[0034] DESCRIPTION OF THE EMBODIMENTS

[0035] With reference now to the drawings, and in particular to Figures 1 through 19 thereof, a bedpan system embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

[0036] As illustrated in Figures 1 through 19, the human waste capturing device 10 generally comprises a bedpan 12, which is configured to be operationally engaged to a cleaning module 106 and to a waste management module 14 by means of a connection assembly 58, which is attached to the bedpan 12. The bedpan 12 comprises a first piece 18 and a second piece 20. The first piece 18 comprises a rearward section 22 and a pair of inner panels 24. In one embodiment, the rearward section 22 is wedge shaped, as is shown in Figure 6, so that the rearward section 22 is configured for insertion between a mattress 26 or pad and the buttocks of a user. The pair of inner panels 24 is attached to and extends forwardly from the rearward section 22 so that the inner panels 24 bracket posterior thighs of the user.

[0037] In one embodiment, padding 28 is attached to the first piece 18 to cushion a weight bearing area of the first piece 18 to increase comfort of the user. The padding 28 typically comprises of silicone, rubber, foam, or similar materials. The second piece 20, which comprises the receptacle 16 can be hingedly attached to a front edge 30 of the rearward section 22 of the first piece 18, as is shown in Figure 4. The first piece 18 thus is configured to hinge relative to the second piece 20 upon positioning of the buttocks of the user on the first piece 18. The receptacle 16 thereby remains substantially level or tilts downwardly away from the user, thus limiting the risk of spillage of bodily waste.

[0038] The second piece 20 comprises a bottom panel 32, which has a recess 34 which can be of any suitable shape, such as ovoid, positioned therein to define the receptacle 16. Each outer panel 36 of a pair of outer panels 36 is attached to and extends angularly and outwardly from a respective opposed edge 38 of the bottom panel 32. The outer panels 36 bracket the inner panels 24 and slide over one another as the first piece 18 hinges relative to the second piece 20. A front panel 40 is attached to and extends upwardly from the bottom panel 32. The front panel 40 also is attached to and extends between the outer panels 36. As is shown in the figures, the connection assembly 58 is attached to the front panel 40. The front panel 40 is dimensionally taller than the outer panels 36 thus is configured to direct urine to the receptacle 16, essentially serving as a splashguard. The front panel 40 is positioned, for example, convexly arcuate distal from the bottom panel 32, to increase user comfort during use of the human waste capturing device 10. The front portion 40 of the bedpan 12 can be designed to be sufficiently tall, or in another embodiment, can include an extendable structure to accommodate biologically male users. This design allows for the penis to be angled downward comfortably, ensuring that it fits within the receptacle without spillage or discomfort. The extendable feature can include a flexible or adjustable front section that can be raised or extended as needed, providing a customizable fit for users of different sizes. While the bottom panel 32, outer panels 36, and front panel 40 are described separately for descriptive purposes, in another embodiment the system is a unitary structure. Typically, the first piece 18 and the second piece 20 of the bedpan 12 are made of soft- touch and / or pliable materials to conform and / or to support the user during use of the bedpan 12.

[0039] In another embodiment, as is shown in Figure 13, the first piece 18 and the second piece 20 comprising a unitary structure so that the receptacle is not hingeable relative to the rearward section 22 of the first piece 18. Rather, the first piece 18 comprises resiliently compressible material, such as rubber, elastomer, foam, and the like. Upon positioning of the buttocks of the user on the first piece 18, the receptacle 16 remains substantially level or tilts downwardly away from the user, thereby limiting a risk of spillage of bodily waste and / or rinse water. In one embodiment, the system includes a removable and washable or disposable liner 224 that can be positioned within the bed pan. This liner enhances hygiene by allowing for easy removal and cleaning after use.

[0040] In one embodiment, the system includes a waste capturing system 136 comprising of the human waste capturing device 12.

In another embodiment, the utility housing 42 can be configured to rest on the floor near the bed 48, providing flexibility in installation.

