Description

Technical Field

[0001] This utility model relates to a catheter fixing device. Background Technology

[0002] Currently, medical catheters are a widely used medical device. Different catheters have different uses, and catheters usually need to be fixed to the patient during use. For example, a catheter fixing structure for effectively fixing a catheter, disclosed in Chinese Patent No. CN114344671A, can fix the catheter to the patient. In this structure, rotating the locking bolt can move the locking block to press and fix the catheter or loosen it. However, the locking bolt needs to be rotated many times when fixing or loosening the catheter, which takes a long time, resulting in low efficiency in fixing and loosening the catheter and making it inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a catheter fixing device that can quickly fix and loosen catheters, save time in fixing and loosening catheters, improve the speed and efficiency of fixing and loosening catheters, and is more convenient to use.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a catheter fixing device, including a fixing bracket, a locking bolt and a clamping block;

[0005] The locking bolt is slidably mounted on the fixed bracket along its own axial direction and is used to rotate around its own central axis. The locking bolt has a threaded portion.

[0006] The fixed bracket has a clamping part and a deformable part, and the deformable part has a natural state when it is not pressed and a deformed state when it is pressed and deformed.

[0007] The deformable part is provided with a threaded part that is adapted to the screw part. When the deformable part is in its natural state, the screw part and the threaded part are engaged and connected. When the deformable part is in its deformed state, the screw part and the threaded part are disengaged and separated.

[0008] The clamping block is connected to the locking bolt and located on one side of the clamping part, and the guide tube is used to be placed between the clamping part and the clamping block;

[0009] The locking bolt is used to be tightened when the screw part and the threaded part are connected to drive the clamping block to move, thereby causing the clamping block to clamp the conduit on the clamping part. The locking bolt is also used to slide relative to the fixed bracket along its own axis when the screw part and the threaded part are separated.

[0010] Furthermore, the fixed bracket is provided with a first sliding hole and a second sliding hole, the deformable part is located between the first sliding hole and the second sliding hole, and the locking bolt is slidably disposed in the first sliding hole and the second sliding hole along its own axial direction and is used to rotate around its own central axis.

[0011] Furthermore, the deformable part includes a button portion, which is used to deform to the deformed state when the button portion is pressed, thereby disengaging the threaded portion and the screw portion. The deformable part is also used to return to the natural state when the button portion is not pressed, so that the threaded portion and the screw portion can be engaged and connected.

[0012] Furthermore, the clamping block is rotatably connected to the locking bolt;

[0013] The fixed bracket is provided with at least one guide rail groove;

[0014] The clamping block is provided with a guide slider that is adapted to the guide rail groove;

[0015] The guide slider is fitted into the corresponding guide rail groove to limit the rotation angle of the clamp during movement.

[0016] Furthermore, the fixed bracket is also provided with a guide rail protrusion, the extension direction of which is parallel to the extension direction of the guide rail groove;

[0017] The clamping block is connected to a mating block, and the mating block is provided with a mating groove. The mating groove slides with the guide rail protrusion to limit the angle of the clamping block from deflecting during the sliding process.

[0018] The guide slider is located on one end of the clamping block, and the mating block is connected to the other end of the clamping block.

[0019] Furthermore, the locking bolt also has a cap portion connected to the screw portion, and the outer side wall of the cap portion is provided with anti-slip protrusions.

[0020] Furthermore, the clamping part is provided with a fixing groove for placing the catheter, and the clamping block is used to clamp the catheter in the fixing groove on the clamping part.

[0021] Furthermore, the fixing bracket is provided with an opening groove communicating with the fixing groove, and the conduit is used to be inserted into the fixing groove from the opening groove.

[0022] Furthermore, the clamping block is provided with an abutting groove for abutting against the conduit placed in the fixing groove, and at least one of the fixing groove and the abutting groove is provided with anti-slip protrusions.

[0023] Furthermore, a first connecting part for connecting to a strap is connected to one end of the fixing bracket, and a second connecting part for connecting to a strap is connected to the other end of the fixing bracket.

