DETAILED DESCRIPTION

[0018] The following examples are for illustrative purposes only and are not intended to limit the scope of the application.

[0019] As Figures 1-5 shown, the application provides a stroke rehabilitation balance testing device, which can include a support plate 1, a support frame 2, a seat 3, a testing mechanism 5 and a protection mechanism 6.

[0020] The support frame 2 is fixedly connected to the top of the support plate 1, and the seat 3 is installed on one side of the top of the support plate 1.

[0021] It should be noted that the fixed connection mode of the support frame 2 and the support plate 1 described in the embodiment can provide a stable installation carrier for the subsequent protection mechanism 6, avoid shaking of the protection mechanism 6 when triggered to work due to unstable support, and ensure accurate protection action. The seat 3 arranged on one side of the top of the support plate 1 can facilitate the stroke patient to sit down nearby for rest or test preparation before testing, without long-distance movement, which is in line with the characteristics of weak movement ability of stroke patients, reduces the test obstacles caused by inconvenient movement of patients, and also enables the patients to quickly recover their strength during the test interval, thereby improving the safety and comfort of the overall test process.

[0022] The testing mechanism 5 includes a support table 51, a placement sleeve plate 52, a support bottom plate 53, an assembly bottom plate 54 and a monitoring assembly 55.

[0023] The side wall of the support plate 1 is provided with a mounting groove 11.

[0024] It should be noted that the mounting groove 11 of the side wall of the support plate 1 described in this embodiment can accommodate the assembly bottom plate 54 and the monitoring assembly 55 in the internal space of the support plate 1, avoiding the exposure of the monitoring assembly 55 to the external environment, preventing the monitoring assembly 55 from being affected by collision, dust accumulation, etc., prolonging the service life of the monitoring assembly 55, and also making the overall structure of the support plate 1 more regular, avoiding the influence of external protruding structures on the movement and standing of the patient on the support plate 1, and ensuring the safety of the patient's activities during the test.

[0025] The support table 51 is fixedly connected to the top of the support plate 1, and the two placement sleeve plates 52 are symmetrically and slidingly connected to the top of the support table 51. The support bottom plate 53 is fixedly connected to the bottom of the placement sleeve plate 52.

[0026] It should be noted that the fixed connection of the support bottom plate 53 and the placement sleeve plate 52 described in this embodiment can stably transmit the pressure generated by the change of the patient's weight and center of gravity supported by the placement sleeve plate 52 to the monitoring assembly 55 below, ensuring that the monitoring assembly 55 can accurately capture the pressure signal.

[0027] The assembly bottom plate 54 is fixedly connected to the inner bottom of the mounting groove 11. The monitoring assembly 55 is arranged between the top of the assembly bottom plate 54 and the bottom of the support bottom plate 53 and is connected through the monitoring assembly 55.

[0028] It should be noted that the assembly bottom plate 54 described in this embodiment is fixedly connected to the inner bottom of the mounting groove 11, which can provide a stable and fixed installation reference for the monitoring assembly 55, prevent the monitoring assembly 55 from deviating due to the shaking of the installation position, and ensure the reliability of the monitoring data. The structure of the monitoring assembly 55 connecting the assembly bottom plate 54 and the support bottom plate 53 can form a complete pressure transmission path, allowing the pressure change on the placement sleeve plate 52 to be directly transmitted to the monitoring assembly 55 through the support bottom plate 53, so that the monitoring assembly 55 can accurately perceive the change of the center of gravity when the patient stands, providing accurate data support for subsequent balance ability evaluation and triggering of the protection mechanism 6.

[0029] The protection mechanism 6 is installed on the support frame 2.

[0030] It should be noted that the protection mechanism 6 described in this embodiment is installed on the support frame 2, which utilizes the stability of the support frame 2 to ensure that the protection mechanism 6 is in the lateral protection position during the patient standing test. When the patient loses balance, the protection mechanism 6 can quickly respond from the side to prevent the patient from falling to both sides. At the same time, the assembly method of the protection mechanism 6 and the support frame 2 also facilitates the subsequent maintenance or replacement of the protection mechanism 6, without the need for substantial disassembly of the support plate 1 and the test mechanism 5, reducing the maintenance difficulty and ensuring the use efficiency of the overall device.

