Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a rehabilitation device for children in the cardiology department. Background Art

[0002] Cardiology diseases are more common in children, such as congenital heart disease and cardiomyopathy. Such diseases usually require children to stay in bed for a long time to reduce the burden on the heart and prevent the condition from getting worse. However, long-term bed rest can easily cause lower limb muscle atrophy, which in turn affects the rehabilitation effect. Therefore, during the treatment period, in addition to drug treatment, appropriate rehabilitation training is also needed to improve the physical condition of the child. But the reality is that some children with poor physical condition cannot sit up and perform regular rehabilitation exercises.

[0003] In response to this problem, the technical solution with patent number CN220443133U proposes a rehabilitation device for children with cardiology. The device has motion components symmetrically installed on both sides of the rehabilitation bed, and the lower limbs of the children are exercised through the motion components. However, this technical solution has certain defects: when the children are exercising their lower limbs, since there is no device to fix the children on the rehabilitation bed, the children's bodies move frequently during the exercise, which greatly reduces the exercise effect; at the same time, during the exercise of the children, their backs will sweat, which will cause a stuffy feeling. Summary of the invention

[0004] The present invention is intended to provide a rehabilitation device for children in the cardiology department, so as to solve the problems of easy movement of the child's body and stuffiness of the back during use of the existing rehabilitation device.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a rehabilitation device for children in the cardiology department, including a rehabilitation bed, on which a lower limb exercise unit for exercising the lower limbs of the child and a waist and back positioning unit are provided; the waist and back positioning unit includes a positioning pad, and a No. 1 positioning part and a No. 2 positioning part are respectively provided at positions near the two sides of the rehabilitation bed in the positioning pad, and the No. 1 positioning part and the No. 2 positioning part both include a number of pressure-adjustable positioning air bags; a number of pressure-adjustable massage air bags are provided in the middle position of the positioning pad; a number of No. 1 ventilation holes are opened on the rehabilitation bed below the positioning pad, a number of No. 2 ventilation holes are provided on the positioning pad, and the interior of the positioning pad is filled with fillers.

[0006] The beneficial effects of this program are as follows: when exercising the lower limbs of the child, first let the child lie on the positioning pad with his waist and back. By accurately adjusting the pressure value of the positioning airbag, the two sides of the positioning pad can be tilted upward to form an ergonomic U-shaped structure, which tightly wraps the two sides of the child's body to fix the child. When using the lower limb exercise unit to exercise the child's lower limbs, it can effectively prevent the child's body from moving, ensure that the exercise movements are accurate and in place, and greatly improve the efficiency and quality of rehabilitation training.

[0007] The flexible adjustment of the inflation volume of the positioning airbag gives the positioning cushion a strong universal advantage. Whether it is a petite young child or a slightly larger older child, the positioning cushion can be perfectly fitted to the body contours of different children and achieve an ideal fixation effect by only fine-tuning the inflation volume of the positioning airbag according to the actual situation. Compared with traditional bandage or drawstring fixation methods, the airbag fixation method is not only simple and quick to operate, but also provides a stable fixation while cleverly avoiding the formation of strangulation marks or pressure pain on the delicate skin of the child, greatly improving the comfort of the child throughout the rehabilitation training, and prompting the child to cooperate more actively with long-term rehabilitation treatment.

[0008] The carefully placed pressure-adjustable massage airbag in the middle of the positioning pad plays a key role in the child's exercise process. The massage airbag is inflated and deflated in an orderly manner, providing appropriate massage stimulation to the child's waist and back, promoting blood circulation and relieving muscle tension in the waist and back. This massage method not only helps improve the overall rehabilitation effect of the child, but also improves the child's comfort and compliance.

[0009] In terms of ventilation and heat dissipation, the No. 1 ventilation hole under the positioning pad and the No. 2 ventilation hole on the positioning pad can effectively improve the ventilation conditions on the child's back and reduce the stuffiness caused by sweating. This design not only improves the child's use experience, but also avoids skin problems caused by local humid environment.

[0010] In addition, the filling inside the positioning cushion not only provides soft and comfortable support, but also has good cushioning properties, which can evenly disperse the pressure on the child's body, further improving the child's lying comfort and reducing physical fatigue caused by long-term bed rest and exercise.

