Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a special flushing device for IABP with a timing reminder function. Background Art

[0002] Intra-aortic balloon pump (IABP) is mainly used for circulatory support of patients with cardiogenic shock, hemodynamic instability during the perioperative period of the heart, or heart failure. With the continuous development of IABP technology, it has been widely used in the treatment of critically ill patients. According to literature reports, the most common complication of applying IABP is lower limb ischemia, which occurs in 5% - 10% of patients. The main reasons include thrombus detachment, thrombus formation around the balloon catheter, etc. If lower limb ischemia occurs on the implanted side, the IABP catheter will be removed as soon as possible clinically to avoid continuous lower limb ischemia, necrosis, and even systemic sepsis, which may seriously lead to the death of the patient. Regular flushing of the IABP pipeline can prevent thrombus formation. During the use of IABP, anticoagulants need to be used to flush the IABP catheter regularly and quantitatively to prevent thrombus formation. Generally, nurses need to manually flush the heparin saline under pressure once an hour, and each time it should not exceed 15 seconds.

[0003] During the period when the IABP catheter is indwelling in the patient's body, the components in the blood may adhere to the inner wall of the catheter. Over time, it is easy to form thrombus and block the pipeline. The flushing device can flush the IABP pipeline with flushing solutions such as heparin saline regularly to remove these attached substances in time, keep the pipeline unobstructed, ensure that the IABP device can work normally, and continuously provide effective cardiac assist support for the patient.

[0004] When the existing equipment is in use, since heparin saline is prepared from two liquids, heparin solution and normal saline, it needs to be fully mixed before flushing the pipeline. However, most of the existing equipment is not convenient for slight shaking treatment, which may lead to phenomena such as stratification or uneven solution concentration in the heparin saline, reducing the flushing quality. Therefore, we propose a special flushing device for IABP with a timing reminder function.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to provide a special flushing device for IABP with a timing reminder function. Through a shaking mechanism, a positioning mechanism, and a stabilizing mechanism, it solves the problem that when the existing equipment is in use, since heparin saline is prepared from two liquids, heparin solution and normal saline, it needs to be fully mixed before flushing the pipeline.

[0019] The present invention has the following beneficial effects:

[0020] 1. By setting the L-shaped rotating rod on the rotating shaft, when the device needs to be used, the rotation of the motor can drive the rotation of the rotating shaft, and the rotation of the L-shaped rotating rod can drive the spherical limit block to rotate in the spherical limit hole. Since the geometric center of the spherical limit block is not at the same height as the geometric center of the rotating shaft, when the rotating shaft rotates, it will drive the spherical limit block to perform eccentric motion around the rotating shaft seat, thereby making the connecting column move, achieving the effect of making heparin dissolve more fully in physiological saline, ensuring that the solution concentration is uniform, making the anticoagulant effect of the flushing solution relatively stable for each use, avoiding the influence of uneven local concentration on the flushing effect and anticoagulant effect, preventing precipitation or stratification in the heparin saline, increasing the contact area between heparin and physiological saline, accelerating the dissolution speed, and enabling the heparin saline to reach a suitable state for use as soon as possible.

[0021] 2. By setting the second limit shaft on the sliding rod, when the device is in use, the end of the flexible infusion pipeline close to the infusion bag is placed between the clamping plates. Then, the threaded rod sleeve is rotated. The rotation of the threaded rod sleeve can drive the threaded rod to move away from the second connecting frame, and the movement of the threaded rod can drive the third fixed block away from the second connecting frame, thereby making the fourth limit shaft away from the second connecting frame. When the fourth limit shaft moves away from the second connecting frame, it can simultaneously pull multiple connecting rods away from the connecting rod, achieving the effect of fixing the position of the infusion bag when shaking the infusion bag, ensuring that it stably receives shaking under the action of the device, and fully mixing the heparin saline in the bag.

