Description

Technical Field

[0001] This utility model relates to the field of rehabilitation robots, specifically to an integrated testing platform for pneumatic soft rehabilitation gloves. Background Technology

[0002] Stroke, also known as cerebrovascular accident, often results in motor dysfunction such as hemiplegia. Traditional rehabilitation treatment relies on manual assistance from physical therapists, but this has limitations such as high labor costs and insufficient training intensity. To address these issues, pneumatic soft rehabilitation gloves have been introduced into clinical practice. By guiding patients to perform repetitive movement training of the hands or lower limbs, they promote the recovery of nerve, joint, and muscle function. Among existing rehabilitation robots, pneumatic soft rehabilitation robots are gradually becoming a research hotspot due to their advantages such as lightweight and flexibility.

[0003] Like all industrial products, pneumatic soft rehabilitation gloves undergo performance testing before leaving the factory. This testing focuses on two main aspects: (1) checking whether the glove's curvature meets set values ​​under specific positive or negative pressure; and (2) alternating inflation and deflation of the glove to observe its lifespan. Currently, both tests require manual operation, which is inefficient and yields inaccurate results. Therefore, a testing tool suitable for pneumatic soft rehabilitation gloves is needed in this field. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated testing platform for pneumatic soft rehabilitation gloves.

[0005] To achieve the purpose of this utility model, this application provides the following technical solution.

[0006] In a first aspect, this application provides an integrated testing platform for a pneumatic soft rehabilitation glove. The testing platform includes a base, an air pump mounted on the base, a solenoid valve assembly, a control unit, and a connection unit. The connection unit includes an air path connection unit and a signal connection unit. One end of the air path connection unit is connected to the solenoid valve assembly, and the other end is connected to the air passage of the pneumatic soft rehabilitation glove under test. One end of the signal connection unit is equipped with an attitude sensor, which is attached to the pneumatic soft rehabilitation glove under test, and the other end is connected to the control unit. The air pump and solenoid valve assembly are connected to the control unit and their operation is controlled by the control unit.

[0007] This application fully simulates a pneumatic soft rehabilitation glove drive device, which applies a certain positive and negative pressure to the rehabilitation glove through an air pump and solenoid valve assembly. The bending angle of the rehabilitation glove under certain positive and negative pressure conditions is detected (by a posture sensor). This can detect whether the relationship between the bending angle and the pressure meets the set value, and also show whether the rehabilitation glove can maintain the set bending angle after N cycles of alternating positive and negative pressure. Thus, it can be inferred whether the service life of the rehabilitation glove meets the standard.

[0008] In one embodiment of the first aspect, the solenoid valve assembly includes a valve seat and a plurality of first solenoid valves and second solenoid valves mounted on the valve seat. The valve seat is provided with a first air passage and a second air passage, and the valve seat is provided with a plurality of first air outlets. Each first air outlet is connected to the first air passage through a first gas channel, and a first solenoid valve is disposed in the first gas channel. Each first air outlet is connected to the second air passage through a second gas channel, and a second solenoid valve is disposed in the second gas channel.

[0009] In one embodiment of the first aspect, the air pump includes a first air pump and a second air pump, wherein the first air pump is a positive pressure pump and the second air pump is a negative pressure pump. One end of the first air passage is closed, and the other end is connected to the first air pump; one end of the second air passage is closed, and the other end is connected to the second air pump. Through the above-described air path arrangement, positive pressure drive and negative pressure drive can be switched between each other without affecting each other.

[0010] In one embodiment of the first aspect, the testing platform is equipped with a noise-silencing filter unit. One air port of the first and second air pumps is connected to the noise-silencing filter unit and then to the atmosphere. The noise-silencing filter unit is provided to reduce the noise generated by the first and second air pumps when drawing or expelling air into or from the atmosphere, and to filter the air, preventing dust from entering the rehabilitation gloves and damaging their air passages, reducing their lifespan, and thus affecting the accuracy of the test results. In this application, the noise-silencing filter unit comprises three parts: a Y-type reducing valve, a silencer, and a filter, wherein the two outlets of the Y-type reducing valve are respectively connected to the first and second air pumps.

[0011] In one embodiment of the first aspect, the valve seat has a plurality of second air outlets, each second air outlet corresponding to a first air outlet, and both connected to a first solenoid valve and a second solenoid valve. The second air outlet is provided with a pressure sensor, which is connected to a control unit.

[0012] In one embodiment of the first aspect, the base is provided with a socket, which includes an endotracheal connector and a signal connector. The endotracheal connector communicates with a first air outlet, and the signal connector is connected to a control unit. One end of the airway connection unit is provided with a plug, which includes an endotracheal connector and a signal connector. The endotracheal connector matches the endotracheal connector, and the signal connector matches the signal connector. This configuration is mainly for ease of assembly and disassembly. When one rehabilitation glove is being tested, the connection unit can be installed on another rehabilitation glove to be tested, including attaching a posture sensor to the surface of the rehabilitation glove and then connecting an endotracheal tube to the airway of the rehabilitation glove to be tested. Both the endotracheal tube and the posture sensor are connected to the plug. For testing, simply plugging the plug into the socket enables airway and signal connectivity, making it faster and more convenient.

