Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a jet rotary stirring device for preparing dialysate, which is used in the process of preparing hemodialysis concentrated solution.
Background
In a hospital dialysis center or an independent dialysis center, two concentrated dialyzates need to be prepared before hemodialysis treatment is carried out on uremia patients: solution A and solution B (hereinafter referred to as dialysate). Wherein the main component of solution B is sodium bicarbonate (NaHCO) with certain concentration3) Solutions, in the preparation of which it is desired to minimize the therapeutically active ingredient "bicarbonate ion" (ii) in-HCO3) Loss of (NaHCO)3+H2O→Na2CO3+CO2×) in the table. The specific method comprises the following steps: firstly, the preparation and stirring time is not suitable for too long; ② water splash or vortex should not be formed during stirring. The current operation flow (the preparation methods of two concentrated solutions are the same, and the preparation dosage is constant): putting the dialysis powder (solute) into a preparation container → injecting quantitative reverse osmosis water (solvent) → stirring → filtering after complete dissolution → split charging → ready to use or standby. The difference lies in the stirring method during preparation: 1. a motor is used for driving a connecting rod-blade extending into the container to rotate for stirring; 2. the dialysis powder (solute) and the reverse osmosis water (solution) which are sunk at the bottom of the container are sucked into the pump by a water pump and then pumped into the container through a communicating pipeline, and the dialysis powder (solute) and the reverse osmosis water (solution) are circularly reciprocated and stirred.
When the solute and the solvent are dissolved in a static state, the method is characterized in that: firstly, a solid solute with higher specific gravity sinks at the bottom of a container; the bottom of the container to the surface of the solvent are respectively as follows: solute → saturated solution → solution of higher concentration → solution of lower concentration → solvent. ③ under the same temperature condition, the dissolution speed depends on the solid soluteThe lower the surrounding solution concentration, i.e., the lower the solution concentration, the faster the solute dissolves. When external force is used for stirring and dissolving, the solute is in a suspension flowing state, the effect is to continuously change (reduce) the concentration of the solution around the solid solute, and the dissolving process is accelerated. However, when preparing the dialysate, the above two methods are used for stirring, and the following disadvantages or shortcomings exist: 1. the motor drives the blades to rotate and stir, water splash or vortex is easy to appear, and B liquid effective component (A)—HCO3) Is easy to lose; 2. the method is characterized in that a water pump is used, an impeller in the pump is in contact with and rubs against a solid solute for a long time under high-speed operation, the damage rate is high, and at least 1-2 water pumps are replaced every year; 3. the dissolution efficiency is relatively low: in order to ensure that dialysis powder (solute) can flow in a suspension manner in a solution without dead corners, blades driven by a motor are required to be arranged at a position close to the bottom of a container, or water flow sprayed by a water pump is required to be inclined downwards; the two structures can enable most of solid solute to be suspended in solution with relatively high concentration for dissolution, so a long-time stirring process is needed; 4. the two schemes require a motor or a water pump with larger power, namely, the noise is large during operation, and the two schemes are not suitable for a quiet medical environment.
