Toilet with Health and Wellness Sensors in the Lid

Abstract

An analytical toilet comprising a bowl for receiving excreta from a user; a lid adapted to cover the bowl; and a first health and wellness sensor in the lid for measuring a characteristic of the user's excreta is disclosed.

Description

TECHNICAL FIELD

The present disclosure relates to analytical toilets. More particularly, it relates to analytical toilets that seal the bowl to perform analytical tests and for cleaning.

BACKGROUND

The ability to track an individual's health and wellness is currently limited to the lack of available data related to personal health. Many diagnostic tools are based on examination and testing of excreta, but the high cost of frequent doctor's visits and/or scans make these options available only on a very limited and infrequent basis. Thus, they are not widely available to people interested in tracking their own personal wellbeing.

Toilets present a fertile environment for locating a variety of useful sensors to detect, analyze, and track trends for multiple health conditions. Locating sensors in such a location allows for passive observation and tracking on a regular basis of daily visits without the necessity of visiting a medical clinic for collection of samples and data. Monitoring trends over time of health conditions supports continual wellness monitoring and maintenance rather than waiting for symptoms to appear and become severe enough to motivate a person to seek care. At that point, preventative care may be eliminated as an option leaving only more intrusive and potentially less effective curative treatments. An ounce of prevention is worth a pound of cure.

At present, there is no easy, hands-off way of measuring human waste weight, volume, density, content, or other characteristics. While each can be done, there is no know automated method integrated in a toilet. Weighing an entire toilet is difficult and traditional toilets do not hold the entire urine event in the bowl, so the best that can be done is to measure the weight of a person before and after using the toilet. This could measure total excreta mass, but there would be no distinction between liquid and solid waste. Also, when you are measuring a small change in weight from a much larger weight (like the weight of waste compared to the weight of an adult) the measurement will typically be less accurate.

Exemplary Embodiments

The present disclosure relates to a toilet with a bowl and seat supported by a frame. The frame includes at least one lifting mechanism adapted to raise and lower the seat and/or bowl. In some embodiments, there may be separate frames for supporting and adjusting the seat and for supporting and adjusting the bowl. Preferably, the lifting mechanism is further adapted to change the angle of the seat.

In a preferred embodiment, the toilet comprises a motorized seat lift that is integral with and internal to the toilet. It also provides customized lifting motions set to individual user's preferences. The disclosed toilet looks and feels like a conventional toilet and can help prevent fall by keeping a person more supported during a lift and help them to their feet at a height appropriate for the individual.

In a preferred embodiment, the adjustable frame allows the toilet to be both shorter and taller than conventional toilets. This makes the toilet more comfortable and easier to use for both tall and short users, including children, without the need for special stools or spacers.

In various exemplary embodiments, the bowl is supported by a frame including at least one actuator. In various exemplary embodiments, the seat is supported a frame comprising at least one actuator. In various exemplary embodiments, the frame comprises two, three, four, or more actuators for the bowl and/or seat. In a more preferred embodiment, the frame comprises three pairs of actuators to move the seat. Preferably, the actuators are controlled by a digital controller that coordinates the actions of the actuators to thereby provide a smooth lifting and lower at the desired speed. More preferably, the controller is programmable, so that users can program the lifting and lowering of the seat to their preference. Even more preferably, the toilet includes a user identification module, so that the user is automatically identified as he or she approaches or sits on the toilet.

Referring to FIG. 1, an exemplary embodiment of a toilet is shown with a closed lid 101, lowered foot platform 120, and retracted handles 210. FIG. 2 shows the toilet with an open lid 101, raised foot platform 120, and extended handles 210. In a preferred embodiment, handles 210 are adapted to be readily ripped by a user, especially while sitting or rising. In a preferred embodiment, the handles 210 move while the seat 200 is lowering and lifting a user to enable them to grip the handles 210 and use them for support during sitting and rising. The toilet is enclosed with a shroud 400.

In various exemplary embodiments, the shroud 400 covers all the internal support components that comprise the frame as well as the bowl 300 (i.e., the bowl is covered except for the top that would be covered by a lid). In preferred embodiments, the shroud 400 comprises at least one sections of articulated or flexible (e.g., elastic, material) assembled such that the shroud 400 can contract or expand as the frame 110 moves the bowl 300 and/or seat 200. Other sections of the shroud may be rigid. In various exemplary embodiments, the at least some portions of the shroud are removable or openable to allow access to the interior of the toilet frame. The interior of the toilet frame may include, among other things, plumbing connections, fluid supply lines, support structures, health and wellness assessment devices, electronic circuits, digital devices (e.g., processors, memory), storage tanks, and communication modules. In various preferred embodiments, cover 102 opens to allow access to the interior of the frame.

