Abstract
The utility model relates to the technical field of medical instruments, particularly to an oxygen therapy and breathed air collection integrated end expiration CO2 monitoring conduit used for an end expiration CO2 monitoring device, which is especially applicable to the anesthesia of non-trachea cannula patients. The conduit comprises an oxygen therapy conduit (1), a breathed air collection conduit (2), a conduit connection pipe (3), a conduit length regulating sleeve (4), an oxygen cylinder connector (5) and a monitoring device connector (6), wherein a septum is arranged in the middle of the conduit connection pipe (3), two naris cannulas (8) are respectively arranged on the left and the right sides of the septum, and two ends of the conduit connection pipe (3) are respectively connected with one end of the oxygen therapy conduit and one end of the breathed air collection conduit. As the septum is arranged in the middle of the conduit connection pipe, oxygen in the oxygen therapy conduit affects neither the constituent nor the concentration of the air in the breathed air collection conduit, so that the detection result of the end expiration CO2 monitoring device is true and reliable; moreover, the breathing rate of a patient can be known at any moment through waveform changes on a monitoring instrument, thereby reducing the anesthetic risk of the operation.
Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of end-tidal CO that is used for
2The CO that has oxygen therapy and collection breath concurrently of monitoring device
2Conduit is used in monitoring, is particularly suitable for using in non-tracheal intubation patient's anesthesia.
Background technology
Clinically, adopt the tracheal intubation control breathing usually for the general anesthesia patient, whether enough for understanding oxygen uptake at any time, need to use end-tidal CO
2Monitoring device such as Philip monitor or monitor are monitored in real time, and an end of tracheal intubation is connected with monitoring device by interface, in time adjust respiratory frequency by the variation of waveform on the monitor.End-tidal CO
2Monitoring is the important means of patient's vital sign monitoring in the anesthesia.Yet the general anesthesia patient for non-tracheal intubation only monitors breath state with blood oxygen saturation usually.Because intravenous anesthetic all has inhibitory action to patient's breathing, and blood oxygen saturation has hysteresis, can not in time reflect whether anoxia of patient, even under the situation of severe depletion of oxygen, patient is suppressed owing to breathing, also can't alleviate anoxia, even the phenomenon of respiratory arrest occur and can not find in time that this is breakneck by autonomous respiration.But should oxygen uptake monitor end-tidal CO again in the unresolved so far non-tracheal intubation corrective surgery
2Appropriate device.
Summary of the invention
The purpose of this utility model is to utilize existing end-tidal CO
2Monitoring device provides a kind of end-tidal CO that has oxygen therapy concurrently and collect breath
2Conduit is used in monitoring, can effectively monitor end-tidal CO in oxygen uptake
2, ensure medical safety.
This utility model is regulated sleeve pipe, oxygen cylinder joint and monitoring device joint by oxygen delivery tube, breath collecting duct, conduit connection tube, catheter length and is formed.During the centre of conduit connection tube is provided with every, in every the left and right sides be respectively equipped with a nostril intubate, the two ends of conduit connection tube are connected with an end of oxygen delivery tube and breath collecting duct respectively; The other end of oxygen delivery tube and oxygen cylinder dovetail connector, the interface of this oxygen cylinder joint and oxygen cylinder is complementary; The other end of breath collecting duct and monitoring device dovetail connector; This monitoring device joint and end-tidal CO
2The interface of monitoring device is complementary; Catheter length is regulated sleeve pipe 4 and is placed in oxygen delivery tube and makes two circumferences of cannon bone become loop overlapping shape outward with the breath collecting duct, and the slip that the size of ring set is regulated sleeve pipe 4 by catheter length is regulated, so that adjusting elasticity when two pipes are placed in left and right sides ear respectively.
During use, two nostril intubate are inserted nostril, the left and right sides respectively, medical glass oxygen cylinder interface set on the oxygen cylinder joint of oxygen delivery tube and the wall is connected, breath collecting duct joint and end-tidal CO
2The monitoring device interface is connected, and two conduits are placed in left and right sides ear respectively and regulate elasticity with the length adjustment sleeve pipe, just can open the oxygen uptake of oxygen cylinder switch routinely, opens end-tidal CO
2Monitoring device monitoring end-tidal CO
2Since during the centre of conduit connection tube is provided with every, the oxygen in the oxygen delivery tube can not influence the composition and the concentration of gas in the breath collecting duct, makes end-tidal CO
2The real result that monitoring device detects is reliable, and grasps patient's respiratory frequency at any time by the variation of waveform on the monitor, thereby has reduced the risk of surgery anesthesia.
This utility model is simple in structure, and is with low cost, easy to use, can effectively monitor end-tidal CO in patient's oxygen uptake
2, grasp patient's respiratory frequency at any time, thereby can effectively reduce the risk of surgery anesthesia.

The specific embodiment
Now in conjunction with the accompanying drawings this utility model is described in detail.
This utility model is regulated sleeve pipe 4, oxygen cylinder joint 5 and monitoring device joint 6 by oxygen delivery tube 1, breath collecting duct 2, conduit connection tube 3, catheter length and is formed, during the centre of conduit connection tube 3 is provided with every 7, in every the left and right sides be respectively equipped with a nostril intubate 8, one end of oxygen delivery tube and breath collecting duct is connected by conduit connection tube 3, the other end of oxygen delivery tube is connected with oxygen cylinder joint 5, and the other end of breath collecting duct is connected with monitoring device joint 6; Catheter length is regulated sleeve pipe 4 and is placed in that oxygen delivery tube 1 and breath collecting duct 2 are outer to make two circumferences of cannon bone become loop overlapping shape, and the slip that the size of ring set is regulated sleeve pipe 4 by catheter length is regulated, so that adjusting elasticity when two pipes are placed in left and right sides ear respectively.
This utility model can be according to end-tidal CO
2Monitoring device and oxygen cylinder different are installed different oxygen cylinder joints and monitoring device joint, and are made different specifications and models as required.
