Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable electrotherapy device. Background Technology

[0002] Interferential current therapy (ICP) is a medical device that uses intermediate-frequency currents of different wavelengths to cross-input the human body, creating interference at the intersection of electric field lines, thereby generating low-frequency modulated pulse currents in deep tissues. Through clinical application, this device can achieve various therapeutic effects, including pain relief, analgesia, anti-inflammation, promoting blood circulation, regulating autonomic nerve function, activating tissue cells, exercising motor nerves and skeletal muscles, increasing the tension of visceral smooth muscle, treating muscle atrophy, and promoting fracture healing.

[0003] In existing technologies, the electrodes of interferential current therapy devices are typically fixed to the patient's affected area using a combination of an absorbent sponge and a vacuum chamber. While the sponge becomes conductive after absorbing water, it also acts as an adsorption head, using a negative pressure device to draw air out of the vacuum chamber to achieve adsorption and fixation.

[0004] However, existing fixation methods have several problems during use: First, the absorbent sponge easily draws water into the gas canister during the conductive process. Water entering the gas canister affects its negative pressure adsorption function, leading to poor negative pressure effects during subsequent use, and even water overflow, thus affecting the electrode fixation effect and the stability of the treatment. These defects in the fixation method seriously affect the effectiveness and reliability of the electrotherapy device.

[0005] In summary, how to effectively solve the problems of water entering the gas tank and poor negative pressure adsorption effect in existing interferential electrotherapy devices in terms of electrode fixation is an urgent problem that needs to be solved by those skilled in the art.

Detailed Implementation

[0040] The core of this utility model is to provide a portable electrotherapy device, which effectively solves the problems of water entering the gas tank and poor negative pressure adsorption effect in the electrode fixing method of existing interference electrotherapy devices.

[0041] 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.

[0042] Portable electrotherapy devices are multi-functional medical equipment that provides efficient and convenient electrotherapy services while addressing issues such as fluid reflux and poor negative pressure adsorption in traditional devices. Please refer to [link / reference]. Figures 1 to 8 This is a schematic diagram of the structure of a portable electrotherapy device provided in a specific embodiment of this utility model.

[0043] In one specific embodiment, the portable electrotherapy device provided by this utility model includes a housing 1, a negative pressure pump 3 installed in the housing 1, a gas tank 5 connected to the negative pressure pump 3 via a first interface, a three-way device 8 connected to the second interface of the gas tank 5 via a first port, an electrotherapy socket 6 connected to the second port of the three-way device 8 for connecting an adsorption component, and a water collection tank 7 connected to the third port of the three-way device 8. The water collection tank 7 has a drain outlet, and the third port is located below the first and second ports. It also includes a one-way valve 11 connected between the third port of the three-way device 8 and the inlet of the water collection tank 7 to prevent the backflow of liquid in the water collection tank 7.

[0044] In the above structure, the housing 1 has a storage space inside to store the external adsorption components, preventing them from being lost or damaged when not in use. The housing 1 is equipped with multiple electrotherapy sockets 6, which are connected to an electrotherapy circuit board via wiring to ensure stable transmission of electrotherapy signals to the adsorption components. It is typically made of robust materials, such as engineering plastics or metal alloys, to ensure the device's durability and portability.

[0045] A cover 2 is located at the upper opening of the housing 1. The housing 1 and cover 2 are connected by a support rod, which supports cover 2 when it is open. Cover 2 integrates an electrotherapy circuit board, a battery, and a cooling fan. The electrotherapy circuit board is the control component, used to process and transmit the electrical signals required for electrotherapy. The circuit board, in conjunction with the battery, provides a stable power supply to the entire device, ensuring its independence and flexibility during portable use. The cooling fan dissipates heat from the interior of the housing 1 and cover 2, ensuring that the electrical components operate within a safe temperature range, thus guaranteeing stable operation of the device. The cooling fan can be electrically connected to the electrotherapy circuit board via wiring, and its operation is controlled by the circuit board. A display screen is mounted on the surface of cover 2 to show the device's operating status, battery level, treatment parameters, and other information, providing the user with an intuitive operating experience.

