Description
POINT OF CARE DIAGNOSTIC PLATFORM
BACKGROUND OF THE INVENTION
Field of the Invention:
The present invention relates generally to a point of care diagnostic system that has a plurality of modules and associated cartridges, and more particularly, to a point of care diagnostic system that includes a plurality of modules that share common QC
protocols.
Description of the Related Art:
Blood and other body fluid tests are important diagnostic methods in patient care and treatment. The reliability and the accuracy of the tests are critical in correctly diagnosing the patient and administrating proper treatment. The Food and Drug Administration (FDA) has established numerous quality standards for the various blood or body fluid tests. Monitoring the test process is beneficial in producing reliable and accurate test results.
One way of monitoring the test process is periodically performing the monitoring test on standard test samples. The monitoring test results are compared with expected results to verify the accuracy of the test processes or correct the test instrument or process when appropriate. (n this approach, the test processes are assumed to generate consistent result between the monitoring tests.
Another way of monitoring the test process is including standard test samples in the test process. This approach is suitable for a test process that performs tests on multiple samples. The test results on the standard test samples are compared with expected results to verify the accuracy of the test processes. In this approach, the test processes on real samples are assumed to generate result consistent with those on standard test samples.
These monitoring processes are time and cost inefficient. They are deficient in meeting the needs of point of care, e.g., hospital emergency roomldepartment, test processes. In addition to being reliable and accurate, an emergency room test process should be simple to operate and generate diversity of analytical results fast.

In the Figure 1 (d) embodiment, host computer 14 and user interface 16 are both integrated with multiple, multi-cartridge modules 12. In the Figure 1 (e) embodiment, host computer and user interface 16 are integrated with multiple, single-cartridge test processing modules 12.
Point of care diagnostic platform 10 includes a plurality of cartridges 20, illustrated in Figure 2. Cartridges 20 include but are not limited to cardiac , fertility, kidney, coagulation, electrolyte and hematology panel, molecular diagnostics and chemistry panels, and the like.
Each cartridge 20 can include a dock 22 for receiving a sample tube, an air dock 24 that can be engaged by a module 12, a rotary valve 26, which can also be engaged by a module 12, a calibration chamber 28, waste chamber 30, sample/calibration flow path 32 which is coupled to a detector, sample out flow 34, sample pressure channel 36 and a flow cell 38 which is a detection chamber.
Cartridges 20 can have wet and dry chemistries and at least one substrate that carriers a chemistry. Examples of various wet and dry chemistries are listed in table 1.

In one embodiment, cartridges 20 can directly accept a blood sample from a standard blood draw, sample tube 40 which can include a pressure needle 42 and a sampling needle 44, as shown in Figure 3. This can be achieved by, (i) piercing the cap of the standard blood draw tube 40 needles 42 and 44, which deliver low pressure air to force the sample through the other needle into the cartridge 20, penetrating the cap with a single needle and withdrawing fluid directly using a vacuum, and the like. Cartridges 20 can be configured to retain and seal fluids. This can be achieved by using selective pressurization of reagent and sample reservoirs, which forces the fluids into cartridges and through flow cell 38 into waste chamber 30, that can be an integral part of cartridges 20. All fluids in cartridges 20, including patient samples, can remain within the cartridge 20.
As illustrated in Figure 4, modules 12 can be configured to be engaged with the cartridges 20 to produce pneumatic movement of fluids in the cartridges 20.
The pneumatic pressure is applied by an external pump 46 through the dock 22 on cartridge 20, Figure 2, which is engaged by module 12. Module 12 can include a valve, 48, a vent 50 to atmosphere and a channel 52 that is coupled to cartridge 20. The pneumatic pressure is directed to specific reservoirs and samples in cartridge 20 using valve 48 mechanism to cause selective reagent flow. Cartridge 20 includes a sample application area 54. Optics 56 are included in module 12 and an optical window 57 is included in cartridge 20. At the cessation of reagent flow, excess pressure is vented through vent 50 to atmosphere to stop the flow. Platform 10 can provide self-testing of modules 12, to provide for monitoring and detection of fluid flow. Various electrical and optical properties of the samples and reagents allow continuous monitoring of flow cell contents and are compared to expected transition values, as illustrated in Figure 5.
Figure 6 illustrates a cross-sectional view of one embodiment of a cartridge 20.
Cartridge 20 can have a number of different flow channels, including but not limited to air, sample and reagent flow channels 58, 60 and 62. Flow channels 58-62 can be created by depressions in both the top and bottom surfaces of the cartridge 20. Flow paths 58-62 can then be sealed with a vapor barrier 64.
Referring again to Figure 4, pressurization of specific sample or reagent containers provided by pump 46 are selectively directed to sample and reagents containers in sequence, providing an outflow directed by a valve to detection chamber 38 or other location, as needed, in sequence and with precise timing. The sample and reagents can flow through an area of controlled temperature to prepare them for precise analysis prior to or during introduction to detection chamber 38. After analysis the reagents and sample remain in the cartridge 20 in waste region 30, although the sample tube 40 can be removed by the operator for subsequent use if desired.
