Description

Technical Field

[0001] The present invention relates to the technical field of dialysis disinfection, and particularly relates to an automatic disinfection device for a hemodialysis machine. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining the blood from the body to the outside, passing it through a dialyzer composed of countless hollow fibers. Inside and outside each hollow fiber, blood and an electrolyte solution (dialysate) with a concentration similar to that of the body's fluids exchange substances through the principles of diffusion, ultrafiltration, adsorption, and convection to remove metabolic wastes from the body, maintain electrolyte and acid-base balance; at the same time, remove excess water from the body, and the whole process of returning the purified blood back to the body is called hemodialysis. A hemodialysis machine is a machine for renal replacement therapy, which is a device for maintaining extracorporeal circulation, providing dialysate formulation, achieving ultrafiltration, and ensuring safety. To ensure that the outside of the hemodialysis machine is free of contamination, blood stains, and the number of bacteria does not exceed the national Class III environmental standard, it is necessary to standardize the daily behaviors of relevant personnel for disinfection.

[0003] Currently, the outside of the hemodialysis machine is manually cleaned. The cleaning method is single, and it requires personnel to come into contact with disinfected cleaning items. The disinfection and cleaning operations are inconvenient, time-consuming, and a simple device for spraying disinfectant is used for surface disinfection of the hemodialysis machine. Although it can spray disinfectant alone, subsequent wiping and other cleaning are required after spraying disinfection. The hemodialysis machine lacks a process standard for disinfection operations and completely relies on hospital personnel to complete. Summary of the Invention

[0040] When the wiping plate adjusting cylinder Ⅳ 111 operates, the piston rod of the wiping plate adjusting cylinder Ⅳ 111 can drive the wiping plate adjusting cylinder Ⅴ 112, the box body Ⅱ 113, the rack Ⅱ 114, the gear Ⅱ 115, the gear shaft Ⅱ 116, the wiping plate connecting rod 117, the second motor 118, the wiping plate adjusting cylinder Ⅵ 119 on it, and the first wiping plate 913 or the second wiping plate 923 on the piston rod of the wiping plate adjusting cylinder Ⅵ 119 to move closer to or away from the surface of the dialysis machine as a whole. When the disinfection rack 9 moves to a position close to the pipe clamp (the position of the pipe clamp is collected in advance by the first camera 914 or the second camera 924), the wiping plate adjusting cylinder Ⅴ 112 operates. The piston rod of the wiping plate adjusting cylinder Ⅴ 112 drives the rack Ⅱ 114 to move, and the rack Ⅱ 114 drives the gear Ⅱ 115 to rotate. Through the gear shaft Ⅱ 116, it drives the wiping plate connecting rod 117, the second motor 118 on it, the wiping plate adjusting cylinder Ⅵ 119, and the first wiping plate 913 or the second wiping plate 923 on the piston rod of the wiping plate adjusting cylinder Ⅵ 119 to rotate downward together, so that the first wiping plate 913 or the second wiping plate 923 extends into the pipe clamp to wipe the inner wall of the pipe clamp. The second motor 118 rotates synchronously so that the first wiping plate 913 or the second wiping plate 923 wipes the inner wall of the pipe clamp in the circumferential direction. The piston rod of the wiping plate adjusting cylinder Ⅵ 119 can extend and retract to adjust the wiping radius of the first wiping plate 913 or the second wiping plate 923. When the piston rod of the wiping plate adjusting cylinder Ⅵ 119 extends, it can wipe the pipe clamp with a larger inner hole. When the piston rod of the wiping plate adjusting cylinder Ⅵ 119 retracts, it can wipe the pipe clamp with a smaller inner hole. After the inner wall of the pipe clamp is wiped, the piston rod of the wiping plate adjusting cylinder Ⅵ 119 retracts, so that the first wiping plate 913 or the second wiping plate 923 moves away from the inner wall of the pipe clamp. The piston rod of the wiping plate adjusting cylinder Ⅴ 112 retracts, driving the rack Ⅱ 114 to return. The rack Ⅱ 114 drives the gear Ⅱ 115 to reverse, and then through the gear shaft Ⅱ 116, it drives the wiping plate connecting rod 117, the second motor 118 on it, the wiping plate adjusting cylinder Ⅵ 119, and the first wiping plate 913 or the second wiping plate 923 on the piston rod of the wiping plate adjusting cylinder Ⅵ 119 to rotate upward together, so that the first wiping plate 913 or the second wiping plate 923 returns to the horizontal position.

