Description

Technical Field

[0001] The present invention relates to the technical field of traction devices, and particularly to an anti-fall traction device for the rehabilitation exercise of sarcopenia patients. Background Art

[0002] With the aggravation of population aging, the number of sarcopenia patients has been increasing year by year. Sarcopenia can lead to weakened muscle strength and decreased body balance ability of patients, which are extremely likely to cause accidents such as falls, seriously affecting the quality of life and health safety of patients. At present, in the rehabilitation treatment of sarcopenia patients, rehabilitation exercise is an important means to improve muscle function and enhance body coordination. However, the existing rehabilitation exercise traction devices generally have the problem of single function. Most devices can only achieve single training of the upper or lower limbs, and cannot meet the needs of patients for coordinated rehabilitation training of the upper and lower limbs at the same time, making it difficult to achieve an ideal rehabilitation effect. In addition, some devices are complex to operate and require long-term assistance from professional medical staff, increasing the nursing cost and operation difficulty, and it is difficult for patients and their families to use them independently; there are also some devices that do not fully consider the comfort and safety of patients during the rehabilitation process, lacking necessary protective measures and auxiliary functions, such as the lack of effective anti-fall protection, the absence of massage and physical therapy structures, and the inability to adapt to patients of different body types. As a result, patients are prone to discomfort during the rehabilitation training process, and there are even potential safety hazards, limiting the actual application effect of the rehabilitation device.