[0046] The negative pressure pump 3 is installed inside the housing 1. It generates negative pressure to achieve the adsorption function, ensuring that the adsorption components are firmly fixed to the patient's skin. The gas cylinder 5 is connected to the negative pressure pump 3 through the first interface for pressure maintenance. The gas cylinder 5 has sufficient capacity to meet treatment needs and ensures a stable supply of negative pressure. The material of the gas cylinder 5 has good sealing and pressure resistance, ensuring safe and reliable use.

[0047] The housing 1 is equipped with multiple electrotherapy sockets 6, which are connected to the second interface of the air tank 5. The sockets 6 are connected to the adsorption component, transmitting negative pressure to the adsorption component. A water-soaked sponge is placed inside the adsorption component to improve conductivity. The adsorption component includes an adsorption bowl, which achieves negative pressure adsorption and fixation through the negative pressure pump 3 and the air tank 5.

[0048] The third port of gas tank 5 is connected to the exhaust valve, which is controlled by a solenoid valve to release gas after the equipment is used. The fourth port of gas tank 5 is connected to a pressure sensor to detect the gas pressure in gas tank 5.

[0049] A three-way device 8 is connected between the electrotherapy socket 6 and the second interface of the gas tank 5. The three-way device 8 has three interfaces: the first interface is connected to the second interface of the gas tank 5 to receive negative pressure; the second interface is connected to the electrotherapy socket 6, specifically to the connecting pipe 15 of the electrotherapy socket 6, to transmit negative pressure to the adsorption component; the third interface is located below the first and second interfaces and is used to drain liquid and prevent liquid from entering the gas tank 5.

[0050] The water collection tank 7 is connected to the third port of the three-way device 8 to collect and store the liquid flowing in from the adsorption component. The water collection tank 7 has a drain outlet for easy drainage of accumulated water. The capacity of the water collection tank 7 is sufficient to effectively collect and treat the liquid, preventing backflow into the gas tank 5. A one-way valve 11 is connected between the third port of the three-way device 8 and the liquid inlet of the water collection tank 7 to prevent backflow of liquid from the water collection tank 7, ensuring that the liquid can only flow in one direction, thereby preventing liquid from flowing back into the gas tank 5 and affecting the negative pressure adsorption effect.

[0051] During use, the negative pressure pump 3 is connected to the first interface of the gas tank 5 to generate negative pressure. This negative pressure is transmitted through the second interface of the gas tank 5 to the first port of the three-way device 8, then through the second port of the three-way device 8 to the electrotherapy socket 6, and finally to the adsorption component. The adsorption component is firmly fixed to the patient's skin by the negative pressure. During use, a water-soaked sponge is placed inside the adsorption bowl to reduce resistance and enhance conductivity. The liquid in the adsorption component travels through the adsorption bowl along the connecting pipe 15 to the three-way device 8. Under its own weight, the liquid flows through the third port of the three-way device 8 and into the water collection tank 7 via the one-way valve 11. Gas enters the gas tank 5 through the first port of the three-way device 8, completing the negative pressure adsorption process and simultaneously achieving air intake and drainage, preventing liquid from entering the gas tank 5 and affecting subsequent use. The electrotherapy socket 6 is connected to the electrotherapy circuit board via wiring to ensure stable transmission of the electrotherapy signal to the adsorption component, thus realizing the treatment function.

[0052] The portable electrotherapy device provided by this utility model recovers and treats the liquid that overflows during the negative pressure adsorption process through the water collection tank 7 and the one-way valve 11, solving the problem of liquid backflow and preventing water from overflowing into the gas tank 5 and affecting the subsequent negative pressure adsorption effect of the gas tank 5. This ensures the stability and reliability of the adsorption effect, not only extending the service life of the device but also improving the safety of the treatment process. At the same time, it is convenient to use, easy to carry and transfer, and has a wide range of applications.

[0053] Based on the above specific embodiments, the three-way device 8 includes a vertically placed U-shaped tube, with connection ports on the upper ends and bottom surfaces of both sides of the U-shaped tube, wherein the connection ports on both sides serve as the first port and the second port, and the connection port on the bottom surface serves as the third port.

