The present invention relates to a biomedical assay device holder and a method for using the biomedical assay device holder. The biomedical assay device holder has a changeable recess to accommodate different biomedical assay devices and mounts on an assay device connector assembly of an opto-electronic assay device to convert a chromatographic or fluorescent result of the biomedical assay device to a numeral result.
Medical quality has improved during recent years. The efficiency of determining a biomedical assay result and the precision of a biomedical assay result are important for early diagnosis and treatment of a disease. A conventional biomedical assay requires an excessive amount of time in an incubating stage and requires multiple apparatuses in a detection process to produce chromatographic or fluorescent results that could not be obtained rapidly and accurately.
Progressive development of biomedical assay devices, such as biochips, improves quality of biomedical assay results and simplifies biomedical assay procedures. Using an electronic assay device to convert the chromatographic or fluorescent result of the biochip to a numeral result provides an easy way to understand the assay result. Conventionally, biomedical assay devices may be different shapes, be built to different specifications and require specific devices to analyze the chromatographic or fluorescent result of a specific biomedical assay device.
The main objective of the present invention is to provide a biomedical assay device holder and a method for using the biomedical assay device holder. The biomedical assay device holder mounts in a biomedical assay device that mounts on an assay device connector assembly and comprises a base and a changeable recess. The base mounts on the assay device connector assembly. The recess is varied to accommodate different biomedical assay devices and mounts in an assay device connector assembly of an opto-electronic assay device to convert a chromatographic or fluorescent result of the biomedical assay device to a numeral result.
With reference to
A drop of fluid such as blood, urine or saliva is placed on the biomedical assay device and indicates a biomedical assay results by color or fluorescence.
The assay device connector assembly (A) is inserted into an opto-electronic assay device to convert the biomedical assay result to a numeral result.
The base (11) is mounted in the assay device connector assembly (A).
The recesses (12, 12′) is varied to accommodate different biomedical assay devices and mount in the assay device connector assembly (A) of an opto-electronic assay device to convert a chromatographic or fluorescent result of the biomedical assay device to a numeral result and may have a shape selected from a group consisting of circular, rectangular, polygonal or irregular.
The optional removal notch (13) is formed on the base (11) and communicates with the recess (12, 12′).
The optional recognition feature may be formed on the base (11) and be used to differentiate different biomedical assay devices.
The optional reference feature may be formed on the base (11) around the recess (12, 12′) so the opto-electronic assay device will recognize the applicable biomedical assay device specification.
The optional sensor may be mounted inside the base (11), be used to identify an assay device specification of the opto-electronic assay device and may be a radio frequency identification (RFID) device.
A method for using the biomedical assay device comprises steps of (a) preparing a sample, (b) positioning the biomedical assay device holder and (c) reading biomedical assay results of the biomedical assay device.
Step (a) of preparing a sample comprises dropping a biomedical fluid onto a biomedical assay device, placing the biomedical assay device in a biomedical assay device holder and placing the biomedical assay device holder in an assay device connector assembly.
Step (b) of positioning the biomedical assay device holder comprises inserting the assay device assembly into an opto-electronic assay device, identifying and positioning the biomedical assay device using a central point of the biomedical assay device, and optionally step (b1) calibrating the biomedical assay device holder position by multiple optional reference features, at least one recognition feature or a sensor.
Step (c) of reading biomedical assay results of the biomedical assay device comprises converting the biomedical assay results to numeral results.
The method in accordance with the present invention further optionally comprises a step (d) of calculating comprising converting signals of the biomedical assay device to a numeral result. Step (d) may further optionally comprise a step (d1) of generating a calibration curve by a serial concentration of a standard solution.
