The structural representation that accompanying drawing 3 is second embodiment of the invention.
Accompanying drawing 4 is the enlarged diagram at I place in accompanying drawing 3.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in accompanying drawing 1 and accompanying drawing 2, medical atomized administrator, it comprises a box body 1, box body inside is provided with a Venturi tube 2, and the Venturi tube port of export stretches out box body and on this end, is provided with pipe joint 3, and the arrival end of Venturi tube is connected with the oxygen pump 4 in box body, in Venturi tube throat 5, be provided with a feed tube 6, feed tube 6 connects with Venturi tube throat 5, and the other end of feed tube 6 is connected with medicinal liquid cavity 7, and medicinal liquid cavity 7 is opened on box body top and is provided with sap cavity lid 8.
The operation principle of this medical atomized administrator is: after the Oxygen Flow of oxygen pump 4 output is entered by the import of Venturi tube 2, when it passes through Venturi tube throat 5, its flow velocity increases, pressure reduces, between Venturi tube throat 5 and feed tube 6, produce pressure differential, the interior formation negative pressure of feed tube 6, medicinal liquid in medicinal liquid cavity 7 is inhaled into Venturi tube throat 5 inside and oxygen mix, when medicinal liquid and oxygen by after Venturi tube throat 5 with the expansion of Venturi tube internal diameter, its flow velocity slows down, pressure increases generation atomizing effect, medicinal liquid after this atomization is exported and is sent by Venturi tube.Atomized medicine introducing pipe (attached not shown) is connected with the Venturi tube port of export by the pipe joint 3 of the Venturi tube port of export, when atomization medicine enters after atomized medicine introducing pipe, with reducing of atomized medicine introducing pipe diameter, its flow velocity further increases, by administration cover (attached not shown), send into patient's medicine-feeding part, when realizing medicine, oxygen, supply with.
Further, as shown in Figure 1, on the pipeline being connected with oxygen pump 4 at Venturi tube 2 entrances, be provided with air pressure regulator 9, be provided with and control electromagnetic valve 10 on feed tube 6, air pressure regulator 9, control electromagnetic valve 10 and oxygen pump 4 are connected with the appliance controller 11 in box body.As shown in Figure 2, appliance controller 11 is provided with function button 12 on the surface of box body 1.
Adopt after above-mentioned setting, can control air pressure regulators 9 and control the opening degree of electromagnetic valve 10 by function button 12, to control oxygen, medicinal liquid, enter the amount of Venturi tube, meet the demand of patient's dosage.
Further, as shown in Figure 1, in medicinal liquid cavity 7, be provided with heating tube 13 and thermocouple 14, heating tube 13 and thermocouple 14 are electrically connected to the electric controller 11 in described box body, the fluid temperature detecting in medicinal liquid cavity 7 by thermocouple 14, by electric controller 11, controlled the work of heating tube 13, by the medicine liquid heating in medicinal liquid cavity 7 to suitable temperature, medicinal liquid with suitable temperature can effectively reduce the stimulation to patient after atomization, the sense of discomfort that reduces patient, further improves atomized medicine introducing effect.
Embodiment 2
In the atomized medicine introducing device providing at embodiment 1, although installed control electromagnetic valve 10 additional on feed tube, but this control electromagnetic valve 10 is to control separately with air pressure regulator 9, reach the effect that medicinal liquid feed liquor amount and air inflow match, need to be in electric controller 11 its coupling value of pre-stored, during control, according to the coupling value of storage, by electric controller 11 output signals, by control electromagnetic valve 10, be to be respectively opened into suitable output with air pressure regulator 9, this control step causes electric controller 11 designs complicated, and programming difficulty increases, coupling value need to have good linearity and just can reach accurate control.
For addressing this problem, provide in the present embodiment a kind of and feed liquor control device air inflow real-time matching.
As shown in accompanying drawing 3, accompanying drawing 4, in the atomized medicine introducing device providing at the present embodiment, on feed tube 6, be provided with arm 15, the external part of arm 15 connects by negative pressure straw 16Yu Venturi tube throat 5, on arm 15 inwalls, be provided with spring and support platform 17, spring 18 end support are supported on platform 17 at spring, and spring 18 head ends are connected with shutoff plug 19, and shutoff plug 19 is plugged in feed tube 6 inside.
The operation principle of this feed liquor amount control device is: when atomizing administration device is not worked, shutoff plug 19 is by feed tube shutoff under the effect of spring 18, and the medicinal liquid in medicinal liquid cavity can not be dirty.During work, the oxygen pumping when oxygen pump enters in Neiqiu after pipe, and air-flow is during by Neiqiu Li Guan throat 5, throat place produces pressure differential, and now negative pressure straw 16 internal pressures reduce, and shutoff plug 19 is shunk back automatically backward, feed tube 6 is opened, and medicinal liquid is inhaled in Neiqiu Li Guan throat 5.When adjusting the opening degree control oxygen inlet of air pressure regulator 9, the pressure at Li Guan throat 5 places, Neiqiu changes thereupon, changing also appears in the pressure differential at shutoff plug 19 two ends, this pressure differential will be adjusted the amplitude of shrinking back of shutoff plug 19 automatically, thereby the open amount of having controlled feed tube 6 reaches the object of adjusting feed liquor amount.As can be seen here, while strengthening oxygen inlet, the pressure differential phase strain at shutoff plug 9 two ends is large, and the shutoff plug amplitude of shrinking back strengthens, and feed liquor amount strengthens, otherwise feed liquor amount reduces, and feed liquor amount is adjusted automatically with the variation of oxygen air inflow.
Further, for making the activity of shutoff plug sensitiveer, as shown in Figure 4, the arm 15 on feed tube is obliquely installed with feed tube 6, the height of arm external part is lower than the height of arm and feed tube link, and the shutoff plug 19 in arm tilts to be plugged in feed tube inside.Liquid gravity vertically downward can produce an outside decomposition thrust to shutoff plug like this, after negative pressure straw 16 internal pressures reduce, and the outside slip that shutoff plug 19 can be sensitiveer.