[0022] 3. In the present invention, by providing a worm gear on the second threaded rod, when the device is in use, first inject heparin solution and normal saline into the infusion bag, and adsorb the second connecting frame on the skin periphery at the balloon pipeline insertion point on the patient. Subsequently, rotate the worm. Since the worm and the worm gear mesh with each other, the rotation of the worm can drive the rotation of the worm gear, causing the second threaded rod to rotate. Since multiple racks all mesh with the gear, the rotation of the second threaded rod can drive the movement of the upper rack, achieving the effect of fixing the balloon pipeline at the insertion point with the patient's body, which can prevent the pipeline from shaking during flushing of the balloon pipeline, causing pain to the patient. At the same time, it can prevent the pipeline from shifting or even completely slipping out of the body due to the patient's daily activities, turning over, limb movement, etc. Moreover, when the balloon pipeline is fixed properly, it can ensure the smooth flow of heparinized saline liquid during the flushing process, preventing thrombus formation and blockage.

[0023] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the new type of the present invention, rather than all the embodiments. Based on the embodiments of the new type of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the new type of the present invention.

[0038] Please refer to Figure 1-10As shown in the figure, the novel invention of the present invention is a special flushing device for IABP with a timing reminder function, including a timing controller 1. A plurality of wires 101 are fixedly connected to the bottom output end of the timing controller 1. A booster pump 102 is fixedly connected to the outer wall of the wire 101 on the left side. By setting the booster pump 102, when the booster pump 102 is started, the heparinized saline in the infusion bag 105 can be pumped out and transported into the balloon pipeline 107 for flushing operation. The bottom output end of the booster pump 102 is plugged with a flexible infusion pipeline 104. The outer wall of the flexible infusion pipeline 104 is plugged with an infusion bag 105. A shaking mechanism 2 is arranged on the outer wall of the infusion bag 105. By setting the infusion bag 105, the heparinized saline required for flushing can be centrally placed, which is convenient for medical staff to configure it. At the same time, the infusion bag 105 can prevent the heparinized saline from being contaminated during flushing;

[0039] The shaking mechanism 2 includes a placement plate 201, the outer wall of the placement plate 201 is slidably connected to the outer wall of the infusion bag 105, a hook 202 is fixedly connected to the outer wall of the placement plate 201, and a connecting column 203 is fixedly connected to the outer wall of the end of the placement plate 201 away from the infusion bag 105. By providing the hook 202, it is convenient for the user to hang on the placement plate 201, facilitating the subsequent fixation of the infusion bag 105. At the central axis of the inner wall of the end of the connecting column 203 away from the placement plate 201, a spherical limiting hole 204 is provided. A spherical limiting block 205 is slidably connected to the inner wall of the spherical limiting hole 204. An L-shaped rotating rod 206 is fixedly connected to the outer wall of the end of the spherical limiting block 205 away from the placement plate 201. Since the inner wall of the spherical limiting hole 204 is wider inside and narrower outside, it can prevent the spherical limiting block 205 from falling off when rotating in the spherical limiting hole 204. A rotating shaft 207 is fixedly connected to the inner wall of the L-shaped rotating rod 206. A negative pressure pump 103 is fixedly connected to the outer wall of the right-side wire 101. The outer wall of the flexible infusion pipeline 104 is inserted into the bottom output end of the negative pressure pump 103. A four-way valve 106 is inserted into the outer wall of the flexible infusion pipeline 104. By providing the four-way valve 106, the connection state between the flexible infusion pipeline 104 and the balloon pipeline 107 can be freely controlled, facilitating the flow of heparinized saline. The end of the four-way valve 106 away from the flexible infusion pipeline 104 has a balloon pipeline 107 inserted into its inner wall. A limiting rod 208 is rotatably connected to the inner wall of the connecting column 203. An annular limiting block 209 is rotatably connected to the outer wall of the limiting rod 208. A number of limiting shafts 210 are rotatably connected to the inner wall of the annular limiting block 209. The limiting shafts 210 can limit the position of the annular limiting block 209, enabling the annular limiting block 209 to only perform circular motion around the limiting shafts 210 and preventing the annular limiting block 209 from falling off. A connecting frame 211 is fixedly connected to the outer wall of the limiting shaft 210. A support column 212 is fixedly connected to the outer wall of the end of the connecting frame 211 away from the placement plate 201. A number of positioning bolts 213 are threadedly connected to the inner wall of the support column 212. A motor frame 214 is fixedly connected to the outer wall of the end of the connecting frame 211 close to the rotating shaft 207. By providing the motor frame 214, the position of the motor 215 can be fixed, preventing the motor 215 from affecting the subsequent normal transmission due to excessive self-shaking amplitude during operation.

