In this way, the inner tube can be smoothly inserted into the patient's rectum, improving the patient's treatment comfort.

Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to a rectal medication device for digestive endoscopic treatment. Background Art

[0002] Rectal administration refers to the delivery of drugs into the intestine through the anus, and the drugs are directly absorbed into the general circulation by the middle rectal vein, the lower rectal vein and the anal vein. Since the drugs do not pass through the liver, the first-pass detoxification effect of the liver is avoided, and the blood drug concentration is increased. It is a drug administration method that is rapidly absorbed by the rectal mucosa into the general circulation to exert the drug effect to treat systemic or local diseases. There are three main methods of rectal administration: retention enema, rectal drip, and suppository insertion. The existing suppository insertion method generally requires medical staff to manually deliver the suppository into the patient's rectum. However, since it is difficult to control the force of manual drug delivery, the patient's treatment comfort is low, and it is difficult for medical staff to accurately deliver the suppository to the affected area of ​​the patient's rectum, resulting in poor drug administration effect. Summary of the invention

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a rectal drug delivery device for digestive endoscopic treatment, which can smoothly extend an inner tube into the patient's rectum to improve the patient's treatment comfort, and can more accurately deliver suppositories to the affected part of the patient's rectum to improve the accuracy of drug delivery.

[0010] In one embodiment, the inner diameter of the inner tube is the same as the diameter of the suppository.

[0011] Beneficial effects: 1. The medical staff rotates the pushing screw so that the pushing screw extends into the outer tube. During the process of the pushing screw extending into the outer tube, the inner tube is pushed to be smoothly extended into the patient's rectum. The medical staff stops rotating the pushing screw, and then pushes the pushing rod so that the pushing rod moves away from the pushing screw. The reset spring is compressed, and the pushing rod is restricted by the inner tube after moving a certain distance along the inner tube. The movement of the pushing rod pushes the suppository in the inner tube out of the inner tube, and then the suppository is injected into the designated position of the patient's rectum. In this way, the inner tube can be smoothly extended into the patient's rectum, thereby improving the patient's treatment comfort.
