Back flow of gas and the stabilizing gas flow velocity when fresh gas inlet 1 is in pressure change are prevented during in pressure change.Vaporization chamber
10 be the container for being used to store anesthetic liquid medicine with bottom wall.Fuse 4 is placed in the inside of vaporization chamber 10, the part leaching of fuse 4
Bubble is in anesthetic liquid medicine, and alloing anesthesia liquid, fuse 4 can promote the anesthetic liquid medicine in vaporization chamber by liquid in 4 vertical spread of fuse
Gaseous state is flashed to, surface area is bigger, then evaporation effect is good.
As shown in Figure 3 and Figure 4, fuse 4 includes core print seat 41 and has the fuse pipeline 45 of square hollow structure, fuse pipeline 45
On core print seat 41.Spiral helicine spiral of the circumferential direction of fuse pipeline 45 along core print seat 41 is fixed on 41 outside of core print seat, the present embodiment
In, the cross section of core print seat 41 is circle.Temperature compensation unit 6 is placed in the center of core print seat 41, and core print seat 41 is additionally provided with annular chamber 48,
For when live gas enters fuse pipeline 45, carrying the channel (not shown) of annular chamber 48 of the anaesthetic vaporizer steam through core print seat
Leave vaporization chamber.Fuse pipeline 45 includes spine skeleton and cotton, and spine skeleton is wrapped up and forms fuse pipeline 45 by cotton, ridge
Beam framework is played a supporting role so that fuse pipeline 45 will not block due to cotton collapses.In order to which fuse pipeline 45 is made to be rectangular
Hollow structure, spine skeleton use rectangular spring, so as to form the fuse pipeline 45 of square hollow, can realize in smaller space
Lower channel maximizes, and increases the free air space of anesthesia steam, can provide the anesthesia steam of more high concentration faster.
Fuse 4 can be made into the structure of 45 one of core print seat 41 and fuse pipeline, such as fuse pipeline 45 is welded and fixed
On core print seat 41.Can also fuse the structure detachably installed is made, such as fuse pipeline is detachably mounted on core print seat 41.
Fixed pin may be used in specific dismountable fixation, and mounting hole is equipped on core print seat 41 and fuse pipeline 45, by fixed pin with
The cooperation of mounting hole is realized dismountable fixed.Screw can also be used, threaded hole is equipped on core print seat 41 and fuse pipeline 45,
By the cooperation of screw and threaded hole, the detachable installation of core print seat 41 and fuse pipeline is realized, it is of course also possible to use other can
Dismantle fixed form.
The preferred embodiment of the present invention is to be equipped with mounting hole, the peace with fuse pipeline 45 in one end of fuse pipeline 45
It fills the corresponding core print seat 41 in hole and is equipped with mounting groove (not shown), fixed pin 46 passes through mounting hole to be inserted into mounting groove, by fuse pipe
The one end in road 45 is fixed on core print seat 41, and then fuse pipeline 45 is mounted on core print seat 41 around the circumferential edges helical form of core print seat
On.Fuse pipeline 45 is fixed on core print seat 41 by the other end fixinig plate 47 of fuse pipeline 45.Specifically, in fuse pipeline 45
Bottom fixinig plate 47 is installed, on core print seat 41 be equipped with threaded hole, fixinig plate 47 is fixed on core print seat 41 by screw, from
And fuse pipeline 45 is fixed on core print seat 41.
The structure of fixinig plate 47 is as shown in figure 5, fixinig plate 47 is flat cyclic structure, on the ring of fixinig plate 47 symmetrically
There are two threaded hole 472, for fixinig plate 47 to be fixed on core print seat 41.There is the ear outwardly protruded the periphery of fixinig plate 47
473 and claw 474, ear 473 is semicircle shape, for when fuse pipeline 45 is fixed on core print seat 41, pushing down fuse pipeline 45.
Claw 474 is claw-like structures, when fuse pipeline 45 is installed on core print seat 41, can not only play simultaneously and push down fuse pipeline 45
Effect, simultaneously, additionally it is possible to prevent 45 radial development of fuse pipeline.
As shown in figure 4, when fuse pipeline 45 is fixed on core print seat 41, outer layer also is installed in 45 outside of fuse pipeline
Cotton core 43, inside are equipped with internal layer cotton core 44.Outer layer cotton core 43 and internal layer cotton core 44 have same structure, but size differs
Sample, can make outer layer cotton core 43 be adjacent to the outside of fuse pipeline 45, and internal layer cotton core 44 is adjacent to the inside of fuse pipeline 45.Internal layer cotton core
44 and outer layer cotton core 43 structure as shown in Figure 4 and Figure 6, inside and outside layer cotton core is cylindric, in other embodiments, inside and outside layer
Cotton core may be the column of other cross sectional shapes.One end of inside and outside layer cotton core opens up jagged 442 and forms internal layer shirt rim
441 and outer layer shirt rim 431, the height of the notch 442 of inside and outside layer cotton core be exactly equal to the height of fuse pipeline 45.Notch 442
Quantity can be set as needed, and there are three the notches 442 of the inside and outside layer cotton core in the present embodiment, thus inside and outside layer cotton core is distinguished
There are three shirt rims.Fixinig plate 47 is located in the circumference of internal layer cotton core 44, and the claw 474 of fixinig plate and ear 473 are respectively in internal layer
Fuse pipeline is pushed down on the notch 442 of cotton core, prevents 45 radial development of fuse pipeline.The internal layer shirt rim 441 of internal layer cotton core and outer
The outer layer shirt rim 431 of layer cotton core is staggered successively, when fuse is placed in vaporization chamber, the internal layer shirt rim 441 of internal layer cotton core and outer
The outer layer shirt rim 431 of layer cotton core reaches deep down into evaporation liquid bottom, since fuse pipeline 45 and inside and outside layer cotton core are all to use cotton
Cloth is made, and therefore, even if in the case where anesthetic liquid medicine is seldom, anesthetic liquid medicine can also pass through internal layer cotton core 44 and outer layer cotton core
43 shirt rim is crept up.The material of cotton can be polyethylene, polypropylene.The mixing of polytetrafluoroethylene (PTFE) or other fibrous materials
Coenobium.In evaporation process, the anesthesia steam of high concentration is converted into, is exported by fuse pipeline 45.
46 mounting groove of fixed pin of core print seat 41 nearby also has gas supply stream into the stomata (not shown) of fuse pipeline, works as fuse
When being placed in vaporization chamber, fresh gas flow enters fuse pipeline 45 through blowhole, since anesthetic liquid medicine passes through inside and outside layer cotton core
Shirt rim is absorbed by fuse, and under the action of evaporation, liquid becomes steam, and anesthesia steam is full of in fuse pipeline 45.Work as virgin gas
After body enters fuse pipeline 45, gas flows in fuse pipeline 45, and carries a large amount of evaporation steam from fuse pipeline 45
End is flowed out, and leaves vaporization chamber through at 41 annular chamber of core print seat 48 channel (not shown), into concentration control unit.
The anesthesia evaporator fuse of the present invention is made of core print seat and fuse pipeline, and fuse pipeline passes through fixed pin and fixinig plate
It is detachably mounted on core print seat, fuse pipeline wraps up rectangular spring by cotton and forms.The processing cost of fuse is low, and processing is simple
It is and easy for installation.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
