Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a bite structure with oxygen supply monitoring. Background Art

[0002] Gastroscopy refers to the use of instruments through the mouth to enter the esophagus, stomach, duodenal bulb and upper part of the stomach for diagnosing and treating.

[0003] At present, in order to achieve safe operation of painless (under anesthesia) gastroscopy, the patient must be mechanically oxygenated while undergoing gastroscopy, and the patient's breathing must be monitored by a carbon dioxide end-tidal monitor to prevent suffocation. Therefore, the bite mouth used for gastroscopy includes a gastroscopy channel for the passage of the gastroscope, an oxygen supply channel for mechanically supplying oxygen to the patient, and a carbon dioxide end-tidal monitoring channel for monitoring the patient's breathing. The oxygen supply channel and the carbon dioxide end-tidal monitoring channel are independently set and not connected to each other. Both the oxygen supply channel and the carbon dioxide end-tidal monitoring channel are T-shaped tube structures. One of the three ports of each T-shaped tube is connected to the human nasal cavity, and the other port corresponds to the human oral cavity. Each of the oral cavity and nasal cavity supplies oxygen to the patient and collects carbon dioxide. However, in this bite structure, on the one hand, since the oxygen supply channel and the carbon dioxide end-tidal monitoring channel are both external T-tube structures, the overall structure of the bite is relatively complex, inconvenient to manufacture, and has poor aesthetics; on the other hand, the ports of the oxygen supply channel and the carbon dioxide end-tidal monitoring channel connecting to the oral cavity are arranged on the side wall of the gastroscope channel, rather than facing the patient's mouth. When performing a gastroscopy and the gastroscope passes through the gastroscope channel, the position of the gastroscope needs to be positioned to ensure that there is a gap between the gastroscope and the port to ensure that oral oxygen supply and oral carbon dioxide collection operations can be performed. This structure brings inconvenience to the insertion and positioning of the gastroscope, and is not convenient for collecting carbon dioxide exhaled from the mouth. Utility Model Content

[0004] In view of this, the present invention aims to propose a bite structure with oxygen supply monitoring, so as to realize the precise monitoring of the patient's end-tidal carbon dioxide while inserting a gastroscopic catheter and supplying oxygen.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A bite structure with oxygen supply monitoring includes a bite and a baffle arranged at the outer end thereof, the bite having a gastroscope channel and an oral monitoring channel arranged side by side, the upper portion of the baffle being integrally formed with a nose bridge portion that faces the human nostrils, the nose bridge portion being provided with an oxygen supply nasal catheter and a monitoring nasal catheter, an oxygen supply channel and a carbon dioxide monitoring channel that are not connected to each other being provided inside the baffle, the oxygen supply channel being externally connected to an oxygen supply tube, the carbon dioxide monitoring channel being externally connected to a monitoring connecting tube, the oxygen supply nasal catheter being connected to the oxygen supply channel, and the monitoring nasal catheter and the oral monitoring channel being both connected to the carbon dioxide monitoring channel.

[0007] Furthermore, the oxygen supply pipe and the monitoring connecting pipe are both hose structures and are gathered in the adjustment ring, and the oxygen supply pipe and the monitoring connecting pipe can slide relative to the adjustment ring.

[0008] Furthermore, a Luer connector is provided at the distal end of the monitoring connecting tube.

[0009] Furthermore, the oxygen supply nasal catheter and the monitoring nasal catheter are respectively arc-shaped tube structures with the insertion ports tilted upward.

[0010] Furthermore, the baffle is provided with ventilation holes around the bite.

[0011] Furthermore, the top surface of the nose bridge is an arc-shaped surface.

[0012] Compared with the prior art, the bite structure with oxygen supply monitoring described in the present invention has the following advantages:

[0013] (1) The utility model has a compact structure, is simple and beautiful, and can supply oxygen to the patient while performing gastroscopy and monitor the patient's end-tidal carbon dioxide. The end-tidal carbon dioxide monitoring is to output and monitor the intersection of the carbon dioxide exhaled from the patient's oral cavity and nasal cavity, thereby improving the accuracy of the patient's end-tidal carbon dioxide monitoring.

[0014] (2) In the present invention, the oral monitoring channel and the gastroscope channel are arranged side by side and face the human oral cavity, so that the insertion of the gastroscope and the collection of oral carbon dioxide do not affect each other, which facilitates the insertion of the gastroscope and does not require positioning of the gastroscope.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figure 1 、 Figure 2 As shown, a mouthpiece structure with oxygen supply monitoring includes a mouthpiece 2 and a baffle 1 provided at the outer end of the mouthpiece 2. The baffle 1 prevents the entire mouthpiece from entering the oral cavity. The mouthpiece 2 has a gastroscope channel 21 and an oral monitoring channel 22 arranged side by side. The upper part of the baffle 1 is integrally formed with a nose bridge portion 11 that is directly opposite to the human nostrils. For comfortable wearing, the top surface of the nose bridge portion 11 is an arc-shaped surface. The nose bridge portion 11 is provided with an oxygen supply nasal catheter 4 and a monitoring nasal catheter 3 corresponding to the human nostrils to achieve single nasal cavity oxygen supply and single nasal cavity carbon dioxide collection. An oxygen supply channel and a carbon dioxide monitoring channel that are not connected to each other are provided in the baffle 1. The oxygen supply nasal catheter 4 is connected to the oxygen supply channel, and the monitoring nasal catheter 3 and the oral monitoring channel 22 are both connected to the carbon dioxide monitoring channel. The oxygen supply channel passes through the side of the baffle 1 and is externally connected to the oxygen supply pipe 6, which is used to connect to the oxygen supply machine. The carbon dioxide monitoring channel passes through the side of the baffle 1 and is externally connected to the monitoring connecting pipe 5. The distal interface of the monitoring connecting pipe 5 is provided with a Luer connector 8 for connection to the carbon dioxide end-tidal monitoring equipment.

[0022] The present invention enables the patient to be supplied with oxygen and to monitor end-tidal CO2 while undergoing gastroscopy. During end-tidal CO2 monitoring, the CO2 exhaled from the patient's oral cavity and nasal cavity is combined and output to the monitoring device, thereby improving the accuracy of CO2 monitoring. Since the gastroscopy channel 21 and the oral monitoring channel 22 of the mouthpiece 2 are arranged side by side and face the human oral cavity, they do not interfere with or affect each other, facilitating the passage of the gastroscope. The gas exhaled by the patient can also directly enter the oral monitoring channel 22, and then merge with the CO2 from the nasal cavity into the CO2 monitoring channel, and finally be transported to the end-tidal CO2 monitoring device through the monitoring connecting tube 5 for monitoring, thereby improving the accuracy of CO2 monitoring.

[0023] In the present invention, both the oxygen supply tube 6 and the monitoring connection tube 5 are flexible tubes and are confined to an adjustment ring 7. These tubes can slide relative to the adjustment ring 7. This structure allows the position of the adjustment ring 7 to be adjusted according to the patient's wearing needs. Because the adjustment ring 7 constrains the oxygen supply tube 6 and the monitoring connection tube 5, it ensures a stable fit for patients undergoing gastroscopy.

[0024] In the present invention, the oxygen supply nasal catheter 4 and the monitoring nasal catheter 3 are respectively arc-shaped tube structures with the insertion ports tilted upward, so that the bite structure of the present invention corresponds to the physiological structure of the human body, improves wearing comfort, and ensures smooth insertion of the gastroscope, smooth oxygen supply and smooth collection of carbon dioxide.

[0025] In the present invention, the baffle 1 is provided with ventilation holes 9 around the bite opening 2 to improve wearing comfort.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
