Description

Technical Field

[0001] This application relates to the field of blood purification technology, and more particularly to a preparation device containing glucose dialysis concentrate. Background Technology

[0002] In hemodialysis treatment, hemodialysis concentrate is a key component in the preparation of dialysate, typically containing sodium chloride, potassium chloride, calcium chloride, magnesium chloride, and organic acids. For patients with diabetic nephropathy, traditional glucose-free dialysate can easily cause complications such as hypotension and hypoglycemia during hemodialysis, adversely affecting the safety and tolerability of treatment. In recent years, glucose-concentrated dialysate has become increasingly widely used because it effectively reduces fluctuations in blood pressure and blood glucose levels in hemodialysis for diabetic nephropathy and does not cause excessive activation of the sympathetic nervous system, thus improving patient prognosis.

[0003] In the production of glucose-containing hemodialysis concentrate, anhydrous glucose is typically used as the raw material for the sugar component. However, anhydrous glucose powder exhibits significant clumping and floating during dissolution, resulting in a slow dissolution rate. This problem is particularly pronounced in large-scale production using mixing tanks with a capacity of 30 tons or more. In large-scale production, it is difficult to implement vigorous stirring to promote glucose dissolution, easily leading to incomplete glucose dissolution and consequently, unstable glucose concentration in the concentrate, affecting product quality.

[0004] Anhydrous glucose is highly hygroscopic. The clumping mechanism during its dissolution process is mainly as follows: When anhydrous glucose powder is poured into water, the surface of the particles in contact with the water rapidly absorbs moisture and dissolves instantly, forming a high-concentration glucose solution. This high-concentration solution has a very high viscosity, acting like a "gum jelly" or "syrup" to coat the undissolved dry powder particles. This high-viscosity syrup-like liquid forms "liquid bridges" between adjacent particles. The strong surface tension generated by these liquid bridges tightly binds the surrounding glucose particles together, causing the outer particles to first agglomerate and form a dense "protective shell." This "protective shell" significantly hinders the internal dry powder particles from fully contacting the water. Simultaneously, within the agglomerated clumps, air is trapped between the dry particles, forming "air traps," further hindering moisture penetration into the clumps, resulting in a very slow overall dissolution process for the glucose. The complete process can be summarized as: exposure and moisture absorption → instantaneous surface dissolution → formation of a high-viscosity syrup layer → formation of liquid bridges between particles → clumping → formation of a protective shell on the outside of the clumps and an air trap inside → hindering internal dissolution.

[0005] Therefore, the key to accelerating glucose dissolution lies in achieving sufficient dispersion of glucose particles to avoid clumping. Currently, the common industrial solution is to slowly add glucose powder while stirring, but this method severely restricts production efficiency in large-scale production and cannot meet the needs of industrial-scale production. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a preparation device for glucose dialysis concentrate, which can shorten the glucose dissolution time and meet the needs of large-scale industrial production.

[0007] To achieve the above technical objectives, this application provides a preparation device for glucose dialysis concentrate, including a preparation tank, a sprayer, and a feeding screen;

[0008] The feeding screen is positioned above the mixing tank and extends into the interior of the mixing tank;

[0009] The portion of the feeding sieve that extends into the preparation tank is provided with sieve holes;

[0010] The sprayer is installed in the preparation tank, and the spraying end extends into the preparation tank and is positioned towards the feeding screen.

[0011] Furthermore, the end of the feeding sieve that extends into the preparation tank is funnel-shaped.

[0012] Furthermore, it also includes a vibration mechanism;

[0013] The vibration mechanism is installed outside the preparation tank and connected to the feeding screen to drive the feeding screen to vibrate.

[0014] Furthermore, it also includes a delivery pump and an outlet pipe;

[0015] One end of the outlet pipe is connected to the outlet of the preparation tank, and the other end is connected to the inlet of the delivery pump.

[0016] Furthermore, it also includes circulation pipes;

[0017] One end of the circulation pipe is connected to the output port of the delivery pump, and the other end is connected to the sprayer.