[0024] Using the above technical solution, when it is necessary to clamp and fix the conduit, the conduit is first placed between the clamping part and the clamping block. Then, the deformable part is pressed to deform it, at which point the screw part and the threaded part disengage. Therefore, the locking bolt can be quickly slid towards the clamping part, thereby driving the clamping block to slide quickly towards the clamping part. When the clamping block slides to contact the conduit, the pressed deformable part is released. At this time, the deformable part returns to its natural state, and the screw part engages with the threaded part. Tightening the locking bolt allows the locking bolt to move axially towards the clamping part through the threaded engagement between the screw part and the threaded part, thereby driving the clamping block to move towards the clamping part so that the clamping block clamps the conduit onto the clamping part. When it is necessary to loosen the conduit, press the deformable part to deform it. At this time, the screw part disengages from the threaded part, allowing the locking bolt to slide quickly away from the clamping part. This, in turn, moves the clamping block quickly away from the clamping part, thus loosening the conduit. In summary, when the deformable part is pressed, it is deformed and the screw part disengages from the threaded part. This allows the locking bolt to move quickly along its own axis, which in turn moves the clamping block quickly. Therefore, it is not necessary to tighten the locking bolt when loosening the conduit, while only a few turns are needed when clamping the conduit, saving time. This allows for quick fixing and loosening of the conduit, saving time and improving the speed and efficiency of fixing and loosening the conduit. It is more convenient to use, and the clamping block and the clamping part can clamp and fix conduits of different diameters. Attached Figure Description

[0035] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] Example 1: As Figures 1 to 7 As shown, a catheter fixing device includes a fixing bracket 1, a locking bolt 2, and a clamping block 3;

[0037] The locking bolt 2 is slidably mounted on the fixed bracket 1 along its own axial direction and is used to rotate around its own central axis. The locking bolt 2 has a threaded part 4.

[0038] The fixed bracket 1 has a clamping part 5 and a deformable part 6. The deformable part 6 has a natural state when it is not pressed and a deformed state when it is pressed and deformed.

[0039] The deformable part 6 is provided with a threaded part 7 that is adapted to the screw part 4. When the deformable part 6 is in its natural state, the screw part 4 and the threaded part 7 are engaged and connected. When the deformable part 6 is in its deformed state, the screw part 4 and the threaded part 7 are disengaged and separated.

[0040] The clamping block 3 is connected to the locking bolt 2 and is located on one side of the clamping part 5. The guide tube is used to be placed between the clamping part 5 and the clamping block 3.

[0041] The locking bolt 2 is used to be screwed when the screw part 4 and the threaded part 7 are connected to drive the clamping block 3 to move, thereby causing the clamping block 3 to clamp the conduit on the clamping part 5. The locking bolt 2 is also used to slide relative to the fixed bracket 1 along its own axis when the screw part 4 and the threaded part 7 are separated.

[0042] Specifically, when it is necessary to clamp and fix the conduit, firstly, the conduit is placed between the clamping part 5 and the clamping block 3. Then, the deformable part 6 is pressed to deform it. At this time, the screw part 4 is disengaged from the threaded part 7, so the locking bolt 2 can be quickly slid towards the clamping part 5, thereby driving the clamping block 3 to slide quickly towards the clamping part 5. When the clamping block 3 slides to contact the conduit, the pressed deformable part 6 is released. At this time, the deformable part 6 will return to its natural state, and the screw part 4 will engage with the threaded part 7. Tightening the locking bolt 2 will allow the locking bolt 2 to move axially towards the clamping part 5 through the threaded engagement between the screw part 4 and the threaded part 7, thereby driving the clamping block 3 to move towards the clamping part 5 so that the clamping block 3 clamps the conduit onto the clamping part 5. More specifically, when it is necessary to loosen the conduit, pressing the deformable part 6 causes it to deform, at which point the screw part 4 disengages from the threaded part 7. Therefore, the locking bolt 2 can be quickly slid away from the clamping part 5, thereby causing the clamping block 3 to quickly move away from the clamping part 5, thus loosening the conduit. In summary, when the deformable part 6 is pressed, it is deformed and the screw part 4 disengages from the threaded part 7. This allows the locking bolt 2 to move quickly along its own axial direction, thereby causing the clamping block 3 to move quickly. Therefore, when loosening the conduit, it is not necessary to tighten the locking bolt 2, while when clamping the conduit, only a few turns of the locking bolt 2 are needed, saving time. This allows for quick fixing and loosening of the conduit, saving time and improving the speed and efficiency of fixing and loosening the conduit. It is more convenient to use, and the clamping block 3 and the clamping part 5 can clamp and fix conduits of different diameters.

[0043] like Figures 3 to 5 As shown, the fixed bracket 1 may be provided with a first sliding hole 8 and a second sliding hole 9. The deformable part 6 is located between the first sliding hole 8 and the second sliding hole 9. The locking bolt 2 is slidably disposed in the first sliding hole 8 and the second sliding hole 9 along its own axis and is used to rotate around its own central axis.

