Description

Technical Field

[0001] The present invention relates to the technical field of medical training, and particularly to a device for detecting and training lower limb strength of bedridden patients. Background Art

[0002] In recent years, with the acceleration of the social aging process, the number of elderly people has been steadily increasing. The aging process is accompanied by a series of physiological changes, among which the problem of falls among the elderly is becoming increasingly prominent. Falling is one of the most common accidents among the elderly, seriously affecting their health and quality of life.

[0003] Medical research shows that insufficient or unbalanced lower limb muscle strength in patients is one of the key factors leading to falls. This is particularly evident in patients with osteoporosis. When the lower limb muscle strength weakens, even a minor trip or stumble can lead to a fall. This can trigger a series of complications, including fractures, long-term bedridden state, increased risk of pneumonia, deep vein thrombosis, and even a sharp decline in overall physical function, significantly shortening the life expectancy.

[0004]

[0005] Patients who are bedridden for a long time are at particularly high risk. Due to the lack of regular physical activity, their lower limb muscles will atrophy rapidly, and the muscle strength will decrease significantly. This not only seriously hinders the subsequent rehabilitation process but also greatly increases the risk of falling when they get up or move around after getting up. In the early stage of muscle atrophy, muscle fibers gradually degenerate, reducing the ability of the muscle to generate force. As the atrophy progresses, the muscle mass decreases significantly, further weakening the supporting function of the lower limbs. Therefore, it is crucial to regularly conduct lower limb strength tests and implement appropriate training programs during the bedridden period. This helps to maintain and enhance muscle strength, thereby reducing the probability of falls when bedridden patients are preparing to get out of bed and move around.

[0006] In the context of precision medicine and personalized rehabilitation, personalized treatment plans need to be developed according to the specific conditions of each patient. These traditional assessment methods are increasingly unable to meet the requirements. There is an urgent need for more objective, accurate, and quantifiable methods to detect and train the lower limb strength of bedridden patients, so as to develop more targeted lower limb strength detection and rehabilitation training plans for different bedridden patients and ensure the safety of bedridden patients when getting out of bed and moving around.

[0007] ​In the prior art, a Chinese patent with the application number CN201721509395.3 discloses a lower limb quadriceps femoris force measuring device, which includes a support frame and a force measuring instrument. The force measuring instrument is fixedly installed on the support frame. A force application frame is connected to the conduction rod of the force measuring instrument. A connecting device is provided on the support frame, which can test the strength of the lower limb quadriceps femoris of the elderly population. It can carry out targeted lower limb muscle exercises for the elderly population according to the test results. It can be combined with a household chair to ensure that the strength of the lower limb quadriceps femoris of the elderly population is detected in a sitting position. The measurement result is accurate, and it can be separated for easy storage after measurement. In addition, the overall structure is simple and practical, easy to operate, and has a low manufacturing cost, with a relatively broad market prospect and is convenient for promotion.

[0008] Again, in the prior art, a Chinese patent with the application number CN201721509408.7 discloses a simple lower limb quadriceps femoris force measuring device, which includes a force measuring instrument. A conduction rod at one end of the force measuring instrument is connected to a fixing band, and the other end of the force measuring instrument is connected to a binding band. A fastening device is provided on the binding band. When in use, the fixing band is sleeved on the rear leg of the chair, and then the ankle is bound by the binding band and fixed by the fastening device. After binding, the calf stretches forward forcefully, tightening the binding band and the fixing band, and the force measuring instrument is used to test the strength of the lower limb quadriceps femoris. The strength of the lower limb quadriceps femoris of the elderly population can be tested through the force measuring instrument. It can be combined with a household chair to ensure that the strength of the lower limb quadriceps femoris of the elderly population is detected in a sitting position. The measurement result is accurate, and it can be separated for easy storage after measurement. In addition, the overall structure is simple and practical, easy to operate, and has a low manufacturing cost, with a relatively broad market prospect and is convenient for promotion.

