Description

Technical Field

[0001] The utility model relates to the technical field of medical first-aid devices, in particular to a first-aid device for pneumothorax care. Background Art

[0002] Tension pneumothorax refers to the rupture of a large pulmonary bulla or a large and deep pulmonary laceration or bronchial rupture, with the rupture communicating with the pleural cavity and forming a one-way valve, also known as high-pressure pneumothorax. During inspiration, air enters the pleural cavity through the rupture, while during expiration, the valve closes and the air in the cavity cannot be discharged, resulting in a continuous increase in the pressure in the pleural cavity, compressing the lung and causing it to gradually collapse, pushing the mediastinum towards the healthy side, squeezing the healthy lung, and causing serious disorders in respiratory and circulatory functions. If the high-pressure air in the pleural cavity is squeezed into the mediastinum and spreads to the subcutaneous tissue, it will cause subcutaneous emphysema in the neck, face, chest, etc. The first-aid treatment principle for tension pneumothorax is to immediately exhaust air and reduce the pressure in the pleural cavity. An emergency device is required for the care of pneumothorax.

[0003] In the prior art, a pneumothorax first-aid device for cardiothoracic surgery care with the authorized publication number of CN217828495U, a outer needle tube is fixedly inserted through the inside of the pressing disc, an inner needle tube is slidably inserted at the lower end of the outer needle tube, and an inner threaded knob is rotatably connected to the upper end of the outer needle tube. The upper end of the inner needle tube is fixed with an outer threaded tube, and the inner threaded knob is rotationally connected to the outer threaded tube through a thread. The upper end of the outer threaded tube is communicated with an air outlet pipe, and two one-way valves are installed at the upper and lower positions inside the air outlet pipe. By rotating the inner threaded knob, the outer threaded tube and the inner needle tube are driven to move upward, so that the inner needle tube retracts inside the outer needle tube. When the outer needle tube is completely inserted into the chest cavity, the inner needle tube retracts inside the outer needle tube, which can prevent the tip of the inner needle tube from stabbing the internal organs and greatly improves the safety of using the device.

[0004] In the above technical solution, during use, the first-aid device needs to be fixed on the patient's body part. After the first-aid device is fixed, the puncture site for pneumothorax cannot be adjusted again, and it is necessary to remove the device for adjustment, which greatly limits the use of the first-aid device. For this reason, we propose a first-aid device for pneumothorax care. Content of the Utility Model