[0031] Specifically, the patient can first sit on the seat 3 on one side of the top of the support plate 1 for pre-test preparation or rest, reducing the burden of movement due to difficulty in moving. When standing for testing, the patient can place both feet on the two symmetrically placed sleeve plates 52 on the top of the support platform 51. The position of the sleeve plate 52 can be adjusted according to the distance between the two feet to ensure stable standing. The pressure generated by the patient's body weight and the change of the center of gravity is borne by the sleeve plate 52 and transmitted to the monitoring assembly 55 on the top of the assembled bottom plate 54 in the side wall mounting groove 11 of the support plate 1 through the bottom fixedly connected support bottom plate 53. The monitoring assembly 55 senses the pressure change in real time and transmits the signal to the controller 7. During normal testing, the controller 7 evaluates the patient's balance ability according to the pressure data of the monitoring assembly 55. When the patient's body tilts and causes a significant difference in pressure between the two sleeve plates 52, i.e., balance disorder, the controller 7 quickly triggers the protection mechanism 6 installed on the support frame 2 on the top of the support plate 1, so that the protection mechanism 6 starts the protection action to avoid the patient from falling. The mounting groove 11 can accommodate and protect the monitoring assembly 55, ensuring its stable work without external interference. The support frame 2 provides stable support for the protection mechanism 6 to ensure the accuracy of the protection action. The device solves the problems in the background art in the following way: the background art points out that the existing device has the problem of insufficient precision of pressure sensing and protection triggering linkage. Specifically, it does not provide independent pressure sensing units for the patient's feet, making it difficult to capture the differential pressure change of the feet when the body tilts in real time, which leads to delayed or false triggering of the protection mechanism. The device solves this problem by providing independent sleeve plates 52 for the feet, and each sleeve plate 52 forms an independent pressure transmission path with the monitoring assembly 55 on the assembled bottom plate 54 in the mounting groove 11 through the support bottom plate 53. This can accurately capture the differential pressure change of the two sleeve plates 52 when the body tilts, and realize the efficient linkage of "independent pressure sensing of both feet-real-time signal analysis-accurate triggering of the protection mechanism 6" with the controller 7, avoiding the problem of inaccurate pressure capture caused by the lack of independent sensing units in the existing device. The assembled bottom plate 54 provides a stable installation reference for the monitoring assembly 55, preventing the monitoring assembly 55 from deviating in pressure sensing due to shaking. The support frame 2 ensures that the protection mechanism 6 responds stably when triggered, completely solving the problem of delayed or false triggering of the protection mechanism in the existing device, making the balance evaluation data more reliable, and effectively improving the testing safety and evaluation accuracy.

[0032] Further, the monitoring assembly 55 comprises a support arm 551, a support sleeve plate 552, a support spring 553, a contact head 554, a pressure sensor 555 and a lifting head 556, wherein one end of the support arm 551 is fixedly connected to the bottom of the support bottom plate 53, one end of the support sleeve plate 552 is fixedly connected to the top of the assembly bottom plate 54, the other end of the support arm 551 is slidably penetrated through the other end of the support sleeve plate 552, the lifting head 556 is fixedly connected to the inner bottom of the support sleeve plate 552, one end of the plurality of support springs 553 is fixedly connected to the top of the lifting head 556 in a circumferential array, one end of the contact head 554 is fixedly connected to the bottom of the support arm 551, the pressure sensor 555 is installed on the top of the lifting head 556, and the other end of the contact head 554 abuts against the monitoring part of the pressure sensor 555.

[0033] It should be noted that the monitoring assembly 55 described in the embodiment can ensure that the support arm 551 moves only in the vertical direction when the placement sleeve plate 52 is stressed, avoiding lateral deviation that causes pressure transmission deviation, and the plurality of support springs 553 are distributed in a circumferential array on the top of the lifting head 556, which can provide uniform buffer support for the support arm 551, prevent the support arm 551 from being damaged due to excessive instantaneous stress, and prevent the pressure sensor 555 from being damaged, and can drive the support arm 551 and the placement sleeve plate 52 to quickly reset after the pressure disappears, and the close abutment of the contact head 554 and the monitoring part of the pressure sensor 555 can ensure that the pressure signal is transmitted without loss, further improving the pressure sensing accuracy of the monitoring assembly 55.

