DETAILED DESCRIPTION

[0017] Clearly, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0018] The embodiments provided by the present application will be described in detail below: As Figures 1 to 8 shown, a hemodialysis concentrate filling device includes a filling device body arranged on one side of a conveying belt, the filling device body includes a frame body 100, a pushing assembly 200 is installed on the frame body 100, a liquid injection assembly 400 is installed at a moving end of the pushing assembly 200, the liquid injection assembly 400 includes a liquid injection pipe 410 extending into a liquid storage barrel and a liquid injection piece 500 detachably installed at an end of the liquid injection pipe 410, the liquid injection piece 500 has a connecting cavity 510 and a dispersion cavity 520 inside, a plurality of inwardly recessed flow guide grooves 530 are arranged at an inner wall of a bottom of the dispersion cavity 520, an end of the flow guide groove 530 away from the dispersion cavity 520 is arranged in a downward inclination of 45°, and a through hole is arranged at an outer wall of the liquid injection piece 500 and communicates with the flow guide groove 530; wherein the liquid injection piece 500 is detachably screwed at the end of the liquid injection pipe 410, so as to facilitate replacement and maintenance of the liquid injection piece 500.

[0019] A groove 540 is arranged at a bottom wall of the liquid injection piece 500, a recovery pipe 550 is slidably installed at the center of the dispersion cavity 520 and the groove 540, a piston 551 is arranged at a top of the recovery pipe 550 and cooperates with the connecting cavity 510, a collection cap 570 is installed at a bottom of the recovery pipe 550 and is used to form a package of the through hole, a fixing plate 552 is connected to an outer wall of the recovery pipe 550 located in the groove 540, a spring 560 is fixedly installed between a top wall of the fixing plate 552 and a top wall of the groove 540, and the spring 560 is used to provide an elastic force for keeping the collection cap 570 pressed upward.

[0020] The diameter of the dispersion cavity 520 is greater than the diameter of the connecting cavity 510, so that when liquid injection is performed, the piston part 551 is moved downward under the pressure of the electrolyte, at this time, the piston part 551 is located in the dispersion cavity 520, so that the dialysis liquid enters the dispersion cavity 520 through the connecting cavity 510, at the same time, the collection cap 570 is moved downward to remove the package of the through hole, and the dialysis liquid is injected into the inside of the liquid storage barrel through the through hole on the flow guide groove 530.

[0021] It should be noted that the dialysis liquid first enters the connecting cavity 510, then flows into the dispersion cavity 520, and is then divided and guided by the plurality of flow guide grooves 530 to flow out in the form of a plurality of inclined and relatively gentle liquid streams, rather than a concentrated liquid column, so as to reduce the impact force of the liquid on the bottom of the liquid storage barrel and avoid splashing of the liquid to contaminate the liquid injection pipe 410.

[0022] It can be understood that, by setting the collecting cap 570, the excess dialysate at the through hole can be collected after filling, preventing it from dripping to cause pollution or waste and flowing into the subsequent liquid storage barrel, affecting the quality of the dialysate.

[0023] Specifically, when filling the dialysate, the piston 551 moves downward under the action of the generated pressure to make the piston 551 enter the dispersion cavity 520, separate from the bottom of the connecting cavity 510, and at the same time, the collecting cap 570 moves downward to expose the through hole, so that the filling can be performed. After the filling is completed, the pressure of the dialysate disappears, and the piston 551 is pushed back upward under the restoring force of the spring 560 to make the piston 551 cooperate with the connecting cavity 510 again, preventing the liquid in the filling pipe 410 from continuing to be discharged, and at the same time, the collecting cap 570 is reset to rewrap the through hole and collect the small amount of residual liquid seeping from the flow guide groove 530 and the through hole in the collecting cap 570, avoiding the risk of the residual liquid dripping onto the next liquid storage barrel, the ground or the equipment in the subsequent filling process.

[0024] The whole anti-dripping process is automatically completed by the mechanical structure without manual intervention, improving the automation level and the reliability of the operation of the equipment.

