Abstract
The utility model discloses a dry powder barrel preflushing device used for a hemodialysis machine. The dry powder barrel preflushing device comprises a heating cavity, a liquid inlet end is connected with the heating cavity through a pipeline, a liquid outlet end is connected with a negative pressure pump of the heating cavity through a thin joint, a liquid outlet end of the negative pressure pump is connected with an outlet of a dry powder barrel through an air removing valve and an air removing cavity in sequence, and an inlet of the dry powder barrel is connected with the heating cavity through a B liquid tube. According to the dry powder barrel preflushing device, the reversion of the negative pressure pump on a liquid path is utilized to perform reverse preflushing treatment on the dry powder barrel, no element is additionally arranged on the liquid path, and the dry powder barrel preflushing device has the advantages of simple structure and lower implementation cost.
Description
Technical field
This utility model relates to a kind of parts of haemodialysis control unit, especially relates to a kind of pre-flushing device of dry powder bucket for haemodialysis control unit.
Background technology
Use B dried bean noodles powder bucket (to be called again " B dry powder bucket " in haemodialysis control unit, the application is referred to as " dry powder bucket ") during hemodialysis in, because the manufacturing firm of dry powder bucket is numerous, quality is uneven, the unsettled phenomenon of electrical conductivity easily appears in some second-rate dry powder buckets, thus impact dialysis quality.
In order to address this problem, can now the dry powder bucket be carried out pre-punching and process before dialysis, namely first will be full of water in the dry powder bucket, then use after adding the B powder, can solve the above-mentioned unsettled problem of electrical conductivity that occurs.
But in present haemodialysis control unit, if will realize that the dry powder bucket rushes processing in advance, need to increase the control element such as electromagnetic valve on the liquid road could realize, realizes that cost is higher.
The utility model content
For overcoming the defective of prior art, the utility model proposes a kind of simple in structure for haemodialysis control unit, realize the pre-flushing device of lower-cost dry powder bucket.
This utility model adopts following technical scheme to realize: a kind of pre-flushing device of dry powder bucket for haemodialysis control unit, and it comprises: heating chamber; Liquid feeding end connects heating chamber, liquid outlet by pipeline and connects the negative pressure pump of heating chamber by thin drive connector; And the liquid outlet of negative pressure pump passes through successively air removing valve, connects the outlet of dry powder bucket except air cavity, and the entrance of dry powder bucket connects heating chamber by B liquid pipe.
Wherein, air removing valve is electromagnetic valve.
Compared with prior art, the utlity model has following beneficial effect:
This utility model utilize the negative pressure pump counter-rotating on the liquid road realize to the dry powder bucket oppositely pre-bath process, need not increases element on the liquid road, simple in structure, realizes that cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model proposes for haemodialysis control unit have simple in structure, realize the pre-flushing device of lower-cost dry powder bucket, 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 liquid inlet except 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, this thin drive connector 10 by air removing valve 9 (such as, air removing valve 9 be electromagnetic valve) connect the air vent that removes air cavity 6.
Forward rotation during negative pressure pump 8 work due to the obstruction of thin drive connector 10, makes between negative pressure pump 8 and thin drive connector 10 to have the negative pressure of certain pressure size, thereby makes the liquid in heating chamber 1 separated from the gas, reaches the purpose of degasification.
When haemodialysis control unit worked, air removing valve 9 was closed, and by the rotation of plunger displacement pump 7, water is extracted out from heating chamber 1 by B liquid pipe 3, and the B powder interior through dry powder bucket 5 and dry powder bucket 5 is mixed into mixed liquor, and mixed liquor is through sending from plunger displacement pump 7 except air cavity 6.
When needs carry out pre-punching processing to dry powder bucket 5, make negative pressure pump 8 backward rotation, air removing valve 9 is opened and plunger displacement pump 7 is cut out, current direction negative pressure pump 8 in heating chamber 1 is divided into two-way through after negative pressure pump 8: wherein one the tunnel flow back to heating chamber 1 through meticulous drive connector 10; Another road is through flowing to dry powder bucket 5 except air cavity 6.When going up the position in the water in visual dry powder bucket 5 reaches, control negative pressure pump 8 and stop operating, can complete the pre-punching of dry powder bucket 5 is processed.
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.
Claims (2)
1. the pre-flushing device of dry powder bucket that is used for haemodialysis control unit, is characterized in that, comprising: heating chamber; Liquid feeding end connects heating chamber, liquid outlet by pipeline and connects the negative pressure pump of heating chamber by thin drive connector; And the liquid outlet of negative pressure pump passes through successively air removing valve, connects the outlet of dry powder bucket except air cavity, and the entrance of dry powder bucket connects heating chamber by B liquid pipe.
2. be used for according to claim 1 the pre-flushing device of dry powder bucket of haemodialysis control unit, it is characterized in that, air removing valve is electromagnetic valve.
