Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a walking aid training device for rapid rehabilitation nursing in cardiothoracic surgery. Background Technology

[0002] Cardiothoracic surgeries, such as lobectomy and esophagectomy, are highly invasive procedures. Post-operatively, patients often experience impaired cardiopulmonary function, weak lower limbs, and muscle tension in the lower back. Assistive walking devices are rehabilitation equipment designed to help the body support itself, maintain balance, and train for walking. They are widely used for individuals with lower limb dysfunction, post-operative rehabilitation, and the elderly and frail. Their core function is to reduce the load on the user's lower limbs through device support, helping users train for independent standing and walking, while providing basic support for rehabilitation training and aiding in the recovery of limb function.

[0003] Application number CN202220515387.4 discloses a walking aid for rapid rehabilitation nursing in cardiothoracic surgery, including a horizontal shaft. Both ends of the horizontal shaft are rotatably connected to the inner side of one end of a support member. The outer side of one end of the support member is rotatably connected to a first roller. A first motor is fixed to the upper side of the support member. A sliding groove is provided through the side of the support member. A second motor is fixed to the other end of the support member. The second motor is fixedly connected to one end of a pull rod. The other end of the pull rod is fixedly connected to a second fixing block. The second fixing block is fixedly connected to a third motor. The shaft of the third motor is fixedly connected to a roller. The roller passes through the sliding groove. The first motor drives the support member and the first roller to rotate. The third motor drives the first roller to rotate, thereby moving the walking aid.

[0004] The above-mentioned solution passively achieves the movement and steering of the walker through a motor. It can only achieve movement driven by the motor and cannot realize coordinated training of the upper and lower limbs. Patients do not participate in active training during use, which is not conducive to the rapid recovery of limb function. At the same time, the walker frame of this solution does not have any protective support components on the rear side. Combined with the physiological characteristics of patients after cardiothoracic surgery, such as weak cardiopulmonary function, weak limb strength, and poor body balance and coordination, patients are prone to leaning backward and shifting their center of gravity during standing and moving, which increases the risk of falls, bumps and other safety issues, making it difficult to guarantee the safety of the rehabilitation assistance process. Summary of the Invention

[0005] To address the aforementioned problems, this invention aims to provide a walking assistance training device for rapid rehabilitation nursing in cardiothoracic surgery. This device can guide patients to actively participate in rehabilitation training, provide stable lumbar and back support and limiting protection, and simultaneously realize rehabilitation training and energy recycling, providing patients with safe and efficient rehabilitation nursing.

[0006] The main idea of ​​the technical solution adopted in this invention is as follows: This invention guides the patient to actively exert force through an upper and lower limb linkage training mechanism, enabling the upper limbs to assist the lower limbs in stepping training. During the stepping training, the energy recovery and storage mechanism converts the patient's kinetic energy into compressed air pressure energy and stores it in a pressure tank, realizing energy recovery and reuse. It can provide power for subsequent massage without the need for an external power source. At the same time, a series of wave-like massage is achieved through a protective massage mechanism. The air supply is controlled by an electromagnetic valve, and the massage airbags are inflated and pressed in sequence. With the help of an overflow valve and a gas sensor, the system automatically realizes the cycle of inflation, deflation, reset, and re-inflation massage, which provides protection for the lower back while relieving muscle fatigue.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A walking aid training device for rapid rehabilitation nursing in cardiothoracic surgery includes a walking frame and a connecting plate disposed at the bottom of the walking frame, and further includes: The upper and lower limb linkage training mechanism is set inside the walking frame, including an upper limb training component and a lower limb training component connected thereto, for the upper limb to assist the lower limb in stepping training; An energy recovery and storage mechanism, located at the bottom of the lower limb training component, is used to convert and store walking kinetic energy as pressure energy; The protective massage mechanism, located on the upper side of the walking frame, is used to provide lumbar and back protection and to perform massage relaxation.

