Technical Field
The utility model belongs to the technical field of respiratory protection equipment, especially, relate to a mouth nose disconnect-type respirator.
Background
At present, noninvasive positive pressure ventilation refers to positive pressure auxiliary ventilation which is carried out by connecting a patient with a breathing machine in a noninvasive mode such as a nasal mask, an oronasal mask or a full face mask, and the like, is one of the commonly used auxiliary ventilation methods in the department of respiration, the department of emergency treatment and the department of critical medicine, can reduce the tracheal intubation rate of the patient, and is mainly suitable for patients with acute respiratory failure, particularly patients with carbon dioxide retention.
Although noninvasive ventilators are widely used clinically, certain complications exist, and abdominal distension is one of the common complications. In the clinical use process, the discomfort caused by positive pressure ventilation is relieved by frequently breathing through mouth in the process of using a noninvasive ventilator to part of acute respiratory failure patients, so that high-pressure gas enters the gastrointestinal tract through the oropharynx, the abdominal distension of the patients is caused, especially for the respiratory failure patients who partially reject tracheal intubation, the nasal breathing is difficult to achieve in the process of using the noninvasive ventilator to assist ventilation, so that a large amount of gas enters the stomach intestine, the abdominal distension of the patients is obvious, and the risk of inhalation pneumonia of the patients is increased. At present, the common masks at home and abroad are a nose mask and an oral-nasal mask.
Through the above analysis, the problems and defects of the prior art are as follows: (1) the nose mask is more comfortable to use and easy to accept by patients, but in the actual treatment process, because the respiratory frequency of the patients is fast, the patients can not correctly realize the mouth closing and nose breathing, the mouth leakage is caused, and the failure of positive pressure ventilation treatment is often caused.
(2) The oral nasal mask who uses clinically is mostly single chamber structure, can not adjust respectively the air output of mouth, nose, though can effectively improve the patient and ventilate under the good condition of patient's cooperation, nevertheless because respiratory failure is early, patient respiratory rate is fast, and most patients can't tolerate the malleation and ventilate, often open one's mouth and breathe to increase the risk of patient's abdominal distension, and the risk of this type of patient's aspiration pneumonia also increases thereupon.
(3) Some nose masks or mouth-nose masks have no independent airflow adjusting device, and can only adjust and change the parameters of a connected respirator in clinical use, while the parameters of a pager are complex, have higher technical requirements on a regulator, and need to be communicated and adjusted with a patient repeatedly. In some critical patients, especially those who combine with disturbance of consciousness but refuse to assist ventilation with invasive ventilator, cannot communicate effectively, are difficult to assist ventilation with noninvasive ventilator, often breathe with mouth opening, and the existing mouth-nose mask is easier to increase the risk of abdominal distension and aspiration pneumonia.
(4) The existing ventilation mask brings abdominal distension to patients when positive pressure ventilation is carried out, and the ventilation condition of the mouth or the nose can be independently adjusted because the existing ventilation mask does not exist.

This requires that the positive pressure air pass through the mask as far as possible through the nasal passages into the respiratory passages, and not through the oral passages into the stomach, causing flatulence. However, most patients can breathe by mouth opening under the stimulation of positive pressure gas in the specific implementation process so as to relieve the uncomfortable feeling of compression, and because the mouth-nose separated mask needs to be designed, the patients are sequentially and gradually induced to adapt to the state of non-invasive positive pressure ventilation, and finally adapt to nasal ventilation so as to improve the success rate.
The significance of solving the problems and the defects is as follows: through designing a mouth separable face guard of nose, can improve clinically because of using not creating the abdominal distension that positive pressure ventilation brought for some patients of creating to reduce the risk of aspiration pneumonia, and through adjusting the entry airflow and induce the patient to adapt to not creating the positive pressure ventilation state gradually, thereby increase the treatment success rate.
