Abstract

Claims (18)

1. An electrode plate for use in cardiac defibrillation, the electrode plate comprising:

a hermetic shell having an inflation port and an overflow aperture, the overflow aperture provided in an exposed surface of the hermetic shell, wherein the exposed surface has electrical conductivity;

a capsule disposed in the hermetic shell, the capsule defining a cavity for storage of a conductive paste therein, the cavity defining an inlet orifice and an outlet orifice, the overflow aperture disposed at the outlet orifice, the cavity isolated from a hollow internal space of the hermetic shell; and

a sealing structure comprising a sealing component and a force applying component, the sealing component disposed at the overflow aperture, the sealing component configured to close the overflow aperture and the outlet orifice when the hermetic shell is not inflated, the force applying component disposed on the hermetic shell and connected to the sealing component after being inserted into the capsule through the inlet orifice, the force applying component configured to pull the sealing component when the hermetic shell is inflated and expanded, so that the overflow aperture and the outlet orifice are opened and communicated with each other.

2. The electrode plate according to claim 1 , wherein part of the force applying component is disposed out of the hermetic shell and the rest of the force applying component is inserted into the capsule through the inlet orifice and threadedly connected to the sealing component.

3. The electrode plate according to claim 2 , wherein the overflow aperture is an internally threaded bore, the sealing component is inserted into the internally threaded bore and threadedly connected to the hermetic shell in a sealing manner.

4. The electrode plate according to claim 3 , wherein an inner wall of the hermetic shell is provided with a threaded boss providing the internally threaded bore, wherein the threaded boss extends through the outlet orifice into the interior of the capsule, and wherein the capsule is connected to the threaded boss in a sealing manner.

5. The electrode plate according to claim 2 , wherein the sealing component comprises a barrier sheet and a connecting member provided on the barrier sheet, the barrier sheet provided on the hermetic shell so as to cover the overflow aperture, wherein the rest of the force applying component is inserted through the inlet orifice into the interior of the capsule and connected to the connecting member.

6. The electrode plate according to claim 5 , wherein the connecting member is a threaded boss extending through the outlet orifice into the interior of the capsule and defining a blind threaded bore, wherein the rest of the force applying component is inserted through the inlet orifice into the interior of the capsule and threadedly connected to the threaded boss in a sealing manner.

7. The electrode plate according to claim 1 , wherein the hermetic shell comprises a defibrillation panel and a rear shell member, which are coupled together to form an enclosed casing, the defibrillation panel providing the exposed surface, the defibrillation panel having material strength that is higher than material strength of the rear shell member, the rear shell member configured to be deformable as a result of filling a gas into the hermetic shell through the inflation port.

8. The electrode plate according to claim 7 , wherein the defibrillation panel comprises a conductive panel and a front shell member, wherein both the front shell member and the rear shell member are insulators, and the conductive panel is a conductor, wherein the front shell member and the rear shell member are coupled together to form the enclosed casing, wherein the conductive panel provides the exposed surface and is disposed on the side of the front shell member away from the rear shell member, wherein the capsule is disposed within the enclosed casing and is disposed on the front shell member, and wherein material strength of the front shell member is higher than the material strength of the rear shell member.

9. The electrode plate according to claim 8 , wherein the overflow aperture is disposed in the front shell member, the sealing component is disposed on the conductive panel so as to cover the overflow aperture.

10. The electrode plate according to claim 7 , wherein an inner surface of the rear shell member is provided thereon with a bump protruding toward the defibrillation panel and/or annular corrugations.

11. The electrode plate according to claim 7 , wherein an inner surface of the rear shell member is provided thereon with a protrusion configured for abutment of the capsule thereagainst.

12. The electrode plate according to claim 1 , wherein the capsule comprises a body that defines the cavity and a collar extending outward from the body, the collar defining a hollow channel acting as the outlet orifice, the collar provided with a footing support which extends outward, extends around an axis of the collar and is provided on an inner wall of the hermetic shell, thus securing the capsule.

13. The electrode plate according to claim 1 , wherein the sealing component and the overflow aperture are configured so that when a pulling force acting on the sealing component increases to a predetermined value, the sealing component is able to be separated from the overflow aperture, allowing the conductive paste stored in the cavity to flow out of the outlet orifice and flow through the overflow aperture onto the exposed surface.

14. A wearable defibrillation device, comprising a vest, and provided on the vest, a sensing electrode, a host and an airbag, the wearable defibrillation device further comprising the electrode plate as defined in claim 1 , which is provided on the vest.

15. The wearable defibrillation device according to claim 14 , wherein the electrode plate is configured as the airbag.
