Description

Anesthetic mask for patients with difficult airway

Technical Field

The utility model belongs to the technical field of the difficult air flue, concretely relates to anaesthetic mask that can be used to difficult air flue patient.

Background

Perioperative airway management is an important part of anesthesia management, and the control of the airway by an anesthesiologist is often closely related to the patient's life, however, in clinical anesthesia work, anesthetists often encounter various difficult airway challenges, and reports have shown that the incidence of difficult airways is as high as 1% -4%, about 30% of cases of anesthesia death are caused by serious difficult airway management failure, wherein the difficult ventilation of the patient is a more urgent situation, when the ventilation is difficult by holding the lower jaw, using the oropharyngeal airway or placing the laryngeal mask, in the emergency situation, when the doctor is under the condition of having more hands to cause the life of the patient to be in danger and the patient has the complications of excessive obesity, tongue hypertrophy, snore, apnea and the like, the patient often has difficulty in ventilation due to the fact that the throat cavity is narrow and the enlarged tongue body falls backwards, and the airway obstruction caused by the fact that the tongue body falls backwards cannot be relieved even if the lower jaw is simply supported.

When the difficult air flue appears in the patient, can't resume the air flue breathing in the short time because breathing is obstructed and can cause the patient oxygen deficiency, and this process of brain oxygen deficiency is irreversible, perioperative period or very troublesome problem in the medical treatment first aid when consequently the difficult air flue, and wear difficult air flue face guard for the patient during current answer method, but use operation such as intubate when simple change position or carry out outside the supplementary breathing of exerting pressure to the patient and can't play a role, and intubate uncertainty can cause the secondary injury to the patient, we propose an anaesthetic mask that can be used to difficult air flue patient based on this.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can be used to difficult air flue patient's anaesthetic mask, wear difficult air flue mask for the patient when having solved current reply method, but use operation such as intubate when simple change position or carry out outside the supplementary breathing of exerting pressure to the patient and can't play the effect, and intubate thing nondeterminacy can cause the problem of secondary injury to the patient.

In order to achieve the above object, the utility model provides a following technical scheme: an anaesthetic mask for patients with difficult air passage comprises a mask body and a mounting tube, wherein an inflating hose is fixedly mounted on the back surface of the mask body along the edge, one side of the front surface of the mask body is communicated with a threaded pipe, the other side of the front surface of the mask body is communicated with an air outlet pipe, the air outlet pipe is provided with an air outlet one-way valve, elastic bridles are fixedly arranged on both sides of the mask body, magic tapes are fixedly arranged at the ends of the elastic bridles, a soft front cover is fixedly arranged in the middle of the front surface of the mask body, the middle part of the soft front cover is communicated with an operation pipe, the interior of the operation pipe is provided with a thread groove, the end part of the operation pipe is movably provided with a soft plug, the outside of installation pipe is provided with the screw thread post and inserts and carry out threaded connection in the operation pipe, the one end fixed mounting of installation pipe has the gas channel pipe, the one end fixed mounting that the installation pipe was kept away from to the gas channel pipe has the taper pipe.
