Microcomputer control syringe machine

This Microcomputer control syringe machine is an improvement over prior art which uses rubber tubes with stoppers. Prior art, the tubes would include a rubber sleeve and rubber plunger which are not airtight. As a result, the tubes often get contaminated with dust particles and other harmful substances. In addition, the tubes could break if they were vigorously shaken or worked upon because they could vibrate. Another problem was that the doctor had to keep the syringe assembly in place when treating the patient.

This invention eliminates these complications. Because the cannula and other needle adapters are sealed within the tube itself, there is no air or other contaminants to worry about. Also, because all of the components are sealed away from the working surface, there is no need for the doctor to constantly keep the syringe assembly in place. All that is needed is simply to replace the tubing after each use.

The last type of syringe assembly that I will discuss was a very novel solution that my professor designed while he was completing his Ph.D. entitled, "styptic growth on a non-porous metal surface". In his paper, Dr. Kumar showed how he could coat metal surfaces with a strong organic dye and then inject dye into a surgical wound to introduce color and antiseptic into the wound. His styptic growth syringe was comprised of two metal rings that contained dye suspension while a small piston syringe contained the needle adapter and the hypodermic needles.

As with the prior art designs, this design required that the syringe contained both a cannula and a needle hub. The concept was rather ingenious as it provided a means to deliver the medication without having to introduce the drugs through the skin as would have been the case with the prior art designs. Kumar's solution required that the syringe contained both a cannula and needle hub so that the syringe could be used multiple times with each user having its own drug injection container.
