Description

Technical Field

[0001] This invention relates to the field of therapeutic device technology, specifically to an adjustable pressure wearable treatment device for post-mastectomy lymphedema. Background Technology

[0002] As an important means of treating breast cancer, breast cancer surgery often requires the removal of some lymph nodes. This operation inevitably disrupts the lymphatic circulation system of the upper limb, causing obstruction of lymphatic fluid return and abnormal accumulation in the interstitial spaces of the upper limb, which in turn leads to upper limb lymphedema. If upper limb lymphedema is not treated in a timely and effective manner, it will lead to a series of serious clinical consequences.

[0003] Traditional treatments for lymphedema are highly dependent on the operator's experience. Inconsistent techniques, pressure, direction, and rhythm can lead to fluctuating efficacy. A single treatment requires 30-60 minutes of professional operation, and patients need to frequently travel to and from the hospital.

[0004] Static compression leads to low reflux efficiency. The cuff only provides uniform pressure and cannot directionally push lymph fluid. Patients may also experience skin damage and nerve compression. The lack of gravity drainage synergy limits the therapeutic effect.

[0005] Disorderly inflation and deflation of the balloon can cause lymphatic fluid turbulence. Fixed-size balloons cannot match the changes in limb circumference after surgery, making patients prone to fatigue and drooping, which affects gravity drainage.

[0006] Pressure cuffs require assistance to put on and take off, and static pressure can cause numbness and pain, leading most patients to discontinue treatment. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an adjustable pressure wearable treatment device for lymphedema after breast cancer surgery, which solves the problems of traditional lymphedema treatment being highly dependent on manual experience and inefficient, and static compression devices having problems such as failure of directional drainage and poor adaptability.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pressure wearable treatment device for post-mastectomy lymphedema, comprising: Shoulder support frame for shoulder support of adjustable pressure post-mask lymphedema treatment device; The traction crankshaft is located in the shoulder sleeve and is used to create a limiting structure for the patient to raise their arm vertically; The treatment device is located in the shoulder frame, and the rotating seat of the shoulder frame is used to attach the treatment part of the patient's upper arm; The end-positioning mechanism is located in the shoulder sleeve, and works with the damping hydraulic component 2 and the extended hinge frame to fix the patient's forearm area and ensure the arm is straight. The compression and restriction mechanism is located in the shoulder sleeve, and works with the upper arm opposing frame, double helical screw and limiting sleeve to form a multi-directional compression structure for the edematous part of the patient's upper arm; The clamping drive mechanism is located on the shoulder sleeve and works with the fixed-axis structure of the limiting sleeve, the opposing parallel channel, the embedded ring frame and the inner extension slide to control the clamping state of the edematous part when the device is pushed, so as to form a unidirectional pushing state.

[0009] Preferably, the shoulder support frame is a semi-enclosed frame structure, and the rotating seat is located at the bottom of the shoulder support frame. The traction crankshaft is fixed to the bottom rotating seat of the shoulder support frame in an inclined manner. The treatment limiting mechanism is rotatably mounted on the rotating shaft of the shoulder support frame. The end positioning mechanism is hinged to the end of the treatment limiting mechanism away from the shoulder support frame. The clamping limiting mechanism is embedded in the treatment limiting mechanism. The clamping drive mechanism is sleeved on the clamping limiting mechanism.

[0010] Preferably, the shoulder strap has a diagonal cross strap on the side wall, which can be worn at an angle under the patient's opposite armpit.

[0011] Preferably, the treatment limiting mechanism includes an upper arm opposing frame and a second damping hydraulic component. The upper arm opposing frame is composed of opposing side plates, and its top end rotates on the pivot of the shoulder sleeve frame. The extension hinge frame rotates at the end of the upper arm opposing frame away from the shoulder sleeve frame. A first damping hydraulic component rotates on the side wall of the extension hinge frame near the upper arm opposing frame. The telescopic end of the first damping hydraulic component, away from the extension hinge frame, rotates on the protruding end of the traction crankshaft. The second damping hydraulic component rotates on the side wall of the upper arm opposing frame. The double helical screw rotates on one side plate structure of the upper arm opposing frame. The limiting sleeve is fixed on the opposing side plate of the upper arm opposing frame. The opposing parallel channel is provided on the inner wall of the limiting sleeve.

