[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, since the third fixing block is shorter, that is, the corresponding clamping plate of the third fixing block is farther away from the main body of the drainage catheter. Therefore, when the second slider drives the clamping plate to slide and press the outer wall of the main body of the drainage catheter, the main body of the drainage catheter will be pressed and bent for a certain distance before the outer wall of the main body of the drainage catheter can be abutted against the corresponding clamping plate of the third fixing block, so as to obtain a supporting force. At this time, the pressed end of the main body of the drainage catheter is bent towards the direction close to the third fixing block. During the bending process, pressing can cause the inner cross-section of this section of the main body of the drainage catheter to be squeezed and deformed to become narrower. At this time, pressing the main body of the drainage catheter will cause the deformation to promote the liquid in the main body of the drainage catheter to flow through the narrowed section of the main body of the drainage catheter, making the flow rate of this section of the main body of the drainage catheter larger, better clearing blockages, and washing away thrombus or other coagulated substances in the drainage catheter by a greater pressure of the fluid. Moreover, the process of the main body of the drainage catheter returning to its original position after being pressed and bent is also beneficial to preventing blockages in the main body of the drainage catheter.

[0016] In the present invention, since the second fixing block is shorter, the fifth slider will drive the corresponding clamping plate to first press and bend the main body of the drainage catheter before it can be abutted against the corresponding clamping plate of the second fixing block to clamp the main body of the drainage catheter. And at this time, the bending direction of this section of the main body of the drainage catheter is opposite to the previous bending direction, which can better and more evenly prevent blockages of the main body of the drainage catheter.

[0017] In the present invention, when the output end of the electric telescopic rod extends and drives the first fixing block to move, the movement of the first fixing block will drive the support frame to move synchronously. During the movement of the support frame, the first ball on its outer wall will abut against the inside of the spiral groove. Since the support frame cannot rotate, this abutment will cause the rotating ring to drive the spiral groove to rotate along the outer wall of the moving plate. The rotation of the rotating ring will drive the two dial plates at its end to rotate synchronously. The rotation of the two dial plates will twist the main body of the drainage catheter between the two dial plates, so that this section of the main body of the drainage catheter cannot continue to flow after being torsionally deformed. When the first ball moves to the end of the spiral groove, at this time, as the first fixing block and the first guide rod continue to move, the latter section of the main body of the drainage catheter will start to be bent and squeezed. And at this time, the moving plate will stretch the first spring under force and slide along the outer wall of the first guide rod to prevent jamming. Description of the Drawings

[0022] In this embodiment: Currently, in clinical practice, medical adhesive tape and an auxiliary abdominal belt are basically used to fix the drainage catheter. Due to the insufficient bundling strength of the adhesive tape and the auxiliary abdominal belt or the patient's allergy to the adhesive tape, the drainage tube may be displaced or fall off; once it falls off, it belongs to a serious adverse event. Sutures are required to fix the drainage catheter to the skin, and the sutures need to be removed when the tube is removed, causing pain to the patient.