[0018] Furthermore, it also includes a feeding pipe;

[0019] The feeding pipe is connected to the feeding screen and is used to feed glucose powder to the feeding screen.

[0020] Furthermore, it also includes a stirring device;

[0021] The stirring device includes a stirring motor and a stirring blade assembly;

[0022] The stirring blade assembly is rotatably mounted in the preparation tank, with one end extending out of the preparation tank;

[0023] The output shaft of the stirring motor is connected to one end of the stirring blade assembly, and is used to drive the stirring blade assembly to rotate.

[0024] Furthermore, it also includes a storage tank and a first connecting pipe;

[0025] One end of the first connecting pipe is connected to the output port of the delivery pump, and the other end is connected to the inlet of the storage tank.

[0026] Furthermore, it also includes a filling unit and a second connecting pipe;

[0027] The outlet of the storage tank is connected to the inlet of the filling unit via the second connecting pipe;

[0028] It also includes a third connecting pipe;

[0029] The filling unit is connected to the inlet of the storage tank via the third connecting pipe.

[0030] Furthermore, a filter assembly is connected in series on the first connecting pipe and / or the second connecting pipe;

[0031] A check valve is installed on the second connecting pipe.

[0032] As can be seen from the above technical solutions, the equipment for preparing glucose dialysis concentrate designed in this application has the following beneficial effects:

[0033] 1. The feeding sieve disperses glucose powder into fine particles through the sieve holes, reducing the initial size of particle agglomeration, increasing the contact area between particles and water, and weakening the basis for particle adhesion.

[0034] 2. The sprayer is directed towards the feeding screen to wash away glucose particles adhering to the screen surface in a timely manner, preventing them from clumping and clogging the screen. On the other hand, the liquid washing can further disperse the small particles falling through the screen holes, breaking the binding effect of the syrup layer formed in the initial dissolution of glucose particles, and preventing small particles from agglomerating to form a dense "protective shell". This effectively hinders the key step in the agglomeration mechanism of "liquid bridges between particles → agglomeration", and significantly accelerates the dissolution rate of glucose.

[0035] 3. Compared with the traditional method of slowly adding while stirring, this equipment achieves rapid and dispersed feeding of glucose powder through the combination of feeding screen dispersion and spray rinsing, which improves production efficiency and meets the needs of large-scale production such as preparation tanks with a capacity of 30 tons or more; the glucose dissolves more fully and evenly, effectively solving the problem of unstable concentration caused by insufficient glucose dissolution in large-scale production, and improving the product quality of glucose-containing dialysis concentrate.

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0042] This application discloses an apparatus for preparing glucose dialysis concentrate.

[0043] Please see Figure 1 One embodiment of a preparation device for glucose dialysis concentrate provided in this application includes:

[0044] Preparation tank 1, sprayer 3, and feeding screen 2;

[0045] The feeding screen 2 is set above the preparation tank 1 and extends into the preparation tank 1 through the opening provided on the preparation tank 1; the part of the feeding screen 2 that extends into the preparation tank 1 is provided with screen holes 21; the sprayer 3 is installed on the preparation tank 1, and the spraying end extends into the preparation tank 1 and is set towards the feeding screen 2.

[0046] The equipment for preparing glucose dialysis concentrate designed in this application has the following beneficial effects:

[0047] 1. The feeding sieve 2 disperses glucose powder into fine particles through the sieve holes 21, reducing the initial size of particle agglomeration, increasing the contact area between particles and water, and weakening the basis for particle adhesion.

[0048] 2. The sprayer 3 is set to spray towards the feeding screen 2. On the one hand, it prevents glucose powder from clogging the screen holes 21 and ensures smooth feeding. On the other hand, the spraying water flow fully contacts the fine particles passing through the screen holes 21, so that the particle surface is evenly wetted, avoiding the instantaneous formation of an excessively thick layer of high-viscosity glucose solution on the particle surface (a key initial step in the agglomeration mechanism), thereby reducing the possibility of particles agglomerating due to liquid bridging. After being sprayed and moistened, the dispersed fine particles enter the preparation tank 1 without forming a dense "protective shell" and an internal "air trap" (the core obstacle structure to agglomeration), allowing water to fully penetrate into the particle interior and significantly accelerating the glucose dissolution rate.

