Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical auxiliary facilities, and in particular to a peripheral vascular intervention catheter fixing device. Background Art
[0002] The contents of this section merely provide background information related to the present application and may not constitute prior art.
[0003] Peripheral vascular disease, also known as vascular disease, has seen a significant increase in incidence in recent years, with common examples being arteriosclerotic occlusive disease, arteriovenous thrombosis, and aneurysms. Currently, the professional technology for treating peripheral blood vessels is constantly developing, and interventional therapy, as a new treatment method, is becoming increasingly widely used in clinical practice.
[0004] During vascular interventional catheter treatment, part of the catheter needs to be inserted into the patient's body, and part of the catheter is outside the patient's body. The catheter outside the patient's body needs to be fixed accordingly to prevent the catheter from escaping from the patient's body. The current traditional catheter fixing method is to use medical tape to fix the catheter, which has some inconveniences.
[0005] A Chinese patent with authorization announcement number CN216676666U discloses an interventional catheter fixing device, including a fixing belt, two reset mechanisms are fixedly connected to the lower surface of the fixing belt, the bottom end of the reset mechanism is provided with the same placement plate, and a first fixing groove is opened on the lower surface of the fixing belt. By arranging a telescopic rod, a spring, a fixing belt and a placement plate, the catheter is placed on the surface of a second anti-slip pad, and the first strap and the second strap are pulled to complete the fixation of the catheter. When the fixing device needs to be removed, the first strap drives the first pattern sticker to separate from the second Velcro, so that the first anti-slip pad is separated from the catheter, and the catheter is disassembled.
[0006] However, the above-mentioned related technologies have the following defects: in actual use, the patient's body is usually pressed on the first strap and the second strap, which means that when the catheter needs to be removed, the patient's body must be moved, which is more difficult for some postoperative patients. Therefore, the catheter fixing device in the above-mentioned related technologies is more inconvenient to use. Utility Model Content
[0007] In order to solve the above technical problems, the purpose of the present application is to provide a peripheral vascular intervention catheter fixing device, which can facilitate the arrangement and fixation of the extracorporeal part of the peripheral vascular intervention catheter when provided to postoperative patients.
[0008] The purpose of this application is achieved through the following technical solutions:
[0009] A peripheral vascular intervention catheter fixing device includes a mounting portion and a mounting frame arranged on one side of a bed, the mounting frame is arranged on the mounting portion, an arc-shaped clamping plate is slidably arranged on the mounting frame, two arc-shaped clamping plates are provided, and the concave surfaces of the two arc-shaped clamping plates are arranged opposite to each other, an elastic member is arranged on the mounting frame, the elastic member is used to drive the two arc-shaped clamping plates to move in a direction approaching each other, the arc-shaped clamping plate is rotatably connected to the mounting frame, and a limiting member is arranged on the mounting frame, and the limiting member is used to limit the deflection angle of the arc-shaped clamping plate on the mounting frame.
[0010] By adopting the above technical scheme, in actual use, when it is necessary to fix the position of the external catheter, the mounting part is first mounted on one side of the bed, and then the arc-shaped clamp is driven to move in directions away from each other, so that the extracorporeal part of the peripheral vascular intervention catheter is located between the two arc-shaped clamps, and then the two arc-shaped clamps are loosened, and the arc-shaped clamp can move in directions close to each other under the action of the elastic member, thereby completing the clamping of the catheter, and according to the actual situation of the catheter in use, the deflection angle of the arc-shaped clamp on the mounting frame is adjusted, so that the direction of the arc-shaped clamp is basically consistent with the extension direction of the extracorporeal part of the peripheral vascular intervention catheter, avoiding the phenomenon of bending the catheter, and then the deflection angle of the arc-shaped clamp can be limited by using the limiter, so as to avoid the deflection of the arc-shaped clamp during use, resulting in bending of the catheter. Through the above arrangement, no matter where the patient is in which position the interventional catheter treatment is performed, the extracorporeal part of the peripheral vascular intervention catheter can be effectively limited, which is convenient for postoperative patients to use and has good practicality.
[0011] In some possible embodiments, the mounting frame includes a mounting rod and a connecting rod, the mounting rod is horizontally arranged, one end of the connecting rod is fixedly connected to the mounting rod, and the other end is connected to the mounting portion, the mounting rod is hollow, a rotating rod is rotatably inserted in the mounting rod, both ends of the rotating rod extend out of the mounting rod, brackets are fixedly arranged at both ends of the rotating rod, an arc-shaped clamping plate is arranged at one end of the bracket away from the rotating rod, a limit piece is arranged on the mounting rod, and the limit piece is used to limit the deflection angle of the rotating rod on the mounting rod.