[0041] The cleaning module 106 is attached to the connection assembly 58 and is configured to selectively direct water and air onto the genitals, perineum, and / or anus of the user. The cleaning module 106 facilitates both rinsing and drying with water and air, respectively, thereby enhancing hygiene for the user.

[0042] The cleaning module 106 includes a reservoir 50, which holds water and is attached to the utility housing 42. In one embodiment, the reservoir 50 is positioned within the interior space 44 of the utility housing. A spray nozzle 52 is connected to the bedpan 12 and is designed to direct water and air onto the genitals, perineum, and / or anus. As shown in Figure 5, the spray nozzle 52 is mounted on the front panel 40. In another embodiment, the spray nozzle 52 is hingedly attached to the bedpan 12, as depicted in Figure 6, allowing the direction of water and air to be adjusted. A lever 54 is connected to the bedpan 12 and operates the spray nozzle 52, enabling the user to selectively direct the water and air emitted from the nozzle. Other adjustment mechanisms for the spray nozzle 52, such as grooved wheels or slide tabs, can also be used. In one embodiment, a flap 56 is hinged to the bed pan 12, positioned over the spray nozzle 52 to shield it from bodily waste. The flap 56 deflects when water and air are emitted, allowing them to be directed toward the genitals, perineum, and / or anus of the user. Once the flow of water or air ceases, the flap 56 returns to its original position, covering the spray nozzle 52.

[0043] In one embodiment, the connection assembly 58, as shown in detail on the right in Figure 10, can include a three-way connector 192 that is attached to the spray nozzle 52. The cleaning module 106 also includes an air blower 60, which is equipped with a grip 62, allowing the user to hold and operate the air blower. Alternatively, the air blower 60 may be attached to the utility. The waste management module 14 is in fluidic communication with the bedpan 12 and is designed to connect to an air mover 78, allowing bodily waste to be transported from the bed pan 12 to the waste management module 14 via airflow. The waste management module 14 is configured to separate bodily waste from the air, ensuring the waste is properly segregated for disposal as the air continues through the module to the air mover 78 and housing 42, where it can be operated by a caregiver. In this context, the air blower 60 refers to any air-moving device, such as a pump, fan, blower, vacuum, or a similar mechanism.

[0044] The waste management module 14 includes a separator 80, which is mounted inside the utility housing 42 and positioned within the interior space 44. A vacuum connector 82 is also attached to the utility housing 42 and is in fluidic communication with the separator 80. This vacuum connector 82 is designed to connect to the air mover 78, enabling any standard vacuum cleaner with a hose to function as the air mover 78. In one embodiment, adapters can be attached to the vacuum connector 82, allowing connection to air movers 78 used in hospitals, nursing homes, long-term care facilities, or similar settings.

[0045] A waste tube 84 extends between the bedpan 12 and the utility housing 42, maintaining fluidic communication between the separator 80 and the receptacle 16. As shown in Figure 2, the waste tube 84 can be selectively connected to both the utility housing 42 and the bedpan 12 using tube connectors 86, which are attached to each component. A waste container 108 is positioned below the separator 80 and is designed to collect the bodily waste that has been separated from the air. Once filled, the waste and rinse water can be easily disposed of by emptying the waste container 108 into a toilet.

[0046] A switching valve 64, depicted in detail on the left in Figure 10, includes an inlet port 66 connected to the air blower 60. A first air hose 68 extends between a first outlet port 70 of the switching valve 64 and the reservoir 50. A second air hose 72 extends between a second outlet port 74 of the switching valve 64 and the three-way connector 192. Additionally, a water hose 76 extends from the reservoir 50 to the three-way connector 192. When activated, the air blower 60 directs air through the first air hose 68 to the reservoir 50, which forces water through the water hose 76 to the spray nozzle 52. The switching valve 64 can also be selectively switched to direct air through the second air hose 72 to the spray nozzle 52, allowing the user to alternate between rinsing and drying.

