Description

Technical Field

[0001] The invention relates to the technical field of medical treatment, in particular to an auxiliary exercise device after breast cancer surgery. Background Art

[0002] Upper limb lymphedema, shoulder joint dysfunction and other complications often occur after breast cancer surgery, and patients need to undergo comprehensive postoperative rehabilitation training for breast cancer. At present, postoperative activities for breast cancer in hospitals are basically not assisted by external equipment, and patients need to take the initiative to do so. However, due to the large psychological trauma of patients after surgery, their initiative and compliance in upper limb exercises are poor. There is an urgent need for a postoperative mobilization device for breast cancer to assist patients in upper limb exercises and prevent and manage lymphedema. Patent JP3234794U provides an upper limb auxiliary exercise device that can achieve multi-angle exercise. The device still has room for improvement. Patent CN212327333U discloses an upper limb function exerciser after breast cancer surgery, which assists exercise through pulleys, elastic bands and pull rings. The design of the auxiliary exercise device after breast cancer surgery should take into account adjustable exercise modes, safety monitoring, and easy operation. Summary of the invention

[0003] The purpose of the present invention is to provide a simple and automated upper limb function training device to solve the problem of upper limb lymphedema that often occurs after breast cancer surgery, which can achieve the coordinated promotion of lymphatic return by pressure and exercise.

[0004] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: an auxiliary exercise device for breast cancer surgery, comprising a fixed bracket and an auxiliary exercise module, the fixed bracket consisting of a vertical first frame and a second frame horizontally arranged on its top, the middle of the second frame is connected to a third frame perpendicular to it, telescopic frames are provided on both sides of the second frame, the telescopic frames are hinged to the first rods on both sides, the third frame is provided with guide rails and sliders, the sliders are hinged to the second rods on both sides, and the first rods and the second rods are both hinged to armrests. The present invention can realize the movement of the device in an electric manner, thereby driving the movement of the human body, or it can be pushed by the human body autonomously. In the latter case, the armrest drives the slider to move, thereby reducing the resistance during upper limb movement, step by step. It is worth noting that patients in the early stages of rehabilitation have little desire to exercise, and patients need to use exercise or external auxiliary devices to avoid problems such as lymphedema. The electric design of the present invention can help patients participate in rehabilitation training. The plan is as follows: the slider is set by the program to reciprocate on the guide rail, driving the rod to move the left and right armrests. In order to adapt to various body shapes, the telescopic frame of the second frame is provided with a protrusion, so that it is stuck in the groove of the second frame, and then the telescopic frame can slide on the second frame to adjust the distance of the armrests.

[0005] The armrest is provided with a second displacement sensor and a pressure sensor. The second displacement sensor is used to monitor the displacement of the armrest to obtain information such as movement frequency and shoulder joint movement angle. The pressure sensor on the side of the armrest is used to monitor the movement strength, and the device is automatically locked through the feedback of the pressure sensor to prevent joint injuries caused by sudden weakness of the patient.

[0006] A seat is provided below the third frame body. Massage air bags are provided on both sides of the backrest of the seat, and a controller is provided behind the backrest. The patient can put on the massage air bags on the arms, and the massage air bags can assist the rhythmic contraction of the peripheral skeletal muscles to promote lymphatic return.

