Description

Technical Field

[0001] This invention relates to the field of nuclear medicine equipment consumables technology, and in particular to a dispensing and injection consumable for injecting radioactive tracers. Background Technology

[0002] Radioactive tracers, also known as "radioactive indicators," commonly use carbon-14 (carbon-14). 14 C), Phosphorus 32 ( 32 P), sulfur 35 ( 35 S), Iodine-131 ( 131 I), hydrogen 3( 3 H) Radioactive isotopes are widely used in biochemical reactions to trace pathways. Radioactive tracers can also be used to track distribution in natural systems, such as cells or tissues. Radioactive tracers form the basis of various imaging systems, such as positron emission tomography (PET), single-photon emission computed tomography (SPECT, or SPET), and Technetium scanning. Clinically, radioactive tracers are used as a special class of pharmaceutical reagents containing radioactive nuclides, emitting penetrating radiation. Therefore, when handling radioactive tracers manually—opening, diluting, and dispensing them—workers must exercise extreme caution and wear protective clothing such as gowns, masks, caps, rubber gloves, and safety goggles; otherwise, it could pose a safety hazard to medical personnel.

[0003] In order to develop an automated drug dispensing system, it is necessary to equip the system with dispensing consumables that can be used and replaced to meet the usage requirements of the automated drug dispensing system and enable the drug dispensing to be carried out effectively.

[0004] Based on this, this application develops a consumable for injecting radioactive tracers to be used in conjunction with an automated drug dispensing system. This consumable makes the system easy and convenient to use, install, and replace, meeting the clinical needs of tracer dispensing, reducing the workload of medical staff, and improving safety. Summary of the Invention
