Embodiment
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, below in conjunction with accompanying drawing, to this
The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.
As shown in Figure 1-2, described stem cell filter separator include middle blood bag 1, left side blood bag 2, right side blood bag 3,
Drainage tube I 4, drainage tube II 5, probe tube 6, drainage needle 7, filter 8, filter screen 9, drainage tube III 10, piston 11, drainage tube IV
12。
The filter 8 is provided with drainage needle 7, is internally provided with filter screen 9, its bottom passes through drainage tube III 10 and piston 11
Right-hand member connection, the right-hand member of piston 11 connected by drainage tube IV 12 with the top of middle blood bag 1, drainage tube III 10 and drainage tube
Check valve is respectively equipped with IV 12, drainage tube III 10 turns on from filter 8 to the direction of piston 11, drainage tube IV 12 from piston 11 to
The middle direction of blood bag 1 conducting；The left side and right side of the middle blood bag 1 are respectively equipped with left side blood bag 2 and right side blood bag 3, middle
The top of blood bag 1 is connected by drainage tube I 4 with left side blood bag 2, and its bottom is connected by drainage tube II 5 with right side blood bag 3, is drawn
Check valve is equipped with flow tube I 4 and drainage tube II 5 and blood stops valve, the middle top of blood bag 1 is provided with probe tube 6, set on probe tube 6
There is rubber stopper.
In use, being connected filter 8 with bleeding of the umbilicus bag to be separated by drainage needle 7, bleeding of the umbilicus can be drawn using piston 11
Enter the neutralization of filter 8 to be transported in middle blood bag 1, it is miscellaneous that the filter screen 9 in filter 8 can filter the clot such as condensed in bleeding of the umbilicus
Matter, meanwhile, pass through at the uniform velocity push-and-pull piston 11 so that bleeding of the umbilicus can be filtered uniformly by filter screen 9, and smoothly be transported to middle blood
In bag 1, it is not necessary to which artificial extruding blood bag can complete the filtering and transfer of bleeding of the umbilicus, easy to operate.
After middle blood bag 1 is full of bleeding of the umbilicus, simultaneously heat seal drainage tube IV 12 is cut, hydroxyethyl starch solution is passed through into probe tube
Among 6 injections in blood bag 1, middle blood bag 1, left side blood bag 2 and the entirety of right side blood bag 3 are subjected to first time centrifugation after fully mixing,
Bleeding of the umbilicus among after the completion of centrifugation in blood bag 1 is divided into three layers, and upper strata is blood plasma, and middle level is umbilical cord blood hematopoietic stem cell, and lower floor is
Red blood cell, now by controlling the blood on drainage tube I 4 and drainage tube II 5 to stop valve, upper plasma is squeezed into the blood bag 2 of left side, incited somebody to action
Lower floor's red blood cell is squeezed into the blood bag 3 of right side, due to being equipped with check valve on drainage tube I 4 and drainage tube II, in blood plasma and red blood cell
It will not be flow backwards during extrusion, improve separative efficiency；After the completion of separating for the first time, by middle blood bag 1, left side blood bag 2 and right side
Blood bag 3 is overall to carry out second of centrifugation, centrifuges appropriate increase centrifugal force and centrifugation time, after the completion of centrifugation, middle blood for the second time
Bleeding of the umbilicus in bag 1 is equally divided into three layers, and upper plasma and lower floor's red blood cell are now squeezed into left side blood bag 2 and the right side respectively respectively again
In side blood bag 3, and umbilical cord blood hematopoietic stem cell is then stayed in middle blood bag 1, then by the sampling analysis of probe tube 6, has been separated
Cheng Hou, drainage tube I 4, drainage tube II 5 and probe tube 6 are finally cut into heat seal respectively, while by left side blood bag 2, right side blood bag 3
Heat seal band between middle blood bag 1 is cut off along center line, and left side blood bag 2 and right side blood bag 3 are saved and reserved for other use；It is described
Middle blood bag 1, left side blood bag 2 and the integral installation of right side blood bag 3 be centrifuged in eccentric groove 14 in centrifugal seat 13,
High-elastic sponge liner is provided with eccentric groove 14 so that middle blood bag 1, left side blood bag 2 and the entirety of right side blood bag 3 can be by stabilization clamps
Hold.
Especially, anti-coagulants is preinstalled with the middle blood bag 1 and filter 8, avoids bleeding of the umbilicus when being separated by filtration
Blood clotting.
The course of work of the present utility model：In use, drainage needle 7 is inserted in bleeding of the umbilicus bag, then by pulling piston 11
Piston rod bleeding of the umbilicus is introduced into filter 8 from bleeding of the umbilicus bag, Umbilical Blood Flow enters the right-hand member of piston 11, Ran Houtong after the filtering of filter screen 9
Cross and promote the piston rod of piston 11 that bleeding of the umbilicus is sent into middle blood bag 1, after above-mentioned steps are centrifuged, you can obtain richness
Bleeding of the umbilicus containing stem cell.
The utility model proposes stem cell filter separator efficiently stem cell can be separated from bleeding of the umbilicus, separate
Efficiency high, and making full use of for bleeding of the umbilicus is realized, meanwhile, bleeding of the umbilicus separation process does not contact with the external world, avoids bleeding of the umbilicus contaminated.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
