Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical appliances, and specifically relates to a bedridden exercise device for orthopedic patients. Background Art
[0002] After orthopedic lower limb surgery, patients need to lie in bed with the affected limb elevated and immobilized in a long-term position. Immobilizing the joint in the functional position is beneficial to functional recovery. For the ankle joint, the optimal functional position of the foot is 90° flexion. In order to fix the foot in the functional position, the skin of the heel and the medial and lateral malleoli is subjected to external vertical pressure, friction, and shear force for a long time, and there is a lack of protection of muscle and fat tissues at the heel and the medial and lateral malleoli, resulting in poor blood circulation and easy skin pressure injury.
[0003] Deep vein thrombosis is a common disease in vascular surgery and belongs to the category of thrombus diseases. The main affected part is the lower limb. For patients with deep vein thrombosis, the main clinical manifestations are sudden swelling and pain in one limb, affecting walking and daily living ability. When deep vein thrombosis metastasizes to the lungs and forms pulmonary embolism, patients will experience dyspnea, chest pain, hemoptysis, syncope, and even death.
[0004] Orthopedic postoperative rehabilitation exercises can prevent deep vein thrombosis. Common orthopedic postoperative rehabilitation exercise methods include: ankle joint movement, quadriceps femoris contraction exercise, knee and hip flexion exercise, and straight leg elevation exercise.
[0005] The deficiencies of the above technologies are as follows:
[0006] First, currently in clinical practice, a pillow is commonly placed under the patient's calf to keep the heel suspended and prevent pressure injury to the heel. However, due to factors such as patient restlessness and poor pillow support, it is difficult for the heel to remain suspended for a long time, resulting in pressure injury.
[0007] Second, in postoperative rehabilitation exercises, there is a lack of effective auxiliary equipment, which requires the guidance and assistance of medical staff, increasing the workload of medical staff and with poor rehabilitation exercise effects. Content of the Utility Model
[0008] The purpose of the utility model is to provide a bedridden exercise device for orthopedic patients. By placing the leg plate and leg pad to elevate the affected limb of the patient, long-term immobilization of the affected limb in a raised position in bed is achieved, making the patient's foot suspended and in a neutral position, avoiding pressure injury to the patient's heel; it can also play a bedridden exercise video through the controller touch screen to guide the patient to complete rehabilitation exercises, reducing the workload of medical staff, and ensuring the accuracy of movements through the warning light to improve the rehabilitation exercise effect.
[0009] In order to achieve the above invention purpose, the utility model adopts the following technical solutions:
[0010] An orthopedic patient bedridden exercise device, comprising a bottom plate and a controller. A leg placement plate and an empty slot are provided on the top of the bottom plate. A vertical plate is provided at the empty slot, and a leg pad is provided on the leg placement plate. A pedal that can be vertically flipped is connected to one side of the vertical plate close to the leg placement plate. A rotating shaft is provided at the flipping connection of the pedal, and a torsion spring is provided on the rotating shaft. A pressure sensor is provided between the pedal and the vertical plate, and the pressure sensor is arranged below the rotating shaft. When the torsion spring resets, the pedal is in a vertical placement state, and there is a spacing between the pedal and the pressure sensor. A warning light and a touch screen are provided on the front of the controller, and the touch screen can play bedridden exercise videos. The warning light and the pressure sensor are wirelessly connected via Bluetooth: when the pedal is stepped on, the lower edge of the pedal flips towards the vertical plate and touches the pressure sensor, triggering the warning light to turn on, and the torsion spring is twisted; when the pedal is released, the torsion spring resets to drive the pedal to flip back and leave the pressure sensor, triggering the warning light to turn off.
[0011] Compared with the prior art, the orthopedic patient bedridden exercise device adopting the above technical solution has the following beneficial effects:
[0012] I. For the orthopedic patient bedridden exercise device of the present utility model, after orthopedic lower limb surgery, the patient's leg is placed on the leg placement plate and the calf is elevated by the leg pad. The patient's heel is suspended at the empty slot and the sole of the foot is pressed against the surface of the pedal, so that the patient's foot is in a neutral position. At the same time, it avoids pressure injury to the patient's heel, realizes long-term body position braking of elevating the affected limb while lying in bed, and braking the joint in the functional position is beneficial to functional recovery.
