Description

Anesthesia nasal oxygen inhalation tube for monitoring

technical field

The utility model relates to an apparatus for medical anesthesia, in particular to a nasal oxygen inhalation tube for anesthesia which can monitor the carbon dioxide concentration.

Background technique

In the prior art, local anesthesia monitoring and non-general anesthesia monitoring are commonly used anesthesia methods in daily operations. In order to ensure the safety of patients, patients need to inhale oxygen during the operation. Compared with other oxygen inhalation tools such as masks, oxygen inhalation tubes are easier Accepted by patients, especially conscious patients. Intraoperative monitoring is mainly to monitor the patient's vital signs, such as ECG monitoring, pulse oximetry and blood pressure monitoring, etc. However, such monitoring lacks objective monitoring of the patient's respiratory status. In many cases, the operation needs to cover the patient's face and chest, making it difficult for the anesthesiologist to observe the patient's breathing state. If the patient suffers from respiratory depression, the anesthesiologist cannot detect it in time. By the time the vital signs appear abnormal, the patient's respiratory depression is already serious, which makes the anesthesiologist's rescue hasty and difficult.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a nasal oxygen suction tube for anesthesia department that can monitor the end-tidal carbon dioxide concentration. The oxygen suction tube is easy to operate and easy to be accepted by patients. Patients under monitoring and non-general anesthesia monitoring, especially those whose respiratory status cannot be observed due to surgical reasons, can monitor their end-tidal carbon dioxide concentration while ensuring sufficient oxygen supply, which improves the safety of anesthesia monitoring and provides Anesthesiologists provide a safe and easy method of respiratory monitoring.

The purpose of this utility model is achieved by the following technical solutions:

An anesthesia nasal oxygen inhalation tube for monitoring, which is sequentially connected with a gas source connector, a catheter, a bifurcated connector, a fixed ring, a double-hole nose tip and a nose tip catheter, and a gas sampling tube is arranged in one side of the double-hole nose tip. The front end of the gas sampling tube is 0.8-1.2 mm beyond the mouth of the nose tip, and the end of the gas sampling tube is provided with an external connector for connecting to a carbon dioxide monitoring system.

The inner diameter of the gas sampling pipe is 1.1-1.5 mm.

The gas sampling tube is made of silica gel.

The air sampling tube and the nose sub-duct are in an isolated state.

The external joint is trumpet-shaped.

Compared with the prior art, the beneficial effects brought by the technical solution of the utility model are:

Because the nose hole of the utility model is also provided with a gas sampling tube, the gas sampling tube is kept isolated from the nose tube, and the end is also provided with an external joint, which can monitor the concentration of carbon dioxide at the end of the breath while ensuring sufficient oxygen supply. The safety of anesthesia monitoring is improved. At the same time, the gas sampling tube is made of silicone, which will not damage the nasal mucosa during use, and is easy to be accepted by patients, safe and reliable.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 2, a monitoring anesthesia nasal oxygen inhalation tube includes a gas source connector 1, a catheter 2, a bifurcated connector 3, a fixed ring 4, a double-hole nose tip 5 and a nose tip tube 8. A gas collection tube 6 is arranged in one of the channels of the hole nose head 5, and the front end of the gas collection tube 6 exceeds the mouth of the nose head by 0.8-1.2 mm to reduce the dilution of the exhaled gas by oxygen, but the excess part should not be too long. The end of the gas sampling pipe 6 is provided with an external joint 7, which adopts a trumpet-shaped interface and can be connected with a standard exhaust gas sampling conduit, which is finally connected to a carbon dioxide detection system. The gas collection tube 6 is made of silica gel with an inner diameter of 1.1-1.5mm to avoid damaging the nasal mucosa. The catheter 2 and the nose tube 8 are made of plastic hose. The circulation is isolated from each other and does not interfere with each other. When in use, connect the gas source connector 1 to the oxygen flow bottle to supply oxygen to the patient; the outer connector 7 of the gas sampling tube 6 is connected to the exhaust gas sampling tube and the end-tidal carbon dioxide monitoring system Connect to monitor end-tidal carbon dioxide concentration. For patients under local anesthesia monitoring and non-general anesthesia monitoring, especially for patients whose respiratory conditions cannot be observed due to surgical reasons, while ensuring sufficient oxygen supply, the end-tidal carbon dioxide concentration can be monitored, providing anesthesiologists with Oxygen tube oxygen inhalation is a convenient method for directly monitoring the respiratory status of patients under local anesthesia, which improves the safety of anesthesia monitoring.
