Technical Field

The utility model relates to a creatinine detects the field, and more specifically says that it is a blood sampler for creatinine detects.

Background

Creatinine (CRE) is a product of human muscle metabolism, including both exogenous and endogenous. Exogenous creatinine is a product of meat metabolism in vivo; endogenous creatinine is a product of in vivo muscle tissue metabolism. Under normal conditions, the creatinine content in the human body is substantially stable. If the volume of the body muscle is not changed obviously, the generation amount of the endogenous creatinine is relatively constant and is mainly discharged out of the body through glomerular filtration. Therefore, under the condition that exogenous creatinine is stable, the concentration of creatinine in blood can be used as one of the indexes for detecting the glomerular filtration function, but when a patient is infected by virus and the concentration of creatinine in the body changes, for example, when the patient is infected by HIV, a fusion reaction is performed between a blood sample to be detected and different reagents in the creatinine detection process, but a disposable collecting device is adopted in the blood sample collection process, and an operator is likely to be polluted in the collecting process, so that a blood sampler for detecting creatinine is provided to solve the problems.
