Abstract
The utility model relates to the technical field of medical devices, in particular to a fluid infusion circuit for blood purification. The fluid infusion circuit comprises a straight flow pipeline and a weighing pipeline, and is characterized in that one end of the weighing pipeline is connected with the middle section of the straight flow pipeline, a transfer cavity is arranged at the other end of the weighing pipeline, and a pinch valve is arranged on the weighing pipeline. The trend of the fluid infusion circuit is controlled by the pinch valve, blood replacement and hemofiltration can be completed by the fluid infusion circuit, waste of blood plasma is prevented, the operation time is shortened, and consumption of consumables is reduced.
Description
Technical field
This utility model relates to the medical device technical field, particularly a kind of blood purification fluid infusion loop.
Background technology
Present abiotic type artificial liver therapy is widely used in clinical medicine, and method commonly used comprises plasmapheresis, blood plasma absorption, hemodialysis, hemofiltration, albumin dialysis absorption etc.
Wherein continuing the same patient of pipeline that formula hemofiltration therapy low mates can the displacement of advanced promoting the circulation of blood slurry, the whole blood that gathers the patient is isolated patient's hemocyte by plasma separator, hemocyte and the blood plasma that replenishes are failed back in the patient body by replenishing line, and useless blood plasma is discharged by the road; After finishing, plasmapheresis carrying out hemofiltration, plasma separator is replaced with transfusion filters; The displacement liquid measure of replenishing when blood plasma filters is larger, and directly input can cause blood samples of patients discrepancy amount unbalance, could be in fluid infusion loop input patient body after displacement liquid is weighed, so need to increase the link of weighing in the fluid infusion loop; The fluid infusion loop of using in the former separating plasma displacement and the blood plasma in the loop go out of use, and have the waste of consumptive material and blood plasma.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and a kind of blood purification fluid infusion loop simple in structure, easy to use is provided.
For achieving the above object, this utility model is by the following technical solutions:
A kind of blood purification fluid infusion described in the utility model loop comprises the direct current pipeline, the pipeline of weighing, and it is characterized in that: described pipeline one end of weighing is connected with direct current pipeline stage casing, and the pipeline other end of weighing is provided with transfer chamber, and the described pipeline of weighing is provided with the folder valve.
Further, described transfer chamber is provided with the one-way air inlet mouth.
This utility model beneficial effect is: this utility model uses a cover fluid infusion loop to finish blood replacing and hemofiltration by folder valve control fluid infusion loop trend, has avoided the waste of blood plasma, has reduced the operating time, has reduced the use of consumptive material.
Description of drawings
Fig. 1 is overall structure sketch map of the present utility model.
Among the figure:
1, direct current pipeline; 2, the pipeline of weighing; 3, folder valve; 4, transfer chamber;
41, one-way air inlet mouth.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
A kind of blood purification fluid infusion described in the utility model loop comprises direct current pipeline 1, the pipeline 2 of weighing, and described pipeline 2 one ends of weighing are connected with direct current pipeline 1 stage casing, and pipeline 2 other ends of weighing are provided with transfer chamber 4, and the described pipeline 2 of weighing is provided with folder valve 3.
Above-mentioned parts are this utility model agent structure.
Described transfer chamber 4 is provided with one-way air inlet mouth 41.
Operation principle: during plasmapheresis, direct current pipeline 1 import in the fluid infusion loop is connected with the blood plasma bag, 1 outlet of direct current pipeline is connected with the fluid infusion pump, folder valve 3 cuts out, blood plasma is driven by direct current pipeline 1 by the fluid infusion pump and transmits to plasma separator, after displacement is finished blood plasma is guaranteed replacement into the displacement liquid bag, separator is replaced with filter; Open folder valve 3, displacement liquid is affected by gravity and enters transfer chamber 4, and transfer chamber 4 rear direct current pipeline 1 import of weighing is closed, and the displacement liquids that the fluid infusion pump drives in the transfer chamber 4 transmit to filter.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of this utility model patent claim, feature and principle change or modify, is included in this utility model patent claim.
