Description

Technical Field

[0001] The utility model relates to the field of myoelectricity detection equipment, in particular to a disposable electrode sheet which is convenient to assemble and disassemble. Background Art

[0002] There are many types of electrodes, including some that can conduct action potentials generated when muscles are excited, such as ECG electrodes and medical electrodes. Since this type of electrode needs to be adhered to the patient's skin to realize its function, most of this type of electrode is a soft structure.

[0003] Because the electrode sheet generally needs to be connected to the connector before it can conduct electricity when in use, the soft-structured electrode sheet will be difficult to connect to the connector due to the soft material of the connecting end, and the operation of connecting the electrode sheet to the connector will also be particularly complicated; moreover, after the existing electrode sheet is directly pasted to the patient's skin surface, bacteria, dirt and other substances on the patient's skin can easily cause cleaning problems on the surface of the flexible circuit board on the electrode sheet. Therefore, the electrode sheet needs to be disinfected before and after use, which makes the operation required to perform the electrode sheet when in use particularly cumbersome. Utility Model Content

[0004] In view of the above technical deficiencies, the present invention provides an electrode sheet which, through the setting of the opening portion, enables the soft electrode sheet close to the tongue portion to be straightly docked with the socket on the connector, thereby facilitating the installation and removal of the electrode sheet from the connector.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions:

[0006] The utility model discloses a disposable electrode sheet that is easy to assemble and disassemble. The electrode sheet includes a flexible circuit board, one end of the flexible circuit board in the length direction is a tongue, and a plurality of soldering pads are arranged at the end of the flexible circuit board in the length direction away from the tongue. The flexible circuit board between the soldering pad and the tongue is provided with a conductive circuit, and a conductor is bonded to the outer side of the soldering pad by conductive adhesive. The surface of the flexible circuit board outside the conductor is coated with a shielding layer by conductive adhesive, and the two are formed into an integral patch body, and the edge of the patch body between the tongue and the soldering pad is provided with an opening.

[0007] As a further embodiment of the present invention, the opening is a groove that penetrates the patch body in the thickness direction of the patch body, and the projection of the opening on a plane parallel to the thickness direction of the patch body is in a dovetail shape.

[0008] As a further embodiment of the present invention, the conductor is extended along the length direction of the flexible circuit board, and the length of the conductor located in the middle of the flexible circuit board is longer than the length of the conductor away from the middle of the flexible circuit board.

[0009] As a further embodiment of the present invention, the conductor protrudes outward from the shielding layer.

[0010] As a further embodiment of the present invention, the conductor is made of conductive rubber, conductive silica gel or conductive silicone material.

[0011] As a further embodiment of the present invention, the shielding layer covers the surface of the flexible circuit board from the middle of the tongue to the end of the tongue away from the pad.

[0012] As a further embodiment of the present invention, the negative electrode of the conductive circuit is grounded by being connected to the welding pad.

[0013] The beneficial effects of the utility model are:

[0014] The electrode sheet has openings on both sides of the patch body, which can form a fulcrum for the operator's fingers to pick up the electrode sheet when docking the electrode sheet with the connector. As a result, the soft electrode sheet close to the tongue can be docked with the socket on the connector in a straight shape after being picked up by the operator, which is convenient for the operator to dock the electrode sheet with the connector and can achieve the effect of quick connection between the electrode sheet and the connector. The design of the opening can also play a certain role in removing the electrode sheet from the connector. The easy installation and disassembly feature makes the electrode sheet better in terms of disposable performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0020] The utility model discloses a disposable electrode sheet which is convenient to assemble and disassemble. Figures 1-3 As shown in the figure, the electrode sheet includes a flexible circuit board 1, one end of the flexible circuit board 1 in the longitudinal direction is a tongue 2, and a plurality of pads 3 are arranged at the end of the flexible circuit board 1 in the longitudinal direction away from the tongue 2. The flexible circuit board 1 between the pad 3 and the tongue 2 is provided with a conductive circuit 4, and a conductor 5 is bonded to the outer side of the pad 3 by conductive glue. The surface of the flexible circuit board 1 outside the conductor 5 is coated with a shielding layer 6 by conductive glue, and the two are formed into an integral patch body 7, and the edge of the patch body 7 located between the tongue 2 and the pad 3 is provided with an opening 8.