[0011] In summary, the present invention innovatively integrates the functions of fixation, massage, ventilation and comfortable support. The cleverly designed positioning airbag solves the problem of easy movement of the child's body during exercise. The massage airbag significantly improves the blood circulation in the waist and back. The carefully arranged air holes improve the ventilation and heat dissipation effect. In addition, the comfortable experience brought by the filling material improves the practicality and comfort of the equipment in all aspects, providing a new and efficient solution for the rehabilitation treatment of children with cardiology.

[0012] Furthermore, it also includes an air pressure regulating unit, which includes an inflation device, and the air outlet of the inflation device is connected to an air intake main pipe, the positioning airbags on the No. 1 positioning part are interconnected, and the positioning airbags on the No. 2 positioning part are also interconnected. The positioning airbag of the No. 1 positioning part is connected to the No. 1 air intake branch pipe, and the No. 1 one-way valve and No. 1 pressure gauge are installed on the No. 1 air intake branch pipe; the positioning airbag of the No. 2 positioning part is connected to the No. 2 air intake branch pipe, and the No. 2 air intake branch pipe is installed on the No. 2 one-way valve and No. 2 pressure gauge; each massage airbag is connected to the No. 3 air intake branch pipe, and each No. 3 air intake branch pipe is installed with the No. 3 one-way valve and No. 3 pressure gauge; the No. 1 air intake branch pipe, the No. 2 air intake branch pipe and the No. 3 air intake branch pipe are all connected to the air intake main pipe; the positioning airbag of the No. 1 positioning part, the positioning airbag of the No. 2 positioning part and each massage airbag are connected to an exhaust pipe, and the exhaust pipe is installed with an exhaust valve.

[0013] The beneficial effects of this solution are as follows: Due to the setting of the air pressure regulating unit, the inflatable equipment in this technical solution supplies air uniformly through the air intake main pipe, and the No. 1 air intake branch pipe, the No. 2 air intake branch pipe, and the No. 3 air intake branch pipe are respectively connected to the corresponding airbags, and cooperate with the No. 1 one-way valve, the No. 2 one-way valve, and the No. 3 one-way valve to prevent gas backflow and ensure stable air pressure. The No. 1 pressure gauge, the No. 2 pressure gauge, and the No. 3 pressure gauge can accurately display the air pressure of each airbag in real time, which is convenient for medical staff to control at any time. At the same time, the existence of the exhaust pipe and the exhaust valve enables it to quickly discharge excess gas when deflation is needed. This design is convenient for flexible adjustment of the airbag pressure according to the specific situation of the child to ensure good fixation and massage effects, and can also avoid excessive air pressure, significantly improving the safety and user experience of rehabilitation equipment.

[0014] Furthermore, there are two lower limb exercise units, which are symmetrically installed on the rehabilitation bed. Each lower limb exercise unit includes a connecting column. A mounting groove is provided on the side of the rehabilitation bed. The connecting column is fixedly connected in the mounting groove. A slider No. 1 and a slider No. 2 are slidably provided on the connecting column. A foot pedal is connected to the top of the slider No. 1. An elastic member is sleeved on the connecting column between the slider No. 1 and the slider No. 2. One end of the elastic member is fixedly connected to the slider No. 1, and the other end is fixedly connected to the slider No. 2. A locking unit is provided on the slider No. 2, and the locking unit can lock the slider No. 2.

[0015] The beneficial effects of this solution are as follows: Due to the setting of the locking unit, this technical solution can lock the position of the No. 2 slider. When exercising the child, the child's waist and back lie on the waist and back positioning unit, and the feet are placed on the foot pedals for exercise. Medical staff can accurately adjust the position of the No. 2 slider according to the specific conditions of the child's legs, such as muscle strength, joint mobility, etc., so as to customize the initial tension of the elastic part. This means that rehabilitation training can better fit the physical condition of each child and greatly improve the rehabilitation effect. In addition, children of different ages and body shapes can find a suitable exercise position through the locking unit, ensuring the comfort and effectiveness of the exercise, and improving the applicability of the equipment.

[0016] The two symmetrically distributed lower limb training units can also train both legs simultaneously, promote the balanced development of the children's lower limb muscles, prevent muscle strength imbalance caused by unilateral training, and help children fully recover their body functions.

