Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to U.S. Provisional Patent Application No. 63 / 159,142, filed March 10, 2021, the disclosure of which is incorporated by reference in its entirety herein. [Background technology]

[0002] An individual may have limited or impaired mobility, making the typical process of urination difficult or impossible. For example, an individual may have undergone surgery or have a disability that impairs mobility. In another example, an individual may have restricted mobility conditions, such as those experienced by pilots, drivers, and workers in hazardous areas. Additionally, collection of bodily fluids from an individual may be necessary for monitoring purposes or clinical testing.

[0003] Bedpans and urinary catheters, such as Foley catheters, may be used to address some of these situations (see, for example, U.S. Patent No. 5,393,633). However, bedpans and urinary catheters have several problems associated with their use. For example, bedpans can be prone to discomfort, spillage, and other hygiene issues. Urinary catheters can be uncomfortable, painful, and can lead to urinary tract infections.

[0004] Thus, users and manufacturers of fluid collection devices continue to seek new and improved devices, systems, and methods for sampling bodily fluids. [Prior art documents] [Patent documents]

[0011] The embodiments disclosed herein relate to a fluid collection system including a means for sensing at least one of a property or condition of the fluid collection system, and a method of using the same. The devices and systems disclosed herein are configured to collect fluid from an individual and include at least one sensor. The fluid collected by the fluid collection device may include at least one of urine, vaginal secretions, penile secretions, reproductive fluids, blood, sweat, wound secretions, interstitial fluid, cerebrospinal fluid, or other bodily fluids. The embodiments of the fluid collection system disclosed herein may include a means for sensing at least one of a property or condition of the fluid collection system and a controller operably coupled to the sensing means, the controller configured to inform a computing device of at least one of the property or condition of the fluid collection system. The at least one property of the fluid collection system may relate at least to a volume of fluid exiting the fluid collection device and / or a volume of fluid entering a fluid collection container.

[0012] In some embodiments, the characteristic may include at least one of a volume, mass, or velocity of fluid passing through or in proximity to a tube in fluid communication with the fluid collection device. For example, the sensing means may include a flow meter connected to the tube, the flow meter configured to measure a volumetric flow rate of the fluid. In some embodiments, the flow characteristic may include a flow rate of the fluid over a predetermined period of time. At least one of the sensing means may include a sensor disposed within an interior portion of the fluid collection container, where the sensor is configured to detect a characteristic related to the volume or mass of the fluid in the fluid collection container.

[0013] The fluid collection system may also include a controller operably coupled to the sensing means, the controller configured to communicate at least one of the characteristics or conditions of the fluid collection system to a computing device. By having the controller sense at least one of the characteristics or conditions of the fluid collection system and communicate at least one of the characteristics or conditions of the fluid collection system to a computing device, more accurate volume, volumetric flow rate, and fluid collection system information and / or status may be determined, collected, and / or utilized in real time. Providing greater accuracy and convenience to the user and / or caregiver may result in a cleaner and more hygienic fluid collection system and optimized care.

[0014] In some examples, the computing device or system that receives at least one of the detected flow characteristics or volume of the fluid may include a module mounted on an arm of a wheelchair or a smartphone. As described in more detail herein, the computing device may include a programmable timer, an alert or alarm, or a display configured to display at least one characteristic of the fluid or a status of the fluid collection system. In some examples, the computing device may be wirelessly connected to the controller.

[0015] FIG. 1A is a block diagram of a fluid collection system 100, according to one 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. For example, PCT International Application No. PCT / US2019 / 029616 describes various embodiments of both male and female fluid collection devices, the disclosure of which is incorporated by this reference in its entirety. Furthermore, the fluid collection device 102 may be interchangeable between different types, variations, and sizes of male or female fluid collection devices in the fluid collection system 100. The fluid collection device 102 may be configured to be placed in close proximity to or adjacent to the urethra of a user. In general, the fluid collection device 102 may include a surface sized to be placed in close proximity to or adjacent to the urethra and configured to wick fluid or other fluids from a user. Urine or other fluids may be wicked from the surface to a reservoir within the fluid collection device 102.

