DETAILED DESCRIPTION

[0020] The present disclosure is directed to a self-serve automated apparatus, including devices and kiosk embodiments, that can be employed in a variety of settings, such as airports, for testing individuals prior to immigration or boarding; in hospitals in conjunction with both patient admitting and visitor clearance; as well as in schools and other facilities requiring fast and accurate pathogen screenings for large numbers of people. Using adaptive learning and a remote database, the present disclosure can quickly analyze a sample and provide a real time report, allowing the individual being tested to receive an accurate and complete health check while the results of the test are stored in the database for subsequent authorized use and retrieval as may be needed.

[0021] The present disclosure provides an apparatus which may be in the form of a free-standing kiosk, allowing fast processing of samples. Such kiosks may be located in high traffic environments, such as airports or entertainment venues, where the analysis of many samples must be performed rapidly. The apparatus and method have high-assurance for tracking and indexing.

[0022] The present disclosure comprises a kiosk collection apparatus that is intended to provide onsite accurate pathogen testing by the analysis of human-derived samples, and includes means for identifying and documenting the individual to be tested; means for drawing samples pursuant to a collection protocol including sample verification; and on-site analysis of the sample. The analysis can be performed through microprocessor control at the kiosk or the raw data can be forwarded to an off-site recipient for analysis and return of results.

[0023] The kiosk may also include a self-contained cleaning system to sterilize the sample collection chamber in the kiosk after a sample is collected, permitting the next test to commence within minutes. Collection means for the sample, such as an internal bin, may be provided to collect the tested samples with safety, and may include appropriate waste sterilization compartments.

[0024] FIG. 1 presents one illustrative embodiment that provides the system for analysis of a specimen taken from an individual. As seen therein, the system is in the form of a kiosk that acquires a sample for analysis as well as identity validation data from the individual from whom the sample is taken. An authorized and trained operator of the kiosk manually takes the sample, such as by a swab, which is loaded into the kiosk through specimen intake drawer 5. The kiosk can deliver human interface instructions through a video display or touch-screen display 1. The kiosk acquires identification and validation information of the individual using biometric interfaces, which may be in plurality, such as including a video camera function via a video camera 2 and audio input and output functions via audio input and output 3. Identification cards, tokens or RFID are validated through card reader slot function via a card slot 4, as known in the art. The audio input and output 3 may be a speaker/microphone combination.

[0025] To prevent unauthorized operation of the kiosk, the operator is provided with an access or identification card, which must be inserted into the card slot 4 to operate the kiosk. This ensures that a test is performed only by an authorized agent. In alternate embodiments, the kiosk can integrate various commercially-available mechanisms for recording and confirming the identity of the agent. The agent can also be validated through use of the biometric interfaces.

[0026] In contemplated alternative embodiments, the system can establish the identify of an individual physically present in proximity to the kiosk by scanning the individual's passport or other official identification through a reader/scanner, either as a separate interface (not shown) or incorporating such functionality into the video camera 2. Further confirmation of the individual's identity as matching the individual on scanned document may be performed through other biometric characteristics. The kiosk can provide audio instructions by audio output and video instructions, prompted on touch-screen display 1, and can provide the individual with instructions as needed. All such functions may be under the control of the system kiosk's main microprocessor, suitably programmed as known in the art. The individual can also enter information through the touch-screen.

[0027] With the identity of the individual being confirmed, a microprocessor-controlled analysis system in the kiosk analyzes the sample. The analysis system may include a high definition microscopy component camera system with analytical software for imaging analysis and labeling. The kiosk bundles the analysis results with both the identification on the authorized agent and the individual tested and transmits the data to a remote electronic data storage facility. The data processing modules employed provide for encoding and privatization of all data. Such data processing modules may provide random research identifiers and encode private individual data into private electronic data storage encrypted at multiple levels. In some instances, the data delivered into remote data storage, which may be cloud-based, can be de-identified and privatized so that the results of the analysis, but not the individual associated with the results, is stored. This may allow bulk analysis of results, such as to measure trends and identify potential “hot spot” areas, without endangering the privacy of the tested individuals. After the analysis at the kiosk and transmission of the data to the remote server(s), the data is automatically purged from the kiosk's memory; it never remains on the kiosk device.

