of the steps of preparing a drug composition, preparing a drug adhesive layer, and applying/drying the drug adhesive layer.

Preparing a drug composition (S31)

First, a drug composition is prepared by mixing 50 to 99 parts by weight of the first alcohol, 0.01 to 2 parts by weight of the second alcohol, 0.01 to 2 parts by weight of the organic acid, and 0.1 to 40 parts by weight of the active agent.

At this time, the first alcohol may be propylene glycol, the second alcohol may be octyldodecanol, the organic acid may be citric acid, and the active agent may be piroxicam.

Step of manufacturing a drug adhesive layer (S32)

Next, 5 to 70 parts by weight of the drug composition, 50 to 90 parts by weight of the adhesive polymer, 1 to 70 parts by weight of the plasticizer, and the remaining amount of solvent are mixed to prepare a drug adhesive layer.

At this time, the adhesive polymer is an acrylic polymer that has good adhesion to human skin and can easily repeat adhesion and peeling, and is preferably 2-ethylhexyl acrylate, acrylic acid, and N-vinyl-2-p. (meth)acrylic acid alkyl ester, a copolymer of rolidone, can be used. Additionally, the plasticizer may be ethyl oleate.

Step of applying/drying the drug adhesive layer (S33)

Finally, the drug adhesive layer is applied to a thickness of 20-300 ㎛ on one side of the reinforcement layer (P100) and dried.

Therefore, the drug adhesive layer (P200) containing the specific composition and manufacturing process described above is applied to one side of the reinforcing layer (P100), so that the finger sprint (100) stably fixes the user's finger and at the same time, the active drug is transdermally administered. It can also be absorbed and provide pharmacological efficacy.

Figure 4 is a diagram for explaining a fixture bound to a finger sprint according to an embodiment of the present invention.

Referring to FIG. 4, the fixture 200 includes a first flange 210, a second flange 220, and a web 230 connecting the first flange 210 and the second flange 220. can do.

For example, the fixture 200 may be attached or detached to a portion C100 where the opening end of the first ring 110 and the opening end of the second ring 120 of the finger sprint 100 are connected.

Specifically, the portion where the opening end of the first ring 110 and the opening end of the second ring 120 are connected (C100, see FIG. 3) are spaced apart by a predetermined distance (D200, see FIG. 3), Depending on the spacing D200 of the area C100, the user's finger may easily fall off or it may be inconvenient to insert the finger.

For this reason, when the fixture 200 is mounted on the portion C100, a comfortable fit and appropriate fixation force can be provided when the user wears the finger sprint 100.

For example, the first flange 210 and the second flange 220 may be fitted with the open end of the finger sprint 100 along with the web 230.

In addition, the thickness (T100) of the web 230 can be adjusted to adjust the spacing (D200, see FIG. 3) of the finger sprint 100. For example, the user's finger may be used to move the finger sprint 100. If the thickness (D100) of the web 230 is somewhat thicker than that of the web 230, the gap (D200) can be spaced by the thickness (T100) of the web 230 by installing a fixture (200) larger than the basic gap (D200). there is.

In addition, the fixing force of the finger sprint 100 can be adjusted by adjusting the thickness (T200) of the second flange 220. For example, if the user's finger is somewhat thinner than the finger sprint 100, the first 2 The fixing force of the finger sprint 100 can be increased by installing a fixture 200 with a thick thickness T200 of the flange 220 so that one surface of the second flange 220 is in contact with the finger.

For example, the material of the fixture 200 may be an elastic material, preferably polyethylene, polypropylene, and polyvinyl chloride, but is not limited thereto, and may be modified in various ways at a level obvious to those skilled in the art. possible.

Figure 5 is a diagram for explaining a strap according to an embodiment of the present invention.

Referring to FIG. 5, the strap 300 extends from a first strap 310 surrounding the fixture 200 and the other end of the first strap 310 to surround the finger sprint 100 and the finger. 2 Straps 320 may be provided,

Additionally, the second strap 320 may have a strap hole H100 formed at a predetermined distance away from the other end of the first strap 310.

For example, the strap 300 may be formed of a female Velcro type (V100) on one side and a male Velcro type (V200) on the other side, and may be positioned so that the male Velcro type (V200) faces the finger.

For example, the material of the female Velcro type (V100) of the strap 300 may be a fiber material, preferably cotton, nylon, or polyester, but is not limited thereto, and at a level that is obvious to those skilled in the art. It can be modified in various ways.

For example, the male Velcro type (V200) of the strap 300 may be made of plastic, and the end may be in a hook shape or a sharp and pointed shape. For this reason, when the strap 300 touches the finger, it generates an acupressure effect on the finger and improves blood circulation, which can be helpful in manual therapy.

In addition, the strap 300 can provide pharmacological efficacy by applying a drug adhesive layer (P200) to the male Velcro type (V200) made of plastic, thereby helping with manual therapy. At this time, since the drug adhesive layer (P200) overlaps with the above-described content, detailed description will be omitted.

However, it is not limited to this, and the material and shape of the male Velcro type (V200) can be modified in various ways at a level that is obvious to those skilled in the art.

Hereinafter, looking at the fixing mechanism of the strap 300, first, the strap 300 is positioned so that the male Velcro type (V200) faces the user's finger, and the fixture 200 is connected to the first strap 310. Surrounding it, the first strap 310 penetrates the strap hole (H100), and then the male Velcro type (V200) of the first strap 310 that penetrates the strap hole (H100) is connected to the fixture (200). ) and are laminated with the female Velcro type (V100) of the first strap 310 surrounding the strap and are adhesively fixed to each other.

Next, the second strap 320 may surround the finger sprint 100 and the user's fingers. Specifically, the finger joint is located in the space (S100, see FIG. 2) between the first ring 110 and the second ring 120 of the finger sprint 100, and at this time, the second strap ( The male Velcro type (V200) of 320 surrounds the finger joint located in the space (S100), and the female Velcro type (V100) of the first and second straps (310, 320) and the second strap (320) ) of male Velcro type (V200) are stacked and glued together.

Due to this, the fixing force of the finger sprint assembly is primarily increased by the reinforcing layer (P100) of the finger sprint (100), and the drug adhesive layer (P200) applied to the reinforcing layer (P100) provides pharmacological efficacy and 2 The fixation force is increased in three ways, the fixation force can be increased in three ways by the fixture 200, and the fixation force can be increased in four ways along with the acupressure effect by the strap 300. Finally, the male Velcro type of the strap 300 In addition to the pharmacological efficacy, the drug adhesive layer (P200) applied to (V200) increases the fixation power by 5 degrees, allowing effective manual treatment of localized areas.

In the attached drawings, in order to more clearly express the technical idea of the present invention, components that are unrelated or less relevant to the technical idea of the present invention are briefly expressed or omitted.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and various changes or modifications may be made within the spirit and scope of the present invention. It is obvious to those skilled in the art, and therefore, it is stated that such changes or modifications fall within the scope of the appended patent claims.