[0047] The bottom 88 of the utility housing 42 includes a discharge port 90. The waste container 108 is selectively attachable to the utility housing 42, establishing fluidic communication between the container and the interior space 44 through the discharge port 90. A trapdoor 92 is attached to the utility housing 42 and is positioned to selectively cover the discharge port 90. When the waste container 108 is attached, the trapdoor 92 automatically opens, as shown in Figure 9, allowing waste to flow into the container. Upon detachment of the waste container 108, the trapdoor 92 closes, as shown in Figure 8. Other mechanisms for selectively opening and closing the discharge port 90 can also be used, including sanitary valves, diaphragm valves, or similar alternatives.

[0048] In another embodiment, as shown in Figures 11, 12, 14, 17, and 18, the cleaning module 106 and the waste management module 14 are housed within a module housing 138, which defines an internal space 140.

The first end 116 is attached to the front panel 40 of the bedpan 12. The connection assembly 58 of this embodiment includes a liquid connector 110 and an air connector 112, both attached to the second end 118 of the connection housing 114. The liquid connector 110 connects the bed pan 12 to a source of pressurized water, which rinses the genitals, perineum, and / or anus of the user. The air connector 112 connects the bedpan 12 to the air blower 60, which provides drying after rinsing. The tube connector 86 is attached to the bottom 126 of the connection housing 114, facilitating fluidic connection between the receptacle 16 and the air mover 78. This allows for the removal of bodily waste and rinse water from the receptacle 16 and away from the user.

[0049] As shown in Figure 15, the first end 116 of the connection housing 114 features a vertical slot 132. This vertical slot 132 extends through the front panel 40. Both the liquid connector 110 and the air connector 112 pass through the connection housing 114 and protrude through the vertical slot 132. A sprayer nozzle 128 is attached to the liquid connector 110 and positioned within the bedpan 12. A knob 130 is rotationally attached to the first side 120 of the connection housing 114, allowing the user to control the sprayer nozzle 128. The knob 130 can be turned to selectively adjust the direction of water emitted by the sprayer nozzle 128.

[0050] The liquid connector 110 and the air connector 112 are designed to be vertically adjustable within the vertical slot 132. A slider 134 is attached to the first side 120 of the connection housing 114 and is operationally connected to both the liquid connector 110 and the air connector 112, allowing the user to adjust their position within the vertical slot 132. This ensures optimal positioning of the connectors for efficient cleaning and drying of the user.

[0051] The module housing 138 consists of a top 142, a bottom 144, and several sidewalls 146, which extend between the top 142 and the bottom 144. The cleaning module 106 within this embodiment includes a water tank 148, which can be filled with water and is selectively positioned inside the module housing 138.

The water pump 154 is in fluidic communication with both the water tank 148 and the water outlet 152. A water tube 156 connects the water outlet 152 to the liquid connector 110 of the bed pan 12, enabling the rinsing function.

[0052] An air outlet 158 and an air inlet 160 are positioned on respective sidewalls 146 of the module housing 138. An air pump 162, attached and located within the module housing 138, is in fluidic communication with both the air outlet 158 and the air inlet 160. An air tube 164 connects the air outlet 158 to the air connector 112 of the bed pan 12, enabling air-drying of the user.

[0053] The waste management module 14 in this embodiment includes a vacuum inlet pipe 166 and a waste inlet pipe 168, both positioned in respective sidewalls 146 of the module housing 138 and curving toward the bottom 144 of the module housing 138. A waste tank 170 is selectively positioned within the module housing 138 and can be attached to both the waste inlet pipe 168 and the vacuum inlet pipe 166. A second window 172 can be placed on a sidewall 146 adjacent to the waste tank 170, allowing for easy visual monitoring of the waste level.

