Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

Please refer to fig. 1, an atomizer convenient for powder charging, comprising an atomizer body, a face mask and an atomization generator connected with the atomizer body, wherein the atomizer body is provided with a powder charging cavity 10, the top of the powder charging cavity 10 is provided with a powder discharging pipe 11 and a powder feeding pipe 12 side by side, the powder discharging pipe 11 is communicated with the face mask, and under the condition of uninterrupted atomization, the powder can be rapidly charged into the powder charging cavity 10 through the powder feeding pipe 12. Because the dosing pipe 12 is only communicated with the medicine charging cavity 10, the atomizer with the medicine charging cavity 10 can realize rapid medicine charging operation, namely the atomization generator can be an ultrasonic generator or a compressed air generator.

Referring to fig. 1 and 2, the nozzle of the dosing tube 12 matches the needle connection port of the syringe. The outer side of the dosing tube 12 is connected with a tube cap 14 which is matched with the tube opening of the dosing tube 12. Be equipped with the lamella 13 in the dosing tube 12, the edge of lamella 13 and the inside wall sealing connection of dosing tube 12, the middle part of lamella 13 is equipped with closed opening 15, and simultaneously, lamella 13 is close to the mouth of pipe of dosing tube 12, reduces the remaining of liquid medicine between the mouth of pipe of lamella 13 and dosing tube 12. In the present embodiment, the closed opening 15 has a cross shape. Obviously, in other embodiments of the present invention, the closed opening 15 may also be a straight line or a closed circular hole.

In this embodiment, the medicine adding mode has two kinds, one kind is the mode that adopts the syringe to inject, and after the syringe inhales the liquid medicine, is connected the syringe needle connector mouth of syringe with the mouth of pipe of adding pencil 12, gets into the chamber 10 of adorning through promoting the liquid medicine, and the diaphragm 13 is opened automatically under the effect of the squeezing force this moment, adds medicine and accomplishes the back, and the diaphragm 13 automatic recovery realizes the shutoff to adding pencil 12. Secondly, the medicine adding mode of the infusion apparatus is adopted, after the needle head of the infusion apparatus penetrates through the closed opening 15, the liquid medicine automatically enters the medicine charging cavity 10, after the medicine adding is completed, the needle head of the infusion apparatus is taken out, the closed opening 15 is automatically closed, the medicine adding is carried out by continuously dripping the medicine into the medicine charging cavity 10 through the infusion apparatus, and the effect of continuously humidifying the trachea can be achieved.

In order to increase the operating range of the operator, in the present embodiment, the atomizer for facilitating charging further includes an extension dosing assembly 20, see fig. 3 and 4. The extension medicine adding assembly 20 comprises an extension tube 21 and a connecting needle 22, wherein a nozzle at one end of the extension tube 21 is matched with a needle head connecting port of the injector, and a nozzle at the other end of the extension tube 21 is connected with the connecting needle 22. When in use, the medicine adding mode of the infusion apparatus does not need to be prolonged, and the medicine adding component 20 is only used for the medicine adding mode of the injector. When the extension medicine adding assembly 20 is used, the connecting needle 22 only needs to extend into the closed opening 15, and the valve 13 can automatically seal the gap between the connecting needle 22 and the valve 13. In order to avoid the damage of the flap 13 caused by the connecting needle 22, in the present embodiment, the tip of the connecting needle 22 is flat.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
