Abstract

Claims (73)

1. A system for monitoring urine output (UO) of a patient, comprising:

a UO module configured for coupling with a collection container, the UO module comprising:

a frame configured for anchoring to a bed, wherein the frame includes:

a first frame member; and

a second frame member coupled with the first frame member;

a load cell coupled with the frame, the load cell configured to define an electrical signal in accordance with a force defined by a weight of the UO within the collection container,

wherein:

the collection container is configured to collect UO therewithin,

in use, the UO flows through a drainage tube extending between the patient and the collection container, and

the load cell is operatively coupled between the first frame member and

the second frame member; and

a console including logic stored in memory that, when executed by one or more processors, causes performance of operations that include:

receiving the electrical signal from the load cell,

converting the electrical signal into volumetric UO data, and

transmitting the volumetric UO data across a network to an external entity.

2. The system of claim 1 , further comprising the collection container.

3. The system of claim 2 , further including an identification device coupled with the collection container, the identification device including patient identification information, wherein the identification device is one of a barcode, a matrix code, or a radio-frequency identification (RFID) tag.

4. The system of claim 3 , wherein

the first frame member comprises one or more hooks configured to anchor the first frame member to one or more frame rails of the bed.

5. The system of claim 4 , wherein:

the second frame member includes a weight measurement arm configured to couple with the collection container, and

in use, the collection container hangs from the weight measurement arm.

6. The system of claim 4 , wherein:

the first frame member includes a drainage tube retention device coupled thereto, and

the drainage tube retention device is configured to secure a portion of the drainage tube to the first frame member to isolate movement of a proximal portion of the drainage tube from movement of a distal portion of the drainage tube.

7. The system of claim 4 , wherein:

the first frame member comprises a first horizontal shelf disposed at a bottom of the first frame member,

the second frame member comprises a second horizontal shelf disposed above the first horizontal shelf, and

the load cell is coupled between the first horizontal shelf and the second horizontal shelf.

8. The system of claim 5 , further comprising an intermediate coupling device configured to couple the collection container with the weight measurement arm, the intermediate coupling device configured to selectively couple with the weight measurement arm and decouple from the weight measurement arm.

9. The system of claim 8 , wherein the intermediate coupling device is configured to:

couple with the collection container, and

inhibit decoupling from the collection container.

10. The system of claim 8 , wherein the intermediate coupling device includes an S-hook comprising:

an upper hook opening configured to receive the weight measurement arm, and

a lower hook opening configured to receive a coupling loop of the collection container.

11. The system of claim 10 , wherein the S-hook further comprises a rotatable latching arm, and wherein the rotatable latching arm:

extends across the lower hook opening to define a closed position,

is rotatable away from the closed position toward the lower hook opening to provide access to the lower hook opening, and

is biased toward the closed position.

12. The system of claim 11 , wherein in use:

the coupling loop of the collection container exerts a force on the rotatable latching arm to rotate the rotatable latching arm away from the closed position allowing the lower hook opening to receive the coupling loop, and

the rotatable latching arm self-rotates back to the closed position, inhibiting removal of the coupling loop from the lower hook opening.

13. The system of claim 10 , wherein, in use, the identification device is attached to the S-hook.

14. The system of claim 13 , wherein the operations further include:

obtaining the patient identification information from the identification device, and

linking the volumetric UO data with the patient identification information.

15. A method of monitoring urine output (UO) of a patient, comprising:

coupling a UO collection container with a urinary catheter of the patient, via a drainage tube extending between the urinary catheter and the UO collection container;

coupling the UO collection container with a UO monitoring system, the UO monitoring system comprising a load cell configured to measure a weight of the UO within the UO collection container;

anchoring the UO monitoring system to a patient bed;

establishing a flow of urine from the patient to the UO collection container;

measuring the weight of the UO within the UO collection container;

converting the weight of the UO into volumetric UO data; and

transmitting the volumetric UO data across a network to an external entity,

wherein:

the UO monitoring system includes a first frame member and a second frame member,

the load cell is operatively coupled between the first frame member and the second frame member, and

the load cell is configured to measure a force between the first frame member and the second frame member.

16. The method of claim 15 , further comprising coupling an identification device with the UO collection container, wherein the identification device includes patient identification information.

17. The method of claim 16 , wherein anchoring the UO monitoring system to the patient bed comprises coupling one or more hooks of the first frame member of the UO monitoring system with one or more frame rails of the patient bed.

18. The method of claim 16 , wherein the second frame member of the UO monitoring system includes a weight measurement arm, the method further comprising hanging the UO collection container from the weight measurement arm.

19. The method of claim 16 , The method of claim 1 , wherein the first frame member further includes a drainage tube retention device configured to isolate movement of a distal portion of the drainage tube from movement of a proximal portion of the drainage tube, the method further comprising securing the drainage tube to the first frame member via the drainage tube retention device.

20. The method of claim 18 , further comprising coupling an intermediate coupling device of the UO monitoring system between the UO collection container and the weight measurement arm, the intermediate coupling device configured to inhibit decoupling of the intermediate coupling device from the UO collection container.

21. The method of claim 20 , wherein coupling the identification device with the UO collection container comprises attaching the identification device to the intermediate coupling device.

22. The method of claim 21 , further comprising:

obtaining the patient identification information from the identification device, and

linking the volumetric UO data with the patient identification information.

23. The system of claim 1 , wherein:

the first frame member is attached to the second frame member via one or more resilient coupling components, and

the one or more resilient coupling components:

constrain horizontal displacement of the second frame member with respect to the first frame member, and

allow vertical displacement of the second frame member with respect to the first frame member.