[0044] like Figures 3 to 6 As shown, the deformable part 6 has a button part 10. The deformable part 6 is used to deform to the deformed state when the button part 10 is pressed, thereby disengaging the threaded part 7 and the screw part 4. The deformable part 6 is also used to return to the natural state when the button part 10 is not pressed, so that the threaded part 7 and the screw part 4 can be connected. In this embodiment, the deformable part 6 is connected to the fixed bracket 1 by two connecting legs 11.

[0045] like Figure 2 , 3 As shown in Figures 5 and 7, the clamping block 3 is rotatably connected to the locking bolt 2;

[0046] The fixed bracket 1 is provided with at least one guide rail groove 12;

[0047] The clamping block 3 is provided with a guide slider 13 that is adapted to the guide rail groove 12;

[0048] The guide slider 13 is slidably engaged in the corresponding guide rail groove 12 to limit the rotation angle of the clamping block 3 during movement. Specifically, when the deformable part 6 is in its natural state, the screw part 4 and the threaded part 7 are connected. At this time, tightening the locking bolt 2 can drive the clamping block 3 to move towards the clamping part 5. During the movement of the clamping block 3 towards the clamping part 5, since the guide slider 13 is slidably engaged in the guide rail groove 12, the clamping block 3 can be prevented from rotating with the locking nut, thus keeping the angle of the clamping block 3 unchanged during movement. In this embodiment, two guide rail grooves 12 are arranged side by side, and the guide slider 13 corresponds to each guide rail groove 12. The clamping block 3 is rotatably connected to one end of the screw part 4 in the locking bolt 2.

[0049] like Figures 1 to 5 As shown, the locking bolt 2 also has a cap portion 14 connected to the screw portion 4, and the outer side wall of the cap portion 14 is provided with anti-slip protrusions; specifically, by screwing the cap portion 14, the screw portion 4 can be driven to rotate, and the screw portion 4 in the locking bolt 2 is slidably disposed in the first sliding hole 8 and the second sliding hole 9.

[0050] like Figures 3 to 5 As shown, the clamping part 5 may be provided with a fixing groove 15 for placing the catheter, and the clamping block 3 is used to clamp the catheter in the fixing groove 15 on the clamping part 5.

[0051] like Figures 1 to 3As shown, the fixed bracket 1 may be provided with an opening groove 16 communicating with the fixed groove 15, and the conduit is used to be inserted into the fixed groove 15 from the opening groove 16.

[0052] like Figures 1 to 7 As shown, the clamping block 3 is provided with an abutment groove 17 for abutting against the conduit placed in the fixing groove 15. By providing the fixing groove 15 and the abutment groove 17, the conduit can be clamped and fixed more firmly. In this embodiment, both the fixing groove 15 and the abutment groove 17 are provided with anti-slip protrusions 18, which can prevent the conduit from sliding and slipping off. Of course, in some embodiments, the anti-slip protrusions 18 may be provided only on the fixing groove 15 or only on the abutment groove 17.

[0053] like Figures 1 to 5 As shown, a first connecting part 19 for connecting with a strap is connected to one end of the fixation bracket 1, and a second connecting part 20 for connecting with a strap is connected to the other end of the fixation bracket 1. The fixation bracket 1 can be fixed to the patient by the strap.

[0054] like Figure 7 As shown, the clamping block 3 can be rotatably connected to the locking bolt 2 via a quick-connect connection structure. The quick-connect connection mechanism includes a stepped hole 21 in the clamping block 3 and a first connector portion 22 and a second connector portion 23 on the locking bolt 2. The stepped hole 21 has a stepped surface 24, and a slot 25 is provided between the first connector portion 22 and the second connector portion 23. The outer walls of the first connector portion 22 and the second connector portion 23 have radially outward protruding boss portions 26. The first connector portion 22 and the second connector portion 23 are both inserted into the stepped hole 21, and the boss portion 26 abuts against the stepped surface 24.

[0055] Example 2: Figures 6 to 9 As shown, another catheter fixing device includes a fixing bracket 1, a locking bolt 2, and a clamping block 3;

[0056] The locking bolt 2 is slidably mounted on the fixed bracket 1 along its own axial direction and is used to rotate around its own central axis. The locking bolt 2 has a threaded part 4.

[0057] The fixed bracket 1 has a clamping part 5 and a deformable part 6. The deformable part 6 has a natural state when it is not pressed and a deformed state when it is pressed and deformed.

