A nitric oxide high-frequency jet ventilation therapeutic apparatus, characterized in that the inlets of O2 , NO and NO2 are respectively connected to the inlet ports of three mass flow controllers 1, wherein the outlet port of the mass flow controller 1 controlling O2 It is connected to the inlet of the ventilator 4, the outlet of the ventilator 4 is connected to the main air circuit of the main machine, and the outlet port of the mass flow controller 1 for controlling O2 and NO is also connected to the main air circuit of the main machine, and O 2 , N 2 , NO or O 2. The N 2 mixed gas communicates with the NO sensor 2 and the NO 2 sensor 3 respectively, and is led out from the treatment gas outlet 10.
Description
This utility model relates to a kind of mode with high-frequency impulse with O
2Or the NO mist sprays into receptor's respiratory tract, reaches the nitric oxide high frequency jet ventilation therapeutic instrument of multiple disease such as treatment pulmonary disease.
At present, domestic only have a simple type NO respirator, and this instrument can be with the O of variable concentrations
2Or the NO mist sends into patient's respiratory tract, and pulmonary edema has been played excellent curative.But this instrument also exists some shortcoming and defect: 1, can not change the pulse frequency that sucks gas, thereby can not make the air-flow that enters in the air flue keep continuing uninterruptedly, to alveolar atrophic type pulmonary edema unsatisfactory curative effect; 2, be about to O by mass flowmenter in the initial part of pipeline
2Mix earlier with NO, cause NO
2More formation earlier can exert an adverse impact to body in pipeline; 3, can only show O on the fluorescent screen
2Or the concentration of NO, and can not show NO
2Concentration, to sucking the NO in the gas
2Concentration can't dynamic observe.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, and a kind of nitric oxide high frequency jet ventilation therapeutic instrument is provided, can be with O
2Or the NO mist sprays into receptor's respiratory tract in the mode of high-frequency impulse, and it is uninterrupted that gas in the respiratory tract is continued, the recovery of the alveolar that helps withering.Not only can show O on the instrument fluorescent screen
2With the concentration of NO, show NO but also can monitor
2Concentration.
The purpose of this utility model can reach by following measure:
A kind of nitric oxide high frequency jet ventilation therapeutic instrument is characterized in that O
2, NO and NO
2Import links to each other with the entrance point of three mass flow controllers 1 respectively, wherein controls O
2The port of export of mass flow controller 1 link to each other with respirator 4 imports, the outlet of respirator 4 links to each other with the total gas circuit of main frame, control O
2Also link to each other O with the port of export of the mass flow controller 1 of NO with the total gas circuit of main frame
2, N
2, NO or O
2, N
2Mist respectively with NO pick off 2 and NO
2Pick off 3 communicates, and draws from treatment gas outlet 10.
Advantage of the present utility model:
Since adopt such scheme, can be with the O of variable concentrations
2Or NO sprays into receptor's respiratory tract in the mode of high-frequency impulse; Accurately demonstrate O on the fluorescent screen simultaneously
2, NO and NO
2Concentration, remedied domestic can not the monitoring and shown NO with quasi-instrument
2The shortcoming of concentration has guaranteed that NO sucks the security reliability of treatment.
Fig. 1 is this utility model process of gas path figure.
Fig. 2 is this utility model structural representation.
Below in conjunction with accompanying drawing this utility model is further described:
In Fig. 1 and Fig. 2, regulated power supply 11 make instrument in the running supply voltage be in 220V ± 10%.Before start is prepared, with respirator 4, O
2 Steel cylinder gas 6, N
2 Steel cylinder gas 7 and NO steel cylinder gas 8 are connected with main frame.Open air valve and regulate air relief valve 5, gas outlet pressure is remained on about 3 kilograms.Connect voltage of voltage regulation 11, open the on and off switch on the face version, make instrument enter the self check state, and beginning preheating countdown.After preheating is finished, O
2O in the steel cylinder gas 6
2Through air relief valve 5 decompressions, from O
2Import 12 enters respirator 4 from respirator air inlet 15 after entering the mass flow controller 1 of main frame.After changing its pulse frequency, again in the mode of high-frequency impulse with O
2Send main frame back to through respirator gas outlet 16.N
2N in the steel cylinder gas 7
2With NO in the NO steel cylinder gas 8 after air relief valve 5 decompressions, from N
2Import 13 and NO import 14 enter main frame through mass flow controller 1, with the high frequency O that enters from respirator gas outlet 16
2At main gas or N
2, O
2, three kinds of mists of NO, by three-way valve 17, through NO pick off 2 and NO
2Pick off 3 detects the back sprays into the receptor from treatment gas outlet 10 modes with high-frequency impulse respiratory tract.
This utility model is at the end of main frame gas circuit, design and installation NO pick off 2 and NO
2Pick off 3, but NO and NO in the duplicate detection line-blending gas
2Concentration, play the purpose of double monitoring.
Three kinds of quality flow controllers 1 of this utility model design are controlled N respectively
2, O
2With the flow of NO three road gases, and by single-chip microcomputer calculating and demonstration O
2And NO
2Concentration.Electrochemical sensor NO and the NO in the repeated measure line-blending gas once more simultaneously
2Concentration reaches the effect of double monitoring, guarantees that instrument treatment is safe and reliable.
