Description

A kind of livestock medicine atomization breathing mask

technical field

The utility model relates to the technical field of medical instruments, in particular to an aerosolized respiratory mask for livestock medicine.

Background technique

In the treatment of many respiratory diseases, many drugs need to be atomized and then enter the respiratory tract through the nasal cavity of livestock to achieve the treatment of lung diseases. When animals wear a mask for the purpose of inhaling aerosolized agents, there are the following technical problems:

(1) The sealing of the mask structure and the sealing between the mask and the animal head

Animals can only inhale large doses of aerosolized drugs if the mask is sealed against the animal's head. If there is a gap in the mask, the gap will enter the air when inhaling, and the aerosol medicine will leak when exhaling. The mask itself has many components connected and assembled. Whether the sealing performance of the assembly connection is good and whether it leaks will also affect the therapeutic effect of breathing.

(2) Minimized dead space

Respiratory masks are primarily designed for the management of breathing gases. The dead space is large, which is not conducive to the exhalation of exhalation, and will be inhaled into the animal's lungs in the next inhalation action. Long-term use, the higher CO2 concentration in the dead space in the exhalation will affect the comfort of the animal and affect the therapeutic effect.
