Description

Technical Field

[0001] This utility model relates to the field of electrostimulation therapy technology, and in particular to an electrotherapy adsorption bowl. Background Technology

[0002] Electrical stimulation therapy involves attaching electrode pads to the skin surface at specific locations on the body. These electrodes then apply electrical stimulation signals to the body's tissues, thereby stimulating various muscles and nerves. This technique aims to delay muscle atrophy caused by disuse in hemiplegic patients, reduce inflammation, and promote physical recovery.

[0003] To fix the electrode pads to the skin, a vacuum adsorption bowl is often used. The electrode pads are placed inside the bowl, and a conductive circuit connects the electrode pads to a power supply. A vacuum is then created inside the bowl, allowing it and the electrode pads to adhere to the skin. The power supply then provides electrical stimulation signals to the electrode pads, thus enabling electrostimulation therapy. However, in practical applications, the conductive circuits are prone to rusting and breakage, which reduces the lifespan of the treatment equipment used for electrostimulation therapy. Utility Model Content

[0004] The purpose of this invention is to provide an electrotherapy adsorption bowl that can, to a certain extent, avoid the problem of conductive wires rusting and breaking due to corrosion caused by sweat and other substances, thereby extending the service life of the electrotherapy adsorption bowl.

[0005] To solve the above-mentioned technical problems, this utility model provides an electrotherapy adsorption bowl, including a bowl structure; a metal electrode disposed inside the bowl structure; and a channel portion disposed at the bottom of the bowl structure, wherein the channel portion has a first channel and a second channel that are isolated from each other; wherein, a conductive wire is disposed in the first channel, one end of which is electrically connected to the metal electrode and the other end of which is electrically connected to a power supply; one end of the second channel is in air communication with the inside of the bowl structure, and the other end of which is in air communication with a negative pressure pump.

[0006] In one optional embodiment of this application, the section of the first channel near the metal electrode is a vertical section parallel to the central axis of the bowl structure; a piston is disposed within the vertical section; the piston and the metal electrode are fixedly connected.

[0007] When the negative pressure pump draws air from the bowl structure through the second channel, causing the air pressure in the channel section of the first channel located on the side of the piston away from the metal electrode to be greater than the air pressure inside the bowl structure, the piston drives the metal electrode to move towards the bowl opening of the bowl structure.

[0008] In one alternative embodiment of this application, the port on the side of the first channel opposite to the metal electrode is in communication with the external environment.

[0009] In one optional embodiment of this application, the port of the first channel opposite to the metal electrode and the outlet of the negative pressure pump are connected by a gas supply pipe.

[0010] A battery valve is installed between the gas supply pipe and the outlet of the negative pressure pump.

[0011] In one optional embodiment of this application, a drying filter screen is also provided inside the gas pipeline.

[0012] In one optional embodiment of this application, the first channel is an L-shaped channel formed by the vertical segment and the horizontal segment;

[0013] A telescopic spring is also provided in the first channel. One end of the telescopic spring is fixedly connected to the surface of the piston away from the metal electrode, and the other end is fixedly connected to the inner wall of the corner section of the L-shaped channel.

[0014] In one optional embodiment of this application, the telescopic spring is a conductive spring, and the telescopic spring shown is at least a portion of the conductive wire.

[0015] In one optional embodiment of this application, a limiting structure is provided at the end of the first channel near the metal electrode, and the limiting structure forms a port with an aperture smaller than the piston diameter at the end of the first channel near the metal electrode.

[0016] In one optional embodiment of this application, a sealing ring is provided on the outer surface of the piston.

[0017] In one optional embodiment of this application, the bowl structure is a rigid bowl; a rubber ring is provided on the rim of the bowl structure.

[0018] The present invention provides an electrotherapy adsorption bowl, comprising a bowl structure; a metal electrode disposed inside the bowl structure; and a channel portion disposed at the bottom of the bowl structure, wherein the channel portion has a first channel and a second channel that are isolated from each other; wherein, a conductive wire is disposed in the first channel, one end of which is electrically connected to the metal electrode and the other end of which is electrically connected to a power supply; one end of the second channel is connected to the air inside the bowl structure, and the other end of the second channel is connected to the air of a negative pressure pump.

