Intestinal drug delivery device for gastroenterology

Abstract

The invention belongs to the technical field of medical aids, and discloses an intestinal drug delivery device for gastroenterology, including an outer tube, a spherical guide integrally formed at the front end of the outer tube, and an inner tube assembly penetrating through the rear end of the outer tube; wherein: The middle part of the spherical guide head is provided with a through hole; two connecting rods are symmetrically fixed on the outer wall of the inner tube assembly, and an ellipsoidal drug outlet head is rotated between the two connecting rods, and the drug outlet head Either end of the long axis can pass through the through hole, and the maximum aperture of the through hole is smaller than the short axis of the drug outlet head; one end of the drug outlet head is provided with a drug outlet hole, and the inner tube assembly is used for the drug outlet hole When passing through the through hole, the drug liquid is sent into the drug outlet head; in summary, in the present invention, based on the setting of the rotatable drug outlet head, when the integral drug delivery device is inserted into the patient's intestinal tract, its output The drug hole faces the inside of the outer tube, thereby effectively avoiding the problem of blockage of the drug outlet hole during the insertion of the drug delivery device.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary devices, and in particular relates to an intestinal drug delivery device for gastroenterology. Background technique [0002] Gastroenterology is a third-level clinical discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Gastroenterology has a wide variety of diseases, a wide range of medical knowledge, and complex and delicate operations.

Problems solved by technology

[0003] The above-mentioned drug delivery devices are all provided with a drug delivery port at the front end of the device itself, and when the drug delivery device is inserted into the patient's intestinal tract, the front end of the device is also inserted first, which is very easy to cause the drug delivery port at the front end. Blockage, after the blockage, the drug administration cannot be performed, and the drug delivery device needs to be replaced and re-inserted, which affects the treatment efficiency and the overall comfort during the treatment process is poor