[0012] By adopting the above technical solution, when it is necessary to adjust the direction of the arc splint to make it compatible with the extension direction of the external part of the catheter, the limit of the position of the rotating rod in the mounting rod by the limit member is released, and then the rotating rod can be driven to deflect. With the deflection of the rotating rod, the direction of the arc splint can be adjusted. Since the two arc splints are arranged at both ends of the same rotating rod, only the deflection angle of one of them needs to be adjusted, and the deflection angle of the other arc splint is also adjusted synchronously. After the adjustment is completed, the deflection angle of the rotating rod in the mounting rod is limited by the limit member, and the extension direction of the arc splint can be adjusted. The operation is simpler and more convenient, which improves the operating efficiency of the staff.
[0013] In some possible embodiments, the limit member is configured as a pin, and a mounting hole is provided in the connecting rod, one end of the mounting hole is connected to the interior of the mounting rod, the limit member is slidably inserted into the mounting hole, a latch tooth is fixedly provided at one end of the limit member close to the mounting rod, a limit ring is coaxially sleeved on the rotating rod, a slot for the latch tooth to be engaged is provided on the circumference of the limit ring, a plurality of the slots are provided, and the plurality of slots are evenly distributed on the rotating rod along the circumference of the rotating rod, a driving member is provided on the connecting rod, the driving member is fixedly connected to the limit member, and the driving member is used to drive the limit member to move in the mounting hole.
[0014] By adopting the above technical solution, when it is necessary to drive the rotating rod to deflect, the driving member drives the limiting member to move in the installation hole, and the limiting member drives the latching tooth to move in the direction away from the rotating rod, so that the latching tooth disengages from the slot. At this time, the limitation on the deflection angle of the rotating rod is released, and the staff can adjust the rotating rod. By opening multiple slots on the rotating rod, the rotating rod can be fixed in position at more angles, thereby increasing the adjustment range of the direction of the arc splint, so that the overall device can be suitable for more patient scenarios, effectively increasing the scope of application of the device.
[0015] In some possible embodiments, the driving member is configured as a driving block, and a strip hole connected to the mounting hole is opened on the connecting rod along the length direction of the mounting hole, and a connecting block is slidably arranged in the strip hole, one end of the connecting block is fixedly connected to the limiting member, and the other end is fixedly connected to the driving block, and a spring is arranged in the mounting hole, one end of the spring is connected to an end of the limiting member away from the mounting rod, and the other end of the spring is connected to the inner wall of the mounting hole, and the spring is used to drive the limiting member to move in a direction close to the rotating rod.
[0016] By adopting the above technical solution, the limiting member can be driven to move in the mounting hole by pulling the driving member. After the deflection angle of the rotating rod is limited, the limiting member, under the action of the spring, always has a tendency to move in the direction close to the rotating rod, so that the latch tooth is always stuck in the latch groove, which can effectively prevent the latch tooth from being separated from the latch groove due to vibration and the like, resulting in an angular deviation of the rotating rod, thereby improving the reliability of the device during actual use.
[0017] In some possible embodiments, a mounting block is fixedly provided at one end of the bracket away from the rotating rod, a connecting rod is slidably provided in a horizontal direction at one end of the mounting block away from the bracket, an arc-shaped clamping plate is provided at the end of the connecting rod away from the mounting block, and the elastic member is provided in the mounting block, and the elastic member is used to drive the connecting rod to move in a direction away from the mounting block.
[0018] By adopting the above technical solution, in the process of driving the arc-shaped clamping plate to move horizontally, the movement of the arc-shaped clamping plate can drive the connecting rod to move on the mounting block. In this process, the connecting rod guides the movement of the arc-shaped clamping plate, thereby improving the stability of the movement of the arc-shaped clamping plate to a certain extent.
[0019] In some possible embodiments, a slot is provided at one end of the connecting rod away from the mounting block, an insert block is slidably arranged in the slot, the insert block is fixedly connected to the convex surface of the arc-shaped clamping plate, a through hole connected to the slot is provided on the connecting rod, a connecting bolt is slidably inserted in the through hole, and a connecting hole for threaded connection of the connecting bolt is provided on the side wall of the insert block.
[0020] By adopting the above technical solution, the diameter of the peripheral vascular intervention catheter will also change according to different actual application scenarios and different patient medical needs.

