System for detection of fluid infusion
First Claim
1. A method of mounting a fluid delivery set onto a pump for monitoring delivery of fluid to a patient, the fluid delivery set having at least a first mounting member of a defined geometry and said pump including a housing and a closure, with said closure having a closed and an open position relative to said housing, said housing further including a rotor for controlling delivery of said fluid, a recess and a sensor substantially adjacent said recess, said sensor of said housing having an actuated and non-actuated state, and said rotor of said housing receiving a portion of said fluid delivery set, the method comprising:
- installing said at least a first mounting member of said fluid delivery set in a predetermined position in the recess of said housing; and
providing said closure in the closed position relative to said housing wherein said closure displaces said at least a first mounting member of said fluid delivery set in a direction of said sensor which causes a change in state of said sensor from the non-actuated to the actuated state.

Abstract
An infusion apparatus includes a pump and a fluid delivery set. The infusion apparatus is adapted to monitor the fluid delivery set for insuring proper placement in relation to the pump. The infusion apparatus further includes a sensor which operates to detect the proper alignment of the fluid delivery set and also the proper operating position of the infusion apparatus. The infusion apparatus includes a cover which is adapted to be in a closed position when the infusion apparatus is in proper operating position. The cover operates to secure the fluid delivery set within the mounted position in the infusion apparatus.

1. A method of mounting a fluid delivery set onto a pump for monitoring delivery of fluid to a patient, the fluid delivery set having at least a first mounting member of a defined geometry and said pump including a housing and a closure, with said closure having a closed and an open position relative to said housing, said housing further including a rotor for controlling delivery of said fluid, a recess and a sensor substantially adjacent said recess, said sensor of said housing having an actuated and non-actuated state, and said rotor of said housing receiving a portion of said fluid delivery set, the method comprising:
-
installing said at least a first mounting member of said fluid delivery set in a predetermined position in the recess of said housing; and providing said closure in the closed position relative to said housing wherein said closure displaces said at least a first mounting member of said fluid delivery set in a direction of said sensor which causes a change in state of said sensor from the non-actuated to the actuated state. - View Dependent Claims (2)

3. An infusion apparatus comprising:
-
a pump having a housing and a closure, with said housing including a rotor, at least one recess and a sensor having an actuated and a non-actuated state, said closure being operatively coupled to said housing and adapted to be pivoted between an open and a closed position relative to said housing; a fluid delivery set mountable on said pump, said fluid delivery set including a tubing section adapted to be received about said rotor and at least a first mounting member of a predefined geometry receivable in a predetermined position within the at least one recess of said housing; and said sensor being responsive to said at least a first mounting member of said fluid delivery set relative to said at least one recess of said housing for monitoring delivery of fluid through said infusion apparatus, wherein when said at least a first mounting member is in the predetermined position within said at least one recess, said closure when pivoted to the closed position relative to said housing is adapted to engage and displace a predetermined amount said at least a first mounting member in a first direction and into a secured position within said recess which causes a change in state of said sensor from the non-actuated to the actuated state, whereby subsequent displacement of said at least a first mounting member a predetermined amount from the secured position in a second or third direction substantially perpendicular the first direction causes a change in state of said sensor from the actuated to the non-actuated state, and whereby subsequent pivotal movement of the closure from the closed position to the open position results in displacement of said at least a first mounting member a predetermined amount from the secured position in a fourth direction generally opposite the first direction which causes a change in state of said sensor from the actuated to the non-actuated state. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)

12. A fluid delivery set for mounting on a pump comprising a tubing section and at least a first mounting member of a predefined geometry;
-
wherein said pump has a housing and a closure, with said housing including a rotor, at least one recess and a sensor having an actuated and a non-actuated state, said closure being operatively coupled to said housing and adapted to be pivoted between an open and a closed position relative to said housing; said tubing section is adapted to be received about said rotor and said first mounting member is receivable in a predetermined position within the at least one recess of said housing; and said sensor is responsive to said at least a first mounting member of said fluid delivery set relative to said at least one recess of said housing for monitoring delivery of fluid through said infusion apparatus, wherein when said at least a first mounting member is in the predetermined position within said at least one recess, said closure when pivoted to the closed position relative to said housing is adapted to engage and displace a predetermined amount said at least a first mounting member in a first direction and into a secured position within said recess which causes a change in state of said sensor from the non-actuated to the actuated state, whereby subsequent displacement of said at least a first mounting member a predetermined amount from the secured position in a second or third direction substantially perpendicular the first direction causes a change in state of said sensor from the actuated to the non-actuated state, and whereby subsequent pivotal movement of the closure from the closed position to the open position results in displacement of said at least a first mounting member a predetermined mount from the secured position in a fourth direction generally opposite the first direction which causes a change in state of said sensor from the actuated to the non-actuated state. - View Dependent Claims (13, 14)
