Description

Drain irrigation tube with shower head

technical field

The utility model relates to a drainage and flushing tube with a shower head, more particularly to a drainage and flushing tube with a shower head for drainage and flushing, which can be used for drainage/flush after thoracoabdominal surgery, drainage of bladder abscess, and the like.

Background technique

At present, clinically, in the face of patients with diseases such as effusion, exudate, abscess or necrotic tissue infection in the body cavity, the usual method for severe acute pancreatitis with peripancreatic fluid accumulation or peripancreatic abscess is under the guidance of conventional CT or B-ultrasound. First place the irrigation tube for flushing, usually take out the irrigation tube and then place the drainage tube for drainage. At present, double casings are also used for continuous flushing and suction. The inner pipe and the outer pipe are basically straight pipes, and generally the inner pipe extends beyond the outer pipe; there is also a double casing where two pipes are placed in parallel. This type of double cannula cannot be used for directional flushing when flushing, and the flushing area is small and the efficiency is low; and when drainage is performed, the drainage area is small and the drainage effect is poor.
