Description

Technical Field

[0001] The present invention relates to the technical field of hemiplegia meridian stimulation devices, and in particular to a limb hemiplegia meridian stimulation device for stroke. Background Art

[0002] At present, the electrostimulation therapy technology for acupoints and meridians has a certain effect on the treatment of hemiplegia. Meridians are the channels for the qi and blood circulation in the human body. Stroke patients will have limb hemiplegia, numbness, abnormal sensations, etc. due to the unsmooth qi and blood circulation in the meridians after stroke. By stimulating the Yangming meridian, the qi and blood on the hemiplegic side can be dredged, blood circulation can be promoted, and limb function can be improved. As early as in "Huangdi Neijing", it was proposed that "for the treatment of flaccidity, only select the Yangming meridian." There are two meanings for selecting the Yangming meridian: the Yangming meridian is the sea of zang-fu organs and the source of biochemistry; the Yangming meridian is mainly responsible for moistening the tendons, and the tendons are mainly responsible for binding the bones and facilitating the joints. By acupuncture and combined with bioelectricity, the local meridian qi and blood circulation can be promoted to achieve the rehabilitation of limb function in stroke hemiplegia patients.

[0003] The problems existing in the current electrostimulation of acupoints are that during the electrostimulation treatment, some patients are prone to sweating, resulting in a decrease in skin resistance. Under the dual action of sweat and electrostimulation, the electrolytes in the sweat react, causing irritation to the skin, resulting in allergic phenomena such as skin redness, ulceration, and blisters. Especially the electrode patches that adhere for a long time are more likely to cause skin damage under the stimulation of sweat. After sweating, the skin resistance decreases, the current stimulation to the human body increases, and pain is likely to occur. The stimulation is relatively large and it is also easy to lead to poor treatment effects.

[0004] There are two existing electrostimulation devices. One is to apply an electric current to the acupuncture needles after inserting the acupuncture needles into the acupoints to achieve the stimulation of the acupoints. The other is to use a patch layer to act on the skin surface of the human body, and then apply an electric current to the patch layer to achieve the stimulation of human tissues. Among them, the stimulation applied by acupuncture can directly act on the acupoints of the human body, and the stimulation depth is deeper, but the coverage area is smaller. While the stimulation applied by the patch layer has a wider coverage area, but the stimulation depth is shallower and it is not easy to reach the deep acupoints. Based on the above situation, it is necessary to design a limb hemiplegia meridian stimulation device for stroke to solve the above problems. Summary of the Invention

[0005] The present invention provides a limb hemiplegia meridian stimulation device for stroke, which is provided with ventilation grooves on the patch layer and is matched with an external air flow driving component to prevent the human body from sweating during the electrostimulation treatment, resulting in damage to human tissues. By combining the electrode patch and the puncture needle, the coverage area and depth during the electrostimulation treatment can be ensured, and the treatment effect can be guaranteed.

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0034] In order to enable those skilled in the art to know the inventive points of the present invention, first, the prior art related to the present invention will be introduced. Refer to Figure 8 and Figure 9 , where Figure 9 is a schematic diagram of the current use of electrode patches to electrically stimulate the muscles and nerves of the human body. The positive electrode patch 23 and the negative electrode patch 24 are respectively attached to the skin of the human body. When the positive electrode patch 23 and the negative electrode patch 24 are energized, the current flows from the positive electrode patch 23 through the human tissue 21 and then to the negative electrode patch 24 (I in the figure represents the direction of the current). It can be seen from the figure that the flow path of the current generally only moves in the shallow layer of the human tissue 21, and the stimulation effect on the deep acupoints 22 is poor. However, because the electrode patches cover a sufficient area, the stimulation range of the human tissue 21 is relatively wide. Refer to Figure 8 , which is a schematic diagram of the current use of a puncture needle 20 (acupuncture needle) for electrical stimulation. During the electrical stimulation process, first, two puncture needles 20 are respectively punctured corresponding to two acupoints 22, and then an electric current is applied to the puncture needles 20 corresponding to the two acupoints 22. The current flows from one puncture needle 20 to the other puncture needle 20 to achieve the stimulation of the human acupoints 22. This method can directly act on the acupoints 22 deep in the human tissue 21 to achieve electrical stimulation, but the area of electrical stimulation is small, and the stimulation effect on muscles and nerves is poor.

