Technical Field

The utility model belongs to the technical field of the medical treatment technique and specifically relates to a flexible laryngeal mask is freely adjusted to crooked length.

Background

The laryngeal mask is a tool for maintaining the breath of a patient during an anesthesia operation, and is called a three-major respiratory tract tool together with a mask and a tracheal cannula. The laryngeal mask has the advantages of simple and rapid implantation, small wound and the like, can be used as an air breather and a guide tube of a tracheal cannula, and is commonly used for short-term operations of mammary gland, head, neck, jaw, face and the like. The airway tube of conventional laryngeal masks is rigid or pre-formed and may serve as a handle when the mask is placed. However, once the laryngeal mask is placed, the ventilation tube is also fixed, the part of the ventilation tube extending out of the mouth is close to the operation area, which often affects the operation, and the arm of the operator often touches the outer part of the mouth of the ventilation tube inadvertently, which causes the displacement of the laryngeal mask to affect the ventilation, and the position of the laryngeal mask needs to be adjusted again. The soft ventilation pipe is soft, so that the position of the ventilation pipe can be adjusted, the ventilation pipe is prevented from interfering with an operation, but the soft ventilation pipe can cause difficulty in placing the laryngeal mask, and therefore the bendable laryngeal mask with the freely adjustable bending length is provided for solving the problems.
