On solenoid valve, it is easily damaged solenoid valve, reduces the service life and reliability of haemodialysis control unit.
Summary of the invention
The present invention proposes that a kind of structure is simple, controls the thimerosal inhalation method and system of easy haemodialysis control unit, no
It can only prevent the mistake of thimerosal in dialysis procedure from sucking, thimerosal can also be avoided to remain in parent in pipeline and impregnate haemodialysis
It is damaged caused by the component of machine.
The present invention adopts the following technical scheme that realization: a kind of thimerosal inhalation method of haemodialysis control unit comprising step:
The access between the outlet and air for holding the disinfection solution barrel of thimerosal is closed, and opens going out for disinfection solution barrel
Access between mouth and the entrance of ultrafiltrate pump；
It controls ultrafiltration pump work and draws thimerosal from disinfection solution barrel；
The access between the outlet and air of disinfection solution barrel is opened, and after control ultrafiltrate pump delay work scheduled duration, is closed
Close the access between the outlet of disinfection solution barrel and the entrance of ultrafiltrate pump.
Wherein, solenoid valve D1 is set on the access between the outlet and air of disinfection solution barrel, is beaten by controlling solenoid valve D1
On or off is closed to control the access opened or closed between the outlet of disinfection solution barrel and air.
Wherein, solenoid valve D2 is set on the access between the outlet of disinfection solution barrel and the entrance of ultrafiltrate pump, passes through control electricity
Magnet valve D2 open or close control open or close disinfection solution barrel outlet and ultrafiltrate pump entrance between access.
Wherein, the solenoid valve D4 of control drain is connected in the outlet of ultrafiltrate pump.
Wherein, the entrance of ultrafiltrate pump passes through solenoid valve D3 connection ultrafiltration pipeline.
A kind of thimerosal intake system of haemodialysis control unit comprising: the disinfection solution barrel of thimerosal is held, disinfection solution barrel
Solenoid valve D1 is connected on access between outlet and air；On access between the outlet of ultrafiltrate pump, entrance and disinfection solution barrel
Connect solenoid valve D2；
It controls solenoid valve D1 to close and solenoid valve D2 opening, makes ultrafiltration pump work from disinfection solution barrel absorption thimerosal, and in
After drawing thimerosal, control solenoid valve D2 is closed after control solenoid valve D1 makes ultrafiltrate pump postpone work scheduled duration after opening
It closes.
Compared with prior art, the invention has the following beneficial effects:
The present invention is jointly controlled by multiple solenoid valves, can not only prevent the mistake of thimerosal in dialysis procedure from sucking,
Thimerosal can also be avoided to remain in parent in pipeline and impregnate damage caused by the component of haemodialysis control unit, control simple with structure
Simple advantage is made, and the functional reliability and service life of haemodialysis control unit can be improved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is flow diagram of the invention.
Specific embodiment
As shown in Figure 1, the present invention proposes a kind of thimerosal intake system of haemodialysis control unit comprising: hold thimerosal
Disinfection solution barrel 1, the outlet of disinfection solution barrel 1 is connected between solenoid valve D1 and solenoid valve D2, and one end of solenoid valve D1 passes through
Pipeline 3 is directly exposed to air；Solenoid valve D2 passes through solenoid valve D3 connection ultrafiltration pipeline 4, and solenoid valve D2 and solenoid valve D3
Between connect the entrance of ultrafiltrate pump 2, and the outlet of ultrafiltrate pump 2 connects main water pipeline 5, and the outlet of ultrafiltrate pump 2 passes through electromagnetism
Valve D4 connection discharge pipe line 6.
In normal dialysis, open solenoid valve D1, solenoid valve D2 closing, solenoid valve D3 opening, solenoid valve D4 opening, this
Sample, even if leakage or failure occur for solenoid valve D2, surpasses since the outlet of disinfection solution barrel 1 is by the direct ingress of air of solenoid valve D1
Also thimerosal can not be sucked out from disinfection solution barrel 1 in filter pump 2.Meanwhile the liquid flowed through from ultrafiltration pipeline 4, enter by solenoid valve D3
Ultrafiltrate pump 2 passes through solenoid valve D4 discharge together with the liquid of main water pipeline 5.
As shown in connection with fig. 2, the liquid that carries out disinfection suck the step of include:
Step S1, close solenoid valve D1, solenoid valve D2 is opened, solenoid valve D3 is closed, solenoid valve D4 is closed.
Step S2, ultrafiltrate pump 2 works, and thimerosal is sucked out from disinfection solution barrel 1, and thimerosal is discharged from the outlet of ultrafiltrate pump 2
Circulation disinfection is carried out to main water pipeline 5.
Step S3, after the completion of drawing thimerosal, solenoid valve D1 is opened, the ultrafiltrate pump 2 that is exported to of disinfection solution barrel 1 is entered
Thimerosal between mouthful in pipeline, flows back under the effect of gravity.
Step S4, after solenoid valve D1 is opened, control ultrafiltrate pump 2 postpones work scheduled duration (for example, to inhale ultrafiltrate pump 2
5-10 chamber), the thimerosal for remaining in the position solenoid valve D2 is siphoned away, thus prevent medicining liquid dipping solenoid valve D2 damage or
Failure.
Step S5, solenoid valve D2 is closed, completes the whole process of thimerosal sucking.
To sum up, the present invention jointly controlling by multiple solenoid valves, can not only prevent the mistake of thimerosal in dialysis procedure
Sucking can also avoid thimerosal from remaining in parent in pipeline and impregnate damage caused by the component of haemodialysis control unit, have structure letter
Advantage single, control is simple, and the functional reliability and service life of haemodialysis control unit can be improved.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
