Abstract
The utility model discloses a liquid sample injector. The liquid sample injector comprises a plate body, wherein detection micro-pores are evenly distributed on the plate body, a cavity is arranged in the middle of the plate body which is driven by an electric motor for rotation, detection micro-pores which are independent of one another are evenly distributed around the cavity, sample flow channels are arranged from the side wall of the cavity to all detection micro-pores respectively, an annular filtering screen is arranged inside the cavity, and a semi-closed space is formed inside the plate body through an upper cover with an opening in the middle, which is fastened above the plate body. The liquid sample injector has the advantages that a centrifugal device in a simple structure is used for quickly distributing and injecting liquid samples, and the liquid sample injector is applicable to detection of various clinical samples. Samples are added into the cavity, then the plate body is rotated, before the rotating speed reaches a certain critical value, liquid samples are distributed on the inclined side wall of the cavity under the effect of centrifugal force, after the rotating speed reaches the critical value, liquid samples flow into all detection micro-pores uniformly through all sample flow channels, and bulk matters or sediments in samples are filtered by the annular filtering screen, so that the quick distribution and sample injection can be achieved.
Description
Technical field
The distribution application of sample of biological sample when the utility model relates to biochemical test especially relates to the higher liquid sample sample injector of a kind of efficient.
Background technology
In biochemical test or medical test, often use polytype microwell plate or check-out console, purpose is liquid chemical reagent or biological sample to be assigned in a plurality of independently reacting holes react, deposit or observe, and the at present comparatively general quadrat method that adds is to adopt sample loading gun manual or automatically sample or reagent are distributed application of sample.Because clinical common microbiological Test sample has blood, cerebrospinal fluid, urine, fester, pleura water, ight soil, sputum and Genitourinary secretion etc. usually, just can carry out application of sample after wherein need to doing pre-service than sample thickness and that contain sediment, and pre-treatment step comparatively bothers usually, so there is larger limitation in the current sample loading mode that adds: manual mode relatively flexibly but waste time and energy, though adopt autopipette can improve application of sample efficient, equipment is comparatively complicated and limited by the sample form.
Summary of the invention
The purpose of this utility model is to provide a kind of suitable polytype sample and the simple and rapid liquid sample sample injector of distribution method.
For achieving the above object, the utility model can be taked following technical proposals:
Liquid sample sample injector described in the utility model, comprise and be distributed with the plate body that detects micropore, plate body middle part by the motor-driven rotation offers cavity, and separate detection micropore distributes around described cavity, detects micropore from described cavity side walls and offers respectively the sample runner to each; Being pressed together on the plate body upper center makes the detection micropore in the plate body form good sealing with the loam cake of opening.
The inflow point of described sample runner is horn opening.
The sidewall of described cavity is the inclined-plane.
Described plate body is dish type, annular, dish or sector structure.
In described cavity, be placed with annular filter screen.
The utility model has the advantage of the fast allocation application of sample that adopts centrifugation apparatus simple in structure to realize liquid sample, be applicable to the detection of various clinical sample.Sample is added in the cavity, then rotate plate body, before rotating speed reaches certain dividing value, because the effect of centrifugal force, liquid sample can be distributed on the sloped sidewall of cavity, and after rotating speed reached dividing value, liquid sample can entering each and detect in micropore by each sample uniform flow passage, bulk in the sample or sediment thing are filtered out by annular filter screen, realize the fast allocation application of sample.

Embodiment
The utility model is the fast allocation application of sample of realizing a plurality of detection micropores of reagent or sample by centrifugal method.
As shown in Figure 1, 2, 3, liquid sample sample injector described in the utility model comprises being evenly equipped with the plate body 2 that detects micropore 1, and plate body 2 is driven rotation by slowspeed machine, realizes centrifugal application of sample.Offer cavity 3 at plate body 2 middle parts, separate detection micropore 1(detects the size and number of micropore and can adjust) evenly distribute around cavity 3, detect micropore 1 from cavity 3 sidewalls to each and offer respectively sample runner 4; Withholding or stick on plate body 2 upper center makes the detection micropore 1 in the plate body form good sealing with the loam cake 6 of opening 5.Flow to for ease of sample and to detect in the micropore 1, the inflow point of sample runner 4 is designed to horn opening; The sidewall of cavity 3 is the inclined-plane, is beneficial to flowing down of unnecessary sample behind sample sample introduction and the sample introduction.During actual the use, plate body 2 can manufacture dish type, annular, dish or sector structure.When containing bulk or sediment in the sample to be allocated, can block and residue in the sample be kept off in cavity 3 by filter screen 7 at cavity 3 interior placement annular filter screens 7, realize that various samples all can the fast allocation sample introduction.
During use, pour into reagent or sample in the cavity 3 of plate body 2 from the opening 5 at loam cake 6 middle parts, then plate body 2 is fixing, carry out of short duration centrifugal rotation by driven by motor, under certain speed, reagent or sample are distributed on the sidewall of cavity 3 after annular filter screen 7 filters, motor continues to accelerate, reagent or sample will enter each and detect in the micropore 1, and remaining block sample or residue are then kept off in cavity 3 by filter screen 7 simultaneously, thereby realize not being subjected to the fast allocation sample introduction of sample restriction.
