Description

Technical Field

[0001] The invention belongs to the technical field of orthopedic rehabilitation training, and in particular is a multifunctional orthopedic postoperative rehabilitation nursing device. Background Art

[0002] Rehabilitation after orthopedic surgery is a complex and lengthy process that requires the joint efforts of patients and medical staff. In this process, pain is an important factor that cannot be ignored, which directly affects the patient's rehabilitation efficiency and psychological state. Although the existing orthopedic postoperative rehabilitation nursing devices assist patients' rehabilitation training to a certain extent, there are still many deficiencies in dealing with the relationship between pain and rehabilitation efficiency.

[0003] Rehabilitation therapy training is generally divided into active training and passive training; active training means that the patient relies on his own muscle strength to exercise, and achieves the treatment purpose by directly contracting and relaxing the muscles. Passive training means that the patient relies entirely on external forces (such as therapists, machines, etc.) to exercise. In the early stages of rehabilitation treatment, patients may be unable to perform active exercises due to insufficient muscle strength or pain. At this time, passive training can help patients increase muscle tension and prevent muscle atrophy. When performing passive training, most of the existing orthopedic postoperative rehabilitation nursing devices assist patients in rehabilitation training according to the preset training difficulty and speed. These devices usually control training parameters such as range of motion, speed and resistance through fixed mechanical structures or programs. However, in actual applications, the patient's rehabilitation process is gradual and there are individual differences. Since the training parameters of the existing device are preset, when the patient's muscles are tense due to pain, the device will still train according to the original plan. This mismatched training mode not only fails to effectively relieve the patient's pain, but may also aggravate the pain due to excessive training. Continuous pain may cause patients to resist rehabilitation training and be unwilling to continue training. This resistance will directly affect the patient's enthusiasm for rehabilitation, thereby reducing the efficiency of rehabilitation.

[0004] In view of the shortcomings of existing technologies in dealing with the relationship between pain and rehabilitation efficiency, there is an urgent need for a multifunctional orthopedic postoperative rehabilitation nursing device that can better adapt to the patient's rehabilitation needs and reduce the occurrence of pain. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a multifunctional orthopedic postoperative rehabilitation nursing device, which can adjust the training parameters in real time according to the individual differences and rehabilitation progress of the patients, thereby reducing the occurrence of pain and improving the rehabilitation training effect.

[0006] In order to achieve the above-mentioned objectives, the technical solution of the present invention is as follows: a multifunctional orthopedic postoperative rehabilitation care device, comprising a seat body and a function box; the seat body is provided with a training component for rehabilitation training and a hot compress component for providing local hot compress to the patient; the function box is provided with a driving component for providing power to the training component and an adjustment component for lowering the operating parameters of the training component; the training component is provided with a sensing component for converting the patient's stress response caused by pain into starting the operation of the adjustment component.

[0007] The above scheme has the following beneficial effects:

[0008] This solution provides rehabilitation training for patients through training components. When patients develop stress reactions due to pain during training, the sensing component converts this stress reaction into a signal to start the operation of the adjustment component, thereby starting the adjustment component to lower the operating parameters of the training component and automatically switching the training difficulty to a level suitable for the patient. At the same time, the hot compress component provides local heating to the patient's surgical site to promote blood circulation, relieve muscle tension and reduce pain.

[0009] Compared with existing technologies, this solution can monitor the patient's stress response in real time and automatically adjust training parameters to ensure that each patient can obtain the rehabilitation training intensity that suits him or her best, avoiding the problem of overtraining that may occur in traditional rehabilitation training and reducing the occurrence of pain.

[0010] Furthermore, the training component includes a first support plate and a second support plate; the first support plate and the second support plate are rotatably connected, and the second support plate is rotatably connected to the seat body; the bottom of the first support plate and the bottom of the second support plate are both provided with a telescopic component for driving the support plate to deflect.

[0011] Beneficial effects: The telescopic components drive the support plate to deflect, which can simulate the natural flexion and extension of the lower limbs of the human body. This exercise mode helps to restore the strength and flexibility of the lower limb muscles and promote the recovery of joint mobility.

[0012] Furthermore, the telescopic assembly includes an outer shaft and an inner shaft; a sealed cavity is provided in the outer shaft; the inner shaft is embedded in the outer shaft, and the inner shaft and the sealed cavity are slidably matched; in one group of telescopic assemblies, the inner shaft is rotatably connected to the first support plate at one end away from the outer shaft, and the outer shaft is rotatably connected to the second support plate at one end away from the inner shaft; in another group of telescopic assemblies, the inner shaft is rotatably connected to the second support plate at one end away from the outer shaft, and the outer shaft is rotatably connected to the bottom of the seat body at one end away from the inner shaft.

