Positive pressure ventilation mask for respiratory department

Abstract

The invention discloses a positive pressure ventilation mask for respiratory department. The positive pressure ventilation mask structurally comprises a nasal cavity intubation mask groove, a thick ring buckling groove, a trapezoidal mask cap groove, a neck sleeve binding belt, an auxiliary frame plate and a forehead frame belt. The positive ventilation operation effect of applying the nasal cavity intubation mask groove to cooperate with the trapezoidal mask cap groove to form rotational flow pressure relief in a nasal cavity rotational flow annular through pipe, is achieved. The operation effect that the breathing mask realizes stable conveying of the air displacement amount and the air suction amount is guaranteed through follow-up vibration isolation pressing plate cushion protection and butt joint of the rotational flow annular through pipe and a trapezoidal shell cover, so that breathing lung alveolar continuous activity rehabilitation auxiliary air inlet exercise is promoted, apatient of the pneumology department is efficiently rehabilitated after an operation, and the nasal cavity dredging amount is continuously and efficiently adjusted; and the negative pressure amount ofa wheel ring is reduced, and the stability of positive pressure ventilation and the lung breathing uniformity are guaranteed.

Description

technical field [0001] The invention relates to a positive pressure ventilation mask for respiratory department, which belongs to the medical field. Background technique [0002] Patients in the Department of Respiratory Medicine need rehabilitation training for lung breathing operations after surgery. At this time, positive pressure ventilation masks are inserted to ensure the smoothness of the airway, improve oxygen delivery and breathing activity, ensure the recovery of alveoli, and improve the recovery efficiency of lung breathing volume. To ensure the high efficiency of the ventilator docking mask to conduct the nasal cavity and the throat cavity, the shortcomings of the current technology that need to be optimized are: [0003] The oxygen delivery mask of the respiratory department has a large amount of negative pressure on the patient's nasal cavity, and positive pressure adjustment is required to ensure the discharge of the ventilation mask and the supply of lung bre...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a positive pressure ventilation mask for the respiratory department to solve the problem that the oxygen delivery mask of the respiratory department has a large amount of negative pressure on the patient's nasal cavity, and positive pressure adjustment is required to ensure the discharge volume and auxiliary pressure of the ventilation mask. When the patient sleeps, the supply of lung breathing will cause positive and negative pressure collision conduction, resulting in excessive pressure difference in the airway, which will affect the activity of alveolar inflation, resulting in long-term dryness of the alveoli and short-term suffocation of the patient. The recovery period of postoperative equipment becomes longer, and there is no problem of promoting recovery efficiency
