Dry-type defibrillation electrode

Abstract

The invention discloses a dry-type defibrillation electrode. The dry-type defibrillation electrode comprises actuators, limiters, energy storage devices, a storage bin and a treatment electrode, wherein the actuators are displacement output devices, are fixed on the outer surface of the storage bin and are reliably connected with the limiters, the treatment electrode is located in the storage bin, and the energy storage devices are located between the inner surface of the storage bin and the treatment electrode; the limiters comprise limiting inverted buckles, and part of the limiters penetrates through a surface opening of the storage bin and extends into the storage bin to form the limiting inverted buckles; the position of the treatment electrode is lower than that of the limiting inverted buckles; and the edges of the limiting inverted buckles are positioned in a projection plane in the movement direction of the treatment electrode. When defibrillation is implemented, the actuators generate displacement and enable the limiters to slide outwards, and when the edges of the limiting inverted buckles completely leave the projection plane in the movement direction of the treatment electrode, the energy storage devices release compression energy, so that a flexible pole piece is attached to the skin. No conductive medium is needed, and the production and use cost is reduced. The problems of shelf life and skin allergy caused by the conductive medium, difficulty in removing the residual conductive medium after use and the like are solved, and the system reliability is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a dry defibrillation electrode. Background technique [0002] Wearable automatic external defibrillator (WCD) can be effectively used for short-term risk prevention and ventricular fibrillation treatment of patients with high risk of sudden cardiac death in clinical practice. WCD equipment has monitoring and defibrillation functions, which ensures the life safety of patients with potential sudden cardiac death, and also allows doctors and nurses to better follow up with patients and provide rescue support when necessary. [0003] In the patent CN209333020U, an electrode system is described, which uses a fluid pump to generate pressure to release the conductive gel in the gel deployment container to the body of the subject. [0004] In the patent CN212631456U, a defibrillation ejection device is described. Under the control of the electromagnetic valve, the liquid com...

Problems solved by technology

[0005] Both of the above two patents form a conductive path between the patient’s body and the WCD device by deploying a conductive medium, but the method of spraying the medium has the following problems: the product design is complicated and the overall cost is high; the built-in conductive medium needs to pay attention to its shelf life Problems; contact between conductive media and human skin can easily cause skin allergies in patients; it is difficult to remove residual conductive media after use
