Efficiency evaluation system for noninvasive ventilation equipment

Abstract

The invention relates to an efficiency evaluation system for noninvasive ventilation equipment. The system comprises a human three-dimensional head model, a simulated trachea, an active simulated lung and a processing unit, wherein one end of the simulated trachea is communicated with a month-nose channel in the three-dimensional head model, and the other end is communicated with the active simulated lung; the three-dimensional head model comprises a hard skeleton layer, a pressure sensor layer and an elastic cladding in sequence from inside to outside; a flow sensor for detecting actual flow entering the active simulated lung is arranged on the simulated trachea; the pressure sensor layer, the flow sensor and the active simulated lung are all communicated with the processing unit. The efficiency evaluation system for noninvasive ventilation equipment evaluates the comfort and the ventilation effectiveness when human face wears the noninvasive ventilation equipment in combination with the three-dimensional anatomic structure feature of human head and the real breathing condition of lungs, and finally evaluates the efficiency of the equipment, thereby providing a help for setting and ventilation mode of the noninvasive ventilation equipment.

Description

technical field [0001] The invention belongs to the field of equipment detection, and in particular relates to a non-invasive ventilation equipment work efficiency evaluation system, which is used to detect the comfort of the head and face and the effectiveness of ventilation of the wearer of the non-invasive ventilation equipment during use. Background technique [0002] Non-invasive ventilation is an effective means of life protection and disease treatment. In clinical practice, the incidence of respiratory diseases is increasing year by year, and the proportion of respiratory diseases such as chronic obstructive pulmonary disease and sleep apnea syndrome continues to increase. Non-invasive ventilation has become an effective treatment method. For high-altitude flight protection, non-invasive positive pressure ventilation is required to ensure the oxygen supply of the pilot's body. Many users need long-term non-invasive ventilation for life support and chronic disease tre...

Problems solved by technology

However, due to various factors such as technical limitations, design, and individual differences, some non-invasive ventilation equipment may make patients feel uncomfortable during ventilation

In the process of non-invasive ventilation, the user needs to wear the interface device of the non-invasive ventilation equipment on the head and face. To ensure the ventilation effect, the fixing belt of the interface device usually needs to be tightened, which will generate local pressure on the head and face and affect the comfort of non-invasive ventilation.

The comfort of the user's head and face is closely related to the ventilation process, which will cause short-term high pressure in the interface during the ventilation process, which may aggravate the local force and reduce the comfort of the non-invasive ventilation process

If the head and face are not compressed in order to ensure the comfort of wearing a non-invasive ventilation interface, there may be a risk of air leakage