Each module 12 can include a processor 56 (Figure 1 (b). Host computer 16, in combination with a processor 56, determines a test protocol for a cartridge 20. A fluid control mechanism in the cartridge 20 is then actuated that permits a flow of a patient sample with liquid chemistries and waste materials. This can occur without exposing an operator of platform 10 and the patient, to a transfer of a patient sample into the cartridge 20 without exposure to the chemistries. Cartridges 20 are designed to isolate biohazards in a cartridge 20 from an operator of the cartridge 20 or the patient. Blood samples from patients are introduced to the cartridges 20 while isolating biohazards in the cartridge from an operator.
5 In one embodiment, cartridges 20 are designed to work with whole blood. This eliminates the requirement of a secondary process to remove the cellular components which may interfere with the testing. This additional separation is both time consuming and error prone. In the cartridge, the separation of cells is done automatically by providing a barrier which is penetrated by the analyte to be measured by excludes the 10 cells from analytical contact, except in the case of hemotalogy, where the cells themselves are the subject of measurement.
Cartridges 20 can include electronic identifiers, including but not limited to bar-coded identifiers, with information for test protocols, and lot expiration dates. Cartridges can also include serialized identification.
15 In one embodiment, placement of a cartridge 20 in a module 12 begins an initiation of the module 12. When a cartridge 20 is inserted into a module 12 it can be sensed automatically. The bar code of cartridge 20, with its unique sample, are read.
This initiates the sequential operation of the fluid movement and detection.
In another embodiment of the present invention, platform 10 includes a plurality 20 of modules 12 each sharing common QC protocols. A list of possible QC
protocols is found in table 2.
As illustrated in Figure 4, modules 12 can be configured to be engaged with the cartridges 20 to produce pneumatic movement of fluids in the cartridges 20.
The pneumatic pressure is applied by an external pump 46 through the dock 22 on cartridge 20, Figure 2, which is engaged by module 12. Module 12 can include a valve, 48, a vent 50 to atmosphere and a channel 52 that is coupled to cartridge 20. The pneumatic pressure is directed to specific reservoirs and samples in cartridge 20 using valve 48 mechanism to cause selective reagent flow. Cartridge 20 includes a sample application area 54. Optics 56 are included in module 12 and an optical window 57 is included in cartridge 20. At the cessation of reagent flow, excess pressure is vented through vent 50 to atmosphere to stop the flow. Platform 10 can provide self-testing of modules 12, to provide for monitoring and detection of fluid flow. Various electrical and optical properties of the samples and reagents allow continuous monitoring of flow cell contents and are compared to expected transition values, as illustrated in Figure 5.
Figure 6 illustrates a cross-sectional view of one embodiment of a cartridge 20.
Cartridge 20 can have a number of different flow channels, including but not limited to air, sample and reagent flow channels 58, 60 and 62. Flow channels 58-62 can be created by depressions in both the top and bottom surfaces of the cartridge 20. Flow paths 58-62 can then be sealed with a vapor barrier 64.
Referring again to Figure 4, pressurization of specific sample or reagent containers provided by pump 46 are selectively directed to sample and reagents containers in sequence, providing an outflow directed by a valve to detection chamber 38 or other location, as needed, in sequence and with precise timing. The sample and reagents can flow through an area of controlled temperature to prepare them for precise analysis prior to or during introduction to detection chamber 38. After analysis the reagents and sample remain in the cartridge 20 in waste region 30, although the sample tube 40 can be removed by the operator for subsequent use if desired.
Each module 12 can include a processor 56 (Figure 1 (b). Host computer 16, in combination with a processor 56, determines a test protocol for a cartridge 20. A fluid control mechanism in the cartridge 20 is then actuated that permits a flow of a patient sample with liquid chemistries and waste materials. This can occur without exposing an operator of platform 10 and the patient, to a transfer of a patient sample into the cartridge 20 without exposure to the chemistries. Cartridges 20 are designed to isolate biohazards in a cartridge 20 from an operator of the cartridge 20 or the patient. Blood samples from patients are introduced to the cartridges 20 while isolating biohazards in the cartridge from an operator.
5 In one embodiment, cartridges 20 are designed to work with whole blood. This eliminates the requirement of a secondary process to remove the cellular components which may interfere with the testing. This additional separation is both time consuming and error prone. In the cartridge, the separation of cells is done automatically by providing a barrier which is penetrated by the analyte to be measured by excludes the 10 cells from analytical contact, except in the case of hemotalogy, where the cells themselves are the subject of measurement.
Cartridges 20 can include electronic identifiers, including but not limited to bar-coded identifiers, with information for test protocols, and lot expiration dates. Cartridges can also include serialized identification.
