An infusion pump having a tubing clamping section including a movable and a stationary portion. The infusion pump includes at least one sensor for detecting a contact length of tubing within the movable and/or the stationary portion. The infusion pump includes a shuttle having a shuttle stationary and a shuttle moveable portion, and is configured to squeeze a length of the tubing between the shuttle portions. The infusion pump includes a motor connected to the shuttle moveable portion via a shaft. The motor moves the shuttle moveable portion towards and away from the shuttle stationary portion. The infusion pump includes a controller and an encoder that detects a position of the shaft. The controller converts the detected position into a travel distance of the shuttle moveable portion, and calculates a diameter and a thickness of the tubing based on the travel distance and the contact length of the tubing.

An infusion pump comprising: a tubing clamping section including a movable portion and a stationary portion;at least one sensor for detecting a contact length of tubing within at least one of the movable portion and the stationary portion;a shuttle including a shuttle stationary portion and a shu
1. An infusion pump comprising: a tubing clamping section including a movable portion and a stationary portion;at least one sensor for detecting a contact length of tubing within at least one of the movable portion and the stationary portion;a shuttle including a shuttle stationary portion and a shuttle moveable portion configured for squeezing a length of the tubing between the shuttle stationary portion and the shuttle movable portion;a motor connected to the shuttle moveable portion via a shaft, wherein the motor moves the shuttle moveable portion towards and away from the shuttle stationary portion;a controller; andan encoder connected to the motor, wherein the encoder detects a position of the shaft that the controller uses to: (i) convert the position of the shaft detected by the encoder into a travel distance of the shuttle moveable portion, and (ii) calculate a diameter and a thickness of the tubing based upon the travel distance and the contact length of the tubing. 2. The infusion pump according to claim 1, wherein the controller instructs the motor to move the shuttle moveable portion. 3. The infusion pump according to claim 1, further including a target mounted on the other of the moving portion and the stationary portion. 4. The infusion pump according to claim 1, wherein the controller calculates a volume of solution pumped by the infusion pump based upon the diameter and the thickness of the tubing. 5. The infusion pump according to claim 1, wherein the at least one sensor includes a pressure sensor, a sensor array, a switch array, an inductive sensor, or a capacitive sensor. 6. The infusion pump according to claim 1, wherein the shaft includes a lead screw, a ball screw, or a jackscrew. 7. The infusion pump according to claim 1, further including an inlet valve upstream of the shuttle and an outlet valve downstream of the shuttle. 8. An infusion pump comprising: a tubing clamping section comprising a movable portion and a stationary portion; anda controller configured to: (i) control a motor to move the moveable portion toward and away from the stationary portion, the motor connected to the moveable portion via a shaft;(ii) receive from at least one sensor a signal indicative of a contact length of tubing within at least one of the movable portion and the stationary portion;(iii) receive from an encoder a signal indicative of a position of a shaft connected to the motor;(iv) determine a travel distance of the moveable portion based upon the position of the shaft detected by the encoder; and(v) calculate a diameter and a thickness of the tubing based upon the travel distance and the contact length of the tubing. 9. The infusion pump according to claim 8, wherein the controller includes a computer program on a computer-readable disk for determining the travel distance and calculating the diameter and the thickness of the tubing. 10. The infusion pump according to claim 8, wherein the controller instructs the motor to move the moveable portion to adjust a fluid flow through the tubing. 11. The infusion pump according to claim 8, wherein the motor includes a positive displacement pump or a linear actuator for manipulating the tubing to control a medication flow through the tubing. 12. The infusion pump according to claim 8, wherein the movable portion is a first platen and the stationary portion is a second platen. 13. The infusion pump according to claim 8, wherein the controller: (i) determines the tubing is fully compressed when the contact length of tubing stops changing as the moveable portion is moved toward the stationary portion, and (ii) stops the motor upon the fully compressed determination. 14. A method of measuring tubing comprising: compressing the tubing between opposed surfaces of a fixture;receiving a signal indicative of a position of a shaft of a motor compressing the tubing;receiving a signal indicative of a contact length of the tubing lying against at least one of the opposed surfaces;determining an amount of compression of the tubing based upon the position of the shaft; andcalculating at least one of a diameter and a thickness of the tubing based upon the contact length and the amount of compression. 15. The method according to claim 14, further including loading the tubing into the fixture before compressing the tubing. 16. The method according to claim 14, further including calculating a volume of solution pumped through the tubing based upon the calculated diameter and thickness of the tubing. 17. The method according to claim 14, further including controlling a medication flow through the tubing based upon the calculated diameter and thickness of the tubing. 18. The method according to claim 14, further including calculating an inner diameter of the tubing based upon the contact length and the amount of compression. 19. The infusion pump according to claim 14, further including generating the signal indicative of the position of the shaft. 20. The method according to claim 14, further including generating the signal indicative of the contact length of the tubing.
