Description

Tension Pneumothorax Gas Removal Device

The present invention relates to a gas removal device for tension pneumothorax, and more particularly, to a gas removal device for tension pneumothorax that can improve the effect of discharging the gas and at the same time prevent damage to the human body.

One common cause of death in trauma patients is tension pneumothorax. Tension Pneumothorax refers to an emergency disease in which the pneumothorax is severe and the heart is pushed to the other side, the blood of the veins cannot return to the heart, causing a shock condition and the lungs entering a state of dysfunction.

These tense pneumothorax can occur without trauma and can occur in single trauma accidents, mass disasters, and during combat. In particular, previous studies have reported that 33% of preventable deaths in combat are caused by tension pneumothorax.

In cases of tension pneumothorax, a common first aid is to insert a venous vascular catheter in the chest to remove the gas that compresses the lungs. However, previous studies have reported that these methods are not effective for gas release, and high viscosity materials such as blood are rarely emitted.

Especially in cases where constant positive pressure ventilation is required (coma and severe respiratory failure), the pneumothorax progresses faster, making this approach less practical. In addition, there is a problem that can cause pneumothorax if a sharp intravenous catheter is inserted in a state where pneumothorax is not clear. Therefore, in the case of emergencies that contend with angles (especially at emergency sites, mass disaster sites, and battlefields), there are recommendations to consider a finger thoracostomy, such as finger thoracostomy, in which a finger is inserted through a simple incision as soon as is urgent. If there is a risk that the operator can be exposed to hematogenous infections by being stabbed in the fracture, and if the tissue is tough and strong, the puncture itself can be difficult from the beginning, and it is difficult to maintain or manage the opening after the procedure. Chest tube intubation can also be considered, but it is not possible to have many surgical tools that need to be opened for each patient in the first aid site, mass disaster site, and the battlefield where treatment of tension pneumothorax is most needed. It can be considered impossible.