[0054] A waste hose 174 is selectively attachable to the waste inlet pipe 168 and the waste tube 84 of the bedpan 12, enabling the transfer of waste and rinse water from the reservoir 16 to the waste tank 170. A vacuum hose 176 is attachable to the vacuum inlet pipe 166 and connects to the air mover 78, allowing airflow through the reservoir to guide the waste and rinse water into the waste tank 170. In some embodiments, a filter 188 is placed within the vacuum inlet pipe 166 to remove particulate matter from the air before it reaches the air mover 78.

[0055] A power supply 178 is attached to the module housing 138 and is operationally connected to both the air pump 162 and the water pump 154. As shown in Figures 11 and 14, the power supply 178 includes a power cord 180. In another embodiment, the waste capturing system 136 can be battery-powered. A switch 182, also attached to the module housing 138, controls the power supply 178 and is operationally connected to both the air pump 162 and the water pump 154, allowing selective activation of each pump. In one embodiment, where a water line, air line, and / or vacuum line are present in the patients' room, the power supply need not be present, as air, vacuum, and water can be supplied via opening and closing of valves.

[0056] The waste capturing system 136 can also include a controller 184, which is operationally connected to both the water pump 154 and the air pump 162, allowing selective activation of the cleaning module 106. As depicted in Figure 11, the controller 184 is accessible to the user while positioned on the mattress 26, enabling user control of the cleaning module 106. A power outlet 186 can also be attached to the module housing 138 and is connected to both the power supply 178 and the controller 184, as shown in Figure 14. The air mover 78 can be powered by the power supply 178 and controlled through the controller 184.

[0057] The controller 184 can be wired to the power outlet 186, the water pump 154, and the air pump 162, as shown in Figure 11, using a remote cord 190. In another embodiment, the controller 184 can function wirelessly, eliminating the need for wired connections.

[0058] In some embodiments, the system includes a port or adapter 216 designed to connect with a manual irrigation device 218 such as a syringe or similar manual irrigation device capable of dispensing fluid under pressure. This connection allows for manual irrigation and cleansing by caregivers or users, providing an additional method for thorough cleaning when automated processes may be inefficient or when more precise control is needed. The adapter 216 may be integrated into the second end of the connection housing 118 and ensures compatibility with various syringe sizes and types, enhancing the versatility of the system in different care environments and ensuring compatibility with a wide range of devices commonly found in healthcare facilities.

[0059] In another embodiment, as shown in figures 20 and 21, the bedpan 12 and / or module housing 138 is equipped with one or a series of sensors strategically positioned within the bedpan and / or module housing designed to monitor various operational parameters, such as moisture levels, waste presence, airflow rates, and the like, ensuring efficient and effective operation. In this embodiment, moisture sensor(s) 222 are located near the base of the bed pan and within the waste receptacle 16 to detect the presence of fluids. Once the sensor(s) measure the moisture level within the receptacle 16, they signal the control unit 214 to either activate an automatic shut-off feature, ceasing water flow to prevent overuse, or automatically activate the suction system to remove fluids from the waste receptacle to ensure efficient waste removal. Similarly, waste sensor(s) 208 can be positioned within the waste receptacle to detect the presence of solid and liquid waste. The control unit 214, which houses the automatic shut-off timer, continuously receives real-time data from these sensors. This data allows the system to adapt to the specific needs of each user and the control unit can also be programmed to adjust the preset shut-off durations based on the sensor feedback.

[0060] In another embodiment, as shown in figure 20, the module housing 138 includes an overflow-prevention valve 196 positioned at the top of the waste canister 170. This valve serves as a crucial safety feature, designed to mechanically and / or electronically stop the suction operation when the canister reaches its maximum capacity, thereby preventing waste from entering the vacuum system. The valve may utilize a float mechanism, diaphragm, sensor, or similar device to seal the suction inlet, halt further suction, and protect the vacuum system from failure or contamination.

[0061] In another embodiment, as shown in figure 20, the waste management module can also incorporate a built-in vacuum pump, which generates sufficient suction for waste removal and allows the system to operate independently of external vacuum devices. In another embodiment, this internal pump enables the system to function autonomously, eliminating the need for connection to external vacuum systems.

