Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a prone ventilation device. Background Technology

[0002] Severe pneumonia caused by respiratory infectious diseases is a common and critical respiratory illness characterized by complex etiology, rapid onset, rapid disease progression, high mortality, and poor prognosis. Although basic treatments, primarily anti-infection, respiratory support, and nutritional support, have achieved some success, the mortality rate remains high at 50%–76%. Prone ventilation, as an effective treatment strategy for acute respiratory syndrome, is now widely used in the clinical treatment of severe pneumonia, demonstrating significant efficacy in relieving respiratory distress and correcting hypoxemia.

[0003] Prone positioning ventilation refers to a treatment method that places the patient in a prone position for respiratory support, especially suitable for patients with severe pneumonia complicated by acute respiratory distress syndrome. Its core mechanism is to utilize gravity to improve the ventilation-perfusion mismatch in the lungs: in the supine position, the alveoli in the back collapse due to gravity, creating a state of "blood flow but no ventilation"; after changing to the prone position, the compressed alveoli re-expand, the ventilation area in the back increases, the pressure of the heart and mediastinum on the lung tissue is reduced, and sputum drainage to the large airways is promoted. This physiological change can significantly expand the effective ventilation area. Clinical observations show that the oxygenation improvement rate can reach over 70%, and blood oxygen saturation usually increases by 5%-10% within 1 hour after changing position. Authoritative guidelines at home and abroad clearly recommend prone positioning ventilation. For moderate, severe, and critically ill patients with high-risk factors for severe illness and rapid disease progression, standardized prone positioning therapy should be given, with a recommendation of no less than 12 hours per day. This recommendation is consistent with international research conclusions, showing that early implementation of prone positioning ventilation can significantly reduce the 28-day mortality rate.

[0004] In clinical practice, prone ventilation, as a key treatment for improving oxygenation, often requires patients to maintain a prone position for several hours daily to achieve the desired therapeutic effect. However, in practice, many patients cannot achieve the required duration of prone positioning. Prolonged prone positioning makes it difficult for patients to perform basic physiological activities such as expectoration and drinking. Furthermore, the lack of effective entertainment or information access during treatment, such as using mobile phones, further exacerbates discomfort and boredom. Existing prone support devices often lack sufficient flexibility and adjustability, making it difficult to accurately adapt to the differences in height and body type among patients. This "one-size-fits-all" design forces many patients into ergonomically unsuitable postures, increasing local pressure points and causing pain or numbness. These factors combined result in a significant decrease in patient comfort during treatment. This persistent discomfort directly weakens patients' willingness and ability to persist with treatment. Because patients cannot tolerate prolonged prone positioning, their actual daily prone ventilation time often fails to meet the clinically required target value. This not only affects the immediate effectiveness of treatment but also diminishes the overall expected therapeutic benefits of prone ventilation. Furthermore, during prone breathing, aerosols produced when patients with severe pneumonia caused by respiratory infectious diseases cough up sputum are released into the air, posing a risk of infection to others.
