Three-head multifunctional laryngeal mask special for trachea operation

Abstract

The invention relates to the technical field of medical laryngeal masks, and discloses a three-head multifunctional laryngeal mask special for a trachea operation. The three-head multifunctional laryngeal mask comprises a connecting pipeline and a multifunctional laryngeal mask, wherein the right upper end of the connecting pipeline is spliced with the multifunctional laryngeal mask; the connecting pipeline comprises a pipe cavity a and a pipe cavity b; a flexible pipe a is spliced in the pipe cavity a; a flexible pipe b is spliced in the pipe cavity b; the right side of the flexible pipe b isprovided with an air duct; the lower ends of the flexible pipe b and the air duct are fixedly connected with a dual-purpose through connection pipe; and the right upper end of the air duct is splicedinto the right lower end of the multifunctional laryngeal mask. When the three-head multifunctional laryngeal mask special for the trachea operation is used, a slightly-convex surface and a reinforcing rib can effectively reinforce the toughness of the multifunctional laryngeal mask in a use process, and a situation that the multifunctional laryngeal mask is folded due to reasons, including operation skills and the like so as to cause insertion failure, the pipe needs to be pulled out and repeatedly inserted and therefore, the throat position of a patient is injured can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical laryngeal masks, in particular to a three-head multifunctional laryngeal mask for airway surgery. Background technique [0002] The laryngeal mask was developed by British doctor Brain on the basis of the anatomical structure of the adult throat. The first and second generation laryngeal masks have many advantages: (1) easy to use, and can quickly establish an artificial airway; (2) high success rate of placement, The success rate of untrained medical personnel is 87%, and the total success rate is 99.81%; (3) Reliable ventilation; (4) Avoid throat and tracheal mucosal damage; (5) Small stimulation and small cardiovascular response; (6) Available for first aid. However, the traditional first- and second-generation laryngeal masks have incomplete seals with the respiratory tract, increased oral secretions, and are easy to shift. They cannot effectively isolate the respiratory tract and digestive t...

Problems solved by technology

[0003] For example, the patent No. CN103596613A provides a laryngeal mask that can correctly ensure the airway with simple operations. part (5b) of the base end portion and the distal portion formed with the ventilation opening, and formed with a communication path connecting the first connecting portion (5b) and the ventilation opening; the annular sleeve (7), based on the annular When the cuff is inserted into the specified insertion position, it expands and can be closely attached to the patient's trachea opening; the hyoid bone abutment parts (6d), (6e) protrude laterally from the outer tube (4a) to form an annular When the sleeve (7) is inserted into the insertion position, it abuts against the patient's hyoid bone (J7) from above in the patient's pharynx (T); although the invention of the laryngeal mask can protect the airway It is not harmed, but the functions are still not rich enough. In actual operation, the laryngeal mask may leak air in the later stage due to improper insertion position or operation method. The fixed position is easy to be displaced due to accidental touch. Improper technique, the different size of the patient's throat, etc. may easily cause the laryngeal mask to bend, so it needs to be pulled out, and repeated insertion may cause damage to the patient's throat
