Description
技术领域technical field

背景技术Background technique
近年来，随着国家逐渐放开二孩政策，大部分家庭选择生第二胎，但是经常会遇到不孕的情况，因此，宫腔镜手术是一个经常选择的手术方式。它成为妇科出血性疾病和宫内病变的首选检查方法，然而此种手术方式会对麻醉提出较高的要求。In recent years, as the country gradually liberalizes the two-child policy, most families choose to have a second child, but they often encounter infertility. Therefore, hysteroscopic surgery is a frequently chosen surgical method. It has become the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions. However, this surgical method puts forward higher requirements for anesthesia.
对于此种患者的麻醉方式，我们选择非插管型静脉全麻，一般选择芬太尼家族药物复合丙泊酚，给予这两个药物后患者一般会出现或轻或重的呼吸抑制，患者通过面罩吸氧，至于给药后患者是否有呼吸，我们一般通过观察胸廓起伏，或者观察脉搏氧饱和度，但是有时患者盖得被子较厚，无法很细微的观察到胸廓起伏情况，以及当我们观察脉搏氧饱和度时，如果患者脉搏氧饱和度已经下降到90%以下时，这时通过面罩加压给氧化的话，虽然对患者没有很大影响，但是缺氧也对患者部分组织的氧供产生了一定的副作用。另外，如果我们观察不及时会造成很严重的医疗事故。鉴于此，我们发明一种十分方便且易于监测患者呼吸的带导管面罩。For the anesthesia method for such patients, we choose non-intubated intravenous general anesthesia, and generally choose fentanyl family drugs combined with propofol. After the administration of these two drugs, patients generally experience mild or severe respiratory depression. Oxygen inhalation by face mask. As for whether the patient is breathing after administration, we usually observe the chest rise or pulse oxygen saturation. When the pulse oxygen saturation is reached, if the patient's pulse oxygen saturation has dropped below 90%, if the mask is pressurized to oxidize at this time, although it does not have a great impact on the patient, the hypoxia will also affect the oxygen supply of some tissues of the patient. certain side effects. In addition, if we fail to observe in time, it will cause serious medical accidents. In view of this, we invented a very convenient and easy to monitor the patient's breathing with a mask mask.
