Title:
RESPIRATORY TRACT HUMIDIFICATION PUMP
Document Type and Number:
WIPO Patent Application WO/2018/023504
Kind Code:
A1
Abstract:
A respiratory tract humidification pump comprising: a piston cover (1), a medicinal liquid pool (2), a movable piston (3), a microtiter pump (6), a medicinal liquid outlet (7), and a drive control apparatus. The movable piston (3) is provided within the medicinal liquid pool (2). One extremity of the medicinal liquid pool (2) is connected to the piston cover (1); the other extremity of the medicinal liquid pool (2) is connected to the microtiter pump (6) via a medicinal liquid channel (5). The microtiter pump (6) is connected respectively to the medicinal liquid outlet (7) and to the drive control apparatus via the medicinal liquid channel (5). The drive control apparatus is used for controlling the microtiter pump (6) to execute titration at a preset titration rate, thus allowing the movable piston (3) to move towards the other extremity of the medicinal liquid pool (2) as the volume of a medicinal liquid in the medicinal liquid pool (2) reduces. The present respiratory tract humidification pump allows accurate control of the titration time and flow rate of the medicinal liquid, implements steady output over an extended period, and increases the titration accuracy of the respiratory tract humidification pump.
