Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a portable device for treating hand edema with circulatory pressure therapy and alternating hot and cold compresses. Background Technology

[0002] Swelling of the hand is a common complication after surgery, trauma, lymphatic drainage disorders, or certain chronic diseases. Persistent swelling not only causes pain and limited joint movement but can also hinder functional recovery. Currently, commonly used physical therapy methods include centripetal massage, limb elevation, circulatory pressure pump therapy, and cold or hot compresses. Circulatory pressure therapy uses a balloon to rhythmically inflate and deflate, mimicking the action of a muscle pump to promote venous and lymphatic return. Cold compresses can constrict blood vessels, reduce inflammation and pain; hot compresses can dilate blood vessels, promote metabolism, and relieve muscle tension.

[0003] However, existing treatment devices are often single-function, either being bulky, portable standalone air wave pressure therapy devices, or simple cold or hot compresses that require frequent manual changes and cannot be integrated with pressure therapy. Patients requiring alternating hot and cold compresses and pressure therapy need to prepare multiple devices, making operation cumbersome and resulting in low treatment compliance. Furthermore, existing hand pressure therapy devices are usually in the form of fixed gloves, making it difficult to accommodate both hands simultaneously, increasing usage costs and inconvenience. Summary of the Invention

[0010] Preferably, the airbag body is a multi-cavity airbag with divided areas, and the control module can independently control the inflation and deflation sequence and pressure of different cavities to achieve sequential pressurization from the distal end to the proximal end of the hand.

[0011] Preferably, the heating strip is a flexible electrothermal film, evenly distributed on the lower surface of the protective cover in the area corresponding to the hand.

[0012] Preferably, the protective cover is also equipped with a temperature sensor for monitoring the temperature of the heating area and feeding it back to the control module to achieve constant temperature control.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] This application provides a portable device for treating hand edema by combining circulatory pressure therapy and alternating hot and cold compresses. This device solves the problems in the prior art by highly integrating the circulatory pressure therapy module and the hot compress module into a compact structure composed of a protective frame and a protective cover. The overall size is small and easy for patients to carry, making it suitable for various scenarios such as home, travel, or office.

[0023] With its unique sliding protective cover design, users can adjust the cover's position on the protective frame according to whether the hand being treated is left or right, aligning the heating strip with the back of the hand and positioning the control screen in a direction that is easy to observe and operate. This achieves the device's versatility and reduces costs.

[0024] The touchscreen allows for flexible settings of parameters such as pressure mode, temperature, treatment time, and alternation cycle. The multi-chamber airbags simulate more physiological sequential compression. A hand-shaped placement base and flexible heating material enhance comfort. The addition of a temperature sensor ensures safe and constant-temperature application of the heat.

