Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a tracer-type cannula puncture needle. Background Art

[0002] Pneumothorax refers to a state of gas accumulation caused by the entry of gas into the pleural cavity due to various reasons. Because it will compress the lung tissue, it will cause blood-gas exchange dysfunction in the lungs. Patients often experience symptoms of chest pain, chest tightness and difficulty breathing. In severe cases (tension pneumothorax), due to the high pressure in the chest cavity, it can push against the mediastinum and compress the heart, causing symptoms such as cyanosis, rapid pulse, decreased blood pressure, and unconsciousness, which can quickly lead to death.

[0003] The existing pneumothorax puncture needle mainly comprises an inner needle core and an outer sleeve. During puncture, the inner needle core is inserted into the outer sleeve and inserted into the chest cavity together.

[0004] When people develop pneumothorax symptoms while out on picnics, field expeditions, or outdoor leisure activities, emergency treatment can be performed using a pneumothorax puncture needle. After the pneumothorax puncture needle is inserted into the chest cavity, the inner needle core is pulled out and the outer sleeve is left in place. In order to ensure that the position of the outer sleeve can be fixed after insertion to prevent displacement and reduce the risks and accidents caused by movement during medical treatment, the present application provides a tracer-type sleeve puncture needle to meet the needs.

When pneumothorax symptoms occur during outdoor outings, field explorations, outdoor leisure, etc. , emergency treatment is performed through a pneumothorax puncture needle. The preferred insertion position is the second intercostal space of the clavicle midline on the affected side of the thorax. Clean the determined position with an antibacterial solution, unscrew the hard shell storage shell of the kit, and pull out the pneumothorax puncture needle and its accessories. The pneumothorax puncture needle mainly includes an inner needle core 1 and an outer sleeve 2. During puncture, the inner needle core 1 is inserted into the outer sleeve 2 and inserted into the chest cavity together. Insert the decompression needle into the upper edge of the third rib and the skin above the clavicle midline, and insert it into the intercostal space at a 90° angle to the chest, ensuring that the tail end of the needle after entering the chest is not in the middle of the nipple line and is not facing the heart. Insert the puncture needle into the pleural cavity and listen to the sound of sudden air overflow during tension pneumothorax decompression. Pull out part of the inner needle core 1 and leave the outer sleeve 2 in place. Fix the tube body 201 on the chest according to local regulations. Closely monitor for recurrence and seek medical attention in time.
