Description

麻醉机、呼吸机容量保障压力限制通气方法 Anesthesia machine, ventilator capacity of the ventilation pressure limit protection methods

技术领域 FIELD

[0001] 本发明涉及一种麻醉机、呼吸通气保障方法,用于提升麻醉机和呼吸机容量控制下因R值过大,C值过小时Ppeak过大引起病人诱发气压伤的问题,提升容量通气下压力限制的安全性,属于医疗设备制造技术领域。 [0001] The present invention relates to an anesthetic machine, to protect respiratory ventilation method for lifting the R value is too large due to, C Ppeak value had problems caused by excessive hours induced barotrauma patient under anesthesia machine and ventilator capacity control, the capacity to enhance safety vent at a pressure of limitation, medical devices belonging to the technical field of manufacturing.

背景技术 Background technique

[0002] 目前在麻醉机和呼吸机控制多采用容量控制或压力控制。 [0002] anesthesia machine and ventilator use more control volume control or pressure control. 通常情况下此两种控制方法只能对应特殊的患者群: Normally this only two control methods corresponding to particular groups of patients:

[0003] 容量控制,其优点是可根据医生设定潮气量,定时为病人提供指定容量的通气,通气精度高,每次供应的潮气量几乎一致。 [0003] volume control, the advantage of tidal volume may be set according to the doctor, the timing specified capacity to provide ventilation for the patient, high precision ventilation, tidal volume supplied per almost identical. 缺点是此控制方法通常只能应用于肺部无病变,或病变不厉害的环境;对于肺部病变比较厉害、婴幼儿,R值过大、C值过小时由于气道气阻过大,容量通气时流速过快会引起峰值压力过高,导致气压伤。 The disadvantage is that this method generally only be applied to a control without pulmonary disease, or disorder not severe environment; for more severe lung disease, infant, R value is too large, C value is excessively small due to the air resistance is too large airways, capacity peak flow rate is too fast can cause excessive pressure during ventilation, causing barotrauma.

[0004] 压力控制,其优点是可根据医生设定压力,定时为病人提供指定压力的通气,每次供应的压力值几乎一致,可应用于肺部有病变的环境,以及婴幼儿,适应患者群广。 [0004] pressure control, the advantage of a doctor according to the set pressure, the timing specified pressure to provide ventilation for the patient, the supply pressure is almost the same value every time, can be applied to environmental lung disease, and infants, adapted to the patient group wide. 缺点是压力控制方法通气无法对容量进行实时保障,只会按照预设压力进行通气,每次供应的潮气量随着患者R、C值的变化而变化,无法精确控制潮气量。 The disadvantage is that the pressure control ventilation method can not guarantee real-time capacity, it will only be ventilated in accordance with a preset pressure, the amount of each tidal change in the supply of patients with R, C values ​​change, can not be accurately controlled tidal volume.

[0005] 随着通气技术的发展,又出现了容量保障压力限制方法,此种方法可实现容量和压力双重保障,使得适应患者群广,并且可以精确控制潮气量。 [0005] With the development of technology, ventilation, there was pressure to limit the capacity of guarantee method, this method can achieve double protection capacity and pressure, making the patient population to adapt to a wide, and can be precisely controlled tidal volume. 但此种方法也有一定缺陷, 其采用按定值调节压力的方法对容量进行保障控制,每次调节都采用士5cmH20的定值来实现,导致容量偏差比较大,而且要达到预设潮气量需要5到10个周期或者更长时间才能达到,调节速度过慢。 However, this method has certain defects, which method by adjusting the pressure value for controlling the capacity for protection, each adjustment value are used to achieve 5cmH20 persons, resulting in relatively large capacitance variation, and the need to reach a preset tidal volume 5-10 cycles or longer to reach adjusted too slow.

[0006] 上述方法所存在的缺陷都会直接影响到麻醉机和呼吸机的控制性能和控制响应速度,导致麻醉机和呼吸机舒适性下降。 [0006] The method of the above-described defects are present directly affects the control performance and control response speed of the anesthesia machine and ventilator, anesthesia machine and ventilator resulting in reduction in comfort.
