Device for protecting a syringe, in particular for a syringe used for injecting radioactive product (s)
First Claim
1. A protection device for a syringe used for injection of radioactive product(s), comprising:
- an envelope of radioprotective material, the envelope shaped to cover a cylindrical body of a syringe, the syringe further including a needle, a reception cone, a piston, the piston including a stem with a head,an opening fitted at a front end of the envelope, the opening for letting through the needle or the reception cone, andanother opening at a rear end of the envelope for insertion and withdrawal of the syringe, as well as for operating the stem, anda structure of radioprotective material associated with the envelope, the structure forming a protective shield at least partially facing the another opening at the rear end of the envelope, while enabling the operation of the piston, wherein,the protective shield has the general form of a tubular jacket fitted with a bottom,said jacket covers the another opening at the rear end of the protective envelope,said jacket comprises interconnection means removable with respect to the stem, andthe removable interconnection means comprises a lock arranged to press the head of the operating stem against an internal face of the bottom of said jacket.

Abstract
A syringe protecting device includes a casing (9) made of a material protecting against radiation, adapted to cover the syringe cylindrical body (3), which casing (9) is associated with a structure (10) likewise made of a material protecting against radiation, designed to form at least a partial protective shield on the rear end of the syringe, while allowing the syringe plunger (4) to be operated. In one particular embodiment, the protective shield is globally shaped like a cylindrical sleeve (10) provided with a base (18); the sleeve (10) is mounted sliding on the protective casing (9) by capping it through its rear end, and it comprises mechanism (20) for being removably secured to the stem (5) operating the syringe plunger (4).
