For solving the problems of the technologies described above, the injection nasal sprayer provided, comprise the cannon spray head that can inject medicinal liquid, its construction features is: the inner chamber front portion of cannon spray head is equipped with atomization and is formed pad, the middle part that atomization forms pad is provided with liquid pass hole, be provided with to be atomized between the front portion of atomization formation pad and the front wall inner surface of cannon spray head and form chamber, spray film spray orifice is provided with in the middle of the antetheca of described cannon spray head, the front portion of described cannon spray head is connected with the shower nozzle that inner chamber is communicated with spray film spray orifice, shower nozzle is column and its front end face is hemispherical, the front end face of shower nozzle and sidewall are evenly equipped with multiple spray holes, the rear portion of described cannon spray head is connected with can to the medicinal liquid thrust unit of cannon spray head inner chamber herb liquid extruding.
Medicinal liquid thrust unit comprises the promotion cylinder being connected to cannon spray head rear portion, promote to slidably connect catch bar in cylinder, catch bar is connected with and stretches into cannon spray head inner chamber and can along the piston of wall slip in cannon spray head, catch bar is provided with land, between land and the inwall rear portion promoting cylinder, top spring is housed, the outside promoting cylinder is hinged with pull lever, between pull lever and the rear portion of catch bar, connecting rod is housed.
The liquid injection pipe with its inner space is equipped with at the sidewall rear portion of cannon spray head, the outer wall of cannon spray head is also equipped with the fluid injection outer housing of spiral-lock in liquid injection pipe outside.
Shower nozzle is connected with cover and is contained in shower nozzle outer housing outside shower nozzle.
After adopting said structure, injection of medicine in cannon spray head, by medicinal liquid thrust unit, the medicinal liquid in cannon spray head is extruded, medicinal liquid forms chamber through liquid pass hole and atomization and is formed vaporific, namely make use of the action principle of aerosol apparatus, make liquid quick break, liquid is through multiple spray holes ejections of shower nozzle, the shower nozzle of column can go deep in the nostril of patient, because the front end of shower nozzle and sidewall are all provided with spray holes, thus the medicinal liquid entered in patient's nasal cavity is very even, and it is different according to the lesions position of patient, the insertion depth of the shower nozzle of column can be controlled, thus medicinal liquid is gone directly focus, reach best therapeutic effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described:
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
As shown in Figure 1, injection nasal sprayer provided by the utility model comprises the cannon spray head 1 that can inject medicinal liquid, the inner chamber front portion of cannon spray head 1 is equipped with atomization and is formed pad 2, the middle part that atomization forms pad 2 is provided with liquid pass hole 21, the diameter of liquid pass hole 21 is less than the diameter of cannon spray head 1, be provided with to be atomized between the front portion of atomization formation pad 2 and the front wall inner surface of cannon spray head 1 and form chamber 22, this atomization forms chamber 22 and the structure in the present embodiment can be adopted to be formed, namely the leading section of atomization formation pad 2 arranges ring boss, the space that ring boss and cannon spray head front wall inner surface surround is that above-mentioned atomization forms chamber 22, also the ring of advancing by leaps and bounds to its inner chamber can be set in the sidewall front portion of cannon spray head 1 convex, ring is convex can be blocked atomization formation pad 2, atomization forms on front side of the pad 2 until space of the front portion of cannon spray head 1 and is all above-mentioned atomization formation chamber 22, the spray film spray orifice 11 of diameter much smaller than cannon spray head 1 intracavity diameter is provided with in the middle of the antetheca of described cannon spray head 1, the front portion of described cannon spray head 1 is connected with the shower nozzle 3 that inner chamber is communicated with spray film spray orifice 11, shower nozzle 3 is in column and its front end face is hemispherical, the front end face of shower nozzle 3 and sidewall are evenly equipped with multiple spray holes 31, the rear portion of described cannon spray head 1 is connected with can to the medicinal liquid thrust unit of cannon spray head 1 inner chamber herb liquid extruding.Medicinal liquid thrust unit comprises the promotion cylinder 6 being connected to cannon spray head 1 rear portion, promote to slidably connect catch bar 5 in cylinder 6, catch bar 5 is connected with and stretches into cannon spray head 1 inner chamber and can along the piston 4 of wall slip in cannon spray head 1, sealing gasket is equipped with at the position that catch bar 5 stretches into cannon spray head 1, catch bar 5 is provided with land 51, be equipped with between land 51 and the inwall rear portion promoting cylinder 6 and push up spring 7, the outside promoting cylinder 6 is hinged with pull lever 8, and connecting rod 9 is housed between the rear portion of pull lever 8 and catch bar 5.The liquid injection pipe 12 with its inner space is equipped with at the sidewall rear portion of cannon spray head 1; the fluid injection outer housing 13 of spiral-lock in liquid injection pipe 12 outside the outer wall of cannon spray head 1 be also equipped with; shower nozzle 3 is connected with cover and is contained in shower nozzle outer housing 14 outside shower nozzle; the setting of fluid injection outer housing and shower nozzle outer housing can make this utility model be effectively protected at the turnover position of medicinal liquid when not using, and prevents contamination phenomenon.
This utility model uses like this: during needs of patients medication, manually pull above-mentioned pull lever 8, catch bar 5 is driven to move backward, top spring 7 is compressed, now piston 4 forms pad 2 away from atomization, in hydrojet cylinder, medicinal liquid is injected by liquid injection pipe 12, unclamp pull lever 8, under the effect of top spring 7, catch bar moves forward, medicinal liquid in Pistons's hydrojet cylinder 1 extrudes, because spring 7 can carry out impact extruded fast to it, medicinal liquid enters atomization and forms chamber 22 after liquid pass hole 21, medicinal liquid is when aperture enters in the atomization formation chamber 22 of larger space, and be subject to huge pressure, thus it forms atomization jet flow, at the spray film spray orifice 1 through cannon spray head 1 front end, medicinal liquid forms chamber 22 through small holes from large-area atomization, it is made to be atomized further, be atomized completely in the inner chamber of shower nozzle, spray holes 31 finally by shower nozzle enters the nasal cavity of patient, make medicinal liquid completely and focus of going directly uniformly, reach best therapeutic effect, this utility model is when spraying treatment, automatically spraying is formed by the extruding force of spring, no longer need hand spray, treatment personnel or patient oneself can adjust shower nozzle and stretch into length in nasal cavity, make the treatment position that medicinal liquid reaches best, therapeutic effect is more desirable.
