Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with accompanying drawing, the invention will be further described, as depicted in figs. 1 and 2, usual vaporizer comprises fresh gas inlet 1, pressure compensation unit 2, live gas stop valve 3, fuse 4, bypass 5, temperature compensation unit 6, concentration control unit 7, mixed gas outlet 8 and vaporization chamber 10.Pressure compensation unit 2 is for carrying out pressure compensation, and it can prevent back flow of gas when mixed gas outlet 8 is in pressure change, and is in stabilizing gas flow velocity when pressure changes at fresh gas inlet 1.Vaporization chamber 10 is the containers for storing anesthetic liquid medicine with diapire.Fuse 4 is placed in the inside of vaporization chamber 10, and a part for fuse 4 is immersed in anesthetic liquid medicine, makes anesthesia liquid can at fuse 4 vertical spread, and fuse 4 can promote that the anesthetic liquid medicine in vaporization chamber flashes to gaseous state by liquid, and its surface area is larger, then evaporation effect is good.
As shown in Figure 3 and Figure 4, fuse 4 comprises the fuse pipeline 45 of core print seat 41 and tool square hollow structure, and fuse pipeline 45 is arranged on core print seat 41.Fuse pipeline 45 is fixed on outside core print seat 41 along spiral helicine the spiraling of circumference of core print seat 41, and in the present embodiment, the cross section of core print seat 41 is circular.Temperature compensation unit 6 is placed in the center of core print seat 41, and core print seat 41 is also provided with annular chamber 48, during for entering fuse pipeline 45 when live gas, carries anaesthetic vaporizer gas and leaves vaporization chamber through the passage (not shown) of the annular chamber 48 of core print seat.Fuse pipeline 45 comprises spine skeleton and cotton, and spine skeleton parcel is formed fuse pipeline 45 by cotton, and backbone frame is played a supporting role, and fuse pipeline 45 can not be blocked because cotton subsides.In order to make fuse pipeline 45 for square hollow structure, spine skeleton adopts square spring, thus forms the fuse pipeline 45 of square hollow, can realize maximizing at less space lower channel, strengthen the free air space of anesthesia steam, the anesthesia steam of more high concentration can be provided faster.
Fuse 4 can be made into the structure of core print seat 41 and fuse pipeline 45 one, such as, be weldingly fixed on core print seat 41 by fuse pipeline 45.Also detachable structure of installing can be made, as being fixed on dismountable for fuse pipeline on core print seat 41 by fuse.Concrete dismountable fixing can adopt steady pin, and core print seat 41 and fuse pipeline 45 are provided with installing hole, realizes dismountable fixing by steady pin with coordinating of installing hole.Also can adopt screw, core print seat 41 and fuse pipeline 45 are provided with screwed hole, by coordinating of screw and screwed hole, realize the detachable installation of core print seat 41 and fuse pipeline, certainly, also can adopt other detachable fixed forms.
The preferred embodiment of the present invention is, installing hole is provided with in one end of fuse pipeline 45, the core print seat 41 corresponding with the installing hole of fuse pipeline 45 is provided with mounting groove (not shown), steady pin 46 inserts mounting groove through installing hole, be fixed on one end of fuse pipeline 45 on core print seat 41, then fuse pipeline 45 is arranged on core print seat 41 around the circumferential edges helical form of core print seat.Fuse pipeline 45 is fixed on core print seat 41 by the other end stator 47 of fuse pipeline 45.Be specially, in the bottom of fuse pipeline 45, stator 47 be installed, core print seat 41 is provided with screwed hole, by screw, stator 47 is fixed on core print seat 41, thus fuse pipeline 45 is fixed on core print seat 41.
As shown in Figure 5, stator 47 is flat circulus to the structure of stator 47, and on the ring of stator 47, symmetry has two screwed holes 472, for stator 47 is fixed on core print seat 41.The periphery of stator 47 also has outwardly ear 473 and claw 474, and ear 473 is semicircle shape, for when fuse pipeline 45 is fixed on core print seat 41, pushes 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 the effect pushing down fuse pipeline 45 simultaneously, meanwhile, can also prevent fuse pipeline 45 radial development.
As shown in Figure 4, when being fixed on core print seat 41 by fuse pipeline 45, also outside fuse pipeline 45, be provided with outer cotton core 43, inner side is provided with internal layer cotton core 44.Outer cotton core 43 and internal layer cotton core 44 have same structure, but size is different, and outer cotton core 43 can be made to be adjacent to the outside of fuse pipeline 45, and internal layer cotton core 44 is adjacent to the inner side of fuse pipeline 45.As shown in Figure 4 and Figure 6, inside and outside layer cotton core is cylindric to the structure of internal layer cotton core 44 and outer cotton core 43, and in other embodiments, inside and outside layer cotton core also can be the column of other cross sectional shape.One end of inside and outside layer cotton core offers breach 442 and forms internal layer shirt rim 441 and outer shirt rim 431, and the height of the breach 442 of inside and outside layer cotton core equals the height of fuse pipeline 45 just.The quantity of breach 442 can set as required, and the breach 442 of the inside and outside layer cotton core in the present embodiment has three, and thus inside and outside layer cotton core has three shirt rims respectively.Stator 47 is positioned at the circumference of internal layer cotton core 44, and the claw 474 of stator and ear 473 push down fuse pipeline respectively on the breach 442 of internal layer cotton core, prevents fuse pipeline 45 radial development.Stagger successively in the internal layer shirt rim 441 of internal layer cotton core and the outer shirt rim 431 of outer cotton core, when fuse is placed in vaporization chamber, the internal layer shirt rim 441 of internal layer cotton core and the outer shirt rim 431 of outer cotton core are deeply evaporated downwards bottom medicinal liquid, because fuse pipeline 45 and inside and outside layer cotton core are all use cotton to make, therefore, even if when anesthetic liquid medicine is little, anesthetic liquid medicine also can pass through the shirt rim of internal layer cotton core 44 and outer cotton core 43 to vertical spread.The material of cotton can be polyethylene, polypropylene.The mixing coenobium of politef or other fibrous materials.In evaporation process, be converted into the anesthesia steam of high concentration, exported by fuse pipeline 45.
Near steady pin 46 mounting groove of core print seat 41, air feed flows to the pore (not shown) into fuse pipeline in addition, when fuse is placed in vaporization chamber, fresh gas flow enters fuse pipeline 45 through blowhole, because the shirt rim of anesthetic liquid medicine by inside and outside layer cotton core is absorbed by fuse, under the effect of evaporation, liquid becomes gas, is full of anesthesia gas in fuse pipeline 45.After live gas enters fuse pipeline 45, gas flows in fuse pipeline 45, and carry a large amount of evaporation gases and flow out from the end of fuse pipeline 45, and the passage (not shown) through core print seat 41 annular chamber place 48 leaves vaporization chamber, enters concentration control unit.
Anesthesia evaporator fuse of the present invention is made up of core print seat and fuse pipeline, and fuse pipeline is by steady pin and stator is dismountable is fixed on core print seat, and fuse pipeline wraps up square spring by cotton and forms.The processing cost of fuse is low, processes simple and easy for installation.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
