具体实施方式Detailed ways
为使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图对本实用新型实施方式作进一步地详细描述。In order to make the purpose, technical solutions and advantages of the present utility model clearer, the implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings.
实施例1Example 1
如图3所示，本实用新型实施例提供了一种可监测呼气末二氧化碳分压的双孔鼻导管吸氧装置，包括一对可置于鼻孔1的空心的氧气出口端2、与出口端2连接的空心连接部3、设于鼻孔处的二氧化碳监护仪采样管5和监护仪6，连接部3通过氧气皮管4连接供氧装置，二氧化碳监护仪采样管5连接监护仪6，还包括设于所述连接部中的细采样管7，细采样管7一端深入到氧气出口端2中，另外一端伸出连接部3，并由一连接管8连接二氧化碳监护仪采样管5。As shown in Figure 3, the embodiment of the present invention provides a dual-hole nasal catheter oxygen inhalation device capable of monitoring end-tidal carbon dioxide partial pressure, including a pair of hollow oxygen outlet ports 2 that can be placed in nostrils 1, and outlet The hollow connection part 3 connected to the end 2, the carbon dioxide monitor sampling tube 5 and the monitor 6 arranged at the nostril, the connecting part 3 is connected to the oxygen supply device through the oxygen leather tube 4, the carbon dioxide monitor sampling tube 5 is connected to the monitor 6, and It includes a thin sampling tube 7 arranged in the connecting part, one end of the fine sampling tube 7 goes deep into the oxygen outlet port 2, and the other end extends out of the connecting part 3, and a connecting tube 8 is connected to the sampling tube 5 of the carbon dioxide monitor.
所述细采样管分别深入到所述一对氧气出口端中。所述连接管中设有多层滤纸9。还包括一固定器10，所述固定器将所述细采样管和所述连接管固定在所述连接部上。The thin sampling tubes respectively penetrate into the pair of oxygen outlet ports. Multiple layers of filter paper 9 are arranged in the connecting pipe. A fixer 10 is also included, and the fixer fixes the fine sampling tube and the connecting tube on the connecting part.
细采样管7为置入氧气出口端2的较细塑料管道，材质同留置套管针的套管部分。该采样管7和二氧化碳监护仪采样管5的连接部8是临床上常用的接口，大小与接头5正好匹配，使用留置套管针的输液接口端即可实现此功能。在连接部8的内部放置多层滤纸9，具有过滤细菌、病毒和水汽，避免交叉感染，防止采样管堵塞等作用。多层滤纸9可使用临床上常用的细菌过滤器（即人工鼻）中的滤纸材料实现。固定器10可以将部件7、8与部件3进行固定。The thin sampling tube 7 is a thinner plastic pipe inserted into the oxygen outlet port 2, and the material is the same as the cannula part of the indwelling trocar. The connecting part 8 of the sampling tube 7 and the sampling tube 5 of the carbon dioxide monitor is an interface commonly used in clinical practice, and its size matches the joint 5. This function can be realized by using the infusion interface end of the indwelling trocar. Multiple layers of filter paper 9 are placed inside the connecting portion 8, which can filter bacteria, viruses and water vapor, avoid cross-infection, and prevent sampling tubes from being blocked. The multi-layer filter paper 9 can be realized by using the filter paper material in a clinically commonly used bacterial filter (ie, an artificial nose). The holder 10 can fix the components 7 , 8 and the component 3 .
进行气体分压采样测定时，数值的精确程度可能会有影响。原因在于，有别于呼吸机环路和麻醉机环路，该吸氧装置是相对开放的。因此，有部分空气和氧气可能会和呼出气体一起进入监测孔，所以实测ＰＥＴＣＯ2从理论上来讲应该会低于真实ＰＥＴＣＯ2。When performing gas partial pressure sampling and determination, the accuracy of the value may be affected. The reason is that, unlike the ventilator loop and the anesthesia machine loop, the oxygen inhalation device is relatively open. Therefore, some air and oxygen may enter the monitoring hole together with the exhaled gas, so the measured PETCO 2 should be lower than the real PETCO 2 theoretically.
实施例2Example 2
如图4所示，与实施例1不同的是，将细采样管深入到其中一个氧气出口端，连接部分为两部分，一对氧气出口端分别位于连接部的两部分上，细采样管位于连接部的其中一个部分中，且仅未设有细采样管的连接部部分连接供氧装置。As shown in Figure 4, the difference from Example 1 is that the fine sampling tube is inserted deep into one of the oxygen outlet ports, and the connection part is divided into two parts, and a pair of oxygen outlet ports are respectively located on the two parts of the connection part, and the fine sampling tube is located at the two parts of the connection part. In one part of the connection part, only the part of the connection part without the fine sampling tube is connected to the oxygen supply device.
将一侧鼻孔作为吸氧端，一侧鼻孔作为监测端，左右用隔断11进行分隔，可有效减少氧气流量对于监测结果的影响。Using one nostril as the oxygen inhalation end and one nostril as the monitoring end, and separating the left and right sides with the partition 11 can effectively reduce the influence of oxygen flow on the monitoring results.
以上所述仅为本实用新型的较佳实施例，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
