Abstract

The utility model provides a cell filter special for a flow cytometer and belongs to the technical field of medical equipment. The cell filter special for the flow cytometer is formed by connecting ten filters. Each filter comprises a frame (1), a filter sieve (2) and a break-off point (3) between every two adjacent filters. Each filter sieve (2) is installed at the bottom of the corresponding frame (1), and each break-off point (3) is installed between every two corresponding adjacent filters. The filters are separated and used independently or used simultaneously. The filter sieves (2) are made of nylon net of 20 microns to 150 microns. A break-off point (3) is arranged between every two adjacent filters so that the filters can be used simultaneously or be separated and used independently. The cell filter special for the flow cytometer is simple in structure and low in production cost, the design thought is completely based on practicability and operability of experiments, and the cell filter special for the flow cytometer is quite suitable for sample pretreatment before testing of the flow cytometer, especially for large-batch sample treatment.

Description

The special-purpose cell filter of a kind of flow cytometer

Technical field

The utility model relates to the special-purpose cell filter of a kind of flow cytometer, is applicable to the pre-service that flow cytometer detects front sample, belongs to medical apparatus technical field.

Background technology

Flow cytometer is a kind of hygiene medical treatment apparatus, is mainly used in the cell in cell suspension or organelle to carry out Quick Measurement, and in cell biology, immunology, oncology, hematology, science of heredity, pathology, there is purposes very widely in the fields such as clinical examination.Flow cytometer belongs to high-end, accurate, expensive instrument, so require also higher to the pre-service of sample.Before loading, be that the histocyte of cultured cell or processing all will be prepared into cell suspension, with screen pack, filter, in order to avoid agglomerating cell or impurity are blocked instrument.

Be not specifically designed in the market the cell filter of flow cytometer, get a nylon wire plug filters temporarily on detector tube, after filtrator filtration by other model, again cell is transferred in flow cytometer dedicated test pipe, wasted time and energy, affected work efficiency.The special-purpose cell filter of flow cytometer of our design can directly be enclosed within on the detector tube of flow cytometer, and 10 filtrators link together, and can combine use and can use separately again, facilitates large batch of sample preparation.

summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cell filter that is exclusively used in flow cytometer sample pretreatment is provided, not only can used aloned, can also 10 be used in conjunction.

For achieving the above object, the technical solution of the utility model: the special-purpose cell filter of a kind of flow cytometer, to be formed by connecting by 10 filtrators, each filtrator has comprised the snap point 3 between framework 1, sieves 2 and adjacent filter, sieves 2 is contained in the bottom of framework 1, and snap point 3 is contained between adjacent filtrator; Each filtrator separately uses separately, or uses simultaneously;

Sieves 2 adopts the nylon wire of 20 μ m～150 μ m.

Described filter frame 1 adopts polypropylene material.

Further, 10 special-purpose cell filters are linked together, facilitate large batch of sample preparation.

Further, between every two cell filters, design a snap point, after fractureing, each cell filter is used separately, facilitates the processing of a small amount of sample.

The beneficial effects of the utility model:

(1) be applicable to very much the pre-service that flow cytometer detects front sample, particularly facilitate large batch of sample preparation.

(2) the utility model, simple in structure, low cost, mentality of designing is the practicality in order to test completely, operability.

(3) not only can used aloned, can also be placed on test tube rack and use simultaneously.

Accompanying drawing explanation

The special-purpose cell filter of Fig. 1 the utility model flow cytometer, 1, framework, 2, sieves, 3, snap point.

The special-purpose cell filter of Fig. 2 the utility model flow cytometer is used schematic diagram, a, flow cytometer detector tube, b, standard test tube rack, c, cell filter.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.

A kind of cell filter that is exclusively used in flow cytometer of the present embodiment, as shown in Figure 1, comprising: 10 cell filters that link together.Each filtrator comprises polypropylene frame 1, nylon net filter sieve 2, snap point 3.

The present embodiment as shown in Figure 2, it is upper that flow cytometer detector tube a can be placed directly in standard test tube rack b, and cell filter c installs in detector tube successively, is convenient to carry out the pre-service of flow cytometer sample, is particularly suitable for large batch of sample preparation.

This cell filter of the present utility model can also be taken independent use apart, facilitates the pre-service of single sample.
