Description

The dialysis solution for artificial kidney liquid dispensing device

Technical field

The present invention relates to field of medical appliances, is a kind of dialysis solution for artificial kidney liquid dispensing device that is applicable to that Blood Purification Center uses specifically.

Technical background

In recent years, the blood purification technology has obtained using widely and developing at medical field, and the therapeutic domain of blood purification is more and more wider, and the Blood Purification Center of many medical institutions is the established practice modelling, and workload is increasing.The work of preparation dialysis solution also more and more becomes the outstanding problem in the daily dialysis treatment work.Past is because workload is little, during the preparation dialysis solution, normally medicated powder is poured in one barrel, added a certain amount of water for dialysis, manually stir repeatedly with club then, so there are many drawbacks in operation, and the dialysis liquid measure of at first each preparation is less, generally can only prepare several a few decaliter dialysis solution that are raised to; The 2nd, waste time and energy, prepare a dialysis solution and will will exert oneself repeatedly to stir, fully dissolving of medicated powder with for a long time; The 3rd, the mass of dialysate that is made into is not good, because be manual stirring, the dosing bung is open, very easily pollutes, and the dialysis solution that is made into stirs uneven, its ingredient skewness in liquid; The 4th,, the packing trouble, the medicinal liquid for preparing is scooped out with one spoonful one spoonful on spoon, is sub-packed in the keg through funnel and uses for dialysis, and is loaded down with trivial details, time-consuming.Along with the formation of Blood Purification Center scale and the continuous increase of workload, need the dialysis liquid measure of preparation to reach several hectolitres at every turn, in addition more, require the time of dosing shorter, better quality, safety is stronger.

Summary of the invention

The present invention is for solving the problems that exist in the dialysis solution for artificial kidney process for preparation, invent a kind of fast, safely, save time, laborsaving, easy to use, can once prepare the dialysis solution for artificial kidney liquid dispensing device of a large amount of dialysis solution.

Technical scheme provided by the present invention is, a kind of dialysis solution for artificial kidney liquid dispensing device, comprise three-legged support, the dosing bucket, circulating pump, joystick control, filter, valve, automatic pressure reducing valve, temperature control system and connecting line, its special character is: the top of three-legged support is equipped with the dosing bucket, the dosing bucket is cylindrical, lid is arranged above, dosing bucket inner bottom surface is cone shape, cone tip opening, opening part has output pipe, many siphunculus are equipped with in the output pipe porch, and heating rod and temperature sensor are equipped with in the bottom in the dosing bucket, and dosing bucket internal upper part is equipped with annular and dashes the bucket pipeline, have several apertures above it, dosing bucket below is equipped with circulating pump, by pipeline dosing bucket and circulating pump is coupled together, and forms closed circuit, filter is housed on output pipe, between pump entry and outlet, automatic pressure reducing valve is installed, a plurality of valve controlling liquid is installed on the pipeline flows to joystick control controlling liquid temperature and circulating pump duty.

During use, a certain amount of medicated powder is added in the dosing bucket, dialysis is injected in the dosing bucket with pure water, water filling is to the scale of demarcating in advance, close and open corresponding valve by operating process, open the circulating pump on and off switch, liquid to circulating pump, returns the dosing bucket by the dosing bucket, form a closed circuit, liquid does not arrhea moving in closed circuit, and the liquid of getting back to simultaneously in the dosing bucket is rotated by certain orientation in the dosing bucket, plays mobile, stirring, blended effect.If water temperature is low excessively, influence the dissolubility of medicated powder, can open heating rod switch preheating dosing water.Through circulation in 5-10 minute, the dialysis solution preparation was finished.Through the conversion of valve, under the effect of circulating pump, the dialysis solution for preparing filters through filter, is sub-packed in the dialysis solution keg, uses for dialysis machine.

The present invention uses many siphunculus in exit, dosing bucket inner bottom tip, can effectively prevent to form whirlpool in the liquid circulation process, avoids air to be inhaled into circulating pump by the whirlpool center and forms air embolism; Between circulating pump is imported and exported, automatic pressure reducing valve is installed, can prevent in packing dialysis solution process, close the high pressure that the separatory valve forms owing to of short duration, promptly when the pressure at circulating-pump outlet place increases to certain value, automatic pressure reducing valve is opened decompression automatically, the balance that keep-ups pressure is with the protection liquid dispensing device; Joystick control and circulating pump, heating rod, temperature sensor link, the temperature of control circulating pump and heating rod switch, demonstration dosing water.
