Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of anesthetic gases constant voltage conveyer device specifically.
Background technology
The anesthetic machine that suction-type anesthesia surgery uses is transported to breathing mask after anaesthetic gas and vapor permeation oxygen participant sent out, by breathing the effect reaching anesthesia.Because anaesthetic has certain side effect to the mankind, therefore in anaesthesia process, require the dosage accurately controlling anaesthetic, the output concentration of accurate control anaesthetic is except relevant with the precision of anaesthetic vaporizer, also relevant with the pipage control pipeline of anesthetic gases and oxygen, the output concentration of anaesthetic is directly connected to as the pressure of the oxygen of carrier and flow velocity.Existing suction type anaesthetic machine can only control the output pressure of oxygen and the evaporation rate of anaesthetic respectively, and be difficult to harmonious between the two, the final output concentration of anaesthetic is difficult to accurate control.
Summary of the invention
This utility model is solve the problem to provide the anesthetic gases constant voltage conveyer device that simple, easy to use, the accurate control anaesthetic of a kind of structure exports concentration.
The technical scheme that this utility model adopts for technical solution problem is as follows:
Anesthetic gases constant voltage conveyer device described in the utility model comprises gas mixing tube, the breathing mask of gas mixing tube outfan is connected to by appendix, described gas mixing tube is with oxygen input and anesthetic gases input, described oxygen input and anesthetic gases input are all connected on voltage balancer by pipeline, described voltage balancer is the tubular structures of two ends with end cap, the two ends of voltage balancer are respectively arranged with oxygen input tube and anesthesia gas input pipe, slide in the inner chamber of voltage balancer and be provided with slip plunger, described slip plunger is between oxygen input tube and anesthesia gas input pipe, the voltage balancer tube wall of slip plunger both sides is provided with oxygen output tube and anesthesia gas outlet tube, described oxygen output tube and oxygen input tube are positioned at the same side of slip plunger, anesthesia gas outlet tube is positioned at the same side of slip plunger with anesthesia gas input pipe, described oxygen output tube is connected with the oxygen input of gas mixing tube, described anesthesia gas input pipe is connected with anesthetic gases input.
Arrange sealed plunger and spring respectively at the two ends of voltage balancer inner chamber, described spring, between sealed plunger and end cap, described end cap is provided with spiracle.
Owing to have employed said structure, this anesthetic gases constant voltage transport conveyor constructions is simple, easy to use, the pressure of the balanced oxygen of energy and anaesthetic, thus accurately controls anaesthetic output concentration, reaches the anaesthetic effect of controllable precise.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
As shown in Figure 1, anesthetic gases constant voltage conveyer device described in the utility model is comprised gas mixing tube 1, is connected to the breathing mask 3 of gas mixing tube 1 outfan by appendix 2, described gas mixing tube 1, with oxygen input and anesthetic gases input, passed through appendix 2 after the oxygen of oxygen input and the input of anesthetic gases input and anaesthetic mix in gas mixing tube 1 and was transported to breathing mask 3.
Described oxygen input and anesthetic gases input are all connected on voltage balancer by pipeline, described voltage balancer is the tubular structures of two ends with end cap, the two ends of voltage balancer are respectively arranged with oxygen input tube 4 and anesthesia gas input pipe 5, connect oxygen generator and anaesthetic vaporizer respectively by check valve.Slide in the inner chamber of voltage balancer and be provided with slip plunger 6, described slip plunger 6 is between oxygen input tube 4 and anesthesia gas input pipe 5, the voltage balancer tube wall of slip plunger 6 both sides is provided with oxygen output tube 7 and anesthesia gas outlet tube 8, described oxygen output tube 7 and oxygen input tube 4 are positioned at the same side of slip plunger 6, anesthesia gas outlet tube 8 is positioned at the same side of slip plunger 6 with anesthesia gas input pipe 5, described oxygen output tube 7 is connected with the oxygen input of gas mixing tube 1, and described anesthesia gas input pipe 5 is connected with anesthetic gases input.
Voltage balancer inner chamber is separated into two independently bins by slip plunger 6, slip plunger 6, between two bins, plays the effect of even two bin pressure, time any one bin pressure is larger, slip plunger 6 is just slided, until both sides pressure is consistent to opposite side.In order to make slip plunger 6 can slippage and keep good sealing in voltage balancer inner chamber, in slip plunger 6, sealing ring can also be set between voltage balancer inwall.
In addition, arrange sealed plunger 9 and spring 10 at the two ends of voltage balancer inner chamber respectively, described spring 10, between sealed plunger 9 and end cap, described end cap is provided with spiracle.This sealed plunger 9 can make the end of voltage balancer have certain flexible ability to keep excellent sealing simultaneously, be conducive to the balance of slip plunger 6 pressure at both sides.
During use, the anaesthetic of oxygen and evaporation enters the both sides of slip plunger 6 in voltage balancer respectively by oxygen input tube 4 and anesthesia gas input pipe 5, under the regulating action of slip plunger 6, slip plunger 6 both sides pressure keep balance, oxygen all after pressure and anaesthetic are transported to gas mixing tube 1 respectively by oxygen output tube 7 and anesthesia gas outlet tube 8, in gas mixing tube 1, be transported to breathing mask 3 after mixing.
