Description

Suppository Drug Precise Dose Intraanal Applicator

technical field

The utility model relates to the technical field of medical devices, in particular to an intraanal drug delivery device for precise dosage of suppositories.

Background technique

Anal administration, that is, rectal administration, generally requires the drug to be inserted about 5cm above the anus. At present, a variety of drugs in clinical use can significantly stimulate the gastrointestinal mucosa after oral administration, and may cause gastrointestinal bleeding. In addition, comatose patients or patients with other conditions cannot complete the oral administration of drugs, so the anus is a more practical and ideal Method of administration. Traditionally, the anus is generally manually operated, and the drug is administered directly through the anus by the fingers. The patient is more painful during the administration process, which is likely to cause contact infection and bring psychological burden to the patient. At the same time, for the elderly, children and patients with poor health, the dosage is usually reduced, and the suppository for administration needs to be cut manually, which makes it difficult to accurately dose the medicine, which is easy to cause pollution of the medicine, and also causes waste of the remaining medicine.
