Portable intelligent auxiliary sputum excretion device

Abstract

The invention provides a portable intelligent auxiliary sputum excretion device. The device comprises a sputum excretion waistcoat (1), and a respiration sensor (5) is connected between the upper backportion of the sputum excretion waistcoat (1) and a pneumatic pulse generator (3); a control unit (6) is arranged on the pneumatic pulse generator (3); the waist portion of one side of the sputum excretion waistcoat (1) is connected with the pneumatic pulse generator (3) through a pulse blood oxygen sensor (4); the pulse blood oxygen sensor (4), the respiration sensor (5) and the sputum excretionwaistcoat (1) are integrally designed; the pneumatic pulse generator (3) and the sputum excretion waistcoat (1) are connected through an air guide flexible tube (2). According to a portable intelligent auxiliary sputum excretion method, the state of a patient is judged by collecting the respiratory frequency and the oxyhemoglobin saturation of the patient, and the sputum excretion waistcoat (1) vibrates and helps the patient to excrete sputum. According to the portable intelligent auxiliary sputum excretion device, automatic control cover the sputum excretion device is achieved, the device operation is simplified, and the labor intensity of medical personnel is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a portable intelligent auxiliary expectoration device. Background technique [0002] There are 43 million old chronic bronchitis patients in my country, a large part of them are weak and unable to expel sputum spontaneously, which causes blood circulation stasis in the lungs and increases the chance of complications such as lung infection and atelectasis. Therefore, timely start Device-assisted expectoration is important. [0003] Limitations of existing expectorant devices [0004] 1. Hand-held percussion and vibration expectoration machine, patients take prone, side, and sitting positions during treatment, which can effectively remove respiratory secretions, reduce lung moist rales, improve arterial blood oxygen saturation, promote inflammation dissipation, and prevent lung cancer. The occurrence and control of local infection and its further development. Its working intensit...

Problems solved by technology

[0005] 2. The high-frequency chest wall oscillation sputum expectoration instrument is small in size and is already a portable device, but the weight is still heavy

Its shortcoming is that the starting method is manual, and it cannot realize automatic starting, which has a greater distance from intelligence.

[0007] After analyzing the working principles and operation methods of three types of expectoration devices on the market, namely hand-held percussion and vibration expectoration devices, high-frequency chest wall oscillation expectoration devices and non-invasive expectoration devices, it is found that they all have poor portability. , unable to achieve automatic start and stop and other limitations
