技术领域technical field
本实用新型涉及医疗器械，具体地指一种可测患者食管中段温度的胃管。The utility model relates to a medical device, in particular to a gastric tube capable of measuring the temperature of the middle section of the esophagus of a patient.
背景技术Background technique
在临床治疗中，需要对置入胃管的危重患者和手术患者的核心体温进行连续监测。体温是基本生命体征，危重患者和手术患者的体温易发生变化，必须密切监测，现实操作中对这一点的重视程度还不够。目前，临床医务人员对危重症和手术期高、低温的危害性认识尚有不足，而此类患者体温监测方法受到的众多因素影响，既不方便有时也不准确。因此体温监测常被忽视。重视危重症和手术患者体温监测对相关疾病防治具有重要意义，可提高患者医疗效果。常用的体温测量装置有：①体表温度计：体表温度计测量体表温度的影响因素很多，准确性较差；②鼻咽测温计(将温感探头从鼻腔放入病人的鼻咽中，然后连接到监护仪上，对病人进行鼻咽温测量)：鼻咽测温计测量的鼻咽温度与患者核心体温尚有一定的差距，且受到气流和进食饮水的影响；③直肠测温计：直肠测温计用于手术中连续测温不方便；④食管测温计(患者食管中段温度可代表核心体温)：食管测温计需将温度传感器置入食管中段，功能单一，仅能测温；⑤膀胱温度计：须经尿道置入温度传感器，受尿量影响较大；⑥气道内测温计：气道内测温计操作复杂，应用不便，较少应用。In clinical treatment, it is necessary to continuously monitor the core body temperature of critically ill patients with gastric tubes and surgical patients. Body temperature is a basic vital sign. The body temperature of critically ill patients and surgical patients is prone to change and must be closely monitored. In practice, not enough attention has been paid to this point. At present, clinical medical staff still have insufficient understanding of the dangers of high and low temperatures during critical illness and surgery, and the temperature monitoring methods of such patients are affected by many factors, which is inconvenient and sometimes inaccurate. Therefore, temperature monitoring is often neglected. Paying attention to temperature monitoring of critically ill and surgical patients is of great significance to the prevention and treatment of related diseases, which can improve the medical effect of patients. Commonly used body temperature measurement devices are: ① body surface thermometer: there are many factors affecting the body surface temperature measured by the body surface thermometer, and the accuracy is poor; Then connect to the monitor to measure the patient's nasopharyngeal temperature): there is still a certain gap between the nasopharyngeal temperature measured by the nasopharyngeal thermometer and the patient's core body temperature, and is affected by airflow and eating and drinking; ③ rectal thermometer : The rectal thermometer is inconvenient for continuous temperature measurement during surgery; ④ Esophageal thermometer (the temperature in the middle esophagus of the patient can represent the core body temperature): the esophageal thermometer needs to place the temperature sensor in the middle of the esophagus, which has a single function and can only measure ⑤ Bladder thermometer: A temperature sensor must be inserted through the urethra, which is greatly affected by urine volume; ⑥ Airway thermometer: The operation of an airway thermometer is complicated, inconvenient to use, and rarely used.