[0040] The inner wall of the motor mount 214 is fixedly connected to a motor 215. The bottom output end of the motor 215 is fixedly connected to the outer wall of the rotating shaft 207. The inner wall of one end of the flexible infusion pipeline 104 close to the infusion bag 105 is fixedly connected to a stop valve 216. A positioning mechanism 3 is arranged on the outer wall of the placement plate 201. By providing the stop valve 216, it can prevent the heparin saline in the flexible infusion pipeline 104 from flowing back into the infusion bag 105, resulting in contamination of the unused heparin saline in the infusion bag 105. The positioning mechanism 3 includes a second connecting frame 301. The outer wall of the second connecting frame 301 is fixedly connected to the outer wall of the placement plate 201. A plurality of sliding rods 302 are slidably connected to the inner wall of the second connecting frame 301. A plurality of second limiting shafts 303 are rotatably connected to the inner walls of the plurality of sliding rods 302. By providing the second limiting shafts 303, the positions of the clamping plate 304, the fixing block 306 and the connecting rod 310 can be limited, so that they can only perform circular motion around the second limiting shafts 303. A clamping plate 304 is rotatably connected to the outer wall of the middle second limiting shaft 303. A third limiting shaft 305 is rotatably connected to the inner wall of the clamping plate 304. The outer walls of the second limiting shafts 303 on the left side and the outer wall of the third limiting shaft 305 are both rotatably connected to fixing blocks 306. A telescopic rod 307 is fixedly connected to the outer wall of the fixing block 306. By providing the telescopic rod 307, the position movement trajectory of the spring 308 can be limited, preventing the telescopic rod 307 from breaking during the telescopic process. A spring 308 is fixedly connected to the outer wall of the fixing block 306 close to the telescopic rod 307. A third limiting rod 309 is fixedly connected to the inner wall of one end of the plurality of sliding rods 302 close to the fixing block 306. A connecting rod 310 is slidably connected to the outer walls of the plurality of sliding rods 302. By providing the connecting rod 310, when the connecting rod 310 moves, it can drive the second limiting shaft 303 on the right side to move, thereby causing the entire sliding rod 302 to displace. The outer wall of the second limiting shaft 303 on the right side is rotatably connected to the inner wall of the second connecting frame 301. A fourth limiting shaft 311 is rotatably connected to the inner wall of the end of the connecting rod 310 away from the second limiting shaft 303. A third fixing block 312 is rotatably connected to the outer wall of the fourth limiting shaft 311. A threaded rod 313 is fixedly connected to the outer wall of the third fixing block 312 close to the second connecting frame 301. By providing the fourth limiting shaft 311, the positions of the connecting rod 310 and the third fixing block 312 can be limited, so that the connecting rod 310 and the third fixing block 312 can only perform circular motion around the fourth limiting shaft 311, and at the same time, the threaded rod 313 can be prevented from falling off. A threaded rod sleeve 314 is threadedly connected to the outer wall of the threaded rod 313. The outer wall of the threaded rod sleeve 314 is rotatably connected to the inner wall of the second connecting frame 301. A stabilizing mechanism 4 is arranged on the outer wall of the balloon pipeline 107. By providing the threaded rod sleeve 314, when the threaded rod sleeve 314 is rotated, it can drive the threaded rod 313, causing the threaded rod 313 to move in a direction away from or close to the second connecting frame 301.