[0049] 3. Compared with the traditional method of slowly adding while stirring, this equipment achieves rapid and dispersed feeding of glucose powder through the combination of dispersion by feeding screen 2 and spraying, which improves production efficiency and meets the needs of large-scale production such as preparation tank 1 with a capacity of more than 30 tons; the glucose dissolves more fully and evenly, effectively solving the problem of unstable concentration caused by insufficient glucose dissolution in large-scale production, and improving the product quality of glucose-containing dialysis concentrate.

[0050] The above is Embodiment 1 of a preparation device for glucose dialysis concentrate provided in this application. The following is Embodiment 2 of the same device. Please refer to the following for details. Figure 1 .

[0051] Based on the solution of Embodiment 1 above:

[0052] Furthermore, the feeding screen 2 extends into the preparation tank 1 in a funnel shape at one end.

[0053] This funnel-shaped design allows glucose powder to pass through the sieve holes 21 more concentratedly during its descent, preventing accumulation and uneven dispersion within the feeding sieve 2. Furthermore, the funnel-shaped structure enhances the rinsing effect of the sprayer 3. When the water flow from the sprayer 3 hits the funnel-shaped feeding sieve 2, the water flow forms a more concentrated rinsing area along the funnel wall, more effectively flushing the glucose powder through the sieve holes 21 and further preventing clogging. Simultaneously, this concentrated rinsing method allows the water flow to fully contact the glucose powder, ensuring more uniform wetting of the glucose powder particles and further improving the glucose dissolution rate.

[0054] Furthermore, the aperture of sieve 21 is no larger than 20 mm. Limiting the aperture of sieve 21 to no more than 20 mm ensures that the glucose powder is effectively dispersed into particles of a suitable size when passing through the sieve. If the aperture of sieve 21 is too large, the glucose powder cannot be sufficiently dispersed, and larger particles may directly enter the preparation tank 1, increasing the risk of particle agglomeration and hindering the subsequent dissolution process. Controlling the aperture of sieve 21 to no more than 20 mm allows the glucose powder to disperse into fine and uniform particles, enabling better contact with water and thus accelerating dissolution.

[0055] Furthermore, a vibration mechanism (not shown in the figure) is also included. This mechanism is installed outside the preparation tank 1 and connected to the feeding sieve 2, used to drive the feeding sieve 2 to vibrate. The vibration mechanism further assists in the dispersion and feeding of glucose powder. When the vibration mechanism drives the feeding sieve 2 to vibrate, on the one hand, it makes it easier for glucose particles attached to the edges of the sieve holes 21 to fall off, preventing blockage of the sieve holes 21 due to particle accumulation and ensuring the continuity of feeding; on the other hand, vibration allows the glucose powder to be more evenly distributed on the feeding sieve 2, avoiding excessive local accumulation that affects the dispersion effect. In large-scale production, due to the large amount of glucose powder added, this vibration effect can significantly improve the efficiency of glucose powder passing through the sieve holes 21, allowing more glucose powder to be dispersed into fine particles and enter the preparation tank 1 in a timely manner. In addition, the combined use of the vibration mechanism and the sprayer 3 can further improve the dissolution effect of glucose.

[0056] The vibration frequency and amplitude of the vibration mechanism can be adjusted according to actual production conditions. For different production scales and the characteristics of glucose powder, the vibration parameters can be adjusted to achieve the best dispersion effect. For example, when using glucose powder that is highly hygroscopic and prone to clumping, the vibration frequency and amplitude can be appropriately increased to enhance the dispersion effect; while in small-scale production or when the glucose powder has good flowability, the vibration parameters can be reduced to save energy and reduce equipment wear.

