Description

一种混氧系统A mixed oxygen system 技术领域Technical field
本发明涉及一种加温湿化呼吸设备技术领域装置，尤其涉及一种混氧系统。The invention relates to a device in the technical field of heating and humidifying breathing equipment, in particular to a mixed oxygen system.
背景技术Background technique
在呼吸设备领域内，就进行氧混合的仪器中，目前的技术有手动调节和自动调节两种结构。手动调节为参照调节表，找到对应的输出总流量下，氧气的给氧流量目标值，调整浮标流量计的旋钮，使指示数值达到目标值，等待一些时间，读取机器显示的氧浓度是否达到目标值，如有偏差再进行调整；这种调节方法等待时间长，目标氧浓度的误差范围也比较大；自动控制调节，及在高压氧气输入端增加一个比例阀，按照设置的氧浓度，流量，控制器智能调整比例阀的开度，并实时监测目标氧浓度。In the field of breathing equipment, the current technology for oxygen mixing instruments has two structures: manual adjustment and automatic adjustment. Manual adjustment refers to the adjustment table, find the target value of the oxygen supply flow of oxygen under the corresponding total output flow, adjust the knob of the buoy flowmeter to make the indicated value reach the target value, wait for some time, and read whether the oxygen concentration displayed by the machine is reached Adjust the target value if there is deviation; this adjustment method has a long waiting time, and the error range of the target oxygen concentration is also relatively large; automatic control adjustment, and a proportional valve is added to the high-pressure oxygen input terminal, according to the set oxygen concentration and flow rate , The controller intelligently adjusts the opening of the proportional valve and monitors the target oxygen concentration in real time.
以上两种形式的氧调节方式比较下来，自动控制结构更为智能，在实际临床中，也更容易操作使用。从现有技术中发现，现有的连接方法和转接装置存在操作不便，装拆费力，制造复杂困难的不足。在实际使用中氧模组进气口接入的氧源是高压氧，将氧控制模组放置外部，但其组装结构复杂，延长氧混路径，响应速度不及时。Comparing the above two types of oxygen regulation methods, the automatic control structure is more intelligent, and it is easier to operate and use in actual clinical practice. It is found from the prior art that the existing connection method and adapter device have the disadvantages of inconvenient operation, laborious assembly and disassembly, and complicated and difficult manufacturing. In actual use, the oxygen source connected to the air inlet of the oxygen module is hyperbaric oxygen, and the oxygen control module is placed outside, but its assembly structure is complicated, the oxygen mixing path is extended, and the response speed is not timely.
对比专利CN205759083U中，其调节装置的部件连接中，出现多个关节连接点，而这些关节连接点均为机械的连接；而在使用中，这些关节处均存在氧气泄漏的风险，机器内有很多电控部件，接头部分全部裸露在机器内，一旦发生泄漏，氧气全部排入机器内，会给机器造成很大的安全隐患；In the comparison patent CN205759083U, there are multiple joint connection points in the component connection of the adjusting device, and these joint connection points are all mechanical connections; and in use, there is a risk of oxygen leakage at these joints, and there are many inside the machine. The electrical control components and joints are all exposed in the machine. Once a leak occurs, all oxygen will be discharged into the machine, which will cause a great safety hazard to the machine;
