The HTSY® dual syringe Angiographic Injector is a dual-channel fully automatic angiographic injection device specially developed by Tianjin HanTeng Shengye Technology Co., Ltd. for CT enhanced scanning. Different from the single-tube model, this machine adopts a dual-tube independent pump injection structure, which can separately load contrast agent and normal saline, achieving automatic angiography + trailing flushing, staged injection, and delayed balanced infusion. It is a standard equipment for high-frequency CT enhanced examinations in hospitals, imaging centers, and health examination buildings. Global customers are welcome to inquire about and cooperate.
The HTSY® dual syringe Angiographic Injector is specifically designed for CT image enhancement diagnosis. The two syringes can independently set parameters without interfering with each other, and can complete common clinical procedures such as contrast agent injection, physiological saline trailing flushing, delayed injection in multiple doses, and balanced fluid replacement.
The equipment supports enhanced CT scans of all body parts. The dual-tube structure can automatically complete drug administration and flushing during a single scan process, eliminating the need for manual needle replacement and reducing the need for repositioning, significantly improving the examination efficiency of a large number of patients undergoing enhanced CT in both general practice and outpatient settings.
The system features a high-definition touch control interface, supporting the storage of standardized enhanced protocols for multiple body parts and one-click invocation; it also supports synchronous signal linkage with the CT host, accurately matching the scanning sequence. In addition, the equipment is equipped with an intelligent safety monitoring system, which ensures the stable operation of the high-pressure injection process throughout the process and safeguards the safety of patients.

The HTSY® dual syringe Angiographic Injector features independent control for each tube, with one tube for contrast agent and the other for normal saline. It enables the standard CTA clinical process of contrast injection + automatic follow-up flushing. This effectively improves the filling degree of contrast agent within blood vessels, extends the optimal scanning window period, and significantly enhances the clarity of fine blood vessels in coronary arteries and cerebral vessels, making it an essential equipment for high-end CT vascular imaging.
The dual-syringe Angiographic Injector of HTSY® allows independent editing of flow rate, dose, pressure and delay time for each channel. It supports complex modes such as high and low speed segmented injection, balanced fluid replacement, and delayed scanning injection. It can perfectly match individualized injection plans for different blood vessels and patients of different weights, resulting in uniform imaging, fewer artifacts, and stronger vascular continuity.
Compared with single-tube equipment, this double-tube high-pressure injector eliminates the need for frequent cylinder changes, exhaust, and material preparation. It can continuously handle multiple enhanced patients, significantly increasing the daily examination throughput of the CT room and fully meeting high-load working scenarios such as hospital peak periods and concentrated screening during physical examinations.
The HTSY® dual syringe Angiographic Injector features multiple safety-protecting functions such as dual overpressure protection, segmented pressure monitoring, and abnormal shutdown. These features can effectively prevent various safety hazards such as contrast agent leakage and air embolism, ensuring the safety of patients.
The equipment is equipped with a standard CT synchronization trigger interface, which is compatible with all major domestic and foreign spiral CT models. The consumables use universal disposable double-tube high-pressure syringes, eliminating monopolized consumables and making procurement convenient. The overall structure is modularized, resulting in low failure rate, stable heat dissipation, and resistance to high-frequency continuous operation. This makes the long-term usage cost of the hospital lower.
