Abstract
The utility model discloses an examination filter and belongs to the field of medical examination machinery. The examination filter comprises a hopper, and is characterized in that a primary step is arranged at the inner upper end of the hopper, a secondary step corresponding to the primary step is arranged at the inner lower end of the hopper, a primary filter film is arranged on the primary step, a secondary filter film is arranged on the secondary step, the number of meshes of the secondary filter film is larger than that of meshes of the primary filter film. Compared with the prior art, the examination filter has the advantages that operating is convenient, impurities are effectively filtered, examination result accuracy is improved, and work efficiency of the medical staff is improved and the like.
Description
Technical field
The utility model relates to a kind of medical inspection apparatus, especially a kind of check filter, characteristics such as that this filter has is easy to operate, good filtration effect, raising assay accuracy.
Background technology
At present, hospital inspection section office are when filtering patient's inspection specimen or other reagent, be to adopt funnel to add the mode that filter paper matches mostly, this mode troublesome poeration, if filter paper is not completed, be easy to make the impurity in reagent or the sample to sneak in the filtered fluid of lower floor, influence the accuracy of assay.
The utility model content
Technical assignment of the present utility model is to provide a kind of check filter at above-mentioned deficiency of the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: the check filter, comprise funnel, it is characterized in that the position, upper end is provided with the one-level ladder in described funnel, lower end part and one-level ladder corresponding position are provided with the secondary ladder in described funnel, be provided with the one-level filter membrane at described one-level ladder, be provided with the secondary filter membrane at described secondary ladder, the order number of described secondary filter membrane is greater than one-level filter membrane order number.
The beneficial effect that the utlity model has is:
1, the accuracy of easy to operate, good filtration effect, raising assay.
2, alleviate the medical worker work difficulty, increase work efficiency.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
With reference to Figure of description the utility model is done following detailed description the in detail:
As shown in the figure, the utility model comprises funnel 1, wherein, position by the upper end in funnel 1 is provided with one-level ladder 2, on the lower position and the one-level ladder 2 corresponding secondary ladders 3 that are provided with in funnel 1, at one-level ladder 2 one-level filter membrane 4 is arranged fixedly, at secondary ladder 3 secondary filter membrane 5 is arranged fixedly, the order number of secondary filter membrane 5 is greater than the order number of one-level filter membrane 4.
When inspection specimen or reagent are filtered, the funnel lower end is placed the filtrate holder, then sample to be filtered is slowly poured in the funnel 1 by the top of funnel 1, make sample to be filtered pass through one-level filter membrane 4 and secondary filter membrane 5 successively, flow at last in the filtrate apparatus for placing and get final product, because the order number of one-level filter membrane 4 and secondary filter membrane 5 is different, can effectively the magazine in the sample be filtered out successively, guaranteed the accuracy of assay, after finishing using, with funnel 1 irrigation and disinfection, in order to using next time.
