Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adsorption-type electrical stimulation device. Background Art

[0002] Adsorption-type electrical stimulation is a new biomedical technology that uses microelectrodes to be adsorbed onto nerve endings through the skin, improving the function of the nervous system through electrical stimulation. This technology has the advantages of minimal trauma, mild pain, and portability. It can be widely used in the treatment and rehabilitation of neurological disorders such as Parkinson's disease, stroke sequelae, spinal injuries, etc. In addition, adsorption-type electrical stimulation can also be used to control symptoms such as muscle tension, pain, nausea, etc., bringing patients a better quality of life.

[0003] Adsorption-type electrical stimulation uses an adsorption-type electrical stimulator, a medical device that uses low-frequency current to stimulate specific areas of the body for treatment, rehabilitation, and healthcare. Adsorption-type electrical stimulators combine the therapeutic benefits of neuromuscular electrical stimulation (NMES), transcutaneous neuromuscular electrical stimulation (TENS), and high-voltage electrotherapy (HVPC), and are based on the concepts of Traditional Chinese Medicine acupuncture and modern low-frequency electrotherapy. Adsorption-type electrical stimulators utilize adsorption electrodes that come into close contact with human skin, transmitting low-frequency current into the body to regulate bioelectrical activity, promote blood circulation, and alleviate pain. These devices typically feature a user-friendly design, with conical disc electrodes that accurately target the treatment area. The adsorption electrodes provide suction pressure, maintain stable adsorption pressure, and prevent dislodgement.

[0004] However, most of the existing adsorption-type electrical stimulators are trolley structures, which are large in size, inconvenient to move, and difficult to carry; they do not have an independent power supply and need to be connected to a power supply when in use, which is inconvenient to operate and cannot be used in an environment without power, and the use environment is easily restricted; they can only be connected to the adsorption module and cannot be connected to other modules, with a single function and poor versatility; patients need to frequently change instruments when they need multiple treatments, which is inconvenient to use, has low applicability, and a poor experience.

[0005] In summary, how to effectively solve the problems of the existing adsorption-type electrical stimulation device being inconvenient to use and having a poor user experience is an issue that currently needs to be urgently addressed by those skilled in the art. Utility Model Content

[0044] The core of the utility model is to provide an adsorption-type electrical stimulator, which can be connected to a variety of external modules, has multiple uses, can realize multiple uses and treatment functions, is easy to use, and has a good experience effect.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Please refer to Figures 1 to 15 In a specific embodiment, the adsorption-type electrical stimulator provided by the present invention includes a support plate 6, a battery 7 installed on the support plate 6, a circuit board 9, an air pump 11 and a water vapor separation box 12, a shell connected to the support plate 6, and a joint fixing plate 14 connected to the shell. The joint fixing plate 14 is connected to an electrical connection connector for connecting to a power module and an adsorption connector 15 for connecting to an adsorption module. The air pump 11 is connected to the adsorption connector 15 through the water vapor separation box 12, the battery 7 is electrically connected to the circuit board 9, and the circuit board 9 is electrically connected to the air pump 11 and the electrical connection connector. The shell is provided with an inclined receiving surface for placing an external module.

[0047] In the above structure, the adsorption-type electrical stimulator includes a support plate 6, a battery 7, a circuit board 9, an air pump 11, a water vapor separation box 12, a housing, and a joint fixing plate 14. The support plate 6 acts as a base, and the battery 7, circuit board 9, air pump 11, and water vapor separation box 12 are mounted on the support plate 6. The support plate 6 provides a support position for the internal components to ensure relative fixation between the components. The housing and support plate 6 cooperate to form a sealed space, fully protecting the internal components. The housing provides protection and can provide a buffer in the event of a collision, thereby improving the safety of the internal components.

