Some current urine monitoring systems use weight-based methodologies to determine urine volume and urine flow rate over time. A fluid collection container may be suspended from a weighing device and as urine is captured by the fluid collection container, the weight of the fluid collection container increases. The weighing device may be configured to determine the increase in the weight of the fluid collection container. However, most urine monitoring systems do not travel with a patient as the patient is moved through a hospital setting, requiring clinicians to suspend urine monitoring until a patient is stationed in one location. If a patient has to move frequently within the hospital (e.g., multiple surgeries), critical patient data may not be captured. It would be beneficial to the patient and the clinician to be able to monitor urine output during the patient's entire stay.

The system 100 generally includes urinary output monitoring device (device) 110 and a urine collection bag (bag) 140. During use, the device 110 is attached to a securing surface 150 and the bag 140 is suspended from the device body 110. The bag 140 is selectively attachable to and detachable from the device 110. The device 112 is generally configured for multi-use across multiple patients and the bag 140 is generally configured for single-use across a single patient. In some instances, multiple bags 140 may be used for the same patient. The bag 140 includes drainage tube 142 coupleable with a urinary catheter (not shown), where the drainage tube 142 defines a urine flow path from the urinary catheter to the bag 140. In some embodiments, the fluid collection bag 140 may be fixedly attached to or otherwise include the urinary catheter.
The device 110 includes a device body 112 that generally defines a frame for the device 110 and a load cell 160 coupled between a bag attachment member 114 and the device body 112. The bag attachment member 114 may take any form suitable to enable the attachment of the bag 140 thereto in a suspended fashion. For example, the bag attachment member 114 may include a bar as illustrated, a hook, a ring, or a knob. The device body 112 may be coupled to the securing surface 150. More specifically, the device body 112 may be detachably coupled to the securing surface 150. In some instances of use, a clinician may attach and detach the device body 112 to and from the securing surface multiple times. The securing surface 150 may be any convenient surface suitable for attaching the device 110 thereto, such as a bed rail, an IV pole, or a wall, for example.
The device 110 includes a console 162 communicatively coupled with a display 190 so that system information thereon may be depicted on the display 190, where the system information includes urine output information or data. The display 150 is wirelessly coupled with the console 162 and physically separated from the device 110. Exemplary wireless communication modalities can include WiFi, Bluetooth, Near Field Communications (NFC), cellular Global System for Mobile Communication (“GSM”), electromagnetic (EM), radio frequency (RF), combinations thereof, or the like. The display 190 may be part of any suitable computing device, such as a personal computer, a network computer, a laptop, a tablet, or a cell phone, for example. The display 190 may be coupled with the console 162 via a local area network or the internet. The display 190 includes a user interface 191 (e.g., a graphical user interface) so that the clinician may interact with or otherwise operate the device 110 via the display 190.
The system 100 may be generally configured to minimize clinician interaction with the device 110. In some instances, clinician interaction may be limited to attaching the device 210 to the securing surface 150, hanging the bag 140 on the bag attachment member 114, removing the bag 140 from the bag attachment member 114, and detaching the device 210 from the securing surface 150. Other clinician interaction with the system 100 may occur via the display 190, where the display 190 is separated from the device 210. As such, aside from physical interaction, the clinician interact with the system 100 via the display 190 from a convenient location, such as an office, for example.
The load cell 160 is generally configured to (i) measure or otherwise determine load hangingly applied to the bag attachment member 114 and (ii) provide electrical signals to the console 162 in accordance with the load. In some embodiments, the device 110 may include more than one load cell 160. For example, the device 110 may include a first load cell aligned parallel with a transverse axis 51 the device body 112 and a second load cell aligned parallel with a longitudinal axis 52 (perpendicular to the transverse axis 51) of the device body 112. So arranged, the first and second load cells may account for an orientation of the device body 112, where the transverse axis 51 is not vertical. For example, in the case where the transverse axis 51 is vertical, the load may be determined by the first load sensor and in the case where the transverse axis 51 is horizontal and the longitudinal axis 52 is vertical, the load may be determined by the second load sensor. Further, in the case where the transverse axis 51 is oriented between the vertical and horizontal directions, the load may be determined by a combination of the first and second load sensors.
In some embodiments, the device 110 may include one or more sensors 130 configured to determine the orientation of the device body 112 (or more specifically the load cell 160), such as a gyroscope or an accelerometer, for example. In such embodiments, the one or more sensors 130 may provide an electrical signal to the console 162 indicating the orientation of the device body 112.
In some embodiments, the attachments 122 may include only one attachment that couples to each of the attachment points 124. In some embodiments, the attachment system 120 may include one or more rails 126 longitudinally coupled to the back panel 118 of the device body 112. In some embodiments, the one or more rails 126 may define the longitudinal axis 52. The two or more contact points 124 may be coupled to the one or more rails 126. Each contact point 124 of the two or more contact points 124 may be configured to independently slide longitudinally along the rails 126, allowing the device 112 to couple to any type of securing surface 150. The two or more contact points 124 may be configured to prevent the device body 112 from rotating around the longitudinal axis 194. In some instances, unnecessary rotation around the longitudinal axis 194 may impact the ability of the load cell 160 to accurately determine load cell values. The attachments 122 may include any suitable attachment mechanisms, such as hooks (e.g., J hooks, L hooks or the like), clamps, (e.g., circle clamps, spring clamps, pipe clamps, marman clamps, G/C clamps, locking clamps), clips, suction cups or the like. Advantageously, the attachment system 120 enable the urinary output monitoring device 110 to be coupled to any number of securing surfaces 150, allowing the urinary output monitoring system 100 to be mobile during use while consistently determining load cell values and moving with the user without interrupting use.
In some embodiments, the plurality of logic modules may include a load cell receiving logic 170, a sensor receiving logic 172, a load cell value correlation logic 174, a sensor value correlation logic 176, a transmission logic 178, and a data store 180. In some embodiments, the load cell receiving logic 170 may be configured to receive one or more load cell values or electrical signals from the load cell 160. In some embodiments the sensor receiving logic 172 may be configured to receive one or more sensor values or electrical signals from the one or more sensors 130 configured to determine the orientation of the device 110. In some embodiments, the load cell value correlation logic 174 may be configured to correlate the one or more load cell values with a volume value and a time of day value. In some embodiments, the volume value may correspond to the volume of fluid within the fluid collection bag 140 and the time of day value may correspond to the time of day the load cell value was determined. In some embodiments, the load cell value correlation logic 174 may be configured to correlate the load cell value with the volume value and time of day value as a {load cell value, volume value, time of day value}. In some embodiments, the sensor value correlation logic 176 may be configured to correlate the one or more sensor values with a degree value. In some embodiments, the degree value corresponds to the degree the orientation of the device 110 is away from level (e.g.,)0°. In some embodiments, the transmission logic 178 may be configured to transmit one or more of the load cell values, the volume values, the time of day values, the sensor values, or the degree values to the computing device or the electronic medical record system. In some embodiments, the transmission logic 178 may be configured to transmit one or more of the load cell values, the volume values, the time of day values, the sensor values, or the degree values to the display 190 as soon as the console 162 determines of the values or according to a user defined schedule (e.g., every 5 minutes, when a user presses the sync button, or the like). In some embodiments, the data store 180 may be configured to store one or more of the load cell values, the volume values, the time of day values, the sensor values, or the degree values until the console 162 communicates the values to the computing device or electronic medical record system.