[0034] Specifically, when the placement sleeve plate 52 bears the pressure generated by the body weight or the change of the center of gravity of the patient, the pressure is transmitted to the support arm 551 through the support bottom plate 53, the support arm 551 slides downward along the support sleeve plate 552, driving the contact head 554 at the bottom to press the pressure sensor 555, the pressure sensor 555 converts the pressure signal into an electrical signal and transmits it to the controller 7, and the support spring 553 is compressed when the support arm 551 moves downward, forming a buffer, when the pressure decreases, the support spring 553 rebounds to push the support arm 551 to move upward and reset, the pressure of the contact head 554 on the pressure sensor 555 decreases accordingly, and the pressure sensor 555 updates the signal in real time. The way this structure solves the background art problem is that the existing device in the background art lacks a precise pressure transmission and sensing structure, making it difficult to capture the differentiated pressure changes of the two feet, while the monitoring assembly 55 ensures that the pressure corresponding to each placement sleeve plate 52 can be independently and accurately sensed through the guiding cooperation of the support arm 551 and the support sleeve plate 552, the precise contact of the contact head 554 and the pressure sensor 555, and the stable buffering of the support spring 553, avoiding distortion of the pressure signal, laying a foundation for accurate linkage of subsequent protection triggering, and solving the core problem of inaccurate pressure capture of the existing device.

[0035] Further, the protection mechanism 6 comprises a support side plate 61, an air bag storage sleeve plate 62 and a gas injection assembly 63, wherein the support side plate 61 is symmetrically fixedly connected to the support frame 2, the air bag storage sleeve plate 62 is installed on the inner wall of the support side plate 61, and the air bag storage sleeve plate 62 is internally provided with an air bag, The gas injection assembly 63 is installed at the end of the support frame 2, and the gas injection assembly 63 is connected with the air bag storage sleeve plate 62.

[0036] It should be noted that the protection mechanism 6 described in the embodiment can ensure that the two air bags correspond to the two sides of the patient's body by installing the air bag storage sleeve plate 62 through the symmetrically arranged support side plate 61, forming omnidirectional side protection, avoiding no protection coverage when the patient falls to any side, and the built-in storage of the air bag in the air bag storage sleeve plate 62 can prevent the air bag from being damaged by external friction or collision in the non-triggering state, prolonging the service life of the air bag. At the same time, the direct connection of the gas injection assembly 63 and the air bag storage sleeve plate 62 can shorten the gas injection path, ensure the rapid inflation and deployment of the air bag, and avoid protection delay.

[0037] Specifically, when the controller 7 receives the imbalance signal transmitted by the monitoring assembly 55, it immediately sends a start instruction to the gas injection assembly 63, and the gas injection assembly 63 rapidly inflates the air bag in the air bag storage sleeve plate 62 through the connecting channel. The air bag is ejected from the air bag storage sleeve plate 62 and deployed under the action of air pressure, forming a flexible protective barrier on both sides of the patient, blocking the patient from continuing to fall. The way this structure solves the background art problem is that the existing device in the background art has protection trigger delay or false triggering, partly because the installation position of the protection assembly is unreasonable or the inflation path is too long. The protection mechanism 6 fixes the air bag at the key protection position on the side of the patient through the support side plate 61, and cooperates with the short-path gas injection design of the gas injection assembly 63 to ensure that the air bag can be rapidly deployed at the initial stage of the patient's imbalance. At the same time, the protection of the air bag by the air bag storage sleeve plate 62 can avoid false triggering or failure to trigger caused by air bag failure, and cooperate with the accurate signal of the monitoring assembly 55, completely solving the problem of protection trigger delay or false triggering of the existing device.

[0038] Further, the gas injection assembly 63 comprises a fixed side plate 631, a gas pump 632 and a communication pipeline 633, wherein the fixed side plate 631 is fixedly connected to the outer wall end of the support frame 2, the gas pump 632 is installed on the fixed side plate 631, and the air bag storage sleeve plate 62 and the gas pump 632 are provided with the communication pipeline 633 and are connected through the communication pipeline 633.

