AI Technical Summary

Technical Problem

There may be dead cavity inside the joint of the existing tracheal intubation, resulting in carbon dioxide retention, affecting the real-time accuracy of monitoring. When the patient's exhaled warm gas enters the joint, water vapor condensation may affect the air circulation, resulting in delayed monitoring results.

Method used

A tracheal intubation tube is designed, and the joint is equipped with a guide assembly and a one-way circulation assembly. A stable circulation passage is formed through the partition plate, side plate and one-way circulation assembly to avoid the formation of dead cavity, and the condensate water is treated through the drainage assembly to ensure that the gas circulation is not affected.

Benefits of technology

The full circulation of gas inside the joint is achieved, carbon dioxide retention is avoided, the real-time and accuracy of the monitoring results are ensured, and the condensation of water vapor is prevented from affecting the gas circulation through the drainage assembly, improving the accuracy and stability of monitoring.

Abstract

The invention relates to the technical field of medical instruments, and discloses a trachea cannula capable of performing end-tidal carbon dioxide detection, which comprises a hose, an air bag arranged on the outer side of the hose, a flexible trachea arranged on the outer side of the air bag, a joint arranged on the outer side of the hose, a joint arranged on the outer side of the joint, an oxygen connecting pipe and a guide assembly arranged in the joint, the guide assembly specifically comprises a partition plate arranged in the connector. According to the trachea cannula capable of carrying out end-expiratory carbon dioxide detection, by arranging the guide assembly, when the trachea cannula works, oxygen enters the first interval through the oxygen connecting pipe and then enters the second interval and the hose in sequence, and exhaled gas enters the third interval from the hose and then enters the fourth interval, the first interval and the oxygen connecting pipe in sequence; in this way, the space in the main body is divided to form a stable circulation channel, gas in the main body circulates sufficiently, dead cavities are avoided, and the accuracy of monitoring results is guaranteed.
