Abstract

The invention relates to a thoracentesis negative pressure drainage device which belongs to the technical field of medical appliances. The thoracentesis negative pressure drainage device comprises a drainage container, a spring and a drainage tube which are arranged in the container, the drainage container comprises a first spherical cap body and a second spherical cap body, a first spring base isarranged on the inner wall of the first spherical cap body in a protrusive manner, a second spring base is arranged on the inner wall of the second spherical cap body in the protrusive manner, one end of the spring is arranged on the first spring base, the other end is arranged on the second spring base, at least one liquid inlet joint and a row of liquid discharge interfaces are arranged on thefirst spherical cap body, a cover and a tag are connected on the first spherical cap body or the second spherical cap body, and the drainage tube is adapted with the liquid inlet joint. The thoracentesis negative pressure drainage device has the advantages of improving the strength and avoiding the rupture; when in use, the spring can compact or release the whole body, thereby not triggering the phenomena of distortion and bulging; the operation is convenient and the selectivity is good; and the thoracentesis negative pressure drainage device can shorten the drainage time.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment, in particular to a thoracentesis negative pressure drainage device. Background technique

[0002] Thoracentesis negative pressure drainage device has more reports in the literature, especially Chinese patent literature. Drainage tube (patent called drainage device), because the drainage container is a simple wrinkled body structure, it may be difficult to relax (elongate) after being compressed. On the one hand, it will cause inaccurate measurement, especially in the drainage container When it is not full of fluid, it is impossible to confirm the amount of fluid discharged from the pleural cavity; on the other hand, the deformation coefficient is large due to poor strength, which causes confusion in measurement; on the other hand, even for the same patient, the effect of repeated use is poor, because After using for the first time, it is very likely that the wall body of the drainage c...
