Urine output collection and monitoring systems, devices, and methods
Disclosed herein are medical devices, systems, and methods for collecting urine output from a patient, generally including a urine receiving device and a collection container coupled with the urine receiving device. Collection devices described herein can automatically determine collected urine volume, and also automatically determine protein content, salt content and pH of the collected urine. Collection devices can automatically display different colors according to collected volumes of urine. Some devices can determine the volume of urine within a patient's bladder. Systems can include a bladder volume device and logic to facilitate communication with external entities. Some systems may also include a urine collection device. Urine receiving devices can include external catheters.
1 . A medical device for monitoring urine output from a patient, comprising:
a urine receiving device;

a first flexible wall having a urine contact surface and an outward facing surface; and
a rigid first container wall having an inward facing surface extending along the outward facing surface; and
a console coupled with the collection container, the console including logic stored in memory that, when executed by one or more processors, causes performance of operations including rendering information on a display pertaining to a volume of collected urine within the collection container.
2 . The medical device of claim 1 , wherein:
the collection container comprises a pH sensor coupled with the console,
the pH sensor is configured to provide a pH signal to the console in accordance with a pH of the collected urine, and
the operations include rendering information on the display in accordance with the pH of the collected urine.
3 . The medical device of claim 1 , wherein:
the collection container comprises a urine volume sensor coupled with the console,
the urine volume sensor is configured to provide a volume signal to the console in accordance with the volume of the collected urine within the collection container, and
the operations include rendering information on the display in accordance with the collected urine within the collection container.
4 . The medical device of claim 3 , wherein:
the urine volume sensor includes the first flexible wall and the rigid first container wall,
a portion of the first flexible wall is separated away from the rigid first container wall a first distance when a first volume of urine is disposed within the collection container,
the portion of the first flexible wall is separated away from the rigid first container wall a second distance when a second volume of urine is disposed within the collection container, and
the second distance is different than the first distance.
5 . The medical device of claim 4 , wherein the rigid first container wall is a vertical wall.
6 . The medical device of claim 4 , wherein:
the urine volume sensor comprises a capacitive sensor coupled with the rigid first container wall,
the capacitive sensor is configured to detect a capacitance of a space extending between the rigid first container wall and the first flexible wall,
the capacitive sensor detects a first capacitance when the first flexible wall is separated from the rigid first container wall the first distance, the capacitive sensor providing a first capacitance signal to the console in accordance with the first volume, and
the capacitive sensor detects a second capacitance when the first flexible wall is separated from the rigid first container wall the second distance, the capacitive sensor providing a second capacitance signal to the console in accordance with the second volume.
7 . The medical device of claim 6 , wherein:
the urine volume sensor includes a second flexible wall extending along an inside surface of a second container wall opposite the rigid first container wall,
a portion of the second flexible wall is separated away from the portion of the first flexible wall a first separation distance when the first volume of urine is disposed within the collection container, the urine disposed between the first flexible wall and the second flexible wall,
the portion of the second flexible wall is separated away from the portion of the first flexible wall a second separation distance when the second volume of urine is disposed within the collection container, and
the second separation distance is different from the first separation distance.
8 . The medical device of claim 7 , wherein:
the capacitive sensor is configured to detect a fluid capacitance of a space extending between the rigid first container wall and the second container wall,
the capacitive sensor detects a third capacitance when the second flexible wall is separated from the first flexible wall the first separation distance, the capacitive sensor providing a third capacitance signal to the console in accordance with the first volume, and
the capacitive sensor detects a fourth capacitance when the second flexible wall is separated from the first flexible wall the second separation distance, the capacitive sensor providing a fourth capacitance signal to the console in accordance with the second volume.
9 . The medical device of claim 1 , further including a support structure coupled with the urine receiving device, the support structure configured to facilitate hands-free use of the medical device.
10 . The medical device of claim 9 , wherein the support structure comprises a seat.
11 . The medical device of claim 9 , wherein the support structure is adjustable in height.
12 . The medical device of claim 1 , wherein the collection container is configured for attachment to a leg of the patient.
13 . The medical device of claim 1 , wherein the urine receiving device is an external female catheter configured for securement via female anatomy.
14 . The medical device of claim 1 , wherein the rigid first flexible wall and the first container wall extend from a top end to a bottom end of the collection container.
15 . The medical device of claim 7 , wherein the second container wall is disposed parallel with the rigid first container wall.
