技术领域Technical field
本发明涉及胸腔内压测量技术领域，尤其是涉及一种持续胸腔内压监测的多功能胸腔球囊导管装置。The invention relates to the technical field of intrathoracic pressure measurement, and in particular to a multifunctional thoracic balloon catheter device for continuous intrathoracic pressure monitoring.
背景技术Background technique
胸腔内压是指胸膜腔内的压力(Ppl)，测量表明胸膜腔内压比大气压低，为负压。平静呼气末约为-0.665—-0.399kPa(-5—-3mmHg)，吸气末约为-1.33—-0.665kPa(-10—-5mmHg)。治疗严重急性呼吸窘迫综合征(ARDS)时，ICU医生经常会通过计算吸气末跨肺压(平台压-胸腔内压)滴定潮气量、呼气末跨肺压(peep-食道压)滴定peep进行肺保护通气。因此监测胸腔内压对指导呼吸机参数的设定并预测预后至关重要。Intrathoracic pressure refers to the pressure in the pleural cavity (Ppl). Measurement shows that the pressure in the pleural cavity is lower than atmospheric pressure and is negative pressure. Calm end of expiration is about -0.665--0.399kPa (-5--3mmHg), and end-of-inspiration is about -1.33--0.665kPa (-10--5mmHg). When treating severe acute respiratory distress syndrome (ARDS), ICU doctors often titrate tidal volume by calculating end-inspiratory transpulmonary pressure (platform pressure - intrathoracic pressure) and end-expiratory transpulmonary pressure (peep - esophageal pressure). Perform lung protective ventilation. Therefore, monitoring intrathoracic pressure is crucial to guide the setting of ventilator parameters and predict prognosis.
目前可用两种方法测定胸腔内压。一种是直接法，将与检压计相连接的注射针头斜刺入胸膜腔内，检压计的液柱即可直接指示胸膜腔内的压力。直接法的缺点是有刺破胸膜脏层和肺的危险。另一种方法是间接法，让受试者吞下带有薄壁气囊的导管至下胸部的食管，由测量呼吸过程中食管内压变化来间接地指示胸膜腔内压变化。这是因为食管在胸内介于肺和胸壁之间，食管壁薄而软，在呼吸过程中两者的变化值基本一致，故可以测食管内压力的变化以间接反映胸膜腔内压的变化。但是，食道压不等于胸腔内压，一般情况下食道压大于胸腔内压，应用时除了需要考虑生理和病理状态的影响外，在操作时还需要进行气囊的定位和充气容积量的评估。且两种方法无法实现胸腔闭式引流。Two methods are currently available to measure intrathoracic pressure. One is the direct method, in which the injection needle connected to the manometer is inserted obliquely into the pleural cavity, and the liquid column of the manometer can directly indicate the pressure in the pleural cavity. The disadvantage of the direct method is the risk of puncturing the visceral pleura and lungs. Another method is the indirect method, which allows subjects to swallow a catheter with a thin-walled balloon to the esophagus in the lower chest, and indirectly indicates changes in pleural pressure by measuring changes in esophageal pressure during breathing. This is because the esophagus is between the lungs and the chest wall in the chest. The esophageal wall is thin and soft. The changes in the two during breathing are basically the same. Therefore, the changes in pressure in the esophagus can be measured to indirectly reflect the pressure in the pleural cavity. Variety. However, the esophageal pressure is not equal to the intrathoracic pressure. Generally, the esophageal pressure is greater than the intrathoracic pressure. In addition to considering the influence of physiological and pathological conditions, the positioning of the air bag and the assessment of the inflation volume are also required during operation. And the two methods cannot achieve closed chest drainage.
专利CN107613865A提供一种胸腔内压计算装置以及胸腔内压计算方法，该专利通过仿真来推导得出胸内压与口腔内压之间的关系，基于该关系，通过测量口腔内压来得到相应的胸内压。该方案的优点是无创，对被测量者的损害小且不会产生不适，缺点是，通过仿真得到的胸内压和口腔内压之间的关系不准确，且也不能实现胸腔闭式引流。Patent CN107613865A provides an intrathoracic pressure calculation device and an intrathoracic pressure calculation method. This patent uses simulation to derive the relationship between intrathoracic pressure and intraoral pressure. Based on this relationship, the corresponding intrathoracic pressure is obtained by measuring the intraoral pressure. Intrathoracic pressure. The advantage of this solution is that it is non-invasive, causes little damage to the person being measured, and does not cause discomfort. The disadvantage is that the relationship between the intrathoracic pressure and the intraoral pressure obtained through simulation is inaccurate, and closed chest drainage cannot be achieved.
