Background of the Invention The statement of this section merely provides the background art related to the present disclosure, and does not necessarily constitute the prior art.

Lymphedema refers to a disease that lymphatic return is blocked or reduced in soft tissues.

The lymphedema after breast cancer surgery is generally believed to be caused by the fact that axillary lymph node dissection disrupts the lymphatic pathway of return from the upper limb to the armpit.

Proteins are accumulated in the tissues, so that the osmotic pressure increases to absorb water and cause lymphedema of the affected limb.

The main manifestations are: subcutaneous fiber, fat and tissue hyperplasia, and thickened limb.

If the patient overuses the affected limb after the surgery, the edema will be gradually aggravated.

Even if the edema is eliminated by massage and the application of bagged mirabilite, the edema will become fibrotic to form scar tissues.

Lymphedema on the upper side of the affected limb seriously affects the life quality of the patient.

It not only brings physical pain and movement disorders to the patient, but also brings a huge psychological shadow to the patient.

The inventors found that there are many ways to eliminate the edema of the affected limb, for example, using bagged mirabilite or Chinese medicine to eliminate the edema, but the edema will still recur after the elimination; for example, postoperative rehabilitation motions such as gymnastics to accelerate the blood circulation and eliminate the edema, but it is difficult to control the activity intensity during the rehabilitation motion and the pain of the affected limb is stimulated.

In view of the above problems, the present disclosure puts forward a device for preventing and eliminating edema of an affected limb, an auxiliary motion system and a working method.

LUT01988 When the edema has occurred, the electric heating mechanism wound on the outside of the sleeve can accelerate the blood circulation of the edema-affected limb through hot compresses, thereby increasing the absorption speed of lymph in the affected limb. | At the same time, the sleeve is tightened by the restraint strap to slow down the | diffusion of lymph, thereby achieving the effect of quickly eliminating the edema. | The restraint strap is wound on the outside of the sleeve to form a winding structure. When the other end of the restraint strap is tightened, the sleeve does not rotate. Due to the superimposed force of the winding, the restraint strap produces a surrounding extrusion force on the sleeve. Accordingly, the restraining extrusion force is applied to the affected limb to actively compress the affected limb. By applying pressure to the affected limb, the degree of edema is reduced, thereby increasing the speed of subsequent edema elimination. The bracket includes two fixing rings 201 and a connecting rod, the two fixing rings are respectively fixed to both ends of the sleeve, and the two fixing rings are connected by the connecting rod. The reel coaxially cooperates with the connecting rod, and the length of the restraint strap in the axial direction of the reel is greater than the length of an edema range of the affected limb, such that the function range of the restraint strap covers the edema range.

The power supply is installed on the bracket, and its position is adjusted to no hinder to the movement of the elements and the affected limb.

There are a plurality of mechanical sensors, which are arranged at intervals and distributed on the inner wall of the sleeve; in order to ensure the accuracy of pressure measurement, the mechanical sensors are arranged around the inner wall of the sleeve to obtain pressure conditions of circumferential everywhere; the mechanical sensors and the driving mechanism are respectively connected to the controller, and the controller controls the operation of the driving mechanism according to the obtained pressure change.

It can be understood that the inside of the sleeve is preset with mounting positions, and the mechanical sensors are respectively installed corresponding to the mounting positions on the inside of the sleeve to detect the pressure information of respective force-bearing parts.

The internal pressure conditions of the sleeve are monitored by the mechanical sensors to prejudge the occurrence of edema. Pressure is applied to the sleeve through ee. |

| 10 the restraint strap, thereby pre-compressing the affected limb, reducing the degree of LU101988 edema, and alleviating the diffusion of lymph caused by the increase in osmotic pressure of the affected limb, and shortening the recovery time. The corresponding driving mechanisms are respectively driven to operate according to the pressure values measured by the corresponding mechanical sensors. The two sleeves correspond to a first driving mechanism 3 and a second driving mechanism 7, respectively. The two brackets corresponding to the two sleeves are hinged through an auxiliary bracket 10, an auxiliary driving mechanism 5 is provided at the hinged joint, and the auxiliary driving mechanism drives one bracket to rotate relative to the other bracket around the hinged joint to change the angle between the two brackets for driving the angle between the upper arm and the lower arm. The brackets, the auxiliary bracket and the auxiliary driving mechanism together constitute the auxiliary motion system, the auxiliary driving mechanism is a flat large-torque motor, and the two brackets serve as two transmission arms respectively; the flat large-torque motor is electrically connected to the controller, and the controller controls the operation of the auxiliary driving mechanism according to the data obtained by the mechanical sensors on the two sleeves, thereby increasing or reducing the angle between the two brackets.

When it is detected that the upper limb of the patient needs to exert force, the auxiliary motion system is activated, the flat large-torque motor operates, and the brackets are driven to drive the affected limb to move, so as to help patient’s activities such as lifting a heavy object.

It can assist the patient's affected limb to move while protecting the affected limb; when the patient's affected limb is moving, the muscle tension causes the force measuring units to sense force changes, the restraint straps are tightened, and the auxiliary driving mechanism drives the affected limb to move, so as to assist the patient to implement the operation.

The shoulder fixing sleeve 11, the back patch 12, the upper arm patch 13, and the two force strain gauges 14 form an upper arm monitoring module, which is used to determine whether the upper arm is in a horizontal rotation state or a raised state.

When the forces applied to the two strain gauges are the same, the rotation state can be determined, and the upper arm is not exerting force, so no auxiliary motion is required. When the force applied to the upper strain gauge is small and the force on the lower strain gauge is large, it can be determined as a process of raising the upper arm, and the auxiliary motion system is activated at this time.

At the same time, because the edge of the shoulder fixing sleeve is arc-shaped, the raising angle of the upper arm can be suppressed, thereby preventing the increase of edema.

The motion of the upper arm and the lower arm can be monitored. Through a certain period of detection, specific opinions and suggestions can be given to the patient according to the law of motion.

Embodiment 3 In a further typical embodiment of the present disclosure, as shown in FIG. 1 to FIG.

During the lifting motion, the force measuring unit of the muscle part changes most obviously; when edema occurs, the plurality of force measuring units in the circumferential direction change uniformly; and the pressure changes caused by the lifting motion and the edema are distinguished through the difference in measurement. Described above are merely preferred embodiments of the present application, and the present application is not limited thereto. Various modifications and variations may be made to the present application for those skilled in the art. Any modification, equivalent substitution, improvement or the like made within the spirit and principle of the present application shall fall into the protection scope of the present application.
