Title:
泡で動かされる弁、弁システム、および、弁を流れる流体を制御する方法
Document Type and Number:
Japanese Patent JP4531409
Kind Code:
B2
Abstract:
A bubble-actuated valve (100) with latching is used to regulate fluid flow, especially the controlled delivery of drugs or other bioactive agents or compounds. The bubble-actuated valve utilizes the bubble (200) to move a solid object (106) that does the actual blocking of the flow channel (110) to regulate the flow of liquid through the valve. The bubble-actuated valve may also include a latching mechanism. One such latching mechanism utilizes the capillary attraction between the solid object and neighbouring walls to latch the solid object in place when the valve is not actuated.
