Description

Technical Field

[0001] The invention relates to the technical field of intestinal obstruction catheters, and in particular to an intestinal obstruction catheter anti-blocking device. Background Art

[0002] Intestinal obstruction refers to a disease in which the contents of the intestine cannot be transported and passed through the intestine normally due to various reasons. It is a common surgical disease. The main causes of the disease include postoperative intestinal adhesions, colorectal tumors, intussusception, hernia, intestinal torsion, etc. Obstruction will not only cause anatomical and functional changes in the intestine, but may also lead to systemic physiological disorders, which can be life-threatening in severe cases. There are various types of intestinal obstruction, including mechanical intestinal obstruction, dynamic intestinal obstruction, and vascular intestinal obstruction. The intestinal obstruction catheter is a medical device used to treat intestinal obstruction. It is mainly used for decompression, tension relief, and drainage of intestinal fluid and gas in small intestinal obstruction below the duodenum.

[0003] When in use, the intestinal obstruction catheter is generally inserted through the patient's nasal cavity, and then enters the duodenum through the esophagus and stomach. After confirming the position of the catheter, the doctor will inject a small amount of gas into the other balloon of the intestinal obstruction catheter. After the balloon is expanded, the position of the intestinal obstruction catheter can be relatively fixed to prevent it from falling off or shifting. Since this catheter requires a long retention time, and the catheterization operation is cumbersome and difficult, it requires a high level of technical skills from the operator. Once severe blockage leads to tube removal, it is very difficult to reinsert it. Therefore, in order to ensure the effectiveness of the catheter, it is particularly important to prevent and clear the blockage.

[0004] The traditional practice at present is that medical staff fold and block the end of the catheter close to the wound with one hand, and then use the right hand to gradually squeeze the catheter from the folded and blocked part to the side away from the wound and repeat this process many times to allow the air in the catheter to flow, thereby generating negative pressure in the pipeline, so that minor blockages will be relieved. However, the extrusion force of manual extrusion is difficult to control and is prone to loosening, making the negative pressure effect generated by the extrusion unsatisfactory. In addition, the change of the extrusion direction is not accurate enough, which easily causes excessive concentration of stress in the same extrusion direction, making it difficult for the catheter to return to its original state and resulting in a flat tube wall. This increases the flow resistance of the fluid and deepens the blockage, which is not conducive to the long-term use of intestinal obstruction catheters. Summary of the invention

[0036] Then, after the blocking is completed, the push rod 504 is pushed. A limiting groove 502 is opened on one end surface of the ring body 501, and the inner wall of the limiting groove 502 is slidably connected with the limiting block 503, and the top of the limiting block 503 is fixedly connected with the push rod 504. At the same time, the outer walls of both sides of the push rod 504 are slidably fitted with the inner wall of the slide groove 3, and the outer wall of the support block 505 is slidably fitted with the inner wall of the support groove 4, so that the ring body 501 can be supported by the cooperation of the support block 505 and the support groove 4, and then the ring body 501 can be driven to move by pushing the push rod 504, and then the ring body 501 is driven to move by the ring body 501. The outer wall of the ring body 501 is provided with a spiral groove 506, and through grooves 507 are provided at both end surfaces corresponding to the spiral groove 506, and the inner walls at both ends of the spiral groove 506 are respectively connected to the inner walls of the two through grooves 507, and at the same time, the inner wall of the shell 1 is symmetrically and equidistantly fixedly connected with an auxiliary rod 9, and one end of the auxiliary rod 9 is fixedly connected with a ball 10 corresponding to the spiral groove 506, and the outer wall of the ball 10 is fitted and slid with the inner wall of the spiral groove 506, so that the ring body 501 can rotate during the movement process through the cooperation of the ball 10 and the spiral groove 506;

At the same time, through a plurality of symmetrically arranged auxiliary rods 9, the ring body 501 can continuously perform a cycle of 180 degrees of forward and reverse rotation during the movement.

