Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pharmaceutical mixer. Background Art

[0002] Medical quality is the eternal theme of the hospital. Strictly implementing diagnosis and treatment routines and standardizing various operations are the fundamental guarantee of medical quality. The most important link in the quality control of nuclear medicine single-photon radioactive drugs is the preparation of drugs. At present, the source of single-photon radioactive nuclide labeled drugs in hospitals is mainly that departments purchase molybdenum-technetium generators and matching medicine boxes for labeling from enterprises, and label and prepare them according to the configuration instructions. Specifically, the molybdenum-technetium generator is transported to the department, and personnel perform leaching to obtain sodium pertechnetate stock solution, which is then injected into the relevant matching medicine box and shaken to mix with the medicine (dry powder) in the bottle. It can be used after passing the quality control.

[0003] However, currently, shaking and mixing are all done manually during preparation. Pharmaceutical workers hold the lead can containing radioactive drugs and shake it back and forth. First, the workers are in close contact with the radioactive drugs, causing external radiation damage to the human body. Secondly, the shaking force cannot guarantee continuous and effective output, so the shaking speed will be fast and slow, and people's arms will feel sore. It is difficult to ensure that the drugs are mixed evenly, and the quality control of the drugs is also difficult to ensure. Even if the drugs are mixed evenly, over time, this situation will also cause compensatory thickening of the arms or muscle strain of the pharmaceutical workers. In view of this, a pharmaceutical mixer is proposed to solve the above problems. Utility Model Content