[0016] In some embodiments, the fluid collection system 100 may include tubing 104 connecting the fluid collection device 102 to a fluid collection container 106 and a vacuum device or pump 108. The tubing 104 may include a flexible material such as plastic tubing (e.g., medical tubing). Such plastic tubing may include thermoplastic elastomer, polyvinyl chloride, ethylene vinyl acetate, polytetrafluoroethylene, and the like tubing. In some embodiments, the tubing 104 may include silicone or latex. In another embodiment, the tubing 104 may include a reinforced tube having a metal or other conductive component therein. The fluid collection device 102, container 106, and pump 108 may be fluidly connected to one another via one or more of the tubing 104. For example, the fluid collection device 102 may be operably connected to one or more of the fluid collection container 106 or pump 108 via the tubing 104. Fluid (e.g., urine or other bodily fluids) collected within the fluid collection device 102 may be removed from the fluid collection device 102 via a tube 104 connected to the fluid collection device 102. A vacuum may be drawn into the interior chamber of the fluid collection device 102 via an inlet of the tube 104 in response to a suction (e.g., vacuum) force supplied to an outlet of the tube 104.

[0017] The vacuum or suction force may be provided to the tube 104 directly or indirectly by the pump 108. The vacuum may be provided indirectly via the fluid collection reservoir 106. For example, the outlet of the tube 104 may be connected to or disposed within the fluid collection reservoir 106, and an additional tube 104 may extend from the fluid collection reservoir 106 to the pump 108, or to another suitable vacuum device. Thus, the pump 108 may provide suction to the fluid collection device 102 via the fluid collection reservoir 106. The vacuum may be provided directly via the pump 108. For example, the outlet of the tube 104 may be disposed within the pump 108. The additional tube 104 may extend from the pump 108 to a point outside the fluid collection device 102, for example to the fluid collection reservoir 106. In another embodiment, the pump 108, such as a peristaltic pump, may be connected to the exterior of the tube 104 to draw a vacuum. In such an example, the pump 108 or other vacuum device may be disposed between the fluid collection device 102 and the fluid collection container 106 .

[0018] The pump 108 may include one or more of a manual vacuum pump, an electric vacuum pump, a diaphragm pump, a centrifugal pump, a positive displacement pump, a magnetic drive pump, a peristaltic pump, or any pump configured to generate a vacuum. The pump 108 may provide a vacuum or suction to remove fluid from the fluid collection device 102 that may be drained by a user. In some examples, the pump 108 may be powered by one or more power cords (e.g., connected to a power socket), one or more batteries, or even a manual power source (e.g., a manual vacuum pump). In some examples, the pump 108 may be sized and shaped to fit outside, on, or inside the fluid collection device 102. For example, the pump 108 may include one or more miniature pumps or one or more micro pumps.

[0019] The fluid collection container 106 may be sized and shaped to hold fluid therein. The fluid collection container 106 may include a bag (e.g., a drainage bag), a bottle or cup (e.g., a 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 outer housing and an inner portion configured to contain fluid. In some examples, the tube 104 may extend from the fluid collection device 102 and be attached to the fluid collection container 106 at a first point therein. An additional tube 104 may connect to the fluid collection container 106 at a second point therein and may extend and be attached to the pump 108. The pump 108 may thus be configured to draw at least a partial vacuum to draw fluid from the fluid collection device 102, through the tube 104, and into the fluid collection container 106. Fluid, such as urine, may be expelled from the fluid collection device 102 into the fluid collection container 106 via the pump 108.

[0020] The fluid collection system 100 may include a means for sensing 110 of at least one of the characteristics or conditions of the fluid collection system 100. The means for sensing 110 may include at least one sensor, flow meter, and / or device to obtain a state of the fluid collection system 100 or a characteristic of a fluid within the fluid collection system 100. In some embodiments, the means for sensing 110 may include a flow meter 116 connected to the tube 104 and configured to detect a vacuum condition within the tube 104 or measure a volumetric flow rate of a fluid. In some embodiments, a metal or other conductive component within the tube 104 may function as an electromagnetic flow meter (not shown). The electromagnetic flow meter may include a change in conductance or capacitance as a means for sensing flow. The fluid collection system 100 may also include a controller 112 operably coupled to the flow meter such that the flow meter 116 coupled to the controller is the means for sensing 110 and configured to inform the computing device 114 of at least one of the characteristics or conditions of the fluid collection system 100.

[0021] The flow meter 116 may also include a controller 112 operably coupled to the flow meter 116 or may be operably coupled to the controller 112, where the controller is configured to communicate at least one of a flow characteristic or a state of the fluid to the computing device 114. In some embodiments, the controller 112 may be separate from the flow meter 116 or may be external to the flow meter 116. For example, the flow meter 116 may be configured to wirelessly communicate data to the computing device 114 via BLUETOOTH or WI-FI, where the data includes at least one of a detected flow characteristic or a volume of the fluid discharged from the user into the fluid collection container 106. In some embodiments, the controller 112 may be integrated with the computing device 114. In some embodiments, the flow meter 116 may be configured to wirelessly communicate volumetric flow data to the computing device 114 at predetermined intervals or whenever a fluid flow is detected. The computing device 114 may include various computing devices configured to wirelessly communicate with the flow meter 116. For example, the computing device 114 may include a module coupled to a wheelchair or bed, a smartphone, a smart wearable (e.g., a wrist device), a tablet computer, a desktop computer, or a medical computing device in a hospital or health care office.