[0041] The first disinfection nozzle 911 and the second disinfection nozzle 921 are used for disinfection spraying, and the first wiping plate 913 and the second wiping plate 923 are used for wiping and cleaning. The spraying and wiping of the first disinfection mechanism 91 on the right side and the second disinfection mechanism 92 on the left side of the disinfection rack 9 cooperate with each other.

[0042] Among them, the first wiping plate 913 and the second wiping plate 923 are both composed of an L-shaped plate 9131 and an L-shaped wiping soft layer 9132. One straight plate surface of the L-shaped plate 9131 is fixedly connected to the end of the piston rod of the wiping plate adjusting cylinder VI 119. The other straight plate surface of the L-shaped plate 9131 is located outside the wiping plate adjusting cylinder VI 119 and is parallel to the piston rod of the wiping plate adjusting cylinder VI 119. The L-shaped wiping soft layer 9132 is arranged on the outer side surface of the L-shaped plate 9131. As Figure 9 shown, both the first wiping plate 913 and the second wiping plate 923 are L-shaped. When the first wiping plate 913 and the second wiping plate 923 are in the horizontal position, one straight plate surface of the L-shaped first wiping plate 913 and the second wiping plate 923 corresponds to the surface of the dialysis machine. When the first wiping plate 913 and the second wiping plate 923 are in the vertical position, the other straight plate surface of the L-shaped first wiping plate 913 and the second wiping plate 923 corresponds to the surface of the inner wall of the pipe clamp. The L-shaped wiping soft layer 9132 on the surface contacts the surface of the dialysis machine or the surface of the inner wall of the pipe clamp during the wiping process, which not only plays the role of wiping the surface but also can adsorb the excess sprayed disinfectant, and can effectively protect the wiped surface during the wiping process. The first camera 914 and the second camera 924 are both installed on the disinfection rack 9 through the camera adjusting cylinder 12. As Figure 10 shown, the camera adjusting cylinder 12 is vertically arranged on the side wall of the disinfection rack 9. The first camera 914 is installed on the piston rod of the camera adjusting cylinder 12 on the right side of the disinfection rack 9, and the second camera 924 is installed on the piston rod of the camera adjusting cylinder 12 on the left side of the disinfection rack 9. According to the requirements of the data collected by the first camera 914 and the second camera 924, the telescopic distance of the piston rod of the camera adjusting cylinder 12 can be adjusted at any time.

An opening is formed on the side of the installation cavity close to the installation frame 7. The first worm gear 61 and the first worm 62 are meshed. The right end of the turbine shaft cooperating with the first worm gear 61 is fixedly connected to the left side of the installation frame 7. When the first worm gear 61 rotates, it can drive the installation frame 7 to rotate. One end of the first worm 62 is connected to the output shaft of the third motor 63 through a coupling. The third motor 63 is fixedly arranged on the support frame 5. The third motor 63 rotates to drive the first worm 62 to rotate. The first worm 62 drives the first worm gear 61 to rotate. The first worm gear 61 drives the installation frame 7 to rotate on the support frame 5 through the turbine shaft, and is self-locked after rotation through the meshing of the first worm gear 61 and the first worm 62.

[0044] Among them, the flipping mechanism 8 includes an installation box 81, a second worm gear 82, a second worm 83, a fourth motor 84, and a flipping shaft 85. As Figure 5and Figure 11 As shown.

The rotating shaft 85 on the front side of the disinfection rack 9 passes through the mounting rack 7 and is connected to the second worm gear 82. One end of the second worm 83 is connected to the output shaft of the fourth motor 84 through a coupling. The fourth motor 84 is fixedly arranged on the mounting box 81. When the fourth motor 84 rotates, it drives the second worm 83 to rotate. The second worm 83 drives the second worm gear 82 to rotate. The second worm gear 82 drives the disinfection rack 9 to flip on the mounting rack 7 through the rotating shaft 85. After flipping, it is self-locked by the meshing of the second worm gear 82 and the second worm 83.

[0045] Among them, the disinfection supply mechanism 93 includes a first rotary joint 931, a second rotary joint 932, a first connecting pipe 933, a first disinfection pump 934, a second connecting pipe 935, a second disinfection pump 936, a first box 51 and a second box 52, as Figure 4 shown.

