Description

Technical Field

[0001] The utility model relates to an electrode sheet product for medium and low frequency treatment equipment, specifically to a composite temperature control electrode sheet. Background Art

[0002] Medium frequency / low frequency treatment equipment is a special instrument that applies electrical stimulation to the human body using modulated current and thus has certain therapeutic effects. It is mainly used for functions such as analgesia, promoting blood circulation in local tissues, and exercising muscles.

[0003] In obstetrics and gynecology, medium frequency / low frequency treatment equipment is usually used for physical therapy of such conditions in the chest, and the treatment effect is obvious.

[0004] Among them, the electrode sheet is the output end of the medium frequency / low frequency treatment equipment and is used to contact human tissues.

[0005] Currently, traditional electrode sheets only include a silica gel layer and a structural layer. Directly applying them to the human body surface during treatment will bring a feeling of cold for a period of time, which is particularly obvious in winter, affecting the comfort experience of treatment. Especially for such equipment applied in obstetrics and gynecology, the electrode sheet needs to cover most of the chest, and the comfort requirement is relatively higher.

[0006] Some developers have added a temperature-rising structure to the electrode sheet, which can preheat the electrode sheet before application to improve comfort. However, the temperature control mainly depends on the controller integrated in the medium frequency / low frequency treatment equipment, and there is only gear setting, and the adjustment ability is relatively poor, and the comfort experience needs to be upgraded. Summary of the Utility Model

[0007] The purpose of the utility model is to address the deficiencies of the prior art, and thus provide a composite temperature control electrode sheet with better temperature regulation ability and better use comfort.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is: a composite temperature control electrode sheet, including a skin-friendly layer, a heating layer, an electrical stimulation layer, an insulating layer, a sensor layer, and an isolation protection layer stacked in sequence;

[0009] The skin-friendly layer is a silica gel layer and is used to contact human skin;

[0010] The heating layer is a flexible heating film. The heating layer is in direct contact with the skin-friendly layer, and the heating layer is provided with a wire for external connection to a device;

[0011] The electrical stimulation layer is a flexible conductive material layer. The electrical stimulation layer transmits current to the skin-friendly layer through the heating layer or transmits current to the skin-friendly layer through the wire. The electrical stimulation layer is also provided with a wire for external connection to a device;

[0012] The insulating layer is disposed above the electrical stimulation layer for isolating the electrical stimulation layer and the sensor layer;

[0013] The sensor layer is provided with a temperature sensor, and the temperature sensor is connected with a wire for an external device;

[0014] The isolation and protection layer is used for covering above the sensor layer and around other layers for protecting each layer from being isolated from the outside;

[0015] After passing through the isolation and protection layer, each wire is bundled to form an external bundled line.

[0016] Preferably, a microcontroller is integrated outside the sensor layer or the isolation and protection layer. The wires of the heating layer and the temperature sensor are connected to the microcontroller to form a temperature feedback adjustment module for controlling the heating power of the heating layer according to the temperature collected by the temperature sensor. The microcontroller is provided with power supply and signal transmission wires through the external bundled line.

[0017] Preferably, the heating layer is a carbon nanotube heating film.

[0018] Preferably, the electrical stimulation layer is a carbon fiber tissue or a silver paste coating.

[0019] Preferably, a skin resistance sensor is further included. The skin resistance sensor includes two microelectrodes with a span integrated in the skin-friendly layer. The acquisition ends of the two microelectrodes extend beyond the surface of the skin-friendly layer, and other areas of the two microelectrodes are insulated from the skin-friendly layer. The two microelectrodes are bundled in the external bundled line or connected to the microcontroller for detecting the skin resistance within a set span.

[0020] Preferably, the composite temperature control electrode sheet is integrally sheet-shaped.

[0021] Preferably, the composite temperature control electrode sheet is integrally in a fan shape. After the fan-shaped composite temperature control electrode sheets are surrounded, a conical shape with a hole in the middle is formed for fitting with the chest contour.

[0022] Preferably, the isolation and protection layer is made of a waterproof and insulating rubber material.

[0023] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0024] 1. Integrated with a temperature sensor, the temperature sensor is used to sense the temperature change in the electrode sheet in real time, collect and feedback it to the control end, and the control end can adjust the power of the heating layer according to the sensed actual temperature, realizing more accurate and flexible temperature control and improving the comfort of wearing.

[0025] 2. The skin-friendly layer, heating layer, electrical stimulation layer, insulation layer, sensor layer, etc. are all made of flexible materials, which have better drapability. Especially when used for chest physiotherapy, under the large-area coverage requirement, the flexible structure can better adapt to the draping requirements of different shapes and has stronger comfort.

[0026] 3. Add a skin resistance sensor to detect the skin resistance condition, so as to adjust the output parameters of the electrical stimulation according to the resistance condition.

[0033] The technical solutions of the present utility model will be further described in detail below through specific embodiments.

[0034] As Figure 1 shown, a composite temperature-controlled electrode patch includes a skin-friendly layer 1, a heating layer 2, an electrical stimulation layer 3, an insulation layer 4, a sensor layer 5, and an isolation protection layer 6 stacked in sequence.

