Description

technical field [0001] The invention relates to a drug delivery device. Background technique [0002] At present, when some patients are undergoing disease treatment, they usually need to be directly administered to the lesion to achieve the best effect. For example, in the clinical treatment of anorectal diseases such as hemorrhoids, anal administration is usually performed, and the drug is sent into the anus through the anus during administration. The rectum, through the rectal mucosa, quickly absorbs and enters the large circulation. However, the previous drug delivery device has a single function. When the medical staff administer the drug, it will cause uneven and uneven drug delivery. At the same time, if the drug delivery speed cannot be controlled, it will also cause Leakage and waste, due to the difficulty in the administration and treatment of anorectal diseases, the administration device needs to be convenient to operate and flexible to control. For this reason, ...