The input end of the first disinfection pump 934 is connected to the first box 51 through a pipeline, and the input end of the second disinfection pump 936 is connected to the second box 52 through a pipeline. Both the first connecting pipe 933 and the second connecting pipe 935 are arranged with a hard straight pipe with an L-shaped structure at both ends and a corrugated pipe in the middle, so that the structures at both ends of the first connecting pipe 933 and the second connecting pipe 935 are stable. At the same time, the high flexibility and bending property of the middle corrugated pipe make it adapt to the rotation of the disinfection rack 9. Under the action of the first disinfection pump 934, the disinfectant in the first box 51 is transported to the first disinfection pipe 912 through the first connecting pipe 933, the first rotary joint 931 and the first pipe 937. The first disinfection pipe 912 inputs the disinfectant into the first disinfection nozzle 911 through a telescopic hose for primary spraying disinfection; under the action of the second disinfection pump 936, the disinfectant in the second box 52 is transported to the second disinfection pipe 922 through the second connecting pipe 935, the second rotary joint 932 and the second pipe 938.

The controller collects the acquisition information of the first camera 914 and the second camera 924, and controls the first motor 33, the second motor 118, the third motor 63, the fourth motor 84, the first disinfection pump 934, the second disinfection pump 936, the dryer 95, the detection probe 94, the horizontal cylinder I 42, the nozzle adjustment cylinder II 101, the nozzle adjustment cylinder III 102, the wiping plate adjustment cylinder IV 111, the wiping plate adjustment cylinder V 112, the wiping plate adjustment cylinder VI 119 and the camera adjustment cylinder 12 according to the signals to perform disinfection control on each surface of the hemodialysis machine.

[0047] When using this automatic disinfection device for hemodialysis machines to disinfect a hemodialysis machine, first, the controller is used to control the automatic moving base 1 to move the entire automatic disinfection device for hemodialysis machines to the side of the hemodialysis machine to be disinfected. The disinfection process includes the following steps:

[0048] S1. When it is necessary to disinfect and wipe the top of the hemodialysis machine, start the first motor 33. The first motor 33 drives the threaded rod 32 to rotate. The rotating threaded rod 32 drives the threaded sleeve 34 to move upward, thereby driving the mounting seat 4, the support frame 5, the mounting bracket 7 and the disinfection bracket 9 to move upward together. The piston rod of the horizontal cylinder I 42 extends, driving the support frame 5, the mounting bracket 7 and the disinfection bracket 9 to move together above the top of the hemodialysis machine. Start the fourth motor 84, and drive the disinfection bracket 9 to flip through the flipping mechanism 8, so that the first disinfection mechanism 91 of the disinfection bracket 9 faces the top surface of the disinfection bracket 9. Collect the position signal of the top surface of the disinfection bracket 9 through the first camera 914. Again, adjust the position of the disinfection bracket 9 by controlling the automatic moving base 1, the first motor 33 and the horizontal cylinder I 42, so that the top surface of the hemodialysis machine is completely within the working range of the first disinfection mechanism 91. The piston rods of the lower spray head adjusting cylinder II 101 and the wiping plate adjusting cylinder IV 111 extend, and the first disinfection spray head 911 and the first wiping plate 913 move downward. Under the action of the horizontal cylinder I 42, drive the first disinfection mechanism 91 to move from the right side to the left side of the top surface of the dialysis machine. Under the action of the first disinfection pump 934, the disinfectant liquid in the first tank 51 is transported to the first disinfection pipe 912 through the first connecting pipe 933, the first rotary joint 931 and the first pipe 937. The first disinfection pipe 912 inputs the first disinfection spray head 911 through the telescopic hose to continuously spray disinfect the top surface of the dialysis machine from right to left. Subsequently, the first wiping plate 913 also continuously wipes and cleans the top surface of the dialysis machine from right to left until the first spraying disinfection and wiping cleaning of the top surface of the dialysis machine from right to left are completed. The piston rods of the spray head adjusting cylinder II 101 and the wiping plate adjusting cylinder IV 111 retract, and the first disinfection spray head 911 and the first wiping plate 913 move upward;Restart the first motor 33 again. The first motor 33 drives the threaded rod 32 to rotate in the reverse direction, driving the threaded sleeve 34 to move upward, and then driving the mounting seat 4, the support frame 5, the mounting bracket 7, and the disinfection rack 9 to move upward together. Start the fourth motor 84, and drive the disinfection rack 9 to flip 180° through the flipping mechanism 8, so that the second disinfection mechanism 92 of the disinfection rack 9 faces the top surface of the dialysis machine. Collect the top surface position signal of the hemodialysis machine through the second camera 924. Again, by controlling the first motor 33, move the second disinfection mechanism 92 of the disinfection rack 9 downward to be close to the top surface of the hemodialysis machine. The piston rods of the lower spray head adjustment cylinder II 101 and the wiping plate adjustment cylinder IV 111 extend, and the second disinfection spray head 921 and the second wiping plate 923 move downward. Under the action of the horizontal cylinder I 42, drive the second disinfection mechanism 92 to move from the left side to the right side of the top surface of the dialysis machine. Under the action of the second disinfection pump 936, the disinfectant liquid in the second tank 52 is transported to the second disinfection pipe 922 through the second connecting pipe 935, the second rotary joint 932, and the second pipe 938. The second disinfection pipe 922 inputs the disinfectant through the telescopic hose into the second disinfection spray head 921 to continuously spray and disinfect the top surface of the dialysis machine from left to right. Subsequently, the second wiping plate 923 also continuously wipes and cleans the top surface of the dialysis machine from left to right until the second spraying and disinfection and wiping and cleaning of the top surface of the dialysis machine from left to right are completed. The piston rods of the lower spray head adjustment cylinder II 101 and the wiping plate adjustment cylinder IV 111 retract, and the second disinfection spray head 921 and the first wiping plate 923 move upward. Drive the threaded rod 32 to rotate through the first motor 33 to move the disinfection rack 7 upward, then drive the disinfection rack 9 to rotate through the flipping mechanism 8, so that the dryer 95 faces the top surface of the dialysis machine, and then drive the dryer 95 to dry from right to left on the top surface of the dialysis machine through the horizontal cylinder I 42. Make the detection probe 94 face the top surface of the dialysis machine through the first motor 33 and the flipping mechanism 8, and drive the detection probe 94 to detect from left to right on the top surface of the disinfection rack 7 through the horizontal cylinder I 42.;