[0007] The main body of the massage air bag is an armband connected with a fixing buckle. The inner side of the armband is provided with a first chamber and a second chamber. A temperature controller is arranged in the chamber. Air inlets and air outlets are arranged on the side wall of the chamber and are respectively connected to an air pump and a valve through pipelines. A controller is arranged between the massage air bag and the air pump, and the controller is connected to the second displacement sensor. The present invention improves the rehabilitation efficiency by combining movement and massage. The massage air bag can be used for pressure therapy. The ideal pressure treatment state for preventing lymphedema is: promoting lymphatic return through a high working pressure during muscle contraction, and maintaining a lower resting pressure during muscle relaxation to make the patient feel comfortable. For example, when the arm extends outward, the patient makes a voluntary movement, the muscles contract, and the massage air bag pressurizes to promote the return of lymph fluid; when moving in the reverse direction, the electric device assists, and the massage air bag decompresses. The cycle repeats, and the effect of promoting lymph fluid return is achieved through the combination of the pressure therapy and the device. Specifically as follows: The armband forms a sleeve through the fixing buckle, including a plurality of adjacent individually inflatable chambers arranged in sequence. The sleeve is fixed to the arm. The first chamber and the second chamber are inflated to a set chamber pressure through an air pump and a controller, and then deflated. The controller is electronic and programmable, and it receives the feedback from the second displacement sensor, that is, the inflation and deflation settings are made according to the position information of the armrest provided by the second displacement sensor. The valve can be an electromagnetic valve, which plays a role in flow regulation and can discharge the excess pressure to the atmosphere. The pressure of the first chamber can be different from that of the second chamber to provide a pressure gradient. There can be multiple chambers. The inflation and deflation times of each chamber are set according to the pressure therapy, and the inflation and deflation are carried out in sequence. The movement speed of the armrest needs to be set taking into account the operation of the massage air bag. In addition, temperature controllers are arranged in the first chamber and the second chamber, which can be temperature controllers based on semiconductor refrigeration chips, used to control the temperature of the chamber, and the temperature is displayed through a digital display card to avoid the temperature of the part where the patient's arm contacts the massage air bag from being too high and prevent high temperature from inducing edema.

[0008] The slider is provided with a first displacement sensor and a motor drive module. The first displacement sensor is used to feedback the displacement information of the slider and monitor the displacement range of the slider. The motor drive module can make the slider reciprocate according to the trajectory programmed by the control system.

[0009] Specifically, the second rod is a telescopic rod, and a laser distance sensor is provided at the fixed end. The laser distance sensor transmits signals to the controller. By adjusting the length of the second rod, the stroke of the armrest can be changed, and the patient can perform different modes of exercise with the aid of this device, such as chest expansion exercises. Generally, the length of the second rod needs to be greater than that of the first rod. The laser distance sensor can obtain the extended length information of the rod, and in combination with the first displacement sensor, it can determine the exercise mode. Different exercise modes have different shoulder joint movement angles and muscle contraction sites. The laser distance sensor transmits signals to the controller to regulate the pressure of each chamber of the massage airbag. By cooperating with the rhythmic contraction of the muscles in various parts of the arm, the pressure of each chamber is changed, thereby achieving the effect of synergistically promoting lymphatic return through exercise and massage.

[0010] Specifically, the first frame is hinged to the backrest of the seat through a limiting member and a movable limiting mechanism. The movable limiting mechanism is provided with a slidable sleeve on the outside of the first frame. The backrest of the seat is connected to the seat through a rotating shaft. The chair legs of the seat are composed of a first support at the front and a second support at the back. The first support is hinged to the bottom of the seat of the seat, and the second support is hinged to the first support. The seat is foldable, occupies a small space when not in use, and is convenient to carry. The limiting member and the movable limiting mechanism can play a role in stabilizing the seat during use. When not in use, the seat can be folded towards the backrest and retracted near the first frame.

[0011] Specifically, the second frame is connected to the third frame through a fixing member in the middle. The fixing member is provided with a rotating shaft. The third frame can rotate relative to the rotating shaft of the fixing member. The angle between the third frame and the first frame can be 0° to 120°. Due to the action of the rotating shaft damper, the third frame can be stationary at any angle within the limiting range. When the device is working, a pin is inserted at the connection between the fixing member and the third frame to make it stable. When in use, the angle between the third frame and the first frame can be adjusted to 90° or greater than 90° to conform to the physiological curvature of the human body. When not in use, the third frame can be folded to be parallel to the first frame, reducing the occupied space.

[0012] A display screen is connected to the front end of the third frame. The display screen can display the exercise time and frequency. The display screen is connected to the control system. Through program setting, the exercise intensity and exercise mode can be selected, and entertainment can also be provided to help the patient enhance the confidence in rehabilitation.