[0039] It should be noted that the air injection assembly 63 described in this embodiment fixes the air pump 632 at the end of the support frame 2 through the fixing side plate 631, which can provide a stable installation basis for the air pump 632, prevent the air pump 632 from being displaced due to vibration during work, and cause the connecting pipeline 633 to fall off, and the connecting pipeline 633 is directly connected to the air pump 632 and the air bag storage sleeve plate 62, which can reduce the leakage of gas during transmission and ensure that the air pressure generated by the air pump 632 can act on the air bag, thereby improving the air bag deployment speed. At the same time, the shielding protection of the fixing side plate 631 to the air pump 632 can avoid damage to the air pump 632 caused by dust or external force impact.

[0040] Specifically, the working principle of the air injection assembly 63 is as follows: when the controller 7 issues a start instruction, the air pump 632 is powered on and generates high-pressure gas, the high-pressure gas is quickly transported to the air bag in the air bag storage sleeve plate 62 through the connecting pipeline 633, and the air bag breaks through the constraint of the air bag storage sleeve plate 62 and expands under the push of the high-pressure gas. The structure solves the problem of slow inflation of the prior art device in the background art, which is mainly caused by unstable installation of the air pump 632 or gas leakage. The air injection assembly 63 ensures stable operation of the air pump 632 through the fixing side plate 631, and the sealing connection of the connecting pipeline 633 avoids gas leakage, so that the gas generated by the air pump 632 can be efficiently transported to the air bag, greatly shortening the air bag inflation and deployment time, and cooperating with the accurate signal of the monitoring assembly 55, further ensuring the timeliness of the protection trigger, and solving the problem of delayed protection of the prior art device.

[0041] Further, the opening of the installation slot 11 is clamped with an inspection cover plate 12.

[0042] It should be noted that the inspection cover plate 12 at the opening of the installation slot 11 described in this embodiment can isolate the assembly bottom plate 54 and the monitoring assembly 55 inside the installation slot 11 from the external environment, prevent dust, water stains or sundries from entering the installation slot 11 and adhering to the surface of the monitoring assembly 55, affect the sensing accuracy of the pressure sensor 555, and at the same time, the clamping design of the inspection cover plate 12 can be quickly disassembled without the aid of tools, which facilitates the staff to regularly open the installation slot 11 to overhaul, calibrate or replace the monitoring assembly 55, reduces the maintenance difficulty, and ensures the long-term stable operation of the device.

[0043] Further, the top of the support plate 1 is provided with a controller 7, and the pressure sensor 555 and the air pump 632 are electrically connected to the controller 7, and the controller 7 is electrically connected to an external power supply.

[0044] It should be noted that the electrical connection of the controller 7 with the pressure sensor 555, the air pump 632 in the embodiment described in the background enables real-time transmission of signals and rapid issuance of instructions, avoiding the delay of signal transmission leading to lag in protection, and the connection of the controller 7 with the external power supply can ensure that the device continuously obtains stable power supply, preventing monitoring interruption or protection failure due to power failure. At the same time, the controller 7 is installed on the top of the support plate 1, which is convenient for the staff to set parameters or view test data, and improves the convenience of the device.

[0045] Specifically, the external power supply supplies power to the controller 7, the controller 7 receives the pressure electrical signal transmitted by the pressure sensor 555 in real time, analyzes whether the pressure change exceeds the balance threshold through the built-in algorithm, if not, continuously records the pressure data for balance evaluation, if yes, immediately sends the power-on instruction to the air pump 632 to control the air pump 632 to start air injection. The way this structure solves the problem in the background is that the existing device in the background has poor linkage between pressure sensing and protection triggering, and the core reason is the lack of efficient signal processing and instruction issuing unit. As the core control unit, the controller 7 realizes the integrated process of "pressure signal receiving-real-time analysis-triggering instruction sending", shortens the signal processing time, ensures the efficient linkage of the pressure sensor 555 and the air pump 632, and solves the problem of delay or false triggering of the existing device protection triggering from the control level.

