Against the backdrop of an accelerating global aging population, a rising demand for chronic disease management, and the awakening of personal health awareness, home medical devices are transforming from “medical assistive tools” to “core carriers of health management”. According to Grand View Research, the global market size of home medical devices exceeded 300 billion US dollars in 2024, with a compound annual growth rate remaining above 8.5%. In this field, there is an enterprise that has been committed to the mission of “protecting family health” since 2002, deeply engaged in the research and development, production and service of electronic medical products for family care. It is Sejoy – a high-tech enterprise driven by “leading technology, quality first, advanced management and excellent service”. For over two decades, Sejoy has developed into a significant player in the global home medical equipment field, thanks to its dedication to technological innovation, commitment to product quality, and insight into customer needs. Its products cover chronic disease monitoring such as blood sugar, uric acid, and blood lipids, and extend to diverse scenarios including women’s health and infectious disease screening. With the slogan “Professional medical-grade testing The “convenient home experience” has redefined the boundaries of family health management.
I. Starting from the Original Aspiration: 20 years of deep cultivation, anchoring the development direction with concepts
In 2002, when the Chinese medical equipment market was still dominated by large-scale equipment for hospitals, Sejoy had already keenly captured the trend of “health management going down to the grassroots” – as living standards improved, people’s demand for disease prevention and daily monitoring became increasingly urgent, while the traditional medical institution’s testing model had pain points such as high time cost and limited frequency. It is precisely based on this insight that Sejoy has positioned itself as “focusing on electronic medical products for home care” since its establishment, with the corporate vision of “bringing professional medical testing into ordinary households”.
For over two decades, Sejoy’s development trajectory has been deeply intertwined with its business philosophy of “leading technology, quality first, advanced management, and excellent service”. This sixteen-character guideline is not an abstract slogan but runs through every aspect of the company’s operation: “Leading technology” is the engine driving innovation, requiring the R&D team to always stay at the forefront of industry technology. “Quality first” is the cornerstone of survival. From raw material procurement to finished product delivery, a full-chain quality control system should be established. “Advanced management” is the guarantee of efficiency, reducing costs and enhancing response speed through refined management. “Service excellence” is the bond connecting customers, providing professional services to address users’ pain points during usage. It is precisely this commitment to the concept that has enabled Sejoy to gain a firm foothold in the home medical equipment market and gradually transform from a “product provider” to a “health solution service provider”.
Ii. Product Matrix: Covering the entire life cycle, building a family health monitoring network
As a professional supplier of electronic medical products for home care, Sejoy’s core competitiveness is first reflected in its rich and precise product line. Centering on the core scenario of “home health monitoring”, the company has built a diversified product matrix covering chronic disease management, routine health screening, and the needs of specific groups, enabling users of different ages and with different health needs to find suitable detection tools.
(1) Chronic disease Management: Provide precise data support for “long-term chronic disease management”
In the field of chronic disease management, Sejoy’s product system focuses on the monitoring of core indicators for metabolic diseases, including blood glucose monitoring systems, uric acid monitoring systems, lipid monitoring systems, etc. Take the blood glucose monitoring system as an example. This product adopts advanced electrochemical sensing technology. It only requires a trace blood sample (less than 0.5μL) to obtain the result within 5 seconds, and the detection error is controlled within ±15%, meeting the international clinical laboratory standards. Considering the characteristic that diabetic patients need high-frequency monitoring, the device design takes into account both portability and ease of operation – the no-code adjustment function reduces operation steps, the large screen display and voice broadcast are suitable for elderly users, and the accompanying mobile phone APP can automatically record the detection data and generate trend charts, helping users and doctors intuitively understand the blood sugar fluctuation patterns.
The uric acid and lipid monitoring system continues this design concept: The uric acid monitoring system is designed for patients with hyperuricemia and gout, enabling rapid detection of blood uric acid. The lipid monitoring system can simultaneously test and calculate Total Cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and Total Cholesterol/HDL
The five key indicators of Cholesterol provide data support for the risk assessment of cardiovascular diseases. The common feature of such products is “medical-grade precision + home-grade convenience”, allowing patients with chronic diseases to monitor their daily conditions without frequently traveling to the hospital, effectively reducing the risk of complications.
(2) Routine health and Specific Population Testing: Expanding the boundaries of family health management
In addition to chronic disease management, Sejoy’s product line has also extended to a wider range of health screening scenarios. The hemoglobin monitoring system is suitable for anemia screening, especially for pregnant women, children and the elderly. The urine analysis system, through dry chemical test strips technology, can quickly detect 11 indicators such as urine sugar, urine protein, and white blood cells, assisting in the early detection of urinary system diseases and diabetic complications.