[0058] The deformable part 6 is provided with a threaded part 7 that is adapted to the screw part 4. When the deformable part 6 is in its natural state, the screw part 4 and the threaded part 7 are engaged and connected. When the deformable part 6 is in its deformed state, the screw part 4 and the threaded part 7 are disengaged and separated.

[0059] The clamping block 3 is connected to the locking bolt 2 and located on one side of the clamping part 5, and the guide tube is used to be placed between the clamping part 5 and the clamping block 3;

[0060] The locking bolt 2 is used to be screwed when the screw part 4 and the threaded part 7 are connected to drive the clamping block 3 to move, thereby causing the clamping block 3 to clamp the conduit on the clamping part 5. The locking bolt 2 is also used to slide relative to the fixed bracket 1 along its own axis when the screw part 4 and the threaded part 7 are separated.

[0061] Specifically, when it is necessary to clamp and fix the conduit, firstly, the conduit is placed between the clamping part 5 and the clamping block 3. Then, the deformable part 6 is pressed to deform it. At this time, the screw part 4 is disengaged from the threaded part 7, so the locking bolt 2 can be quickly slid towards the clamping part 5, thereby driving the clamping block 3 to slide quickly towards the clamping part 5. When the clamping block 3 slides to contact the conduit, the pressed deformable part 6 is released. At this time, the deformable part 6 will return to its natural state, and the screw part 4 will engage with the threaded part 7. Tightening the locking bolt 2 will allow the locking bolt 2 to move axially towards the clamping part 5 through the threaded engagement between the screw part 4 and the threaded part 7, thereby driving the clamping block 3 to move towards the clamping part 5 so that the clamping block 3 clamps the conduit onto the clamping part 5. More specifically, when it is necessary to loosen the conduit, pressing the deformable part 6 causes it to deform, at which point the screw part 4 disengages from the threaded part 7. Therefore, the locking bolt 2 can be quickly slid away from the clamping part 5, thereby causing the clamping block 3 to quickly move away from the clamping part 5, thus loosening the conduit. In summary, when the deformable part 6 is pressed, it is deformed and the screw part 4 disengages from the threaded part 7. This allows the locking bolt 2 to move quickly along its own axial direction, thereby causing the clamping block 3 to move quickly. Therefore, when loosening the conduit, it is not necessary to tighten the locking bolt 2, while when clamping the conduit, only a few turns of the locking bolt 2 are needed, saving time. This allows for quick fixing and loosening of the conduit, saving time and improving the speed and efficiency of fixing and loosening the conduit. It is more convenient to use, and the clamping block 3 and the clamping part 5 can clamp and fix conduits of different diameters.

[0062] In this embodiment, the fixed bracket 1 may be provided with a first sliding hole 8 and a second sliding hole 9, the deformable part 6 is located between the first sliding hole 8 and the second sliding hole 9, and the locking bolt 2 is slidably disposed in the first sliding hole 8 and the second sliding hole 9 along its own axial direction and is used to rotate around its own central axis.

[0063] like Figures 6 to 9 As shown, the deformable part 6 has a button part 10. The deformable part 6 is used to deform to the deformed state when the button part 10 is pressed, thereby disengaging the threaded part 7 and the screw part 4. The deformable part 6 is also used to return to the natural state when the button part 10 is not pressed, so that the threaded part 7 and the screw part 4 can be connected. In this embodiment, the deformable part 6 is connected to the fixed bracket 1 by two connecting legs 11.

[0064] like Figures 6 to 9 As shown, the clamping block 3 is rotatably connected to the locking bolt 2. The fixed bracket 1 is provided with at least one guide rail groove 12. The clamping block 3 is provided with a guide slider 13 adapted to the guide rail groove 12. The guide slider 13 is slidably engaged in the corresponding guide rail groove 12 to limit the rotation angle of the clamping block 3 during movement. The fixed bracket 1 is also provided with a guide rail protrusion 27. The extension direction of the guide rail protrusion 27 is parallel to the extension direction of the guide rail groove 12. A mating block 28 is connected to the clamping block 3. The mating block 28 is provided with a mating groove 29. The mating groove 29 is slidably engaged with the guide rail protrusion 27 to limit the angle deflection of the clamping block 3 during sliding. The guide slider 13 is located on one end of the clamping block 3, and the mating block 28 is connected to the other end of the clamping block 3. Specifically, when the deformable part 6 is in its natural state, the screw part 4 and the threaded part 7 are connected. Tightening the locking bolt 2 at this time can move the clamping block 3 towards the clamping part 5. During the movement of the clamping block 3 towards the clamping part 5, the guide slider 13 slides and engages in the guide rail groove 12, and the mating groove 29 slides and engages with the guide rail protrusion 27. This prevents the clamping block 3 from rotating with the locking nut, allowing the clamping block 3 to maintain a constant angle during movement. This ensures that the clamping block 3 will not misalign when clamping and fixing the conduit, thus providing better clamping and fixing of the conduit. In this embodiment, the clamping block 3 is rotatably connected to one end of the screw part 4 in the locking bolt 2.

