A hemodialysis device is a device that purifies the blood by bringing blood and dialysate into contact with each other via a membrane and transferring waste products in the blood into the dialysate. There are two types of dialysate: one containing sodium bicarbonate and the other containing sodium acetate.
Recently, the former is mainly used. By the way, since the drug that is the raw material for the dialysate is generally sold in powder form, it is necessary to dissolve it in water and adjust it to a predetermined concentration before use. Therefore, a method generally adopted is to first prepare a stock solution of a predetermined concentration by dissolving the powder in water in a dialysate stock solution preparation device, and then supply this to a dialysate supply device and dilute it to obtain the final dialysate. ing. Conventionally used dialysate stock solution preparation devices have stirring blades attached to the top of the tank and are forcibly stirred by a motor, and the shape of the stirring blades is also commonly used in other fields. In addition, in Japanese Patent Application Laid-open No. 62-269735, there is a method in which a blade made of a hollow pipe with many holes is fixed to a rotor.
An apparatus has been proposed in which a liquid is circulated and ejected from the holes, and the reaction force is used to rotate a rotor to perform stirring.

When preparing a sodium bicarbonate-based dialysate,
In conventional dialysate stock solution preparation devices, if the stirring is slow, the drug will not be completely dissolved and will settle at the bottom of the tank, so it must be stirred at a considerable speed. There was a problem that the decomposition of sodium carbonate was accelerated. That is, a reaction occurs in which sodium bicarbonate decomposes into sodium carbonate and carbon dioxide gas due to the impact caused by stirring and the entrainment of air bubbles into the liquid, which is not preferable. In addition, with conventional equipment, powder settles in the dialysate stock supply line connected to the bottom of the tank.
A phenomenon in which the dialysate is supplied as is to the dialysate supply device without being dissolved also occurs, and a solution to this problem has been desired.

末を完全に溶解することは困難であつた。 Furthermore, according to experiments conducted by the applicant using a device similar to the device disclosed in JP-A-62-269735, the decomposition of sodium bicarbonate is not accelerated because the stirring is performed slowly. but,
The powder gradually settled at the bottom of the tank and it was difficult to completely dissolve all the powder.

Another object of the present invention is to provide a dialysate stock solution preparation device that prevents the precipitation of powder in a fluid delivery line.

In the present invention, the above first objective was achieved by devising the structure of the stirring blade installed in the tank. That is, the stirring blades used in the present invention have a hollow central shaft installed vertically at the bottom of the tank, and a plurality of horizontally rotating blades with one end attached almost perpendicular to the central axis and symmetrically with respect to the central axis. The hollow blades have their outer ends closed and their inner ends communicating with the inside of the central shaft, and on either side of these hollow blades, near the outer ends There are holes that face diagonally downward and holes that face horizontally, and holes that face downward near the center and near the inner end, respectively, and the sum of each type of hole is located symmetrically with respect to the central axis. The holes are drilled to satisfy the condition that the number is 2 or more, and the liquid introduced from the bottom of the central shaft is ejected from the hole provided in the hollow blade, thereby stirring the liquid while rotating the hollow blade. It is structured to perform the following.

る。 In addition, the dialysate stock solution preparation device in which this stirring blade is installed consists of a tank, a stirring blade with the above structure installed at the bottom of the tank, and a circulation line that extracts the liquid from the tank and supplies it to the inside of the central shaft of the stirring blade. and a pump installed in the circulation line, and in order to achieve the second objective mentioned above,
The liquid supply line to the dialysate supply device is branched in the middle of the circulation line, and a three-way valve is provided at the branch.

In the dialysate stock solution preparation device of the present invention, the liquid ejected from holes provided at specific positions in the hollow blades of the stirring blades prevents powdered drugs floating near the bottom of the tank or attempting to settle over the entire area. It is blown up and stirred. In addition, since the hollow blades are rotated by the force in the opposite direction due to the jet flow, the entire tank is also agitated, and the collision between the blades and the powder destroys the powder and promotes dissolution. A uniform solution can be efficiently prepared. The stirring blades rotate slowly and do not apply large local forces to the liquid or entrain air bubbles, so the decomposition of sodium bicarbonate is almost the same as when the liquid is left standing.

で自由に変えることができる。 FIG. 2 is a perspective view showing details of the stirring blade.
As can be seen from the figure, the stirring blade 2 has a hollow central shaft 11 and four rod-shaped hollow blades 12, 13, 14, 1.
5, and one end of the hollow blade is attached perpendicularly and symmetrically to the central axis. The central shaft and the inside of the hollow blade are in communication, and the outlet 6 of the circulation line is connected to the lower part of the central shaft. The other end of the hollow wing is closed, and numerous holes are provided on the side surface. In this invention, the position and direction of these holes are important, and holes facing diagonally downward and horizontally are provided near the outer end of the hollow wing, and holes near the center and inside are provided. A hole facing downward is provided near each end. It is not necessary to provide all of these four types of holes in each hollow blade, but the total number of holes of each type is 2 or more in any hollow blade at symmetrical positions with respect to the central axis. It is necessary to provide the following conditions. That is, at least one set of each type of holes must be provided at symmetrical positions of a plurality of symmetrically arranged hollow blades. In the example shown in Figure 2,
Holes 16, 17 and 23, 24 are drilled diagonally downward in the side surfaces near the outer ends of the symmetrically arranged hollow wings 12 and 14, and holes 16, 17 and 23, 24 are drilled diagonally downward in the other symmetrically arranged hollow wings 13 and 15. Also, the hole 19 is directed diagonally downward.
and 26. The angle at which the holes are provided is suitably 10 to 50 degrees with respect to the horizontal plane, and particularly preferably 20 to 40 degrees. These holes provide rotational force to the blades and at the same time stir the powder around the bottom of the tank to prevent settling. The number of holes must be at least two in total, but should be selected appropriately depending on the number of hollow wings, the size of the tank, etc. Further, the holes 18, 20, 25, and 27 are provided in the horizontal direction, and have the function of rotating the blades and stirring the powder floating around the blades, and the holes 20 and 27 near the outer end are Although two or more are essential, it is preferable to provide them also at positions 18 and 25 near the inner end. Note that these holes and the holes described above are naturally provided so as to apply rotational force in the same direction of the blade. Next, holes 21, 22, 28, 2
9 is drilled downward and stirs the powder that is about to settle at the bottom of the tank,
Two or more are required. Note that these holes should be provided symmetrically with respect to the central axis in order to ensure smooth rotation of the blade. Furthermore, although the above example shows one with four hollow blades, the number may be other than four as long as it is symmetrical about the central axis, and the number and position of the holes also meet the above conditions. You can change it freely within the range you want.

Furthermore, as shown in FIG. 1, there is no place in the circulation line where the liquid stagnates, so even if powder enters the circulation line, it will not settle in the middle of the line. When the preparation of the dialysate stock solution is completed, switch the three-way valve so that the inlet side of the circulation line and the liquid supply line are in communication and the outlet side is closed, and supply the dialysate to the dialysate supply device using the liquid supply pump (not shown). Transfer the dialysate stock solution.

By using the dialysate stock solution preparation device of the present invention, it is possible to efficiently and completely dissolve the powdered drug that is the raw material for the dialysate. Moreover, since the stirring is performed slowly, the decomposition of sodium bicarbonate is not accelerated. In addition, a three-way valve was installed at the branch of the circulation line from the liquid supply line to eliminate a place where the liquid would accumulate, so the dialysate stock solution containing undissolved powder will not be transferred to the dialysate supply device. .
