Abstract
In a testing kit for bodily fluids, a device is provided which combines a specimen collection component and a testing component, which are integrated into a single, inexpensive element that is readily manufactured. This permits testing by collecting a specimen with the device, then simply dropping it into a predetermined quantity of buffer solution.
Claims25
An integrated collector/test device for a body fluid, comprising a body having a first end constructed to capture and retain a quantity of the body fluid and an indicating element mounted on the body and constructed to undergo a visible change when exposed to the body fluid in a predefined condition.
A method for using an integrated collector/test device for a body fluid, the device including a body having a first end constructed to capture and retain a quantity of the body fluid and an indicating element mounted on the body and constructed to undergo a visible change when exposed to the body fluid in a predefined condition, the method comprising the steps of:
- collecting a sample of the body fluid at the first end;
- deposting the device in a predetermined quantity of buffer solution so that the sample is in the solution;
- and
- waiting for the indicating element to provide a visual indication.
A master form useful for the manufacture of integrated collector/test devices for a body fluid, comprising a main body made of a sheet material having a length dimension and a width dimension, a plurality of through-holes formed in the body so as to extend along the length dimension an area on said body spaced from the through-holes and constructed to undergo a visible change when exposed to the body fluid in a predefined condition, a device being created by cutting a strip from the master form so as to include a through-hole and a portion of the area.
A method for manufacturing an integrated collector/test device for a body fluid, said method making use of a master form including a main body made of a sheet material having a length dimension and a width dimension, a plurality of through-holes formed in the body so as to extend along the length dimension an area on said body spaced from the through-holes and constructed to undergo a visible change when exposed to the body fluid in a predefined condition, said method comprising the step of cutting a strip from the master form so as to include a through-hole and a portion of the area.
A method for creating a dispensable set of integrated collector/test device for a body fluid, said method making use of a master form including a main body made of a sheet material having a length dimension and a width dimension, a plurality of through-holes formed in the body so as to extend along the length dimension an area on said body spaced from the through-holes and constructed to undergo a visible change when exposed to the body fluid in a predefined condition, said method comprising the steps of:
- cutting a plurality of strips from the master form so that each includes a through-hole and a portion of the area;
- removeably mounting the plurality of strips on a backing sheet;
- a device being dispensed by separating one of the strips from the backing sheet.
