Problems solved by technology

But the significant shortcoming of this technical scheme is to utilize knotted sutures to bind and fix the catheter. Once the fixation is completed, if you need to loosen and then continue to fix, you need to cut the sutures and must replace the whole device or most of the device. The complexity and difficulty of

Example Embodiment

[0037] Example 1 , See attached Figure 1-9 .

[0038] See attached figure 1 , 4 And 9, the device includes: a skin adhesive layer 1, a fixing body 2, an additional fixing device 3, and a water-absorbing dressing 4.

[0039] See attached figure 2 , The fixed body 2 includes a fixed ring 21 and a rotating ring 22, a hoop 23 and a protective cover 24.

[0040] See attached image 3 , The fixed ring 21 is provided with three static rotating hoop bar pivots 211, a rotating slider track 212 and an elastic lock 213. See attached Image 6 One end of the elastic lock 213 is rotatably connected to the fixed ring through the rotating shaft 2131, the outer operating handle 2132 extends out of the rotating ring, and the internally measured elastic structure 2133 is an arcuate elastic support part that contacts the fixed ring body 21. A plurality of arc-shaped ratchet teeth 2134 arranged in an arc shape are arranged on the outer side of the elastic structure 2133. The static rotation hoop piv...

Example Embodiment

[0053] Example 2, see attached Figure 10-12 .

[0054] The three hoop bars 23 are arranged in a Y shape and inserted into each other, so that the noose is integrated after the three hoop bars are locked to the catheter, which increases the reliability of the fixation.

[0055] In this embodiment, the band strip 23 needs to use a material with strong elastic recovery ability. In the state that the drainage tube is locked by the device, the length of the band is equivalent to the diameter of the fixed ring, and in the released state, the length is equivalent to the length of one side of the equilateral triangle inscribed in the fixed ring.

[0056] In order to make the drainage tube more reliable, a non-slip structure 232 can be provided in the middle of the hoop where the drainage tube is in contact, wherein the non-slip structure 232 can be a non-slip pattern or a non-slip bump.

Abstract

The invention discloses a conduit fixing device and a fixing method. The conduit fixing device comprises a fixing main body, wherein the fixing main body comprises a fixed ring and a rotating ring which are concentric and controllable and are in two-way rotary connection, wherein a non-adhesive side of a skin adhesive layer is fixedly connected with the fixed ring, and an opening is formed in a region, limited by the fixed ring, of the skin adhesive layer; one end of a strake is connected on the fixed ring, and the other end of the strake is connected on the rotating ring; and due to the rigidity of the strake, the own shape of the flexible strake can be maintained under the effect of gravity. The conduit fixing device ensures that a conduit is kept stationary relative to patient skin, so that uncomfortable feeling can be prevented, and conduit falloff or patient pains caused by drawing can be prevented; and conduit fixing can be relieved by simple operation in use, so that water-absorbing dressing can be replaced conveniently.

Description

technical field [0001] The invention relates to the technical field of medical catheter fixation, in particular to a fixing device and a fixing method for fixing a catheter on the skin surface of a patient. Background technique [0002] During treatment, it is common practice to use catheters to directly infuse fluids and medicines into the patient's body, or to guide pus, blood, and fluids accumulated between human tissues or body cavities to the outside of the body. Often, physicians and patients wish to hold catheters in place for extended periods of time during treatment. In order to keep the medical catheter in a proper position during the treatment, there are many ways to fix the catheter on the patient's body. [0003] Common fixation methods include external suture fixation and bandage fixation. In the extracorporeal suture fixation method, the part of the catheter placed outside the body is sutured to the surface of the body with surgical thread, so that the cathe...
