Thoracentesis air-extraction device for treating pneumothorax

Abstract

The invention relates to a thoracentesis air-extraction device for treating pneumothorax. The air-extraction device includes a puncture needle, a warning tube and an air exhaust pipe; the puncture needle includes a needle core, a needle sheath and a needle base; the needle base is a right angle tee tube; a rubber soft plug is fixed inside the upper end of the straight tube of the needle base, andthe other end is fixedly connected to the needle sheath; the branch tubes are connected to the warning tube and the air exhaust pipe with soft tubes; the needle sheath is a plastic tube of which external diameter is gradually tapered from the head end to the tail end; the needle core penetrates into the rubber soft plug from the tail end of the needle seat and penetrates out from the needle sheath; the warning tube is a transparent tube, the bottom surface of the warning tube is provided with a small round tube connecting needle seat, the other end of the warning tube is open, and an elastic silicone membrane is fixed inside the warning tube; the air exhaust pipe is a hollow cylindrical tube, and small round tubes are fixed on the two ends of the air exhaust pipe, wherein the small round tube on one end is connected to the needle seat, and the small round tube on the other end is assembled with a silicone sleeve; and a unidirectional membrane and dustproof cloth are fixed in the air exhaust pipe. The air-extraction device is used for the air-extraction treatment of the pneumothorax; and the air-extraction device is simple in structure and convenient in using and can carry out the first aid and long-term treatment of the pneumothorax.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a thoracentesis air extraction device for treating pneumothorax. Background technique [0002] Pneumothorax (pneumothorax) refers to the gas into the pleural cavity, resulting in a state of pneumothorax, known as pneumothorax. The lung tissue and visceral pleura are usually ruptured due to lung disease or external force, or the tiny emphysema bubbles near the lung surface are ruptured, and the air in the lungs and bronchi escapes into the pleural cavity. Those caused by chest wall or lung trauma are called traumatic pneumothorax; those caused by spontaneous rupture of lung tissue due to disease are called "spontaneous pneumothorax", and those caused by artificially injecting air into the pleural cavity for treatment or diagnosis are called "artificial pneumothorax". Pneumothorax can be divided into closed pneumothorax, open pneumothorax and tension pneumothorax. Spontaneous pneum...

Problems solved by technology

[0005] (1) The volume of the device is too large, the structure is complicated to use, and it is inconvenient to carry. If the patient is in a life-threatening situation such as a disaster or a car accident, the tension pneumothorax cannot be treated in time, which will delay the rescue of the patient;
