Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically to a dynamic and static balance training device with pneumatic auxiliary support. Background Technology

[0002] Rehabilitation training refers to physical activities that promote recovery or improvement of function after injury. Appropriate and scientific physical exercises play a positive role in the rapid healing of injuries and the promotion of functional recovery. Through rehabilitation training, muscle atrophy and contractures can be prevented, the mobility of healthy limbs can be improved, and good cardiopulmonary function can be maintained. Balance function is a fundamental motor skill. Patients with neurological diseases often exhibit varying degrees of balance dysfunction. Therefore, balance training equipment is needed to train and assess patients' balance abilities, improve their balance, and perform functional measurements of balance during training. This helps doctors determine whether physical therapy, support or assistive devices, or other interventions are necessary to improve balance.

[0003] Balance training equipment is divided into balance equipment for active assessment and training and balance training equipment for passive training. To prevent patients from falling during balance training, protective measures are usually added to balance training equipment to protect patients and ensure that they can complete the balance training. The protective measures used in existing balance training equipment are mostly straps, handrails and slings. Although they can provide some protection for patients, due to the poor balance ability of patients themselves, patients may still fall after a long period of balance training. The safety is low and it will also affect the balance assessment and training effect. Summary of the Invention

[0004] To address the issue of low safety in the protective measures employed in existing balance training equipment, this invention provides a dynamic and static balance training device with pneumatic auxiliary support. This balance training device has auxiliary support function, high safety, and can provide comprehensive protection for patients, making balance training safer for them; at the same time, it allows patients to conduct balance ability assessments even when their muscle strength is low.

[0005] To achieve the above objectives, the technical solution of this utility model is: a dynamic and static balance training device with pneumatic auxiliary support, comprising a base, an auxiliary support unit, and a dynamic and static balance training mechanism disposed within the base, the upper part of which extends to the outside of the base; the auxiliary support unit includes a front support seat, a rear support door, and an inner support cylinder, the front support seat being disposed on the outside of the base, and the front support seat and the rear support door being detachably connected, the inner support cylinder being disposed on the top of the base, and an openable and closable annular airbag being disposed in the gap between the inner support cylinder and the front support seat and the rear support door. The dynamic and static balance training mechanism is used for patients to perform balance training and to assess their balance ability. The annular airbag provides protection for patients during balance training and also provides auxiliary support; the front support seat and the rear support door limit the movement of the annular airbag, and the rear support door facilitates the patient's entry into the annular airbag.

[0006] A drive unit is located on one side of the base. The drive unit includes an air supply assembly and a control module. The air supply assembly includes an air pump and an air tank, a proportional valve, and a directional valve connected in sequence via pipelines. The control module controls the air supply assembly to supply air to the annular airbag and the dynamic and static balance training mechanism. The air pump and air tank are used to inflate the annular airbag through pipelines. The air tank ensures a stable air flow and pressure into the annular airbag, and the proportional valve detects the air pressure inside the airbag.

[0007] Preferably, a mounting hole is provided at the center of the top of the base, and the upper part of the dynamic and static balance training mechanism passes through the mounting hole and extends to the outside of the base. The purpose of the mounting hole is to allow the upper part of the dynamic and static balance training mechanism to extend to the outside of the base, thereby facilitating the patient to stand on the dynamic and static balance training mechanism to perform balance training and balance ability assessment.

[0008] Preferably, the inner sides of both the front support base and the rear support door are arc-shaped. Two pin cylinders are symmetrically provided at both ends of the inner side of the front support base. The inner end of the rear support door is located between the two pin cylinders. A pin is inserted through the rear support door on the two pin cylinders. The rear support door is installed on the front support base by the cooperation of the pin, the pin cylinder and the rear support door. The rear support door and the front support base limit the annular airbag. At the same time, one of the pins can be removed to rotate and open the rear support door, so that the patient can enter the annular airbag.

[0009] Preferably, the bottom of the inner support cylinder has a through hole for the upper part of the dynamic and static balance training mechanism to pass through. The outer diameter of the inner support cylinder is smaller than the diameter of the inner arc-shaped structure of the front support seat and the rear support door. The purpose is to create a gap between the inner support cylinder and the front support seat and the rear support door to provide an installation position for the annular airbag.

