Title
(EN) Quantitative liquid delivery system
(ZH) 一种液体定量输送装置
Abstract
(EN)
The invention discloses a quantitative liquid delivery system. The system comprises a shell and a cavity head. A holding mechanism, a control mechanism and a connection end surface are arranged outside of the shell, a transmission mechanism, a power mechanism and a power module are arranged in the shell, the transmission mechanism is driven by the power mechanism to produce linear motion, the power mechanism is connected with the power module, and the control mechanism controls the power mechanism to act. The cavity head comprises a liquid outlet end and a liquid storage with an openable end,and a micro device used for only penetrating through the skin cuticle is arranged on the upper surface of the liquid outlet end; liquid is arranged in the liquid storage, the openable end of the liquid storage is connected with the liquid outlet end, the other end of the liquid storage is connected with the connection end surface of the shell and connected with the transmission mechanism under theaction of pressure. By means of the quantitative liquid delivery system, synchronous drug delivery can be achieved, the drug delivery efficiency can be obviously improved, and the production and preparation cost is reduced.
