Description

[0001] Variable capacity air mask bag unit [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air mask bag unit (AMBU) for artificially maintaining respiration of a patient having difficulty in voluntary breathing, Unit.

For emergency patients who have difficulty in voluntarily breathing, the tube is forced through the mouth or nose to the airway and artificially ventilated through the intubated tube. In general, this is called 'prayer intubation.' In the intensive care unit or emergency room of the hospital, air is injected into the tube using a machine called 'ventilator' to keep the patient's breathing artificially.

However, it is impossible to move the ventilator with the patient in the case of a medical facility without a ventilator to assist in ventilation of the patient who inserted the tube, or when the patient must be transported to another hospital or moved to another location for examination. Therefore, in this case, a tool called "Ambu (Air Mask Bag Unit)" is used to force air into the body through the tube which is intubated by the patient.

Ambu typically consists of a connector for connection to an air bag valve, mask or air intubated tube. If the air bag formed with a constant volume of the air bag is pressed with a physical force, the air in the air bag is forcibly injected into the patient's body through the tube, thereby artificially maintaining the breathing of the patient in which spontaneous breathing is difficult .

In the case of mechanical ventilation with a ventilator, etc., the machine can set the amount of air to be injected according to the patient's age, sex, and physical condition, so that it can be injected uniformly to the set amount. However, Ambu is a manually operated hand tool that adjusts the amount of air injected by the practitioner, making it difficult to inject air at the correct volume for the patient's physical condition.

Therefore, in hospitals, hospitals are equipped with Ambu by size (capacity) in case the volume of air to be injected at one time varies greatly, such as in adults or children. This is based on the amount of air that is pushed out to the maximum extent. Even if it is used, there is a limit in injecting the patient with proper volume of air according to different volume according to the patient's physical condition. Also, it is inconvenient in that a plurality of AMBUs must be provided for each size (capacity).