In various exemplary embodiments, the shrouds 400 are preferably designed for aesthetic and other purposes. For example, the shrouds 400 can be made in various colors to suit the decor of the bathroom the toilet is installed in. Besides colors, the shrouds 400 can include patterns or graphics so that the toilet 100 “makes a statement” in the bathroom.

In various exemplary embodiments, the handles 210 include at least one buttons, switches, sensors, etc. through which the user may control the seat, including, but not limited to, starting and stopping the seat 200, reversing seat movement direction, adjusting the position or angle of the seat 200, and adjusting the height of the bowl 300, seat 200, or foot platform 120.

In various exemplary embodiments, the handles 210 may include at least one health and wellness sensors. The sensors may be used to measure how hard the user is gripping and provide feedback to the lift control. For example, if a user suddenly increases their grip it is likely that they are struggling with standing or with their balance. Grip pressure may also be tracked over time. The sensors may also include detection for heart rate, body temperature, hand health indicators, light sensors, electrocardiogram, pulse, blood test (e.g., using a finger prick), etc. Toilet handles with health and wellness sensors are disclosed in U.S. Patent Pub. No. 2018/0084959, the entire disclosure of which is incorporated herein by reference in its entirety.

Referring to FIG. 3, an exemplary embodiment of a toilet 100 is shown. The toilet 100 includes a frame 110, bowl 300 supported by the frame 110, a lid 101, and a seat 200 also supported by the frame 110. In a preferred embodiment, the seat 200 is supported by two sets of seat actuators 111, 112, and 113, which can raise and lower the seat and change its angle to tile forward or back. In other embodiments, the number and arrangement of actuators may vary.

In a preferred embodiment, a pair of first seat actuators 111 are pivotally connected to a front area of the seat 200 and a pair of second seat actuators 112 are pivotally connected to a back area of the seat 200 providing support at four “corners” of the seat 200. The four seat actuators 111 and 112 are also pivotally attached to the frame 110. An additional pair of third seat actuators 113 are pivotally attached to the frame 110 at one end and pivotally attached to the second pair of seat actuators 112 at their other end. In another embodiment, the third seat actuators 113 are attached to the first pair of seat actuators 111.

FIG. 3 shows the toilet 100 with the seat 200 fully lowered to just above the top of the bowl 300. Actuators 111, 112, and 113 allow the seat to be adjusted for a variety of users from small children to tall adults.

Referring to FIGS. 4 and 4A, an exemplary embodiment of a floating toilet seat 200 according to the present disclosure is shown. The seat includes a rigid seat support 201 covered by a shroud 202. Weight sensors 203 are placed between the seat support 201 and floating cover 202. In various other embodiments, the weight sensors may be placed in a variety of places such as under the actuators or under the frame.

In various exemplary embodiments, the toilet continuously measures weight load on both the seat 200 and the foot platform 120. In a preferred embodiment, the system weighs the user on the foot platform 120 prior to the user placing any weight against the seat 200 and records that as the user's total weight. In some embodiments, the system calculates a user total weight using both the seat weight sensors 203 and foot platform weight sensors 121 after the user seated with the seat 200 fully lowered. In various exemplary embodiments, the system calculates the percentage of user body weight on the foot platform 120. The angle of the seat 200 is limited from raising based on the percentage of weight on the foot platform 120. This prevents the seat 200 from tipping to an angle that will not support the user's weight prior to the user being on their feet. The platform 120 is preferably comprised of a transparent material to facilitate the use of imaging sensors under the platform 120 for analyzing the bottom of the user's feet.

In various exemplary embodiments, the urine is tested for a variety of properties including volume, flow rate, color, weight, density, content, temperature, clarity, pH, settled gradient, and flow geometry. This may be done with a variety of sensors or testing methods including MOS, CCD, spectrometers, volume measurement devices, weight sensors, temperature gauges, chromatographs, mass spectrometers, and gas analyzers.

Referring to FIG. 5, an exemplary embodiment of an analytical toilet 1100 is shown. In various exemplary embodiments, sensors in the lid collect data with the lid 1101 closed. Such first sensors 1102A may include imaging sensors such as CCD, MOS/CMOS, IR camera, visible light camera, 3D camera, near-IR camera, and UV camera. They may also include spectrometers that measure light that has passed through the excreta or reflected off of it. The interior of the bowl 1300 may be illuminated with visual, infrared, near infrared, ultraviolet, or other wavelengths by light sources 1103 to enable use of these sensors.

