technical field

The utility model relates to the field of medical equipment, in particular to a visible intubation type positive pressure mask and a breathing system.

Background technique

During the operation of general anesthesia and tracheal intubation, the patient needs to perform mask-controlled positive pressure ventilation (during this period, the doctor uses the mask to hold the patient's mouth and nose, and administers anesthetics while the patient is breathing spontaneously or assisting ventilation, and waits until the patient reaches an appropriate level. After the depth of anesthesia is reached, intubation begins). However, in clinical practice, patients with various airway problems such as tongue hypertrophy, limited neck movement, reduced opening, tumor mass, etc. squeeze and stretch the airway, causing airway stenosis and position change, are often encountered. It is often faced with situations where assisted ventilation is difficult or even positive pressure ventilation cannot be performed after anesthesia.

Difficult airway has always been an unsolved problem in the field of anesthesia. A variety of endotracheal intubation devices and instruments have been released to address this type of problem, but little improvement has been made in the field of anesthesia masks. It has been found in clinical work that many patients with tongue hypertrophy and sleep apnea syndrome face a critical situation in which the tongue falls backward and blocks the airway after anesthesia induction, making it difficult to perform mask ventilation. In this case, if the subsequent tracheal intubation operation is not smooth, it will most likely lead to fatal events.

Lower endotracheal tube intubation.

Step 4. After the endotracheal tube intubation is completed, inflate the inflatable balloon 11 in the intubation balloon structure. Since there is no gas in the inflatable airbag 11 during the intubation operation, it is tightly wrapped around the wall of the gas intubation tube. After the intubation operation is completed, the inflatable airbag 11 provides gas (which can be oxygen) through the inflatable tube, and an inflatable airbag is formed on the top of the ventilator endotracheal tube. Dislodged or slipped out of the throat after successful insertion.
