Your $1/4 million hospital bill is for a cosmetic rubber case with a bunch of AA's in it or a pump which is required to enforce DRM. That's the absurdity of the medicare industrial complex.
Ben, Love the humor when you are taking stuff apart. It's one of the reasons I enjoy watching your videos. That is such a waste all that single use stuff. Lots of goodies inside for projects. Last time I went to a hospital i kept a few things. some tubing which I used to repair a bug zapper and that thing that tests your lung capacity which Is single use so I kept it and still have it.
The reason they throw away the pump is that the part that "connects" to the patient comes in contact with medical waste. It would have been better if they had a replaceable module that contains the pump and sensors and what not that then connects to the main board. The main part of the unit can be reused without any kind of medical issues and the pump and sensor unit can be tossed.
The model I had had a detachable canister in bulkhead. So the biologicals went into the canister and then they just detach the bulkhead and attach the new one for reuse. I've never seen a small one like Ben had. Mine was the size of a 1980s tape deck.
I'd love to see a dedicated video showing the process of getting a microcontroller like this putting it on a breakout board and getting it to do *something*, the kind of thing we can follow along at home with. Good to see you back.
Ah yes, everything I needed on a holiday Monday in the great white north... Impressions, singing, tear downs, griping at the past, AND BUD. A perfect video.
The wastefulness of these designs can be traced back to some disappointing realities. 1. Sr. Engineers are expensive. 2. Companies prioritize time to market 3. The chips were cheap. So you had/have Jr. Level engineers designing stuff on tight schedules, and their only choice to get everything done is to throw whatever is easier to implement at the problem. With the current chip shortage, I would expect Sr. Level engineers to be more in demand and a trend back to clever engineering instead of brute force solutions.
from wikipaedia The adjective endian comes from the 1726 novel Gulliver's Travels by Jonathan Swift where characters known as Lilliputians are divided into those breaking the shell of a boiled egg from the big end (Big-Endians) or from the little end (Little-Endians)
That puss pump having programmed death kinda makes sense to me. Not as a way to suck more money out of people but actually having a purpose. If the wound keeps putting the stuff out after a time the doctor told you to go get it checked and the pump still works, a lot of people may just keep using it to clean the wound even when it kinda should have stopped and if it's still oozing puss it really needs to get checked. And also so that people wouldn't just store and reuse it. They are single use for a reason. Even if you reuse it yourself in a few years after thorough cleaning, it may give you a hidden extra infection. The device looks cheaply made. Haven't seen those here, but possible that we use those in free healthcare countries too. I hope they don't cost too much in america either. It looks like it shouldn't cost too much.
If you knew what was involved with certifying, manufacturing and auditing a medical device all the complexity, over engineering, and disposability starts to make a lot more sense until you step back and realize it's actually so much worse than you could have ever imagined. In the U.S. the FDA regulates medical devices using a three-tiered classification system. So what exactly does the FDA consider a "medical device"? ❝Any instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part or accessory” that’s recognized as a pharmaceutical or any supplement to them, intended to diagnose, cure, mitigate, preventive, or treat a disease, disorder, illness, medical condition or with the intention to affect the structure or any function of a human or animal body which is not dependent upon being metabolized or other chemical action within or on the body of man or animal for the achievement of any of its primary intended purposes." That's a lot to unpack here are some examples. A bedpan: medical device, an aspirin: medical device, Apple Watch: a medical device, tongue depressors and that stick they poke in your nose when they test you for COVID: medical devices, a breast implant: medical device, a fish oil supplement: not a medical device, a slimfast diet shake: not a medical device, Honey: not... well it depends on the kind of honey and how it's marketed; Honey at the grocery store: not a medical device, Manuka Honey marketed as medical grade is a medical device. How a product is marketed can make all the difference. Early in the Nintendo Wii's heyday Nintendo leaned heavily into the health benefits and highlighted clinical trials and the Wii Fit "effectiveness" at mitigating obesity right up until the FDA came knocking; Nintendo said "it's just a toy we don't want to make it a medical device..." and they ultimately pulled back on the health and fitness claims, walking the same line as most fitness equipment. I trust you have seen 1,000s of commercials for exercise equipment, but none of them claimed it was effective at treating or preventing obesity "Buy our thing, use it 3 times and week in addition to other unspecified things and you will feel great and you can lose weight... Ok so what are the 3 tiers or classes? They are, simply, Class I, II, and III. What then, determines if your medical device is Class I, II, or III? The answer is risk. Each medical device is classified by the assessed risks associated with the device. The higher numbered class, the greater the assessed risk, the higher the regulatory control, which further defines the regulatory requirements for a general device type. Though the policy is straightforward enough, there are nuances. Classification