Anti-radiation nuclide sub-packaging device

Abstract

The invention relates to an anti-radiation nuclide sub-packaging device. The anti-radiation nuclide sub-packaging device comprises a medicine taking window, a micro sample feeder, a lead tank and a tray, wherein the medicine taking window is located on the left side of an operation table, the micro sample feeder, the lead tank and the tray are sequentially placed in the middle of the operation table from left to right, the lead tank is filled with nuclide iodine 131, a plurality of medicine distribution cups are arranged on the tray, and totally-enclosed lead glass is arranged between the operation table and an operator; a horizontal driving device for driving the micro sample feeder to horizontally move in a left-right direction along a position above the middle of the operation table is arranged at the rear part of the operation table, and an up-down driving device for driving the micro sample feeder to absorb liquid medicine in the lead tank is arranged at the lead tank; an up-down driving device for driving which is corresponding to the medicine distribution cups and used for injecting the liquid medicine in the micro sample feeder into the medicine distribution cups one by one; a belt driving device is arranged at the front part of the operation table, a horizontal driving device for moving the medicine distribution cups on the tray to the belt driving device is arranged at the tray, and the belt driving device is used for conveying the medicine distribution cups on the tray to the medicine taking window.

Description

technical field [0001] The invention relates to a nuclear medicine nuclide dispensing device, in particular to a radiation protection nuclide dispensing device. Background technique [0002] The current treatment of hyperthyroidism with the radionuclide iodine 131 adopts individualized treatment, that is, the dosage of iodine 131 is determined according to the patient's condition and the absorption and metabolism of iodine 131. Now determine the amount of iodine 131 and pack it now. The prior art is directly operated by hand, and there is a piece of 40 cm wide lead glass on the edge of the operating table, which blocks the operator to reduce exposure to measurement, and the nuclide liquid is placed in a lead tank. The operator puts his hands into the operation table from both sides of the lead glass, draws a certain amount of nuclide liquid medicine from the diluted nuclide radioactive iodine 131 container with an adjustable continuous micro-sampler, and distributes it into...

AI Technical Summary

Problems solved by technology

Disadvantages of the prior art: 1. The hands and arms are too close to the radioactive source and are directly irradiated; 2. Because the lead glass is only 40 cm wide, the shielding is limited, and the medicine-dispensing cup cannot The radioactive source in the device can directly irradiate the operator's body; 3. Due to the close-range operation of the arm, the nuclide drug solution cannot be sucked out at one time, and each portion can only be sucked out by "absorbing the drug solution → aiming at the dispensing cup and ejecting → The whole process of taking the medicine dispensing cup to the medicine taking window→patient taking it will take a long time for dispensing, and the exposure time will also be long