Under the joint action of the elastic member, the connecting rod and the sliding rod, the two arc splints can automatically move toward each other, thereby stably clamping the extracorporeal part of the peripheral vascular intervention catheter between the two arc splints. The overall scope of application of the device is further improved, and it can be applied to more patients and more medical scenarios.
[0021] In some possible embodiments, a fixing adhesive is provided on the concave surfaces of the two arc-shaped clamping plates that are close to each other.
[0022] By adopting the above technical solution and setting the fixed adhesive, the fixing effect of the arc splint on the extracorporeal part of the catheter can be effectively improved, and the extracorporeal part of the peripheral vascular intervention catheter can be further prevented from sliding on the arc splint, thereby improving the protection of the patient.
[0023] In some possible embodiments, a slide groove is provided along the length direction of the bed body on a side of the mounting portion away from the bed body, a slider is slidably provided in the slide groove, and the slider is fixedly connected to an end of the connecting rod away from the mounting rod.
[0024] By adopting the above technical solution, the position of the connecting rod is adjusted on the mounting portion according to the different positions of the interventional catheter in the patient's body, so that the device as a whole can be more suitable for actual application scenarios, further improving the scope of application of the device and the practicality during actual use.

The position of the fixing device and the direction of the arc splint can be flexibly adjusted according to the actual needs of the patient to avoid bending the peripheral vascular intervention catheter, which is convenient for postoperative patients to use and has good practicality;
[0027] 2. Two arc-shaped clamping plates are arranged at both ends of the same rotating rod. Only the deflection angle of one of them needs to be adjusted, and the deflection angle of the other arc-shaped clamping plate will be adjusted synchronously. The deflection angle of the rotating rod in the mounting rod is limited by the limiter, and the direction of the arc-shaped clamping plate can be adjusted. The operation is simpler and more convenient, which improves the operating efficiency of the staff;
[0028] 3.

The driving member 55 is used to drive the limiting member 5 to move in the mounting hole 51. As an implementation mode of the present application, the driving member 55 is configured as a driving block.
[0045] When it is necessary to drive the rotating rod 4 to deflect, the driving member 55 drives the limiting member 5 to move in the mounting hole 51, and the limiting member 5 drives the latching tooth 52 to move in the direction away from the rotating rod 4, so that the latching tooth 52 disengages from the latching groove 54.

By providing a plurality of latching grooves 54 on the rotating rod 4, the rotating rod 4 can be fixed at more angles, thereby increasing the adjustment range of the direction of the arc splint 3, so that the device as a whole can be suitable for more patient scenarios, effectively increasing the scope of application of the device.
[0046] Reference Figure 4 A strip hole 56 connected to the mounting hole 51 is opened on the connecting rod 22 along the length direction of the mounting hole 51, and a connecting block 57 is slidably arranged in the strip hole 56.

With the deflection of the rotating rod 4, the direction of the arc splint 3 can be adjusted. Since the two arc splints 3 are arranged at the two ends of the same rotating rod 4, only the deflection angle of one of the arc splints 3 needs to be adjusted, and the deflection angle of the other arc splint 3 will be adjusted synchronously. After the adjustment is completed, the deflection angle of the rotating rod 4 in the mounting rod 21 is limited by the limit member 5, and the adjustment of the direction of the arc splint 3 can be completed.

[0054] The implementation principle of a peripheral vascular intervention catheter fixing device proposed in the embodiment of the present application is:
[0055] In actual use, when it is necessary to fix the position of the peripheral vascular intervention catheter, the mounting portion 11 is first mounted on one side of the bed 1, and then the two arc-shaped splints 3 are driven to move in directions away from each other, so that the extracorporeal part of the peripheral vascular intervention catheter is located between the two arc-shaped splints 3, and then the two arc-shaped splints 3 are loosened, and the arc-shaped splints 3 can move in directions close to each other under the action of the elastic member 63, thereby completing the clamping of the extracorporeal part of the peripheral vascular intervention catheter. According to the actual situation of the catheter in use, the deflection angle of the arc-shaped splint 3 on the mounting frame 2 is adjusted, so that the direction of the arc-shaped splint 3 is basically consistent with the extension direction of the extracorporeal part of the peripheral vascular intervention catheter, avoiding the phenomenon of bending the catheter. After that, the limit member 5 can be used to limit the deflection angle of the arc-shaped splint 3, so as to avoid the deflection of the arc-shaped splint 3 during use, resulting in bending of the catheter. Through the above arrangement, no matter where the patient is in which position the interventional catheter treatment is performed, the extracorporeal part of the peripheral vascular intervention catheter can be effectively limited, which is convenient for the use of postoperative patients and has good practicality.