[0035] In the electrical stimulation methods of the above two schemes, the stimulation of the electrode patch is mainly applied in Western medicine, while the method of the puncture needle 20 pays attention to the acupoints 22 and meridians and is widely used in traditional Chinese medicine. No matter which method is used to perform electrical stimulation on the human body, sweating will occur during the electrical stimulation process. When the human body sweats, the skin resistance will decrease. Under the dual stimulation of sweat stimulation and electrical stimulation, allergic phenomena such as skin redness, ulceration, and blisters are likely to occur. At the same time, the resistance value of the skin decreases, the stimulation of the current to the human body increases, and pain is likely to occur. With a larger stimulation, it is also easy to lead to poor treatment effects.

[0036] Based on the above situation, the present invention provides a meridian stimulation device for hemiplegia of the limbs in stroke, as Figure 1 - Figure 4 shown. It includes a main control device 1, an application layer 4, and an air flow driving component. The main control device 1 is used to generate and adjust the electrical stimulation current. Its adjustment of the electrical stimulation current includes adjusting the magnitude, frequency, waveform, etc. of the current. The electrical stimulation current is output through the positive electrode connector 2 at the end of the wire at the output end of the main control device 1 and input through the negative electrode connector 3. The application layer 4 is used to contact the skin of the human body. The difference between the application layer 4 of the present invention and the above-mentioned electrode patch is that the application layer 4 of the present invention includes two electrode patches (the first electrode patch 5 and the second electrode patch 6) and an insulating layer 9 in the middle of the two electrode patches. The insulating layer 9 and the two electrode patches are all in the same plane. The effect of the insulating layer 9 is to realize the physical connection of the two electrode patches and at the same time block the direct electrical connection between the two electrode patches to avoid short circuits. Wiring posts are provided on the two electrode patches for connecting with the positive electrode connector 2 and the negative electrode connector 3 at the end of the wire of the main control device 1. When the positive electrode connector 2 and the negative electrode connector 3 are respectively connected to the wiring posts on the two electrode patches through two wiring posts (the first wiring post 7 and the second wiring post 8), and when the application layer 4 is attached to the skin of the human body, the current flows out from the main control device 1, passes through the positive electrode connector 2 and then enters one electrode patch, and then passes through the human body and returns to the inside of the main control device 1 from the other electrode patch and the negative electrode connector 3, thereby realizing the stimulation of the human tissue 21.

[0037] In order to prevent the application layer 4 from sweating due to airtightness and the heat generated by electrical stimulation during the process of applying electrical stimulation to the human body, a ventilation groove 10 is provided on the side of the application layer 4 for attaching to the skin of the human body. The ventilation groove 10 penetrates the side wall of the application layer 4 to improve the air permeability effect of the application layer 4 and reduce sweating. At the same time, in order to make the air flow better inside the through groove of the application layer 4, the present invention also provides an air flow driving component. The air flow driving component drives the air flow speed inside the ventilation groove 10 through positive pressure or negative pressure to reduce the accumulation of sweat on the skin surface.

[0038] Further, the air flow driving component includes a pump body 102, a gas pipeline 14 connected to the pump body 102, and an air flow channel 12 formed on the patch layer 4. During use, the gas pipeline 14 is communicated with the air flow channel 12, and the pump body 102 operates to realize air extraction or exhaust of the gas pipeline 14. The air flow channel 12 drives the air flow channel 12 to exhaust or extract air. During the process of exhausting or extracting air, the air flow channel 12 will take away the sweat on the skin surface. Compared with the traditional electrode patch, after the patch layer 4 of the present invention adheres to the skin, it can form an air duct through the air flow channel 12 to realize the flow of air, so as to cool the skin and avoid the accumulation of sweat.

[0039] Further, in order to facilitate the connection between the gas pipeline 14 and the air flow channel 12, the air flow driving component further includes a housing cover 11 installed on the back side of the patch layer 4. An air flow chamber 1101 is defined by the side wall of the housing cover 11 and the back side of the patch layer 4. An inflation joint 13 is provided on the housing cover 11 and is detachably connected to the gas pipeline 14. That is, during use (taking the air extraction of the pump body 102 as an example), the air flow direction is that the external air enters the inside of the ventilation groove 10 from the side wall of the patch layer 4, then enters the inside of the air flow chamber 1101 along the air flow channel 12, and then enters the inside of the gas pipeline 14 along the inflation joint 13 from the inside of the air flow chamber 1101 and enters the pump body 102 to realize the air flow, as Figure 5 shown. The terminal mentioned above and the connector of the skin resistance sensor 18 mentioned below are both provided with a sealed channel on the housing to facilitate the terminals and the connector of the skin resistance sensor 18 to pass through without affecting the sealing effect of the air flow chamber 1101 (the air flow chamber 1101 is only communicated with the outside through the air flow channel 12 and the inflation joint 13, and other positions are closed).

