A portable tidal capnography recording device

Abstract

A portable tidal capnogram recording device of the present invention relates to the field of medical equipment and physiological signal monitoring, comprising a circuit board equipped with a microprocessor, a power management module electrically connected to the circuit board, and a carbon dioxide monitoring module connected to the circuit board , the carbon dioxide monitoring module includes a breathing mouthpiece, an airway connected to the airway of the breathing mouthpiece, a monitoring unit connected to one end of the airway, and an air suction pump connected to the monitoring unit through a rubber hose. The air suction pump communicates with the power management module through a microcontroller It is electrically connected, and by adjusting the suction flow of the air pump, the carbon dioxide detector can be easily applied to different groups of people for monitoring; by setting the temperature detection monitoring module and the heating module, it can effectively prevent water vapor condensation and further improve the accuracy of concentration detection sex.

Description

technical field [0001] The invention relates to the field of medical equipment and physiological signal monitoring, in particular to a portable tidal capnogram recording device. Background technique [0002] Currently, respiratory diseases are highly prevalent, such as chronic obstructive pulmonary disease (COPD) and asthma, which are common lung diseases. Acute exacerbation of the disease is the most important cause of lung damage and death in patients. In order to reduce the injury and death events caused by acute exacerbation, effective early warning of acute exacerbation is needed, so that timely treatment can be given before the event occurs. In order to achieve effective early warning of acute exacerbation events, patients need to be monitored daily, and the upcoming exacerbation events can be identified by monitoring the changing trends of relevant physiological indicators. Studies have shown that daily tidal carbon dioxide monitoring for patients can achieve effect...
