The evaporator for medicine liquid 100 according to the embodiment of the present invention is specifically described below in conjunction with accompanying drawing.
As shown in Figures 1 to 7, body 10, vaporization chamber 21, medicated core 22 and volume control device 31 is comprised according to the evaporator for medicine liquid of the embodiment of the present invention.Wherein, body 10 is provided with air inlet 11 and gas outlet 12, is limited with the first gas circuit 20 and the second gas circuit 30 be located between air inlet 11 and gas outlet 12 in body 10.Vaporization chamber 21 is located in body 10, holds medicinal liquid in vaporization chamber 21, the first gas circuit 20 through vaporization chamber 21 to take the medicinal liquid in vaporization chamber 21 out of gas outlet 12.Medicated core 22 to be located in the first gas circuit 20 and to be positioned at vaporization chamber 21.Volume control device 31 is located in the second gas circuit 30 to control the flow of gas in the second gas circuit 30.
Thus, according to the evaporator for medicine liquid 100 of the embodiment of the present invention, by arranging volume control device 31 in the second gas circuit 30, can make by the gas flow in the second gas circuit 30 more steady, when discharging from gas outlet 12 after the gas and vapor permeation on the liquid steam in the first gas circuit 20 and the second gas circuit 30, the discharge stability of the mist exported from gas outlet 12 is improved, and the flow of mist exported and the flow of pressure curve and liquid steam and pressure curve matching degree high, thus the flow accuracy of admixing medical solutions gas and stability are improved.
Evaporator for medicine liquid in correlation technique can be used for evaporation to anesthetic liquid medicine and control, and the live gas entered from air inlet is divided into two-way, and a road is called carrier gas, and another road is called bypass gas.Carrier gas and bypass gas mix in gas outlet and export admixing medical solutions gas.The volume control device of this anesthesia evaporator is located in carrier gas gas circuit, and the gas in carrier gas gas circuit is by passing through volume control device again after vaporization chamber.The control of the admixing medical solutions gas concentration that gas outlet exports mainly relies on and regulates the output of the liquid steam in carrier gas gas circuit to realize.This kind of regulative mode makes the flow of the admixing medical solutions gas of output and the flow of pressure curve and liquid steam and pressure curve matching degree low, and the precision of the concentration of the admixing medical solutions gas of output is not high.If different from the flow of air inlet input live gas, the concentration of the admixing medical solutions gas exported also can be caused unstable, and therefore it is poor to the change adaptability of fresh gas flow, and the admixing medical solutions gas concentration stability of output is not high.
And according to the evaporator for medicine liquid 100 of the embodiment of the present invention, as shown in Figure 3, the first gas circuit 20 is carrier gas gas circuit, the second gas circuit 30 is bypass gas circuit.Volume control device 31 is located in the second gas circuit 30, is controlled by the flow of the volume control device 31 in the second gas circuit 30 to the second gas circuit 30.In other words, namely volume control device 31 is located in bypass gas circuit, and controls the flow of bypass gas.This evaporator for medicine liquid 100 improves flow and the pressure curve of the admixing medical solutions gas of output, increase the flow of admixing medical solutions gas and the flow of pressure curve and liquid steam and the matching degree of pressure curve that export in gas outlet 12, make the precision of the concentration of admixing medical solutions gas higher.And the adaptability that can improve fresh gas flow change, the stability of concentration of the admixing medical solutions gas of output is improved.
According to one embodiment of present invention, volume control device 31 comprises valve seat 311 and upper valve block 312.Wherein, the side of valve seat 311 is provided with the second liquid passage inlet 3111, and the opposite side of valve seat 311 is provided with the second gas circuit outlet.Upper valve block 312 is pivotably mounted on valve seat 311 along its axis, and the lower surface of upper valve block 312 is provided with the arcuate groove 3121 coaxial with upper valve block 312.Arcuate groove 3121 exports conducting with the second liquid passage inlet 3111 and the second gas circuit respectively, and the degree of depth that arcuate groove 3121 passes through increases gradually.