[0012] Preferably, the end positioning mechanism includes a side fixing frame, which is rotatably located at the end of the extension hinge frame. A protruding extension rod is fixed to the side wall of the side fixing frame, and one end of the extension rod is rotatably located on the telescopic end of the damping hydraulic component.

[0013] Preferably, the clamping and limiting mechanism includes an embedded ring frame, which is embedded and slides within the opposing frame of the main arm and is also placed within the limiting sleeve. The surface of the embedded ring frame is provided with circumferentially distributed guide channels. A single ball bearing sleeve is fixed to the side of the embedded ring frame, and the single ball bearing sleeve is spirally connected to the double helical screw. The inner extension slide is in multiple sets and is circumferentially distributed and slides along the guide channels of the embedded ring frame. At the same time, a fixed axis structure is provided on the side wall of the inner extension slide and passes through the guide channels of the embedded ring frame.

[0014] Preferably, the clamping drive mechanism includes a linkage ring, which is sleeved and rotated on the side wall of the embedded ring frame. The linkage ring is provided with oblique arc grooves corresponding to the number and position of the inner extension slides.

[0017] Preferably, the inner end of the inner extension carriage is fixed with a tight-fitting arc plate, and the tight-fitting arc plate is provided with an independently controlled arc-shaped airbag structure.

[0018] This invention provides an adjustable pressure wearable treatment device for post-mastectomy lymphedema. It has the following beneficial effects: 1. This invention features directional lymphatic drainage therapy: a traction crankshaft, in conjunction with dual-damping hydraulic components, and two forced arms are raised straight above the heart. Gravity and mechanical compression are used to promote drainage through a dual-pathway mechanism. The clamping and limiting mechanism's attached arc plate maintains a circumferential compression as it moves toward the shoulder, ensuring unidirectional flow of lymph. The clamping drive mechanism, through the inclined groove design of the opposing parallel channels, automatically releases the compression at the end, preventing lymph backflow. 2. This invention has dynamic pressure adaptive adjustment capability: the independent airbag structure of the forearm loop and the tightly attached arc plate automatically inflates and deflates according to the limb circumference to adapt to changes in postoperative limb swelling; the radial movement of the inner extension slide provides basic mechanical pressure; the airbag filling finely adjusts the pressure distribution and eliminates pressure blind spots. 3. This invention has fully automatic treatment cycle capability: the treatment process requires zero manual operation. The linkage ring of the compression drive mechanism automatically completes the switching of compression, release, reset and re-compression states under the guidance of the inclined groove of the limiting sleeve, without the need for external intervention. The double helical screw converts the motor rotation into linear motion, and works with the single ball bearing sleeve to achieve low-friction pushing. 4. The present invention has wearing stability: the shoulder support of the shoulder frame, the opposite armpit fixation of the diagonal strap and the forearm locking of the end positioning mechanism form an anti-displacement triangular structure, and the damping hydraulic components form a rigid connection to counteract the micro-movements caused by arm muscle tremors. 5. The present invention has multiple safeguards for treatment safety: the compression mechanism automatically releases the compression when it moves to the end of the upper arm to avoid compression of the cubital fossa nerve and blood vessel plexus; the length of the inclined groove of the opposing parallel channel limits the maximum rotation angle of the linkage ring to prevent excessive pressure release from causing dislocation of the inner extension slide. 6. This invention has intelligent state switching capability: the quadrilateral closed-loop design of the opposing parallel channels realizes automatic switching between extrusion and decompression through a purely mechanical structure, the damping hydraulic components provide quiet and stable lifting arm, and the double helical screw realizes high-precision extrusion displacement. The two work together to solve the problem of lifting arm and extrusion action. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides an adjustable pressure wearable treatment device for post-mastectomy lymphedema, comprising: a shoulder sleeve 1 for supporting the wear of the adjustable pressure wearable treatment device for post-mastectomy lymphedema; a traction crankshaft 2 located on the shoulder sleeve 1 to form a limiting structure for the patient to raise their arm vertically; the shoulder sleeve 1 is a semi-enclosed sleeve structure, with a rotating seat located at the bottom of the shoulder sleeve 1; the traction crankshaft 2 is fixed to the bottom rotating seat of the shoulder sleeve 1 in an inclined manner; and the side wall of the shoulder sleeve 1 is provided with a diagonal strap 3, which can be tilted... Wearing under the opposite armpit of the patient, this treatment device is mainly designed for the treatment of edema in the upper arm of breast cancer patients after surgery in a portable form. When worn by the patient, the entire device is in a vertical position. The patient attaches the shoulder sleeve 1 at the top of the device to the shoulder of the edematous area, and then wraps the diagonal strap 3 attached to the shoulder sleeve 1 around the head and diagonally across the opposite armpit. The support of the shoulder sleeve 1 by the shoulder and the fastening of the diagonal strap 3 to the shoulder sleeve 1 allow the device to be quickly put on the patient's upper body.

