Description
Technical field
This utility model relates to a kind of Anesthesia Department medical apparatus and instruments, specifically a kind of breathing circuit for anesthesia structure.
Background technology
Breathing circuit for anesthesia structure is widely used at present in the therapeutic process of anesthesia management, postoperative care and critically ill patient and respiratory failure, the correctness that its breathing circuit structure influence is breathed.
Publication number is that the Chinese patent of CN201492780U describes a kind of breathing circuit for anesthesia, and it adopts anaesthetic mask to connect Y type air tube through transit joint, then is connected to anesthesia respirator is realized by the suction tube of Y type air tube, exhale tube.Its weak point is, the positive pressure respiration that this breathing circuit can only be driven by anesthesia respirator, the pipeline malleation that patient is triggered and the oxygen content of breathing gas uncontrollable.
Summary of the invention
This utility model provides a kind of breathing circuit for anesthesia structure, and it can be driven by anesthetic machine, respirator and reservoir bag realize positive pressure respiration, and pressure in loop, oxygen content are controlled, safe and reliable.
The technical scheme that this utility model specifically adopts is:
A kind of breathing circuit for anesthesia structure, comprise the Y type air tube be made up of suction tube, exhale tube, Y type air tube joint portion connecting hose, the flexible pipe other end connects face shield, it is characterized in that, exhale tube forms the first loop by the first check valve, air inlet pipe, anesthesia gas flow tube, the second check valve and suction tube, and air inlet pipe is provided with CO2 absorber system, and anesthesia gas flow tube connects anesthetic machine; Air inlet pipe top is provided with selector switch, connect respirator and reservoir bag respectively by pipeline, reservoir bag is provided with pressure limiting valve, and respirator connects selector switch by breathing circuit, be provided with second servo loop between breathing circuit and respirator, second servo loop arranges malleation relief valve.
Further, be monitoring ventilation and control oxygen, carbon dioxide content, exhale tube arrange ventilation monitor, gas sampling mouth is set in Y type air tube joint portion.
Compared with prior art, the utility model has the advantages that:
1) can realize being driven by anesthetic machine, respirator and reservoir bag realizing positive pressure respiration, the intermittent breathing circulation triggered by patient can be realized again;
2) pressure in loop, oxygen content are controlled, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-malleation relief valve, 2-respirator, 3-first check valve, 4-ventilation monitor, 5-exhale tube, 6-gas sampling mouth, 7-flexible pipe, 8-suction tube, 9-second check valve, 10-selector switch, 11-anaesthetizes gas flow tube, 12-CO2 absorber system, 13-air inlet pipe, 14-reservoir bag, 15-pressure limiting valve, 16-breathing circuit.
Detailed description of the invention
As shown in Figure 1, a kind of breathing circuit for anesthesia structure, comprise the Y type air tube be made up of suction tube 8, exhale tube 5, Y type air tube joint portion connecting hose 7, flexible pipe 7 other end connects face shield (not identifying in figure), exhale tube 5 forms the first loop by the first check valve 3, air inlet pipe 13, anesthesia gas flow tube 11, second check valve 9 and suction tube 8, air inlet pipe 13 is provided with CO2 absorber system 12 for absorbing and carbon dioxide content in control loop, anesthesia gas flow tube 11 connects anesthetic machine (not identifying in figure), air inlet pipe 13 top is provided with selector switch 10, respirator 2 and reservoir bag 14 is connected respectively by pipeline, the medical oxygen of compression is had in reservoir bag 14, reservoir bag 14 is provided with pressure limiting valve 15, pressure limiting valve 15 is by regulating pressure, control oxygen intake, respirator 2 connects selector switch 10 by breathing circuit 16, second servo loop is provided with between breathing circuit 16 and respirator 2, second servo loop arranges malleation relief valve 1, for pressure in control loop, exhale tube 5 arranges ventilation monitor 4, in Y type air tube joint portion, gas sampling mouth 6 is set, this gas sampling mouth 6 connects gas-detecting device, the content of oxygen and carbon dioxide in monitoring circuit.
The process of this utility model positive airway pressure is: from the anesthesia anesthesia gas of gas flow tube 11, the air of respirator 2 or/and the oxygen of reservoir bag 14 enters loop, and mix with the expired gas of CO2 absorber system 12, form positive pressure gas and enter patient airway, after earth pressure release, patient is passive, and expired gas enters loop, if pressure is excessive, then discharge loop by malleation relief valve 1.
Claims (2)