[0057] Furthermore, it also includes a transfer pump 4 and a liquid outlet pipe 51; one end of the liquid outlet pipe 51 is connected to the liquid outlet of the preparation tank 1, and the other end is connected to the input port of the transfer pump 4.

[0058] The transfer pump 4 allows the glucose-containing dialysis concentrate prepared in the preparation tank 1 to be smoothly discharged. The outlet pipe 51 connects the preparation tank 1 and the transfer pump 4, forming a liquid transport channel. Under the action of the transfer pump 4, the concentrate can be transported to subsequent processing stages through the outlet pipe 51.

[0059] A first control valve 53 can be installed on the outlet pipe 51. This control valve can precisely regulate the discharge process of the glucose-containing dialysis concentrate. When it is necessary to discharge the concentrate prepared in the preparation tank 1, the first control valve 53 is opened to keep the outlet pipe 51 unobstructed; when it is not necessary to discharge or it is necessary to stop the discharge, the first control valve 53 is closed to block the flow path of the concentrate and effectively prevent the concentrate from flowing out under unexpected circumstances.

[0060] The transfer pump 4 can be a centrifugal pump with a head of not less than 50m and a flow rate of not less than 50m³ / h. These parameters ensure that the transfer pump 4 has sufficient power to transport the prepared glucose-containing dialysis concentrate to the subsequent processing equipment. A head of not less than 50m ensures that the concentrate can overcome certain height differences and pipeline resistance to reach the target location smoothly; a flow rate of not less than 50m³ / h meets the needs of large-scale production and ensures production efficiency.

[0061] Furthermore, it also includes a circulation pipe 52; one end of the circulation pipe 52 is connected to the output port of the delivery pump 4, and the other end is connected to the sprayer 3. The circulation pipe 52 connects the delivery pump 4 and the sprayer 3, forming an internal circulating liquid supply and spraying system. When the delivery pump 4 is working, it draws liquid from the preparation tank 1 and transports it back to the sprayer 3 through the circulation pipe 52. After the glucose powder is repeatedly dispersed, the circulation stops. In this way, the sprayer 3 can continuously obtain liquid for spraying operations without the need for additional external liquid supply equipment, simplifying the structure of the entire preparation equipment. Moreover, the circulating use of liquid in the preparation tank 1 for spraying allows for more complete utilization of the glucose component in the liquid, improving resource utilization. Simultaneously, the circulating spraying further promotes the dissolution of the glucose powder, as the continuously circulating liquid continuously washes over the glucose powder, ensuring more thorough contact with the liquid and accelerating the dissolution process.

[0062] A second control valve (not shown in the figure) can be installed on the circulation pipe 52. This control valve can be used to control the flow of liquid within the circulation pipe 52. When a circulating spray operation is required, the second control valve is opened, allowing the liquid in the preparation tank 1 to be transported to the sprayer 3 through the circulation pipe 52. When the glucose powder has been sufficiently dispersed and dissolved, and no further circulating spray is needed, the second control valve is closed, stopping the liquid circulation. This not only allows for flexible control of the circulating spray process but also avoids unnecessary energy consumption and liquid waste.

[0063] Furthermore, if a large amount of glucose powder needs to be added or the feeding sieve 2 is not large enough, making it impossible to add the glucose powder to the feeding sieve 2 all at once, a feeding pipe (not shown in the figure) can be added. The feeding pipe is connected to the feeding sieve 2 and is used to continuously feed glucose powder to the feeding sieve 2.

[0064] The feeding pipe design makes the addition of glucose powder more flexible and efficient. It can continuously supply glucose powder to the feeding screen 2 according to actual production needs, ensuring the continuity of the production process. Moreover, by controlling the feeding speed of the feeding pipe, the amount of glucose powder entering the preparation tank 1 can be precisely controlled, further improving the stability of product quality.