[0019] In this application, the bottom of the bowl structure has two isolated channels, a first channel and a second channel, which are respectively used to accommodate the conductive wire and to act as an airflow channel for evacuating air from the bowl structure. Thus, when the negative pressure pump evacuates air from the bowl structure through the second channel, sweat and other substances produced on the surface of human skin will only enter the second channel and will not enter the first channel where the conductive wire is located. This avoids the problem of the conductive wire rusting and breaking due to corrosion caused by sweat and other substances, thereby improving the service life of the electrotherapy adsorption bowl.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0023] It is understandable that when the electrotherapy adsorption bowl is attached to the surface of human skin, the area of ​​human skin to which the adsorption bowl is attached will inevitably have sweat or other stains. As the negative pressure pump draws air from the bowl structure through the airflow channel, sweat and other stains will inevitably enter the airflow channel. In traditional electrotherapy adsorption bowls, the conductive wires are often built into the airflow channel, or at least partially pass through the airflow channel, which makes the conductive wires contaminated by sweat and other stains and rust. With the extension of the usage time, the conductive wires will also break.

[0024] Therefore, this application provides an electrotherapy adsorption bowl that can, to a certain extent, prevent the conductive wires electrically connected to the metal electrodes from rusting and breaking, thereby improving the service life of the electrotherapy adsorption bowl.

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, Figure 1 This is a schematic cross-sectional view of the electrotherapy adsorption bowl provided in an embodiment of this application.

[0027] In one specific embodiment of this application, the electrotherapy adsorption bowl may include:

[0028] Bowl structure 1; metal electrode 2 disposed inside the bowl structure 1; channel portion 3 disposed at the bottom of the bowl structure 1, the channel portion 3 having a first channel 31 and a second channel 32 that are isolated from each other;

[0029] The first channel 31 is provided with a conductive wire 4, one end of which is electrically connected to the metal electrode 2 and the other end of which is electrically connected to the power supply; one end of the second channel 32 is connected to the air inside the bowl structure 1, and the other end is connected to the air inside the negative pressure pump.

[0030] like Figure 1 As shown, the bowl structure 1 in this embodiment is a semi-closed structure whose rim is used to adhere to the surface of human skin, forming a negative pressure cavity together with the surface of human skin. The bowl structure 1 in this embodiment can be a rigid bowl, such as a transparent plastic bowl, which can maintain its structure and prevent deformation when adsorbing onto the surface of human skin, thus avoiding air leakage due to unstable deformation of the bowl structure 1. In addition, in order to improve the sealing between the bowl structure 1 and the surface of human skin, a rubber ring can be set around the edge of the rim of the bowl structure 1.

[0031] Based on this, a channel portion 3 is further provided at the bottom of the bowl structure 1, and the channel portion 3 contains a first channel 31 and a second channel 32 that are isolated from each other; such as Figure 1 As shown, in Figure 1 In the embodiment shown, the first channel 31 and the second channel 32 are arranged substantially parallel to each other within the channel section 3.

[0032] The first channel 31 is used to accommodate the conductive wire 4. The metal electrode 2 is located at the lower end of the first channel 31, that is, at the end of the first channel 31 near the rim of the bowl structure 1. This allows the metal electrode 2 to be electrically connected to the conductive wire 4 through the lower port of the first channel 31, and then to be electrically connected to the external power supply, so that the power supply can output an electrical stimulation signal to the human skin through the metal electrode 2.

[0033] The second channel 32 is used to realize the air communication between the negative pressure pump and the internal space of the bowl structure 1. It also provides an airflow channel so that the negative pressure pump can draw air from the closed cavity formed between the bowl structure 1 and the surface of human skin, thereby enabling the bowl structure 1 to adhere tightly to the surface of human skin.

[0034] Based on the above discussion, when the bowl structure 1 is tightly adsorbed onto the surface of human skin, the metal electrode 2 should be attached to the surface of human skin inside the bowl structure 1, making sufficient contact with the surface of human skin to ensure that a conductive path can be formed between it and the human body. To ensure the stability of the contact between the metal electrode 2 and the surface of human skin in this application, in another optional embodiment of this application, the electrotherapy adsorption bowl may further include:

[0035] The section of the first channel 31 near the metal electrode 2 is a vertical section 311 parallel to the central axis of the bowl structure 1; a piston 5 is installed in the vertical section 311; the piston 5 and the metal electrode 2 are fixedly connected.

