Abstract
The utility model provides an anesthetic gas output concentration control device of an anesthesia machine. The anesthetic gas output concentration control device of the anesthesia machine comprises a three-way pipe and a valve body, wherein the three-way pipe comprises an oxygen inlet, an anesthetic gas inlet and an anesthetic mixed gas outlet. An anesthetic gas spray pipe is arranged on the valve body, and at least one through hole communicated with an inner cavity of the spray pipe is formed in the pipe wall of the anesthetic gas spray pipe. One end of the anesthetic gas spray pipe is fixedly connected with the valve body and is communicated with an inner cavity of the valve body, and the other end of the anesthetic gas spray pipe is provided with a pressure buffer plate which is perpendicular to the anesthetic gas spray pipe along the axial direction. The area of the pressure buffer plate is larger than the cross-sectional area of the anesthetic gas spray pipe. The valve body is connected with the three-way pipe through a connecting pipe, the anesthetic gas spray pipe on the valve body and the anesthetic gas inlet on the three-way pipe are all placed in the connecting pipe, a gap reserved between the valve body, the three-way pipe and the connecting pipe is sealed by a sealing ring.
Description
Technical field
This utility model belongs to field of medical, relates to a kind of gas circuit structure of suction type anaesthetic machine, particularly keeps the protector of anesthetics output concentration stabilize during the quick oxygen supply of a kind of anesthetic machine.
Background technology
Anesthetic machine is mainly used in the suction-type surgery anesthesia clinically, and its principle is to utilize oxygen to make anaesthetic volatilization by the anaesthetic vaporizer, produces oxygen and the mist of anaesthetic, will input to patient with the mist of anaesthetic, makes patient be in narcotism.Because anaesthetic has certain side effect to the mankind, so it is significant for patient's anaesthetic effect accurately to control anesthetic machine anaesthetic output concentration.Accurately the anaesthetic output concentration of control anesthetic machine except and outside the Pass the precision of anaesthetic vaporizer has, also and the control gas circuit of anesthetic machine direct relation is arranged.In the control gas circuit of anesthetic machine, larger to the pressure influence of anaesthetic vaporizer outfan during owing to quick oxygen supply, so oxygen supply is maximum to the output concentration affects of anaesthetic vaporizer fast.Prior art is to utilize venturi principle (schematic diagram is seen Fig. 1), anaesthetic vaporizer outfan produced negative pressure when its shortcoming was quick oxygen supply, the low about 10kPa of the pressure of (oxygen supply is closed fast) during than normal operation, so that vaporizer moment output concentration increases, affect patient's anaesthetic effect.Eliminate quick oxygen supply to anaesthetic vaporizer output concentration as influencing factor, key is the variation of anaesthetic vaporizer output end pressure when eliminating quick oxygen supply.
Summary of the invention
The purpose of this utility model namely is the defective for present anesthetic machine control gas circuit, and a kind of anesthetic machine anesthetic gases output concentration control apparatus is provided, and keeps anesthetics output concentration stabilize when the quick oxygen supply of anesthetic machine.
The technical solution of the utility model is as follows:
A kind of anesthetic machine anesthetic gases output concentration control apparatus is characterized in that: comprise a tee T and a valve body, described tee T comprises an oxygen inlet, an anesthetic gases import, an anesthesia mixed gas outlet; Be provided with the anesthetic gases jet pipe on the described valve body, the through hole that has at least one to communicate with the jet pipe inner chamber on the tube wall of described anesthetic gases jet pipe; Described anesthetic gases jet pipe one end is fixedly connected with valve body and communicates with body cavity, the other end arrange one with the axial vertical pressure buffer sheet of anesthetic gases jet pipe, the area of described pressure buffer sheet is greater than the cross-sectional area of described anesthetic gases jet pipe; Described valve body is connected by connection tube with tee T, and the anesthetic gases jet pipe on the valve body and the anesthetic gases import on the tee T all are positioned at connection tube, and the slit between valve body and tee T and the connection tube seals by sealing ring.
This utility model can be eliminated the impact of anaesthetic vaporizer output end pressure when quick oxygen supply, keeps the stable of anesthetic gases output concentration, and patient is shielded.

The specific embodiment
As shown in Figure 2, this utility model comprises a tee T 1 and a valve body 2, and described tee T 1 comprises an oxygen inlet 11, an anesthetic gases import 12, an anesthesia mixed gas outlet 13; Be provided with anesthetic gases jet pipe 3 on the described valve body 2, the through hole 31 that has at least one to communicate with the jet pipe inner chamber on the tube wall of described anesthetic gases jet pipe 3; Described anesthetic gases jet pipe 3 one ends are fixedly connected with valve body 2 and communicate with the inner chamber of valve body 2, the other end arrange one with the axial vertical pressure buffer sheet 4 of anesthetic gases jet pipe, the area of described pressure buffer sheet 4 is greater than the cross-sectional area of described anesthetic gases jet pipe 3; Described valve body 2 is connected by connection tube 5 with tee T 1, and the anesthetic gases jet pipe 3 on the valve body 2 all is positioned at connection tube 5 with the anesthetic gases import 12 on the tee T 1, and the slit between valve body and tee T and the connection tube is by sealing ring 6 sealings.
This utility model in anesthetic machine gas circuit shown in Figure 1, replaces wherein venturi valve with this utility model in use, and gas flow is shown in the direction of arrow among Fig. 2.Oxygen enters tee T by the oxygen inlet 11 of tee T 1, the anesthetic gases of anaesthetic vaporizer outfan output is by through hole 31 outputs of valve body 2 on jet pipe 3, walk around pressure buffer sheet 4, anesthetic gases import 12 on tee T 1 enters tee T again, with after the oxygen mix by the output of anesthesia mixed gas outlet 13.This utility model can keep anesthetics output concentration stabilize because the effect of pressure buffer sheet 4 is very little on the impact of anaesthetic vaporizer output end pressure when quick oxygen supply.
