In the prior art, some bendable electrodes can be bent only according to preset folds, and cannot be bent at will according to the body shape of a patient, so that wearing comfort of the wearable electrode cannot be truly improved.

In the above technical solution, the metal sheet 101 may be bent arbitrarily according to the shape of the patient's body surface, the cushion 102 may be bent together with the metal sheet 101, the hard electrodes 104 in the plurality of through holes 103 uniformly distributed in the cushion 102 may enable electric energy to be uniformly and fully applied to the metal sheet 101, the soft metal layer 106 between the cushion 102 and the metal sheet 101 is closely attached to the surface of the metal sheet 101 facing the cushion 102, when the metal sheet 101 is bent, the soft metal layer 106 may provide sufficient flexibility for the metal sheet 101, and meanwhile, increase the bending radius of the metal sheet 101 when the metal sheet 101 is bent, so as to prevent the metal sheet 101 from being broken due to the sharp angle of the metal sheet 101.

Further, the soft metal layer 106 is further used to connect the metal sheet 101 and the hard electrode 104 located in the through hole 103 of the soft pad 102, when the metal sheet 101 and the soft metal layer 106 are bent together, the soft pad 102 is bent along with the soft pad, at this time, the hard electrode 104 in the through hole 103 of the soft pad 102 is pulled or pushed by the soft metal layer 106, and the relative position of the soft pad 102 in the through hole 103 is changed, at this time, the soft pad 102 can provide a buffer for the hard electrode 104, so as to prevent the hard electrode 104 and the first conductive wire 105 connected with the hard electrode 104 from being squeezed or collided, resulting in the connection damage between the hard electrode 104 and the first conductive wire 105.

Further preferably, the thickness of the soft metal layer 106 may be greater than the thickness of the metal sheet 101. In this embodiment, the soft metal layer 106 having a thickness greater than that of the metal sheet 101 provides sufficient flexibility to the metal sheet 101 and sufficient support to prevent the metal sheet 101 from being broken when the metal sheet 101 is bent.

As a preferred embodiment, the material of the soft metal layer 106 may include indium or indium tin alloy. In this technical solution, the indium or the indium-tin alloy is soft metal and has ductility, when the thickness of the soft metal layer 106 is smaller, the soft metal layer can be bent at will, and the indium or the indium-tin alloy has a lower melting point, so that the liquid indium or the indium-tin alloy can be filled between the metal sheet 101 and the soft pad 102 during processing, the liquid indium or the indium-tin alloy has good fluidity and caulking effect, the liquid indium or the indium-tin alloy can fully flow into each through hole 103 of the soft pad 102 to fully contact with the hard electrode 104, and a welding effect can be generated between the indium or the indium-tin alloy and the metal sheet 101 and the hard electrode 104 after solidification by adopting a welding assisting measure on one surface of the metal sheet 101 facing the soft pad 102 and the surface of the hard electrode 104. Preferably, the soldering means may employ a flux.

As a preferred embodiment, the metal sheet 101 may be made of copper or aluminum.

As a preferred embodiment, the hard electrode 104 may be a metal ball or a metal pin. In this technical scheme, the hard electrode 104 can be realized by adopting a metal ball or a metal pin with a shape matched with the through hole 103, so that the hard electrode 104 has the capability of moving along the length direction of the through hole in the through hole 103, when the soft pad 102 is deformed due to bending, the through hole 103 deforms along with the deformation of the soft pad 102, and the hard electrode 104 which can move along the length direction of the through hole 103 can be better adapted to the deformation of the through hole 103.

Further preferably, the hard electrode 104 is made of copper or aluminum.

Further preferably, the cushion 102 is made of a heat-resistant elastic material, such as a heat-resistant rubber material.

On this basis, it is further preferable that the cross section of the through hole 103 may be circular or elliptical.

Further preferably, the distance between the adjacent through holes 103 may be larger than the diameter of the through holes 103, in this technical solution, the distance between the adjacent through holes 103 is larger than the diameter of the through holes 103, so that the resistance of the hard electrode 104 in each through hole 103 to the bending of the cushion 102 can be reduced.

In the above technical solution, the wearable electrode is a sheet-like body as a whole, the size can be predefined according to the size of the patient, and the specific definition mode of the size is described in the prior art, and is not a point of interest of the patient, so that the description is omitted.

Further, the method may further include:

In this technical solution, the soft metal layer 106 is directly connected to the soft metal layer 106 through an independent second wire 107, so that the soft metal layer 106 and each hard electrode 104 can be independently connected, in an alternative embodiment, each hard electrode 104 can be connected to the soft metal layer 106 through the first wire 105 through a selection circuit, and the soft metal layer 106 can be connected to the soft metal layer 106 through the second wire 107 through the first wire 105, and the selection circuit can selectively connect or disconnect each hard electrode 104, or the soft metal layer 106, so that the conduction condition between each hard electrode 105 and the soft metal layer 106 can be tested. If a pair of hard electrodes 104 is selected to be conducted by a selection circuit, it is tested whether the pair of hard electrodes 104 is conducted, and according to this method, it is tested whether the connection between each pair of hard electrodes 104 is normal because all hard electrodes 104 are conducted by the soft metal layer 106.

Further, all the hard electrodes 104 may be disconnected by a selection circuit, and only the connection with the soft metal layer 106 may be maintained, so that the soft metal layer 106 and the metal sheet 101 may be used as an independent electrode for detecting electrocardiographic data of a patient.

Further preferably, the method further comprises the following steps:

If the selection circuit can select all the hard electrodes 104 that are disconnected from the first wire 105 and conduct the soft metal layer 106 through the second wire 107 and the metal sheet 101 through the third wire 108, it is tested whether the connection between the soft metal layer 106 and the metal sheet 101 is damaged. It is also possible to disconnect all the hard electrodes 104 by a selection circuit and to disconnect the soft metal layer 106, only keeping the connection to the foil 101, so that the foil 101 is used as an independent electrode for detecting the electrocardiographic data of the patient.

The existing automatic defibrillator usually leaves an insulating area in an electrode sheet, a small metal area is embedded in the insulating area to serve as an electrode for detecting the electrocardiographic data of a patient, the embedded electrode is used for detecting the electrocardiographic data of the patient, as the electrode is embedded in a discharge electrode sheet of the automatic defibrillator, the area of the electrode for detecting the electrocardiographic data of the patient is small so as not to influence the discharge of the electrode sheet, and therefore a required detection position cannot be accurately aligned, experienced personnel are required to be required for accurate alignment, and in the case of a wearable automatic defibrillator used by non-professional personnel, the embedded electrode with a small area is easy to move along with the body movement of the patient when worn on the patient, so that the wearable automatic defibrillator cannot accurately acquire the electrocardiographic data of the patient, and rescue time is missed. According to the technical scheme, the area of the electrode for detecting the electrocardiographic data of the patient is completely the same as that of the wearable electrode slice, so that the defects that the embedded electrode is small in area and difficult to align with the position and the position moves due to the body movement of the patient in the prior art are avoided.

In this technical solution, grooves are provided on both the inner and outer sides of one surface of the soft cover 110 corresponding to the cushion 102, so that the soft cover 110 can be bent more conveniently.

In the above-described embodiments, the larger the number of the hard electrodes 104, the smaller the area of the single hard electrode 104 projected on the metal sheet 101, and therefore, when more hard electrodes 104 are provided, the smaller the cross-sectional area of the single hard electrode 104 parallel to the opening of the through hole 103, that is, the smaller the resistance of the single hard electrode 104 to bending of the whole cushion 102, that is, the more hard electrodes 104 are provided, the greater the bending freedom of the cushion 102.
