Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a device for regulating the flow of blood from one's own blood vessels. Background Technology

[0002] Acute lower limb ischemia is a significant problem in vascular surgery. If not treated promptly and effectively, it can cause irreversible limb damage, leading to serious consequences such as amputation. The immediate priority after lower limb ischemia is to restore adequate blood flow to the patient. However, the process of restoring blood supply can cause further damage, including varying degrees of injury to surrounding muscle tissue and distal organs.

[0003] Similarly, after carotid endarterectomy and acute lower limb ischemia reversal, the corresponding target organs (brain and lower limbs) are prone to hyperperfusion symptoms.

[0004] Therefore, it is necessary to develop a blood flow control device suitable for use after peripheral vascular recanalization surgery. This device would be implanted outside the patient's own blood vessel post-surgery, with a release lead and drainage tube led out to the body surface and secured. The blood flow control device would be released in stages at predetermined post-operative time points to achieve orderly blood flow release. Summary of the Invention

[0005] The purpose of this invention is to provide a device for regulating autologous blood flow, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for regulating autologous blood flow includes: a soft cannula and an adjusting seat.

An adjusting knob is fixedly connected to one end of one shaft and is located outside the adjusting cavity. A take-up roller is fixedly connected to the outer wall of one shaft. A through-hole is opened on one side of the outer wall of the adjusting seat and communicates with the adjusting cavity. An adjusting pointer is slidably connected to the inner wall of the through-hole. A connecting wire is fixedly connected to one side of the outer wall of the adjusting pointer, and one end of the connecting wire is fixedly connected to the outer wall of the take-up roller. A return spring is fixedly connected to one side of the inner wall of the adjusting cavity, and one end of the return spring is fixedly connected to one side of the outer wall of the adjusting pointer.

[0007] The device for regulating autologous blood flow as described above: a mounting rod is fixedly connected inside the regulating cavity, and a limiting member is rotatably connected to the outer wall of the mounting rod, with the outer wall of the limiting member in contact with the outer wall of the drive gear.

[0008] The device for regulating autologous blood flow as described above: an arc-shaped opening is provided on one side of the outer wall of the adjustment seat, the arc-shaped opening is connected to the adjustment cavity, and a movable rod is fixedly connected to one side of the outer wall of the limiting member.

[0009] As described above, the device for regulating autologous blood flow has the following characteristics: the outer wall of the movable rod is in contact with the inner wall of the arc-shaped opening, and a pressure spring is fixedly connected to one side of the inner wall of the adjustment cavity, with one end of the pressure spring fixedly connected to one side of the outer wall of the limiting member.

[0010] The device for regulating autologous blood flow as described above: a fixed sleeve is fixedly connected to the outer wall of the soft sleeve, the same fixed rod is fixedly connected to the inner walls of both sides of the fixed sleeve, and a fixing member is rotatably connected to the outer wall of the fixing rod, and a fixing hole is opened on one side of the outer wall of the fixing member.

[0011] As described above, the device for regulating autologous blood flow has the following features: multiple supporting spring rods are fixedly connected at equal intervals to one side of the inner wall of the fixed sleeve; one end of each of the multiple supporting spring rods is fixedly connected to two protective pads to one side of the inner wall of the fixed component; and one side of the outer wall of each of the two protective pads is in contact with the outer wall of the second adjusting belt; and one end of the second adjusting belt is provided with a connector.

[0012] As described above, the device for regulating autologous blood flow has a fixing opening on one side of the outer wall of the fixing sleeve, a fixing spring is fixedly connected to the inner wall of one side of the fixing opening, and a snap-fit ​​is fixedly connected to one end of the fixing spring, and the snap-fit ​​engages with the fixing hole.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

