Detection device for battery of anesthesia machine

Abstract

The invention provides an anaesthesia machine accumulator detection apparatus, comprising a voltage sampling module used for sampling a feedback signal outputted by the voltage of an accumulator; a signal processing module connected with the voltage sampling module, and used for obtaining the feedback signal outputted by the voltage, and amplifying the feedback signal outputted by the voltage; and an alarm module used for adjusting a preset reference voltage feedback signal, and obtaining the amplified feedback signal to compare with the preset reference voltage feedback signal so as to allow the alarm module to give an alarm when the voltage feedback signal is lower than the preset voltage references feedback signal. The apparatus employs a pure simulation circuit design to avoid the problems such as dead halt; in addition, a user can flexibly set load current, and meanwhile can set an accumulator qualified scope so as to determine accumulator characteristics before starting up, and give an alarm in the case of low accumulator voltage, thereby avoiding dangerous situations possibly caused by accumulator aging or passivation.

Description

technical field [0001] The invention relates to the field of medical equipment manufacturing, in particular to a detection device for an anesthesia machine battery. Background technique [0002] The anesthesia machine used in the intensive care unit may not be used frequently in practical applications, so it is easy to cause the internal backup battery to passivate or age due to long-term non-use, causing its performance to decline to varying degrees, or even scrapped. When this situation occurs, it often shows that the battery is full when the machine is turned on, but it shuts down after a short period of time. It is likely that the device cannot be used due to the lack of time to replace the battery or other reasons, causing serious consequences. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] For this reason, the first object of the present invention is to propose a detection devic...
