Description
技术领域technical field
本发明涉及气体净化技术领域，具体涉及一次性手术烟雾净化器。The invention relates to the technical field of gas purification, in particular to a disposable surgical smoke purifier.
背景技术Background technique
目前手术烟雾的防护方法有四种，各有一定的不足。(1)选择合适的口罩：标准的手术口罩并不能为佩戴者在手术烟雾中提供有效的防护，它通常只能滤除5μm以上的颗粒，而手术烟雾中77％的颗粒直径小于1.1μm。(2)负压吸引系统：要将吸引器放于烟雾源2.54～5.08cm的范围内才能有效吸除烟雾，如果超过这一范围，效果将会减半。而标准的吸引器为了防止堵塞没有配置高性能的过滤器，被吸走的烟雾只进入了吸引瓶内，负压停止时烟雾有弥散出来的危险。(3)腔镜手术的排烟系统：在腔镜手术的过程中或手术完成后，用高含氧量的空气对腹腔进行间歇或持续性换气，可降低CO浓度并避免切口的烟雾泄露；在手术过程中，负压吸除烟雾，防止烟雾的积累，同时在阀门上连接过滤器。(4)手术烟雾净化装置：目前的手术烟雾净化装置主要通过过滤和吸附来处理手术烟雾，具有一定的净化效率，但是普遍体积大，使用不方便，且无法确保病人用到的净化装置做到一用一清洗消毒，存在交叉感染的风险。At present, there are four kinds of protective methods for surgical fumes, each of which has certain deficiencies. (1) Choose a suitable mask: Standard surgical masks cannot provide effective protection for the wearer in surgical smoke. It usually only filters out particles above 5 μm, while 77% of the particles in surgical smoke are smaller than 1.1 μm in diameter. (2) Negative pressure suction system: The suction device must be placed within the range of 2.54-5.08cm from the smoke source to effectively suck the smoke. If it exceeds this range, the effect will be halved. The standard suction device is not equipped with a high-performance filter in order to prevent clogging, and the sucked smoke only enters the suction bottle. When the negative pressure stops, the smoke may disperse. (3) Smoke exhaust system for laparoscopic surgery: during or after laparoscopic surgery, the abdominal cavity is ventilated intermittently or continuously with air with high oxygen content, which can reduce the CO concentration and avoid smoke leakage from the incision ;During the operation, smoke is sucked by negative pressure to prevent the accumulation of smoke, and a filter is connected to the valve at the same time. (4) Surgical smoke purification device: The current surgical smoke purification device mainly processes surgical smoke through filtration and adsorption. One use one cleaning and disinfection, there is a risk of cross-infection.

Escherichia coli was selected as the indicator bacteria, and the concentration was 10 6 CFU/mL. When the surgical smoke flow rate was 0.5L/min, 1.0L/min, 1.5L/min, and 2.0L/min, the bacterial removal rates were 97.5%, 96.9%, respectively. %, 95.9%, 95.1%; when the concentration of carbon monoxide is in the range of 100-1000mg/L, the efficiency of the disposable surgical smoke purifier to remove carbon monoxide is higher than 90%; when the flow of surgical smoke is 1.0L/min, the concentration of toluene is At 5ppm, the removal rate of toluene by the gas purification device is 86.2%.
综上所述，本发明具有以下有益技术效果：第一，可以有效去除气体中的有机污染气体、一氧化碳、二氧化碳、病毒及细胞碎片，给患者与医疗人员提供一个干净、安全的手术环境并减少了废气对环境的污染；第二，体积小，使用简便；第三，可以保持患者一用一更换，切断了疾病传播途径，有效地预防和控制院内交叉感染。In summary, the present invention has the following beneficial technical effects: First, it can effectively remove organic pollutant gases, carbon monoxide, carbon dioxide, viruses and cell fragments in the gas, provide patients and medical personnel with a clean and safe operating environment and reduce Second, it is small in size and easy to use; third, it can keep patients using and replacing each other, cut off the disease transmission route, and effectively prevent and control nosocomial cross-infection.
上述实施例为本发明较佳的实施方式，但本发明的实施方式并不受上述实施例的限制，其他的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本发明的保护范围之内。The above-mentioned embodiment is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above-mentioned embodiment, and any other changes, modifications, substitutions, combinations, Simplifications should be equivalent replacement methods, and all are included in the protection scope of the present invention.
