Ultrasonic misting to aid fluid removal from COVID19 or pneumonia patients

This is just an idea and would require a feasibility study to confirm whether it is workable and useful. The idea is to use ultrasound to convert fluid building up in lungs into a mist that the lungs can more readily expel, rather like cigarette smoke.

Ultrasonic transducers have been used for many years to make fog or mist for trivial theatrical effects and garden ornaments. Even cheap transducers from Amazon can convert 400ml of water to mist per hour each.

It is also commonplace in radiation treatment to overlap beams from different directions so that normal tissue is unharmed but intensity is high enough to achieve the desired effect where it is needed. This would work for ultrasound beams coming from different directions too. That would prevent fluid from being misted in the wrong places.

Another existing technology used for ultrasonic loudspeakers uses interference between beams from multiple transducers to create audible effects at any point in space.

My suggestion is to combine these existing technologies to make a close-fitting vest or harness fitted with an array of ultrasonic transducers that could be worn by patients suffering fluid build up in their lungs. Conventional ultrasonic imaging could identify locations of fluid build up and then ultrasonic beams could then be targeted precisely to convert some of that fluid to mist, allowing it to be ejected more easily from the lungs during breathing, instead of building up and effectively drowning the patient. Whole regions could be scanned to mist from large volumes at once, or different amounts of mist could be produced from particular problem areas. The effect would presumably look similar to people breathing out cigarette smoke. The rate at which fluid could be converted to mist is far greater than the rate at which it builds up, so even though not all of the mist would be ejected, it could still achieve the goal.

This might not work. It may be too hard to cause misting in fluid not in direct contact with a transducer. It may be too difficult to cause misting of problem fluid without causing problems in nearby tissue or bubbles in blood vessels. Obviously a lot of engineering design would be needed even if it could work, but expertise to do that is out there and suitable vests could possibly start be manufactured within months.

15 basic technologies could help reduce exposure

  1. In lifts (elevators if you’re a Yank), or indeed any room that gets a lot of people traffic and may therefore spread infections, a simple passive infrared detector could monitor whether there are people in it, and if not, a strong UV light could be activated, which would help kill any viruses and bacteria present.
  2. Portable UV sterilisation boxes could reduce contamination on face masks in between uses so that it’s clean again before you go back out there
  3. Tethered drones equipped with strong (and directional) UV lights could continuously sterilise surfaces in some key areas. Untethered drones that can rapidly recharge could also help.
  4. High powered air filters that can remove viruses could be installed in train carriages, hospital wards and corridors etc.
  5. Industrial and domestic smoke and particulate scrubbers could be adapted to reduce the concentration of  airborne viruses in any area with high concentrations of people. Systems that use plasma or static electricity also exist.
  6. In corridors, either of these air cleaning mechanisms could be used alongside blowing the air in a vortex to maintain a narrow channel of purified air, so that limited filtering can still maintain a safe corridor.conjuction with high pressure
  7. Voluntary ‘digital air’ subscription could enable ‘cookies’ or markers to be collected by your mobile phone as you walk around. If other subscribers that have been in contaminated areas are nearby, your phone could alert you so you can stay clear.
  8. Just as we already have pollen and pollution forecasts, virus detectors could produce real-time information on areas to avoid, or that are safe to visit for exercise.
  9. Bongs (bottles that pass the air through a liquid) could be adapted to use rapid anti-viral fluids). Ultrasonic transducers could further continuously mist the anti-viral medium so that a large air volume is exposed to allow longer decontamination periods with a small amount of fluid.
  10. Spiky net face-masks (like an orange bag with soft spikes on each junction) could prevent people touching their faces.
  11. People could voluntarily wear ‘smart bindis’ made from thermal colour-changing materials similar to those used in cheap fish tank thermometers. You could tell at a glance if someone has a fever or not.
  12. Face masks and surface covers could be made from fabrics that contain nanospikes, attached to pizoelectric vibration devices that can send ultrasonic waves through the materials, physically rupturing virus and bacteria.
  13. Piezoelectric misting could also be used to make forehead mist generators that occasionally bathe the face in anti-viral mist
  14. People living nearby should be able to combine online orders to maximise logistics efficiency
  15. Gloves with antiviral insides that sterilise hands when worn. Obvious alternative is to sterilise inside and outside.

