Description
Technical Field
[0001] This invention relates to the medical field, and more specifically to a physiotherapy device for preventing scar hyperplasia in early-stage wounds following lower limb burns. Background Technology
[0002] With the rapid development of modern industry, numerous applications of existing technologies have been implemented in the medical field for early intervention and prevention of burn scars. Among existing products, the use of ultraviolet (UV) therapy technology primarily involves localized irradiation of the affected area to promote wound healing. However, for patients with large or long burn areas, the treatment process is slow, and inconsistent recovery speeds lead to diverse wound surfaces, which is detrimental to scar prevention. For example, CN205055208U, a foot and leg irradiation device, utilizes multi-peak broadband energy nanometer wave therapy to simultaneously irradiate the feet and legs. By irradiating acupoints and nerves in the feet and legs, it promotes blood circulation throughout the body, showing good therapeutic effects on leg phlebitis and skin diseases of the feet and legs. This utility model foot and leg irradiation device needs to be installed on a seat, making adjustment and installation convenient and practical, suitable for the general public as a multi-peak broadband nanometer wave physical therapy instrument. While the aforementioned lower limb light wave irradiation therapy device has a simple and practical structure, it cannot treat the entire leg. In contrast, the device provided by this invention can treat the entire leg.
[0003] For example, CN222172543U discloses a size-adjustable breathable leg fixation device. This application provides a size-adjustable breathable leg fixation device, relating to the technical field of leg fixation devices. It includes a fixation device body and an adjustment box. The fixation device body is mainly used for leg fixation, and the adjustment box is located on one side of the fixation device body. The adjustment box has an internal mounting groove, and an adjustment button is installed on the outside of the mounting groove. One end of the adjustment button is fixedly connected to a connecting rod, and the other end of the connecting rod has a rotating shaft. A rotating gear is installed outside the rotating shaft, and a toothed belt is fixedly installed outside the rotating gear. The toothed belt meshes with the rotating gear. The key technical point is that when the length of the leg fixation device needs to be adjusted according to the different leg lengths of patients, the adjustment button is rotated to adjust the position of the sliding box at the upper end of the fixation device body. After the sliding box is adjusted to the required length, the leg is placed on the upper end of the sliding box for fixation. The adjustable fixation for the lower limbs described in this invention cannot be adjusted for the entire leg; it can only support and fix a local area of the leg. Given the diversity of human body shapes, this may cause discomfort to obese or thin individuals. Therefore, this invention is not suitable for all people. Summary of the Invention

[0035] This invention provides a physiotherapy device for early treatment of lower limb burn wounds to prevent hypertrophic scarring. Its working principle is as follows: Existing products often utilize ultraviolet (UV) therapy to locally irradiate the affected area to promote wound healing. However, for patients with large and elongated burn areas, the treatment process is slow, and inconsistent recovery speeds lead to diverse wound surfaces, which is detrimental to scar prevention. Therefore, this invention provides an early treatment device for lower limb burns to prevent hypertrophic scarring. It provides overall positioning and fixation of the patient's lower limb. During fixation, individual adjustments can be made according to different diameter areas, such as the ankle joint and the groin. First, the optical axes A101 and B104 in the external connection assembly 1 are connected to the connecting blocks E in the first adapter mechanism 2 and the second adapter mechanism 3. 202. Connecting block F203 is fixedly connected, wherein it is fixedly connected to the annular bracket B214 in the first adapter mechanism 2 through connecting blocks B103 and D106 in the external connecting assembly 1, and fixedly connected to the annular bracket B214 in the second adapter mechanism 3 through connecting blocks A102 and C105 in the external connecting assembly 1. The patient's entire leg is inserted through the second adapter mechanism 3, passes through the external connecting assembly 1, and then exits through the first adapter mechanism 2. Then, the rotating handle screw shaft 205 is rotated. The rotating handle screw shaft 205 moves downward linearly along the bracket A204. During the movement, the spring A206 drives the restraint belt fixing plate 207 to move downward. Among them, the bracket A204, the rotating handle screw shaft 205, and the spring A206 are fixedly connected. Spring A206 and restraint strap fixing plate 207 are both circumferentially equally divided and mounted on ring bracket A201 in the first adapter mechanism 2 and the second adapter mechanism 3, as shown in the attached drawings of the instruction manual. Therefore, in the first adapter mechanism 2, continue to adjust the other two sets of rotating handle screw shafts 205 until the patient's ankle is positioned, fixed, and clamped by the three sets of restraint strap fixing plates 207. Since the first adapter mechanism 2 and the second adapter mechanism 3 have the same structure and function, this section will focus on the first adapter mechanism 2. After adjusting the first adapter mechanism 2, continue to adjust the three sets of rotating handle screw shafts 205 in the second adapter mechanism 3 to center them on the patient's groin. Subsequently, based on the burn location and coverage area of the patient's lower limb, and the wound coverage along the lower limb axis, The number and angle of the full-width treatment mechanism 4 are customized according to the installation angle. A certain number of full-width treatment mechanisms 4 are inserted into the output shaft of the universal coupling 220 of the first adapter mechanism 2 and the second adapter mechanism 3 according to the actual situation. The ultraviolet lamp 402 in the full-width treatment mechanism 4 is rotated and adjusted to face the patient's leg wound. In order to make the assembled full-width treatment mechanism 4 approximately parallel to the line angle of the patient's leg, the motor 215 in the first adapter mechanism 2 is started. When its output shaft rotates, it drives the gear 216 to rotate. The gear 216 drives the gear ring 212 to rotate. The gear ring 212 drives the arc-shaped track rotating plate 211 to rotate. When the arc-shaped track rotating plate 211 rotates, it drives the sliding piece 209 to slide along the inner groove of the slide bracket 208 through the pin 210.During sliding, the sliding plates 209 of the circular array uniformly retract inward towards the center point, forming an iris mechanism. During extension and retraction, the sliding plates 209 press against the shaft A221, which in turn drives the limiting sleeve 219 to slide directionally along the groove of the positioning plate A217. When the shaft A221 is compressed, it remains connected to the slide rail bracket 208 through the spring seat 222 and the spring B223. When the limiting sleeve 219 moves, it drives one end of the full-width treatment mechanism 4 to tilt downward through the universal coupling 220, and then proceeds according to the above steps. Adjust the same components of the second adapter mechanism 3 until it roughly matches the patient's leg shape without interference. Simultaneously stop the motors 215 in the first adapter mechanism 2 and the second adapter mechanism 3. Then turn on the ultraviolet lamps 402 in all full-width treatment mechanisms 4 and fix the built-in reflectors 107 to the first adapter mechanism 2 and the second adapter mechanism 3. Begin treating the patient's wound. When there is a lot of necrotic tissue or purulent discharge and poor granulation tissue growth, use a medium or strong erythema dose of ultraviolet lamp 402. When the discharge decreases or fresh granulation tissue is exposed after scab removal, reduce the dose to the threshold erythema dose. For shallow and fresh wounds, use a sub-erythema dose of ultraviolet light until the wound heals. Early intervention and care of the wound can reduce the probability of scar hyperplasia and adhesion in the middle and late stages.
[0036] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