[0023] The traditional fixing method is likely to cause the drainage catheter to be folded, twisted, and blocked, seriously affecting the drainage effect and the patient's recovery; During the use of the device, first put the elastic abdominal belt main body 91 on the patient's abdomen. The good resilience of the elastic abdominal belt main body 91 can closely adhere to the patient's abdomen. Then, insert one end of the drainage catheter main body 5 into the limit groove 801, and then pull the end of the drainage catheter main body 5 from outside the limit groove 801 and insert it into the through groove 701. Finally, insert it out from the hole outside the second fixing frame 7. Finally, dock the end of the drainage catheter main body 5 with the port of the drainage bag. Then, start the electric telescopic rod 10. After the electric telescopic rod 10 is started, it drives the first fixing block 11 at the output end to move away from the electric telescopic rod 10. When the first fixing block 11 moves, it drives the first guide rod 21 and the second spring 22 to move synchronously. At this time, the second spring 22 pushes the first slider 23 to move synchronously. During the movement of the first slider 23, the rack 24 on its outer wall will move synchronously. The movement of the rack 24 will mesh with the first gear 25. The elastic force of the second spring 22 is relatively large, which can support the smooth meshing of the first gear 25 and the rack 24. When the first gear 25 is meshed, it will rotate counterclockwise. The first gear 25 drives the cross shaft 27 to rotate synchronously. While rotating, it will twist and tighten the torsion spring 26, which is convenient for subsequent reset. At the same time, the rotation of the first gear 25 will drive the rotating frame 8 and the rotating plate 9 to rotate together until the limit groove 801 on the outer wall of the rotating frame 8 gradually approaches and closes with the limit groove 801 on the outer wall of the first fixing frame 6, clamping the drainage catheter main body 5 between the two limit grooves 801. It should be noted that the initial states of the rotating frame 8 and the rotating plate 9 are in a rotating and open state due to the action of the torsion spring 26; At this time, continue to start the electric telescopic rod 10. When the first slider 23 continues to move and touches the outer wall of the second fixing frame 7, at this time, since the first slider 23 cannot move further, as the first fixing block 11 drives the first guide rod 21 to continue to move, the second spring 22 will be continuously compressed, and the first guide rod 21 will continuously slide along the inner wall of the first slider 23 towards the direction close to the second fixing frame 7; During the sliding process, the first contact block 30 at the end of the first guide rod 21 will contact the second contact block 35 on the outer wall of the second slider 34, the third slider 37 and the fourth slider 40 in sequence, causing the second inclined surface 32 of the outer wall of the first contact block 30 and the third inclined surface 36 on one side of the outer wall of the second contact block 35 to contact each other. The contact will cause the second contact block 35 to be forced to carry the corresponding second slider 34, the third slider 37 and the fourth slider 40 to slide along the inner wall of the support frame 51 in the direction close to the drainage catheter body 5, and the corresponding third spring 33 will be stretched during the sliding process to facilitate subsequent resetting, and the second slider 34, the third slider 37 and the fourth slider 40 will be forced to slide along the inner wall of the support frame 51 in the direction close to the drainage catheter body 5. The block 37 and the fourth slider 40 move synchronously with the end clamps 38 in turn, and cooperate with the clamps 38 at the ends of the third fixing block 42, the fourth fixing block 43 and the fifth fixing block 44, and clamp and press the drainage catheter body 5 between the clamps 38 on both sides in turn, and when the first abutting block 30 releases the abutment with the corresponding second abutting block 35, due to the reset effect of the third spring 33, the corresponding second slider 34, the third slider 37 and the fourth slider 40 will slide and reset, so as to press multiple positions of the drainage catheter body 5, take anti-blocking measures before intubation and during drainage, and ensure that the drainage catheter body 5 is unobstructed; And because the third slider 37 and the fourth slider 40 are connected by the first connecting plate 39, when the third slider 37 is moved by the resistance, the fourth slider 40 will move together, and when the fourth slider 40 is moved by the resistance, the third slider 37 will move together; And because the third fixing block 42 is shorter, that is, the splint 38 corresponding to the third fixing block 42 is further away from the drainage catheter body 5, so when the second slider 34 slides with the splint 38 to squeeze the outer wall of the drainage catheter body 5, the drainage catheter body 5 will be pressed and bent for a distance so that the outer wall of the drainage catheter body 5 can be abutted against the splint 38 corresponding to the third fixing block 42, thereby obtaining a supporting force, and at this time, the pressed end of the drainage catheter body 5 is bent in the direction close to the third fixing block 42, and the pressing during the bending process can make the inner cross-section of this section of the drainage catheter body 5 squeeze and deform to become narrower, and at this time, pressing the drainage catheter body 5 will cause the deformation to prompt the liquid in the drainage catheter body 5 to flow through the narrowed section of the drainage