Problems solved by technology

[0004] Furthermore, nuclear medicine examinations have very strict requirements on the patient's drug injection dose and injection time, and inaccurate injection dose or injection time will have a great impact on the imaging quality of the examination
[0005] As far as the applicant knows, when the nuclear medicine department involves drug repacking, the patient's injection dose is often based on the dose reported by the repacking personnel. The dose reported by the repacking personnel cannot accurately determine the dose of the syringe, so the dose of the injected drug is not accurate enough.
At the same time, in actual operation, the injection personnel did not complete the injection process in time after the subpackaging personnel subpackaged the drug, which greatly increased the attenuation of the radioactive drug and greatly reduced the dose of the injected drug

Embodiment 1

[0034] The radiopharmaceutical automatic dispensing and injecting apparatus of the present embodiment, as figure 1 As shown, it includes a drug dispensing and injection unit 1 and a controller 2 provided with an external data input port 2-1.

[0035] The operator can input instructions to the controller 2 through the external data input port 2-1 of the controller 2, and select the radiopharmaceutical stock solution tank 3 to be dispensed. The instructions contain data on the patient's weight and the type of radiopharmaceutical to be selected, among others.

[0036] There can be one or more medicine dispensing and injection units 1 .

[0037] One controller 2 can be configured for each medicine dispensing and injection unit 1 , or can be configured for multiple medicine dispensing and injection units 1 .

[0038] The drug subpackaging and injection unit 1 includes a solvent tank 4, a radiopharmaceutical stock solution tank 3 placed in an isolation cover 5, and an injection pr...

Embodiment 2

[0064] The radiopharmaceutical automatic dispensing and injection apparatus of the present embodiment is an improvement on the basis of Embodiment 1, as figure 2 As shown, the improvements are:

[0065] The switch valve is a selection valve 8, which contains a first opening a and eight second openings b, c, d, e, f, g, h, k that can be connected to the first opening respectively. The selection valve 8 For the specific structure, please refer to pages 5-6 of the specification of the Chinese patent "Automatic Chemical Analyzer" of Patent No. CN200720043444.9.

[0066] The inlet and the outlet of the syringe 6-1 are an outlet, both communicate with the first opening a, one of the second opening f communicates with the solvent tank 4, and the second opening e communicates with the radiopharmaceutical stock solution tank 3, and the second opening f communicates with the radiopharmaceutical stock solution tank 3, and Two openings terg are connected to the external injection port 6...

Abstract

The invention relates to an automatic radioactive medicament split charging injector and an automatic radioactive medicament split charging method, belonging to the technical field of containers dedicated to medicine purpose. The automatic radioactive medicament split charging injector comprises a medicament split charging injection unit and a controller provided with an external data input port. The method is as follows: the external data input port of the controller is utilized for inputting an instruction to the controller, and a radioactive medicament basic solution tank needing to be subjected to split charging is selected; the active value of the medicament in the radioactive medicament basic solution tank can be measured by a radioactive activity instrument, the controller calculates the volume of the needed radioactive medicament according to the active value measured in real time and the instruction, and the automatic split charging of the radioactive medicament can be completed by controlling the opening and closing of a switch valve between the injector and the radioactive medicament basic solution as well as between the switch valve and a solvent tank. According to the automatic radioactive medicament split charging injector and the automatic radioactive medicament split charging method, the automatic split charging and injection can be conducted on the radioactive medicament, and the condition that an injection person is not hurt by radiation can be ensured.

Description

technical field [0001] The invention relates to a device and a packing method for radiopharmaceuticals, and belongs to the technical field of containers specially used for medical purposes. Background technique [0002] Under current conditions, the injection of radiopharmaceuticals in the Department of Nuclear Medicine requires the injector to hold a syringe containing a very strong radiopharmaceutical to inject each patient. In some hospitals, dozens or even hundreds of patients need to be injected every day, and the intensity of medical exposure suffered by the injectors is very high, which poses a great potential health threat to the injectors. [0003] Furthermore, personnel need full protection during the subpackaging and injection process, but the radiation of radiopharmaceuticals is hard to guard against, and the subpackaging and injection process is likely to cause pollution to the protective facilities. This virtually increases the cost of radiation protection. ...
