Abstract

The invention relates to an integrated precise medicine feeding pump, belonging to the medicine feeding pump. Wherein, the inner space of case is mounted with a multi-vibrator piezoelectric pump, whose inlet channel is connected to a porous medicine guide tube; the flexible medicine chamber storage via the flexible medicine chamber is connected to the inlet of pump and inside the case; and said porous medicine guide tube is inside said flexible medicine chamber. The invention has the advantages that: it uses multi-chamber or single chamber multi-vibrator piezoelectric pump to improve the output pressure and flux to make the pressure is higher than the needed pressure in working to confirm the coherence of medicine filling, realize the accurate control and improve the operation safety.

Description

technical field [0001] The present invention relates to a drug delivery pump, in particular to a thin film pump made of multi-piezoelectric oscillators, and a precision drug delivery device which integrates a drug storage part at the inlet of the pump body. Background technique [0002] At present, the quantitative drug delivery device is mainly used in the treatment of diabetes, and its main function is to quantitatively inject insulin to diabetic patients according to preset parameters or according to real-time detected blood glucose concentration, so as to control the blood glucose concentration of diabetic patients. Existing quantitative drug delivery devices for insulin injection are generally composed of disposable drug reservoirs, disposable drug delivery catheters, injection mechanisms, deceleration mechanisms, control parts and other accessories. The existing bolus injection mechanism generally uses a motor to drive the spiral bolus injection mechanism through a dec...
