Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation medical equipment, in particular to a heating adsorption electrode. Background Art

[0002] Electrical stimulation is a safe, non-invasive and commonly used treatment for muscle dysfunction. It can help patients restore paralyzed muscle function and strength, relieve chronic pain, improve their quality of life and enhance their physical function.

[0003] Electrodes are required in electrical stimulation therapy devices. The treatment device generates pulse current and transmits it to the electrode. The electrode contacts the human skin, and then the pulse current is transmitted to the human body, causing physiological effects, thereby achieving the purpose of treatment. There are many forms of electrodes. Adsorption electrodes are a commonly used electrical stimulation electrode. Adsorption electrodes can be combined with negative pressure to make the electrode contact with the skin more closely.

[0004] The common adsorption electrodes on the market have no heating function due to volume limitations, which will cause patients to feel uncomfortable when used in winter. In response to this, the applicant previously applied for an adsorption electrode preheating device, CN219185605U, which can preheat the adsorption electrode before use. However, it can only achieve preheating, but cannot maintain the temperature. The temperature cannot be kept constant when the electrode is used, making it difficult to achieve the effect of thermal therapy. Summary of the invention

[0005] In order to solve the problem that conventional adsorption electrodes cannot be heated and cannot perform thermotherapy, the utility model provides a heating adsorption electrode, optimizes the adsorption electrode structure, and installs a heating column and a temperature probe inside the adsorption electrode, so that the adsorption electrode has a heating function and achieves a thermotherapy effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A heating adsorption electrode, comprising a silicone leather cup, a metal bracket, a ceramic heating column, a temperature probe, a gas-electric connector and a metal electrode sheet;

[0008] The metal bracket is arranged inside the silicone leather cup to facilitate partial support of the silicone leather cup to prevent its deformation. The metal bracket is hollow inside. The ceramic heating column and the temperature probe are arranged inside the metal bracket to realize the heating and temperature monitoring functions of the adsorption electrode. The metal electrode sheet is arranged below the metal bracket to facilitate the transmission of pulse current to the human body. The ceramic heating column, the temperature probe and the metal electrode sheet are arranged in sequence up and down;

[0009] One end of the gas-electric connector passes through the silicone leather cup and is threadedly connected to the metal bracket. The gas-electric connector and the metal bracket are internally connected, which is convenient for ventilation and the insertion of wires. A nut is also threadedly connected to the gas-electric connector, and the nut is tightly against the side wall of the silicone leather cup, which facilitates the installation and fixation of the gas-electric connector.

[0010] Furthermore, the silicone leather cup includes a connecting section and an adsorption section integrally formed at the upper and lower ends. The connecting section is a hollow cylinder with an opening at the lower end, which is equivalent to the hand-held part of the silicone leather cup. The connecting section is connected downwardly to the adsorption section. The adsorption section is a hollow truncated cone with a "︹"-shaped cross-section. This is the part that is deformed due to negative pressure and is tightly adsorbed on human skin.

[0011] Furthermore, the metal bracket is coaxially arranged in the connecting section to facilitate supporting the connecting section. The metal bracket is downwardly connected to the metal electrode sheet. The diameter of the metal electrode sheet is larger than the diameter of the metal bracket. The metal electrode sheet is arranged above the adsorption section. A limiting ring is also provided in the adsorption section, and the metal electrode sheet is placed in the limiting ring.

[0012] Furthermore, the metal bracket is a hollow stepped cylinder, the upper part of the metal bracket has a large diameter, and a mounting hole is provided on the upper part of the metal bracket. The mounting hole radially penetrates the metal bracket, and one end of the gas-electric connector is threadedly connected to the mounting hole, which facilitates the installation of the gas-electric connector;

[0013] The lower part of the metal bracket has a small diameter, and there is a gap between the outer wall of the lower part of the metal bracket and the inner wall of the connecting section to form an air outlet ring. The lower part of the metal bracket is provided with an air vent, which radially penetrates the metal bracket to facilitate the flow of negative pressure.

[0014] Furthermore, the internal space of the metal bracket is a vertical placement channel, and the placement channel penetrates the metal bracket upward, and the gas-electric connector, the placement channel, the vent hole and the air outlet ring channel are connected. The ceramic heating column and the temperature probe are arranged in sequence up and down in the placement channel.

[0015] Through the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model has a reasonable structural design. A metal bracket is arranged in the silicone leather cup. A ceramic heating column and a temperature probe are arranged in the upper and lower parts of the metal bracket. The metal bracket has good thermal conductivity. The heat generated by the ceramic heating column can directly transfer heat to the metal electrode sheet. When the patient is receiving electrical stimulation treatment, the silicone leather cup is tightly adsorbed on the surface of the human skin under the action of negative pressure. The skin is in contact with the heated metal electrode sheet, which reduces discomfort and can fully transfer the heating effect to achieve the effect of thermal therapy. During the heating process, the temperature is monitored in real time by the temperature probe to ensure safer heating treatment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0022] like Figure 1~Figure 3 As shown, a heating adsorption electrode includes a silicone leather cup 1, a metal bracket 2, a ceramic heating column 3, a temperature probe 4, an air-electric connector 5 and a metal electrode sheet 6.