[0049] S2. When it is necessary to disinfect and wipe the side of the hemodialysis machine, start the first motor 33. The first motor 33 drives the threaded rod 32 to rotate. The rotating threaded rod 32 drives the threaded sleeve 34 to move upward, thereby driving the mounting seat 4, the support frame 5, the mounting bracket 7 and the disinfection bracket 9 to move upward together, so that the disinfection bracket 9 moves above the side of the hemodialysis machine. Drive the disinfection bracket 9 to flip through the flipping mechanism 8, so that the first disinfection mechanism 91 of the disinfection bracket 9 faces the side of the dialysis machine. Collect the side position signal of the disinfection bracket 9 through the first camera 914. Again, adjust the position of the disinfection bracket 9 by controlling the automatic moving base 1, the first motor 33 and the horizontal cylinder I 42, so that the side of the dialysis machine is completely within the working range of the first disinfection mechanism 91. The piston rods of the spray head adjusting cylinder II 101 and the wiping plate adjusting cylinder IV 111 on the right side extend, and the first disinfection spray head 911 and the first wiping plate 913 move to the right. Under the action of the first motor 33, drive the first disinfection mechanism 91 to move from the top to the bottom of the side of the dialysis machine. The first disinfection spray head 911 continuously sprays disinfectant on the side of the dialysis machine from top to bottom. Subsequently, the first wiping plate 913 also continuously wipes and cleans the side of the dialysis machine from top to bottom until the first spraying disinfection and wiping cleaning of the side of the dialysis machine from top to bottom is completed. The piston rods of the spray head adjusting cylinder II 101 and the wiping plate adjusting cylinder IV 111 on the right side retract, and the first disinfection spray head 911 and the first wiping plate 913 move to the left and close to the disinfection bracket 9. Start the first motor 33 again to move the disinfection bracket 9 upward. Drive the disinfection bracket 9 to flip 180° through the flipping mechanism 8, so that the second disinfection mechanism 92 of the disinfection bracket 9 faces the side of the dialysis machine. Collect the position signal of the side of the hemodialysis machine through the second camera 924. Again, control the first motor 33 to move the second disinfection mechanism 92 of the disinfection bracket 9 to the right and close to the side of the hemodialysis machine. The piston rods of the spray head adjusting cylinder II 101 and the wiping plate adjusting cylinder IV 111 on the right side extend, and the second disinfection spray head 921 and the second wiping plate 923 move to the right. Under the action of the first motor 33, drive the second disinfection mechanism 92 to move from the top to the bottom of the side of the dialysis machine, so that the second disinfection spray head 921 continuously sprays disinfectant on the side of the dialysis machine from top to bottom. Subsequently, the second wiping plate 923 also continuously wipes and cleans the side of the dialysis machine from top to bottom until the second spraying disinfection and wiping cleaning of the side of the dialysis machine from top to bottom is completed. The piston rods of the spray head adjusting cylinder II 101 and the wiping plate adjusting cylinder IV 111 on the right side retract, and the second disinfection spray head 921 and the second wiping plate 923 move to the left. Drive the threaded rod 32 to rotate through the first motor 33 to move the disinfection bracket 7 upward, then drive the disinfection bracket 9 to rotate through the flipping mechanism 8 so that the dryer 95 faces the side of the dialysis machine, and then drive the threaded rod 32 to rotate through the first motor 33 to dry the side of the dialysis machine from top to bottom by the dryer 95. Make the detection probe 94 face the side of the dialysis machine through the first motor 33 and the flipping mechanism 8, and make the detection probe 94 detect from the top to the bottom of the side of the dialysis machine.

