The utility model discloses a disinfectant suction system for a hemodialysis machine. The system comprises a disinfectant bucket, an ultra-filtering pump, an electromagnetic valve D1 and an electromagnetic valve D2, wherein the disinfectant bucket is used for containing a disinfectant; an inlet of the ultra-filtering pump is connected with an outlet of the disinfectant bucket; the electromagnetic valve D1 is used for controlling a path between the outlet of the disinfectant bucket and air to be opened or closed, and is connected between the outlet of the disinfectant bucket and the air; and the electromagnetic valve D2 is used for controlling a path between the outlet of the disinfectant bucket and the inlet of the ultra-filtering pump to be opened or closed, and is connected between the outlet of the disinfectant bucket and the inlet of the ultra-filtering pump. A plurality of electromagnetic valves are used for combined control, so that the disinfectant can be prevented from being mistakenly sucked in a dialysis process, and damage to parts, which are impregnated by the disinfectant remaining in a pipeline, of the hemodialysis machine can also be avoided; the system has the advantages of simple structure and easiness for control; and the working reliability of the hemodialysis machine can be improved, and the service life of the hemodialysis machine can be prolonged.
Description
Technical field
This utility model relates to a kind of haemodialysis control unit, especially relates to a kind of disinfectant solution intake system of haemodialysis control unit.
Background technology
Haemodialysis control unit is after each dialysis operation is completed, need to suck the disinfectant solution disinfection from disinfection solution barrel, therefore need to arrange on the pipeline of haemodialysis control unit and control the device that sucks disinfectant solution, not only need to guarantee to suck disinfectant solution in disinfecting process, need also to prevent that mistake sucks disinfectant solution in dialysis procedure.
In existing haemodialysis control unit, controlling the device that sucks disinfectant solution is realized by baroque mechanical mechanism mostly, to adopt solenoid control to suck disinfectant solution in some haemodialysis control unit, but, if reveal at disinfectant solution inlet valve place's generation disinfectant solution, mistake can occur suck, safety is relatively poor, and part disinfectant solution long period of soaking is arranged on electromagnetic valve after the suction disinfectant solution is completed, electromagnetic valve is easily damaged, reduced service life and the reliability of haemodialysis control unit.
The utility model content
The utility model proposes a kind of simple in structure, disinfectant solution intake system of controlling easy haemodialysis control unit, the mistake that not only can prevent disinfectant solution in dialysis procedure sucks, the damage that the parts that can also avoid disinfectant solution to remain in parent's immersion haemodialysis control unit in pipeline cause.
This utility model adopts following technical scheme to realize: a kind of disinfectant solution intake system of haemodialysis control unit, and it comprises: the disinfection solution barrel that holds disinfectant solution; Ultrafiltrate pump, its entrance is connected with the outlet of disinfection solution barrel; Be used for control and open or close the outlet of disinfection solution barrel and the electromagnetic valve D1 of the path between air, this electromagnetic valve D1 is connected between the outlet and air of disinfection solution barrel; Be used for to control the electromagnetic valve D2 of the path between the entrance of the outlet that opens or closes disinfection solution barrel and ultrafiltrate pump, this electromagnetic valve D2 is connected between the entrance of the outlet of disinfection solution barrel and ultrafiltrate pump.
Wherein, connect the electromagnetic valve D4 that controls discharge opeing on the ultrafiltration delivery side of pump.
Wherein, the entrance of ultrafiltrate pump connects the ultrafiltration pipeline by electromagnetic valve D3.
Compared with prior art, the utlity model has following beneficial effect:
This utility model jointly controls by a plurality of electromagnetic valves, the mistake that not only can prevent disinfectant solution in dialysis procedure sucks, the damage that the parts that can also avoid disinfectant solution to remain in parent's immersion haemodialysis control unit in pipeline cause, have simple in structure, control easy advantage, and can improve functional reliability and the service life of haemodialysis control unit.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic flow sheet of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model proposes a kind of disinfectant solution intake system of haemodialysis control unit, it comprises: hold the disinfection solution barrel 1 of disinfectant solution, the outlet of disinfection solution barrel 1 is connected between electromagnetic valve D1 and electromagnetic valve D2, and the end of electromagnetic valve D1 is directly exposed in air by pipeline 3; Electromagnetic valve D2 connects ultrafiltration pipeline 4 by electromagnetic valve D3, and is connected the entrance of ultrafiltrate pump 2 between electromagnetic valve D2 and electromagnetic valve D3, and the outlet of ultrafiltrate pump 2 connects main water pipeline 5, and electromagnetic valve D4 connection discharge pipe line 6 is passed through in the outlet of ultrafiltrate pump 2.
When normal dialysis, make that electromagnetic valve D1 opens, electromagnetic valve D2 closes, electromagnetic valve D3 opens, electromagnetic valve D4 opens, like this, because the direct ingress of air of electromagnetic valve D1 is passed through in the outlet of disinfection solution barrel 1, even electromagnetic valve D2 occurs to leak or fault, ultrafiltrate pump 2 also can't be from disinfection solution barrel 1 sucking-off disinfectant solution.Simultaneously, the liquid from ultrafiltration pipeline 4 flows through enters ultrafiltrate pump 2 through electromagnetic valve D3, together discharges through electromagnetic valve D4 with the liquid of main water pipeline 5.
In conjunction with shown in Figure 2, the step that the liquid that carries out disinfection sucks comprises:
Step S1, make that electromagnetic valve D1 closes, electromagnetic valve D2 opens, electromagnetic valve D3 closes, electromagnetic valve D4 closes.
Step S2, ultrafiltrate pump 2 work, from disinfection solution barrel 1 sucking-off disinfectant solution, and disinfectant solution is expelled to the sterilization that circulates of main water pipeline 5 from the outlet of ultrafiltrate pump 2.
Step S3, after drawing disinfectant solution and completing, electromagnetic valve D1 is opened, make the disinfectant solution in pipeline between ultrafiltrate pump 2 entrances that is exported to of disinfection solution barrel 1, reflux under action of gravity.
After step S4, electromagnetic valve D1 open, control ultrafiltrate pump 2 postpone the work scheduled durations (such as, inhale the 5-10 chamber for making ultrafiltrate pump 2), the disinfectant solution that remains in electromagnetic valve D2 position is siphoned away, thereby preventing that medicining liquid dipping electromagnetic valve D2 from causing damages or lost efficacy.
Step S5, electromagnetic valve D2 is closed, complete the whole process that disinfectant solution sucks.
To sum up, this utility model jointly controls by a plurality of electromagnetic valves, the mistake that not only can prevent disinfectant solution in dialysis procedure sucks, the damage that the parts that can also avoid disinfectant solution to remain in parent's immersion haemodialysis control unit in pipeline cause, have simple in structure, control easy advantage, and can improve functional reliability and the service life of haemodialysis control unit.
The above is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
