Description

Technical Field

[0001] This utility model belongs to the field of fixation clip technology, specifically relating to a novel adjustable external fixation clip for intestinal obstruction catheters. Background Technology

[0002] Nasal intestinal obstruction catheter placement is a non-vascular interventional technique performed under endoscopic or X-ray guidance, using a guidewire to insert a nasal intestinal obstruction catheter into the proximal or distal deep small intestine for continuous drainage and decompression. The nasal intestinal obstruction catheter is approximately 3 meters long and, after insertion through the nose, can move with intestinal peristalsis to the distal small intestine, allowing for continuous suction and decompression of the entire small intestine. Especially for patients with low small bowel obstruction, where the drainage effect of a gastric tube is very limited, the intestinal obstruction catheter can easily reach above the obstruction site, effectively suctioning intestinal contents, significantly reducing intestinal pressure, and accelerating the restoration of bowel patency. It is now widely used in clinical practice.

[0003] After placing an indwelling catheter for intestinal obstruction, the length of the catheter from the nasal cavity to the fixation point should be observed multiple times to maintain a certain margin. It is necessary to prevent the catheter from being accidentally pulled out or dislodged, and also to prevent the catheter from being too firmly fixed and affecting its entry into the nasal cavity, making the procedure quite complex. Utility Model Content

[0004] The purpose of this invention is to provide a novel adjustable external fixation clip for intestinal obstruction catheters, which can effectively reduce the occurrence of catheter dislodgement. The fixation point can be adjusted according to the length of the intestinal obstruction catheter's movement into the nasal cavity, making it convenient to use, simple to operate, and reducing the time nurses spend fixing the catheter.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A novel adjustable external fixation clip for intestinal obstruction catheters includes a catheter clamp and an adjusting rope mounted on the catheter clamp. The catheter clamp includes a press-type elastic reset component. The adjusting rope is connected to the press-type elastic reset component, and clamping blocks are fixedly connected to both ends of the press-type elastic reset component.

[0007] Furthermore, anti-slip protrusions are fixedly connected to both sides of the press-type elastic reset component.

[0008] Furthermore, an arc-shaped groove is provided on the side of each of the two clamping blocks that are close to each other.

[0009] Furthermore, multiple small teeth are fixedly connected to the sidewalls of both arc-shaped grooves.

[0010] Furthermore, the adjusting rope includes a tension rope connected to a press-type elastic reset member, and a spring buckle is installed on the outer side of the tension rope.

[0011] Furthermore, the spring buckle includes a hollow shell, with a rope threading opening on the outer side of the hollow shell, through which the elastic rope passes. A return spring is fixedly connected inside the hollow shell, with a clamping plate fixedly connected to one end of the return spring. A pressing block is fixedly connected to the side of the clamping plate away from the return spring. A through hole is opened on the hollow shell, and the pressing block is slidably connected to the outer side of the hollow shell through the through hole.

[0012] Furthermore, an inflatable airbag is fixedly connected to each of the two arc-shaped grooves.

[0013] Furthermore, a pressure regulating mechanism that communicates with the inflatable airbag is fixedly connected to the outside of the clamping block. The pressure regulating mechanism includes an air outlet cylinder fixedly connected to the outside of the clamping block. One end of the air outlet cylinder is connected to the inflatable airbag through a conduit, and the other end of the air outlet cylinder is threadedly connected to a screw. One end of the screw is rotatably connected to a piston located inside the air outlet cylinder, and the piston and the inner wall of the air outlet cylinder are interference-fitted.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example 1

[0025] like Figures 1-3 As shown, a novel adjustable external fixation clip for intestinal obstruction catheters includes a catheter clamp and an adjustment rope mounted on the catheter clamp.

[0026] The catheter clamp is used to hold the catheter on the outside of the intestinal obstruction catheter, thus completing the connection between the clamp and the intestinal obstruction catheter.

[0027] Specifically, such as Figures 1-2 As shown, the catheter clamp includes a press-type elastic reset component 1, an adjusting rope connected to the press-type elastic reset component 1, and clamping blocks 2 fixedly connected to both ends of the press-type elastic reset component 1. The press-type elastic reset component 1 is made of plastic or steel and has a certain elasticity. Initially, it is in a contracted state. Under its own elastic deformation and reset action, the press-type elastic reset component 1 expands outward and applies a force to bring the two clamping blocks 2 closer to each other, so that the two clamping blocks 2 can fit tightly together and clamp the intestinal obstruction catheter placed between the two clamping blocks 2.