[0025] As shown in Figures 5 to 8 The recycling pipe 550 has a cavity inside, the outer wall of the recycling pipe 550 is provided with a plurality of recycling holes 553 communicating with the cavity and the collecting cap 570, the plurality of recycling holes 553 are arranged at equal intervals along the circumference of the recycling pipe 550, the cavity is provided with an adsorption assembly 700, the adsorption assembly 700 includes a recycling box 710 arranged at the frame body 100 and a connecting pipe 740 threadedly arranged at the inner wall of the filling pipe 410, the recycling box 710 is internally provided with an adsorption device 720, the adsorption device 720 is used to form negative pressure in the recycling pipe 550, the adsorption device 720 is used to recycle the dialysate in the collecting cap 570 through the connecting pipe 740 and the recycling pipe 550, avoiding secondary pollution caused by long time in the collecting cap 570, the adsorption device 720 can be a vacuum pump, a second hose 730 is arranged at the input end of the adsorption device 720, one end of the connecting pipe 740 is slidingly inserted into the recycling pipe 550, and the other end of the connecting pipe 740 is in communication with the second hose 730.

[0026] It should be noted that the connecting pipe 740 is slidingly inserted into the recycling pipe 550, ensuring that the connecting pipe 740 and the recycling pipe 550 always remain in communication when the recycling pipe 550 moves up and down.

[0027] Specifically, when the filling is completed, the collection cap 570 is wrapped around the end of the liquid injection piece 500 under the action of the spring 560, and the adsorption device 720 is started to actively absorb the residual liquid collected in the collection cap 570. The absorbed residual liquid is transported to the recovery tank 710 at the frame 100 through the second hose 730 for unified collection and treatment, avoiding the residual liquid remaining in the collection cap 570, immediately absorbing the residual liquid, fundamentally cutting off the possibility of microorganisms breeding in the collection cap 570, further improving the filling quality of the dialysis liquid, reducing the risk of cross contamination, and improving the stability and efficiency of continuous operation of the equipment.

[0028] As shown in Figures 1 to 8 The recovery pipe 550 is internally connected with the air pipe 580 coaxially arranged with the recovery pipe 550, the collection cap 570 has an air cavity 571 inside, the air pipe 580 has an air channel communicating with the air cavity 571 inside, and a plurality of one-way valves 572 are installed on the inner wall of the collection cap 570, and the output end of the one-way valve 572 is arranged in a downward inclined manner.

[0029] The air channel is connected with the purge assembly 600, the purge assembly 600 includes the air blower 610 arranged at the frame 100 and the second air pipe 630 threadedly arranged at the inner wall of the connecting pipe 740, the air blower 610 is provided with the first hose 620 at the output end, one end of the second air pipe 630 is slidingly inserted into the first pipe 580, and the other end of the second air pipe 630 is in communication with the first hose 620.

[0030] It should be noted that one end of the second air pipe 630 is slidingly inserted into the first pipe 580, which ensures that the second air pipe 630 and the first pipe 580 are always in communication when the recovery pipe 550 moves up and down.

[0031] Specifically, the air blower 610 on the frame 100 discharges air into the air channel in the first air pipe 580 through the first hose 620 and the second air pipe 630, and finally into the air cavity 571 in the collection cap 570. The gas accumulates in the air cavity 571 and is sprayed out at a downward inclined angle through the plurality of one-way valves 572, ensuring that the gas can accurately blow the key parts most likely to have residual dialysis liquid, such as the inner wall of the collection cap 570, the bottom outer wall of the liquid injection piece 500, and the outlet of the flow guide groove 530, so that the dialysis liquid is collected at the bottom of the collection cap 570.

[0032] In addition, the gas can be sucked into the recovery pipe 550 and the connecting pipe 740 by the adsorption assembly 700 to blow the inner wall of the recovery pipe 550 and the connecting pipe 740, preventing the dialysis liquid from remaining in the recovery pipe 550, the connecting pipe 740, the collection cap 570, and the through hole.

[0033] It can be understood that the one-way valve 572 is provided to prevent the dialysis liquid from flowing back into the air cavity 571 of the collection cap 570 during filling or recovery of residual liquid.

