Abstract
The utility model discloses a bone marrow collecting filter, a main body of which is a hollow tube, the both ends of the hollow tube are provided with a filter inlet and an outlet, three layers of filter meshes with the different diameters of the mesh holes are arranged in the hollow tube, and the diameters of the mesh holes of the three layers of filter meshes are decreased sequentially from left to right. The structure can complete the filtration of the collected bone marrow in the closed filter at one time and the efficiency is high, so the utility model can avoid the defect of easy pollution of the open operation of the traditional filtration methods, has convenient operation and saves the materials at the same time.
Description
(1) technical field
This utility model belongs to medical apparatus, relates generally to a kind of bone marrow collection filter.
(2) background technology
It is an important ring of bone marrow transplantation that bone marrow collection filters, and is mainly used in the embolus of removing in the graft, thus the histoorgan thromboembolism that reduces or avoid the embolus (as fat drop, blood clotting point etc.) in the graft to cause.Filtering quality can directly have influence on the work of planting of hematopoietic stem cell.Traditional filter method is that No. 9 and twice filtration of No. 12 syringe needles are finished, troublesome poeration, and operating process is open easily pollutes bone marrow, and has wasted material.
(3) summary of the invention
The purpose of this utility model provides a kind of bone marrow collection filter, and it can make bone marrow filter and finishes airtight next time, and efficient is high and reduced pollution.
Described bone marrow collection filter body is a hollow pipe, and its two ends are provided with an entrance and exit, is provided with the three layer filtration net that mesh diameter varies in size in the hollow pipe, and the three layer filtration net mesh diameter that exports from entering the mouth to reduces successively.
Above-described bone marrow collection filter is owing to be provided with three metafiltration nets in airtight hollow pipe, diameter is descending, and it can make bone marrow export from entering the mouth to and once finish filtration, efficient height in airtight pipe, avoided the open defective of easily polluting of traditional filtering method operation, easy to operate.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.Shown in the figure: 1-filter inlet, 2-filter hollow pipe main body, 3,4, the 5-drainage screen, 6-filter outlet.
(5) specific embodiment
As shown in Figure 1, main body of the present utility model is a hollow pipe 2, its two ends are provided with filter inlet 1 and outlet 6, in hollow pipe 2, be provided with the different drainage screen of three-layer network pore diameter size 3,4,5, the mesh diameter of three layer filtration net from left to right reduces successively, and drainage screen 3,4,5 mesh diameters are followed successively by 196 microns, 166 microns, 132 microns.During use, filter inlet 1 connects syringe adapter, and filter outlet 6 connects syringe needle, and the bone marrow of collection 1 enters the hollow pipe 2 from entering the mouth, and is filled into outlet 6 through three layers of different drainage screen of diameter.Filtering bone marrow is once finished in airtight hollow pipe, and is easy to operate, reduced pollution simultaneously, saved material.
Claims (1)
1, a kind of bone marrow collection filter, be primarily characterized in that: its main body is a hollow pipe (2), the two ends of hollow pipe (2) are provided with filter inlet (1) and outlet (6), be provided with the different drainage screen of three-layer network bore dia (3), (4), (5) in hollow pipe (2), the mesh diameter of three layer filtration net from left to right reduces successively.
