Oxygen inhalation device for single-cavity nasal catheter apable of monitoring CO2 concentration

Abstract

The invention discloses an oxygen inhalation device for a single-cavity nasal catheter capable of monitoring CO2 concentration. The oxygen inhalation device comprises a catheter joint, wherein a rubber spacer ring is arranged in the middle of an inner cavity of the catheter joint, an oxygen output catheter and a CO2 sampling tube are arranged on the surface of the catheter joint on two sides of the rubber spacer ring respectively, a rubber nasal plug is detachably arranged on the CO2 sampling tube in a sleeving manner, the rubber nasal plug can be stuffed into a nostril, so that the CO2 sampling tube is located in the nostril and cannot fall off, the accuracy of the CO2 concentration detection is improved, the rubber nasal plug is an arc-shaped soft plug in a circular truncated cone shape,and a first input tube and a first output tube are arranged at two ends of the catheter joint. Compared with the prior art, the oxygen inhalation device can collected CO2 exhaled by a patient for following detection; and attraction magnets can attract the surface of a medical sickbed, so that a second input tube or a second output tube is attached to the bedside, and the condition that the patient kicks the tubes during turning or movement to cause instrument disconnection is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device capable of monitoring end-tidal CO 2 Oxygen inhalation device with single lumen nasal cannula. Background technique [0002] Oxygen inhalation is the inhalation of oxygen, which is a commonly used clinical treatment method. It is used to correct hypoxia, increase arterial oxygen partial pressure and oxygen saturation level, etc. It is one of the important methods in auxiliary treatment of various diseases and painless diagnosis and treatment; Due to the increasing demand for comfortable medical care, the number of patients undergoing painless diagnosis and treatment such as painless gastrointestinal endoscopy, painless abortion, and painless bronchoscopy is gradually increasing. During general anesthesia for painless diagnosis and treatment, endotracheal intubation is not required, and the patient can still keep breathing spontaneously. Usually patients use oxy...

AI Technical Summary

Problems solved by technology

Usually patients use oxygen inhalation nasal cannula during oxygen inhalation to ensure that they have sufficient oxygen supply; however, traditional nasal cannula can only be used for oxygen supply and cannot monitor end-tidal CO 2 Concentration, so the respiratory condition of the patient cannot be perfectly monitored

In addition, the traditional nasal cannula is easy to fall off during use, and the nasal cannula needs to be continuously inserted into the patient's nasal cavity, which will cause errors in monitoring. Therefore, we provide a device that can monitor end-tidal CO 2 The oxygen inhalation device of the single-chamber nasal catheter of concentration, to solve the problem proposed in the above-mentioned background technology