[0013] II. By playing bedridden exercise videos on the touch screen, allowing the patient to learn the actions demonstrated in the videos, achieving the purpose of guiding the patient to complete rehabilitation exercises and reducing the workload of medical staff. The method of quadriceps femoris contraction exercise: elevate the patient's calf by the leg pad. The patient needs to tighten the thigh muscles, press the pedal forcefully with the heel, and straighten the knee joint. After maintaining for 5 seconds, relax the muscles and release the pedal, thus completing one action of quadriceps femoris contraction exercise. The pressure sensor senses the patient's stepping on the pedal situation and is displayed through the warning light, ensuring that the patient's heel effectively presses the pedal and improving the rehabilitation exercise effect.
[0014] Preferably, the leg pad adopts an airbag with adjustable height. An inflation port is provided outside the leg pad, and an inflation balloon is connected to the inflation port. The inflation balloon is provided with a deflation valve. The inflation balloon can refer to the inflation balloon of the existing medical blood pressure cuff. Inject air into the inflation port by squeezing the inflation balloon, and deflate the inflation port by opening the deflation valve. Medical staff can adjust the height of the leg pad according to needs to improve the patient's comfort.
[0015] Preferably, the leg placing board is pivotally connected to the bottom board at one end away from the empty slot. A push rod motor is provided between the leg placing board and the bottom board. The leg placing board is driven by the push rod motor to perform a vertical flip. The touch screen is wirelessly connected to the push rod motor via Bluetooth. For reference, please refer to the existing Haier foot massager. The leg placing board can be flipped by connecting to the touch screen APP via Bluetooth. Method for straight leg raising exercise: The patient needs to tighten the thigh muscles, straighten the knee joint, and raise the patient's foot 15 cm by flipping up the leg placing board. After holding for 5 s, relax the muscles and flip down the leg placing board to return the patient's leg to the original position, thus completing one action of the straight leg raising exercise. There is no need for medical staff to help the patient with straight leg raising, reducing the workload of medical staff. Moreover, the height at which the leg placing board raises the patient's leg is relatively accurate, and the rehabilitation exercise effect is better.
[0016] Preferably, a rotatable cross bar is provided in the empty slot. The length direction of the cross bar is the same as the length direction of the bottom board, and the cross bar is threadedly connected to the vertical board. Medical staff can adjust the distance between the vertical board and the leg board according to needs. When performing quadriceps contraction exercises, rotate the cross bar forward to shorten the distance between the vertical board and the leg placing board until the patient's sole touches the pedal, which is suitable for patients with different leg lengths. When performing ankle joint movements, rotate the cross bar backward to increase the distance between the vertical board and the leg placing board until the pedal is far from the patient's foot, allowing the patient's foot to dorsiflex, plantarflex, internally rotate, and externally rotate without obstruction.
[0017] Preferably, the number of leg placing boards on the bottom board is two, and the two leg placing boards are horizontally symmetrically arranged. The number of pedals is the same as the number of leg placing boards and is correspondingly arranged. The patient's two legs are respectively placed on the two leg placing boards, and one side of the leg can be selected for postoperative rehabilitation exercise according to needs. The patient's two legs can take turns for postoperative rehabilitation exercise.
[0018] Preferably, a wristband is provided on the back of the controller. The wristband is wound around the patient's wrist and fixed by Velcro. Wearing the controller on the patient's wrist via the wristband can prevent the controller from being accidentally lost.
[0019] Preferably, convex walls are respectively provided on both sides of the leg placing board. A groove is formed between the two convex walls, and the leg pad is arranged in the groove. The patient's calf is placed on the leg pad and limited in the groove. The groove plays a role in limiting the patient's leg to prevent the patient's leg from accidentally detaching from the leg placing board.
[0020] Preferably, straps and buckles are respectively provided on the convex walls on both sides of the leg placement board. The movable end of the strap passes through the buckle and is fixed by sticking with Velcro. Microelectric contacts are also provided on the upper surface of the leg placement board. The microelectric contacts are wirelessly connected to the touch screen via Bluetooth. The touch screen APP is connected via Bluetooth to control the microelectric contacts to release current. The microelectric contacts can refer to existing low-frequency pulse massagers (manufacturer: Shenzhen Lefukang Technology Co., Ltd.). When the low-frequency current causes muscle contraction or relaxation, the pumping action of the muscles starts to work. When the muscles relax, a large amount of blood is input. When they contract, the blood containing metabolites is sent out. This operation cycle repeats, which can help the blood run smoothly and the blood circulation be unobstructed. The fixation of the patient's legs is enhanced through the straps to prevent the patient's legs from accidentally slipping out of the groove. By releasing current through the microelectric contacts, the effect of stimulating the vitality of nerve cells to relieve muscle pain can be achieved. Description of the Drawings

Detailed Description of the Invention
[0030] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects according to the present utility model as follows.
