Abstract
Description
Technical Field
[0001] This utility model relates to the field of assistive medical device technology, and in particular to a catheter-assisted fixation device for interventional therapy. Background Technology
[0002] Catheter fixation devices for interventional procedures are an important piece of equipment in the medical field, designed to improve the precision of interventional procedures and patient comfort. These devices are typically designed to fix and guide catheters during vascular interventional procedures, ensuring the smooth progress of the surgery.
[0003] When using auxiliary fixation devices to fix the catheter, Velcro is mainly used to fix the catheter to the adhesive tape, and then the tape is glued to the skin. Velcro mainly uses friction to fix the catheter. If the catheter is pulled, it will shift within the Velcro, which will make it difficult to perform the interventional treatment normally. Utility Model Content
[0004] This invention addresses the problem that Velcro primarily uses friction to fix catheters, but if the catheter is pulled, it shifts within the Velcro, hindering the normal progress of interventional treatment. Therefore, this invention provides an auxiliary catheter fixation device for interventional treatment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a catheter auxiliary fixing device, comprising an auxiliary strap, an adhesive tape on one side of the auxiliary strap, a hook and loop fastener fixedly connected to the other side of the auxiliary strap, a fixing strap in the middle of the hook and loop fastener, both ends of the fixing strap being fixedly connected to one side of the auxiliary strap, a first hook and loop fastener and a second hook and loop fastener fixedly connected to both sides of the fixing strap, an auxiliary groove on one side of the second hook and loop fastener, auxiliary devices on both sides of the hook and loop fastener, the auxiliary devices comprising two silicone strips symmetrically arranged on both sides of the hook and loop fastener, one side of the silicone strip abutting against one side of the auxiliary strap, two auxiliary blocks on the top of the silicone strips, and clamping blocks symmetrically fixedly connected to the bottom of each of the two auxiliary blocks, the clamping blocks being made of rubber, one side of the clamping blocks abutting against the outer surface of the silicone strips, and a removable device between the silicone strips and the auxiliary strap.
[0006] The effect achieved by the above-mentioned components is as follows: by setting two auxiliary blocks with clamps, the two auxiliary blocks are pushed to slide on the outer surface of the silicone strip until one side of the two auxiliary blocks abuts against the outer surface of the catheter. The friction between the clamps and the silicone strip can fix the auxiliary blocks, thereby assisting in the fixation of the catheter. This can reduce the fixing pressure of the hook and loop fasteners, the first hook and loop fasteners and the second hook and loop fasteners on the catheter, and play an auxiliary role in fixing the catheter. This helps to prevent the catheter from shifting within the fasteners and facilitates the normal progress of interventional treatment.
[0007] Preferably, a magnetic block is fixedly connected to the top of the auxiliary block, and the two magnetic blocks are magnetically attracted to each other.
[0008] The effect achieved by the above components is that by setting two magnetic blocks, they can attract each other when the two auxiliary blocks are close to each other, thereby helping to prevent the clamping of the two auxiliary blocks on the conduit from loosening.
[0009] Preferably, a rubber block is fixedly connected to one side of each of the two auxiliary blocks that are close to each other, and one side of the rubber block is arc-shaped.
[0010] The effect achieved by the above-mentioned components is that by using the curved side of the rubber block to replace one side of the auxiliary block to abut against the outer surface of the pipe, the pipe can be protected, which helps to prevent the auxiliary block from squeezing the pipe excessively and causing the medicine to be unable to flow normally in the pipe.
[0011] Preferably, a slider is fixedly connected to one side of the clamping block, and grooves are symmetrically opened on both sides of the silicone strip, with the outer surface of the slider slidably connected to the inner wall of the groove.
[0012] The effect achieved by the above components is that, by setting the slider and the groove, when the outer surface of the auxiliary block and the silicone strip slides, the slider will move synchronously on the inner wall of the groove, which can limit the position of the auxiliary block.
[0013] Preferably, a stop block is symmetrically fixedly connected to one side of the silicone strip.
[0014] The effect achieved by the above components is that by setting the stop blocks, both ends of the silicone strip can be blocked, which helps to prevent the auxiliary block and clamping block from detaching from the silicone strip due to misoperation.