[0065] like Figures 6 to 9As shown, the locking bolt 2 also has a cap portion 14 connected to the screw portion 4, and the outer side wall of the cap portion 14 is provided with anti-slip protrusions; specifically, by screwing the cap portion 14, the screw portion 4 can be driven to rotate, and the screw portion 4 in the locking bolt 2 is slidably disposed in the first sliding hole 8 and the second sliding hole 9.

[0066] In this embodiment, the clamping part 5 may be provided with a fixing groove 15 for placing the catheter, and the clamping block 3 is used to clamp the catheter in the fixing groove 15 on the clamping part 5.

[0067] In this embodiment, the fixing bracket 1 may be provided with an opening groove 16 communicating with the fixing groove 15, and the conduit is used to be inserted into the fixing groove 15 from the opening groove 16.

[0068] In this embodiment, the clamping block 3 is provided with an abutment groove 17 for abutting against the conduit placed in the fixing groove 15. By providing the fixing groove 15 and the abutment groove 17, the conduit can be clamped and fixed more firmly. In this embodiment, both the fixing groove 15 and the abutment groove 17 are provided with anti-slip protrusions 18, which can prevent the conduit from sliding and slipping off. Of course, in some embodiments, the anti-slip protrusions 18 may be provided only on the fixing groove 15 or only on the abutment groove 17.

[0069] In this embodiment, a first connecting part 19 for connecting with a strap is connected to one end of the fixation bracket 1, and a second connecting part 20 for connecting with a strap is connected to the other end of the fixation bracket 1. The fixation bracket 1 can be fixed to the patient by the strap.

[0070] In this embodiment, the clamping block 3 can be rotatably connected to the locking bolt 2 via a quick-connect connection structure. The quick-connect connection mechanism includes a stepped hole 21 in the clamping block 3 and a first connector portion 22 and a second connector portion 23 on the locking bolt 2. The stepped hole 21 has a stepped surface 24, and a slot 25 is provided between the first connector portion 22 and the second connector portion 23. The outer walls of the first connector portion 22 and the second connector portion 23 have radially outward protruding boss portions 26. The first connector portion 22 and the second connector portion 23 are both inserted into the stepped hole 21, and the boss portion 26 abuts against the stepped surface 24.

[0071] In summary, when it is necessary to clamp and fix the conduit, firstly, the conduit is placed between the clamping part 5 and the clamping block 3. Then, the deformable part 6 is pressed to deform it. At this time, the screw part 4 and the threaded part 7 are disengaged, so the locking bolt 2 can be quickly slid towards the clamping part 5, thereby driving the clamping block 3 to slide quickly towards the clamping part 5. When the clamping block 3 slides to contact the conduit, the pressed deformable part 6 is released. At this time, the deformable part 6 will return to its natural state, and the screw part 4 will engage with the threaded part 7. Tightening the locking bolt 2 will allow the locking bolt 2 to move axially towards the clamping part 5 through the threaded engagement between the screw part 4 and the threaded part 7, thereby driving the clamping block 3 to move towards the clamping part 5 so that the clamping block 3 clamps the conduit onto the clamping part 5. When it is necessary to loosen the conduit, press the deformable part 6 to deform it. At this time, the screw part 4 disengages from the threaded part 7, so the locking bolt 2 can be quickly slid away from the clamping part 5, thereby driving the clamping block 3 away from the clamping part 5, and thus loosening the conduit. In summary, when the deformable part 6 is pressed, it is in a deformed state and the screw part 4 disengages from the threaded part 7. At this time, the locking bolt 2 can move quickly along its own axis, thereby driving the clamping block 3 to move quickly. Therefore, it is not necessary to tighten the locking bolt 2 when loosening the conduit, and only a few turns of the locking bolt 2 are needed when clamping the conduit, saving the time of tightening the locking bolt 2. Therefore, the conduit can be quickly fixed and loosened, saving the time of fixing and loosening the conduit, improving the speed and efficiency of fixing and loosening the conduit, making it more convenient to use, and the clamping block 3 and the clamping part 5 can clamp and fix conduits of different diameters.
