Abstract
The present disclosure provides a device for testing an analyte in a fluid sample and a receiving device for treating the fluid sample, wherein the receiving device is used for receiving an absorbing element; the receiving device comprises a accommodating chamber and the chamber comprises a piercing element that is movable in the chamber, wherein the piercing element has a first position and a second position in the accommodating chamber, and configured to pierce the first sealed chamber; the accommodating chamber comprises a treatment solution for treating a fluid sample. The assay device and receiving device of the present disclosure treats a sample and quickly obtain the assay result, which is especially suitable for quick assay of a roadside drug.
Claims18
A combination comprising:
- a detection device having at least one detection element capable of indicating presence of an analyte;
- a collecting device having a fluid passage and an absorbing element in fluid communication with the fluid passage, the collecting device being connectable to the detection device such that the fluid passage will be in fluid communication with a fluid inlet of the detection device;
- a receiving device including a receiving cup engageable with the detection device and a piercing element slidably movable in the receiving cup, the piercing element having a piercing structure at a distal end thereof so as to rupture a pierceable material in the receiving cup and release a treatment solution;
- and
- the detection device defining a recessed area adjacent to the fluid inlet, the recessed area forming a chamber to receive excess liquid from the collecting device, a baffle being in the chamber formed by the recessed area.
A combination comprising:
- a collecting device having a fluid passage and an absorbing element in fluid communication with the fluid passage;
- a receiving device including:
- a receiving cup defining:
- a first chamber in which a treatment solution is contained by a pierceable material;
- a second chamber adjacent to the first chamber but being separated therefrom by the pierceable material, the second chamber having a smooth inner surface having an inner diameter;
- and
- a piercing element slidably movable in the receiving cup, the piercing element having a first tube portion and an axially-aligned second portion, the second portion carrying a piercing structure at a distal end thereof, the piercing structure defining at least one through hole,
- wherein the absorbing element is receivable in the first tube portion of the piercing element and an outer surface of the first tube portion is in sealing engagement with the smooth inner surface of the second chamber of the receiving cup via at least one seal such that movement of the piercing element reduces a sealed space defined between the at least one seal and the pierceable material.
