[0036] Reference Figure 1 , showing a schematic diagram of a catheter fixing device provided in an embodiment of the present application for fixing a catheter; referring to Figure 2 , showing a top view of a urinary catheter fixing device provided in an embodiment of the present application; referring to Figure 3 , showing one of the side views of a urinary catheter fixing device provided in an embodiment of the present application; referring to Figure 4 , showing a schematic diagram of fixing a rotating part and an adhesive member provided in an embodiment of the present application; referring to Figure 5, showing a second side view of a urinary catheter fixing device provided in an embodiment of the present application; referring to Figure 6 , shows a third side view of a urinary catheter fixing device provided in an embodiment of the present application. Figures 1 to 6 As shown, the catheter fixing device comprises: an adhesive member 10 and a fixing seat 20;

[0037] The adhesive piece 10 has an adhesive surface for being adhered to the patient's body. The fixing seat 20 is rotatably connected to the adhesive piece 10 . The fixing seat 20 has a fixing portion for fixing the urinary catheter 001 .

[0038] In the embodiment of the present application, since the adhesive member has an adhesive surface, the fixing seat 20 is rotatably connected to the adhesive member 10, and the fixing seat 20 has a fixing portion. Therefore, in actual application, when it is necessary to fix the catheter 001 on the patient, the adhesive surface of the adhesive member can be adhered to the patient's body, and then the catheter 001 can be fixed to the fixing portion, so that the fixing seat 20 can be rotatable relative to the adhesive member 10, which can ensure that even if the patient changes his position and moves the catheter 001, the catheter 001 will drive the fixing seat 20 to rotate relative to the adhesive member 10, so that the catheter 001 is always in a relatively straight state, avoiding the problem of the catheter 001 being bent. That is, in the embodiment of the present application, the fixing seat 20 is rotatably connected to the adhesive component, and the fixing portion of the fixing seat 20 can fix the urinary catheter 001. Therefore, in actual application, once the urinary catheter 001 is fixed to the fixing portion, even if the patient changes his position, the fixing seat 20 can be rotatable relative to the adhesive component 10, thereby ensuring that the urinary catheter 001 is always in a relatively straight state, avoiding the urinary catheter 001 from being bent, resulting in the problem of poor drainage of the urinary catheter 001, that is, the urinary catheter 001 can be drained normally when the patient changes his position, thereby improving the patient's comfort.

[0039] In addition, in some embodiments, a fixing buckle 21 is provided on the fixing portion, the fixing buckle 21 is slidably connected to the fixing portion, the fixing seat 20 is movably connected to a fixing cover 23, the fixing buckle 21 is within the covering range of the fixing cover 23, and the fixing buckle 21 is used to support the bifurcation of the catheter 001; when the fixing buckle 23 supports the bifurcation of the catheter 001, the fixing cover 23 is buckled on the fixing seat 20 to press the fixing buckle 21 and the catheter 001 to fix the catheter 001.

[0040] Since the fixing buckle 21 is slidably connected to the fixing part, the fixing buckle 21 can slide relative to the fixing part. Since the fixing seat 20 is movably connected with the fixing cover 23, when it is necessary to fix the urinary catheter 001, the bifurcation of the urinary catheter 001 can be placed on the fixing buckle 21, that is, the bifurcation of the urinary catheter 001 is supported by the fixing buckle 21, and then the fixing cover 23 is covered on the fixing seat 20, and the fixing buckle 21 is within the covering range of the fixing cover 23, so once the fixing cover 23 is covered on the fixing seat 20, the fixing cover 23 can press the fixing buckle 21 and the urinary catheter 001, that is, the fixing cover 23 is connected to the fixing seat 20 by covering the fixing seat 20, so that the fixing cover 23 presses the fixing buckle 21 and the urinary catheter 001 to fix the urinary catheter 001. In addition, since the fixing seat 20 is slidable relative to the fixing part, the position of the fixing buckle 21 relative to the fixing part can be adjusted for catheters 001 of different sizes by sliding the fixing buckle 21, so that the bifurcations of catheters 001 of different sizes can be placed on the fixing buckle 21 and supported by the fixing buckle 21. That is, the fixing buckle 21 is slidably connected to the fixing part, and the fixing seat 20 is movably connected with the fixing cover 23, so that not only can the catheter 001 be fixed, but also the catheter fixing device provided in the embodiment of the present application can fix catheters 001 of different sizes, so that the application range of the catheter fixing device provided in the embodiment of the present application is wider.

