Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a hand massage rehabilitation device. Background Technology

[0002] As the most delicate and flexible motor organ in the human body, the integrity of the hand's function directly affects a patient's ability to perform daily activities and their quality of life. In clinical practice, hand dysfunction commonly occurs in the following situations: hemiplegia of the hand due to stroke sequelae, joint stiffness and muscle atrophy after hand fractures or tendon injuries, paralysis of intrinsic hand muscles caused by peripheral nerve damage, and chronic pain resulting from long-term hand strain. In addition to medication and surgery, systematic and scientific hand rehabilitation training and massage therapy are important means to promote functional recovery in addressing these hand dysfunctions.

[0003] Currently, there are some hand rehabilitation training and massage devices on the market, but a comprehensive analysis of existing technologies reveals the following common technical defects and shortcomings: Insufficient functional integration. Most existing devices have only one function, such as simple vibration massage or heat therapy. They cannot simultaneously perform multi-dimensional complex rehabilitation movements such as palm compression massage, independent finger compression massage, and passive finger traction and stretching training, making it difficult to meet the comprehensive training needs of muscles, joints, and tendons during hand rehabilitation.

[0004] The design of the finger airbag structure is unreasonable. Most of the finger airbags in existing devices have a uniform and symmetrical structure, which does not fully consider the anatomical characteristics of the human hand—there are significant differences in the depth of the finger groove and the thickness of the fingers between the index and little fingers. This results in poor fit of the airbag when wrapping the fingers, poor comfort when switching between left and right hands, and affects the massage effect and user experience.

[0005] The airbag assembly process is complex. In traditional equipment, each airbag is mostly an independent component, requiring separate installation and connection of air tubes. This not only makes the assembly process cumbersome and inefficient, but also increases the risk of air leakage and the failure rate, which is not conducive to cost control and reliability improvement of the product.

[0006] Lack of finger traction and extension function. Most existing hand massage devices only focus on pressure stimulation of the soft tissues of the hand, while neglecting passive traction and extension training of the finger joints. For postoperative rehabilitation of the hand and hemiplegic patients, passive stretching of the fingers is of great clinical significance for maintaining joint range of motion and preventing tendon adhesions and joint contractures, but existing devices cannot achieve the synergistic effect of massage and traction.

[0007] Therefore, we propose a hand massage rehabilitation device to address the problems mentioned above. Utility Model Content

[0008] The purpose of this invention is to provide a hand massage rehabilitation device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a hand massage rehabilitation device, comprising: an outer shell, and a controllable display screen fixedly mounted on the surface of the outer shell for electrical control and related data display of the entire device; A palm module is fixedly installed inside the outer shell, and an integrated airbag is installed inside the palm module for squeezing and massaging the palm. At the same time, a thumb module is installed on the side of the outer shell, and some of the integrated airbags are distributed inside the thumb module for squeezing and massaging the thumb. Inside the outer casing, a finger module is also linearly slidably installed. The finger module has a built-in finger airbag for squeezing and massaging the fingers. The integrated airbag can also drive the sliding of the finger module, which is used to pull the finger module to move and stretch the fingers.

[0010] Preferably, the controllable display screen includes a display screen, control buttons, and a circuit board. The circuit board is electrically connected to the air pump, the battery, and the air valve and air pipe assembly to realize the electrical control of each functional unit. The air pump, the battery, and the air valve and air pipe assembly are all fixedly installed between the outer shell and the interlayer of each module. The air pipe of the air valve and air pipe assembly is connected to the finger airbag and the integrated airbag.

[0011] Preferably, two thumb modules are provided, located on the two sides of the outer shell respectively, which is suitable for switching between the left and right hands, so that the thumbs can be squeezed and massaged.

[0012] Preferably, the finger module includes a finger support housing, a sliding clip integrally connected to the side of the finger support housing, the sliding clip being slidably connected to the outer housing, and the sliding clip being elastically connected to the outer housing by a spring or elastic band, for realizing the reset of the finger support housing after displacement.

[0013] Preferably, the finger airbag comprises four independent airbags, wherein the two outermost airbags have beveled openings at the ends facing the palm to accommodate the different finger groove depths of the index finger and little finger, so that they can fit the fingers when switching between the left and right hands.

