Adjustable type optical-fiber visual hard laryngoscope for guiding intubation via nose

Abstract

The invention discloses an adjustable type optical-fiber visual hard laryngoscope for guiding intubation via the nose. The adjustable type optical-fiber visual hard laryngoscope comprises a handle and a laryngoscope body. The laryngoscope body includes a hard laryngoscope body and a soft laryngoscope body which are connected. The handle is vertically connected with the hard laryngoscope body. The hard laryngoscope body comprises a linear section and a semicircular section, and the diameter of the semicircular section is 9-12cm. The adjustable type optical-fiber visual hard laryngoscope has the advantages that the laryngoscope is visual through an optical fiber, an objective lens and an eyepiece, the plasticity of the laryngoscope is achieved through the hard laryngoscope body, the laryngoscope is adjustable through the soft laryngoscope body, and accordingly the laryngoscope is convenient in clinical operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an adjustable optical fiber visible hard transnasal intubation-guiding laryngoscope. Background technique [0002] Tracheal intubation to establish an artificial airway is an important measure to rescue respiratory failure and save lives. There are mainly two kinds of oral and nasal intubation, among which oral intubation is the most common, but nasal intubation must be used in many cases. There are many guiding tools for oral intubation, such as light stick, fiberoptic bronchoscope, intubating laryngeal mask, video laryngoscope, TruviewEVO2 laryngoscope, etc. The degree of visualization is getting higher and higher, which solves a considerable part of what may have been considered as difficult gas in the past. Tao question. [0003] Many patients have respiratory failure at the same time, due to certain factors, the maxillofacial muscles are stiff and the jaws are ...

AI Technical Summary

Problems solved by technology

Advantages: Convenience, intubation can be completed without equipment skills; Disadvantages: It is closely related to the operator's experience, time-consuming, low success rate, easy to cause soft tissue damage

Advantages: Compared with blind intubation without guidance, it can increase the success rate of one time and shorten the intubation time, and reduce the nasal soft tissue injury and bleeding caused by the poor curvature of the catheter when passing through the posterior nasal cavity; Disadvantages: Cannot be seen clearly, and the angle cannot be adjusted

Disadvantages: Can't look directly, there is no clear basis for setting the curvature, it needs an experienced anesthesiologist to complete it, and the first-time success rate is not high

[0008] 4. Fiber bronchoscope: Advantages: it can be seen clearly, can be bent, can attract and administer drugs, and is the most effective guiding tool so far; disadvantages: it is soft and cannot be fixed in shape, it is difficult to adjust the angle, and it is not easy to quickly complete the insertion in a short time tube (the average intubation time is about 3 minutes), the operation is complex, proficiency requires long-term training, and the price is expensive, and many primary hospitals are not equipped