Particularly, as shown in Figure 4 and Figure 5, the arrow wherein in Fig. 4 shows the flow direction of gas.Upper valve block 312 is provided with arcuate groove 3121, and the axis that the degree of depth of arcuate groove 3121 extends along it at upper valve block 312 increases gradually or reduces.Be groove depth place 31211 in one end of arcuate groove 3121, the other end is the shallow place 31212 of groove.Groove depth place 31211 and the shallow place 31212 of groove and the second liquid passage inlet 3111 and the second gas circuit go out interruption-forming can the gas passage that passes through of supplied gas.By the rotation to upper valve block 312, the sectional area in the gap between valve seat 311 and upper valve block 312 increases or reduces, and namely bypass gas is increased by the sectional area of gas passage or reduces.
Wherein, the position at axis place of upper valve block 312 pivotable and the position at the axis place of arcuate groove 3121, that is, the pivotal axis of upper valve block 312 and the dead in line of arcuate groove 3121.Distance between distance between this axis position to the second liquid passage inlet 3111 exports with to the second gas circuit is equal, and this distance equals the radius of arcuate groove 3121.When volume control device 31 needs gas communication, arcuate groove 3121 exports conducting with the second liquid passage inlet 3111 and the second gas circuit all the time in the process of rotating along its axis, thus ensures the circulation of gas in volume control device 31.
Thus, in rotation, valve block 312 can change the sectional area of bypass gas by gas passage, thus the flow of bypass gas is changed, and realize the control to bypass gas flow, control procedure is simple; And mix with the liquid steam in the first gas circuit 20 through the bypass gas of volume control device 31, the admixing medical solutions gas of concentration stabilize can be exported in gas outlet 12.

As shown in Figure 6, according to one embodiment of present invention, evaporator for medicine liquid also comprises vapour lock 23, and vapour lock 23 to be located in body 10 and between vaporization chamber 21 and gas outlet 12.Particularly, vapour lock 23 is arranged in the first gas circuit 20, and namely vapour lock 23 is arranged in carrier gas gas circuit.
Thus, the liquid steam exported from vaporization chamber 21 passes through vapour lock 23, the discharge stability of liquid steam can be improved, thus the stability of the flow-pressure diagram of liquid steam output is enhanced, the flow-pressure diagram of liquid steam can not be made to occur the point rising suddenly or plunge, thus be stabilized in the output concentration of the admixing medical solutions gas that gas outlet 12 exports; But also the vapour lock 23 that can resistance be used different in evaporator for medicine liquid 100, to make the flow of medicinal liquid gas regulate, thus the flow of auxiliary adjustment medicinal liquid gas.
The structure of vapour lock 23 can be multiple, and alternatively, according to one embodiment of present invention, vapour lock 23 comprises multiple metallic screen stratum reticulare arranged of fitting successively.Thus, can determine the resistance of vapour lock 23 according to the screen cloth number of plies and sieve number, the drag parameter of vapour lock 23 regulates simple.
In addition, vapour lock 23 also can be made up of a folding screen cloth, and the material of screen cloth is not limit.Or vapour lock 23 is the devices be made up of the cylinder of different pore size, thus the resistance of vapour lock 23 can be arranged as required, when the vapour lock 23 that gas is consisted of the cylinder of different pore size, the flow of gas can be more stable.
According to the evaporator for medicine liquid 100 of the embodiment of the present invention, first gas circuit 20 is provided with vapour lock 23, second gas circuit 30 is provided with volume control device 31, namely in carrier gas gas circuit, be provided with vapour lock 23, bypass gas circuit arranges volume control device 31, and volume control device 31 has carried out effectively being combined with vapour lock 23.Utilize the flow of the volume control device 31 pairs of bypass gas in the second gas circuit 30 to control, and the vapour lock 23 in the first gas circuit 20 regulate the flow of the liquid steam in carrier gas gas circuit.This is auxiliary air-channel system based on the control of the first gas circuit 20, the second gas circuit 30 control, namely volume control device 31 and vapour lock carry out the air-channel system of Collaborative Control, optimize the flow-pressure diagram of the gas of the first gas circuit 20 and the second gas circuit 30, improve the characteristic stationarity of flow pressure of air-flow, improve the precision and stability that medicinal liquid gas exports.