[0025] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example This embodiment provides the specific structure of a portable device for treating hand edema with circulatory pressure therapy and alternating hot and cold compresses, such as... Figure 1-5 As shown, the device includes a protective frame 1, the upper surface of which has a groove for accommodating the hand. The protective frame 1 is the basic support structure of the device, and its overall shape is rectangular. It is made of lightweight engineering plastic with appropriate strength. The upper surface of the protective frame 1 is recessed inward to form a groove for accommodating the user's hand. The contour of the groove is roughly adapted to the natural shape of the human hand, and a placement seat 5 is further provided at its bottom. The placement seat 5 is made of soft and elastic silicone material, and its surface contour is designed according to the physiological curvature of the hand, which can provide uniform and comfortable support for the wrist, palm and fingers, reducing local pressure during treatment. A protective cover 2 is slidably mounted in a groove above the protective frame 1. The protective cover 2 is a transparent acrylic sheet, slightly larger than the opening of the groove on the protective frame 1. The protective cover 2 is detachably mounted above the protective frame 1 via a sliding unit, precisely covering the groove. The sliding unit includes a pair of symmetrical grooves 7 formed on the two inner walls of the groove, and a pair of sliders 10 fixed to the two sides of the protective cover 2. The sliders 10 match the cross-section of the grooves 7, allowing the protective cover 2 to slide smoothly along the width of the groove. This design allows the user to flexibly adjust the coverage position of the protective cover 2 according to whether the treated hand is left or right, ensuring that the control module 3 is always positioned above the back of the hand for easy observation and operation, while simultaneously aligning the heating area with the back of the hand. The control module 3 is located on the upper surface of the protective cover 2, and is fixedly embedded in the central area of ​​the upper surface of the protective cover 2. It includes a color LCD screen and several physical buttons. Through the control module 3, users can intuitively set, adjust, and view various treatment parameters in real time, including but not limited to: pressure therapy modes (such as continuous pressure, pulse pressure, gradient pressure, etc.), target pressure values ​​(range 0-200 mmHg), single treatment duration (0-120 minutes), heat therapy temperature (range 30-50℃), and cycle time in alternating hot and cold therapy modes (such as 3 minutes of heat therapy, 5 minutes of pressure therapy, repeated). Control module 4 is located on the outer wall of protective frame 1 and is fixedly installed on one outer wall of protective frame 1. A touch screen 11 is integrated into the housing of control module 4 to display the device's operating status, current operating parameters, and operation menu. Control module 4 internally includes a main control circuit board, a pneumatic control solenoid valve, and an air pump body 12 located outside the protective frame 1 and connected to the airbag body 6 via a flexible conduit. Air pump body 12 is a miniature silent air pump responsible for generating compressed air. Control module 4 precisely controls the start and stop of air pump body 12 and the opening and closing of the solenoid valve according to a preset program, thereby regulating the pressure inside airbag body 6. The airbag body 6 is located inside the protective frame 1. The control module 4 is electrically connected to the airbag body 6 and is used to control the pressurization action of the airbag body 6. The airbag body 6 is located inside the protective frame 1, specifically below and around the placement seat 5. In this embodiment, the airbag body 6 adopts a multi-cavity structure with regional arrangements, specifically divided into four independent airbag cavities: corresponding to the finger area, metacarpophalangeal joint area, palm area, and wrist area, respectively. Each airbag cavity has an independent air path connected to the control module 4. The control module 4 can programmably control the inflation and deflation sequence of each airbag cavity and its respective pressure value. In a typical treatment sequence, the control module 4 controls the air pump body 12 to inflate and pressurize the airbag cavities sequentially from the distal end (finger) to the proximal end (wrist), and deflate them simultaneously or sequentially after a period of time, thereby simulating the "muscle pump" effect, promoting the centripetal return of venous blood and lymph in the hand, and realizing sequential pressurization therapy. Heating strips 9 are located on both sides below the protective cover 2 and are electrically connected to the control module 3. Heating strips 9 are flexible electric heating films, evenly distributed on the lower surface of the protective cover 2 corresponding to the area of ​​the hand. Heating is controlled by the control module 3. Heating strips 9 are adhered and fixed to the lower surface of the protective cover 2. Made of flexible electric heating film material, their shape is designed to be evenly distributed on the lower surface of the protective cover 2, corresponding to the main area of ​​the back of the hand, ensuring that the heat application area covers most of the back of the hand. Heating strips 9 are electrically connected to the control module 3 via wires passing through the protective cover 2. The control module 3 outputs control signals based on the temperature parameters set by the user. In addition, a temperature sensor (not separately labeled in the figure) is embedded on the lower surface of the protective cover 2 to monitor the temperature of the heating area in real time and feed the signal back to the control module 3. The control module 3 has a built-in PID control algorithm that dynamically adjusts the power of the heating strips 9 based on the difference between the set temperature and the feedback temperature to achieve constant temperature control and prevent the temperature from being too high or too low.

[0026] The cold compress box 13 is located in the center of the protective cover 2. The lower surface of the cold compress box 13 is also provided with a waterproof cloth 14. When a cold compress is needed, turn off the power of the heating strip 9, take out the ice pack, place the ice pack inside the cold compress box 13, and connect the protective cover 2 to the protective frame 1. In this way, the ice pack squeezes the waterproof cloth 14, and the waterproof cloth 14 comes into contact with the patient's hand, thereby achieving the effect of cold compress.