[0040] As Figure 7As shown, of course, the pump body 102 can also be set to an exhaust state to avoid sweating on the skin. Specifically, the pump body 102 exhausts through the gas pipeline 14. The gas passes through the air flow chamber 1101 and then is discharged outward from the ventilation groove 10. In this case, in order to ensure the constancy of the skin temperature, a heating wire 15 and a temperature sensor 16 are provided inside the gas pipeline 14 in the present invention. The temperature sensor 16 is used to monitor the air temperature inside the gas pipeline 14. The output end of the temperature sensor 16 is connected to the input end of the main control device 1 to provide the main control device 1 with the air temperature signal inside the gas pipeline 14. The output end of the main control device 1 is used to output a control signal, and the control signal is used to control the operation of the heating wire 15. When the main control device 1 controls the pump body 102 to act, the air flow is heated through the heating wire 15. When the air temperature detected by the temperature sensor 16 is relatively high, the main control device 1 controls the heating wire 15 to operate in a low-power state. When the temperature sensor 16 detects that the air temperature is relatively low, the main control device 1 controls the heating wire 15 to operate in a high-power state, thereby ensuring the constancy of the gas temperature.

[0041] Furthermore, in order to control the pump body 102 to operate when the human body sweats, a skin resistance sensor 18 is also provided on the patch layer 4. The output end of the skin resistance sensor 18 is connected to the input end of the main control device 1 to provide the main control device 1 with the skin resistance signal of the human body. When the skin resistance sensor detects that the resistance value of the skin decreases to a set threshold due to sweating, the main control device 1 controls the air flow driving component to operate, so that the air flow takes away the sweat on the human body surface. When the skin resistance sensor 18 monitors that the resistance value of the skin recovers, the main control device 1 controls the air flow driving component to stop operating. The skin resistance sensor 18 is detachably installed on the patch layer 4. The specific installation method is that an installation groove 19 is provided on the patch layer 4 for placing the skin resistance sensor 18. The installation groove 19 penetrates the patch layer 4 to facilitate the connection between the joint of the skin resistance sensor 18 of the main control device 1 and the inductive resistance joint 17 at the end of the wire of the main control device 1.

[0042] The above is the introduction of the solution of the present invention for applying electrical stimulation to the human body using the patch layer 4. The patch layer 4 as a whole should be made of a soft material (for example, the motor patch is made of conductive rubber, and the insulating layer 9 is made of insulating rubber). The corresponding shell 11 can also be made of a soft material, such as silica gel, rubber, etc., which will not be elaborated in detail here. Through the above solution, a series of adverse reactions caused by sweating of the human body during the electrical stimulation process can be avoided. At the same time, the present invention also adopts a combination with the puncture needle 20 to further ensure the treatment effect of the electrical stimulation, specifically as follows.

[0043] As Figure 6As shown in the figure, a puncture needle 20 is added to the above-mentioned meridian stimulation device for hemiplegia of the limbs caused by stroke. During use, the puncture needle 20 punctures the electrode patch, and the current of the electric shock patch reaches the deep part of the human tissue 21 through the puncture needle 20, realizing better stimulation of the human tissue 21. For example, Figure 10 As shown in the figure, the present invention also has differences from the existing electric stimulation devices during use. That is, the positions where the puncture needles 20 of the present invention penetrate into the human tissue 21 are on both sides of the acupoint 22. When the attachment layer 4 is attached to the human skin, the central position of the insulating layer 9 is attached corresponding to the skin surface of the acupoint. The two puncture needles 20 pass through the electrode patch and enter the human tissue 21, ensuring that sufficient current passes through the acupoint 22 and at the same time ensuring the area of electric stimulation.

[0044] Furthermore, the main control device 1 of the present invention includes a control main board 101, a display screen and buttons, which are formed into a whole by a housing. The above-mentioned pump body 102 can be inside the housing, and of course can also be arranged outside the housing. Among them, the control main board 101 is mainly used to control each component to cooperate with each other. The display screen is used to display the human-computer interaction interface (parameter display interface and parameter setting interface), and the buttons are used to set the operating parameters of the main control device 1 according to the human-computer interaction interface.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