[0028] Depending on the nature of the pathogen to be identified and the sophistication of the analysis software, the analysis may be conducted at the kiosk under microprocessor control, with communication to remote databases as needed. Alternatively, the raw test data may be transmitted to a remote facility for analysis, with the results transmitted back to the kiosk. In either case, upon completion of the analysis a report is provided to the kiosk operator and, if proper, shared with the individual tested. Depending on the results, the individual may be cleared for passage or otherwise advised or directed to seek treatment or other processing.

[0029] FIG. 2 illustrates the procedures in the acquisition and recording process, setting forth components that may be utilized for the procedures. The physical mechanism may use sealed chambers, enclosed in polished stainless steel or other metal, polymer or other synthetic material encasements, as known. The encasements provide functionality for self-sanitation, such as by use of an autoclave process, which in turn may include one or more of chemical, radio-frequency, and UV options. It is further contemplated that embodiments may use radio spectrum radiation or radioisotopes for different levels of sterilization inside an appropriate encasement.

[0030] As presented in FIG. 2, the sample specimen is received on an input tray at 200. The tray is moved into a transfer chamber at 202. The chamber is prepared for receipt of the sample by incurring a pre-process sanitation at 204. Such process may include the use of appropriate cleaning and sanitizing fluids as well as heat, as shown at 206.

[0031] The actual samples to be analyzed may be received by individual cartridges arrayed in a multi-cartridge feeder or carrier at 208. A single cartridge receives a specific sample, and delivers it into the sterilized transfer chamber at 210. An electronic record is created of the sample identification and other information to create an appropriate chain-of-custody record at 212.

[0032] The sample material received from the individual is placed on a media cartridge at 214. The cartridge subsequently passes into a plurality of chambers, where it is exposed to various fixing and analysis procedures as appropriate to the analysis desired illustrated at 216-220. Such procedures may also include sample sterilization and de-contamination.

[0033] FIG. 3 illustrates an embodiment of a flexible, translucent, mesh-type material 6 which can support the receipt of various of reactive-agent chemical and biological-reactive materials as may be required for sample analysis. The porous mesh material 6 is attached to a rider material 7 that may be non-porous, flexible, and appropriate for visible light photography. For example, the material may be a rubber formulation or more specifically a synthetic plastic/petroleum composite formulated to meet different temperature and light requirements as appropriate. The mesh structure may contain reactive materials for the pathogen to be analyzed, with micro- and/or nano-structures, allowing the apparatus to records the reactions with a microscopic photographic process.

[0034] Other techniques for analysis of the specimen on the capture material may include fluorescent photographic electronic sensors, optionally with magnifying and filtering lenses. Such sensors can record colors, heat, intensity, and size variations produced by the chemical reactions within the media substrate material, providing additional data to assist the sample analysis.

[0035] The specimen capture media may advantageously be of a translucent media to facilitate the acquisition of microphotographic recordings, allowing multiple captures are performed as an analysis is performed. Such captures may employ variations in the applied light spectrum to capture unique multiple chromatic recordings of the media. As may be appropriate, temperature adjustment may be performed while recording, whereby the temperature variations are recorded and combined with resulting visual recording.

[0036] FIG. 4 illustrates a media material dispensed from a continuous-web feed mechanism. This media cartridge, which may be of a barrel-construction 8, is loaded with a roll of media 9 which are dispensed or fed out from the barrel-construction 8 through a conveyor feed mechanism 10. The feed mechanism applies the required reactive and activation materials onto the individual mesh media and provides cutting and separation into individual sample-receiving elements. The individual media elements are carried by a chamber conveyor 11 into a sterile chamber for receipt of a sample, sample analysis and subsequent destruction.

[0037] FIG. 5 presents the procedure for the chain-of-custody and evidentiary functions. The key functionality performed by the system components is that each individual media unit is identified and recorded with individual and tracked serialization. This serialization is validated prior to specimen processing and recorded for official record in final processing.

