Abstract
The utility model provides a plasma separating bowl, which is composed of a bowl body, a cover of the bowl body, a core of the bowl body, an internal cover of the bowl body, a blood collecting pipe, a sealing bowl, a foundation ring, a ceramic ring and a lower cover of the bowl body. The utility model is characterized in that the bottom of the bowl body is provided with a concave platform, the core of the bowl body is arranged in the bowl body and a passage which the blood collecting pipe passes through is arranged on the core of the bowl body. A flow guide ring is arranged on the upper end of the blood collecting pipe. The internal cover of the bowl body is the shape of a reversed funnel. A feedback pipe on the internal cover of the bowl body is provided with an outlet. The ceramic ring, the foundation ring, the sealing bowl and the cover of the bowl body are sheathed on the feedback pipe. The ceramic ring is fixed on the lower cover of the bowl body which is bonded with the bowl body. When the utility model is used, blood flows into the bowl body from the blood collecting pipe. Under the action of centrifugal force, few constituents of the blood is destroyed. Plasma passes through an overflow passage to flow into a plasma bag from the outlet of the internal cover.
Description
The utility model relates to the auxiliary implement of the apparatus of extraction, processing or transferring body fluid.
When blood plasma is gathered by medical matters circle at present or biological products unit, traditional way be with extract from blood sampling person's health blood inject the common cup of centrifuge, utilize the proportion difference of heterogeneity in the blood, isolate blood plasma, red blood cell etc.The result of Chu Liing like this, blood constituent destroys more, if other composition of Plasma Pheresis/Apheresis Plasma can only be abandoned it, wastes bigger.
The utility model provides a kind of and the supporting plasma separation alms bowl of centrifuge, does not destroy blood constituent, obtain blood plasma after other composition can feed back blood sampling person easily.
Task of the present utility model is to form the plasma separation alms bowl with alms bowl body, alms bowl body lid, alms bowl body-centered, alms bowl inner cap, pipeline, obturating cup, foundation ring, porcelain ring, alms bowl body lower cover that following manner is finished.Be provided with concave station at the bottom of the alms bowl body, the alms bowl body-centered places the alms bowl body, the alms bowl body-centered is similar and hollow to the alms bowl shape, there is the passage that passes for the blood sampling pipeline at its center, the guide ring that a umbrella shape surface has protruding point is fixed in blood sampling pipeline upper end, alms bowl inner cap such as upside down funnel, form overflow channel with the guide ring on the blood sampling pipeline, pipeline on it is a feedback pipeline, its diameter and has outlet greater than the diameter of blood sampling pipeline, puts porcelain ring, foundation ring, obturating cup on this feedback pipeline successively, the porcelain ring is fixed on the alms bowl body and covers, and alms bowl body lower cover and alms bowl body are bonding.
Use the utility model, blood flows into from placing the blood sampling pipeline in the alms bowl body, under the centrifugal action of centrifuge, seldom destroys blood constituent, the overflow channel that blood plasma forms through alms bowl body inner cap and the guide ring of blood sampling on the pipeline flows in the plasma bags through the outlet of the feedback pipeline of alms bowl body inner cap.Other composition can be in centrifugal end after pipeline feeds back to blood sampling person, and this blood sampling is easier to be accepted by the people, can obtain how better blood plasma.
Fig. 1 structural representation of the present utility model
Below with reference to drawings and Examples the utility model is further described in detail.
Form by alms bowl body 1, alms bowl body lid 2, alms bowl body-centered 3, alms bowl body inner cap 4, blood sampling pipeline 5, obturating cup 6, foundation ring 7, porcelain ring 8, alms bowl body lower cover 9 with reference to Fig. 1 embodiment of the present utility model.1 end of alms bowl body, be provided with concave station, alms bowl body-centered 3 places alms bowl body 1, alms bowl body-centered 3 is similar and hollow to the alms bowl shape, there is the confession " passage that shape blood sampling pipeline 5 passes; the guide ring 10 that a umbrella shape surface has protruding point is fixed in blood sampling pipeline 5 upper ends; the overflow channel that forms with the funnel-form lid of alms bowl body inner cap 4; alms bowl body inner cap 4 is as upside down funnel; the feedback pipeline diameter on it is greater than the diameter of the pipeline of taking a blood sample; and have outlet at its center, be with porcelain ring 8 on this feedback pipeline successively, foundation ring 7, obturating cup 6, alms bowl body lid 2, porcelain ring 8 is fixed on the alms bowl body lower cover 9, and alms bowl body lower cover 9 is bonding with the alms bowl body.
Among the figure not cross-hatching be thin-wall construction.
During use, the plasma separation alms bowl places in the centrifuge, does not combine closely with the lid of centrifuge for protection plasma separation alms bowl is not damaged by pressure again by centrifuge cup, covers cover sealing ring, protective device at the alms bowl body.Take a blood sample from alms bowl body 1 inlet of pipeline 5 of blood enters to 1 end of alms bowl body, because the centrifugal action of centrifuge, the overflow channel that blood plasma forms through alms bowl body inner cap 4 and guide ring on the blood sampling pipeline 5 enters space that the feedback pipeline by blood sampling pipeline 5 outsides and alms bowl body inner cap 4 forms from the outlet inflow plasma bags of alms bowl body inner cap 4.Other composition can be in centrifugal end after blood sampling pipeline 5 feed back on blood sampling person's the arm.Seal close bowl 6 and stop the small amount that to cross alms bowl body inner cap 4, play sealing function with porcelain ring 8.Because the needs of processing technology may make, and blood sampling pipeline 5 is straight, the horizontal position of alms bowl body lid 2, pipeline 5, the section of tubing of alms bowl body inner cap 4 are integral bonding with straight pipeline again, have any different slightly with Fig. 1 in shape in the actual process.