In various exemplary embodiments, the lid 1101 also includes one or more second health and wellness sensors 1102B. The second sensors 1102B may interact with the user's back while using the toilet, as shown in FIG. 6. Such second sensors 1102B may include a stethoscope, an ultrasound probe, an echocardiogram probe, a temperature sensor, a durometer, an electrocardiogram lead, and a ballistocardiography sensor. Physical contact or close proximity with the user is necessary for many of these sensors. In various exemplary embodiments, the lid may contain microphones to measure the excretion profile or other sounds.

In various exemplary embodiment, the lid 1101, sensors 1102B, or other components in contact with the user's skin may include an ultrasound sensor. Ultrasound is used to image internal organs and may be used to track the size and shape of internal organs in the torso of a user detecting, for example, if an organ becomes swollen (e.g., appendicitis, infections).

In various exemplary embodiment, the lid 1101, sensors 1102B, or other components in contact with the user's skin may include a durometer. This is used to test skin hardness which may be indicative of conditions such as scleroderma which may harm blood vessels, internal organs and the digestive tract in addition to the skin. In various exemplary embodiments, the lid may also contain imaging sensors that detect conditions such as scaly skin, discoloration, changes or growth of moles that may be symptoms of more serious conditions.

In various exemplary embodiments, the lid 1101 includes a seal 1104 that forms an airtight or watertight seal creating a chamber including the bowl 1300. In such embodiments, the toilet 1100 may include second sensors 1102A in the lid or other sensors in the toilet system for testing the air in the chamber and/or passages for drawing air out of the chamber for testing elsewhere in the system. Such sensors or tests may include spectrometers, chromatographs, FET, nano-FET, MOSFET, mass spectrometers, thermometers (including IR and thermocouples), rheometers, pH detectors, and scent detectors. Drawing air out of the chamber may also aid in drying the bowl between uses to reduce the risk of cross-sample contamination. The air passages may also be used to increase or decrease pressure in the airtight chamber. This may be advantageous in preparing excreta for sampling or other purposes. In other embodiments, the seal may be water-tight or splash-proof for bowl cleansing.

In various exemplary embodiments, the seat 1200 includes one or more second health and wellness sensors 1207. Such second sensors 1207 may include a stethoscope, an ultrasound probe, an echocardiogram probe, a temperature sensor, a durometer, an electrocardiogram lead, and a ballistocardiography sensor.

In various exemplary embodiments, the inner surface of the lid 1101 may include an ultraviolet light source to disinfect the interior of the bowl or seat.

Referring to FIGS. 7A-D, another exemplary embodiment of a toilet seat 2200 with a floating hinge 2210 is shown. FIG. 7D shows the interior of hinge 2210. Some portions of the floating hinge 2210 may be integral to the seat or may be attached to the toilet seat 2200 with connectors (e.g., screws or bolts).

Referring to FIGS. 8A-B, show the components of an exemplary floating hinge 2210. FIG. 8A shows one side of the hinge 2210 assembly. FIG. 9B shows it from the opposite side. In various exemplary embodiments, the hinge 2210 comprises a floating hinge case 2213, pivot bar 2219, and floating hinge cover 2212 connected by screw 2211. Screw 2211 connects the cover 2212 to the case 2213 enclosing the pivot bar 2219. In some embodiments, the screw 2211 also connects the hinge 2210 to the seat 2200.

In various exemplary embodiments, pivoting bar 2219 comprises seat axle 2214, screw slot 2215, pivot axle 2216, and electrical connectors 2217 and 2218. Seat axle 2214 is adapted to connect to the toilet and provides a point around which the seat 2200 is raised and lowered. The pivot axle 2216 rotatably connects the pivot bar 2219 to the hinge case 2213. As will be described in more detail below, the screw slot 2215 allows the pivot bar 2219 to pivot around the pivot axle 2216 without interacting with screw 2211.

In various exemplary embodiments, connectors 2217 and 2218 are included to provide a supply of electrical power to components within the seat and lid, such as load cells, health and wellness sensors, processors, controllers, and wireless communication devices, among others. Connectors 2217 and 2218 may also provide data connections to similar components elsewhere in the system. In preferred embodiments, the electrical wiring connecting connectors 2217 and 2218 are molded into the pivot bar 2219.

