Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly to a sputum drainage device for elderly patients with pulmonary infections. Background Art

[0002] Pulmonary infection is a common health problem among the elderly, especially those who are bedridden for a long time or have underlying diseases. They are more prone to pulmonary infections. After pulmonary infection, the accumulation of sputum not only aggravates the condition but may also trigger other complications such as pneumonia and atelectasis. Therefore, effective sputum drainage is crucial for the treatment and rehabilitation of elderly patients with pulmonary infections.

[0003] Traditional sputum drainage methods include physical therapy, drug treatment, and mechanical assisted sputum drainage, etc. However, these methods often have certain limitations. For example, the intensity of physical therapy is difficult to control, and excessive intensity may damage lung tissue; the effect of drug treatment is greatly affected by individual differences; mechanical assisted sputum drainage devices may not meet the specific physiological needs and comfort requirements of the elderly due to unreasonable designs.

[0004] Currently, although there are some sputum drainage devices for pulmonary infections on the market, most devices have the following problems. During the sputum drainage process, the sputum drainage device will generate a certain amplitude. When connecting the liquid storage bottle to the control box, the traditional method is to directly place the liquid storage bottle on one side of the control box without limiting its position. During the sputum drainage process, the liquid storage bottle will shake due to vibration. There are special structures for fixing the liquid storage bottle on the market, but the disassembly operation is relatively cumbersome, and it is not convenient for ordinary elderly people to disassemble. Therefore, there is an urgent need for a sputum drainage device for pulmonary infections that is designed specifically for the elderly, easy to operate, small in size, and has a tightly installed liquid storage bottle. Summary of the Invention

[0005] To overcome the existing problems, the embodiments of the present application provide a sputum drainage device for elderly patients with pulmonary infections. A fixing seat is provided at the intersection of the control box and the liquid storage bottle. A through groove is opened at the intersection of the fixing seat and the liquid storage bottle. A sliding groove is provided on the upper surface of the fixing seat located in the through groove. A limiting component slides inside the sliding groove. When connecting the liquid storage bottle to the fixing seat, the limiting component slides inside the sliding groove and is connected to the liquid storage bottle. Through the elastic force of the spring ring, it contacts the outer wall of the liquid storage bottle to provide a stable limiting force to ensure that the liquid storage bottle will not loosen or fall off during vibration.
