Abstract

The present disclosure relates to a device for collecting one or more biological samples comprising a housing and a collector element, wherein the collector element is configured to allow the passage of liquid, and wherein the collector element extends between a first end and a second end, the first end of the collector element protruding out of the housing for collecting the one or more biological samples, the second end of the collector element being arranged within the housing, and wherein the housing comprises a plurality of hooks for engaging the collector element.

First claim

1 . A device for collecting one or more biological samples comprising a housing and a collector element,
wherein the collector element is configured to allow the passage of liquid, and wherein the collector element extends between a first end and a second end, the first end of the collector element protruding out of the housing for collecting the one or more biological samples, the second end of the collector element being arranged within the housing, wherein the housing comprises a plurality of hooks for engaging the collector element.

2 . The device according to claim 1 , wherein the front end of the housing has an opening in which the collector element is arranged, wherein the hooks are formed on an inner surface of the opening.

3 - 17 . (canceled)

18 . The device according to claim 1 , wherein the front end of the housing has an opening in which the collector element is arranged, wherein the hooks are formed on a separate element which is held within an inner surface of the opening.

19 . The device according to claim 1 , wherein the hooks are designed such that the forces needed for inserting the collector element into the housing are lower than the forces needed for removing the collector element out of the housing.

20 . A device for collecting one or more biological samples comprising a housing and a collector element,
wherein the collector element allows the passage of liquid, and wherein the collector element extends between a first end and a second end,
the first end of the collector element protruding out of the housing for collecting the one or more biological samples,
the second end of the collector element being arranged within the housing,
wherein the part of the collector element which is arranged within the housing is glued to the inner surface of the housing.

21 . Device according to claim 1 , wherein the collector element is soft and/or flexible such that the anchor element can extend at least partially into the collector element.

22 . Device according to claim 1 , further comprising an abutment surface or a stop for limiting the movement of the collector element into the housing.

23 . Device according to claim 1 , further comprising a container for storing liquid.

24 . Device according to claim 23 , wherein the liquid is a buffer solution and/or a reagent solution.

25 . Device according to claim 23 , wherein the housing comprises or encloses a channel for guiding the liquid stored in the container to the collector element.

26 . Device according to claim 23 , further comprising a valve and/or release mechanism for opening a passage from the container to the channel so that liquid stored in the container can enter the channel from the container and reach the collector element.

27 . Device according to claim 26 , wherein liquid stored in the container can reach the collector element through the channel when the valve and/or release mechanism is open, wherein at least part of the liquid can pass through the collector element by gravity acting on the liquid when the container is in a position vertically above the collector element.

28 . Device according to claim 23 , wherein the volume of the container can be reduced to squeeze liquid from the container into the channel.

29 . Device according to claim 23 , wherein the volume of the container can be reduced such that liquid is released from the container into the channel and passes through the collector element.

30 . Device according to claim 1 , further comprising a cap element which can be fitted on the housing on the side on which the collector element is arranged.

31 . Device according to claim 30 , wherein an element for indicating and/or measuring a reaction between a reagent and the at least one biological sample is arranged within or on the cap element.

32 . Device according to claim 31 , wherein the element is indicating the pH value of the mixture of the liquid from the container and of the at least one biological sample.

33 . Device according to claim 30 , wherein the cap element comprises a reagent which is released to the mixture of liquid from the container and of the at least one biological sample.

34 . Device according to claim 30 , wherein the cap element comprises an element comprising a reagent which is released to the mixture of liquid from the container and of the at least one biological sample.

35 . Device according to claim 30 , wherein the cap element comprises a window which is arranged such that a user can at least partially see the element for indicating and/or measuring a reaction between the reagent and the at least one biological sample.
