The present disclosure relates to the field of devices useful in assessing health and wellness. More particularly, it relates to the use of imaging technology on legs and feet to assess health and wellness.
Not all people have the same height or body dimensions. However, nearly all toilets come in only a very small variety of heights. This can make it particularly difficult or uncomfortable for those who are among the tallest and shortest, or more specifically those with the longest and shortest legs, to lower down, sit, or rise from the toilet seat. Conventional toilets also lack any way to adjust the height of the feet. Raising the feet can only be accomplished with stools, typically having a fixed height.
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.

The present disclosure relates to a toilet with a bowl and seat supported by a frame. The frame includes one or more lifting mechanisms 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 users 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
In various exemplary embodiments, the handles 210 include one or more 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 one or more 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, cameras, 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
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 actuators 113 are attached to the first pair of seat actuators 111.
The foot platform 120 is adapted to provide for imaging sensors 134 to examine a user's feet. Imaging sensors 134 are positioned above, to the sides, and below the user's feet on the arms 135, outer crossbar 132, and base crossbar 133. The imaging sensors 134 may be visible light, infrared, near infrared, thermal, and/or 3D sensors. 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. A foot platform and imaging sensors of this type are described in U.S. patent application Ser. No. 16/578,118 filed on Sep. 20, 2019, which is incorporated herein by reference in its entirety.

Referring to
In various exemplary embodiments, the angle of the foot platform frame 130 relative to the floor changes as it is pivoted by motor 140. Actuators 131 rotate the flatform 120 relative to the frame 120. This allows the platform 120 to be kept parallel to the floor at any height or to be adjusted to a different angle for greater comfort. This includes using the platform 120 to raise the knees to a more ergonomic position (i.e., “squatty potty”) or more comfortable angle for the feet and ankles.
In various exemplary embodiments, the toilet includes one or more sensors to examine the user or excreta. The sensor may be an imaging sensor, which is preferably one or more of, but not limited to, CCD (charge-coupled device) or MOS (metal oxide semiconductor), including CMOS (complementary metal oxide semiconductor), IR (infrared) detector, near IR detector, and visible light detectors. In various exemplary embodiments, a light source emits visible and/or non-visible light across one or more ranges of wavelengths as appropriate for any particular detection method (e.g., spectrometry). The sensor may also be one or more of, but not limited to, CCD, MOS/CMOS, spectrometers, chromatographs, FET, nano-FET, MOSFET, mass spectrometers, electrodes, microphones, load cells, pressure gauges, PPG, thermometers (including IR and thermocouples), rheometers, durometers, pH detectors, and scent detectors.
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 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.
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.
