Abstract
Description
Technical Field
[0001] This utility model relates to the field of aspiration device technology, and in particular to a pleural effusion aspiration device for cardiovascular surgery. Background Technology
[0002] Pleural effusion is a common clinical symptom characterized by the pathological accumulation of fluid in the pleural cavity. Pleural effusion may cause chest tightness and difficulty breathing, and may even lead to related complications. Therefore, it is necessary to drain the fluid in a timely manner. As the effusion continues to accumulate, doctors need to repeatedly puncture the effusion site with a disposable syringe. Repeated punctures not only increase the workload of medical staff, but also cause additional pain and harm to the patient.
[0003] For example, the adjustable negative pressure aspirator for pleural effusion disclosed in utility model patent CN221181169U allows for a steady flow of effusion into the collection bottle, thus ensuring a more stable drainage rate for the patient. However, this existing technology has the following problems: changing the effusion collection bottle is cumbersome, and the connection between the puncture needle and the drainage tube is prone to detachment. Utility Model Content

Through the combination of a U-shaped connecting tube, an effusion collection bottle, a U-shaped opening groove, and a disposable drainage tube, the device allows for timely replacement of the empty effusion collection bottle when there is a large amount of effusion. Magnetic suction plates are installed at the bottom of the limiting tray and on the inner side of the base, making it easier for personnel to place the effusion collection bottle inside the limiting tray without causing it to tip over. This also facilitates the movement of the effusion collection bottle by lifting the limiting tray. The combination of a tail plug, a pen-shaped suction head, a top cover, a connector, and an externally threaded tube ensures a more stable installation of the disposable drainage tube and the puncture needle. Furthermore, it allows for smoother puncture and drainage by holding the pen-shaped suction head.