[0010] Preferably, the drive unit further includes a drive housing, and a square hole is provided at the bottom of the outer side of the front support base. One end of the drive housing passes through the square hole and is connected to the base. The square hole facilitates the installation of the drive housing on the base.

[0011] Preferably, the air supply component and control module are located inside the drive housing. The air pump is connected to the air storage tank through a pipeline, and the reversing valve is connected to the annular airbag through a pipeline. The reversing valve can enable the air pump and the air storage tank to supply air to the annular airbag and the dynamic and static balance mechanism respectively, and can also enable the annular airbag to release air.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] 1. This utility model has a reasonable structure and good performance. It has auxiliary support function, high safety, and can provide comprehensive protection for patients when they do balance training. It makes patients safer when doing balance training and avoids the phenomenon of falling after long-term balance training. It can also enable patients to conduct balance ability assessment when their muscle strength is low.

[0014] 2. This utility model uses an adjustable pressure ring airbag to replace existing protective measures. The ring airbag's full-enclosure design makes it safer for patients to perform balance training, ensuring high safety. When the patient's muscle strength is low, the ring airbag can be used as an auxiliary support, while as the patient's muscle strength gradually increases, the ring airbag can play a safety protection role. Because the ring airbag is used as an auxiliary support, the patient will feel safer and more willing to train, thereby improving the training effect.

[0015] 3. This utility model detects the pressure parameters of the annular airbag through a proportional valve and inputs the pressure parameters into the control module. The annular airbag provides auxiliary support to the patient. The annular airbag and the system share a unified airway system. Patients with low muscle strength can use the pressure of the annular airbag to assess their balance ability.

[0016] 4. The air supply component of the drive unit of this utility model can provide air to the annular airbag and the dynamic and static balance training mechanism, so as to achieve the effect of the annular airbag protecting the patient and the dynamic and static balance training mechanism completing balance training. The air pump, in cooperation with the air tank, can provide a stable air flow and pressure to the annular airbag or the dynamic and static balance training mechanism, ensuring that the air pressure and flow remain stable during the inflation process; while the proportional valve can detect the pressure of the annular airbag and the dynamic and static balance training mechanism system.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-5 As shown, a dynamic and static balance training device with pneumatic auxiliary support includes a base 2, an auxiliary support unit, and a dynamic and static balance training mechanism 1 disposed within the base 2. The upper part of the dynamic and static balance training mechanism 1 extends to the outside of the base 2. The auxiliary support unit includes a front support seat 3, a rear support door 6, and an inner support cylinder 7. The front support seat 3 is disposed on the outside of the base 2, and the front support seat 3 and the rear support door 6 are detachably connected. The inner support cylinder 7 is disposed on the top of the base 2, and an openable and closable annular airbag 8 is disposed in the gap between the inner support cylinder 7 and the front support seat 3 and the rear support door 6. The base 2 is a hollow shell structure that provides an installation position for the dynamic and static balance training mechanism 1, the front support seat 3, the inner support cylinder 7, and the annular airbag 8. The gap between the inner support cylinder 7 and the front support seat 3 and the rear support door 6 is for the purpose of installing the annular airbag 8. The inner support cylinder 7, the front support seat 3, and the rear support door 6 limit the annular airbag 8 to prevent it from tipping over when providing auxiliary support to the patient. The annular airbag 8 can be opened and closed. It can be opened from the rear and uses the same air passage as the system to facilitate the patient's entry into the annular airbag 8. After the annular airbag 8 is inflated, the uppermost and lowermost layers of the annular airbag 8 can be connected by adhesive or binding.

[0025] A drive unit is provided on one side of the base 2. The drive unit includes an air supply component and a control module 13. The air supply component includes an air pump and an air storage tank 10, a proportional valve 11 and a reversing valve 12 connected in sequence through pipelines. The control module 13 is used to control the air supply component to supply air to the annular airbag 8 and the dynamic and static balance training mechanism 1. In this embodiment, the dynamic and static balance training mechanism 1 is a Chinese invention patent with authorization announcement number CN113082613B, applicable to a three-dimensional dynamic standing training balance assessment device. The control module 13 is a control module applicable to a three-dimensional dynamic standing training balance assessment device. The control module 13 can control the air supply component to supply air to the annular airbag 8, the airbag of the dynamic and static balance training mechanism 1, and the cylinder. The effect of supplying air to the annular airbag 8, the airbag of the dynamic and static balance training mechanism 1, and the cylinder is achieved through the action of the reversing valve 12. It can also release air from the annular airbag 8. The proportional valve 11 detects the air pressure parameter of the annular airbag 8 and transmits the pressure parameter to the control module 13. The control module 13 performs proportional algorithm calculation and analysis based on the pressure parameter to obtain the auxiliary support force of the annular airbag 8. The patient's weight minus the auxiliary support force is the support force of the dynamic and static balance training mechanism 1. The control module 13 performs algorithm analysis based on the received detection information of the dynamic and static balance training mechanism 1 to obtain the patient's balance ability detection result.

