The technical scheme in the invention for solving the technical problem is: a kind of nasal cavity dosing device, comprise storing medicine bottle, medicine absorbing tube, medicine-feeding actuating unit and drug discharging tube, described storing medicine bottle upper end is provided with opening, described medicine absorbing tube stretches to storing medicine bottle bottom by opening, and the top of described medicine absorbing tube is connected at opening part with storing medicine bottle; It is characterized in that: also comprise and inhale prescription to lobe, drug one-way valve and quantitative mechanism; Described medicine-feeding actuating unit comprises outer shell and piston rod, and a side of described outer shell is provided with piston hole, and the end of described piston rod stretches to the inside of outer shell through piston hole, and the end diameter of piston rod is identical with the internal diameter of outer shell; A side that differs from piston hole on described outer shell is provided with two connecting holes, and the upper end of described medicine absorbing tube is connected with a connecting hole of outer shell by inhaling medicine one-way valve, and the tail end of described drug discharging tube is connected with another connecting hole of outer shell by drug one-way valve; The head end of described drug discharging tube is provided with medicine nozzle; Described quantitative mechanism comprises sliding bar, fixed bar and buckle; The upper end of described sliding bar is provided with slide block, and the lower surface of described fixed bar is provided with the slideway matching with slide block, and slide block is arranged in slideway; The upper surface of described fixed bar is provided with the scale of drug dose; Described fixed bar is provided with buckle; Described fixed bar one end is fixedly connected with drug discharging tube, and one end, below of fixed bar is provided with a spring, and one end of described spring is fixedly connected with sliding bar, and the other end is fixedly connected with drug discharging tube; The head end of described piston rod is fixedly connected with sliding bar.
Above-mentioned medicine absorbing tube with storing medicine bottle for being flexibly connected.
The end of above-mentioned piston rod is round pie.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, simple in structure, easy to use, can accurate quantitative analysis complete administration, make effect of drugs stable, improved curative effect.
2, pass through medicine nozzle to patient's nasal-cavity administration, comfort level is high.
3, cost is low, can be used in other local dosed administrations, is widely used, and is convenient to promote.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, this utility model comprises storing medicine bottle 1, medicine absorbing tube 2, inhales medicine one-way valve 3, drug one-way valve 4, quantitative mechanism, medicine-feeding actuating unit and drug discharging tube 14.
Described storing medicine bottle 1 upper end is provided with opening, described medicine absorbing tube 2 stretches to storing medicine bottle 1 bottom by opening, and the top of medicine absorbing tube 2 is flexibly connected at opening part with storing medicine bottle 1, while needing to add medicinal liquid in storing medicine bottle 1, medicine absorbing tube 2 can be taken off, convenient to injection in storing medicine bottle 1.
Described medicine-feeding actuating unit comprises outer shell 5 and piston rod 6, and a side of described outer shell 5 is provided with piston hole, and the end of described piston rod 6 stretches to the inside of outer shell 5 through piston hole, the end round pie of piston rod 6, and its diameter is identical with the internal diameter of outer shell 5.
A side that differs from piston hole on described outer shell 5 is provided with two connecting holes.The upper end of described medicine absorbing tube 2 is connected with a connecting hole of outer shell 5 by inhaling medicine one-way valve 3, makes medicinal liquid flow into outer shell 5 from medicine absorbing tube 2, and can not flow backwards by inhaling medicine one-way valve 3.The tail end of described drug discharging tube 14 is connected with another connecting hole of outer shell 5 by drug one-way valve 4, by drug one-way valve 4, makes medicinal liquid flow into drug discharging tube 14 from outer shell 5, can not flow backwards.The head end of described drug discharging tube 14 is provided with medicine nozzle 12, and by 12 pairs of patient's nasal-cavity administrations of medicine nozzle, comfort level is high.
