Description

Novel tension pneumothorax needle

Technical Field

The utility model relates to a medical article, in particular to a novel tension pneumothorax needle.

Background

When a human body breathes normally, negative pressure occurs when the lung is in an expansion state, and fresh air is pressed into the lung by pressure difference formed between the inside and the outside of the lung so as to maintain normal breathing. However, when a human body is subjected to trauma or has lung diseases, air enters a pleural cavity and compresses lung tissues, the air enters the lungs to cause the respiratory function to be damaged, and then the human body cannot breathe normally, which is called pneumothorax medically, the pneumothorax is also called as pneumoperitoneum puncture and lung burst, the traditional Chinese medicine disease is called as chest stuffiness and asthma, the air pressure in the pleural cavity is increased when the air pressure enters the pleural cavity, when the air pressure exceeds the range which can be borne by the human body, the lungs are squeezed, chest pain, chest distress, dyspnea and shock of a patient are caused, if the treatment is not carried out in time, the patient can die, and when the pneumothorax condition occurs, thoracentesis carried out to drain the air so as to ensure that the lung tissues are re-expanded, otherwise, the life risk can be endangered.

The main instrument used in thoracentesis is the thoracentesis package, the most prominent of which is the pneumothorax needle. The pneumothorax needle in the prior art is generally of a single-hole structure, and is easy to adhere to the wall or block with other gas tissues or organs in the thorax. In addition, the traditional pneumothorax needle has no depth mark, and complications such as blood vessel or nerve injury and the like easily occur during puncture, thereby bringing great inconvenience to the actual treatment process, having defects and being incapable of meeting the requirements of social development.

In view of the above, there is a need for a new type of tension pneumothorax needle to overcome the deficiencies of the prior art.

SUMMERY OF THE UTILITY MODEL