[0022] In some embodiments, the flow meter 116 may be configured to wirelessly communicate the fluid flow characteristics to the controller 112, which may then wirelessly communicate the volumetric flow rate to the computing device 114, which may include a software application configured to record data including the amount of fluid received or consumed by the user, the fluid flow rate, display the fluid flow rate and / or volume the user has expelled, and / or determine and display trends and totals related to the fluid flow rate and / or volume the user has expelled. The computing device 114 may be located on the user in a hospital room, in the user's home, coupled to a wheelchair, or a combination thereof. In some examples, the pump 108, the sensing means 110, the controller 112, and the computing device 114 may be powered by one or more batteries 118. Further details regarding schematics, power sources, and wireless communications of the controller 112 and the computing device 114 are provided below with reference to FIG. 3.

[0023] 1B-1E, in some embodiments, the sensing means 110 includes a flow meter 116 configured to detect a flow characteristic of the fluid related at least to a volume of fluid drawn from the fluid collection device 102 and passing through the tube 104 before the fluid enters the fluid collection container 106. In some embodiments, the flow meter 116 may be connected to the tube 104 between the fluid collection device 102 and the fluid collection container 106, such that a first portion of the tube 104 extends between the fluid collection device 102 and the flow meter 116 and a second portion of the tube 104 extends between the flow meter 116 and the fluid collection container 106. In some embodiments, the flow meter 116 may be coupled to the fluid collection device 102. In some embodiments, the flow meter 116 may be coupled to the fluid collection container 106. The flow meter 116 may include any suitable flow meter configured to detect flow characteristics of a fluid, which may be used to determine the presence of a vacuum or a volume of fluid passing through or within a predetermined vicinity of the flow meter 116.

[0024] In some embodiments, the flow meter 116 may include an in-line ball-type aiming flow indicator disposed within the tube 104. The ball-type aiming flow indicator may include a float 120 of a ball or other suitable shape. In some embodiments, the float 120 may be visible when a vacuum is applied, but may not be visible when no vacuum is present. In some embodiments, the flow meter 116 may include a visible region 122 and a non-visible region 124. The visible region 122 may include a transparent observation window. The observation window may include markings to indicate the flow rate within the flow meter 116 or the tube 104. The non-visible region 124 may hide the float 120 when no vacuum is present. The float 120 within the non-visible region 124 may indicate at least one condition of the fluid collection system 100. In some embodiments, the pump 108 may be off or inoperable when the float 120 is within the non-visible region 124. In another embodiment, the tube 104 may be clogged, kinked, or cut. In yet another embodiment, the fluid collection container 106 may be full or overflowing, or the fluid collection system 100 may have a leak or other failed component. In some embodiments, the float 120 may be supported by the flow of fluid within the tube 104. The float 120 may be ball and / or grooved to help the float 120 remain in the center of the fluid flow.

[0025] In some embodiments, the float 120 may be coupled to a spring 126 or other suitable resilient member or mechanism. The flow meter 116 may include a spring 126 and a piston (e.g., ball float 120) flow meter disposed within the first tube 104, where the spring 126 is calibrated to hold the piston so that it is visible when a vacuum is applied and invisible when no vacuum is present. As described above, the flow meter 116 may include a visible region 122 and a non-visible region 124, and the piston may operate in a manner similar to the float 120 described above.

[0026] In some embodiments, the flow characteristics detected by the flow meter 116 may include at least one of a volume, a mass, or a velocity of the fluid passing through or near the flow meter 116. The flow meter 116 may include a positive displacement flow meter configured to directly measure the actual volume of the fluid passing through the flow meter 116. In some embodiments, the flow meter 116 is configured to detect a mass or velocity of the fluid passing through or near the flow meter 116, which may be converted (by at least one of the flow meter 116 or the computing device) to a volume or flow rate. The flow meter 116 may detect the duration during which the fluid passes through or is within a predetermined vicinity of the flow meter 116. The flow meter 116 or other computing device may then calculate the volume of the fluid that has passed through the flow meter 116 based on the known cross-sectional area or volume of the tube 104 or the flow meter 116.