[0048] Connector mounting plate 14 is attached to the housing. Electrical connectors and suction connectors 15 are connected to this mounting plate. Connectors for electrical modules such as electrode needles are connected to this mounting plate for acupuncture and other treatments. Connectors for suction modules such as suction bowls are connected to this suction connector 15 for suction therapy. The mounting plate provides a mounting location for the electrical connectors and suction connectors 15, ensuring stable installation and facilitating docking and use.

[0049] Battery 7 is electrically connected to circuit board 9 and provides power for the device, enabling it to operate without requiring a power source. Battery 7 also interacts with charging port 16. A power adapter is plugged into charging port 16 to charge battery 7, which is then unplugged after charging is complete. This device, equipped with battery 7, can be used independently of an external power source, expanding its scope of application.

[0050] Preferably, battery 7 is a polymer lithium battery, which is a lithium-ion battery that uses a solid polymer electrolyte instead of a liquid electrolyte. Compared to liquid lithium-ion batteries, polymer lithium batteries have higher energy density, lighter weight, better safety performance, and design flexibility, enabling ultra-thin and customizable shapes.

[0051] The air pump 11 is connected to the adsorption connector 15 through the water vapor separation box 12. The adsorption module connector is inserted into the adsorption connector 15, and the adjustment knob 17 is turned on. The air pump 11 starts working. The operating order of the internal air circuit is air pump 11-water vapor separation box 12-adsorption connector 15-adsorption module. The adsorption module works under the action of negative pressure. The movement path of the gas is caused by the air pump 11 sucking the gas from the adsorption bowl used into the adsorption connector 15, and then entering the water vapor separation box 12. After being controlled by the solenoid valve 10, the gas is extracted from the air pump 11. Optionally, the air pump 11 is provided with a muffler 24. The muffler 24 can not only effectively reduce noise, but also ensure that its resistance is small, avoiding a significant impact on the flow rate of the air pump 11.

[0052] The power module connector is inserted into the electrical connection connector, and the adjustment knob 17 is turned on. The battery 7 provides power to the power module, and the power module starts electroacupuncture and other operations, which has good versatility. It should be noted that the working principles and working processes of the adsorption module and the power module in this application are conventional technologies in the field and will not be further explained in this application.

[0053] The circuit board 9 is electrically connected to the air pump 11 and the electrical connector, and the operating state of the air pump 11 and the power supply state of the electrical connector are controlled by the circuit board 9. The power module and the adsorption module can operate independently or simultaneously, with multiple operating modes and comprehensive functions. When a patient undergoes multiple treatment methods such as acupuncture or adsorption, they can use a single device to complete the treatment, eliminating the need for frequent and repeated instrument changes. It is easy to use and has a good experience. It is also small and easy to carry.

[0054] At the same time, the shell is provided with an inclined receiving surface, and the external external module can be placed on the inclined receiving surface. The external module can be the above-mentioned adsorption module and adsorption module, or it can be a detection module, or even a mobile phone. The inclined receiving surface provides a placement platform for the external module, which is convenient for the staff to observe and operate the external module. The inclination angle of the inclined receiving surface can be between 25°-60°. If the external module placed is a display screen 19 or a touch screen, the bevel angle can be between 25°-60°. This angle range helps the operator to clearly view the desktop embedded bevel screen, while taking into account visual comfort and monitoring angles. If an operating device is placed, a 25-60 degree bevel angle is also applicable to adapt to different operating habits and visual requirements, and enhance the user experience.

[0055] Based on the above-mentioned specific embodiments, the shell includes a protective shell 1 and an upper cover 3 connected to the protective shell 1. The top surface of the protective shell 1 is a slope. The upper cover 3 includes an inclined supporting surface that is attached to the top surface of the protective shell 1 and a vertical upright surface connected to the lower end of the inclined supporting surface. The display screen 19 is arranged on the vertical upright surface, and the connector fixing plate 14 is arranged on the protective shell 1 and opposite to the display screen 19.

