Embodiment Construction

[0043] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0044] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected" or "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0045] Unless otherwise defined, all technical and scientific terms used herein have t...

Abstract

The invention relates to a microfluidic chip and an in-vitro detection device comprising the microfluidic chip. The microfluidic chip is provided with a sample adding cavity, a first microfluidic channel, a precipitation cavity, a second microfluidic channel, a first capillary flow channel, a third microfluidic channel and a quantitative detection cavity. The sample adding cavity, the precipitation cavity and the quantitative detection cavity are formed in the microfluidic chip, a to-be-detected sample can be added into the sample adding cavity through a sample adding hole, solid precipitate and liquid can be separated through centrifugal separation to obtain a to-be-detected sample solution containing a target substance, to-be-detected sample solutions in the sample adding cavity, the first microfluidic channel and the second microfluidic channel can be driven by a capillary force of the first capillary flow channel to flow, the liquid finally forms siphoning action and external centrifugal action to flow into the quantitative detection cavity to quantify the to-be-detected sample solution. The microfluidic chi has a relatively simple structure, is easy to manufacture and form andcan be widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnosis, in particular to a microfluidic chip and an in vitro detection device comprising the microfluidic chip. Background technique [0002] In Vitro Diagnosis (In Vitro Diagnosis, IVD) refers to the technology of taking samples (blood, body fluid, tissue, etc.) from the human body for detection and analysis to diagnose diseases. The detection process requires corresponding instruments and reagents, and these instruments and reagents An in vitro diagnostic system is formed. In vitro diagnostic systems are roughly divided into two types: one is represented by the testing center laboratory, which has the characteristics of system modularization and automation, and performs pipeline inspection on samples, so it also has high throughput, high efficiency, and high sensitivity. However, the entire system also has defects such as high cost, large volume, and the need for professional operation. It ...
