Description
Technical field
The present invention relates to a kind of anesthesia respirator, belong to armarium manufacturing technology field.
Background technology
In anesthesia respiratory system, because patient's Exhaled gasesS carries remaining anesthetic gases, need to filter the patient end Exhaled gasesS, absorb filtering carbon dioxide wherein, then repeat to suck for patient.Generally adopt the control system with 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 by driving gas entrance 2 and flow to breather cheek valve 4 through tourie 3, live gas also flows to breather cheek valve 4 through live gas entrance 5 simultaneously, and enters patient pulmonary through air entry 6.Gas is behind patient body's internal recycle, patient begins to exhale, this moment, the anesthetic machine driving gas stopped air feed, the systolic pressure of patient pulmonary is so that the gas of having crossed at patient body's internal recycle flows 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 entrance 2, anesthetic machine driving gas this moment air feed again, because expiratory one-way valve only allows gas unidirectional to flow, so driving gas compressing breath flows to the entrance of tourie 3 and enters tourie 3, after the filtration of breath through tourie 3 interior sodica calx, filtering carbon dioxide wherein enters patient inhales mouth 6 again.This moment, a breath cycle was finished.Because the driving gas outlet that the interior breath of lung flows to bellows can form certain pressure, for different patients, it is different that bellows are subject to intrapulmonic pressure power, and pressure changes with the Patients with Lung internal pressure, so that bellows urceolus institute indexing can't the normal reaction lung in the gas supply situation, particularly when being applied to neonatal patient, its impact is very large, 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, because the pliability of the inner leather bag of bellows is difficult to control, cause in the pressure control procedure, can not well reaching pressure platform, be easy to occur because the leather bag Flexible change causes pressure platform too high, be difficult to reach the setting pressure requirement.
Summary of the invention
The object of the present invention is to provide a kind of anesthesia respiratory system, can overcome the defects of existing anesthesia respiratory system, can guarantee the anesthetic gases pressure in the input patient body, the safety requirements that reaches setting of gas gross.
Technical scheme of the present invention is as follows:
A kind of anesthesia respiratory system with the fixed volume chamber, mainly comprise leather bag, driving gas entrance, live gas entrance, breather cheek valve, air entry, expiratory one-way valve, exhalation vents, tourie, it is characterized in that: described anesthesia respiratory system also comprises a cavity volume, described leather bag connects an end of described cavity volume by gas circuit through the driving gas entrance, the other end of described cavity volume connects the gas outlet end of described expiratory one-way valve by gas circuit, and the air inlet end of described expiratory one-way valve connects described exhalation vents; Gas circuit between described cavity volume and the expiratory one-way valve connects again the air inlet of described tourie, and the gas outlet of described tourie, and live gas entrance connect described air entry by gas circuit through described breather cheek valve.
Described cavity volume inside is provided with tortuous gas circuit, and this complications gas circuit one end connects the driving gas entrance, and the other end connects expiratory one-way valve; The middle part of described tortuous gas circuit is provided with a branch air path and connects described tourie.
The present invention is applied to anesthetic gases and live gas to be sent into patient pulmonary accurately in the guiding of clinical anesthesia initial stage and the surgery anesthesia.The present invention is in whole breath cycle process, not only can allow breath to repeat to suck and guarantee the unipolarity of airflow direction, there is the live gas compensation to make the anaesthetic relative concentration of suction more stable during making ventilation always, and owing between driving gas entrance and expiratory one-way valve, be provided with cavity volume, the space of cavity volume is enough large, and air flue is even, resistance is very little right, the pressure of breath and driving gas plays cushioning effect, guarantee the anesthetic gases pressure in the input patient body, the safety of gas gross, simultaneously can make the patient end Exhaled gasesS when not leaking, again drive with regard to driven gas and to enter tourie, thereby realize repeating to suck.

The specific embodiment
Anesthesia respiratory system principle of the present invention as shown in Figure 2, except comprising leather bag same as the prior art 1, driving gas entrance 2, live gas entrance 5, breather cheek valve 4, air entry 6, expiratory one-way valve 8, exhalation vents 7, tourie 3, also comprise a cavity volume 10.Described leather bag 1 connects an end of described cavity volume 10 through driving gas entrance 2 by gas circuit, and the other end of described cavity volume 10 connects the gas outlet end of described expiratory one-way valve 8 by gas circuit, and the air inlet end of described expiratory one-way valve 8 connects described exhalation vents 7; Gas circuit between described cavity volume 10 and the expiratory one-way valve 8 connects again the air inlet of described tourie 3, and the gas outlet of described tourie 3, and live gas entrance 5 connect described air entry 6 by gas circuit through described breather cheek valve 4.In addition, in the anesthesia respiratory system, also be provided with APL equilibrated valve 11 same as the prior art, flow measurement device 12, PEEP valve 13, oxygen sensor 14 etc.
Fig. 3 is gas circuit structure sketch map of the present invention, display driver gas access 2, live gas entrance 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.Described cavity volume 10 inside are provided with tortuous gas circuit, and this complications gas circuit one end connects driving gas entrance 2, and the other end connects expiratory one-way valve 8; The middle part of described tortuous gas circuit is provided with a branch air path 101 and connects tourie.
Work process of the present invention is as follows: during patient inhales, the live gas that is entered by the live gas entrance enters patient pulmonary through breather cheek valve; Then patient exhales, the gas process pipeline flow-direction expiratory one-way valve of having crossed at patient body's internal recycle, and open expiratory one-way valve and enter cavity volume, cavity volume inside is provided with tortuous gas circuit, the space is enough large, hold breath fully, at this moment, exhale and finish, expiratory one-way valve is closed, the leather bag compression, driving gas is started working, and enters cavity volume by the driving gas entrance, orders about the breath reverse flow that enters cavity volume, because expiratory one-way valve is closed, gas in the cavity volume can only enter tourie, and the carbon dioxide in tourie in the gas is absorbed, and remaining gas flows out tourie by the tourie outlet under the pressure of driving gas, together enter patient pulmonary through breather cheek valve with live gas, finish a circulation.Because the effect of cavity volume can make the patient end Exhaled gasesS when not leaking, again drive with regard to driven gas and enter tourie in the said process, thereby realize repeating to suck.And the space of cavity volume is enough large, and air flue is even, resistance is very little right, and the pressure of breath and driving gas plays cushioning effect, guarantees the anesthetic gases pressure in the input patient body, the safety of gas gross.
