背景技术：Background technique:
在医疗领域内，输氧不但是抢救危重病人的一种重要医疗措施，也是最常见的临床治疗手段，氧气的补给可以改善人体的生理、生化内环境、促进代谢过程的良性循环，从而达到治疗疾病、缓解症状、促进康复和预防病变、增进健康的目的，是辅助治疗多种疾病的重要方法之一，因此，氧气在医疗领域尤其是在危重病人和意外伤害者的急救方面起着重要的作用，输氧成为医疗机构的必备条件之一。In the medical field, oxygen infusion is not only an important medical measure to rescue critically ill patients, but also the most common clinical treatment method. Oxygen supply can improve the physiological and biochemical internal environment of the human body, and promote a virtuous cycle of metabolic processes, so as to achieve the treatment of diseases The purpose of relieving symptoms, promoting recovery and preventing disease, and improving health is one of the important methods for auxiliary treatment of many diseases. Therefore, oxygen plays an important role in the medical field, especially in the first aid of critically ill patients and accidental injuries. , Oxygen delivery has become one of the necessary conditions for medical institutions.
集中供氧又称中心供氧，是国际上广泛使用的现代化供氧方式，我国自1983年研制出第一套集中供氧系统以来，已经在医院中得到广泛的推广应用，目前稍具规模的医院都已采用集中供氧系统，医院集中供氧系统由氧源、不锈钢输氧管道、减压、控制阀和设备终端几部分组成，大多医院以液氧作为氧源，以液氧作为氧气源的供氧系统，主要由液氧贮罐、汽化器、减压装置及报警装置等组成，液氧由气体生产公司用液氧运输罐车注入到集中供氧系统的液氧贮罐，液氧在生产、液化、精馏、危险杂质排除的工序后，是不含水分、无灰尘、无油、无臭、无味液体，但在吸氧治疗中，由于医院集中供氧系统中氧气源、供氧管道及病房终端长时间、不间断的使用，会滋生一种难以忍受的异味，特别是对气味敏感的患者，更是拒绝吸氧治疗。Centralized oxygen supply, also known as central oxygen supply, is a modern oxygen supply method widely used in the world. Since the first centralized oxygen supply system was developed in China in 1983, it has been widely promoted and applied in hospitals. Hospitals have adopted a centralized oxygen supply system. The hospital’s centralized oxygen supply system consists of oxygen sources, stainless steel oxygen pipelines, decompression, control valves and equipment terminals. Most hospitals use liquid oxygen as the oxygen source, and liquid oxygen as the oxygen source. The oxygen supply system is mainly composed of a liquid oxygen storage tank, a vaporizer, a decompression device, and an alarm device. The liquid oxygen is injected into the liquid oxygen storage tank of the centralized oxygen supply system by the gas production company using a liquid oxygen transport tanker. After the process of liquefaction, rectification, and removal of dangerous impurities, it is a liquid without moisture, dust, oil, odor, and taste. However, during oxygen inhalation therapy, due to the oxygen source, oxygen supply pipeline and Long-term and uninterrupted use of the terminal in the ward will produce an unbearable odor, especially for patients who are sensitive to odors and refuse oxygen therapy.
人工制备的医用氧气极其干燥，如果直接吸入医用氧气，会导致患者呼吸道干燥不适，因此，其输氧设备中的氧气湿化装置成为患者吸氧过程中的必须环节，是医院必不可少的医疗设置之一，医疗研究工作者对目前所使用的氧气湿化瓶的研究及试验证明，氧气湿化瓶装置又是极易被患者污染带菌的感染源，造成医院内感染，大量文献报道，临床上氧气湿化液及氧疗管道感染程度严重，以前医院普遍采用的是重复式氧气湿化瓶，该产品沿用多年，存在以下问题：一是对集中供氧系统、供氧管道中滋生的难忍异味无除味功能，二是湿化瓶需要每天消毒，湿化液需要每天更换，这样极大的加重了护士的工作量，三是虽然每天消毒，但在晾干和保存环节仍然存在污染的可能，增加了自身及交叉感染的可能性，四是氧气通过湿化液时产生大量气泡，破裂后产生噪声，不利于患者休息。The artificially prepared medical oxygen is extremely dry. If the medical oxygen is inhaled directly, it will cause the patient’s respiratory tract to be dry and uncomfortable. Therefore, the oxygen humidification device in the oxygen delivery equipment has become a necessary link in the oxygen inhalation process of the patient, and it is an indispensable medical device in the hospital. One, medical research workers' research and tests on the currently used oxygen humidification bottle prove that the oxygen humidification bottle device is also a source of infection that is easily contaminated by patients and causes nosocomial infection. A large number of literature reports, clinically Oxygen humidification fluid and oxygen therapy pipelines are seriously infected. In the past, hospitals generally used repetitive oxygen humidification bottles. This product has been used for many years. There is no deodorization function for peculiar smell. Second, the humidification bottle needs to be disinfected every day, and the humidification solution needs to be replaced every day, which greatly increases the workload of nurses. Third, although it is disinfected every day, there is still contamination during drying and storage. Possibly, the possibility of self-infection and cross-infection is increased. Fourth, when oxygen passes through the humidification liquid, a large number of bubbles are generated, and noise is generated after the rupture, which is not conducive to the patient's rest.