[0050] When the disinfection rack 9 moves to a position close to the pipe clamp, the spray head adjusting cylinder III 102 operates to drive the rack I 104 to move rightward. The rack I 104 drives the gear I 105 to rotate, and then drives the spray head connecting rod 107 and the first disinfection spray head 911 or the second disinfection spray head 921 on the spray head connecting rod 107 to rotate downward through the gear shaft I 106, so that the first disinfection spray head 911 or the second disinfection spray head 921 extends into the pipe clamp to spray disinfectant on the inner wall of the pipe clamp. After the spraying on the inner wall of the pipe clamp is completed, the first disinfection spray head 911 or the second disinfection spray head 921 rotates to the horizontal position; then the wiping plate adjusting cylinder V 112 operates, and the piston rod of the wiping plate adjusting cylinder V 112 drives the rack II 114 to move. The rack II 114 drives the gear II 115 to rotate, and drives the wiping plate connecting rod 117, the second motor 118 thereon, the wiping plate adjusting cylinder VI 119 and the first wiping plate 913 or the second wiping plate 923 on the piston rod of the wiping plate adjusting cylinder VI 119 to rotate downward together through the gear shaft II 116, so that the first wiping plate 913 or the second wiping plate 923 extends into the pipe clamp to wipe the inner wall of the pipe clamp. The second motor 118 rotates synchronously so that the first wiping plate 913 or the second wiping plate 923 wipes the inner wall of the pipe clamp in the circumferential direction. After the wiping of the inner wall of the pipe clamp is completed, the piston rod of the wiping plate adjusting cylinder VI 119 retracts, so that the first wiping plate 913 or the second wiping plate 923 moves away from the inner wall of the pipe clamp, and the piston rod of the wiping plate adjusting cylinder V 112 retracts, so that the first wiping plate 913 or the second wiping plate 923 rotates to the horizontal position.

[0051] When there is an inclined surface on the side of the hemodialysis machine, in order to accurately spray disinfectant and wipe and clean the inclined surface, the third motor 63 is started to drive the mounting rack 7 and the disinfection rack 9 on the mounting rack 7 to rotate together, so that the disinfection rack 9 is inclined and parallel to the inclined surface on the side of the dialysis machine, so that the first disinfection spray head 911 or the second disinfection spray head 921, the first wiping plate 913 or the second wiping plate 923 can spray disinfectant and wipe and clean the inclined surface on the side of the dialysis machine.

[0052] The present invention can achieve the lifting and moving of the disinfection rack 9 through the first motor 33, the horizontal movement of the disinfection rack 9 through the horizontal cylinder I 42, the flipping of the disinfection rack 9 through the fourth motor 84, the rotational adjustment of the disinfection rack 9 through the third motor 63, drive the first disinfection nozzle 911 or the second disinfection nozzle 921 to rotate downward and spray inside the pipe clamp through the nozzle adjustment cylinder III 102, drive the first wiping plate 913 or the second wiping plate 923 to rotate downward and wipe and clean the inner wall of the pipe clamp through the wiping plate adjustment cylinder V 112 and the wiping plate adjustment cylinder VI 119, and each operation always maintains spraying and disinfecting first through the first disinfection nozzle 911 or the second disinfection nozzle 921 and then wiping and cleaning through the first wiping plate 913 or the second wiping plate 923, dry the surface of the hemodialysis machine after wiping and cleaning through the dryer 95, and perform the detection of the disinfection, wiping and cleaning of the surface of the hemodialysis machine through the detection probe 94. Therefore, the disinfection rack 9 in the automatic disinfection device of the hemodialysis machine of the present invention has four working surfaces, namely two disinfection and wiping and cleaning surfaces, one drying surface and one detection surface. Combined with the fact that the disinfection rack 9 can be flipped and adjusted on the mounting rack 7, multiple working surfaces of the disinfection rack 9 can be flipped and switched for the disinfection, wiping and cleaning, drying and detection of each surface of the hemodialysis machine, that is, the device integrates the functions of full-automatic disinfection, wiping and cleaning, drying and detection.
