Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 and figure 2 As shown, the novel puncture and drainage device for pleural effusion in this embodiment includes a housing 1 , a movable sleeve 2 , an extraction device 3 , a drainage structure 4 , a piston rod 5 , a roller 7 , a fixed plate 8 and a piston 10 .

[0027] In this embodiment, the housing 1 has a cavity inside and an opening on the left side, that is, it is not closed. The fixing plate 8 is fixed on the inner cavity side wall on the right side of the housing 1 . The right end of the piston rod 5 is fixedly connected with the fixed plate 8; the left end of the piston rod 5 is fixed with a piston 10.

[0028] The movable sleeve 2 is arranged in the cavity of the casing 1, and is sleeved on the piston 10, and is airtightly and slidably connected with the piston 10, that is, the outer diameter of the piston 10...

Abstract

The invention provides a novel pleural effusion puncture drainage device, comprising a housing, a movable sleeve, an extraction device, a drainage structure, a piston rod and a piston. A cavity is arranged inside the housing and an opening is arranged on one side; one end of the piston rod is fixedly connected with the housing, and the left end of the other end of the piston rod is fixedly provided with the piston; the movable sleeve is arranged in the cavity of the housing, and one side of the movable sleeve sleeves the piston, and is slidably connected with the piston in a gas seal manner; the top outer wall of the movable sleeve is provided with the extraction device; the extraction device drives the movable sleeve to move on the piston; and the other side of the movable sleeve is provided with the drainage structure. The advantage is that by pushing the extraction device, the extraction of the effusion can be realized, and the extraction of the pleural effusion can be carried out by a single person, thereby not only improving the working efficiency, but also saving the human resource.

Description

technical field [0001] The invention relates to the technical field of medical internal medicine, in particular to a novel puncture and drainage device for pleural effusion. Background technique [0002] Pleural effusion and pneumothorax are common clinical diseases. In addition to blood and pneumothorax caused by chest trauma and pleural effusion after thoracotomy, in recent years, due to the increasing incidence of lung cancer and tuberculosis, patients with cancerous pleural effusion The number of patients with pleural effusion caused by tuberculosis has increased significantly. In clinical practice, it is often necessary to extract pleural effusion for testing, drainage of pleural effusion, pneumothorax, and hemorrhage. The traditional method is: use a thoracentesis needle, including the needle and the rubber tube at the back end of the thoracentesis, and then connect it to the injection needle after successful puncture. suction. [0003] At present, when patients in i...
