Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
Embodiment 1
As shown in accompanying drawing 1 and accompanying drawing 2, medical atomized administrator, it comprises a box body 1, tray interior is provided with a Venturi tube 2, and Venturi exit end stretches out box body and be provided with pipe joint 3 on this end, and the arrival end of Venturi tube is connected with the oxygen pump 4 in box body, a feed tube 6 is provided with at venturi throat 5, feed tube 6 is through with venturi 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 stream of oxygen pump 4 output is entered by the import of Venturi tube 2, when it is by venturi throat 5, its flow velocity increases, pressure reduces, pressure differential is produced between venturi throat 5 and feed tube 6, negative pressure is formed in feed tube 6, medicinal liquid in medicinal liquid cavity 7 is inhaled into venturi throat 5 inside and oxygen mix, when medicinal liquid and oxygen are by the expansion with Venturi tube internal diameter after venturi throat 5, its reduced velocity flow, pressure increases generation atomizing effect, medicinal liquid after this atomization is sent by Venturi exit.Atomized medicine introducing pipe (attached not shown) is connected with Venturi exit end by the pipe joint 3 of Venturi exit end, after atomization medicine enters atomized medicine introducing pipe, with the reduction of atomized medicine introducing pipe diameter, its flow velocity increases further, send into patient's medicine-feeding part by administration cover (attached not shown), supply while realizing medicine, oxygen.
Further, as shown in Figure 1, the pipeline that Venturi tube 2 entrance is connected with oxygen pump 4 is provided with air pressure regulator 9, feed tube 6 is provided with Controlling solenoid valve 10, air pressure regulator 9, Controlling solenoid 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.
After adopting above-mentioned setting, the opening degree of air pressure regulator 9 and Controlling solenoid valve 10 can be controlled by function button 12, with the amount controlling oxygen, medicinal liquid enters Venturi tube, meet the demand of patient's dosage.
Further, as shown in Figure 1, heating tube 13 and thermocouple 14 is provided with in medicinal liquid cavity 7, heating tube 13 and thermocouple 14 are electrically connected with the electric controller 11 in described box body, the fluid temperature in medicinal liquid cavity 7 is detected by thermocouple 14, the work of heating tube 13 is controlled by electric controller 11, by the medicine liquid heating in medicinal liquid cavity 7 to suitable temperature, medicinal liquid with suitable temperature effectively can reduce the stimulation to patient after atomization, reduce the sense of discomfort of patient, improve atomized medicine introducing effect further.
Embodiment 2
In the atomized medicine introducing device that embodiment 1 provides, although installed Controlling solenoid valve 10 on feed tube additional, but this Controlling solenoid valve 10 controls separately with air pressure regulator 9, reach the effect that medicinal liquid liquid inlet volume and air inflow match, need its coupling value of pre-stored in electric controller 11, during control, being outputed signal by electric controller 11 according to the coupling value stored is be opened into suitable output with air pressure regulator 9 respectively by Controlling solenoid valve 10, this rate-determining steps causes electric controller 11 to design complexity, and difficulty of programming increases, coupling value needs to have and good linearly just can reach accurate control.
For solving this problem, provide feed liquor control device that is a kind of and air inflow real-time matching in the present embodiment.
As shown in accompanying drawing 3, accompanying drawing 4, in the atomized medicine introducing device that the present embodiment provides, feed tube 6 is provided with arm 15, the external part of arm 15 is connected with venturi throat 5 by negative pressure straw 16, arm 15 inwall is provided with spring and supports platform 17, spring 18 end support is supported on platform 17 at spring, and spring 18 head end is connected with shutoff plug 19, and it is inner that shutoff plug 19 is plugged in feed tube 6.
The operation principle of this liquid inlet volume control device is: when atomizing administration device does not work, and 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 pumped when oxygen pump enters in Neiqiu after pipe, when air-flow is by Neiqiu Li Guan throat 5, place of throat produces pressure differential, and now in negative pressure straw 16, pressure reduces, 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 the opening degree adjusting air pressure regulator 9 controls oxygen inlet, the pressure at place of Li Guan throat 5, Neiqiu changes thereupon, also there is change in the pressure differential at shutoff plug 19 two ends, this pressure differential will adjust the amplitude of shrinking back of shutoff plug 19 automatically, thus the open amount controlling feed tube 6 reaches the object of adjustment liquid inlet volume.As can be seen here, when strengthening oxygen inlet, the pressure differential at shutoff plug 9 two ends strains greatly mutually, and shutoff plug amplitude of shrinking back strengthens, and liquid inlet volume strengthens, otherwise liquid inlet volume reduces, and liquid inlet volume adjusts automatically with the change 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.Such liquid gravity vertically downward can produce an outside decomposition thrust to shutoff plug, after negative pressure straw 16 internal pressure reduces, and the outside slip that shutoff plug 19 can be sensitiveer.