[0027] In some embodiments, the flow meter 116 may mechanically or ultrasonically detect flow characteristics of the fluid passing between the fluid collection device 102 and the fluid collection vessel 106. For example, at least a portion of the flow meter 116 may be in-line with the tube 104 and effective to enable the flow meter 116 to mechanically detect flow characteristics of the fluid through the tube 104. In some embodiments, the flow meter 116 may be integrated into the tube 104. In some embodiments, at least a portion of the flow meter 116 extends into the tube 104 and effective to enable the flow meter 116 to mechanically detect flow characteristics of the fluid through the tube 104. The flow meter 116 may include at least one of a birotor, a disk, a piston, a propeller, a paddle wheel, and / or a rotameter. The flow meter 116 may include a laminar flow meter or a venturi flow meter. In some embodiments, the flow meter 116 may be removably or permanently secured to the outside of the tube 104 and may ultrasonically (i.e., via the Doppler effect) or electromagnetically detect the flow characteristics of the fluid passing through the tube 104.

[0028] 2A, the sensing means 110 of the fluid collection system 100 may also include a volume sensor 128. The volume sensor 128 may be coupled to the fluid collection container 106 and configured to detect at least a characteristic related to a volume of fluid within an interior portion of the fluid collection container 106. In some embodiments, the fluid collection container 106 may include an exterior housing 130 and an interior portion 132. The interior portion 132 may be configured to contain fluid. In some embodiments, the volume sensor 128 may be disposed between the exterior housing 130 and the interior portion 132. In another embodiment, the volume sensor 128 may be located or disposed at an inlet (either internal or external) of the fluid collection container 106 for the tube 104. The volume sensor 128 may be disposed along and / or within the tube 104, according to one embodiment.

[0029] Similar to the flow meter 116 described above, the volume sensor 128 may also include a controller 112 operably coupled to the volume sensor 128, and configured to inform the computing device 114 of the volume of fluid in the fluid collection container 106. The controller 112 may be configured such that the volume sensor 128 and the controller are a sensing means 110 that informs the computing device 114 of at least one of the characteristics or conditions of the fluid collection system 100. In some embodiments, the controller 112 may be separate from the volume sensor 128 and / or the fluid collection container 106, or may be external to the volume sensor 128 and / or the fluid collection container 106. The controller 112 may be internal to the computing device 114 or may be coupled to the computing device 114. The computing device 114 may be the same computing device 114 described above and / or may include a variety of computing devices configured to wirelessly communicate with the volume sensor 128. For example, the computing device 114 may include a module coupled to a wheelchair or a bed, and / or a smartphone.

[0030] 2B, in some embodiments, the external housing 130 may be opaque or transparent according to different embodiments and may include a generally rectangular front or back profile. In some embodiments, the external housing may include at least one of a handle or spout 134. Fluid collected in the internal portion 132 may be emptied through the spout 134 after removing the cap or cover 136. The external housing 130 may be reusable and dishwasher safe and may include a generally rigid material, such as polycarbonate, plastic, rubber, metal, glass, combinations thereof, or any other suitable material. In some embodiments, the internal portion 132 may be expandable. The internal portion 132 may include a bellows shape and expand when filled with fluid. In some embodiments, the internal portion 132 may be an expandable bladder. For example, the internal portion 132 may be approximately flat when empty, but may expand when urine or other fluids are poured into the internal portion 132. In another embodiment, the internal portion 132 may include a material that expands when wet. In some embodiments, the interior portion 132 may be constructed of polycarbonate, plastic, rubber, metal, latex. In other embodiments, the interior portion may be hygroscopic, for example, paper, cotton, wood, nylon, superabsorbent polymers (SAP) such as sodium polyacrylate, polyacrylamide, or other suitable materials. In some embodiments, the volume sensor 128 may be configured to activate when the interior portion 132 expands to a predetermined volume. In some embodiments, the volume sensor 128 may include a switch located on an inner surface of the external housing 130 that activates when the interior portion 132 expands to compress the switch between the interior portion 132 and the external housing 130. In other embodiments, the volume sensor 128 may be located on a sidewall of the external housing 130, an outer surface of the interior portion 132, or any suitable location between the external housing 130 and the interior portion 132.

