Background

Pneumothorax refers to the state of qi accumulation caused by the entry of air into the pleural cavity, and is called pneumothorax. Many times, lung tissue and visceral pleura are ruptured by lung disease or external influences, or tiny air bubbles near the lung surface are ruptured, and air in the lung and bronchi escapes into the pleural cavity. Those caused by chest wall or lung trauma are called traumatic pneumothorax; spontaneous pneumothorax is caused by the self-rupture of lung tissue due to diseases, and artificial pneumothorax is caused by artificially injecting air into pleural cavity for treatment or diagnosis. Pneumothorax can be divided into closed pneumothorax, open pneumothorax and tension pneumothorax. Spontaneous pneumothorax is often seen in young and strong males or in patients with chronic bronchitis, emphysema and pulmonary tuberculosis. The disease belongs to one of the emergency diseases of the pneumology, serious patients can threaten life, and the patient can be cured by timely treatment. Tension pneumothorax refers to the rupture of large air bubbles in the lung or large and deep fissures in the lung or the rupture of bronchi, which are communicated with the pleural cavity and form a one-way valve, also known as hyperbaric pneumothorax. When breathing in, air enters into the pleural cavity from the gap, and when breathing out, the valve is closed, the air in the pleural cavity can not be discharged, so that the pressure in the pleural cavity is continuously increased, the lung is pressed to be gradually collapsed, the mediastinum is pushed to the healthy side, the healthy side lung is extruded, and serious obstruction of breathing and circulation functions is generated. If the high-pressure air in the pleural cavity is squeezed into the mediastinum and diffused to the subcutaneous tissue, subcutaneous emphysema is caused at the neck, face, chest and other parts. The emergency treatment principle of the tension pneumothorax is to exhaust air immediately and reduce the pressure in the pleural cavity. At present, a puncture needle with an exhaust hole is usually adopted for puncture and exhaust, however, the puncture needle is kept in the chest cavity of a patient for a long time, and the needle head easily punctures internal organs to influence the treatment effect.

For a better understanding of the features and technical solutions of the present invention, as well as the specific objects and functions attained by the present invention, reference is made to the accompanying drawings and detailed description of the invention.

As shown in fig. 1-14: an pneumothorax first-aid device for war trauma patients, comprising a housing 1 and a puncture device 2; it is characterized in that the puncture device 2 comprises a puncture needle body 21, an exhaust device 22, a pressure monitoring device 23, a sealing device 24, an anesthesia device 25 and a limiting device 26; the shell 1 is in a circular tubular structure, the puncture needle body 21 is arranged inside the shell 1 along the axis of the shell 1, and the puncture needle body 21 is provided with a vent groove along the axis of the puncture needle body 21; the exhaust device 22 is arranged at the upper part of the puncture needle body 21, and the exhaust device 22 is used for discharging gas in pneumothorax through the puncture needle body 21 after the puncture needle body 21 completes puncture; the pressure monitoring device 23 is arranged at any side of the puncture needle body 21, and the pressure monitoring device 23 determines that the puncture needle body 21 enters the pneumothorax of the patient through the pressure change in the puncture needle body 21; a sealing device 24 is arranged on the shell 1, and the sealing device 24 is used for preventing the outside air from contacting with the puncture needle body 21; the anesthesia device 25 is arranged on the side wall of the puncture needle body 21, an anesthesia medicament is arranged in the anesthesia device 25, and the anesthesia device 25 is used for performing anesthesia on the puncture position of the patient; a limiting device 26 is arranged in the housing 1, and the limiting device 26 is used for preventing the puncture needle body 21 from sliding when treating a patient.

In war, most patients are in open pneumothorax, and the onset of disease is fast, so the patients need to be treated quickly. When the first-aid device is used, the puncture device 2 is used for puncturing the patient quickly, and the gas in the pneumothorax of the patient is released. The puncturing device 2 works on the principle that the sealing device 24 on the housing needs to be detached first, then the first and second ribs of the patient are found, and the housing 1 is arranged vertically so that the housing 1 is located between the first and second ribs. The side of the puncture needle body 21 facing away from the air discharge device 22 is then brought closer to the patient's body and is no longer pressed when the side of the housing 1 comes into contact with the patient's body. Because the puncture needle body 21 can move along the axial direction of the shell 1 under the action of external force, after the shell 1 is placed on the body of a patient, the exhaust device 22 is pressed downwards, and at the moment, the exhaust device 22 can drive the puncture needle body 21 below the exhaust device to move under the action of external force. The puncture needle body 21 slowly extends out of the shell 1 under the action of external force, and the puncture needle body 21 in the shell 1 can be punctured into the body of a patient. Since the puncture needle body 21 enters the patient's body only, and the needle position of the puncture needle body 21 does not enter the pneumothorax, the pressure monitoring device 23 provided on the puncture needle body 21 side does not have a large pressure change. Along with the continuation of pricking of puncture needle head, the puncture needle head can produce certain painful sense to the patient, can anaesthetize patient's part through anesthesia device 25 that sets up on the puncture needle head lateral wall this moment, when using, in crowded into puncture needle head with the anesthetic in the anesthesia device 25, is discharged into patient's internally by puncture needle head with anesthetic afterwards to reach the effect of carrying out the anesthesia to the patient. When the puncture needle head continues to go deep and finally reaches the pneumothorax position, the air in the pneumothorax can not be discharged, and every time the patient inhales the air, the air in the pneumothorax is increased, so that the lung is pressed. So that the gas pressure in the chest will be high. Therefore, after the puncture needle body 21 reaches the pneumothorax position, the gas in the pneumothorax can rush into the puncture needle head, and the exhaust device 22 is in a closed state at this time, because the rescuer can rapidly judge whether the puncture needle head enters the pneumothorax position through the pressure monitoring device 23. When the air discharge device 22 is in the closed state and the puncture needle body 21 reaches the pneumothorax position, the pressure value displayed by the pressure monitoring device 23 disposed on the side wall of the puncture needle body 21 is suddenly increased, which indicates that the puncture needle body 21 has entered the pneumothorax position. Subsequently open exhaust apparatus 22 fast, the gas of gathering in patient's thorax can be discharged through exhaust apparatus 22 on puncture needle body 21, utilizes the stop device 26 that sets up in casing 1 to carry out spacingly to puncture needle body 21 afterwards for puncture needle body 21 can not take place to slide along the axis of casing 1 after accomplishing the puncture, has avoided the damage of puncture needle body 21 to patient's viscera when the treatment. The air exhausting device 22 has a unidirectional property, that is, the air in the puncture needle can be exhausted through the air exhausting device 22, but the outside air can not enter the puncture needle through the air exhausting device 22, so that the condition that germs in the outside air enter the patient body to cause infection during puncture is prevented. Make the personnel of suing and labouring can judge fast whether the puncture needle reaches pneumothorax position through pressure monitoring device 23, can also avoid causing the condition appearance that the patient infects when the puncture simultaneously.
