Abstract
The invention relates to a liquid time delay structure, which comprises a plurality of U-shaped pipelines arranged between a liquid starting position and a liquid target position, wherein two adjacent U-shaped pipelines are communicated through an accelerating pipeline which is arranged along the radial direction of the rotation center of a reagent disk; the invention increases the total path through which the liquid needs to flow when transferring to increase the time required for transferring the liquid between the two positions by providing a continuous U-shaped pipeline between the two positions.
Description
Technical Field
The invention relates to a liquid time delay structure.
Background
The reagent disk is regarded as a development trend of modern medical treatment, and is more and more taken into consideration by more enterprises. The reagent tray can divide the added liquid sample into a plurality of parts, and can realize a plurality of functions such as sample quantification and the like by utilizing a specific pipeline structure.
In the practical use process, the reaction time of the liquid in each reaction tank is different sometimes due to the requirements of reaction conditions or other factors, and the reagent tray can stop rotating only after the last reaction is finished, so that the liquid in some reaction tanks or pipelines is required to delay flowing.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a liquid time delay structure, which can prolong the time required by transferring liquid between two positions.
The technical scheme adopted by the invention is as follows:
a liquid time delay structure comprises a plurality of U-shaped pipelines arranged between a liquid starting position and a liquid target position, wherein two adjacent U-shaped pipelines are communicated through an accelerating pipeline, and the accelerating pipeline is radially arranged along the rotation center of a reagent disk.
Further, the liquid target location is radially outward relative to the liquid start location.
Furthermore, a plurality of U-shaped pipelines are arranged outwards along the radial direction of the rotation center of the reagent disk.
Furthermore, two side pipes of the U-shaped pipeline are in a circular arc shape concentric with the rotation center of the reagent disk.
The invention has the positive effects that: the invention increases the total path through which the liquid needs to flow when transferring to increase the time required for transferring the liquid between the two positions by providing a continuous U-shaped pipeline between the two positions.

FIG. 1 is a schematic view of the structure of the present invention.
Detailed Description
As shown in the attached figure 1, the liquid transfer device is used for transferring liquid between two positions in a pipeline on a rotating reagent disk, and comprises a plurality of continuous U-shaped pipelines 3 arranged between a liquid starting position 1 and a liquid target position 2, two adjacent U-shaped pipelines 3 are communicated through an accelerating pipeline 4, the accelerating pipeline 4 is arranged along the radial direction of the rotation center of the reagent disk, and when the liquid flows into the accelerating pipeline 4, the liquid is accelerated and then enters the U-shaped pipelines 3. In the flow direction of the liquid, the U-shaped pipe 3 at the foremost position communicates with the liquid start position 1, and the U-shaped pipe 3 at the endmost position communicates with the liquid target position 2.
The liquid target position 2 is radially outward relative to the liquid starting position 1, in this embodiment, the liquid starting position 1 and the liquid target position 2 are both located at a certain position on the pipeline, and it is known to those skilled in the art that the liquid starting position 1 and the liquid target position 2 may also be a liquid storage bin or a reaction bin, etc. The invention mainly considers the problem of the transfer time of the liquid before two points, and the functions of the starting point and the end point of the liquid are not limited.
The plurality of U-shaped pipelines 3 are sequentially and outwards arranged along the rotation center of the reagent disk in the radial direction, and two side pipes of the U-shaped pipelines 3 are in a circular arc shape concentric with the rotation center of the reagent disk.
According to centrifugal force, when liquid enters into the side pipe of U-shaped pipeline 3, can flow at the uniform velocity, only can accelerate when liquid outwards moves, liquid is full of every section pipeline gradually, flows to the outside gradually, plays the effect of buffering, has effectively prolonged the required time of liquid transfer.
It should be noted that the inside and outside mentioned in the present invention are based on the rotation center of the reagent disk, and the side close to the rotation center is the inside and the side far from the rotation center is the outside. In the present invention, the center of rotation of the reagent disk is located at a position below the pipe as shown in FIG. 1.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