[0017] Furthermore, the foot pedal includes a fixed plate, on which a telescopic plate is slidably arranged, and the telescopic plate can extend outward toward the middle of the rehabilitation bed.

[0018] The beneficial effect of this solution is that due to the setting of the telescopic plate, the position of the foot pedal can be adjusted in the width direction of the rehabilitation bed, and the locking unit can adjust the position of the foot pedal in the length direction of the rehabilitation bed. This design greatly improves the adaptability of the foot pedal. Whether it is a petite young child or a slightly larger older child, they can find the foot pedal position that best suits their physical conditions through the coordinated adjustment of the telescopic plate and the locking unit.

[0019] Different children have different leg lengths and hip widths. Precise position adjustment can ensure that children's feet can be comfortably and stably placed on the pedals during exercise, and the force can be more natural and smooth. This not only helps to improve the comfort of exercise, but also avoids posture errors caused by improper pedal position, effectively improves the exercise effect, and provides strong support for the rehabilitation training of more children in the Department of Cardiology.

[0020] Furthermore, a buffer block is fixedly connected to one side of the mounting groove close to the first sliding block.

[0021] The beneficial effect of this solution is that when the child is exercising on the pedal, the force exerted by the leg will cause the No. 1 slider to rush quickly to the edge of the installation slot, generating a large impact force. The existence of the buffer block can buffer this force in advance, not only preventing the slider from being damaged by the impact, but more importantly, preventing the vibration from being transmitted to the pedal, preventing the child's feet and legs from being accidentally injured, and effectively ensuring the safety of exercise. At the same time, the buffer block allows the No. 1 slider to move more smoothly and smoothly. When the child is doing leg flexion and extension movements, there will be no jamming due to collisions, and the child can train more attentively and comfortably, thereby better cooperating with rehabilitation treatment.

[0022] Furthermore, a receiving groove is provided on the rehabilitation bed, a No. 1 ventilation hole is arranged at the bottom of the receiving groove, a positioning pad is placed in the receiving groove, and a size of the positioning pad is smaller than a size of the receiving groove.

[0023] The beneficial effects of this solution are: the receiving groove provides precise positioning for the positioning pad, preventing it from shifting during use, and ensuring stable fixation. The No. 1 ventilation hole is at the bottom of the groove, and cooperates with the No. 2 ventilation hole of the positioning pad to form good convection, which can more efficiently discharge the hot and humid air on the back of the child. Moreover, this design makes it easy to take out the positioning pad for cleaning, effectively maintaining the hygiene of the equipment and reducing the risk of cross infection.

[0024] Furthermore, a heater is installed on the air intake main pipe.

[0025] The beneficial effects of this solution are as follows: Due to the setting of the heater, this technical solution can heat the gas entering the positioning airbag and the massage airbag, thereby providing a warm and comfortable experience for the child in cold weather or when the child is weak. The warm gas contacts the child's body, which can effectively relieve muscle tension that may be caused by low temperature, making the child more relaxed during rehabilitation training.

[0026] From a physiological perspective, the heated gas entering the airbag can promote local blood circulation, especially in the area where the waist and back are in contact with the airbag. This not only helps to enhance the massage effect of the massage airbag and better relieve muscle fatigue, but also accelerates the delivery of nutrients and the discharge of metabolic waste, further accelerating the recovery process of the child.

[0027] In addition, the appropriate temperature can prevent some discomfort caused by cold stimulation, such as the risk of colds, create a more favorable internal and external environment for the recovery of children, and comprehensively improve the functionality of rehabilitation equipment and the use experience of children.

[0028] Furthermore, it also includes a control unit, which includes a controller, and the No. 1 one-way valve, the No. 2 one-way valve, the No. 3 one-way valve, the exhaust valve, the No. 1 pressure gauge, the No. 2 pressure gauge, and the No. 3 pressure gauge are all electrically connected to the controller.

[0029] The beneficial effects of this solution are: when it is necessary to inflate the positioning airbag, the inflation device is turned on, the controller controls the No. 1 and No. 2 check valves to open, and the positioning airbag is inflated. When the gas pressure in the positioning airbag reaches the preset value, the No. 1 and No. 2 pressure gauges feed back the pressure information to the controller, and the controller controls the No. 1 and No. 2 check valves to close. This process realizes the automation and precision of the inflation process, greatly reduces the operating burden of medical staff, and avoids the pressure error that may occur in manual operation.

