发明名称 Vent configuration for a blood sampler
摘要 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.

主权项 1. A blood sampler device, comprising: 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; and a blood collector adapted to be inserted into the sampler body, the blood collector including a first end and an opposed second end;an opening adjacent the second end;a seal surface extending around a circumference of the blood collector;a pair of ribs formed in a region adjacent to the seal surface; andat least one vent formed between the pair of ribs, the at least one vent in the region adjacent to the seal surface, the ribs forming the at least one vent, the vent being adapted to allow air to escape from the chamber as the blood collector is inserted into the sampler body, and the vent comprising a top shoulder extending inwardly from the seal surface in a direction toward the opening, the vent forming a gradually sloped surface adapted to smooth a flow profile of air flowing over the gradually sloped surface, wherein the seal surface engages the seal device to form a substantially airtight seal upon complete insertion of the blood collector into the sampler body.
