Description
Technical field
This utility model relates to a kind of blood collection device, particularly relates to a kind of bag for collecting cord blood.
Background technology
When Cord blood is fetal birth, ligature of the cord blood after section in Placenta Hominis and umbilical cord, all the components containing normal blood in Cord blood, comprises erythrocyte, leukocyte, platelet and blood plasma.Owing to containing abundant volume hemopoietic liver stem cells in Cord blood, can replace the use of bone marrow as transplanting, therefore Cord blood has great medical value.In umbilical blood, erythrocyte is opened and is accounted for larger score, before preserving, for reducing freeze volume, needing to separate a large amount of erythrocyte and only retaining the nucleated cell being rich in hematopoietic stem cell umbilical blood.
At present, need cord blood sample primary separation after to cord blood collection, its separation method be by hetastarch as fall heavy agent erythrocyte carried out fall heavy, make nucleated cell be in the upper strata of collected specimens, then carry out being separated the sample extracting and obtain being rich in hematopoietic stem cell to upper strata nucleated cell.But existing collection bag utilize hetastarch fall heavy after, when extracting upper strata nucleated cell, owing to extracting not exclusively when collection bag is easily out of shape and causes upper strata Cell sap to extract, cause the problem that hematopoietic stem cell is wasted; Cord blood is after carrying out initial gross separation collection simultaneously, the nucleated cell to gathering is needed to carry out antibacterial and Viral diagnosis, for deepfreeze is prepared, way is in the past by after bag for collecting cord blood carries out initial gross separation, be transferred in transfering bag by being separated the sample obtained, its antibacterial and Viral diagnosis chemically examine from new draw samples in transfering bag, and this kind of mode also exists the problem that complex operation and blood sample easily pollute.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of this utility model is just to provide a kind of bag for collecting cord blood, and object is to solve the upper strata Cell sap that traditional bag for collecting cord blood easily causes and extracts not exclusively and the problem of complex operation.
Its technical scheme is, bag for collecting cord blood, comprise blood bag and blood taking needle, blood bag is connected by the first conduit with blood taking needle, the end that on blood bag, the first conduit connects with blood bag is provided with puncture orifice, puncture orifice is the tubular structure of upper end sealing, the lower end of puncture orifice is connected with blood bag, the blood bag end relative in puncture orifice position is provided with thief hatch, blood bag is connected with chemical examination bag, connecting portion is provided with between blood bag and chemical examination bag, be connected by the second heat sealable conduit with the bottom of blood bag bottom chemical examination bag, heat seal mouth is provided with between second conduit and connecting portion.
Puncture orifice and thief hatch are oppositely arranged by this utility model, after the blood collected is separated, the red blood cell layer of natural subsidence is extracted out by thief hatch, after separation completes, cord blood sample is left in blood bag and chemical examination bag, then the second conduit is carried out heat seal and bag will be chemically examined being separated, blood in chemical examination bag is detected, after detection, blood shifts and preserves in blood bag, this process considerably increases the response rate of umbilicus blood nucleated cells, and enormously simplify the process of chemical examination and transfer.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, bag for collecting cord blood, comprise blood bag 1 and blood taking needle 2, blood bag 1 is connected by the first conduit 3 with blood taking needle 2, the end that on blood bag 1, first conduit 3 connects with blood bag 1 is provided with puncture orifice 4, puncture orifice 4 is for injecting sedimentation agents such as hydroxyethyl starch solutions, puncture orifice 4 is the tubular structure for upper end sealing, the lower end of puncture orifice 4 is connected with blood bag 1, blood bag 1 end relative in puncture orifice 4 position is provided with thief hatch 5, blood bag 1 is connected with chemical examination bag 6, connecting portion 7 is provided with between blood bag 1 and chemical examination bag 6, be connected by the second heat sealable conduit 8 with the bottom of blood bag 1 bottom chemical examination bag 6, be separated with between blood bag 1 for ease of chemical examination bag 6, heat seal mouth 9 is provided with between second conduit 8 and connecting portion 7.
In order to avoid when there is damage in blood taking needle 2, blood taking bag 1 still can use, said blood taking needle 2 comprises main blood taking needle and secondary blood taking needle, the first conduit 3 that main blood taking needle, secondary blood taking needle are connected with blood bag 1 is provided with threeway 10, the first conduit 3 between threeway 10 and main blood taking needle, secondary blood taking needle is respectively equipped with the first vessel clamp 11, and the first conduit 3 between threeway 10 and blood taking bag 1 is provided with the second vessel clamp 12.
When carrying out sedimentation layering to the umbilical blood collected, for convenience of layering with fixing, said puncture orifice 4 is respectively equipped with hanging hole 13 with blood bag 1 end at thief hatch 5 place.
Said chemical examination bag 6 is cylindrical cavity body structure, and be separated with blood bag 1 for ease of chemical examination bag 6, connecting portion 7 is provided with easy-torn line 14.
This utility model is when specifically using, decontrol the first vessel clamp 11 and the second vessel clamp 12, collection umbilical blood is carried out by main blood taking needle or secondary blood taking needle, enter chemical examination bag 6 according to law of connected vessels after blood enters blood bag 1 simultaneously, blood taking needle 2 is taken off after blood collection, first vessel clamp 11 and the second vessel clamp 12 are placed on corresponding first conduit 3, then heat seal sealing is carried out to the first conduit 3, also utilized upward by puncture sky top hanging hole 13 that blood bag 1 is carried out suspension to fix, cut off puncturing hole and inject hydroxyethyl starch solution, afterwards again heat seal sealing is carried out to puncturing hole, after waiting for a period of time, erythrocyte and nucleated cell liquid natural layering are now, erythrocyte is in lower floor, cut off thief hatch 5, lower floor's layer of red blood cells is extracted and leaves nucleated cell liquid, now blood bag 1 and chemical examination bag 6 in all by the nucleated cell liquid of remainder, heat seal sealing is carried out to the thief hatch 5 cut off, second conduit 8 is carried out to heat seal sealing and disconnects, and heat seal mouth 9 can facilitate heat seal machine to carry out heat seal to the second conduit 8, chemical examination bag 6 and blood bag 1 are torn along easy-torn line 14, antibacterial and Viral diagnosis is carried out to the sample in chemical examination bag 6, after detection, the nucleated cell liquid in blood bag 1 is shifted and preserved.
