Respiratory support airway clearing device for critical medicine department
Technical Field
The invention relates to the technical field of medical instruments, in particular to an airway clearing device for respiratory support of a severe medical department.
Background
The patency of the airway is usually reflected by the flow of breathing gas, the gas flow is in direct proportion to the diameter of the airway, and the larger the diameter of the airway is, the more unobstructed the flow is; otherwise, the airway is spasm, stenosis or blockage, the diameter of the airway becomes smaller, and the gas flow is slowed down. In general, the above theory is correct, but ignores another important factor. The gas flow rate is related to the driving pressure of the gas flow, in addition to the pipe diameter. The higher the driving pressure, the faster the gas flow rate for the same pipe diameter. Therefore, it is not comprehensive to reflect airway patency with gas flow alone. Airway resistance checks may remedy this deficiency. In the critical medical science department, the most common medical means is to breathe management and breath support for acute respiratory insufficiency and other various critical patients, but the breathing machine used at present can work effectively only under the condition that the airway is unobstructed, and many critical medical science department patients are often accompanied with the condition that respiratory tract phlegm or blood clots are blocked, so that the respiratory support treatment means is influenced, and great inconvenience is brought to doctor treatment and patients. The existing airway patency device has the following defects:
1. the patient needs to keep the respiratory tract continuously unobstructed, and the airway is kept unobstructed clinically by a head raising and neck raising method, wherein when the existing airway unobstructed device is inserted, one hand is placed on the forehead of the patient to enable the head to lean backwards, and the other hand is placed behind the neck of the patient to support the neck; the operation is complicated, the use is inconvenient, and the labor intensity is high;
2. when the patient encounters intraoral foreign matters (including secretions), the patient needs to be removed in time by a manipulation, the airway obstruction device usually sucks the intraoral foreign matters by negative pressure, the existing airway obstruction device cannot adjust air pressure, and the patient feels very strong discomfort.
3. The patient need breathe through the unobstructed ware of air flue after inserting the unobstructed ware of air flue, and the unobstructed ware of current air flue is direct to be connected with negative pressure device, and the patient can't breathe through the unobstructed ware of air flue, causes the patient to breathe the difficulty.
