Carbon dioxide measuring instrument

Abstract

The invention discloses a carbon dioxide measuring instrument. The carbon dioxide measuring instrument comprises a shell which defines a sealed carbon dioxide detection space, an air carbon dioxide sensor which is arranged in the carbon dioxide detection space and used for detecting the concentration of carbon dioxide in the carbon dioxide detection space, a data processor which is connected to the air carbon dioxide sensor and used for analyzing and processing the concentration of carbon dioxide to obtain partial pressure of carbon dioxide in the blood, a display screen which is embedded in the shell and connected to the data processor, an elasticity wrist strap which is connected to the shell, a constant temperature heating member which is arranged on the inner side of the shell, and a sealing ring which sleeves the shell. The carbon dioxide measuring instrument has the advantages of being small in size, being wearable in use, being low in price, being non-invasive in detection, andthe like.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a carbon dioxide measuring instrument. Background technique [0002] At present, cardiopulmonary disease is the main killer of human health. Take chronic obstructive pulmonary disease (COPD) as an example. The third place, becoming the fifth place in the world's economic burden of disease. In recent years, with the development of economy and society, the increasing smog has increased the incidence of cardiopulmonary diseases. Under the concept of "Healthy China" in the new era, higher requirements are put forward for the diagnosis and treatment of cardiopulmonary diseases. The partial pressure of carbon dioxide in arterial blood is an important reference index for clinical diagnosis of cardiopulmonary diseases. The current detection of partial pressure of carbon dioxide in arterial blood mainly relies on invasive arterial blood gas analysis, which is limited by the external envi...

Problems solved by technology

The partial pressure of carbon dioxide in arterial blood is an important reference index for clinical diagnosis of cardiopulmonary diseases. The current detection of partial pressure of carbon dioxide in arterial blood mainly relies on invasive arterial blood gas analysis, which is limited by the external environment such as temperature, humidity and air pressure, and is Invasive examination requires high levels of arterial puncture for medical staff and peripheral arterial pulsation of patients. The blood gas analysis equipment currently used in clinical practice is bulky, expensive, and extremely poor in portability. It cannot realize real-time dynamic detection of partial pressure of carbon dioxide. It can be seen that the improvement of the carbon dioxide partial pressure detection equipment is imminent