[0013] The beneficial effects of the present invention are as follows: An electric device is designed to drive the human body to move, solving the problems of poor initiative and compliance in the upper limb movement of patients; the movement amplitude of the patient's shoulder joint can be gradually changed through program setting; a massage airbag is designed, and the position information of the armrest is fed back to the controller through a displacement sensor and a laser range finder sensor, and the massage airbag can be adjusted according to the rhythmic contraction of the muscles during movement to synergistically promote the lymphatic return of the upper limb; a pressure sensor is designed for safety monitoring to avoid secondary injuries; the device has a high degree of intelligence, is easy to operate, can be stored and folded, and occupies a small space when not in use.

The telescopic frames 21 are hinged to the first rods 23 on both sides. A guide rail and a slider 31 are provided on the third frame body 3. The slider 31 is hinged to the second rods 32 on both sides. Both the first rod 23 and the second rod 32 are hinged to the handrail 5. The present invention can realize the movement of the device through an electric method, thereby driving the movement of the human body, or can be pushed by the human body independently. In the latter case, the handrail 5 drives the slider 31 to move, reducing the resistance during upper limb movement step by step. It should be noted that in the initial stage of rehabilitation, patients have little willingness to exercise, and patients need to exercise or use an external auxiliary device to avoid problems such as lymphedema. The electric design of the present invention can help patients participate in rehabilitation training. The solution is as follows: The slider 31 can make a reciprocating movement on the guide rail by program setting, driving the rods and thus making the left and right handrails 5 move. In order to adapt to various body types, the telescopic frame 21 of the second frame body is provided with a protrusion 22, which is stuck on the groove of the second frame body 2, and then the telescopic frame 21 can slide on the second frame body 2 to adjust the distance of the handrail 5.

[0024] The handrail 5 is provided with a second displacement sensor 51 and a pressure sensor 52. The second displacement sensor 51 is used to monitor the displacement of the handrail 5 to obtain information such as the movement frequency and the shoulder joint movement angle. The pressure sensor 52 on the side of the handrail 5 is used to monitor the movement force, and the device is automatically locked through the feedback of the pressure sensor 52 to prevent joint injuries caused by sudden weakness of the patient.

[0025] A seat 6 is provided below the third frame body 3. Massage air bags 8 are provided on both sides of the backrest of the seat 6, and a controller 7 is provided behind the backrest.

[0026] The slider 31 is provided with a first displacement sensor 34 and a motor drive module. The first displacement sensor 34 is used to feedback the displacement information of the slider 31 and monitor the displacement range of the slider 31. The motor drive module can make the slider 31 reciprocate according to the trajectory set by the programming of the control system.

[0027] Specifically, the first frame body 1 is hinged to the backrest of the seat 6 through a limiting member 61 and a movable limiting mechanism 62. The movable limiting mechanism 62 is provided with a slidable sleeve on the outer side of the first frame body 1. The backrest and the seat of the seat 6 are connected by a rotating shaft. The chair legs of the seat 6 are composed of a first support 63 at the front side and a second support 64 at the rear side. The first support is hinged to the bottom of the seat of the seat 6, and the second support 64 is hinged to the first support 63. The seat 6 can be folded, occupying a small space when not in use and being convenient for handling. The limiting member 61 and the movable limiting mechanism 62 can play a role in stabilizing the seat when in use. When not in use, the seat can be folded towards the backrest and retracted near the first frame body 1.

[0028] Specifically, the second frame body 2 is connected to the third frame body 3 through a fixing member 33 in the middle. The fixing member 33 is provided with a rotating shaft. The third frame body 3 can rotate relative to the rotating shaft of the fixing member 33. The angle between the third frame body 3 and the first frame body 1 can be 0° to 120°. Due to the action of the rotating shaft damper, the third frame body 3 can be stationary at any angle within the limiting interval. When the device works, a pin is inserted at the connection between the fixing member 33 and the third frame body 3 to make it stable. When in use, the angle between the third frame body 3 and the first frame body 1 can be adjusted to 90° or greater than 90° to conform to the physiological curvature of the human body. When not in use, the third frame body 3 can be folded to be parallel to the first frame body 1, reducing the occupied space.

