Abstract

The invention provides a sound alarm device, a monitoring method of the sound alarm device, and an anesthesia machine. The sound alarm device includes a power amplifier circuit and a speaker connected to the power amplifier circuit, and also includes: a resistor, the first end of which is connected to the power amplifier circuit. The ground pin of the power amplifier circuit is connected, and the second end is a measurement end. The invention is used to solve the problem in the prior art that the horn cannot reflect that the machine has broken down when the machine breaks down or the horn is damaged. By adopting the technical scheme of the invention, a detection circuit is connected to the horn, and the signal is amplified. The current working state of the horn can be reflected in real time by detecting the obtained electrical signal. The fault of the horn and the fault of the circuit can be found in time, which reduces the risk and improves the safety performance.

Description

technical field [0001] The invention relates to a sound alarm device, a monitoring method of the sound alarm device and an anesthesia machine. Background technique [0002] The anesthesia machine is an auxiliary device that guides the patient to inhale anesthetic gas and perform mechanical ventilation during the operation. It is a medical device that is often used in the operation. The horn on the anesthesia machine can emit sound to detect the state of the anesthesia machine. When the anesthesia machine breaks down, the horn will sound an alarm. Prompt the anesthetist to pay attention by sound, and at the same time, there is an alarm prompt message on the display device. However, if the alarm circuit breaks down and is not detected, other alarms may not be discovered in time, so that the reliability of the anesthesia machine failure alarm is insufficient. [0003] In the prior art, there is a problem of insufficient reliability of the failure alarm of the anesthesia machi...