[0041] The stabilizing mechanism 4 includes a suction cup 401, the outer wall of which is fixedly connected to the outer wall of the balloon pipeline 107, the outer wall of the suction cup 401 is fixedly connected to a fixing plate 402, the inner wall of the fixing plate 402 is fixedly connected to a plurality of fixing blocks 403, by setting the fixing blocks 403, the positions of the threaded rod 405 and the sliding rod 410 can be limited so that they can only rotate within the fixing blocks 403 and can be prevented from falling off, the inner wall of one end of the fixing plate 402 close to the fixing block 403 is rotatably connected to a worm 404, the inner wall of the fixing block 403 at the upper end is rotatably connected to a threaded rod 405, the outer wall of one end of the threaded rod 405 close to the worm 404 is fixedly connected to a worm wheel 406, the outer wall of the worm wheel 406 The outer wall of the worm 404 is meshed with the worm gear 406. Therefore, when the worm 404 is rotated, the worm gear 406 can be driven to rotate, thereby rotating the threaded rod 405. The inner wall of the suction cup 401 is fixedly connected with an annular limit block 407. The outer wall of the annular limit block 407 is slidably connected with a gear 408. The inner wall of one end of the fixed plate 402 close to the fixed block 403 is slidably connected with a plurality of racks 409. The inner wall of the upper end rack 409 is threadedly connected with the outer wall of the threaded rod 405. The annular limit block 407 can limit the position of the gear 408 so that the gear 408 can only rotate on the annular limit block 407. At the same time, it can prevent the gear 408 from falling off. The inner wall of the end fixing block 403 is fixedly connected with a slide bar 410, and the inner wall of the rack 409 at the lower end is slidably connected with the outer wall of the slide bar 410, and the outer walls of the ends of the several racks 409 away from the suction cup 401 are fixedly connected with a toothed slider 411. Since the toothed slider 411 and the toothed slider 412 are meshed with each other, the toothed slider 411 can be driven to move when the rack 409 moves, so that the toothed slider 412 can move closer to or away from the direction of the balloon pipeline 107 in the fixed plate 402. The inner wall of the end of the fixed plate 402 close to the toothed slider 411 is slidably connected with several toothed sliders 412, and the outer wall of the toothed slider 412 is slidably connected to the outer wall of the toothed slider 411. 412 slides in the fixed plate 402, so the toothed slider 412 can only slide along the direction of the limiting slide groove of the fixed plate 402, and the fixed plate 402 can prevent the toothed slider 412 from falling off. The outer walls of one end of several toothed sliders 412 close to the balloon pipeline 107 are fixedly connected with telescopic rods 413, and the outer walls of one end of several telescopic rods 413 close to the balloon pipeline 107 are fixedly connected with anti-skid splints 415. Since the inner wall of the anti-skid splints 415 has anti-skid grooves, the friction between the anti-skid splints 415 and the balloon pipeline 107 can be increased to prevent sliding and improve the positioning effect of the anti-skid splints 415. The outer wall of the anti-skid splints 415 is slidably connected to the outer wall of the balloon pipeline 107.The outer wall of the anti-skid splint 415 near the end of the telescopic rod 413 is fixedly connected with the spring 414, and the outer wall of the spring 414 is fixedly connected with the outer wall of the toothed slider 412. The spring 414 will always support the anti-skid splint 415 due to its own elastic force to make it close to the outer wall of the balloon pipeline 107, so as to position the balloon pipeline 107.

[0042] A specific application of this embodiment is:

[0043] When the staff needs to use the device, before use, the heparin solution and saline solution are first injected into the infusion bag 105, and the connecting frame 2 301 is adsorbed on the patient's skin outside the balloon tube 107, and then the worm 404 is rotated. Since the worm 404 and the worm wheel 406 are meshed with each other, the rotation of the worm 404 can drive the worm wheel 406 to rotate and rotate the threaded rod 2 405. Since multiple racks 409 are meshed with the gear 408, the rotation of the threaded rod 2 405 can drive the upper rack 409 to move, and then rotate on the annular limit block 2 407, and then the lower rack 409 will be on the slide bar 2 410 and in the opposite direction of the movement of the upper rack 409. The movement of the rack 409 can drive the toothed slider 411 movement, since the fixed plate 402 limits the movement trajectory of the toothed slider 412, and the toothed slider 412 and the toothed slider 411 are meshed with each other, the movement of the toothed slider 411 can drive the toothed slider 412 to gather toward the middle direction, thereby driving the multiple telescopic rods 413 and the spring 414 to move toward the middle at the same time, so that the anti-skid splint 415 is tightly attached to the outer wall of the balloon pipeline 107, and the pressure is continuously applied to fix the balloon pipeline 107 at the anti-skid splint 415, and place one end of the flexible infusion pipeline 104 close to the infusion bag 105 between the splints 304, and then rotate the threaded rod sleeve 314, the rotation of the threaded rod sleeve 314 can drive the threaded rod 313 to move in the direction away from the connecting frame 301, and the threaded rod The movement of 313 can drive the fixed block three 312 away from the connecting frame two 301 and thus make the limiting shaft four 311 away from the connecting frame two 301. When the limiting shaft four 311 moves away from the connecting frame two 301, multiple connecting rods 310 can be pulled away from the connecting rod 310 at the same time. The movement of the connecting rod 310 can pull the limiting shaft two 303 on the right side to move and thus make the sliding rod 302 slide in the connecting frame two 301 in the direction away from the connecting frame two 301. When multiple sliding rods 302 slide at the same time, the distance between the sliding rods 302 will gradually shorten. At this time, the movement of the sliding rod 302 can drive the limiting shaft two 303 in the middle to move so that the splint 304 gradually moves closer and clamps the interface between the bottom of the infusion bag 105 and the flexible infusion pipeline 104 to prevent the infusion bag 105 from sliding slightly in the subsequent During the movement, displacement or even falling occurs. When fixing infusion bags 105 of different thicknesses, when the splint 304 clamps the interface of the infusion bag 105, the splint 304 can rotate around the middle splint 304 to the periphery, thereby pulling the fixing block 306 on the limit axis three 305 to move, and stretching the spring 308 and the telescopic rod 307. At this time, the spring 308 will drive the fixing block 306 to reset due to its own elastic force, thereby resetting the splint 304, so that the splints 304 are in an elastic clamping state. The connecting frame 211 is installed around the patient's bed through the support column 212 and the positioning bolt 213. When in use, the flushing time is controlled by the knob on the timing controller 1, and the timing controller 1 is started to control the four-way valve 106.The left side of the flexible infusion line 104, the right side of the four-way valve 106 and the balloon line 107, and the infusion bag 105 are interconnected, so that the balloon line 107 cannot be further filled with gas. When the timing controller 1 is started, the booster pump 102 can be driven to operate through the left wire 101, and then the heparin solution in the infusion bag 105 is transported from the infusion bag 105 to the right side of the balloon line 107, and the balloon is flushed and cleaned, and then the booster pump 102 is turned off and adjusted. Adjust the four-way valve 106 to make the right side of the flexible infusion line 104 and the right side of the four-way valve 106 and the balloon line 107 interoperable, and start the negative pressure pump 103. At this time, the heparin solution used for flushing the balloon line 107 can be discharged from the outlet on the right side of the flexible infusion line 104, completing the cleaning of the inside of the balloon line 107. The heparin solution flows in and out of the balloon line 107 to simulate the normal operation of the IABP device. When the motor 215 is started, the motor The rotation of the L-shaped rotating rod 206 can drive the rotating shaft 207 to rotate, and the rotation of the L-shaped rotating rod 206 can drive the spherical stopper 205 to rotate in the spherical stopper hole 204. Since the geometric center of the spherical stopper 205 is not at the same height as the geometric center of the rotating shaft 207, the rotation of the rotating shaft 207 will drive the spherical stopper 205 to make an eccentric circle motion around the rotating shaft 207, thereby causing the connecting column 203 to move. The connecting column 203 moves on the stopper rod 208. During upward movement, since the position of the annular stopper 209 is limited by the limit shaft 210, the connecting column 203 moves or slightly shakes up and down, left and right, thereby driving the infusion bag 105 to slightly shake, so that the heparin saline in the infusion bag 105 is fully shaken. After the countdown ends, the flushing is completed. At this time, the timing controller 1 will automatically stop the operation between the booster pump 102 and the negative pressure pump 103, and give a voice reminder to the user through the speaker of the timing controller 1.
