Title:
LIQUID FLOW MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/132942
Kind Code:
A1
Abstract:
Disclosed is a liquid flow measuring device, with the top thereof being provided with a dropping pipette (18) in the shape of a dropping funnel, wherein a pressure channel (112) in communication with the interior is provided at the periphery of a dropping pipette body (10), a pressure sensing module (30) is provided at an outer end of the pressure channel (112), a pressure communication tube (20) is provided right below the liquid dropping pipette (18), and the bottom end of the pressure communication tube (20) extends to the position close to an inner end of the pressure channel (112). When used in a micro flow measurement pipeline, the device can be connected in series to a small flow pipeline; and when used in an infusion system, the device is connected in series to a medicinal solution infusion pipeline, and during infusion, the medicinal solution enters the dropping pipette body (10), and the pressure sensing module (30) detects the number of drops of the medicinal solution and then transfers this information to a hospital background computer or a built-in single chip (101) for calculation, so as to calculate the flow velocity and flow rate of infusion and determine whether the infusion stops or backflow occurs, thereby achieving the effect of automatically monitoring the infusion process to avoid the occurrence of accidents.
