This utility model is the problems referred to above that exist clinically at present, and a kind of fixing firm catheter anchoring system is provided, without patient is carried out to sew application, and easy and simple to handle.

Specifically, conduit retainers described in the utility model, comprise the fixedly subsides that can stick on human body skin surface, fixedly stick the ring for fixing that is provided with hollow ring, the inner side of ring for fixing is annular gap, ring for fixing is fastened and forms mutually by upper and lower two parts, lower ring for fixing is fixed on fixedly and sticks, upper ring for fixing can following ring for fixing be that track rotates certain angle on lower ring for fixing, one side bottom of ring for fixing has outlet, in ring for fixing, be provided with for fixing the first coil of drainage tube, the first coil is in ring for fixing, its two ends pass and are fixed on draw ring through outlet.

During use, drainage tube is pasted and ring for fixing through fixing, then will fix and stick on patient body-surface, pull draw ring, draw ring drives First Line circle drainage tube to be fixed on to the inner edge of ring for fixing, again draw ring is fractureed, two the end of a thread that expose the first coil, next rotate upper ring for fixing, drive the second coil to rotate, in the center of ring for fixing, the further bondage of drainage tube is fixed, finally with the two ends of the first coil, drainage tube is strapped in to the exit of ring for fixing, altogether carry out three times and fix, effect is firm.

Further, described conduit ring for fixing also comprises some groups of the second coils, and each second coil is out of shape along ring for fixing, and two ends are separately fixed on ring for fixing and lower ring for fixing, and two fixing points are certain angle between the line at ring for fixing center.

Further, described two fixing points are greater than 180 ° to the angle between the line at ring for fixing center, are less than 360 °.

Further, the number of described the second coil is more than 2 groups.

Further, described draw ring adopts frangible material to make, and the first coil is pulled out and fixed after drainage tube, draw ring can be fractureed, and exposes the two ends of the first coil, then with it, drainage tube is carried out to bondage and fixing in exit.

Further, the bottom surface of described fixedly subsides is stained with the strippable hinge of one deck, has peeled off after hinge, can be by the fixing patient body-surface corresponding site that sticks on.

Conduit retainers described in the utility model, designs ingeniously, easy and simple to handle, without using any apparatus, has also avoided the injury of percutaneous suture to patient simultaneously, can to drainage tube, carry out really effectively fixing, applied widely in simple several steps ground.

The specific embodiment

Below in conjunction with accompanying drawing, technical scheme described in the utility model is described without limitation, object is to understand better described technology contents for the public.

As shown in Fig. 1-6, conduit retainers described in the utility model, comprise the fixedly subsides 1 that can stick on human body skin surface, the bottom surface of fixing subsides 1 is with stickum, can stick and body surface, in the present embodiment, the bottom surface of fixing subsides 1 is also provided with the strippable hinge 10 that one deck plays protective action, peeled off after hinge 10, fixing subsides 1 can have been sticked on to patient body-surface corresponding site.The middle part of fixing subsides 1 is provided with the ring for fixing 2 of hollow ring, ring for fixing 2 fastens mutually by upper and lower two parts the upper ring for fixing 21 and the lower ring for fixing 22 that form and forms, one side of ring for fixing 2 is provided with opening 20, the inner side of ring for fixing 2 is annular gap, lower ring for fixing 22 is fixed on fixing subsides on 1, upper ring for fixing 21 can rotate certain angle for track by following ring for fixing 22 on lower ring for fixing 22, in ring for fixing, be provided with for fixing the first coil 3 of drainage tube 5, the first coil 3 is out of shape in ring for fixing 2, its two ends pass and are fixed on draw ring 4 through exporting 20, described conduit ring for fixing also comprises some groups of the second coils 6, each second coil 6 is out of shape along ring for fixing 2, and two ends are separately fixed on ring for fixing 21 and lower ring for fixing 22, two fixing points are certain angle between the line at ring for fixing 2 centers, conventionally this angle is greater than 180 ° and be less than 360 °, like this in rotation during ring for fixing 21, each second coil 22 will rotate, core at ring for fixing 2 is fixed drainage tube 5 bondages of inserting ring for fixing 2.
