Encapsulated valve system and method of use

1. An encapsulated valve system for pharmaceutical or biological liquid fluids, said valve system comprising:

a first housing portion having a first facing surface; and

a second housing portion having a second facing surface and configured to be separably coupleable with said first housing portion;

wherein:

said first facing surface includes a first plurality of branch passageways and a common passageway bridging said first plurality of branch passageways formed as a first recess within said first facing surface;

said second facing surface includes a second plurality of branch passageways and a common passageway bridging said second plurality of branch passageways formed as a second recess within said second facing surface, the first and second plurality of branch passageways extending from said common passageway in a single lateral direction;

said first recess and said second recess are shaped and configured to form a conduit passageway shaped and configured to encapsulate a disposable conduit therein;

at least one first aperture is provided in communication with said first plurality of branch passageways, the at least one first aperture dimensioned to receive a first valve element; and

at least one second aperture is provided in communication with said second plurality of branch passageways, the at least one second aperture dimensioned to receive a second valve element;

the valve system further comprising:

a first pinch valve with a first pinching element extending into one of said at least one first aperture provided in communication with said first plurality of branch passageways; and

a second pinch valve with a second pinching element extending into one of said at least one second aperture provided in communication with said second plurality of branch passageways;

wherein:

said at least one first aperture provided in communication with said first plurality of branch passageways is located spaced apart from said at least one second aperture provided in communication with said second plurality of branch passageways; and

said first pinch valve is positioned to pinch only a first side of a conduit disposed within said conduit passageway, and said second pinch valve is positioned to pinch only a second side of the conduit disposed within said conduit passageway, the first side and second side being opposite sides of the conduit.

2. The encapsulated system of claim 1 , further comprising the disposable conduit shaped to be encapsulated within said conduit passageway formed by said first recess and said second recess.

3. The encapsulated system of claim 2 , wherein said disposable conduit is formed of an unreinforced silicone tubing.

4. The encapsulated system of claim 1 , further comprising at least one common passageway aperture is provided in communication with said common passageway.

5. The encapsulated system of claim 4 , further comprising:

a common pinch valve with a pinching element extending into said common passageway aperture;

wherein:

said first branch pinch valve is positioned to control fluid flow through a first branch passageway;

said second pinch valve is positioned to control fluid flow through a second branch passageway different from said first branch passageway; and

said common pinch valve is positioned to control fluid flow through said common passageway.

6. The encapsulated system of claim 5 , further comprising at least one automatically-controlled pinch valve actuator controlling at least one of said first pinch valve or said second pinch valve or said common pinch valve.

7. The encapsulated system of claim 5 , further comprising at least one manually-controlled pinch valve actuator controlling at least one of said first pinch valve or said second pinch valve or said common pinch valve.

8. The encapsulated system of claim 1 , wherein said plurality of branch passageways terminate at respective flange fittings.

9. The encapsulated system of claim 8 , wherein said disposable conduit includes a seal or gasket at least one terminal end thereof dimensioned to fit within a recess in one of said flange fittings.

10. The encapsulated system of claim 1 , wherein said plurality of branch passageways terminate in plain tube endings.

11. An encapsulated valve system comprising:

a first housing portion; and

a second housing portion;

wherein:

said first housing portion and said second housing portion are formed separately and, when facing surfaces thereof are brought into contact, form an inlet passageway, a plurality of enclosed branch passageways including at least first and second branch passageways and a common passageway bridging said inlet passageway and said plurality of enclosed branch passageways including said first and second branch passageways, each of the plurality of enclosed branch passageways including said first and second branch passageways extending from the common passageway and from the first and second housing portions through only a first lateral side thereof;

a disposable conduit is extendable within said inlet passageway, said branch passageways, and said common passageway to be encapsulated therein; and

a common passageway aperture formed in said first housing portion, said common passageway aperture being in communication with said common passageway, said common passageway aperture being positioned between said first and second branch passageways.

12. The encapsulated valve system of claim 11 , further comprising:

a first pinch valve actuator mounted on said first housing portion with a pinching element passing through said common passageway aperture to contact a portion of the disposable conduit within said common passageway.

13. The encapsulated valve system of claim 11 , further comprising at least one valve positioned to gate a fluid medium flowing through the disposable conduit within said plurality of enclosed branch passageways and said common passageway into one or more selected branch passageways.

14. The encapsulated valve system of claim 11 , wherein the disposable conduit is made of unreinforced silicone tubing, said first and second housing portions forming an exoskeleton encapsulating said disposable conduit.

15. The encapsulated valve system of claim 11 , further comprising a disposable conduit encapsulated within said branch passageways and said common passageway, wherein:

said plurality of branch passageways terminate at respective flange fittings; and

said disposable conduit includes a seal or gasket at least one terminal end thereof dimensioned to fit within a recess in one of said flange fittings.
