RuiRen Medical Files IPO Prospectus: Pioneering Wearable Vital Signs Monitoring and IoT Solutions Bridging Home and Hospital Care

Since the outbreak of the epidemic, many enterprises have upgraded their products to leverage technology in the fight against the pandemic. Beijing Raiing Medical Technology Co., Ltd. (hereinafter referred to as “Raiing Medical”) is one such company.

Raiing Medical is a pioneering innovator in the field of wireless wearable temperature monitoring, specializing in the research and development of wearable vital signs monitoring devices. It provides IoT solutions, data, and artificial intelligence services, aiming to assist physicians in better diagnosis, management, prevention, and intervention, while empowering individuals to more effectively manage their own health.

Dong Xinyu, COO of Raiing Medical, told VCBeat: “In response to the pandemic, as a leading enterprise in the field of health monitoring, Raiing Medical has upgraded its existing products—including wearable thermometers, IoT devices, and software systems—urgently developed related software and data services, and launched two wireless temperature monitoring and management systems tailored for the COVID-19 epidemic.”

The first type of wireless temperature monitoring and management system is designed for scenarios such as isolation wards in hospital departments including pulmonology, emergency medicine, infectious diseases, and intensive care units (ICU). It enables continuous patient temperature monitoring and supports features such as multi-bed central monitoring, high-temperature alarms, trend curve review, temperature chart printing, and one-click bed transfer.

“Meanwhile, installing a central management workstation at the nurses’ station can reduce the workload of healthcare personnel, decrease the frequency of their entries into and exits from the infection zone, lower the risk of infection, and minimize the waste of supplies such as protective suits.”

Another system is cloud-based central monitoring for scenarios such as home observation and centralized quarantine in hotels. Users can connect a wireless thermometer to their mobile phones to view their real-time body temperature data, while the data is automatically transmitted to the cloud. Community and medical administrators can monitor the temperature changes of all individuals under observation via a web platform. “This system enables community managers to obtain temperature data without home visits, which not only saves significant manpower but also prevents cross-infection within communities.”

For example, Beijing Raiing Medical Technology Co., Ltd. has provided wireless temperature monitoring devices and corresponding software to communities in certain areas of Sichuan Province. In collaboration with enterprises such as Penguin Doctor and China Telecom, the company has integrated real-time body temperature data of individuals under observation into a customized app. Community administrators can use the app to view users’ real-time body temperatures, daily maximum temperatures, and temperatures recorded at fixed morning and evening reporting times.

“The relevant authorities are highly satisfied with the system’s application outcomes and have implemented related services across 10 sub-districts and communities under their jurisdiction.”

To date, Raiing Medical has distributed more than 10,000 wireless thermometers. In hospital isolation wards, the company has installed over 100 beds, served more than 200 confirmed COVID-19 patients, and accumulated over 60,000 hours of temperature monitoring. In community settings, Raiing Medical has launched six projects across Sichuan, Beijing, Zhejiang, and Hubei, monitoring more than 3,000 individuals and accumulating over 400,000 hours of temperature measurements.

Regarding the impact of the pandemic on companies in the industry, Dong Xinyu identifies three key points: First, strengthening public health prevention and control makes mobile wearable continuous monitoring an essential component. Second, within the intelligent monitoring ecosystem, companies in the industry will have more opportunities for mutual collaboration. Third, as the pandemic continues to evolve globally, companies that, like Raiing Medical, have consistently focused on international markets will develop more international partnerships.

Furthermore, unlike consumer-grade medical products, Raiing Medical’s wireless temperature sensors are primarily deployed in healthcare institutions and clinical settings, necessitating high-precision performance.

“Although it is a surface monitoring solution, Raiing Medical’s wireless temperature products feature non-invasiveness, remote capability, and high-precision temperature monitoring. With continued use in dozens of hospitals across China and the accumulation of data, there is potential for further improvement in product accuracy.”

