Toilet with integral microscope slide
An analytical toilet comprising a bowl adapted to receive excreta; a channel in fluid communication with the bowl for extracting a sample of excreta from the bowl; an imaging section in the channel, comprising a transparent window; and a movable wall capable of moving between a first and a second position; wherein the channel is open when the movable wall is in a first position; and wherein the channel is nearly closed when the movable wall is in a second position; a first actuator adapted to move the movable wall between its first and second position; an imaging sensor positioned to image the contents of the channel at the point of the movable wall through the transparent window is disclosed.
1. An analytical toilet comprising:
a bowl adapted to receive excreta;
a channel in fluid communication with the bowl for extracting a sample of excreta from the bowl;
an imaging section in the channel, comprising:
a transparent window; and
a movable wall capable of moving between a first and a second position;
wherein the channel is open when the movable wall is in a first position; and
wherein the channel is nearly closed when the movable wall is in a second position;
a first actuator adapted to move the movable wall between its first and second position;
an imaging sensor positioned to image the contents of the channel at the point of the movable wall through the transparent window.
2. The analytical toilet of claim 1 wherein the transparent wall is positioned on the opposite side of the channel from the movable side.
3. The analytical toilet of claim 1 wherein the transparent wall is part of the movable side.
4. The analytical toilet of claim 1 wherein the imaging sensor comprises a microscopic lens.
5. The analytical toilet of claim 1 wherein the imaging sensor is positioned below the channel.
6. The analytical toilet of claim 1 further comprising a light source illuminating the imaging section of the channel.
7. The analytical toilet of claim 6 wherein the light source is behind the transparent window.
