Biochemical detection equipment

Abstract

The invention discloses biochemical detection equipment and belongs to the technical field of rapid diagnosis. The biochemical detection equipment comprises a substrate, and a liquid channel, a calibration channel, a gas channel and a test paper that are provided on the substrate, wherein the liquid channel comprises a liquid inlet channel and a reaction channel which are in communication with each other; the calibration channel is in communication with the reaction channel, and a calibration reagent can flow into the reaction channel through the calibration channel; the gas channel is in communication with the liquid inlet channel, and the gas can drive the liquid in the liquid inlet channel to flow to the reaction channel through the gas channel; and the reaction electrode on the test paper extends into the reaction channel. The invention provides the gas channel and the liquid channel which are connected with each other, so that the sample can conveniently flow from the liquid inletchannel to the reaction channel under the action of gas. The sample flow is driven by the pneumatic method, which is simple and convenient in operation, simplifies manufacturing process of the biochemical detection equipment at the same time, and reduces costs.

Description

technical field [0001] The invention relates to the technical field of rapid diagnosis, in particular to a biochemical detection device. Background technique [0002] Point-of-care testing (POCT) refers to the clinical testing performed next to the patient, which can be analyzed immediately at the sampling site, eliminating the need for complex processing procedures during laboratory testing of specimens, so as to quickly obtain test results A new class of methods. POCT products have become an important branch and one of the fastest growing fields in the in vitro diagnostic products (IDV) industry. POCT products started relatively late in the Chinese market, and the current market size is small. However, with the development of public health in my country, rapid inspections of hospital operating rooms / emergency / intensive care units, or the construction of medical institutions in remote areas, etc. , POCT is playing a huge market potential and application space.

Problems solved by technology

However, in the existing POCT products, most of the samples use the siphon effect to complete the flow. The siphon effect has high requirements on the length and cross-sectional size of the liquid channel, the manufacturing process is complicated, and the user-side operation is also troublesome; in addition, traditional POCT products are also difficult to achieve. Collect a sample and measure multiple biological and chemical indicators at the same time
