Kairui Medical Launches Ultra-High-Precision Sub-Millimeter Blood Collection Robot to Address Venipuncture Challenges Across All Age Groups

Vascular puncture, as an indispensable and critical technique in clinical diagnosis and treatment, is widely applied and frequently performed. Statistics show that China’s healthcare sector consumes 15 billion disposable syringes and 13 billion infusion sets annually, with approximately 70% of medical decisions relying on blood diagnostic test results.

However, due to the difficulty of certain vascular puncture procedures, nurses may fail to accurately cannulate the vessels. Frontline clinical healthcare workers constantly face challenges in performing punctures on difficult vessels, leading to occasional doctor-patient disputes.

On one hand, for specific groups such as children, the elderly, and critically ill patients, the difficulty of venipuncture is significantly increased due to their physiological characteristics or clinical conditions. Survey data indicate that approximately 27% of patients in clinical settings have poorly visible veins, with 40% of these cases being unidentifiable by visual inspection; consequently, the first-attempt success rate for nurses performing venipuncture is less than 86%. On the other hand, vascular access procedures are widely applied. With population aging and a declining number of young nursing professionals, frontline clinical healthcare workers face increasingly substantial workloads.

In response to the aforementioned issues,Chengdu Kairui Medical Technology Co., Ltd. Aixam(hereinafter referred to as “Kerry Medical”)Built on robotics technology, with AI data serving as the connecting link,Successfully built an intelligent ecosystem platform for sample collection, diagnosis, and rehabilitation that integrates early detection, early treatment, and early recovery, aiming toHospitals, Clinics, Mobile Blood Collection Vehicles, Health Examination Centersand other application scenarios,Provides precise intelligent blood collection, AI-powered blood diagnostics, intelligent ultrasound scanning, and AI-based ultrasound imaging diagnostics.a series of solutions with broad applicability and low cost, driving the efficiency and intelligence of healthcare services.

As a critical tool in clinical diagnosis and treatment, Kerry Medical’s solutions are of significant importance for enhancing the accuracy and efficiency of vascular puncture, improving patient experience, and reducing doctor-patient disputes.

“As a fully automated surgical device, the intravenous puncture robot features automatic disinfection and puncture capabilities, significantly reducing direct contact between healthcare workers and patients, thereby lowering the risk of cross-infection. Furthermore, its superior imaging technology, precise recognition capabilities, operational stability, and efficient, streamlined workflow will help address common challenges in traditional intravenous puncture, such as low success rates and frequent complications,” stated the founder of Kerry Medical.

Despite the significant value of automated needle insertion and the fact that the concept has long been proposed, achieving technological breakthroughs and facilitating the practical deployment of related devices is by no means easy. For instance, the vascular diameter in neonates or premature infants can be as small as 0.5 mm. In such cases, performing precise puncture on vessels with a diameter of 0.5 mm imposes extremely stringent requirements on optical and mechanical technologies. The primary technical challenges currently faced include leveraging imaging modalities such as optics and acoustics to accurately localize the spatial position of the target site, while ensuring precise motion control of the mechanical components, thereby achieving both visibility and verifiability.

As significant progress in core technologies has only been achieved in recent years, only a few institutions worldwide have successfully developed proof-of-concept prototypes, with Kerry Medical being one of them. Based on an in-depth analysis of clinical needs and the resolution of key technical challenges, Kerry Medical has achieved further breakthroughs in core technologies such as vein recognition and feedback, autonomous decision-making, three-axis concentric mechanism design, and control methods. The company has deeply integrated and innovatively applied cutting-edge technologies, including photoacoustic vision, artificial intelligence, six-dimensional force sensing, and nine-axis flexible control, while also combining precise 3D vascular localization algorithms with ultrasound-based vascular detection and trajectory planning algorithms.Pioneering Photoacoustic-Mechanical Multimodal Intelligent Sensing Puncture Robot——Dinghai Shenzhen Series Intelligent Blood Collection Robot.

Having established a robust technological foundation, Kerry Medical has actively forged partnerships with authoritative institutions such as West China Hospital of Sichuan University, Sichuan Provincial Hospital for Women and Children, and Tongji University. By integrating clinical scenarios, the company continuously enhances its technical capabilities while simultaneously expanding its product pipeline to meet broader clinical needs.

It is reported that Kerry Medical is actively seeking financing to further advance the parallel research and development of multiple products, thereby providing the healthcare industry with more innovative and efficient solutions.

As the global population ages, the number of patients with chronic diseases increases, and medical technology continues to advance, the demand for precise and efficient vascular access techniques is growing.

“According to statistics from the Society of Hospital Medicine, approximately 1.4 billion venous blood draws are performed annually in the United States. Based on a population ratio of roughly 4.3 times between China and the U.S., it is estimated that China conducts over 16 million venous blood draws per day. Assuming that automated phlebotomy robots operate at a speed comparable to the average efficiency of nurses—120 draws per day—the total domestic market demand would be approximately 140,000 units. With an estimated unit price of RMB 600,000, the market size for phlebotomy robots in China exceeds RMB 80 billion,” stated the founder of Kairui Medical.

The healthcare sector demands products that are more closely aligned with contemporary needs, and vascular access robots undoubtedly offer extensive application prospects and a robust product lifecycle. As an enterprise deeply committed to technological innovation and dedicated to developing comprehensive solutions that closely address actual clinical requirements, Kerry Medical will continue to iterate its product pipeline, fully leverage the potential of big data analytics and intelligent devices, and deliver more high-value solutions to the industry.
