Description
Technical field
This utility model relates to a kind of anesthesia respirator, relates in particular to the gas circuit structure of anesthesia respirator, belongs to armarium manufacturing technology field.
Background technology
In the anesthesia respiration system, because patient expired gas carries remaining anesthetic gases, need the gas that patient end is breathed out be filtered, absorb filtering carbon dioxide wherein, patients repeats to suck then.Generally adopt the control system that has the bellows device to realize, as shown in Figure 1.During patient inhales; The leather bag 1 of bellows is after the quick oxygen supply of anesthetic machine is full of; Order about anesthetic gases through driving gas inlet 2 and flow to breather cheek valve 4 through tourie 3, live gas also flows to breather cheek valve 4 through live gas inlet 5 simultaneously, and gets into patient pulmonary through air entry 6.Gas is behind patient body's internal recycle, and patient begins to exhale, and this moment, the anesthetic machine driving gas stopped air feed; The systolic pressure of patient pulmonary makes the gas of having crossed at patient body's internal recycle flow to expiratory one-way valve 8 through exhalation vents 7; And open expiratory one-way valve 8 and flow to tourie 3 and driving gas inlet 2, anesthetic machine driving gas this moment air feed once more is because expiratory one-way valve only allows gas unidirectional to flow; So driving gas compressing breath flows to the inlet of tourie 3 and gets into tourie 3; After the filtration of breath through sodica calx in the tourie 3, filtering carbon dioxide wherein gets into patient inhales mouth 6 again.This moment, a breath cycle was accomplished.In above-mentioned gas circuit structure, because the driving gas outlet that the interior breath of lung flows to bellows can form certain pressure, for different patient; It is different that bellows receive intrapulmonic pressure power; And pressure changes with patient's intrapulmonic pressure power, make bellows urceolus institute indexing can't the normal reaction lung in the gas supply situation, particularly when being applied to neonatal patient; Its influence is very big; And because the overflow valve 9 in the bellows exists a small malleation or small negative pressure, this pressure seriously influences neonatal ventilation, can cause the problem of the excessive or hypoventilation of neonate ventilation.Simultaneously,, cause in the pressure control procedure, can not well reaching pressure platform, be easy to occur causing pressure platform too high, be difficult to reach the setting pressure requirement because leather bag elasticity changes because the pliability of the inner leather bag of bellows is difficult to control.
The utility model content
The purpose of this utility model is to provide a kind of gas circuit structure of anesthesia respirator, can overcome the above-mentioned defective of existing anesthesia respiration system, can guarantee the safety requirements that reaches setting of the intravital anesthetic gases pressure of input patient, gas gross.
The technical scheme of this utility model is following:
A kind of gas circuit structure of anesthesia respirator; Comprise driving gas inlet, live gas inlet, air entry, breather cheek valve, exhalation vents, expiratory one-way valve, tourie in the said gas circuit; It is characterized in that: also comprise a cavity volume in the said gas circuit; Said cavity volume inside is provided with zigzag gas piping, and said driving gas inlet connects an end of the tortuous gas piping of cavity volume, and the gas outlet end of said expiratory one-way valve connects the other end of the tortuous gas piping of cavity volume; The air inlet end of said expiratory one-way valve connects said exhalation vents; The middle part of the tortuous gas piping of said cavity volume; Be provided with the air inlet end that a branch line connects said tourie, the gas outlet end of said tourie, and said live gas inlet; The air inlet end that connects said breather cheek valve, the gas outlet end of said breather cheek valve connects said air entry.
This utility model is applied to can anesthetic gases and live gas be sent into patient pulmonary accurately in guiding of clinical anesthesia initial stage and the surgery anesthesia.This utility model is in whole breath cycle process; Not only can allow breath to repeat to suck and guarantee the unipolarity of airflow direction; Have the live gas compensation to make the anaesthetic relative concentration of suction more stable during making ventilation, and owing between driving gas inlet and expiratory one-way valve, be provided with cavity volume, the space of cavity volume is enough big always; And air flue is even, resistance is very little right; The pressure of breath and driving gas plays cushioning effect, guarantees the safety of the intravital anesthetic gases pressure of input patient, gas gross, and the gas that can make the patient end exhalation simultaneously is not when leaking; Just driven the entering tourie once more, thereby realize repeating to suck by driving gas.

The specific embodiment
The anesthesia respiration system principle of this utility model is as shown in Figure 2; Except that comprising the leather bag identical 1, driving gas inlet 2, live gas inlet 5, breather cheek valve 4, air entry 6, expiratory one-way valve 8, exhalation vents 7, tourie 3, also comprise a cavity volume 10 with prior art.Said leather bag 1 connects an end of said cavity volume 10 through driving gas inlet 2 through gas circuit, and the other end of said cavity volume 10 connects the gas outlet end of said expiratory one-way valve 8 through gas circuit, and the air inlet end of said expiratory one-way valve 8 connects said exhalation vents 7; Gas circuit between said cavity volume 10 and the expiratory one-way valve 8 connects the air inlet of said tourie 3 again, and the gas outlet of said tourie 3, and live gas inlet 5 connect said air entry 6 through gas circuit through said breather cheek valve 4.In addition, in the anesthesia respiration system, also be provided with the APL equilibrated valve 11 identical, flow measurement device 12, PEEP valve 13, oxygen sensor 14 etc. with prior art.
Fig. 3 is the gas circuit structure sketch map of this utility model, display driver gas access 2, live gas inlet 5, breather cheek valve 4, air entry 6, expiratory one-way valve 8, exhalation vents 7, cavity volume 10, and the arrow among the figure shows gas flow.Said cavity volume 10 inside are provided with tortuous gas circuit, and this complications gas circuit one end connects driving gas inlet 2, and the other end connects expiratory one-way valve 8; The middle part of said tortuous gas circuit is provided with branch's gas circuit 101 and connects tourie.
The work process of this utility model is following: during patient inhales, the live gas that is got into by the live gas inlet gets into patient pulmonary through breather cheek valve; Patient exhales is passed through the pipeline flow-direction expiratory one-way valve at the gas that patient body's internal recycle has been crossed then, and opens expiratory one-way valve entering cavity volume, and cavity volume inside is provided with tortuous gas circuit; The space is enough big, holds breath fully, at this moment; Exhale and finish, expiratory one-way valve is closed, the leather bag compression; Driving gas is started working, and gets into cavity volume by the driving gas inlet, orders about the breath reverse flow that gets into cavity volume; Because expiratory one-way valve is closed, the gas in the cavity volume can only get into tourie, and the carbon dioxide in tourie in the gas is absorbed; Remaining gas flows out tourie by the tourie outlet under the pressure of driving gas, together get into patient pulmonary through breather cheek valve with live gas, accomplishes a circulation.Owing to the effect of cavity volume, the gas that can make the patient end exhalation is just driven the entering tourie by driving gas once more when not leaking in the said process, thereby realizes repeating to suck.And the space of cavity volume is enough big, and air flue is even, resistance is very little right, and the pressure of breath and driving gas plays cushioning effect, guarantees the safety of the intravital anesthetic gases pressure of input patient, gas gross.
