Description

Finger grip rehabilitation training device

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a finger grip strength rehabilitation training device.

Background

Rheumatoid arthritis requires not only medical treatment but also appropriate rehabilitation training, and among them, rehabilitation with finger function is the most difficult. Except that rheumatoid arthritis patients need finger function rehabilitation training, in life, both hands are often in a frequent motion state, and when danger is met, both hands can naturally protect the body and are easily damaged, and the disability rate after the hands are injured is high, so that the life quality of the patients is seriously influenced. Therefore, rehabilitation training of finger function is necessary. At present, the finger rehabilitation training equipment on the market mainly utilizes surface electromyogram signal triggering and dynamic intelligent control to complete interactive biofeedback training so as to realize the finger function rehabilitation training of a patient, however, the mechanism is complex, the price is high, a fine adjustment mechanism is lacked, and the cost pressure of rehabilitation treatment is large for common patients. In addition, finger function rehabilitation training is performed by extracting a heavy object, but the simple mode cannot detect the gripping strength of the fingers of the patient, the gripping strength is one of important indexes in the finger function rehabilitation training, the strength does not reach the standard in the finger function rehabilitation training, and the rehabilitation treatment effect is greatly reduced. Meanwhile, in the process of rehabilitation training of a patient, the finger strength training and the wrist strength training are different, and the existing training equipment is difficult to distinguish the finger strength training and the wrist strength training, so that the rehabilitation training equipment which is low in cost and can judge whether the finger grip strength reaches the standard and whether the strength exerting part is correct is needed.

Disclosure of Invention

The invention aims to provide a finger grip strength rehabilitation training device to solve the problems that the existing finger rehabilitation equipment is high in cost and cannot judge whether the finger grip strength reaches the standard or not and whether the force application part is correct or not.

In order to achieve the purpose, the basic scheme of the invention provides a finger grip strength rehabilitation training device which comprises a training seat, wherein a vertical plate and a detection part are fixedly connected to the training seat, a plurality of force meters are fixedly connected to the vertical plate, a first spring is fixedly connected to the force measuring end of each force meter, and a finger sleeve is fixedly connected to the first spring; the detection part comprises a detection box and a first alarm, a plurality of sliding plates are vertically and slidably connected in the detection box, each sliding plate is fixedly connected with a plurality of second springs and supporting rods, one ends of the second springs, far away from the sliding plates, are fixedly connected with the bottom wall of the detection box, and the bottom ends of the supporting rods are suspended in the air; fixedly connected with feeler lever on the sliding plate that is close to the riser, the bottom fixedly connected with conducting block of feeler lever sets up on the diapire of detection case and supplies the complete male jack of conducting block, two first polar plates of fixedly connected with on the diapire of detection case, can contact with two first polar plates when conducting block removes, and first polar plate line connection has the switch, and another first polar plate and first alarm line connection, switch and first alarm line connection.

The principle and the beneficial effect of the basic scheme are as follows: in this scheme, the patient places the hand naturally on the sliding plate of detection portion, and the sliding plate slides to detection case diapire direction under the action of gravity, and conducting block on the feeler lever contacts through two first polar plates with it, but the switch is in normally open state this moment, and consequently first alarm does not send out the police dispatch newspaper. When the patient carries out finger grip training, whether the dynamics of finger grip reaches standard is judged through observing the numerical value that the ergograph shows. Meanwhile, in the training process, if the patient does not apply force by using the finger part, but applies force by using the wrist part, the front end (the part close to the finger) of the palm is lifted upwards, at the moment, the sliding plate slides upwards under the action of the second spring, the contact rod and the conducting block move upwards, the conducting block is contacted with the two first polar plates, at the moment, the switch is in a closed state, the first alarm is electrified to give an alarm, and the situation that the force application part for the training is unqualified is indicated, and the training needs to be carried out again. Therefore, compare in the training equipment on the market, the trainer in this scheme not only cost is comparatively cheap, and the ordinary patient homoenergetic can bear the expense of rehabilitation to, can also judge whether the position of exerting oneself of patient when carrying out rehabilitation is correct, ensure the effect of rehabilitation.

The training ware in this scheme not only can point the rehabilitation training, can also carry out the rehabilitation training of wrist portion, only needs at the training in-process for the switch all the time be in normally open state can, first alarm can not send out the police dispatch newspaper, and the patient wears the finger cover on the finger, rotates the wrist portion and can carry out the rehabilitation training of wrist portion, provides multiple rehabilitation training selection for the patient.

Design a plurality of tensiometers and dactylotheca in this scheme, the patient can carry out the rehabilitation training of single finger, also can carry out the rehabilitation training of many fingers simultaneously, and the patient can freely select the rehabilitation training scheme according to the doctor's advice.

Further, still include the second detection portion, the second detection portion includes the movable block, and the movable block articulates there is wobbling driving lever, and the one end that the movable block was kept away from to the driving lever is close to and is equipped with the button, and the button is connected with the second alarm, and the mid point of driving lever articulates there is the support, and the driving lever rotates around the support level. The scheme can detect backward movement of the arm, when the arm moves backward, the movable block can be pushed to move, the movable block drives one end of the shifting rod to move backward, the other end of the shifting rod moves forward, and therefore the button is pressed, the second alarm is triggered to give an alarm, and the fact that the exercise cannot be counted is indicated.

Furthermore, the button is fixedly connected with a trigger block which can conduct electricity, the trigger block can be contacted with the two second pole plates when moving, the second pole plate is connected with a second alarm through a circuit, and the other second pole plate is connected with a second alarm through a circuit. The trigger block in the button contacts with the second pole plate in the moving process, so that the pole plate, the trigger block and the second alarm are communicated to form a closed loop, and the second alarm gives an alarm.

Further, the horizontal sliding connection of movable block is on training the seat, and fixedly connected with fixed plate on the training seat has set up threaded hole on the fixed plate, and threaded hole threaded connection has the screw thread post. The movable block can move on the training seat, and the motion trail of the movable block is ensured.

Further, the lateral wall of movable block still is equipped with the standing groove of placing the arm, and standing groove sliding connection is on the training seat. Therefore, the placing position of the arm can be restrained, the swinging of the arm can be placed, and the arm can only move back and forth, so that the detection accuracy of the backward movement action is improved.