[0009] Again, in the prior art, a Chinese patent with the application number CN202410291955.0 discloses a dorsiflexion exercise assistor, which includes a base and adjusting plates fixed on both sides of the base. Sliding rotary seats are fixedly installed in the middle of both sides of the base. A training plate is installed between the two sliding rotary seats. A pulling component is installed on the front side of the training plate. Elastic pulling elements are installed on both sides of the upper part of the training plate. The bottom end of the elastic pulling element is connected to an adjusting seat installed on the adjusting plate. A training plate is installed in the middle of the top of the base, and the upper part of the training plate is slidably connected to the lower part of the base through an elastic pulling element. When the elastic pulling element is located on the front side of the training plate, the front toe area presses down on the training plate, and the bottom of the training plate rotates in the opposite direction between the two sliding rotary seats to achieve dorsiflexion training; when the elastic pulling is located on the rear side of the training plate, the dorsum of the foot pulls the training plate through the pulling component, and the training plate rotates forward between the two sliding rotary seats to achieve plantar flexion movement.

[0010] Combined with the above materials, it can be known that in the prior art, a tensioner can be used to detect and train the lower limb strength of patients. However, in the actual use process, a device similar to the above is not convenient to use on a hospital bed, and patients who are bedridden for a long time are not convenient to get out of bed and move. Therefore, there will be certain inconveniences when using the device. Summary of the Invention

[0011] The purpose of the present invention is to provide a bedridden lower limb strength detection and training device to solve the problem of inconvenient use mentioned in the above background technology.

[0012] To achieve the above purpose, the present invention provides the following technical solution: A bedridden lower limb strength detection and training device includes a hospital bed board for the patient to lie on.

A buffer sponge is fixedly installed on the upper surface of the waist gasket. A fixing band pasted on the hospital bed board is fixedly installed below the waist gasket. A first restraint band for fixing the patient's waist is fixedly installed on the upper surface of the waist gasket. The waist gasket, the fixing band, and the first restraint band are all made of canvas material; An installation board is installed at the middle position outside the hospital bed board. The installation board is snap-connected to the hospital bed rear tail board through the installation buckles fixedly installed on its left and right sides. A fixing bolt is threadedly installed on the side of the installation buckle; A footrest corresponding to the patient's feet is installed on the outer surface of the installation board. A pressure sensor is fixedly installed between the footrest and the installation board. A return spring is also fixedly installed between the footrest and the installation board. A massage mechanism for massaging the patient's calf muscles is arranged below the installation board.

[0013] Preferably, a broadcast speaker and an infrared sensor are fixedly installed on the outer surface of the installation board. The infrared sensor and the broadcast speaker are connected by a wire. The position of the infrared sensor corresponds to the position of the footrest.

[0014] Preferably, the massage mechanism includes a connecting plate fixedly installed on the lower surface of the installation board. The connecting plate is horizontally arranged and there is a corresponding docking plate.

[0015] Preferably, the docking plate and the connecting plate form a detachable installation structure through a fixing plate threadedly installed above them. A support plate is rotatably installed on the upper surface of the docking plate.

[0016] Preferably, a massage roller in a cylindrical structure is fixedly installed at the top end of the support plate. The outer surface of the massage roller is in a convex structure. An extrusion spring is fixedly installed between the lower surface of the support plate and the upper surface of the docking plate.

[0017] Preferably, a connecting canvas belt is fixedly installed between the connecting plate and the waist gasket, and the connecting canvas belt is arranged in an elastic telescopic structure, and an elastic band corresponding to the patient's thigh position is arranged on the side of the connecting canvas belt.

[0018] Preferably, the elastic band is connected to the connecting canvas belt through a connecting rope on its side, and a second restraint band with a magic tape is fixedly installed on the upper surface of the elastic band.

[0019] Preferably, a recessed accommodation groove is formed at the upper end of the outer surface of the footrest, and a positioning rod is fixedly installed inside the accommodation groove, and the positioning rods are evenly distributed at equal intervals.