[0056] In one specific embodiment, the housing includes a protective shell 1 and an upper cover 3. The top surface of the protective shell 1 can be hollow or solid. The top surface of the protective shell 1 is a sloped surface with one end lower and the other higher. The upper cover 3 overlaps the top surface of the protective shell 1, and the two are closely connected. Therefore, the upper cover 3 has an inclined surface, and the external module is placed on the inclined surface to form an inclined receiving surface. This structure is simple and easy to form.

[0057] The vertical facade of the upper cover 3 is connected to the lower end of the inclined supporting surface. The display screen 19 and the circuit board connected to the display screen 19 are arranged on the vertical facade. The display screen 19 displays the real-time air pressure value, negative pressure adsorption value and electrical stimulation value. The display screen 19 faces the operator and the patient for easy viewing. The connector fixing plate 14 is arranged on the other side wall of the protective shell 1. The connector fixing plate 14 is opposite to the display screen 19. The adsorption connector 15 and the electrical connection connector are away from the operating side. It is not easy for the staff to collide with the connection connector of the adsorption module and the power connection module, ensuring that the adsorption module and the power connection module are reliably connected. The display screen 19 and the connector fixing plate 14 are installed on the side wall of the shell, with a compact structure, small size, and easy to carry.

[0058] Optionally, the protective shell 1 and the upper cover 3 can be connected by a middle cover 2. The corners of the middle cover 2 can be rounded to make the shape smoother and reduce scratches and bumps. The protective shell 1, the middle cover 2 and the upper cover 3 can be processed separately by injection molding, which is more convenient.

[0059] On the basis of the above-mentioned specific embodiments, the inclined supporting surface is provided with a support bracket at the lower end, the upper part of the inclined supporting surface is provided with a long hole along its inclination direction, the lower part of the inclined supporting surface is connected to a telescopic rod 5 at the long hole, and the upper part of the inclined supporting surface is provided with a clamping block 4, the lower part of the clamping block 4 passes through the long hole and is connected to the telescopic rod 5, and the upper part of the clamping block 4 and the support bracket constitute a movable clamping part for fixing the external module.

[0060] In a specific embodiment, the support bracket is a fixed part, the card block 4 is a movable part, and the telescopic rod 5 drives the card block 4 to move and position along the long hole. The movement of the card block 4 can also be adjusted by other card slot fixers such as the spring 23.

[0061] When the external module needs to be placed on the inclined receiving surface, the clamping block 4 is moved away from the support bracket, and the gap between the clamping block 4 and the support bracket is increased. When the gap is larger than the size of the external module, the back of the external module is placed on the inclined receiving surface, so that the bottom surface of the external module abuts the support bracket. The telescopic rod 5 is adjusted to move the clamping block 4 toward the support bracket until the clamping block 4 abuts the top surface of the external module. The clamping block 4 and the support bracket thus clamp and fix the external module to the inclined receiving surface, and the external module is firmly and reliably fixed. When the external module needs to be removed, the clamping block 4 is moved away from the support bracket to remove the external module, which is convenient to operate.

[0062] The clamping interval between the upper part of the clamping block 4 and the support bracket is adjustable, and external modules of different sizes can be installed and fixed. Different external modules can be replaced according to different usage requirements.

[0063] Based on the above-mentioned specific embodiments, the support bracket is an arc-shaped support angle arranged at the lower corner of the inclined supporting surface. The upper part of the block 4 includes a baffle perpendicular to the inclined supporting surface and a limit plate arranged on the upper edge of the baffle, and the limit plate is parallel to the inclined supporting surface.

[0064] In one specific embodiment, two right-angled curved support angles are provided at the lower corners of the inclined support surface to support the bottom surface of the external module and to limit the side surfaces of the external module. Preferably, the distance between the two curved support angles is equal to the width of the external module. The two curved support angles clamp the two sides of the external module to prevent the external module from shaking.

