Description

Technical Field

[0001] The present invention relates to the technical field of medical testing, in particular to a liquid adding and diluting device used in a medical testing department. Background Art

[0002] Medical testing is a science that conducts microbiological, immunological, biochemical, genetic, hematological, biophysical, and cytological tests on materials taken from the human body to provide information for the prevention, diagnosis, and treatment of human diseases and the assessment of human health. Generally, in routine, physiological, and biochemical testing operations in medical testing, it is often necessary to dilute the sample before processing and testing. Diluent (buffer) is one of the most commonly used reagents in medical testing. It can be used in automatic blood analyzers, immune-specific protein analyzers, etc. Dilution refers to the process of reducing the solute concentration in a solution by adding a solvent. Dilution is a method of mixing drugs or other substances with solvents to reduce their concentration. This process helps control the release rate of drugs or reduce the risk of toxicity. For example, patients with heart disease may experience symptoms such as difficulty breathing due to decreased heart function. After dilution, the heart burden is reduced, and the above-mentioned discomfort symptoms are alleviated.

[0003] During medical testing, some solution reagents require a dilution device to balance the concentration of the solution. Dilution is usually done by manual mixing or machine mixing. The ratio of dilution is not accurate, and it is not convenient to clean the dilution device after dilution, which can easily leave residual components that affect the next test.
