As shown in fig. 3 and 4, the active and passive exercise rehabilitation training device for hands of the utility model can perform active training and passive training in the using process.
The active training mode comprises an active resistance mode and an active power-assisted training mode.
The active resistance mode refers to a mode in which a patient exerts force to resist the shape of the rehabilitation training instrument, and is divided into active resistance stretching training and active resistance grasping training. In the active resistance mode, positive pressure and negative pressure are applied to the soft actuating actuator of the finger training part by adjusting the air pump. Different gears correspond to preset pressurizing degrees with different strengths, and the different preset pressurizing degrees are realized by the amount of inflation. For example, the gear 1 represents the strength 1, the gear 2 represents the strength 2, the gear 3 represents the strength 3, the strength 1 is the smallest, the strength 2 is the middle, and the strength 3 is the largest. In the gear 1, when a patient exerts force by himself, the resistance of fingers is small, the patient can easily resist the resistance of the actuator, and hand stretching and bending are completed; in the gear 3, the resistance of the fingers is large, and the patient must use large strength to actuate the actuator against the soft body to complete the extension and the bending of the hand. When actuating the executor to the software and applying the malleation, patient's hand is crooked gradually under this pressure effect, the back is accomplished in the pressurization, patient's hand is the bending of maximum degree under this pressure effect this moment, and then patient self is exerted oneself and is resisted the bending, and maximum strength extends the palm of oneself, has entered the initiative and has resisted the extension training this moment promptly, and baroceptor obtains whether preset training value is hit to user's hand motion state and dynamics through monitoring gas circuit pressure variation, if reach preset training action and dynamics, the suggestion once stretches the training and accomplishes. When the software actuates the executor and applys the negative pressure, the patient palm stretches gradually, and after the pressurization is accomplished, patient's hand presents the state that furthest expanded under the negative pressure effect, then patient self power of exerting oneself crooked palm, resists the hand state of expanding, has entered into the initiative and has resisted the gripping training this moment promptly, and baroceptor obtains whether patient's hand motion state and dynamics reach predetermined training value through monitoring gas circuit pressure change, if reach predetermined training action and dynamics, reminds a gripping training to accomplish. When the negative pressure is applied to the fingers, the pressure can be applied in sequence, for example, the pressure is reduced from the fingertips to the tail ends of the fingers, and the negative pressure traction force is stronger at the moment, so that the spasm masses can be pulled away and the hand can be contracted or the spasm can be prevented.
The active power-assisted training mode is that the system obtains a hand muscle force diagram of a user through myoelectricity acquisition electrode analysis, acts on the software actuation actuator, and the system is inflated or deflated according to the will of a patient to assist the patient in realizing hand grasping and hand stretching motions. The training mode needs to be realized by an external control system, and the specific implementation mode is as follows: under the active power-assisted mode, the hands of the patient autonomously move, the controller host system analyzes through the myoelectricity acquisition electrode to obtain a hand muscle diagram of the user, and controls the air pump to apply positive pressure/negative pressure to the soft actuating actuator of the finger training part according to the intention of the muscle diagram corresponding to the hand gripping or stretching movement, so as to assist the patient to complete the hand gripping/stretching action. Specifically, when a patient wants to perform a gripping movement, the system analyzes through the myoelectricity collecting electrode to obtain that the patient has a gripping intention, at the moment, the air pump works to inflate (add positive pressure to) the actuator, and therefore the purpose of assisting the patient to actively finish gripping is achieved; when the hand of the patient tries to realize stretching movement, the system analyzes through the myoelectricity collecting electrode to obtain that the patient has stretching will, the air pump works at the moment, and the actuator is pumped out (negative pressure is added), so that the patient is assisted to actively finish the hand stretching movement. Optionally, by adding sensors and/or accessories such as angle and/or acceleration on the rehabilitation training instrument, the intention and hand movement of the patient can be better monitored and evaluated.
The passive training mode comprises a passive timing training mode and a passive counting training mode. In the passive training mode, the air pump applies corresponding pressure to a software actuating actuator of the finger training part according to a gear set by a user, the finger joint completes the activity training of the finger passive joint under the driving of the software actuating actuator, the air pressure sensor monitors the pressure change of the air path in the process, and prompt and early warning is carried out if an abnormal state exists. Specifically, in a passive timing training mode, a user sets specific time, then the air pump applies positive pressure (inflation) and negative pressure (air exhaust) to the soft actuator, the hand of the user performs corresponding bending motion and stretching motion under the driving of the soft actuator, and the bending and stretching of the hand of the user alternately and repeatedly move until the timing is finished; in the passive counting training mode, the user sets specific times, then the air pump applies positive pressure (inflation) and negative pressure (air exhaust) to the soft actuator, the hand of the user performs corresponding bending movement and stretching movement under the driving of the soft actuator, and the bending and stretching alternate repeated movement of the hand of the user is completed after counting. The passive training mode adopts full automated design, uses manpower sparingly, need not other people and attends always, reduces the labour.
The utility model discloses the active and passive exercise rehabilitation training device of hand is by the host computer that provides the pressure air current and equipped the software and actuate the finger training portion of executor and constitute. The software actuates the executor and takes place crooked deformation under the effect of atmospheric pressure for the tensile dynamics of extension has had the promotion of a great degree, and simultaneously through the pressure size of adjusting air pump output air current, the initiative training mode of increase different intensity satisfies the recovered demand of patient's higher requirement, and the device can carry out an aassessment to patient self state of exerting oneself simultaneously, fine satisfied patient rehabilitation training's demand.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