[0023] Please see the appendix Figure 1 -Appendix Figure 4The treatment limiting mechanism 4 is rotatably mounted on the pivot of the shoulder sleeve 1. The end-positioning mechanism 5 is hinged to the end of the treatment limiting mechanism 4 away from the shoulder sleeve 1. The clamping limiting mechanism 6 is embedded in the treatment limiting mechanism 4. The clamping drive mechanism 7 is sleeved on the clamping limiting mechanism 6. The patient's arm passes through the treatment limiting mechanism 4, which is rotatably mounted on the pivot of the shoulder sleeve 1, and through the clamping limiting mechanism 6 and the clamping drive mechanism 7 installed inside the treatment limiting mechanism 4, until the forearm extends to the end-positioning mechanism 5 rotatably mounted at the end of the treatment limiting mechanism 4. The elbow is located between the treatment limiting mechanism 4 and the end-positioning mechanism 5, and the end-positioning mechanism 5 is used to hold the patient's forearm. The edematous upper arm is located within the treatment limiting mechanism 4 and is surrounded by the clamping limiting mechanism 6 and the clamping drive mechanism 7. The hydraulic structure included in the treatment limiting mechanism 4 uses hydraulic traction to keep the patient's arm straight. In the initial state, after wearing the device, the entire arm is simultaneously raised straight up, as high as possible above the patient's heart, to facilitate lymphatic drainage. Simultaneously, the treatment limiting mechanism 4 drives the internal compression limiting mechanism 6 and compression driving mechanism 7 to move back towards the shoulder area of ​​the upper arm. The compression limiting mechanism 6, through the compression driving mechanism 7, forms a circumferential compression state, pressing the arm while squeezing lymphatic fluid back towards the shoulder. As the compression limiting mechanism 6 and compression driving mechanism 7 move to the end of the upper arm of the treatment limiting mechanism 4, the compression driving mechanism 7 rotates under the guidance of the treatment limiting mechanism 4, causing the compression limiting mechanism 6 to release its compression state and move in the opposite direction, following the drive of the treatment limiting mechanism 4, until it returns to its original starting point. Then, the treatment limiting mechanism 4 pulls the compression driving mechanism 7 to rotate again, causing the compression limiting mechanism 6 to return to the circumferential compression state and move in the opposite direction again to push and massage, thus achieving a reciprocating compression and lymphatic drainage state.

[0024] Please see the appendix Figure 4The treatment limiting mechanism 4 includes an upper arm opposing frame 41 and a second damping hydraulic component 44. The upper arm opposing frame 41 is composed of opposing side plates, serving as a sliding track for the clamping mechanism, and its top end rotates on the pivot of the shoulder sleeve 1. The extension hinge frame 42 rotates at the end of the upper arm opposing frame 41 away from the shoulder sleeve 1. The extension hinge frame 42 has a damping hydraulic component 43 rotating near the side wall of the upper arm opposing frame 41. The telescopic end of the damping hydraulic component 43 away from the extension hinge frame 42 rotates at the protruding end of the traction crankshaft 2. The second pressure component 44 rotates on the side wall of the upper arm opposing frame 41, and the traction crankshaft 2 is tilted and fixed to the bottom rotating seat of the shoulder sleeve frame 1. It is connected to the extension hinge frame 42 located at the end of the treatment limiting mechanism 4 through the first damping hydraulic component 43. One end of the second damping hydraulic component 44 is fixed to the side wall of the upper arm opposing frame 41, and the other end is connected to the extension protrusion 52 of the end positioning mechanism 5. The hydraulic components contract synchronously, pulling the extension hinge frame 42 and the end positioning mechanism 5, so that the arm is kept straight and raised to a position higher than the heart, promoting the centripetal return of lymph fluid.

