Spraying rotating stirring device for preparing dialysate

Abstract

The invention discloses a spraying rotating stirring device for preparing dialysate. Reverse osmosis water enters a spraying rotating stirring spray head through a circulating pipeline I, a micro circulating water pump and a circulating pipeline II, a part of solution in an inner cavity communicated with the spray head is sprayed out to form a water column through a reverse pushing type spraying rotating hole, the generated counter-acting force pushes the spraying rotating stirring spray head to continuously rotate to act on the dialysis powder at the bottom of a container, the dialysis powder is in a suspended state, spraying rotating stirring on the dialysis powder and reverse osmosis water are realized, spraying and rotating stirring spray head rotates for brushing, no dead angle is left, and not only is the dialysate fully and completely mixed uniformly, but also vortexes, bubbles, water spots and the like cannot be generated in the mixing and stirring process,so that the quality of the dialysate is improved. By using the spraying rotating stirring spray head, the preparation of the dialysis concentrated solution can be completed by using a micro pump with lower power, the noise is low, and the spray head is suitable for completing the preparation of the dialysis concentrated solution more efficiently and with high quality in a quiet medical environment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a jet rotary stirring device used for preparing dialysis solution, which is aimed at being used in the process of preparing hemodialysis concentrate. Background technique [0002] In a hospital dialysis center or an independent dialysis center, before performing hemodialysis treatment on uremia patients, two concentrated dialysates need to be prepared: liquid A and liquid B (hereinafter referred to as: dialysate). The main component of liquid B is a certain concentration of sodium bicarbonate (NaHCO 3 ) solution, in the preparation process, it is required to minimize the therapeutic active ingredient "bicarbonate ion" ( - HCO 3 ) loss (NaHCO 3 +H 2 O→Na 2 CO 3 +CO 2 ↑). The specific methods are as follows: ①The preparation and stirring time should not be too long; ②When stirring, there should be no splash or vortex formation. The current operation pro...

AI Technical Summary

Problems solved by technology

But when preparing dialysate, using the above two methods to stir, there are following deficiencies or defects: 1. The motor drives the blades to rotate and stir, which is prone to splashes or vortexes, and the B liquid effect component ( — HCO 3 ) is easy to lose; 2. When using a water pump, the impeller in the pump will contact and rub against the solid solute for a long time under high-speed operation, and the damage rate is high. At least 1 to 2 water pumps must be replaced every year; 3. The dissolution efficiency is relatively low: for To ensure that the dialysis powder (solute) can suspend and flow in the solution without leaving a dead angle, it is necessary to install the blade driven by the motor near the bottom of the container, or the water flow injected by the water pump must be inclined downward; the above two structures can be Most of the solid solutes are suspended in a solution with a relatively high concentration for dissolution, so it takes a long time for the stirring process; 4. The above two solutions require the use of a motor or a pump with a large power, that is, the noise during operation is large , not compatible with the quiet medical environment
