[0002] An automatic external defibrillator (AED), also known as an electric cardioverter, consists of a charge / discharge circuit, a control circuit, a power supply, and electrode plates. It uses current pulses to shock the heart and restore sinus rhythm. It is an extremely important emergency device in clinical practice and an important means of treating severe cardiac rhythm diseases. According to clinical operation requirements, when performing cardiac defibrillation, it is necessary to apply defibrillator cream (conductive paste or conductive liquid) to the electric shock, which can improve the conductivity of the electrode and is extremely important to ensure the defibrillation effect.

[0003] At present, in the process of applying defibrillator cream, the staff usually manually applies the cream on the electrode, and then the two electrodes are placed opposite to each other and rubbed against each other to ensure the uniformity of the paste coating and to make the paste cover the entire electrode as much as possible. However, the fullness of the coating in this way mainly depends on the operator's control, which has a certain risk of error. At the same time, the use of defibrillators is often a race against time. Therefore, if there is a way to quickly and evenly apply the defibrillator cream, it will effectively improve the defibrillation effect and the timeliness of defibrillation. Summary of the invention

[0023] Combination Figure 1-5 The defibrillation auxiliary device shown is used to apply defibrillation paste to the electrodes of the defibrillator, which solves the problems of inconvenient operation and uneven coating of traditional manual coating. Figure 1 As shown in the figure, it includes a storage box 1, a supporting mechanism and a coating mechanism. The storage box 1 is used to store the defibrillation cream, the coating mechanism is used to apply the defibrillation cream on the electrode, and the supporting mechanism is used to support the coating mechanism. The present invention adopts a rotary coating method, that is, the electrode is contacted with the coating surface of the coating mechanism (that is, the disk surface described below), and the defibrillation cream is evenly coated on the electrode through the rotation of the coating mechanism.

[0024] The storage box 1 is connected to the coating mechanism through a supporting mechanism, which not only plays a supporting role, but also has the function of transporting the defibrillator cream to the coating mechanism. Figure 1 As shown in the figure, the supporting mechanism of the present invention includes a vertical pole 2 arranged on the top of the storage box 1, the vertical pole 2 is a hollow pole, a connecting box 3 is arranged at the upper end of the vertical pole 2, and a conveying pump 4 is arranged in the middle section of the vertical pole 2. The conveying pump 4 is connected to the connecting box 3 through a connecting pipe 5 arranged inside the vertical pole 2. The conveying pump 4 can be a screw pump, but it is best to use a peristaltic pump, which has accurate conveying and a certain metering effect, and is particularly suitable for small-scale conveying needs such as the present invention.

[0025] The coating mechanism of the present invention comprises a coating disc and a driving assembly for driving the coating disc to rotate, Figure 1 and 2 As shown in , the coating disc includes a tubular disc neck 6 and a disc body 7 arranged at one end of the disc neck 6. The end of the disc neck 6 away from the disc body 7 extends into the connection box 3 and forms a rotational fit with the connection box 3.

[0026] The plate body 7 is provided with a flat plate cavity 8, which is a flat circular cavity, and its thickness is usually about 3-7 mm, and the plate cavity 8 is connected with the inner cavity of the plate neck 6. The plate surface of the plate body 7 is provided with a plurality of discharge holes 9 connected with the plate cavity 8.

[0027] When the defibrillator cream needs to be applied, the device of the present invention is turned on, and the delivery pump 4 pumps the defibrillator cream stored in the storage box 1 to the surface of the coating disk through the connecting tube 5, the connecting box 3, the disk neck 6, the disk cavity 8, and the discharge hole 9 in sequence. The user brings the electrode into contact with the surface of the coating disk, and with the rapid rotation of the coating disk, the defibrillator cream is evenly coated on the entire electrode surface under the action of friction. Compared with the traditional method of manually applying the defibrillator cream, the present invention can effectively ensure the uniformity of the defibrillator cream application, and the application is more convenient. Of course, in order to further improve the dispersion effect, such as Figure 2 As shown in the figure, the present invention can also cover the surface of the disk body 7 with a layer of mesh cloth 10. The material is dispersed coarsely through the discharge hole 9 and finely dispersed through the mesh cloth 10. The mesh cloth 10 also has a certain flexibility, which can prevent the electrode from being worn after long-term use.

[0028] In addition, in order to make the defibrillation cream delivered to the disc cavity 8 be more stably dispersed to each discharge hole 9, the Figure 4 and 1 As shown in the figure, a plurality of guide edges 11 extending radially along the disc body 7 are arranged on the inner side wall of the disc cavity 8 close to the disc neck 6. The guide edges 11 can guide the defibrillator paste so that it is more evenly dispersed in the entire circular disc cavity 8.

[0029] The present invention can be provided with one coating disk, and one electrode is coated before the other electrode is coated during use, but a better approach is that two coating disks are provided, and the two coating disks are symmetrically distributed on both sides of the connection box 3. It can meet the requirements of simultaneous coating of two electrodes.

[0030] Regarding the driving form of the coating disc, there are many specific structures. As shown in the figure, the driving assembly of the present invention may include a passive wheel 12, a driving wheel 13, a driving shaft 14 and a driving motor 15. The passive wheel 12 is arranged on the disc neck 6. The driving motor 15 is arranged on the top of the storage box 1, and the driving motor 15 is connected to the driving shaft 14. The driving wheel 13 is arranged on the driving shaft 14, and the driving wheel 13 and the passive wheel 12 are matched by a transmission belt 16.

[0031] In the case where two coating discs are provided, the disc necks 6 of the two coating discs can be connected in the connection box 3 through the short pipe 17, which can effectively increase the rotation stability of the two coating discs. Of course, in order to facilitate the defibrillation paste to enter the disc neck 6, a plurality of feeding holes 18 are evenly arranged on the side wall of the short pipe 17. In addition, in the case where the short pipe 17 is provided, the feeding hole 18 can be designed as follows: Figure 5The inclined hole shown in the figure, and the inner end section of the material hole 18 is smaller than the outer end section. In this way, the short pipe 17 can also play a pump push role during the rotation process to reduce the load of the peristaltic pump, and only a small pump body is used, which is of great significance to the realization of miniaturization.

[0032] In addition, since the present invention coats the defibrillator cream by rotating the coating disc, when the delivery pump is unstable during the rotation process, too much defibrillator cream may be delivered to the coating disc. During the rapid rotation, it may be affected by the centrifugal force and may slip out from the side edge. Therefore, the present invention can also be as follows: Figure 2 As shown in FIG. 1 , a circle of annular edge grooves 19 are arranged on the circumferential side of the disk surface of the disk body 7 .

[0033] Regarding the start-up form of the present invention, it can adopt the form of pressure feedback, that is, when the electrode and the coating disk are in contact, the two have pressure signal feedback, so that the device starts, and this method can simplify the process of switching the device. Of course, in order to achieve this function, the present invention can also include a pressure sensor for collecting the contact signal between the electrode and the coating disk, and its installation position is not limited, as long as the contact feedback signal of the two can be collected, the pressure sensor is electrically connected to the controller 20, and the controller 20 is installed on one side of the storage box 1.
