Description

Technical Field

[0001] This utility model relates to the technical field of dialysis fluid preparation equipment, specifically a concentrated dialysis fluid preparation device. Background Technology

[0002] Dialysis treatment requires the use of concentrated dialysate (solution A and solution B). Concentrated dialysate requires equipment to mix reverse osmosis water (solvent) with dialysate powder (solute). The equipment used to prepare concentrated dialysate needs to be sterilized regularly.

[0003] Current technology uses chemical disinfection (the disinfectant is peracetic acid). The process requires manual pouring of a 10-liter, high-concentration disinfectant solution into a mixing tank, followed by the addition of reverse osmosis water for dilution, soaking, and disinfection. The drawbacks are that improper handling can cause the disinfectant to splash and corrode clothing, or even burn the body; furthermore, the disinfectant is volatile and emits a strong, irritating odor when manually poured, which can harm human health. Summary of the Invention

[0004] The purpose of this invention is to provide a concentrated dialysis fluid preparation device that automatically draws disinfectant into a mixing tank by using negative pressure generated by liquid flow, which can effectively prevent the disinfectant from splashing and evaporating during the process of entering the mixing tank, thereby protecting human safety and avoiding harm to human health.

[0005] This utility model is implemented as follows:

[0006] A concentrated dialysis fluid preparation device includes a mixing tank, on which a self-priming disinfection mechanism and a power pump assembly are provided. The self-priming disinfection mechanism is connected to the power pump assembly via a pipe. A stirring assembly is provided inside the mixing tank, and the stirring assembly is connected to the power pump assembly via a pipe. The stirring assembly is also connected to the self-priming disinfection mechanism.

[0007] The self-priming disinfection mechanism includes a self-priming tube connected in series on the output pipe of the power pump assembly. The self-priming tube is connected to the stirring assembly. A spray pipe is fixedly connected to the inner wall of the self-priming tube. The inner diameter of the inlet end of the spray pipe is larger than the inner diameter of the outlet end. The inlet end of the spray pipe is fixedly connected to the inner wall of the self-priming tube. The outlet end of the spray pipe is located in the middle of the cavity of the self-priming tube. A suction branch pipe is fixedly connected to the upper part of the self-priming tube. The suction branch pipe is connected to the self-priming tube, and the outlet end of the suction branch pipe is located close to the outlet end of the spray pipe. The suction branch pipe is connected to a silicone tube for communicating with the disinfectant tank.

[0008] Furthermore, an electric ball valve for controlling the start and stop of disinfectant inhalation is connected between the inhalation branch tube and the silicone tube.

[0009] Furthermore, the stirring assembly includes a shaft tube that communicates with the power pump assembly. The shaft tube is disposed inside the liquid mixing tank and located at the lower part of the liquid mixing tank. Multiple windows are opened on the side of the shaft tube. An inwardly curved nozzle is rotatably connected to the shaft tube, and the nozzle communicates with the shaft tube through the windows.

[0010] Furthermore, the nozzle includes a sleeve rotatably connected to the shaft tube, a side tube fixedly connected to the sleeve, the side tube communicating with the sleeve, the side tube communicating with the shaft tube through the window, and an inwardly bent connecting tube connected to the side tube, the connecting tube being connected to a nozzle.

[0011] Furthermore, multiple side tubes are fixedly connected to the sleeve, and the direction in which two side tubes are symmetrically arranged and connected to the connecting tube is also symmetrical.

[0012] Furthermore, the connecting pipe includes a straight pipe connected to the side pipe, the straight pipe is connected to an inclined pipe, the inclined pipe is connected to an inwardly hooked end pipe, and the end pipe is connected to the nozzle.

[0013] Furthermore, the nozzle is duckbill shaped.

[0014] Furthermore, a limiting ring is fixedly sleeved on the shaft tube, the limiting ring is located below the sleeve, and a plug for limiting the sleeve is provided above the sleeve, the plug being connected to the shaft tube.

[0015] Furthermore, the power pump assembly is disposed on the outer wall of the liquid mixing tank.

