Description

The synchronous jet ventilator of two-phase

This utility model relates to a kind of lifesaving appliance, particularly a kind of synchronous jet ventilator of the two-phase of using when giving emergency treatment to a patient that is applicable to.

At present, the generally air supply system formed by housing, with the empty oxygen mixer of the joining high frequency of housing, carrier pipe, relief valve, breathing head of the high frequency respirator of Shi Yonging, the electric-control system of forming by on and off switch, transformator, circuit board, pick off, electromagnetic valve and lead in addition.It has easy to use, and is safe and reliable, and advantage applied widely can be used for clear-headed patient and pulmonary belb, bronchopleural fistula, pneumothorax and bronchoscopy etc., to improving partial pressure of oxygen and improving the dyspnea aspect good effect is arranged.But it is because be to use the oxygen supply of single high frequency machinery, and frequency is fast, can't adjust, can't be initiatively when clear-headed patient uses and respirator cooperate breathing synchronously, the II type is exhaled the PaCO that declines ₂The reduction effect not obvious, range of application is little.

The purpose of this utility model is a kind of advantage that had both had high frequency respirator of design, can enlarge range of application again, improves the synchronous jet ventilator of two-phase of rescue effect.

Task of the present utility model is finished as follows, it includes housing, the housing internal fixation has empty oxygen mixer of high frequency and relief valve thereof, the empty oxygen mixer of high frequency communicates by the outer breathing head of appendix and housing, on and off switch is installed on the housing, circuit board in transformator and the shell links, it is characterized in that: the appendix by empty oxygen mixer is provided with a frequency modulator, the appendix of frequency modulator back is provided with a flow transducer and an electromagnetic valve, there is lead to connect on flow transducer and the electromagnetic valve respectively with circuit board, on housing, be connected with the Synchronization Control key respectively by lead again on the circuit board, the classification options button, the expiration key, air-breathing key, in housing, be connected with pressure transducer, outside housing, be connected with synchronous breath controller.

When machine and patient respiration were synchronous, pressure transducer and breath controller is harmonious synchronously can make respirator meet the patient respiration beat fully, reaches the stage that patient comfort is breathed; When clear-headed patient uses, because of respirator is being exhaled and can sent different sound when air-breathing, can be initiatively along with the sound of respirator or seeing traffic lights and its are synchronous and cooperate, the beat active that can also follow the time with have synchronous with respirator preparatively.This ventilator-structure is simple, and both it had the effect of high frequency jet ventilator, and the effect of synchronized pulmotor is arranged again, has enlarged range of application, adapts to different respiratory forms, has improved rescue and therapeutic effect.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is a structural representation of the present utility model.

This respirator includes housing 9, housing 9 internal fixation have empty oxygen mixer 4 of high frequency and relief valve 5 thereof, the empty oxygen mixer 4 of high frequency communicates by appendix and housing 9 breathing outward 3, on and off switch 1 is installed on the housing 9, circuit board 16 in transformator 2 and the shell links, appendix by empty oxygen mixer 4 is provided with a frequency modulator 6, the appendix of frequency modulator 6 back is provided with a flow transducer 7 and an electromagnetic valve 8, there is lead to connect on flow transducer 7 and the electromagnetic valve 8 respectively with circuit board 16, on housing, be connected with Synchronization Control key 10 respectively by lead again on the circuit board 16, classification options button 12, expiration key 14, air-breathing key 15, in housing, be connected with pressure transducer 11, outside housing, be connected with synchronous breath controller 13.When using this machine, earlier synchronous breath controller 13 is placed both sides, the most obvious place of patient's chest respiratory movement suitably fixing with backguy, energized switch 1 and transformator 2, and the connection source of the gas, respirator is just started working, and air is entered in the sky oxygen mixer 4 by source of the gas, its pressure size is by relief valve 5 controls, be provided with a frequency modulator 6 near the appendix of empty oxygen gas mixture, in order to gaseous mixture being formed the high frequency jet state, between per minute 100-400 time.Undertaken the opening or closing of gas controlled above program and finished by air-breathing key 15, expiration key 16, classification options button 12 and synchronous key 10 by circuit board 16 and relay controlled pressure pick off 11 again.When respirator and patient respiration are synchronous, on the one hand can triggering synchronous when the perception patient inhales negative pressure by jet breathing 3 and pressure transducer 11; In addition by synchronous breath controller 13 triggering synchronous when the perception patient's chest is moved.In the time of two kinds of pick offs and with in order that learn from other's strong points to offset one's weaknesses, make it perfectly safe, and can when the true no spontaneous breathing of patient, generally rise automatically and send out control breathing again in the 10 seconds secondary backs that cease breathing, if patient has had autonomous respiration again, this respirator can be breathed synchronously with patient again.When patient was will be with respirator synchronous, clear-headed in this way patient can hear that air-breathing sound is synchronous with it on the one hand; Can see that again air-breathing green light is synchronous with it; Can also be initiatively and have synchronous with respirator preparatively according to the beat of time.The operation principle of Here it is the synchronous jet ventilator of so-called two-phase.It when patient inhales, have a jet-stream wind with the frequency of per minute 100-400 time to gas-duct jetting, when patient exhales, air-flow just interrupts, and like this, has just brought into play the advantage of high frequency respirator, and has overcome its shortcoming, makes it to exhale for the II type patient's that declines PaCO ₂Reduction definite significantly effect has been arranged, enlarged range of application, derived some new respiratory forms.