[0065] The upper portion of the clamping block 4 includes a baffle and a stopper. The baffle is perpendicular to the inclined receiving surface and presses against the top surface of the external module. The stopper is located at the upper edge of the baffle and is parallel to the inclined receiving surface. The upper portion of the clamping block 4 is inverted and concave. The upper end of the external module is inserted into the opening between the stopper and the bottom plate. The stopper limits the external module in a direction perpendicular to its surface, preventing it from bouncing or moving. Preferably, the distance between the stopper and the inclined receiving surface is equal to the thickness of the external module, further reducing bouncing and moving of the external module.

[0066] Based on the above-mentioned embodiments, the upper surface of the inclined receiving surface is provided with a groove 22 extending along its inclination. Groove 22 extends through the inclined receiving surface. The surface of groove 22 is lower than the surface of the inclined receiving surface. When an external module is placed on the inclined receiving surface, the module does not contact the inclined receiving surface at the groove 22. A gap is formed between the module and the surface of groove 22. Heat generated by the module dissipates through the gap and is discharged from both ends of the groove 22.

[0067] The groove 22 is provided on the inclined receiving surface, which facilitates cooling and heat dissipation of the external module and prolongs the service life of the external module.

[0068] Preferably, the upper surface of the inclined receiving surface is provided with grooves 22 in other directions, such as transverse grooves 22 perpendicular to the inclined direction, which are connected to the above grooves 22 to reduce the contact area between the inclined receiving surface and the external module and enhance heat dissipation.

[0069] Based on the above-mentioned specific embodiments, the upper cover 3 and the support plate 6 are connected by a connecting plate 18. The connecting plate 18 is provided with a lower connecting foot and an upper connecting foot. The lower connecting foot is parallel to the support plate 6, and the upper connecting foot has the same inclination angle as the inclined supporting surface. The connecting plate 18 is provided with a wire hole. The wires connecting the circuit board 9 and the circuit board pass through the wire hole. The wire path is short and the line is clear. The upper connecting foot and the lower connecting foot of the connecting plate 18 are parallel to the inclined supporting surface and the support plate 6 respectively, making it easy to connect the upper cover 3 and the support plate 6. The connecting plate 18 limits the connection angle of the inclined supporting surface to ensure the sealing of the connection between the upper cover 3 and the middle cover 2. The inclined supporting surface is not only supported on the middle cover 2, but also connected to the support plate 6. Its support point and angle are doubly restricted, making the connection more firm and reliable.

[0070] Based on the aforementioned specific embodiments, the circuit board 9 is connected to the top of the battery 7 via support columns, with a gap between the circuit board 9 and the top surface of the battery 7. The top surfaces of the support columns are aligned, meaning they are flush, and the circuit board 9 overlaps the top surfaces of the support columns. The mounting surface of the circuit board 9 is flat, ensuring a secure connection. Connection holes are provided on the top surfaces of the support columns and the circuit board 9, and the support columns and circuit board 9 are connected via bolts, making them easy to connect and disassemble.

[0071] On the basis of the above-mentioned specific embodiments, a protective shell 8 is provided on the circuit board 9. The protective shell 8 protects the circuit board 9, reduces the possibility of water intrusion and damage to the circuit board 9, and also has a protective buffering effect.

[0072] Based on the above specific embodiments, the air pump 11 is connected to the support plate 6 through the shock-absorbing column 21. The air pump 11 and the support plate 6 form an accommodating space between the shock-absorbing column 21, and a cooling fan 20 is installed in the accommodating space.

[0073] In a specific embodiment, components such as the air pump 11 are heat-generating parts that need to dissipate heat during operation. Heat dissipation holes and a heat dissipation fan 20 are provided on the support plate 6 for heat dissipation. In order to reduce the vibration of the air pump 11, a shock-absorbing column 21 is connected to the support plate 6, and the air pump 11 is installed on the shock-absorbing column 21. The air pump 11 and the support plate 6 form a storage space between the shock-absorbing column 21, and the heat dissipation fan 20 can be installed in the storage space. By utilizing the internal cavity, the structure is compact, the volume is reduced, and it is more compact and easy to carry. In order to shorten the heat discharge path, a heat dissipation hole is provided at the position of the heat dissipation fan 20 on the support plate 6, and the heat generated by the air pump 11 is discharged directly from the heat dissipation hole through the heat dissipation fan 20, thereby improving the heat dissipation efficiency.

