Embodiment 1

[0024] Such as Figure 1-8 As shown, the defibrillator provided by Embodiment 1 of the present invention includes a front shell 100, a rear shell 200, a defibrillation capacitor 300, and a release resistor 400. The front shell 100 is connected to the rear shell 200 to form an inner cavity 1200. Both the defibrillation capacitor 300 and the release resistor 400 are arranged in the inner cavity 1200 , and the defibrillation capacitor 300 is arranged close to the bottom of the inner cavity 1200 , and the release resistor 400 is arranged near the top of the inner cavity 1200 . The release resistor 400 is mainly used to discharge energy. During work, since a large amount of energy will be directly discharged on the release resistor 400, it will cause a sharp temperature rise of the release resistor 400. Therefore, the release resistor 400 is a One of the most important heating components in the trillometer. In the embodiment of the present invention, the release resistor 400 is ar...

Embodiment 2

[0059] refer to figure 2 , image 3 and Figure 9 As shown, the difference between the defibrillator provided in this embodiment and the first embodiment is that this embodiment also includes an optional module 1100 on the basis of the first embodiment, and the setting of the DC-AC converter 500 in this embodiment The location is different from that of the DC / AC converter 500 in the first embodiment.

[0060]Specifically, in this embodiment, the matching module 1100 is a carbon dioxide detection module for detecting carbon dioxide, the DC-AC converter 500 is set in the second storage tank 236, and the matching module 1100 is set in the third storage tank. Inside the groove 237. The carbon dioxide detection module is a heat-sensitive component, and placing the carbon dioxide detection module in the third storage tank 237 can help reduce the influence of the carbon dioxide detection module from rising hot air in the inner cavity 1200 . Of course, the optional module 1100 is...

Embodiment 3

[0064] The difference between the defibrillator provided in this embodiment and Embodiment 1 and Embodiment 2 mainly lies in the arrangement of the DC-AC converter 500 . Specifically, in Embodiment 1 and Embodiment 2, the DC-AC converter 500 is arranged in the inner cavity 1200; while in this embodiment, the DC-AC converter 500 is arranged outside the inner cavity 1200, that is, the battery 700 is not installed in the rear shell 200 , the front shell 100 or the rear shell 200 is provided with a first socket (not shown) for plugging the connector of the DC-AC converter 500 , and the first socket is electrically connected to the circuit board assembly 600 . In some embodiments, the connector includes a connecting wire. In a specific application, the DC-AC converter 500 is plugged into the first plug interface through the connector, so as to realize the electrical connection between the DC-AC converter 500 and the circuit board assembly 600 . In this embodiment, the DC-AC conver...

Abstract

The invention is applicable to the field of medical equipment, and discloses a defibrillator which comprises a front shell, a rear shell, a defibrillation capacitor and a release resistor, the front shell and the rear shell are connected and define an inner cavity, the defibrillation capacitor and the release resistor are both arranged in the inner cavity, the defibrillation capacitor is arranged close to the bottom of the inner cavity, and the release resistor is arranged close to the top of the inner cavity. According to the defibrillator, the release resistor serving as one of main heating components of the defibrillator is arranged at the position close to the top of the inner cavity, so that additional temperature rise of other components caused by rising of hot air generated when the release resistor works can be avoided. Meanwhile, the defibrillation capacitor serving as one of main heat-sensitive parts of the defibrillator is arranged at the position close to the bottom of the inner cavity, so that the phenomenon of temperature rise of the defibrillator capacitor caused by rising of hot air in the defibrillator can be avoided, the working temperature requirement of the defibrillator can be met on the premise that a cooling fan is not arranged, and the service life of the defibrillator is prolonged. And the heat dissipation problem in the miniaturization design of the defibrillator is solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a defibrillator. Background technique [0002] The defibrillator is mainly used for defibrillation treatment of dangerous diseases such as ventricular fibrillation and atrial fibrillation, and is generally used in the hospital emergency department or pre-hospital first aid. The defibrillator can work in monitoring mode, pacing mode, manual defibrillation mode and automatic defibrillation (AED) mode according to actual clinical scenarios. Among them, the monitoring mode is mainly used to monitor the vital sign parameters of the patient, so as to judge the patient's condition or monitor the patient after rescue for a long time. The pacing mode is mainly used to treat patients with bradycardia and improve the patient's cardiac cycle. The manual defibrillation mode is mainly used for defibrillation treatment for patients with fatal arrhythmia such as ventricular tachycardia, ventri...
