Description

Technical Field

[0001] This utility model relates to the field of radiation protection equipment, and in particular to a syringe protective canister. Background Technology

[0002] The three main parts of a conventional syringe protective canister are connected by a threaded structure: the canister body, a head protective cap movably connected to the front of the canister body, and a tail protective cap movably connected to the rear of the canister body. During drug dispensing, after placing the syringe containing the radioactive drug into the protective canister body, the dispensing personnel need to tighten the head and body of the protective canister to prevent it from falling out during use. Conversely, after receiving the canister containing the radioactive drug syringe, the injection personnel need to loosen the various parts of the protective canister to expose the syringe for administering the radioactive drug to the patient.

[0003] Protective canisters are mostly made of tungsten alloys, which are heavy and not very hard. Therefore, repeated tightening and loosening during use can cause irreparable damage to the threads, such as thread breakage and chipping. This can result in parts of the canister being unable to be tightened properly or a lengthy tightening and loosening process. Consequently, this leads to: 1. Increased radiation exposure time for users; 2. A safety hazard of falling and injuring users; 3. Increased costs for the user due to irreparable thread damage.

[0004] Based on this, this application designs a syringe protective canister that incorporates a smooth pin structure and a lead screw structure as connection methods to solve the above problems. Utility Model Content