[0029] A display screen 4 is connected to the front end of the third frame body 3. The display screen 4 can display the movement time and frequency. The display screen 4 is connected to the control system. Through program setting, the movement intensity and movement mode can be selected, and entertainment can also be provided to help the patient enhance the confidence in rehabilitation.

[0030] Embodiment 2 Such as Figure 5 , based on the further optimization of the pressure massage module and implementation method in Embodiment 1: The main body of the massage airbag 8 is an armband connected with a fixing buckle 83. The inner side of the armband is provided with a first chamber 81 and a second chamber 82. A thermostat is arranged in the chamber. An air inlet hole 84 and an air outlet hole 85 are arranged on the side wall of the chamber and are respectively connected with an air pump 9 and a valve 86 through pipelines. A controller 7 is arranged between the massage airbag 8 and the air pump 9. The controller 7 is connected with a second displacement sensor 51. The present invention improves the rehabilitation efficiency by combining motion and massage. The massage airbag 8 can be used for pressure therapy. The ideal pressure treatment state for preventing lymphedema: when the muscle contracts, the lymphatic return is promoted by a high working pressure, and when the muscle relaxes, a lower resting pressure is maintained to make the patient feel comfortable. For example, when the arm extends outwards, the patient makes a voluntary movement and the muscle contracts, and the massage airbag 8 pressurizes to promote the lymphatic fluid return; when moving in the reverse direction, the electric device assists, and the massage airbag 8 decompresses. It reciprocates and circulates to achieve the effect of promoting the lymphatic fluid return through the pressure therapy combination device. Specifically, the armband forms a sleeve through the fixing buckle 83, including a plurality of adjacent separately inflatable chambers arranged in sequence. The sleeve is fixed on the arm. The first chamber 81 and the second chamber 82 are inflated to the set chamber pressure by the air pump 9 and the controller 7, and then deflated. The controller 7 is electronic and programmable. It receives the feedback from the second displacement sensor 51, that is, the inflation and deflation settings are made according to the position information of the armrest 5 provided by the second displacement sensor 51. The valve 86 can be a solenoid valve, which plays a role in flow regulation and can discharge the excess pressure to the atmosphere. The pressure of the first chamber 81 can be different from that of the second chamber 82 to provide a pressure gradient. The chambers can be multiple. The inflation and deflation times of each chamber are set according to the pressure therapy, and the inflation and deflation are carried out in sequence. The movement speed setting of the armrest 5 needs to take into account the operation of the massage airbag 8. In addition, the first chamber 81 and the second chamber 82 are provided with thermostats, which can be temperature controllers based on semiconductor refrigeration chips, used to control the temperature of the chamber, and the temperature is displayed by a digital display card to avoid the temperature of the contact part between the patient's arm and the massage airbag 8 being too high and prevent high temperature from inducing edema.

[0031] Preferably, the second rod 32 is a telescopic rod, and a laser distance sensor is arranged at the fixed end. The laser distance sensor transmits the signal to the controller 7. By adjusting the length of the second rod 32, the stroke of the armrest 5 can be changed. The patient can perform different modes of movement with the help of this device, such as chest expansion movement, as Figure 3 and Figure 4 shown. Generally, the length of the second rod 32 needs to be greater than that of the first rod 23. The laser distance sensor can obtain the extended length information of the rod, and combined with the first displacement sensor 34, the motion mode can be judged. The shoulder joint motion angle and the muscle contraction part are different in different motion modes. The laser distance sensor transmits the signal to the controller 7 to regulate the pressure of each chamber of the massage airbag 8, and by cooperating with the rhythmic contraction of the muscles of each part of the arm, the pressure of each chamber is changed, so as to achieve the effect of promoting lymphatic return by the coordinated action of motion and massage.