[0038] As illustrated, a media cartridge is loaded for sample receipt at 500. It is assigned an individual identifier at 502 and a reference photograph of the cartridge is taken at 504 and associated with the identification data set assigned at 506. The sample to be received by the cartridge is received and verified at 508, and is transferred to the cartridge at 510. A photographic record of the transfer cartridge is created for audit tracking and recording at 512.

[0039] The cartridge with sample then proceeds to an acquisition chamber for commencement of the analysis procedure at 514, during which analysis photographic and other records are created to document the analysis at 516, along with a timestamp and other data to document the cartridge location and analysis performed at 518.

[0040] FIG. 6 describes a method and process for establishing and capturing identification information of an individual from whom a sample is to be taken. As shown therein, the system establishes contact with the individual by issuing an audible (or other) prompt for the individual's name at 600. The response is captured at 602, concatenated with other data at 604, and then used to initially validate the identity of the individual at 606. If the validation fails at 608, an exception is raised at 610, and further processing is ended. The individual can then discuss the situation with the kiosk operator, perhaps with a repeat of the validation process.

[0041] Elf the validation is successful the individual is prompted for a face photograph at 612, and the photo is taken and acquired by the system at 614. Again, the photo is compared to another photograph of the individual, such as a passport photo, and with verification success confirmed at 616, recording of the identification procedure is authorized at 620 and recordation performed at 622, with the information added to the serialized record for the media cartridge to be used for sample collection. If the photographic validation fails, an exception issues at 618 for re-test or other appropriate action.

[0042] FIG. 7 illustrates the procedure for processing and storing data associated with a sample analysis. As shown therein, secure communication channels are established at 700 and a full record, including material characterized by a sensitive identifiers is transmitted to a primary secure data store at 702. To allow transmission of data to other facilities that do not require access to a full record, including “sensitive identifiers” in the record, such identifiers are scrubbed from the record at 704. Such identifiers may include the tested individuals name, personal information, passport or other identification documents, and the like. The remaining “cleansed” record may continue to contain data directly associated with the test or analysis performed, such as audit photograph and serialized media cartridge identification 706, information directly related to the pathogen(s) tested for and identified 708, 710. The cleansed record is then compiled and processed into a desired standard form to enable entry into data banks and cross-referencing at 712. With such processing completed the record is delivered at 714 to the appropriate recipients, such as a research library or institution.

[0043] In some situations, some sensitive identifiers may remain in a scrubbed record, depending on the nature of the recipient for the information. For example, medical or hospital personnel having a relationship with the individual tested may be granted access by the individual to receive the results of a test for entry into the individual's personal medical record. Information regarding such authorized access by be provided by the individual during an initial “interview” when the individual's identity is entered into and recorded by the kiosk.

[0044] The present system allows integration of sample analysis and data collection by a kiosk or other testing station to be both maintained by the kiosk as well as passed to other facilities for review and correlation with data for the tested individual obtained from other authorized sources, as well as with a virus library or libraries with adaptive learning capabilities such that an accurate result of the test can be determined and the libraries themselves can be updated with the results of the test. The results of the analysis can is transmitted back to the kiosk for use by the agent and individual being tested.

[0045] With adaptive learning and predictive analysis matched against the libraries, the kiosk can differentiate among a negative pathogen sample test; a positive pathogen sample test; and an unknown pathogen sample. The latter two results can provide grounds for further examinations and potential refusal of passage and isolation.

[0046] In addition to use at airports and similar travel locations and hospitals, the kiosk system can be used in a variety of venues where a large number of people needed to be checked quickly and accurately, such as sports venues and large social gatherings.

[0047] Similar to the above free-standing apparatus for acquisition and analysis of a biological sample from an individual, the present disclosure also provides a method for acquisition and analysis of a biological sample from an individual. The method may include operations of: receiving identifying data of the individual; receiving the biological sample for the individual; providing a unique identifier for the biological sample and association with the individual; and conducting an analysis of the biological sample and generating a report of analysis results.

[0048] In some embodiment, all of the foregoing operations are under control of a microprocessor located in a free-standing apparatus.
