Abstract
A blood sampler device includes a blood collector and a sampler body. The blood collector is designed to collect a sample of a fluid, such as blood, from a user and to be inserted into the sampler body, such that the collected blood can be discharged into a liquid chamber in the sampler body to mix with a liquid stored in the liquid chamber for testing. The blood collector includes vents that are designed to facilitate the flow of air out of the liquid chamber during this insertion, such that a lower and more consistent pressurization can be achieved within the liquid chamber. This design may also increase user comfort and enhance the accuracy of testing performed on the collected fluid.
