Document Type and Number:
WIPO Patent Application WO/2021/129782
Kind Code:
A1
Abstract:
A liquid taking device, a medicine bottle assembly and a liquid taking method. The liquid taking device comprises a cover body (1'), a switching component (30') and a liquid taking pipe (4'); the liquid taking pipe (4') is mounted outside the cover body (1') by means of the switching component (30'); when the switching component (30') is at a first position, an inlet (401') of the liquid taking pipe (4') is in communication with the other end of a liquid taking channel (104'); when the switching component (30') is at a second position, the liquid taking channel (104') is disconnected from the inlet (401') of the liquid taking pipe (4'); and the liquid taking device further comprises an air return channel, for air return of a liquid-containing cavity of a medicine bottle body (8') during or after liquid taking. When the liquid taking device takes a liquid, the cover body (1') does not need to be opened, and by providing a measuring range of the liquid taking pipe (4'), quantitative liquid taking can be achieved, thereby greatly reducing the possibility of contact between the external environment and the liquid in the medicine bottle body (8'), reducing the occurrence of contamination of the medicine liquid inside the medicine bottle body (8'), and facilitating ensuring the effectiveness of the medicine and preventing children from opening. Furthermore, the liquid taking device is provided with the air return channel, and can enable air return of the liquid-containing cavity of the medicine container body (8') during or after a liquid taking process.
