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 stripping the suture without replacing the device will make the device outweigh the benefits compared with manual knotting and fixing
In addition, the use of sutures as fixings is complicated and difficult to assemble during the production process, resulting in low production efficiency and increased production costs

Embodiment 1

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

[0038] See attached figure 1 , 4 and 9, the device comprises: 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 3 static rotating hoop pivots 211 , 1 rotating slider track 212 and an elastic lock 213 . See attached Image 6 , one end of the elastic lock 213 is rotationally connected with the fixed ring through the rotating shaft 2131, and the operating handle 2132 on the outer side protrudes out of the rotating ring, and the inner elastic structure 2133 is an arcuate elastic support part in contact with the fixed ring body 21, A plurality of arc-shaped ratchets 2134 arranged in an arc are arranged on the outer side of the elastic structure 2133 . The static rota...

Embodiment 2

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

[0054] The three hoops 23 are arranged in a Y shape and interspersed with each other, so that the three hoops are locked tightly to the catheter and the noose is integrated to increase the reliability of fixing.

[0055] In this embodiment, the strap 23 needs to use a material with strong elastic recovery ability. In the state of locking the drainage tube of the device, the length of the hoop is equivalent to the diameter of the fixing ring, and in the released state, the length is equivalent to the length of one side of an equilateral triangle inscribed in the fixing ring.

[0056] In order to fix the drainage tube more reliably, an anti-slip structure 232 can be provided at the position where the middle of the hoop contacts the drainage tube, wherein the anti-slip structure 232 can be an anti-slip texture or an anti-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...