[0054] In one specific embodiment, the U-shaped tube is placed vertically with its axis aligned vertically, resulting in a compact structure that effectively utilizes space while ensuring smooth flow of liquids and gases. The U-shaped tube is bifurcated, with connection ports on both its upper and lower sides for different functions, ensuring efficient management and transmission of negative pressure and liquids. Specifically, the first port is located at the upper end of one side of the U-shaped tube and connects to the second interface of the gas cylinder 5 via a connecting pipe 15. Its main function is to receive negative pressure from the gas cylinder 5, ensuring stable transmission of negative pressure to subsequent components. The second port is located at the upper end of the other side of the U-shaped tube and connects to the electrotherapy socket 6 via a connecting pipe 15. Its main function is to transmit negative pressure to the adsorption component, ensuring that the adsorption component is firmly fixed to the patient's skin. The third port, located at the bottom of the U-shaped tube, is used to drain liquid. Its main function is to prevent liquid from entering the gas cylinder 5, ensuring that the negative pressure system within the gas cylinder 5 is not disturbed by liquid, thereby maintaining a stable supply of negative pressure.

[0055] During operation, negative pressure is transmitted through the second port of the gas tank 5 to the first port of the three-way device 8. The negative pressure then travels through a U-shaped tube to the second port, and further to the electrotherapy socket 6, ultimately reaching the adsorption component. Under negative pressure, the liquid within the adsorption component flows through the adsorption bowl along the connecting pipe 15 to the three-way device 8. Under its own gravity, the liquid enters the water collection tank 7 through the third port, while the gas returns to the gas tank 5 through the first port. This design effectively separates the liquid and gas, preventing liquid backflow into the gas tank 5 and ensuring the stable operation of the negative pressure system.

[0056] Based on the above specific embodiments, a vertical pipe is connected to the end of the connector, the three ports of the tee device 8 are located at the end of the vertical pipe, and the inner diameter of the U-shaped pipe is larger than the inner diameter of the vertical pipe.

[0057] In one specific embodiment, each connection port is connected to a vertical pipe at its end, and the three ports of the tee device 8 are located at the ends of these vertical pipes. The vertical pipes facilitate the connection of the tee device 8 to the water tank 7, the gas tank 5, and the pipe 15 of the electrotherapy socket 6. This connection method not only simplifies the installation process but also reduces the risk of leakage due to improper connection, ensuring the sealing and functionality of the equipment.

[0058] The inner diameter of the U-shaped tube is larger than that of the vertical tube, reaching 8mm. This larger inner diameter allows for smoother fluid flow within the U-shaped tube, effectively reducing turbulence. Therefore, gas and liquid can separate more smoothly without interference, resulting in better gas-liquid separation. During the negative pressure adsorption process, the liquid, under its own gravity, smoothly exits the device through the vertical tube; simultaneously, the gas returns to the gas tank 5 along the U-shaped tube. This simultaneous drainage during negative pressure adsorption not only improves the efficiency of the adsorption process but also prevents liquid from accidentally entering the gas tank 5, thus completely resolving the issue of liquid entering the gas tank 5 and affecting subsequent use.

[0059] Based on the above specific embodiments, the vertical pipe where the first opening is located is connected to the second interface of the water collection tank 7 through a horizontal pipe, and a valve is provided inside the horizontal pipe.

[0060] In one specific embodiment, the vertical pipe containing the first inlet is connected to the second interface of the water collection tank 7 via a horizontal pipe. A bend is formed between the vertical and horizontal pipes, further preventing liquid from entering the gas tank 5. A valve is installed inside the horizontal pipe, its main function being to achieve unidirectional control of fluid flow. Specifically, the valve ensures that liquid can only flow from the three-way device 8 to the water collection tank 7 and cannot flow in the opposite direction, thus preventing a small amount of liquid from accidentally entering the gas tank 5 when the suction is too strong.

[0061] During the negative pressure adsorption process, under the action of negative pressure, even if a small amount of liquid in the adsorption component reaches the first port of the three-way device 8 through the adsorption bowl along the connecting pipe 15, it will still flow into the water collection tank 7 under the guidance of the valve when it reaches the valve. The one-way control function of the valve prevents liquid backflow, thereby avoiding liquid backflow into the gas tank 5 and ensuring the stable operation of the negative pressure system.

