Description

Technical Field

[0001] This utility model relates to the field of rehabilitation assistive device technology, specifically an upper limb edema recovery device. Background Technology

[0002] Breast surgery is a branch of clinical surgery that focuses on the surgical aspects of breast diseases, including breast anatomy, breast infections, breast tumor pathology, and the diagnosis and treatment of breast tumors. After breast surgery, patients may experience swelling in their upper limbs. To alleviate pain and discomfort, the arm should be massaged to promote lymphatic drainage and reduce fluid retention.

[0003] Chinese patent CN218943819U discloses an auxiliary device for the recovery of upper limb edema. The device involves inserting the edematous arm into a rotating cylinder, which is driven by a geared motor to rotate. The massage heads on the rotating cylinder can massage the arm evenly, promote the flow of body fluids, and play an auxiliary role in the recovery of edema. The patient can also extend and retract the arm inside the rotating cylinder to massage different parts of the arm. The operation is convenient and quick.

[0004] However, the massage head in the aforementioned patent is in a relatively fixed position. Although the spring setting gives it the ability to stretch, the spring will have different degrees of contraction for upper limbs of different thicknesses, resulting in different pressure on the upper limb and thus different massage effects. It is difficult to effectively promote the recovery of upper limb edema. Utility Model Content

[0005] The purpose of this invention is to provide a device for the recovery of upper limb edema.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] An upper limb edema recovery device includes a base. Fixed cylinders are mounted on both sides of the upper surface of the base, and a rotating cylinder is rotatably connected between the two fixed cylinders. A geared motor is mounted on the upper surface of the base, and a pulley assembly is provided between the output shaft of the geared motor and the rotating cylinder. Multiple mounting posts are mounted on the outer surface of the rotating cylinder, arranged in three groups along the length of the rotating cylinder. Guide rods are inserted inside the mounting posts. Limit grooves are formed on the inner walls of both sides of the mounting posts. Limit blocks are mounted on the outer surfaces of both sides of the guide rods, and the limit blocks are positioned within the limit grooves. A first spring is installed inside the limit grooves, with its two ends abutting against the inner wall of the limit groove and the limit blocks, respectively. A massage head is provided at the bottom of the guide rod, and a wedge-shaped block is mounted at the top of the guide rod. An adjustment mechanism capable of compressing and engaging the wedge-shaped block is provided on the outer sides of the two fixed cylinders.

[0008] Therefore, by adjusting the wedge block, the wedge block can be squeezed downwards, and the massage head can be moved via the guide rod, thus achieving the purpose of adjusting the height of the massage head. This can meet the needs of patients with upper limbs of different sizes, ensuring appropriate massage intensity. In addition to the rotary cylinder driven by the geared motor to rotate and drive the massage head to perform circular massage on the upper limb, the wedge block can also be squeezed back and forth by the adjustment mechanism to drive the massage head to reciprocate and extend, providing a pressing massage to the patient's upper limb. The combination of circular and pressing massage can meet the different massage needs of patients, offering high flexibility and functionality, and effectively promoting the recovery of upper limb edema.

[0009] Furthermore, the adjustment mechanism includes four U-shaped rods coaxially arranged on the outer surfaces of the two fixed cylinders. The outer surface of the rotating cylinder is provided with three extrusion rings, which are respectively extruded and engaged with three sets of wedge blocks. Four side plates are installed on the outer surface of the extrusion rings, and the side plates are slidably installed on the outer surface of the U-shaped rods. Adjacent side plates are connected by connecting plates. An electric push rod is installed on the outer surface of the U-shaped rods, and the end of the telescopic end of the electric push rod is connected to the extrusion ring.

[0010] Furthermore, the extrusion ring has balls evenly installed on one side facing the wedge block.

[0011] Furthermore, the guide rod has an inner cavity, and an insert rod is slidably positioned inside the inner cavity. The massage head is installed at the end of the insert rod. A second spring is installed inside the inner cavity, and the two ends of the second spring abut against the inner wall of the inner cavity and the insert rod, respectively.

[0012] Furthermore, a guide post is installed inside the limiting groove, and the limiting block is slidably installed on the guide post, with the first spring sleeved on the outer surface of the guide post.

[0013] Furthermore, a protective cover is installed on the outer surface of both fixed cylinders, and the protective cover is placed on the outside of the adjustment mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model uses an adjustment mechanism to compress a wedge-shaped block, thereby driving the wedge-shaped block to move downwards. A guide rod then moves the massage head, allowing for height adjustment. This caters to patients with upper limbs of varying sizes, ensuring appropriate massage intensity. Furthermore, the rotating cylinder, driven by a geared motor, rotates to provide circular massage to the upper limb. The adjustment mechanism also reciprocates by compressing the wedge-shaped block, causing the massage head to extend and retract, providing a pressing massage to the patient's upper limb. This combination of circular and pressing massage caters to diverse patient needs, offering high flexibility and functionality, and effectively promoting the recovery of upper limb edema.

