초록 ▼

A microfluidic valve system includes a substrate, a valve seat a compliant membrane and a mechanically actuable displacement element. The substrate includes first and second channels embedded within it and includes a first layer of material and a second layer of material. The valve seat is in fluid communication with the first and second channels. Portions of the second layer of material form sidewalls of the second channel and the valve seat. The mechanically actuable displacement element applies a mechanical force to the compliant membrane to bring the compliant membrane into sealable contact with the valve seat, thereby closing the valve system.

1. A microfluidic valve system, comprising: a substrate having first and second channels embedded therein and having a first layer of material and a second layer of material;a valve seat in fluid communication with the first and second channels;a compliant membrane; anda mechanically actuable displacement element for applying a mechanical force to the compliant membrane to bring the compliant membrane into sealable contact with the valve seat, thereby closing the valve system, wherein portions of the second layer of material form sidewalls of the second channel and the valve seat. 2. The valve system of claim 1, wherein the substrate comprises a plate with a threaded hole formed therethrough, and wherein the displacement element is positioned in the threaded hole. 3. The valve system of claim 1, wherein the displacement element is manually actuable. 4. The valve system of claim 1, wherein the displacement element comprises a threaded element. 5. The valve system of claim 1, wherein the valve seat comprises a protruding ring axially aligned with the through hole. 6. The valve system of claim 1, further comprising a third layer of material, coupled to the second layer of material and positioned on an opposite side of the second layer of material relative to the first layer of material, wherein the third layer of material forms a portion of a ceiling of the second channel, and the compliant membrane is coupled to the third layer of material on an opposite side of the third layer of material relative to the second layer of material.
