An integrated mouth ring device for gastroscopy to prevent tongue from falling back

Abstract

The invention provides an integrated gastroscopy mouth-ring device capable of preventing tongue retropulsion. The device comprises a mouth ring, an inner cannula and a push-pull fixing assembly. The mouth ring comprise a tubular bite body, a check ring and a lip edge, wherein the edge of the check ring is provided with a through hole, the lip edge is arranged at the inner end edge of the bite body, and the outer end of the bite body is sleeved with the check ring; the inner cannula is sleeved with the bite body, and a short rod extending outwards is arranged at the end, close to the check ring, of the inner cannula; the push-pull fixing assembly is fixed to the outer end of the short rod, a strip-shaped opening corresponding to the position of the through hole is formed in the tube wall of the bite body in the axial direction, and a clamping hole used for fixing the push-pull fixing assembly is formed in the position, corresponding to the strip-shaped opening, on the check ring. The bite body, the check ring and the lip edge are formed integrally, and the push-pull fixing assembly penetrates through the through hole, and comprises at least three connection rods and at least two rotational connecting pieces, wherein the connection rods are connected in a head-to-tail mode through the rotational connecting pieces. The push-pull fixing assembly drives the short rod to slide in the strip-shaped opening and drives the inner cannula to slide in an inner tube of the bite body to a preset position, and then the connection rods are rotated to be clamped into the clamping hole so as to fix the inner cannula.

Description

technical field [0001] The invention relates to a mouth ring device for gastroscopy examination, in particular to an integrated mouth ring device for gastroscopy examination which prevents the tongue from falling backward. Background technique [0002] Gastroscopy is used to find and treat upper gastrointestinal lesions, and is accepted by more and more people because of its small trauma and convenient inspection. However, during the examination process, the entry of the gastroscope into the throat will stimulate nausea and vomiting, so many patients will choose painless gastroscopy. [0003] Painless gastroscopy is more comfortable, but the tongue will block the airway during general anesthesia, which increases the risk of the examination. The conventional gastroscope mouth ring used in clinical practice has a tubular bite body and a through hole on the edge. The retaining ring and the edge of the lip set at the inner edge of the bite body. When in use, the gastroscope tub...
