[0002] Currently, infusion, blood transfusion, drainage and other operations, it is necessary to fix the guide sheath on the skin surface. The traditional fixation method is to fix the guide sheath directly on the skin by wrapping with tape or suturing the skin.

[0003] After searching, a Chinese patent discloses a snap-on catheter fixing patch (Announcement No. CN206745725U). The patented technology fixing patch uses a silicone / rubber belt with a large friction coefficient with a conventional PE catheter for snap-on binding and fixing. The fixing patch not only makes the catheter fixing operation easier, but also has the advantages of being firmly fixed, stable, and not easy to loosen. However, the snap-on binding and fixing method puts a large pressure on the guide sheath tube, which can easily cause deformation and blockage at the fixing point. Therefore, those skilled in the art provide a guide sheath tube fixing device that prevents loosening to solve the problems raised in the above background technology.

[0004] Therefore, a guide sheath fixing device that prevents loosening is proposed to solve the above problem. Utility Model Content

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, a guide sheath tube fixing device for preventing loosening, comprising: a fixing pad, a first adhesive layer is arranged at the bottom of the fixing pad; a fixing structure, the fixing structure is arranged on the surface of the fixing pad, and the fixing structure is used to fix and limit the guide sheath tube; wherein, the fixing structure comprises three straps arranged on the surface of the fixing pad, and the three straps are staggered, wherein two straps on the same side form a first binding portion, and the other strap forms a second binding portion.

[0007] Preferably, three grooves are opened on the top of the fixing pad and are distributed alternately, and the three straps are respectively arranged inside the three grooves, one end of the strap is fixedly connected to the inner wall of the groove, and the other end of the strap passes through the groove.

[0008] Preferably, a second adhesive layer is provided on the top of the binding tape, and a second release paper is provided on the top of the second adhesive layer.

[0009] Preferably, one end of the second release paper away from the fixing pad extends to form a tear-off portion, and the second release paper shields the second adhesive layer.

[0010] Preferably, a first release paper is provided at the bottom of the first adhesive layer, the first release paper covers the first adhesive layer, and a plectrum is fixedly connected to one side of the first release paper.

[0011] Preferably, the surface of the fixing pad is provided with evenly distributed air holes, and the surface of the first adhesive layer is provided with through holes corresponding to the air holes.

[0012] The beneficial effects of the utility model are:

[0013] 1. The setting of the fixing structure can achieve the effect of limiting the guide sheath by taking the binding strap out of the groove, bending it to wrap the guide sheath to be fixed, and then removing the second release paper to make the second adhesive layer fit with the surface of the fixing pad to form a fixing buckle. Since the binding strap itself is relatively soft, it will not generate too much pressure on the guide sheath body during the fixing process, avoiding the situation that the guide sheath is easily deformed due to high pressure during the fixing process of the traditional structure, affecting its use. At the same time, the three staggered binding straps cooperate with each other to effectively improve the effect of limiting the guide sheath.

[0014] 2. By providing ventilation holes and through holes, the ventilation performance during use can be increased, and sweating caused by the heat in the fixed position can be avoided to affect the bonding effect of the first adhesive layer, thereby further improving the overall stability of the structure during use and reducing the possibility of falling off.
