Description

Neonate laryngoscope with curvature arrangement function

Technical Field

The invention relates to the field of a newborn laryngoscope, in particular to a newborn laryngoscope with a curvature arrangement function.

Background

In clinical work, the most important part of the newborn is the judgment and treatment of the airway of the newborn, and common first-aid operation comprises the intubation of the newborn, which is the basic work of the obstetric nurse and the doctor. However, since the conditions are limited in various places and a large amount of practical experience needs to be matched, the operation of the intubation tube by many medical staff is not smooth.

As a common operation technique for emergency treatment of neonates, tracheal intubation is required to be rapid and accurate. It is generally necessary to incorporate the look-ahead entry and assistance of the laryngoscope. Since the throat of a newborn baby may have a large amount of filth and the mucous membranes are very fragile. Before delivery, the laryngoscope is in a complete non-starting state, so that the placement of the laryngoscope in the early stage brings great test for doctors. Not only the establishment of the passage is ensured, but also the damage to the throat of the newborn is reduced as much as possible.

There are a great many different laryngoscope brands and styles for clinical applications in neonates, and there are some studies on the design of laryngoscopes for use in clinics, particularly for neonates, and the types of laryngoscopes include video laryngoscopes and ordinary laryngoscopes, as shown in fig. 8, and six types of video laryngoscopes that we can see include three video laryngoscopes with channels (Airtraq, a.p. advanced difficult air way blade, KingVision) and three video laryngoscopes without channels (C-MAC D-blade, glidscope, McGrath). It can be seen that many laryngoscopes replace traditional metal throat pressure plate blades with friendly materials such as plastics or silica gel, but the shaping and the channel creating effects of these flexible material pressure plates are poor, effective channels cannot be established, and for the cleanness of neonate's oral cavity and depths than chicken ribs, metal pressure plates are commonly used clinically and have arc-shaped and straight plates, and the head of the neonate needs to be matched with a better angle. In view of the closure and mucosa adhesion applied in the early oral cavity stage of the newborn and the fragility of the pharyngeal passage, the relatively rigid structure has obvious damage to the newborn, and adverse events such as soft tissue damage or bleeding are common, so that a large psychological burden is brought to the operation of medical staff, and the success rate of laryngoscope intervention can be further influenced.
