FLUID COLLECTION SYSTEMS SENSING AND NOTIFICATION AND RELATED METHODS

BACKGROUND

An individual may have limited or impaired mobility such that typical urination processes are challenging or impossible. For example, the individual may have surgery or a disability that impairs mobility. In another example, the individual may have restricted travel conditions such as those experience by pilots, drivers, and workers in hazardous areas. Additionally, fluid collection from the individual may be needed for monitoring purposes or clinical testing.

Bed pans and urinary catheters, such as a Foley catheter, may be used to address some of these circumstances. However, bed pans and urinary catheters have several problems associated with their use. For example, bed pans may be prone to discomfort, spills, and other hygiene issues. Urinary catheters be may be uncomfortable, painful, and may cause urinary tract infections.

Thus, users and manufacturers of fluid collection devices continue to seek new and improved devices, systems, and methods to collect bodily fluids.

FIG. 1A is a block diagram of a fluid collection system 100, according to an embodiment. The fluid collection system 100 includes a fluid (e.g., urine) collection device 102 configured to collect fluid discharged from a user. The fluid collection device 102 may include a male or female collection device. PCT International Application No. PCT/US2019/029616, for example, describes various embodiments of both male and female fluid collection devices, the disclosure of which is incorporated, in its entirety, by this reference. Moreover, the fluid collection device 102 may be interchangeable in the fluid collection system 100 between different types, varieties, and sizes of male or female fluid collection devices. The fluid collection device 102 may be configured to be positioned proximate or adjacent to a urethra of a user. Generally, the fluid collection device 102 may include a surface sized to be positioned proximate or adjacent to the urethra and configured to wick fluid or other fluids away from the user. Urine or other fluids may be wicked from the surface to a reservoir in the fluid collection device 102.

In some embodiments, the fluid collection system 100 may include a tube 104 that couples the fluid collection device 102 to a fluid collection container 106 and a vacuum device or pump 108. The tube 104 may include a flexible material such as plastic tubing (e.g., medical tubing). Such plastic tubing may include a thermoplastic elastomer, polyvinyl chloride, ethylene vinyl acetate, polytetrafluoroethylene, etc., tubing. In some embodiments, the tube 104 may include silicone or latex. In other embodiments, the tube 104 may include a reinforced tube having metal or other electrically conductive components therein. The fluid collection device 102, the container 106, and the pump 108 may be fluidly coupled to each other via one or more tubes 104. For example, fluid collection device 102 may be operably coupled to one or more of the fluid collection container 106 or the pump 108 via the tube 104. Fluid (e.g., urine or other bodily fluids) collected in the fluid collection device 102 may be removed from the fluid collection device 102 via the tube 104 coupled to the fluid collection device 102. A vacuum may be introduced into an interior chamber of the fluid collection device 102 via an inlet of the tube 104 responsive to suction (e.g., vacuum) force applied at an outlet of the tube 104.

The vacuum or suction force may be applied to the tube 104 by the pump 108 either directly or indirectly. The vacuum may be applied indirectly via the fluid collection container 106. For example, the outlet of the tube 104 may be connected to or disposed within the fluid collection container 106 and an additional tube 104 may extend from the fluid collection container 106 to the pump 108 or other suitable vacuum device. Accordingly, the pump 108 may apply a suction to the fluid collection device 102 via the fluid collection container 106. The vacuum may be applied directly via the pump 108. For example, the outlet of the tube 104 may be disposed within the pump 108. An additional tube 104 may extend from the pump 108 to a point outside of the fluid collection device 102, such as to the fluid collection container 106. In other embodiments, the pump 108 may be coupled to an exterior of the tube 104 to draw vacuum, such as a peristaltic pump. In such examples, the pump 108 or other vacuum device may be disposed between the fluid collection device 102 and the fluid collection container 106.

The pump 108 may include one or more of a manual vacuum pump, and electric vacuum pump, a diaphragm pump, a centrifugal pump, a displacement pump, a magnetically driven pump, a peristaltic pump, or any pump configured to produce a vacuum.

In some examples, the pump 108 may be powered by one or more of a power cord (e.g., connected to a power socket), one or more batteries, or even manual power (e.g., a hand operated vacuum pump). In some examples, the pump 108 may be sized and shaped to fit outside of, on, or within the fluid collection device 102. For example, the pump 108 may include one or more miniaturized pumps or one or more micro pumps.

The fluid collection container 106 may be sized and shaped to retain a fluid therein. The fluid collection container 106 may include a bag (e.g., drainage bag), a bottle or cup (e.g., collection jar), or any other enclosed container for storing bodily fluid(s) such as urine. In some embodiments, the fluid collection container 106 may include a generally rigid exterior housing an interior portion configured to contain the fluid. In some examples, the tube 104 may extend from the fluid collection device 102 and attach to the fluid collection container 106 at a first point therein. An additional tube 104 may couple to the fluid collection container 106 at a second point therein and may extend and attach to the pump 108. Accordingly, the pump 108 may be configured to pull an at least partial vacuum to draw the fluid from the fluid collection device 102 through the tube 104 into the fluid collection container 106. Fluid, such as urine, may be drained from the fluid collection device 102 and into the fluid collection container 106 via the pump 108.

For example, the computing device may indicate a net fluid loss of a user by determining the difference between the volume of fluid in the interior portion 132 as indicated by the volume sensor 128 and the fluid intake. As another example, based on data from the volume sensor 128, the controller 112 may wirelessly transmit an alert to the smartphone 142 of a caregiver that the interior portion 132 of the fluid collection container 106 is at a predetermined distance (such as about 1 inch) from the volume sensor 128 and/or the exterior housing 130 and emptying of the fluid collection container 106 is recommended. In some embodiments, the controller 112 may wirelessly transmit alerts and selected frequencies, such as selected time and/or volume intervals. In some embodiments, the computing device 114 may be configured to provide the at least one of the property or status of the fluid collection system 100 in real-time as communicated by the controller 112. The controller 112 may wirelessly transmit to the computing device 114 a property or status of the fluid collection system 100 or an alert to the electronic device of the user or the caregiver when a battery powering at least one of the controller 112, the module 140, or the pump 108 is low. The controller 112 may wirelessly transmit an alert to the electronic device of the user or the caregiver when cleaning or replacement of the fluid collection device 102 or other component may be due. In some embodiments, the controller 112 may issue an alarm and/or alert to the user or caregiver. The alert may include a light, a sound, or a message on the module 140 or smartphone 142 display 156. In an embodiment, the display 156 may provide at least the current status of the battery 118, the fill level of the fluid collection container 106, an input from the user or caregiver to include the volume of fluid consumed by the user, the time since the last replacement or cleaning of the fluid collection device 102, and the time since the least cleaning or replacement of the fluid collection container 106. In an embodiment, the computing device 114 may include a programmable timer 158. For example, the timer 158 may include an input from the user or caregiver to replace a component of the fluid collection system 100, empty the fluid collection container 106, or start or stop the pump 108. While an example computing device 114 is shown in FIGS. 4A-4B, the components illustrated in FIGS. 4A-4B are not intended to be limiting of the controller 112 or computing device 114.