[0065] The feeding pipe can be connected to a powder storage tank and positioned above the preparation tank 1, achieving gravity-based conveying. An additional vibration mechanism can be added to the powder storage tank to assist in vibration-assisted conveying, allowing the glucose powder to flow more smoothly from the storage tank through the feeding pipe into the feeding sieve 2 under gravity. This combined gravity and vibration conveying method significantly improves the efficiency and reliability of glucose powder conveying, providing strong support for the smooth operation of the entire preparation process. Furthermore, this conveying method has a relatively simple structure, low maintenance costs, and strong practicality and operability in actual production.

[0066] Furthermore, it also includes a stirring device 13; the stirring device 13 includes a stirring motor 11 and a stirring blade assembly 12; the stirring blade assembly 12 is rotatably mounted in the preparation tank 1, and one end extends out of the preparation tank 1; the output shaft of the stirring motor 11 is connected to one end of the stirring blade assembly 12 to drive the stirring blade assembly 12 to rotate.

[0067] The stirring device 13 further promotes the dissolution of glucose powder in the preparation tank 1. When the stirring motor 11 is started, the stirring blade assembly 12 begins to rotate, creating a flow of water agitation within the preparation tank 1. This agitation allows the sprayed and moistened glucose powder particles to be more evenly distributed in the water, preventing local concentrations from being too high or too low.

[0068] On the one hand, the rotation of the stirring blades generates shear force, which further disperses the glucose powder particles. Even after being processed by the feeding screen 2 and sprayer 3, some small particles may still agglomerate. The shear force of the stirring can further break up these agglomerated particles, making them smaller, thereby increasing the contact area with water and accelerating the dissolution process.

[0069] On the other hand, the water circulation created by stirring allows the glucose powder particles to continuously move within the preparation tank 1, ensuring full contact with the water. Water can penetrate the particles more quickly, allowing the glucose to dissolve more completely. Furthermore, stirring prevents glucose powder from settling at the bottom of the preparation tank 1, ensuring the uniformity of the solution throughout the tank.

[0070] The stirring device 13 is an existing stirring design, and those skilled in the art can make appropriate changes and adjustments based on it without limitation.

[0071] Furthermore, it also includes a storage tank 6 and a first connecting pipe 81; one end of the first connecting pipe 81 is connected to the output port of the transfer pump 4, and the other end is connected to the inlet of the storage tank 6. The storage tank 6 is configured to provide a temporary storage space for the prepared glucose-containing dialysis concentrate. Through the first connecting pipe 81, the transfer pump 4 transports the concentrate in the preparation tank 1 to the storage tank 6, thus separating the preparation process from the storage process and facilitating subsequent filling and other operations.

[0072] Furthermore, it also includes a filling unit 7 and a second connecting pipe 82; the outlet of the storage tank 6 is connected to the inlet of the filling unit 7 through the second connecting pipe 82; the filling unit is an existing filling device used to fill the prepared dialysis concentrate into products, and the details will not be elaborated.

[0073] It also includes a third connecting pipe 83, through which the filling unit 7 connects to the inlet of the storage tank 6. The filling unit is connected back to the storage tank 6, facilitating the circulation of the dialysis concentrate and enabling ozone disinfection at the transfer pump 4. Circulation ensures sufficient disinfection time, guaranteeing that the endotoxin content in the product meets standards. Additionally, a check valve 92 is installed on the second connecting pipe 82 to prevent backflow of the dialysis concentrate during transport. When the filling unit 7 is operating normally, drawing concentrate from the storage tank 6 for filling, the check valve 92 allows the liquid to flow smoothly through the second connecting pipe 82 to the filling unit 7. If the filling unit 7 malfunctions or experiences other abnormalities that cause a backflow tendency, the check valve 92 will automatically close, preventing the concentrate from flowing back into the storage tank 6, ensuring the stability and safety of the entire preparation and filling process.

