Description
Translated fromChinese技术领域technical field
本发明涉及肺功能测量的阻断(occlusion)技术领域，更具体地本发明涉及一种肺功能手持测量阻断装置、测量装置和系统。The present invention relates to the technical field of occlusion of pulmonary function measurement, and more particularly, the present invention relates to an occlusion device, measurement device and system for hand-held pulmonary function measurement.
背景技术Background technique
为了测量肺功能，在过去已经开发了各种技术，包括单阻断技术(SOT)和阻断技术(Rint)。这些技术利用气流路径中的暂时阻塞(阻断)来短时间内中断正常呼吸周期。在此阻断过程中，执行特定变量的测量，如压力和流量。然后，可以通过流量和压力计算气道阻力。更具体地，单阻断技术(SOT)利用新生儿直到12个月的幼儿的肺牵张反射(Hering-Breuer reflex)。因此，此项技术可用于小于1岁的幼儿。Rint技术适用于年龄范围从1岁到100岁的人。此项技术计算气道的内部阻力，并可用于不能产生峰值流量和遵守护理者指示的人。肺活量测定技术适用于年龄范围约为5-100岁的人。此项技术测量在强制的深呼气和吸气期间的峰值流量和体积。对于SOT/Rint测量，三个值是计算所要求的呼吸参数所必要的：空气流量、容量和压力。对于肺活量测定变量，流量和容量值是用于计算呼吸参数所必要的。使用超声换能器飞行时间原理测量流量，接收超声波的换能器之间的时间差是换能器之间的气流传播的速度，通过整合流量随时间计算气体容量，换能器由发送器和接收器组成。在阻断期间，气流被阻塞，并取决于在阻断呼吸周期期间的时刻，压力在流管中聚集。该压力应尽可能地接近口腔来测量，计算呼吸参数的方法已经由欧洲呼吸协会和美国胸外科协会公布；现在，测量在0-1岁之间的婴儿的还做不到，因为它不利用婴儿的肺牵张反射并且这是由唤醒沉睡婴儿而引起的嘈杂测量。阻断是由“蝶阀”实现。针对较低压力，这种结构是不持久的。To measure lung function, various techniques have been developed in the past, including the single occlusion technique (SOT) and the occlusion technique (Rint). These techniques utilize temporary blockages (blocks) in the airflow path to interrupt the normal breathing cycle for short periods of time. During this blocking process, measurements of specific variables, such as pressure and flow, are performed. Airway resistance can then be calculated from flow and pressure. More specifically, the single occlusion technique (SOT) utilizes the Hering-Breuer reflex of young children from neonates up to 12 months of age. Therefore, this technology can be used for young children less than 1 year old. Rint technology is suitable for people ranging from 1 to 100 years old. This technique calculates the internal resistance of the airway and can be used for people who cannot produce peak flow and follow caregiver instructions. The spirometry technique is suitable for people in the age range of approximately 5-100 years. This technique measures peak flow and volume during forced deep expiration and inspiration. For SOT/Rint measurements, three values are necessary to calculate the required breathing parameters: air flow, volume and pressure. For spirometry variables, flow and volume values are necessary for calculating respiratory parameters. The flow is measured using the ultrasonic transducer time-of-flight principle, the time difference between the transducers receiving the ultrasonic wave is the speed of the air flow between the transducers, the gas volume is calculated by integrating the flow over time, the transducer is composed of the transmitter and the receiver device composition. During occlusion, the airflow is blocked and depending on the moment during the occluded breathing cycle, pressure builds up in the flow tube. This pressure should be measured as close to the mouth as possible, and methods for calculating respiratory parameters have been published by the European Respiratory Society and the American Society of Thoracic Surgeons; at present, measurements in infants between 0-1 years of age are not possible because it does not utilize Lung stretch reflex in infants and this is a noisy measurement caused by waking a sleeping infant. Blocking is achieved by a "butterfly valve". For lower pressures, this structure is not durable.
现有设备的缺点包括不能测不能自主呼吸的成年病人，不能测2岁以下年龄段能够自主呼吸的病人；现有的SOT和Rint技术都是都是建立在昂贵的基础系统上的选项模块，而且这些系统使用除超声波之外的其他方法来测量流量；各种竞争产品都是昂贵的台式产品，没有用于能够评估婴儿、儿童和无法进行肺活量测定的老年人的便携式肺功能设备；现有的手持肺功能呼吸仪，采用电机驱动致动器通过抵靠气流管的壁部实现气流阻断，由于电机通过机械臂驱动，该方法的阻断时间控制精度不高。The shortcomings of the existing equipment include that it cannot measure adult patients who cannot breathe spontaneously, and cannot measure patients under 2 years old who can breathe spontaneously; the existing SOT and Rint technologies are both optional modules based on expensive basic systems. And these systems use methods other than ultrasound to measure flow; the various competing products are expensive benchtop products without portable pulmonary function equipment for evaluating infants, children, and older adults who cannot perform spirometry; existing The hand-held pulmonary function respirator adopts a motor-driven actuator to achieve airflow blocking by abutting against the wall of the airflow tube. Since the motor is driven by a mechanical arm, the blocking time control accuracy of this method is not high.
