[0003] The traditional drug delivery method discharges drugs through the way of opening holes on the outer wall, which is difficult to ensure that the drugs can be accurately delivered to the designated position in the intestine. Moreover, the diseased area is on one side, and when discharging drugs, the outer wall of the drug delivery device discharges drugs comprehensively, resulting in the release of some drugs in the non-target area, affecting the therapeutic effect and the drug absorption rate, and affecting the bioavailability of drugs. Therefore, it is not convenient to accurately and quantitatively deliver the drug dosage to the diseased area in the patient's intestine. In addition, the existing drug delivery device needs to be connected to an infusion tube for drug delivery. When the infusion device stops drug delivery, the drugs remaining in the drug delivery device will still be discharged outward, resulting in excessive drug delivery and burden on the patient's intestine.

After the drug injection cavity is filled with the drug, the drug delivery holes 12 can be made to communicate with the inner and outer drug delivery holes 12 by pushing the outer drug delivery tube 1, and the drug is delivered to the intestine. At this time, the infusion device continuously infuses inward, and the subsequent infusion volume is the amount of drug discharged from the infusion cavity into the intestine. After reaching the infusion dose, the drug delivery holes 12 are directly closed by pulling the inner drug delivery tube 11, so that the liquid medicine in the cavity is in the cavity blocked by the partition plate 21, thus realizing the precise control of the injection of the liquid medicine, making the device conducive to accurately administering medicine to the diseased part of the patient's intestine, facilitating the recovery of the diseased part of the patient's intestine. The mounting plate 3 fixedly connected to the outer end of the outer drug delivery tube 1 is used to mount the rotating ring 31, enabling the rotating ring 31 to rotate, so that one end of the positioning frame 32 can be connected to the central tube 241, so that medical staff can rotate the inclined tube 24 by rotating the rotating ring 31, thereby adjusting the docking position of the central tube 241 with different medicine inlet holes 22.,

[0020] One end of the outer drug delivery tube 1 is fixedly connected with an arc head 13, and the outer wall of the inner drug delivery tube 11 is fitted with the inner wall of the outer drug delivery tube 1; the arc head 13 fixedly connected to one end of the outer drug delivery tube 1 is used to facilitate medical staff to pass the outer drug delivery tube 1 through the anus and into the rectum, reducing the friction on the patient's intestine. The outer wall of the inner drug delivery tube 11 is fitted with the inner wall of the outer drug delivery tube 1 to ensure that after the drug delivery holes 12 opened on the inner drug delivery tube 11 and the outer drug delivery tube 1 are misaligned, the drug does not flow out.,

[0021] A limiting groove 111 is opened on the inner wall of the inner drug delivery tube 11, and a limiting ring 231 fixedly connected to the outer wall of the rotating plate 23 is matched with the limiting groove 111; the limiting groove 111 opened on the inner wall of the inner drug delivery tube 11 is used to limit the limiting ring 231 fixedly connected to the outer wall of the rotating plate 23, enabling the limiting ring 231 to rotate on the inner wall of the inner drug delivery tube 11 while adjusting the position of the inclined tube 24, ensuring that it is closely attached to the fixing plate 2, and enabling the inclined tube 24 to inject the liquid medicine into the cavity blocked by the partition plate 21.,
