背景技术Background technique
眼科手术患者以老年人居多，随着人们对生活质量的要求不断提高及社会老龄化程度的加深，接受眼科手术治疗的患者不断增加。眼科手术除小儿及不能配合的特殊患者外，大多采用局部麻醉。局部麻醉的优点是快捷、方便、经济，患者术后反应轻。但眼科手术均为显微手术，患者在清醒状态下需绝对安静平卧，部分手术还需要配合手术，眼球按要求转动或固视。按无菌要求，内眼手术头面部到胸部铺设无菌巾2～3层，加上术眼粘贴手术薄膜，因此铺巾后口鼻部会紧贴布巾，患者有感觉憋闷、呼吸不畅等，即使给予鼻导管吸氧，也不能缓解患者的不适感。由于铺巾的不适更加重了患者紧张和恐惧心理，可引起交感系统兴奋、疼痛加剧，手术配合度随之降低，促使手术难度增加。传统的吸氧方式不适合手术病人的吸氧，如面罩吸氧及吊耳固定的双腔鼻导管吸氧会影响手术野的消毒范围，并可能干扰手术操作；鼻塞式鼻导管吸氧导管虽对手术野的消毒及手术操作影响较小，但鼻导管插入鼻孔并需用胶布黏贴固定，可能引起患者不适，造成术中患者躁动，给手术带来风险等。此外，国外有文献报道，铺巾下空气流动差，只有较少部分的二氧化碳通过铺巾和外界气体交换，同时紧张焦虑造成患者呼吸频率加快，均导致铺巾下患者头部附近二氧化碳浓度升高。常规流量的给氧不能有效控制二氧化碳的蓄积，随着手术时间的推延，患者重复吸入的二氧化碳量增加，可能造成动脉血二氧化碳分压升高，导致术中眼内压升高，容易引起手术并发症，对老年患者，还有诱发相关的心血管病变的风险，可能造成严重后果。因此改善铺巾下的呼吸环境，提供一种眼科手术用吸氧管支撑装置，能极大增加患者围手术期的安全性和舒适度，从而提高术者的满意度和手术的安全性。The majority of ophthalmic surgery patients are elderly people. With the continuous improvement of people's requirements for quality of life and the deepening of the aging society, the number of patients receiving ophthalmic surgery continues to increase. Except for children and special patients who cannot cooperate, most ophthalmic operations use local anesthesia. The advantages of local anesthesia are fast, convenient and economical, and patients have mild postoperative reactions. However, all ophthalmic operations are microscopic operations, and the patient needs to be absolutely quiet and supine in an awake state. Some operations also need to cooperate with the operation, and the eyeballs can be rotated or fixed as required. According to the aseptic requirements, 2 to 3 layers of sterile towels are laid from the head and face to the chest of the inner eye surgery, and the surgical film is attached to the surgical eye. Therefore, after the drape is laid, the mouth and nose will be close to the cloth towel, and the patient feels stuffy and has difficulty breathing. Even giving nasal cannula oxygen inhalation could not relieve the patient's discomfort. Because the discomfort of draping aggravates the patient's nervousness and fear, it can cause the sympathetic system to be excited, the pain will intensify, and the cooperation degree of the operation will decrease accordingly, which will increase the difficulty of the operation. Traditional oxygen inhalation methods are not suitable for surgical patients. For example, mask oxygen inhalation and double-chamber nasal cannula with fixed lugs will affect the disinfection range of the surgical field and may interfere with surgical operations; It has little impact on the disinfection of the surgical field and surgical operations, but the insertion of the nasal catheter into the nostril and the need to be fixed with adhesive tape may cause discomfort to the patient, cause restlessness during the operation, and bring risks to the operation. In addition, there are foreign literature reports that the air flow under the drape is poor, and only a small part of carbon dioxide is exchanged with the outside air through the drape. At the same time, nervousness and anxiety cause the patient's respiratory rate to increase, which all lead to an increase in the concentration of carbon dioxide near the head of the patient under the drape. . Conventional oxygen supply cannot effectively control the accumulation of carbon dioxide. As the operation time is delayed, the amount of carbon dioxide repeatedly inhaled by the patient increases, which may cause the partial pressure of carbon dioxide in the arterial blood to increase, resulting in an increase in the intraocular pressure during the operation, which is likely to cause surgical complications For elderly patients, there is also the risk of inducing related cardiovascular lesions, which may cause serious consequences. Therefore, improving the breathing environment under the drape and providing an oxygen inhalation tube support device for ophthalmic surgery can greatly increase the safety and comfort of the patient during the perioperative period, thereby improving the satisfaction of the operator and the safety of the operation.
近年来，患者的安全和舒适护理是关注的热点。随着国人人均寿命的提高，越来越多的高龄老人接受眼科手术治疗。国内研究报道，吸氧可以使眼科局麻手术患者围手术期血氧饱和度维持在较高水平，明显改善患者的憋闷、烦躁等症状，促进手术顺利进行，提高手术安全性。国内给氧方式主要为鼻导管吸氧，也有报道应用改良的面罩吸氧或吸氧面罩反方向放置口鼻部。近十年来国内研究的关注点主要是口鼻部铺巾支撑装置，主要有固定在手术床头的支架、固定在患者面部两侧或以患者肩、胸部为支撑点，伸出到口鼻部的钢丝支架，以及直接固定在口鼻部的托架等。该类装置均为金属材料制作，其应用可能受不同患者头面部大小及体形的限制，且支架直接接触面部皮肤或身体部位可能会有不适感甚至损伤等，存在诸多不足。In recent years, patient safety and comfort care have been the focus of attention. With the improvement of the average life expectancy of Chinese people, more and more elderly people are receiving ophthalmic surgery. Domestic studies have reported that oxygen inhalation can maintain the blood oxygen saturation of patients undergoing ophthalmic local anesthesia at a relatively high level during the perioperative period, significantly improve patients' symptoms such as depression and irritability, promote the smooth operation of the operation, and improve the safety of the operation. The domestic oxygen supply method is mainly nasal catheter oxygen inhalation, and it is also reported that an improved mask is used to inhale oxygen or the oxygen inhalation mask is placed in the opposite direction to the mouth and nose. In the past ten years, the focus of domestic research is mainly on the mouth and nose drape support device, which mainly includes brackets fixed on the head of the operating bed, fixed on both sides of the patient's face, or using the patient's shoulders and chest as support points, extending to the mouth and nose. Wire brackets, and brackets directly fixed on the nose and mouth. These devices are all made of metal materials, and their application may be limited by the size and shape of the head and face of different patients, and the direct contact of the bracket with the facial skin or body parts may cause discomfort or even damage, and there are many shortcomings.