[0014] Preferably, the integrated airbag is composed of several airbags cut from a single piece of fabric, which is easier to install and assemble than independent airbags. The integrated airbag includes two finger traction airbags that are symmetrically positioned vertically. The finger traction airbags are located between the finger support shell and the palm module shell. By inflating the finger traction airbags, the finger support shell is displaced, thereby stretching the fingers.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By integrating three major functions—palm squeezing massage, finger independent squeezing massage, and passive finger traction stretching—into one compact and comprehensive structure, multiple rehabilitation movements can be completed in one operation. This effectively solves the problem that existing equipment has limited functions and cannot meet the needs of comprehensive rehabilitation training, significantly improving the efficiency and effectiveness of hand rehabilitation training. 2. By setting slanted openings at the ends of the two outermost airbags facing the palm, the airbags can better adapt to the differences in the depth and thickness of the finger grooves when wrapping the index and little fingers. They can achieve a close fit regardless of whether the left or right hand is used, which greatly improves wearing comfort and massage effectiveness, reflecting excellent ergonomic design. 3. The integrated airbag structure, which consists of several airbags cut from a single piece of fabric, significantly reduces the number of scattered parts and air tube interfaces compared to traditional independent airbags. This simplifies the assembly process, reduces production costs and the risk of air leakage, and improves product consistency and reliability. 4. By utilizing the finger traction airbag set in the integrated airbag, the finger support shell is pushed outward by inflation and expansion while the palm is being squeezed and massaged, thus achieving synchronous passive traction and stretching of the fingers. This effectively prevents tendon adhesion and joint contracture, and is especially suitable for postoperative rehabilitation of the hand and early rehabilitation intervention for hemiplegic patients, expanding the clinical application scope of the device. 5. Thumb modules are set on both sides of the outer shell, making it easy to use with either hand without the need for additional adjustments to the device structure, making it flexible and convenient to use; at the same time, through the elastic reset design of springs or elastic bands, the finger support shell can automatically reset after the airbag in the finger area is deflated, realizing the alternating cycle of massage and traction, with a high degree of automation and a good user experience.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a hand massage rehabilitation device, including: an outer shell 1, and a controllable display screen 2 fixedly installed on the surface of the outer shell 1 for electrical control of the entire device and related data display; A palm module 6 is fixedly installed inside the outer shell 1. An integrated airbag 4 is installed inside the palm module 6 for squeezing and massaging the palm. At the same time, a thumb module 3 is installed on the side of the outer shell 1. Some of the airbags of the integrated airbag 4 are distributed inside the thumb module 3 for squeezing and massaging the thumb. The outer casing 1 also has a linearly sliding finger module 5. The finger module 5 has a built-in finger airbag 51 for squeezing and massaging the fingers. The integrated airbag 4 can drive the sliding of the finger module 5, which is used to pull the finger module 5 to move and stretch the fingers.

[0020] The integrated airbag 4 is constructed from a single piece of flexible polymer composite material, such as TPU-coated fabric, which is cut and then formed into independent inflatable chambers in a predetermined area through hot pressing or high-frequency welding. The chambers are connected by concealed airways pre-installed within the fabric or by external micro-air tubes, thus forming an integrated structure of multiple airbag units. This integrated airbag 4 is assembled onto the inner side of the palm module 6 in a ring-shaped manner, generating uniform pressure on the palm, back of the hand, and sides upon inflation. The airbag unit extending into the thumb module 3 inflates and deflates synchronously with the palm airbag unit, compressing the base of the thumb and the fingertip. Compared to separate airbags, this integrated airbag significantly reduces the number of air tube interfaces, greatly shortens assembly time, and ensures consistent deformation of each airbag unit, significantly reducing the risk of leakage.

[0021] In addition, two thumb modules 3 are provided, located on the two sides of the outer shell 1 respectively, which are suitable for switching between the left and right hands, so that the thumbs can be squeezed and massaged.

