Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a high-frequency chest wall oscillation inflatable vest without lateral tenderness. Background Art

[0002] Phlegm is mucus secreted by the respiratory tract. When people suffer from respiratory tract inflammation, they are often accompanied by coughing. Coughing is a defensive reaction of the human body. Coughing can expel phlegm and keep the respiratory tract clean and unobstructed. When suffering from tracheitis and there is a lot of phlegm, it is necessary to cough it out in time, otherwise it will induce respiratory tract obstruction and cause pneumonia.

[0003] The high-frequency chest wall oscillation expectoration device consists of a pneumatic pulse generator, an inflation hose, an inflatable vest and an emergency stop switch. The system inflates and deflates the vest at high speed through two air guide hoses connected to the inflatable vest. When the frequency reaches a certain level, the chest cavity wrapped in the vest will oscillate, similar to a slight cough. This high-frequency whole-chest oscillation technology simulates the chest wall oscillation caused by coughing, relaxes and liquefies the mucus and metabolites on the surface of the expiratory tract mucosa, makes them smaller and looser and falls off. When the sputum moves from the bronchi to the main trachea, it is expelled from the body through coughing or artificial suction.

[0004] The inflatable vests in the prior art are fully enclosed, so not only the front and back sides are compressed and vibrated, but also the left and right sides are compressed and vibrated. Therefore, they cannot meet the needs of patients who have undergone thoracic surgery, minimally invasive lung surgery, etc. The fully enclosed high-frequency chest wall oscillation inflatable vests in the prior art will cause harmful compression to the side wound during use.

[0026] The airbag assembly includes multiple side air tubes, a front airbag 2 and a rear airbag 4. The front airbag 2 is connected to the inner side surface of the front jacket 1. Specifically, the front airbag 2 can be inserted into the first accommodating cavity from the zipper 16. The front airbag 2 is provided with buckle parts 23 at four edge positions respectively, and the inner side surface of the front jacket 1 is also provided with first snap buttons 14 at the corresponding positions. The front airbag 2 is connected to the front jacket 1 through the snap-fastening of multiple first snap buttons 14 and the buckle parts 23. The rear airbag 4 is connected to the inner side surface of the rear jacket 3. The rear airbag 4 can be inserted into the second accommodating cavity from the zipper 36. The rear airbag 4 is provided with buckle parts 43 at four edge positions respectively, and the inner side surface of the rear jacket 3 is also provided with second snap buttons 34 at the corresponding positions. The rear airbag 4 is connected to the rear jacket 3 through the snap-fastening of multiple second snap buttons 34 and the buckle parts 43.

[0027] The front airbag 2 is provided with two airbag nozzles 22, and the two airbag nozzles 22 are distributed along the horizontal left-right direction Y and are located on the lower side of the front jacket 1. One airbag nozzle 22 passes through one positioning hole 12.

A wearing position is formed between the front airbag 2 and the rear airbag 4. The wearing position is used for the user to wear. The wearing position runs through along the horizontal left-right direction Y and forms side openings on both sides respectively. The two airbag nozzles 22 are used to connect with two air guide tubes of the high-frequency chest wall oscillation sputum drainage instrument, and then form an air chamber loop.

[0028] A side trachea is located at one side opening and communicates between the front airbag 2 and the rear airbag 4. The side trachea on one side passes through the first opening 15 and the second opening 35 on the corresponding side.

In this embodiment, the sum S1 of the cross-sectional areas of the multiple single-side side tracheas is greater than the cross-sectional area S2 of a single airbag nozzle 22. In this way, the front airbag can be inflated and deflated reciprocally at a high speed. When the frequency reaches a certain level, it will cause the chest cavity wrapped by the front and rear airbags to oscillate. At the same time of oscillation, the position of the side chest wound is also avoided, meeting the needs of patients who have undergone thoracic surgery, minimally invasive lung surgery, etc. on the side chest. And, the air chamber volume of the rear airbag 4 is greater than the air chamber volume of the front airbag 2. In actual application, at least two thermal indentations 24 can be arranged in the air chamber of the front airbag 2. Through the control of the length, thickness and width of the thermal indentations 24, the air chamber volume of the front airbag 2 can be adjusted.
