Preferably, the actuating assembly is configured to drive the accommodating area to move in a manner of changing an included angle of a reference surface of the accommodating area relative to a plane surface by acting on a back surface of the accommodating area, wherein the reference surface is a surface capable of representing an opening surface of the accommodating area. For example, if the receiving area is configured substantially as a hemispherical concave surface or a concave surface, the reference surface may be a surface flush with the opening, and a plane surface may be understood as a horizontal surface, which may also be manually confirmed to be changed in some non-ground-referenced treatment situations.

According to a preferred embodiment, the second actuating assembly is constituted by a plurality of second actuating units, at least one portion of each second actuating unit being in contact with the second housing zone. Similarly, the second robot assembly also comprises a plurality of second actuating units, and at least one part of each second actuating unit is contacted with the second accommodating area. Preferably, in the lead interval, the pressure of the physiological part of the patient corresponding to the accommodating area contacted by all the second actuating units against the position is retrieved, and one or more second actuating units corresponding to the maximum resisting pressure are detected.

Further, in the rear section, a second included angle between the reference plane and the level plane generated by the detected one or more second actuating units at the correspondingly contacted second accommodating area part is increased according to a preset increment mode. The reference plane is a plane on which the contact surface of the robot cell is located, and if the contact is curved, a tangent plane of a substantially vertex may be used as the reference plane. The front interval and the rear interval are time periods which can be set manually, and the sequence of the process time of searching and angle adjusting is mainly divided. The second angle may be understood as a dihedral angle, which may range from 0 to 180 °, but is generally not more than 90 ° at the maximum, in view of the restricted relationship of the receiving area to the physiological site of the patient.

According to a preferred embodiment, the predetermined increment is limited to within a difference between a preset maximum limit and a preset minimum limit of the second angle, and preferably the predetermined increment is less than half of the difference, so that the controlled variable second angle is increased in a manner of half-grid change at most, and the design is to prevent the single angle change from being too large to cause excessive stimulation effect on part of the patients, because part of the patients using the device are mental disorder patients or suffer from certain restless symptoms, and the accommodation area is to limit the limbs of the part of the patients, however, if the single adjustment angle is too large to cause the stimulation of the patients by actions beyond a range which can be ignored, the stimulation of the patients can cause strong reaction of the patients, so that the patients are more nervous and dangerous.

In particular, based on the above half-grid variation manner, increasing the partially selected second included angle to the preset maximum in a "relatively slow" manner at least twice or even more than three times will significantly reduce the stress response of the patient, and can stabilize the mood of the patient. And the scheme only adjusts the second included angle of the part when the part with the maximum resistance pressure is detected, on one hand, free movement space is given to the rest parts of the patients, so that the rest parts are not or not mainly influenced by the limiting action, and meanwhile, certain intervention can be performed on the parts (embodied as the parts with the maximum resistance pressure) to be struggled or struggled by the patients.

Therefore, the scheme selects the mode of changing the angle to change the support angle of the force applied by the limb of the patient, when the patient applies force by using a certain fulcrum and intends to break loose, the scheme can accurately detect the force application fulcrum and change the fulcrum or the support angle of the force applied by the patient by using the angle change with low irritation at least at two ends, so that the patient can not act by using the previous force application mode, and the patient can give up or cannot break loose the constraint in a relatively non-antagonistic mode. Additionally, the alternating operation of the actuating assemblies or actuating units in the scheme can enable each part of the limb of the patient to obtain sufficient pressure change massage effect, and has significant advantages for preventing pressure sores and limb hematoma and edema.

According to a preferred embodiment, after the second actuation unit has controlled the second angle to increase to the preset maximum, it is possible to restore to the preset minimum or to the angle of the counter pressure with the limb of the patient.

According to a preferred embodiment, after a part of the second actuating units controls the second angle to increase to the preset maximum limit, the counter pressure of the part of the second actuating units continues to increase, or when a preset number of second actuating units are exceeded to control the second angle to increase to the preset maximum limit, the first actuating units of the first actuating assemblies are controlled to control the first accommodating zones in such a way as to reduce the preset first angle decrement, and in the process, the second actuating units are controlled to operate in such a way as to reduce the second angle by an amount between the preset maximum limit and the minimum limit of the second angle, preferably within a half-grid change.

Above-mentioned scheme, when injecing patient's limbs, especially injecing the limbs struggle like the hand, the patient still struggles when the restriction is the biggest, then through the mode that changes its arm, adjust the contained angle relation of its application of force point and hand to make the patient need the gravity that bigger power just can oppose its self arm, and contained angle application of force point and contained angle that change make the patient on the one hand comparatively difficult to the application of force at the application of force point, on the other hand the increase of this contained angle makes the restraint that the patient received stimulate littleer, is showing to alleviate its stress response. Thereby the effect of non-antagonism formula restraint has been realized to this scheme, can show the restless psychology that reduces the patient, effectively retrains patient's limbs, prevents pressing sore, preventing the edema, accelerateing recovered possesses apparent advantage to it.