[0013] Beneficial effects: The telescopic component adopts an outer shaft and an inner shaft design, and the inner shaft is embedded in the outer shaft and slides in the sealed cavity. This structure ensures that the telescopic component can maintain a stable motion trajectory during the telescopic process, avoiding inaccurate training or patient discomfort caused by shaking or offset. At the same time, the rotational connection between the inner shaft and the outer shaft allows the support plate to deflect smoothly, simulating the natural flexion and extension of the lower limbs.

[0014] Furthermore, the hot compress assembly includes an electric heating tube, a hot compress tube and a circulation tube; a heating tank for storing a fluid medium is arranged in the functional box; the electric heating tube is arranged on the side wall of the heating tank; the heating tank is connected with the hot compress tube and the circulation tube respectively; hot compress cavities are arranged in the first support plate and the second support plate, and the hot compress cavities are connected with the hot compress tube and the circulation tube respectively; a hot water pump is arranged at the connection point between the hot compress tube and the heating tank.

[0015] Beneficial effects: The hot compress component uses a circulation pipe to connect the heating tank, the hot compress pipe and the circulation pipe to form a closed heat circulation system. The hot water pump draws the heated fluid medium into the hot compress pipe, passes through the hot compress cavity to provide hot compress to the patient, and then flows back to the heating tank through the circulation pipe for reheating. This recycling method not only improves the utilization efficiency of thermal energy, but also reduces energy consumption, which is in line with the concept of energy conservation and environmental protection.

[0016] Furthermore, a functional cavity is arranged in the functional box; the driving assembly comprises a servo motor and a rotating shaft; the servo motor is located in the functional cavity; the output shaft of the servo motor is coaxially and fixedly connected with the rotating shaft; an inclined eccentric cam is eccentrically connected to the rotating shaft; a transmission groove is arranged at the top of the functional cavity; a transmission piston is arranged in the transmission groove, and the transmission piston and the transmission groove are slidably matched; a transmission rod is arranged at the bottom of the transmission piston, and the transmission rod fits with the inclined eccentric cam by its own gravity; a conduit is connected to the top of the transmission groove, and the conduit is respectively connected to the sealing cavity.

[0017] Beneficial effects: The servo motor drives the rotating shaft to rotate, the rotating shaft drives the inclined eccentric cam to rotate, the inclined eccentric wheel rotates to drive the transmission rod to move up and down periodically, the movement of the transmission rod drives the transmission piston to move, and the air in the transmission groove-conduit-sealed cavity is continuously expanded and contracted during the movement of the transmission piston, thereby accurately controlling the extension and contraction of the telescopic assembly and the deflection angles of the first support plate and the second support plate, thereby meeting the precise requirements of lower limb flexion and extension training.

[0018] Furthermore, a negative pressure channel is also provided in the function box; a throat is also provided in the hot compress tube; the negative pressure channel connects the function cavity and the throat; the adjustment component includes a cylinder; the cylinder and the negative pressure channel are slidably matched; a first limiting groove is provided in the cylinder; a plurality of first limiting protrusions are also circumferentially provided on the rotating shaft, and the first limiting protrusions are slidably matched with the first limiting groove; the cylinder passes through the inclined eccentric cam, and the cylinder is fixedly connected to the inclined eccentric cam; a constant pressure channel is also connected to one side of the negative pressure channel, and the constant pressure channel is used to communicate with the outside world; the top of the constant pressure channel The induction pipe is connected to the inner part; an elastic cushion layer and a stopper are arranged in the induction pipe; a latch is arranged at the bottom of the elastic cushion layer; the stopper is slidably matched with the induction pipe; a through slot is arranged in the stopper; the latch passes through the top of the through slot and extends into the through slot, and the latch is slidably matched with the stopper; a pair of limiting balls are arranged in the through slot; the limiting balls are slidably matched with the through slot; gradient grooves are also arranged on both sides of the induction pipe, and the gradient grooves are used to accommodate the limiting balls when the latch contacts the limiting balls; the stopper is used to block the constant pressure channel when the limiting balls lose the restraint of the latch.

