Application of dry biochemical analyzer in clinical diagnosis

　　Pharmaceutical Network Technical Article: Biochemical analysis is one of the most commonly used means of clinical diagnosis, according to whether the chemical reaction between the sample and the reagent is a solid phase chemical reaction, biochemical analysis can be divided into wet chemistry (ordinary) and dry chemical biochemical analysis With the increasing requirements of clinical reporting time on the results of emergency biochemical testing and the rapid development of clinical biochemical testing technology, emergency biochemical testing technology has gradually developed from traditional wet chemistry to dry biochemical
Wet chemistry, a common chemical reaction, is a chemical reaction that occurs when liquid reagents and samples are added to the reaction container
Dry chemistry, the use of multi-layer film solid phase reagent technology, as long as the liquid sample directly added to the reagent carrier has been cured in a special structure, that is, dry reagent, to the water in the sample as a solvent, will cure the reagent sluice on the carrier, and then with the sample of the components to be tested for chemical reaction, so as to analyze and determine
Fully automatic dry biochemical analyzer, because of its fast test, simple operation, accurate results, can be used for biochemical testing in various occasions, widely used in small hospitals, large and medium-sized hospital son and emergency, medical examination centers, communities, rural and other primary health care institutions
Chengdu, a company's fully automatic dry biochemical analyzer, in this outbreak in Wuhan, has been listed on the China Medical Equipment Association recommended the new crown pneumonia urgently needed medical equipment catalog It has the advantages of intelligent and portable, simple operation, high degree of automation, small sample size, accurate test, maintenance-free and so on, can get test results in 12 minutes, eliminate cross-contamination, efficient lying in isolated areas and diagnosis of emergency cases
Freeze-dried reagents in dry biochemical analyzers are valid for up to one year Save temperature is 2-8 degrees Celsius for easy storage and transportation
The volume of the freeze-dried beads is generally between 1-100 ?l At this stage, one of the major technical difficulties for the production of freeze-dried beads lies in the point liquid: 1, micro-point liquid: the common point liquid volume from 1 micro to 100 microliters Common pumps, which are commonly known to people, are difficult to stabilize the liquid in such a small range and ensure consistency
2, high precision point liquid: freeze-dried bead ball to point liquid accuracy and shape requirements are high Laboratory operations are often difficult to control in terms of accuracy and consistency due to manual consistency issues and the simplicity of equipment If the use of ordinary pumps, in the micro-point liquid, the controllability and precision of the pump is not good, it is very easy to cause the shape of the ball different size, the shape of the ball is not good, or the small ball fell on the surface of liquid nitrogen when the explosion into a number of microspheres When the amount of liquid is small, it cannot be formed into a ball of consistent shape, and when the amount is large, it is easy to separate into multiple small balls If the final product freeze-dried beads of the ball shape is not consistent, the size is not the same, will affect the subsequent distribution to the reagent disk / card, testing process and test results
In order to solve the above-mentioned microfluidic high-precision point liquid problem, Guangzhou Feisheng Precision Equipment Co., Ltd technical team since 2010 began to focus on the development of micro(micro-upgrade and na upgrade) fluid control system, focusing on micro-upgrade and nano upgrade other micro-point liquid, based on the leading microfluidic pump technology, the introduction of DS228 desktop liquid nitrogen-dried jelly bead system, the minimum amount of liquid can be up to 1 microliter   DS228 liquid nitrogen freeze-dried bead system DS228 system with trace (1 microliter), high accuracy (0.5%), high efficiency, high ball consistency, and automated continuous production of technical advantages, is the biochemical pharmaceutical company freeze-dried ball ball should choose the system