[0016] Please refer to Figure 1-8 , the present invention provides a fall prevention traction device for the rehabilitation exercise of patients with sarcopenia, including two lower limb carrying auxiliary support seats 1, two support brackets 13 and a rear support seat 12. The two lower limb carrying auxiliary support seats 1 are both arranged between the two support brackets 13. The rear ends of the two lower limb carrying auxiliary support seats 1 are respectively arranged at the left and right ends of the front side of the rear support seat 12. On the two support brackets 13, movable track grooves 14 are arranged at the upper and lower parts close to the two lower limb carrying auxiliary support seats 1. On the two support brackets 13, at the upper parts close to the two movable track grooves 14, there are arranged board movable grooves 16. At the rear ends of the bottoms of the two lower limb carrying auxiliary support seats 1, bottom fixed support columns 3 are installed. In the middle of the two bottom fixed support columns 3, movable support rods 2 are rotatably connected. The two movable support rods 2 are respectively installed at the rear parts of the inner sides of the corresponding support brackets 13. At the lower parts of the middle front sides of the two lower limb carrying auxiliary support seats 1, connecting movable fixed rods 4 penetrate through. On the mutually remote sides of the two connecting movable fixed rods 4, two connecting clamping plates one 5 are installed. The two connecting movable fixed rods 4 are respectively slidably connected with the corresponding movable track grooves 14. At the tops of the multiple connecting clamping plates one 5, there are fixedly connected connecting rope belts 6. The two connecting rope belts 6 in a group respectively penetrate through the corresponding boards 17 and are connected with rotating wheels 7, and are fixedly connected with connecting clamping plates two 8. On the two connecting clamping plates two 8 in a group, there are installed fixed rods 9. At the outer ends of the two fixed rods 9, DC motors 10 are installed. In the middle of the two rotating wheels 7 in a group, there are installed wheel rods 15. The two wheel rods 15 are respectively erected on the corresponding support brackets 13. The two boards 17 are respectively slidably connected with the corresponding board movable grooves 16. At the upper and lower parts of the rear sides of the two boards 17, wrist support belts 20 and finger support belts 21 are respectively installed. At the front sides of the bottoms of the two boards 17, they are respectively fixedly connected with one ends of the corresponding lower protection belts 19. The other ends of the two lower protection belts 19 are respectively fixedly connected with the front sides of the bottoms of the corresponding upper limb elbow brackets 18. The two upper limb elbow brackets 18 shown are respectively installed at the upper parts of the inner sides of the corresponding support brackets 13 and located at the rear support seat 12. In the middle of the rear support seat 12, there are arranged a right seat 30 and a left seat 31. At the front ends of the two lower limb carrying auxiliary support seats 1, foot support seats 22 are installed. At the upper parts of the inner sides of the two support brackets 13 and located above the lower protection belts 19, control buttons 29 are installed. The two control buttons 29 are respectively electrically connected with the corresponding DC motors 10, and the two DC motors 10 are electrically connected; Overall architecture coordination foundation: The traction device uses two support brackets 13 as the main support framework to build the mechanical structure foundation of the entire device. Two lower limb mounting auxiliary supports 1 are horizontally arranged between the support brackets and are firmly connected at the rear end through a rear support 12 to form a platform for the patient to place the lower limbs. The rear support 12 not only serves to connect the lower limb mounting auxiliary supports but also provides a support area for the patient's back and buttocks. The right seat 30 and left seat 31 provided inside it can meet the sitting posture needs of the patient. Lower limb movement drive mechanism: The patient places the lower limbs steadily on the lower limb mounting auxiliary support 1, and the feet are placed on the front foot rest 22. When lower limb rehabilitation exercises are required, the operator presses the control button 29 inside the support bracket 13. The control button 29, as a signal transmission hub, converts the operation instruction into an electrical signal and transmits it to the DC motor 10 electrically connected to it. After receiving the electrical signal, the stator and rotor inside the DC motor 10 start to rotate at high speed under the action of electromagnetic force. The rotation of the DC motor 10 is transmitted to the connecting splint II 8 through the fixed rod 9, driving the connecting splint II 8 to generate a linear displacement. Since the connecting splint II 8 is connected to the connecting splint I 5 through the connecting rope 6, under the guiding action of the rotating wheel 7, the pulling force of the connecting splint II 8 is transmitted to the connecting splint I 5 through the connecting rope 6. The connecting splint I 5 is fixedly connected to the connecting movable fixed rod 4, and then the connecting movable fixed rod 4 is pulled to slide horizontally in the movable track groove 14 on the support bracket 13. The sliding of the connecting movable fixed rod 4 drives the connected lower limb mounting auxiliary support 1 to generate a horizontal displacement, simulating the flexion, extension, translation and other movements of the human lower limbs, so as to realize the rehabilitation training of the patient's lower limb muscles and joints. In this process, the rotating structure composed of the bottom fixed support column 3 and the movable support rod 2 at the bottom of the lower limb mounting auxiliary support 1 can flexibly rotate within a certain angle range according to the movement track of the lower limb mounting auxiliary support 1, playing a role in auxiliary support and balance adjustment to ensure the stability and safety of the lower limb movement. Upper limb movement linkage process: The patient holds the boarding plate 17 with both hands, and the boarding plate 17 is embedded in the boarding plate movable groove 16 at the upper part of the support bracket 13. When the DC motor 10 drives the connecting rope 6 to move, while pulling the connecting splint I 5, the connecting rope 6 will also generate an upward or backward pulling force on the boarding plate 17 through the rotating wheel 7. Since the boarding plate 17 is connected to the lower guard belt 19, and the other end of the lower guard belt 19 is fixed on the upper limb elbow support 18, this connection method causes the boarding plate 17 to slide in the boarding plate movable groove 16. When the patient holds the boarding plate 17, the upper limb muscles need to actively exert force to maintain the grip force and control the movement direction of the boarding plate 17, and at the same time cooperate with the movement rhythm of the lower limbs to realize the flexion, extension, stretching and other movements of the upper limbs. The wrist support belt 20 and finger support belt 21 provide additional fixation and support for the patient's hands, helping the patient to exert force better and control the upper limb movement, so as to realize the coordinated rehabilitation training of the upper and lower limbs.Through this ingenious mechanical structure design, only one DC motor is needed as the power source to simultaneously drive the upper and lower limbs for rehabilitation exercises, simplifying the operation process of the device and reducing the complexity and manufacturing cost of the device.

