Description
Technical Field
The utility model relates to a medical or medical breathing mask, in particular to a noninvasive PEEP buffering positive pressure ventilation mask.
Background
The non-invasive positive pressure ventilation (NPPV) is an auxiliary positive pressure mechanical ventilation that is connected to a patient in a non-invasive manner, such as a nasal mask, an oronasal mask, or a full face mask. NPPV has become an important technical means for various types of acute respiratory failure treatment and chronic respiratory failure rehabilitation. However, carbon dioxide (CO) is likely to be generated due to the significant dead space effect existing in the existing NPPV mask2) The gas breathes repeatedly. When NPPV is used for treating chronic obstructive pulmonary disease and the like with CO2Significant CO is often caused by the presence of large dead space gas volume in the mask when patients are retained2Repeated breaths and higher end-tidal carbon dioxide partial pressure (PetCO)2) Possibly further aggravating the patient's CO2Retention levels, thereby affecting the effectiveness of noninvasive positive airway pressure therapy. Meanwhile, the conventional NPPV mask also faces the problem that independent adjustable end-expiratory pressure (PEEP) regulation cannot be realized, the problem that the exhaled gas of the patient cannot be filtered, and the problem that the patient feels uncomfortable after directly facing continuous airflow for a long time due to no buffer device. Because of the importance of Positive End Expiratory Pressure (PEEP) to patient treatment, there is a clinical need for a noninvasive positive airway pressure mask that achieves Positive End Expiratory Pressure (PEEP) using only bedside oxygen without the use of a ventilator.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a noninvasive PEEP (positive expiratory pressure) buffering positive airway pressure mask, which mainly solves the problems that the existing NPPV mask cannot realize independent positive end expiratory pressure regulation, cannot filter gas exhaled by a patient and causes discomfort of the patient due to the fact that the patient directly faces continuous airflow for a long time without a buffering device.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a noninvasive PEEP buffering positive pressure ventilation mask comprises a mask body, wherein the mask body is connected with one end of a breathing tube, and the other end of the breathing tube is respectively connected with an O2Joint and end-tidal CO2The joints form a three-way structure; the method is characterized in that: the O is2A PEEP regulating valve and a one-way valve are arranged between the joint and the other end of the breathing tube.
