flutter valve การใช้

The flutter valves or Pneumostat valves allow patients to ambulate more easily and patients may be able leave the hospital in certain instances.
In 1962, Heimlich invented the chest drainage flutter valve ( also called the Heimlich valve ) and in 1969 was granted a patent for the device.
He also invented the Micro Trach portable oxygen system for ambulatory patients and the Heimlich Chest Drain Valve, or " flutter valve, " which drains blood and air out of the chest cavity.
The flutter valve is placed in the appropriate orientation ( most packages are designed so the valve can only be connected in the appropriate orientation ) and the pneumothorax is thus evacuated from the patient's chest.
A "'flutter valve "'( also known as the "'Heimlich valve "'after its inventor, Henry Heimlich ) is a one-way valve used in respiratory medicine to prevent air from travelling back along a chest tube.