[0017] On the middle and rear sides of both lower limbs carrying the auxiliary support seat 1, there are protective fastening belts 28 installed. On both sides of the connecting movable fixing rods 4 corresponding to the lower limbs carrying the auxiliary support seat 1, there are protective side clips 27 installed. On the rear side of the top of both lower limbs carrying the auxiliary support seat 1, there are evenly distributed massage convex balls 23, and on the front side of the top of both lower limbs carrying the auxiliary support seat 1, there are evenly distributed massage convex strips 25. Safety guarantee of the protective fastening belt: After the patient places the lower limbs on the lower limbs carrying the auxiliary support seat 1, first use the protective fastening belt 28 to fix the lower limbs. The protective fastening belt 28 usually adopts a design with adjustable length. The patient or caregiver can adjust the fastening according to the thickness of the patient's lower limbs by means of buckles, Velcro, etc. The protective fastening belt 28 closely adheres to the thigh or calf part of the patient's lower limbs. During the rehabilitation exercise process, it can effectively limit the lateral and longitudinal displacement of the lower limbs, preventing the patient from slipping off the lower limbs carrying the auxiliary support seat 1 due to excessive movement amplitude or loss of balance, providing the first safety protection barrier for the patient's lower limb movement. Auxiliary protection of the protective side clip: The protective side clip 27 installed on the connecting movable fixing rod 4 is located on both sides of the lower limbs carrying the auxiliary support seat 1. Its shape and structure are designed according to the contour of the human lower limbs and are usually made of a soft and elastic material. During the rehabilitation exercise process, when the patient's lower limbs sway left and right or are accidentally collided, the protective side clip 27 can buffer the impact force through its own elasticity, reduce the impact force received by the lower limbs, and at the same time play a lateral support and restraint role on the lower limbs, further ensuring the safety and stability of the patient's lower limbs during the movement process, forming a double protection system with the protective fastening belt 28. Physiotherapy effect of the massage convex ball and the massage convex strip: When the patient performs rehabilitation exercises, the lower limbs continuously contact the massage convex balls 23 and massage convex strips 25 on the top of the lower limbs carrying the auxiliary support seat 1. The massage convex balls 23 are hemispherical protrusions distributed on the rear side of the top of the lower limbs carrying the auxiliary support seat 1. During the placement and movement of the patient's lower limbs, they can perform point-like pressing and stimulation on the muscles and acupoints of the lower limbs; the massage convex strips 25 are strip-shaped protrusions distributed on the front side of the top of the lower limbs carrying the auxiliary support seat 1, mainly performing linear massage and stretching on the lower limb muscles. As the patient's lower limbs move, relative friction and extrusion are generated between the massage convex balls 23 and massage convex strips 25 and the lower limb muscles. This physical stimulation can promote local blood circulation in the lower limbs, accelerate metabolism, relieve muscle fatigue, and at the same time stimulate nerve endings, enhance the perception and reaction ability of the muscles, combining rehabilitation training with physical therapy to improve the rehabilitation effect.

[0018] There are rotatably connected bracket frames 11 at the rear sides of both lower limb carrying auxiliary support seats 1. The two bracket frames 11 are respectively installed at the left and right ends of the front side of the rear support seat 12. A connecting seat support rod 32 is installed in the middle of the left seat 31. An inner support rod 33 is slidably connected to the middle of the connecting seat support rod 32. The right end of the inner support rod 33 is clamped to the output end of the electric telescopic rod 34. The electric telescopic rod 34 is installed inside the right seat 30; Connection and adjustment of the bracket frame: The bracket frame 11 at the rear side of the lower limb carrying auxiliary support seat 1 is connected to the lower limb carrying auxiliary support seat 1 and the rear support seat 12 through a rotating shaft, forming a rotatable connection structure. During the assembly and use of the device, the bracket frame 11 can rotate within a certain angle range around the rotating shaft. This rotational characteristic enables the lower limb carrying auxiliary support seat 1 to be adjusted in angle according to the actual needs of the patient and the usage scenario during installation. For example, when the patient needs a more comfortable lower limb placement angle, the caregiver can manually adjust the angle of the bracket frame 11 to tilt the lower limb carrying auxiliary support seat 1 at a certain angle to provide a more fitting support for the patient. At the same time, the bracket frame 11 can be locked in a suitable position through its own structure after rotation, ensuring that the lower limb carrying auxiliary support seat 1 remains stable during the rehabilitation exercise and will not shift in angle due to the movement of the patient's lower limbs. Adjustment of the seat spacing by the electric telescopic rod: The right seat 30 and the left seat 31 in the middle of the rear support seat 12 are connected through the connecting seat support rod 32 and the inner support rod 33. The electric telescopic rod 34 is installed inside the right seat 30, and its output end is connected to the right end of the inner support rod 33 in a clamping manner. When the patient sits on the right seat 30 and the left seat 31, if the seat spacing is inappropriate, the operator can start the electric telescopic rod 34 through the control switch. The motor inside the electric telescopic rod 34 drives the screw rod to rotate. The screw nut generates a linear displacement under the rotation of the screw rod, thereby driving the inner support rod 33 to perform telescopic movement inside the connecting seat support rod 32. The telescopic movement of the inner support rod 33 changes the distance between the right seat 30 and the left seat 31, and can adapt to the hip width requirements of patients with different body types. After the adjustment is completed, the electric telescopic rod 34 can maintain the current telescopic state, providing a stable and comfortable sitting posture support for the patient, and avoiding discomfort or affecting the training effect of the patient during the rehabilitation training due to improper seat spacing.