[0031] Embodiment 1
[0032] As Figures 1 to 7 shown, the orthopedic patient bedridden exercise device includes a bottom plate 1 and a controller 4. A leg placement plate 12 and an empty slot 15 are provided on the bottom plate 1. A vertical plate 2 is provided at the empty slot 15, and a leg pad 3 is provided on the leg placement plate 12. On the side of the vertical plate 2 close to the leg placement plate 12, there is a pedal 23 that can be vertically flipped. A rotating shaft 24 is provided at the flipping connection of the pedal 23, and a torsion spring is provided on the rotating shaft 24. A pressure sensor 22 is provided between the pedal 23 and the vertical plate 2, and the pressure sensor 22 is provided below the rotating shaft 24. When the torsion spring resets, the pedal 23 is in a vertical placement state, and there is a spacing between the pedal 23 and the pressure sensor 22. A warning light 42 and a touch screen 40 are provided on the front of the controller 4, and the touch screen 40 can play bedridden exercise videos. The warning light 42 and the pressure sensor 22 are wirelessly connected via Bluetooth: when the pedal 23 is stepped on, the lower edge of the pedal 23 flips towards the vertical plate 2 and contacts the pressure sensor 22, triggering the warning light 42 to light up, and the torsion spring is twisted; when the pedal 23 is released, the torsion spring resets and drives the pedal 23 to flip back and leave the pressure sensor 22, triggering the warning light 42 to turn off. After orthopedic lower limb surgery, the patient's leg is placed on the leg placement plate 12 and the lower leg is elevated by the leg pad 3. The patient's heel is suspended at the empty slot 15 and the sole of the foot is pressed against the surface of the pedal 23, keeping the patient's foot in a neutral position, while avoiding pressure injuries to the patient's heel, achieving long-term body position immobilization of the elevated affected limb in bed, and immobilizing the joint in the functional position is beneficial to functional recovery.
[0033] Among them, there are bedridden exercise videos of ankle joint movement, quadriceps muscle contraction exercise, and straight leg raise exercise in the touch screen 40 APP. The patient opens the APP to play the video and learns the actions demonstrated in the video, achieving the purpose of guiding the patient to complete rehabilitation exercises and reducing the workload of medical staff.
[0034] Among them, the method of quadriceps muscle contraction exercise: elevate the patient's lower leg through the leg pad 3. The patient needs to tighten the thigh muscles, press the pedal 23 forcefully with the heel, and straighten the knee joint. After maintaining for 5 s, relax the muscles and release the pedal 23, thus completing one action of quadriceps muscle contraction exercise. The pressure sensor 22 senses the situation of the patient stepping on the pedal 23, and through the display of the warning light 42, it is ensured that the patient's heel effectively presses the pedal 23, improving the rehabilitation exercise effect.
[0035] Referring to Figure 1 and Figure 5, the leg pad 3 adopts an airbag with adjustable height. There is an inflation port 30 outside the leg pad 3. The inflation port 30 is connected to an inflation balloon 31. The inflation balloon 31 is provided with a deflation valve 32. The inflation balloon 31 can refer to the existing inflation balloon of a medical blood pressure cuff. By squeezing the inflation balloon 31, the inflation port 30 is inflated, and by opening the deflation valve 32, the inflation port 30 is deflated. Medical staff can adjust the height of the leg pad 3 according to needs to improve the comfort of patients.