In response to the health needs of women, Sejoy has developed a series of female health care testing products, including ovulation test strips and early pregnancy test strips. These products adopt highly sensitive immunochromatography technology, with an accuracy rate of over 99%. They are easy to operate and offer clear result interpretation, providing convenient tools for female reproductive health management. In addition, in the field of public health, the company’s drug abuse detection and infectious disease detection products also play a significant role – drug abuse detection test strips can quickly screen for common drug components such as morphine and methamphetamine, and are suitable for scenarios such as enterprise pre-employment physical examinations and monitoring in drug rehabilitation institutions. The infectious disease detection products cover the detection of pathogens such as influenza, the novel coronavirus, and hepatitis B. They use colloidal gold immunochromatography technology and can provide results within 15 minutes, offering support for epidemic prevention and control as well as the early detection of infectious diseases.
(3) Product Design: Centered on users, create an “accessible” usage experience
The product design of Sejoy always adheres to the principle of “user orientation”. Whether it is the hardware appearance or the software functions, they all fully take into account the actual scenarios of home use: The device shell is made of anti-slip material, and the corners are rounded to avoid bumps. The key layout conforms to ergonomics, and the large-sized keys reduce accidental touches. Some products support Bluetooth connection, and data can be synchronized to the family doctor terminal, achieving a closed-loop management of “user – device – doctor”. This attention to detail has transformed professional medical testing equipment from “cold instruments” into reliable “family health partners” for users.
Iii. Technology Research and Development: Three major platforms drive innovation and build a solid core technology barrier
Sejoy is well aware that in the field of medical equipment, technology is an irreplaceable core competitiveness. For over two decades, the company has consistently regarded R&D investment as a strategic priority. Relying on its “technical personnel advantage”, it has formed a research and development team led by doctors and masters, and established three core technology R&D platforms: electrochemistry, dry biochemistry, and immunochromatography, providing continuous impetus for product innovation.
(1) Electrochemical Technology Platform: Precise sensing, leading the revolution of Point-of-care Testing (POCT)
Electrochemical technology is Sejoy’s “signature skill” in chronic disease monitoring products. This platform is based on working electrodes modified by nanomaterials and achieves quantitative analysis of target substances by detecting the current signals generated by biochemical reactions. The R&D team has been continuously making breakthroughs in electrode materials, electrolyte formulas, reaction membrane processes and other aspects. Currently, they have achieved high-sensitivity detection of various small molecule substances such as glucose, uric acid and cholesterol. For instance, in the research and development of blood glucose sensors, the team adopted a “multi-layer membrane structure” design – the bottom layer is a conductive layer, the middle layer is an enzyme reaction layer (fixing glucose oxidase), and the surface layer is an anti-interference membrane. This effectively eliminates the interference of other reducing substances in the blood (such as vitamin C and uric acid) on the detection results, increasing the stability of the sensor in a whole blood environment by more than 30%.
(2) Dry Biochemical technology Platform: Fast and convenient, promoting the integration of “sample to result”
The dry biochemical technology platform is mainly applied to the combined detection of multiple indicators such as blood lipid and liver function. Unlike traditional wet biochemical tests that require large instruments and complex operations, dry biochemical test strips pre-fix all reaction reagents on the carrier. Only a drop of blood sample is needed to initiate the reaction, and the results can be read by reflectivity. Sejoy’s dry biochemical platform adopts microfluidic technology to optimize sample distribution, ensuring that reagents and samples react fully. Meanwhile, it guarantees stable reaction conditions through a constant temperature control module (37℃±0.5℃), reducing the detection time to within 3 minutes. It can also simultaneously test multiple indicators, meeting the “one-stop” health screening needs of families.
(3) Immunochromatography technology platform: High specificity, empowering the detection of infectious diseases and markers
The immunochromatography technology platform focuses on the rapid detection of macromolecular substances (such as antigens, antibodies, and hormones), and serves as the core technical support for women’s health care testing and infectious disease testing products. This platform is based on the principle of specific antigen-antibody binding and realizes visual or quantitative detection through markers such as colloidal gold and fluorescent microspheres. The R&D team has made breakthroughs in the screening of chromatography membrane materials, the optimization of labeling processes, and signal amplification technology, enabling the product’s detection sensitivity to reach the pg/mL level and with a cross-reaction rate below 1%. Take the early pregnancy test strip as an example. It can accurately detect pregnancy within 7 days after conception (when the HCG concentration is ≥25mIU/mL), and its sensitivity far exceeds the industry average.
