Description

Technical Field

[0001] This utility model relates to the field of heat therapy bandages, and more particularly to a heat therapy bandage for the arm. Background Technology

[0002] After a sports injury, you need to apply heat to the affected area. For regular areas, you can simply apply a heat patch with a heating function. For the area where the shoulder and arm connect, you need to use a special arm bandage.

[0003] Since only the lower end of the strap is tied to the patient's arm with an elastic band, and the upper end of the strap cannot be tied to the patient's arm, a longer elastic band is needed to pass through the patient's chest and under the armpit of the other arm for fixation. The elastic band is usually set to be long and the length is adjusted using a D-ring buckle. However, the operation of adjusting the D-ring buckle is cumbersome and inconvenient. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an arm heat therapy bandage that can overcome the problem of inconvenience in adjusting the length of the fixing band using a D-ring buckle in traditional technologies.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A heat therapy bandage for the arm includes an armband, with an elastic band sewn into the opening at the lower end of the armband, a fixing strap connected to the upper end of the armband, and an adjustment component for adjusting the length of the fixing strap provided on the outside of the fixing strap.

[0007] The adjustment assembly includes a take-up drum sleeved on the outside of the fixed belt, a rotating shaft rotatably connected to the inner wall of the take-up drum, the fixed belt being fixed to the rotating shaft, and an operating structure for driving the rotating shaft to rotate being installed on the take-up drum.

[0008] Preferably, the winding drum has two through slots facing each other, and the fixing belt passes through the two through slots.

[0009] Preferably, a raised ring is formed on the outer wall of the winding drum at the position opposite to the through groove.

[0010] Preferably, the rotating shaft is coaxial with the winding drum.

[0011] Preferably, the operating structure includes a worm gear fixed to the upper end of the rotating shaft, the worm gear being located inside the take-up drum, a worm being rotatably mounted on the upper end of the inner wall of the take-up drum, the worm being meshed with the worm gear, and one end of the worm extending through the take-up drum to the outer side of the take-up drum and having a knob fixed thereon.

[0012] Preferably, the outer wall of the knob is provided with anti-slip grooves at equal angular intervals.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention, by incorporating a winding drum, a rotating shaft, a worm gear, and a knob, simplifies and speeds up the adjustment of the strap length. Simply rotating the knob allows for winding and unwinding of the strap, eliminating the need for repeated pulling to pass it through the buckle. This makes it more convenient for patients to use with one hand and allows them to adjust the strap independently. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3 This embodiment provides an arm heat therapy bandage, including a fabric armband 1. The armband 1 is shaped to fit the outer side of the human arm and shoulder. The armband 1 has a built-in heating component. An elastic band 2 is sewn to the opening at the lower end of the armband 1. The end of the elastic band 2 away from the end sewn to the armband 1 is attached to the armband 1 by Velcro. A fixing strap 3 is connected to the upper end of the armband 1.

[0021] When using it, the patient puts the fixation strap 3 over their head and puts it on their chest. The side of the fixation strap 3 away from the armband 1 is placed under the patient's armpit. The armband 1 is put on the patient's shoulder and arm. The elastic band 2 is tightened and the end of the elastic band 2 is wrapped around the patient's arm and attached to the armband 1 with Velcro to complete the fixation of the arm heat therapy band.

[0022] Then, by powering the heating element, heat is applied to the arm and shoulder. The heating element is based on mature technology from existing heat therapy straps, so its specific structure and principle will not be described in detail and are not shown in the figure. Similarly, the Velcro is not shown in the figure.

[0023] A take-up drum 4 is provided on the outside of the fixed belt 3. Two through slots 401 are provided on the take-up drum 4. The fixed belt 3 passes through the two through slots 401. A rotating shaft 5 is coaxially rotatably connected to the inner wall of the through slots 401. The rotating shaft 5 is fixed to the fixed belt 3. A worm gear 6 is fixed to one end of the rotating shaft 5. A worm 7 is rotatably connected to the inner wall of the take-up drum 4 near the worm gear 6. The worm 7 is meshed with the worm gear 6. One end of the worm 7 passes through the take-up drum 4 and extends to the outside of the take-up drum 4 and is fixed with a knob 8.

[0024] When the patient passes the fixation strap 3 through the head and puts it around the chest, it is often not very tight. The length of the fixation strap 3 needs to be shortened to ensure that the arm strap 1 fits the arm and shoulder tightly. This can be achieved by turning the knob 8, which drives the worm gear 7 to rotate, causing the worm wheel 6 to rotate, which in turn causes the shaft 5 to rotate, thereby winding up the fixation strap 3. The fixation strap 3 passes through the through groove 401 and is wound around the outside of the shaft 5, and then wound up inside the winding drum 4, thus tightening the fixation strap 3.

[0025] Furthermore, a pad 9 is fixed on the outer wall of the take-up drum 4. When the patient puts the fixing strap 3 on his chest, the pad 9 is located close to the chest, thus isolating the take-up drum 4 from the patient's skin, improving wearing comfort, and preventing the take-up drum 4 from rubbing against the human skin.

[0026] Anti-slip grooves 801 are formed at equal angles on the outer wall of the knob 8 to increase the friction when holding the knob 8. A raised ring 402 is formed on the outer wall of the take-up drum 4 at the position opposite to the through groove 401. The opening of the inner wall of the raised ring 402 is set with an arc-shaped chamfer.

[0027] 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.