[0016] Furthermore, the power pump assembly includes multiple micro water pumps connected in parallel, and all of the multiple micro water pumps in the stirring assembly are connected together, with the self-priming pipe connected to any one of the micro water pumps.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In practical applications, driven by the power pump assembly, the liquid flows rapidly within the self-priming tube. After passing through the nozzle within the tube, the liquid flows in a jet-like manner because the inner diameter of the nozzle's inlet is larger than that of its outlet. This creates a negative pressure between the nozzle outlet and the edge of the self-priming tube's inner cavity. Under atmospheric pressure, the disinfectant in the disinfectant tank is automatically drawn into the self-priming tube through the suction branch pipe at the nozzle outlet and the silicone tube connected to the suction branch pipe. The disinfectant then enters the mixing tank through the pipe connected to the self-priming tube and the stirring assembly. Driven by the power pump assembly, the liquid in the mixing tank is stirred and mixed, achieving self-priming disinfection. This invention automatically draws the disinfectant into the mixing tank using the negative pressure generated by the liquid flow, effectively preventing splashing and evaporation of the disinfectant during its entry into the mixing tank, thus protecting human safety and preventing harm to human health.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please see Figures 1 to 5 A concentrated dialysis fluid preparation device includes a mixing tank 1, on which a self-priming disinfection mechanism and a power pump assembly are provided. The self-priming disinfection mechanism is connected to the power pump assembly through a pipe. A stirring assembly is provided inside the mixing tank 1, and the stirring assembly is connected to the power pump assembly through a pipe. The stirring assembly is also connected to the self-priming disinfection machine.

[0028] Please see Figure 1 and Figure 2 The self-priming disinfection mechanism includes a self-priming pipe 2 connected in series on the output pipe of the power pump assembly. The self-priming pipe 2 is connected to the stirring assembly. A spray pipe 3 is fixedly connected to the inner wall of the self-priming pipe 2. The inner diameter of the inlet end of the spray pipe 3 is larger than the inner diameter of the outlet end. The inlet end of the spray pipe 3 is fixedly connected to the inner wall of the self-priming pipe 2. The outlet end of the spray pipe 3 is located in the middle of the cavity of the self-priming pipe 2. A suction branch pipe 4 is fixedly connected to the upper part of the self-priming pipe 2. The suction branch pipe 4 is connected to the self-priming pipe 2, and the outlet end of the suction branch pipe 4 is located close to the outlet end of the spray pipe 3. The suction branch pipe 4 is connected to a silicone tube 5 for communicating with the disinfectant tank.

[0029] In practical applications, driven by the power pump assembly, the liquid flows rapidly within the cavity of the self-priming pipe 2. After passing through the nozzle 3 within the cavity, the liquid flows in a jet-like manner because the inner diameter of the inlet end of the nozzle 3 is larger than the inner diameter of the outlet end. This results in a negative pressure state between the outlet end of the nozzle 3 and the edge area of ​​the inner cavity of the self-priming pipe 2. Under atmospheric pressure, the disinfectant in the disinfectant tank is automatically drawn into the self-priming pipe 2 through the suction branch pipe 4 located at the outlet end of the nozzle 3 and the silicone tube 5 connected to the suction branch pipe 4. The disinfectant then enters the mixing tank 1 through the pipe connected to the self-priming pipe 2 and the stirring assembly. Driven by the power pump assembly, the liquid in the mixing tank 1 is stirred and mixed to achieve self-priming disinfection. This invention automatically draws the disinfectant into the mixing tank 1 through the negative pressure generated by the liquid flow, effectively preventing the disinfectant from splashing and evaporating during its entry into the mixing tank 1, thereby protecting human safety and avoiding harm to human health.

[0030] Please see Figure 1 An electric ball valve 6 for controlling the start and stop of disinfectant inhalation is connected between the inhalation branch tube 4 and the silicone tube 5.

[0031] By controlling the opening or closing of the electric ball valve 6, the start and stop of disinfectant intake can be controlled, allowing the disinfectant to enter the mixing tank 1 in a controllable manner.

[0032] Please see Figure 1 , Figure 3 and Figure 4 The stirring assembly includes a shaft tube 7 that communicates with the power pump assembly. The shaft tube 7 is disposed inside the liquid mixing tank 1 and located at the lower part of the liquid mixing tank 1. Multiple windows 8 are opened on the side of the shaft tube 7. An inwardly curved nozzle is rotatably connected to the shaft tube 7. The nozzle communicates with the shaft tube 7 through the window 8.

