Embodiment 1

[0018] Such as figure 2 , image 3 Shown, the present invention comprises two half-pipes, and described half-pipe comprises flange 1, dental pad part 2, pharynx curved part 3, wherein the section of said half-pipe is provided with groove 61, and the section of another said half-pipe The section of the half-pipe is provided with a protrusion 62, and the sections of the two half pipes form a whole through the cooperation of the groove 61 and the protrusion 62. The half pipe can be made of rubber or plastic, and the purpose of designing the flange 1 is to prevent the present invention from entering the oral cavity too deeply. In addition, the flange 1 can also be used to fix the present invention in a correct position. The tooth pad part 2 is straight and is located between the teeth or the alveolar. Its structure must be quite strong to prevent the patient from clenching his teeth and closing the ventilation lumen 4. The pharyngeal flexure 3 is the main body of the airway. It...

Embodiment 2

[0020] Such as Figure 4 As shown, the difference between the present embodiment and the first embodiment is that the sections of the two half pipes are connected by several dots 63, and the present embodiment adopts injection molding, since several dots 63 are used connected so it is easier to separate.

[0021] All the other are the same as the first embodiment.

Embodiment 3

[0023] Such as Figure 5 , Figure 6 , Figure 7 As shown, the difference between the present embodiment and the first embodiment is that the sections of the two half pipes are connected by several positioning rings 51, and several positioning rings 51 are fixed by connecting pins, and the connecting pins can It is an iron wire, which is inserted into the round hole of the positioning ring 51 to connect the two half pipes.

[0024] All the other are the same as the first embodiment.

[0025] The invention is widely used in the field of tracheal intubation guides.

Abstract

The invention discloses a guide of a tracheal cannula, aiming to provide the guide of the tracheal cannula with simple structure, easy operation and convenient use. The invention solves the problems of unreasonable structure, difficult operation and inconvenient use of the tracheal cannula. The guide of the tracheal cannula provided by the invention comprises a flange (1), a dental pad (2), a throat bent part (3) and a breather lumen (4). The tracheal cannula is composed of two semicanals and the semicanals are connected fixedly with each other. The invention can be widely applied to the fieldof the guide of the tracheal cannula.

Description

technical field [0001] The invention relates to a tracheal intubation guide. Background technique [0002] With the development of anesthesiology and critical care medicine, airway management plays an increasingly important role in clinical work. For this reason, the theoretical basis and practical development of airway management have generally attracted the attention of domestic and foreign medical professionals and even the whole society. , everyone is eagerly looking forward to its perfection, progress and improvement. Airway management is one of the important skills that clinical anesthesiologists, emergency physicians and critical care physicians must master. In many emergency situations, whether clinicians can make a quick and accurate judgment on the patient's respiratory condition and give correct treatment is often directly related to the patient's safety. After induction of anesthesia or in some emergency situations, if mask ventilation is used, it is often diff...
