Abstract
Description
Technical Field
[0001] The invention relates to the field of medical devices, and in particular to an integrated intelligent laryngeal mask with pH and temperature monitoring functions. Background Art
[0002] As a medical device for maintaining the patient's breathing and ventilation, the laryngeal mask has the characteristics of non-invasive airway and is widely used in clinical emergency or resuscitation. The existing first-generation, second-generation and third-generation laryngeal masks are limited to effective artificial or mechanical ventilation and cannot measure the temperature and pH inside the laryngeal cavity while performing normal ventilation.
[0003] The relative constancy of human body temperature is one of the important conditions for maintaining normal life activities of the human body. If the body temperature is higher than 41 degrees Celsius or lower than 35 degrees Celsius, it will seriously affect the functional activities of various systems (especially the nervous system) and even endanger life. Clinically, checking the patient's body temperature and observing its changes are of great significance for diagnosing diseases or judging the prognosis of certain diseases.
[0004] Under normal physiological conditions, acid-base imbalance in the human body is not easy to occur. Once the pH value of body fluids is lower than 7.35, it is already acidosis. In the early stage, it is often manifested as loss of appetite, nausea, vomiting, abdominal pain and other symptoms. Further development may manifest as drowsiness, irritability, and lack of energy. Since the pH of gastric juice is significantly different from that of pharyngeal mucosal fluid, real-time monitoring of the pH at the entrance of the esophagus can use the sudden change of pH to warn of gastric reflux behavior. Under normal circumstances, the pH value at the entrance of the esophagus should be around 6.5. When there is gastroesophageal reflux, the gastric contents reflux to the entrance of the esophagus, and the pH value at the entrance of the esophagus will drop sharply. At present, most laryngeal masks used for patients are equipped with drainage holes, which reduce the risk of gastric juice reflux into the airway to a certain extent. However, because the entrance of the esophagus cannot be monitored in real time, the occurrence of reflux cannot be detected in time, and it is often discovered after the patient has aspiration. Reflux aspiration is a serious complication of laryngeal mask anesthesia. Therefore, it is very necessary to develop an integrated intelligent laryngeal mask with the function of monitoring temperature and pH. Through real-time monitoring of the pH value at the entrance of the esophagus, reflux can be detected and treated in time to prevent the occurrence of aspiration. Summary of the invention
