Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, and in particular to an automatic production device for hemodialysis concentrate. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The entire process is called hemodialysis. Hemodialysis concentrate is composed of A concentrate and B concentrate. A concentrate is composed of an aqueous solution of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, and glacial acetic acid, and B concentrate is composed of an aqueous solution of sodium bicarbonate or sodium bicarbonate and sodium chloride.

In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-7 The present invention discloses an automatic production device for hemodialysis concentrate, comprising:

[0046] The tank body 1 is used to carry the concentrated liquid. It is easy to imagine that the tank body 1 is provided with a water inlet pipe and a discharge pipe for inputting the aqueous solution and discharging the mixed concentrated liquid;

[0047] A cover 2, wherein the cover 2 is disposed on the tank body 1 to seal the tank body 1;

[0048] A feeding part 3, the feeding part 3 is arranged on the cover body 2, the feeding part 3 is used to carry materials, and a loss-in-weight scale 32 is arranged between the feeding part 3 and the cover body 2;

[0049] A power unit 4, wherein a first transmission wheel 41 and a second transmission wheel 42 are coaxially arranged at an output end of the power unit 4;

[0050] The transmission part 5 is arranged in the tank body 1, and includes a guide tube 51 with a hollow interior. A first driven wheel 52 meshing with the second transmission wheel 42 is arranged at one end of the guide tube 51, and a third transmission wheel 53 is arranged at the other end of the guide tube 51;

[0051] A first circulation part 6, which is arranged at the center of the bottom wall of the tank body 1 and corresponds to the guide pipe 51, and includes a second driven wheel 61 and a first blade 62 which are transmission-connected to the first transmission wheel 41, and is used to agitate the concentrated liquid to flow along the transmission part 5 under the drive of the power part 4;

[0052] The second circulation part 7 is arranged on the side wall of the tank body 1, and the second circulation part 7 includes a transmission rod 71 rotatably arranged on the tank body 1, one end of the transmission rod 71 is provided with a third driven wheel 72 which is transmission-connected to the third transmission wheel 53, and the other end of the transmission rod 71 is provided with a second blade 73 for agitating the concentrated liquid to flow along the side wall of the tank body 1 under the drive of the power unit 4.

[0053] When the present application is used, the powder material is regularly filled into the feeding part 3, and then after the specified aqueous solution is filled, the corresponding amount of powder material is discharged into the tank body 1 through the weight loss scale 32 arranged thereon, and then the power part 4 is started. When the power part 4 is running, the first transmission wheel 41 and the second transmission wheel 42 arranged thereon respectively drive the first circulation part 6 and the second circulation part 7 to run;

[0054] During the operation of the first circulation section 6, the second driven wheel 61 is meshed with the first transmission wheel 41, driving the first blade 62 to rotate, thereby drawing the aqueous solution located in the center of the bottom of the tank body 1 from bottom to top into the guide tube 51 and being discharged from its upper part. During the operation of the second circulation section 7, it is meshed with the first driven wheel 52. When the transmission section 5 rotates as a whole, the third transmission wheel 53 arranged thereon can drive multiple transmission rods 71 ​​to operate, thereby driving the aqueous solution located on the side of the tank body 1 to circulate, thereby improving the mixing efficiency.

[0055] In a preferred embodiment, the first blade 62 and the second blade 73 are in opposite directions to encourage the concentrated liquid to circulate inside the tank body 1. In this embodiment, during the mixing process, the concentrated liquid can suck the aqueous solution located in the center of the bottom of the tank body 1 and discharge it from the top, and then flow from its side to the bottom of the tank body 1 for circulating mixing, thereby avoiding the situation where the powder material is deposited at the bottom of the tank body 1 during the mixing process.

[0056] In another embodiment, the first blade 62 and the second blade 73 have the same direction. In this embodiment, the concentrated liquid in the middle and the concentrated liquid on the side can be driven to blend with each other, thereby improving the mixing effect.

[0057] It should be noted that a transfer bin 21 is provided on the cover body 2, and a material storage tank 22 is provided at the bottom of the transfer bin 21;

[0058] The storage tank 22 is used to carry powder materials, and a filter hole is opened on the storage tank 22;

[0059] The filter hole diameter is smaller than the particle size of the powder material.

[0060] Furthermore, an extension pipe 24 is provided in the transfer bin 21, and the extension pipe 24 is threadedly connected to the storage tank 22. The threaded connection is to facilitate the cleaning of impurities and agglomerated materials deposited inside the storage tank 22 after it is disassembled;

[0061] The transfer bin 21 is provided with an extension mechanism 23 for driving the extension tube 24 to extend and retract, so as to drive the storage tank 22 to extend into the guide tube 51 .

[0062] Through the above-mentioned structural arrangement, the material is held in the storage tank 22 and then extends into the guide pipe 51, so that during the operation of the first circulation section 6, the aqueous solution inside the tank body 1 can quickly flush the material inside the storage tank 22 for mixing, and can also be used to separate the agglomeration of powder materials and the impurities therein.

[0063] It should be noted that a liquid level sensor is provided on the inner wall of the tank body 1 to detect the height of the liquid level inside the tank body 1 .

[0064] Specifically, the loss-in-weight scale 32 is disposed between the cover 2 and the feeding portion 3;

[0065] The feeding part 3 also includes a storage bin 31, and a discharge pipe extending to the interior of the transfer bin 21 is provided at the bottom of the storage bin 31. A control valve is provided on the discharge pipe. The control valve and the loss-in-weight scale 32 are used to quantitatively feed powder material into the storage tank 22 according to the liquid level height inside the tank body 1.

[0066] Through the above structural setting, the device can achieve the effect of automatic proportioning. It is easy to think that the device should also include related equipment such as a controller and a control panel. Since this part of the equipment belongs to the prior art, it is not described in detail;

[0067] When it is necessary to produce concentrates of different proportions, the required amount of the corresponding aqueous solution can be calculated by preset information, and then the required content of the powder material can be calculated according to the required concentration, and then the corresponding content is discharged into the tank 1 through the loss-in-weight scale 32 for mixing.

[0068] It should be noted that the second circulation parts 7 are in multiple groups and are evenly distributed on the inner wall of the tank body 1 .

[0069] It is easy to imagine that a receiving ring 11 is provided on the inner wall of the tank body 1;

[0070] The receiving ring 11 is used to carry the third transmission wheel 53 , and the third transmission wheel 53 is meshed with each of the third driven wheels 72 .

[0071] like Figure 1 As shown, a gap is provided between the first driven wheel 52 and the bottom wall of the tank body 1 , and the first circulation portion 6 is provided at the gap between the first driven wheel 52 and the tank body 1 .

[0072] The diameter of the first transmission wheel 41 is greater than the diameter of the second transmission wheel 42;

[0073] Finally, it should be added that a stirring element (not shown in the figure) is provided on the outer surface of the guide tube 51. The form and arrangement of the stirring element can be arranged in a manner that can be easily thought of by technicians in this field, so as to stir the aqueous solution synchronously during the circulation process inside the tank body 1, thereby further improving the mixing efficiency.

[0074] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0075] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0076] In addition, "plurality" means two or more.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
