A kind of endotracheal intubation guide

Abstract

The invention relates to a guide device of an endotracheal tube, which comprises a guide rod with an arc-shaped end and a handle connected with a tail end of the guide rod. The guide device is characterized in that the guide rod is a hollow rod; the arc-shaped end of the guide rod is connected with a flexible section with micro-adjustable curvature or bending direction; and a control part which can control the curvature or the bending direction of the flexible section of the arc-shaped end of the guide rod is arranged on the handle. The guide device of the endotracheal tube has the advantagesof simple structure and easy operation, the flexible section arranged at the arc-shaped end of the guide rod can control the flexible section at the distal end of the guide rod to bend according to the direction required by the design under the traction of a traction line, thereby forming the special S-shaped bending, leading the bent end of the guide rod to adapt to an anatomical structure of thethroat of a patient with structure variation or pachymucosa or glottic edema or dead angles formed by anterior commissure of vocal cord and other symptoms, and guiding the smooth intubation of the endotracheal tube. The adoption of the guide device of the endotracheal tube for implementing the endotracheal intubation can not only rapidly complete the endotracheal intubation operation, but also reduce the tissue trauma caused by improper operation during the endotracheal intubation process.

Description

technical field [0001] The invention relates to a medical device, in particular to a tracheal intubation guider. Background technique [0002] Endotracheal intubation is an indispensable and important part of clinical anesthesia. It is of great significance to maintain the patient's airway and ensure the safety of the patient's life. It also plays a very important role in the rescue and treatment of critically ill patients. In clinical work, various reasons are often encountered that cause anatomical abnormalities on the intubation path, resulting in difficulty in intubation. The incidence rate of difficult tracheal intubation cases in general hospitals is 1% to 0.04%, in fact, its incidence rate is much higher in small grassroots hospitals. In order to solve the difficulty of tracheal intubation, an intubation guide is clinically available. The existing intubation guide usually consists of a guide rod with an arc-shaped front end and a handle connected to the tail end of ...

Problems solved by technology

However, although the arc-shaped curved end of this intubation guide can be shifted forward and backward a small amount, its angle cannot be changed.

Therefore, in clinical practice, patients with symptoms such as variations in laryngeal anatomy, mucosal hypertrophy, glottic edema, or anterior vocal cord union (see Figure 4 ), even if the intubation guide with the above structure is used, it is difficult to complete the smooth insertion of the tracheal intubation (see Figure 5 )
