Drug delivery device for respiratory system

Abstract

The invention relates to the technical field of medical equipment, in particular to a drug delivery device for respiratory system. The device comprises an atomizer, an oxygen tank, a mixing chamber and a mask, a medicine outlet of the atomizer is connected to a medicine inlet of the mixing chamber through a medicine outlet pipe, a medicine inlet valve is arranged at the medicine inlet, the oxygentank is connected to an oxygen conveying port of the mixing chamber through an oxygen conveying pipe, an oxygen conveying valve is arranged at the oxygen conveying port, the medicine inlet and the oxygen conveying port respectively communicate with the inner cavity of a first mixing disc through a feeding pipe, the center of the top of the first mixing disc communicates with an inner cavity of a second mixing disc through a Y-shaped mixing pipe, a mixing overflow hole is formed in the top face of the second mixing disc, a heating pipe and an exhaust fan are arranged on the bottom face and thetop face of the mixing chamber respectively, an oxygen sensor and a temperature sensor are further arranged on the upper middle portion of the mixing chamber, and the oxygen sensor, the temperature sensor, the medicine inlet valve, the oxygen conveying valve, the exhaust fan, the heating pipe and the atomizer are all connected to a controller. The device ensures that medicine mist and oxygen are fully mixed, optimizes the atomization effect, and prevents oxygen intoxication of a patient at the same time.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a respiratory drug delivery device. Background technique [0002] The atomization inhalation method is to use high-speed oxygen flow to make the liquid medicine form a mist, and then inhale it through the respiratory tract to achieve the purpose of treatment. Nebulization therapy is actually a very ideal method for clinical treatment of respiratory diseases. It has been used in the UK as early as the 1950s, and it has been used clinically in my country for nearly 20 years. Because atomized inhalation can directly act on the affected respiratory tract and lungs, compared with oral or intravenous infusion, it has a faster onset and better effect; the local drug concentration is high, but the overall drug dose is small, only dozens of systemic drugs One-third, less adverse reactions. Some atomization equipment is equipped with oxygen tanks to supply oxygen during the ato...

AI Technical Summary

Problems solved by technology

Some atomization equipment is equipped with oxygen tanks to supply oxygen during the atomization process to prevent patients from hypoxia. However, there is no monitoring of the oxygen concentration, and it is impossible to ensure that the atomized medicine and oxygen are mixed evenly. If the oxygen content is too high, it will Oxygen intoxication occurs, which poses a safety hazard
