Adjustable and controllable aerosol inhalation device for small animals

Abstract

The invention discloses an adjustable and controllable aerosol inhalation device for small animals. The device comprises an atomization device; a medicine enrichment pipe is arranged in the atomization device and connected with an external medicine collection bottle through a medicine conduction pipe; the bottom of the atomization device is communicated with a ventilation power device; a medicine collection vessel is arranged at the bottom of the ventilation power device; the atomization device is communicated with a medicine feeding device through an atomized medicine conveying pipeline; and a suction nozzle in the medicine feeding device is used for atomization for the experimental animals. According to the adjustable and controllable aerosol inhalation device for the small animals, while the waking of the animal is ensured, the variety of a medicine can be autonomously selected, the concentration and the dosage of the medicine inhaled by the experimental animal can be accurately controlled, more accurate experimental data can be obtained, and the contact between the body part of the experimental animal and the medicine can be avoided to the greatest extent, so that the experimental result can be reflected most truly.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical experiment devices, in particular to a controllable atomization inhalation device for small animals. Background technique [0002] Animal models play an important role in scientific research such as biomedical and pharmacokinetic studies. In the process of establishing animal models, aerosol inhalation is an ideal route of administration. Atomized inhalation drug administration refers to the atomization of one or more than one medicinal liquid through an atomizing device, and enters the lungs through the respiratory tract, so as to achieve the purpose of administration. Nebulized inhalation administration can directly act on the lungs, effectively avoiding the body's first elimination of drugs, reducing drug loss and adverse reactions to the body, and improving research efficiency. [0003] There are obvious deficiencies in the small animal aerosol inhalation devices used in various resea...

AI Technical Summary

Problems solved by technology

Each time an experiment is conducted, only a single drug can be used, variables such as the type and concentration of the drug cannot be controlled, and the amount of drug inhaled by each experimental animal cannot be accurately known, which not only increases the overall experimental time, but also cannot obtain accurate experimental data
