Description

Technical Field

[0001] The utility model relates to the technical field of anorectal medication dispensers, in particular to a multifunctional medication dispenser. Background Art

[0002] Anorectal diseases are common clinical diseases with symptoms such as constipation, diarrhea, bleeding, swelling and pain. The prevalence rate in the population is high. Currently, rectal administration is the most widely used treatment method in the treatment of anorectal diseases. The principle of rectal administration to treat anorectal diseases is to administer different types of drugs into the rectum. The drugs take effect locally in the rectum and can be absorbed through the rectum to achieve the treatment purpose.

[0003] Since the anorectal drug delivery device requires the drug delivery head to be inserted into the patient's anus and rectum for drug delivery, and the existing drug delivery device directly loads the drug into the drug delivery device for drug delivery, when applying medicine to the patient's anus and rectum, several kinds of medicine are usually applied or the drug delivery device is loaded with too little medicine, and the drug delivery device needs to be pulled out of the patient's anus and rectum and reinserted. This repeated insertion will cause great discomfort to the patient and reduce the drug delivery efficiency.

[0004] Therefore, the utility model provides a multifunctional drug dispensing device to solve the problems raised in the above background technology. Utility Model Content