[0046] Further, the bottom of the air bag storage sleeve plate 62 is provided with an exhaust hole, and an electromagnetic exhaust valve is installed in the exhaust hole. The electromagnetic exhaust valve is electrically connected with the controller 7, and the inner wall of the air bag storage sleeve plate 62 is pasted with a flexible buffer pad.

[0047] It should be noted that the electromagnetic exhaust valve at the bottom of the air bag storage sleeve plate 62 described in the embodiment can automatically exhaust under the control of the controller 7 after the protection is completed, so that the air bag is quickly deflated and collected into the air bag storage sleeve plate 62, without the need for manual operation, thereby improving the reuse efficiency of the device. The flexible buffer pad on the inner wall of the air bag storage sleeve plate 62 can reduce the friction and collision between the air bag and the inner wall of the sleeve plate when the air bag is inflated and popped out, thereby avoiding damage to the air bag. At the same time, the flexible buffer pad provides secondary buffering when the air bag contacts the patient, preventing the impact force when the air bag is deployed from causing discomfort or harm to the patient.

[0048] Further, the edges of the support frame 2 are arc-shaped structures.

[0049] It should be noted that the arc-shaped structure of the edges of the support frame 2 described in the embodiment can eliminate the sharp corners of the edges of the support frame 2, thereby avoiding the patient from being injured or knocked by the edges of the support frame 2 during the test process due to unstable standing or movement, especially in line with the characteristics of stroke patients who have poor movement coordination and weak self-protection ability, thereby improving the overall safety of the device from the details. At the same time, the arc-shaped structure also makes the appearance of the support frame 2 more rounded, reducing the psychological tension of the patient when using the device.

[0050] In summary, the patient can first sit on the seat 3 on one side of the top of the support plate 1 for pre-test preparation or rest, reducing the movement burden caused by difficulty in movement. When standing for testing, the patient can place both feet on the two symmetrical placement sleeves 52 placed on the top of the support platform 51, and adjust the position of the placement sleeves 52 according to the distance between the two feet to ensure stable standing. The pressure borne by the placement sleeves 52 and the changes in the center of gravity of the patient's body weight is transmitted to the monitoring assembly 55 on the top of the assembly bottom plate 54 in the mounting groove 11 on the side wall of the support plate 1 through the support bottom plate 53 fixedly connected at the bottom. The support arm 551 in the monitoring assembly 55 slides downward along the support sleeve 552 with the pressure, driving the bottom abutting head 554 to extrude the pressure sensor 555 on the top of the lifting head 556, and the support spring 553 is compressed synchronously to form a buffer. The pressure sensor 555 converts the pressure signal into an electrical signal and transmits it to the controller 7 on the top of the support plate 1. The external power supply continuously supplies power to the controller 7. During normal testing, the controller 7 analyzes the pressure signal through the built-in algorithm to evaluate the patient's balance ability. When the patient's body tilts and causes a significant difference in pressure on the two placement sleeves 52, i.e., balance disorder, the controller 7 immediately sends a start command to the air pump 632 of the inflation assembly 63. The air pump 632 is stably installed at the end of the support frame 2 through the fixed side plate 631, and the high-pressure gas generated is quickly delivered to the air bag in the air bag receiving sleeve 62 in the inner wall of the support side plate 61 in the protection mechanism 6 through the communication pipeline 633. The air bag is ejected and expanded under the action of air pressure to form a lateral flexible protection barrier, avoiding the patient from falling. After the test is completed or the protection is completed, the controller 7 controls the electromagnetic exhaust valve in the bottom exhaust hole of the air bag receiving sleeve 62 to open. After the air bag is deflated, it is retrieved into the air bag receiving sleeve 62. The flexible buffer pad on the inner wall of the air bag receiving sleeve 62 can reduce the friction and impact force when the air bag is ejected. The maintenance cover plate 12 at the opening of the mounting groove 11 can isolate external dust and debris, protecting the internal monitoring assembly 55 and the assembly bottom plate 54. The arc-shaped structure at the edge of the support frame 2 can avoid injury caused by collision of the patient, and at the same time, the support frame 2 provides stable support for the protection mechanism 6, ensuring the accuracy of the protection action.
