Minimally Invasive Blood Analyser Using Semiconductor Chip

Abstract: In this method of invention very minute quantities like micro liters of blood will be extracted from finger using a small prick and the collected quantity of blood will be distributed into single valve carbon nano tubes of multiple numbers to conduct multiple diagnostics test. In this method apparatus works based on Lambert Beers law and advanced nano level measuring techniques. In this method of invention a special kind of chip with capacity to handle multiple analytical functions is designed. The chip will record the image of single wall carbon nano tubes after adding respective reagents and compare the changes with standard library of reactions. It has the ability to transmit the data from these tests to multiple users. Chip also will give the data which can be used for colour comparisons and record nano metric liquid chromatographic movements. In this method of invention an unique single wall carbon nano tubes are used as test tube like holders which can take nano litres of liquid volumes and subjected to various titrimetric tests. The challenge of filling these nano test tubes is addressed with nano metric liquid dispersion mechanism designed using collagen fibers with salt solutions, which respond to external pulsed current. Using advanced electronic circuits, femto second timer control is used to disperse liquid into single wall carbon nanotubes

Specification

Description

A small blood drop of 0.1 micro liters blood will be taken from prick on a finger which will be absorbed into a semiconductor chip. The chip absorbs blood and distribute into various nano capillaries and using fine microscope the rate of filling into nano capillaries will be measured and standardized. Using EDTA and other reagents serums will be extracted from the blood. Different reagents will be added to these capillaries using preplanned array of reagent addition mechanism and the results will be analyzed using appropriate sensors.

An unique semi conductor chip is designed to receive data from multiple number of nano capillary tubes which are added with various reagents. The chip records data like change in the color, change in image using pinhole cameras and liquid chromatographic movements and compare with mass spectro meter standard sample results. A nano optical fiber made up of graphene is used to transport the data and retrieve data.

An instrument of single wall carbon nano tube capillary holder is produced to hold nano liters of liquids. These nano capillaries are arranged in rows and columns of a matrix which has preplanned analytical test patterns. Single valve carbon nano tubes of fixed length are arranged in a fashion where that can be subjected to various light exposure of spectra from UV to IR regions and reflections will be captured with image sensors to analyze and compare with standard samples of ,macro levels. A nano metric liquid dispenser with help of collagen fibers are used to disperse liquids into these capillaries. At this stage different concentrations of salt solutions used to deliver liquid deliveries.

Background of invention

Many methods of introducing samples into the analyser have been invented. This can involve placing test tubes of sample into racks, which can be moved along a track, or inserting tubes into circular carousels that rotate to make the sample available. Some analysers require samples to be transferred to sample cups. However, the effort to protect the health and safety of laboratory staff has prompted many manufacturers to develop analysers that feature closed tube sampling, preventing workers from direct exposure to samples., Samples can be processed singly, in batches, or continuously.

The automation of laboratory testing does not remove the need for human expertise (results must still be evaluated by medical technologists and other qualified clinical laboratory professionals), but it does ease concerns about error reduction, staffing concerns, and safety.

6. Brief description of drawing:

Finger is pricked and a blood drop is placed on collagen fiber on the top

Pulses are given to the fiber using femto timer controller When the pulses are given to the fibre, it obsorbs blood and distributes it into nano carbon tubes

Different kinds of reagents are present in different nano carbon tubes Specially designed chip with pin hole camera will monitor blood levels and colour changes occurs due to reagents present carbon nanotubes

Data is processed by the chip and sent to multiple users
