Embodiment 1

[0014] Example 1. Patient 1, female, 64 years old, rectal cancer, for PET / CT (positron emission computed tomography) examination, need to inject positron tracer 18 F-FDG ( 18 F-2-fluoro-2-deoxy-D-glucose), using the method described above, using a three-way connector Unicom syringe for injection. First, use an indwelling needle to establish intravenous access at the injection site on the patient's hand, and the indwelling needle is connected to one end of the three-way connector. The other end of the three-way connector is connected with a physiological saline infusion set. Remove the radiopharmaceutical syringe from the lead bucket, dosed with 6.9 mCi (millici) of radiopharmaceutical before injection, and connect to the third end of the three-way connector. Rotate the switch regulating valve of the three-way connector, close the output end of the physiological saline infusion set, open the indwelling needle end and the injection end of the radiopharmaceutical syringe, and...

Embodiment 2

[0016] Example 2. Patient 2, female, 70 years old, underwent PET / CT (positron emission computed tomography) examination after ovarian cancer surgery, and needed injection of positron tracer 18 F-FDG ( 18 F-2-fluoro-2-deoxy-D-glucose), using the method described above, using a three-way connector Unicom syringe for injection. Firstly, an indwelling needle is used to establish venous access at the injection site on the patient's hand. The indwelling needle is connected to one end of the three-way connector, and the other end of the three-way connector is connected to the output end of the saline infusion set. Remove the radiopharmaceutical syringe from the lead barrel, the dose of radiopharmaceutical is 5.58 mCi (millici) before injection, and connect the syringe to the third end of the three-way connector. Rotate the three-way connector to switch the regulating valve, close the saline end, open the indwelling needle end and the syringe end, and inject radiopharmaceuticals in...

Embodiment 3

[0018] Example 3. Patient 3, male, 70 years old, lung space-occupying, PET / CT (Positron Emission Computed Tomography) examination for the second time, requiring injection of positron tracer 18 F-FLT (3'-deoxy-3'- 18 F-fluorothymidine), which contains 10% ethanol), was injected using the three-way connector as described above. Firstly, an indwelling needle is used to establish venous access at the injection site on the patient's hand. The indwelling needle is connected to one end of the three-way connector, and the other end of the three-way connector is connected to the output end of the saline infusion set. Remove the radiopharmaceutical syringe from the lead barrel, with a dose of 7.82 mCi (millici) of radiopharmaceutical before injection, and connect to the third end of the three-way connector. Rotate the three-way connector to switch the regulating valve, close the output end of the physiological saline infusion set, connect the end of the indwelling needle and the end ...

Abstract

The invention discloses an intravenous injection method of a radiopharmaceutical. The intravenous injection method comprises the following steps: a venous channel is established by utilizing a remaining needle and is connected with one end of a three-way connector, and a normal saline infusion apparatus is connected with the other end of the three-way connector; an injector provided with the radiopharmaceutical is taken from a protection device, the air is discharged manually, and the injector is connected with a third end of the three-way connector; a switch control valve of the three-way connector is rotated, the normal saline output end is closed, the remaining needle end and the injector end are communicated, and the radiopharmaceutical is injected to the vein; the switch control valve of the three-way connector is rotated, the remaining needle end is closed, the normal saline end and the radiopharmaceutical injector end are communicated, and the normal saline is injected into the injector; and then the switch control valve of the three-way connector is rotated, the normal saline output end is closed, the injector end and the remaining needle end are communicated, residues in the remaining needle are flushed and are pushed into a patient body. By adopting the method provided by the invention, the dose injected into a patient is more accurate, and meanwhile, safety of medical personnel and patients can be protected.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to an intravenous injection method of radiopharmaceuticals. Background technique [0002] Radiopharmaceuticals typically use emitting beta - Radionuclide labeling of ions and gamma photons, especially positron radiopharmaceuticals, the positrons will emit two gamma photons with energy of 511KeV (kiloelectron volts) in opposite directions during the decay process, which has higher radiation energy. If there are no good protective measures, it will cause greater radiation damage to patients and medical staff. The general principle of radiation protection is to reduce the contact time of radioactive sources, increase distance and radiation shielding. [0003] The current intravenous injection of radiopharmaceuticals generally adopts the following methods: use a 5 mL syringe to extract normal saline, select a suitable indwelling needle to establish an intravenous channel; take out the syringe ...