[0021] Specifically, openings 8 are provided on both sides of the patch body 7 of the electrode sheet near the tongue 2. When the operator connects the electrode sheet to the connector, the operator's fingers are placed at the position of the openings 8, so that the operator's fingers form a fulcrum on the soft electrode sheet. After the operator picks up the part of the electrode sheet near the tongue 2 with his fingers, the part of the electrode sheet near the tongue 2 can be connected to the socket on the connector in a straight shape, which is convenient for the operator to connect the electrode sheet to the connector and can achieve the effect of quick connection between the electrode sheet and the connector. The design of the opening can also play a certain role in removing the electrode sheet from the connector. The convenient assembly and disassembly feature makes the electrode sheet better in terms of disposable performance.

[0022] In addition, the electrode sheet comes into contact with the patient's skin through the conductor 5, thereby guiding the action potential generated when the muscle is excited through the electrode sheet and recording the graph on the recording device of the nerve conduction velocity measuring instrument after amplification to be used as nerve conduction velocity data. The shielding layer 6 can prevent the flexible circuit board 1 on the electrode sheet from directly contacting the patient's skin, thereby preventing the flexible circuit board 1 from being contaminated and affecting the accuracy of the obtained data.

[0023] As one of the embodiments of the present invention, Figures 1-3 As shown in the figure, the opening portion 8 is a groove that penetrates the patch body 7 in the thickness direction of the patch body 7, and the projection shape of the opening portion 8 formed on a plane parallel to the thickness direction of the patch body 7 is dovetail-shaped.

[0024] Among them, the opening portion 8 is designed as a dovetail-shaped groove structure, and the contour of the opening portion 8 is close to the contour of the fingertip, which allows the operator's fingers to enter the opening portion 8 more easily, so that when the operator connects the electrode sheet with the connector, his fingers can form a fulcrum on the surfaces of both sides of the patch body 7, so that the part of the electrode sheet close to the tongue 2 is in a straight state.

[0025] As one of the embodiments of the present invention, Figure 1 and Figure 2 As shown in the figure, the conductor 5 is extended along the length direction of the flexible circuit board 1 , and the length of the conductor 5 located in the middle of the flexible circuit board 1 is longer than the length of the conductor 5 away from the middle of the flexible circuit board 1 .

[0026] Among them, the arrangement of the conductor 5 along the surface of the flexible circuit board 1 can prevent the electrode sheet from being contaminated by excessive contact with the human skin after being attached to the human skin. At the same time, it can also form contact with the human skin surface as much as possible in the length direction of the electrode sheet, ensuring that the conductor 5 can conduct the action potential generated when the muscle is excited to the flexible circuit board 1.

[0027] As one of the embodiments of the present invention, Figure 2 As shown, the conductor 5 protrudes outward from the shielding layer 6.

[0028] Among them, the conductor 5 protruding outward from the shielding layer 6 can ensure that the electrode sheet can maintain contact with the surface of the human skin after being attached to the human skin, and further ensure that the conductor 5 can conduct the action potential generated when the muscle is excited to the flexible circuit board 1.

[0029] As one of the embodiments of the present invention, Figure 1 As shown, the conductor 5 is made of conductive rubber, conductive silica gel or conductive silicone material.

[0030] Among them, the conductor 5 can not only realize the conductive function, but also has a good structural maintenance ability when subjected to external force, and is less likely to be damaged, ensuring that it can work stably to realize the function of transmitting the action potential generated when the muscle is excited to the flexible circuit board 1.

[0031] As one of the embodiments of the present invention, Figure 2 and Figure 3 As shown in the figure, the shielding layer 6 covers the surface of the flexible circuit board 1 from the middle of the tongue 2 to the end of the tongue 2 away from the pad 3.

[0032] Among them, since a part of the tongue 2 needs to be connected to the connector, the shielding layer 6 does not cover this part of the tongue 2, and the surface of the flexible circuit board 1 covered by the shielding layer 6 includes the front and back of the flexible circuit board 1, thereby preventing the flexible circuit board 1 from being contaminated when the electrode is pasted on the patient's skin, the operator touches the electrode with his hands, or is exposed to the external environment.

[0033] As one of the embodiments of the present invention, Figure 1 As shown, the negative electrode of the conductive circuit 4 is grounded by being connected to the pad 3 .

[0034] The purpose of the negative electrode of the conductive circuit 4 being the ground electrode is to keep the voltage level on the patient's body within an acceptable range.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
