The toilet knows your secret

Who knows your health best in the future, maybe not your doctor, but your toilet. Even family doctors can't monitor you all the time. At least they can't do anything about defecation.


Recently, a research team from Stanford University developed a prototype smart toilet with four cameras, which was published in the journal Nature. This toilet analyzes the duration of your defecation and urination as well as various indicators of feces and urine to monitor your health status.


The researchers said that this study is committed to the current treatment stage of precision medicine, to early detection, early prevention stage.


Compared with the intelligent toilet which mainly focuses on cleaning and sterilization in recent years, this intelligent toilet with "four eyes" has much greater ability - it not only armed with a variety of detection instruments, but also has a deep learning "brain". In the health analysis of users, researchers confidently say that "its performance can be compared with that of trained medical personnel".


The ideal state to use this intelligent toilet is that when the user starts to use the toilet, the toilet has been detected by infrared motion sensor and pressure sensor, and starts to work. If the user starts to urinate, the toilet will automatically extend the test paper to collect urine and observe the urine flow through one camera; after the user urinates, another camera will observe the shape and mobility of the stool sample.


By analyzing the white blood cell count and specific level of protein in the urine, this intelligent toilet can find out whether the user has diabetes, metabolic abnormality, liver disease, even prostate cancer, bladder cancer and other diseases as early as possible. The analysis of stool morphology is important for the diagnosis of gastrointestinal diseases, such as malnutrition, pancreatitis, infection and cancer.


In order to prevent the toilet from confusing the excretion information of people living under the same eaves, researchers also designed a special "chrysanthemum recognition ability" for it. Like fingerprint recognition, it can design unique files for users by identifying the skin "anal membrane" near the anus.


In good taste, make complaints about the nose and vomit. So poker faced with such a serious talk of excrement and urine. But in fact, Dr. yanye Yiji, who has been studying intestinal bacteria for many years, once called in his book "defecation", that feces are "letters" of the body, and like breath, sweat and saliva, they are messengers carrying the health code of the body.


Generally speaking, it is very important to have continuous health monitoring for individuals. But the traditional methods of blood test and X-ray are not only expensive and complicated, but also easy to make people feel pain and tension.


In contrast, breathing, sweating, saliva secretion, urination and defecation are the inevitable physiological activities of people every day. These secretions themselves hide rich information, and are naturally expected to become the first scouts in the human health station.


Just as the group of scientists who are trying to monitor health through smart toilets, researchers in different corners of the world are also tirelessly studying the "code" brought by these scouts.


In August 2019, researchers of medical engineering at Caltech developed a wearable wireless sweat sensor, which can judge the user's physical and even mental state by measuring the metabolites and some neuronal markers in the sweat in real time.


The sensor, made of graphene, can analyze the rate of sweating, as well as the sodium, potassium and glucose in the sweat, to monitor users for cardiovascular disease, diabetes or kidney disease. Its upgraded version can also monitor the user's cortisol level, a substance called "human stress hormone", which is closely related to mental disorders such as anxiety, post-traumatic stress disorder and depression.


The novel coronavirus pneumonia epidemic has been attracting unprecedented attention in the world. Want to judge whether they are infected, go to the hospital to see a doctor and worry about cross infection, this problem plagues high-risk groups.


Novel coronavirus pneumonia has been developed by a team of Professor Dina Catabi of electrical engineering and computer science at Massachusetts Institute of Technology in the recent past. It has been used in remote screening of new crown pneumonia patients by Dina Katabi. This machine is similar to a router that transmits and receives Wi Fi signals. It can capture the breath, movement and sleep of the monitored person in real time.


These data can help medical staff to remotely screen the health status of the monitored people, not only reduce the risk of exposure and infection, but also focus more on the severe patients. The device has now been tested at a Framingham medical facility on the outskirts of Boston. The team's longer-term goal is to use it to monitor the health of patients with chronic diseases, such as high blood pressure and Alzheimer's disease.


At the same time, online consultation has become a choice for more people. On April 18, wired magazine and Caesar djajaherian, one of the founders of carbon health, a health care provider, discussed the future of telemedicine in a live Facebook broadcast. Caesar believes that telemedicine plays a more and more important role in people's life, from the traditional way of understanding patients' needs through telephone, to video interaction with patients, to diagnosis and treatment of patients with the help of Apple watch, remote stethoscope and other devices.


In addition to saliva and breathing, scientists are still exploring more physiological states that hide human health codes. For example, sleep is still a relatively mysterious field in human biology. Emmanuel mignot, a professor of psychiatry and behavioral science, is working on a lightweight, accurate sleep measurement headband. The study is expected to allow patients to diagnose sleep disorders at home, rather than running to a hospital to use a cumbersome and complex polysomnography (PSG).


With these health monitoring "housekeepers" becoming more and more personalized and private, how to protect the privacy of the collected objects has become a problem that can not be ignored.


Like a raging fire in the novel coronavirus pneumonia market, the GDPR has been developing guidelines for the protection of health information, tracking tracks and contact tracking data of the new crown pneumonia patients.


At this point, the team working on smart toilets has solemnly assured people that your files will be stored in a secure cloud system, will not be individually identified, and will be protected by a special healthcare bill HIPAA when sent to healthcare workers.


Two thousand years ago, Bian que, a miracle doctor, had a conversation with King Wen of Wei about medical skills. He said that the one who is best at medical skills is not the one who returns to the spring with a smart hand, but the elder brother who "looks at God when he is ill, but does not remove him physically". Maybe in the near future, such diagnosis and treatment will become a reality.