Referring to FIGS. 9A-B, illustrate the range of motion through which the floating hinge 2210 is able to float. Pivot bar 2219 rotates around the axis of pivot axle 2216 within hinge casing 2213. Screw slot 2215 is adapted to allow this without interference from screw 2211. Seat axle 2214 is able to move up and down relative to the hinge casing 2213. When a user sits on the toilet seat, the weight of the user may cause the seat to lower slightly causing pivot axle 2216 to lower. Seat axle 2214 does not move because it is fixed relative to the toilet body. Because of the movement of pivot axle 2216, pivot bar 2219 moves relative to hinge casing 2213 such that seat axle 2214 moves upwardly and does not transfer the weight of the user to the toilet frame.

In various exemplary embodiments, the toilet seat lid comprises one or more health and wellness sensors that are adapted to interact with a seated user or to analyze the contents of the bowl with the lid closed. The sensors may interact with the user's back while using the toilet or may be collecting data with the lid closed. The interior of the bowl may be illuminated with visual, infrared, near infrared, ultraviolet, or other wavelengths by light sources.

In various exemplary embodiments, the toilet lid is powered through a connection to the toilet body. In a preferred embodiment, the connection may be made through the hinge between the lid and the body. In another embodiment, power is supplied through wires separate from the hinges. In various exemplary embodiments, the data connection to the lid may use the same wiring connections as the power or may be a wireless connection.

In various exemplary embodiments, urine and feces are separated into different collection basins for independent weighing and/or other analysis. In various exemplary embodiments, cameras estimate the volume of the fecal matter and use the estimated volume to estimate density.

In various exemplary embodiments, the toilet is capable of determining the total weight of excreta and the separate weights of solids and liquids. For example, weight may be measured after completion of an excreta event. Liquids may be allowed to exit the bowl and a new weight measurement taken of the remaining solids. The difference in weight provides the weight of liquid excreta. Alternatively, the urine may be drained off at a known flow rate or through a flow meter to measure urine volume leaving only solids to be weighed.

In various exemplary embodiments, a default position for the bowl and/or seat may be selected by the user. In such embodiments, the system will return to this position after being used by someone with a different preferred or optimal position. In various exemplary embodiments, the smart toilet may be programmed with separate default configurations for children and adults.

Preferably, the actuators are controlled by a digital controller that coordinates the actions of the actuators to thereby provide a smooth lifting and lower at the desired speed. More preferably, the controller is programmable, so that users can program the lifting and lowering of the seat to their preference. Even more preferably, the toilet includes a user identification module, so that the user is automatically identified as he or she approaches or sits on the toilet.

In accordance with the present disclosure, a smart toilet that includes mechanical, hydraulic, power, and data connections to accommodate a combination of health measuring tools is provided. An electrical connection to provide power to the health measuring tools is also provided.

In various exemplary embodiments, the smart toilet includes at least one sensor that analyzes imaging data. A processor analyzes the data to attempt to compare the user to known users for identification purposes. If a known user is identified, the position of the bowl and/or seat is automatically adjusted to the preferred position of the user. If the user is unknown or does not have a record preferred position, the processor analyzes the physical characteristics of the user (e.g., height, waist height, length of upper and lower legs) and adjusts the position of the bowl and/or seat accordingly. In some embodiments, facial recognition is used to identify users.

In various preferred embodiments, the system may identify a user based on their face, hand, or foot. In various preferred embodiments, the sensor may include a CCD (charge-coupled device) or MOS (metal oxide semiconductor), including CMOS (complementary metal oxide semiconductor). The sensor can be used, with proper calibration such as taking the data at a known distance, to measure the length of major bones. This data can then be used to customize the toiler position for an unknown user.

In various exemplary embodiments, the toilet system includes sensors for measuring the user's weight. This includes separate sensors for determining user weight on the seat and user weight on the user's feet. The user's weight that is supported by their feet is preferably measured using a platform adjacent to the toilet on which the user's feet are placed while sitting and while being lowered or raised from the toilet.

In the preferred embodiments, the toilet also includes health assessment devices supported by the frame. Examples of such devices include imaging cameras, flow spectrometers, volume measurement devices, body weight sensors, and gas analyzers. Toilets with such devices are described in the patents and published applications cited in the Background section above.

In various exemplary embodiments, the seat and bowl may be lifted together such that the toilet may be used as a urinal. In such a configuration, the system may be designed to flush with a reduced volume of water.

All patents, published patent applications, and other publications referred to herein are incorporated herein by reference. The invention has been described with reference to various specific and preferred embodiments and techniques. Nevertheless, it is understood that many variations and modifications may be made while remaining within the spirit and scope of the invention.