[0023] The silicone leather cup 1 is a bowl-shaped structure made of flexible silicone. The silicone leather cup 1 includes a connecting section 101 and an adsorption section 102 which are integrally formed at the top and bottom. The connecting section 101 is a hollow cylinder with an opening at the bottom. The upper end of the connecting section 101 is closed. The connecting section 101 is connected downwardly to the adsorption section 102. The adsorption section 102 is a hollow truncated cone with a "︹"-shaped cross section. The adsorption section 102 can be elastically deformed after being pressed by an external force.

[0024] A metal bracket 2 is arranged inside the silicone leather cup 1, and the metal bracket 2 can support the silicone leather cup 1 to a certain extent from the inside to improve its anti-deformation ability. The metal bracket 2 is a hollow stepped cylinder, and the metal bracket 2 is coaxially arranged inside the connecting section 101, and can support the connecting section 101 to prevent its elastic deformation.

[0025] The metal bracket 2 is hollow inside and can provide installation space for other components, so a ceramic heating column 3 and a temperature probe 4 are arranged inside the metal bracket 2. Specifically, the internal space of the metal bracket 2 is a vertical placement channel 9, and the placement channel 9 and the metal bracket 2 are coaxially arranged inside and outside, and the ceramic heating column 3 and the temperature probe 4 are arranged in sequence in the placement channel 9 from top to bottom.

[0026] The placement channel 9 axially penetrates the metal bracket 2 upward, which can facilitate the placement of the ceramic heating column 3 and the temperature probe 4, that is, through the opening position at the top of the metal bracket 2, the ceramic heating column 3 and the temperature probe 4 can be placed into the metal bracket 2. The ceramic heating column 3 heats the metal bracket 2, and the temperature probe 4 can monitor the temperature of the metal bracket 2 in real time.

[0027] A metal electrode sheet 6 is arranged under the metal bracket 2, that is, the metal bracket 2 is connected to the metal electrode sheet 6 downward, so that the ceramic heating column 3, the temperature probe 4 and the metal electrode sheet 6 are arranged in sequence up and down, so that the heat on the metal bracket 2 can be transferred to the metal electrode sheet 6.

[0028] The diameter of the metal electrode sheet 6 is larger than that of the metal bracket 2. The metal electrode sheet 6 is only arranged above the adsorption section 102 and does not affect the deformation of the adsorption section 102. In order to limit the metal electrode sheet 6, a limit ring 8 is also provided in the adsorption section 102, and the metal electrode sheet 6 is placed in the limit ring 8.

[0029] Specifically, the limiting ring 8 includes a ring body 1 81 and a ring body 2 82, which are coaxially arranged inside and outside, and the ring body 1 81 allows a gap to exist between the metal electrode sheet 6 and the adsorption section 102, and the ring body 2 82 is arranged around the metal electrode sheet 6 to prevent it from moving radially. The limiting ring 8 and the adsorption section 102 are an integral structure, so when the adsorption section 102 is deformed, the limiting ring 8 can be separated from the metal electrode sheet 6.

[0030] Since the heating adsorption electrode needs to be powered and connected to negative pressure, a gas-electric connector 5 is required to allow air to enter and realize circuit wiring. When the gas-electric connector 5 is installed, one end of the gas-electric connector 5 passes through the silicone leather cup 1 and is threadedly connected to the metal bracket 2. Specifically, the upper part of the metal bracket 2 has a large diameter, and a mounting hole 10 is opened on the upper part of the metal bracket 2. The mounting hole 10 radially penetrates the metal bracket 2, and the mounting hole 10 is vertically connected to the placement channel 9. One end of the gas-electric connector 5 is threadedly connected to the mounting hole 10.

[0031] In order to ensure the tightness of the gas-electric connector 5, a nut 7 is also threadedly connected to the gas-electric connector 5, and the nut 7 is tightly against the side wall of the silicone leather cup 1. On the basis of the threaded connection between the gas-electric connector 5 and the metal bracket 2, the nut 7 can ensure the reliable installation of the gas-electric connector 5 and prevent the gas-electric connector 5 from axial movement.

[0032] After installation, the gas-electric connector 5 is connected to the inside of the metal bracket 2, that is, connected to the placement channel 9. In order to provide a negative pressure flow channel for the heating adsorption electrode, the lower diameter of the metal bracket 2 is small, and there is a gap between the outer wall of the lower part of the metal bracket 2 and the inner wall of the connecting section 101 to form an outlet ring channel 12. At the same time, a vent hole 11 is opened at the lower part of the metal bracket 2, and the vent hole 11 radially penetrates the metal bracket 2. As a result, the gas-electric connector 5, the placement channel 9, the vent hole 11 and the outlet ring channel 12 are connected to form a channel for negative pressure flow.

[0033] The principle of the utility model is: the gas-electric connector 5 is externally connected to a vacuum pump and a power supply, which can provide negative pressure and power for the heating adsorption electrode. When the heating adsorption electrode is used, the ceramic heating column 3 is energized to make it heat up and conduct it to the metal bracket 2 and the metal electrode sheet 6. The temperature of the metal bracket 2 and the metal electrode sheet 6 is monitored by the temperature probe 4 to achieve direct heating of the heating adsorption electrode.

[0034] The vacuum pump is started to generate negative pressure in the silicone cup 1, and the silicone cup 1 is manually pressed to deform and fix on the patient's skin surface by negative pressure adsorption. At this time, the patient's skin is in direct contact with the metal electrode sheet 6 with a certain suitable temperature, and the effect of thermal therapy can be achieved. During the treatment process, the temperature probe 4 monitors the temperature in real time to ensure the safety and reliability of the treatment process.

[0035] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