[0025] Please see the appendix Figure 4 -Appendix Figure 8 The double helical screw 45 rotates on the side plate structure of the upper arm opposing frame 41, driven by a motor. The limiting sleeve 46 is fixed on the opposite side plate of the upper arm opposing frame 41. The opposing parallel channel 47 is set on the inner wall of the limiting sleeve 46. The opposing parallel channel 47 is a quadrilateral channel structure composed of relatively parallel straight channels and relatively parallel inclined channels. The inclined channels are located at both ends of the limiting sleeve 46. The straight section of the channel in the middle is parallel to the upper arm axis, and the inclined section of the channel at both ends is inclined at an angle. The patient's upper arm is placed in the internal space of the upper arm opposing frame 41, and the elbow is locked in front of the end positioning mechanism 5. The second damping hydraulic component 44 retracts, and the end positioning mechanism 5 is tightened through the extension protrusion 52. The first damping hydraulic component 43 keeps the arm straight. The double helical screw 45 rotates to drive the clamping mechanism. The parallel channel 47 of the limiting sleeve 46 controls the switching of the clamping state.

[0026] Please see the appendix Figure 4 -Appendix Figure 5 The end-positioning mechanism 5 includes a side fixing frame 51, which rotates at the end of the extension hinge frame 42 and can rotate with the arm. A protruding extension rod 52 is fixed on the side wall of the side fixing frame 51. One end of the extension rod 52 rotates on the telescopic end of the damping hydraulic component 44. The extension rod 52 is pulled by the damping hydraulic component 44 and locks the position of the forearm together with the forearm loop 53. The forearm loop 53 is fixed on the outside of the side fixing frame 51, and the forearm loop 53 has an annular airbag structure inside. After inflation, it adaptively wraps around the forearm to avoid compressing the nerve.

[0027] Please see the appendix Figure 8 -Appendix Figure 11The clamping and limiting mechanism 6 includes an embedded ring frame 61, which is embedded and slides within the upper arm opposing frame 41 and is also placed within the limiting sleeve 46. The surface of the embedded ring frame 61 is provided with circumferentially distributed guide channels. A single ball bearing sleeve 62 is fixed to the side of the embedded ring frame 61, and the single ball bearing sleeve 62 is spirally sleeved on the double helical screw 45. The spiral engagement of the double helical screw 45 converts the rotational motion into linear displacement. There are multiple sets of inner extension slides 63, which are circumferentially distributed and slide along the guide channels of the embedded ring frame 61. At the same time, a fixed axis structure is provided on the side wall of the inner extension slide 63 and passes through the guide channels of the embedded ring frame 61. A tight-fitting arc plate 64 is fixed to the inner end of the inner extension slide 63, and an independently controlled arc-shaped airbag structure is provided in the tight-fitting arc plate 64. The rotation of the double helical screw 45 drives the single ball bearing sleeve 62 to drive the embedded ring frame 61 to move along the upper arm towards the shoulder.

[0028] Radial compression: The inner extension slide 63 is controlled by the inclined arc groove 72 of the linkage ring 71. The centripetal contraction drives the airbag of the tightly attached arc plate 64 to inflate, and the circumferential compression of the edematous upper arm.

[0029] Lymphatic fluid propulsion: In the compression state, the embedded ring frame 61 moves towards the shoulder, and the attached arc plate 64 propels the lymphatic fluid toward the shoulder.

[0030] Please see the appendix Figure 8 -Appendix Figure 12 The pressing drive mechanism 7 is located on the shoulder sleeve 1 and works with the fixed axis structure of the limiting sleeve 46, the opposing parallel channel 47, the embedded ring frame 61 and the inner extension slide 63. It is used to control the pressing state of the edema part when the device is pushed to form a unidirectional pushing state. The pressing drive mechanism 7 includes a linkage ring 71, which is sleeved and rotated on the side wall of the embedded ring frame 61. The linkage ring 71 is provided with oblique arc grooves 72 corresponding to the number and position of the inner extension slide 63. The side wall of the linkage ring 71 is fixed with a traction pin 73, and the traction pin 73 is embedded and slidably inserted in the opposing parallel channel 47. Extrusion stage: The traction pin 73 slides in the straight groove and restricts the linkage ring 71 from rotating. The inclined arc groove 72 forces the inner extension slide 63 to slide in the center of the fixed axis so as to adhere tightly to the arc plate 64 to maintain extrusion. End pressure relief: The embedded ring frame 61 moves to the elbow end of the boom, causing the traction pin 73 to slide into the inclined groove. The groove wall forces the linkage ring 71 to rotate, and the angle of the inclined arc groove 72 changes, causing the inner extension slide 63 to slide outward along the groove, causing the tightly attached arc plate 64 to release the pressure.