[0030] When massage is needed, the controller controls the corresponding No. 3 check valve to open, and at the same time, accurately adjusts the inflation and deflation rhythm of the massage airbag according to the pressure data fed back by the No. 3 pressure gauge. By dynamically adjusting the pressure of the massage airbag, a variety of massage modes can be simulated to meet the personalized needs of different children and significantly improve the massage effect.

[0031] When the gas pressure in the positioning airbag and massage airbag needs to be adjusted, the controller responds quickly. The exhaust valve is accurately controlled to open so that the gas in the airbag can be discharged in an orderly manner. During this process, pressure gauges No. 1, No. 2, and No. 3 monitor the airbag pressure in real time. Once the pressure reaches the preset ideal value, the pressure gauge immediately feeds back the pressure information to the controller, and the controller immediately issues a command to control the exhaust valve to close, completing the precise adjustment of the gas pressure.

[0032] Furthermore, it also includes a counter. A placement groove is provided on the installation groove near the side of the first slide block. A linear position sensor is installed in the placement groove. The linear position sensor and the counter are both electrically connected to the controller.

[0033] The beneficial effect of this solution is that the linear position sensor can accurately monitor the moving position of slider No. 1 on the connecting column. When the child uses the foot pedal to exercise, every movement of slider No. 1 will be accurately captured by the linear position sensor. These position data are transmitted to the controller in real time. The controller converts the position change into a specific number of exercise movements according to the set algorithm and passes it to the counter. For example, a complete leg flexion and extension movement corresponds to the process of slider No. 1 moving from the starting point to the end point and then returning to the starting point. The counter accurately records this process as one time. In this way, medical staff can obtain accurate quantitative data of the child's rehabilitation training and clearly understand the child's exercise progress. Furthermore, they can tailor a more scientific and targeted personalized rehabilitation plan based on the number of exercises recorded by the counter, combined with the child's physical condition and rehabilitation goals.

[0034] Furthermore, each lower limb exercise unit is provided with a support auxiliary unit, one of which can intermittently inflate the positioning airbag of the No. 1 positioning part, and the other support auxiliary unit can intermittently inflate the positioning airbag of the No. 2 positioning part.

[0035] The beneficial effects of this solution are as follows: considering that the child is relatively weak, the design of the support auxiliary unit in this technical solution plays an important role when exercising his lower limbs. When exercising the lower limb on the same side as the No. 1 positioning part, one of the support auxiliary units will inflate the positioning airbag of the No. 1 positioning part. As the amount of gas gradually increases, the positioning airbag of the No. 1 positioning part can provide strong support for the child, prompting the child's body to tilt moderately toward the side close to the No. 2 positioning part, thereby assisting the child to successfully complete the exercise of the lower limb on that side. When the exercise of the lower limb on that side is completed, open the exhaust valve on the positioning airbag of the No. 1 positioning part to exhaust the gas in the airbag and restore it to its initial positioning state. When exercising the lower limb on the other side of the child, the process is the same, that is, another support auxiliary unit is used to inflate the positioning airbag of the No. 2 positioning part to help the child complete the exercise of the lower limb on the other side.

[0036] The support auxiliary unit is cleverly linked to the lower limb exercise movements, and can automatically and accurately adjust the inflation volume of the positioning airbag according to the movement state of the child's lower limbs. When the child is exercising, it provides real-time and appropriate lateral support for the body. In this way, the possibility of deformation of movements or interruption of exercise during exercise due to insufficient strength of the child is greatly reduced, making rehabilitation training safer and more efficient, thereby effectively shortening the rehabilitation cycle. At the same time, the support auxiliary unit helps the child complete the exercise movements, reduces the burden of the child's own exertion, avoids muscle soreness or fatigue caused by excessive exertion, and enables the child to perform rehabilitation training in a comfortable state, thereby significantly improving the child's acceptance and cooperation with rehabilitation treatment.

In this embodiment, the inflation device 22 uses an air pump. It should be noted that for the convenience of illustration, Figure 5 The number of the No. 1 positioning airbag 18, the No. 2 positioning airbag 34 and the massage airbag 19 is one, but not limited to this.

