[0004] Although the above patent facilitates medical staff to guide the catheter by means of the provided catheter, front end portion and front guide in cooperation with the supporting guide wire and the loach guide wire, at present, after the intestinal obstruction pipeline enters the patient's intestine, it is necessary to use a fixing patch to fix the intestinal obstruction pipeline on the patient's face. When adjusting the length of the intestinal obstruction pipeline entering the patient's intestine, it is necessary to frequently tear off and stick the fixing patch, which will cause strong discomfort to the patient. Therefore, a one-way sliding fixer for the intestinal obstruction pipeline is needed to solve the above technical problems. Utility Model Content

[0005] The utility model aims to make up for the deficiencies of the prior art and provides a one-way sliding fixer for an intestinal obstruction pipeline.

[0006] To achieve the above object, the utility model provides the following technical solutions: a one-way sliding fixture for an intestinal obstruction pipeline, comprising a fixing patch, the top end of which is fixedly connected to a fixture, both sides of the fixture are provided with perforations, a catheter is provided between the two perforations, and a one-way sliding mechanism is provided inside the fixture;

[0007] The one-way sliding mechanism includes U-shaped blocks arranged at the top and bottom ends of the fixer, the two U-shaped blocks are fixedly connected to springs on the sides away from each other, and the other ends of the springs are fixedly connected to the inner side of the fixer, the inner sides of the U-shaped blocks are rotatably connected to rotating blocks, one side of the rotating blocks is fixedly connected to an arc-shaped clamping block, and the rotating block and the arc-shaped clamping block are an integrated structure.

A rotating shaft is commonly fixedly connected between the two sides inside the fixture, a gear is fixedly connected to the outer side of the rotating shaft, and the gear is respectively meshed with tooth blocks 1 and 2. A through opening is opened at the top of the fixture, and the top of the L-shaped plate 2 is located in the through opening.

[0013] Beneficial effects:

[0014] Compared with the prior art, the one-way sliding fixer for intestinal obstruction pipeline has the following beneficial effects:

[0015] 1. The utility model passes the catheter through one of the perforations, passes between the two rotating blocks, and then passes through the other perforation. Under the tension of the spring, the two rotating blocks and the catheter are squeezed. As the catheter continues to move, the friction generated by the squeezing drives the rotating block to rotate clockwise, and the rotating block drives the arc-shaped clamping block to rotate. Since the outer sides of the rotating block and the arc-shaped clamping block are both curved surfaces, the catheter can slide from between the two rotating blocks and the arc-shaped clamping block to one side of the patient's nostril. When pulled outward, the friction generated by the squeezing drives the rotating block to rotate counterclockwise. When the ends of the two arc-shaped clamping blocks rotate to contact with the catheter, under the action of the spring tension, the two arc-shaped clamping blocks clamp the catheter, so that the catheter cannot be pulled outward and can only slide into the patient's nostrils. Therefore, when the length of the catheter in the patient's intestine needs to be adjusted, the structure does not need to frequently tear off and stick the fixing patch. It only needs to slide the catheter to the patient's nostrils, and the catheter will not be pulled out. This is beneficial to reducing the patient's discomfort and greatly improves practicality.

[0016] 2. The utility model presses L-shaped plate 2 downward through the through hole, and tooth block 2 drives the bottom rotating block and arc-shaped clamping block to move downward, and tooth block 2 drives the gear to rotate, and the gear drives L-shaped plate 1 to move upward, and L-shaped plate 1 drives the top U-shaped block to move upward, and the U-shaped block drives the rotating block and arc-shaped clamping block to move upward, and the top and bottom rotating blocks and arc-shaped clamping blocks are away from each other, and then the catheter is inserted into the fixture through the perforation, and passes through between the top and bottom rotating blocks and arc-shaped clamping blocks, and then passes out from another perforation, and then the wooden stick is released, and under the action of the spring, the top and bottom rotating blocks and arc-shaped clamping blocks are restored to their positions, and then the structure is convenient before installing the catheter, to avoid that the two sets of rotating blocks and arc-shaped clamping blocks close to each other will affect the installation of the catheter.

