Description
Technical field
The present invention relates to technical field of in vitro diagnostic reagents, specially a kind of backflow preventing structure in reagent disc channel.
Background technology
External diagnosis reagent and instrument are collectively referred to as in-vitro diagnosis medical instrument in foreign countries.Belong to one of medical instrument
Point.In China, external diagnosis reagent refers to：It can be used alone or used with instrument, utensil, equipment or system in combination, in disease
Prevention, diagnosis, Treatment monitoring, Observation On The Prognosis, during health status evaluation and the prediction of genetic disease, for people
Body sample (various body fluid, cell and tissue samples etc.) carries out reagent, kit, calibration object object and the quality-control product object of vitro detection
Deng.
External diagnosis reagent, which needs to be placed into, carries out multinomial detection on reagent disc, existing reagent disc structure design does not conform to
It manages, the liquid-conveying ducts traffic organising on reagent disc is inconvenient, and is easy to happen refluence, causes reagent that may occur reversely to mix,
Influence checkout and diagnosis.
Invention content
It is an object of the invention to overcome prior art defect, it is logical to provide a kind of design optimization, easily manufactured reagent disc
The backflow preventing structure in road.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A kind of backflow preventing structure in reagent disc channel, including inlet tube, outlet tube and be connected between inlet tube and outlet tube
Curved valve.
The inlet tube, outlet tube and curved valve are coplanar and be respectively positioned on reagent disc.
As a further improvement on the present invention, the outer end of the inlet tube is more than outlet tube at a distance from the center of circle of reagent disc
At a distance from the junction and the center of circle of curved valve；
As a further improvement on the present invention, the curved valve is bent to circle centre position.
As a further improvement on the present invention, the caliber of the inlet tube is more than the caliber of outlet tube.
Compared with prior art, obtained by the present invention to have the beneficial effect that：
It is simple and reasonable the present invention be directed to the reagent passage backflow preventing structure that reagent disc optimizes, it is easy to make,
Production cost is low, the phenomenon that easily capable of preventing reagent from being flow backwards in channel, and reagent is avoided reversely to mix, and diagnosis is caused to detect
Error occurs, improves the accuracy of in-vitro diagnosis.
Description of the drawings
The accompanying drawings which form a part of this application are used to provide further understanding of the present invention, and of the invention shows
Meaning property embodiment and its explanation are not constituted improper limitations of the present invention for explaining the present invention.
Accompanying drawing 1 is the structural representation of the present invention；
Attached drawing 2 is position view of the present invention on reagent disc.
In the accompanying drawings：
20 inlet tubes, 21 outer ends, 30 outlet tubes, 31 junctions, 4 curved valves, 5 reagent discs, 6 centers of circle.
Specific implementation mode
Below in conjunction with attached drawing to this practical further details of narration of progress.
As shown in attached drawing 1-2, a kind of backflow preventing structure in reagent disc channel, including inlet tube 20, outlet tube 30 and connection
Curved valve 4 between inlet tube 20 and outlet tube 30.The inlet tube 20, outlet tube 30 and curved valve 4 are coplanar and be respectively positioned on reagent
On disk 5.The outer end 21 of the inlet tube 20 is more than the junction 31 of outlet tube 30 and curved valve 4 at a distance from the center of circle of reagent disc 56
At a distance from the center of circle 6；The curved valve 4 is bent at the center of circle 6.The caliber of the inlet tube 20 is more than the caliber of outlet tube 30, into
Hydraulic coupling is big, is convenient for feed liquor.
When reagent disc 5 rotates in the forward direction, reagent is by the hydraulic coupling of centrifugal force and reagent itself, reagent sheet in outlet tube 30
When the hydraulic coupling of body is more than the centrifugal force that it is subject to, reagent is entered from outlet tube 30 in curved valve 4, due to the knee of curved valve 4
The distance in the opposite center of circle 6 is less than distance of the outlet tube 30 with respect to the center of circle 6, therefore the reagent in curved valve 4 is entered out by centrifugal force
Liquid pipe 30；When reagent goes out liquid and finishes, curved valve 4 and inlet tube 20 are blank pipe, when reagent disc 5 reversely rotates at this time, at curved valve 4 by
The centrifugal force arrived is less than the centrifugal force of junction 31, therefore the reagent in outlet tube 30 can not flow back into curved valve 4.The inlet tube
When reagent disc 5 rotates in the forward direction feed liquor, the centrifugal force at outer end 1 is more than the centrifugal force of reagent in outlet tube 30 for 20 outer end 21,
Into complete reagent, when inlet tube 20 is empty, the reagent at outer end 1 forms the fluid-tight that fluid-tight blocks inlet tube 20 to be communicated with curved valve 4,
The air that can be obstructed in inlet tube 20 enters curved valve 4.
It is simple and reasonable the present invention be directed to the reagent passage backflow preventing structure that reagent disc optimizes, it makes
Convenient, production cost is low, the phenomenon that easily capable of preventing reagent from being flow backwards in channel, avoids reagent from reversely mixing, causes to examine
Error occurs for disconnected detection, improves the accuracy of in-vitro diagnosis.
Embodiment described above is merely a preferred embodiment of the present invention, and the simultaneously exhaustion of the feasible implementation of non-present invention.Institute
Term be explanation and term exemplary, and not restrictive, due to the present invention can be embodied in a variety of forms without
It is detached from the spirit or essence of invention, it should therefore be appreciated that above-described embodiment is not limited to any details above-mentioned, and should be weighed in accompanying
It is widely explained in spirit and scope defined by profit requirement, therefore falls into whole variations in claim or its equivalent scope
Appended claims are all should be with remodeling to be covered.
