Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical external defibrillation equipment, and particularly relates to an external defibrillation device. BACKGROUND

[0002] An external defibrillator (AED) is a medical device used to restore normal rhythm of the heart by electric shock when the heart stops beating; However, in actual application, due to the hair on the skin of the patient or skin diseases, the electrode may not be in good contact with the skin, thereby making the electric shock effect poor; and the electric shock energy cannot be fully transmitted to the heart, affecting the resuscitation effect. Therefore, in order to improve the electric conduction efficiency, the present application provides an external defibrillation device. SUMMARY

[0003] In view of the defects in the prior art, the present application provides an external defibrillation device which can improve the conduction efficiency and improve the resuscitation effect of the heart.

[0004] The external defibrillation device provided by the present application comprises: a defibrillation main body for providing a power supply; and an electrode main body electrically connected with the defibrillation main body; the electrode main body comprises a handheld main body and an electrode assembly; the electrode assembly is installed on the handheld main body and comprises an electrode piece and a conduction piece; the electrode piece is installed on the handheld main body and is used for generating electric shock defibrillation; the conduction piece is provided in multiple places and is spaced apart and uniformly installed on the handheld main body; the handheld main body is provided with a mounting liquid cavity, and an electrically conductive solution is sealed and filled in the mounting liquid cavity; the conduction piece comprises a liquid pipe, a pressing conduit and a spring; the liquid pipe is in communication with the mounting liquid cavity, one end of the pressing conduit is installed in the liquid pipe, and the other end of the pressing conduit extends outward; the spring is arranged in the liquid pipe and is installed on the pressing conduit, wherein one end of the spring is fixedly installed outside the liquid pipe, and the other end of the spring is connected with the pressing conduit.

[0005] Further, the conduction piece further comprises a sealing ring, the pressing conduit is further provided with an abutment section, and the abutment section is arranged in the direction of the liquid pipe; the sealing ring is fixedly installed on the abutment section, and the sealing ring is in sealing abutment with the pipe opening of the liquid pipe. In actual application, the purpose of this design is to realize sealing, so that the sealing ring can effectively abut at the pipe opening of the liquid pipe when the electric shock is not pressed, thereby effectively realizing the sealing effect.

[0006] Furthermore, the electrode body also includes a sealing ring; the sealing ring is mounted on the handheld body and located at the edge of the handheld body. In actual use, the purpose of this design is to prevent the conductive solution from overflowing during the pressing and shocking process; thus, it can facilitate the conduction of electricity to the electrode.

[0007] Furthermore, the electrode assembly includes a mounting patch, which is detachably mounted on the handheld body. In actual use, the detachable design adopted by this design effectively facilitates the realization of one person using one device.

[0008] Furthermore, the mounting patch is provided with at least one shield scale, and the shield scales are evenly distributed on the mounting patch, wherein one end of the shield scale is located on the surface of the mounting patch, and the other end of the shield scale extends outward. In actual use, the purpose of this design is to enhance the contact effect. Through the shield scale design similar to shark skin, during the contact process with the skin, first of all, due to the direct contact of the shield scales with the skin, a deepening and extending progressive effect is achieved; and the direct contact of multiple shield scales also achieves distributed contact. The effect of its multi-point contact replaces the design of the traditional planar electrode plate, so that in the contact with the patient's skin, point contact is achieved from plane contact; the electrode is changed from surface to point, and the multi-point contact design can penetrate deeper into the skin; this can ensure the electric shock effect, and at the same time, the electric shock deep into the skin can also facilitate the full transfer of electric shock energy to the heart.

In actual use, in order to achieve electric shock, the defibrillation electrodes are mounted on the shield scale to achieve an efficient electrode effect.

[0010] Furthermore, the electrode assembly also includes a dry electrode sheet, of which multiple sheets are provided and mounted one by one on the other side of the shield scale. In actual use, the purpose of this design is to reduce the accumulation of conductive solution between the shield scale and the mounting patch; in this way, it can ensure that the electric shock is concentrated on the patient's skin during the electric shock process. Of course, in actual operation, the dry electrode generates heat when energized, thereby evaporating the liquid accumulated between the shield scale and the mounting patch. In this way, the generated vapor gathers in the handheld body between the sealing rings, which can ensure the electric shock effect.

[0011] Furthermore, the mounting patch is provided with a liquid guide hole, and the liquid guide hole is close to the direction of the defibrillation electrode; wherein the pressing tube is arranged in the liquid guide hole and extends outward. In actual use, the purpose of this design is to facilitate the conductive solution to overflow more easily in the direction close to the defibrillation electrode.

[0012] From the above technical solutions, the application provides a beneficial effect of the external defibrillation device: In actual work, the design uses an increase in conductive solution as a conductive medium, which can effectively improve the conductive efficiency, and then facilitate the conduction of electric shock to the heart part. Among them, the design of pressing automatic liquid outlet is adopted, which realizes the outflow of conductive solution during use, and can be stopped when not in use, which can greatly save the conductive solution. In the actual operation process, the conductive solution is prepared by using salt water with a certain concentration. In this way, high efficiency and simple operation are realized.

[0017] The embodiment is basically as shown in the accompanying drawings Figures 1 to 5As shown: like Figures 1-5 As shown, the external defibrillator provided in this embodiment can improve conduction efficiency and enhance cardiac resuscitation effect.

