Peristaltic pump

Abstract

A peristaltic pump for pumping, controlling flow, and siphoning fluid. The pump draws fluid through a tube by using rollers and releases pressure from the tube to form a siphon by opening a bypass door. A rotatable cap provides strength, the ability to rapidly change tubing, as well as locking the bypass door in place for various modes of operation.

I claim: 
     
         1 . A peristaltic pump, comprising:
 a body having a sidewall;   a rotary pump disposed in the body;   the rotary pump comprising a plurality of rollers disposed on a frame that rotates about a central post;   the rotary pump comprising an actuator in operable connection with the plurality of outer rollers;   a tube in operable connection with the plurality of outer rollers, such that engaging the actuator creates suction within the tube; and   wherein a section of the sidewall is a removable bypass door.   
     
     
         2 . The peristaltic pump of  claim 1 , wherein the removable bypass door can be fixed in an open or closed position to control the flow of a fluid through the tube. 
     
     
         3 . The peristaltic pump of  claim 1 , wherein the frame comprises an upper and lower section joined by a plurality of posts,
 wherein the posts form an axel for which the outer rollers rotate thereon; and   wherein the actuator is affixed to the upper or lower section of the frame to rotate the rotary pump.   
     
     
         4 . The peristaltic pump of  claim 1 , wherein the rotary pump has the central post for receiving a central gear;
 wherein the outer rollers have gear teeth thereon; and   wherein the central gear is in meshed contact with the gear teeth on the plurality of outer rollers.   
     
     
         5 . The peristaltic pump of  claim 1 , wherein the removable bypass door is removably secured in the closed position by a cap; and
 wherein the cap is secured to the sidewall of the body by a retention profile that allows the cap to rotate.   
     
     
         6 . The peristaltic pump of  claim 1 , wherein each roller of the plurality of rollers are toothed in a herringbone pattern. 
     
     
         7 . A peristaltic pump, comprising:
 the body having a sidewall;   the rotary pump disposed in the body;   the rotary pump comprising the plurality of outer rollers disposed on a frame that rotates about the central post;   the tube in operable connection with the plurality of outer rollers, such that engaging the actuator creates suction within the tube; and   the cap rotatably attached to the sidewall of the body.   
     
     
         8 . The peristaltic pump of  claim 7 , wherein the section of the sidewall is a removable bypass door, and
 wherein the removable bypass door can be fixed in an open or closed position by rotating the cap.   
     
     
         9 . The peristaltic pump of  claim 7 , wherein the frame comprises an upper and lower section joined by the plurality of posts,
 wherein the posts form an axel that the outer rollers rotate thereon; and   wherein the actuator is affixed to the upper or lower section of the frame to rotate the rotary pump.   
     
     
         10 . The peristaltic pump of  claim 7 , wherein the rotary pump has the central post for receiving the central gear;
 wherein the outer rollers have gear teeth thereon; and   wherein the central gear is in meshed contact with the gear teeth on the plurality of outer rollers.   
     
     
         11 . The peristaltic pump of  claim 7 , wherein each roller of the plurality of outer rollers are toothed in the herringbone pattern. 
     
     
         12 . A peristaltic pump, comprising:
 the body having a sidewall;   the rotary pump disposed in the body;   the rotary pump comprising the plurality of outer rollers disposed on the frame;   the rotary pump comprising the actuator in operable connection with the plurality of outer rollers; and   the tube in operable connection with the plurality of outer rollers, such that engaging the actuator creates suction within the tube.   
     
     
         13 . The peristaltic pump of  claim 12 , wherein the frame comprises the upper section and the lower section joined together by the plurality of posts. 
     
     
         14 . The peristaltic pump of  claim 12 , wherein the rotary pump comprises the central gear meshed with the plurality of outer rollers. 
     
     
         15 . The peristaltic pump of  claim 12 , wherein the central gear is affixed to the actuator. 
     
     
         16 . The peristaltic pump of  claim 12 , wherein the section of the sidewall is the removable bypass door. 
     
     
         17 . The peristaltic pump of  claim 12 , wherein the removable bypass door is removably securable in the closed position through rotation of the cap; and
 wherein the cap is securable via a retention profile defined between the cap and the sidewall of the body.   
     
     
         18 . The peristaltic pump of  claim 12 , wherein each roller of the plurality of rollers is toothed. 
     
     
         19 . The peristaltic pump of  claim 12 , wherein the cap is disposed on the top surface thereof, wherein the cap is rotatable relative to the body.