[0008] Furthermore, based on the above technical solutions, the upper limb training component includes: A guide plate is located on the front side of the walking frame, and guide grooves are symmetrically opened on it; Two traction ropes, one end of which runs through the upper side of the walking frame and is connected to a handle, and the other end is connected to the lower limb training component.

[0009] Furthermore, based on the above technical solutions, the lower limb training component includes: The first support rod is located at the bottom of the connecting plate, and two transmission sleeves are symmetrically rotated and fitted in its middle. Each of the two foot pedals is connected to a corresponding transmission sleeve; The connecting rod synchronously connects the transmission sleeve and the pull rope, and is used to transmit the traction force of the pull rope to the foot pedal.

[0010] Furthermore, based on the above technical solution, the connecting rod includes: The second support rod is connected to one side of the middle part of the first support rod, and a sliding rod is slidably connected to it; Two first connecting rods are fixedly sleeved at one end on the outside of the transmission sleeve and connected to the pulling rope; Two second links, one end of which is hinged to the first link, and the other end of which is hinged to the second support rod.

[0011] Furthermore, based on the above technical solutions, the energy recovery and storage mechanism further includes: Two extrusion tubes are respectively located at the bottom of the foot pedal, and a one-way air intake valve is installed at the bottom of the connecting plate; Two air supply pipes are connected to two extrusion pipes, one for each of them; The pressure tank is fixed to one side of the connecting plate and connected to two air supply pipes.

[0012] Furthermore, based on the above technical solutions, the protective massage mechanism includes: The protective panel is movably mounted on the rear side of the walking frame; Multiple massage airbags are embedded inside the protective plate and connected to the pressure tank; The overflow valve is located on the side of the massage airbag furthest from the pressure tank.

[0013] Furthermore, the above technical solution also includes an auxiliary mechanism, which includes: The sit-up assembly is movably disposed inside the walking frame and includes a support shaft and a sit-up plate rotatably connected to the support shaft; The suspension assembly, located on one side of the walking frame, includes an IV bottle hanging rod and a drainage clip.

[0014] The beneficial effects of this invention are: 1. This invention guides patients to actively exert force through an upper and lower limb linkage training mechanism, enabling the upper limbs to assist the lower limbs in stepping training. Through active training, the muscle strength of the upper and lower limbs is exercised simultaneously, accelerating the recovery of limb function.

[0015] 2. By setting a movable protective massage mechanism on the rear side of the walking frame, the present invention can not only provide stable support and limit protection for the patient's back and waist, reducing the risk of falls, but also relax the back muscles through massage airbags, relieve postoperative muscle tension and fatigue, and improve the patient's recovery comfort.

[0016] 3. This invention uses an energy recovery and storage mechanism to convert the kinetic energy generated by the patient's stepping training into pressure energy for storage, providing power to the protective massage mechanism and realizing the recycling of energy. It eliminates the need for additional external energy consumption, reducing usage and maintenance costs. Furthermore, through the linkage of a gas sensor and a solenoid valve, the massage process is automatically cyclical, reducing the operational burden on medical staff. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] The inventors discovered that existing walking aids passively move and turn using motors, enabling only passive movement and failing to provide coordinated upper and lower limb training. Patients do not actively participate in training during use, hindering rapid recovery of limb function. Furthermore, the walking aid frame lacks any protective support components at the rear. Considering the weakened cardiopulmonary function, limb strength, and poor balance and coordination of post-cardiothoracic surgery patients, they are prone to leaning backward and shifting their center of gravity during standing and movement, increasing the risk of falls and collisions, and compromising the safety of the rehabilitation process.

[0021] Based on the above findings, this application proposes a walking assistance training device for rapid rehabilitation nursing in cardiothoracic surgery. Through an upper and lower limb linkage training mechanism, the device guides the patient to actively exert force, enabling the upper limbs to assist the lower limbs in stepping training. During stepping training, an energy recovery and storage mechanism converts the patient's kinetic energy into compressed air pressure energy, storing it in a pressure tank for energy recovery and reuse. This provides power for subsequent massage without the need for an external power source. Simultaneously, a protective massage mechanism achieves a series of wave-like massages. Air supply is controlled by a solenoid valve, and the massage airbags are sequentially inflated and pressed. In conjunction with an overflow valve and a gas sensor, the device automatically achieves a cyclical massage of inflation, deflation, repositioning, and re-inflation, providing lumbar and back protection while relieving muscle fatigue.