[0013] In one embodiment of the first aspect, the control unit includes a PLC controller and a data logger. The PLC controller controls the operation of the first air pump, the second air pump, and the solenoid valve assembly; the data logger records data from a pressure sensor and a posture sensor, and compares the relationship between air pressure and bending angle in real time to determine whether the rehabilitation glove under test is operating normally.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By automatically controlling the operation of the air pump and solenoid valve group through the control unit, and automatically completing the collection of test data, the testing of pneumatic soft rehabilitation gloves is more automated and more accurate. Attached Figure Description

However, the protection scope of this utility model is not limited to the following embodiments. Example

[0023] An integrated testing platform for pneumatic soft rehabilitation gloves, the structure of which is as follows: Figure 1 As shown, the device includes a base 1, a solenoid valve seat 7 fixed on the base 1, a first air pump 2, a second air pump 3, a silencer filter unit 6, a PLC controller 5, a data acquisition instrument 4, and a series of connectors. The first air pump 2 is a positive pressure pump, drawing air from the atmosphere and injecting it into the rehabilitation glove 10 to be tested; the second air pump 3 is a negative pressure pump, drawing gas from the rehabilitation glove 10 and releasing it into the atmosphere. A solenoid valve assembly 8 is installed on the solenoid valve seat 7. This assembly contains 10 solenoid valves, arranged in pairs of two. Each pair of solenoid valves includes a first solenoid valve 13 and a second solenoid valve 14. Details are as follows:

[0024] The solenoid valve seat 7 has a first air passage 11 and a second air passage 12, one end of which is closed and the other end is open. The open end of the first air passage 11 is connected to the air outlet of the first air pump 2, and the open end of the second air passage 12 is connected to the air inlet of the second air pump 3. The air inlet of the first air pump 2 and the air outlet of the second air pump 3 are connected to the silencer filter unit 6 and are open to the atmosphere. The solenoid valve seat 7 has five first air outlets 17 and five second air outlets 18. Each first air outlet 17 is connected to the air passage of the rehabilitation glove 10 to be tested through a pipeline; each second air outlet 18 is equipped with a pressure sensor 19. Each first air outlet 17 and a corresponding second air outlet 18 are connected to the first air passage 11 through a first gas channel 15, and a first solenoid valve 13 is installed on the first gas channel 15. At the same time, each first air outlet 17 and a corresponding second air outlet 18 are connected to the second air passage 12 through a second gas channel 16, and a second solenoid valve 14 is installed on the second gas channel 16. Specifically, such as Figure 2 As shown.

[0025] Before testing, take a connection unit, such as... Figure 3 As shown, the connection unit includes a plug 9 and a connecting cable 20. Inside the connecting cable 20 are five data cables and five air tubes. The five air tubes are respectively connected to five airways of the rehabilitation glove 10 under test. One end of each of the five data cables is equipped with a posture sensor 21, which is either attached to the surface of the rehabilitation glove 10 or inserted into the cavity wall of the glove 10. The plug 9 is then inserted into the socket on the base 1 to complete the installation.

[0026] The PLC controller 5 is connected to the first air pump 2, the second air pump 3, and 10 solenoid valves to control the operation of the above components; the data acquisition instrument 4 is connected to the air pressure sensor 19 and the attitude sensor 21 to collect air pressure data and bending angle data.

[0027] The working process of the above testing platform is as follows:

[0028] (1) Connect the connection unit to the rehabilitation glove 10 to be tested, and then insert the plug 9 into the socket on the base 1.

[0029] (2) The PLC controller 5 controls the operation of the first air pump 2, opens the first solenoid valve 13, and closes the second solenoid valve 14 and the second air pump 3. At this time, the gas passes sequentially through the silencer filter unit 6, the first air pump 2, the first air passage 11, the first air outlet 17, the plug 9, and the air tube, and then enters the rehabilitation glove 10 under test. The air pressure inside the rehabilitation glove 10 increases (positive pressure) and gradually bends. At this time, the air pressure sensor 19 detects the air pressure at the second air outlet 18, but since the air passage is connected, this air pressure value is the air pressure value inside the rehabilitation glove 10 under test. The posture sensor 21 detects the bending angle of the rehabilitation glove 10 under test. The data acquisition instrument 4 records in real time.

[0030] (3) After 5-10 seconds, the PLC controller 5 controls the second air pump 3 to run, the second solenoid valve 14 opens, and the first solenoid valve 13 and the first air pump 2 close. At this time, the gas passes sequentially through the rehabilitation glove 10 under test, the air tube, the plug 9, the first air outlet 17, the second airway 12, the second air pump 3, and the silencer filter unit 6, and then is discharged into the atmosphere. At this time, the air pressure inside the rehabilitation glove 10 under test gradually decreases until it becomes negative pressure, and the rehabilitation glove 10 under test gradually straightens from a bent position, and then bends in the opposite direction. Similarly, the air pressure sensor 19 detects the air pressure value inside the rehabilitation glove 10 under test. The posture sensor 21 detects the bending angle of the rehabilitation glove 10 under test. The data acquisition instrument 4 records in real time.

[0031] (4) Repeat steps (2) and (3), and the rehabilitation glove 10 to be tested will switch between forward bending and reverse bending continuously. After N cycles of alternating positive and negative pressure, whether the rehabilitation glove 10 to be tested can still maintain the set bending angle under a certain air pressure can be used to infer whether the service life of the rehabilitation glove meets the standard.

[0032] The above description of the embodiments is intended to enable those skilled in the art to understand and apply this application. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, this application is not limited to the embodiments described herein, and any improvements and modifications made by those skilled in the art based on the disclosure of this application without departing from the scope and spirit of this application are within the scope of this application.