[0062] Based on the above specific embodiments, it also includes:

[0063] A drain pump 9 is connected to the drain outlet of the water collection tank 7 to drain the liquid inside the water collection tank 7;

[0064] A high liquid level sensor 17 is installed inside the water collection tank 7 to detect whether the liquid level inside the water collection tank 7 has reached the high liquid level.

[0065] A drain controller connected to a drain pump 9 and a high liquid level sensor 17, used to control the drain pump 9 to operate and drain the liquid in the collection tank 7 when the high liquid level sensor 17 detects that the liquid level has reached a high level.

[0066] In one specific embodiment, a drain pump 9 is connected to the drain outlet of a water collection tank 7 to drain the liquid inside the tank. When the liquid in the water collection tank 7 accumulates to a certain level, the drain pump 9 will start to drain the liquid, preventing the tank from overflowing due to excessive liquid and thus ensuring the normal operation of the equipment. The operation of the drain pump 9 is intermittent; it starts and stops automatically based on the accumulation of liquid in the water collection tank 7.

[0067] A high-level sensor 17 is installed inside the water collection tank 7 to detect whether the liquid level has reached the high level. When the liquid level reaches the set high level, the sensor will send a signal to notify the drain controller to take appropriate measures. The high-level sensor 17 determines whether the liquid level has reached the high level by detecting the height of the liquid in the water collection tank 7. Once the liquid level reaches the high level, the sensor will trigger a signal to notify the drain controller.

[0068] Upon receiving a signal from the high-level sensor 17, the drain controller activates the drain pump 9 to drain the liquid from the collection tank 7. The controller adjusts the operation of the drain pump 9 based on the signal from the high-level sensor 17. When a high-level signal is received, the controller starts the drain pump 9 to drain the liquid from the collection tank 7. Once the liquid level drops to a safe level, the controller can choose to stop the drain pump 9 or continue draining until the collection tank 7 is completely emptied.

[0069] In the above embodiments, the portable electrotherapy device is equipped with an automated drainage system, which can automatically manage the liquid level in the water collection tank 7, prevent excessive liquid from causing malfunctions, improve equipment reliability and maintenance convenience, reduce manual intervention, and ensure the continuity and stability of the treatment process.

[0070] Based on the above specific embodiments, it also includes:

[0071] A low-level sensor installed inside the water collection tank 7 to detect whether the liquid level inside the water collection tank 7 has reached the low level;

[0072] A drain button is connected to the drain pump 9, the low liquid level sensor, and the high liquid level sensor 17, and is used to manually trigger the drain pump 9 to start draining when the liquid level is between the low liquid level and the high liquid level.

[0073] In practical applications, a low-level sensor is installed inside the water collection tank 7 to detect whether the liquid level has reached the set low level. When the liquid level reaches the low level, the sensor triggers a signal. The low-level sensor and the high-level sensor 17 determine the liquid level status by detecting the height of the liquid in the water collection tank 7. Various detection methods are used, including float-type, pressure-type, and ultrasonic-type methods.

[0074] The drain button is connected to the drain pump 9 and the low-level and high-level sensors 17. The sensors send liquid level information to the drain button. When the liquid level is between the low and high levels, the user can manually trigger the drain button to start the drain pump 9 to drain the liquid. After draining is complete, the user can press the button again to stop the drain pump 9 from operating.

[0075] In the above embodiment, the drain controller automatically adjusts the operation of the drain pump 9 based on sensor signals, while the drain button provides users with the flexibility to manually operate the drain pump 9. This design improves the automation level of the equipment, enhances ease of use and user control, and ensures stable operation of the equipment in different situations.

[0076] Based on the above specific embodiments, it also includes:

[0077] Tilt sensor 4 is used to detect whether housing 1 is tilted;

[0078] An alarm connected to tilt sensor 4, used to issue an alarm signal when tilt sensor 4 detects that housing 1 is not placed flat.

