Catheter fixing device

Abstract

The invention discloses a catheter fixing device. The catheter fixing device comprises an outer catheter, wherein a cavity is formed in the outer catheter, the interior of the cavity is slidably connected with an inner catheter, a drainage cavity is formed in the inner catheter, and a protruding block is arranged at the front end of the inner catheter; a plurality of arc-shaped grooves are formedin the protruding block, and sliding blocks are slidably connected to the interiors of the arc-shaped grooves; one side of each sliding block is fixedly connected with a supporting rod, the side wallof the outer catheter is sleeved with a lantern ring, and one side of the lantern ring is in mesh connection with a fixed ring; a bucket-shaped cavity is formed in the fixed ring, and the side wall ofthe bucket-shaped cavity is movably connected with a plurality of clamping jaws arranged on the lantern ring. The inner catheter can slide in the cavity by rotating a knob so as to drive the protruding block to slide, and the protruding block extrudes the supporting rods into an arc shape, so that each supporting piece arches to form an oval ball body, and the outer catheter and the inner catheter can be firmly fixed in the human body and can not fall outside the human body by using the ball bodies.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheter fixing device. Background technique [0002] At present, in clinical work, indwelling catheters are indispensable for infusion and drainage. Indwelling catheters can not only avoid frequent punctures, but also provide continuous drug drainage. However, there is no ideal way to fix catheters. At present, there are mainly There are the following methods. The venous indwelling needle is mainly pasted with adhesive tape, the closed chest drainage and venous dialysis pipeline are mainly pasted with stitches, and the chest and abdominal drainage tubes are mainly pasted with buckles. Although the above methods can play a role in fixing, the fixed None of them are reliable, and nursing adverse events such as catheter falling off are unavoidable, and the catheter has a large range of motion, which is likely to cause catheter-related bloodstream infection. Therefore, we ...

[0002] At present, in clinical work, indwelling catheters are indispensable for infusion and drainage. Indwelling catheters can not only avoid frequent punctures, but also provide continuous drug drainage. However, there is no ideal way to fix catheters. At present, there are mainly There are the following methods. The venous indwelling needle is mainly pasted with adhesive tape, the closed chest drainage and venous dialysis pipeline are mainly pasted with stitches, and the chest and abdominal drainage tubes are mainly pasted with buckles. Although the above methods can play a role in fixing, the fixed Both are unreliable, and adverse nursing events such as catheter falling off are unavoidable. The catheter has a large range of motion and is likely to cause catheter-related bloodstream infection. Therefore, we propose a catheter fixing device
