China's ventilator market size grew from 5.58 billion yuan in 2014 to 11.61 billion yuan in 2018, with a CAGR of 20.1%. In the field of medical ventilators, the market size of the industry continued to grow from 1.176 billion yuan in 2012 to 2.43 billion yuan in 2018, with a CAGR of 12.86%.
Ventilator is essentially a kind of ventilation machine, used to replace, control or change the normal physiological respiration of human beings, increase pulmonary ventilation, improve respiratory function, reduce respiratory function consumption device. As an effective means to artificially replace autonomous ventilation, ventilators have been widely used in the following three major fields: (1) respiratory failure caused by respiratory diseases, such as chronic obstructive pulmonary inflammation, lung infections, asthma, etc.; (2) surgical procedures, including respiratory management during anesthesia for major surgeries, and postoperative ventilation support for pediatric surgeries, etc.; and (3) sleep apnea, such as snoring, sleep apnea and other sleep disorders.
Ventilators are divided into many varieties and widely used, and there are various classifications according to different situations, and the most important classification is mainly invasive and non-invasive ventilators according to different connection methods. The most important categories are invasive and non-invasive ventilators based on the type of connection. Depending on the user group, the type of connection, the functional use, and the type of drive, ventilators can be categorized into adult ventilators, infant ventilators, invasive ventilators, and non-invasive ventilators.
Ventilators need to be distinguished from the more common oxygen concentrators. Ventilators are used to assist breathing by applying different pressures to help open the airway and keep it open so that the patient can breathe normally. Oxygen concentrator is mainly used to produce oxygen, no ventilator function, also can not produce a lot of pressure to help patients to improve ventilation, the working principle is to use molecular sieve physical adsorption and desorption technology to deal with the nitrogen in the air so as to get high purity of oxygen, and then through the nasal catheter or oxygen mask to the patient's body, the patient's condition is not serious, you can use the oxygen concentrator alone oxygen to improve oxygen levels, if the patient's condition is more serious, or carbon dioxide retention and respiratory problems, the patient can also be used as a means to help patients to maintain a smooth airway, so as to achieve normal breathing. If the patient's condition is more serious, or if there is carbon dioxide retention or respiratory distress, then the combination of an oxygen concentrator and a ventilator is required.
Ventilators have a variety of functions and applications. Ventilators are commonly used in general hospitals, specialty hospitals, private hospitals, rehabilitation centers and other medical institutions, as well as emergency rooms, ambulances, and home care. Medical ventilators are mainly used in medical institutions, with invasive and non-invasive types, further subdivided into therapeutic, emergency and transportation types, etc. The functions of medical ventilators are complicated and diversified, and they can be used for clinical rescue and treatment of acute and chronic respiratory failure or respiratory insufficiency caused by various reasons. Home ventilators (non-invasive) are divided into three types: life-supporting, non-life-supporting, and sleep apnea treatment equipment. Life-supporting types provide or increase pulmonary ventilation for patients who rely on ventilators; sleep apnea treatment equipment is suitable for snoring, obstructive sleep apnea syndrome, etc.; and non-life-supporting types are suitable for the treatment of apnea syndrome as well as for the treatment of heart disease and respiratory failure, In addition to apnea syndrome, the non-life support type is also suitable for the treatment of pulmonary heart disease, respiratory failure, chronic obstructive pulmonary disease, motor neuromuscular weakness and other mild respiratory disorders.
Medical ventilators, also known as mechanical ventilation, can be subdivided into non-invasive mechanical ventilation (NIV) and invasive mechanical ventilation (IMV), i.e., non-invasive ventilators and invasive ventilators. Non-invasive ventilators supply oxygen through a closed mask worn over the patient's face, and are used primarily for conscious, spontaneously breathing patients, while invasive ventilators require incision of the patient's windpipe to supply oxygen directly to the patient's lungs, and are usually used for patients with severe respiratory failure.
Ventilators are significant in the treatment of patients with new crowns. According to a clinical study published in The Lancet of 99 patients with neocoronavirus at Wuhan Jinyintan Hospital, 11 of the patients who died had varying degrees of respiratory distress syndrome and severe infections, accompanied by liver damage, kidney failure and other symptoms. Studies have shown that the neocoronavirus is extremely “aggressive” towards the lungs of infected patients. When the neocoronavirus targets the lungs of patients, causing complications such as pneumonia and acute respiratory distress syndrome, the only way to ensure the oxygen level of the patient is to use a ventilator to assist or replace the breathing, to avoid respiratory and vital organ failure, and to buy time for more clinical treatments. The only way to ensure the patient's blood oxygen level is to use ventilator-assisted or alternative respiration to avoid respiratory and vital organ failure and to buy time for more clinical treatment. In the Diagnostic and Treatment Program for New Coronary Virus Pneumonia (Trial Version 7) issued by the National Health Commission, it is mentioned that non-invasive or invasive mechanical ventilation is one of the important diagnostic and treatment methods for respiratory support in severe and critical cases.
According to a joint study conducted by Tongji Hospital of Huazhong University of Science and Technology and other hospitals, the use of non-invasive or invasive mechanical ventilation is one of the important treatment methods.