[0079] In practical applications, the tilt sensor 4 installed inside the housing 1 can monitor the placement angle of the equipment in real time, ensuring it remains horizontal during operation. This step is crucial because only when the equipment is horizontal can the level sensor accurately measure the liquid level in the collection tank 7, allowing for timely liquid discharge and ensuring stable equipment operation. The tilt sensor 4 can accurately detect the tilt angle of the housing 1 using built-in components such as an accelerometer or gyroscope. When the tilt angle of the housing 1 exceeds a preset safety threshold, the sensor triggers a signal to notify the alarm.

[0080] Upon receiving the trigger signal from the tilt sensor 4, the alarm will immediately emit an audible and visual alarm to remind the user that the equipment is not placed level, and to promptly adjust the position or angle of the housing 1 to ensure it is level. This alarm mechanism effectively prevents inaccurate detection by the liquid level sensor due to equipment tilt, thus avoiding liquid overflow. The alarm can employ multiple alarm methods, including audible alarms from a buzzer, flashing LED alarms, or a combination of both, to enhance the visibility and reliability of the alarm, ensuring that the user can promptly notice and adjust the placement of the equipment.

[0081] In the above embodiment, the tilt sensor 4 monitors the placement status of the equipment in real time. If the equipment is not placed level, the user will be promptly reminded to adjust it. This ensures that the equipment is in a level position during operation, enabling the liquid level sensor to accurately detect the liquid level and promptly drain the liquid from the collection tank 7, thus ensuring stable operation of the equipment.

[0082] Based on the above specific embodiments, the housing 1 includes a storage cavity and an installation cavity. The installation cavity is divided into an upper region and a lower region by a partition plate. The gas tank 5 is located at the first end of the lower region. There is a gap between the gas tank 5 and the side wall of the housing 1. The area from the second end of the lower region to the gas tank 5 is divided into an upper installation space and a lower installation space by an installation plate 12. The negative pressure pump 3 is installed in the upper installation space, the water collection tank 7 and the drain pump 9 are installed in the lower installation space, and the electrotherapy socket 6, the three-way device 8 and the one-way valve 11 are installed in the gap.

[0083] In one specific embodiment, the internal space of the housing 1 of the portable electrotherapy device is divided into a storage cavity and a mounting cavity by a vertical partition. The storage cavity, located on one side of the housing 1, is used to store external adsorption components, ensuring that these components can be safely stored when not in use, preventing loss or damage. The mounting cavity, located on the other side of the housing 1, centrally houses the functional components required for the operation of the device. This layout not only improves the integration of the device but also optimizes space utilization, ensuring that the components are rationally arranged and operate efficiently.

[0084] The mounting cavity is further divided into an upper and lower area by a horizontally arranged partition. The upper area has an outlet for the electrotherapy socket 6 and a water tank for easy user operation. The lower area houses components that are not frequently operated or disassembled, such as the negative pressure pump 3, air tank 5, drain pump 9, and water collection tank 7.

[0085] Because of its height, the gas cylinder 5 is installed at the first end of the lower section of the mounting cavity, occupying the entire height space of the lower section. Meanwhile, a gap is reserved between the gas cylinder 5 and the side wall of the housing 1, where narrow components such as the electrotherapy socket 6, the three-way device 8, the one-way valve 11, and the connecting pipe 15 are installed. This layout not only saves space but also facilitates maintenance and component replacement.

[0086] In the lower section of the mounting cavity, from the second end to the gas tank 5, the area is further divided into an upper mounting space and a lower mounting space by the mounting plate 12. The negative pressure pump 3 is installed in the upper mounting space to generate negative pressure for adsorption; while the water collection tank 7 and drain pump 9 are installed in the lower mounting space to collect and drain liquid, ensuring that the equipment does not malfunction due to liquid accumulation during operation. This layered layout helps to rationally arrange components with different functions, reducing mutual interference and thus improving the stability and reliability of the equipment. At the same time, the compact structural design makes the equipment small in size and easy to carry.

[0087] Based on the above specific embodiments, a water box connected to the outlet of the drain pump 9 is also included. The water box is located in the upper area. The upper area of ​​the housing 1 is provided with two quick plugs that are respectively connected to the water box and the outlet of the drain pump 9. The two quick plugs are connected to the hoses.

