Dialysis concentrated solution distribution system

Abstract

The invention relates to a dialysis concentrated solution distribution system. The dialysis concentrated solution distribution system comprises a dialysis concentrated solution automatic preparation device (1), a high-temperature disinfection device (2) and a zero-pressure supply device (3), wherein the dialysis concentrated solution automatic preparation device (1) is connected with the high-temperature disinfection device (2) through a pipeline; and the zero-pressure supply device (3) is arranged on the pipeline and is provided with a connector connected with a liquid inlet of a dialysis machine. By adopting the dialysis concentrated solution distribution system disclosed by the invention, automatic preparation work of a dialysis concentrated solution can be realized and the labor intensity of workers is extremely alleviated; the breeding opportunity of microorganisms is reduced through high-temperature heating; stable liquid supply is maintained through the zero-pressure supply device; the dialysis concentrated solution in the system can be immediately used after the solution is prepared at the same day; and the storage time of the dialysis concentrated solution is shortened andthe effectiveness of the dialysis concentrated solution is maintained.

Description

technical field [0001] The invention relates to an auxiliary device in the medical field of nephropathy, which is used in a hospital hemodialysis center, in particular to a dialysis concentrate distribution system. Background technique [0002] The dialysis concentrate distribution system currently in use adopts manual feeding operation, one-time centralized preparation, storage in a large liquid storage tank after filtration, and then transported to the use points of each dialysis machine by a pump and pipeline system, such as Figure 5 shown. This kind of preparation method has great disadvantages. It takes 1-2 hours for the stirring and dissolving process of the open manual feeding, and then it is moved to the liquid storage tank for storage. This activity is usually prepared the day before, otherwise the second Normal dialysis cannot be carried out in one day, resulting in the prepared dialysis concentrate being stored in the storage tank for at least 10 hours before it ...

Problems solved by technology

This kind of preparation method has great disadvantages. It takes 1-2 hours for the stirring and dissolving process of the open manual feeding, and then it is moved to the liquid storage tank for storage. This activity is usually prepared the day before, otherwise the second Normal dialysis cannot be carried out in one day, resulting in the prepared dialysis concentrate being stored in the storage tank for at least 10 hours before it can be used. For the dialysis concentrate prepared by sodium bicarbonate single-component B powder, long-term storage There are two major disadvantages:

[0003] 1. Microorganisms are very easy to breed (YY0598 hemodialysis and related treatment concentrates: the total number of bacteria should not exceed 100 CFU / ml, the total number of fungi should not exceed 10 CFU / ml, and Escherichia coli should not be detected), causing dialysis hazards to patients;

[0004] 2. The bicarbonate ion, the active ingredient in dialysis, is unstable and highly volatile (2NaHCO 3 →Na 2 CO 3 +CO 2 ↑+H 2 O) Reduced effectiveness of dialysis

[0009] For the first method, because the latter stage liquid supply pipeline generally uses a pipe with a diameter of 20mm and a length of 200-300m, this will cause the pressure at the proximal interface to be too high (usually 0.4-0.5MPa), while the pressure at the far-end interface Insufficient or even anhydrous state causes the concentration of the dialysate to fluctuate up and down during the dialysis process, causing the kidney machine to continuously alarm and affect the effective dialysis of the patient; at the same time, due to the high pressure of the proximal interface, the phenomenon of dripping and leaking at the interface occurs from time to time; more What's more, excessive pressure can cause damage to the liquid inlet parts of the kidney machine

[0010] For the second method, the exhaust time of 30 minutes is relatively long and time-consuming, and it cannot fully guarantee the filling of the pipeline liquid (because the installation of the post-stage delivery pipeline should be arranged according to the structure of the room, passing through doors, windows and walls, etc. The position must be raised or lowered, so there is a suffocation point in the liquid supply pipeline), resulting in air entering during the dialysis process, and the equipment alarms, affecting normal dialysis

[0011] In addition, the currently commonly used concentrate distribution system uses chemical disinfection methods, the disinfection process is cumbersome, the effective concentration of the disinfectant (effectiveness of disinfection) and the detection of the residual amount of disinfectant after disinfection (safety after disinfection) are time-consuming and laborious. risk
