Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention discloses a defibrillation electrode sheet, as shown in Figure 1, the defibrillation electrode sheet includes:

The first electrode sheet 101 and the second electrode sheet 102 for attaching to the skin surface of the target object, the first electrode sheet 101 and the second electrode sheet 102 are connected by a lead wire 103, and the first electrode sheet 101 is provided with a The electrodes 104 for collecting ECG signals of the target objects RA, LA, RL and LL, and the first electrode sheet 101 and the second electrode sheet 102 are respectively provided with defibrillation electrodes 105 for releasing defibrillation pulse current to the target objects.

In this embodiment, a defibrillation electrode pad is provided, which specifically includes two electrode pads for attaching to the skin surface of the target subject, that is, the first electrode pad 101 and the second electrode pad 102, and The first electrode sheet 101 and the second electrode sheet 102 are respectively provided with a defibrillation electrode 105 for releasing a defibrillation pulse current to the target object, and the first electrode sheet 101 is provided with a defibrillation electrode 105 for collecting the target object RA (Right Arm) , LA (Left Arm), RL (Right Leg) and LL (Left Leg) electrocardiographic acquisition electrodes 104, that is, respectively corresponding to the target object's right arm, left arm, right leg and left leg electrocardiographic signals The collection electrode 104. As shown in Figure 2, when the operator is using the defibrillation electrode sheet, the target object only needs to place the first electrode sheet 101, that is, the first electrode sheet 101 equipped with the acquisition electrode 104 above the sternum of the target object , place the second electrode piece 102 at the junction of the fifth intercostal space on the left side of the target subject and the midaxillary line, at this time, the first electrode piece 101 and the second electrode piece 102 can form a defibrillation electrode piece group, thus The collected lead ECG signal of the target object can release the corresponding defibrillation pulse current to the target object to terminate the ventricular fibrillation of the target object, eliminate the arrhythmia of the target object, and restore the heart of the target object to sinus rhythm .

It should be noted that the target object here may be a patient, or other animal bodies that need to be measured. Moreover, here, four sets of collecting electrodes 104 may be set on the first electrode sheet 101 to collect ECG signals at the target objects RA, LA, RL, and LL, respectively, wherein each set of collecting electrodes may be provided with One collection electrode or multiple collection electrodes.

As a preferred embodiment, the collection electrode 104 can be set in a circular, square or elliptical shape. Of course, the collection electrode 104 can also be set in other shapes, which is not specifically limited here.

Specifically, in practical applications, the lateral distance of the four collection electrodes 104 on the rectangular electrode sheet can be set to 5.5 cm to 6.5 cm, and the longitudinal distance of the four collection electrodes 104 on the rectangular electrode sheet can be set to 8.5 cm to 9.5 cm. . Of course, here is just a better setting method, and in actual application, specific adjustments can be made according to the actual physical condition of the target object, and no specific limitation is made here. In addition, in order to further improve the target object's experience of using the defibrillation electrode pads, text or picture descriptions can also be provided on the side of the first electrode pad 101 facing away from the target object to assist the target object to place the defibrillation electrode pads. in the correct position on the body.

The electrode sheet is provided with electrodes for collecting ECG signals of target objects RA, LA, RL and LL. When the operator uses defibrillation electrodes, he only needs to place the first electrode above the sternum of the target object, and place the second electrode at the junction of the fifth rib on the left side of the target and the midaxillary line. The ECG signals of the target object can be subtracted two by two to obtain the ECG signals of multiple leads of the target object, thereby eliminating the need to attach multiple defibrillation electrodes on the target object in the prior art Trouble. Therefore, through the collected ECG signals of multiple leads, the defibrillation electrodes on the first electrode sheet and the second electrode sheet on the defibrillation electrode sheet can be used to perform better defibrillation on the target object, and through this defibrillation electrode Trembling electrodes can be more helpful for doctors to distinguish the target object's heart rate.

Glue, in order to utilize the function that the conductive gel has viscosity and conductivity, prevent the defibrillation electrode sheet from falling off the collection electrode 104 and the defibrillation electrode 105 in the process of collecting the ECG signal of the target object, so that the collected ECG signals are clearer and more recognizable. Similarly, in order to better fit the defibrillation electrode 105 to the skin of the target object, conductive gel can also be set on the defibrillation electrode 105, so that the defibrillation electrode 105 can better release the defibrillation pulse current .

Based on the above-mentioned embodiment, this embodiment is a specific description and optimization of the previous embodiment.
