TECHNICAL FIELD

[0001] The present application relates to the technical field of hand rehabilitation training, in particular to a hand rehabilitation training system. BACKGROUND

[0002] The hand is a very complex motor organ of human beings, which has the characteristics of delicate structure and flexible movement, and its function involves touch and movement integration, and can complete important movements such as grabbing, holding and pinching in daily life.

[0003] Once the finger movement function is lost, it will bring inconvenience to the patient, and the rehabilitation of hand dysfunction is a difficult problem universally faced in the world at present. The traditional finger rehabilitation treatment method is that the physician long-term pulls the patient's fingers to do rehabilitation movement, but the number of rehabilitation physicians is relatively short compared with the number of patients. The hand rehabilitation training device alleviates the shortage of rehabilitation physicians to a certain extent.

[0004] Most of the current hand rehabilitation training devices and systems use sensors to collect the bending information of the user's fingers, model or match the pressure data in different data statistical software systems, so that doctors and users can intuitively understand the change of the hand damage and the intensity of the rehabilitation training over time, thereby obtaining the data effect. The data of the rehabilitation training is quantified to provide a theoretical basis for the treatment of physicians.

[0005] Such similar hand training devices can only train or detect the strength data of the hand, that is, a training device and an independent hand function evaluation device are needed, and the adjustment of the training device also needs to rely on the data of the evaluation device for guidance. The operation is complicated, and the rehabilitation training device generally generates impedance through the elastic force of the whole palm to adjust the bending intensity, which has low adjustment precision, and the adjustment of the palm is integral, which does not match the actual situation of the patient's recovery.

[0006] Based on this, the present application designs a hand rehabilitation training system to solve the above problems. SUMMARY

[0037] Please refer to Figs. 1 to 4 The present application provides a hand rehabilitation training system, in order to better understand the above technical solutions, the following will be combined with the description of the drawings and the specific embodiments of the above technical solutions are described in detail.

[0038] In one specific embodiment of the technical solutions of the present application:

[0039] It comprises training gloves 1, computer 11, pressure guide pipe 2 and positioning box 3;

[0040] The training gloves 1 are closed gloves; 5 pressure guide pipes 2 are arranged on the training gloves 1, and the pressure guide pipes 2 are open-ended silicone hoses; the 5 pressure guide pipes 2 are arranged along the extension directions of the different five fingers;

[0041] The front end of the pressure guide pipe 2 is fixed on a positioning frame 22, and the front end of the pressure guide pipe 2 is sealingly connected with the telescopic pipe 21, and the joint needs to be clamped stably.

[0042] A positioning frame 22 is arranged between each finger joint of the training gloves 1, and a telescopic pipe 21 is arranged between every two adjacent positioning frames 22, the adjacent telescopic pipes 21 on the same finger are sealingly connected, and the rear ends of the mutually communicating telescopic pipes 21 are sealingly connected with a pressure guide pipe 2; the telescopic pipe 21 can be a corrugated pipe or a pipe that can only stretch but cannot bend radially, which can ensure the conduction and communication of the internal pressure of the pressure guide pipe 22 and avoid the deformation of the telescopic pipe 21 in other directions, resulting in pressure failure, so that the impedance can train the fingers, and therefore a plurality of limiting blocks 23 are arranged on the left and right sides of the telescopic pipe 21 to limit the movement of the telescopic pipe 21; the telescopic pipe 21 is a silicone high-pressure hose, and a positioning frame 22 is arranged at both ends of the telescopic pipe 21, and the both ends of the telescopic pipe 21 are fixedly connected with the positioning frames 22, and the telescopic pipe 21 covers the outside of the finger joints. Ensure that the bending and opening of each telescopic pipe 21 are matched with a finger for individual matching, and ensure that different telescopic pipes 21 do not affect each other.