[0074] A third control valve (not shown in the figure), a fourth control valve, and a fifth control valve (not shown in the figure) can be installed on the first connecting pipe 81, the second connecting pipe 82, and the third connecting pipe 83, respectively. These control valves allow for precise control of the liquid flow in different pipelines. The third control valve, installed on the first connecting pipe 81, controls the flow of the prepared glucose-containing dialysis concentrate from the delivery pump 4 to the storage tank 6. When concentrate needs to be delivered to the storage tank 6, the third control valve is opened to allow the liquid to pass through smoothly; when the storage tank 6 reaches its storage limit or no further delivery is needed, the third control valve is closed to stop the liquid flow. The fourth control valve, installed on the second connecting pipe 82, controls the flow of the concentrate from the storage tank 6 to the filling unit 7. At the start of the filling operation, the fourth control valve is opened to allow the concentrate to be drawn into the filling unit 7 for filling; when filling is complete or needs to be paused, the fourth control valve is closed to stop the liquid flow. The fifth control valve, installed on the third connecting pipe 83, mainly controls the liquid circulation process between the filling unit 7 and the storage tank 6. When ozone disinfection or other processes requiring circulation, open the fifth control valve to allow the concentrate to circulate between the filling unit 7 and the storage tank 6; when disinfection is complete or circulation is no longer needed, close the fifth control valve to stop circulation.

[0075] In addition, to facilitate monitoring and management of the entire preparation equipment, an automated control system can be installed. This system can be connected to various control valves, delivery pumps 4, stirring motors 11, and other equipment to achieve remote control and parameter adjustment of the equipment. For example, the automated control system can monitor parameters such as liquid level, temperature, and concentration in the preparation tank 1 in real time, and automatically adjust the speed of the stirring device 13, the flow rate of the delivery pump 4, and the on / off status of various control valves based on these parameters to ensure the stability and accuracy of the entire preparation process.

[0076] Furthermore, a filter assembly 91 is connected in series on the first connecting pipe 81 and / or the second connecting pipe 82. The filter assembly 91 is used to filter undissolved powder particles in the prepared dialysis solution. In addition, ozone or carbon dioxide can be pumped in at the delivery pump 4 for sterilization.

[0077] Taking the example of having filter sets 91 on both the first connecting pipe 81 and the second connecting pipe 82, the pipeline achieves a two-stage filtration design. The filter set 91 on the first connecting pipe 81 serves as the first stage of filtration, and its filter element pore size can be designed to be 0.45μm. The filter set 91 on the second connecting pipe 82 serves as the second stage of filtration, and its filter element pore size can be designed to be 0.22μm, thoroughly filtering undissolved powder and other impurity particles in the dialysate.

[0078] The filter assembly 91 in this application is an existing filter module design. Refer to the filtration design in the preparation method of hemodialysis concentrate B solution published in CN119564600A, or other existing filtration designs applied to hemodialysis concentrate; details will not be elaborated further. The filters in filter assembly 91 can be replaced and cleaned according to actual needs to ensure the stability and continuity of the filtration effect. After a period of use, the filtration efficiency of the filters may decrease, at which point the filters need to be replaced promptly to ensure that the filtered dialysis concentrate meets quality standards.

[0079] The preparation equipment designed in this application is used as follows:

[0080] Add an appropriate amount of deionized water to the mixing tank 1 according to the determined ratio, turn on the delivery pump 4 (open the first control valve 53 and the second control valve, and close the third control valve) to realize the self-circulating spray mode, so that the liquid can be flushed by the sprayer 3 to the feeding screen 2. Add the required glucose powder from the feeding screen 2 while stirring and flushing to disperse the glucose powder. After the glucose powder is completely dispersed, stop the self-circulation and add other ingredients to the feeding screen 2 or other feeding ports, and stir to dissolve for 30 minutes.

[0081] The prepared dialysis concentrate is transported to the filter group 91 of the first connecting pipe 81 for filtration, and then fed into the storage tank 6 for storage. It is then transported to the filling unit for filling according to production needs.

[0082] The above provides a detailed description of the preparation equipment for glucose dialysis concentrate provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