In fact, Raiing Medical has been accumulating technologies such as continuous temperature monitoring since 2008, investing significant time and effort in both hardware and algorithms. Dong Xinyu introduced, “Raiing Medical began its strategic expansion into the clinical market in the second half of 2016, collaborating with the anesthesiology departments of approximately thirty Grade A tertiary hospitals across China.”

In the Department of Anesthesiology, to ensure the accuracy of temperature data, monitoring methods are predominantly invasive core temperature measurements, such as esophageal, bladder, rectal, and nasopharyngeal temperature monitoring.

To enhance the accuracy of wireless temperature monitoring, Raiing Medical conducted extensive comparative studies between its wireless temperature measurements and esophageal temperature readings, progressively optimizing its algorithms. The results have been highly satisfactory. An article published in the prestigious journal *Anesthesia & Analgesia* in March 2018 demonstrated that the mean difference between Raiing Medical’s wireless temperature measurements and core body temperature measured via the esophagus was only 0.14°C.

In January 2020, experts from West China Hospital of Sichuan University published another study showing that in adult ambulatory surgery, the temperature measured by Raiing Medical’s wireless thermometer differed from human esophageal core body temperature by only 0.06°C, with a standard deviation of ±0.26°C. Dong Xinyu stated, “This is not our endpoint. We will continue to optimize our algorithms and further enhance product capabilities.”

Optimizing algorithms and developing products naturally rely on the R&D team of Raiing Medical. The company’s research and advisory teams comprise medical experts and seasoned medical device R&D specialists from top-tier institutions worldwide, including Harvard University, Yale University, and Tsinghua University.

In addition, Raiing Medical collaborates with medical institutions such as Peking Union Medical College Hospital, West China Hospital of Sichuan University, Cleveland Clinic, Boston Children’s Hospital, Massachusetts General Hospital, Texas Medical Center, and UZ Leuven in Belgium on joint research projects.

From R&D to commercialization, Raiing Medical aims to delve deeply into clinical scenarios and uncover unmet needs, continuously developing new products in the field of wireless wearable vital signs monitoring. Its increasingly strong market performance serves as the best testament to its commitment to addressing clinical demands.

Raiing Medical’s consumer-facing wireless thermometer is branded as “Fever Director.” With rapid growth in the consumer market, Raiing Medical took proactive measures and began strategically positioning itself in the clinical market in 2016.

“We aim to supplement mobile wearable monitoring for clinical scenarios that traditional monitors cannot reach. Mobile wearable monitoring can bridge more clinical scenarios, allowing patients to enjoy better services.”

Dong Xinyu provided an easy-to-understand example: laptops can be used in scenarios where desktop computers cannot, such as during business trips; meanwhile, mobile phones are widely applicable in situations where laptops fall short, such as shopping, socializing, communication, reading, or online entertainment in fragmented time slots. Therefore, mobile phones are not merely smaller in size; more importantly, they have unlocked a vast ecosystem.

In the realm of medical-grade monitoring products, there are numerous desktop monitors, and large-scale medical devices often face challenges in reaching certain scenarios. This presents a growth opportunity for mobile wearable monitoring products, which is also the future focus of Raiing Medical.

“Mobile wearable monitoring is not meant to replace ‘desktop monitors,’ but rather to supplement and enhance the clinical scenarios reached by monitoring products, thereby expanding the market for vital signs monitoring. Mobile wearable monitoring will unlock an entirely different ecosystem, one in which vital signs monitoring may involve everyone.”

To achieve its clinical market layout, Raiing Medical has developed a range of products for clinical scenarios, such as wireless multi-parameter sensors that monitor four vital signs: temperature, respiration, heart rate, and electrocardiogram (ECG); an intelligent surgical anesthesia temperature monitoring and management system suitable for operating rooms and post-anesthesia care units (PACU); and an intelligent multi-parameter wireless bedside mobile and central monitoring management system that facilitates hospital management...

They are still on their journey, and we look forward to the day when Raiing Medical shines brightly in the field of mobile wearable monitoring.