[0043] The rear end of the training glove 1 is also provided with a positioning box 3, and the positioning box 3 is internally provided with five air valves 31. Each air valve 31 is provided with a pressure sensor 33 at the top, and the front end of each air valve 31 is in sealed communication with the rear end of a pressure guide pipe 2. The front end of the air valve 31 is provided with a temperature sensor 32. The temperature sensor 32 is sleeved outside the rear end of the pressure guide pipe 2.

[0044] Each air valve 31, temperature sensor 32 and pressure sensor 33 are connected with a computer 11.

[0045] The training intensity adjusting method comprises the following steps:

[0046] Step S1, the training personnel wear the training glove 1, and the five fingers are matched with the glove one by one.

[0047] Step S2, the fingers are bent, the stretchable tube 21 is elongated by the bent fingers, the air pressure in the pressure guide pipe 2 becomes smaller, the pressure becomes smaller, the stretchable tube 21 remains in the state of retraction and shortening under the condition of smaller pressure, the impedance of the stretchable tube 21 is generated to the fingers through the retraction intensity, and the fingers are resisted from bending. Conversely, the fingers are opened, the stretchable tube 21 is shortened by the fingers, the gas in the stretchable tube 21 is compressed, the air pressure in the pressure guide pipe 2 becomes larger, the pressure in the stretchable tube 21 increases to generate impedance, and the fingers are resisted from opening, so as to achieve the training purpose.

[0048] The pressure sensor 33 detects the air pressure value in the corresponding pressure guide pipe 2;

[0049] The temperature sensor 32 detects the temperature change of the corresponding pressure guide pipe 2, and records the temperature value and the air pressure value through the computer 11;

[0050] Step S3, the pressure value in each pressure guide pipe 2 is calculated through the temperature value and the air pressure value;

[0051] Step S4, the impedance of the training personnel is judged through the pressure value, the stretchable tube 21 is compressed or elongated, the pressure of the pressure guide pipe 2 changes, the finger movement is hindered, and the active impedance of the finger rehabilitation training is generated.

[0052] Further comprising step S5, the gas is pumped into or pumped out of the air valve 31 through the air pump, the internal pressure of the pressure guide pipe 2 and the connected stretchable tube 21 is adjusted, the impedance size is changed, and the training pressure size suitable for the patient is matched. The pressure guide pipe 2 and the connected stretchable tube 21 above each finger are communicated as a complete closed pipeline, the training pressure of different fingers can be adjusted individually through the air pump and the air valve 31, so as to achieve the purpose that different fingers have different training impedance sizes.

[0053] It should be noted that:

[0054] 1. Current devices of this type detect the force of springs. However, springs have inherent elasticity, and the force of springs is uncontrollable. Springs have low elasticity at the beginning of compression and high compression at the end, resulting in uneven impedance. The spring's stroke and compression force are undetectable in this type of rehabilitation training and can only be calculated based on the spring force itself. This device quantifies the impedance through the pressure guide tube 2 and forms precise impedance for finger flexion and extension through the telescopic tube 21. It also standardizes the values ​​to ensure the consistency of impedance and achieve the purpose of standardized training, rather than having low impedance at the beginning of the stroke and high impedance at the end. This system ensures impedance consistency and makes the training more standardized.

[0055] 2. Current rehabilitation training devices and systems generally train on a per-palm basis, with uniform adjustment of the force on a single palm. This device, however, precisely adjusts the force on each finger. Each finger is adjusted via pressure guide tube 2 and air valve 31 to adapt to different training resistances of different fingers, achieving precise and quantitative training.

[0056] 3. The existing system is heavy, and the quantification of resistance training is detected and adjusted by force, which is difficult to adjust and requires replacing the spring or the device that generates resistance. It is also difficult to roughly judge the work done in hand training, and can only judge how many sets of flexion and extension movements were performed. This device adds a temperature sensor 32, which detects the temperature of the gas in the pressure tube 2 and detects the temperature difference generated during other compressions. Moreover, it can detect each set of finger flexion and extension movements, and obtain the accurate temperature change of the total activity, thereby obtaining the approximate total work done, which can determine the approximate amount of exercise in rehabilitation training.

[0057] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
