The attachmentes such as oxygen pipe.As shown in Figure 3-4, when using function is supplied oxygen, suction shaft 7 is closed, opens oxygen supply switch 6, at this time oxygen
Oxygen supply interface 2 can be reached by the oxygen supply access inside gas path module 100, oxygen supply interface 2 connects oxygen face mask or oxygen uptake
The attachmentes such as pipe supply patient's oxygen uptake.It is connected with adjusting pressuring knob 11 on this access and adjusts air pressure, the pressure in gas circuit can be with
It is read out on pressure gauge 12.
As Figure 7-9, negative pressure element 200, the air inlet 1 and the negative pressure element are provided in the gas outlet 3
200 form attraction gas circuit.The negative pressure element 200 includes the first negative pressure element 9 and the second negative pressure element 10, first negative pressure
The first gas passage 9-1 communicated and clamping chamber 9-2 are provided on element 9, the second negative pressure element 10 is fastened on the card
It connects in chamber 9-2, the second suction port 9-21, the second suction port 9-21 and described first is provided on the clamping chamber 9-2 and is inhaled
Draw mouth 8 to communicate.The second negative pressure element 10 is provided with second gas channel 10-1, the second gas channel 10-1 with it is described
The concentric setting of first gas passage 9-1.
As Figure 8-9, cone connection 9-3, institute are provided between the first gas passage 9-1 and clamping chamber 9-2
It states first gas passage 9-1 and is connected with clamping chamber 9-2 by the cone connection 9-3.The second gas channel 10-1's
Outlet end 10-11 is set in the cone connection 9-3.When the oxygen with certain flow rate is flowed from second gas channel 10-1
When to first gas passage 9-1, negative pressure will be generated near cone connection 9-3, and pass through the second suction port 9-21 and attract chamber 5
In gas flow gas outlet 3, chamber 5 again and attract interface 4 communicate, at this time attract interface 4 at can generate suction, as negative pressure
Source uses.
It is provided with input end 9-11 on the first gas passage 9-1, is provided with out on the second gas channel 10-1
Mouth end 10-11, the input end 9-11 is opposite with the outlet end 10-11, and the area of the input end 9-11 goes out greater than described in
The area of mouth end 10-11 guarantees the gas of outlet end 10-11 outflow completely into input end 9-11, guarantees to flow in gas and make
Under, the flowing of cone connection 9-3 peripheral region gas is driven, negative pressure is generated.
As Figure 7-8, fluted 13 are arranged on the first negative pressure element 9, there are two O-shaped for setting in the groove 13
Sealing ring 14, the second suction port 9-21 are set between two O-ring seals 14.O-ring seal 14 plays sealing and makees
With guarantee gas does not leak, and keeps constant pressure.
Attract gas circuit that sputum, hydrops, secretion, liquid, gas of patient's body etc., or operation etc. can be attracted to treat
Cleaning liquid, body fluid, blood for being generated in journey etc., in the present embodiment, to attract sputum.In the present embodiment, attract the connection storage of interface 4
The attachmentes such as liquid cup and sputum aspirator tube, the present apparatus only provides negative pressure source in use, and sputum is sucked out by sputum aspirator tube, suction
Sputum is stored in liquid storing cup, and the present apparatus is not direct to be contacted with the secretion being attracted, and is isolated by liquid storing cup.
Such as Fig. 5-6, when using attracting gas circuit suction sputum, suction shaft 7 is opened, closing oxygen supply switch 6, oxygen passes through gas circuit mould
Attraction access inside block reaches gas outlet 3, when oxygen passes through gas outlet 3, since air flowing is formed inside gas outlet 3
The air of negative pressure, chamber 5 flows to gas outlet 3 by the access inside gas path module 100, and chamber 5 is communicated with attraction interface 4 again,
Suction can be generated by attracting at interface 4 at this time, then sputum in patient body is drawn onto liquid storing cup by dedicated sputum aspirator tube.
Embodiment two
It is different with embodiment one, attracting gas, or attract the lesser sputum of density, hydrops, secretion, liquid
Body, etc., or operation etc. generate in therapeutic process cleaning liquid, have little time to connect attachment under body fluid, blood, or the burst state of emergency
When (for attracting sputum), sputum directly can be attracted by sputum aspirator tube, the sputum of suction is through straight by gas outlet 3 inside the present apparatus
Run in out.
When attraction, being attracted object can gradually be converged in cone connection 9-3 into input end 9-11, conveniently be attracted object
Discharge.The area of input end 9-11 is greater than the area of outlet end 10-11, when generating vacuum suction, is on the one hand convenient for being attracted
Object is discharged with the oxygen of certain flow rate；Another aspect input end 9-11 receives the air-flow from outlet end 10-11 comprehensively, prevents
Stop-band has the oxygen of certain flow rate to bump against from the outlet end 10-11 air-flow come out and cone connection 9-3, guarantees the flow velocity of oxygen
Do not weaken.
Second suction port 9-21 is limited between two O-ring seals 14, be will be attracted object and is limited in two O-ring seals
Between 14, ensuring to be attracted object during attraction on negative pressure element can all be sucked out as far as possible, avoid attraction in negative pressure
Large area is spread on element, makes to keep clear inside gas path module.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It can still modify to technical solution documented by previous embodiment, or be equal to part of technical characteristic
Replacement；And these are modified or replaceed, the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