During operation, internal blood vessels can be adjusted externally to improve the convenience of the device. Furthermore, during adjustment, the take-up roller, connecting line, adjustment pointer, and return spring allow for precise observation of the adjustment degree, thereby improving the accuracy of the device's adjustment and adapting to different grafting sites and varying physical conditions. After adjustment and fixation, the return spring can reset the adjustment pointer for subsequent use; 2. By providing a limiting component, mounting rod, movable rod, and arc-shaped opening... With the pressure spring, after adjustment, the drive gear can be fixed by the limiting component, movable rod, and arc-shaped opening. This prevents the adjusting roller from loosening when fixing adjusting belt one and adjusting belt two, thus preventing adjusting belt one from being loose and affecting the adjustment effect. This ensures the stability of the device during use and further improves the device's performance and accuracy. 3. By setting a fixed sleeve, fixed rod, fixed component, protective pad, support spring rod, snap-fit ​​component, and fixed spring, adjusting belt two can be fixed before adjustment, making it convenient for medical personnel to adjust blood flow. Disassembly is also convenient. At the same time, when fixing, the support spring rod and protective pad increase the friction between the protective pad and adjusting belt two, thereby increasing the device's fixing effect. The protective pad also prevents wear on the surface of adjusting belt two during fixing. Attached Figure Description

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0022] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] Please see Figure 1-5 In this embodiment of the invention, a device for regulating autologous blood flow includes: a soft sleeve 1 and an adjusting seat 4. The adjusting seat 4 has an adjusting cavity inside, and two shafts 10 are rotatably connected inside the adjusting cavity. Adjusting rollers 11 are fixedly connected to the outer walls of both shafts 10. The soft sleeve has an adjusting belt 3 and an adjusting belt 5 inside, and the outer walls of both adjusting rollers 11 are in contact with the outer walls of the adjusting belt 3. Driven gears 12 and driving gears 13 are fixedly connected to the outer walls of the two shafts 10, and the driven gears 12 and driving gears 13 mesh. One of the driven gears... One end of the shaft 10 is fixedly connected to an adjustment knob 6, which is located outside the adjustment cavity. A take-up roller 20 is fixedly connected to the outer wall of one of the shafts 10. An opening 8 is provided on one side of the outer wall of the adjustment seat 4, which is connected to the adjustment cavity. An adjustment pointer 7 is slidably connected to the inner wall of the opening 8. A connecting wire 19 is fixedly connected to one side of the outer wall of the adjustment pointer 7, and one end of the connecting wire 19 is fixedly connected to the outer wall of the take-up roller 20. A return spring 18 is fixedly connected to one side of the inner wall of the adjustment cavity, and one end of the return spring 18 is fixedly connected to one side of the outer wall of the adjustment pointer 7.

[0024] It should be noted that during adjustment, medical staff rotate the adjustment knob 6, which drives the shaft 10 and the adjustment roller 11 to rotate. Simultaneously, since the drive gear 13 meshes with the driven gear 12, it drives the two adjustment rollers 11 to rotate, causing the adjustment rollers 11 to move the adjustment belt 3, thereby tightening the adjustment belt 3 and the adjustment belt 5. During adjustment, the shaft 10 can drive the take-up roller 20 to rotate, thereby winding the connecting line 19, which in turn causes the connecting line 19 to move the adjustment pointer 7, allowing medical staff to observe the adjustment degree in real time. After the adjustment is completed, the excess adjustment belt 3 and the adjustment belt 5 are cut off. At this time, the return spring 18 can drive the adjustment pointer 7 to reset.

[0025] In this invention, an installation rod 17 is fixedly connected inside the adjustment cavity, and a limiting member 14 is rotatably connected to the outer wall of the installation rod 17, and the outer wall of the limiting member 14 is in contact with the outer wall of the drive gear 13.

[0026] In this invention, an arc-shaped opening 9 is provided on one side of the outer wall of the adjusting seat 4, and the arc-shaped opening 9 is connected to the adjusting cavity. A movable rod 15 is fixedly connected to one side of the outer wall of the limiting member 14.

[0027] In this invention, the outer wall of the movable rod 15 is in contact with the inner wall of the arc-shaped opening 9, and a pressure spring 16 is fixedly connected to one side of the inner wall of the adjustment cavity. One end of the pressure spring 16 is fixedly connected to one side of the outer wall of the limiting member 14.