The coordinated development of the three major technology platforms not only supports the performance leadership of existing products but also enables Sejoy to have the ability to respond quickly to market demands. According to statistics, the company’s annual R&D investment accounts for more than 8% of its revenue. It has applied for over 100 patents, including more than 30 invention patents. The rate of technology transfer exceeds 80%, truly achieving an innovative rhythm of “developing one generation, reserving one generation, and industrializing one generation”.
Iv. Quality and Compliance: Guided by international standards, we forge the belief of “zero defect” products
The quality of medical equipment is directly related to the health and even life safety of users. Sejoy integrates the concept of “quality first” throughout the entire product life cycle. Through a strict quality management system and international compliance certification, it ensures that every device meets the highest safety standards.
(1) Full-process quality control: A closed loop of quality control from “source” to “terminal”
Sejoy has established a full-process quality control system covering “R&D and design – raw material procurement – production and manufacturing – finished product inspection – after-sales service”. During the R&D stage, the product needs to pass more than several reliability tests to simulate the impact of environmental factors such as extreme temperatures (-20℃ to 60℃), humidity (10% to 95%RH), and vibration on performance. In the raw material procurement process, the company conducts strict access reviews on suppliers. Key components (such as sensors and chips) all come from internationally renowned brands, and material certificates and performance test reports must be provided. The production and manufacturing adopt automated production lines, equipped with online detection devices, to conduct real-time monitoring of each process, and automatically remove non-conforming products. Finished product inspection is carried out in accordance with the principle of “individual inspection + sampling retesting” to ensure that the qualification rate of products leaving the factory reaches 100%.
(2) International authoritative certification: Benchmarking against the world’s highest standards, opening up global market channels
To ensure the international recognition of its products, all Sejoy products have passed strict compliance certifications. Among them, the ISO 13485 medical Device quality management system certification is the foundation. This certification covers the entire process from design, development, production, installation to service, and requires enterprises to establish a quality management mechanism for continuous improvement. The European CE certification and the US FDA certification are the “passes” for products to enter the European and American markets. The CE certification requires passing strict performance tests and clinical evaluations to prove that the product complies with the requirements of the EU’s Medical Device Regulation (MDR). FDA certification requires the submission of detailed technical documents and clinical data. Approval can only be granted after on-site review by FDA officials (if applicable). At present, Sejoy’s core products such as blood glucose monitoring systems and uric acid monitoring systems have passed CE and FDA certifications, making it one of the few Chinese home medical equipment enterprises to simultaneously enter the mainstream markets of Europe and America.
V. Market and Services: Centered on customers, build a global value network

In overseas markets, the company’s products have been exported to over 130 countries and regions including Europe, North America, Southeast Asia and the Middle East, and it has established long-term cooperative relationships with local medical device distributors, chain pharmacies and e-commerce platforms.
(2) Full-cycle customer Service: From “Product Delivery” to “Health Companionship”
Sejoy extends the concept of “excellent service” to every touchpoint of customer contact, and has established a full-cycle service system of “pre-sale consultation – in-sale guidance – after-sale support”. Before sale, a professional customer service team provides product selection suggestions to customers and recommends suitable devices based on users’ health needs. During the sales process, users are guided to operate through video tutorials, graphic manuals and other means to ensure correct usage. After-sales service: A 24-hour service hotline and online customer service are set up to respond quickly to needs such as maintenance and calibration.
(3) Cost Advantage: By enhancing scale and efficiency, high-quality medical equipment becomes “within easy reach”.
Under the premise of ensuring quality, Sejoy has formed a significant cost advantage through large-scale production, supply chain optimization and management efficiency improvement. The company reduces the cost of raw materials through large-scale procurement. By adopting the lean production model and optimizing the production process, the per capita production efficiency has increased by 40%. The digital management system realizes the full visibility of the supply chain and increases the inventory turnover rate by 25%. These measures have enabled Sejoy’s products to be priced 20% to 30% lower than international brands at the same quality level, truly achieving the “universalization of high-quality medical equipment” and making professional health monitoring tools affordable for more families.
Vi. Industry Contribution and Future Outlook: Safeguarding Health through Innovation and Empowering the future with Technology