[0022] Example See Figures 1-11 This application discloses a walking assistance training device for rapid rehabilitation nursing in cardiothoracic surgery, which is used to realize rehabilitation training, energy recovery, protective massage and postoperative auxiliary functions, and is adapted to the needs of patients in different rehabilitation stages after surgery. The walking assistance training device includes a walking frame 1, an upper and lower limb linkage training mechanism, an energy recovery and storage mechanism, a protective massage mechanism and an auxiliary mechanism.

[0023] The walking frame 1 is a frame structure with four symmetrically arranged anti-slip casters at the bottom, facilitating the movement of the walking training device by the patient. The casters also have braking mechanisms to secure the device during patient rest or training, preventing slippage. Alternatively, the anti-slip casters can be fitted with suction cups for stability during training. A connecting plate 11 is welded to the inner bottom of the walking frame 1 to support the lower limb training component 3 and the energy recovery and storage mechanism 4, meeting the force requirements of the patient during stepping training.

[0024] Next, the upper and lower limb linkage training mechanism is set inside the walking frame 1 to enable the upper limb to assist the lower limb in stepping training, which is suitable for patients with insufficient lower limb strength after surgery, and to exercise the upper and lower limbs simultaneously to accelerate the rehabilitation process. It includes an upper limb training component 2 and a lower limb training component 3 connected thereto.

[0025] The upper limb training component 2 is located on the front side of the walking frame 1 to facilitate the patient's upper limb exertion, and includes a guide plate 21 and two traction ropes 22.

[0026] Specifically, the guide plate 21 is fixed to the front middle of the walking frame 1 by welding. The side of the guide plate 21 closest to the human body is set perpendicular to the horizontal bar of the walking frame 1 to support and protect the front of the patient's body. The side of the guide plate 21 furthest from the human body is an inclined surface with two symmetrical guide grooves 211 to guide the traction rope 22, prevent the traction rope 22 from deviating during movement, and ensure stable transmission of traction force.

[0027] The traction rope 22 includes two ropes, both made of steel wire rope. The two traction ropes 22 are arranged symmetrically. One end of the traction rope 22 passes through the through hole on the upper side of the walking frame 1 and is fixedly connected to a handle 221. The surface of the handle 221 is provided with anti-slip texture for easy gripping by the patient. The other end of the traction rope 22 extends to the bottom of the walking frame 1 and is connected to the lower limb training component 3 to ensure that when the upper limb is pulled, the traction force can be transmitted to the lower limb training component 3 through the traction rope 22.

[0028] Furthermore, the lower limb training component 3 is located on the top of the connecting plate 11 and is linked with the upper limb training component 2 to realize stepping training. It includes a first support rod 31, two transmission sleeves 32, two foot pedals 33, and connecting rods.

[0029] Specifically, the first support rod 31 is fixed to the bottom two ends of the connecting plate 11 by welding and is set horizontally; two transmission sleeves 32 are symmetrically rotated in the middle of the first support rod 31. The transmission sleeves 32 are cylindrical sleeves with an inner diameter that matches the outer diameter of the first support rod 31. The inner wall is provided with bearings to ensure that the transmission sleeves 32 can only rotate around the first support rod 31 and cannot produce axial displacement.

[0030] The two foot pedals 33 correspond to the left and right feet respectively. The two foot pedals 33 are fixedly connected to the two transmission sleeves 32 one-to-one through the connecting rod 331. The foot pedals 33 are rectangular pedals with anti-slip texture on the surface to prevent the patient's feet from slipping when stepping.

