Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical auxiliary equipment, in particular to a catheter anti-drop structure for intravenous treatment. Background Art
[0002] Intravenous therapy is a medical technique that administers fluids, medications, and nutrients directly into the human vein. This route of administration is often used to rehydrate or provide nutrition to individuals who are unable or unwilling to consume food or water orally due to a decreased mental state or other reasons. It can also be used to administer medications or other medical therapies. Intravenous therapy requires the use of an infusion catheter. To prevent the catheter from sliding or falling out during intravenous therapy, a retaining mechanism is used to secure it.
[0003] However, existing anti-dropout structures often use adhesive tape to adhere the catheter to the body. This method can squeeze the catheter, potentially affecting the flow of fluid within the catheter. Furthermore, when the tape is removed, it pulls on the skin, making it inconvenient to prevent the catheter from dropping out and making it impossible to reuse. Furthermore, these anti-dropout structures lack the ability to quickly remove or tighten the tape, making it impossible to adjust the strap to the user's physical condition. Therefore, we provide an anti-dropout structure for intravenous therapy catheters to address these issues. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1
[0028] See also Figures 1 to 6The present invention is a catheter anti-dropout structure for intravenous treatment. By removing the U-shaped sleeve 2 from the insertion port 105, the catheter can be easily moved in or out of the U-shaped sleeve 2, thereby preventing the catheter from dropping out. At the same time, the elastic buckle plate 4 is used in conjunction with the toothed belt 301 to facilitate quick disassembly or loosening of the strap 3.
[0029] Specifically, the connecting plate 1; a strap 3 is provided directly below the connecting plate 1, one end of the strap 3 is fixed with a square frame 302, and the other end is fixed with a toothed belt 301, and the inside of the square frame 302 is provided with an elastic buckle plate 4 which is inclined in the upper left and lower right shape, and the left and right ends of the connecting plate 1 are fixed with a sleeve rod 104, and the two ends of the elastic buckle plate 4 pass around the upper side of the sleeve rod 104, and a U-shaped sleeve 2 is provided in the middle position of the upper side of the connecting plate 1, and the upper end face of the connecting plate 1 is fixed with an abutment block 101, and the upper end face of the connecting plate 1 on the left side of the abutment block 101 is provided with an insertion port 105 which is symmetrically arranged therewith, and the right end portion of the U-shaped sleeve 2 abuts against the abutment block 101, and the other left end portion is arranged in the insertion port 105.
[0030] The operation process of this embodiment is as follows: through the use of the above-mentioned structure, when the catheter needs to be positioned, the U-shaped sleeve 2 is moved upward on the upper end of the connecting plate 1, so that one end of the U-shaped sleeve 2 is disengaged from the internal position of the plug-in port 105. At this time, the catheter is slid along the peripheral side of the connecting plate 1 to the position between the plug-in port 105 and the abutment block 101, the U-shaped sleeve 2 is loosened, and then one end of the U-shaped sleeve 2 is reinserted into the plug-in port 105, thereby limiting the catheter and achieving the anti-slip effect. At the same time, when the strap 3 is disassembled, the elastic buckle is controlled The plate 4 rotates so that the end of the elastic buckle plate 4 disengages from the tooth mouth position of the toothed belt 301, and then the toothed belt 301 can be taken out from the inside of the square frame 302, and the square frame 302 is pulled out, so that the toothed belt 301 is pulled out from the peripheral position of the two sleeve rods 104, and the strap 3 can be disassembled. At the same time, the toothed belt 301 is moved inside the square frame 302, and the elastic buckle plate 4 is stuck in the tooth mouth position of the toothed belt 301, so that the elastic buckle plate 4 will limit the toothed belt 301 in the square frame 302, and the toothed belt 301 can be pulled to tighten or loosen the strap 3.
[0031] Example 2
[0032] See also Figure 4 、 Figure 5 and Figure 6 On the basis of Example 1, the use of spring 2 402 makes it easier for the elastic buckle plate 4 to re-lock the toothed belt 301.
[0033] Specifically, one end of the toothed belt 301 passes through the internal position of the square frame 302, and the lower right part of the elastic buckle plate 4 is stuck in the tooth position of the toothed belt 301. The elastic buckle plate 4 is fixed with a spring 2 402 connected to the inside of the square frame 302 on the end face opposite to the toothed belt 301. The front and back faces of the upper left end of the elastic buckle plate 4 are fixed with a rotating rod 401. The front and back ends of the frame 302 are provided with a rotating hole 304 at the position corresponding to the rotating rod 401. The rotating rod 401 rotates in the internal position of the rotating hole 304. The front and back ends of the frame 302 are provided with an arc opening 303 with the rotating hole 304 as the center of the circle. The front and back ends of the elastic buckle plate 4 are fixed with a shaft rod 404 sliding in the internal position of the arc opening 303. One end of the shaft rod 404 passing through the inside of the arc opening 303 is fixed with an adjustment block 403 connected to the side of the frame 302.
[0034] The operation process of this embodiment is as follows: when the elastic buckle plate 4 is rotated, the elastic buckle plate 4 drives the rotating rod 401 to rotate inside the rotating hole 304, and the elastic buckle plate 4 will slide the shaft 404 inside the arc opening 303. At the same time, after the adjustment block 403 is used to drive the elastic buckle plate 4 to rotate, the elastic buckle plate 4 will compress the spring 2 402. Therefore, when the adjustment block 403 is loosened, the spring 2 402 will push the elastic buckle plate 4 to reset and rotate, so that it can re-engage with the toothed belt 301.
[0035] Example 3
[0036] See also Figure 1 、 Figure 2 and Figure 3 On the basis of Example 1, the U-shaped sleeve 2 can be stably plugged into the plug port 105 by pushing the round block 203 by the spring 1 202 .
[0037] Specifically, two front-to-back symmetrical limiting holes 103 are provided on the upper end surface of the abutment block 101, and movable holes 102 are provided at the bottom ends of the limiting holes 103, and the movable holes 102 are larger than the aperture of the limiting holes 103. A moving rod 201 is fixed at the position of the lower end surface of the U-shaped sleeve 2 corresponding to the limiting holes 103, and the end of the moving rod 201 passing through the limiting holes 103 is fixed with a round block 203 that slides in the position inside the movable hole 102. The upper end surface of the round block 203 is fixed with a spring 202 that is sleeved on the circumferential side of the moving rod 201, and the upper end surface of the spring 202 abuts against the top surface of the movable hole 102.
[0038] The operation process of this embodiment is as follows: when the U-shaped sleeve 2 is moved upward, the U-shaped sleeve 2 will drive the moving rod 201 to slide inside the limiting hole 103, and the moving rod 201 will drive the round block 203 to move inside the movable hole 102, and the round block 203 will compress the spring 1 202. At the same time, after the U-shaped sleeve 2 is loosened, the spring 1 202 will push the round block 203 to move downward stably, so that one end of the U-shaped sleeve 2 is stably inserted into the plug interface 105.
