Lung-clearing and sputum-expelling device for the elderly

Abstract

The invention discloses a lung-clearing and sputum-expelling device for the elderly, and relates to the technical field of respiratory medical instruments. The lung-clearing and sputum-expelling device for the elderly comprises a wearing unit, a vibration unit and a sputum suction unit. The wearing unit comprises a positioning plate and a wrapping garment surrounding the human chest; at that rearend of the position plate, a protection bag is arranged; a plurality of bag cavities are uniformly sewn in the protection bag; the bag cavity is filled with a shear thickening liquid; a plurality of threaded holes are arranged through the positioning plate; the vibration unit comprises a mounting pipe threadably connected with a threaded hole; an electromagnet is fixedly installed in the front part of the mounting pipe; a compression spring is fixedly connected with the rear end of the electromagnet; the rear end of the compression spring is fixedly connected with a knocking column; the sputumsuction unit comprises a tool table and a negative pressure pump; a rubber tube is uniformly connected with the periphery of the head of the sputum suction tube; the rubber tube is filled with magnetic powder. The invention has the beneficial effects of better protecting patients and transmitting vibration, enhancing airway stimulation and improving sputum expulsion treatment effect by using thecooperating of rapid high-frequency knocking and shear thickening liquid.

Description

technical field [0001] The invention relates to the technical field of respiratory internal medicine medical equipment. Background technique [0002] Diseases of the respiratory system lead to increased airway secretions. During the treatment process, many elderly and frail patients cannot rely on themselves to effectively expel sputum due to weakness and shortness of breath. Vibration can enhance the fluidity of secretions, improve the stimulation of coughing, and achieve the purpose of vibrating and expectoration. [0003] When the general percussion device forms an impact with the patient, the percussion head cannot fit the patient's body well, resulting in uneven force output, easy to cause pain, and cause discomfort to the percussion bone. In the process of sputum discharge, it will cause injury, and it will be impossible to strike for a long time in a better vibration percussion position, and at the same time, it will easily grind the skin and pull the nearby wound; a...

Problems solved by technology

[0003] When the general percussion device forms an impact with the patient, the percussion head cannot fit the patient's body well, resulting in uneven force output, easy to cause pain, and cause discomfort to the percussion bones. In the process of phlegm discharge, it will cause injury, and it will be impossible to strike for a long time at a better vibration percussion position, and at the same time, it will easily grind the skin and pull the nearby wound; adding a general elastic cushion will cause the vibration transmission to weaken, and The degree of fit of the elastic cushion cannot be guaranteed. At the same time, for the care of chest wounds, the deformation of the elastic material is easy to grind the skin and pull the wound; the general vibration expectoration relies on vibration to promote the flow of sputum in the airway to cause irritation, and the degree of irritation Weak and slow, while general external vibrations are sometimes ineffective in causing viscous sputum to flow
