[0014] FIG. 3 is a flow diagram of a method for collecting urine, according to an embodiment. DETAILED DESCRIPTION

[0015] Embodiments disclosed herein are related to urine collection containers and systems including liner assemblies, and related methods. The devices and systems disclosed herein are configured to collect fluids from an individual. The fluids collected by the fluid collection devices may include at least one of urine, vaginal discharge, penile discharge, reproductive fluids, blood, sweat, or other bodily fluids.

[0016] In conventional urine collection systems, the urine is collected in a urine collection container that can then be emptied and washed. Emptying and washing the urine collection container after every use can be an unpleasant, tedious, time consuming, and frustrating chore for the user and/or a caregiver.

[0017] To improve conventional urine collection systems, liner assemblies described herein are positioned or positionable in the urine collection container of a urine collection system. In some embodiments, the liner assembly may be inserted into the canister to make removal of the urine much simpler and easier to perform, thereby minimizing the inconvenience of cleaning the system and also minimizing odors common to conventional urine collection systems. The liner assembly may instead prevent the urine from contacting the interior surfaces of the urine collection container and the liner may be disposable in some embodiments.

[0018] FIG. 1A is a block diagram of a fluid collection system 10, according to an embodiment. The urine collection system 10 may be included in embodiments of fluid collection systems described herein. The system 10 includes a urine collection device 12 (e.g., any of the urine collection devices disclosed herein), a urine collection container 14, and a pump 16 (or vacuum source). The urine collection device 12, the urine collection container 14, and the pump 16 may be fluidly coupled to each other via one or more conduits 18. For example, fluid collection device 12 may be operably coupled to one or more of the urine collection container 14 or the pump 16 via the conduit 18. In some embodiments, the pump 16 may be secured directly to the urine collection container 14. Fluid (e.g., urine or other bodily fluids) collected in the fluid collection device 12 may be removed from the fluid collection device 12 via the conduit 18 secured to the fluid collection device 12. Suction force may be introduced into the chamber of the fluid collection device 12 via the inlet of the conduit 18 responsive to suction (e.g., vacuum) force applied at the outlet of the conduit 18.

[0019] The suction force may be applied to the outlet of the conduit 18 by the pump 16 either directly or indirectly. The suction force may be applied indirectly via the urine collection container 14. For example, the outlet of the conduit 18 may be disposed within or fluidly coupled to an interior region of the urine collection container 14 and an additional conduit 18 may extend from the urine collection container 14 to the pump 16. Accordingly, the pump 16 may apply suction to the fluid collection device 12 via the urine collection container 14. The suction force may be applied directly via the pump 16. For example, the outlet of the conduit 18 may be disposed within the pump 16. An additional conduit 18 may extend from the pump 16 to a point outside of the fluid collection device 12, such as to the urine collection container 14. In such examples, the pump 16 may be disposed between the fluid collection device 12 and the urine collection container 14.

[0020] The urine collection container 14 is sized and shaped to retain a fluid therein. The urine collection container 14 may include a bag (e.g., drainage bag), a bottle, a canister, or a cup (e.g., collection jar), or any other enclosed container for storing bodily fluid(s) such as urine. In some examples, the conduit 18 may extend from the fluid collection device 12 and attach to the urine collection container 14 at a first point therein. An additional conduit 18 may attach to the urine collection container 14 at a second point thereon and may extend and attach to the pump 16. Accordingly, a vacuum (e.g., suction) may be drawn through fluid collection device 12 via the urine collection container 14. Fluid, such as urine, may be drained from the fluid collection device 12 using the pump 16. [0021] The pump 16 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. The pump 16 may provide a vacuum or suction to remove fluid from the fluid collection device 12. In some examples, the pump 16 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 16 may be sized and shaped to fit outside of, on, or within the fluid collection device 12. For example, the pump 16 may include one or more miniaturized pumps or one or more micro pumps. The vacuum sources disclosed herein may include one or more of a switch, a button, a plug, a remote, or any other device suitable to activate the pump 16.

[0022] FIG. IB shows an example of a urine collection system 100, according to an embodiment. The urine collection system 100 may include a urine collection device 102, a first tube 104 in fluid communication with an interior region of the urine collection device 102, a urine collection container 106, and a pump 108. In some embodiments, the urine collection container 106 may include a rectangular shape. The rectangular shape may make the urine collection system 100 more portable. The rectangular shape may make the urine collection container 106 easier to drain and/or clean, in some embodiments. The urine collection system 100 may be made to be disposed in a carrying case or bag, such as a backpack. In some embodiments, the urine collection system 100 may be rectangular shaped.

[0023] The urine collection container 106 may include a liner assembly 110, in some embodiments. The liner assembly 110 may include a liner 112 and a lid 114 secured or securable to the canister 114. The liner 112 may include a top region and a bottom region, and may at least partially define an interior region in fluid communication with the internal region of the urine collection device 102 via the first tube 104. In some embodiments, the liner 112 may include the same shape as the urine collection container 106. In other words, an outer surface of the liner 112 may completely contact an inner surface of the urine collection container 106. In other embodiments, the liner 112 may include other shapes, where the liner 112 does not contact the inner surface of the urine collection container 106 completely. In some embodiments, the liner 112 may rest on a rim of the urine collection container 106 and not contact the inner surface of the urine collection container 106.

[0024] The use of liner 112 can reduce cleaning frequency of the urine collection container 106, odors, and also makes a reduced workload on the user of the urine collection system 100 and/or a caretaker. Cleanliness can be improved without affecting the design and/or operation of the permanent components of the urine collection system 100. In some embodiments, the liner 112 may be configured to be reusable. The urine can be drained into a waste receptacle and the liner may be cleaned and returned to the urine collection container 106. In other embodiments, the liner 112 may be configured to be removable and replaceable. For example, the liner 112 may be single-use. After the urine collection container 106 has been filled once, the liner 112 may be disposed of and a new liner 112 may be placed within the urine collection container 106. The liner 112 can be disposed of along with the urine, which reduces urine exposer to the user and/or caretaker.

[0025] In some embodiments, the liner 112 may be configured to be non-collapsible under a vacuum pressure suitable to draw urine from the urine collection device 102 through the first tube 104 and into the urine collection container 106. Thus, the liner may be configured to be non-collapsible under a vacuum pressure of up to about 300 mmHg. For example, the liner 112 may be non-collapsible under a vacuum pressure of about 30 mmHg to about 60 mmHg, about 60 mmHg to about 100 mmHg, about 100 mmHg to about 150 mmHg, about 150 mmHg to about 200 mmHg, about 200 mmHg to about 300 mmHg, greater than about 50 mmHg, greater than about 100 mmHg, greater than about 200 mmHg, greater than about 250 mmHg, less than about 300 mmHg, less than about 250 mmHg, less than about 200 mmHg, less than about 150 mmHg, less than about 100 mmHg, or less than about 50 mmHg.

[0026] In some embodiments, the liner 112 can include a durable material that can be economical to dispose of and/or recycle. In some embodiments, the liner 112 can include at least one of a durable polyethylene, a cardstock, or a cardboard. In some embodiments, the liner 112 can include a soft polyethylene material and/or composite. In other embodiments, the liner 112 can include a cardstock having a weight from about an equivalent of light weight paper to about an equivalent of extra-heavy weight paper. In some embodiments, the cardstock may include a weight from about 65 lb. cardstock to about 140 lb. cardstock.
