Description

DEVICE AND KIT FOR BODY FLUID SAMPLING

The present invention relates to a bodily fluid collection device and a body fluid collection kit comprising the same, and to a bodily fluid collection device capable of absorbing and drying a body fluid for bioanalysis and the like, and a body fluid collection kit comprising the same.

In order to perform endogenous and exogenous metabolite analysis, protein analysis and chemical substances present in human or animal body fluids, a device for absorbing and storing a predetermined volume of human or animal body fluids, such as urine, tears, saliva, and blood, is required. do.

Conventional bodily fluid collection devices have only a container function for collecting and storing body fluids from humans and animals, and cold chains of refrigeration and freezing processes to prevent denaturation in moving them to a place for performing endogenous and exogenous metabolites and protein analysis There is a problem with the distribution method. However, if bodily fluids are dried immediately after collection, endogenous and exogenous metabolites and proteins can be analyzed while stably maintained, and distribution problems such as cold chain are significantly reduced.

On the other hand, in the case of using a needle for collecting human or animal blood, conventionally, a bodily fluid such as blood is collected using a syringe or a needle-type blood sampler. In this way, after blood was bled through a blood purifier, a separate blood collection device had to be used. Accordingly, since the blood collection operation is complicated and it is difficult to collect blood immediately after blood collection, unsanitary problems such as contamination of the blood sampling site or the collection tool may occur in the meantime.