[0019] The two lower limbs carrying auxiliary support seats 1 have staggered massage convex balls 23 on the top and back sides and are evenly distributed with through holes 1 24, and the two lower limbs carrying auxiliary support seats 1 have staggered massage convex strips 25 on the top and front sides and are evenly distributed with through holes 2 26; the ventilation function of the through holes is realized: while the massage convex balls 23 on the back side and the massage convex strips 25 on the front side of the lower limb carrying auxiliary support seat 1 provide massage therapy for the patient's lower limbs, due to the long-term close contact between the patient's lower limbs and these convex structures, it is easy to cause local heat accumulation and sweat cannot be discharged in time. The through holes 1 24 and the through holes 2 26 set on the top of the lower limb carrying auxiliary support seat 1 can effectively solve this problem. The through holes 1 24 are evenly distributed between the massage convex balls 23, and the through holes 2 26 are evenly distributed between the massage convex strips 25, and these through holes are connected to the outside air. When the patient performs rehabilitation exercises, the relative movement between the lower limbs and the lower limb carrying auxiliary support seat 1 and the natural breathing of the human body will form air flow around the through holes. The air enters the gap between the lower limb and the lower limb auxiliary support 1 through the through hole 1 24 and the through hole 2 26, taking away the accumulated heat and sweat, so that the area can maintain air circulation, thereby effectively reducing the stuffiness of the patient's lower limbs and keeping the skin dry and comfortable. This breathable design not only improves the patient's experience during rehabilitation training, but also prevents skin problems caused by a humid environment, such as rashes and itching, and provides a healthier environment for the patient's rehabilitation training.

[0020] Two rear supports 35 are arranged on the rear side between the two support frames 13, located behind the right seat 30 and the left seat 31, and the middle parts of the two rear supports 35 are slidably connected with a connecting plate 42; Back support of the rear support: The two rear supports 35 are installed on the rear side between the two support frames 13, located behind the right seat 30 and the left seat 31, and their shapes and heights are designed according to the physiological curve of the human back, and are made of soft materials with certain support strength, such as sponge, memory foam, etc. When the patient sits on the rear support seat 12 for rehabilitation training, the back naturally leans on the rear support 35, and the rear support 35 can provide a large area of ​​support for the patient's entire back, share the pressure of the back muscles, and relieve back fatigue. The soft material of the rear support 35 can fit the contour of the patient's back, reduce the discomfort caused by hard contact, and create a comfortable back support environment for the patient.

[0021] A base plate 36 is installed at the bottom of the two guard frames 13, and a plurality of universal wheels 37 are equidistantly installed at the bottom of the two base plates 36 and the connecting plate 42; the universal wheels 37 at the bottom of the base plate 36 and the connecting plate 42 make the entire traction device easy to move, which is convenient for medical staff to move the device to different locations to meet the needs of different usage scenarios, such as wards, rehabilitation training rooms, etc., and also convenient for patients to perform rehabilitation training in different areas.

