Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hemodialysis, and in particular to a hemoperfusion device supporting device and a hemoperfusion combined hemodialysis dialysis machine thereof. Background Art
[0002] Hemoperfusion devices are mainly used for the adsorption of medium-molecular toxins in acute and chronic drug poisoning and uremia, and the adsorption of pathogenic factors in the fields of liver disease and immunity. The main application modes include single hemoperfusion mode, hemodialysis combined with hemoperfusion mode, and plasma separation and adsorption mode. Hemodialysis combined with hemoperfusion mode makes up for the deficiency of simple hemodialysis that cannot effectively remove medium- and large-molecular toxins, protein-bound toxins, and various inflammatory mediators. However, the overall structure, connection method, and pre-flushing method of the combined artificial kidney extracorporeal circulation are more complicated than those of simple dialysis, resulting in an increased risk of infection and coagulation in patients.
[0003] When performing hemoperfusion combined with hemodialysis, install the dialyzer on the bracket tube clamp, and then install the perfusion device on another bracket tube clamp, with the venous end of the perfusion device facing upwards, connect the arteriovenous line of the perfusion device, and the venous end of the dialyzer facing upwards, connect the dialysis venous line to the venous end of the dialyzer, manually rotate the bracket, and then connect the dialysis arterial line to the arterial end of the dialyzer, and then manually reverse the bracket to return the venous end of the dialyzer to the top again. Pre-flush the perfusion device, and follow the quick exhaust guide to fully exhaust the air and particles in the perfusion device. Step 1: Manually remove the perfusion device, open the pre-flush liquid, exhaust the air and particles from the arterial end and the column, manually tilt the perfusion device, and the horizontal angle is about 30 to 60 degrees. The other hand holds the exhaust hammer and continuously hits the bottom of the perfusion device; Step 2: Exhaust the venous end, hold it vertically, and exhaust the bubbles. After the perfusion device is vented and particles are removed, the dialyzer is pre-flushed. When the dialyzer is pre-flushed and vented, the pre-flushing liquid enters the dialyzer from the arterial end at the bottom of the dialyzer and is discharged from the venous end at the top, thereby expelling the gas and impurities in the dialyzer membrane. In order to better discharge the gas and impurities in the dialyzer membrane, the operator needs to pat the dialyzer or remove the dialyzer for rubbing. After the gas in the dialyzer membrane is discharged, the bypass interface on the side wall of the dialyzer is connected to the bypass line, and the bracket is manually rotated again to make the arterial end of the dialyzer higher than the venous end. The dialyzer enters the dialyzer from the bypass line at the bottom and is discharged from the bypass line at the top, thereby flushing the outside of the dialyzer membrane. After the pre-washing is completed, the other ends of the dialysis arterial line and the dialysis venous line are connected to the patient's arteriovenous puncture needle, and hemoperfusion dialysis can begin.
[0004] It can be seen from the existing pre-flushing of the perfusion device and dialyzer that the flipping, tilting and patting of the perfusion device and dialyzer are all manual operations. The entire operation needs to be done manually to exhaust the gas and particles in the perfusion device, the impurities in the dialyzer, and the gas inside and outside the dialyzer membrane. This depends entirely on whether the medical staff's operation is standardized and serious. If the operation is sloppy or interrupted in the middle, the gas and particles in the perfusion device, the impurities in the dialyzer, and the gas inside and outside the dialyzer membrane cannot be completely exhausted, and there is a risk of embolism. At the same time, manual flipping, tilting and patting require the hands to contact different parts of the perfusion device, dialyzer and bracket and different time periods, which brings infection risks to the subsequent connection of the human arterial and venous puncture needle connector. When operating, medical staff must first pre-flushed and exhaust the perfusion device, and then pre-flushed and exhaust the dialyzer, which cannot be done synchronously, so the operation time is increased.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The hemoperfusion device support device and its hemoperfusion combined with hemodialysis dialysis machine realize automatic flipping of the perfusion device and dialyzer, automatic tilting of the perfusion device and dialyzer, and automatic vibration of the perfusion device and dialyzer, thereby realizing automatic exhaust and impurity removal in the perfusion device and dialyzer, without manual operation. Medical personnel only need to connect the venous end, arterial end and bypass interface, which greatly reduces manual operation, thereby reducing the chance of contact with the instrument and reducing the risk of infection caused by manual operation and subsequent connection of the human arterial and venous puncture needle connector. At the same time, through automatic control, the perfusion device and dialyzer can be pre-flushed to exhaust and remove impurities simultaneously, which not only saves time, but also avoids the risk of embolism caused by the improper operation of medical personnel affecting the impurities in the perfusion device and the dialyzer and the gas inside and outside the dialyzer membrane cannot be completely discharged, greatly reducing the dependence on medical personnel, so that the pre-flushing of the perfusion device and the exhaust of gas and impurities inside and outside the dialyzer membrane are better guaranteed.
[0019] 2. When the blood perfusion combined with hemodialysis is used to pre-flushing exhaust and remove particles from the perfusion device, the piston rods of the left cylinder II and the right cylinder III are retracted a short distance, so that the left sliding sleeve leaves the left clamping plate, the right sliding sleeve leaves the right clamping plate, and the left and right pull ropes are in a relaxed state, so that the perfusion device is suspended on the U-shaped frame by the left spring and the right spring. The left vibration motor and the right vibration motor of the perfusion device are turned on, and the pre-flushing liquid is injected, and the motor on the perfusion device bracket is rotated to drive the perfusion device bracket to tilt forward or backward, so that the perfusion device is in multi-dimensional vibration, so that the gas in the perfusion device, including the gas and particles between the solid adsorbents in the perfusion device, on the solid adsorbents and on the inner wall of the perfusion device, moves upward in multiple dimensions and is discharged from the top of the perfusion device, so that the gas and particles in the perfusion device can be discharged efficiently and completely in a short time.
[0020] 3. When the hemoperfusion combined with hemodialysis is used to pre-flushed the dialyzer for exhaust and impurities, the dialyzer is clamped between the left support plate and the right support plate, and the controller controls the piston rod of cylinder IV to extend, and the piston rod drives the guide cylinder to move toward the middle, thereby driving the vibration spring and the vibration clamp plate to approach the dialyzer together, and the elastic pads on the inner side of the left and right vibration clamp plates are pressed on the left and right sides of the dialyzer and clamp the dialyzer, and the dialyzer vibration motors on the left and right sides are turned on. At the same time, the dialyzer bracket rotates the motor to drive the dialyzer to tilt, and the inclination angle sensor on the inner elastic pad of the vibration clamp plate is used to transmit the dialyzer to the dialyzer. The sensor detects the tilt angle of the dialyzer, which is convenient for accurately controlling the tilt angle of the dialyzer; when the priming liquid passes through the dialyzer, the dialyzer vibration motors on the left support plate and the right support plate are at one high and one low, and under the synergistic effect of the dialyzer support rotating motor driving the dialyzer to tilt, the dialyzer moves in multiple dimensions. Driven by the priming liquid, the air and impurities attached to the inner wall of the dialyzer and the fiber membrane in the dialyzer can be separated and discharged as soon as possible, and after the dialyzer is tilted, it is also beneficial for the gas and impurities attached to the top of the dialyzer to be discharged through the venous end or the bypass pipeline.

At the same time, the piston rod of the right cylinder III 71 extends to drive the right sliding sleeve 73 to approach the right outer wall of the right clamping plate 75 and fit it. The arc-shaped end 78 can better fit with the left outer wall of the left clamping plate 67 and the right outer wall of the right clamping plate 75, so that the perfusion device 10 can be better clamped and the clamping is more stable.
[0043] When the irrigation device support 6 is used, the piston rod of the left cylinder II 63 retracts to drive the left sliding sleeve 65 to move to the left, and the left clamping plate 67 is driven to move to the left together through the left pull rope 68, and the left spring 66 is compressed.

The left vibration motor 69 and the right vibration motor 77 of the cartridge are turned on. Under the injection of the priming liquid, the motor 5 on the cartridge support drives the cartridge support 6 to tilt forward or backward, so that the cartridge 10 is in multi-dimensional vibration, so that the gas in the cartridge 10, including the gas between the solid adsorbents in the cartridge 10, on the solid adsorbents and on the inner wall of the cartridge 10, moves upward in multiple dimensions and is discharged from the top of the cartridge 10, so that the gas in the cartridge 10 can be discharged efficiently and completely in a short time.

When flipping, the venous end of the dialyzer 11 can be flipped to the bottom, and the arterial end of the dialyzer 11 can be flipped to the top, which is convenient for arteriovenous catheter connection. When the vibration mechanism 84 clamps the dialyzer 11, the vibration mechanism 84 is turned on, and under the synergistic effect of the dialyzer support rotating motor 5 driving the dialyzer 11 to tilt, the air and impurities in the dialyzer 11 can be completely and effectively exhausted.
[0045] The vibration mechanism 84 includes a left vibration mechanism installed at the middle of the inner side of the left support plate 81 and a right vibration mechanism installed at the middle of the inner side of the right support plate 82.

When the dialyzer 11 is placed between the left support plate 81 and the right support plate 82, the piston rods of the cylinder IV 841 on the left support plate 81 and the right support plate 82 extend, driving the guide cylinder 842 to move toward the middle, thereby driving the vibration spring 843 and the vibration clamping plate 844 to approach the dialyzer 11 together, and the vibration clamping plates 844 on the left and right sides are pressed on the left and right sides of the dialyzer 11 and clamp the dialyzer 11. At this time, the dialyzer vibration motors 845 on the left and right sides are turned on. At the same time, the dialyzer support rotation motor 5 drives the dialyzer 11 to tilt, and the dialyzer 11 is tilted. When the flushing liquid passes through the dialyzer 11, the dialyzer vibration motors 845 on the left support plate 81 and the right support plate 82 are in a high and low position, and the dialyzer support rotating motor 5 rotates to drive the dialyzer 11 to tilt, so that the dialyzer 11 moves in multiple dimensions. Driven by the pre-flushing liquid, the air and impurities attached to the inner wall of the dialyzer 11 and the fibers in the dialyzer 11 can be separated and discharged as soon as possible.

Fig. 9 and Fig.10As shown, a clamping cylinder V 831 is installed in each cylinder V mounting hole 833, and the piston rod of the clamping cylinder V 831 faces inward (that is, the piston rod of the clamping cylinder V 831 faces the middle part between the left support plate 81 and the right support plate 82), and the piston rod of the clamping cylinder V 831 is fixedly connected with a clamping plate 832, and the clamping plate 832 is an arc-shaped plate, and the clamping plate 832 on the inner side of the left support plate 81 close to the upper side and the clamping plate 832 on the inner side of the right support plate 82 close to the upper side form a group of dialyzer clamping plates, and the clamping plate 832 on the inner side of the left support plate 81 close to the lower side and the clamping plate 832 on the inner side of the right support plate 82 close to the lower side form another group of dialyzer clamping plates. Before the priming begins, when the dialyzer 11 needs to be turned or tilted, the piston rods of the clamping cylinders V831 on the left support plate 81 and the right support plate 82 extend to drive the clamping plates 832 on the left and right sides to approach the dialyzer 11 and clamp the dialyzer 11. The dialyzer 11 is clamped more stably by the upper and lower sets of dialyzer clamping plates. When the dialyzer 11 is in the formal dialysis, the dialyzer 11 is also clamped by the two sets of dialyzer clamping plates.

At least two inner grooves 87 are provided near the inner side of the rear end of the left support plate 81, and outer convex rotating arms 88 are provided near the inner side of the rear end of the right support plate 82, which are equal to the number of the inner grooves 87 and cooperate with each other. In this embodiment, the number of the inner grooves 87 and the outer convex rotating arms 88 are both two. Through holes Ⅰ89 are provided on the rear end of the left support plate 81 and the outer convex rotating arms 88. The outer convex rotating arms 88 on the rear end of the right support plate 82 are located in the inner groove 87 on the rear end of the corresponding left support plate 81. The positioning shaft 85 passes through the through hole Ⅰ89 on the rear end of the left support plate 81 and the through hole Ⅰ89 on the outer convex rotating arms 88. Torque springs 86 are sleeved on the positioning shaft 85 in each inner groove 87 and at both ends of the corresponding outer convex rotating arms 88. One end of the torque spring 86 is fixedly connected to the side wall of the corresponding inner groove 87, and the other end of the torque spring 86 is fixedly connected to the corresponding outer convex rotating arm 88. When the torque spring 86 is in a natural state, the front end snap-in ends of the left support plate 81 and the right support plate 82 are close to each other. When the dialyzer 11 is installed on the dialyzer support 8, the dialyzer 11 is pressed against the front end snap-in ends of the left support plate 81 and the right support plate 82. After the snap-in end on the right side is pressed, the right support plate 82 rotates to the right rear side around the positioning shaft 85, and the torque spring 86 is deformed. After the dialyzer 11 is placed between the left support plate 81 and the right support plate 82, the restoring force of the torque spring 86 drives the left support plate 81 and the right support plate 82 close to the dialyzer 11, and the clamping mechanism 83 or the vibration mechanism 84 clamps the dialyzer 11.

When the left clamping plate 67 and the right clamping plate 75 clamp the cartridge 10, and the clamping plate 832 or the vibrating clamping plate 844 clamps the dialyzer 11, the pressure sensor 91 can monitor the clamping force to prevent the cartridge 10 and the dialyzer 11 from being damaged by excessive clamping force, and to prevent the cartridge 10 from slipping off the left clamping plate 67 and the right clamping plate 75 due to too light clamping force, and to prevent the dialyzer 11 from slipping off the left and right vibrating clamping plates 844 or the left and right clamping plates 832 due to too light clamping force. The tilt sensor 92 can monitor the tilt angle of the cartridge 10 and the dialyzer 11, so that the cartridge 10 and the dialyzer 11 are tilted to the optimal position, which is beneficial for the gas and impurities attached to the top of the cartridge 10 and the dialyzer 11 to move upward and discharge further, and also makes the venous end or arterial end of the cartridge 10 and the dialyzer 11 in the optimal position for discharge.

The cylinder VI 151 is controlled by the controller in the dialyzer body 12. Before the dialysis pre-flushing machine is installed, the blood perfusion device support device needs to be installed on the dialyzer body 12. The controller in the dialyzer body 12 controls the piston rod of the cylinder VI 151 to retract, and pulls the locking pin 154 to move into the mounting hole 14 through the locking rope 156. The guide locking sleeve 153 slides toward one side of the cylinder VI 151, and the locking spring 155 is compressed.

Fig.13 and Fig.17The distance between the support center formed by the left support plate 81 and the right support plate 82 and the support rod 18 is greater than half the length of the dialyzer 11, which can prevent the ends of the cartridge 10 and the dialyzer 11 from contacting the support rod 18 and affecting the flipping of the cartridge 10 and the dialyzer 11 when the cartridge support rotating motor 4 drives the cartridge 10 to flip and the dialyzer support rotating motor 5 drives the dialyzer 11 to flip. The piston rod of the right telescopic cylinder I2, the power output shafts of the cartridge support rotating motor 4 and the dialyzer support rotating motor 5 are all facing the right side of the dialyzer body 12.

[0055] Installation of the cartridge 10: The cartridge 10 is placed between the left clamping plate 67 and the right clamping plate 75, and the piston rods of the left cylinder II 63 and the right cylinder III 71 are extended. The piston rod of the left cylinder II 63 extends to drive the left sliding sleeve 65 to drive the left clamping plate 67 to press on the left side of the cartridge 10, and the piston rod of the right cylinder III 71 extends to drive the right sliding sleeve 73 to drive the right clamping plate 75 to press on the right side of the cartridge 10. The venous end of the cartridge 10 faces upward, and the venous line is connected to the venous end of the cartridge 10.

The left clamping plate 67 presses the left side of the irrigator 10 by the driving force of the left spring 66, and the right clamping plate 75 presses the right side of the irrigator 10 by the driving force of the right spring 74, so that the irrigator 10 is suspended on the U-shaped frame 61 by the left spring 66 and the right spring 74. The left vibration motor 69 and the right vibration motor 77 of the cartridge are turned on, and the priming liquid is poured in. The motor 5 on the cartridge holder drives the cartridge holder 6 to tilt forward or backward, so that the cartridge 10 is in multi-dimensional vibration, so that the gas in the cartridge 10, including the gas and impurities between the solid adsorbents in the cartridge 10, on the solid adsorbents and on the inner wall of the cartridge 10, moves upward in multiple dimensions and is discharged from the top of the cartridge 10, so that the gas and impurities in the cartridge 10 can be discharged efficiently and completely in a short time.
[0058] Pre-flushing the dialyzer 11: the controller controls the piston rod of the cylinder IV 841 to extend, and the piston rod drives the guide cylinder 842 to move toward the middle, thereby driving the vibration spring 843 and the vibration clamp 844 to move closer together, and the rubber pads 90 on the inner side of the left and right vibration clamps 844 are pressed on the left and right sides of the dialyzer 11 and clamp the dialyzer 11. At this time, the controller controls the piston rod of the clamping cylinder V 831 to retract, driving the clamping plate 832 and the rubber pad 90 on its inner side away from the dialyzer 11, and releasing the constraint of the clamping mechanism 83 on the dialyzer 11. The dialyzer vibration motors 845 on the left and right sides are turned on. At the same time, the dialyzer support rotating motor 5 drives the dialyzer 11 to tilt. The tilt angle of the dialyzer 11 is detected by the inclination sensor 92 on the rubber pad 90 on the inner side of the vibration clamp 844, so as to accurately control the tilt angle of the dialyzer 11. When the priming liquid passes through the dialyzer 11, the dialyzer vibration motors 845 of the left support plate 81 and the right support plate 82 are in a high and low position, and the dialyzer support rotating motor 5 rotates to drive the dialyzer 11 to tilt, so that the dialyzer 11 is in a multi-dimensional mixed motion. Driven by the priming liquid, the inner wall of the dialyzer 11 and the fibers in the dialyzer 11 are attached to the dialyzer 11. Air and impurities can be separated and discharged as quickly as possible, and after the dialyzer 11 is tilted, it is also convenient for the gas and impurities attached to the top of the dialyzer 11 to be discharged through the venous end. After the gas and impurities in the dialyzer 11 membrane are discharged, the bypass interface on the dialyzer 11 is connected to the bypass pipeline accordingly, and the controller controls the dialyzer bracket rotation motor 5 to drive the dialyzer 11 to flip, so that the arterial end of the dialyzer 11 is higher than the venous end, and the bypass pipeline is opened to flush the outside of the dialyzer 11 membrane. At the same time, the two dialyzer vibration motors 845 are turned on, and the dialyzer bracket rotation motor 5 drives the dialyzer 11 to swing up and down slightly, so that the gas and impurities outside the dialyzer 11 membrane can be quickly discharged.
[0059] The hemoperfusion combined with hemodialysis dialysis machine realizes automatic flipping of the perfusion device 10 and the dialyzer 11, automatic tilting of the perfusion device 10 and the dialyzer 11, and automatic vibration of the perfusion device 10 and the dialyzer 11, thereby realizing automatic exhaust and impurity removal in the perfusion device 10 and the dialyzer 11, without manual operation, and the medical staff only needs to connect the venous end, the arterial end and the bypass interface, which greatly reduces the manual operation, thereby reducing the probability of contact with the instrument, and reducing the risk of infection caused by the subsequent manual operation of the arteriovenous puncture needle connector of the human body. At the same time, through automatic control, the perfusion device 10 and the dialyzer 11 can be pre-flushed to exhaust and remove impurities synchronously, which not only saves time, but also avoids the risk of embolism caused by the improper operation of the medical staff, which affects the impurities in the perfusion device 10 and the dialyzer and the gas inside and outside the dialyzer membrane cannot be completely exhausted, greatly reducing the dependence on medical staff, so that the exhaustion of gas and impurities in the pre-flushing perfusion device 10 and inside and outside the membrane of the dialyzer 3 is better guaranteed.
