Description

Protective device for heating radiopharmaceuticals

Technical Field

The invention relates to the technical field of medicine production and processing equipment, in particular to a protection device for heating radiopharmaceuticals.

Background

Radiopharmaceutical refers to a radionuclide preparation or a labeled compound thereof for clinical diagnosis or treatment. Radiopharmaceuticals differ from other pharmaceuticals in that the radionuclide they contain emits radiation, and so drugs containing radionuclides either within the molecule or in formulations are referred to as radiopharmaceuticals.

As shown in fig. 3, in the prior art, the radiopharmaceutical needs to be heated during production, and the heating mode generally adopts water bath heating, which specifically includes: an electromagnetic oven is placed on the workbench, an electric heating pot is placed on the electromagnetic oven, water is filled in the electric heating pot, the radioactive medicines to be heated can be directly placed in the electric heating pot, the water in the electric heating pot is boiled through the electromagnetic oven to achieve the purpose of heating the radioactive medicines, and the position where the operation is carried out on one side of the workbench is called as an operation surface of the workbench. Here in order to block the ray of radiopharmaceutical, in the both sides of workstation and the one side that deviates from the operation face respectively with the plumbous partition wall of the vertical rigid coupling one side rectangle in ground, trilateral partition wall is the U type and distributes, be close to the subaerial vertical baffle that has a plumbous system of workstation operation face one side, the baffle all has the certain distance with the partition wall of workstation both sides, the staff can follow the work such as radioactive drug and operation electromagnetism stove of putting of one side of baffle. In order to observe the heating condition of the radiopharmaceutical, the position of the baffle close to the top end is provided with an opening, the opening is fixedly connected with a glass window, and meanwhile, the position of the baffle can be inclined upwards towards the workbench, so that the worker can observe the heating condition of the radiopharmaceutical in the electric food warmer conveniently.

The distances between the induction cooker and the electric food warmer and between the partition wall and the baffle are accurately measured, so that the radioactive rays at the radioactive medicine emitting position in the electric food warmer can not be emitted from the space between the partition wall and the baffle.

The above prior art solutions have the following drawbacks: the device for heating the radiopharmaceutical can ensure that the degree of freedom of a working space is higher, namely the operable range of workers is wider, and meanwhile, although the distances between the induction cooker and the electric food warmer and between the partition wall and the baffle are accurately measured, the radioactive rays cannot be prevented from being touched due to manual operation errors in the working process, so that the harm is caused to the workers.
