Description

Technical Field

[0001] The invention relates to the technical field of tumor nursing, and in particular to a medicine dispensing device for tumor nursing. Background Art

[0002] In cancer care, medication dispensing is a very important part. Many cancer patients experience symptoms such as pain, nausea, and vomiting. The rational use of symptomatic supportive drugs such as analgesics and antiemetics can effectively relieve these discomforts and improve the patient's quality of life. Certain drugs may undergo chemical reactions after mixing, resulting in precipitation, decomposition or neutralization, which will affect the efficacy and safety of the drugs. Therefore, in cancer care, it is very important to ensure that the drugs are fully mixed. However, in the process of dispensing, some drugs require several liquid medicines to be extracted from the medicine bottle through a syringe and then manually shaken to mix.
