Description
Technical field
It the utility model is related to a kind of medicine equipment, more particularly to a kind of transfusion bags for candidate stem cell.
Background technology
HSCT has turned into a kind of specification of the diseases such as radical cure malignant hematologic disease, alpastic anemia at present
Change treatment means, application is gradually expanding.In migration process, peripheral stem cell collecting quantity is that transplanting is successfully closed
Key, its main component are CD34+ cells, and enough CD34+ cells input patient's body could play an important role to hematopoietic reconstitution.
So how to ensure the safe and effective smoothly infusion of stem cell, complication is avoided or reduced, is directly connected to the success or failure of transplanting.
In practice, a small amount of stem cell suspension of residual in the candidate stem cell transfusion bags after terminating is transfused, need to be inhaled with syringe
Infusion bag is implemented to rinse after entering physiological saline, is further continued for after the candidate stem cell being adhered on transfusion bags inwall is rinsed
Transfusion.So repeatedly, the loss of stem cell is reduced as far as possible.But because transfusion bags can not puncture repeatedly, easily cause outside stem cell
Leakage, adds pollution probability.Workload and the operating time of nurse is also increased simultaneously.
Utility model content
In view of the above problems, the utility model is directed to a kind of transfusion bags dedicated for candidate stem cell infusion, punching
Candidate stem cell caused by puncturing can be avoided to leak outside during washing, and external contamination can be avoided completely.
Transfusion bags of the present utility model for candidate stem cell, it includes：Bag of saline, candidate stem cell bag；
Bag of saline is used to accommodate the physiological saline for being used for rinsing candidate stem cell bag；Candidate stem cell bag is treated defeated for receiving
The candidate stem cell of note；
Candidate stem cell bag is located at below bag of saline；
The lower end of bag of saline is formed with ring body, formed with through hole in ring body side wall；Ring body lower end is formed with cylinder, cylinder envelope
The lower end of closed loop body；
Candidate stem cell bag upper end is formed with annular access port；
The external diameter of the cylinder of bag of saline lower end corresponds to the internal diameter of the annular access port of candidate stem cell bag upper end；The post
Body can insert in the annular access port fluid tightly, thus separate bag of saline and candidate stem cell bag, and the cylinder can also be from
Extracted in the annular access port, thus connect bag of saline and candidate stem cell bag；
Telescopic bellows is further provided between bag of saline and candidate stem cell bag；The upper end of bellows is connected to
The lower end of bag of saline, lower end is connected in the upper periphery of the annular access port of candidate stem cell bag upper end, thus by bag of saline
The upper shed of annular access port of ring body, cylinder and candidate stem cell bag surround wherein, to be hedged off from the outer world.
Preferably, the length of the cylinder is equal to the length of the annular access port, thus, described in cylinder insertion
During annular access port, the bottom of the cylinder flushes with the bottom of the annular access port.
Glued by the transfusion bags of the present utility model for candidate stem cell, it is necessary to rinse on the inwall of candidate stem cell bag
During attached candidate stem cell, cylinder is extracted from ring-type access port, the physiological saline in bag of saline is put into candidate stem cell bag
In, without being punctured to candidate stem cell bag, stem cell will not be caused to leak outside；Due to the encirclement of bellows, even more may be used
To avoid external contamination completely.

Embodiment
Below, it is described in detail with reference to Fig. 1-6 pairs of transfusion bags of the present utility model for candidate stem cell.
Transfusion bags of the present utility model for candidate stem cell, it includes：Bag of saline 10, candidate stem cell bag 20.
Bag of saline 10 is used to accommodate the physiological saline for being used for rinsing candidate stem cell bag 20；Candidate stem cell bag 20 is used for
Accommodate candidate stem cell to be transfused.
Candidate stem cell bag 20 is located at the lower section of bag of saline 10.
The lower end of bag of saline 10 is formed with ring body 13, formed with through hole 14 in the side wall of ring body 13；The lower end of ring body 13 formed with
Cylinder 12, cylinder 12 close the lower end of ring body 13.
The upper end of candidate stem cell bag 20 is formed with annular access port 21.
The external diameter of the cylinder 12 of the lower end of bag of saline 10 corresponds to the interior of the annular access port 21 of the upper end of candidate stem cell bag 20
Footpath.Cylinder 12 can insert in annular access port 21 fluid tightly, thus separate bag of saline 10 and candidate stem cell bag 20.Cylinder
12 can also extract from annular access port 21, thus connect bag of saline 10 and candidate stem cell bag 20.
Telescopic bellows 11 is further provided between bag of saline 10 and candidate stem cell bag 20.Bellows 11 it is upper
End is connected to the lower end of bag of saline 10, and lower end is connected to the upper periphery of the annular access port 21 of the upper end of candidate stem cell bag 20
On, thus the upper shed of the annular access port 21 of the ring body 13 of bag of saline 10, cylinder 12 and candidate stem cell bag 20 is surrounded
Wherein, to be hedged off from the outer world.
The length of cylinder 12 is equal to the length of annular access port 21, thus, when cylinder 12 inserts annular access port 21, post
The bottom of body 12 flushes with the bottom of annular access port 21.
When carrying out the infusion of candidate stem cell, cylinder is inserted in annular access port, thus block bag of saline and hematopoiesis
Passage between stem cell bag, now bellows be in contraction state, as shown in Figure 2.Needing to candidate stem cell bag inwall
When the candidate stem cell of upper adhesion is rinsed, the passage between plug bag of saline and candidate stem cell bag is opened, as shown in figure 1,
Now, the physiological saline in bag of saline enters in bellows via after ring body, through hole, is then made by the entrance of annular access port
In hemocytoblast bag.The passage between bag of saline and candidate stem cell bag is blocked again, rocks candidate stem cell bag, you can with entering
The physiological saline entered in candidate stem cell bag is rinsed to the candidate stem cell being adhered on inwall, will be flushed into physiological saline
Candidate stem cell carry out continuing to be transfused.If desired, can be with iterative cycles aforesaid operations.
