Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to a funny breathing training device with positive end-expiratory pressure and oscillation. BACKGROUND

[0002] Due to long-term bedridden, mechanical ventilation or decreased ability of autonomous cough, severe patients often have airway clearance obstacles, which leads to sputum retention, and further increases the risk of airway obstruction, atelectasis and infection. How to effectively promote the discharge of airway secretions becomes the key to prevent and treat bronchial and pulmonary infections. According to the 2023 Expert Consensus on Airway Clearance Technology for Critically Ill Patients, the application of airflow oscillation, positive end-expiratory pressure (PEP) and other principles can effectively promote sputum discharge and improve airway patency. There are many respiratory training devices on the market to promote airway clearance, such as induced spirometer, Acapella, etc., which are widely used in the rehabilitation of patients with chronic lung diseases such as COPD and cystic fibrosis, and are clinically recognized for their economy and efficiency. However, these devices are mainly designed for general respiratory rehabilitation patients, and lack of optimized solutions specifically for severe patients, which has many limitations in clinical application.

[0003] Limitations of existing respiratory training devices in severe patients: 1. Lack of special design for severe patients, insufficient adaptability: current PEP respiratory training devices are mostly used for general patients, while severe patients often have special conditions such as consciousness disorders, cognitive impairment, tracheal intubation or tracheostomy, etc., which makes it difficult to ensure blood oxygen stability during training. The goal of respiratory training for severe patients is not only lung function recovery, but also respiratory muscle training, airway secretion clearance and oxygenation improvement, and the current devices lack sufficient integration of these functions.

[0004] 2. Single feedback mechanism, poor compliance: severe patients have low willingness for autonomous training, and existing devices lack interactive feedback such as visual, auditory or gamified incentive mechanisms, which makes the patient's use compliance low and affects the rehabilitation effect. Especially for children and long-term bedridden elderly patients, it is often difficult to adhere to training without interest, resulting in poor airway clearance effect.

[0005] 3. Insufficient infection control and cleaning maintenance: during the respiratory training process, the device may produce aerosol, increasing the risk of pathogen transmission, in addition, the structure of some devices is complex, the breathing valve and pipeline are not easy to disassemble, leading to retention of secretions and increasing the risk of cross infection.
