Description
技术领域technical field
本发明涉及一种医疗器械，尤其涉及主要应用于使用经鼻胃肠营养和经鼻气管镜操作时需要吸氧的患者的一种单腔高流量鼻导管。The invention relates to a medical device, in particular to a single-lumen high-flow nasal catheter mainly used for patients who need to inhale oxygen when using nasal gastrointestinal nutrition and nasal bronchoscopy.
背景技术Background technique
经鼻高流量鼻导管(HFNC，HighFlowNasalCannula)连接加温加湿高流量吸氧装置，可以为患者提供有湿化效果的高流量吸氧，经鼻输送气体会产生依赖气体流量的气道正压(PAP，PositiveAirwayPressure)，因而可以改善呼吸衰竭患者的氧合，减少患者呼吸做功，减少二氧化碳潴留，降低患者呼吸频率。双腔经鼻高流量鼻导管使用时可以产生气道正压，配合AIRVO-2呼吸湿化治疗仪或者文丘里及空氧混合器等高流量吸氧装置使用，可以为患者提供高流量吸氧，且吸氧温度、气体流量和氧浓度均可调。有研究证明(参见[Highflownasaloxygengeneratespositiveairwaypressureinadultvolunteers.AustCritCare.2007Nov；20(4):126-31.Epub2007Oct10.])，如果患者存在张口呼吸，则其产生正压作用大大降低。这表明使用双腔高流量鼻导管的时候，对密闭性有一定的要求，若使用时只用单腔通气而另一端空置，则达不到高流量鼻导管产生正压的作用。但是，双腔HFNC需要使用两个鼻孔进行吸氧，在需要进行一些特殊操作的时候，例如经鼻鼻饲营养或经鼻气管镜操作，双腔HFNC会干扰这些特殊操作的顺利进行，而这些特殊操作也可能影响双腔HFNC的吸氧效果。因此，现在缺少一种主要应用于使用经鼻胃肠营养和经鼻气管镜操作患者的高流量鼻导管，可以在保证吸氧治疗效果的同时，不影响经鼻胃肠营养和气管镜的操作。High-flow nasal cannula (HFNC, HighFlowNasalCannula) is connected to a heated and humidified high-flow oxygen inhalation device, which can provide patients with high-flow oxygen inhalation with humidification effect, and the delivery of gas through the nose will generate a positive airway pressure (PAP) that depends on the gas flow. , PositiveAirwayPressure), which can improve the oxygenation of patients with respiratory failure, reduce the patient's work of breathing, reduce carbon dioxide retention, and reduce the patient's respiratory rate. The double-chamber nasal high-flow nasal cannula can generate positive airway pressure when used. It can provide high-flow oxygen inhalation for patients when used with high-flow oxygen inhalation devices such as AIRVO-2 respiratory humidification therapy device or Venturi and air-oxygen mixer. And the oxygen inhalation temperature, gas flow and oxygen concentration can be adjusted. Studies have proved (see [Highflownasaloxygengeneratespositiveairwaypressureinadultvolunteers. AustCritCare. 2007Nov; 20(4):126-31.Epub2007Oct10.]), if the patient has mouth breathing, its positive pressure effect is greatly reduced. This shows that when using a double-lumen high-flow nasal cannula, there is a certain requirement for airtightness. If only one lumen is used for ventilation and the other end is left empty, the high-flow nasal cannula will not be able to generate positive pressure. However, double-chamber HFNC needs to use two nostrils for oxygen inhalation. When some special operations are required, such as nasal feeding nutrition or nasal bronchoscopy, double-chamber HFNC will interfere with the smooth progress of these special operations, and these special operations Operation may also affect the oxygen uptake effect of the dual-chamber HFNC. Therefore, there is currently a lack of a high-flow nasal cannula that is mainly used in patients who use nasal gastrointestinal nutrition and nasal bronchoscopy, which can ensure the effect of oxygen inhalation therapy without affecting the operation of nasal gastrointestinal nutrition and bronchoscopy .

