Pneumothorax exhaust device for emergency internal medicine department

Abstract

The invention discloses a pneumothorax exhaust device for an emergency internal medicine department, and belongs to the technical field of medical instruments. The device comprises a fixed barrel; anadjusting barrel is movably connected to the interior of the fixed barrel; two fixed blocks are fixedly connected to the outer side wall of the top end of the adjusting barrel; screw sleeves are fixedly embedded into the fixed blocks; screw rods are in screw transmission connection with the interiors of the screw sleeves; and the bottom ends of the screw rods are rotationally connected to the interiors of bearings. The pneumothorax part of a patient can be subjected to active exhaust work, and once a squirrel-cage type motor stops working, a foot pump does not actively suck out gas in the pneumothorax part any more, namely the exhaust work can be stopped, so that the situation that the single exhaust amount is too large is prevented; continuous drainage gas accumulation can be carried out,so that the gas can be slowly drained out, generally reexpansion pulmonary edema does not occur, the single exhaust amount can be controlled, and the controllability is relatively good; and a plungeris actively attached to a sealing base under the action of a reset spring, and a plunger hole is sealed, so that the gas can be effectively prevented from returning into the pneumothorax part again,and the exhaust effect is better.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a pneumothorax exhaust device for emergency internal medicine. Background technique [0002] Emergency department refers to the emergency department of a hospital, which means emergency treatment. It is divided into emergency treatment and rescue. Its existence ensures that we can get professional and scientific treatment in the fastest time in case of sudden illness or accidental injury. Internal medicine is a specialty of clinical medicine, which is the foundation of almost all other clinical medicines. Symptoms, signs, laboratory diagnosis, imaging examination, differential diagnosis, diagnosis, treatment, prognosis.

Problems solved by technology

[0003] At present, gas enters the pleural cavity, resulting in a state of pneumothorax, which is called a pneumothorax. When a patient develops a pneumothorax, timely exhaust treatment is required, but the existing exhaust device has poor adjustability, and the single exhaust The amount is uncontrollable. When the amount of gas is large, excessive exhaust at one time may easily cause reexpansion pulmonary edema, which may easily cause secondary injuries.
