Description

Technical Field

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

[0002] First aid for pneumothorax refers to the situation where after the patient's chest is damaged by external force, gas enters the pleural cavity, causing gas accumulation in the pleural cavity. The patient will experience symptoms such as pain and palpitations. As the patient's condition worsens, some patients are also prone to respiratory and circulatory disorders, which directly affect the patient's quality of life, and thus require emergency rescue. Pneumothorax is a critical and severe disease, and upon discovery, it requires immediate puncture to exhaust air and reduce the pressure in the pleural cavity.

[0003] In the existing emergency treatment for pneumothorax patients, a needle is usually used to puncture into the chest cavity to exhaust the gas. However, when the needle is inserted into the patient's body, medical staff can only rely on holding the needle tube to extract the gas by themselves. There is no effective fixing measure, and it is easy for the gas to shake and shift during extraction, which reduces the effect of gas extraction and is also easy to injure the patient's internal organs.

[0004] Therefore, a pneumothorax emergency device for cardiothoracic surgery nursing is proposed. Utility Model Content

[0005] The utility model aims to provide a pneumothorax emergency device for cardiothoracic surgery nursing to solve the problems raised in the above-mentioned background technology.

[0023] The fixing structure includes a plurality of rotating rods 7, which are rotatably mounted on the outer ring 11, and a sliding block 71 is rotatably mounted on the outer ring 11, and the sliding block 71 is slidably mounted on the inner ring 10. An arc-shaped clamping block 72 is mounted on the sliding block 71, and the arc-shaped clamping block 72 contacts the needle 16. A positioning groove 73 is provided on the inner ring 10, and the sliding block 71 is slidably mounted in the positioning groove 73. Retention grooves 75 are provided on the inner walls of both sides of the positioning groove 73. Limiting blocks 74 are installed on both sides of the sliding block 71, and the limiting blocks 74 are slidably mounted in the retention grooves 75. The chassis 9 is placed on the part of the patient's body that needs to be punctured, and is fixed with the anti-sensitive glue 13, and then the needle 16 is punctured into the patient's chest cavity through the chassis 9 and the inner ring 10, and punctured to a certain position When the needle 16 is in the correct position, the outer sleeve ring 11 is rotated, and the rotation of the outer sleeve ring 11 drives one end of the rotating rod 7 to move in an arc shape, and the other end rotates and slides to the middle under the limiting effect of the positioning groove 73 until the arc-shaped clamping block 72 is clamped on the needle 16, thereby the needle 16 can be stably fixed on the patient, and then the gas in the chest cavity is extracted and discharged by pulling the pulling rod 2, thereby eliminating the need for medical staff to manually fix the needle tube, thereby improving the stability during gas extraction, and preventing it from shaking at will to reduce the effect of gas extraction, and also preventing the patient's internal organs from being harmed. At the same time, the exhaust pipe 1 is separated from the needle 16 and connected with the connecting hose 14, so that the needle 16 will not be shaken due to the action during gas extraction, thereby further improving the stability and safety during exhaust.

[0024] Furthermore, the positioning structure includes a threaded rod 8, which is threadedly mounted on the outer ring 11, and an anti-slip block 81 is installed on the threaded rod 8. A plurality of plug-in grooves 82 are provided on the chassis 9, and the bottom of the threaded rod 8 is plugged into the plug-in groove 82. After the outer ring 11 is rotated to drive the arc-shaped clamping block 72 to clamp on the needle 16 to fix it, the threaded rod 8 is rotated so that its bottom can be plugged into the corresponding plug-in groove 82 to fix the outer ring 11 to prevent the arc-shaped clamping block 72 from loosening when clamped on the needle 16. The anti-slip block 81 can prevent the threaded rod 8 from falling off from the outer ring 11 and being lost when the threaded rod 8 is not in use.

[0025] Furthermore, two retaining rods 17 are installed on the chassis 9, and two arc grooves 18 are opened on the outer ring 11. The two retaining rods 17 are movably installed in the two arc grooves 18 respectively. The retaining rods 17 and the arc grooves 18 can ensure that the outer ring 11 and the chassis 9 always maintain a rotational connection, thereby improving the stability during the connection.

[0026] The working principle is as follows: when puncturing and exhausting the patient, first place the chassis 9 on the part of the patient that needs puncture and fix it with the anti-sensitive glue 13, then pass the needle 16 through the chassis 9 and the inner ring 10 to puncture into the patient's chest cavity. When puncturing to a certain position, rotate the outer ring 11. The rotation of the outer ring 11 drives one end of the rotating rod 7 to move in an arc shape, and the other end rotates and slides to the middle under the limiting effect of the positioning groove 73 until the arc-shaped clamping block 72 is clamped on the needle 16. Then, rotate the threaded rod 8 so that its bottom can be inserted into the corresponding insertion groove 82, fix the outer ring 11, and prevent the arc-shaped clamping block 72 from loosening when clamping on the needle 16. In this way, the needle 16 can be stably fixed on the patient. Then, by pulling the pull-out rod 2, the gas in the chest cavity can be extracted and discharged. Therefore, there is no need for medical staff to manually fix the needle tube, which improves the stability when extracting gas, and will not shake at will to reduce the effect of gas extraction, nor will it hurt the patient's internal organs.
