Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure injectors, and in particular to a wireless connection device for high-pressure injectors based on Star Flash technology. Background Art

[0002] High-pressure injectors are devices used to inject contrast agents and saline during CT / MR / angiography imaging. The injection pump host and control panel of the mainstream high-pressure injectors on the market are connected to transmit signals via cables. Since the imaging room and the doctor's operating room are separated by lead or copper protective walls and protective glass, when installing or replacing high-pressure injector equipment in the later stage, it is necessary to destroy the wiring pipes for wiring, which will inevitably damage the protective isolation layer of the protective wall, causing radiation leakage risks and posing a health hazard to medical staff.

[0003] Regarding the above question, although wireless high-pressure injectors are available on the market, most utilize Bluetooth or Wi-Fi. However, these two technologies are susceptible to signal shielding in environments such as hospital CT rooms, MRI rooms, and catheterization labs, which require protective isolation walls. This can lead to frequent signal interruptions, delays, or failures, impacting the stable use of high-pressure injectors. For example, Bluetooth has a limited coverage range, slow transmission speeds, and weak anti-interference capabilities; while Wi-Fi consumes a lot of power, has a long latency, is insecure, has poor transmission stability, and cannot achieve precise positioning.

[0004] Therefore, SparkLink, an emerging wireless short-range communication technology, has emerged. As a next-generation short-range wireless connection technology native to China, it comprehensively innovates and upgrades traditional technologies like Bluetooth and Wi-Fi. It not only significantly improves speed but also achieves significant breakthroughs in latency, transmission distance, security, and reliability, meeting the high-quality short-range wireless connection requirements of medical devices.

[0005] Star Flash technology utilizes two modes, SLB and SLE, enabling coexistence with Wi-Fi and Bluetooth protocols, effectively addressing current industry pain points and application challenges. The SLB technology, benchmarked against Wi-Fi, supports 20μs one-way latency, 99.999% transmission reliability, and 1μs synchronization accuracy, addressing high-speed, high-volume, and high-quality connection scenarios. The SLE technology, benchmarked against Bluetooth, supports 250μs two-way interaction, receiver sensitivity as low as -110dBm, and concurrent access for up to 256 users, meeting the needs of low-power, lightweight connections. Summary of the Invention