[0019] Beneficial effect: By utilizing the elastic cushion layer to generate elastic deformation, the pin is pulled upward, so that the block loses the restraint of the limiting ball and slides downward into the constant pressure channel to block the constant pressure channel; when the fluid medium passes through the throat, negative pressure will be generated in the negative pressure channel. Since the constant pressure channel is blocked, air cannot be obtained from the outside to maintain the air pressure balance of the negative pressure channel, so that the negative pressure generated by the negative pressure channel cannot be offset. The negative pressure at this time can drive the cylinder to slide in the negative pressure channel, thereby driving the inclined eccentric cam to move, shortening the movement distance between the transmission rod and the inclined eccentric cam, thereby reducing the telescopic amount of the telescopic assembly.

[0020] Through the clever design of the negative pressure channel and the constant pressure channel, when the fluid medium generates negative pressure through the throat, if the constant pressure channel is blocked, the negative pressure will not be able to obtain air from the outside to balance, thus maintaining the negative pressure state. This negative pressure state can drive the cylinder to slide in the negative pressure channel, and then drive the inclined eccentric cam to move, realizing the automatic adjustment of the telescopic amount of the telescopic component. This automatic adjustment mechanism can dynamically adjust the range of motion of the training component according to actual needs, improving the adaptability and flexibility of the equipment.

[0021] Furthermore, the sensing component includes a plurality of restraining belts; the restraining belts are respectively arranged on the surfaces of the first support plate and the second support plate; pneumatic grooves are arranged in the first support plate and the second support plate, and the pneumatic grooves are connected to the sensing pipe; one end of the restraining belt is fixedly connected to the first support plate and the second support plate respectively, and the other end of the restraining belt is arranged with a buckle carrier; a buckle slot is arranged in the bottom of the buckle carrier; a second limiting slot is arranged on one side of the buckle slot, and a spring and a second limiting protrusion are arranged in the second limiting slot; both ends of the spring are respectively fixedly connected to the inner wall of the second limiting slot and the second limiting protrusion; the second limiting protrusion is slidably matched with the second limiting slot; a piston carrier is slidably matched in the buckle slot; a sliding slot is arranged on the top of the piston carrier; a ring is slidably matched in the sliding slot, and the ring is slidably matched with the clamping slot; the bottom of the piston carrier is slidably matched with the pneumatic groove.

[0022] Beneficial effects: when the patient's lower limbs are placed on the first support plate and the second support plate, the patient's lower limbs are fixed by the restraint belt, and the buckle carrier at one end of the restraint belt is inserted into the pneumatic groove, and fixed by engaging with the sliding groove through the second limiting protrusion; when the patient has a stress response such as trembling or muscle contraction / tightness due to pain, the patient's fixed part will drive the restraint belt to be lifted upward, thereby driving the buckle carrier to move upward, and the buckle carrier will drive the piston carrier to move upward during the upward movement, thereby generating negative pressure in the pneumatic groove-sensing pipeline, and then causing the elastic cushion layer to produce elastic deformation, thereby lifting the pin until the constant pressure channel is blocked, thereby starting the operation of the adjustment component.

[0023] In this solution, when the patient moves his limbs due to stress reactions such as pain, tremors, or muscle contraction / tightness, the sensing component can respond quickly. Through the linkage of the restraint belt, the buckle carrier and the piston carrier, this movement is converted into a change in negative pressure in the pneumatic groove-sensing pipeline. This design enables the system to capture the patient's tiny movements in real time and provide timely feedback for subsequent adjustments. The generation of negative pressure causes the elastic cushion layer to deform elastically, thereby lifting the pin and blocking the constant pressure channel. This chain reaction triggers the operation of the adjustment component, which means that the device can automatically adjust the treatment parameters according to the patient's real-time status.

[0024] At the same time, the sensing components and the regulating components in this solution are both mechanical structure designs. Compared with electronic equipment, the mechanical structure design is relatively simple and easy to maintain.

[0025] The parts of mechanical structures can usually be easily replaced and repaired, reducing maintenance costs. Mechanical structures are not affected by electronic interference and other problems during operation, so they have higher safety. In particular, electronic medical devices are widely used in hospital environments, and these devices may generate electronic interference signals when working. Therefore, the pure mechanical structure used in this solution is more suitable for this scenario, with advantages such as high sensitivity and high stability.

[0026] Furthermore, one side of the negative pressure channel is also connected to a backup air pump; the block is made of magnetic material, and an electromagnet for resetting the block is also provided in the constant pressure channel.

[0027] Beneficial effect: When the range of motion of the training component needs to be restored, the backup air pump is started to fill the negative pressure channel with gas, so that positive pressure is generated in the negative pressure channel, so that the cylinder moves outward along the negative pressure channel, thereby driving the inclined eccentric cam to move until the range of motion when the transmission rod contacts the inclined eccentric cam is increased. Then, the electromagnet is started to use magnetic force to push the block upward, so that the block is reset.

