Abstract
This utility model relates to a kind of medical apparatus and instruments, is a kind of suction-type anesthetic gases conveyer device specifically.Comprise gas mixer, be connected to the breathing mask of gas mixer outfan by appendix, gas mixer comprises the coaxial top tube, middle tube, and down tube arranged, appendix is connected to the outfan of lower pipe, the internal diameter that the internal diameter of middle pipe is less than pipe is also less than the internal diameter of lower pipe, the two ends of middle pipe connect top tube and down tube respectively by upper Taper Pipe, lower Taper Pipe, the upper end of upper pipe connects oxygen catheter by ring flange, the inner of oxygen catheter is arranged in the inner chamber of pipe, extends to the joining place of pipe and upper Taper Pipe, and the tube wall of upper pipe is communicated with anaesthetic carrier pipe.This suction-type anesthetic gases transport conveyor constructions is simple, easy to use, automatically can adjust the conveying capacity of anaesthetic according to the air velocity of oxygen delivery, thus accurately controls anaesthetic output concentration.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of suction-type anesthetic gases 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 suction-type anesthetic gases 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:
Suction-type anesthetic gases conveyer device described in the utility model comprises gas mixer, the breathing mask of gas mixer outfan is connected to by appendix, described gas mixer comprises the coaxial upper pipe arranged, middle pipe and lower pipe, described appendix is connected to the outfan of lower pipe, the internal diameter that the internal diameter of described middle pipe is less than pipe is also less than the internal diameter of lower pipe, the two ends of middle pipe are respectively by upper Taper Pipe, lower Taper Pipe connects top tube and down tube, the upper end of upper pipe connects oxygen catheter by ring flange, the external diameter of described oxygen catheter is less than the internal diameter of pipe, the inner of oxygen catheter is arranged in the inner chamber of pipe, extend to the joining place of pipe and upper Taper Pipe, the tube wall of upper pipe is communicated with anaesthetic carrier pipe, described anaesthetic carrier pipe is connected to the outfan of anaesthetic vaporizer.
Owing to have employed said structure, this suction-type anesthetic gases transport conveyor constructions is simple, easy to use, automatically can adjust the conveying capacity of anaesthetic according to the air velocity of oxygen delivery, thus accurately control anaesthetic output concentration, reach 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 mixer, is connected to the breathing mask 3 of gas mixing tube outfan by appendix 2, and oxygen and anaesthetic passed through appendix 2 and be transported to breathing mask 3 after mixing in gas mixer.
Described gas mixer comprises the coaxial upper pipe 4 arranged, middle pipe 5 and lower pipe 6, described appendix 2 is connected to the outfan of lower pipe 6, the internal diameter that the internal diameter of described middle pipe 5 is less than pipe 4 is also less than the internal diameter of lower pipe 6, the two ends of middle pipe 5 are respectively by upper Taper Pipe 7, lower Taper Pipe 8 connects upper pipe 4 and lower pipe 6, the upper end of upper pipe 4 connects oxygen catheter 9 by ring flange, the external diameter of described oxygen catheter 9 is less than the internal diameter of pipe 4, the inner of oxygen catheter 9 is arranged in the inner chamber of pipe 4, extend to the joining place of pipe 4 and upper Taper Pipe 7, the tube wall of upper pipe 4 is communicated with anaesthetic carrier pipe 10, described anaesthetic carrier pipe 10 is connected to the outfan of anaesthetic vaporizer.
During use, the anaesthetic of oxygen and evaporation enters respectively by oxygen catheter 9 and anaesthetic carrier pipe 10 in the inner chamber of upper pipe 4, because oxygen pressure is larger, flow velocity is very fast, form negative pressure at the peristome of upper Taper Pipe 7, the anaesthetic in anaesthetic carrier pipe 10 is sucked upper Taper Pipe 7, and the flow velocity of oxygen is faster, the negative pressure formed is lower, and the anaesthetic of suction is also more.Pipe 5 compression volume, raising flow velocity further in two kinds of mist warps, spray and enter lower pipe 6, in the inner chamber of lower pipe 6, space becomes suddenly large, and air-flow slows down, and makes oxygen and anaesthetic be able to abundant mixing, is transported to breathing mask 3 finally by appendix 2.