[0056] The specific implementation process is as follows:

[0057] When performing lower limb rehabilitation exercises for children, first let the children lie on the positioning pad 16 with their waist and back. According to the height and body shape of the children, the medical staff adjusts the position of the foot pedal 6 in the width direction of the rehabilitation bed 1 through the telescopic plate 12, and uses the locking unit to adjust the position of the foot pedal 6 in the length direction to ensure that the foot pedal 6 fits the child's body. Subsequently, the child's feet are fixed to the foot pedal 6 with a connecting belt. Next, start the air pump to inflate the No. 1 positioning airbag 18 and the No. 2 positioning airbag 34, so that the two sides of the positioning pad 16 are tilted to form an ergonomic U-shaped structure, tightly wrapping the two sides of the child's body to fix the child. At this point, the child can exercise on the lower limb exercise unit. At the same time, the massage airbag 19 is inflated and deflated in an orderly manner according to the procedure to massage the child's waist and back, promote blood circulation, relieve muscle tension, and help rehabilitation training to be carried out efficiently.

[0058] Example 2

[0059] On the basis of Example 1, a heater is installed on the air intake main pipe 23, which can heat the gas entering the No. 1 positioning airbag 18, the No. 2 positioning airbag 34 and the massage airbag 19. In cold weather or when the child is weak, the warm gas contacts the child, which can relieve muscle tension and make him more relaxed during rehabilitation training. From a physiological point of view, it promotes local blood circulation in the waist and back, enhances the effect of the massage airbag 19, accelerates nutrient delivery and waste discharge, and promotes the rehabilitation process. Moreover, the appropriate temperature can reduce the discomfort caused by cold stimulation, such as the risk of colds, and enhance the rehabilitation experience.

[0060] Example 3

[0061] On the basis of Example 1 or Example 2, a control unit is further included, the control unit includes a controller, and the No. 1 check valve 25, the No. 2 check valve 36, the No. 3 check valve 28, the exhaust valve 31, the No. 1 pressure gauge 26, the No. 2 pressure gauge 37, and the No. 3 pressure gauge 29 are all electrically connected to the controller. In this embodiment, the No. 1 pressure gauge 26, the No. 2 pressure gauge 37, and the No. 3 pressure gauge 29 are all electric contact pressure gauges, and the controller uses a single chip microcomputer of model STM32.

[0062] When it is necessary to inflate the No. 1 positioning airbag 18 and the No. 2 positioning airbag 34, the inflating device 22 is turned on, and the controller controls the No. 1 check valve 25 and the No. 2 check valve 36 to open, and inflate the No. 1 positioning airbag 18 and the No. 2 positioning airbag 34. When the gas pressure in the No. 1 positioning airbag 18 and the No. 2 positioning airbag 34 reaches the preset value, the No. 1 pressure gauge 26 and the No. 2 pressure gauge 37 feed back the pressure information to the controller, and the controller controls the No. 1 check valve 25 and the No. 2 check valve 36 to close. This process realizes the automation and precision of the inflation process, greatly reduces the operating burden of medical staff, and avoids the pressure error that may occur in manual operation.

[0063] When massage is needed, the controller controls the corresponding No. 3 check valve 28 to open, and at the same time, according to the pressure data fed back by the No. 3 pressure gauge 29, accurately adjusts the inflation and deflation rhythm of the massage airbag 19. By dynamically adjusting the pressure of the massage airbag 19, a variety of massage modes can be simulated to meet the personalized needs of different children and significantly improve the massage effect.

[0064] When the gas pressure in the No. 1 positioning airbag 18, the No. 2 positioning airbag 34 and the massage airbag 19 needs to be adjusted, the controller responds quickly. The exhaust valve 31 is accurately controlled to open so that the gas in the airbag can be discharged in an orderly manner. During this process, the No. 1 pressure gauge 26, the No. 2 pressure gauge 37 and the No. 3 pressure gauge 29 monitor the airbag pressure in real time. Once the pressure reaches the preset ideal value, the pressure gauge immediately feeds back the pressure information to the controller, and the controller immediately issues an instruction to control the exhaust valve 31 to close, completing the precise adjustment of the gas pressure.

