Description of drawings

Referring to the accompanying drawings, the above and other objects, features and advantages of the present invention will be apparent to those skilled in the art from the detailed description of the present invention. the

Figure 1 is a schematic diagram of the double sets of irrigation and drainage tubes in the abdominal cavity with blockage;

FIG. 2 is a schematic structural view of the blockage 16 in FIG. 1 when it is closed. the

Detailed ways

Referring to Fig. 1, the drainage tube of the present utility model is a kind of plugged, replaceable inner tube double-covered peritoneal irrigation drainage tube, mainly comprising: an outer tube 1 and a replaceable inner tube 2 that is easy to insert into the outer tube. The inner tube 2 is inserted into the outer tube from the inner tube insertion cavity 6 of the outer tube 1 to form a double sleeve type. A plurality of flushing holes 3 are arranged at reasonable positions on the front part of the outer tube 1, and they are respectively located at different radial and axial positions of the tube wall at the front part of the outer tube. Several drainage holes 4 are arranged at reasonable positions on the front part of the inner tube 2, and they are respectively located at different radial and axial positions of the tube wall at the front part of the inner tube 2. A flushing liquid injection check valve 8 is installed at the port of the flushing liquid injection cavity 5, and a stopper 16 is connected to the side of the air inlet cavity 7. the

The rear end of the outer tube 1 is provided with three cavities, namely: a flushing fluid injection cavity 5 , an inner tube insertion cavity 6 and an air intake cavity 7 . A flushing liquid injection check valve 8 is installed at the port of the flushing liquid injection cavity 5 . A first connector 111 connected to a negative pressure bottle 13 is inserted into the port of the inner tube insertion cavity 6 and connected through a medical hose 121 . The port of the air inlet cavity 7 is also inserted with a second connector 112 connected to the air sterilizer 14, and is connected by a medical hose 122. the

An outer tapered conduit 15 connected to the flushing liquid bottle 9 is installed on the port of the flushing liquid injection cavity 5 together with the one-way valve 8 . The one-way valve 8 is a plug-in one-way valve. When the outer cone catheter 15 is inserted, the one-way valve 8 is opened, and the one-way valve 8 is opened, so that the flushing liquid injection chamber 5 is connected to the one-way valve 8, and the flushing liquid The flushing fluid or medicine in the bottle 9 enters the flushing area of the patient's abdominal surgery through the outer tube 1. The flushing liquid bottle 9 can be matched with suitable flushing liquid or medicine according to clinical needs. the

A flushing liquid flow regulator 10 is installed between the outer cone conduit 15 and the flushing liquid bottle 9, and the flushing liquid flow regulator 10 can be used for flushing and drainage, or the flushing liquid bottle can be closed for negative pressure drainage. the
