A painless gastroscope with airtight ventilation anesthesia mask

Technical field

The utility model belongs to the technical field of medical devices, and in particular relates to a sealable ventilation anesthesia mask for painless gastroscopy.

Background technique

With the development of medical standards, patients have higher and higher requirements for comfortable medical treatment. Painless gastroscopy uses sedative and analgesic drugs during the operation to reduce or eliminate the nausea, vomiting, pain and other discomforts experienced by the patient during the gastroscopy operation. This painless gastroscopy technology is becoming more and more popular with patients, and its application in clinical practice is becoming more and more common. However, during painless gastroscopy, sedative and analgesic drugs can not only relieve the patient's pain, but may also inhibit the patient's breathing, causing the patient's breathing to become slower and shallower, the breathing rhythm to be unstable, and even apnea and severe apnea may occur at any time. Hypoxemia and suffocation threaten the patient's life. Therefore, it is necessary to continuously monitor the patient's respiratory rhythm and respiratory depth during painless gastroscopy. Once the patient's respiratory rhythm slows down and the respiratory depth becomes shallow, the dosage of anesthetic drugs can be reduced in time to reduce the suppression of breathing by anesthetic drugs and avoid the progression of respiratory depression to Severe hypoxemia and asphyxia.

In current painless gastroscopy, the existing anesthesia mask usually has a hole for the gastroscope tube to pass through. Since the gastroscope tube needs to stretch, there is still a gap between it and the hole. The anesthesia mask has poor airtightness, which not only cannot Monitoring the patient's respiratory rhythm and depth, and unable to provide emergency mask-sealed pressurized oxygen, increase the patient's risk of hypoxemia. Therefore, we propose a sealable ventilation anesthesia mask for painless gastroscopy.
