Abstract
The present invention relates to a radiation-protection device (1) intended to be fitted onto a syringe used for injecting a radioactive product. This radiation-protection device (1) comprises a tubular radiation-protection structure (11) equipped with a lateral housing (118) to accommodate a shield (12) made from a transparent radiation-protection material. One of the ends (121) of the shield (12) made of transparent radiation-protection material comprises a tenon structure (14a) designed to engage with a complementary mortise structure (14b) formed in said lateral housing (118); and a retractable locking member (14c) is designed to engage with another end (122) of said shield (12) made of transparent radiation-protection material, in order to lock said shield in position.

A radiation-protection device (1) intended to be fitted onto a syringe (2) used for injecting a radioactive product, said syringe (2) comprising a cylindrical syringe body (3) having a front end (5) provided with a liquid suction and ejection hole (6) and a rear end (7) provided with an opening (9) into which is inserted a syringe plunger (8),
- said radiation-protection device (1) comprising:
- (i) a tubular radiation-protection structure (11), with a longitudinal axis (X), made at least partially of a radiation-protection material, said tubular radiation-protection structure (11) comprising—an inner surface (111) delimiting a central housing (112) adapted to receive at least part of said syringe body (3),—an outer surface (113),—a front opening (114) through which said front end (5) of said syringe body (3) is intended to emerge,—a rear opening (115) adapted for inserting and extracting said syringe body (3), and for operating said syringe plunger (8),—a side opening (116) that opens into said central housing (112), said side opening (116) comprising a rebate structure (117) and forming a side housing (118),
- (ii) a shield (12) made of a transparent radiation-protection material, added into said side housing (118) and positioned in rest on said rebate structure (117), said radiation-protection device (1) also comprising locking means (14) to lock said shield (12) of transparent radiation-protection material in said side housing (118), wherein said locking means (14) comprise
- a tenon structure (14a) arranged at one end (121) of said shield (12) of transparent radiation-protection material, adapted to cooperate with a complementary mortise structure (14b) arranged in said side housing (118), and
- a retractable locking member (14c) adapted to cooperate with another end (122) of said shield (12) of transparent radiation-protection material, said locking member (14c) being able to be activated to lock said shield (12) of transparent radiation-protection material in position after introduction of said tenon structure (14a) into said mortise structure (14b), and to be deactivated to allow said shield (12) of radiation-protection material and said tubular radiation-protection structure (11) to be separated from each other.
