负压牵引呼吸方法及其装置 Traction breathing method and apparatus underpressure

技术领域 FIELD

本发明涉及呼吸医疗技术,特别涉及一种负压牵引呼吸方法及其装置。 The present invention relates to a respiratory medical technology, particularly to a method and apparatus for negative pressure respiratory traction.

背景技术 Background technique

人体要维持正常的生命活动,就必须不断地从外界摄入氧气,同时从体内呼出大量的二氧化碳,以维持生命的新陈代谢。 The body to maintain normal life activities, we must continue to intake of oxygen from the outside world, while the amount of carbon dioxide exhaled from the body to maintain metabolism of life. 正常人体平静的呼吸是通过鼻咽呼吸通道吸入新鲜的氧气和呼出代谢后的二氧化碳;一般的呼吸过程包括外呼吸、气体在血液中运输和内呼吸三个相互关联的环节,外呼吸是指血液与外界空气在肺部实现的气体交换过程,包括通气和换气二个方面,所述通气是指肺泡与外界气体的交换过程,所述换气是指肺泡与血液之间气体的交换过程;气体在血液中的运输是指肺毛细血管与组织毛细血管之间进行气体运输过程;所述内呼吸是指血液通过组织液与组织细胞之间的气体交换过程。 Quiet breathing normal human fresh oxygen is inhaled through the respiratory passage and exhaled carbon dioxide nasopharynx after metabolism; generally includes an outer breathing during respiration, the respiratory gas transport and three links interconnected in the blood, blood refers to the external respiration with the outside air in the lungs to achieve a gas exchange process, including ventilation and gas exchange two aspects, the alveolar ventilation is the exchange process with the outside air, the ventilation means exchange between alveolar gas and blood; gas transport in the blood is meant the process gas transport between the capillary and the pulmonary capillary tissue; refers to the blood through the respiratory gas exchange between the tissue and the tissue fluid. 通过对肺通气和气体交换的分析与研究发现:如果超量呼出体内的二氧化碳,刺激呼吸中枢神经,加强呼吸深度,那么可以有效地提高肺泡通气量,随着肺泡通气量的增大,适当调整肺内的氧分压和二氧化碳分压,可以提高肺泡与肺毛细血管的气体交换,使机体获得充分的氧气,对促进肺功能以及保持机体高氧分的代谢以及对改善和治疗呼吸系统引发的各种疾病都有明显的益处。 Through the analysis of gas exchange and pulmonary ventilation studies and found that: if excessive carbon dioxide exhaled in vivo, stimulation of the central nervous respiratory enhance the depth of breathing, it can effectively increase the amount of alveolar ventilation, increases as the amount of alveolar ventilation, appropriate adjustments lung partial pressure of oxygen and carbon dioxide, can improve the gas-exchange alveolar pulmonary capillary, sufficient oxygen so that the body, to promote lung function and to maintain the body's metabolism and high oxygen partial improvement and treatment of the respiratory system caused by various diseases have significant benefits.

目前,在呼吸内科对呼吸病患者所使用的通气机或呼吸机是一种由外界介入人体,并在体外产生呼吸功能的医疗设备,它们基本上可分为常频通气机(10~60次/分钟)和高频通气机(大于60次/分钟)。 Currently, the ventilator or respiratory ventilator breathing patients for medical use is an intervention from outside the human body, the medical device and generates respiratory function in vitro, they can be divided substantially normal frequency ventilator (10 ~ 60 / min) and high frequency ventilator (greater than 60 times / min). 这类呼吸设备通常用于严重的呼吸衰竭或呼吸窘迫综合症的高危患者,其特点是在外体制定呼吸频率,设定合理的气体交换指标(PaO2、P(Aa)O2、PaCO2)以及循环指标,并对心输出量、心脏指数等循环指标进行在线监测,从而对昏迷、呼吸不规则、迷失自主呼吸功能的高危患者进行有效机械通气;这类呼吸设备的作用原理是使人体产生被动呼吸,与前述人体自主的主动呼吸有明显区别。 Such devices are often used in high-risk patients breathing severe respiratory failure or respiratory distress syndrome, which is characterized by the development of the outer body respiratory rate, set a reasonable gas exchange index (PaO2, P (Aa) O2, PaCO2) and a cyclic indicators , and cardiac output, cardiac index and other indicators line monitoring cycle, thus coma, irregular breathing, lost in high-risk patients with spontaneous breathing function for effective mechanical ventilation; respiratory equipment such action principle is to make the body produce passive breathing, a significant difference to the human body with active breathing autonomy.

在专利号为98101665.0的中国发明专利中公开了一种“在哺乳动物(包含人类)的口腔建立真空/负压的方法和装置”,其主要特点是机体在用鼻通道进行呼吸时,在使用者的口腔内建立并保持真空,利用这个真空增进使用者的淋巴液流动,从而达到治疗的目的;这种与法及装置并不改变机体自体呼吸的习惯,仅在口腔中产生真空/负压并阻止经口腔呼吸,对口腔中的淋巴液起作用,并不能刺激呼吸中枢神经,加强呼吸深度,超量呼出体内的二氧化碳,因而不能提高呼吸质量,使机体获得充分的氧气。 Disclosed in Chinese Patent No. 98101665.0 patent of a "create a vacuum / negative pressure in the apparatus and method of oral mammalian (including human)", in its main features is the body's breathing when nasal passages, using establishing and maintaining the oral cavity by vacuum, using the vacuum lymph flow enhancing user to achieve the purpose of treatment; this does not change the method and the apparatus body autologous breathing habits, only create a vacuum / negative pressure in the mouth and preventing breathing through the mouth, lymph fluid acting on the oral cavity, respiratory and central nervous not stimulate and strengthen the depth of breathing, the body of excess exhaled carbon dioxide, and therefore can not improve the quality of breathing, so that the body sufficient oxygen.
