US 11,440,013 B2 · System for preparing a sample

Abstract

A device is provided comprising a receiving chamber for receiving a patient's sample, a first reagent reservoir and a second reagent reservoir. The receiving chamber may be configured for receiving at least an end portion of a sample collecting element, with the patient's sample being collected by that sample collecting element. The first reagent reservoir may generally be configured to accommodate a liquid reagent which may include a lysing agent, i.e. the liquid may be a kind of a lysis buffer. Likewise, the second reagent reservoir may generally be configured to accommodate a dry reagent which may include magnetic particles. The device may further comprise at least one of the following two actuators, a first actuator for supplying a first reagent from the first reagent reservoir to the sample and a second actuator for supplying a second reagent from the second reagent reservoir to the resulting mixture.

A device for preparing a patient's sample before analysis, comprising:

a housing having a central axis;
and
an actuator;
wherein the housing comprises a receiving chamber and a reagent reservoir,
wherein the receiving chamber comprises an opening;
wherein the receiving chamber is configured for receiving at least a portion of the patient's sample through the opening,
wherein the reagent reservoir is configured for receiving a reagent,
wherein the actuator is rotatable relative to housing about the central axis of the housing,
wherein rotation of the actuator:
closes the opening of the receiving chamber, and
causes contact between the reagent and the patient's sample, such that the patient's sample is at least partially mixed with the reagent
wherein the actuator is configured to cut a portion of a sample collecting member,
wherein the sample collecting member protrudes out of the receiving chamber as the actuator rotates about the central axis of the housing.
