Thai craftsmanship, patient-friendly medical inventions

COVID-19 epidemic It’s one of the important issues. and continues to spread today is therefore a source of development “Respiratory Screening Machine for COVID-19 Patients” as an alternative and more convenient than protruding the nose no need to draw blood and do not use saliva

Thiersit Nasamun, Postdoctoral Researcher from the Department of Pharmacy Faculty of Pharmacy Mahidol University One of the developers said that the working principle of the machine is the introduction of a technology calledelectronic nose or gas sensor to measure volatile organic compounds or the smell of a biomarker from the breath The research team has a database that can recognize and differentiate odors between infected and uninfected people.

It also brings the machine learning system. and artificial intelligence or AI into the processing, allowing for more accurate analysis and screening. Currently, the accuracy is about 97% based on the existing database of about 3,000 samples. The results are known within 5 minutes. The cost of the examination does not exceed 10 baht per person.

This research builds on the previous knowledge of the development of breath gas analyzers. which can indicate the disease. The first one is a breath-assisted blood glucose meter which has been used with diabetes for more than 10 years, making it a database and knowledge

When the COVID-19 situation Therefore, the idea was to build on the existing knowledge with the expertise of various departments. To create a new kind of innovation, the research team began collecting data and preliminary testing from 2020.

When there is enough information to gain confidence So began to ask permission to take the test in person officially. and more samples were collected at Rajavithi Hospital. Subsequently, research funding was received from the NIDA in 2021, enabling more samples to be collected and prototypes developed quickly.

Pisit Mitkuakul, President of the Aircraft and Radio Controlled Sport Association It said the innovation was made possible by integrating the expertise of a multi-disciplinary development team, including the Aircraft Simulator and Radio Control Association. Rajavithi Hospital Mahidol University and the private sector have applied for patents in 12 countries on 6 continents.

Currently, the submission process is being published in quality international journals. Including plans to apply for registration of innovation accounts artifact account and making various standards to be accepted

It is expected to be commercially available by the end of this year. And in the future, the device could be applied to other screening tests that use breath as an indicator or indication of abnormal conditions.

Test kit for chronic kidney disease screening

Patients with chronic kidney disease requiring ongoing treatment It is considered a health threat. Each year, both the state and its patients cost a lot of the disease. In addition, consumer behavior and food intake are the main causes of chronic kidney disease patients tend to be higher.

Assoc.Prof.Dr. Nattachai Srisawad, Lecturer of Department of Medicine Faculty of Medicine As the research team leader and Assoc. Prof. Kittinan Komolphis from the Institute of Biotechnology and Genetic Engineering Research Chulalongkorn University They co-invented the albuminuria test kit based on the principle of detecting micro albuminuria in the urine, which could be used as the most obvious indicator of chronic kidney disease.

This screening test works similar to a pregnancy test. Just collect urine in the morning after waking up or before breakfast. Then drop 3 drops onto the test strip and wait for results for only 15 minutes. If the microalbumin value is abnormal, there will be 1 bar, but if it is within the normal range, there will be 2 bars.A screening test is recommended once a year. even without symptoms to modify the consumption behavior of salty food

The screening kit is currently in the process of being approved for registration by the Food and Drug Administration (FDA). The research team expects the possibility of widespread adoption. and imported into the national health insurance system

“Rangsit University” measures sugar without having to draw blood.

A portable glucose meter without blood draw, the work of Chanidapha Tongjaihirun and Pattira Lapsomomboonying. Rangsit University student To help diabetics reduce injuries from blood draws. It is also easy to carry due to its small size. It is used for those who want to measure blood sugar levels from 70-350 milligrams per deciliter (mg/dL).

Operation of the apparatus on the principle of photoplasticism. It is measured by the pressure difference caused by the absorption of blood sugar. It uses infrared light and green light to measure the difference. By placing a finger on the sensor on the device, it can be measured and displayed in 20 seconds. The meter will display numerical blood glucose readings on the screen in milligrams per deciliter (mg/dL).

The College of Biomedical Engineering Rangsit University has cooperated with the Faculty of Medicine Vajira Hospital Nawamintrathirat University and Touch Technology Co., Ltd. developed such works. which has been successfully registered a petty patent and is undergoing clinical testing If the test result is satisfactory, then it will proceed to apply for certification from the FDA so that it can continue to produce and distribute commercially.