[0028] Specifically, after adjustment, the drive gear 13 will contact the outer wall of the limiting member 14. At this time, the limiting member 14 can fix the drive gear 13. When the drive gear 13 becomes loose, it will reverse. At this time, the limiting member 14 will drive the movable rod 15 to move. During the movement, the arc-shaped opening 9 can limit the movable rod 15, so that the limiting member 14 and the drive gear 13 cannot move, thus ensuring the stability of the device. After use, by moving the movable rod 15 inside the arc-shaped opening 9, the drive gear 13 can be separated from the limiting member 14, which facilitates the reset operation of the device.

[0029] In this invention, a fixing sleeve 2 is fixedly connected to the outer wall of the soft sleeve 1, and the same fixing rod 25 is fixedly connected to the inner walls of both sides of the fixing sleeve 2. A fixing member 22 is rotatably connected to the outer wall of the fixing rod 25, and a fixing hole 23 is opened on one side of the outer wall of the fixing member 22.

[0030] In this invention, a plurality of supporting spring rods 24 are fixedly connected at equal intervals on one side inner wall of the fixed sleeve 2. One end of the plurality of supporting spring rods 24 is fixedly connected to two protective pads 21 on one side inner wall of the fixing member 22, and the outer wall of one side of the two protective pads 21 is in contact with the outer wall of the adjusting belt 2 5. One end of the adjusting belt 2 5 is provided with a connector 28.

[0031] In this invention, a fixing opening is provided on one side of the outer wall of the fixing sleeve 2, and a fixing spring 26 is fixedly connected to the inner wall of one side of the fixing opening. A snap-fit ​​member 27 is fixedly connected to one end of the fixing spring 26, and the snap-fit ​​member 27 is snapped into the fixing hole 23.

[0032] In a specific application scenario, during use, the first adjustment belt 3 and the second adjustment belt 5 are connected by the connector 28, and the adjustment knob 6 is used to prevent the connector 28 from contacting the blood vessel. After moving to a certain position, the fixing member 22 is fixed by the snap-fit ​​member 27 and the fixing spring 26, thereby fixing the second adjustment belt 5. At this time, the support spring rod 24 deforms and provides a thrust towards the fixing member 22, so that the two protective pads 21 clamp the second adjustment belt 5, preventing loosening during adjustment, ensuring adjustment accuracy, and the protective pads 21 can prevent the second adjustment belt 5 from wearing.

[0033] Working principle: During use, the adjusting belt 3 and adjusting belt 5 are connected via connector 28. The adjusting knob 6 prevents the connector 28 from contacting the blood vessel. After moving to a certain position, the fixing piece 22 is secured by the snap-fit ​​piece 27 and the fixing spring 26, thus securing adjusting belt 5. During adjustment, medical personnel rotate the adjusting knob 6, which drives the shaft 10 and adjusting roller 11 to rotate. Simultaneously, the drive gear 13 meshes with the driven gear 12, causing the two adjusting rollers 11 to rotate, thus moving adjusting belt 3 and tightening adjusting belt 3 and adjusting belt 5. During adjustment, the shaft 10 drives the take-up roller 20 to rotate, thereby tightening the connecting wire 19. The winding causes the connecting wire 19 to move the adjusting pointer 7. After adjustment, the drive gear 13 will contact the outer wall of the limiting member 14. At this time, the limiting member 14 can fix the drive gear 13. When the drive gear 13 becomes loose, it will reverse. At this time, the limiting member 14 will drive the movable rod 15 to move. During the movement, the arc-shaped opening 9 can limit the movable rod 15, so that the limiting member 14 and the drive gear 13 cannot move. After use, by moving the movable rod 15 inside the arc-shaped opening 9, the drive gear 13 can be separated from the limiting member 14. After adjustment, the excess adjusting belt 1 3 and adjusting belt 2 5 are cut off. At this time, the adjusting pointer 7 can be reset by the return spring 18.
