The sample enriching and concentrating analyzing device provided by the utility model adopts the scheme that an objected detectionobject in the body fluid is enriched and concentrated on the surface of the sample enriching and concentrating film to be convenient for the detection object to pass through detection reagent or a detection analyzer to perform next analysis and detection.

Description

Example enrichment concentrates analytical equipment
Technical field
The utility model relates to a kind of example enrichment and concentrates analytical equipment.
Background technology
At present, the analysis to human body fluid (comprising saliva, urine, blood, cerebrospinal fluid etc.) is one of important means of human body health condition or human body diseases.In fact, promptly be effective target contained in the body fluid to be detected thing (comprising albumen, DNA/RNA, cell, compound etc.) reach the whether ill situation of human body health condition or human body for the analysis of human body fluid.But, effective target in the body fluid detects thing, and often content is very low, because the problem of detecting instrument or the sensitivity of detectable card, if directly body fluid is detected often to detect less than effective target and detects thing, or the content error of detected effective target detection thing is very big, causes judged result inaccurate.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, be convenient to that effective target contained in the body fluid is detected thing and carry out the example enrichment that effective enrichment concentrates or detect simultaneously and concentrate analytical equipment.
The technical scheme that the above-mentioned technical matters that solves the utility model adopts is: example enrichment concentrates analytical equipment, comprise the sample divider and the waste collection device that removably connect, sample divider has injection port and is positioned at waste collection device top, be provided with water accepting layer in the described waste collection device, the water accepting layer upper surface is provided with example enrichment and concentrates film, and described example enrichment concentrates the sample export below that film is positioned at the sample divider bottom.
Have sealed sample outlet in the described sample divider or be positioned at the prefiltration layer of sample export top.
Described prefiltration layer is filter paper or the above filter screen of 100 orders.
Described example enrichment concentrates film and is filter paper, nylon membrane, cellulose membrane, glass fibre membrane or contains the earth silicon material film.Or other have the material of pathoklisis to albumen, cell nucleic acid, can adsorb at detecting target.
Described water accepting layer is filter paper, super absorbent resin or super absorbent polymer polymkeric substance.As poly starch etc.
Described sample divider and waste collection device are for being threaded or clamping.Or other are convenient to connected mode that sample divider, waste collection device are separated.
The sample export place of described sample divider bottom is provided with this sample export of control and switches to gauge tap under connection, blocking state.Gauge tap can be devices such as ball valve two logical switches, so that the control example enrichment concentrates the duty of analytical equipment.
Described waste collection device is provided with at least one air hole.This structure can be avoided occurring causing the situation that waste collection device internal gas pressure increases after waste liquid flows into the waste collection device.
The volume of described waste collection device is more than or equal to the volume of sample divider.This setting is a situation of avoiding occurring occurring in the waste collection device waste liquid spill-over.
The example enrichment of this programme concentrates analytical equipment and at first sample solution is joined sample divider through injection port, directly or through the prefiltration layer carry out flowing out from sample export behind the prefiltration, flow through and pass the concentrated film of example enrichment, because concentrating the film below, example enrichment has hydrophilic water accepting layer, the small-molecule substance that comprises water passes example enrichment and concentrates film and adsorbed by water accepting layer, the target detection thing then is trapped example enrichment and concentrates the film surface, target detection thing after enrichment concentrates is convenient to carry out next step analyzing and testing by detectable card or check and analysis instrument, because example enrichment concentrates the sample divider and the waste collection device of analytical equipment and removably connects, therefore concentrate film in the enrichment of needs sample thief and carry out taking apart when next step is analyzed sample divider, take off the concentrated film of example enrichment or directly concentrate on the film with tweezers or other instruments and detect in enrichment; The enrichment that the concentrated analytical equipment of this enrichment can be used for albumen, nucleic acid, cell or other components of body fluid (comprising saliva, urine, blood, cerebrospinal fluid etc.) concentrates, extracts and directly analyzes or indirect analysis.
In sum, the beneficial effects of the utility model are: example enrichment of the present utility model concentrates analytical equipment the target detection thing enrichment in the body fluid is concentrated to the concentrated film surface of example enrichment, so that the target detection thing carries out next step analyzing and testing by detectable card or check and analysis instrument.
Below in conjunction with drawings and Examples example enrichment of the present utility model is concentrated analytical equipment and be further described, but the utility model is not limited to embodiment.
