Abstract
The utility model relates to the field of medical equipment, especially, relate to a bleeding of umbilicus collection separation blood bag. The utility model provides a bleeding of umbilicus collection separation blood bag adopts two inserting needles: the blood sampling bag is perhaps changed, save time and cost to the syringe needle that does not need to be changed when the unsuccessful or syringe needle of puncture once blocks up. The pinhole footpath is thick: increase blood sampling speed, reduce blood and block up, guarantee the bleeding of the umbilicus quality. Can be upright oval bottom and elliptical bag body lower part, the middle part is narrow slightly, and top is wide flat, and the ultra -clean bench bag can upright be placed to the blood sampling during separation, need not hang or shift out other container. Cell, the harm of less cell are collected to the opening of upright uncapping, pipette or the pasteur pipet of facilitating the use. Bag body middle part is narrow slightly, can enlarge the candidate stem cell layer relatively, does benefit to the collection cell, reduces the cell loss. Gather disengaging process from the bleeding of the umbilicus, need not shift to other containers the pollution abatement risk.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of cord blood collection and is separated blood bag.
Background technology
Medical research in the last thirty years finds, containing very abundant hematopoietic stem cell (HSC) in Cord blood, human body hemopoietic and immune system can be rebuild, can be used for hematopoietic stem cell transplantation, treatment blood system, immune system, and hereditary metabolic disorders and congenital diseases.Therefore, Cord blood has become the important sources of hematopoietic stem cell, has been widely used in clinical, is valuable human biological's resource.In order to ensure to be applied to clinical umbilical blood not microbial contamination, except adopting advanced person, reliably antibacterial culturing detection system detection technique, the pollution rate how strictly controlling cord blood collection and separation process microorganism is of crucial importance.
Whether successfully umbilical blood from collecting utilization, and successfully whether the conclusive first step to gather, then to separation process.Gatherer process needs to keep aseptic, and separation process needs omnidistance sterile working especially.According to statistics, open collection pollution rate up to 12.5%, seal be then reduced to 3.3%, after being separated, in Cell sap, antibacterial and fungus recall rate are respectively: closed is up to 8.0% and 2.0%, open, is 12% and 2.0%.In blood sampling volume, the previous common blood taking bag successful acquisition umbilical blood amount of order is approximately 70mL, in a lot of situation, the umbilical blood amount of a baby can reach 200mL, the major reason affecting blood sampling volume is gatherer process overlong time, blood coagulation, gets lodged in pin hole position, causes blood sampling volume even deficiency on the low side etc.Further, current blood taking bag needs to hang mostly, uses very inconvenient in blood collection procedure.Further, after umbilical blood is separated, topmost one deck is water and blood plasma, and intermediate layer is hematopoietic stem cell layer, and bottom one deck is other heteroproteose cell layers such as erythrocyte.Wide in the middle part of existing blood bag bag, the hematopoietic stem cell layer after separation is thinner, is unfavorable for the collection of cell.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of cord blood collection to be separated blood bag.This blood bag is easy to use, mustn't transfer to other containers and just can be separated, and blood sampling volume abundance can effective isolating hematopoietic stem cells.
Cord blood collection that this utility model provides is separated blood bag, be provided with in bag (14) top blood transfusion socket (1), can opening neck (3) and bag conduit (4);
Be oval bottom bag, middle part is shunk, and top is wide flat;
Son (2) of can uncapping can be configured with by opening neck (3);

What this utility model provided can coordinate with son of can uncapping by opening neck, can be uncapped by outward turning mode.Pipet easy to use or pasteur pipet collecting cell, less primary cellular defect and pollution.
After umbilical blood is separated, topmost one deck is water and blood plasma, intermediate layer is hematopoietic stem cell layer, bottom one deck is other heteroproteose cell layers such as erythrocyte, the cord blood collection that this utility model provides is separated blood bag, slightly narrow in the middle part of bag, can relatively amplify hematopoietic stem cell layer height, be beneficial to collecting cell, reduce cell depletion.
As preferably, the first blood taking needle arranges the first syringe needle (11) and the first syringe needle handle (9); Described first syringe needle (11) configures the first needle protective cap (10); Second blood taking needle arranges the second syringe needle (11 ') and the second syringe needle handle (9 '); Described second syringe needle (11 ') configures the second needle protective cap (10 ').
Preferably, the internal diameter of the first syringe needle (11) and the second syringe needle (11 ') is 2.0mm.
As preferably, the length of bag conduit is 20cm.
Blood sampling conduit connects the conduit of two blood taking needles at 20cm place by tee T, in case puncture failure or blood coagulation blocking pin hole; Increase thick blood taking needle aperture, blood sampling speed can be increased, reduce blood blocking, ensure umbilical blood quality.
As preferably, the diameter of blood transfusion socket (1) is 0.5cm.
As preferably, can the diameter of opening neck (3) be 2.0cm.
As preferably, in the middle part of bag with bag bottom diameter than being 1:2 ~ 3.
Preferably, in the middle part of bag with bag bottom diameter than for 1:2.5.
Preferred, bag mid diameter is 4.8cm; Base diameter is 12cm, the wide 10cm in top.
As preferably, bottom bag (14), base (13) is set.
As preferably, the volume of bag is 250mL.
Cord blood collection that this utility model provides is separated blood bag, be provided with in bag (14) top blood transfusion socket (1), can opening neck (3) and bag conduit (4); Be oval bottom bag, middle part is shunk, and top is wide flat;
Son (2) of can uncapping can be configured with by opening neck (3); Bag conduit (4) connects the first needle catheter (7) and the second needle catheter (7 ') through threeway (6); First needle catheter connects the first blood taking needle (12); Second needle catheter connects the second blood taking needle (12 '); Bag conduit (4), the first needle catheter (7) and the second needle catheter (7 ') configuration flow-stopping clip.The cord blood collection that this utility model provides is separated blood bag, adopts two inserting needles: do not need when one-time puncture is unsuccessful or syringe needle blocks to change syringe needle, or change blood taking bag, save time and cost.Pin hole footpath is thick: increase blood sampling speed, reduces blood blocking, ensures umbilical blood quality.Erectile oval bottom and oval bag bottom, middle part is slightly narrow, and upper part is wide flat, and during separation, blood taking bag can uprightly be placed on super-clean bench, does not need hang or migrate out other container.Uprightly to uncap opening, pipet easy to use or pasteur pipet collecting cell, less primary cellular defect.Slightly narrow in the middle part of bag, can relatively amplify hematopoietic stem cell layer, be beneficial to collecting cell, reduce cell depletion.From cord blood collection to separation process, do not need to be transferred to other containers, decreasing pollution risk.