[0088] In one specific embodiment, the water box is connected to the outlet of the drain pump 9 and is mainly used to collect the liquid discharged by the drain pump 9. When it is inconvenient to directly discharge the liquid, the water box can temporarily store the liquid. The water box is located in the upper area of ​​the housing 1 and is detachably connected to the housing 1. Specifically, it can be placed directly on the bottom plate of the upper area, or magnets can be provided on the contact surfaces of the bottom plate and the water box for magnetic connection. This magnetic connection not only improves the stability of the connection but also makes the disassembly of the water box convenient and quick. When there is too much liquid in the water box, the user can manually remove the water box and pour out the liquid. The water box is located on the surface of the housing 1 for easy access.

[0089] The upper part of the housing 1 is equipped with two quick-connect plugs, which connect to the water tank and the outlet of the drain pump 9, respectively. These two quick-connect plugs are connected via flexible hoses, facilitating installation and disassembly and improving the portability and ease of use of the device. Preferably, the water tank is made of a transparent material, allowing users to visually observe the liquid level inside and empty it promptly to prevent overflow.

[0090] Based on the above specific embodiments, a damping plate 13 is also included. The sides of the damping plate 13 and the mounting plate 12 are provided with matching arc-shaped slots 16, and the two ends of the damping column 14 are respectively connected to the arc-shaped slots 16 of the damping plate 13 and the mounting plate 12.

[0091] In one specific embodiment, the damping plate 13 is used to reduce the vibration generated during the operation of the negative pressure pump 3, improving the user experience of the equipment. The damping plate 13 and the mounting plate 12 are parallel and have a set distance between them. The damping column 14 can effectively absorb and disperse the vibration generated during the operation of the equipment, ensuring that the equipment remains stable during operation. The mounting plate 12 and the side of the damping plate 13 have openings in the arc-shaped slot 16. The two ends of the damping column 14 are respectively inserted into the openings and slide into the arc-shaped slot 16 and are locked at the end of the arc-shaped slot 16. When disassembling, the damping column 14 is slid out of the arc-shaped slot 16 in the opposite direction. The connection and disassembly operation is convenient through the sliding connection and disassembly method of the damping column 14 with the damping plate 13 and the mounting plate 12.

[0092] The vibration damping plate 13 is used to reduce the vibration generated during the operation of the negative pressure pump 3, thereby improving the user experience. The vibration damping plate 13 is parallel to the mounting plate 12, and a certain distance is maintained between them. The vibration damping column 14 can effectively absorb and disperse the vibration generated during the operation of the equipment, ensuring that the equipment remains stable during operation.

[0093] The mounting plate 12 and the damping plate 13 have arc-shaped slots 16 on their sides, with openings. The two ends of the damping column 14 are respectively inserted into the openings and slide into the arc-shaped slots 16, eventually locking at the ends of the slots. For disassembly, simply slide the damping column 14 out of the arc-shaped slots 16 in the opposite direction. This design creates a stable sliding connection between the damping column 14, the damping plate 13, and the mounting plate 12. This sliding connection and disassembly method facilitates the installation and removal of the damping column 14, further improving the ease of equipment maintenance.

[0094] In one specific embodiment, the portable electrotherapy device is also equipped with a silencer 10, installed in the lower mounting space. The first end of the silencer 10 is open to the atmosphere, used to discharge excess gas generated by the negative pressure pump 3 and gas discharged from the gas tank 5. The first connection end is connected to the air inlet of the negative pressure pump 3, and the second connection end is connected to the third interface of the gas tank 5 via a solenoid valve. After the device is used, the solenoid valve is opened to discharge the gas from the gas tank 5. The silencer 10 effectively reduces noise during the operation of the negative pressure pump 3 and the discharge of gas, ensuring that the device remains quiet during operation and providing a more comfortable user experience.

[0095] To simplify the structure, the second connection end can be connected to the connection port of the electrotherapy socket 6 via a T-shaped elbow, and the other end of the T-shaped elbow can be connected to the second end of the T-shaped device.
