Abstract

Devices, systems and methods including a sonicator for sample preparation are provided. A sonicator may be used to mix, resuspend, aerosolize, disperse, disintegrate, or de-gas a solution. A sonicator may be used to disrupt a cell, such as a pathogen cell in a sample. Sample preparation may include exposing pathogen-identifying material by sonication to detect, identify, or measure pathogens. A sonicator may transfer ultrasonic energy to the sample solution by contacting its tip to an exterior wall of a vessel containing the sample. Multipurpose devices including a sonicator also include further components for additional actions and assays. Devices, and systems comprising such devices, may communicate with a laboratory or other devices in a system for sample assay and analysis. Methods utilizing such devices and systems are provided. The improved sample preparation devices, systems and methods are useful for analyzing samples, e.g. for diagnosing patients suffering from infection by pathogens.

First claim

The invention claimed is:

1. A device configured to assay a sample for the presence of pathogen-identifying material, said device comprising a housing, and within said housing, a sonicator having a sonicator tip; a vessel holder configured to hold a vessel having a vessel wall; a sample handling system configured to move said vessel within the housing, wherein the vessel is configured to hold said sample for sonication; a solenoid disposed to urge said sonicator tip towards the vessel wall when said solenoid is activated, wherein the sonicator tip is configured to contact the vessel wall effective to transfer ultrasonic energy from said sonicator to the vessel wall upon operation of the sonicator; a spring disposed so as to urge the sonicator tip away from the vessel wall; and a detector.

2. The device of claim 1 , wherein said sonicator comprises a sonicator horn comprising said sonicator tip, wherein the sonicator tip is configured to contact said vessel wall effective to transfer ultrasonic energy from the sonicator to the vessel wall upon operation of the sonicator.

3. The device of claim 1 , wherein said detector comprises an optical detector.

4. The device of claim 1 , further comprising a communication assembly configured to communicate with a laboratory, a network, or the cloud.

5. The device of claim 1 , wherein the device is configured to apply force to said vessel while applying said sonicator tip to said vessel wall of the vessel.

6. A device configured to assay a sample for the presence of pathogen-identifying material, said device comprising a housing; a sonicator within said housing, said sonicator having a sonicator tip; a sample handling means configured to move a vessel within the housing; a vessel holding means configured to hold said vessel, the vessel having a vessel wall and being configured to hold said sample for sonication; a solenoid disposed to urge said sonicator tip towards said vessel wall when said solenoid is activated, wherein the sonicator tip is configured to contact the vessel wall effective to transfer ultrasonic energy from said sonicator to the vessel wall upon operation of the sonicator; a spring disposed so as to urge the sonicator away from the vessel wall; and a detector means.

7. The device of claim 6 , wherein said sonicator tip is configured to contact said vessel wall effective to transfer ultrasonic energy from the sonicator to the vessel wall upon operation of the sonicator.

8. The device of claim 6 , wherein said detector means comprises optical detection means.

9. The device of claim 1 , wherein said assay for the presence of the pathogen-identifying material comprises an assay selected from the group consisting of detection of the pathogen-identifying material in the sample, identification of the pathogen-identifying material in the sample, and measurement of an amount of the pathogen-identifying material in the sample.

10. The device of claim 6 , wherein said assay for the presence of the pathogen-identifying material comprises an assay selected from the group consisting of detection of the pathogen-identifying material in the sample, identification of the pathogen-identifying material in the sample, and measurement of an amount of the pathogen-identifying material in the sample.

11. The device of claim 1 , wherein said biological sample comprises a sample selected from the group consisting of blood, urine, sputum, tears, material from a nasal swab, material from a throat swab, material from a cheek swab, and another bodily fluid, excretion, secretion, and tissue obtained from a subject.

12. A system comprising the device of claim 1 .

13. The device of claim 1 , wherein said sample handling system is configured to apply force to the vessel while the sonicator tip is applied to the vessel wall of the vessel.
