Peristaltic pump head with hybrid rollers and tubing manifold

A peristaltic pump head comprising:

• a first housing being adapted to receive a first flexible tube having a first curved wall, said first housing being adapted to secure said first flexible tube within said first housing;
• a first roller assembly being rotatable within said first housing about a first axis through said first housing, said first axis being coaxial to said first curved wall, said first roller assembly comprising:
• at least two compression rollers being peripherally spaced where each of said compression rollers coming successively into contact with said first flexible tube during rotation of said first roller assembly with successive compression rollers being operative to compress two portions of said first flexible tube against said first curved wall to confine a first finite volume of a fluid in said first flexible tube;
• whereby the fluid in the first flexible tube is moved through said first flexible tube by rotation of said first roller assembly;
• and
• a first tubing manifold with the first housing, the first tubing manifold is configured for allowing a fixed length of said first flexible tube in the first housing by providing a fixed connection point for a first end of the first flexible tube about a first entrance of the first housing and a fixed connection point for a second end of the first flexible tube about a first exit of the first housing;
• wherein the first tubing manifold including:
• a first bracket attached to a first side of the first housing, the first bracket extending from the first side of the first housing away from the first entrance and the first exit;
• a first mounting flange extending perpendicular to the first bracket in front of the first entrance and the first exit;
• the fixed connection point for the first end of the first flexible tube and the fixed connection point for the second end of the first flexible tube are attached on the first mounting flange, wherein the first mounting flange is configured to position the fixed connection point for the first end of the first flexible tube in line with the first entrance of the first housing and the fixed connection point for the second end of the first flexible tube in line with the first exit of the first housing;
• wherein:
• the first bracket of the first tubing manifold including a first adjustable connection to the first side of the first housing, the first adjustable connection is configured for allowing the first bracket to adjust the first mounting flange towards and away from the first housing, whereby a first connection length can be adjusted between the fixed connection point for the first end of the first flexible tube and the first entrance of the first housing and the fixed connection point for the second end of the first flexible tube and the first exit of the first housing, whereby the first bracket is configured to be adjusted for properly tensioning the first flexible tube around the first roller assembly;
• the first adjustable connection of the first bracket to the first side of the first housing is configured to allow the first bracket to rotate about the first side of the first housing, wherein the first bracket rotating up or down about the first side of the first housing is configured to aid in allowing the changing out of the first flexible tube from the first housing;
• wherein the first adjustable connection of the first tubing manifold to the first side of the first housing including:
• a first longitudinal slot in the first bracket of the first tubing manifold;
• a first base plate affixed to the first side of the first housing with a first threaded hole therein;
• and
• a first screw with a first knob handle configured to go through the first longitudinal slot and engage the first threaded hole in the first base plate, wherein, the first screw is configured to be screwed into the first threaded hole via the first knob handle for securely affixing the first bracket about the first side of the first housing, and the first screw is configured to be loosened via the first knob handle for adjusting the first mounting flange towards and away from the first housing, or for rotating the first bracket about the first side of the first housing for changing out of the first flexible tube from the first housing.

A peristaltic pump head comprising:

• a first roller assembly being rotatable within said first housing about a first axis through said first housing, said first axis being coaxial to said first curved wall, said first roller assembly comprising:
• at least two compression rollers being peripherally spaced where each of said compression rollers coming successively into contact with said first flexible tube during rotation of said first roller assembly with successive compression rollers being operative to compress two portions of said first flexible tube against said first curved wall to confine a first finite volume of a fluid in said first flexible tube;
• at least one hybrid roller being peripherally spaced between said compression rollers where each of said hybrid rollers coming into contact with said first flexible tube during rotation of said first roller assembly with said hybrid rollers being operative to partially decompress said first flexible tube and guide said first flexible tube to stay centered with said compression rollers, said hybrid rollers being operative to initiate decompression of said first flexible tube to return to a partial compression dimension;
• whereby the fluid in the first flexible tube is moved through said first flexible tube by rotation of said first roller assembly;
• and
• a first tubing manifold with the first housing, the first tubing manifold is configured for allowing a fixed length of said first flexible tube in the first housing by providing a fixed connection point for a first end of the first flexible tube about a first entrance of the first housing and a fixed connection point for a second end of the first flexible tube about a first exit of the first housing, wherein the first tubing manifold including:
