Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a blood coagulation filtering device for hemodialysis. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of tens of thousands of hollow fibers. The blood and an electrolyte solution containing electrolytes at concentrations similar to those in the body exchange substances inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The entire process is called hemodialysis.

[0003] In the prior art, during the blood filtering process, impurities in the blood are generally cleaned by setting up a filter net. When the dialysis time is too long, the impurities in the blood may be clogged in the filter holes in the filter net, thereby affecting the blood circulation effect and being detrimental to the dialysis work for the patient.

[0012] Furthermore, sliders are fixedly connected to both sides of the bottom of the cross sleeve block, and a circular groove is opened at the center of the top of the filter plate. The outer wall of the slider is slidably connected to the inner wall of the circular groove.

[0013] Furthermore, a cleaning assembly is provided on the top of the cross sleeve block, and the cleaning assembly includes four bent rods fixedly connected around the top of the cross sleeve block, one end of the bent rod away from the cross sleeve block is fixedly connected to a heating shell, the bottom end of the inner wall of the heating shell is slidably connected to a piston plate, and return springs are respectively fixedly connected on both sides of the top of the piston plate.

[0014] Furthermore, the top of the return spring is fixedly connected to the top of the inner wall of the heating shell, and the bottom of the piston plate is fixedly connected to a plurality of conical rods. The outer wall of one end of the conical rod passes through the heating shell and extends to the outside of the heating shell, and the outer wall of the bottom end of the conical rod contacts the filter hole of the filter plate.

[0015] Furthermore, a heating component is provided on the inner wall of the heating shell, and the heating component includes a heater fixedly connected to the top of the inner wall of the heating shell. The two sides of the heating shell are respectively connected with bent pipes, and the end of the bent pipe away from the heating shell is connected with an exhaust hopper, and the bottom contact of the exhaust hopper is arranged on the top of the filter plate.

[0016] The present invention has the following beneficial effects:

[0017] (1) In the present invention, when a patient is undergoing hemodialysis, the inlet pump and the outlet pump are started simultaneously, and the inlet pump injects the patient's blood into the interior of the working cylinder. Then, the inlet pump generates suction to input the blood in the working cylinder into the patient's body. In this process, the two filter plates are arranged so that the blood can be filtered multiple times, thereby improving the dialysis effect of the patient. When the blood enters the interior of the working cylinder, the sliding plate slides inside the working cylinder, thereby blocking the blood and preventing the blood from circulating too quickly. The process of blood circulating inside the working cylinder enables the sliding plate to slide down inside the working cylinder. When the sliding plate moves to an area with a large radius inside the working cylinder, the blood can circulate, thereby performing dialysis on the patient. When the sliding plate slides down, the sliding plate drives the cross rod in the circulation component and the rotating component to descend. The cross rod is limited by the cross rod, and the cross rod slides up and down along the inner wall of the rotating ring, thereby limiting the lifting and lowering of the sliding plate, thereby preventing the position of the sliding plate from shifting during the lifting and lowering process, thereby improving the stability of the sliding plate operation.

[0018] (2) According to the present invention, when the sliding plate gradually moves away from the filter plate, the rotating rod will rotate slightly around the fixed ring at the filter plate, and limited by the limit groove, the rotating rod drives the limit rod to slide along the inner wall of the limit groove. Due to the setting of the arc-shaped hole at the top of the rotating plate, the limit rod causes the rotating plate to rotate along the top center of the sliding plate during the movement of the limit rod. The rotating plate drives the arc-shaped hole to rotate, the arc-shaped hole drives the cross sleeve block to rotate, the cross sleeve block drives the bent rod to rotate, the bent rod drives the heating shell to rotate, the heating shell drives the piston plate to rotate, the piston plate drives the conical rod to rotate, and due to the setting of the reset spring, when the conical rod When the bottom end docks with the filter holes of the filter plate, the tapered rod will slide along the inner wall of the filter holes of the filter plate to prevent impurities in the blood from getting stuck in the filter holes of the filter plate, thereby improving the blood circulation effect and the dialysis effect of the patient. When the cross rod rotates, the setting of the rotating ring can prevent the cross rod from contacting the filter plate during rotation, thereby improving the stability of the cross rod rotation. Because the cross rod drives the cross sleeve block to rotate, the cross sleeve block drives the slider to rotate, and the slider rotates inside the circular groove, thereby preventing the cross sleeve block from moving up and down on the outer wall of the cross rod, thereby improving the stability of the cross sleeve block operation.

[0019] (3) In the present invention, when the cross sleeve drives the bent rod to continue to rotate, the bottom end of the conical rod no longer docks with the filter hole of the filter plate. The conical rod is subjected to the reaction force of the filter plate, so that the piston plate is driven to slide upward inside the heating shell. The heater is set to heat the air flow inside the heating shell. When the piston plate moves up, the hot air flow inside the heating shell enters the inside of the bent pipe, and the hot air flow enters the inside of the exhaust hopper through the bent pipe. The hot air flow is sprayed toward the top of the filter plate through the exhaust hopper to heat the blood and prevent the blood from condensing after flowing into the working cylinder, thereby improving the blood circulation effect and further improving the dialysis effect of the patient.

[0020] (4) In the present invention, when the sliding plate moves to an area where the radius inside the working cylinder is too large, it is elastically stretched by the spring, and the spring drives the sliding plate to move upward, and the sliding plate drives the impact rod to move upward. During the upward movement, the impact rod collides with the bottom of the filter plate, causing the filter plate to vibrate slightly, thereby preventing impurities from remaining inside the filter holes of the filter plate when the conical rod slides inside the filter holes of the filter plate, thereby further improving the blood circulation effect. After the sliding plate moves upward, it is caused by the setting of the liquid inlet pump and the liquid outlet pump, causing the sliding plate to slide down again, thereby causing the device to reciprocate, thereby improving the dialysis effect of the device on blood.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The blood coagulation filtering mechanism 4 includes a filter plate 41. When the patient undergoes hemodialysis, the inlet pump 2 and the outlet pump 3 are started at the same time. The inlet pump 2 injects the patient's blood into the working cylinder 1. Then, the suction force generated by the inlet pump 2 is used to input the blood in the working cylinder 1 into the patient's body. In this process, the blood can be filtered multiple times by the setting of the two filter plates 41, thereby improving the dialysis effect of the patient. The spring 42, the sliding plate 43, and the circulation component 44 for circulating the blood;

[0037] There are two filter plates 41, the outer wall of the filter plate 41 is fixedly connected to the inner wall of the working cylinder 1, the springs 42 are arranged in two groups, a group of springs 42 is arranged with four, the top of the spring 42 is fixedly connected to the bottom of the filter plate 41, and there are two sliding plates 43. The top of the sliding plate 43 is fixedly connected to the bottom of the spring 42, and the outer wall of the sliding plate 43 is slidably connected to the inner wall of the working cylinder 1.

[0038] The circulation assembly 44 includes a fixing ring 441 fixedly connected to the bottom of the filter plate 41 . Four rotating rods 442 are rotatably connected to the outer wall of the fixing ring 441 . One end of the rotating rod 442 away from the fixing ring 441 is rotatably connected to a limiting rod 443 .

[0039] Four limiting grooves 444 are respectively opened around the top of the sliding plate 43, and the bottom outer wall of the limiting rod 443 is slidably connected to the inner wall of the limiting groove 444. Four impact rods 445 are fixedly connected around the top of the sliding plate 43 near the spring 42.

[0040] A rotating assembly 45 is provided on the top of the sliding plate 43. When the sliding plate 43 slides down, the sliding plate 43 drives the circulation assembly 44 and the cross rod 453 in the rotating assembly 45 to descend. Limited by the cross rod 453, the cross rod 453 slides up and down along the inner wall of the rotating ring 454, thereby limiting the lifting and lowering of the sliding plate 43, preventing the position of the sliding plate 43 from shifting during the lifting and lowering process, and improving the stability of the operation of the sliding plate 43. The rotating assembly 45 includes a rotating plate 451 rotatably connected to the center of the top of the sliding plate 43, and four arc holes 452 are respectively opened around the top of the rotating plate 451.

[0041] The outer wall of one end of the limiting rod 443 is slidably connected to the inner wall of the arc hole 452 , a cross rod 453 is fixedly connected to the top center of the rotating plate 451 , and a rotating ring 454 is rotatably connected to the inner wall of the filter plate 41 .

[0042] The inner wall of the rotating ring 454 is arranged in a cross slot, the outer wall of the bottom end of the rotating ring 454 is rotatably connected to the inner wall of the fixed ring 441, the outer wall of one end of the cross rod 453 is slidably connected to the inner wall of the rotating ring 454, and the outer wall of one end of the cross rod 453 close to the rotating ring 454 is slidably connected with a cross sleeve block 455.

[0043] Slide blocks 456 are fixedly connected to both sides of the bottom of the cross sleeve 455, and an annular groove 457 is opened at the top center of the filter plate 41. The outer wall of the slide block 456 is slidably connected to the inner wall of the annular groove 457. When the cross rod 453 rotates, the setting of the rotating ring 454 can prevent the cross rod 453 from contacting the filter plate 41 during rotation, thereby improving the stability of the rotation of the cross rod 453. Because the cross rod 453 drives the cross sleeve 455 to rotate, the cross sleeve 455 drives the slide block 456 to rotate, and the slide block 456 rotates inside the annular groove 457, thereby preventing the cross sleeve 455 from moving up and down on the outer wall of the cross rod 453, thereby improving the stability of the operation of the cross sleeve 455.

[0044] A cleaning assembly 46 is provided on the top of the cross sleeve block 455. When the sliding plate 43 gradually moves away from the filter plate 41, the rotating rod 442 will rotate slightly around the fixing ring 441 on the filter plate 41. The rotating rod 442 is limited by the limiting groove 444, and the limiting rod 443 drives the limiting rod 443 to slide along the inner wall of the limiting groove 444. The limiting rod 443 is set by the arc hole 452 on the top of the rotating plate 451. During the movement of the limiting rod 443, the rotating plate 451 rotates along the top center of the sliding plate 43. The rotating plate 451 drives the arc hole 452 to rotate, and the arc hole 452 drives the cross sleeve block 455 to rotate. The cross sleeve block 455 drives the bent rod 461 to rotate, and the bent rod 461 drives the heating shell 462 to rotate. The piston plate 463 is driven to rotate, and the piston plate 463 drives the conical rod 465 to rotate. Affected by the setting of the return spring 464, when the bottom end of the conical rod 465 is docked with the filter hole of the filter plate 41, the conical rod 465 will slide along the inner wall of the filter hole of the filter plate 41 to prevent impurities in the blood from being stuck in the filter hole of the filter plate 41, thereby improving the blood circulation effect and the dialysis effect of the patient. The cleaning component 46 includes four bent rods 461 fixedly connected to the top of the cross sleeve block 455, and the end of the bent rod 461 away from the cross sleeve block 455 is fixedly connected to the heating shell 462, and the bottom end of the inner wall of the heating shell 462 is slidably connected to the piston plate 463, and the top two sides of the piston plate 463 are respectively fixedly connected to the return springs 464.

[0045] The top of the return spring 464 is fixedly connected to the top of the inner wall of the heating shell 462, and the bottom of the piston plate 463 is fixedly connected with a plurality of conical rods 465. The outer wall of one end of the conical rod 465 passes through the heating shell 462 and extends to the outside of the heating shell 462. The outer wall of the bottom end of the conical rod 465 contacts the filter hole of the filter plate 41.

[0046] In Example 2, a heating component 47 is provided on the inner wall of the heating shell 462. The heating component 47 includes a heater 471 fixedly connected to the top of the inner wall of the heating shell 462. The two sides of the heating shell 462 are respectively connected with a bend pipe 472. The end of the bend pipe 472 away from the heating shell 462 is connected with an exhaust hopper 473. The bottom of the exhaust hopper 473 is contacted with the top of the filter plate 41. When the cross sleeve 455 drives the bent rod 461 to continue to rotate, the bottom end of the conical rod 465 no longer docks with the filter hole of the filter plate 41, and is subjected to the reaction force of the filter plate 41, so that the conical rod 465 is brought The movable piston plate 463 slides upward inside the heating shell 462. The setting of the heater 471 can heat the air flow inside the heating shell 462. When the piston plate 463 moves upward, the hot air flow inside the heating shell 462 enters into the inside of the curved pipe 472. The hot air flow enters into the inside of the exhaust hopper 473 through the curved pipe 472. The hot air flow is sprayed toward the top of the filter plate 41 through the exhaust hopper 473 to heat the blood, prevent the blood from condensing after flowing into the working cylinder 1, thereby improving the blood circulation effect and further improving the patient's dialysis effect.

[0047] During use, when the patient is undergoing hemodialysis, the inlet pump 2 and the outlet pump 3 are started at the same time, and the inlet pump 2 injects the patient's blood into the interior of the working cylinder 1, and then the suction force generated by the inlet pump 2 is used to input the blood inside the working cylinder 1 into the patient's body. In this process, the blood can be filtered multiple times by the setting of the two filter plates 41, thereby improving the dialysis effect of the patient. When the blood enters the interior of the working cylinder 1, the sliding plate 43 slides inside the working cylinder 1, which can block the blood and prevent the blood from circulating too fast. The process of blood circulating inside the working cylinder 1 can make the sliding plate 43 The plate 43 slides down inside the working cylinder 1. When the sliding plate 43 moves to an area with a large radius inside the working cylinder 1, blood can circulate, thereby performing dialysis on the patient. When the sliding plate 43 slides down, the sliding plate 43 drives the cross rod 453 in the circulation component 44 and the rotating component 45 to descend. Limited by the cross rod 453, the cross rod 453 slides up and down along the inner wall of the rotating ring 454, thereby limiting the lifting and lowering of the sliding plate 43, preventing the position of the sliding plate 43 from shifting during the lifting and lowering process, and improving the stability of the operation of the sliding plate 43.

[0048] When the sliding plate 43 gradually moves away from the filter plate 41, the rotating rod 442 will rotate slightly around the fixing ring 441 on the filter plate 41, and is limited by the limiting groove 444. The rotating rod 442 drives the limiting rod 443 to slide along the inner wall of the limiting groove 444. Affected by the setting of the arc hole 452 at the top of the rotating plate 451, the limiting rod 443 causes the rotating plate 451 to rotate along the top center of the sliding plate 43 during the movement. The rotating plate 451 drives the arc hole 452 to rotate, and the arc hole 452 drives the cross sleeve block 455 to rotate. The cross sleeve block 455 drives the bent rod 461 to rotate, and the bent rod 461 drives the heating shell 462 to rotate. The heating shell 462 drives the piston plate 463 to rotate, and the piston plate 463 drives the conical rod 465 to rotate, which is affected by the return spring 464. The arrangement is such that when the bottom end of the conical rod 465 is docked with the filter holes of the filter plate 41, the conical rod 465 will slide along the inner wall of the filter holes of the filter plate 41 to prevent impurities in the blood from being stuck in the filter holes of the filter plate 41, thereby improving the blood circulation effect and indirectly improving the dialysis effect of the patient. When the cross rod 453 rotates, the rotating ring 454 is arranged to prevent the cross rod 453 from contacting the filter plate 41 during rotation, thereby improving the rotation stability of the cross rod 453. Moreover, because the cross rod 453 drives the cross sleeve block 455 to rotate, the cross sleeve block 455 drives the slider 456 to rotate, and the slider 456 rotates inside the annular groove 457, thereby preventing the cross sleeve block 455 from moving up and down on the outer wall of the cross rod 453, thereby improving the operation stability of the cross sleeve block 455.

[0049] When the cross sleeve 455 drives the bent rod 461 to continue to rotate, the bottom end of the conical rod 465 no longer docks with the filter hole of the filter plate 41. Due to the reaction force of the filter plate 41, the conical rod 465 drives the piston plate 463 to slide up inside the heating shell 462. The setting of the heater 471 can heat the air flow inside the heating shell 462. When the piston plate 463 moves upward, the hot air flow inside the heating shell 462 enters the inside of the bent pipe 472, and the hot air flow enters the inside of the exhaust hopper 473 through the bent pipe 472. The hot air flow is sprayed toward the top of the filter plate 41 through the exhaust hopper 473, so as to heat the blood and prevent the blood from condensing after flowing into the working cylinder 1, thereby improving the blood circulation effect and further improving the dialysis effect of the patient.

[0050] When the sliding plate 43 moves to an area where the radius inside the working cylinder 1 is too large, it is elastically stretched by the spring 42, and the spring 42 drives the sliding plate 43 to move upward, and the sliding plate 43 drives the impact rod 445 to move upward. The impact rod 445 will collide with the bottom of the filter plate 41 during the upward movement, causing the filter plate 41 to vibrate slightly, preventing impurities from remaining inside the filter holes of the filter plate 41 when the conical rod 465 slides inside the filter holes of the filter plate 41, thereby further improving the blood circulation effect. After the sliding plate 43 moves upward, it is set by the liquid inlet pump 2 and the liquid outlet pump 3, causing the sliding plate 43 to slide down again, thereby causing the device to reciprocate, thereby improving the device's blood dialysis effect.
