Needle free diabetes care: 7 kinds of painless blood glucose measuring instruments

for millions of diabetes patients, can the day of daily blood glucose level monitoring through finger pricking be over

diabetes affects more than 422million people worldwide. People with diabetes have to test their blood sugar several times a day, usually by pricking their fingers with a long needle. This may be uncomfortable and painful for many people, which may lead to a reduction in the frequency of detection, thereby reducing the control of blood glucose levels

several companies in Europe are looking for needle free alternatives that can make the lives of millions of people easier. Some of these products are already available and others are still under development. Let's take a look:

freestyle libre

for British patients with diabetes, freestyle Libre is composed of a small sensor patch that can be worn on the arm for up to 14 days. Developed by Abbott diabetes care, this device is used to measure the glucose level in the interstitial fluid between cells below the skin

although the measurement is not as accurate as using blood tests, the device allows patients to use readable devices or download applications on the to continuously and wirelessly monitor their blood glucose levels


glucotrack is developed by the Israeli company integrity applications. It can measure the blood glucose level through the combination of ultrasonic wave, electromagnetic wave and thermal wave. To provide a reading, the sensor is clamped to the ear

the device is intended for adults with type 2 diabetes. It has been approved in Europe. The company has just begun to commercialize the glucose monitor


eversense is a subcutaneous implant developed by senseonics, which can be used for 3 months. The device can use a polymer that generates fluorescence in response to glucose level to measure glucose in interstitial fluid under the skin of the arm, and then send the data to a transmitter that displays glucose water in real time. It should be noted that antirust oil is often applied

this device has recently been approved by the US FDA, and the company has also reached an agreement with Roche to sell the sensor


glucowise is a sensor under development. It can measure blood glucose level simply by placing the device on the earlobe or the skin between the thumb and index finger. Real time measurements can then be sent directly to intelligent applications

by using radio waves to measure blood glucose levels, developers believe that the device should be more accurate than other wireless glucose monitors. The company behind it, mediwise, has conducted the first test among healthy volunteers and is currently preparing to test the prototype in patients with diabetes


noviosense is a Dutch start-up company dedicated to developing a glucose sensor that can be placed under the lower eyelid, which can wirelessly send glucose measurement data from the lower eyelid to the intelligent. The device consists of a flexible metal coil with a length of only 2cm and contains a nano sensor inside. In turn, the coil is covered with a layer of soft water gel. The technical complexity of ABS production and the investment in ABS Project are the largest projects in the aluminum processing industry

the coil can measure the change of tear glucose level per minute by using the same enzyme technology without pollution as the traditional glucose test paper. The device has been tested on animals, and the company is currently planning to conduct clinical trials


glucose is a derivative product of the University of Leeds in the UK, which is developing a laser technology to monitor glucose levels. The device is made of a kind of Nano Engineering glass, which will emit fluorescence under the stimulation of low-power laser

when the glass contacts with the user's finger skin, the reflected fluorescent signal will be measured within 30 seconds according to the change of glucose concentration in their blood

Google smart contact lens

as early as 2014, the eye care departments of Google (Google) and Novartis (Novartis), which have natural repair and are often accompanied by new injuries, cooperated to develop an intelligent contact lens that can be used to measure glucose levels. The lens will include a thin microchip to measure glucose and an antenna to send information to the smart

however, there has been no major progress update on the project since then, and it is not known when the first trial will start. Meanwhile, Korean researchers are developing their own glucose sensing smart contact lenses, which have been proved to work in animals

with the development of so many players and technologies, diabetes patients will have many choices in the future. The days of holding hands to measure blood sugar will be over. (compiled by Sina medicine/david)
