Converter for monitoring end-breath carbon dioxide and using method thereof

Abstract

The invention provides a converter for monitoring end-tidal carbon dioxide, which comprises a converter body and is characterized in that a space for circulating gas is reserved in the converter; the outer wall of the converter body is provided with a first interface and a second interface, and the first interface and the second interface are communicated through a first channel. The outer wall of the converter body is also provided with a third interface and a fourth interface which are communicated with the space. The third connector is used for being connected with a nasal oxygen inhalation tube. The fourth connector is used for being connected with the large-diameter end of the mainstream type end-tidal carbon dioxide monitor sampler; the converter body is provided with the first connector, the second connector and the third connector, sampling of gas exhaled by a patient when an oxygen mask and a snorting type oxygen catheter are used is achieved, meanwhile, the fourth connector can be used for being connected with the large-diameter end of a mainstream type end-tidal carbon dioxide monitor sampler, and therefore the sampling efficiency is improved. The detection on the exhaled gas of the patient is realized.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a converter for monitoring end-tidal carbon dioxide and a method for using the same. Background technique [0002] End-tidal carbon dioxide monitoring is a non-invasive, simple, real-time, continuous functional monitoring index; carbon dioxide waveform is a non-invasive detection method for evaluating systemic metabolism, cardiac output, and pulmonary perfusion in various clinical situations In addition, the carbon dioxide waveform is superior to the pulse oximeter in quickly identifying apnea and airway lesions, because compared with the instantaneous change in end-tidal carbon dioxide monitoring, the change of blood oxygen saturation has a certain delay; For patients who retain spontaneous breathing without endotracheal intubation, the application of end-tidal carbon dioxide monitoring combined with blood oxygen saturation monitoring can accurately and tim...

[0002] End-tidal carbon dioxide monitoring is a non-invasive, simple, real-time, continuous functional monitoring index; carbon dioxide waveform is a non-invasive detection method for evaluating systemic metabolism, cardiac output, and pulmonary perfusion in various clinical situations In addition, the carbon dioxide waveform is superior to the pulse oximeter in quickly identifying apnea and airway lesions, because compared with the instantaneous change in end-tidal carbon dioxide monitoring, the change of blood oxygen saturation has a certain delay; For patients who retain spontaneous breathing without endotracheal intubation, the application of end-tidal carbon dioxide monitoring combined with blood oxygen saturation monitoring can accurately and timely understand the patient's respiratory status and effectively improve the safety of patients under intravenous general anesthesia; Endotracheal intubation retains spontaneous breathing and does not use a breathing circuit for patients who inhale ordinary oxygen. The end-tidal carbon dioxide monitor cannot match the ordinary oxygen inhalation pipeline for end-tidal carbon dioxide monitoring; in the medical field, end-tidal carbon dioxide monitoring has been defaulted by most people It is the sixth vital sign. Therefore, in the actual examination and clinical treatment of patients, the demand for matching the end-tidal carbon dioxide monitor with the ordinary oxygen inhalation pipeline for detection is increasing

[0003] The inventor found that the design of the existing end-tidal carbon dioxide monitor is mainly matched with the breathing circuit, therefore, it can only monitor the end-tidal carbon dioxide for the mechanically ventilated patients who use the breathing circuit; the patients who do not use the breathing circuit, such as oxygen masks and In the case of nasal inhalation oxygen tube, the existing end-tidal carbon dioxide monitor cannot be used to monitor end-tidal carbon dioxide; and there are also differences in the interfaces between different types of end-tidal carbon dioxide monitors and different types of breathing circuits, resulting in inflexible and timely monitoring. monitoring problem
