[0033] A plurality of conductive connecting plates 5, the first end of each of the plurality of conductive connecting plates 5 passes through the bottom plate and is connected with the plurality of electrode circuits 3 one by one, the second end of each of the plurality of conductive connecting plates 5 is located in the inside of the clamping groove structure 11 after being bent respectively and forms a spring arm structure extending in the direction away from the bottom plate with elastic force;

[0034] Among them, the end of the second end of each of the plurality of conductive connecting plates 5 is provided with a conductive protruding structure 51, the positioning stop point in the process of inserting the main machine 6 into the clamping groove structure 11 is opposite to the maximum elastic potential energy storage point of the spring arm structure, so that the plurality of conductive protruding structures 51 and the plurality of conductive ends of the main machine 6 correspond one by one.

[0035] The connecting structure provided by the embodiments of the present application can collect bioelectricity generated by the heart of the to-be-measured living body by using the plurality of electrode circuits 3 and the plurality of electrodes 4 arranged on the flexible patch 2, after the main machine 6 is connected with the positioning and locking member 1 in the form of lateral insertion, the conductive end of the main machine 6 can be electrically connected with the conductive connecting plate 5, so that the bioelectricity is finally guided to the main machine 6 through the conductive connecting plate 5, the main machine 6 can analyze the collected bioelectricity, and finally obtain the electrocardiogram monitoring result.

[0036] Meanwhile, the conductive connecting plate 5 provided by the structure is located in the card slot structure 11 to form an elastic arm structure, which can be deformed by extrusion after the host 6 is connected with the card slot structure 11, so as to provide an elastic restoring force to the host 6, and under the action of the elastic restoring force, the conductive connecting plate 5 can be guaranteed to be in close contact with the conductive end of the host 6, so as to obtain good electrical connection stability, and even when the connection between the host 6 and the card slot structure 11 is loose, the electrical circuit can still be guaranteed to be smooth. The conductive connecting plate can exist as an independent component and be connected with the electrode circuit by welding or the like. Alternatively, the conductive connecting plate can be formed at the distal end of the electrode circuit in the form of an extended electrode circuit.

[0037] In addition, the end of each conductive connecting plate 5 is provided with a conductive protruding structure 51, which can make the positioning stop point in the process of inserting the host 6 opposite to the maximum elastic potential storage point of the elastic arm structure, so as to guarantee that the elastic arm structure can provide the maximum elastic restoring force to the conductive end of the host 6, thereby achieving the purpose of further improving the electrical connection stability between each conductive connecting plate 5 and the conductive end of the host 6.

[0038] The positioning and locking member 1 provided by the embodiment of the present application is used as a connecting piece between the host 6 and the flexible patch 2, and the positioning and locking member 1 is in the form of a laterally arranged socket. When the host 6 needs to be connected with the flexible patch 2, the user only needs to hold the host 6 and then insert the host 6 into the card slot in the positioning and locking member 1 through the socket, so as to realize the clamping connection of the host 6. In order to further improve the structural stability of the host 6 after being connected with the positioning and locking member 1, the bottom plate of the positioning and locking member 1 can be provided with a locking tongue 12 at one end of the socket.

The number of the electrode circuit 3 and the electrode 4 can be determined according to actual needs.

[0041] Since the conductive connecting plate 5 provided by the present application mainly adopts elastic restoring force to realize close connection with the conductive end of the host 6, in order to prevent interference between the conductive connecting plates 5, the embodiment of the present application can provide a plurality of conductive connecting plates 5, including three, and the elastic arm structures formed by the three conductive connecting plates 5 are independently arranged. The three conductive connecting plates 5 can be connected one by one with the three electrode circuits 3, and the independent mode of each conductive connecting plate 5 is adopted, so that the elastic restoring force generated by each conductive connecting plate 5 is independent of each other, and there is no interference between them, achieving the purpose of providing stable electrical connection.

[0042] The conductive protruding structure 51 provided by the embodiment of the present application can be used as a conductive contact, and at the same time, the conductive protruding structure 51 is arranged at the end and cooperates with the sliding positioning structure, so that the point with the maximum elastic force is just at the stop point of the sliding positioning during the connection process, thereby improving the stability of the electrical connection. In order to prevent the conductive protruding structure 51 from affecting the normal insertion of the host 6 during the sliding insertion of the host 6, the embodiment of the present application can provide that the conductive protruding structure 51 has a spherical external contour structure. The conductive protruding structure 51 with the spherical external contour structure can ensure that the initial contact position of the conductive protruding structure 51 and the host 6 forms an arc transition, thereby facilitating the insertion of the host 6.

[0043] In order to improve the conductive performance of the conductive protruding structure 51, the embodiment of the present application can also provide that the surface of the conductive protruding structure 51 is provided with a plating layer for improving the conductive capacity. Further, the material of the plating layer includes any one of copper, silver and gold.

[0044] In summary, the connecting structure provided by the application has simple and reasonable structure, is convenient to install and use, and has low manufacturing cost. That is, the connecting structure can realize quick connection and disconnection of the host and the flexible patch, and after the host is connected with the positioning and locking member, the elastic arm and the conductive protrusion structure at the end of the elastic arm jointly act, so that the point with the maximum elastic force is just at the stop point of the sliding positioning in the connection process, and the conductive connecting plate can be tightly abutted with the conductive end of the host, so as to improve the stability of the electrical connection.

[0045] The embodiment of the application can also provide a portable electrocardiogram detector, which comprises a flexible patch body, a host, and the connecting structure.

The adhesive layer can be protected by the release layer, and the adhesive effect of the adhesive layer can be prevented from being lost or weakened during transportation after leaving the factory. When the flexible patch needs to be attached, the release layer is separated from the adhesive layer, and then the flexible patch is attached to the skin surface of the to-be-detected living body, so as to ensure the firmness of the attachment of the flexible patch and reduce the possibility of relative displacement of the flexible patch and the human skin during movement.

[0048] Further, the release layer comprises one of a paper-based single-sided silicon release layer or a PET-based single-sided silicon release layer. The paper-based single-sided silicon release layer or the PET-based single-sided silicon release layer can stick to the prepreg, but can also easily separate the two; when the ambient temperature and humidity change, the length and width of the release paper can remain unchanged, and the release paper will not wrinkle to cause the prepreg to wrinkle, and the release paper has sufficient density to prevent moisture from entering the prepreg.