According to one embodiment of present invention, evaporator for medicine liquid 100 also comprises temperature-sensing valve 32, and temperature-sensing valve 32 is located in the second gas circuit 30 to control the flow velocity of gas in the second gas circuit 30.Thus, temperature-sensing valve 32 can make the flow velocity of the medicinal liquid gas of output can not change because of the change of temperature and flow, thus the concentration of the medicinal liquid gas exported is more stable.
Particularly, as shown in Figure 7, according to one embodiment of present invention, temperature-sensing valve 32 comprises base plate 321, valve seat of temperature control valve 322, spring leaf 324 and portable plate 325.Wherein, valve seat of temperature control valve 322 to be located on base plate 321 and and limit a room 323 between base plate 321, valve seat of temperature control valve 322 is provided with and the air inlet 3231 of a room 323 conducting and venthole 3232.Spring leaf 324 to be located in a room 323 and to be arranged in valve seat of temperature control valve 322.One end of portable plate 325 is connected with spring leaf 324, and the other end of portable plate 325 is changeable between primary importance 3251 and the second position 3252.When portable plate 325 is positioned at primary importance 3251, the upper surface laminating valve seat of temperature control valve 322 of portable plate 325, when portable plate 325 is positioned at the second position 3252, forms the gap A with venthole 3232 conducting between the upper surface of portable plate 325 and valve seat of temperature control valve 322.
Thus, temperature-sensing valve 32 can realize controlling the switching of portable plate 325 between primary importance 3251 and the second position 3252, namely temperature-sensing valve 32 can the aperture size of control gap A, thus control the flow of the bypass gas of the second gas circuit outlet output of temperature-sensing valve 32, control procedure is simple and reliable, and the compact conformation of temperature-sensing valve 32.
Be understandable that, the shape of parts such as portable plate 325, valve seat of temperature control valve 311 of temperature-sensing valve 32 and the mode of connection do not limit, as long as temperature-sensing valve 32 can meet the condition of the aperture size of control gap A.
Specifically describe the operation principle of temperature-sensing valve 32 when gas flow and temperature change and process below.Arrow in Fig. 7 shows the flow direction of gas, and when bypass gas to flow between temperature-sensing valve 32 in room 323 through the second gas circuit 30 from air inlet 3231, bypass gas flows to venthole 3232 by the gap A in temperature-sensing valve 32, then flows out from venthole 3232.
When the flow of live gas increases, live gas is also increased accordingly by the flow of the second gas circuit 30, the bypass gas pressure increase between inflow in room 323, and the pressure now acted on outside portable plate 325 also increases.Under the effect of outside pressure, the portable plate 325 be fixed on spring leaf 324 is partial to the internal face of valve seat of temperature control valve 322, namely primary importance 3251 is partial to, the aperture of the gap A between valve seat of temperature control valve 322 and portable plate 325 is reduced, and the spacing namely between the internal face of valve seat of temperature control valve 322 and portable plate 325 reduces.The gas flow flowing into the air inlet 3231 of temperature-sensing valve 32 reduces, and the flow of the bypass gas in the second gas circuit 30 is adjusted.Thus achieving when fresh gas flow is larger, the adjustment of the concentration of the admixing medical solutions gas exported from gas outlet 12, the concentration of the admixing medical solutions gas that gas outlet 12 is exported is more stable.
When the flow of live gas reduces, the pressure of the bypass gas between inflow in room 323 reduces, and the pressure now acted on portable plate 325 also reduces.Portable plate 325, under the rebound effect of spring leaf 324, makes the aperture of the gap A between portable plate 325 and valve seat of temperature control valve 322 increase, i.e. spacing between the internal face of portable plate 325 and valve seat of temperature control valve 322 increases.The gas flow flowed in air inlet 3231 increases, and the output flow of the bypass gas of the second gas circuit 30 is adjusted.Thus achieve when live gas low discharge, make the concentration of the admixing medical solutions gas exported from gas outlet 12 more stable.