[0020] Preferably, a foot sleeve is arranged between the left and right footrests, and the foot sleeve is sleeved on the patient's toe position during use, and the foot sleeve is made of canvas material.

[0021] Preferably, resistance bands are fixedly installed at the left and right ends of the foot sleeve, and the resistance bands are made of elastic material, and an installation hook is fixedly installed at the top of the resistance band, and a clamping structure is formed between the installation hook and the positioning rod.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The bedridden lower limb strength detection and training device adopts a novel structural design, and the specific content is as follows:

[0023] 1. Fix the waist gasket on the middle position of the upper surface of the hospital bed board by using a fixing band, and fix the mounting plate on the outside of the hospital bed rear tail board by using a fixing buckle. Then fix the patient's waist with the first restraint band, and fix the elastic band on the patient's thigh with the second restraint band, so as to realize the wearing of the device.

[0024] Furthermore, after the device is worn, the patient's feet correspond to the footrests. Then, the patient steps on the footrests with the lower limb strength. During the stepping process, the stepping force of the patient is detected by a pressure sensor, so as to achieve the detection of the patient's strength. And a return spring provides a certain resistance to the movement of the footrest, so the patient can achieve the purpose of training the lower limb strength by continuously stepping on it.

[0025] Even further, the elastic band applies pressure to the patient's thigh position, so as to achieve the purpose of protecting the muscles during training. At the same time, the state of the footrest is detected by an infrared sensor during the movement of the footrest, so as to record the number of movements of the footrest. The number data is transmitted to the voice broadcast speaker, and the number is broadcast through the voice broadcast speaker to achieve the purpose of encouraging the patient to train.

[0026] 2. During the process of the patient stepping on the foot pedal, the lower leg moves up and down. The lower leg of the patient is used to squeeze the massage roller downward, and then under the elastic pushing action of the compression spring, the support plate together with the massage roller is reset upward. Through the up and down movement of the massage roller, the lower leg position of the patient is massaged to relax and exercise the leg muscles of the patient.

[0027] Further, the device can not only achieve stepping exercises to strengthen the lower limbs, but also exercise the foot strength of the patient through the foot sleeve. The foot sleeve is installed by the engagement between the installation hook and the positioning rod (at this time, the installation mechanism is removed from the connecting plate). After the patient puts the foot sleeve on the toe position, training is achieved by bending forward and backward. According to different training needs, the installation hook is matched with the positioning rods at different positions to adjust the elasticity of the resistance band.

A footrest 8 corresponding to the patient's feet is installed on the outer surface of the installation board 6, a pressure sensor 9 is fixedly installed between the footrest 8 and the installation board 6, and a return spring 10 is also fixedly installed between the footrest 8 and the installation board 6. A broadcast speaker 12 and an infrared sensor 11 are fixedly installed on the outer surface of the installation board 6, and the infrared sensor 11 is connected to the broadcast speaker 12 by a wire, and the position of the infrared sensor 11 corresponds to the position of the footrest 8. A connecting canvas belt 19 is fixedly installed between the connecting plate 13 and the waist pad 3, and the connecting canvas belt 19 is set to be an elastic telescopic structure, and an elastic band 20 corresponding to the patient's thigh position is arranged on the side of the connecting canvas belt 19. The elastic band 20 is connected to the connecting canvas belt 19 through a connecting rope 21 on its side, and a second restraint band 22 with a magic tape is fixedly installed on the upper surface of the elastic band 20.

