Anti-radiation dosing, split-charging and injection device and method

Abstract

The invention discloses an anti-radiation dosing, split-charging and injection device and method. The device comprises a dosing and injection unit, an external port and an anti-radiation isolation tank, wherein the dosing and injection unit is arranged in the anti-radiation isolation tank and comprises a source liquid bottle, a normal saline bottle, a waste liquid bottle, a measurement bottle, an activity measuring instrument, a dosing device, a dosing device linkage unit and a controller, and the activity measuring instrument is used for measuring activity of a medicine liquid in the measurement bottle in real time; an inlet of the dosing device is connected with the source liquid bottle, the measurement bottle and the normal saline bottle through pipelines provided with valves respectively, and an outlet of the dosing device is connected with the waste liquid bottle and the external split-charging and injection port through pipelines provided with valves respectively. According to the device and the method, the problems of transfer, split-charging and injection of the radioactive source liquid are integrally solved, split-charging and injection can be performed manually or automatically, all parts contacted with a drug can be replaced, so that external pollution and external radiation to the drug are avoided, and meanwhile, the pollution of the drug to the machines is also avoided.

Description

technical field [0001] The invention relates to the field of radiation protection liquid preparation, packaging and injection, in particular to a radiation protection liquid preparation, packaging and injection device and method. Background technique [0002] Under the current conditions, the dispensing and injection of radiopharmaceuticals in nuclear medicine requires the operator to hold a dispenser containing strong radiopharmaceuticals for dispensing or injection. In some hospitals, dozens or even hundreds of patients need to be injected every day. The personnel lack full protection during the packaging and injection process. The medical exposure intensity of the injectors is very high, which brings great potential health risks to the injectors. threaten. At the same time, safe and reliable devices are required in the process of subpackaging and injection to ensure that the process of subpackaging and injection does not cause pollution to protective facilities.

AI Technical Summary

Problems solved by technology

When nuclear medicine involves drug packaging, the patient's injection dose is often based on the dose reported by the packaging personnel. The dosage reported by the packaging personnel cannot accurately determine the dose of the dispenser, so the dose of the injected drug is not accurate enough

[0004] At the same time, in actual operation, dispensing and injection are two separate links, which increases the difficulty of radiation and pollution protection, and causes untimely injection, increases the attenuation of radiopharmaceuticals, and greatly reduces the dose of injected drugs