[0041] It should be noted that, in the embodiment of the present application, the bifurcation of the catheter 001 is placed at the fixing buckle 21, and then the fixing buckle 21 and the catheter 001 are covered by the fixing cover 23. When the catheter 001 is fixed, the fixing cover 23 will not press the catheter 001 so that the catheter 001 cannot be used for catheterization. That is, even if the fixing cover 23 is covered on the fixing seat 20 to fix the catheter 001, the catheter 001 can still be used for catheterization, and the catheter 001's catheterization performance will not be affected.

[0042] In addition, in the embodiment of the present application, the number of the fixing buckles 21 can be set according to actual needs, for example, the number of the fixing buckles 21 is 1, and for another example, the number of the fixing buckles 21 is 2. The specific number of the fixing buckles 21 is not limited in the embodiment of the present application.

[0043] In addition, in the embodiment of the present application, one end of the fixed cover 23 can be connected to the fixed seat 20 by a hinge, so as to be movably connected to the fixed seat 20. When the urinary catheter 001 needs to be fixed, the other end of the fixed cover 23 can be buckled on the fixed seat 20, so that the portion between the two ends of the fixed cover 23 and the fixed buckle 21 can fix the urinary catheter 001 together to prevent the urinary catheter 001 from being separated from the fixed portion. Among them, the fixed seat 20 is provided with a buckle that can be buckled with the other end of the fixed cover 23. When the fixed cover 23 needs to be covered on the fixed seat 20, by applying force to the other end of the fixed cover 23, the other end of the fixed cover 23 will drive one end of the fixed cover to rotate relative to the fixed seat 20, and the other end of the fixed cover 23 will be close to the fixed seat 20, and buckled with the buckle on the fixed seat 20, so that the fixed cover 23 is buckled on the fixed seat 20. When the fixing cover 23 needs to be separated from the fixing base 20 , the other end of the fixing cover 23 can be separated from the buckle, so that force is applied to the other end of the fixing cover 23 to move it away from the fixing base 20 .

[0044] In addition, in some embodiments, a sliding groove 24 is provided on the fixing portion, and a portion of the fixing buckle 21 is embedded in the sliding groove 24 , and the fixing buckle 21 can slide along the sliding groove 24 .

[0045] Since the fixed part is provided with a sliding groove 24, the fixing buckle 21 is partially embedded in the sliding groove 24, so that the fixing buckle 21 can slide along the sliding groove 24, that is, by providing the sliding groove 24, the fixing buckle 21 can be easily slidably connected to the fixed part.

[0046] In addition, in the embodiment of the present application, blocking parts can be set at both ends of the sliding groove 24, so that when the sliding fixing buckle 21 is slid, the fixing buckle 21 and the blocking part can also clamp a branch of the catheter 001, and then cover the fixing seat 20 through the fixing cover 23 to fix the catheter 001.

[0047] Of course, in the embodiment of the present application, a slide rail can also be provided on the fixing part, and the fixing buckle 21 is partially embedded in the slide rail so that the fixing buckle 21 is slidably connected to the fixing part. The embodiment of the present application does not limit the manner in which the fixing buckle 21 is slidably connected to the fixing part.

[0048] In addition, in the embodiment of the present application, the fixed cover 23 may also be connected to a handle 203 , so that the medical staff can directly open or close the fixed cover 23 by holding the handle 203 .

[0049] In addition, in the embodiment of the present application, a notch is provided on the fixing seat 20, and the sliding buckle 21 is flush with the surface of the fixing seat 20, that is, the sliding buckle 21 is flush with the surface of the sliding groove 24 provided on the fixing seat 20, and the notch is connected to the sliding groove, so that the catheter 001 can be placed in the notch, and the bifurcation of the catheter 001 is located at the sliding buckle 21, and the sliding buckle 21 supports the bifurcation of the catheter 001.

