Technical Field
[0001] The utility model relates to the field of leg rehabilitation exercises, and specifically relates to a sliding buffer type leg exerciser for patients. Background Technique
[0002] With the development of the transportation industry, construction industry and the sub-specialization of orthopedics, for lower limb patients admitted to the department of trauma orthopedics, during the perioperative bedridden period, in order to prevent the occurrence of complications and promote rapid recovery, lower limb functional exercises are crucial and need to rely on flexion and extension of the hip and knee joints for in-bed functional exercises. Currently, the traction beds on the Internet can only pull the lower limbs up and down, and cannot make the legs swing with the thigh root as the fulcrum, which does not conform to the physiological characteristics of leg walking and is prone to cause traction. Therefore, how to achieve effective arc swing exercises for lower limb fracture patients during the perioperative period is an urgent problem for technicians in this field. Content of the Utility Model
[0003] The purpose of the utility model is to provide a sliding buffer type leg exerciser for patients to solve the problems put forward in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A sliding buffer type leg exerciser for patients includes an inverted "U" - shaped slider sleeved on a cross - bar, a pulley installed in the slider, a pulling rope passing through the pulley, and a pulling ring arranged at the end of the pulling rope. It also includes a sliding mechanism arranged in the slider that can slide left and right. The other end of the pulling rope is connected to a supporting mechanism for the leg. When the pulling rope is pulled, the slider can slide left and right through the sliding mechanism so that the lower limb swings in an arc. The lower limb swings with the thigh root as the pivot, which is the normal movement. Currently, the commonly used traction is vertically upward, causing the leg to be pulled and stressed, resulting in discomfort. The setting of the sliding mechanism can make the pulling rope move left and right, so that the lower limb swings in an arc for exercise, which is more in line with the physiological characteristics of the body.
[0005] Preferably, the sliding mechanism includes two left - and - right rotating shafts rotatably installed in the slider. It can rotate to reduce friction.
[0006] Preferably, a rubber roller for buffering is sleeved on the rotating shaft. It reduces friction and also reduces the noise during movement.
[0007] Preferably, the supporting mechanism includes an inverted "U" - shaped soft sling installed at the end of the pulling rope, a rigid support plate arranged at the lower end of the sling, and a clamping bag for placing a cold compress bag arranged inside the sling. The clamping bag can hold a cold compress bag.
[0008] Preferably, it also includes a buffer mechanism arranged on the pulling rope to slow down the impact on the slider. When the pulling rope is released, it slows down the impact on the leg and is more gentle.
[0009] Preferably, the buffer mechanism includes a rubber ball installed on the pull rope. The rubber ball provides elastic force to achieve buffering. At the same time, it also plays a role in fixing the height of the leg.
[0010] Preferably, the rubber ball is sleeved on the pull rope, and the rubber ball is located on the side of the slider close to the pull ring. A hard spherical shell that prevents passing through the slider is installed on the rubber ball, and the end of the spherical shell pointing to the slider is open. The hard spherical shell can well prevent passing through the slider. Even if the rubber ball breaks, there is still the spherical shell for safety protection.
[0011] Preferably, the spherical shell extends in the direction of the pull ring to form a support sleeve, and a knob with an inner end pressing against the pull rope is threadedly connected to the support sleeve to achieve position adjustment. Because of the knob, the spherical shell and the rubber ball can slide on the pull rope to change the height of the leg.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. Pull the pull rope to realize the up and down movement exercise of the leg. The setting of the rotating shaft enables the slider to move along the cross bar, so that the lower limb swings in an arc shape and will not be pulled, making it more comfortable;
[0014] 2. The rubber ball can play a buffering role. Adjust the position through the knob to change the height of the leg, which is more flexible and convenient;
[0015] 3.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution for a sliding buffer type patient leg exerciser: A sliding buffer type patient leg exerciser includes an inverted "U" shaped slider 1 sleeved on a cross bar, a pulley 2 installed in the slider 1, a pulling rope 3 passing through the pulley 2, and a pulling ring 4 arranged at the end of the pulling rope 3. It further includes a sliding mechanism arranged in the slider 1 that can slide left and right, and the other end of the pulling rope 3 is connected to a leg support mechanism. When the pulling rope 3 is pulled, the slider 1 can slide left and right through the sliding mechanism to make the lower limb swing in an arc. The lower limb swings with the thigh root as the center, which is the normal movement. Currently, the commonly used pulling is vertically upward, causing the leg to be pulled and stressed, resulting in discomfort. The setting of the sliding mechanism can make the pulling rope 3 move left and right, so that the lower limb swings in an arc for exercise, which is more in line with the physiological characteristics of the body.
[0023] The sliding mechanism includes two left and right rotating shafts 5 rotatably installed in the slider 1. They can rotate to reduce friction. Rubber rollers 6 for buffering are sleeved on the rotating shafts 5. They reduce friction and also reduce the noise during movement.
[0024] The support mechanism includes an inverted "U" shaped soft sling 7 installed at the end of the pulling rope 3, a rigid support plate 8 arranged at the lower end of the sling 7, and a bag 9 for installing a cold compress bag arranged inside the sling 7. The bag 9 can hold a cold compress bag.
[0025] It further includes a buffer mechanism arranged on the pulling rope 3 to slow down the impact on the slider 1. When the pulling rope 3 is released, it slows down the impact on the leg, making it more gentle. The buffer mechanism includes a rubber ball 10 installed on the pulling rope 3. The rubber ball 10 provides elastic force to achieve buffering. At the same time, it also plays a role in fixing the height of the leg. The rubber ball 10 is sleeved on the pulling rope 3, and the rubber ball 10 is located on the side of the slider 1 close to the pulling ring 4. A rigid spherical shell 11 for preventing it from passing through the slider 1 is installed on the rubber ball 10, and the end of the spherical shell 11 pointing to the slider 1 is open. The rigid spherical shell 11 can well prevent it from passing through the slider 1. Even if the rubber ball 10 breaks, there is still the spherical shell 11 for safety protection. The spherical shell 11 extends towards the direction of the pulling ring 4 to form a support sleeve 12, and a knob 13 with an inner end pressing against the pulling rope 3 is threadedly connected to the support sleeve 12 to achieve position adjustment. Due to the knob 13, the spherical shell 11 and the rubber ball 10 can slide on the pulling rope 13 to change the height of the leg.
[0026] Working principle: Pull the pull rope 3 to realize the up and down movement exercise of the legs. The setting of the rotating shaft 5 enables the slider 1 to move along the cross bar, so that the lower limbs swing in an arc and will not be pulled, which is more comfortable. For patients with lower limb fractures, during the bedridden period, in order to prevent the occurrence of complications and promote rapid recovery, it is necessary to rely on flexing and extending the hip and knee joints for in-bed functional exercises. At present, the traction bed in the orthopedic ward cannot achieve the function of lower limb functional exercise. The rubber ball 10 can play a buffering role. By adjusting the position through the knob 13, the height of the leg can be changed, which is more flexible and convenient.
[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
