Abstract

A system for sensing medicament delivery and transmitting an operation modification signal having at least two separable components is disclosed. The system includes a flow sensor having an inlet to couple to a fluid source, an outlet for delivering fluid from the fluid source to a patient, at least one sensor to characterize at least one attribute of the fluid, and at least one pin in in electrical communication with the sensor. The system includes a second component having a base having a contact, a controller in electrical communication with the contact that generates an operation modification signal in response to an attribute matching a condition specified by a rule, a transmitter for transmitting the operation modification signal to a device, the operation modification signal, when received by the device, causing the device to modify at least one operating parameter, and a cross-component electrical circuit.

First claim

What is claimed is:

1. A system for sensing medicament delivery and transmitting an operation modification signal having at least two separable components comprising:
a first component comprising a flow sensor having:
a fluid port having a flow tube;

a fluid outlet at a second end of the flow tube adapted to deliver fluid from the fluid source to a fluid pathway that provides fluid to a patient;
at least one sensor to characterize at least one attribute of the fluid from the fluid source; and
at least one pin in electrical communication with the at least one sensor; and

a second component comprising a base having:
at least one contact;
a controller in electrical communication with the at least one contact that generates at least one operation modification signal in response to at least one attribute matching at least one condition specified by at least one rule;
a transmitter for wirelessly transmitting the operation modification signal to at least one device, the operation modification signal, when received by the at least one device, causing the at least one device to modify at least one operating parameter; and
a cross-component electrical circuit,
wherein the flow sensor is mountable onto the base and said cross-component electrical circuit is a connection made by said contacts engaging said pins.

2. The system according to claim 1 , wherein the flow sensor further comprises end fittings adapted for securing the flow tube to the end fittings and a first piezo element and a second piezo element that are mounted to the end fittings.

3. The system according to claim 1 , wherein said flow tube is a stainless steel material.

4. The system according to claim 2 , wherein said first piezo element and said second piezo element are annular in shape and encircle the flow tube at each respective mounting point.

5. The system according to claim 1 , wherein said flow sensor is disposed of after use to generate one operation modification signal.

6. The system according to claim 5 , wherein the base is used with a different flow sensor.

7. The system according to claim 1 , wherein the flow sensor further comprises cantilevered wings adapted for securing the flow sensor to the base.

8. The system according to claim 1 , wherein the flow sensor further comprises a follower and said base further comprises a cam wherein said follower follows at least a portion of said cam when said flow sensor is mounted to the base.

9. The system according to claim 1 , wherein the flow sensor further comprises an opening and said base further comprises a protrusion wherein said opening is sized and shaped to engage said protrusion and said protrusion enters said opening when said flow sensor is mounted to said base.

10. The system according to claim 8 , wherein the flow sensor further comprises an opening and said base further comprises a protrusion wherein said opening is sized and shaped to engage said protrusion and said cam is adapted to move said at least one pin away from said protrusion while said protrusion enters said opening when said flow sensor is mounted to said base.

11. The system according to claim 10 , wherein the flow sensor further comprises at least one cantilevered wing having a tab adapted for securing the flow sensor to the base by engagement of said tab to at least one lip in the base.

12. The system according to claim 9 , wherein the flow sensor further comprises at least one cantilevered wing having a tab adapted for securing the flow sensor to the base by engagement of said tab to at least one lip in the base.

13. The system according to claim 12 , wherein the at least one cantilevered wing is deflectable in a direction to allow said tab to release from said at least one lip, thereby allowing said flow sensor to become de-mounted from said base.

14. The system according to claim 11 , wherein the at least one cantilevered wing is deflectable in a direction to allow said tab to release from said at least one lip thereby allowing said flow sensor to become de-mounted from said base.

15. The system according to claim 12 , wherein the at least one cantilevered wing is a pair of cantilevered wings.