[0015] Preferably, the easy-to-remove device includes two round hole blocks, one side of each of the two round hole blocks is fixedly connected to both ends of the silicone strip, and a pin is inserted into the inner wall of the round hole block, one end of the pin is fixedly connected to one side of the auxiliary belt.
[0016] The effect achieved by the above components is as follows: by setting a pin, inserting the pin into the inner wall of the round hole block, the silicone strip connected to the round hole block and the auxiliary belt can be connected, and the silicone strip can be detached, so as to facilitate the disassembly, maintenance and replacement of the silicone strip according to actual needs.
[0017] Preferably, one end of the pin is fixedly connected to a locking block, and the cross-section of the locking block is an isosceles trapezoid.
[0018] The effect achieved by the above-mentioned components is as follows: by setting a locking block, one end of the locking block is smaller, making it easier to insert into the inner wall of the round hole block, while the other end of the locking block is larger, which can limit the movement between the round hole block and the pin, thus preventing the pin from easily detaching from the inner wall of the round hole block.
[0019] Preferably, a limiting block is provided on one side of the circular hole block, one side of the limiting block abuts against one side of the circular hole block, and one side of the limiting block is fixedly connected to one side of the auxiliary belt.
[0020] The effect achieved by the above components is that by setting the limiting block, the round hole block can be limited and fixed, further improving the stability of the connection between the silicone strip and the auxiliary belt.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are:
[0022] In this invention, two auxiliary blocks with clamps are provided. The two auxiliary blocks are pushed to slide on the outer surface of the silicone strip until one side of each auxiliary block abuts against the outer surface of the catheter. The friction between the clamps and the silicone strip can fix the auxiliary blocks, thereby assisting in the fixation of the catheter. This reduces the fixing pressure of the hook and loop fasteners, the first hook and loop fasteners and the second hook and loop fasteners on the catheter, and plays an auxiliary role in fixing the catheter. This helps to prevent the catheter from shifting within the fasteners and facilitates the normal progress of interventional treatment. Attached Figure Description

[0028] Example 1, referring to Figures 1-4 As shown, this embodiment discloses a catheter-assisted fixation device for interventional therapy, including an auxiliary strap 1. One side of the auxiliary strap 1 is provided with an adhesive tape 4, and the other side of the auxiliary strap 1 is fixedly connected to a hook-and-loop fastener 5. A fixing strap 6 is provided in the middle of the hook-and-loop fastener 5, and both ends of the fixing strap 6 are fixedly connected to one side of the auxiliary strap 1. A first hook-and-loop fastener 7 and a second hook-and-loop fastener 8 are fixedly connected to both sides of the fixing strap 6. An auxiliary groove 9 is provided on one side of the second hook-and-loop fastener 5. An auxiliary device 2 is provided on both sides of the hook-and-loop fastener 5. The auxiliary device 2 includes two silicone strips 21, which are symmetrically arranged on both sides of the hook-and-loop fastener 5. One side of each silicone strip 21 abuts against one side of the auxiliary strap 1. Two auxiliary blocks 22 are provided on the top of each silicone strip 21. The bottom of each tube is symmetrically fixed with clamping blocks 23. The clamping blocks 23 are made of rubber. One side of the clamping block 23 abuts against the outer surface of the silicone strip 21. A removable device 3 is provided between the silicone strip 21 and the auxiliary band 1. By setting two auxiliary blocks 22 with clamping blocks 23, the two auxiliary blocks 22 are pushed to slide on the outer surface of the silicone strip 21 until one side of the two auxiliary blocks 22 abuts against the outer surface of the catheter. The friction between the clamping block 33 and the silicone strip 21 can fix the auxiliary block 22, thereby assisting in fixing the catheter. This can reduce the fixing pressure of the hook and loop fastener 5, the first hook and loop fastener 7 and the second hook and loop fastener 8 on the catheter, and play an auxiliary fixing role in the catheter. This helps to prevent the tube from shifting again and facilitates the normal progress of interventional treatment.
