Abstract

A fluid monitoring assembly includes a conduit having a wall defining a lumen for carrying fluid. A sensor mount is integrally formed with the wall of the conduit and extends generally transverse with respect to a longitudinal axis of the conduit, the sensor mount including an aperture defining an inner surface extending to the lumen. The assembly includes a sensor configured to be removably secured within the sensor mount, the sensor having an elongate body terminating at one end thereof in a sensing portion, the elongate body having a male projection on a portion thereof and configured to rest within the inner surface of the sensor mount. The assembly further includes a housing having first and second portions connected to one another, the housing defining an interior portion configured to encapsulate the conduit, at least a portion of the elongate body of the sensor, and the sensor mount.

Claims

1. A fluid monitoring assembly comprising:

a segment of replaceable, flexible conduit comprising a wall defining a lumen through which the fluid passes;

a sensor mount integrally formed with the wall of the segment of replaceable, flexible conduit and extending generally transverse with respect to a longitudinal axis of the segment of replaceable, flexible conduit, the sensor mount including an aperture defining an inner surface extending through the sensor mount to the lumen of the segment of replaceable, flexible conduit;

a sensor configured to be removably secured within the sensor mount, the sensor having an elongate body terminating at one end thereof in a sensing portion, the elongate body having a flange on a portion thereof that rests on or within the sensor mount when secured within the sensor mount; and

a housing having first and second portions connected to one another at a hinge, the housing defining an interior portion configured to encapsulate the segment of replaceable, flexible conduit, the sensor mount, and the elongate body of the sensor.

2. The fluid monitoring assembly of claim 1, the housing further comprising at least one fastener configured to secure the first and second portions of the housing in a closed state.

3. The fluid monitoring assembly of claim 1, wherein the housing comprises metal or polymer.

4. The fluid monitoring assembly of claim 1, wherein the flange rests on an upper surface of the sensor mount.

5. The fluid monitoring assembly of claim 1, wherein the flange rests on a recessed seat disposed on the sensor mount.

6. The fluid monitoring assembly of claim 1, wherein the sensor comprises one of a pressure sensor, a conductivity sensor, a temperature sensor, and a pH sensor.

7. The fluid monitoring assembly of claim 1, wherein the segment of replaceable, flexible conduit comprises at least one of silicone, thermoplastic elastomer, or thermoplastic rubber.

8. The fluid monitoring assembly of claim 1, wherein the sensor comprises a memory configured to store calibration data therein.

9. The fluid monitoring assembly of claim 1, wherein the housing comprises at least one pinch valve mounted thereon.

10. The fluid monitoring assembly of claim 1, wherein the elongate body comprises a barbed end.

11. A fluid monitoring assembly comprising:

a segment of replaceable, flexible conduit comprising a wall defining a lumen through which the fluid passes;

a sensor mount integrally formed with the wall of the segment of replaceable, flexible conduit and extending generally transverse with respect to a longitudinal axis of the segment of replaceable, flexible conduit, the sensor mount including an aperture defining an inner surface extending through the sensor mount to the lumen of the segment of replaceable, flexible conduit;

a sensor configured to be removably secured within the sensor mount, the sensor having an elongate body terminating at one end thereof in a sensing portion;

an insert disposed on the elongate body of the sensor, the insert comprising a flange on a portion thereof that rests on or within the sensor mount when secured within the sensor mount; and

a housing having first and second portions connected to one another at a hinge, the housing defining an interior portion configured to encapsulate the segment of replaceable, flexible conduit, the sensor mount, and at least a portion of the insert.

12. The fluid monitoring assembly of claim 11, the housing further comprising at least one fastener configured to secure the first and second portions of the housing in a closed state.

13. The fluid monitoring assembly of claim 11, wherein the housing comprises metal or polymer.

14. The fluid monitoring assembly of claim 11, wherein the flange rests on an upper surface of the sensor mount.

15. The fluid monitoring assembly of claim 11, wherein the flange rests on a recessed seat disposed on the sensor mount.

16. The fluid monitoring assembly of claim 11, wherein the sensor comprises one of a pressure sensor, a conductivity sensor, a temperature sensor, and a pH sensor.

17. The fluid monitoring assembly of claim 11, wherein the segment of replaceable, flexible conduit comprises at least one of silicone, thermoplastic elastomer, or thermoplastic rubber.

18. The fluid monitoring assembly of claim 11, wherein the sensor comprises a memory configured to store calibration data therein.

19. The fluid monitoring assembly of claim 11, wherein the housing comprises at least one pinch valve mounted thereon.

20. The fluid monitoring assembly of claim 11, wherein the elongate body comprises a barbed end.
