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...

Embodiment 1

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

Embodiment 2

[0047] In Embodiment 1, the drive of the wind wheel 3 can also be realized by a motor, that is, to increase the drive motor 5 (such as figure 1 As shown in (a) and (c), when the wind wheels 3 are "parallel": the output shaft of the driving 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 wheels 3 are "connected in series" When: the "worm gear" gear transmission design can be used to realize the movement and power between the spatially interlaced axes, that is, the output shaft of the driving motor 5 is used as the driving worm to cooperate with the worm wheel set on the rotating shaft 6, so as to realize the wind wheel on the rotating shaft 6. 3; the drive motor 5 housing is fixed outside the resonant cavity 2; the rotating speed of the wind wheel 3 maintained by the drive motor 5 is guaranteed to be within the range of 960 / n to 1500 / n revolutions per minute (wherein n represents...

Embodiment 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 chamber 4, which can be screwed, buckled, glued, ultrasonic welded, Tether or any other way is sealed and fastened to the resonance chamber 2, and the cross-sectional area of ​​one end of the vibration amplification chamber 4 connected to the resonance chamber 2 is smaller than the cross-sectional area of ​​the other end, so the vibration amplification chamber 4 is an acoustic load for the resonance chamber 2, which will cause Some of the sound waves traveling this way are reflected, increasing the intensity of the sound waves entering the lung cavities. It can be seen that the effect of promoting the discharge of secretions in the airway is better in the device with the vibration amplification chamber 6 compared with the device without the vibration amplification chamber.
