Technical Field

[0001] This utility model relates to the field of digestive tract auxiliary equipment technology, specifically a drug delivery device for the treatment of digestive tract ulcers. Background Technology

[0002] The digestive tract is a muscular tube that originates in the mouth and ends in the anal canal, including the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anal canal. In the treatment of some patients with digestive tract ulcers, there are situations where some patients are unable to swallow medication independently or where there are lesions inside the digestive tract that make medication administration inconvenient. Therefore, it is necessary to use a drug delivery device to administer medication to the ulcer lesions in the patient's digestive tract.

[0004] The above-mentioned technical solution, with its threaded cap, allows for easy disassembly and reassembly of the medication during dispensing. The spring retracts the push rod after medication is inserted, and the opening of the connecting tube further enhances ease of use by allowing medication to be pushed. However, this solution requires the doctor to push the medication tube forward along the patient's digestive tract until the medication delivery end reaches the lesion site. During this extension, the human digestive tract is extremely fragile, and the pressure exerted by the extension end on the tract wall can cause discomfort or even secondary damage. Furthermore, the pressure applied to the tract wall by the extension end cannot be monitored, making the operation of this medication delivery device for treating digestive ulcers inconvenient and unsafe.

[0005] Therefore, those skilled in the art have provided a drug delivery device for the treatment of gastrointestinal ulcers to solve the problems mentioned in the background art. Utility Model Content