[0028] To reduce slippage during installation of the press-type elastic reset component 1, anti-slip protrusions 5 are fixedly connected to both sides of the press-type elastic reset component 1 to improve the anti-slip effect.

[0029] like Figures 1-2 As shown, arc-shaped grooves 6 can be opened on the side of the two clamping blocks 2 that are close to each other. By setting the arc-shaped grooves 6, the gap between the two clamping blocks 2 can be adapted to the intestinal obstruction catheter, reducing the phenomenon of excessive clamping force on the intestinal obstruction catheter and flattening the intestinal obstruction catheter.

[0030] Meanwhile, multiple small teeth 7 can be fixedly connected to the side walls of the two arc-shaped grooves 6. The setting of small teeth 7 can improve the clamping stability of the intestinal obstruction catheter.

[0031] The adjustable cord includes a tension cord 4 connected to the press-type elastic reset component 1. The tension cord 4 can be hung around the patient's neck. A spring buckle 3 is installed on the outside of the tension cord 4. The length can be adjusted according to the patient's neck circumference and the fixation position. After the intestinal obstruction catheter is fixed, it can effectively reduce the phenomenon of catheter dislodgement. The fixation point can be adjusted according to the length of the intestinal obstruction catheter's movement into the nasal cavity. It is convenient to use, simple to operate, reduces the nurse's fixation operation time, and is reusable, reducing consumables.

[0032] Among them, such as Figure 1 and Figure 3 As shown, the structure of the spring buckle 3 is disclosed here. The spring buckle 3 includes a hollow shell 8. A rope-through opening 9 is provided on the outer side of the hollow shell 8. The elastic rope 4 passes through the rope-through opening 9. A return spring 11 is fixedly connected inside the hollow shell 8. A clamping plate 10 is fixedly connected to one end of the return spring 11. Under the elastic thrust of the return spring 11, the clamping plate 10 can clamp and fix the elastic rope 4. A pressing block 12 is fixedly connected to the side of the clamping plate 10 away from the return spring 11. A through hole is provided on the hollow shell 8. The pressing block 12 is slidably connected to the outer side of the hollow shell 8 through the through hole. At this time, the pressing block 12 can be pressed to separate the clamping plate 10 and the elastic rope 4, thereby engaging and locking.

[0033] The working principle of this utility model is as follows:

[0034] After the patient has an indwelling intestinal obstruction catheter inserted through the nose, place the elastic rope with 4 loops around the patient's neck, clamp the catheter clamp onto the intestinal obstruction catheter according to the length of the exposed catheter, and then adjust the position of the spring buckle 3 according to the patient's neck circumference and requirements.

[0035] When the intestinal obstruction catheter is repositioned into the nose and the fixation point needs to be adjusted, the length can be adjusted according to the actual situation.

[0036] Observe the length of the catheter from the nasal cavity to the catheter fixation point multiple times, and maintain a certain margin. Example 2

[0037] The difference between this embodiment and Embodiment 1 is that the small tooth 7 is replaced with an inflatable airbag 14, as detailed below. Figures 4-5 As shown, an inflatable airbag 14 is fixedly connected to each of the two arc-shaped grooves 6. The material of the inflatable airbag 14 is preferably latex. By setting the inflatable airbag 14, a clamping force can be applied more evenly from the periphery of the intestinal obstruction catheter, reducing the deformation of the intestinal obstruction catheter.

[0038] Meanwhile, a pressure regulating mechanism that communicates with the inflatable balloon 14 is fixedly connected to the outside of the clamping block 2. This mechanism is used to adjust the expansion range of the inflatable balloon 14. By adjusting the expansion range of the inflatable balloon 14, the clamping force of the inflatable balloon 14 on the intestinal obstruction catheter can be controlled.

[0039] Specifically, the air pressure regulating mechanism includes an air outlet 15 fixedly connected to the outside of the clamping block 2. One end of the air outlet 15 is connected to the inflatable air bladder 14 through a conduit, and the other end of the air outlet 15 is threadedly connected to a screw 16. One end of the screw 16 is rotatably connected to a piston 17 located inside the air outlet 15. The piston 17 and the inner wall of the air outlet 15 are interference-fitted. At this time, by rotating the screw 16 to adjust the position of the piston 17, the amount of gas inside the inflatable air bladder 14 can be adjusted.

[0040] Meanwhile, a groove 13 can be provided on the arc-shaped groove 6, and the inflatable airbag 14 is adhered to the inner wall of the groove 13. Through the setting of the groove 13, the inflatable airbag 14 can be completely contracted inside the groove 13.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