is determined not only by what risk the device poses to the patient and/or the user, but also the intended use of the device along with any specialized indications for its use. For example, a scalpel may have the intended use to cut tissue of a patient, but a manufacturer may have a specialized scalpel specifically designed to make incisions in the cornea. Both may be Class III, and if so both will be required to implement safety and reporting programs that meet the same standards but what is required to meet those standards can be vastly, different. Beyond the classes the FDA currently has classified around 1,700 different device types. These are grouped into 16 medical "panels". Before you can sell your medical device, it has to be assessed, assigned to a panel for further assessment to then assigned to one of the three regulatory classes based on level of control necessary to assure the safety and effectiveness of the device. Also who will operate the device makes a big difference as well, patient or clinician? Note the difference in complexity between the two devices in the video: Both are nasty shit suckers, but the device intended for operation by the patient is far more complex, while the clinician's device was a simple as possible. This of course makes some sense on its surface, sure the patient needs training wheels to try to prevent dumb shit from happening, but what is more if there is an "adverse event" involving the device (which you must disclose to the FDA in your regular reporting) the clinician is qualified and capable of documenting what went wrong where as a patient may not be able to effectively do so (and in practice isn't acceptable) so patient operated devices have sophisticated event logging incase the data is ever needed. That's not to say clinician devices don't, they often do as well, but it's not alway needed. Wait, wait wait, what does all this have to do with ridiculously complex disposable wound suckers? Well before any of that other shit can even begin, you need a device, not a prototype a finished working UL listed (and/or whatever else you might require) ready to ship devices... well not just devices you also need manufacturing and quality control processes, the ones you are actually going to be using, and if your smart you have already started some kind of 3rd party clinical trials, if you've got a hot new bedpan your going to need to find some people and pay them to shit in it. So with this in mind and investment capital being what it is, if you can avoid starting from scratch, and avoid doing anything unecessarly novel there is s huge advantage to doing so, even if that means reworking the hardware architecture, internal safety controls & event logging, housing design, UI, ergonomics and manufacturing processes of an existing hand held implant scanner from another product line (half of which was probably licensed from someone else for that project) just to make your new little 7 day wound sucker. . . . And if you make it all disposable, your boss can get another bonus because you just avoided 6 chapters of additional regulations and saved $2 million dollars in development costs.
I've spent the past 20+ years in medical fields and dealt with both hardware and software and can tell you that most of the device vendors and very small companies that are just looking for a quick profit. Hardly any of them stay in business for very long because they either close doors or get sold to a bigger company that just relabels the products and cycle repeats. Aside from very large devices like CT and MRI scanners, which are regulated more, most of the smaller devices are very cheaply made. It is a very deep and interesting field to learn about though.
I've have experience with those wound vacs, technically they don't shut themselves off my model had a built-in cellular link but not like you would think from like a provider but some sort of other wireless network that they could remotely disable the unit.
I’m glad I brought that stuff in now! I learned more about the wound VAC a.k.a. pus sucker than I had known before! I’m not surprised that they are so wasteful. Especially considering how much they charge the patients for those devices…
It always blows my mind when you take some disposable thing like this apart and find a processor that’s way more powerful than my first desktop, even if it’s just to turn something on and off. It’s like engineers nowadays have never heard of 555s or even PIC16s.
It's supposed to provide a consistent pressure, the the pressure transducer is necessary to regulate the pump since vacuum mod ambient = pressure at the wound.
I don't know about these specific medical devices, but I know some of these one time use devices are recycled back to the original company that basically throws out the housing and reuses the board then sanatizes it all to be sent back to the medical personnel
Ben, I wish I could send you one of the products we design at work. Mobility aids... Powered complex rehab wheelchairs... I was going to see if it was feasible to make custom controls based on PS / XB controllers some of the patients can only use a single finger> Imagine being able to swap out modules depending on the digit(s) they can use..

your Harrison is getting better, not bad. absolutely disgusted at the waste of all these petrochemical plastics and copper and electronic components in the medical field. there has to be a more sustainable way to design tools for sterilisation and reuse
I did some poking around and found one place charging $50, which means the hospital charges $8,000; and the insurance allowable is baked into the cost of the surgery, so it's a black hole.
It's amazing what you can get away with when you are the only manufacturer of a device for an industry that doesn't bill customers based on what things actually cost and is heavily subsidized by the government.
