Abstract
The present application relates to: (i) a sampler device for taking a sample of biological fluid, which comprises a capillary component, and a base rigidly connected to said capillary component and provided with a first connector capable of being reversibly attached in a leaktight manner to a second connector of a dispensing device; (ii) a dispensing device which also comprises means for transferring diluting fluid which open into said second connector. The application also relates to a biological analysis apparatus implementing the sampler and dispensing devices and to a method for sampling and dispensing a biological fluid.
Claims17
A device capable of collecting biological fluid comprising:
- a capillary component having a first end, a second end, and an internal conduit extending therebetween, wherein the capillary component is capable of collecting a sample of biological fluid by capillary action at the first end;
- a dispensing device;
- a base rigidly connected to the second end of the capillary component and comprising a first connector reversibly attached in a leak tight manner to a second connector of the dispensing device, so as to create a fluid connection between the internal conduit of the capillary component and a transferring conduit of the dispensing device, wherein the fluid connection is formed via an opening at the base between the second end and the second connector, and wherein the transferring conduit is in fluid communication with and is capable of transferring transfer fluid into the internal conduit of the capillary component via the interface between the first connector and the second connector;
- an injector for pushing a predefined volume of transfer fluid through the transferring conduit and into the internal conduit of the capillary component;
- a measuring container connected to and capable of directly receiving fluid from the internal conduit of the capillary component that is attached to the second connector;
- and
- a displacement portion operatively connected to and capable of moving the second connector:
- in a first position, that allows the capillary component and base to be attached to and removed from the second connector, wherein the first end extends away from the measuring container, and
- in a second position, that allows the transfer fluid issuing from the internal conduit of the capillary component inserted onto the second connector to flow into the measuring container, wherein the first end extends towards the measuring container.
A sampling device for collecting a sample of biological fluid comprising:
- a dispensing device;
- a tube-shaped capillary component having an internal conduit extending between a first end and a second end thereof;
- a base portion at a first end of the capillary component, the base portion further comprising;
- a first connector having lugs reversibly engaged with seats of a second connector of the dispensing device;
- an opening portion in fluid communication with the internal conduit of the capillary component, wherein the opening is between the lugs of the first connector and is configured to sealingly engage with a fluid conduit at the second connector of the dispensing device to form a continuous fluid path from the first end of the internal conduit of the tube-shaped capillary component to the fluid conduit of the dispensing device;
- a measuring container connected to and capable of directly receiving fluid from the internal conduit of the capillary component that is attached to the second connector;
- and
- a displacement portion operatively connected to and capable of moving the second connector:
- in a first position, that allows the capillary component and base to be attached to and removed from the second connector, wherein the first end extends away from the measuring container, and
- in a second position, that allows the transfer fluid issuing from the internal conduit of the capillary component inserted onto the second connector to flow into the measuring container, wherein the first end extends towards the measuring container.