[0062] In one embodiment, as shown in figures 20, 21, and 22, the system includes a water pressure regulator 198 interfacing with the water pump 154, allowing for the selective adjustment of water pressure through the spray nozzle 128. This system may also include an air pressure regulator 200 to interface with the air pump, allowing similar adjustment of air pressure exiting through the nozzle 128. The pressure regulator is optionally operably connected to a user interface 202, such as a dial or touchpad, providing users or caregivers the ability to control or adjust the water pressure for a customizable cleaning experience. In some embodiments, the system is equipped with an automatic shut-off timer that controls the length of operation of the air, water, and suction components. The timer ensures that the system does not continue to operate indefinitely, shutting off the air, water, and / or suction after a preset period. Another embodiment would allow for the timer to be adjusted by the user or caregiver to accommodate varying usage needs. In one embodiment, as shown in figure 20, the connection housing 114 is equipped with a heating element for water and / or air. The water, stored in the water tank 148, can be heated before being directed through the spray nozzle 128, ensuring that the rinsing process is more comfortable for the user. Similarly, the air blower 162 can be configured to deliver heated air, providing an efficient and comfortable drying experience. The heated air can be adjusted by the user or caregiver through a temperature control interface 212, allowing for customizable temperature settings. The air blower 162 may be powered via a plug-in connection, as shown in the figures, or by a battery, allowing the device 10 to function without requiring access to an electrical circuit.

[0063] In one embodiment, as shown in figure 21, the system includes a camera, viewfinder, lens, or the like 230, integrated into the bedpan 12. This feature allows caregivers or users to visually inspect the cleanliness of the genitals, perineum, and / or anus after the rinsing and / or drying process. The camera, viewfinder, lens 230, and the like can be positioned near the spray nozzle 52 or in a location that provides a clear view of the areas being cleaned. The visual feed can be observed locally or displayed on a connected monitor or handheld device, enabling real-time inspection and ensuring proper hygiene. This feature reduces the need for manual checks by caregivers, providing a more efficient and thorough cleaning process.

[0064] In one embodiment, the system features an adjustable suction valve is integrated in the waste tube 156 fluidic line. This valve allows for precise control over the amount of suction being applied during the waste removal process. By adjusting the suction rate, the user or caregiver can prevent premature removal of water during the rinsing phase, ensuring that the cleaning process is not disrupted. The valve is adjusted through a user interface, providing flexibility based on a user's needs. As shown in figure 21, an adjustable air flow valve 228 is also used to regulate the amount and flow of air used in drying when connected to a variable air flow device - such as those commonly found in hospital rooms at the bedside alongside a central vacuum system outlet and regulator.

[0065] One embodiment describes the waste capturing system including one or a plurality of sensors integrated into the module housing. These sensors are configured to monitor the pressure of both the water and air flowing through the respective pumps within the system. The water pressure sensor 204 is positioned within the fluidic communication pathway between the water tank and the water pump, while the air pressure sensor 206 is located within the air pathway between the air blower 162 and the air outlet. In one embodiment, the system is equipped with a set of diagnostic sensors positioned throughout the module housing, specifically monitoring the operation of the air pump 162, water pump 154, and vacuum system. These sensors are strategically placed to detect any malfunctions or abnormal conditions that can occur during the operation of the system. In another embodiment, the system includes a waste level sensor 208 installed within the waste tank of the waste management module designed to detect the volume of bodily waste as it accumulates and when approaching the tank's maximum capacity, the sensor sends a signal to the controller, which triggers an alert to notify the caregiver or user. In some embodiments, the system can be configured to automatically halt the suction mechanism once it reaches full capacity; preventing any potential overflow, spillage, or vacuum system contamination.

[0066] In use, the human waste capturing device 12 enables a method 94 for managing bodily waste excreted by a bedbound user.