[0028] By filling the negative pressure channel with gas through a backup air pump, the pressure state in the negative pressure channel can be easily changed from negative pressure to positive pressure. This pressure change can drive the movement of the cylinder and the inclined eccentric cam, thereby adjusting the range of motion when the transmission rod contacts the inclined eccentric cam. This design provides a high degree of flexibility and adjustability, so that the range of motion of the training component can be precisely adjusted as needed.

[0029] Furthermore, it also includes an image acquisition module and a control module; the image acquisition module is used to obtain the patient's facial expressions; the control module is used to verify the actual situation of the patient's pain based on the facial expressions, and control the operation of the backup air pump, electromagnet, servo motor, electric heating tube and hot water pump.

[0030] Beneficial effects: The control module can verify the patient's actual pain situation based on the facial expression information obtained by the image acquisition module, and control the operation of the backup air pump, electromagnet and servo motor accordingly. This precise control helps to adjust the treatment parameters according to the patient's real-time pain status, such as the temperature and pressure of the hot compress and the deflection angle of the support plate, thereby providing a more personalized and accurate treatment plan.

[0031] Furthermore, armrests are provided on both sides of the seat body; humidity sensors and heart rate sensors are provided on the armrests respectively; the humidity sensor is used to obtain the patient's sweating conditions; the heart rate sensor is used to obtain the patient's heart rate changes; the control module is also used to assist in judging the patient's pain level based on the information from the humidity sensor and the heart rate sensor, and to control the operation of the standby air pump, electromagnet, servo motor, electric heating tube and hot water pump.

[0032] Beneficial effects: Humidity sensors can monitor patients' sweating in real time, which is one of the important indicators for assessing the patient's pain level. Increased sweating may mean that the patient is experiencing pain or discomfort.

[0033] The heart rate sensor can obtain the patient's heart rate changes in real time, and the changes in heart rate can also reflect the patient's pain level and emotional state.

[0034] Based on the multi-dimensional pain assessment results, the patient's pain level can be assessed more accurately. This comprehensive assessment method is more reliable than a single indicator. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The specific implementation process is as follows: For example, when a patient with a tibia and fibula shaft fracture uses the device, the patient's lower limbs are fixed by a restraint belt 4. Then the electric heating tube 513 and the hot water pump 511 are started, and the servo motor 502 is started at the same time.

[0061] When the hot compress assembly is working, the electric heating pipe 513 heats the water in the heating tank 512 to a preset temperature, and then the hot water is pumped into the hot compress pipe 507 through the hot water pump 511, poured into the hot compress cavity 7 through the hot compress pipe 507, and then flows back to the heating tank 512 from the circulation pipe 514. When the hot water passes through the throat 508, negative pressure will be generated in the negative pressure channel 509, and the constant pressure channel 515 will absorb air from the outside to maintain the air pressure balance in the negative pressure channel 509, and the cylinder 504 will not move at this time.

[0062] When the training component is running, the servo motor 502 drives the rotating shaft 503 to rotate, the rotation of the rotating shaft 503 drives the cylinder 504 to rotate, the rotation of the cylinder 504 drives the inclined eccentric cam 505 to rotate, and the inclined eccentric cam 505 drives the transmission rod 607 to move back and forth up and down during the rotation, and the transmission rod 607 drives the transmission piston 606 to move back and forth up and down, so that the air continues to expand and contract, driving the inner shaft 604 to reciprocate and telescope in the sealed cavity 603 of the outer shaft 602, thereby driving the first support plate 2 and the second support plate 9 to deflect relative to each other, and the second support plate 9 and the seat body 1 to deflect relative to each other, so as to perform flexion and extension training.

[0063] When the patient feels pain and produces a stress reaction, such as muscle contraction or shaking, the restraint belt 4 will pull the buckle carrier 401 to move upward under the drive of muscle contraction or shaking, and the buckle carrier 401 moves upward to drive the piston carrier 202 to move upward. The upward displacement of the piston carrier 202 reduces the air pressure in the sensing pipe 517, so that the elastic cushion layer 518 produces elastic deformation, and the deformation of the elastic cushion layer 518 drives the latch 519 to move upward, so that the block 520 loses its restraint and falls into the constant pressure channel 515, so that the constant pressure channel 515 cannot obtain air from the outside. The air is used to balance the negative pressure channel 509, thereby maintaining a negative pressure state. At this time, the cylinder 504 will move to the right under the action of the negative pressure, thereby moving the inclined eccentric cam 505 to the right, making the transmission rod 607 contact with the end of the inclined eccentric cam 505 with a shorter outer diameter, thereby reducing the range of motion of the transmission rod 607, thereby reducing the expansion and contraction strength of the transmission rod 607 and the transmission piston 606 to the air, until the expansion and contraction amount of the inner shaft 604 in the outer shaft 602 is reduced, and finally the deflection angle of the first support plate 2 and the second support plate 9 is reduced, thereby reducing the range of motion of the patient's legs.