catheter body 5, so that the flow rate of this section of the drainage catheter body 5 becomes larger, and the blockage is better cleared, so that the thrombus or other coagulation in the drainage catheter is washed away by the greater pressure of the fluid, and the process of the drainage catheter body 5 being reset after being pressed and bent is also conducive to preventing blockage in the drainage catheter body 5; When the first abutting block 30 moves to a certain position, at this time, the second guide rod 28 on the outer wall of the first abutting block 30 will drive the second ball 29 to abut against the fourth inclined surface 50, causing the third abutting block 49 to be stressed and drive the second connecting plate 48 and the fifth slider 46 to move in the direction of stretching the fourth spring 45. At this time, the fifth slider 46 will drive the corresponding clamping plate 38 to press the drainage catheter body 5. Since the second fixing block 41 is short, the fifth slider 46 will drive the corresponding clamping plate 38 to first press and bend the drainage catheter body 5 before it can abut against the clamping plate 38 corresponding to the second fixing block 41 to clamp the drainage catheter body 5. And at this time, the bending direction of this section of the drainage catheter body 5 is opposite to the previous bending direction, which can better and more evenly prevent the drainage catheter body 5 from being blocked; By continuously starting the electric telescopic rod 10, through the telescopic and reset of the output end of the electric telescopic rod 10, the first guide rod 21 can be driven to move reciprocally, so as to realize the repeated bending and reciprocating pressing of different parts of the outer wall of the drainage catheter body 5; It should be noted that since the drainage catheter body 5 is pressed or bent, it may cause the accumulated fluid that has been discharged from the patient's body in the drainage catheter body 5 to flow back. Therefore, to avoid this situation, when the output end of the electric telescopic rod 10 extends and drives the first fixing block 11 to move, the movement of the first fixing block 11 will drive the support frame 12 to move synchronously. During the movement of the support frame 12, the first ball 13 on its outer wall will abut along the spiral groove 20. Since the support frame 12 cannot rotate, this abutment will cause the rotating ring 19 to drive the spiral groove 20 to rotate along the outer wall of the moving plate 15. The rotation of the rotating ring 19 will drive the two dial plates 17 at its end to rotate synchronously. The rotation of the two dial plates 17 will twist the drainage catheter body 5 between the two dial plates 17, so that this section of the drainage catheter body 5 is torsionally deformed and cannot continue to flow. When the first ball 13 moves to the end of the spiral groove 20, at this time, as the first fixing block 11 and the first guide rod 21 continue to move, the latter section of the drainage catheter body 5 will start to be bent and squeezed. And at this time, the moving plate 15 will be stressed to stretch the first spring 16 so that it slides along the outer wall of the first guide rod 14 to prevent jamming; And when the rotating ring 19 drives the two dial plates 17 to move along with the dial plates 17, at this time, due to the multiple rollers 18 rotatably arranged on the outer wall of the dial plate 17, the drainage catheter body 5 that is torsionally blocked at this time will relatively move along the multiple rollers 18 between the two dial plates 17 to prevent jamming; The entire device is adhered to the patient's waist and abdomen through the adhesive surface patch 101 to prevent the guide tube and the device from falling off. Moreover, the bolt 3 can be removed by rotation, and the adhesive surface patch 101 can be torn off and replaced with a new one for repeated use. After pasting the new adhesive surface patch 101 on the lower surface of the flexible fixing plate 1, it can be pressed through the conical head 4 against the opening of the threaded groove 103 to pierce the new adhesive surface patch 101. Subsequently, the bolt 3 is screwed into the threaded groove 103 through a threaded connection. The end of the bolt 3 can be received in the groove 102 to prevent protrusion from causing discomfort to the patient's skin.

[0024] Refer to Figure 10 and Figure 11 , Tighten the tightening wire 911, and the tightening wire 911 includes a part disposed inside the elastic abdominal belt main body 91 and a part exposed outside the elastic abdominal belt main body 91; Both ends of the tightening wire 911 located inside the elastic abdominal belt main body 91 are fixedly connected to both ends of the elastic abdominal belt main body 91 respectively; the part between the two ends of the tightening wire 911 and located inside the elastic abdominal belt main body 91 can slide relatively inside the elastic abdominal belt main body 91; It further includes a tightening structure for tightening the tightening wire 911. The tightening structure includes a fixing piece 915 and a winding column 914 mounted on the fixing piece 915. A space for accommodating the tightening wire 911 is formed between the two winding columns 914; The tightening structure further includes a first abdominal belt fastener 912 and a second abdominal belt fastener 913 mounted on the fixing piece 915; When using the tightening structure to tighten the abdominal belt, first place the tightening wire 911 between the two winding columns 914, in the specific state as Figure 1 shown. After that, rotate the tightening structure so that the tightening wire 911 is wound around the two winding columns 914. Here, the number of rotation turns can be adjusted according to the required tightening degree.
