However, if there is a fault during the charging process, the charging current will be too large, the charging circuit will be damaged, and in severe cases, the circuit will burn out. Therefore, it is necessary to limit and control the charging current of the circuit in the charging circuit.
[0003] At present, the usual overcurrent protection is to protect the defibrillation charging circuit in a single way, such as installing a fuse. When an overcurrent occurs and the fuse fails, the charging current of the defibrillation equipment is too large, which is likely to cause onboard The risk of fire caused by the large area of the device burned
Therefore, the safety and stability of the existing defibrillation charging overcurrent protection device are not high

The invention discloses a defibrillation charging overcurrent protection device for a defibrillation monitor and the defibrillation monitor. The defibrillation charging overcurrent protection device for the defibrillation monitor includes a first protection module, a second protection module and a processing module. The first protection module and the second protection module are connected in series in the charging circuit of the defibrillation monitor, and the first protection module and the second protection module are respectively connected to the processing module, and the first protection module is used to send voltage data or current data to the processing module , the processing module is provided with a first reference value, and when the voltage data or current data is greater than the first reference value, a power-off signal is sent; the second protection module is provided with a second reference value, when the current in the charging circuit is greater than the second reference value When the corresponding current value is reached, the second protection module disconnects the charging circuit. Through the two-level overcurrent protection, the safety and stability of the charging circuit are higher, which greatly improves the safety and reliability of the equipment.
Description
technical field [0001] The invention relates to the technical field of overcurrent protection, in particular to a defibrillation charging overcurrent protection device for a defibrillation monitor and the defibrillation monitor. Background technique [0002] The defibrillation monitor is a medical device used to monitor the patient's vital signs, external defibrillation, internal defibrillation and pacing, and its safety level is higher than that of the general monitor. When charging the defibrillator monitor, the shorter the charging time, the better, so as to shorten the rescue time of the patient, so the maximum charging current of the defibrillator monitor can reach more than 10A. However, if a fault occurs during the charging process and the charging current is too large, the charging circuit will be damaged, and in severe cases, the circuit will burn out. Therefore, it is necessary to limit and control the charging current of the circuit in the charging circuit. [00...
