pet-ct radiopharmaceutical automatic infusion device

Abstract

The invention discloses a PET-CT radiopharmaceutical automatic infusion device, which includes a radiation protection module, a liquid storage module, an infusion module and a control module; the radiation protection module includes an integral radiation protection body, a radiation protection chamber and a radiation protection tank; the storage The liquid module includes glass bottles for storing radiopharmaceuticals, liquid distribution bags, waste liquid bottles and saline bottles; the infusion module includes pipelines, peristaltic pumps, and stop valves; the control module includes radiation dose sensors, operation panels, central control chips and peripherals. circuit. The invention can measure the radiation amount of radiopharmaceuticals in real time, automatically configure and infuse injections with required radiation doses, and effectively protect medical workers at the same time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a PET-CT radiopharmaceutical automatic infusion device. Background technique [0002] The full name of PET-CT is Positron Emission Tomography / X-ray Computed Tomography, which can provide anatomical imaging and functional imaging. PET-CT is the functional fusion of PET scanner and advanced spiral CT, which is widely used in the early detection and diagnosis of major diseases in the fields of tumor, brain and heart. [0003] The unique role of PET is based on metabolic imaging and quantitative analysis, using short-lived nuclides that make up the main elements of the human body, such as 11 C. 13 N. 15 O. 18 Positron nuclides such as F are used as tracers, which can quickly obtain multi-level tomographic images, three-dimensional quantitative results and three-dimensional whole body scans, and can also dynamically observe the physiological and biochemical changes of metabolites ...

AI Technical Summary

Problems solved by technology

The gamma-ray photon energy emitted by PET-CT radiopharmaceuticals is 511kev, and protective equipment such as lead protective clothing and lead glasses have poor protection against PET-CT radiopharmaceuticals.

It takes about 5 minutes for medical staff to inject each patient. Although the protective injection table and shielded syringe are used for operation, due to the unreasonable design, the two ends of the syringe protective cover are open, which can only protect a small amount of dose from the front, and cannot effectively protect medical workers.

Radiopharmaceuticals are always in the process of decay, and medical workers need to re-measure the radiation dose before calculating the required dose every time they inject. This process also greatly increases the chances of medical workers being irradiated, and manually controlling the syringe to extract radioactive drugs will not Very accurate, it will lead to the inaccuracy of the total amount of radiation injected by the patient, which will affect the effect of imaging