[0031] The connecting rod is located between the two foot pedals 33 and is used to synchronously connect the transmission sleeve 32 and the pull rope 22 to transmit the traction force of the pull rope 22 to the foot pedals 33. It includes a second support rod 34, a sliding rod 35, two first connecting rods 36 and two second connecting rods 37.

[0032] Specifically, the second support rod 34 is fixedly connected to one side of the middle of the first support rod 31 by welding and is perpendicular to the first support rod 31. At the same time, the second support rod 34 is also located in the middle position of the two transmission sleeves 32. A sliding rod 35 is slidably connected to the second support rod 34. The sliding rod 35 can slide along the axial direction of the second support rod 34. Two connecting ears are symmetrically provided on the outer side of the sliding rod 35 for hinged connection with the second connecting rod 37.

[0033] One end of each of the two first connecting rods 36 is fixedly sleeved on the outside of the transmission sleeve 32 by welding, and can rotate synchronously with the transmission sleeve 32; a pull rope 22 is fixedly connected to one side of the first connecting rod 36.

[0034] The two second links 37 correspond one-to-one with the two first links 36. One end of the second link 37 is hinged to the first link 36 by a pin, and the other end is hinged to the connecting lug on the outside of the sliding rod 35 by a pin.

[0035] It should be noted that the two first links 36 are arranged symmetrically on the left and right, and their setting direction and movement direction are always synchronized and opposite to each other, so as to realize the natural gait of the patient's left and right lower limbs alternating steps.

[0036] When the patient pulls the left handle upwards with their left hand, the left traction rope 22 moves upwards, pulling the left first link 36 upwards and backwards, causing the left transmission sleeve 32 to rotate, thus lifting the right foot pedal 33 upwards. At this time, the right limb relaxes naturally, and under the force of foot pressure and the rebound of the compression tube, the right first link 36 swings downwards and forwards, causing the right foot pedal 33 to fall back down. When the patient pulls the right handle upwards with their right hand, the right traction rope 22 moves upwards, pulling the right first link 36 upwards and backwards, lifting the right foot pedal 33. The left first link 36 swings downwards and forwards, causing the left foot pedal 33 to fall back down. The left and right first links 36 always swing synchronously in opposite directions, alternating between the two movements to achieve the up-and-down reciprocating motion of the two foot pedals 33, completing the stepping training.

[0037] Next, the energy recovery and storage mechanism 4 is located at the bottom of the lower limb training component 3. It is used to convert the kinetic energy generated during the patient's stepping training into pressure energy and store it, and then provide power to the protective massage mechanism 5 to realize the recycling of energy. It includes two compression tubes 41, two air supply tubes 42 and a pressure tank 43.

[0038] Specifically, the two compression tubes 41 are respectively located at the bottom of the two foot pedals 33. The compression tubes 41 are made of elastic rubber tubes, which can contract under the pressure of the foot pedals 33 and automatically return to their original position after releasing the pressure. The bottom of the compression tube 41 passes through the connecting plate 11 and is fixedly equipped with a one-way air intake valve 411. The one-way air intake valve 411 enables air to enter the compression tube 41 in one direction. That is, when the compression tube 41 contracts, the one-way air intake valve 411 closes to prevent internal air backflow; when the compression tube 41 returns to its original position and expands, the one-way air intake valve 411 opens to draw in outside air, ensuring that the compression tube 41 can repeatedly contract and expand to continuously generate pressure.

[0039] The two air supply pipes 42 are respectively connected to the two extrusion pipes 41 in a one-to-one correspondence. One end of the air supply pipe 42 is connected to the extrusion pipe 41 through a sealing joint, and the other end is connected to the pressure tank 43. The air supply pipe 42 is equipped with a one-way air outlet valve to prevent the compressed air in the pressure tank 43 from flowing back to the extrusion pipe 41.

[0040] The pressure tank 43 is fixed to one side of the connecting plate 11 by a bracket. A solenoid valve 431 is provided at the outlet of the pressure tank 43 to control the output and shut-off of compressed air in the pressure tank 43. Medical staff can control the inflation and de-inflation of the massage airbag 52 through the solenoid valve 431 according to the patient's massage needs. The operation is convenient. An exhaust pipe 432 is also connected to the outlet end of the pressure tank 43. One end of the exhaust pipe 432 is connected to the pressure tank 43, and the other end is connected to the protective massage mechanism 5.