[0035] The skin-friendly layer 1 is a silicone layer for contacting the human skin. The silicone layer has low allergenicity, breathability, and good biocompatibility, and has a certain viscosity. Generally, medical-grade silicone is used, which can ensure that allergic reactions are reduced when the electrode patch contacts the skin, and at the same time maintain good electrical conductivity and breathability.

[0036] The heating layer 2 is a flexible heating film. In this embodiment, a carbon nanotube heating film is selected. The heating layer is in direct contact with the skin-friendly layer, and the heating layer is provided with a wire for connecting to an external device. This kind of heating film is currently widely used in various wearable products. Its characteristics are thin thickness, high heating efficiency, strong flexibility, good heating uniformity, and can provide good preheating ability for the electrode patch.

[0037] The electrostimulation layer 3 is a flexible conductive material layer. In this embodiment, carbon fiber tissue or silver paste coating is used. The electrostimulation layer transmits current to the skin-friendly layer through the heating layer or transmits current to the skin-friendly layer through the wire. The electrostimulation layer is also provided with a wire for connecting to an external device.

[0038] In principle, both carbon fiber tissue and silver paste coating belong to conductive materials and will also generate heat, but their heating ability and uniformity are inferior to those of the carbon nanotube heating film. Therefore, the electrostimulation layer is designed to be mainly used for conducting electricity. In this embodiment, since the heating layer selects a carbon nanotube heating film, usually such a film is designed with an insulating layer to prevent electric leakage. Therefore, in this embodiment, the electrostimulation layer 3 transmits current to the skin-friendly layer 1 through a wire.

[0039] The heat energy generated by itself is used as auxiliary heat energy.

[0040] The insulating layer 4 is arranged above the electrostimulation layer 3 to isolate the electrostimulation layer 3 and the sensor layer 5 and prevent the sensors in the sensor layer 5 from being interfered.

[0041] The sensor layer 5 is provided with a temperature sensor 8. The temperature sensor is connected with a wire for connecting to an external device. Its main function is to sense the human body temperature. Specifically, a thermocouple or an infrared temperature sensor can be used to monitor the temperature of the electrode patch in real time. In this embodiment, the empty positions of the sensor layer 5 can be filled with flexible materials, such as soft plastic materials, or a tearable mother-and-child sticker structure layer, so that the temperature sensor 8 can be taken out.

[0042] The isolation and protection layer 6 is used to cover above the sensor layer and around other layers to protect each layer from being isolated from the outside and play a protective role. In this embodiment, the isolation and protection layer is made of a waterproof and insulating rubber material.

[0043] Each of the wires passes through the isolation and protection layer and is bundled to form an external bundled line 7.

[0044] Principle description:

[0045] In this embodiment, the electrode patch integrates a temperature sensor and a heating layer, which complement each other. By detecting temperature changes and feeding them back to the control unit of the medium-frequency / low-frequency treatment device, the control unit can adjust the output temperature automatically according to the feedback temperature or manually by the operator, greatly improving flexibility.

[0046] In some embodiments of its structural design, the composite temperature control electrode patch is generally sheet-shaped and can be used for physical therapy in relatively flat areas of the human skin.

[0047] In other embodiments, as Figure 4 shown, the composite temperature control electrode patch is generally fan-shaped. After the fan-shaped composite temperature control electrode patches are enclosed, they form a conical shape with a hole in the middle, which is used to fit the chest contour and is mainly used for postpartum physical therapy in obstetrics and gynecology.

[0048] In a more preferred embodiment, as Figure 2 shown, a microcontroller 9 is integrated outside the sensor layer 5 or the isolation and protection layer 6. The wires of the heating layer 2 and the temperature sensor 8 are connected to the microcontroller 9 to form a temperature feedback adjustment module, so as to control the heating power of the heating layer 2 according to the temperature collected by the temperature sensor 8. The microcontroller 8 is provided with power supply and signal transmission wires through an external bundled line.

[0049] Its advantage is that the control component is integrated in the electrode patch. Since temperature control mainly lies in the process of signal transmission and there are no other additional complex electronic components, integrating it into the electrode patch is more conducive to equipment transformation. Without much improvement to the medium-frequency / low-frequency treatment device itself, the function of temperature control can be added.

[0050] In another embodiment, as Figure 3 shown, it further includes a skin resistance sensor 10. The skin resistance sensor 10 includes two microelectrodes with a span integrated in the skin-friendly layer. The acquisition ends of the two microelectrodes extend beyond the surface of the skin-friendly layer, and other areas of the two microelectrodes are insulated from the skin-friendly layer. The two microelectrodes are bundled by wires in the external bundled line or connected to the microcontroller to detect the skin resistance within the set span.

[0051] Its function is to collect skin parameters, which can evaluate the skin condition and even be used as a reference parameter for evaluating the skin treatment effect. In this embodiment, it is mainly used to detect the skin resistance and evaluate the effect of electrical stimulation, so that the staff can judge whether it is necessary to adjust the electrical stimulation parameters to make it more flexible.

[0052] Finally, it should be noted that the above has described in detail the preferred embodiments of this patent. However, this patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of this patent within the scope of knowledge possessed by those of ordinary skill in the art.
