Problems solved by technology

[0005] However, the above-mentioned device is provided with an external handle end, thereby blocking the mouth of the animal, and is not suitable for the operation of endotracheal intubation. Based on the above-mentioned situation, it is urgent to design and invent an effective gag to change the difficulty of endotracheal intubation in experimental pigs. and difficult maintenance of intubation during anesthesia

Embodiment Construction

[0036] Such as figure 1 As shown, the two-section gag for animal tracheal intubation in this embodiment includes: an upper jaw expansion plate 1, a lower jaw expansion plate 2, a movable rivet 3 that hinges the two expansion plates, an adjustment strut 4, and a through hole Nut 5, a rope hole and a tongue clip 6 for passing through the fixing belt of the upper jaw expansion plate and the fixing belt of the lower jaw expansion plate.

[0037] The two long sides of the upper jaw expansion plate 1 are folded toward the lower jaw expansion plate to form an upper side baffle 11 , and the two long sides of the lower jaw expansion plate 1 are folded toward the upper jaw expansion plate to form a lower side baffle 21 .

[0038]The connection relationship of the above components: the upper palate expansion plate 1 and the lower jaw expansion plate 2 are connected by two movable rivets 3 on the left and right sides as hinges, and the movable rivets 3 are connected at the intersection of...

Abstract

The invention discloses a two-piece type mouth opener for a tracheal cannula for animals. The two-piece type mouth opener comprises a first opening plate, a second opening plate, an adjusting nut and an adjusting supporting rod, wherein two long sides are turned towards the same side to form first side baffles, and oppositely arranged hinged parts are installed at the same ends of the two first side baffles; the second opening plate is installed on one side of the first opening plate with the first side baffles, the two sides of one end of the second opening plate are connected with the corresponding hinged parts respectively, and the second opening plate rotates relative to the first opening plate so as to adjust the size of a channel formed between the first opening plate and the second opening plate. The plate surface of any one of the first opening plate and the second opening plate is provided with a through hole, and the adjusting nut is connected with the through hole. The adjusting supporting rod penetrates the through hole and is in screw thread fit with the adjusting nut, and one end of the adjusting supporting rod abuts against and is connected with the opening plate which is not provided with the through hole. The two-piece type mouth opener can replace a manual rope loop ligature traction method used currently, the oral cavity of an experiment pig can be kept in an open state without the matching by multiple people, and the opening angle can be adjusted randomly.

Description

technical field [0001] The invention relates to the technical field of medical instruments for animal experiments, in particular to a two-section gag for tracheal intubation for animals. Background technique [0002] With the gradual advancement of medical scientific research, the selection of experimental animals has expanded from small animals such as mice and rabbits to large animals. At present, various medical operations and basic research experiments based on experimental pigs have been vigorously carried out. General anesthesia with endotracheal intubation is a routine anesthesia method for large animal experiments, and the experimental results are good. However, the experimental pig has its special anatomical characteristics. Because of its narrow and long mouth, it is difficult for an ordinary large laryngoscope to reach the root of the epiglottis to expose the glottis. The tongue is thick and the long glottis is easily covered, making tracheal intubation difficult...