[0065] Example 4

[0066] On the basis of Example 3, Figure 6 As shown, a counter is also included. A placement slot 32 is opened on the left side of the installation slot 3. A linear position sensor 33 is installed in the placement slot 32. The linear position sensor 33 and the counter are both electrically connected to the controller. The linear position sensor 33 can accurately monitor the moving position of the first slider 4 on the connecting column 2. In this embodiment, the model of the linear position sensor 33 is PositekP103.

[0067] When the child uses the foot pedal 6 to exercise, every movement of the slider 4 will be accurately captured by the linear position sensor 33. These position data are transmitted to the controller in real time. The controller converts the position change into a specific number of exercise movements according to the set algorithm and passes it to the counter. For example, a complete leg flexion and extension movement corresponds to the process of the slider 4 from the starting point to the end point and then returning to the starting point. The counter accurately records this process as one time. In this way, medical staff can obtain accurate quantitative data of the child's rehabilitation training and clearly understand the child's exercise progress. Furthermore, they can tailor a more scientific and targeted personalized rehabilitation plan based on the number of exercises recorded by the counter, combined with the child's physical condition and rehabilitation goals.

[0068] Example 5

[0069] On the basis of Example 1 or Example 2 or Example 3 or Example 4, each lower limb exercise unit is provided with a support auxiliary unit, the support auxiliary unit on the rear side of the rehabilitation bed 1 can intermittently inflate the No. 1 positioning airbag 18, and the support auxiliary unit on the front side of the rehabilitation bed 1 can intermittently inflate the No. 2 positioning airbag 34. Take the support auxiliary unit on the rear side of the rehabilitation bed 11 as an example for explanation, Figure 7As shown, the support auxiliary unit includes a piston rod 38, a piston and a piston cylinder 39. The piston rod 38 is glued to the right side of the No. 1 slider 4, and the piston is welded to the right end of the piston rod 38. The outer circumferential surface of the piston is provided with a rubber sealing ring, and the piston seal is slidably arranged in the piston cylinder 39. The piston cylinder 39 is installed at the bottom of the mounting groove 3 by bolts. The right side of the piston cylinder 39 is connected to an air outlet pipe, and a No. 4 one-way valve is installed on the air outlet pipe. The right end of the air outlet pipe is connected to one of the No. 1 positioning air bags 18. In order to prevent the support auxiliary unit from interfering with the sliding of the No. 2 slider 5, a U-shaped hole 40 is opened on the No. 2 slider 5, and the support auxiliary unit can pass through the U-shaped hole 40.

[0070] When exercising the right lower limb of the child, considering that the child is relatively weak, during the exercise, the child's foot drives the No. 1 slider 4 to move to the right. At this time, the piston will move to the right synchronously in the piston cylinder 39, open the No. 4 one-way valve, and inflate the No. 1 positioning airbag 18, so that the gas volume of the No. 1 positioning airbag 18 gradually increases. After the gas volume of the No. 1 positioning airbag 18 increases, it can provide strong support for the right side of the child, so that the child's body tilts moderately to the left, thereby assisting the child to successfully complete the exercise of the right lower limb. After the exercise of the right lower limb is completed, the exhaust valve 31 on the No. 1 positioning airbag 18 is opened to discharge the gas in the airbag and restore it to its initial positioning state. The process of exercising the left lower limb of the child is consistent with the exercise process of the right lower limb. The No. 2 positioning airbag 34 is inflated through the support auxiliary unit on the front side of the rehabilitation bed 1 to assist the child to complete the exercise of the left lower limb.

[0071] The support auxiliary unit is cleverly linked to the lower limb exercise movements, and can automatically and accurately adjust the inflation volume of the No. 1 positioning airbag 18 and the No. 2 positioning airbag 34 according to the movement state of the child's lower limbs. When the child is exercising, it provides real-time and appropriate lateral support for the body. In this way, the possibility of movement deformation or exercise interruption during exercise due to insufficient strength of the child is greatly reduced, making rehabilitation training safer and more efficient, thereby effectively shortening the rehabilitation cycle. At the same time, the support auxiliary unit helps the child complete the exercise movements, reduces the burden of the child's own exertion, avoids muscle soreness or fatigue caused by excessive exertion, and enables the child to perform rehabilitation training in a comfortable state, thereby significantly improving the child's acceptance and cooperation with rehabilitation treatment.
