Description
Technical Field
The utility model belongs to the technical field of the breathing machine, concretely relates to two horizontal breathing machines are with adjusting device that admits air.
Background
The double-level respiratory therapeutic apparatus is composed of a small-sized air compressor (fan), a control circuit, a fan bin, a pressure sensor, a flow sensor, a humidifier, a water tank, an airflow output conduit, a nasal mask and the like.
The machine maintains the set output pressure according to the preset pressure, applies the preset output pressure to the upper respiratory tract of the patient through the pipeline and the nasal mask, keeps the upper respiratory tract of the patient open and unobstructed, and eliminates the snoring, the hypoventilation and the sleep apnea. Bi-level ventilators provide high pressure when you inhale, called IPAP (inspiratory positive airway pressure); low pressure is provided during exhalation, known as EPAP (positive airway pressure during exhalation). High pressure will make inhalation easier, while low pressure will make exhalation smoother.
The problems existing in the prior art are as follows: when the fan normally runs, the rotating speed of the motor can be more than 1 ten thousand revolutions per minute, and the maximum air flow rate can reach 200 liters per minute. High speed operation of the motor will produce vibrations, and high speed airflow will also produce noise.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two level breathing machine are with adjusting device that admits air, simple structure, convenient operation.
The utility model provides a following technical scheme: the utility model provides a two level breathing machine are with adjusting device that admits air, includes lower cover and upper cover, the piece is placed to the lower cover in-connection has the fan, the fan is placed about the piece end connection have the shock attenuation piece, the fan is placed and is equipped with first air inlet (5) and first gas outlet on the piece, the fan is placed an in-connection and is had spiral air flue, spiral air flue keeps away from first air inlet one side and is connected with direct trachea, one side that first air inlet was kept away from to direct trachea is equipped with the venthole, the venthole is connected with the pipeline of giving vent to anger, the inner wall that the piece was placed to the fan is connected with damping sponge.
Preferably, the spiral air inlet of the spiral air passage is in a horn shape, and one side with a large caliber faces the first air inlet.
Preferably, the air outlet of the air outlet pipeline corresponds to the first air outlet.
Preferably, the top wall is connected with a cochlear air inlet.
The utility model has the advantages that: noise generated when the fan operates at high speed can be reduced, and vibration generated when the motor operates at high speed can be damped.
