  • Patent number: 11103169
    Abstract: A blood sampler device includes a sampler body forming a hollow internal chamber with upper and lower openings, the sampler body including a sealing device disposed adjacent to the upper opening. The blood sampler device further includes a blood collector adapted to be inserted into the sampler body, the blood collector including a plurality of capillary channels.
    Type: Grant

  • Patent number: 10688486
    Abstract: A pinch wall and dam system for controlling fluid flow movement between a sample receiving pad and a test strip includes a sample receiving pad and a test strip in contact with the sample receiving pad. The fluid seeps more quickly under the first portion of the pinch wall than under the second portion of the pinch wall, such that the test strip becomes saturated prior to excess fluid being absorbed in the portion of the sample receiving pad away from the test strip such that the test strip does not become flooded, the portion of the sample receiving pad positioned away from the test strip being sufficiently sized to absorb the excess fluid. The pinch wall and dam system further includes a dam, sitting on top of the sample receiving pad, the dam preventing the backflow of fluid from an area near the first portion of the pinch wall.

  • Patent number: 10386278
    Abstract: A system for mixing a sample with a combined buffer includes a sampler body, the sampler body including a first reservoir and a second reservoir. The system further includes a first separator forming a first enclosure with the sampler body for the first reservoir. The system further includes a second separator forming a second enclosure with the sampler body for the first reservoir. The system further includes a third separator, in conjunction with the second separator, forming a third enclosure and a fourth enclosure, respectively, both in conjunction with the sampler body, for the second reservoir.

  • Patent number: 9180455
    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.