[0041] Next, the protective massage mechanism 5 is set on the upper side of the walking frame 1 to provide back protection for the patient, avoid bending of the back and uneven force when the patient walks or trains, and at the same time use the pressure energy stored in the energy recovery and storage mechanism 4 to perform back massage and relaxation, relieve postoperative back fatigue and muscle tension, and promote blood circulation. It includes a protective plate 51, multiple massage airbags 52 and an overflow valve 53.

[0042] The protective plate 51 is movably mounted on the upper rear side of the frame 1. Specifically, one end of the protective plate 51 is hinged to the upper rear side of the walking frame 1, and the other end is limited and locked by a locking rod 511 set on the walking frame 1. The protective plate 51 can be rotated upward around the hinge point to open, so that the patient can enter smoothly from the rear side of the walking frame 1. After the patient is in position, the protective plate 51 is rotated back to its original position and locked and limited by the locking rod 511, so that the protective plate 51 fits the patient's waist and back and plays a protective role.

[0043] The protective plate 51 has an arc-shaped groove on one side that fits against the patient's lower back. Multiple massage airbags 52 are evenly embedded in the groove. In this preferred embodiment, there are 10 massage airbags 52, arranged in two rows of 5 each. The massage airbags 52 are made of silicone material to gently massage the muscles of the lower back. All massage airbags 52 are interconnected sequentially through air ducts 521, and the massage airbag 52 closest to the pressure tank 43 is connected to the pressure tank 43 through an exhaust pipe 432.

[0044] When the solenoid valve 431 is opened, the gas in the pressure tank 43 begins to inflate the massage airbags 52 sequentially, achieving a wave-like massage. The specific process is as follows: compressed air first enters the first massage airbag 52. After the first airbag is full, its internal pressure increases, which can gently press the corresponding local area of ​​the patient's lower back. Then, the gas flows into the second massage airbag 52 through the series air guide tube, and so on, until all the massage airbags 52 are fully inflated, driving all the airbags to form a complete wave-like massage.

[0045] An overflow valve 53 is located on the side of the massage airbag 52 furthest from the pressure tank 43. When the massage airbag 52 is full of gas, the overflow valve 53 automatically opens, releasing the gas inside the massage airbag 52. A gas sensor 522 is installed on the protective plate 51 at the outlet of the overflow valve 53. Its detection probe is directly opposite the outlet of the overflow valve 53, with a distance of 3-5 cm between the sensor and the outlet, ensuring accurate detection of the gas flow rate and pressure released by the overflow valve 53.

[0046] Gas sensor 522 is electrically connected to solenoid valve 431 at the outlet of pressure tank 43 to realize automatic cycle control of massage, air release, and reset. The specific linkage logic is as follows: When the last massage airbag 52 is filled with gas and triggers the overflow valve 53 to open for air release, gas sensor 522 detects a sudden and rapid drop in pressure, determines that overflow valve 53 is releasing gas, and immediately sends a control signal to solenoid valve 431 to close solenoid valve 431, stopping pressure tank 43 from inflating massage airbag 52; as overflow valve 53 continues to release gas, the pressure in all massage airbags 52 gradually decreases. When gas sensor 522 detects that the pressure has dropped to near atmospheric pressure and remains stable, it determines that air release is over and overflow valve 53 has automatically closed. At this time, gas sensor 522 sends a control signal again to reopen solenoid valve 431, and pressure tank 43 resumes to inflate massage airbag 52 sequentially. This cycle is repeated to realize automatic cycle of wave massage, air release, airbag reset, and wave massage again, without the need for manual operation by medical staff, which ensures the massage effect and avoids safety hazards caused by abnormal pressure.

