Device for assaying analytes in bodily fluids

Abstract

A device for determining the presence and/or quantity of one or more analytes in a sample of human body fluid has a container for receiving a sample of body fluid, with an interior that is delimited by a base and by a circumferential surface. It further comprises at least one test strip and a holding element for receiving and holding the one or more test strips. The holding element is designed such that it has a shape corresponding and adapted to the peripheral circumferential surface of the container. The device further comprises an elongate sampling element having an absorbent sampler that takes up the sample of body fluid and by means of which the sample of body fluid is transferred into the container. Further, the base of the container has a central elevation via which the sample of body fluid can be conveyed from the sampler, by compression thereof on the elevation, to the at least one test strip.

         2 . The device of  claim 1 , wherein the elevation is a hemispherical elevation arranged centrally on the base inside of the container. 
     
     
         3 . The device of  claim 1 , wherein the elevation comprises ridge-shaped elements which extend centrally from the elevation towards the base for conveying the sample of body fluid to the peripheral edge of the base of the container. 
     
     
         4 . The device of  claim 1 , wherein the base of the container has a depression in the area of and extending around the circumferential surface, for receiving the sample of body fluid flowing down from the elevation. 
     
     
         5 . The device of  claim 4 , wherein the at least one test strip, with its absorbent section taking up the sample of body fluid, is adapted to the shape of the depression. 
     
     
         6 . The device of  claim 1 , wherein the sampling element, at its end remote from the end with the sampler has a closure means for closing the container after the sampling element has been introduced into the container. 
     
     
         7 . The device of  claim 6 , wherein the closure means is provided with blocking means for blocking the removal of the sampling element from the container after the sampling element has been introduced into the container. 
     
     
         8 . The device of  claim 6 , wherein the closure means has a pierceable self-sealing sampling element for permitting, after it has been pierced, access to the interior of the container even after the closure means has been fitted onto the container. 
     
     
         9 . The device of  claim 1 , wherein the sampling element and/or the sampler has means for indicating the presence of an amount of the liquid sample that is sufficient for determining the presence and/or the amount of one or more analytes in the sample. 
     
     
         10 . The device of  claim 9 , wherein the means are an indicator strip of an absorbent material present in the sampling element. 
     
     
         11 . The device of  claim 10 , wherein the indicator strip has a zone for indicating the presence of the sufficient amount. 
     
     
         12 . The device according to  claim 10 , wherein the sampling element has a marking for indicating the minimum travelling distance of the sample of body fluid through the indicator strip. 
     
     
         13 . The device of  claim 1 , wherein the container is a cylindrical container with a circular base and wherein the holding element has a shape adapted to the circular cross section of the circumferential surface, such that the holding element is formed peripherally over the inner circumference of the circumferential surface. 
     
     
         14 . The device of  claim 1 , wherein the container is a cuboid container with an essentially rectangular base, having two short and two long edges forming the essentially rectangular base, and wherein the holding element has a shape adapted to the rectangular cross section of the circumferential surface such that that the holding element is formed peripherally over the inner circumference of the circumferential surface. 
     
     
         15 . The device of  claim 14 , wherein the base of the container has means by which the sample of body fluid can be conveyed from the elevation to the long side edges of the base. 
     
     
         16 . The device of  claim 1 , wherein the holding element is shaped with pretensioning and clamped into the container. 
     
     
         17 . The device of  claim 1 , wherein the holding element is at least partially bonded to the circumferential surface on the inside of the container and/or of the base. 
     
     
         18 . The device of  claim 1 , wherein the holding element has recesses in which the test strips are respectively arranged.
