Description of Integrated Injection Protective Table

The integrated injection protective table—commonly known in the industry as the "bull-head injection window"—is a critical piece of specialized equipment used for the injection and administration of radiopharmaceuticals in nuclear medicine and radiotherapy departments. This unit integrates high-lead-equivalent radiation shielding, an ergonomic operating interface, sterile environment control, intelligent lighting, and an integrated patient-staff intercom system; it is designed to provide healthcare professionals with the highest level of occupational radiation protection while ensuring the safety and efficiency of the patient administration process. Serving as the primary protective barrier during the phase of daily nuclear medicine operations involving the most frequent handling of high-activity radionuclides (such as F-18, I-131, and Tc-99m), the station utilizes a partitioned operation design to physically separate staff from radiation sources. Capable of reducing radiation exposure risk by over 90%, it constitutes essential infrastructure for meeting national environmental protection standards and the acceptance criteria set by health authorities.

Features of Integrated Injection Protective Table

Ultra-high Protection Level: Designed for F-18 (511 keV, common in PET-CT) and I-131 (364 keV, used in therapy), the main unit offers a lead equivalence of ≥50 mm Pb, while the standard SPECT injection area provides ≥40 mm Pb.

Zero Direct Exposure: Utilizes a partitioned operation mode where the patient extends their arm through an external opening while the medical staff operate from within. Hands, torso, and head remain shielded throughout the process, ensuring a dose rate of ≤0.1 μSv/h at 30 cm from the outer surface and ≤0.05 μSv/h at hand ports or door gaps.

Premium Materials: Constructed from 304/316L medical-grade stainless steel (thickness ≥1.5 mm) featuring seamless welding, rounded corners, and an anti-fingerprint finish, the material is resistant to acid and alkali corrosion, easy to disinfect, and prevents dirt accumulation.

Sealed Structure: The front curved opening (bull-nose design) is equipped with double-layer silicone seals and detachable lead-rubber sleeves to effectively prevent the spread of radioactive aerosols.

High-Definition Viewing Window: Features ZF7/ZF5 high-lead glass (density ≥5.0 g/cm³) with lead equivalence matching the main unit; offers ≥85% light transmission, is distortion-free and aging-resistant, ensuring a clear field of view.

Storage and Waste Disposal: Includes a lead-shielded storage cabinet at the base (25 mm Pb equivalent) for consumables such as syringes; a waste disposal port on the countertop connects directly to a waste bin below, ensuring safe, enclosed waste handling.
