Description

Radiation protection injection device

Technical field

The invention belongs to the technical field of radiation protection medical devices, and in particular relates to a radiation protection injection device.

Background technique

For the injection of nuclear medicine imaging drugs, in order to protect the workers from radioactivity, bedside injections are required after a dedicated window with a protective screen or a protective screen. At the time of drug injection, the current commonly used measures are lead gloves, but it will affect the sensitivity of the operation and increase the difficulty of operation; or use the radiation-proof injection lead sleeve to reduce the radiation, but the operation is not easy, and each injection requires The staff went to the fume hood to take the injected syringe out, put it in the radioactive waste, then replace the syringe filled with the drug, and then inject the next patient, which would take part of the time and affect the work efficiency. Therefore, in the real workplace, some staff members will use the ordinary medical gloves for injection operation only in the case of protective screen isolation for the convenience of operation, accurate injection and time saving, so that it is inevitable for the operator's hand. To radiation hazards.

The radioactive drugs and physiological saline used in imaging are colorless, especially in the dynamic imaging of diuretic kidney. In addition to the application of physiological saline and radioactive drugs, furosemide is required. These drugs are colorless; in imaging, Their injections are in a certain order, so in order to ensure the correct injection sequence, it is necessary to mark the needle on the needle tube, which increases the work complexity. Even then, before the bolus, it is necessary to confirm that the needle is correct. To avoid errors.

Injecting the drug operation step: the first step is to use a syringe filled with physiological saline, a hose needle is connected to the front to establish a venous access; the second step is to bend the side of the needle connected to the syringe and replace the syringe with the radiopharmaceutical. For the bolus, the third step is to bend the side of the hose needle connected to the syringe again, replace it with furosemide, and make a bolus. In this process, the staff needs to be skilled, but it is also inevitable during the bending process. Pulling the established venous channel out of the blood vessel causes the injection to fail; and during the process of replacing the syringe, it is inevitable that a drug or the like will flow out from the other side of the thin needle that is opened and ready to be replaced, which may result in radioactive drug contamination check. Bed, operator's hand, patient's clothing, etc.; and dynamic imaging of the kidney, in order to ensure the quality of the image, a "ball" injection is required, but in the process of replacing the syringe multiple times, the staff is required to move quickly, even if it is inevitable of The injection time is extended and the efficient "shot" injection cannot be guaranteed.

Renal dynamic imaging acquisition position: The patient is placed on the examination bed first, the instrument is placed in the collection window, and then the medicine is injected intravenously, and the image is taken at the same time. Therefore, the process of injecting drugs is carried out by the operator at the bedside, even if the isolation protection facilities are used, but the hand is also in a state of no protection.
