Description

An integrated intelligent laryngeal mask with pH and temperature monitoring functions

Technical field

The invention relates to the field of medical equipment, in particular to an integrated intelligent laryngeal mask with pH and temperature monitoring functions.

Background technique

Laryngeal mask, as a medical device for maintaining patients' breathing and ventilation, has the characteristics of non-invasive airway, and is widely used in clinical first aid 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 internal temperature and pH of the larynx cavity while performing normal ventilation.

The relatively constant body temperature is one of the important conditions for maintaining the normal life activities of the human body. For example, when 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.

Under normal physiological conditions, the body's acid-base imbalance is not easy to occur. Once the pH of the body fluid is lower than 7.35, it is already acidosis. The early symptoms often manifest as loss of appetite, nausea, vomiting, abdominal pain and other symptoms. Further development may manifest as lethargy. , Irritability, lack of energy. Due to the obvious difference between the pH of the gastric juice and the pH of the mucous membrane of the throat, real-time monitoring of the pH at the entrance of the esophagus can use a sudden change in pH to alert the gastric juice to recurrent behavior. Under normal circumstances, the pH value at the entrance of the esophagus should be around 6.5. When there is gastroesophageal reflux, the stomach contents will 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 in patients are equipped with drainage cavities, which reduces 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, it is often impossible to detect the occurrence of reflux in time. It was only discovered after the patient had aspirated. And reflux aspiration is a serious complication of general anesthesia with laryngeal mask. Therefore, it is very necessary to develop an integrated intelligent laryngeal mask with the function of monitoring temperature and pH. Through the real-time monitoring of the pH value at the entrance of the esophagus through the laryngeal mask, reflux can be detected in time, treated in time, and prevented from aspiration. of.
