The Dutch medical company has developed an artifact that can measure blood sugar with the eyes.

In recent years, more and more people with diabetes have been around. It is predicted that by 2032, approximately 600 million people worldwide will have diabetes. For people with diabetes, it is important to keep abreast of changes in blood glucose throughout the day. However, most blood glucose meters currently on the market measure blood glucose in a minimally invasive manner, and each time the blood glucose is measured is relatively large, depending on the patient's self-control. Therefore, measuring blood sugar every day becomes the most painful thing for diabetic patients.

Many companies want to revolutionize traditional methods of measuring blood sugar, and develop a non-invasive, real-time blood glucose meter that automatically records data, including Google's previous smart contact lens program. In 2014, Google announced a smart contact lens that detects blood sugar through tears. However, the thunder and rain of this project was small, and it was lost without taking out the product.

It is quite difficult to determine the glucose content in the blood by detecting the glucose content in the tears. At present, no scientists have announced a very clear correspondence. In addition, the concentration of glucose in the tears is very low, so the accuracy of the microsensor is extremely high. Finally, the size of the device and the comfort of wearing it all become a problem. After all, many people are very resistant to contact lenses, let alone a larger electronic device.

Under the numerous challenges, Google’s smart contact lens disappeared in 2015. Many people think that even Google can't make a decision. Using tears to measure blood sugar can only be a mirror. However, when everyone had no hope of measuring blood sugar with tears, the Dutch company NovioSense announced in 2015 that they used tears to measure blood sugar, micro-invasive, non-rechargeable, real-time monitoring of blood glucose sensors successfully tested in mice, and passed clinical Pre-test. In October 2016, NovioSense announced the completion of its fourth round of financing to fund the next phase of human clinical trials for tear sensor devices. The specific amount was not disclosed in this financing, but investors include Health Innovations, Topfonds Gelderland, and Fraunhofer. Ventures and NovioTech.

Our equipment will provide painless continuous blood glucose monitoring for all diabetic patients at a favorable price, NovioSense CEO Christopher Wilson said in a statement that users can use us by utilizing the NFC technology that most smartphones have. The painless, non-invasive sensor platform is connected to a smartphone to continuously monitor glucose data.

Like Google's smart contact lenses, NovioSense believes that the glucose content in the tears can be used to predict the body's blood sugar. Because the human body's tears continue to wash the eyeball, it is possible to monitor blood sugar levels in real time. But unlike Google, the teardrop sensor developed by NovioSense is not pie-shaped, but like a small stick.

The picture above is a device developed by NovioSense to measure blood sugar using tears. This small stick is a small flexible spring measuring 2 cm long and 1.5 mm in diameter. The entire device is coated with a soft hydrogel layer. This stick needs to be placed under the conjunctiva of the eye. The flexible material allows the stick to automatically adjust to the curvature of the lower eyelid of the wearer. The hydrogel layer can reduce the friction between the device and the eye, protect the surface of the eye from irritation and improve the wearing comfort. At the same time, the tear film of the human body will continuously wash the lower eyelids, and the small sticks can obtain biomarkers for monitoring the changes of tear sugar.

Chairs & Sofas For Elderly

Professional aging products are based on "knowing the old and understanding the old". The design of aging products should meet the real needs of the elderly, facilitate the care needs of nursing staff, and adapt to the home-based elderly care environment.
The characteristics of the elderly are aging of the lumbar spine, discomfort of the cervical spine, osteoporosis, and fatigue. Therefore, it is particularly important for the elderly to protect the waist and neck to delay the aging rate and reduce the incidence of diseases and accidents.
First, the backrest of the Chair is large and strong, and it is equipped with armrests, so that the waist of the old man is close to the back of the chair and can support the head and shoulders of the old man.
Second, the height of the chair should be at the same level as the knee, that is, when the old man is sitting, his feet can be placed flat on the ground. At the same time, the length of the chair seat should be the same as the length of the old man's hip to knee, so that the knee joint can be maintained at about 90 degrees, and the ankle joint can be in a natural drooping rest state.

Third, the chair should have some weight, and 3-4 kg is the best. If it is too light, it is difficult to maintain certain stability and easy to slip. The chair material should not be too soft.
