Capsule type alimentary tract fluid taking device controlled by external magnetic field and capsule body of capsule type alimentary tract fluid taking device

Abstract

The invention provides a capsule type alimentary tract fluid taking device controlled by an external magnetic field, and a capsule body in the capsule type alimentary tract fluid taking device. Underthe assembling condition, due to restraint of limiting structure jointly consisting of a rotating limiting pin on an inner housing of a capsule and a rotating limiting groove in an outer housing of the capsule, as well as an inclined angle formed between a magnetic pole of a first magnetic cylinder fixed in the inner housing of the capsule and a magnetic pole of a second magnetic cylinder fixed inthe outer housing of the capsule, rotation torsion is generated, so that the capsule is always under an internal closed combined condition; when an external magnetic field is exerted, one or more orboth of the first magnetic cylinder and the second magnetic cylinder rotate under the effect of the external magnetic field; the rotation between the magnetic cylinders drives the mutual rotation of the inner housing and the outer housing of the capsule, malposition of fluid inlets in the inner housing and the outer housing is eliminated, and the fluid inlets are under an opening condition when the external magnetic field is exerted; and when the external magnetic field is withdrawn, the fluid inlets in the inner housing and the outer housing are under a malposition enclosing condition, so that the purpose of fluid taking is realized. Through the adoption of the capsule type alimentary tract fluid taking device disclosed by the invention, the operation of fluid taking is convenient, and the capsule volume is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a capsule-type digestive tract liquid-taking device controlled by an external magnetic field and a capsule body thereof. Background technique [0002] Due to the accelerated pace of work and uneven diet of modern people, the incidence of digestive tract diseases is increasing day by day. Gastrointestinal diseases have become common diseases that affect the health of modern people, and are developing towards younger age and concealment. The detection of digestive tract diseases plays an important role, and the total length of the human digestive tract is more than 9 meters. Since the digestive tract is a slender pipe, it is distributed between various organs of the human body, and the irregular closure of the entire digestive tract structure poses a threat to clinical practice. Detection and sampling of upper gastrointestinal disorders pose significant challenges. [0003...

AI Technical Summary

Problems solved by technology

Since the above driving mechanism is integrated in the capsule body, in view of the miniaturization of the capsule itself, loading a driving mechanism will inevitably cause problems such as complex structure, low reliability and small capacity of the capsule.