[0036] When the negative pressure pump draws air from the bowl structure 1 through the second channel 32, making the air pressure in the channel section of the first channel 31 located on the side of the piston 5 away from the metal electrode 2 greater than the air pressure inside the bowl structure 1, the piston 5 drives the metal electrode 2 to move towards the bowl opening of the bowl structure 1.

[0037] like Figure 1 As shown, in this embodiment, the first channel 31 has a vertical section 311, which is parallel to the central axis of the bowl structure 1. A piston 5, movable along the channel of the vertical section 311, is also provided within the vertical section 311. In other words, the vertical section 311 provides a channel for the piston 5 to move along the central axis of the bowl structure 1. (Refer to...) Figure 1 Obviously, the piston 5 can seal the channel section above the piston 5 in the first channel 31, forming a channel space that is airtightly isolated from the internal space of the bowl structure 1. The conductive wire 4 can also be placed in this sealed channel space to avoid being contaminated by sweat.

[0038] It should be noted that, in this embodiment, a sealing ring 51 may also be provided on the outer periphery of the piston 5, thereby increasing the sealing connection between the piston 5 and the channel wall of the first channel 31.

[0039] Furthermore, the lower end of piston 5 is further fixedly connected to metal electrode 2. Thus, when piston 5 moves along the vertical section 311 of the first channel 31, piston 5 can also drive metal electrode 2 to move closer to or further away from human skin. Since the channel space above and below piston 5 in the first channel 31 are airtightly isolated from each other, and the channel space below piston 5 is connected to the space inside the bowl structure 1, when the negative pressure pump draws air from the bowl structure 1 through the second channel 32, reducing the air pressure inside the bowl structure 1, the air pressure in the channel space above piston 5 in the first channel 31 will inevitably be greater than the air pressure in the channel space below piston 5. This pressure difference causes piston 5 to move downwards along the vertical section 311 of the first channel 31, thus allowing metal electrode 2 to adhere to the surface of human skin. Therefore, in this embodiment, by setting the piston 5 in the first channel 31, during the process of the negative pressure pump drawing air into the bowl structure 1 to form a negative pressure cavity, not only can the bowl structure 1 be tightly adsorbed onto the human skin, but the metal electrode 2 can also be driven to adhere to the surface of the human skin, ensuring good contact between the metal electrode 2 and the surface of the human skin, thereby ensuring the reliability of the metal electrode 2 outputting electrical stimulation signals to the human skin.

[0040] In addition, when the negative pressure pump evacuates the air inside the bowl structure 1, in order to ensure that the air pressure in the channel space above the piston 5 is greater than the air pressure in the space below, the end of the first channel 31 away from the piston 5 can be directly connected to the external environment. This ensures that the air pressure in the other sections of the first channel 31, except for the section directly connected to the air inside the bowl structure 1, is always at atmospheric pressure. Thus, the pressure difference between the upper and lower parts of the piston 5 can be used to drive the piston 5 to press down.

[0041] Of course, in practical applications, the port of the first channel 31 that is away from the piston 5 is not necessarily connected to the external environment.

[0042] In another optional embodiment of this application, the port of the first channel 31 facing away from the metal electrode 2 is connected to the air outlet of the negative pressure pump via an air supply pipe; an electromagnetic valve is provided between the air outlet of the negative pressure pump and the air supply pipe.

[0043] In this embodiment, the first channel 31 and the air outlet of the negative pressure pump are connected by air, so that the negative pressure pump can not only evacuate the air inside the bowl structure 1, but also inflate the first channel 31. This allows for more precise control of the pressure difference between the space above and below the piston 5, making the pressure difference larger. This can, to a certain extent, avoid the problem of insufficient negative pressure inside the bowl structure 1 causing the metal electrode 2 to not adhere tightly to the surface of human skin.

[0044] In practical applications, the solenoid valve in this embodiment can be a three-way valve. The input end of the three-way valve is connected to the outlet end of the negative pressure pump, the first output end of the three-way valve is connected to the inlet of the air supply pipe, and the second output end of the three-way valve is connected to the external environment. Thus, by reasonably controlling the opening of the three-way valve, part of the airflow output by the negative pressure pump can be input into the first channel 31, or part can be directly discharged into the external environment, avoiding the problem of excessive air pressure difference between the upper and lower spaces of the piston 5. In addition, the first channel 31 can also be further connected to an exhaust pipe connected to the external environment. A solenoid valve can also be installed on the exhaust pipe. When it is necessary to remove the electrotherapy adsorption bowl from the human skin, the air pressure in the first channel can be released through the exhaust pipe and the solenoid valve, thereby reducing the air pressure difference between the upper and lower spaces of the piston 5.