[0027] The protective cover 2 is detachably mounted on the protective frame 1 via a sliding unit, allowing the protective cover 2 to slide along the width of the groove to accommodate the placement posture of the left or right hand. The sliding unit includes a groove 7 disposed on the inner side wall of the groove in the protective frame 1, and sliders 10 disposed on both sides of the protective cover 2 and adapted to the groove 7. The control module 3 is used to set and display treatment parameters, including pressure treatment mode, pressure value, duration, hot compress temperature, and hot-cold alternation cycle.

[0028] The control module 4 includes an air pump body 12, which is located outside the protective frame 1 and connected to the airbag body 6 through a pipeline. The control module 4 controls the operation of the air pump body 12 to regulate the pressure inside the airbag body 6. It also includes a touchscreen 11 for displaying information.

[0029] The airbag body 6 is a multi-cavity airbag with divided areas. The control module 4 can independently control the inflation and deflation sequence and pressure of different cavities to achieve sequential pressurization from the distal end of the hand to the proximal end.

[0030] The protective cover 2 is also equipped with a temperature sensor to monitor the temperature of the heating area and feed it back to the control module 3 to achieve constant temperature control.

[0031] The protective frame 1 is also provided with a placement seat 5, the contour of which is adapted to the physiological curvature of the hand, so as to comfortably support the hand.

[0032] The control module 4 is connected to the control module 3. According to the program set by the control module 3, it coordinates and controls the cyclic pressure treatment of the airbag body 6 and the hot compress treatment of the heating strip 9, and alternates to work according to the preset cycle.

[0033] Work process and collaborative control: After the device is powered on, the user places the hand to be treated into the groove of the protective frame 1, with the wrist resting on the wrist support of the placement seat 5, and the palm naturally extended. Then, the user slides the protective cover 2 along the slide groove 7 to the left until it completely covers the back of the right hand. At this time, the control module 3 is located directly in front of the user's line of sight.

[0034] Users can select treatment modes and set parameters through the interface of control module 3. For example, they can select the alternating pressure and heat therapy mode, set the pressure value to 120 mmHg, the heat therapy temperature to 42℃, the pressure therapy duration to 5 minutes, the heat therapy duration to 3 minutes, and the total treatment time to 30 minutes.

[0035] After setup, the user initiates treatment. Control module 4 and operation module 3 communicate via internal wires (or wirelessly). Control module 4 coordinates the operation of the airbag body 6 and heating strip 9 according to received program instructions. The control module 4 first starts the air pump body 12, and according to the sequential pressurization logic, inflates the finger cavity, metacarpophalangeal joint cavity, palm cavity and wrist cavity of the airbag body 6 to 120 mmHg in sequence, and maintains this pressure for 5 minutes. During this period, the heating strip 9 does not work.

[0036] Five minutes later, control module 4 controls the solenoid valve to quickly expel the gas from the airbag body 6, releasing the pressure. At the same time, control module 3 controls the heating strip 9 to start working, achieving a constant temperature of 42℃ for 3 minutes through temperature sensor feedback.

[0037] When cold compress is needed, turn off the power to the heating strip 9, take out the ice pack, place the ice pack inside the cold compress box 13, and connect the protective cover 2 to the protective frame 1. In this way, the ice pack squeezes the waterproof cloth 14, and the waterproof cloth 14 comes into contact with the patient's hand, thereby achieving the effect of cold compress.

[0038] The above stages constitute a complete cycle. Control module 4 controls the device to cycle through 5 minutes of pressure therapy followed by 3 minutes of heat therapy until the total treatment time reaches 30 minutes, at which point it automatically stops and issues a prompt sound.

[0039] Throughout the treatment process, users can view information such as current pressure value, temperature, and remaining treatment time in real time through the touch screen 11 of the control module 3 or the control module 4, and can pause or adjust parameters when necessary.

[0040] This embodiment combines a sliding, adjustable protective cover 2, a multi-cavity airbag body 6 with zoned sequential pressurization, a temperature-controlled flexible heating film 9, and an intelligent integrated control module to provide a hand therapy device that effectively promotes blood circulation in the hand, eliminates edema, provides soothing heat therapy, is flexible to fit both left and right hands, and is intuitive and easy to operate. Its pressure and heat therapy can alternate according to a preset cycle, better meeting the diverse needs of clinical rehabilitation and home healthcare.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
