Artificial Intelligence To Medical Robotics

(XENEX GERM-ZAPPING ROBOTS)

                                                                                   ABSTRACT

A robot may be considered as a machine with built-in intelligence, called artificial intelligence. The paper presents a short introduction about the disinfectant robots in the context of artificial intelligence. Hospitals are synonymous with cleanliness and now an academic medical center is taking disinfection to futuristic levels. Nicknamed “little Joe” a 3-foot upright cylindrical robots provide the finishing touches to room sanitation. A rotating telescopic head emits cidal ultraviolet (UV) rays for 15 minutes in closed, unoccupied rooms to systematically kill germs dead.      

                                    Introduction

         Several disciplines of Science, Technology and Engineering are involved in building a suitable robot for a specific application, thus making the field of robotics a highly interdisciplinary area of specialization. To build intelligence into the robot, powerful computers with artificial intelligence, artificial neural networks, fuzzy logic, genetic algorithms etc., are involved.
Artificial intelligence is a theory. The base object is the agent who is the "actor". It is realized in software. Robots are manufactured as hardware. The connection between those two is that the control of the robot is a software agent that reads data from the sensors decides what to do next and then directs the effectors to act in the physical world

           It's a staggering modern-day irony that the most common complication for hospital patients is acquiring an infection during their visit In the U.S., approximately the same number of people that  die from hospital acquired infections (HAIs) is almost equal to as the number that dies from  AIDS, breast cancer and auto accidents combined. Patients acquire HAIs while receiving care at hospitals for another condition. These infections, such as MRSA (methicillin-resistant Staphylococcus aureus) and C. diff (Clostridium difficile), can devastate and kill patients. Current CDC statistics show that in the United States, 1 in every 25 patients will contract an HAI and of those, 1 in 9 will die. HAIs cost the healthcare industry upwards of $30 billion dollars annually.If this isn't bad enough, the tragedies from deadly superbugs within healthcare facilities are on the rise and will likely continue as the last lines of antibiotics fail without any new drugs moving fast enough up the pipeline to help.
Fortunately, an alternative to medication promises to vastly improve the disinfection of hospital rooms,  UV light emitting robot.


       I.            XENEX BOT:
              Additionally, a system of reflectors allows the light to be focused on areas that have high-touch surfaces, such as door handles and light switches. In case someone enters the room when the bot is in operation, a motion detector halts operation to prevent accidental exposure to humans. Combined with improved hand-washing and sanitation practices along with recent calls to replace all stainless steel with copper, these bots can help fight hospital-acquired infections without relying on antibiotics, which contributed to these superbugs in the first place.
An increasing number of hospitals are employing the device. The first facility to do so was Cooley Dickinson Hospital in Massachusetts, which had previously reported site-acquired infections of 1 out of every 129 patients. After bringing the Xenex robot to the hospital in 2011, an 82 percent drop was seen with C. diff.alone.


     II.            FUNCTIONS OF DISINFECTANT ROBOT:

                Using a pulsed-xenon UV lamp, the portable bot shoots out 120 flashes of light per minute. Each pulse lasts a thousandth of a second each, and a typical treatment runs for 10 to 20 minutes. The UV rays pass through the outer wall of a bacterium and damage its DNA, making it impossible for it to mutate or reproduce. This stops the pathogen from propagating or being harmful. 

 III.             ADVANTAGES:

·          operation of the robots has less environmental impact than discarded containers or the heavy use of disinfectants
·          Xenex Pulsed Xenon UV disinfection technology disables pathogens that remain after standard room cleaning. This additional layer of protection takes a matter of minutes, adding minimal time to the cleaning process.
·          The pulsed UV light destroys viruses, bacteria and bacterial spores without human contact or use of chemicals.
·          A recent study showed that the Xenex bot is superior to bleach at destroying one of the most concerning pathogens in hospitals, the resilient Clostridium difficile (C. diff) that can survive for months on surfaces. While cleaning with bleach only destroyed 70 percent of the pathogen in rooms, a 15-minute treatment using the pulsed UV treatment eliminated 95 percent, leaving six-times fewer bacteria around
·          Additionally, a recent investigation produced results consistent with these findings for the common antibiotic-resistant Staphylococcus aureus (MRSA).


  IV.            Disadvantages


·              The issue, of course, is cost. At a price of about $80,000 each, a large facility would require two Xenex bots to keep rooms sterilized routinely. While this may seem steep, treatment for a single case of MRSA infection can run $28,000, as CNN reported last year.
·              Other hidden costs, such as training, are minimal.
CONCLUSION
As the fourth leading cause of death in the US, hospital-acquired infections are increasingly been seen as costly on top of being a tragic end for people seeking care. Hopefully, more institutions will implement Xenex bots and the technology can continue to make strides.
