A recently filed patent (Publication Number: US20230182129A1) describes a test device for analyzing body fluids. The device consists of a housing that can hold a test component, an inlet for receiving body fluid, and a reservoir that connects the inlet to the test component.

In one embodiment, the inlet is a capillary tube, which allows for precise and controlled delivery of the body fluid to the test component. The reservoir is located in the upper wall of the housing and can be a recess with a surface area equal to or smaller than the volume of body fluid required by the test component. This ensures that the reservoir can hold enough fluid for the test without excess spillage.

The test component is positioned below the reservoir, forming a lower boundary for it. The upper wall of the housing forms the boundary of the reservoir and may have projections that extend into the inner cavity of the housing. These projections can have openings positioned over the test component, allowing fluid from the reservoir to flow onto the test component. The projections may also extend partially along the test component, further directing the fluid flow.

Another embodiment of the test device includes a projection from the upper wall of the housing that extends into the cavity and contacts the test component. This projection directs fluid from the reservoir along at least a part of the test component. The projection may extend from the boundary of the reservoir and have an opening positioned over the test component. It can also extend partially along the test component.

The housing may have means to elevate the end with the inlet, which can be achieved through projections from the lower wall of the housing. This elevation helps with the flow of fluid from the inlet to the reservoir and the test component.

Overall, this patent describes a test device with a unique design that allows for efficient and controlled delivery of body fluid to a test component. The various embodiments provide different configurations for the inlet, reservoir, and projections, offering flexibility in design and functionality.