[0022] On each of the two fixed rods 9, a first support frame 38 is erected. On each of the two DC motors 10, a motor support frame 40 is provided. On each of the two wheel rods 15, a second support frame 39 and a third support frame 41 are erected. The two second support frames 39 are respectively installed on the top of the protective support frame 13. The two first support frames 38, the two motor support frames 40 and the two third support frames 41 are all installed on the base plate 36. The first support frame 38, the motor support frame 40, the second support frame 39 and the third support frame 41 respectively play a role in supporting and fixing the fixed rod 9, the DC motor 10 and the wheel rod 15, ensuring that these components remain stable during the movement process and guaranteeing the reliability and safety of the operation of the entire traction device.

[0023] In the present invention, the overall architecture collaboration foundation: The traction device uses two support brackets 13 as the main support framework to build the mechanical structure foundation of the entire device. Two lower limb carrying auxiliary support seats 1 are horizontally arranged between the support brackets and are firmly connected at the rear end by a rear support seat 12 to form a platform for the patient to place the lower limbs. The rear support seat 12 not only serves to connect the lower limb carrying auxiliary support seats but also provides a support area for the patient's back and buttocks. The right seat 30 and the left seat 31 provided inside it can meet the sitting posture requirements of the patient. Lower limb movement driving mechanism: The patient places the lower limbs steadily on the lower limb carrying auxiliary support seat 1, and the feet are placed on the front foot rest seat 22. When lower limb rehabilitation exercises are needed, the operator presses the control button 29 inside the support bracket 13. The control button 29, as a signal transmission hub, converts the operation instruction into an electrical signal and transmits it to the DC motor 10 electrically connected to it. After receiving the electrical signal, the stator and rotor inside the DC motor 10 start to rotate at high speed under the action of electromagnetic force. The rotation of the DC motor 10 is transmitted to the connecting splint two 8 through the fixed rod 9, driving the connecting splint two 8 to generate a linear displacement. Since the connecting splint two 8 is connected to the connecting splint one 5 by a connecting rope 6, under the guiding action of the runner 7, the connecting rope 6 transmits the pulling force of the connecting splint two 8 to the connecting splint one 5. The connecting splint one 5 is fixedly connected to the connecting movable fixed rod 4, thereby pulling the connecting movable fixed rod 4 to slide horizontally in the movable track groove 14 on the support bracket 13. The sliding of the connecting movable fixed rod 4 drives the connected lower limb carrying auxiliary support seat 1 to generate a horizontal displacement, simulating the flexion, extension, translation and other movements of the human lower limbs, so as to realize the rehabilitation training of the patient's lower limb muscles and joints. In this process, the rotating structure composed of the bottom fixed support column 3 and the movable support rod 2 at the bottom of the lower limb carrying auxiliary support seat 1 can flexibly rotate within a certain angle range according to the movement track of the lower limb carrying auxiliary support seat 1, playing a role in auxiliary support and balance adjustment to ensure the stability and safety of lower limb movement. Upper limb movement linkage process: The patient holds the board 17 with both hands, and the board 17 is embedded in the board movable groove 16 at the upper part of the support bracket 13. When the DC motor 10 drives the connecting rope 6 to move, while the connecting rope 6 pulls the connecting splint one 5, it will also generate an upward or backward pulling force on the board 17 through the runner 7. Since the board 17 is connected to the lower guard belt 19, and the other end of the lower guard belt 19 is fixed on the upper limb elbow support 18, this connection method causes the board 17 to slide in the board movable groove 16. During the process of the patient holding the board 17, the upper limb muscles need to actively exert force to maintain the grip strength and control the movement direction of the board 17, and at the same time cooperate with the movement rhythm of the lower limbs to realize the flexion, extension, stretching and other movements of the upper limbs. The wrist support belt 20 and the finger support belt 21 provide additional fixation and support for the patient's hands, helping the patient to exert force better and control the upper limb movement, so as to realize the coordinated rehabilitation training of the upper limbs and lower limbs.Through this ingenious mechanical structure design, only one DC motor is needed as the power source to drive the upper and lower limbs for rehabilitation exercises simultaneously, simplifying the operation process of the device and reducing the complexity and manufacturing cost of the device.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