 

 

 

The rise of Dr Furlough, Evil Super-Villain

Too early for an April Fool blog, but hopefully this might lighten your day a bit.

I had the enormous pleasure this morning of interviewing the up-and-coming Super-Villain Dr Furlough about her new plans to destroy the world after being scorned by the UK Government’s highly selective support policy. It seems that Hell has no fury like a Super-Villain scorned and Dr Furlough leaves no doubt that she blames incompetent government response for the magnitude of the current crisis:

Dr Furlough, Super-Villain

“By late January, it should have been obvious to everyone that this would quickly grow to become a major problem unless immediate action was taken to prevent people bringing the virus into the country. Flights from infected areas should have been stopped immediately, anyone who may have been in contact with it should have been forcibly quarantined, and everyone found infected should have had their contacts traced and also quarantined. This would have been disruptive and expensive, but a tiny fraction of the problem we now face.  Not to do so was to give the virus the freedom to spread and infect widely until it became a severe problem. While very few need have died and the economy need not now be trashed, we now face the full enormous cost of that early refusal to act.”

“With all non-essential travel now blocked”, Dr Furlough explained, “many people have had their incomes totally wiped out, not through any fault of their own but by the government’s incompetence in handling the coronavirus, and although most of them have been promised state support, many haven’t, and have as Dr Furlough puts it ‘been thrown under a bus’. While salaried people who can’t work are given 80% of their wages, and those with their own business will eventually receive 80% of their average earnings up to £2500/month whether they are still working or not, the two million who chose to run their small business by setting up limited companies will only qualify for 80% of the often small fraction of income they pay themselves as basic salary, and not on the bulk of their income most take via dividends once their yearly profits are clearer. Consequently many will have immediately dropped from comfortable incomes to 80% of minimum wage. Many others who have already lost their jobs have been thrown onto universal credit. The future high taxes will have to be paid by everyone whether they received support or were abandoned. Instead of treating everyone equally, the state has thus created a seething mass of deep resentment.” Dr Furlough seems determined to have her evil revenge.

With her previous income obliterated, and scorned by the state support system, the ever self-reliant Dr Furlough decided to “screw the state” and forge a new career as a James-Bond-style Super-Villain, and she complained that it was long overdue for a female Super-Villain to take that role anyway. I asked her about her evil plans and, like all traditional Super-Villains, she was all too eager to tell. So, to quote her verbatim:

“My Super-Evil Plan 1: Tap in to the global climate alarmist market to crowd-fund GM creation of a super-virus, based on COVID19. More contagious, more lethal, and generally more evil. This will reduce world population, reduce CO2 emissions and improve the environment. It will crash the global economy and make them all pay. As a bonus, it will ensure the rise of evil regimes where I can prosper.”

She continued: “My Evil Super-Plan 2: To invent a whole pile of super-weapons and sell the designs to all the nasty regimes, dictators, XR and other assorted doomsday cults, pressure groups, religious nutters and mad-scientists. Then to sell ongoing evil consultancy services while deferring VAT payments.”

“Muhuahuahua!” She cackled, evilly.

“My Super-Plan 3: To link AI and bacteria to make adaptive super-diseases. Each bacterium can be genetically enhanced to include bioluminescent photonic interconnects linked to cloud AI with reciprocal optogenetic niche adaptation. With bacteria clouds acting as distributed sensor nets for an emergent conscious transbacteria population, my new bacteria will be able to infect any organism and adapt to any immune system response, ensuring its demise and my glorious revenge.”

laugh cry

By now, Dr Furlough was clearly losing it. Having heard enough anyway, I asked The Evil Dr Furlough if there was no alternative to destroying the world and life as we know it.

“Well, I suppose I could just live off my savings and sit it all out” she said.
