Example Embodiment

[0016] Example 1: as attached figure 1 , 2 As shown, the present invention includes a rotating reagent disc 7 , a third chamber 9 arranged on the rotating reagent disc 7 , a third flow channel 1 communicating with the third chamber 9 , and a plurality of liquid transporters communicating with the third flow channel 1 . Structure and the fourth chamber 10 arranged at the end of the third flow channel 1 . The distances between the first chambers 2 of the plurality of liquid transport structures and the rotation axis of the rotary reagent disk 7 are the same. The third chamber 9 , the third flow channel 1 , and the liquid delivery structure are arranged outward in order relative to the rotation axis of the reagent disk. When the rotating reagent disk 7 rotates, the liquid in the third chamber 9 enters the liquid through the third flow channel 1 . In the conveying structure, after all the first chambers 2 of the liquid conveying structure are filled, the remaining liquid enters ...

Example Embodiment

[0020] Example 2: as attached image 3 As shown, on the basis of Embodiment 1, other structures are kept unchanged, and only the position of the variable diameter chamber 4 is changed, so that the variable diameter chamber 4 and the second chamber 5 are connected to form a chamber, and the embodiment can also be realized. 1 effect.

[0021] When the present invention is used, an appropriate amount of liquid is firstly added to the third chamber, and the rotating reagent disk rotates at a speed lower than a certain speed threshold. In this case, the liquid entering the first chamber 2 will not open the capillary passive valve, When the rotational speed is higher than the threshold, the liquid in the first chamber 2 opens the passive capillary valve, and the liquid enters the second chamber 5 . In the case of low rotation speed, the liquid in the third chamber 9 is thrown out into the third flow channel 1, and then transported forward along the third flow channel 1, and then en...

Abstract

The invention relates to a quantitative liquid transfer device. The quantitative liquid transfer device comprises a rotating reagent tray, a third chamber, a third flow channel, a plurality of liquidconveying structures and a fourth chamber, wherein the liquid conveying structures comprise first chambers, second chambers and diameter varying chambers, and the inner diameters of the diameter varying chambers are greater than that of a first flow channel to form capillary tube passive valves; when the rotating reagent tray rotates, liquid located in the third chamber flows out through the thirdflow channel under the action of the centrifugal force, then the first chambers of the liquid conveying structures are filled with the liquid in sequence, the excess liquid enters the fourth chamber;when the rotation speed of the rotating reagent tray is controlled to be lower, due to the action of the capillary tube passive valve, the liquid stays in the first chambers and cannot enter the second chambers, when the rotation speed is increased, the centrifugal force in the first chambers is increased, the liquid breaks through the limitation of the capillary tube passive valves and enters the second chambers; by adjusting the sizes of the first chambers, it can be achieved that the liquid is taken out quantitatively and conveyed into the second chambers, and quantitative conveying of theliquid is achieved.

Description

technical field [0001] The invention relates to a liquid quantitative transfer device. Background technique [0002] When performing sample testing in the life sciences and medical fields, it is necessary to mix the sample with a variety of different reagents, or perform a mixed test with a specific reagent in different proportions to achieve sufficient detection of the sample. Quantitative collection of samples is often required. At present, when the liquid is divided into multiple equal portions, or the liquid is quantitatively divided into different volumes, a separate operation is required, and the function of quantitatively dividing the liquid into multiple portions cannot be realized at one time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liquid quantitative transfer device that can quantitatively divide liquid into multiple portions at one time. [0004] The technical scheme adopted in the present...