[0033] Driven by the power pump assembly, the liquid in the upper part of the liquid mixing tank 1 quickly enters the shaft tube 7, and then enters the lower part of the liquid mixing tank 1 through the window 8 and the nozzle in sequence, mixing the liquid in the upper part of the liquid mixing tank 1 with the liquid in the lower part of the liquid mixing tank 1 to achieve stirring; at the same time, since the nozzle is bent inward, it is pushed to rotate under the reaction force of the sprayed liquid, further achieving uniform stirring.

[0034] Please see Figures 3 to 5 The nozzle includes a sleeve 9 rotatably connected to the shaft tube 7, a side tube 10 fixedly connected to the sleeve 9, the side tube 10 communicating with the sleeve 9, the side tube 10 communicating with the shaft tube 7 through the window 8, an inwardly bent connecting tube connected to the side tube 10, and a nozzle 11 connected to the connecting tube.

[0035] Driven by the power pump assembly, the liquid in the upper part of the liquid mixing tank 1 quickly enters the shaft tube 7 and enters the sleeve 9, side tube 10, connecting tube and nozzle 11 in sequence through the window 8 of the shaft tube 7. Since the connecting tube is bent inward, under the reaction force of the liquid jet, the sleeve 9 is pushed to drive the side tube 10, connecting tube and nozzle 11 to rotate relative to the shaft tube 7.

[0036] Please see Figures 3 to 5 Multiple side tubes 10 are fixedly connected to the sleeve 9, and two side tubes 10 are symmetrically arranged to connect the connecting tube in the same symmetrical direction of inward bending.

[0037] Liquid is sprayed through the connecting pipe and nozzle 11 connected by multiple side pipes 10, which pushes the sleeve 9 to rotate from different directions, accelerates the rotation of the nozzle, and mixes with the liquid in the lower part of the liquid mixing tank 1 from multiple directions, further improving the stirring efficiency.

[0038] Please see Figure 3 and Figure 4 The connecting pipe includes a straight pipe 12 connected to the side pipe 10, the straight pipe 12 is connected to an inclined pipe 13, the inclined pipe 13 is connected to an inwardly hooked end pipe 14, and the end pipe 14 is connected to the nozzle 11.

[0039] The liquid enters the nozzle 11 through the inclined tube 13 connected to the straight tube 12 and the inwardly hooked end tube 14 connected to the inclined tube 13, and is then sprayed out, causing the liquid to spray out tangentially and obliquely around the circumference of the sleeve 9, thereby driving the nozzle to rotate. The buffering effect of the liquid in the liquid mixing tank 1 also prevents the generation of noise.

[0040] Please see Figure 3 and Figure 4 The nozzle 11 is duckbill shaped.

[0041] The duckbill-shaped nozzle 11 narrows the liquid outlet, effectively enhancing the jetting power of the nozzle on the basis of existing power, which reduces the output power burden of the power pump assembly to achieve stirring.

[0042] Please see Figure 5 A limiting ring 15 is fixedly sleeved on the shaft tube 7. The limiting ring 15 is located below the sleeve 9. A plug 16 for limiting the sleeve 9 is located above the sleeve 9. The plug 16 is connected to the shaft tube 7.

[0043] The plug 16 seals the upper end of the shaft tube 7, and the outer diameter of the plug 16 is larger than the outer diameter of the shaft tube 7. Under the limiting action of the limiting ring 15 and the plug 16, the sleeve 9 rotates between the limiting ring 15 and the plug 16 with the shaft tube 7 as the axis.

[0044] Please see Figure 1The power pump assembly is located on the outer wall of the liquid preparation tank 1.

[0045] The power pump assembly is hung on the wall of the liquid mixing tank 1. After the liquid is drained, the liquid is completely discharged from the power pump assembly due to gravity, effectively avoiding liquid residue in the power pump assembly after the liquid is drained.

[0046] Please see Figure 1 The power pump assembly includes multiple micro water pumps 17 connected in parallel. All of the multiple micro water pumps 17 in the stirring assembly are connected together. The self-priming pipe 2 is connected to any one of the micro water pumps 17.

[0047] By connecting multiple micro water pumps 17 in parallel, the stirring components are powered simultaneously. Each micro water pump 17 shares the power required for stirring, replacing the need for a single high-power power source and avoiding noise generation.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
