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 airw

Example Embodiment

[0026] Example 1

[0027] Such as figure 1 As shown in (a), (b), (c), the airway secretion auxiliary discharge device disclosed in this embodiment includes a blowing nozzle 1, a resonance cavity 2 and a wind wheel 3; the blowing nozzle 1 and the resonance cavity 2 can be The connection is sealed and fastened by threads, snaps, gluing, ultrasonic welding, lacing or any other means; the wind wheel 3 can be installed in the resonant cavity 2 through a shaft, a sliding groove or other rotatable ways; the resonant cavity 2 It is a tubular structure, and the cross-sectional shape can be round, rectangular, elliptical or any other shape, such as figure 1 As shown in (c), the inner wall of the resonant cavity 2 is also provided with a number of hydrophobic prismatic structures 2-1, which are used to guide the water vapor and air flow generated during the outflow process to avoid condensation of water vapor on the inner wall of the resonant cavity 2. In this embodiment, the cross section ...

Example Embodiment

[0046] Example 2

[0047] In Embodiment 1, the drive of the wind wheel 3 can also be realized by a motor, that is, a drive motor 5 (such as figure 1 (a) and (c)), when the wind wheel 3 is "parallel": the output shaft of the drive motor 5 is inserted into the center through hole of the wind wheel 3 and fixed to ensure that the two do not rotate relative to each other; the wind wheel 3 is "in series" Time: Through the "worm gear" gear transmission design, the movement and power between the spatially interleaved shafts can be realized, that is, the output shaft of the drive motor 5 acts as a drive worm to cooperate with the worm wheel set on the rotating shaft 6, thereby realizing the wind wheel on the rotating shaft 6 3 rotation; the housing of the drive motor 5 is fixed outside the resonance cavity 2; the continuous rotation of the wind wheel 3 is maintained by the drive motor 5 to ensure that the speed is within the range of 960 / n~1500 / n revolutions per minute (where n represents ...

Example Embodiment

[0051] Example 3

[0052] Such as figure 1 As shown in (a), (b), and (c), in addition to the structures in Embodiments 1 and 2, the device disclosed in this embodiment also includes a vibration amplification cavity 4 that can be screwed, snapped, glued, ultrasonically welded, Tie or any other means are tightly and tightly connected to the resonant cavity 2. The cross-sectional area of ​​one end of the vibration amplifier 4 and the resonant cavity 2 is smaller than the cross-sectional area of ​​the other end. Therefore, the vibration amplifier 4 is an acoustic load to the resonant cavity 2 and will cause Part of the sound waves propagating here is reflected, which increases the intensity of the sound waves entering the lung cavity. It can be seen that the device with the added vibration amplification cavity 6 has a better effect of promoting the discharge of secretions in the airway than the device without the vibration amplification cavity.

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...
