MTEC NSTDA Delivers Pete Protect Against Negative Pressure Stretcher

The research, design and industrial solution team, MTEC, NSTDA has created an innovative negative pressure stretcher for the transport of COVID-19 patients or ‘PETE (Pete) protection stretcher’ designed with a strong, safe metal-free capsule section. Reduce the spread of COVID. Able to take the patient to X-ray and CT scan the lungs while on the stretcher to screen for symptoms in a medical facility Or moving patients between hospitals with an ambulance

(29 April 2021) at Hall, 1st floor, Office Building, NSTDA (Yothi), Rama VI Road, Bangkok: Ministry of Higher Education, Science, Research and Innovation (OWN) by the National Metal and Materials Technology Center (MTEC). C) National Science and Technology Development Agency (NSTDA) led by Mrs. Kulprapa Navanukroh Assistant Director of NSTDA, along with Dr. Sarawut Lerdplangsanti Head of Industrial Design Research and Solution And the MTEC research team NSTDA delivered PETE (Pete) protective stretcher: 5 sets of negative pressure stretchers to the hospital and the referral agency. Wid-19 To support the performance of medical personnel in the new coronavirus outbreak.

Mrs. Kulprapha Navanukroh Assistant Director NSTDA said that medical devices and devices are a sub-industry of the medical industry. In new target industries (New S-Curve) to meet the needs of driving Thailand to become an international health and integrated medical hub in
ASEAN, which requires knowledge and expertise in science. Technology and innovation As a mechanism for enhancing abilities In the country’s medical industry In which the use of technology It must not be too complicated. But with high security, NSTDA aims to use science and technology to create innovations that can be further developed and expanded to be useful in both the economy and society of the country. It also has a strong foundation for science and technology of the country. To increase the competitiveness of the healthcare and medical industries According to the goals of the Ministry of Higher Education, Science, Research and Innovation And government policies Especially the BCG Economy Model policy aimed at economic growth. Natural and environmental sustainability Including industrial sustainability as well, in the past NSTDA has accelerated the development of research and innovation. For supporting the COVID-19 outbreak Which has delivered more than 20 works covering both defense Reducing the spread and killing germs Including screening and early diagnosis For agencies with risk and demand for equipment Other works that are ready in production technology have already been further developed and technology transfer has been done to domestic entrepreneurs. As well as The ‘negative pressure cradle’, another innovation that NSTDA can develop and produce locally, will be another innovation to support and prevent the spread of COVID-19. In the new wave of epidemics, this includes the unforeseeable crisis in the future.

Assistant Director of NSTDA said today, the MTEC Research Team, NSTDA has delivered five sets of PETE (Pete) Stretcher: Negative Pressure Stretcher to transport patients, including: 1. Medicine Vajira Hospital Navamindradhiraj University 2. Erawan Field Hospital 2 of Vejkarun Hospital, Bangkok 3. Ruamjai Foundation (Khlong Toei), Bangkok 4. Vibhavadi Hospital, Bangkok 5. Saint Mary’s Hospital Nakhon Ratchasima Province To prevent the spread of new coronavirus disease, from ambulance transport to the patient’s lung X-ray and CT scan (CT scan) without removing the patient. From the negative pressure stretcher Helps reduce the spread of germs on medical devices and nursing homes.

Dr.Sarawut Lerdpalangsanti Head of Industrial Design Research and Solution The National Metal and Materials Technology Center (MTEC) NSTDA said the ‘negative pressure stretcher’ is one of the technologies being developed to stop the spread of pathogens during patient transport. In the past, the most common negative pressure stretchers on the market were limited in use and cost a lot. Recently, the MTEC research team NSTDA has invented the “Patient Isolation and Transportation Chamber” PETE stretcher, a device for transporting patients with respiratory tract infections, consisting of 2 main parts: a patient transport stretcher (Chamber). It is a transparent plastic capsule that fits the person’s body. And a negative pressure unit to control the air flow inside the stretcher When the patient is placed on the stretcher and the zipper is closed. The operator will turn on the automatic pressure adjustment system to allow the outside air to flow into the stretcher. Allowing the patient to breathe easily As the air passes through, the patient may contain breathing pathogens. Those air are then sucked through a HEPA Filter to filter out germs. And sterilized by UV-C light before being released to outside Ensuring that the air is sterile In addition to an efficient sterilization system The research team also developed a stretcher to provide a hole for the ventilator and a saline line to the patient. And there are 6 surgical gloves around the stretcher to facilitate treatment for healthcare workers.

Dr. Sarawut said in addition, the PETE stretcher also helps break the limit of use of conventional negative pressure stretchers on the market. The first part is the ‘Smart controller’ that controls the pressure inside the stretcher so it can be used both on the ground and on the air. Able to monitor air leaks to the outside (Pressure alarm) and alert to change the air filter (Filter reminder) when due. All of which are directly related to patient safety and epidemic control, where tests are performed according to international standards. The second part is ‘Stretchers can be brought into X-ray machines and CT scans’ because they do not contain metal. Therefore, the patient does not have to be moved from the negative pressure stretcher like any other device. Helps reduce the spread of infection to various tools. And air conditioning systems in the hospital And reduce the burden of cleaning The last part is The ‘stretcher folds down and is lightweight’ making it easy to carry and easy to install, ideal for ambulance use. Officials will be able to control the spread of the infection as well. This helps reduce the risk to healthcare workers and hospital users, especially during an outbreak.

The research team leader continued that PETE, a protective stretcher developed by the research team. Received advice from expert partners such as Asst. Prof. Anusaeng Jitsomkasem, Deputy Dean, Faculty of Medicine, Vajira Hospital Nawamindradhiraj University By focusing on the corner of the operator who needs to clean the stretcher quickly. The research team applied a nano spray gun containing benzionic disinfectant. Developed by Nanotech NSTDA. It can clean in 10 minutes and continue working immediately. It also gained expertise from Ajarn Kanoklak Dukarn, the director of the Institute of Industrial Pattern Development and Ready-made Garment Design (PATTERN IT), helping to design, tailoring and forming innovative stretcher to be strong and safe.

It is the result of Thai research that has passed ISO 14644 quality test and is in the process of making electrical safety standard IEC 60601-1 which confirms the safety standard. Recently, Suprira Innovation Co., Ltd. is a licensee to utilize and transfer technology to prepare for production and distribution.

Asst. Prof. Anusaeng Jitsomkasem, Deputy Dean, Faculty of Medicine, Vajira Hospital Nawamindradhiraj University, one of five hospitals to accept a negative pressure stretcher, said the COVID-19 outbreak was significantly important in the movement of COVID-19 patients. The presence of a negative pressure stretcher can significantly reduce sterilization. It also reduces the time Reduce the number of people required in epidemic situations. More importantly, it helps to be aware of the safety of healthcare workers taking care of COVID patients. Which are quite limited and work hard In the past 1 year, however, we have seen that face masks are an essential device to prevent contamination.
So now we have to say that the negative pressure cradle that MTEC NSTDA can do is an innovation that will drive manufacturers. And those related to medical equipment There is a driving force in the production of home-use medical devices.

“The COVID-19 outbreak Lately, we have suffered from not being able to buy masks from abroad. Just like a negative pressure stretcher On the day of the first coronavirus, the value of the negative pressure stretcher reached 6.5-7 hundred thousand baht despite the cost of more than a hundred thousand Therefore, our country must change the idea that We have to help our own country first. Which is a kind of medical security “
