Successively stage clip 308, bottom spool 305, pressure control spring 307, spring cover 306, upper valve core 304 are packed in the cavity of lower contact 303, upper valve core 304 is provided with the draw-in groove of a wiper seal circle 312, bottom spool 305 is provided with the draw-in groove of a wiper seal circle 314, and be coated with a little lubricating oil at 315,316,317 o'clock at dress wiper seal circle 312,314 and air flue sealing ring, prevent that air flue from leaking, be convenient to install and do not ground an ancient egg-shaped, holed wind instrument.Threaded engagement by top connection 302 and lower contact 303 is whole to constitute spool 300, an air flue sealing ring 313 is housed between when top connection 302 and lower contact 303 cooperate and guarantees air-tightness.
Top connection 303 is provided with a sealing ring 322, when inlet end on the removable device of breathing circuit and outlet side valve port dock with two spools 300 of the present utility model respectively, sealing ring 322 cooperates with lock spring 210, alignment pin 211, locking hole 214, this utility model and the removable device of breathing circuit closely are combined together, become one.Guaranteed that input is consistent with output concentration, the airway pressure of designing requirement simultaneously less than 12Kp, guarantees operate as normal greater than 8Kp, does not reveal.
The pressure control spring 307 of two spools 300 plays the effect of air-flow guiding, two pressure control spring 307 size differences, and the tension force of its formation varies in size.Pressure control spring 307 sizes at intake interface 191 places are littler than pressure control spring 307 sizes at interface 192 places of giving vent to anger, and deviation is at 1.5 ~ 2.3 millimeters.This purpose of design is can effectively control flow greater than 20L/min when making intake interface 191 by pressure control spring 307.The size constancy of the pressure control spring 307 in its air outlet adapter 192, pressure are not subjected to any restriction operate as normal, thereby have guaranteed the stable of output flow, export the stable of anesthetic concentration.
Ultimate principle of the present utility model is as follows:
1, under static work, just this utility model is not installed the removable device of breathing circuit.A stable source of the gas enters intake interface 191 through effusion meter control, and the interface 192 of giving vent to anger connects breathing circuit.This moment, stage clip 308, the pressure control spring 307 of two spools 300 were in original state, valve seat gas path 10 1 on the valve seat 100 communicates with the gas port 309 of two spools 300, make bypass open, under the effect of bleed pressure,, make gas flow to the interface 192 of giving vent to anger and entered breathing circuit and finish whole respiratory from valve seat gas path 10 1 with the upper valve core 304 of two spools 300 and the upper outlet of bottom spool 305 shutoff spools 300.The passage of gas is: gas enters the gas port 309 of gas port 309 through the right spool 300, valve seat gas path 10 1, left side spool 300 by intake interface 191, and interface 192 flows out by giving vent to anger.
2, under dynamic duty, just this utility model has been installed the removable device of breathing circuit.A stable source of the gas enters intake interface 191 through effusion meter control, be divided into two-way in this utility model air pressure inside this moment: one road gas is through valve seat gas path 10 1, valve seat gas path 10 1 300 mouthfuls of spools under the downward effect of the removable device outlet valve of breathing circuit push rod, with pressure control spring 307, the spiral shell type buttonhole of stage clip 308 cooperates the pulling force of 210 lock springs to drive down 1 shutoff of valve seat gas path 10 on spool mouth top with upper valve core 304 and bottom spool 305.Guaranteed anesthesia accurately, reliable.Other one road gas is to back down the removable device cavity of the breathing circuit portion that enters in the effect downwards of the removable device of breathing circuit outlet push rod, and the pulling force of the extension spring of this moment is greater than pressure control spring 307, the tension force that stage clip 308 makes progress.Guaranteed the complete input breathing circuit of anesthesia gas.
The downward pressure of the removable device of breathing circuit is greater than the tension force of pressure control spring 307, the pressure control spring 307 at interface 192 places of giving vent to anger this moment makes under the pressure of the top of the removable device of breathing circuit under the effect of bottom spool 305 at sealing ring, shutoff gas passway 101 and gas port 309, make the output concentration of the removable device of breathing circuit import breathing circuit fully.Guarantee anesthetic gases complete be transported to breathing circuit, simultaneously, also will seal the lie air-flow, the complete output of assurance anesthetic gases.
Advantage of the present utility model and beneficial effect:
1, adopt said structure after, effectively that anesthetic gases is complete input in the breathing circuit, prevented the leakage of gas.Use the pressure control spring 307 in the spool 300 to adjust stream pressure simultaneously, make that anaesthetic gas output concentration stabilize is reliable.
2, being connected of breathing circuit and anesthetic machine, adopt the removable device of breathing circuit to dock with the direct hard joint of adapter of the present utility model, convenient and swift.Eliminated when docking by flexible pipe, manually-operated firmly, the dynamics difference may cause the situation of gas leak.