[0047] Next, the assistive mechanism is used to provide additional rehabilitation assistance to patients to meet the special needs of patients after cardiothoracic surgery, such as difficulty in sitting up, need for infusion or drainage, and includes a sitting-up component 6 and a suspension component.

[0048] The sitting-up assembly 6 is movably disposed inside the walking frame 1 to provide support and rest for patients when they are tired from training, and includes a support shaft 61 and a sitting-up board 62.

[0049] The support shaft 61 includes two shafts, which are fixedly mounted on the two sides of the walking frame 1. One side of the sitting plate 62 is a hollow cylinder, which is sleeved on the outside of the support shaft 61 and can be rotatably connected to the support shaft 61; the other side is a hollow semi-cylindrical cylinder, which can overlap the support shaft 61. The walking frame 1 is provided with a limit protrusion 63 on one side of the hollow cylinder.

[0050] When the patient needs to rest, the sitting board 62 is rotated so that one side of the hollow cylinder of the sitting board 62 rotates around the support shaft 61 to a horizontal position. At this time, the hollow semi-cylinder on the other side of the sitting board 62 overlaps the support shaft 61, providing a reliable support and resting surface for the patient. When not in use, the sitting board 62 is rotated in the opposite direction so that it fits against the inside of the walking frame 1. At this time, the limiting protrusion 63 vertically limits the board body of the sitting board 62, without occupying space.

[0051] Furthermore, the suspension assembly includes an infusion bottle hanging rod 7 and a drainage clip 8. Specifically, the bottom of the infusion bottle hanging rod 7 is fixed to one side of the frame 1. The infusion bottle hanging rod 7 can be configured as a height-adjustable rod in the prior art to adapt to different infusion needs. The top of the infusion bottle hanging rod 7 is provided with a hook for suspending the infusion bottle to adapt to the patient's infusion needs. The drainage clip 8 is fixed to the side away from the infusion bottle hanging rod 7. The drainage clip 8 can be a hook adapted to a drainage bag or a retaining ring adapted to a drainage bottle to adapt to different drainage needs of the patient. The drainage clip 8 is height-adjustable. Specifically, the frame 1 has a sliding groove 81, and one side of the sliding groove 81 is provided with multiple retaining slots 82. The drainage clip 8 is provided with a retaining rod 83, which slides inside the sliding groove 81. When it slides to the required height, it locks into the retaining slot 82 to fix its position.

[0052] Application Examples In this application example, the patient is a 58-year-old female, three days post-lobectomy. Her vital signs are stable, with no obvious complications, and she is in the early stages of recovery. She has weak lower limb strength and cannot walk independently for extended periods. She also experiences back muscle tension and requires gentle limb rehabilitation training. Regular intravenous infusions are necessary, with occasional drainage required. The application steps are as follows: 1. Patient positioning: Rotate the protective plate 51 upwards to assist the patient to enter from the back of the walker 1, place both feet on the corresponding foot pedals 33, hold the handles 221 with both hands, keep the back and waist against the protective plate 51, rotate the protective plate 51 back to its original position and limit it through the locking rod 511; hang the infusion bottle on the hook of the infusion bottle hanging rod 7, and when drainage is needed, fix the drainage bag on the drainage clip 8.

[0053] 2. Upper and lower limb coordination training: The patient slowly pulls the handles 221 on both sides, and moves the foot pedals 33 alternately in the manner of "pulling left and lifting right, pulling right and lifting left" to carry out upper and lower limb rehabilitation training.

[0054] 3. Rest assistance: When tired from training, rotate the sitting board 62 to a horizontal position so that the hollow semi-cylinder of the sitting board 62 overlaps the support shaft 61, and the patient sits down to rest.

[0055] 4. Massage and relaxation: During or after training, open the solenoid valve 431 at the outlet of the pressure tank 43. The pressure tank 43 inflates the massage airbag 52 sequentially to achieve wave-like massage. When the gas sensor 522 detects that the overflow valve 53 is venting, it controls the solenoid valve 431 to close. After the venting is completed, it automatically opens to complete the cycle massage and relieve the tension of the back muscles.
