Radionuclide projectile injection device

Abstract

The invention discloses and provides a radionuclide pill injection device, which comprises an injection assembly, a pill injection assembly, a pill injection assembly, a pill injection assembly and a pill injection assembly, a liquid outlet of the auxiliary injector is communicated with a liquid outlet of the main injector through a connecting pipe; the auxiliary pushing mechanism comprises a control box, a first pushing assembly and a second pushing and injecting assembly, and the first pushing assembly and the second pushing and injecting assembly are electrically connected with a microcontroller in the control box; the first pushing assembly is clamped to a first pushing handle of the injector and used for pushing and injecting pills in the injector into the body. The pushing assembly II is clamped at a pushing handle II of the auxiliary injector; and the normal saline in the auxiliary injector is pushed into the needle head of the main injector. The invention provides a radionuclide projectile injection device. The radionuclide projectile injection device is provided with an injection assembly and an auxiliary pushing mechanism; the purpose of rapid injection can be achieved according to injection requirements, and meanwhile the problem of medicine residues is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radionuclide pellet injection device. Background technique [0002] Nuclear medicine is an emerging discipline that uses nuclear techniques to diagnose, treat and study diseases. It is the product of the combination of modern science and technology such as nuclear technology, electronic technology, computer technology, chemistry, physics and biology and medicine. Nuclear medicine can be divided into two categories, namely clinical nuclear medicine and basic nuclear medicine or experimental nuclear medicine. In medicine, radioisotopes and nuclear radiation can be used for diagnosis, treatment and medical scientific research; in pharmacy, they can be used for research on the principle of drug action, determination of drug activity, drug analysis and radiation disinfection of drugs, etc. [0003] Imaging agent injection techniques commonly used in nuclear medicine examin...

AI Technical Summary

Problems solved by technology

[0004] 1. However, the current bolus injection is mainly completed by manual operation by medical staff, and it is difficult to achieve the speed of bolus injection by manual injection, so it is impossible to meet the requirements of bolus injection;

[0005] 2. During the nuclear medicine examination, due to the remaining part of the drug at the front end of the needle and syringe, the amount of drug actually entering the human body is less than the marked amount. Moreover, when many radioactive drugs are injected into the human body, a bolus injection is required. However, the existing Needles and syringes are not enough to meet people's needs;
