When the catheter is removed, the catheter is pulled to squeeze the bottom inclined surface of the limiting portion 4 until it is deformed, and then separated from the protective sleeve 2, thereby facilitating the installation and disassembly of the catheter.

[0026] Specifically, the protective sleeve 2 is fixed with a perforated plate 5 on both sides, the perforated plate 5 is connected to the surface of the silicone pad 3, the surface of the silicone pad 3 is provided with a fixing part 6 through a connecting rod, the fixing part 6 is elastic, and the fixing part 6 is set to be conical. The perforated plate 5 passes through the fixing part 6 and is sleeved on the surface of the connecting rod, and the bottom of the fixing part 6 is connected to the upper surface of the perforated plate 5.

[0027] In this embodiment, when the protective sleeve 2 is squeezed and deformed or broken, the protective sleeve 2 is pulled in the direction away from the silicone pad 3, so that the protective sleeve 2 drives the side orifice plate 5 to squeeze the bottom of the fixing part 6. The fixing part 6 is made of rubber, so that the fixing part 6 is elastically deformed, and then passes through the fixing part 6 and detaches, so that the protective sleeve 2 can be disassembled, and the protective sleeve 2 can be replaced.

[0028] Specifically, a support plate 7 is fixedly provided at the bottom of the orifice plate 5 . The support plate 7 is arranged in a triangle shape. The support plate 7 is fixedly connected to the side surface of the protective sleeve 2 . The support plate 7 is used to support and reinforce the protective sleeve 2 .

[0029] In this embodiment, the support plate 7 is configured in a triangular shape, and the support plate 7 is disposed between the orifice plate 5 and the protective sleeve 2, and is used to support and reinforce the protective sleeve 2 so that the protective sleeve 2 is not easily deformed.

[0030] Specifically, an anti-slip strip 8 is fixedly provided on the inner side wall of the protective sleeve 2, and a plurality of anti-slip strips 8 are provided in an array. The anti-slip strips 8 are used to increase the friction between the protective sleeve 2 and the catheter.

[0038] The working principle and use process of the utility model are as follows: when the catheter needs to be fixed, the silicone pad 3 drives the protective sleeve 2 to be sleeved onto the catheter, and at the same time the catheter will be squeezed with the top inclined surface of the limiting part 4, so that the catheter enters the protective sleeve 2 after deformation, and then the catheter contacts the bottom inclined surface of the limiting part 4, and the limiting part 4 limits the catheter in the protective sleeve 2; then the fixing patch 1 is fitted with the hook surface 9 at the bottom of the silicone pad 3 through the rough surface 10 on the surface, so that the fixing patch 1 is fixed to the bottom of the silicone pad 3. The fixing patch 1 is a disposable product and can be disassembled after use. Replace it so that the silicone pad 3 can be used multiple times, then tear off the protective film at the bottom of the fixing patch 1, revealing the adhesive surface of the fixing patch 1, and stick the adhesive surface to the patient's skin, so that the catheter is fixed to the patient's skin; when the patient turns over or sits up and changes posture, if the catheter is accidentally pressed, the protective sleeve 2 has hardness, and the protective sleeve 2 on the surface of the catheter can withstand the pressure of the patient's body, avoiding the pressure on the catheter, thereby preventing the catheter from being folded, and at the same time, the silicone pad 3 elastically deforms, and the silicone pad 3 can increase the comfort of the patient when pressing on the protective sleeve 2.

[0039] In summary, the anti-compression-folding catheter fixing device, by providing a protective sleeve 2, has the advantages of being able to withstand the pressure of the body, supporting and protecting the catheter, and preventing the catheter from being crushed. It solves the problem that when the patient changes his posture, the catheter may be pressed under the body, which may easily cause the catheter to be pressed closed, resulting in poor drainage and blockage.
