Embodiment Construction

[0035] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0036] A: Power and stroke control part

[0037] Part 1: This part is the power compression and lifting part of the product, including standard motor, lead screw 29, lead screw slider 30, photoelectric touch panel 31, and syringe pressing sheet 33.

[0038] The standard motor controls the rotation of the lead screw 29, which drives the lead screw slider 30 to move up and down. The photoelectric touch sheet metal 31 is fixed on the side wall of the lead screw slider 30 with 2 photoelectric touch sheet metal screws 32 to play a role in controlling the photoelectric touch. When the control sheet metal 31 moves on the lead screw, its position is limited. The syringe presses the sheet metal 33 through the syringe and presses the side mounting hole 118-1 of the sheet metal. Use a screwdriver to pass the syringe and press t...

Abstract

The invention relates to an automatic injection instrument for radioactive substances. The automatic injection instrument comprises a power and stroke control part and an injection source; the power and stroke control part comprises lead screw fixing frames and lead screws fixed between the lead screw fixing frames; sliding blocks are arranged on the lead screws; injector downward-pressing platesare installed on the sliding blocks; the lead screws are connected with a motor; the injection source comprises an injector and a liquid three-way valve; the output end of the injector is connected with the liquid three-way valve; the liquid three-way valve is connected with a flow guide pipe; the motor is used for driving the lead screws to rotate; the lead screws are used for driving the slidingblocks to move vertically; and the sliding blocks are used for driving the injector lower pressing plate to move downwards to push the injector to inject liquid. The motor and the injector are adopted to achieve liquid injection; and injection with a person far away from the mold body is achieved in a guide rail mode and a wireless communication mode, automatic injection is achieved, radiation tothe person in the injection process is avoided, and the injection efficiency is improved.

Description

technical field [0001] The invention relates to the field of radiation protection, in particular to an automatic injector for radioactive substances. Background technique [0002] In accordance with the national standard "Radionuclide Imaging Equipment Performance and Test Rules Part 1 Positron Emission Tomography Device" GB / T 18988.1-2013 and NEMA NU-2 standards, in the quality control and performance testing of PET / CT equipment, it is necessary to In situ testing of count rate characteristics and scatter fraction metrics. Due to these 2 indicators the radiopharmaceutical required in the test 18 The activity of F is relatively large, and the activity range of radiopharmaceuticals recommended by most PET / CT equipment manufacturers is between 740MBq and 1110MBq. 18 The energy of gamma rays after the annihilation of positrons and electrons emitted by F is 0.511MeV, the radiation dose to equipment quality control and testing personnel is relatively large, and the maximum dose...