[0041] When using the device, first place the waist pad 3 at the middle position above the hospital bed board 1, and then wrap the fixing band 4 below the waist pad 3 around the lower part of the hospital bed board 1 and fix it with a magic tape to achieve the fixing effect of the waist pad 3. Then, the patient lies on the hospital bed board 1 and uses the first restraint band 5 above the waist pad 3 to fix the patient's waist. At the same time, use the installation buckle 7 and the fixing bolt 701 to fix the installation board 6 outside the rear end board 2 of the hospital bed (the waist pad 3 and the installation board 6 are connected by a connecting canvas belt 19). Then, the patient uses the lower limb strength to step on the footrest 8 with the feet. During the process of stepping on the footrest 8, the footrest 8 squeezes the pressure sensor 9, and the pressure sensor 9 records the stepping force data, so as to detect the patient's lower limb strength (the footrest 8 is then pushed back by the return spring 10, and the patient reaches the training purpose through multiple steps and the elastic effect of the return spring 10). During the movement of the footrest 8, the infrared sensor 11 detects its state, so as to record the number of steps.

[0042] Before detection or training, the elastic band 20 connected to the side of the canvas belt 19 is fixed to the patient's thigh position by the second restraint band 22, so as to apply pressure to the patient's muscles by the elastic band 20, thereby protecting the patient's thigh muscles during storage.

[0043] Embodiment 2: Please refer to Figures 4-6 , in order to achieve the purpose of massaging the patient's calf position in this embodiment, the following technical solutions are provided, and specifically disclosed: a massage mechanism for massaging the patient's calf muscles is provided below the mounting plate 6. The massage mechanism includes a connecting plate 13 fixedly installed on the lower surface of the mounting plate 6, and the connecting plate 13 is horizontally arranged. And the connecting plate 13 is provided with a corresponding docking plate 14. The docking plate 14 and the connecting plate 13 form a detachable mounting structure through a fixing plate 15 threadedly installed above them. And a support plate 16 is rotatably installed on the upper surface of the docking plate 14. The top of the support plate 16 is fixedly installed with a massage roller 17 in a cylindrical structure, and the outer surface of the massage roller 17 is provided with a convex structure. And a compression spring 18 is fixedly installed between the lower surface of the support plate 16 and the upper surface of the docking plate 14.

[0044] During training, according to the patient's needs, such as when the patient's leg muscles are weak, the docking plate 14 is fixedly installed on the side of the connecting plate 13 by using the fixing plate 15 and bolts to realize the installation of the massage mechanism. Then, when using the device, when the patient kicks, the calf position will squeeze the massage roller 17 downward. Then, when the patient retracts the leg, under the elastic pushing action of the compression spring 18, the support plate 16 is pushed to rotate upward, thereby changing the position of the massage roller 17. Thus, the patient's calf muscles are massaged by the up and down movement of the massage roller 17 to achieve the purpose of relaxing the muscles.

[0045] Embodiment 3: Please refer to Figures 8-10 , in order to achieve the purpose of training the patient's foot strength in this embodiment, the following technical solutions are provided, and specifically disclosed: an inwardly concave accommodation groove 23 is opened at the upper end of the outer surface of the foot pedal 8, and a positioning rod 24 is fixedly installed inside the accommodation groove 23, and the positioning rods 24 are evenly distributed at equal intervals. A foot sleeve 25 is arranged between the left and right foot pedals 8. And the foot sleeve 25 is sleeved on the patient's toe position during use. And the foot sleeve 25 is made of canvas material. The left and right ends of the foot sleeve 25 are fixedly installed with resistance bands 26, and the resistance bands 26 are made of elastic material. And the top of the resistance band 26 is fixedly installed with a mounting hook 27. The mounting hook 27 and the positioning rod 24 form a clamping structure.

[0046] When foot strength training (i.e., dorsiflexion training) of a patient is required, first remove the docking plate 14, and then snap the mounting hooks 27 on both the left and right sides of the foot sleeve 25 onto the positioning rods 24 inside the receiving groove 23 (the mounting hooks 27 are matched with the positioning rods 24 at different positions according to actual training needs, so as to change the elastic resistance of the resistance band 26). Then put the foot sleeve 25 on the patient's toe position, and the patient performs dorsiflexion operation, using the resistance band 26 to provide resistance to achieve the training purpose.
