Sampling and testing device for the human or animal body
First Claim
1. A device for testing a biological sample, the device comprising:
- a rigid housing;
a sampling portion located outside of the housing, the sampling portion comprising flexible sheet material that projects from and is bendable independently of the housing and is adjustably conformable to a part of a human or animal body, the flexible sheet material having a surface area of at least 20 cm2 and at least a portion of the flexible sheet material being an absorbent target portion configured to receive a biological sample directly from the body;
a test portion located at least partially inside the rigid housing, the test portion being spaced from the absorbent target portion, the test portion comprising one or more label-holding areas including labels that form labelled complexes with one or more biological entities present in the biological sample and comprising one or more test zones configured to immobilize the labelled complexes to indicate the presence or absence of one or more biological entities in the sample, anda fluid flow path, connected between the absorbent target portion and the test portion, that transfers biological sample received at the absorbent target portion to the test portion by capillary action.

Abstract
A device (1) is provided that is configured to indicate the presence or absence of one or more biological entities in a biological sample. The device comprises a sampling portion (11), the sampling portion comprising flexible material adjustably conformable to a part of a human or animal body, at least a portion of the sampling portion being absorbent and configured to receive a biological sample directly from the body; and a test portion (12) in fluid engagement with the sampling portion, the test portion comprising one or more test zones (14). The sampling portion and test portion are configured such that at least a portion of the sample received by the sampling portion is transferable to the test portion such as to contact one or more of the test zones, and wherein each test zone is configured to indicate the presence or absence of one or more biological entities in the sample.

23. A test device for receiving and testing a nasal discharge sample from a nose, the test device comprising:
-
a housing; a sampling portion projecting from the housing, the sampling portion comprising flexible sheet material defining two flexible wings, the two flexible wings being pivotable relative to the housing and configured to be positioned on opposite sides of the nose, the flexible sheet material having a surface area of at least 20 cm2 and comprising an absorbent target portion to receive a nasal discharge sample from the nose; and a test portion located at least partially inside the housing, the test portion being spaced from the absorbent target portion, the test portion comprising one or more label-holding areas including labels that form labelled complexes with one or more biological entities present in the biological sample and comprising one or more test zones configured to immobilize the labelled complexes to indicate the presence or absence of one or more biological entities in the sample, a sealed reservoir containing liquid, the sealed reservoir located at least partially inside the housing; a mechanism operable to break or burst the reservoir to release the liquid from the reservoir, wherein the released liquid is transferred to the absorbent portion by capillary action to increase the fluidity of nasal discharge sample received at the absorbent portion; and a fluid flow path, connected between the absorbent target portion and the test portion, that transfers nasal discharge sample received at the absorbent portion to the test portion by capillary action.
