Abstract

A system includes a flow sensor contained within a flow sensor housing, a base, and a seal. The base houses a controller that generates at least one operation modification signal, and the flow sensor is separable from and mountable onto the base. A bottom surface of the flow sensor housing includes the seal. The seal forms a liquid-tight engagement between the flow sensor housing and the base when the flow sensor is mounted onto the base.

First claim

What is claimed is:

1. A system comprising:
a flow sensor contained within a flow sensor housing;
a base that houses:
a controller that generates at least one operation modification signal, wherein the flow sensor is separable from and mountable onto the base;

a seal, wherein a bottom surface of the flow sensor housing includes the seal, wherein the seal forms a liquid-tight engagement between said flow sensor housing and said base when said flow sensor is mounted onto the base; and
a vault on the bottom surface of the flow sensor housing, wherein the vault includes a depending skirt surrounding the seal.

2. The system according to claim 1 , wherein the flow sensor includes at least one sensor to characterize at least one attribute of a fluid from a fluid source and at least one pin in electrical communication with the at least one sensor, wherein the seal surrounds the at least one pin, and wherein said at least one sensor is in electrical communication with said controller via a connection between the flow sensor and the base when the flow sensor is mounted onto the base.

3. The system according to claim 2 , wherein the controller generates the at least one operation modification signal in response to the at least one attribute matching at least one condition specified by at least one rule,
wherein the flow sensor includes:
a fluid port having a flow tube;
a fluid inlet at a first end of the flow tube adapted to couple to an outlet of the fluid source;
a fluid outlet at a second end of the flow tube adapted to deliver the fluid from the fluid source to a fluid pathway that provides the fluid to a patient; and
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,

wherein the base further houses:
a transmitter for 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
at least one contact, wherein the controller is in electrical communication with the at least one contact, wherein the connection between the flow sensor and the base includes a cross-component electrical circuit made by said contacts engaging said pins, and wherein the transmitter wireles sly transmits the operation modification signal to at least one device.

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

5. The system according to claim 3 , wherein said first piezo element and said second piezo element are annular in shape and encircle the flow tube at each respective mounting point.

6. The system according to claim 3 , wherein said flow sensor is disposed of after use to generate one operation modification signal.

7. The system according to claim 6 , wherein the base is used with a different flow sensor, wherein the base includes at least one contact, and wherein the controller is in electrical communication with the at least one contact.

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

9. 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.

10. The system according to claim 9 , 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 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.

13. The system according to claim 11 , wherein the at least one cantilevered wing is a pair of cantilevered wings.

14. The system according to claim 11 , wherein the at least one cantilevered wing is a pair of cantilevered wings and each respective wing is arranged opposite each other and said opening is spaced away from said wings and said opening has a center position which bisects a distance between said cantilevered wings.

15. 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.

16. The system according to claim 15 , 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.

17. The system according to claim 16 , 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.

18. The system according to claim 16 , wherein the at least one cantilevered wing is a pair of cantilevered wings.

19. The system according to claim 16 , wherein the at least one cantilevered wing is a pair of cantilevered wings and each respective wing is arranged opposite each other and said opening is spaced away from said wings and said opening has a center position which bisects a distance between said cantilevered wings and the follower is a pair of followers and each respective follower is arranged opposite each other on said flow sensor.

20. The system according to claim 1 , wherein the flow sensor further comprises cantilevered wings having a tab adapted for securing the flow sensor to the base by engagement of said tab to a lip in the base.