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 to Figure 5 As shown, a one-way sliding fixture for intestinal obstruction pipeline includes a fixing patch 1, a fixing device 2 is fixedly connected to the top of the fixing patch 1, both sides of the fixing device 2 are provided with perforations 3, and a catheter 4 is provided between the two perforations 3. The catheter 4 is located in the front and rear sides of the tube body inside the fixing device 2, and guide arc plates 9 are provided. Both ends of the guide arc plates 9 are fixedly connected to the inner side of the fixing device 2. The design of the guide arc plates 9 facilitates the guiding installation of the catheter 4. Since the catheter 4 is a flexible tube, it can avoid the catheter 4 from bending during installation. A one-way sliding mechanism 5 is provided inside the fixing device 2;

[0025] The one-way sliding mechanism 5 includes U-shaped blocks 51 disposed at the top and bottom of the inside of the fixture 2. The two U-shaped blocks 51 are fixedly connected to the sides away from each other with springs 52, and the other ends of the springs 52 are fixedly connected to the inside of the fixture 2. The top and bottom ends of the inside of the fixture 2 are fixedly connected to limit rods 7, and the other ends of the limit rods 7 pass through the U-shaped blocks 51. The design of the limit rods 7 limits the movement of the U-shaped blocks 51, so that they can only move longitudinally without skewing. The inside of the U-shaped blocks 51 is rotatably connected to a rotating block 53, and one side of the rotating block 53 is fixedly connected to an arc-shaped clamping block 54, and the rotating block 53 and the arc-shaped clamping block 54 are an integrated structure. A group of friction blocks 10 are fixedly connected to the outer side of the rotating block 53, and a group of friction blocks 2 11 are fixedly connected to the outer side of the arc-shaped clamping block 54. The design of friction blocks 10 and friction blocks 2 11 greatly improves the friction between the catheter 4 and the rotating block 53 and the arc-shaped clamping block 54, ensuring that the sliding of the catheter 4 toward the patient's nostrils can drive the rotating block 53 and the arc-shaped clamping block 54 to rotate.

[0026] During operation, the fixing patch 1 is attached to the patient's face, and then the catheter 4 is passed through one of the perforations 3, passes between the two rotating blocks 53, and then passes through the other perforation 3. At this time, the catheter 4 is inserted into the patient's nostrils. Under the tension of the spring 52, the two rotating blocks 53 and the catheter 4 are squeezed. As the catheter 4 continues to move, the friction force generated by the squeezing drives the rotating block 53 to rotate clockwise, and the rotating block 53 drives the arc-shaped clamping block 54 to rotate. Since the outer sides of the rotating block 53 and the arc-shaped clamping block 54 are both arc surfaces, the catheter 4 can be inserted from between the two rotating blocks 53 and the arc-shaped clamping block 54 to the patient. When the catheter 4 is pulled outward, the friction force generated by the extrusion drives the rotating block 53 to rotate counterclockwise. When the ends of the two arc-shaped clamping blocks 54 rotate to contact the catheter 4, under the action of the tension of the spring 52, the two arc-shaped clamping blocks 54 clamp the catheter 4, so that the catheter 4 cannot be pulled outward and can only slide into the patient's nostrils. Therefore, when the length of the catheter 4 in the patient's intestine needs to be adjusted, there is no need to frequently tear and stick the fixing patch 1. Only the catheter 4 needs to be slid toward the patient's nostrils, and the catheter 4 will not be pulled out, which is conducive to reducing the patient's discomfort and greatly improves practicality.

[0027] An auxiliary mechanism 6 is provided inside the fixture 2, and the auxiliary mechanism 6 includes an L-shaped plate 1 61 fixedly connected to the rear side of the U-shaped block 51 at the top, an L-shaped plate 2 62 fixedly connected to the rear side of the U-shaped block 51 at the bottom, a group of tooth blocks 1 63 fixedly connected to the rear side of the vertical end of the L-shaped plate 1 61, and a group of tooth blocks 2 64 fixedly connected to the front side of the vertical end of the L-shaped plate 2 62. A rotating shaft 65 is commonly fixedly connected between the two sides inside the fixture 2, a gear 66 is fixedly connected to the outer side of the rotating shaft 65, and the gear 66 is respectively meshed with the tooth blocks 1 63 and the tooth blocks 2 64. A through opening 67 is opened at the top end of the fixture 2, and the top end of the L-shaped plate 2 62 is located in the through opening 67. The bottom end inside the fixer 2 is fixedly connected to a limiting rod 8, and the distance between the top end of the limiting rod 8 and the bottom end of the L-shaped plate 62 is smaller than the height of the through-hole 67. The design of the limiting rod 8 prevents the top end of the L-shaped plate 62 from being separated from the through-hole 67, thus playing a limiting role.