[0045] Furthermore, considering that during the process of drawing air from the bowl structure 1 through the negative pressure pump to ventilate the first channel 31, air containing sweat or other substances may be discharged into the first channel 31, a drying filter screen can be installed in the air supply pipe in this embodiment, or the drying filter screen can be installed between the second channel 32 and the air inlet end of the negative pressure pump. This embodiment does not specifically limit this.

[0046] In addition, in another optional embodiment of this application, two air pumps can be used to connect to the first channel 31 and the second channel 32 respectively. One air pump is used to inflate the first channel 31, while the other air pump is used to evacuate the inside of the bowl structure 1 through the second channel 32. This can also achieve precise control of the air pressure difference between the upper and lower spaces of the piston 5.

[0047] As described above, the first channel 31 in this application has a vertical section 311 for accommodating the piston 5 to move up and down. In order to prevent the piston 5 from sliding from the vertical section 311 of the first channel 31 into the bowl structure 1, in another optional embodiment of this application, a limiting structure 30 is also provided at the end of the first channel 31 near the metal electrode 2. The limiting structure 30 forms a port with a diameter smaller than the diameter of the piston 5 at the end of the first channel 31 near the metal electrode 2. That is, the diameter of the port of the first channel 31 near the metal electrode 2 is smaller than the diameter of the piston 5, which can prevent the piston 5 from sliding out from the port.

[0048] Based on the above discussion, in an optional embodiment of this application, the electrotherapy adsorption bowl may further include:

[0049] The first channel 31 is an L-shaped channel formed by the vertical section 311 and the horizontal section 312;

[0050] A telescopic spring 41 is also provided in the first channel 31. One end of the telescopic spring 41 is fixedly connected to the surface of the piston 5 away from the metal electrode 2, and the other end is fixedly connected to the inner wall of the corner section of the L-shaped channel.

[0051] like Figure 1 As shown, the first channel 31 and the second channel 32 in this application are roughly parallel L-shaped channels. A telescopic spring 41 is further provided within the vertical section 311 of the first channel 31. When the air pressure above the piston 5 is greater than the air pressure below it, causing it to slide downwards and thus move the metal electrode 2 closer to the skin, the telescopic spring 41 is stretched accordingly. When the air pressure in the first channel 31 and the air pressure in the bowl structure 1 are approximately the same, the telescopic spring 41 pulls the piston 5 upwards, causing the metal electrode 2 to move upwards with the piston 5 and retract back into the bowl structure 1, away from the bowl opening.

[0052] Furthermore, the telescopic spring 41 in this application can also be a conductive spring and serve as a section of the conductive wire 4.

[0053] like Figure 1 As shown, the metal electrode 2 in this application is fixedly connected to the piston 5 via a stainless steel metal column 6. The end of the metal column 6 facing away from the metal electrode 2 can pass through the piston 5 and be electrically connected to the telescopic spring 41. The telescopic spring 41 acts as part of the conductive wire 4, and the end of the telescopic spring 41 facing away from the metal column 6 is further connected to another section of the conductive wire 4. The telescopic spring 41 is electrically connected to the power supply through this section of the conductive wire 4, thereby realizing the electrical connection between the metal electrode 2 and the power supply. Therefore, the telescopic spring 41 in this application can simultaneously adjust the position of the piston 5 and realize the electrical connection between the metal electrode 2 and the power supply, simplifying the internal structure of the electrotherapy adsorption bowl to a certain extent.

[0054] In summary, this application incorporates two isolated channels—a first channel and a second channel—located within the bottom of the bowl structure. These two channels serve as a conduit for the conductive wires and an airflow channel for evacuating air from the bowl structure, respectively. Consequently, when the negative pressure pump evacuates air from the bowl structure through the second channel, sweat and other substances generated on the surface of human skin will only enter the second channel and will not enter the first channel where the conductive wires are located. This effectively prevents the conductive wires from rusting and breaking due to corrosion caused by sweat and other substances, thereby extending the lifespan of the electrotherapy adsorption bowl.