[0036] Refer to Figure 5 and Figure 6 , at one end of the leg plate 12 away from the empty slot 15, it is rotatably connected to the bottom plate 1. There is a jacking motor 13 between the leg plate 12 and the bottom plate 1. The leg plate 12 is driven by the jacking motor 13 to perform a vertical flip. The touch screen 40 and the jacking motor 13 are wirelessly connected via Bluetooth. It can refer to the existing Haier foot massager, and the flip of the leg plate 12 is controlled through the Bluetooth connection of the touch screen 40 to the APP. Straight leg raising exercise method: The patient needs to tighten the thigh muscles, straighten the knee joint, and raise the patient's foot 15 cm through the upward flip of the leg plate 12. After holding for 5 s, relax the muscles, and then lower the patient's leg back to the original position through the downward flip of the leg plate 12, thus completing the action of a straight leg raising exercise. It does not require medical staff to help the patient with straight leg raising, reducing the workload of medical staff; moreover, the height of the patient's leg raised by the leg plate 12 is relatively accurate, and the rehabilitation exercise effect is better.
[0037] Refer to Figure 2 , there is a rotatable cross bar 21 in the empty slot 15. The length direction of the cross bar 21 is the same as the length direction of the bottom plate 1. The cross bar 21 is threadedly connected to the vertical plate 2. Medical staff can adjust the distance between the vertical plate 2 and the leg plate according to needs. When performing quadriceps contraction exercises, by rotating the cross bar 21 forward, the distance between the vertical plate 2 and the leg plate 12 is shortened until the patient's sole touches the pedal 23, suitable for different patient leg lengths; when performing ankle joint movements, by rotating the cross bar 21 backward, the distance between the vertical plate 2 and the leg plate 12 is increased until the pedal 23 is away from the patient's foot, so that the dorsiflexion, plantar flexion, internal rotation, and external rotation of the patient's foot are not blocked.
[0038] Among them, there is a rotatable knob 25 on the outside of the bottom plate 1. The knob 25 is fixed to the end of the cross bar 21. The outer peripheral surface of the knob 25 is provided with anti-slip lines, and the anti-slip lines are used to increase friction. Medical staff drive the rotation of the rotating shaft 24 by rotating the knob 25, and the operation is simple.
[0039] Refer to Figure 1 , the number of leg plates 12 on the bottom plate 1 is two. The two leg plates 12 are horizontally symmetrically arranged. The number of pedals 23 is the same as the number of leg plates 12 and is arranged in corresponding positions. The patient's two legs are respectively placed on the two leg plates 12. One side of the leg can be selected for postoperative rehabilitation exercise according to needs, and the patient's two legs can take turns for postoperative rehabilitation exercise.
[0040] Among them, a wrist strap 43 is provided on the back of the controller 4. The wrist strap 43 is wound around the patient's wrist and fixed by Velcro. Wearing the controller 4 on the patient's wrist through the wrist strap 43 can prevent the controller 4 from being accidentally lost.
[0041] Among them, convex walls are respectively provided on both sides of the upper surface of the leg rest plate 12. A groove 14 is formed between the two convex walls. The leg pad 3 is arranged in the groove 14. The patient's calf is placed on the leg pad 3 and limited in the groove 14. The groove 14 plays a role in limiting the patient's leg and preventing the patient's leg from accidentally detaching from the leg rest plate 12.
[0042] Among them, an elastic hip pad 11 is further provided on the bottom plate 1. The patient's buttocks are placed on the hip pad 11.
[0043] Embodiment 2
[0044] As Figure 8 shown in the orthopedic patient's in-bed exercise device. This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that:
[0045] Binding straps 5 and buckle 51 are respectively provided on the convex walls on both sides of the leg rest plate 12. The movable end of the binding strap 5 passes through the buckle 51 and is fixed by Velcro. A microelectric contact 52 is also provided on the upper surface of the leg rest plate 12. The microelectric contact 52 is wirelessly connected to the touch screen 40 via Bluetooth. The touch screen 40 of the APP controls the microelectric contact 52 to release current through Bluetooth connection. The microelectric contact 52 can refer to the existing low-frequency pulse massager (manufacturer: Shenzhen Lefukang Technology Co., Ltd.). When the low-frequency current causes muscle contraction or relaxation, the pumping action of the muscle starts to work. When it relaxes, a large amount of blood is input. When it contracts, the blood containing metabolites is sent out. This operation cycle repeats, which can help the blood flow smoothly and the blood circulation be unobstructed. Strengthening the fixation of the patient's leg through the binding strap 5 can prevent the patient's leg from accidentally detaching from the groove 14. Releasing current through the microelectric contact 52 can achieve the effect of stimulating the vitality of nerve cells to relieve muscle pain; when performing quadriceps contraction exercises and straight leg raising exercises, the current stimulation of the microelectric contact 52 can help the patient tighten the thigh muscles.
