Abstract
The invention discloses a method for evacuating a dry powder barrel of a hemodialysis machine. The method comprises the steps that a negative pressure pump is kept rotating and a liquid tube B is taken out of a heating cavity, so that water in the heating cavity can not be sucked; a plunger pump is closed, a degassing valve is opened, and under the action of negative pressure between the negative pressure pump and a small-diameter connector, water in the dry powder barrel passes through a degassing cavity, the degassing valve and the negative pressure pump sequentially and is delivered to the heating cavity; the heating cavity is connected with the negative pressure pump through the small-diameter connector, the small-diameter connector is connected with an exhaust port of the degassing cavity through the degassing valve, a liquid inlet of the degassing cavity is connected with an outlet of the dry powder barrel, an inlet connected with the dry powder barrel is connected with the heating cavity through the liquid tube B, and a liquid outlet of the degassing cavity is connected with a liquid inlet of the plunger pump through a tube. According to the method, the dry powder barrel is evacuated through the negative pressure on a liquid channel, elements do not need to be additionally arranged on the liquid channel, and the method is easy to achieve and low in cost.
Description
Technical field
The present invention relates to the treatment technology of dry powder bucket in a kind of haemodialysis control unit, especially relate to a kind of dry powder bucket purging method of haemodialysis control unit.
Background technology
In the use procedure of dry powder bucket, its inside is can be water-filled.And after dry powder bucket is finished using, dry powder bucket need to be taken off and abandons from dry powder frame.Owing to having water in dry powder bucket, in the time that dry powder bucket is taken off from dry powder frame, water can spill from dry powder bucket, makes troubles to operator.
Therefore, before taking off dry powder bucket, need emptying dry powder bucket, the water in dry powder bucket is discharged, thus handled easily personnel.In current haemodialysis control unit, dry powder bucket emptier is to need to increase the control elements such as electromagnetic valve on Ye road could realize, and realizes cost higher.
Summary of the invention
For overcoming the defect of prior art, the present invention proposes a kind of dry powder bucket purging method of haemodialysis control unit without increasing control element and realizing simple.
The present invention adopts following technical scheme to realize: a kind of dry powder bucket purging method of haemodialysis control unit, and it comprises:
Keep negative pressure pump to rotate, B liquid pipe is taken out to the water that cannot suck in heating chamber from heating chamber;
Make that plunger displacement pump cuts out, air removing valve is opened, under the effect of the negative pressure between negative pressure pump and thin drive connector, make water in dry powder bucket successively through sending into heating chamber except air cavity, air removing valve, negative pressure pump;
Wherein, heating chamber connects negative pressure pump by thin drive connector, and thin drive connector connects the air vent except air cavity by air removing valve, and the liquid inlet of removing air cavity connects the outlet of dry powder bucket, and the entrance that connects dry powder bucket connects heating chamber by B liquid pipe, the liquid outlet that removes air cavity connects the liquid inlet of plunger displacement pump by pipeline.
Wherein, the dry powder bucket purging method of described haemodialysis control unit also comprises: the state that plunger displacement pump cuts out, air removing valve is opened is maintained and set after duration, finish the emptying process of dry powder bucket.
Wherein, setting duration is 10S.
Wherein, air removing valve is electromagnetic valve.
Compared with prior art, the present invention has following beneficial effect:
The present invention utilizes the negative pressure on liquid road to realize dry powder bucket emptying process, without increasing element on Ye road, realizes simply, realizes cost lower.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is schematic flow sheet of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention propose for haemodialysis control unit have simple in structure, realize lower-cost dry powder bucket emptier, it comprises: heating chamber 1; A liquid pipe 2 and B liquid pipe 3 in alternative implantation heating chamber 1 in liquid; B liquid pipe 3 is fastened on the entrance of the dry powder bucket 5 on dry powder frame 4, and the outlet of dry powder bucket 5 connects except the liquid inlet of air cavity 6 by pipeline, and connects the liquid inlet of plunger displacement pump 7 by pipeline except the liquid outlet of air cavity 6; And heating chamber 1 connects a negative pressure pump 8 by a thin drive connector 10, the air vent that this thin drive connector 10 connects except air cavity 6 by air removing valve 9.
When negative pressure pump 8 is worked, rotate, due to the obstruction of thin drive connector 10, make to there is the negative pressure of certain pressure size between negative pressure pump 8 and thin drive connector 10, thereby make the liquid in heating chamber 1 separated from the gas, reach the object of degasification.
In the time that haemodialysis control unit is normally worked, air removing valve 9 is closed, and by the rotation of plunger displacement pump 7, water is extracted out from heating chamber 1 by B liquid pipe 3, is mixed into mixed liquor through dry powder bucket 5 and the B powder in dry powder bucket 5, and mixed liquor is through sending from plunger displacement pump 7 except air cavity 6.
Wherein, air removing valve 9 is electromagnetic valve.
Shown in Fig. 2, the step that dry powder bucket 5 is carried out to emptying process specifically comprises:
Step S1, keep negative pressure pump 8 to rotate, B liquid pipe 3 is taken out from heating chamber 1, allowing it be exposed at outward in air can only air amount and cannot suck the water in heating chamber 1.
Step S2, make that plunger displacement pump 7 cuts out, air removing valve 9 is opened, under the effect of the negative pressure between negative pressure pump 8 and thin drive connector 10, the water in dry powder bucket 5 is successively through sending into heating chamber 1 except air cavity 6, air removing valve 9, negative pressure pump 8.
Step S3, the state that plunger displacement pump 7 cuts out, air removing valve 9 is opened is maintained and sets duration (such as 10S), set after duration in postponing, make air removing valve close and finish the emptying process of dry powder bucket 5.
Like this, the present invention utilizes the negative pressure between negative pressure pump 8 and thin drive connector 10 that the water in dry powder bucket 5 is blotted, and reaches the emptying object of dry powder bucket 5, and handled easily personnel take off dry powder bucket 5 from dry powder frame.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
