Problems solved by technology

However, due to the softness and elasticity of the folding pouch material, it is difficult to precisely control when the ventilation volume is small, and there is a small positive end-expiratory pressure in the safety valve, which has a serious impact on the ventilation of newborns, which may lead to insufficient ventilation.

Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

Disclosed is an anesthesia machine respiratory system (10), comprising a driving gas isolation device (100), a driving gas control system (200) and a circulatory-respiratory system (300). Both the driving gas control system (200) and the circulatory-respiratory system (300) are in communication with the driving gas isolation device (100). The driving gas isolation device (100) comprises a device main body (110). At least two airways (130) arranged in parallel are provided in the device main body (110). The airways (130) are elongated structures. The driving gas isolation device (100) achieves non-physical isolation between the driving gas and a mixed gas carrying a large amount of narcotic drugs by the elongated and parallel airways (130), wherein no elastic component such as a folded capsule is used, which makes the driving gas isolation device (100) control the pressure and flow more accurately. In addition, also provided is an anesthesia machine which uses the anesthesia machine respiratory system (10).

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an anesthesia machine and its breathing system. Background technique [0002] The breathing system of the anesthesia machine is divided into a non-rebreathing system and a rebreathing system. Anesthesia machines with rebreathing systems are the most widely used. Different from the non-rebreathing system, in the anesthesia machine of the rebreathing system, the gas exhaled by the patient is reused. Specifically, a bellows structure is usually used to isolate the driving gas from the patient's exhaled gas, so as to reduce the loss of anesthetic drugs exhaled by the patient. When exhaling, the fresh gas and the gas exhaled by the patient enter the folding bag in the bellows together, and when inhaling, the driving gas enters the bellows, and the gas in the driving bag enters the patient's lungs again. [0003] In traditional anesthesia machines, most of the driving gas isolation ...