[0064] The difference between the second embodiment and the first embodiment is that one side of the negative pressure channel 509 is also connected to a backup air pump 510; the stopper 520 is made of magnetic material, such as the attached Figure 4 As shown, an electromagnet 516 for resetting the stopper 520 is also provided in the constant pressure channel 515 .

[0065] Specific implementation process: When it is necessary to restore the patient's range of motion during training, the backup air pump 510 is started to increase the air pressure in the negative pressure channel 509, thereby pushing the cylinder 504 to move to the left, thereby restoring the range of motion of the training component during flexion and extension training.

[0066] Then, the electromagnet 516 is started, so that the stopper 520 moves upward under the action of magnetic force, so that the latch 519 is reinserted between the limiting balls 522 to achieve resetting.

[0067] The only difference between the third embodiment and the second embodiment is that it also includes an image acquisition module and a control module; the image acquisition module is used to obtain the facial expressions of the patient; the control module is used to verify the actual pain of the patient based on the facial expressions, and to control the operation of the backup air pump 510, the electromagnet 516, the servo motor 502, the electric heating pipe 513 and the hot water pump 511. In this embodiment, the image acquisition module is a camera, which is mounted at any position where the facial expressions of the patient can be captured, such as on the wall directly opposite the patient.

[0068] Specific implementation process: When the patient is in the training process, the image acquisition module is started to capture the patient's facial expressions in real time, providing visual basis for the subsequent pain assessment of the control module. For example, if the patient's expression is hideous or the facial muscles are twitching, the control module determines that the patient's pain is real, and controls the electric heating tube 513 to operate, so that the temperature of the hot water in the heating tank 512 increases (within a certain range, such as between 40°C and 50°C), relieves the patient's pain, and reduces the speed of the servo motor 502. If the patient's expression is calm or does not change, it indicates that the patient does not feel pain during the training process or the pain is within the normal range (indicating that the induction component is misjudged, that is, the stress reaction of the patient's legs is not caused by the pain caused by the training), then the control module controls the standby air pump 510 to operate, reset the inclined eccentric cam 505, and then starts the electromagnet 516 to reset the block 520.

[0069] The only difference between Example 4 and the above-mentioned Example 3 is that armrests 3 are provided on both sides of the seat body 1; humidity sensors 8 and heart rate sensors 10 are respectively provided on the armrests 3; the humidity sensor 8 is used to obtain the patient's sweating conditions; the heart rate sensor 10 is used to obtain the patient's heart rate changes; the control module is also used to assist in judging the patient's pain level based on the information of the humidity sensor 8 and the heart rate sensor 10, and control the operation of the standby air pump 510, the electromagnet 516, the servo motor 502, the electric heating tube 513 and the hot water pump 511.

[0070] Specific implementation process: When the control module obtains the image captured by the image acquisition module, it also obtains the information of the heart rate sensor 10 and the humidity sensor 8 at the same time, combines the three information, and comprehensively judges the patient's pain condition and pain degree.

[0071] For example, the patient sits on the chair body 1 with both hands naturally placed on the armrests 3 .

[0072] The humidity sensor 8 starts to monitor the patient's sweating, and the heart rate sensor 10 synchronously monitors the patient's heart rate changes.

[0073] The image acquisition module is activated to capture the patient's facial expressions in real time, providing a visual basis for subsequent pain assessment.

[0074] The control module receives data from the humidity sensor 8 and the heart rate sensor 10 and performs a preliminary assessment of the pain level.

[0075] At the same time, the image acquisition module sends the patient's facial expression data to the control module, and the control module uses image recognition technology to further verify the patient's actual pain situation.

[0076] Based on the comprehensive evaluation results, the control module adjusts the operating parameters of the backup air pump 510, the electromagnet 516, the servo motor 502, the electric heating pipe 513 and the hot water pump 511 to provide a more personalized and accurate treatment plan.

[0077] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