[0031] Please see the appendix Figure 1 -Appendix Figure 13 The working principle includes the following steps: S1. Shoulder fixation steps: The patient puts the semi-enclosed shoulder brace 1 on the affected shoulder and fixes it by wrapping the diagonal strap 3 around the head and under the armpit of the healthy side to form stable support; S2, Arm positioning steps: The affected arm passes through the treatment limiting mechanism 4, the elbow is placed between the treatment limiting mechanism 4 and the end positioning mechanism 5, the forearm is fixed by the forearm loop 53 of the end positioning mechanism 5 and the pressure of the ring-shaped airbag, and the edema area of ​​the upper arm is located inside the treatment limiting mechanism 4. S3, Arm Lifting and Straightening Fixation Mechanism: The traction crankshaft 2 is tilted and fixed to the bottom rotating seat of the shoulder frame 1. It is connected to the extension hinge frame 42 located at the end of the treatment limiting mechanism 4 via the damping hydraulic component 1 43. One end of the damping hydraulic component 2 44 is fixed to the side wall of the upper arm opposing frame 41, and the other end is connected to the extension protrusion 52 of the end positioning mechanism 5. The hydraulic components contract synchronously, pulling the extension hinge frame 42 and the end positioning mechanism 5, so that the arm is kept straight and raised to a position higher than the heart, promoting the centripetal return of lymph fluid. S4. Reciprocating compression treatment mechanism for edema area: The double helical screw 45 is driven to rotate by a motor, which drives the single ball bearing sleeve 62 to move along the screw axis. The inner ring frame 61 meshes with the double helical screw 45 through the single ball bearing sleeve 62 and moves along the upper arm opposing frame 41 towards the shoulder. The inner extension slide 63 is embedded in the guide channel of the inner ring frame 61 through a fixed axis structure. The end of the tight-fitting arc plate 64 contains an independent airbag that fits tightly against the upper arm. S5, Extrusion State Control: The linkage ring 71 of the compression drive mechanism 7 is sleeved on the outside of the inner ring frame 61. Its inclined arc groove 72 meshes with the fixed axis structure of the inner extension slide 63. The traction clamping shaft 73 is fixed on the side wall of the linkage ring 71 and embedded in the opposing parallel channel 47 of the limiting sleeve 46. The opposing parallel channel 47 is a quadrilateral closed loop formed by the middle section of two parallel straight grooves and the two ends of two inclined grooves. S6, Forward Extrusion Stage: The double helical screw 45 drives the embedded ring frame 61 to move towards the shoulder, the traction pin 73 is located in the straight groove section of the limiting sleeve 46, the linkage ring 71 does not rotate, the inclined arc groove 72 forces the inner extension slide 63 to retract radially, tightly adhering to the arc plate 64 to squeeze the upper arm, and push the lymph fluid back towards the shoulder. S7. End pressure relief and steering: When the inner ring frame 61 moves to the end of the boom near the elbow, the traction pin 73 slides into the inclined groove section of the limiting sleeve 46; the inclined groove forces the linkage ring 71 to rotate, and the angle of the inclined arc groove 72 changes to guide the inner extension slide 63 to slide along the groove outward on the fixed axis, and the tightly attached arc plate 64 releases the pressure. S8, Reverse Reset Stage: When the single ball bearing sleeve 62 is displaced to the end of the double helical screw 45, its directional thread will guide the single ball bearing sleeve 62 and the embedded ring frame 61 to reset towards the elbow. The traction pin 73 rotates twice in the inclined groove on the other side, driving the angle of the inclined arc groove 72 to reset. At the same time, the inner extension slide 63 retracts again, preparing for the next round of compression. Driven by the screw, the centripetal compression-release-reset-recompression cycle is realized, simulating artificial lymphatic drainage. The airbags of the forearm ring sleeve 53 and the tightly attached arc plate 64 are inflated and deflated according to the limb thickness to ensure fixation and uniform pressure. Damping hydraulic component 1 43 and damping hydraulic component 2 44 maintain the arm lifting angle to avoid displacement during treatment. The inclined groove design of the opposing parallel channel 47 is the core of the compression / release state switching, and radial movement is realized by the rotation of the linkage ring.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
