Description
Technical field
The present invention relates to the ancillary equipment in a kind of nephrosis medical field, it to be used for hospital's Blood Dialyzing Center, specifically one
Kind dialysis concentrate delivery system.
Background technique
Dialysis concentrate delivery system currently in use, operates using manual batch, and disposable concentrate is prepared,
It is stored in after filtering in large-scale fluid reservoir, each dialysis machine point of use is then transported to by pump and pipe-line system, as shown in Figure 5.
There is very big drawback in such manner of formulation, open manual batch list stirring and dissolving process just needs 1-2 hours, then moves on to again
Liquid storing barrel stored for future use, this activity will usually be ready in the previous day, and otherwise can not carry out normal dialysis within second day, cause
Prepared dialysis concentrate is just able at least in liquid storing barrel using and single for sodium bicarbonate for storage 10 hours or more
For the dialysis concentrate that the B powder of component is prepared, it is stored with two big drawbacks for a long time:
1, microorganism easily breeds that (YY0598 haemodialysis and associated treatment concentrate: total number of bacteria should be not more than 100CFU/
Ml, total number of fungi should be not more than 10CFU/ml, and Escherichia coli should must not detect) cause the dialysis to patient to endanger；
2, dialysis effective component bicarbonate ion is unstable, highly volatile (2NaHCO3→Na2CO3+CO2↑+H2O it) causes
The validity of analysis reduces.
There is concentrate delivery system currently in use again, feed flow part generallys use the following two kinds mode:
1, pump persistent loop liquor charging；
2, it pumps first to open daily and transfer pipeline is exhausted, exhaust 30 minutes or more, then termination of pumping was carried out using siphonic effect
Feed flow.
Above two feed liquid way, the drawbacks of being respectively present, are as follows:
For first way, since rear class liquid feeding pipeline generally uses bore 20mm, length is the pipeline of 200-300m, in this way
The hypertonia (usually in 0.4-0.5MPa) of local interface is resulted in, and remote interface insufficient pressure is even in the presence of no liquid
State causes kidney machine constantly to alarm, influences patient and effectively dialyse so that dialysate concentration fluctuates up and down in dialysis procedure；Meanwhile by
Interface evaporating, emitting, dripping or leaking of liquid or gas phenomenon is caused to happen occasionally in local interface hypertonia；What is more, and excessively high pressure can lead to kidney
The feed liquor parts damages of machine.
For the second way, 30 minutes evacuation times are long, time-consuming, and cannot be completely secured and accomplish pipeline liquid
(because the installation of rear class transfer pipeline will arrange according to room unit, window of moving into one's husband's household upon marriage crosses the positions such as wall and is intended to raise for body full
Or reduce, feel suffocated a little so existing in liquid feeding pipeline), cause into air in dialysis procedure, equipment alarm influences normal saturating
Analysis.
In addition, currently used concentrate delivery system uses chemical disinfection mode, disinfecting process is cumbersome, and disinfectant has
The residual volume detection (safety after disinfection) of disinfectant is time-consuming and laborious after imitating concentration (validity of disinfection) and sterilizing, to using
There are risks for person.
Based on this, spy of the present invention proposes a kind of dialysis concentrate delivery system, being capable of fast automatic preparation dialysis concentrate