下面结合附图和实施例对本发明进行详细的描述。The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
如图1～图3所示，本发明提供的单腔高流量鼻导管，主要应用于使用经鼻胃肠营养和经鼻气管镜操作时需要吸氧的患者，其包括一用于连接提供充足加温加湿气体管路的管接头1、一塑料(仅以此为例，并不限于此)导气管2、一出气管嘴3、一鼻塞定位套4、一鼻塞5和一对挂耳架6；其中，管接头1、导气管2和出气管嘴3依次连接，出气管嘴3侧面开设一出气口31，鼻塞定位套4套设在在出气管嘴3外部，鼻塞5直径为5-9mm，鼻塞5位于鼻塞定位套4的中部，正对并连通出气口31；挂耳架6对称设置在鼻塞定位套4的两侧，以将鼻塞定位套4固定在患者鼻孔下方。As shown in Figures 1 to 3, the single-lumen high-flow nasal catheter provided by the present invention is mainly used for patients who need oxygen inhalation when using nasal gastrointestinal nutrition and nasal bronchoscopy. Pipe joint 1 of heating and humidifying gas pipeline, a plastic (this is only an example, not limited to this) air guide tube 2, an air outlet nozzle 3, a nasal plug positioning sleeve 4, a nasal plug 5 and a pair of ear hangers 6; Wherein, the pipe joint 1, the air guide tube 2 and the air outlet nozzle 3 are connected in sequence, an air outlet 31 is opened on the side of the outlet nozzle 3, and the nasal plug positioning sleeve 4 is set outside the outlet nozzle 3, and the diameter of the nasal plug 5 is 5- 9mm, the nasal plug 5 is positioned at the middle part of the nasal plug positioning sleeve 4, facing and communicating with the air outlet 31; the ear hangers 6 are symmetrically arranged on both sides of the nasal plug positioning sleeve 4, so as to fix the nasal plug positioning sleeve 4 below the patient's nostrils.
根据患者自身情况，当使用鼻塞5给左侧鼻孔通气时，管接头1、导气管2和出气管嘴3等设备放置在患者左侧，然后将鼻塞定位套4套设在出气管嘴3上，右侧鼻孔则用于进行气管镜操作或经鼻胃肠营养；当使用鼻塞5给右侧鼻孔通气时，管接头1、导气管2和出气管嘴3等设备放置在患者右侧，然后将鼻塞定位套4套设在出气管嘴3上，左侧鼻孔则用于进行气管镜操作或经鼻胃肠营养。According to the patient's own situation, when the nasal plug 5 is used to ventilate the left nostril, the equipment such as the pipe joint 1, the airway tube 2 and the outlet nozzle 3 are placed on the left side of the patient, and then the nasal plug positioning sleeve 4 is set on the outlet nozzle 3 , the right nostril is used for bronchoscopy or nasal gastrointestinal nutrition; when the nasal plug 5 is used to ventilate the right nostril, the equipment such as the tube joint 1, the airway tube 2 and the outlet nozzle 3 are placed on the right side of the patient, and then The nasal plug positioning sleeve 4 is set on the outlet nozzle 3, and the left nostril is used for bronchoscopy or nasal gastrointestinal nutrition.
上述实施例中，出气管嘴3上设置有定位凹槽32，鼻塞定位套4通过定位凹槽32套设在出气管嘴3外部。In the above embodiment, the outlet nozzle 3 is provided with a positioning groove 32 , and the nasal plug positioning sleeve 4 is sleeved on the outside of the outlet nozzle 3 through the positioning groove 32 .
上述实施例中，鼻塞5包括S、M、L等多个尺寸型号，其中，尺寸型号为S的鼻塞5直径为5mm，尺寸型号为M的鼻塞5直径为8mm，尺寸型号为L的鼻塞5直径为9mm。In the above-mentioned embodiment, the nasal plug 5 includes multiple sizes such as S, M, L, etc., wherein the nasal plug 5 whose size is S has a diameter of 5 mm, the nasal plug 5 whose size is M has a diameter of 8 mm, and the nasal plug 5 whose size is L The diameter is 9mm.
上述实施例中，鼻塞定位套4、鼻塞5和挂耳架6为一体式结构，力学性能好，而且可以一体制成，制造简单方便。In the above-mentioned embodiment, the nasal plug positioning sleeve 4, the nasal plug 5 and the ear hanger 6 are of an integrated structure, which has good mechanical properties and can be made integrally, which is simple and convenient to manufacture.
