Abstract
Description
Technical Field
[0001] This utility model relates to the field of expectorant technology, and more specifically, to an oscillating positive expiratory pressure expectorant. Background Technology
[0002] Normally, an effective cough is sufficient to relax secretions and clear them from the body's airways. However, for people with more severe bronchial obstructions, such as collapsed airways, a single cough may not be enough to clear the obstruction. OPEP stands for Effective Bronchial Hygiene Technique for removing bronchial secretions from the body and is an important aspect of the treatment and ongoing care of patients with bronchial obstructions, such as those with chronic obstructive pulmonary disease (COPD). It is believed that the oscillation of expiratory pressure at the mouth during OPEP therapy effectively transmits oscillatory back pressure to the lungs, thereby separating obstructed airways and relaxing secretions that contribute to bronchial obstruction.
[0003] Currently available expiratory pressure expectorants on the market are mostly single-ball blocking structures, which have poor expiratory oscillation stability and cannot adjust the air pressure to suit the usage frequency of different patients. They also cannot effectively block water vapor during the blowing process, resulting in poor product durability. This utility model proposes a new solution to the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a solution to the technical problems mentioned in the background art.
[0005] To solve the above problems, the present invention adopts the following technical solution.
[0006] A positive expiratory pressure expectorant includes a grip shell with a working chamber inside. An airway is fixedly installed on the upper part of the grip shell, and a baffle plate is fixedly installed inside the airway. An air inlet is located on the upper surface of the grip shell corresponding to the position in front of the baffle plate. An air inlet pipe is fixedly installed below the air inlet, and an air nozzle is fixedly installed on one side of the end of the air inlet pipe. A oscillating box is located at the top of the air nozzle, and an oscillating plate is rotatably installed inside the oscillating box. A baffle block is located at the top of the oscillating plate, and the shape of the baffle block corresponds to the shape of the inner circumference of the air nozzle. A baffle block is located on the lower surface of the grip shell corresponding to the position below the oscillating box. A first air outlet is provided, and a second air outlet is provided in the working chamber above the oscillating box. An adjusting air pipe is fixedly installed below the second air outlet and is connected to the oscillating box. A mounting ring is fixedly provided on one end face of the adjusting air pipe, and a rotating shaft is rotatably connected inside the mounting ring. The top of the rotating shaft extends upward, passes through the upper end face of the grip shell, and extends into the air passage. An adjusting knob is fixedly installed on the top of the rotating shaft, and an adjusting hole is provided on one side of the adjusting knob. An air blowing tube is detachably inserted into the top of the air passage. A barrier cavity is provided inside the air blowing tube, and water vapor filter cotton is provided inside the barrier cavity.
[0007] Preferably, a diversion port is provided on one end face of the air intake pipe, and a diversion pipe is connected after the diversion port. The top end of the diversion pipe passes through the side end face of the grip shell. A transparent airflow indicator tube is fixedly installed at the top end of the diversion pipe. An indicator ball is provided inside the transparent airflow indicator tube, and a first one-way valve is provided at the top end of the transparent airflow indicator tube.
[0008] In any of the above embodiments, it is preferred that a button is provided on one end face of the grip shell, the end of the button extends into the oscillation box, and a button block is fixedly provided at the end of the oscillation plate corresponding to the button.
[0009] In any of the above embodiments, it is preferred that a second one-way valve is fixedly installed on the barrier plate.

[0011] In any of the above solutions, it is preferred that a plastic mesh is detachably installed on the first air outlet.
[0012] Compared with existing technologies, the advantages of this utility model are:
[0013] This invention provides an oscillating positive expiratory pressure expectorant. By incorporating an oscillating box within the working chamber and installing an oscillating plate therein, the oscillating structure, which separates the oscillating plate from the chamber, is more stable compared to the traditional single-ball blocking structure. The second air outlet, with its adjustable pressure via a knob and a transparent airflow indicator tube, allows for multi-level adjustment and pressure visualization. Furthermore, the inclusion of a water vapor filter in the blocking chamber effectively reduces the moisture content in exhaled air, increasing the product's lifespan. Attached Figure Description

The top end of the rotating shaft 15 extends upward, passes through the upper end face of the grip shell 1, and extends into the air passage 3. An adjusting knob 16 is fixedly installed on the top end of the rotating shaft 15. An adjusting hole 17 is provided on one side of the adjusting knob 16. An air blowing pipe 18 is detachably inserted into the top end of the air passage 3. A barrier cavity 19 is provided in the air blowing pipe 18.

[0023] In this embodiment, a diversion port 21 is provided on one end face of the air intake pipe 6, and a diversion pipe 22 is connected to the diversion port 21. The top end of the diversion pipe 22 passes through the side end face of the grip shell 1. A transparent airflow indicator pipe 23 is fixedly installed on the top end of the diversion pipe 22. An indicator ball 24 is provided inside the transparent airflow indicator pipe 23, and a first one-way valve 25 is provided on the top end of the transparent airflow indicator pipe 23.
[0024] In this embodiment, a button 26 is provided on one end face of the grip shell 1, and the end of the button 26 extends into the oscillation box 8. A button block 27 is fixedly provided at the end of the oscillation plate 9 corresponding to the button 26.

[0027] In this embodiment, a plastic mesh 30 is detachably installed on the first air outlet 11.
[0028] The working process of this utility model is as follows:
[0029] This invention allows patients to inhale air through the mouthpiece 29.

The working pressure can be adjusted by rotating the adjustment knob 16 to cover the second air outlet 12. During use, the position of the indicator ball 24 in the transparent airflow indicator tube 23 can be observed to determine the current air pressure. When it is necessary to measure the limit, the oscillating plate 9 is fixed by pressing the knob 26, and the maximum value is read by blowing air at full force, which can determine the peak pressure. Compared with the traditional structure, the design of oscillating box 8 in the working chamber 2 and oscillating plate 9 installed in it provides a more stable oscillation structure with the oscillating plate and the chamber separated. The design of the second air outlet 12, which can be adjusted by adjusting the air pressure through the knob 16, combined with the transparent airflow indicator tube 23, can realize multi-level adjustment and air pressure visualization. The design of water vapor filter cotton 20 in the barrier chamber 19 effectively reduces the water content in the exhaled air and increases the product's service life.
