Puncture needle used for emergency puncture of tension pneumothorax

Abstract

The invention discloses a puncture needle for emergency puncture of tension pneumothorax. The puncture needle comprises an outer frame, positioning mechanisms and sealing mechanisms. The positioning mechanisms are arranged by two in total; the sealing mechanisms are arranged by two in total; the outer frame is of a hollow cylinder-shaped structure; a first moving through opening is formed in a position, near the edge of one end, on the outer surface of the outer frame; and a second moving through opening is formed in a position, located above the first moving through opening, on the outer surface of the outer frame. According to the puncture needle, by pushing a paddle in the first moving through opening, a telescopic tube can effectively drive a sealing ring according to a reading of a graduation pointer in a graduation groove to do effective movement for certain length, and then, length that a needle head can actually pierce into the body of a patient can be effectively adjusted; andmeanwhile, the position of the adjusted telescopic tube can be effectively fixed by the positioning mechanisms close to the needle head, so that a doctor lacking of practical operating experience canalso accurately make the needle head with certain length pierce into a lesion site of the patient.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a puncture needle for emergency puncture of tension pneumothorax. Background technique [0002] Tension pneumothorax refers to a large alveolar rupture or a large and deep lung laceration or bronchial rupture, the breach communicates with the pleural cavity and forms a one-way valve, also known as high pressure pneumothorax, air enters from the breach during inhalation In the pleural cavity, when the valve is closed during exhalation, the air in the cavity cannot be discharged, causing the pressure in the pleural cavity to rise continuously, oppressing the lung to gradually collapse, and pushing the mediastinum to the healthy side, squeezing the healthy side lung, resulting in Severe impairment of breathing and circulation. If the high-pressure air in the pleural cavity is squeezed into the mediastinum, it spreads to the subcutaneous tissue, forming subcutaneous emphys...

AI Technical Summary

Problems solved by technology

If the high-pressure air in the pleural cavity is squeezed into the mediastinum, it spreads to the subcutaneous tissue, forming subcutaneous emphysema in the neck, face, chest, etc. At the same time, if the patient has a pneumothorax, the lung compression is not serious after inspection, and breathing is not felt It is very difficult. After observation, the lungs have not continued to be compressed, that is, the gas in the pleural cavity has not increased further. Such patients may not necessarily be treated with puncture, intubation, drainage, and inspection tubes. Lung re-expansion also achieves the purpose of treatment. However, in the prior art, due to the use of puncture needles, experienced doctors are required to accurately puncture a certain length of needle into the patient's diseased part, and then effectively insert the needle into the patient's body. The gas is drawn out, so that doctors who lack practical operation experience cannot accurately penetrate the patient's body with a needle of appropriate length. After the needle device is actually inserted into the patient's body, it may be that the wound is too large, so that the outside air can enter the patient's body through the wound, which will adversely affect the actual exhaust effect of the device to a certain extent, so that the actual treatment of the patient is not good, and the existing puncture Due to the limitation of the actual structure of the needle equipment, when the patient is actually punctured, the needle of the equipment is easy to come into contact with the hands of the doctor and the external environment, so that the wound of the patient may be infected by germs, which brings great harm to the actual treatment of the patient. adverse effects
