Diagnostics is an aspect of health care that is extremely important, but due to its routine nature, is also a perfect candidate for automation. Diagnostics and analysis also require a high degree of precision, allowing room for the use of computers and robotics. By combining material handling with analysis equipment and diagnostic software, an all in one unit creates feasible medical application solutions. Let us examine an example of how effective material handling allows all of these parts to work together as a whole.

Material Handling

Most medical application solutions for diagnostics consist of liquid handling and multiple precise movements. These movements will carry loads between one and three kilograms and move at a rapid pace Imedical Healthcare Solutions of one meter per second. Materials will move in two dimensions and must start and stop quickly while all of these actions have to occur with precision and be effective over time as part of heavy duty usage.

As part of the analysis, materials will undergo multiple steps for sample preparation, distribution, dilution, and reagent additions along with chemical reactions. One analysis will typically include all of these steps, in a specific sequence, performed the same way every time; this is the perfect environment for a computer controlled system.

Truly flexible systems will be able to handle different types of tests on a single unit allowing for a significant cost savings to be achieved. Ideally, medical application solutions would only require that personnel load the samples and regents and then specify a program to run. Then, the controller would be able to perform the precise, complicated motions without supervision.

DC Micromotors That Power Diagnostics

Diagnostic systems have to be flexible and powerful to handle the complex work done in clinical and hospital labs. All components also have to be small in order to work with closely arranged holders and plates as well as be reliable so healthcare providers can depend on their equipment. DC micromotors provide all of those requirements. DC gearmotors provide the heavy load capacity while only occupying a small space.

A sample DC micro-motor is sized at 57 millimeters in length and 26 millimeters in diameter. This DC micro-motor, despite its small size, is capable of handling of handling several kilograms of material while only weighing a fraction of that total itself. Operating voltages range from three to 36 volts for efficient battery operation. High precision DC gearmotors are able to generate 512 pulses per revolution for an extremely precise movement scale for small movements and exact positioning.