本发明在临床使用时，首先根据患者的鼻孔尺寸选择鼻塞5的尺寸型号，以鼻塞5可以覆盖患者鼻孔截面积一半为依据选择合适尺寸型号的鼻塞5；根据患者自身情况，当使用鼻塞5给左侧或者右侧鼻孔通气，将管接头1、导气管2和出气管嘴3依次连接并放置在患者相对应的一侧，然后将鼻塞定位套4套设在出气管嘴3上，鼻塞5连通出气口31。然后将单腔高流量鼻导管进气端的管接头1连接加热呼吸管路末端，加热呼吸管路连接呼吸湿化治疗仪、文丘里或者空氧混合器，呼吸湿化治疗仪、文丘里或者空氧混合器连接氧气气源；将出气端的鼻塞5置入患者鼻孔中，同时通过两侧的挂耳架6将鼻塞定位套4固定在患者鼻孔下方，打开呼吸湿化治疗仪、文丘里或者空氧混合器，即可为患者提供有湿化效果的高流量吸氧。将气管镜或者鼻胃管插入患者的另一侧的鼻孔，在进行经鼻胃肠营养或经鼻气管镜操作的同时，起到一定程度的封闭鼻孔的作用。由于本发明只有一个相对于双腔高流量鼻导管更大的鼻塞5，患者只需要使用一个鼻孔进行吸氧，因此不影响经鼻胃肠营养和经鼻气管镜操作；对于经鼻气管镜操作和经鼻胃肠营养的患者，气管镜和鼻胃管起到了一个相对封闭鼻孔的作用，使得单腔高流量鼻导管同样可以产生一定的呼气末正压作用；通过体外实验验证，双腔高流量鼻导管和单腔高流量鼻导管在吸氧效果(产生PAP、吸入氧浓度)方面没有显著差异。When the present invention is used clinically, at first the size model of the nasal plug 5 is selected according to the size of the patient's nostrils, and the nasal plug 5 of a suitable size and model is selected on the basis that the nasal plug 5 can cover half of the patient's nostril cross-sectional area; according to the patient's own situation, when using the nasal plug 5 Ventilate the left or right nostril, connect the tube joint 1, the airway tube 2 and the outlet nozzle 3 in sequence and place them on the corresponding side of the patient, then set the nasal plug positioning sleeve 4 on the outlet nozzle 3, and the nasal plug 5 Connected to the air outlet 31. Then connect the pipe joint 1 at the inlet end of the single-lumen high-flow nasal catheter to the end of the heated breathing circuit, and the heated breathing circuit is connected to the respiratory humidification therapeutic apparatus, Venturi or air-oxygen mixer, and the respiratory humidification therapeutic apparatus, Venturi or air The oxygen mixer is connected to the oxygen source; put the nasal plug 5 at the air outlet into the patient's nostril, and at the same time fix the nasal plug positioning sleeve 4 below the patient's nostril through the ear hangers 6 on both sides, and turn on the respiratory humidification treatment instrument, Venturi or air The oxygen mixer can provide patients with high-flow oxygen inhalation with humidification effect. The bronchoscope or nasogastric tube is inserted into the other nostril of the patient, and it can seal the nostril to a certain extent while performing nasal gastrointestinal nutrition or nasal bronchoscopy. Since the present invention has only one nasal plug 5 that is larger than the double-lumen high-flow nasal catheter, the patient only needs to use one nostril for oxygen inhalation, so it does not affect the operation of nasal gastrointestinal nutrition and nasal bronchoscopy; for nasal bronchoscopy Compared with patients receiving nasogastric nutrition, the bronchoscope and nasogastric tube can relatively close the nostrils, so that the single-lumen high-flow nasal cannula can also produce a certain positive end-expiratory pressure; through in vitro experiments, the double-chamber There was no significant difference in oxygen inhalation effect (production of PAP, inspired oxygen concentration) between high-flow nasal cannula and single-lumen high-flow nasal cannula.
上述实施例仅用于说明本发明，其中各部件的结构、连接方式等都是可以有所变化的，凡是在本发明技术方案的基础上进行的等同变换和改进，均不应排除在本发明的保护范围之外。The above-described embodiments are only used to illustrate the present invention, wherein the structure of each component, connection mode, etc. all can be changed, and all equivalent transformations and improvements carried out on the basis of the technical solutions of the present invention should not be excluded from the scope of the present invention. outside the scope of protection.
