Description

Detection device and breathing machine

Technical Field

The disclosure relates to the technical field of respiration, in particular to a detection device and a respirator.

Background

The breathing machine is a medical device which can replace, control and change normal physiological breathing of people, increase the ventilation quantity of lungs, improve the respiratory function, reduce the respiratory consumption and save the heart reserve capacity. The breathing machine is used as first-aid equipment, is widely applied to clinical departments in large and medium hospitals at present, and is also equipment with highest clinical risk in all medical equipment types.

A ventilator is a high risk medical device whose safety and effectiveness in clinical use is directly related to the life safety of a patient. The method has the advantages that the effective quality control is implemented on the breathing machine in the using link, the quality problems and hidden dangers found are detected regularly and processed in time, the safety and reliability of the clinical application of the breathing machine are improved, and the method is a basic requirement of clinical first aid. How to quickly confirm the core performance parameters of the breathing machine at the emergency site and ensure that key safety indexes meet the clinical requirements of site emergency has become a problem to be solved by hospital medical staff and clinical medical engineering technicians.

The on-site rapid technology of the breathing machine aims to solve the problems of effectiveness, usability and rapidness of detection. Validity refers to the fact that a test item for rapid detection of a ventilator should cover core parameters, key functions and common faults of the ventilator, which need to be confirmed and optimized through big data analysis technology in combination with clinical application. Ease of use should take into account that on-site rapid detection of ventilators is often performed by medical personnel rather than by detection professionals, and that simplifying the test procedure and guiding proper operation is required. The quick detection has higher requirements on the timeliness and the rapidness of the detection. Currently, there is no mature solution for on-site rapid detection of ventilators.

Particularly at emergency sites, regular (weekly/monthly) safety confirmation of the ventilator prior to use is more necessary, which requires that the medical institution itself should be provided with on-site rapid detection capabilities of the ventilator.
