specific Embodiment approach

[0032] Specific implementation: before using the extractor press Image 6 Assemble. The digestible first arc clip 005 is installed in the first opening 007 of each group of openings, and the second arc clip 006 is installed in the third opening 009 of each group of openings. At this time, the internal spring is in a compressed state, and the first arc-shaped locking member 005 fixes the capsule-shaped inner shell 001 so that it will not be ejected from the outer shell by the spring. The enteric-coated capsule skin 004 is put on the frame of the small intestinal juice extractor to close the second opening 008, which can prevent gastric juice from entering the capsule. When in use, the patient swallows the small intestinal fluid extractor, and because of the wrapping of the enteric capsule skin 004, the second opening 008 is in a closed state before the small intestinal fluid extractor reaches the small intestine. When the small intestinal juice reaches the small intestine, th...

Abstract

The embodiment of the invention provides a small intestinal juice extracting device. The device comprises a capsule-shaped inner housing, a capsule-shaped outer housing, a compression spring-sponge compound body, an arc-shaped clamping member and enteric coated capsule skin; the compression spring-sponge compound body is assembled in the capsule-shaped inner housing; the capsule-shaped inner housing, the capsule-shaped outer housing and the arc-shaped clamping member are assembled to form a complete capsule skeleton; the enteric coated capsule skin wraps the complete capsule skeleton. The small intestinal juice extracting device has the advantages of simple structure, convenient assembly, low cost and convenient batch production; the sealing performance of the capsule is better, and a small intestinal juice specimen is prevented from being contaminated by large intestine juice and gastric juice; the inner housing, the outer housing and the spring are made from degradable materials andcan be slowly degraded, and therefore the safety performance of the small intestinal juice extracting device is improved.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, in particular to a small intestinal fluid extractor. Background technique [0002] The human digestive tract is divided into esophagus, stomach, duodenum, jejunum, ileum, colon, and rectum. The digestive juice in the digestive tract is an important specimen for the diagnosis of digestive tract diseases. At present, the digestive juice of the stomach, esophagus, and duodenum above the Tresch ligament can be obtained by gastroscopy, and the digestive juice of the colorectum can be obtained by colonoscopy. However, because enteroscopy requires high equipment and operating techniques, and enteroscopy itself is time-consuming and labor-intensive, there is still no simple and convenient method for obtaining digestive juices from the duodenum, jejunum, and ileum below the Trout's ligament. [0003] Various capsule endoscopy methods are used to obtain imaging data of the small intes...