[0038] Then in this process, a groove 510 is opened at one end of the two movable rods 509 that are far away from each other, and the inner wall of the groove 510 is rotatably connected to the shaft 511, and the outer wall of the shaft 511 is fixedly connected to the roller 512, and at the same time, the outer wall of the roller 512 is squeezed and rolled with the inner wall of the shell 1, and the end of the movable rod 509 that is close to each other is fixedly connected to the connecting frame 513, and the inner wall of the connecting frame 513 is rotatably connected to the roller 514, and at the same time, the outer wall of the roller 514 is fitted and slid with the outer wall of the catheter body 2, so that when the push rod 504 starts to be pushed, first, the two symmetrical rollers 512 are respectively in two symmetrical angles of the inner wall of the shell 1, that is, the farthest distance between the two rollers 512. distance, that is, at this time, the catheter body 2 is in a normal state, and the outer wall of the roller 514 fits with the outer wall of the catheter body 2. When the ring body 501 rotates forty-five degrees, the two rollers 512 will be at the center of the two symmetrical inner walls of the shell 1, that is, the shortest distance between the two rollers 512. At this time, the catheter body 2 is in an extrusion state, and the outer wall of the roller 514 fits with the outer wall of the catheter body 2 for extrusion. When the ring body 501 rotates to ninety degrees, the two rollers 512 will be located again in two symmetrical angles of the inner wall of the shell 1, completing a cycle to achieve continuous switching ninety-degree rotation extrusion, and the extrusion force is stable and accurate, avoiding excessive concentration of stress in the same extrusion direction;

[0039] As described above, when the catheter is unblocked, the push rod 504 can be manually pushed to drive the two symmetrical movable rods 509 to move and rotate, and under the guidance of the square inner wall of the shell 1, a continuous switching 90-degree rotation extrusion is achieved, and the extrusion force is stable and accurate, without the need for manual continuous extrusion, thereby ensuring the negative pressure effect generated by the extrusion in the catheter, which is beneficial to improving the unblocking effect of the catheter, and avoiding excessive concentration of stress in the same extrusion direction, which is beneficial to increasing the service life of the catheter, avoiding the need for repeated catheterization, and facilitating the patient's recovery.

[0040] Embodiment 2: Based on the above embodiment, an extrusion vibration mechanism 6 is provided on the outer wall of the catheter body 2 .

[0041] Further, the extrusion vibration mechanism 6 includes a slide plate 601, and the inner wall of the cavity 515 is symmetrically provided with a limiting groove 602 602, and the outer walls on both sides of the slide plate 601 fit and slide with the inner wall of the limiting groove 602. The top of the slide plate 601 is fixedly connected with an elastic rope 603, and the other end of the elastic rope 603 is movably connected with a rotating column 604, one end of the rotating column 604 is rotatably connected with one end of the shaft 511, and the outer wall of the slide plate 601 on one side facing the through hole 516 is fixedly connected with a connecting block 605, and the other end of the connecting block 605 is fixedly connected with a vibrating block 606, and the side wall where the two vibrating blocks 606 are close to each other fits with the outer wall of the catheter body 2;

