Abstract
The utility model relates to a new cell separation pipe, belonging to the technical field of medical analysis or medical research equipment. The utility model comprising a separation pipe (1), a small cell filtering screen(2) and a big cell filtering screen(3) is characterized in that: a cavity of the separation pipe (1) is thick in upper and thin in lower, and is cone-shaped. A lower ring-shaped convex (4) and an upper ring-shaped convex (5) are arranged in the internal wall below the separation pipe (1) in turn. The small cell filtering screens (2) and big cell filtering screens (3) are arranged in the upper side of the lower ring-shaped convex (4) and the upper ring-shaped convex (5). The utility model has the advantages of simple structure and reasonable design. Due to the isolation role of the cell filtering screen, the utility model can effectively prevent the disperse of the layered fluid caused by the blood specimen waited for separation, the mixing of the layered fluid and the blood specimen, and the interface of the flood specimen waited for separation and the layered fluid is distinct and the specific gravity have not changed, which not only has good effect of cell separation but also can greatly improve the operating speed of the cell separation, and is time-saving and energy-saving.
Description
Technical field
The utility model belongs to medical analysis or medical research utensil technical scope, specifically a kind of novel cell separator tube.
Background technology
In the prior art, the blood preparation cellular segregation all is to adopt common straight wall separator tube usually, adds earlier parting liquid in separator tube, then with the upper strata that slowly adds layering liquid of the cell suspension extreme care of blood preparation to be separated.Reason owing to separator tube itself, can't place filtering net above the layering liquid, when adding the cell suspension of blood preparation to be separated, although extreme care and slow, but still a minute liquid layer upper strata can be broken up, the cell suspension of blood preparation to be separated occurs mixing with layering liquid, separation surface is unclear, and proportion changes, so that influences the cellular segregation effect, and operating speed is slow, wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned drawback that prior art exists, and a kind of novel cell separator tube is provided.
The purpose of this utility model is achieved in that this novel cell separator tube is to improve to form on the basis of existing separator tube, it comprises separator tube, the little filtering net of cell and cell serious offense filter screen, the separator tube inner chamber is upper coarse and lower fine, be pyramid type, be provided with successively on the separator tube lower inner wall down annular protrusion and on the projection of going in ring, annular protrusion down and on attached respectively little filtering net of cell and the cell serious offense filter screen of joining of protruding upside that go in ring.The diameter of little filtering net of cell and cell serious offense filter screen is corresponding with the upside separator tube internal diameter of following annular protrusion and last belt projection respectively.
When using the utility model, when blood preparation amount to be separated more after a little while, parting liquid can add to the following belt projection of separator tube, places the little filtering net of cell on the projection of going in ring down, adds the cell suspension of blood preparation to be separated again.When blood preparation amount to be separated more for a long time, parting liquid can add to the projection of go up going in ring of separator tube, places cell and be bigger than filter screen on the last projection of going in ring, and adds the cell suspension of blood preparation to be separated again.
Advantage of the present utility model: simple in structure, reasonable in design, because the buffer action of cell filtration net, can prevent effectively that blood preparation to be separated from breaking up laminated fluid level, mix, make blood preparation to be separated and layering liquid interface clear with layering liquid, proportion is constant, not only cellular segregation is effective, but also can improve the operating speed of cellular segregation greatly, and is time saving and energy saving.

Embodiment
Make the utility model with reference to accompanying drawing: this novel cell separator tube is to improve to form on the basis of existing separator tube, it comprises separator tube 1, cell small offence filter screen 2 and cell serious offense filter screen 3, separator tube 1 inner chamber is upper coarse and lower fine, be pyramid type, be provided with successively on separator tube 1 lower inner wall down annular protrusion 4 and on the projection 5 of going in ring, annular protrusion 4 down and on attached respectively little filtering net of cell and the 2 cells serious offense filter screen 3 of joining of protruding 5 upsides that go in ring.The diameter of cell small offence filter screen 2 and cell serious offense filter screen 3 is corresponding with upside separator tube 1 internal diameter of following annular protrusion 4 and last belt protruding 5 respectively.The projection 4 of going in ring down is located at the 2ml place, goes up the projection 5 of going in ring and is located at the 4ml place.
Claims (2)
1, a kind of novel cell separator tube, it comprises separator tube (1), the little filtering net of cell (2) and cell serious offense filter screen (3), it is characterized in that separator tube (1) inner chamber is upper coarse and lower fine, be pyramid type, on separator tube (1) lower inner wall, be provided with annular protrusion (4) and last belt projection (5) down successively, at following annular protrusion (4) and attached respectively little filtering net of cell (2) and the cell serious offense filter screen (3) of joining of last belt projection (5) upside.
2, novel cell separator tube according to claim 1 is characterized in that the diameter of little filtering net of cell (2) and cell serious offense filter screen (3) is corresponding with upside separator tube (1) internal diameter of following annular protrusion (4) and last belt projection (5) respectively.
