Detailed Description

This patent is described in further detail below with reference to the accompanying drawings:

referring to fig. 1-4, the embodiment of the present invention relates to a micro-atomized vaccine aerosol preparation device for inhalation, which comprises an atomizing cup, wherein the atomizing cup comprises an atomizing cup body 1 and a liquid inlet 1.1 arranged on the top of the atomizing cup, and an atomizing sheet is arranged in a cavity below the liquid inlet 1.1. The atomizing cup is provided with a liquid transfer device 10, the liquid transfer device 10 comprises a conical suction head 10.1, and the liquid inlet 1.1 is a conical cavity with the same taper as the conical suction head 10.1. The conical suction head 10.1 of the liquid transfer device 10 is inserted into the liquid inlet 1.1 in the deepest state, and the end part of the conical suction head 10.1 keeps a certain gap with the atomizing sheet 4 and is close to the middle part of the top surface of the atomizing sheet 4. Therefore, the precise and quantitative vaccine dropping into the atomizing cup can be ensured, and the waste caused by wall hanging of the vaccine can be reduced.

Further, an exhaust groove is formed in the conical inner side wall of the liquid inlet 1.1, and the upper end of the exhaust groove extends to the upper end edge of the liquid inlet 1.1. In the process that a conical suction head of the liquid transfer device is inserted into the liquid inlet of the atomizing cup, the conical suction head 10.1 and an exhaust groove on the liquid inlet 1.1 form an exhaust channel communicated with external air pressure and a cavity below the liquid inlet 1.1. Can guarantee that atmospheric pressure in the cavity of inlet 1.1 below is unanimous with external atmospheric pressure, can avoid thereby pipettor 10 extrudees atomizing piece 4 at the inside air pressure increase of dropping liquid in-process atomizing cup, influences atomizing piece 4's performance.

Still further, the exhaust grooves comprise 4 semicircular exhaust grooves which are uniformly arranged, and the lower ends of the exhaust grooves extend downwards to the bottom of the liquid inlet 1.1.

Preferably, the external diameter of the thicker rear end of the conical suction head 10.1 is larger than the internal diameter of the upper end of the liquid inlet 1.1, and the distance between the end of the conical suction head 10.1 which is inserted into the liquid inlet 1.1 in the deepest state and the top surface of the atomizing plate 4 is less than 3 mm. Because the inner wall of the liquid inlet 1.1 is in a taper shape consistent with the taper of the conical suction head 10.1, the front end of the conical suction head 10.1 which is inserted into the liquid inlet 1.1 is thin and cannot be blocked, when the conical suction head 10.1 is continuously inserted downwards until the distance from the top surface of the atomizing sheet 4 is less than 3mm, the outer diameter of the thick rear end of the conical suction head 10.1 is larger than the inner diameter of the upper end of the liquid inlet 1.1, and therefore the conical suction head 10.1 cannot be continuously inserted downwards. Thus, the lowest end of the conical suction head 10.1 is ensured to be close to the top surface of the atomizing plate 4 and not to contact the atomizing plate 4. The conical suction head 10.1 drips a trace amount of vaccine on the contact atomizing sheet 4, and the vaccine can not be stuck on the inner wall of the liquid inlet 1.1 basically, so that the precise and quantitative amount of the vaccine dripped into the atomizing cup is ensured, and the waste caused by wall hanging of the vaccine can be reduced.

Specifically, the method comprises the following steps: the atomizing cup further comprises a spray head 7, an upper sealing ring 3, a lower sealing ring 5, a sealing gasket 6 and a PIN needle 2, wherein the sealing gasket 6, the lower sealing ring 5, an atomizing sheet 4 and the upper sealing ring 3 are sequentially arranged on the top surface of the spray head 7 from bottom to top and are connected into a whole through a self-tapping screw 8, and a hole where the self-tapping screw 8 is located can be plugged by a screw plug 9 as required. 2 PIN needles 2 are installed on 4 borders of atomizing piece, and the upper end of 2 PIN needles 2 upwards inserts atomizing cup internal fixation, and the electric contact looks crimping on 2 PIN needles 2's bottom and the atomizing piece realizes being connected between atomizing piece and the electric interface.

When the aerosol sprayer is used, the nozzle 7 of the atomizing cup is inserted into the air inlet one-way valve 11.1 on the mist storage tank body 11, so that the air inlet one-way valve 11.1 is opened, and aerosol atomized in the atomizing cup is filled into the mist storage tank body 11. When a patient holds the mist outlet at the front end of the mist outlet storage tank body 11 in mouth to inhale, the atmospheric pressure pushes the air inlet one-way valve 11.1 open, so that air flow enters the mist storage tank body 11 to drive aerosol in the mist storage tank body 11 to enter the respiratory tract of the patient together.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can make changes, modifications, additions or substitutions within the scope of the present invention, which also falls into the protection scope of the present invention.