[0022] Specifically, such as Figure 2 As shown, the controllable display screen 2 includes a display screen, control buttons and a circuit board. The circuit board is electrically connected to the air pump 7, the battery 8 and the air valve and air pipe assembly 9 to realize the electrical control of each functional unit. The air pump 7, the battery 8, and the air valve and air pipe assembly 9 are all fixedly installed between the outer shell 1 and the interlayer of each module. The air pipe of the air valve and air pipe assembly 9 is connected to the finger airbag 51 and the integrated airbag 4.

[0023] like Figure 3 and Figure 5 As shown, the finger module 5 includes a finger support housing 52, and a sliding clip 521 is integrally connected to the side of the finger support housing 52. The sliding clip 521 is slidably connected to the outer housing 1, and the sliding clip 521 and the outer housing 1 are elastically connected by a spring or elastic band to realize the reset after the finger support housing 52 is displaced. The finger airbag 51 contains four independent airbags. The two outermost airbags have slanted openings 511 at the ends facing the palm. Since the depth of the finger grooves of the index finger and the little finger is different, the slant can better fit the fingers whether switching between the left and right hands, so that the fingers can get a better wrapping feeling and are more ergonomic.

[0024] like Figure 3 and Figure 4 As shown, the integrated airbag 4 is composed of several airbags cut from a single piece of fabric. Multiple airbags can be connected in series through air tubes, or a single airbag can be independently connected to an air valve. Compared with completely independent airbags, it is easier to install and assemble. The integrated airbag 4 includes two symmetrical finger traction airbags 41 located between the finger support housing 52 and the palm module 6 housing. By inflating the finger traction airbags 41, the finger support housing 52 is displaced, thereby stretching the fingers.

[0025] Working principle: After the device is started, the user sets parameters such as working mode, air pressure intensity and working time according to their own needs through the controllable display screen 2. The controllable display screen 2 includes a display screen, control buttons and circuit board. The circuit board controls the air pump 7 to start according to the set program, and supplies air to the integrated airbag 4 and the finger airbag 51 respectively through the various solenoid valves in the air valve and air pipe assembly 9 in a predetermined sequence, thereby realizing different combinations of massage and traction actions.

[0026] During palm and thumb massage, the air pump 7 inflates the integrated airbag 4 through the air valve and air pipe assembly 9. After the integrated airbag 4 expands, it exerts uniform pressure on the palm area covered by the palm module 6. At the same time, some of the airbags in the thumb module 3 of the integrated airbag 4 expand to squeeze and massage the thumb, thus achieving synchronous pressure stimulation of the palm and thumb.

[0027] During finger massage, the air pump 7 inflates the finger airbags 51 through the air valve and air tube assembly 9. After inflating, the finger airbags 51 wrap around and compress the user's four fingers (index, middle, ring, and little fingers), achieving uniform pressure around the fingers. The two outermost finger airbags 51 have a slanted opening 511 at the end facing the palm. This slanted opening 511 can accommodate the different finger groove depths of the index and little fingers, allowing the airbags to fit snugly against the corresponding fingers when switching between left and right hands, improving massage comfort and coverage.

[0028] During finger traction and stretching, the air pump 7 inflates two symmetrically positioned finger traction airbags 41 within the integrated airbag 4 via the air valve and air pipe assembly 9. The finger traction airbags 41 are located between the finger support housing 52 and the palm module 6. After inflating, the finger traction airbags 41 push the finger support housing 52 outwards. The finger support housing 52 slides linearly outwards along the outer housing 1 via a sliding latch 521, which is fitted into a guide groove on the inner wall of the outer housing 1. The spring or elastic band between the two is stretched when the finger traction airbags 41 are inflated, thereby passively displacing the user's fingers outwards, achieving traction and stretching training of the finger joints and tendons. When the finger traction airbags 41 deflate, the spring or elastic band between the sliding latch 521 and the outer housing 1 uses elastic restoring force to pull the finger support housing 52 back to its initial position, completing a full traction-reset cycle.

[0029] During the above process, the battery 8 provides power to the entire device, ensuring that the device can still operate normally in an environment without an external power source. The inflation and deflation of each airbag are precisely controlled by the solenoid valve in the air valve and air tube assembly 9, which can realize multiple working modes such as continuous pressurization, intermittent pressurization, and cyclic inflation and deflation to adapt to different rehabilitation stages and the personalized needs of users.

[0030] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