[0050] In addition, in some embodiments, the fixing seat 20 includes a main body 201 and a rotating part 202, the main body 201 is connected to the rotating part 202, a rotating protrusion 101 is provided on the adhesive member 10, and the rotating part 202 is rotatably connected to the rotating protrusion 101; wherein, a fixing part is provided on the main body 201.

[0051] By such a configuration, after the catheter 001 is fixed on the fixing part, once the patient's body position changes, the patient drives the catheter 001 to move, and the catheter 001 will drive the fixing part so that the fixing part drives the body 201 to move, and the body 201 is connected to the rotating part 202, and the rotating part 202 is rotatably connected to the rotating protrusion 101, so that the body 201 will drive the rotating part 202 to rotate relative to the adhesive member 10, thereby avoiding the problem of bending or folding of the catheter 001 when the patient's body position changes. That is, by providing the rotating protrusion 101 on the adhesive member 10, it is convenient to rotate the fixing seat 20 and the adhesive member 10, thereby avoiding the problem of folding of the catheter 001.

[0052] It should be noted that when the fixing seat 20 is provided with a sliding groove 24 , the sliding groove 24 is provided on the main body 201 .

[0053] Of course, in the embodiment of the present application, a rotation hole may be further provided on the adhesive member 10, and a rotation shaft may be provided on the fixing seat 20, and the rotation shaft may be embedded in the rotation hole to realize the rotation connection between the fixing seat 20 and the adhesive member 10. The embodiment of the present application does not limit the specific manner of the rotation connection between the fixing seat 20 and the adhesive member 10.

[0054] In addition, in some embodiments, the rotating portion 202 includes a first sub-clip 2021 and a second sub-clip 2022, and the first sub-clip 2021 and the second sub-clip 2022 are movably connected to enable the rotating portion 202 to have a clamping state and a releasing state, and the first sub-clip 2021 is provided with a first avoidance groove 2023, and the second sub-clip 2022 is provided with a second avoidance groove 2024; when the rotating portion 202 is in the clamping state, the first sub-clip 2021 and the second sub-clip 2022 are movably connected to each other, so that the rotating portion 202 has a clamping state and a releasing state. The rotating protrusion 101 is clamped, and part of the rotating protrusion 101 is located in the first avoidance groove 2023, and part of it is located in the second avoidance groove 2024, and the first sub-clip 2021 and the second sub-clip 2022 are rotatable relative to the rotating protrusion 101; when the rotating part 202 is in a released state, the first sub-clip 2021 and the second sub-clip 2022 release the clamping of the rotating protrusion 101, and the rotating protrusion 101 disengages from the first avoidance groove 2023 and the second avoidance groove 2024.

[0055] Through such a configuration, when the fixed seat 20 needs to be rotationally connected to the adhesive member 10, force can be applied to the first sub-clip 2021 and the second sub-clip 2022 to separate the first sub-clip 2021 and the second sub-clip 2022, and then the first sub-clip 2021 and the second sub-clip 2022 clamp the rotating protrusion 101, and the rotating protrusion 101 is partially located in the first avoidance groove 2023 and partially located in the second avoidance groove 2024, which is equivalent to the first avoidance groove 2023 and the second avoidance groove 2024 surrounding the rotating protrusion 101, and the first sub-frame and the second sub-clip 2022 are rotatable relative to the rotating protrusion 101, so that the fixed seat 20 is rotatable relative to the adhesive member 10, thereby realizing the rotational connection between the fixed seat 20 and the adhesive member 10. When the fixing base 20 needs to be disassembled, the first sub-clip 2021 and the second sub-clip 2022 can release the clamping of the rotating protrusion 101, so that the rotating protrusion 101 is separated from the first avoidance groove 2023 and the second avoidance groove 2024. That is, the rotating portion 202 includes the first sub-clip 2021 and the second sub-clip 2022, which can facilitate the rotational connection between the fixing base 20 and the adhesive member 10 on the one hand, and can also facilitate the disassembly of the fixing base 20 on the other hand, that is, when the fixing base 20 needs to be replaced or moved to another position, the fixing base 20 can be separated from the adhesive member 10.

