Abstract

A drug-releasing capsule for visualization of digestive tract sampling, comprising a capsule body in a capsule shell. The capsule body is provided with a body cavity, a sampling cavity, and a drug storage cavity, wherein the sampling cavity is located at the lower part of the capsule body, and the drug-releasing cavity is located at the upper part of the capsule body. , the main cavity is in the middle; the main cavity is a piston cavity structure, and a thermal response insert is arranged in the main cavity, and the lower end of the thermal response insert is connected to the top of the sampling chamber through a compression spring, and a photothermal actuator is connected above the thermal response insert , a battery is connected above the photothermal actuator, and a capsule imaging component is connected above the battery; the sampling chamber is a hemispherical chamber with a sampling port at the bottom and a self-locking ball inside, which is formed at the sampling port Self-locking state; the drug storage cavity adopts a hemispherical chamber structure, with a drug release seal on the top and a drug release needle point inside, and the drug release needle is under the drug release seal and pierced into it for fixation; the invention realizes the visualization of the digestive tract Integrated functions of imaging detection, digestive juice collection and drug release.

Description

technical field [0001] The invention belongs to the technical field of digestive tract capsule endoscopy, in particular to a capsule for visualizing digestive tract sampling and releasing medicine. Background technique [0002] Capsule endoscopy has been widely cited in medical diagnosis, such as the Chinese patent "Sampling Capsule Endoscope Based on Shape Memory Spring" with the publication number CN108784633A. The support plate is separated, the collection device cavity and the sealed sampling cavity are separated by a sealing plug, the capsule housing is provided with a sampling hole, the capsule support plate is provided with a conduit communicating with the sampling hole, the capsule controller and the capsule sensor are arranged on the In the electronic control equipment cavity, the spring positioning plate is fixed on the inner wall of the acquisition device cavity, one end of the shape memory alloy spring is fixedly connected to the spring positioning plate, and the...