[0018] The present invention provides an external defibrillator, comprising: a defibrillator body 1, the defibrillator body 1 being used to provide power; and an electrode body 2, the electrode body being electrically connected to the defibrillator body 1; the electrode body comprising a handheld body 21 and an electrode assembly 22; the electrode assembly 22 being mounted on the handheld body 21, the electrode assembly 22 comprising an electrode member 221 and a conductive member 222, the electrode member 221 being mounted on the handheld body 21 and being used to generate electric shock defibrillation; the conductive member 222 being provided in a plurality of locations, being spaced apart, and being evenly distributed on the handheld body 21; the handheld body 21 being provided with a mounting liquid chamber 211 , and the conductive solution 200 is sealed in the installation liquid cavity 211; the conductive member 222 includes a liquid tube 2221, a pressing tube 2222 and a spring 2223; the liquid tube 2221 is communicated with the installation liquid cavity 211, one end of the pressing tube 2222 is installed in the liquid tube 2221, and the other end of the pressing tube 2222 extends outward; the spring 2223 is arranged in the liquid tube 2221 and installed on the pressing tube 2222, wherein one end of the spring 2223 is fixedly installed outside the liquid tube 2221, and the other end of the spring 2223 is connected to the pressing tube 2222. In actual work, the design adopts the addition of conductive solution 200 as the conductive medium, which can effectively increase the conductive efficiency and facilitate the conduction of electric shock to the heart. Among them, the design adopts the automatic liquid discharge design of pressing to realize the discharge of conductive solution 200 during use, and it can be disused when not in use. In this way, the conductive solution 200 can be greatly saved. In the actual operation process, the conductive solution 200 is prepared with saline with a certain concentration. In this way, high efficiency, practicality and simple operation are achieved.

[0019] In this embodiment, to enhance the sealing effect of the conductive solution 200, the conductive member 222 further includes a sealing ring 2224. The pressing tube 2222 also has an abutment section 2201, which is positioned within the liquid tube 2221. The sealing ring 2224 is fixedly mounted on the abutment section 2201 and sealably abuts the opening of the liquid tube 2221. In practice, this design is intended to achieve a seal, ensuring that when no pressing shock is applied, the sealing ring 2224 effectively abuts the opening of the liquid tube 2221, effectively achieving a sealing effect.

[0020] To prevent the conductive solution 200 from overflowing during use and to keep it contained within the handheld body 21, the electrode body 2 in this embodiment also includes a sealing ring 23. The sealing ring 23 is mounted on the handheld body 21 and located at the edge of the handheld body 21. In practice, this design prevents the conductive solution 200 from overflowing during the electric shock process, thereby facilitating electrical conduction to the electrode element 221.

[0021] In this embodiment, the electrode assembly 22 includes a mounting patch 224, and the mounting patch 224 is detachably mounted on the handheld body 21. In actual use, the detachable design adopted by this design effectively facilitates the realization of one person using one device.

[0022] In order to facilitate the realization of more efficient conduction efficiency, in this embodiment, the mounting patch 224 is provided with at least one shield scale 2241, and the shield scales 2241 are evenly distributed on the mounting patch 224, wherein one end of the shield scale 2241 is located on the surface of the mounting patch 224, and the other end of the shield scale 2241 extends outward. In actual use, the purpose of this design is to enhance the contact effect. Through the design of the shield scales 2241 similar to shark skin, in the process of contact with the skin, first of all, due to the direct contact of the shield scales 2241 with the skin, a deepening, extending and progressive effect is achieved; and the direct contact of multiple shield scales 2241 also achieves distributed contact. The effect of its multi-point contact replaces the design of the traditional planar electrode plate, so that in the contact with the patient's skin, point contact is achieved from planar contact; the electrode is changed from surface to point, and the multi-point contact design can penetrate deeper into the skin; in this way, the electric shock effect can be guaranteed, and at the same time, the electric shock deep into the skin can also facilitate the full transfer of electric shock energy to the heart.

[0023] In this embodiment, the electrode member 221 includes a defibrillation electrode 2211. Multiple defibrillation electrodes 2211 are provided and mounted one on each side of the shield scale 2241, away from the mounting patch 224. In actual use, to achieve an electric shock, the defibrillation electrodes 2211 are mounted on the shield scale 2241 to achieve an efficient electrode effect.

[0024] At the same time, in order to reduce liquid accumulation, in this embodiment, the electrode assembly 22 also includes a dry electrode sheet 226. There are multiple dry electrode sheets 226, and each of them is installed one by one on the other side of the shield scale 2241. In actual use, the purpose of this design is to reduce the accumulation of conductive solution 200 between the shield scale 2241 and the mounting patch 224; in this way, it can be ensured that the electric shock is concentrated on the patient's skin during the electric shock process. Of course, in actual operation, the dry electrode sheet 226 generates heat after being energized, thereby evaporating the liquid accumulated between the shield scale 2241 and the mounting patch 224. In this way, the vapor generated by it gathers in the handheld body 21 between the sealing ring 23, which can ensure the electric shock effect.

[0025] To further facilitate the conduction of the conductive solution 200, in this embodiment, the mounting patch 224 is provided with a liquid guide hole 2242, which is located near the defibrillation electrode 2211. The pressing tube 2222 is located within the liquid guide hole 2242 and extends outward. In practice, this design facilitates the conductive solution 200 to more easily overflow near the defibrillation electrode 2211.

It can effectively achieve high conduction efficiency, so that electricity can fully enter the heart. In this way, the effect of cardiac resuscitation can be improved. Therefore, the device is suitable for industry promotion.
