Description
Technical field
The utility model relates to field of medical device more particularly to a kind of inhalers.
Background technique
Daily during seeing a doctor, often it is used in the mode of atomization and is used as medicine by nasal cavity and being used as medicine into mode,
This mode is primarily adapted for use in children, old man or by esophagus inconvenience into the patient of medicine, generally require external with atomizer
The mode of device of being used as medicine is used as medicine, since the volume for the device that is used as medicine is larger, higher cost, and in use, very important person is pinned with hand
The device that is used as medicine uses, and needs to press always, and until medicinal atomized finish can just remove, use is very inconvenient, and is used as medicine
The cost of device is also higher.
Utility model content
The utility model discloses a kind of inhalers, with so as to solve the deficiencies in the prior art.
To solve the above problems, the technical solution of the utility model is:
A kind of inhaler, including inner cylinder, outer cylinder and plug, inner barrel and outer barrel are cylindrical cavity body structure, and outer cylinder is logical
It crosses and is threadably mounted on inner cylinder, inner cylinder is made of the pedestal of cylindrical cylinder and bottom, and chassis interior is provided with step structure,
It is provided with the also orthogonal sealing surface of cylinder, plug on lateral surface to be mounted at the stepped hole of pedestal, the top setting of inner cylinder
There is top through-hole, the lower position of the cylinder of inner cylinder is provided at least two lower through-holes, the threaded joints of inner barrel and outer barrel
Between lower through-hole and sealing surface, the bottom of outer cylinder is provided with sealed bottom protrusion, and sealed bottom protrusion connects with sealing surface
Touching sealing, the threaded joints top of inner cylinder are provided with sealing ring, and sealing ring is located at the lower section of lower through-hole, sealing ring and
Outer tube inner wall interference fit, plug and inner cylinder are interference fit, and the diameter of cylinder is greater than 15mm.
The beneficial effects of the utility model are: this inhaler very easily can be inserted into nasal cavity by this inhaler
In, it can be directly used as medicine by external atomizer, also be not required to very important person and pinned with hand always, after being used as medicine, removed, and
And this inhaler is small in size, and it is at low cost, i.e., it is economical and applicable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is enlarged diagram at the A in Fig. 1 of the utility model；
In figure: 1- inner cylinder, 2- outer cylinder, 3- plug, 11- pedestal, 12- enter nose, 13- lower through-hole, and the top 14- leads to
Hole, 15- sealing ring, 16- sealing surface, 21- sealed bottom protrusion.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Referring to attached drawing 1-2, the utility model includes inner cylinder 1, outer cylinder 2 and plug 3, and inner cylinder 1 and outer cylinder 2 are cylindrical
Cavity body structure, by being threadably mounted on inner cylinder 1, inner cylinder 1 is made of outer cylinder 2 pedestal 11 of cylindrical cylinder 12 and bottom,
Pedestal 11 is internally provided with step structure, and the also orthogonal sealing surface 16 of cylinder 12, plug 3 are provided on lateral surface and is mounted on
At the stepped hole of pedestal 11, the top of inner cylinder 1 be provided with top through-hole 14, the lower position of the cylinder 12 of inner cylinder 1 be provided with to
The threaded joints of few two lower through-holes 13, inner cylinder 1 and outer cylinder 2 between lower through-hole 13 and sealing surface 16, outer cylinder 2
Bottom is provided with sealed bottom protrusion 21, and sealed bottom protrusion 21 contacts sealing with sealing surface 16, on the threaded joints of inner cylinder 1
Portion is provided with sealing ring 15, and sealing ring 15 is located at the lower section of lower through-hole 13, and sealing ring 15 and outer tube inner wall are interference fitted,
Plug 3 and inner cylinder 1 are interference fit, and the diameter of cylinder 12 is greater than 15mm.
In practical applications, inner cylinder 1 and outer cylinder 2 are cylindrical cavity body structure, and outer cylinder 2 is by being threadably mounted at inner cylinder
On 1, inner cylinder 1 is made of the pedestal 11 of cylindrical cylinder 12 and bottom, and pedestal 11 is internally provided with step structure, on lateral surface
It is provided with the also orthogonal sealing surface 16 of cylinder 12, plug 3 to be mounted at the stepped hole of pedestal 11, the top setting of inner cylinder 1
There is top through-hole 14, the lower position of the cylinder 12 of inner cylinder 1 is provided at least two lower through-holes 13, the spiral shell of inner cylinder 1 and outer cylinder 2
For line connecting portion between lower through-hole 13 and sealing surface 16, the bottom of outer cylinder 2 is provided with sealed bottom protrusion 21, sealed bottom
Protrusion 21 contacts sealing with sealing surface 16, and the threaded joints top of inner cylinder 1 is provided with sealing ring 15, and sealing ring 15 is located at
The lower section of lower through-hole 13, sealing ring 15 and outer tube inner wall are interference fitted, before use, the two is sealing, to guarantee inner cylinder
Do not invaded by external bacterium, when in use, need to remove outer cylinder 2 from inner cylinder 1, cylinder 12 be then inserted into nasal cavity
In, it is inserted into pipe outside the stepped hole that drug passes through 1 lower part of inner cylinder and is used as medicine, drug then passes through the top through-hole on 1 top of inner cylinder
14 enter nasal cavity, and lower through-hole 13 is then the venthole with atmosphere, so that the extra drug without sucking nasal cavity is discharged to sky
In gas, the diameter of cylinder 12 is greater than 15mm, so that inner cylinder 1 will not be dropped out from nasal cavity due to self weight, such manpower