I used to have a mason jar filled with Atmel AT89C4051s, I would program them once and then solder them into stuff as at the time they were the same price as a 20 pin socket... now they are $2+ a piece if you can find them :(
9:30 That entire device can be replaced with a plastic bulb. I had on attached to a tube that ran under my skin all the way across my stomach. The tube was about 5 inches under my skin, and they just stuck a plastic bulb on the end that has a check valve on the end of it. they squeeze the bulb down, which pushes air out of the check valve, then the bulb tries to spring back into its original shape creating a slight amount of pressure. as the wound seeps, the bulb draws the goo into itself. when the bulb is full, they take it off and replace with a new one (or they empty it, i can't quite remember if the bulb gets reused). The whole plastic bulb thing is called a Jackson-Pratt device. There is a paper about them titled "How Much Blood Could a JP Suck If a JP Could Suck Blood?" and yes that is the actual title of the paper lol
I've brought around for 2 weeks a really uncomfy plastic thing that sucked blood plasma or other gunk out of a fresh surgery I had a few years ago. it had zero electronics, it just was a pressurized plastic cylinder with a thin tube running up my wound. I had trouble sitting or sleeping for 2 weeks, but no MCUs were ever wasted in my convalescence.
I was an R&D engineer in an FDA compliant medical device design company. The cost of the chips was minuscule in comparison to the waste spent in business development and marketing.
Classic barometry! Original barometer was a glass tube filled with mercury which had a known density, changes in atmospheric pressure caused a linear, proportional change in the height of the mercury in the tube! Hence, mm of mercury!
Enjoy your content. Understand that youtube burnout is real. I'm ashamed of the number of half finished projects I have. I'm amazed at your output. Oh, and I would like to be the 100th person to say mmHg is millimeters of mercury.
"64-128K A little on the low side"??? Back in my day...[insert monologue from middle-aged guy reminiscing about coding on 2K AVRs] Also that Rossmann impression was on point lol!
Second (gun) device is a wound irrigator. I saw it used in knee replacement surgery. Used pretty much for a few seconds. Bonus was free batteries (this was before eneloop).
Interesting how you've got both ends of the spectrum there. The first one just using a split battery pack to provide some rudimentary motor speed control without any electronic components whatsoever, and the second being incredibly over-engineered but doing basically the same job.
9:30 its possible that it only works for 7 days cuz it doesnt have a replacable ooze disposer or so the machine doesnt get too dirty after prolonged use
reusing microcontrollers out of trash! gee, i try to do this but always fail to get verry basic things working on them, assuming i could get a working compiler
00:50 Yup, used in surgery. For example during a hip replacement to wash out the blood and bone swarf after drilling out the hip. Connected to a bag of saline and a vacuum.
mm of Hg stands for millimeters of mercury, a measurement of pressure or vacuum. for instance your blood pressure 120/80 is in the units of mm Hg (aka Torr.)
Would you consider making videos with an overdub explaining your thought process for some of the more technical things? I have an interest in your channel, but will never have the amount of experience you do in things like "an I squared CE prom".
Hey man, screw you im subscribing out of spite. This is like my 5th sub on YT ever. But for real this was pretty awesome to learn and listen while I work on a car. Although, stumbled upon your channel for a reason. Would you mind if I pick your brain about some tech sometime?
You would think there are other types of gauzes which could be used to abosorb wound puss without the need of this horrific amount of single use waste...
Sometimes, a switch between 4 and 8 batteries looks more normal for a sucker than a trashable one with data saving eprom sending data to the nazis about the resistance of the sucker to know the density of the blood clots ...😂 You know, let's say all the medical care prices are paying for those chips for no reason to kinda invest in arm?
...yes, of course? the devices should be designed for sterilisation to reduce the insane amount of waste of valuable or non-renewable resources. they're currently not because the people who make and the people who buy this equipment aren't held democratically accountable for the wasting they do; they get to externalise the cost

"64-128K A little on the low side"??? Back in my day...[insert monologue from middle-aged guy reminiscing about coding on 2K AVRs]
Also that Rossmann impression was on point lol!
Second (gun) device is a wound irrigator. I saw it used in knee replacement surgery. Used pretty much for a few seconds. Bonus was free batteries (this was before eneloop).
Must be a good time for scavengers.
God, just cables with proprietary connectors in the medical field could cost up towards $280 for a cable that's less than half a meter long.
Interesting how you've got both ends of the spectrum there. The first one just using a split battery pack to provide some rudimentary motor speed control without any electronic components whatsoever, and the second being incredibly over-engineered but doing basically the same job.