[0029] Reference Figure 3 and Figure 4 As shown, a magnetic block 24 is fixedly connected to the top of the auxiliary block 22. The two magnetic blocks 24 attract each other magnetically. By setting two magnetic blocks 24, they can attract each other when the two auxiliary blocks 22 are close to each other, which helps to prevent the clamping of the two auxiliary blocks 22 on the conduit from loosening. A rubber block 25 is fixedly connected to the side of the two auxiliary blocks 22 that are close to each other. One side of the rubber block 25 is arc-shaped. By using the arc-shaped side of the rubber block 25 to replace one side of the auxiliary block 22 to abut against the outer surface of the pipe, the pipe can be protected. This helps to prevent the auxiliary blocks 22 from squeezing the pipe excessively, which would prevent the medicine from flowing normally in the pipe.
[0030] Reference Figure 3 and Figure 4 As shown, a slider 26 is fixedly connected to one side of the clamping block 23, and grooves 27 are symmetrically opened on both sides of the silicone strip 21. The outer surface of the slider 26 is slidably connected to the inner wall of the groove 27. By setting the slider 26 and the groove 27, when the outer surfaces of the auxiliary block 22 and the silicone strip 21 slide, the slider will slide synchronously on the inner wall of the groove 27, which can limit the auxiliary block 22. A stop block 28 is symmetrically fixedly connected to one side of the silicone strip 21. By setting the stop block 28, the two ends of the silicone strip 21 can be blocked, which helps to prevent the auxiliary block 22 and the clamping block 23 from disengaging from the silicone strip 21 due to misoperation.
[0031] Reference Figure 3 and Figure 4 As shown, the easy-to-remove device 3 includes two round hole blocks 31. One side of each round hole block 31 is fixedly connected to both ends of the silicone strip 21. A pin 32 is inserted into the inner wall of the round hole block 31. One end of the pin 32 is fixedly connected to one side of the auxiliary belt 1. By setting the pin 32 and inserting it into the inner wall of the round hole block 31, the silicone strip 21 connected to the round hole block 31 can be connected to the auxiliary belt 1. At the same time, the silicone strip 21 can be detached, which facilitates the disassembly, maintenance and replacement of the silicone strip 21 according to actual needs.
[0032] Reference Figure 3 and Figure 4 As shown, a locking block 33 is fixedly connected to one end of the pin 32. The cross-section of the locking block 33 is an isosceles trapezoid. By setting the locking block 33, one end of the locking block 33 is smaller, which makes it easier to insert into the inner wall of the round hole block 31. At the same time, the other end of the locking block 33 is larger, which can limit the movement between the round hole block 31 and the pin 32, which helps to prevent the pin 32 from easily disengaging from the inner wall of the round hole block 31. A limiting block 34 is provided on one side of the round hole block 31. One side of the limiting block 34 abuts against one side of the round hole block 31. One side of the limiting block 34 is fixedly connected to one side of the auxiliary belt 1. By setting the limiting block 34, the round hole block 31 can be limited and fixed, which further improves the stability of the connection between the silicone strip 21 and the auxiliary belt 1.
[0033] Working principle: First, place the pipe on the fixing strap 6, rotate the first hook-and-loop fastener 7 and the second hook-and-loop fastener 8, and pass the first hook-and-loop fastener through the auxiliary groove 9, so that the first hook-and-loop fastener 7 and the second hook-and-loop fastener 8 stick to the loop fastener 5. Then push the two auxiliary blocks 22 to slide on the outer surface of the silicone strip 21, which will drive the slider 26 to slide on the inner wall of the groove 27 until the rubber blocks 25 on one side of the two auxiliary blocks 22 are in contact with the outer surface of the conduit. At this time, the two magnetic blocks 24 attract each other, and there is a large friction between the locking block 33 and the silicone strip 21, which can... The auxiliary block 22 can be fixed, thereby providing auxiliary fixation for the conduit. This reduces the fixing pressure of the hook and loop fastener 5, the first hook and loop fastener 7, and the second hook and loop fastener 8 on the conduit, thus providing auxiliary fixation for the conduit and preventing displacement of the conduit within the fastener. When the silicone strip 21 needs to be installed, the locking block 33 and the pin 32 are inserted into the inner wall of the round hole block 31, and one side of the round hole block 31 abuts against one side of the limiting block 34. Then, the locking block 33 and the limiting block 34 can fix the silicone strip 21 connected to the round hole block 31 and the auxiliary band 1.
