技术领域technical field
本发明属于医疗器械技术领域，尤其是涉及一种多功能胃管导丝。The invention belongs to the technical field of medical devices, in particular to a multifunctional gastric tube guide wire.
背景技术Background technique
目前临床上胃管都是盲插，很大程度上依赖于操作人员的工作经验，如果插入太深，容易对患者胃部造成不适，如果插入太浅，又容易引起患者的误吸，并不能判定胃管是否准确插到胃里面的合适位置处，因此盲插操作使得插管手术存在一定的风险，另外，胃液的PH为2左右，呈强酸性，跟呼吸道的PH弱碱性值有明显区别，某些情况下需要对胃液进行检测时，有时患者胃液比较少，很难将其回抽出来进行检测。At present, the gastric tube is blindly inserted in clinical practice, which largely depends on the working experience of the operator. If it is inserted too deeply, it will easily cause discomfort to the patient's stomach. To determine whether the gastric tube is accurately inserted into the appropriate position in the stomach, so the blind insertion operation brings certain risks to the intubation operation. In addition, the pH of gastric juice is about 2, which is strongly acidic, which is obviously similar to the pH of the respiratory tract. The difference is that in some cases, when gastric juice needs to be tested, sometimes the patient's gastric juice is relatively small, and it is difficult to withdraw it for testing.