[0056] It should be noted that in the embodiment of the present application, the first sub-clip 2021 and the second sub-clip 2022 may be connected to a gripping portion 2025 , and the medical staff can apply force to the gripping portion 2025 to move the first sub-clip 2021 and the second sub-clip 2022 away from or closer to each other.

[0057] In addition, in some embodiments, a rotating hole is provided on the rotating portion 202 , and the rotating portion 202 is sleeved on the rotating protrusion 101 through the rotating hole, so that the rotating portion 202 is rotatably connected to the rotating protrusion 101 .

[0058] By providing a rotating hole on the rotating portion 202, when the fixing seat 20 and the adhesive member 10 need to be rotatably connected, the rotating portion 202 can be directly sleeved on the rotating protrusion 101 through the rotating hole, so that the rotating portion 202 can rotate relative to the rotating protrusion 101 to achieve the rotatable connection between the rotating portion 202 and the adhesive member 10. That is, by providing a rotating hole on the rotating portion 202, the fixing seat 20 and the adhesive member 10 can be easily rotatably connected.

[0059] In addition, in some embodiments, the main body 201 and the rotating portion 202 are an integrated structure.

[0060] By configuring the main body 201 and the rotating portion 202 as an integrated structure, the strength of the fixing base 20 can be increased, which is beneficial to improving the strength of the fixing base 20 .

[0061] When processing the fixing seat 20, the fixing seat 20 can be directly injection molded by an injection molding process, so that the body 201 and the rotating part 202 are integrally formed. Of course, the fixing seat 20 can also be directly printed out by a 3D printing process, so that the body 201 and the rotating part 202 are integrally formed. The specific processing technology of the fixing frame is not limited in this embodiment of the application.

[0062] Of course, in the embodiment of the present application, the main body 201 and the rotating part 202 can be two independent components.

[0064] Through such an arrangement, in actual application, the skin-friendly layer 11 can be adhered to the patient's body, and the pressure-reducing layer 12 is stacked with the skin-friendly layer 11, and the fixing seat 20 is rotatably connected to the pressure-reducing layer 12, so that the pressure-reducing layer 12 bears the pressure of the catheter 001, avoiding the problem of causing greater pressure on the patient's body by setting the catheter 001 when the adhesive 10 is attached to the patient's body, and the pressure-reducing layer 12 can have a certain protective effect on the patient's body.

[0065] It should be noted that the material of the skin-friendly layer 11 may be a material that is harmful to human skin. For example, the material of the skin-friendly layer 11 is cotton wool. The specific material of the skin-friendly layer 11 is not limited in the embodiment of the present application.

[0066] In addition, in the embodiment of the present application, the pressure relief layer 12 can be completely embedded in the skin-friendly layer 11 and flush with the surface of the skin-friendly layer 11.

Therefore, in actual application, when it is necessary to fix the catheter 001 on the patient, the adhesive surface of the adhesive member can be adhered to the patient's body, and then the catheter 001 can be fixed to the fixing portion, so that the fixing seat 20 can be rotatable relative to the adhesive member 10, which can ensure that even if the patient changes his position and moves the catheter 001, the catheter 001 will drive the fixing seat 20 to rotate relative to the adhesive member 10, so that the catheter 001 is always in a relatively straight state, avoiding the problem of the catheter 001 being bent. That is, in the embodiment of the present application, the fixing seat 20 is rotatably connected to the adhesive component, and the fixing portion of the fixing seat 20 can fix the urinary catheter 001. Therefore, in actual application, once the urinary catheter 001 is fixed to the fixing portion, even if the patient changes his position, the fixing seat 20 can be rotatable relative to the adhesive component 10, thereby ensuring that the urinary catheter 001 is always in a relatively straight state, avoiding the urinary catheter 001 from being bent, resulting in the problem of poor drainage of the urinary catheter 001, that is, the urinary catheter 001 can be drained normally when the patient changes his position, thereby improving the patient's comfort.
