Abstract
Micro-valve system includes two or more superimposed tubes and a pressing device for fluid control in miniaturized capillary connections. The micro-valve system and method of fabrication can be tailored to the requirements of a wide range of applications; composition, sturdiness and thickness of plastic tubes; and capable of been adapted to the resilient of mechanical pressure and the passing and transport of fluid types.
Claims21
A micro-valve system comprising:
- a first capillary and a second capillary symmetrically positioned in between a first and second support towers and having a space between a first end of the first capillary and a first end of the second capillary;
- the first end of the first capillary being connected to a first end of a sleeve connector;
- the first end of the second capillary connected to a second end of the sleeve connector;
- the second end of the first capillary being supported by the first support tower;
- the second end of the second capillary being supported by the second support tower;
- a casing surrounding said sleeve connector, said casing comprising one or more layers, and
- a compressing system positioned adjacent the sleeve connector, the compressing system configured to compress the sleeve connector to block fluid flow between the first capillary and the second capillary,
- wherein the sleeve connector is formed of a flexible material and wherein said casing sustains pressure applied by said compressing system and protects said sleeve connector.

- the second end of the first capillary being supported by the first support tower;
- and
- a compressing system positioned adjacent the sleeve connector, the compressing system configured to compress the sleeve connector to block fluid flow between the first capillary and the second capillary,
- wherein the sleeve connector is formed of a flexible material and
- wherein the compressing system comprises a pair of poles, the poles being positioned on either side of the connector sleeve, a motorized system operated by a computer moves the poles toward and away from the connector sleeve, the poles contacting the connector sleeve to provide a compressing force to block fluid flow between the first capillary and the second capillary.
