Document Type and Number:
WIPO Patent Application WO/2021/135716
Kind Code:
A1
Abstract:
A disposable wearable microfluidic continuous drug administration system, comprising an elastic drug storage chamber (1) for pressing and storing a drug liquid; one end of the elastic drug storage chamber (1) is connected to a drug discharge tube, the end of the drug discharge tube away from the elastic drug storage chamber (1) is connected to a first microflow channel and a second microflow channel for shunting the drug liquid, an adjustment mechanism is connected between the first microflow channel and the second microflow channel, a first valve (2) and a second valve (3) are respectively provided at two side positions of the adjustment mechanism on the surface of the first microflow channel, and a third valve (4) and a fourth valve (5) are respectively provided at two side positions of the adjustment mechanism on the surface of the second microflow channel. By using the elastic and soft drug storage chamber (1), the drug liquid has a certain impulsive force, facilitating injection of the drug liquid into a human body; in addition, the adjustment mechanism is provided between two microflow channels, and multiple micro-valves are respectively provided on the two microflow channels; the injection amount of the drug liquid can be controlled by controlling the on/off of the micro-valves at different positions, facilitating use by a patient, and reducing the effect on the life of the patient.
