Description

集成消毒功能的麻醉呼吸设备Anesthetic breathing apparatus with integrated disinfection function
【技术领域】[Technical Field]

【背景技术】【Background technique】
麻醉呼吸设备除了外接的管道可以一次性地使用后废弃,机器本身的内部呼吸回路一般需重复多次使用,未经内部消毒处理即反复使用的麻醉呼吸设备容易造成微生物污染。由麻醉呼吸设备引起的感染,最多见的为呼吸道细菌感染,特别是结核分枝杆菌、非典型分枝杆菌所引起的感染,近来亦发现有HBV(hepadnavividae,乙型肝炎病毒)、HCV(hepatitis C virus,丙型肝炎病毒抗体)感染。如果病菌存留在这些医疗设备内部,那么由此引发的医源性感染将带来无法估量的危害和损失。所以,对病人用过的麻醉呼吸设备进行有效的消毒灭菌很有必要。Anesthesia breathing equipment can be discarded after being used once, except for the external piping. The internal breathing circuit of the machine itself is usually used repeatedly. The anesthetic breathing equipment that is used repeatedly without internal disinfection is likely to cause microbial contamination. The most common infections caused by anesthesia breathing equipment are respiratory bacterial infections, especially those caused by Mycobacterium tuberculosis and atypical mycobacteria. Recently, HBV (hepadnavividae, hepatitis B virus) and HCV (hepatitis) have also been found. C Virus, hepatitis C virus antibody) infection. If the germ remains in these medical devices, the resulting iatrogenic infection will cause immeasurable harm and loss. Therefore, it is necessary to effectively disinfect and disinfect the anesthesia breathing equipment used by the patient.
目前通常采用的消毒方式是,将机器的呼吸回路部分拆下,进行高温高压灭菌或进行戊二醛、环氧乙烷等消毒。但由于需要反复拆装,操作麻烦,且因操作不当还会造成机器的损伤。另外,麻醉呼吸设备通常只能在使用一段时间后进行一次消毒,并且很多情况下一台麻醉机一天会安排多例手术,而很难做到每病例逐一消毒,使其长期处于无菌状态。目前国际上对此感染途径的控制也有专门的研究,主要为呼吸过滤器的研制和推广使用。在呼吸过滤器中使用了某种复合的滤膜,可以过滤细菌和病毒。但从本质上讲,它是一种被动的隔离措施,各种细菌和病毒都还存活,附着于滤膜和仪器上,还存在交叉感染的危险。At present, the disinfection method usually adopted is to remove the breathing circuit part of the machine, perform high temperature autoclaving or sterilize glutaraldehyde or ethylene oxide. However, due to the need for repeated disassembly and assembly, the operation is troublesome, and the machine may be damaged due to improper operation. In addition, anesthesia breathing equipment can usually be disinfected only once after a period of use, and in many cases the next anesthesia machine will arrange multiple operations a day, and it is difficult to disinfect each case one by one to make it sterile for a long time. At present, there are special researches on the control of this infection route in the world, mainly for the development and promotion of respiratory filters. A complex membrane is used in the respiratory filter to filter bacteria and viruses. But in essence, it is a passive isolation measure, a variety of bacteria and viruses are still alive, attached to the filter membrane and instruments, there is a risk of cross-infection.

In the inhalation phase, the folding capsule 419 presses the circulating gas in the circuit together with the sterilizing substance injected with the fresh gas into the manual bag 430; in the exhalation phase, the manual bag 430 presses the circulating gas mixed with the sterilizing and sterilizing substance into the folding The bladder 419, excess gas is expelled from the safety valve 415 and the exhalation valve 417, thereby completing a breathing cycle. Repeatedly, the sterilizing and sterilizing substances are evenly distributed to various positions in the circuit by rinsing, spreading, spreading, or utilizing the breathing action of the anesthetic breathing apparatus 100 itself. In addition, the effective disinfection and sterilization of the manual branch and the machine-controlled branch can be achieved by maintaining a stable concentration for a period of time to meet the requirements of sterilization and sterilization. It will be appreciated that in other embodiments, the manual branch and the machined branch may be separately sterilized separately.
如图4-6所示,在进行消毒操作时,亦可将手动囊430与管道11省略,而将麻醉呼吸设备100中支路出口进行封闭,使消毒灭菌物质能够在回路中流动或传播而不泄露到外界即可。例如,可直接封闭吸气管路23、呼气管路13以及手动支臂431的出口(如图4);将吸气管路23和呼气管路13用波纹管连接(如图5)或将呼气管路13堵上用波纹管连接吸气管路23和手动支臂431(如图6)。As shown in FIG. 4-6, when the sterilization operation is performed, the manual capsule 430 and the pipe 11 can be omitted, and the branch outlet of the anesthetic breathing apparatus 100 can be closed, so that the disinfecting and disinfecting substance can flow or spread in the circuit. Not leaking to the outside world. For example, the inspiratory line 23, the expiratory line 13 and the outlet of the manual arm 431 can be directly closed (as shown in Fig. 4); the inspiratory line 23 and the expiratory line 13 are connected by a bellows (Fig. 5). Or plug the expiratory line 13 with a bellows to connect the inspiratory line 23 and the manual arm 431 (see Figure 6).
采用上述方式时,吸气阶段,折叠囊419将回路中的循环气体和随新鲜气体注入的消毒灭菌物质压入并经切换装置50扩散至呼气装置10与吸气装置20内;呼气阶段,混合有消毒灭菌物质的循环气体又由呼气装置10与吸气装置20被重新压入至折叠囊419内。如此反复,经过一段时间冲洗、扩散、传播、或者利用麻醉呼吸设备100自身的呼吸动作将消毒灭菌物质均匀分布到回路中的各个位置。另外,通过保持一段时间满足消毒和灭菌要求的稳定浓度,即可实现手动支路和机控支路的有效消毒灭菌。In the above manner, in the inhalation phase, the folding capsule 419 presses the circulating gas in the circuit and the sterilization and sterilization substance injected with the fresh gas into the exhalation device 10 and the inhalation device 20 through the switching device 50; At the stage, the circulating gas mixed with the sterilizing and sterilizing substance is again reintroduced into the folding capsule 419 by the exhalation device 10 and the suction device 20. Repeatedly, the sterilizing and sterilizing substances are evenly distributed to various positions in the circuit by rinsing, spreading, spreading, or utilizing the breathing action of the anesthetic breathing apparatus 100 itself. In addition, the effective disinfection and sterilization of the manual branch and the machine-controlled branch can be achieved by maintaining a stable concentration for a period of time to meet the requirements of sterilization and sterilization.
上述麻醉呼吸设备100集成有消毒灭菌装置60,消毒灭菌物质在麻醉呼吸设备100的回路中流动或利用麻醉呼吸设备100自身的气体循环,实现回路内各个位置的自动消毒,而无需拆卸回路。同时,在进行消毒操作时,可以同时进行手控支路与机控支路的消毒,也可以分开进行,操作简单且方便。The anesthetic breathing apparatus 100 described above is integrated with a sterilization and sterilization device 60. The sterilization and sterilization substance flows in the circuit of the anesthetic breathing apparatus 100 or utilizes the gas circulation of the anesthetic breathing apparatus 100 itself to realize automatic disinfection of various positions in the circuit without disassembling the circuit. . At the same time, during the disinfection operation, the manual control branch and the machine control branch can be disinfected at the same time, or separately, and the operation is simple and convenient.
