Auxiliary discharge device of secretion in airway

Abstract

The invention provides an auxiliary discharge device of secretion in an airway. The auxiliary discharge device comprises an air blowing nozzle, a resonance tube and wind wheels, wherein the air blowing nozzle is tightly connected with a resonance cavity in a sealed mode, and the wind wheels are rotationally installed in the resonance cavity in a parallel connection or series connection mode; the device further comprises a driving motor; when the wind wheels are connected in parallel, an output shaft of the driving motor is inserted into a central through hole of the wind wheels and fixed, andwhen the wind wheels are connected in series, the output shaft of the driving motor serves as a driving worm and is matched with a worm wheel arranged on a rotating shaft; the device further comprisesa vibration amplifying cavity tightly connected with the resonance cavity in a sealed mode. The device only needs a small amount of low-speed air to flow into a resonance cavity pipeline to cause therotation of the wind wheels, and the rotation frequency or the frequency multiplication of the wind wheel has a harmonic component of 16-25Hz, so that the device is not only suitable for general adults, but also suitable for young children and old and weak people; the device is simple in structure, low in cost, convenient to operate and carry and good in using effect.

Description

technical field [0001] The invention belongs to the technical field of auxiliary medical devices, and in particular relates to an auxiliary discharge device for secretions in the airway. Background technique [0002] Respiratory diseases are common diseases and frequently-occurring diseases of human beings, which endanger human health. The accumulation of sputum will bring harm to the body, and provide a breeding environment for bacteria in the respiratory tract, leading to the deterioration of inflammation, which will lead to secondary infection and airway damage, so it is especially important for airway care. The discharge of airway secretions is the core of airway care. [0003] Existing airway sputum discharge methods mainly include: 1. Manual knocking on the back to expel sputum. This method needs the assistance of the operator, and the patient is asked to lie down (change among the 12 postures specified), and the operator adopts the correct The technique and strength...

Problems solved by technology

[0003] Existing airway sputum discharge methods mainly include: 1. Manual knocking on the back to expel sputum. This method needs the assistance of the operator, and the patient is asked to lie down (change among the 12 postures specified), and the operator adopts the correct The technique and strength, moving, tapping and tapping the chest and back at a certain frequency, so that the entire lungs can be completely treated by flapping. This method needs to last for 40-50 minutes, and is performed 1-4 times a day, sometimes accompanied by drug inhalation In order to better discharge the airway secretions, it not only consumes a lot of manpower but also has a general effect

2. The pressure gas pulse is introduced into the airway through the mouth. This method may cause danger under higher air pressure, such as barotrauma such as alveolar rupture, and the risk factor is relatively large.

3. Use 18Hz sound waves to vibrate the lungs. Since the peristaltic frequency of cleaning cilia in the airway of the human body is about 18Hz, using 18Hz sound waves to vibrate the lungs will increase the power of cilia peristalsis. This method will not generate high-pressure airflow, but traditional The method requires higher energy to obtain low-frequency sound waves, usually the loudspeaker component is used as a high-dynamic sound source to vibrate the airway; however, the high-dynamic sound driver has a short service life and is expensive and not easy to carry