9:30 its possible that it only works for 7 days cuz it doesnt have a replacable ooze disposer or so the machine doesnt get too dirty after prolonged use
reusing microcontrollers out of trash! gee, i try to do this but always fail to get verry basic things working on them, assuming i could get a working compiler
00:50 Yup, used in surgery. For example during a hip replacement to wash out the blood and bone swarf after drilling out the hip. Connected to a bag of saline and a vacuum.
I should send you one of my wireless disposable insulin pumps to see what you find in there.
17:55 this random hair flying by (above 100ms/s center frame)
Really cool video I like that i2c sniffing bit
What do you mean "in the PAST"? It's probably still in production...
Are all geniuses "mad"?
No, but it helps apparently lol
Being a genius is not normal in and of itself. So geniuses often come off as a bit odd.
Even I know MM/Hg is millimeters of mercury.
I may not be the first to say this...mmHg=millimeters of mercury.
Metric people would know that instantly.
To answer your question about how much it cost the big version of these is about $600 per day.
Wow! Bud is so large now, it's so cute when he's still a kitten! Now a bit fat.
Bud is living his best life.
I hope you will do something with this chip in the near future. Maybe do an arduino that stops working after time up for example code.
We watch because we love yah bud!
Where's the sound?
"Stop Sucking" -Ben Heck, 2022
mmhg millimetres of mercury...
For further clarity, mmHg is a unit of pressure. 760 mmHg is equivalent to one atmosphere.
instructions unclear... to turn off - pull batterys out
lol
no sounds
mmHg represents millimeters of mercury pillar
No sound for me. Using a Pixel 6 Pro - Android 13 Beta 2.
You've taught me a few things here Ben!
Ben's a content beast! I dig it all! Thanks Ben ( :
You should make Bud the first ARM-powered cat using this chip. Better, stronger, faster...
So great!I have one of these in my to disect pile in the shop
mm of Hg stands for millimeters of mercury, a measurement of pressure or vacuum. for instance your blood pressure 120/80 is in the units of mm Hg (aka Torr.)
CORRECTION: now the chair is aerodynamic
Speed holes!
Would you consider making videos with an overdub explaining your thought process for some of the more technical things? I have an interest in your channel, but will never have the amount of experience you do in things like "an I squared CE prom".
Hey man, screw you im subscribing out of spite. This is like my 5th sub on YT ever.
But for real this was pretty awesome to learn and listen while I work on a car.
Although, stumbled upon your channel for a reason. Would you mind if I pick your brain about some tech sometime?
Therapy device = sucks grossness out of wound; Ben Heck = sucks data out of therapy device. Either way, this video "certainly does suck!" jk, ben
" 'you just lost 10 subscribers!'..." Let's be honest, the people that would un-sub because of that.... have, already. :-)
A box of 10 Pulsavacs costs only $2672.99 - in case anyone wants one from an actual medical supply company 🤣🤑🤣
Your comment on Endian, made me think of the song by Antrax - Indians
Awe Kitty!🥰💕
As a European... leaded solder is my unobtainium 🙂
You would think there are other types of gauzes which could be used to abosorb wound puss without the need of this horrific amount of single use waste...
It's called someone willing to dress it. With no medical background, no training...
mmHg = millimeters of mercury. Tiny vacuum measurement
Either you're mute or I'm deaf. Or both.
Same here, no sound
Working fine for me
mm\hg is a measurement of vacuum it stands for millimeters of mercury i only know that from working on cars lol
Sometimes, a switch between 4 and 8 batteries looks more normal for a sucker than a trashable one with data saving eprom sending data to the nazis about the resistance of the sucker to know the density of the blood clots ...😂 You know, let's say all the medical care prices are paying for those chips for no reason to kinda invest in arm?
Going to be at this years MRRF?
mmHg is millimeters of mercury
Mmhg millimeters of mercury
why no audio?
Can microcontrollers really take heat that long and still work?
Yes.
I'm worry about Uncle Ben keep debunking these device will draw attention from the makers...
It's really gross that you refer to someone you don't know is Uncle Ben.
@@yackablejohnson1485 I watch 95% of his video, and he feel so friendly, why can't I call him Uncle Ben? If you don't think so it's your choice.
@@johnsonlam like Uncle Derek from SSFF. why not?
do you really want them to reuse a medical device?
...yes, of course? the devices should be designed for sterilisation to reduce the insane amount of waste of valuable or non-renewable resources. they're currently not because the people who make and the people who buy this equipment aren't held democratically accountable for the wasting they do; they get to externalise the cost
