DSA High Pressure Contrast Injector

HTSY®DSA High Pressure Contrast Injector is a dedicated high-precision injection system specifically developed for interventional surgery scenarios. Unlike conventional imaging contrast devices, it is designed to meet the intraoperative dynamic imaging requirements of DSA (Digital Subtraction Angiography) surgeries. It is widely used in minimally invasive diagnostic surgeries such as cardiac intervention, neurointervention, vascular surgery, and tumor intervention. This equipment is equipped with a medical-grade high-stability power output system, supporting multiple intraoperative exclusive modes such as continuous stable pressure injection, phased supplementation, low-pressure fine adjustment, and high-pressure rapid imaging. It can adapt to personalized surgical contrast imaging needs for different vascular diameters and different lesion severities. The entire system supports long-term continuous operation during the surgery and is compatible with the high-intensity, high-precision, and high-safety diagnostic standards of the operating room. It is a necessary core equipment for the standardized construction of hospital interventional departments.

Product Features

1. The DSA-exclusive stable-pressure injection is specially optimized for dynamic intraoperative imaging.

The HTSY®DSA High Pressure Contrast Injector, designed specifically for DSA's dynamic subtraction imaging characteristics, eliminates the conventional CT device's instantaneous injection logic and supports long-term stable-pressure and uniform-speed injection during the operation. It can maintain the continuous and uniform filling of the contrast agent in the blood vessels, perfectly meeting the requirements of DSA's continuous dynamic acquisition images. It effectively avoids problems such as vascular imaging discontinuity, blurred edges, and non-visualization of peripheral areas during interventional surgeries, and can clearly present the details of vascular stenosis, deformity, aneurysms, and the blood supply vessels of the lesion, providing clear dynamic image support for doctors' precise judgment and precise surgical operations during the procedure.

2. The intraoperative dynamic parameters can be adjusted, suitable for complex interventional surgeries.

This high pressure injector is equipped with an exclusive intelligent control system for interventional surgeries, supporting real-time adjustment of flow rate, pressure, and injection dose throughout the surgery without the need to stop and restart the program. For patients with high-risk blood vessels, narrowed blood vessels, or fragile blood vessels, a flexible injection mode of low-pressure start, uniform increment, and stable pressure maintenance can be achieved, avoiding vascular damage and the risk of contrast agent leakage caused by sudden high-pressure impact. It also supports intraoperative micro-dose supplementation and phased delayed injection, suitable for the personalized contrast imaging needs of complex and difficult interventional surgeries, with extremely strong clinical adaptability.

3. The equipment is deeply linked and synchronized, ensuring zero delay in surgical imaging.

The HTSY®DSA High Pressure Contrast Injector is equipped with a DSA-specific synchronous communication module, which can be linked with the contrast imaging host, fluoroscopy system, and image acquisition system in real time, achieving millisecond-level synchronization of injection initiation, liquid filling, and image acquisition. It completely solves the problem of time sequence disconnection between traditional injection equipment and DSA equipment, resulting in blank frames in the early stage and overexposed frames in the later stage, ensuring the complete and continuous integrity of each dynamic vascular image, significantly improving the diagnostic accuracy and operational efficiency of the surgery, and reducing the time spent on intraoperative contrast imaging.

4. Surgical-level multiple safety protections, safeguarding intraoperative diagnosis safety.

Based on the high-risk scenarios of interventional surgeries, a comprehensive safety system is created for DSA. The DSA high pressure injector has multiple protection functions such as real-time pressure monitoring during the surgery, pipe loosening warning, micro-bubble identification, overload automatic pressure relief, and emergency one-button shutdown. The equipment can intelligently identify changes in vascular resistance and automatically reduce pressure and shut down when encountering vascular spasms or sudden increase in resistance, avoiding vascular damage. It also comes with multi-level audible and visual warnings during the operation, real-time alerts for abnormal conditions, minimizing the diagnostic risks of interventional surgeries at the equipment level.

5. Specialized body design for the operating room, durable and easy to maintain

The entire HTSY®DSA High Pressure Contrast Injector body is made of medical antibacterial and corrosion-resistant materials, suitable for the high-temperature disinfection and frequent cleaning environment of the operating room, resistant to drug liquid corrosion and wear and tear, with a longer equipment lifespan. The operation interface is optimized for quick operation during the surgery, with core parameters clearly displayed, supporting dual control modes of foot pedal and touch screen, suitable for surgical aseptic operation norms. The equipment comes with a built-in surgery case storage and intraoperative parameter recording function, facilitating postoperative case review, department quality control management, and equipment maintenance calibration, perfectly adapting to the standardized, standardized, and intelligent clinical use scenarios of interventional surgery rooms.