[0034] As Figure 3 shown, the frame 100 is provided with a through slot, and the inner wall of the through slot is provided with a sliding groove 210 on both sides. The pushing assembly 200 comprises a sliding seat 220 slidingly arranged in the sliding groove 210. The side wall of the sliding seat 220 is provided with a horizontally arranged mounting portion. The liquid injection assembly 400 is mounted on the mounting portion. The pushing device 230 is mounted between the frame 100 and the sliding seat 220. The pushing device 230 is used to push the sliding seat 220 to move in a direction perpendicular to the external conveying belt, so as to realize the vertical alignment of the liquid injection assembly 400 and the liquid storage barrel. The pushing device 230 can be a pneumatic cylinder or a hydraulic cylinder.

[0035] It should be noted that, through the arrangement of the pushing device 230, when the external conveying belt transports the empty liquid storage barrel to the filling station, the pushing device 230 moves the liquid injection assembly 400 to the position directly above the liquid storage barrel to be filled, so that the liquid injection assembly 400 is vertically aligned with the liquid storage barrel, thereby facilitating the vertical alignment of the liquid storage barrels at different positions or different specifications.

[0036] As Figures 1 to 8 shown, the frame 100 is provided with a through slot, and the inner wall of the through slot is provided with a sliding groove 210 on both sides. The pushing assembly 200 comprises a sliding seat 220 slidingly arranged in the sliding groove 210. The side wall of the sliding seat 220 is provided with a horizontally arranged mounting portion. The liquid injection assembly 400 is mounted on the mounting portion. The pushing device 230 is mounted between the frame 100 and the sliding seat 220. The pushing device 230 is used to push the sliding seat 220 to move in a direction perpendicular to the external conveying belt, so as to realize the vertical alignment of the liquid injection assembly 400 and the liquid storage barrel. The pushing device 230 can be a pneumatic cylinder or a hydraulic cylinder.

[0037] The frame 100 is provided with a circular hole, and the top of the bottom plate 310 is provided with a guide rod 330 matched with the circular hole. The guide rod 330 passes through the top of the circular hole and is provided with a limiting block, thereby improving the stability of the vertical lifting of the frame 100.

[0038] It should be noted that, through the arrangement of the pushing device 230, when the external conveying belt transports the empty liquid storage barrel to the filling station, the pushing device 230 moves the liquid injection assembly 400 to the position directly above the liquid storage barrel to be filled, so that the liquid injection assembly 400 is vertically aligned with the liquid storage barrel, thereby facilitating the vertical alignment of the liquid storage barrels at different positions or different specifications.

[0039] Specifically, when the conveying belt transports the empty liquid storage barrel to the filling station, the pushing device 230 moves the liquid injection assembly 400 to the position directly above the liquid storage barrel to be filled, so that the liquid injection assembly 400 is vertically aligned with the liquid storage barrel. Then, the lifting device 320 drives the liquid injection assembly 400 to descend and extend into the barrel for filling of the dialysis liquid. At the time of filling, under the action of the pressure of the dialysate, the piston 551 overcomes the elastic force of the spring 560 and moves downward, so that the piston 551 enters the dispersion cavity 520, is separated from the bottom of the connecting cavity 510, and at the same time, the collecting cap 570 moves downward, and the through hole is exposed, which guides the dialysate in the dispersion cavity 520 to the inner wall of the storage barrel, and then to the inside of the storage barrel, after the filling is completed, the pressure of the dialysate disappears, under the action of the restoring force of the spring 560, the piston 551 is pushed upward, so that the piston 551 cooperates with the connecting cavity 510 again, preventing the liquid in the liquid injection pipe 410 from continuing to be discharged, at the same time, the collecting cap 570 is reset, and the through hole is wrapped again, at this time, the adsorption device 720 and the air blower 610 are started, and the residual liquid collected in the collecting cap 570 is actively absorbed, the residual liquid absorbed is transported to the recovery tank 710 at the frame body 100 through the second hose 730, at the same time, the air blower 610 discharges the gas into the air passage in the first air pipe 580 through the first hose 620 and the second air pipe 630, and finally into the air cavity 571 in the collecting cap 570, the gas accumulates in the air cavity 571, and drives the plurality of one-way valves 572 to be sprayed at a downwardly inclined angle, and the inner wall of the collecting cap 570, the bottom outer wall of the liquid injection piece 500 and the through hole are blown. When the residual liquid in the collecting cap 570 is adsorbed and recovered, the gas is sucked into the recovery pipe 550 and the connecting pipe 740 through the adsorption device 720, and the inner wall of the recovery pipe 550 and the connecting pipe 740 is blown.