[0074] Preferably, the connector fixing plate 14 is provided with heat dissipation holes to increase the heat dissipation area and improve the heat dissipation efficiency.

[0075] On the basis of the above-mentioned specific embodiments, a liquid discharge control mechanism is further included. A liquid discharge port is provided on the water vapor separation box 12. The liquid discharge control mechanism includes:

[0076] A liquid level sensor connected to the circuit board 9 for detecting the liquid height in the water vapor separation box 12;

[0077] A drainer 13 is connected to the liquid level sensor and the circuit board 9 and is used to control the opening of the drain port when the current liquid level of the water vapor separation box 12 is greater than the limit liquid level.

[0078] In actual application, a liquid level detector is provided in the water vapor separation box 12. When the water inside the water vapor separation box 12 reaches the limit liquid level height, the drainage control mechanism can send an electrical signal to remind the user, and then the excess water in the water vapor separation box 12 can be discharged with the help of the drainer 13.

[0079] In a preferred embodiment, the drainer 13 is a control valve. When the control valve receives a signal indicating that the water inside the water vapor separation box 12 has reached a limit liquid level, the control valve automatically opens to discharge excess water in the water vapor separation box 12 to the outside, thereby realizing automatic control.

[0080] Based on the above specific embodiments, an air pressure control mechanism is further included, and the air pressure control mechanism includes:

[0081] A pressure sensor connected to the circuit board 9 for detecting the gas pressure in the water vapor separation box 12;

[0082] An air pressure control unit connected to the circuit board 9 for controlling the operating position of the air pump 11.

[0083] In actual application, a pressure sensor connected to the water vapor separation box 12 is provided on the circuit board 9. The pressure sensor transmits the signal to the circuit board 9, and the circuit board 9 transmits the signal to the display circuit board. The solenoid valve 10 is connected to the signal of the circuit board 9. The circuit board 9 outputs a signal to control the operation of the solenoid valve 10, and adjusts the working state of the solenoid valve 10 to control the air pump 11 to adsorb in an intermittent mode, and then the water sucked out by the adsorption joint 15 enters the water vapor separation box 12, and then the water vapor is separated.

[0084] The solenoid valve 10 controls the air pump 11 to achieve an intermittent mode of adsorption, which can be achieved by programming the switching state of the solenoid valve 10. Specifically, the adsorption and release of the air pump 11 can be controlled by setting a specific time interval and duration to achieve an intermittent working mode. For example, the air pump 11 has multiple working gears. The air pump 11 can be set to work for a period of time so that the air pressure value in the water vapor separation box 12 reaches a first preset value and then stops. Then, after waiting for a set time, the air pump 11 works again for a period of time so that the air pressure value in the water vapor separation box 12 reaches a second preset value and then stops. After the working gears of the air pump 11 are completed in the set order, it enters the circulation mode. According to the needs of actual applications, it may be necessary to optimize and adjust the control logic to ensure that the intermittent adsorption mode of the air pump 11 meets specific working requirements. Using the solenoid valve 10 to control the air pump 11 to achieve the required intermittent adsorption mode meets the needs of automated control and ensures stable operation under various working conditions.

[0085] The adsorption-type electrical stimulation device provided by the present invention has a compact structure, a small size and is easy to carry; it is equipped with a battery 7 and can be used without an external power supply, so the use environment is not restricted and the scope of application is expanded; it has multiple treatment modes such as electroacupuncture and adsorption, is provided with an inclined receiving surface for placing external modules, and has an automatic drainage control mode and an intermittent adsorption automatic control mode. It has complete functions, and when patients undergo acupuncture or adsorption and other treatment methods, they can use one device to complete the treatment, without the need to frequently and repeatedly change the device.