[0026] An installation hole is provided at the center of the top of the base 2. The upper part of the dynamic and static balance training mechanism 1 passes through the installation hole and extends to the outside of the base 2. The installation hole allows the upper part of the dynamic and static balance training mechanism 1 to extend to the outside of the base 2, so that the patient can stand on the dynamic and static balance training mechanism 1 to perform balance training and balance ability assessment.

[0027] Both the front support base 3 and the rear support door 6 have an arc-shaped inner side. Two pin cylinders 4 are symmetrically arranged at both ends of the inner side of the front support base 3. The inner end of the rear support door 6 is located between the two pin cylinders 4. A pin 5 is inserted into each of the two pin cylinders 4, penetrating the rear support door 6. The arc-shaped inner sides of both the front support base 3 and the rear support door 6 facilitate the limiting of the annular airbag 8. By inserting the pin 5 through the two pin cylinders 4 and the rear support door 6, the rear support door 6 is installed onto the front support base 3, ensuring that the front support base 3 and the rear support door 6 work together to limit the annular airbag 8. When one of the pins 5 is removed, the rear support door 6 can be rotated, facilitating the patient's entry into the annular airbag 8.

[0028] The bottom of the inner support cylinder 7 has a through hole for the upper part of the dynamic and static balance training mechanism 1 to pass through, so that the patient can stand on the dynamic and static balance training mechanism 1 to perform balance training. The outer diameter of the inner support cylinder 7 is smaller than the diameter of the inner arc-shaped structure of the front support seat 3 and the rear support door 6, so that there is a gap between the inner support cylinder 7 and the front support seat 3 and the rear support door 6 to install the annular airbag 8.

[0029] The drive unit also includes a drive housing 9. A square hole is provided at the bottom of the outer side of the front support 3. One end of the drive housing 9 passes through the square hole and is connected to the base 2. The drive housing 9 has an L-shaped shell structure with a hollow interior.

[0030] The air supply assembly and control module 13 are located inside the drive housing 9. The air pump is connected to the air storage tank 10 via a pipeline, and the reversing valve 12 is connected to the annular airbag 8 via a pipeline. The combination of the air pump and the air storage tank 10 can provide a stable airflow and pressure to the annular airbag 8 or the dynamic and static balance training mechanism 1. The air pump delivers air to the air storage tank 10 via a pipeline, and then delivers it to the annular airbag 8 or the airbag or cylinder of the dynamic and static balance training mechanism 1 via the proportional valve 11 and the reversing valve 12.

[0031] The working principle of this utility model is as follows: First, one of the pins 5 is pulled out from the pin cylinder 4 and the rear support door 6, and the rear support door 6 is opened by rotation. The patient enters the annular airbag 8 and stands on the dynamic and static balance training mechanism 1. Then, the rear support door 6 is closed by rotation again, and the pin 5 is inserted into the pin cylinder 4 and the rear support door 6. The control module 13 controls the air supply component to inflate the annular airbag 8. The air pump pumps air into the air tank 10. The air passes through the pipeline and sequentially through the proportional valve 11 and the reversing valve 12 to inflate the annular airbag 8. The proportional valve 11 detects the pressure parameters of the annular airbag 8. The operator adjusts the corresponding pressure according to the patient's condition and transmits the pressure parameters to the control module 13. Then, the patient can perform balance training and balance ability assessment through the dynamic and static balance training mechanism 1. When the patient's muscle strength is low, the patient can hold the annular airbag 8 for auxiliary support. As the patient's muscle strength gradually increases, the annular airbag 8 plays a safety protection role. After the patient completes the balance training, the air in the annular airbag 8 is released through the reversing valve 12, and then the rear support door 6 is opened to allow the patient to exit the annular airbag 8.

[0032] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
