Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Fig. 1 is to 5.
A kind of cavity atomized medicine introducing device, including shower nozzle 2.Described shower nozzle 2 is cylindrical shape, and front end is closed, and in center
It is provided with the nozzle 1 of inside and outside insertion.The diameter of this nozzle 1 is about 0.1mm, makes current be scattered water smoke when this nozzle 1 sprays
Shape granule, reaches the effect of atomization.The front end being socketed in grug transportation tube 3 of the back-end sealing of described shower nozzle 2, and by described grug transportation tube
3 rear end is connected with syringe adapter 5, thus, using syringe, liquid medicine can be injected grug transportation tube 3, then spray through shower nozzle 2.
It is provided with a unsteady flow block 6 that can change the direction of a stream of water in described shower nozzle 2.This unsteady flow block 6 is positive six prismsby shape, and length is less than institute
State the length of shower nozzle 2.It is connected to described shower nozzle 2 inwall, between its front end and described shower nozzle 2 blind end in this unsteady flow block 6 axial direction
Form spray chamber 7, rear end is resisted against the front end of described grug transportation tube 3, makes between each side of this unsteady flow block 6 and shower nozzle 2 inwall
Form water stream channel, the liquid medicine from grug transportation tube 3 is become multiply, and increases pressure.The front end of described unsteady flow block 6 is additionally provided with three
Individual fan blade shape geosynclinal block 8, the shapes and sizes all same of each geosynclinal block 8, and equal in the same direction centered on the longitudinal axis of described unsteady flow block 6
Even distribution, makes to form shape identical arc water stream channel between each two geosynclinal block 8, and inflow current therein can be made to form spiral
The turbulent flow of formula.The rear end face of described unsteady flow block 6 is provided with 6 projections 9.Each projection 9 is cylinder, and size is identical, and
It is uniformly distributed centered on the longitudinal axis of described unsteady flow block 6.Preferably, this raised diameter is about 0.3mm.Described raised 9 support
Lean against on the front end face of described grug transportation tube 3, make to form space between unsteady flow block 6 rear end face and grug transportation tube 3 end face, be easy to liquid medicine and lead to
Cross.
Described spray chamber 7 includes ante-chamber 10 and back cavity 11.Described ante-chamber 10 is cone, and described back cavity 11 is truncated cone-shaped,
And the small end of this back cavity 11 is connected with the rear end of described ante-chamber 10.The cone angle of described ante-chamber 10 is more than the circle of described back cavity 11
Coning angle.Preferably, the coning angle of described ante-chamber is about 90 °, and the coning angle of described back cavity is about 70 °.
It is provided with spring in the tube wall of described grug transportation tube 3, can easily bend.The outer warp of this grug transportation tube 3 is about 12.5mm,
Internal diameter is about 1mm, not only can easily stretch in the cavitys such as nasal cavity and be treated, and ensures that administration is rapid and abundant.Should
The length of grug transportation tube 3 can make different specifications as needed, meets the Treatment need of different cavitys.
Described syringe union joint 5 is funnel-form, and the head of size and syringe is adapted, its small end and described grug transportation tube
3 connections, big end closely can be connected with the syringe meeting GB, it is thus possible to by syringe input liquid medicine, not only make to
Medicine is convenient, and dosage can be made more accurate.Meanwhile, can also live outside the small end of described syringe union joint 5
Dynamic socket nasal obstruction 4, when conveniently to intranasal administration, described nasal obstruction is fixed on the nostril of patient, so that this device is fixed.
