[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6The utility model provides a catheter fixing device, comprising a plurality of mounting seats 1, each mounting seat 1 is provided with a guide seat 3 on the front side, and a pair of V-shaped clamping arms 5 are arranged on the guide seat 3 through an adjusting mechanism 4, and the adjusting mechanism 4 is used to drive the two V-shaped clamping arms 5 to move away from or approach each other, and a clamping interval 51 for clamping the catheter and the wire is formed between the two V-shaped clamping arms 5, and the two V-shaped clamping arms 5 have anti-slip patterns, which play an anti-slip and anti-falling effect when clamping the catheter or the guide. A plug block 11 is provided on one side of each mounting seat 1, and a card hole 111 is provided on the plug block 11. A slot 12 for matching and inserting the plug block 11 is provided on the other side of each mounting seat 1, and a guide hole 121 that passes through the slot 12 is provided on the top of each mounting seat 1, and a card rod 122 is slidably inserted in the guide hole 121, and the bottom end of the card rod 122 can extend into the slot 12 and be plugged and matched with the card hole 111, and a fastening mechanism 2 is provided on the rear side of each mounting seat 1, which is used to fix the whole on the bed guardrail.

[0025] When the device is used to restrain and limit the catheter wire, the fastening mechanism 2 is used to fix the device as a whole on the bed guardrail, and then the catheter or guide is placed in the clamping interval 51 between the two V-shaped clamping arms 5, and then the adjustment mechanism 4 is operated to drive the two V-shaped clamping arms 5 to move closer to each other, clamp the catheter or guide and achieve restraint and limitation. In addition, the clamping rod 122 on the first mounting seat 1 is pulled up, and the plug block 11 of the second mounting seat 1 is aligned and inserted into the slot 12 of the first mounting seat 1, and then the clamping rod 122 on the first mounting seat 1 is aligned and inserted into the clamping hole 111 on the plug block 11 of the second mounting seat 1, so that the combined assembly of the two mounting seats 1 can be achieved. By analogy, the relative quantity can be freely combined according to the number of catheters or wires to meet actual usage needs. When disassembling, it is only necessary to pull the clamping rod 122 out of the clamping hole 111. In addition, the two V-shaped clamping arms 5 are driven away from each other by operating the adjustment mechanism 4 to achieve the release of the wire and the catheter.

[0026] The front side of the mounting base 1 is also provided with a label slot 101 for inserting and fixing a label. The label slot 101 is made of transparent acrylic material. The label uses labels with different colors, numbers or / letter combinations to identify different catheters or wires. The label indicates key information such as the name, purpose, and patient information of the catheter. The label material is made of water-resistant and disinfection-resistant material to ensure its durability during cleaning and disinfection.

[0027] Specifically, the top end of each clamping rod 122 extends to the top of the mounting base 1 and is fixed with a pinch handle 123. A spring 124 is sleeved on the outside of each clamping rod 122. One end of the spring 124 is fixed to the lower surface of the pinch handle 123, and the other end is fixed to the top of the mounting base 1. When the pinch handle 123 is pinched to pull the clamping rod 122 upward, the spring 124 is stretched and accumulates force. When the pinch handle 123 is loosened, the elastic force of the spring 124 can drive the clamping rod 122 to automatically reset and insert it into the clamping hole 111. At the same time, the elastic restraint of the spring 124 can prevent the clamping rod 122 from interacting randomly and escaping from the clamping hole 111, thereby ensuring the firmness of the combined assembly connection.

[0028] Specifically, the adjusting mechanism 4 includes a bidirectional threaded rod 41, a pair of nut seats 42 and a twist handle 43. A guide groove 401 is provided on the front side of the guide seat 3. The bidirectional threaded rod 41 is rotatably installed in the guide groove 401. The two nut seats 42 are symmetrically limited and slidably installed in the guide groove 401, and are threadedly matched on both sides of the bidirectional threaded rod 41. The two V-shaped clamping arms 5 are fixed on the two nut seats 42 one by one. One side of the bidirectional threaded rod 41 extends to the side of the guide seat 3 and is fixed with a twist handle 43. The bidirectional threaded rod 41 is rotated forward and reversely by pinching the twist handle 43. The bidirectional threaded rod 41 can drive the two nut seats 42 to move closer to or away from each other in the guide groove 401, and drive the two V-shaped clamping arms 5 to move synchronously, providing drive for the clamping and releasing actions of the two V-shaped clamping arms 5. In addition, by adjusting the spacing between the two V-shaped clamping arms 5 and combining the shapes of the two V-shaped clamping arms 5, it is convenient to clamp catheters and wires of different diameters, and the versatility is high.

[0029] Specifically, a fixing block 6 is fixed to the front side of the mounting seat 1, and a spherical cavity 61 is provided in the fixing block 6 and passes through the front side of the fixing block 6. A ball 62 is rotatably installed in the spherical cavity 61, and a portion of the ball 62 is exposed to the outside. A connecting arm 63 is fixed to the exposed portion of the surface of the ball 62. The guide seat 3 is fixed to the end of the connecting arm 63, and the ball 62 is movably installed in the spherical cavity 61. The guide seat 3 is installed on the ball 62 by using the connecting arm 63, so that there is a ball joint connection effect between the fixing block 6 and the guide seat 3, which makes it easy to adjust the angle of the guide seat 3, so that the nurse can adjust the angle and position of the catheter guide wire according to actual needs.

[0030] Specifically, the side of the guide seat 3 is provided with a second threaded hole 64 that passes through the spherical cavity 61. A fastening screw 65 is screwed on the inner thread of the second threaded hole 64 to match the inner thread. The end of the fastening screw 65 can extend into the spherical cavity 61 and cooperate with the outer wall of the sphere 62. By loosening the fastening screw 65, the fastening of the sphere 62 is cancelled, which facilitates the angle adjustment of the catheter wire. By tightening the fastening screw 65, the end of the fastening screw 65 is pressed against the sphere 62 to achieve the fastening of the sphere 62, which can prevent the sphere 62 from moving at will and help maintain the angle and position of the catheter wire.

[0031] Specifically, the fastening mechanism 2 includes an L-shaped plate 21, a screw 22, a clamping plate 23 and a screwing plate 24. The L-shaped plate 21 is fixed to the rear side of the mounting seat 1. A clamping cavity 211 for accommodating the bed guardrail plate is formed between the L-shaped plate 21 and the mounting seat 1. The L-shaped plate 21 is provided with a first threaded hole 212 with two ends passing through. The screw 22 is threadably installed in the first threaded hole 212. The clamping plate 23 is installed on the end of the screw 22 extending into the clamping cavity 211. The screwing plate 24 is fixed. Fixed on the other end of the screw 22, the structure composed of the mounting seat 1 and the L-shaped plate 21 is clamped on the bed guardrail, and then the screw disk 24 is held to tighten the screw 22. The screw 22 pushes the clamping plate 23 to clamp the guardrail to achieve the fixation of the entire device. When disassembling, only the screw 22 needs to be loosened. In addition, rubber pads are fixed on the clamping surface of the clamping plate 23 and the mounting seat 1 to increase the friction between the guardrail and the guardrail, which has the effect of preventing slippage and falling off, and ensures that the fixation is more firm.