[0042] In this embodiment, during the movement and rotation of the movable rod 509, the roller 512 is synchronously driven to roll on the inner wall of the shell 1. At this time, the outer walls on both sides of the slide plate 601 fit and slide with the inner wall of the second limiting groove 602, and the top of the slide plate 601 is hinged with an elastic rope 603, and the other end of the elastic rope 603 is hinged with a rotating column 604, and at the same time, one end of the rotating column 604 is rotatably connected to one end of the shaft rod 511, so that the rotating column 604 can be eccentrically set on the shaft rod 511, so that during the rotation of the shaft rod 511, the slide plate 601 can be driven to rise through the elastic rope 603, and then the outer walls on both sides of the connecting block 1 605 fit and slide with the inner wall of the through hole 516, and the inner wall of the second limiting groove 602 is fixedly connected with a spring 1 607, and the spring 1 The other end of the spring 1 607 is fixedly connected to the top of the slide plate 601, so that when it rises to the maximum distance, as the rotating column 604 moves in a downward circumferential direction, the slide plate 601 can be driven to move downward by the rebound of the spring 1 607 to impact and move beyond the original stop distance, and then the slide plate 601 is fixedly connected to the outer wall of one side of the through hole 516 with the connecting block 1 605, and the other end of the connecting block 1 605 is fixedly connected to the vibrating block 606, and the side wall of the two vibrating blocks 606 that are close to each other fits the outer wall of the catheter body 2, so that the slide plate 601 can drive the vibrating block 606 to collide and impact the outer wall of the catheter body 2, so as to loosen and separate the obstacles adhered to the inner wall of the catheter part, so that the adhered obstacles can be taken away and discharged together with the liquid flowing in the catheter after dredging;

[0043] Furthermore, in a normal state, when the spring 1 607 is in a normal state, the bottom of the vibration block 606 only fits against the outer wall of the catheter body 2. Only in the dredging state, the elastic performance of the spring 1 607 is used to drive the slide plate 601 to move downward a greater distance to achieve the effect of collision impact, so as to facilitate the movement of the device in the ready state, and avoid the vibration block 606 and the outer wall of the catheter body 2 being too tightly fitted to cause damage to the surface of the catheter body 2;

[0044] As described above, when the catheter is being unblocked, the movable rod 509 can be moved and rotated, and the rotation of the roller 512 can be used to drive the two vibration blocks 606 to reciprocate and collide with the surface of the catheter to vibrate, so as to loosen and separate the obstructions adhered to the inner wall of the catheter part, so that after unblocking, the adhered obstructions can be removed together with the liquid flowing in the catheter, thereby achieving a cleaning effect on the inner wall of the catheter, reducing the possibility of clogging of the catheter, and facilitating the prevention of clogging of the catheter.

[0045] Embodiment 3: Based on the above embodiment, an auxiliary clamping mechanism 7 is provided inside the housing 1 .

[0047] In this embodiment, in the process of blocking the catheter, the outer wall of the sliding rod 701 is fitted and slid with the interior of the shell 1, and the sliding rod 701 is fixedly connected with a clamping arc plate 702 at one end facing the catheter body 2, and a groove 2 703 is opened on the top of the sliding rod 701, and at the same time, a spring 2 704 is fixedly connected to the inner wall of the groove 2 703, and the other end of the spring 2 704 is fixedly connected to a trigger block 705, and the inner wall of the groove 3 803 is fitted and slidably connected with a fixed rod 804 corresponding to the trigger block 705, so that during the movement of the two clamping plates 802, the trigger block 705 can be squeezed synchronously by the fixed rod 804, so that the several sliding rods 701 on both sides of the shell 1 are close to each other, so that the catheter is positioned and clamped by the clamping arc plate 702, so that the catheter of this section can be stably located at the center position inside the shell 1, avoiding the position of the catheter being too skewed, and ensuring the squeezing and vibration effect of the movable rod 509 and the vibration block 606 on the catheter;

[0048] Then, in order to prevent the slide bar 701 from affecting the movement of the ring body 501, the top of the trigger block 705 is inclined, and the outer walls on both sides of the push rod 504 are fixedly connected to the trigger rod 706 corresponding to the trigger block 705, and the bottom of the slide bar 701 is fixedly connected to the connecting block 2 707, and at the same time, the outer wall of one side of the connecting block 707 is fixedly connected to the spring 3 708, and the other end of the spring 3 708 is fixedly connected to the outer wall of one side of the shell 1, so that when the ring body 501 approaches the two nearest slide bars 701, the connecting block 2 707 can first touch the inclined surface of the trigger block 705, so that the trigger block 705 shrinks into the groove 2 703, and then the rebound of the spring 3 708 can be used to drive the two slide bars 701 back to their original positions, so as to achieve the effect of releasing the clamping in sequence;

