Laryngeal mask fixing band with good fixing effect

Abstract

The invention discloses a laryngeal mask fixing band with a good fixing effect, belongs to the technical field of clinical medical instruments, and is used for effectively fixing a laryngeal mask. The technical scheme is that the laryngeal mask fixing band is composed of a front fixed surface, a lower fixed surface and a fastening band, wherein the front fixed surface covers cheeks on two sides, an oral cavity, an upper lip and a lower lip; the lower fixed surface covers a lower jaw; the front fixed surface and the lower fixed surface are smoothly and integrally connected; after being respectively connected to the two ends of the front fixed surface, the fastening band encircles a head backwardly to be connected; a laryngeal mask fixing hole is formed in the front fixed surface; the position of the laryngeal mask fixing hole is corresponding to the oral cavity; the diameter of the laryngeal mask fixing hole is matched with the diameter of a laryngeal mask pipe. The laryngeal mask fixing band is simple and practical in structure and good in fastening effect; an effective medical instrument is provided for patients and medical workers; a clinical problem which is not solved for a long time is solved; a blank in laryngeal mask clinical fixation at home and abroad is filled; promotional and use values and obvious social benefits are achieved.

Description

technical field [0001] The invention relates to a device for fixing a ventilator laryngeal mask commonly used in medical clinics, and belongs to the technical field of clinical medical devices. Background technique [0002] The laryngeal mask is a special type of ventilation tube, which is mainly composed of an air guide tube, an annular air bag and an inflatable tube. The annular airbag connected to the front end of the airway can just cover the larynx when inflated, so it is called the laryngeal mask ventilation tube. After several generations of technological improvement, the laryngeal mask has the advantages of simple operation, high success rate of insertion, stable hemodynamics during insertion, and less stimulation to patients. It is gradually being used in clinical anesthesia and pre-hospital first aid. [0003] After the laryngeal mask is successfully placed, its open end is facing the opening of the trachea. The inflated mask body is close to the tissue around the...

Problems solved by technology

However, clinically, due to various factors such as surgical operations and patients, its position is relatively unstable, and it is easily affected by changes in the patient's position and surgical operations during surgery, especially for the elderly, whose oral and maxillofacial muscles are loose. During the process, due to changes in body position, the oral tissue and muscles around the laryngeal mask often shift, resulting in a change in the position of the laryngeal mask. After the position of the laryngeal mask is changed, the ventilation function may decline, and in severe cases, airway obstruction may occur, endangering the patient's life.

[0004] The traditional way of fixing the laryngeal mask is tape, but the effect of tape fixing is not good, especially for the elderly, it is more difficult to fix the laryngeal mask

Most of the elderly have dentures and the oropharyngeal muscles are loose. After the dentures are removed during surgery, the tape fixation loses its support, making it difficult to implement the fixation. Therefore, it is often necessary to use multiple tapes to lift the mandible to the top of the head to reduce the Oral space, enhance the airtightness of the laryngeal mask, the method of fixing the laryngeal mask with tape is complicated to operate, cumbersome to remove, and unsightly