为解决上述问题，特别是除去集中供氧系统、供氧管道及病房终端在输氧时的异味，避免氧气湿化装置受到污染、氧气湿化不均匀及气泡破裂产生的噪声，发明本医用密闭式氧气除味湿化减噪装置。In order to solve the above problems, especially to remove the peculiar smell of the centralized oxygen supply system, oxygen supply pipeline and ward terminal during oxygen delivery, and to avoid the pollution of the oxygen humidification device, the uneven oxygen humidification and the noise caused by the bubble burst, the medical airtight Oxygen deodorization humidification noise reduction device.

在除味滤芯2下端设置氧气过滤均布器6及氧气缓冲区7，氧气过滤均布器6采用0.2um孔径的PTFE材料，不但能有效过滤氧气中的杂质、病菌，当氧气经过氧气缓冲区7及气泡透过氧气过滤均布器6后，将较大的氧气泡破碎成大小基本一致的小气泡，由湿化瓶底部自下而上逆流穿越湿化物质，增加了氧气湿化时间，扩大了氧气接触湿化物质的面积，提高了湿化效果，同时也避免了氧气大气泡破裂时产生的噪声，影响患者的休息。An oxygen filter uniform distributor 6 and an oxygen buffer zone 7 are arranged at the lower end of the deodorizing filter element 2. The oxygen filter uniform distributor 6 is made of PTFE material with a pore size of 0.2um, which can not only effectively filter impurities and germs in the oxygen, but also when oxygen passes through the oxygen buffer zone 7 and after the air bubbles pass through the oxygen filter uniform distributor 6, the larger oxygen bubbles are broken into small bubbles of basically the same size, and the humidification material is countercurrently passed through the humidification material from the bottom of the humidification bottle, which increases the oxygen humidification time. It expands the area where the oxygen contacts the humidified substance, improves the humidification effect, and also avoids the noise generated when the large oxygen bubbles burst, which affects the rest of the patient.
本发明彻底解决了在临床输氧时，医院集中供氧系统、氧气源、供氧管道、病房终端因长时间使用滋生的难以忍受的异味，同时也合理解决了传统氧气湿化吸入装置是开放式的，反复消毒使用，容易污染而引起院内感染，氧气湿化效果不佳，呼吸道干燥，湿化气泡噪声大，影响患者休息，护理工作烦琐，工作量增加，科室额外增加消毒液、冲洗液、湿化液、湿化瓶的成本。The invention completely solves the unbearable peculiar smell caused by the long-term use of the hospital's centralized oxygen supply system, oxygen source, oxygen supply pipeline, and ward terminal during clinical oxygen delivery, and also reasonably solves the problem that the traditional oxygen humidification inhalation device is open Repeated disinfection and use are easy to cause nosocomial infection due to pollution, poor oxygen humidification effect, dry respiratory tract, and large noise of humidification bubbles, which affect the patient's rest. The nursing work is cumbersome and the workload increases. The cost of humidification fluid and humidification bottle.
如上所述，本发明采用一体式设计、一次性使用、结构简单、无菌密封、生产成本低、使用方便、安全性高，具有很强的实用性和推广价值。As mentioned above, the present invention adopts one-piece design, one-time use, simple structure, aseptic sealing, low production cost, convenient use, high safety, and has strong practicality and popularization value.