[0049] Then, when the push rod 504 is pushed to the end point, the blocking of the splint 802 is released, and then the push rod 504 can be pulled back to its original position, and then the fixing rod 804 is slidably connected to the trigger block 705 through the inner wall of the groove three 803, and the inner wall of the groove three 803 is fixedly connected to the sliding column 805, and the inside of the fixing rod 804 is slidably connected to the outer wall of the sliding column 805, so that the fixing rods 804 on both sides of the housing 1 can be moved up so that the spring three 708 can drive the sliding rod 701 to completely return to its original position. At this time, the device completes the overall reset, and the above steps can be repeated as needed to perform the next dredging cycle of the catheter body 2;

[0050] As described above, when the catheter is being unblocked, multiple slide bars 701 can be synchronously driven to move in the process of blocking the catheter, so that the catheter can be positioned and clamped by the clamping arc plate 702, so that the catheter of this section can be stably located at the center position inside the shell 1, avoiding the position of the catheter being too skewed, ensuring the squeezing and vibration effect of the movable rod 509 and the vibration block 606 on the catheter, which is beneficial to improving the efficiency of unblocking the catheter.

[0051] Working principle: First, hold the housing 1 with one hand to determine the position on the catheter body 2, and then press the two clamps 802 inward with the other hand at the same time to block the catheter body 2. After the blocking is completed, one hand is released to rotate the two clamping blocks 809 respectively, so that the two clamping blocks 809 are respectively screwed into the clamping grooves 810, and the position of the clamping blocks 809 is fixed by the resilience of the spring 807, so as to free both hands and achieve long-term blocking of the catheter body 2;

[0052] Then push the push rod 504 to drive the ring body 501 to move. First, the two symmetrical rollers 512 are respectively in two symmetrical angles of the inner wall of the shell 1. At this time, the outer wall of the roller 514 fits with the outer wall of the catheter body 2. When the ring body 501 rotates forty-five degrees, the two rollers 512 will be at the center position of the two symmetrical inner walls of the shell 1, which is the shortest distance between the two rollers 512. At this time, the catheter body 2 is in an extrusion state, and the outer wall of the roller 514 fits with the outer wall of the catheter body 2 for extrusion. When the ring body 501 rotates to ninety degrees, the two rollers 512 will be located in the two symmetrical angles of the inner wall of the shell 1 again, completing a cycle to achieve continuous switching ninety-degree rotation extrusion, and the extrusion force is stable and accurate;

[0053] Then, when the roller 512 rolls on the inner wall of the housing 1, the rotating column 604 can be eccentrically arranged on the shaft 511, so that during the rotation of the shaft 511, the slide plate 601 can be driven to rise through the elastic rope 603. When it rises to the maximum distance, as the rotating column 604 moves downward in a circular motion, the slide plate 601 can be driven to move downward by the rebound of the spring 1 607, so that the vibration block 606 collides and impacts the outer wall of the catheter body 2, so as to loosen and separate the obstacles adhered to the inner wall of the catheter part, so that the adhered obstacles can be taken away and discharged together with the liquid flowing in the catheter after dredging;

[0054] Then, in the process of blocking the catheter, the trigger block 705 can be squeezed synchronously through the fixed rod 804, so that the several sliding bars 701 on both sides of the shell 1 are close to each other, and the catheter can be positioned and clamped by using the clamping arc plate 702, so that the section of the catheter can be stably located at the center position inside the shell 1, avoiding the position of the catheter being too skewed. At the same time, when the ring body 501 approaches the two nearest sliding bars 701, the connecting block 2 707 can first touch the inclined surface of the trigger block 705, so that the trigger block 705 shrinks into the groove 2 703, and then the rebound of the spring 3 708 can be used to drive the two sliding bars 701 back to their original positions, thereby achieving the effect of releasing the clamping in turn.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