[0028] During operation, a wooden stick is taken from the outside, and the L-shaped plate 2 62 is pressed downward through the through hole 67, and the L-shaped plate 2 62 drives the tooth block 2 64 to move downward, and the tooth block 2 64 drives the U-shaped block 51 at the bottom to move downward, so that the rotating block 53 and the arc-shaped clamping block 54 at the bottom move downward. At the same time, the tooth block 2 64 drives the gear 66 to rotate, and the gear 66 drives the tooth block 1 63 to move upward, and the tooth block 1 63 drives the L-shaped plate 1 61 to move upward, and the L-shaped plate 1 61 drives the top U-shaped block 51 to move upward, and the U-shaped block 51 drives the rotating block 53 and The arc-shaped clamp block 54 moves upward, and the top and bottom rotating blocks 53 and the arc-shaped clamp block 54 move away from each other. Then, the catheter 4 is inserted into the fixture 2 through the perforation 3, and passes through between the top and bottom rotating blocks 53 and the arc-shaped clamp block 54, and then passes out from another perforation 3. Then, the wooden stick is released, and under the action of the spring 52, the top and bottom rotating blocks 53 and the arc-shaped clamp block 54 are restored to their positions. This structure is convenient for preventing the two sets of rotating blocks 53 and the arc-shaped clamp block 54 that are close to each other from affecting the installation of the catheter 4 before installing the catheter 4.

[0029] Working principle: stick the fixing patch 1 on the patient's face, then take a wooden stick from the outside, press the L-shaped plate 2 62 downward through the opening 67, the L-shaped plate 2 62 drives the tooth block 2 64 to move downward, the tooth block 2 64 drives the bottom U-shaped block 51 to move downward, so that the bottom rotating block 53 and the arc-shaped clamping block 54 move downward, at the same time, the tooth block 2 64 drives the gear 66 to rotate, the gear 66 drives the tooth block 1 63 to move upward, the tooth block 1 63 drives the L-shaped plate 1 61 to move upward, the L-shaped plate 1 61 drives the top U-shaped block 51 to move upward, the U-shaped block 51 with The movable rotating block 53 and the arc-shaped clamping block 54 are moved upward, and the rotating blocks 53 and the arc-shaped clamping blocks 54 at the top and bottom are moved away from each other, and then the catheter 4 is inserted into the fixture 2 through the perforation 3, and passes through between the rotating blocks 53 and the arc-shaped clamping blocks 54 at the top and bottom, and then passes out from another perforation 3, and then the wooden stick is released. Under the action of the spring 52, the positions of the rotating blocks 53 and the arc-shaped clamping blocks 54 at the top and bottom are restored, and thus this structure is convenient for preventing the two sets of rotating blocks 53 and the arc-shaped clamping blocks 54 that are close to each other from affecting the installation of the catheter 4 before installing the catheter 4.

[0030] Then, the catheter 4 is passed through one of the perforations 3, passes between the two rotating blocks 53, and then passes through the other perforation 3. At this time, the catheter 4 is inserted into the patient's nostril. Under the tension of the spring 52, the two rotating blocks 53 and the catheter 4 are squeezed. As the catheter 4 continues to move, the friction force generated by the squeezing drives the rotating block 53 to rotate clockwise, and the rotating block 53 drives the arc-shaped clamping block 54 to rotate. Since the outer sides of the rotating block 53 and the arc-shaped clamping block 54 are both arc surfaces, the catheter 4 can slide from between the two rotating blocks 53 and the arc-shaped clamping block 54 to one side of the patient's nostril, and When pulled outward, the friction force generated by the extrusion drives the rotating block 53 to rotate counterclockwise. When the ends of the two arc-shaped clamping blocks 54 rotate to contact the catheter 4, under the action of the tension of the spring 52, the two arc-shaped clamping blocks 54 clamp the catheter 4, so that the catheter 4 cannot be pulled outward and can only slide into the patient's nostrils. Therefore, when the length of the catheter 4 in the patient's intestine needs to be adjusted, there is no need to frequently tear and stick the fixing patch 1. Only the catheter 4 needs to be slid toward the patient's nostrils, and the catheter 4 will not be pulled out, which is conducive to reducing the patient's discomfort and greatly improves practicality.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