[0031] 2C, in some embodiments, the internal portion 132 is substantially rigid and the volume sensor 128 may include at least one of a pressure sensor, a capacitance sensor, or an optical sensor. In some embodiments, the pressure sensor may be configured to operate an electrical contact when a predetermined fluid mass is reached. The pressure sensor may close an electrical contact or communicate with the controller 112 regarding a pressure increase caused by the internal portion 132 filling with fluid. The capacitance sensor may include a proximity sensor or a non-contact sensor that may be configured to utilize the electrical properties of capacitance and a change in capacitance based on a change in the electric field around the active surface of the capacitance sensor. In some embodiments, as the internal portion 132 approaches the external housing 130, a metal plate of the sensing surface of the capacitance sensor may be electrically connected to an internal oscillator circuit and the surface of the internal portion being sensed may act as a second plate of a capacitor and may be configured to operate an electrical contact and / or communicate with the controller 112 when a predetermined distance is reached between the surface of the internal portion 132 and the external housing 130. In an optical sensor, a light beam may be converted into an electronic signal. In one embodiment, the optical sensor may be coupled to an electrical switch that activates in response to a change in the signal in the optical sensor and / or sends a signal to the controller 112 when the surface of the internal portion 132 approaches a predetermined distance from the external housing 130.

[0032] In some embodiments, the means for sensing 110 may include a system integrity sensor 138. The system integrity sensor 138 may be configured to detect when the fluid collection device 102 is disconnected from the fluid collection container 106. The integrity sensor 138 may be coupled to the fluid collection device 102, the pump 108 shown in FIG. 2B, the flow meter 116, the external housing 130 of the fluid collection container 106, or any suitable location or configuration to determine whether a component is disconnected and / or malfunctioning. In some embodiments, the system integrity sensor 138 may include a simple contact switch between components, for example, between the tube 104 and the fluid collection container 106, as shown in FIG. 2C.

[0033] 3 is a schematic diagram of a controller 112 that may be integrated into any of the sensing means 110 described above or the computing device 114 described herein, according to some embodiments. The controller 112 may be configured to communicate with any sensing means 110, such as via a wired or wireless connection. In some embodiments, the sensing means 110 may include the controller 112. In one embodiment, the controller 112 may include a printed circuit board (PCB) with an erasable programmable read-only memory (EPROM) for storage of at least the data collected by the sensing means 110. For example, the controller 112 may be configured to calculate the level or volume of fluid in the fluid collection container 106, or the volumetric flow rate or presence of fluid in the first tube 104. The controller 112 may be configured to send notifications or alerts to other electronic devices. For example, the controller 112 may be configured to send notifications or alerts to a module 140 (see FIG. 4A) mounted on the arm of the wheelchair at a selected radio frequency, via BLUETOOTH, or via WI-FI to another electronic device, such as a user's or caregiver's smartphone 142 (see FIG. 4B). The controller 112 may be powered by an external or internal battery, such as a rechargeable battery or battery 118.

[0034] In some embodiments, the controller 112 may be configured to wirelessly transmit an alert to the module 140 and / or the user's or caregiver's smartphone 142 at least characteristics related to the status of the pump 108. In some embodiments, the controller 112 may be configured to operate and / or control the pump 108. In some embodiments, the controller 112 may control the pump 108 based on the status of the volume of fluid detected by the volume sensor 128 in the fluid collection container 106. For example, based on data from the sensing means 110, the controller 112 may activate the pump 108 to cause fluid to flow from the fluid collection device 102 to the fluid collection container 106. The controller 112 may stabilize the pump 108 when the volume of fluid in the fluid collection container 106 reaches a predetermined threshold. In some embodiments, the controller 112 may wirelessly transmit the alert and a selected frequency, e.g., a selected time interval and / or volume interval. The controller 112 may wirelessly notify the module 140 or the user's or caregiver's smartphone 142 when the battery 118 is low. The controller 112 may send an alert to the module 140 or to the user's or caregiver's smartphone 142 if the pump 108 or the fluid collection system 100 is malfunctioning. In some embodiments, the controller 112 may be configured to control all operations of the pump 108.

[0035] The controller 112, according to one embodiment, may include at least one computing device 114. The at least one computing device 114 may be an exemplary computing device that may be configured to perform one or more of the functions described above. The computing device 114 may include at least one processor 146, memory 148, storage device 150, input / output ("I / O") devices / interfaces 152, and communications interfaces 154.

[0036] In some examples, the processor 146 may include hardware for executing instructions (e.g., instructions for performing one or more portions of any of the methodologies disclosed herein), e.g., instructions that constitute a computer program. For example, to execute instructions, the processor 146 may retrieve, decode, and execute instructions from an internal register, an internal cache, memory 148, or storage device 150.