[0016] 2. By incorporating a rod and a second spring, this invention allows the massage head to contact the patient's upper limb. As the guide rod continues to descend, the second spring gradually compresses, and the thrust generated by the compression of the second spring alters the pressure exerted by the massage head on the patient's upper limb. This enables more precise adjustment of the massage intensity and allows the design to adapt to the structural shape of the upper limb. Attached Figure Description

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] like Figure 1-6As shown, an upper limb edema recovery device includes a base 100. Fixed cylinders 101 are mounted on both sides of the upper surface of the base 100. A rotating cylinder 102 is rotatably connected between the two fixed cylinders 101. A reduction motor 103 is mounted on the upper surface of the base 100. A pulley assembly 104 is provided between the output shaft of the reduction motor 103 and the rotating cylinder 102. Multiple mounting posts 105 are mounted on the outer surface of the rotating cylinder 102, arranged in three groups along the length of the rotating cylinder 102. Guide rods 106 are inserted inside the mounting posts 105. Limiting grooves 107 are formed on the inner walls of both sides of the mounting posts 105. Limiting blocks 108 are mounted on the outer surfaces of both sides of the guide rods 106, and the limiting blocks 108 are disposed within the limiting grooves 107. A first spring 109 is disposed inside the limiting grooves 107, with both ends of the first spring 109 abutting against the inner wall of the limiting groove 107 and the limiting blocks 108, respectively. A massage head 110 is provided at the bottom of the guide rod 106, and a wedge block 111 is installed at the top of the guide rod 106. An adjustment mechanism 200 capable of squeezing and engaging the wedge block 111 is provided on the outer side of the two fixed cylinders 101.

[0028] In use, the patient inserts their upper limb into the rotating cylinder 102. The adjustment mechanism 200 presses the wedge block 111, causing it to move downwards. This, in turn, moves the massage head 110 inwards via the guide rod 106. When the adjustment mechanism 200 reduces pressure on the wedge block 111, the first spring 109's elastic force causes the massage head 110 to move upwards, thus adjusting the height of the massage head 110 to suit patients with different upper limb sizes and ensuring appropriate massage intensity. The geared motor 103 is started, which drives the rotating cylinder 102 to rotate through the pulley group 104, so that the massage head 110 can perform a circular massage on the upper limb. When a pressing massage is needed on the patient's upper limb, the wedge block 111 is reciprocated by the adjustment mechanism 200, which can drive the massage head 110 to reciprocate and extend to perform a pressing massage on the patient's upper limb. The circular massage and pressing can be performed at the same time, so as to meet the different massage needs of the patient. It is flexible and functional, and can effectively promote the recovery of upper limb edema.

[0029] Specifically, the adjusting mechanism 200 includes four U-shaped rods 201 coaxially mounted on the outer surfaces of two fixed cylinders 101. The outer surface of the rotating cylinder 102 is provided with three compression rings 202, which are respectively compressed into three sets of wedge blocks 111. Four side plates 203 are mounted on the outer surface of the compression rings 202, and these side plates 203 are slidably mounted on the outer surface of the U-shaped rods 201. Adjacent side plates 203 are connected by a connecting plate 204. An electric push rod 205 is mounted on the outer surface of the U-shaped rods 201, and the end of the electric push rod 205 is connected to the compression rings 201. 02 Connection: When it is necessary to adjust the height of the massage head 110, the electric push rod 205 can be activated. The electric push rod 205 drives the compression ring 202 connected to it to move horizontally. Since the three compression rings 202 are connected by the connecting plate 204, they can move horizontally at the same time and squeeze the wedge block 111, so as to achieve the purpose of adjusting the height of all massage heads 110 at the same time. Since the side plate 203 is slidably installed on the U-shaped rod 201, the stability of the compression ring 202 structure can be ensured, so that it maintains the angle during the translation and compression process, and ensures that the height of all massage heads 110 is consistent.

[0030] Specifically, the compression ring 202 is evenly equipped with ball bearings 300 on the side facing the wedge block 111. By setting the ball bearings 300, the friction between the compression ring 202 and the wedge block 111 can be greatly reduced, thus ensuring the smoothness of the wedge block 111 during rotation.

[0031] Specifically, the guide rod 106 has an inner cavity 400, and an insert rod 401 is slidably positioned inside the inner cavity 400. The massage head 110 is installed at the end of the insert rod 401. A second spring 402 is installed inside the inner cavity 400. The two ends of the second spring 402 abut against the inner wall of the inner cavity 400 and the insert rod 401, respectively. With the insertion rod 401 and the second spring 402, when the massage head 110 contacts the patient's upper limb, the second spring 402 will gradually compress as the guide rod 106 continues to descend. The thrust generated by the compression of the second spring 402 changes the pressure exerted by the massage head 110 on the patient's upper limb, thereby enabling more precise adjustment of the massage intensity and adapting to the structural shape of the upper limb.

[0032] Specifically, a guide post 500 is installed inside the limiting groove 107, and a limiting block 108 is slidably installed on the guide post 500. The first spring 109 is sleeved on the outer surface of the guide post 500. The guide post 500 can provide a limiting and guiding function for the first spring 109, so that it remains stable during compression and avoids bending deformation.

[0033] Specifically, a protective cover 600 is installed on the outer surface of both fixed cylinders 101, and the protective cover 600 covers the outside of the adjustment mechanism 200. By setting the protective cover 600, the adjustment mechanism 200 and components such as the wedge block 111 can be shielded to avoid collisions that could cause injury during use.

[0034] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
