Problems solved by technology

In this way, the atomized tablet must be cleaned after each administration. Too many cleaning steps will not only cause inconvenience to the user, but also increase the loss of the atomizing device and accelerate the aging of the atomized tablet. Or if the atomizer breaks down, the entire atomizer will be discarded
At the same time, as a component of the atomizer, the atomizer is exposed to the environment for a long time, and is easily polluted by various harmful substances such as bacteria, fungi, and antibiotics. Even after disinfection, the pollutants cannot be completely removed. Atomization of drug solutions is very unfavorable
In addition, traditional nebulizers are used to atomize drugs, which is prone to cross-contamination during treatment with different drugs, which greatly affects the therapeutic effect of diseases

Embodiment 1

[0048] This embodiment provides a drug storage and atomization device for nebulized inhalation and administration, which consists of three parts: a medicine cup module, an atomization module, and an isolation component. The drug storage and atomization device for atomized inhalation and administration can be used as an independent device. After connecting to the host of the atomization device, it can directly atomize the drug in the medicine cup module, and then through the device connected to the device Nebulizing face mask or mouthpiece to administer the drug to the patient. The isolation part is located between the medicine cup module and the atomization module, and is used to allow the medicine liquid to contact the atomization part of the atomization module only when nebulizing drug administration; The atomization device has an atomized drug delivery state. In the atomized drug delivery state, the isolation part is pulled away, removed or destroyed, and the drug solution ...

Embodiment 2

[0059] Refer to attached image 3 As shown, the present embodiment is basically the same as embodiment 1, and the difference with embodiment 1 is only:

[0060] The medicine cup module and the atomization module 3 that are separable from each other are adopted and used after combination. There is no packaging film on the medicine cup module. At this time, the medicine liquid is mainly isolated from the outside through the packaging cover 21, and the packaging is broken. After the cover 21, it is integrated with the atomization module 3 and connected to the host of the atomization device to realize the atomization of the liquid medicine.

Embodiment 3

[0062] Refer to attached image 3 As shown, the present embodiment is basically the same as embodiment 1, and the difference with embodiment 1 is only:

[0063] The medicine cup 1 and the atomization module 3 are assembled as a whole during manufacture and cannot be separated during medicine storage and transportation. The medicine cup module does not contain the packaging cover 21, packaging film 22 and inner flange 121, but A diaphragm layer 23 is provided on the surface of the atomizing sheet 30 of the atomization module 3 , the atomization module 3 is plugged into the outer flange 122 , and the first conductive probe 123 and the second conductive probe 35 are directly connected. When in use, the diaphragm layer 23 is removed or destroyed, so that the drug solution is in direct contact with the atomizing sheet 30, and after connecting to the host of the atomizing device without the atomizing sheet 30, the liquid drug in the medicine cup module can be directly atomized. cha...

Abstract

The invention discloses a medicine storage and atomizing device for aerosol inhalation administration. The medicine storage and atomizing device for aerosol inhalation administration comprises a medicine cup module, an atomizing module and an isolating component, wherein the medicine cup module comprises a medicine cup; the medicine cup is provided with a cavity for containing liquid medicine; an atomizing opening which communicates with the cavity is formed in the medicine cup; the atomizing module comprises an atomizing piece which is used for atomizing the liquid medicine; the isolating component is positioned between the atomizing opening and the atomizing module and is used for allowing the liquid medicine to be in contact with the atomizing piece only during aerosol administration; when the medicine storage and atomizing device is in an aerosol administration state, the isolating component is drawn, removed or damaged, and the liquid medicine in the medicine cup is in contact with the atomizing piece; the medicine cup module further comprises a first connecting component which is connected with an atomizing equipment main body; and the atomizing module further comprises a second connecting component which is connected with an atomizing mask or a suction nozzle. A cleaning step after atomizing of the medicine is omitted, medicine cross contamination caused by unthorough cleaning is avoided, loss of the atomizing equipment main body is reduced, and the service life of the atomizing equipment main body can be prolonged.

Description

technical field [0001] The invention belongs to the field of atomized inhalation drug administration, in particular to a drug storage and atomization device for atomized inhalation drug delivery. Background technique [0002] Inhalation therapy plays an important role in alleviating respiratory diseases such as asthma, chronic obstructive pulmonary disease and respiratory tract infection. For the treatment of specific diseases, inhalation administration has advantages over other administration methods, especially some are easily degraded in the intestinal tract, Macromolecular drugs affected by the hepatic first-pass effect are more suitable for inhalation administration to reach the respiratory area of ​​the lungs. Inhalation Administration There are currently three methods of inhalation administration: dose metered inhaler (MDI), dry powder inhaler (DPI) and nebulizer (nebulizer). Among them, nebulized inhalation drug delivery has the advantages of good nebulization effec...
