Liquid moving device for moving liquid back and forth over sensor surface of analytic sensor utilized in bio analytics field, has channel designed in such manner that counter pressure difference opposite to pressure difference is produced

摘要

#CMT# #/CMT# The device (100) has a pressure difference forming device i.e. valveless pump, which forms a pressure difference (8) in a channel (6), to move liquid (2) in a direction (1a) over a pre-determined surface (4) of a channel wall until a pre-determined time, for reducing the developed pressure difference at the pre-determined time. The channel is designed in such a manner that a counter pressure difference opposite to the pressure difference is produced, where the counter pressure difference moves the liquid in a direction (1b) over the pre-determined surface. #CMT# : #/CMT# An independent claim is also included for a method for moving liquid back and forth over a pre-determined surface in a channel. #CMT#USE : #/CMT# Liquid moving device for moving liquid back and forth over a pre-determined surface i.e. sensor surface, of an analytic sensor that is utilized in bio analytics field. #CMT#ADVANTAGE : #/CMT# The channel is designed in such a manner that the counter pressure difference opposite to the pressure difference is produced, where the counter pressure difference moves the liquid in other direction over the pre-determined surface, so that the liquid can be moved back and forth over the pre-determined surface without the need to pump in two directions by the pump. The device is more economical and requires less maintenance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side sectional view of a liquid moving device that is utilized for moving a liquid back and forth over a pre-determined surface. 1a, 1b : Liquid moving direction 2 : Liquid 4 : Pre-determined surface 6 : Channel 8 : Pressure difference 100 : Liquid moving device.
