Update: Contactless Device to stop nighttime dry mouth (build log)

Hi guys,

last time i shared the first 3d printed version of a device I built to help a close friend with dry mouth during radiation treatment.

the feedback and all of your comments made me very happy so i promised an update and here it is.

I went to china to source components and trying to move away from a 3d printed iteration. met some cool redditors who reached out after my last post but i have not yet decided to sign any commitments just yet.

how i adressed everyones main concern (hygiene): i switched from 3d printing to aluminum, switched to a borosilicate water reservoir and decided to rework the PCB to keep pumping the water in a circle in order to not leave any zones that the uv-c can‘t reach.

difficulties i faced are mainly the PCB at the moment, to get the pressure of the pump right and make everything steplessly adjustable AND i wasn‘t aware that there’s golden week in china so unfortunately i am not able to keep building here now so everything will take some more time but stay with me please.

i know it‘s not the update i wanted to share but i still wanted to show the progress and ask for your input again and of course if anyone wants to join my journey you‘re more than welcome.

Thanks everyone for your time let me know if you like the new design

So i built a contactless device to stop nighttime dry mouth

Hi everyone

a close friend of mine had to go through radiation therapy for cancer. Among all the side effects there was one nobody really had a solution for: extreme dry mouth during the night.

He was waking up every 30 minutes with his mouth feeling like sandpaper, unable to sleep or recover. Regular humidifiers just fogged up his room without reaching his mouth, and sipping water every half hour meant he never got a single hour of continuous sleep.

so i decided to craft something myself and came up with a 3d printed headset humidifier. it is silent and doesn‘t cover touch your face like a mask does so nothing will interrupt with sleeping.

i 3d printed it withABS-like resin (SLA) on Elegoo Saturn 4 Ultra printers and cured the finish a bit.

so a prototype is built, and works and i know this has the potential to help millions of people in all kinds of usecases.

i‘m looking for an experienced co-founder who has the knowledge how to build something up and would like to join me turning this into a startup.

questions, every criticism etc. is welcome let me know their thoughts or join the journey.

thank you for listening and i‘m looking forward to hear your thoughts

Can Shenzhen build my Prototype?

Hi everyone!

So I’m stuck in the infamous hardware founder gap between prototype and mass production.

after countless nice conversations with alibaba sellers i decided to take matters into my own hands and i‘ll be flying to shenzhen 03rd of September.

i guess my question is do the kind of small workshops that handle this actually exist in Shenzhen, and where do you find them? Huaqiangbei or are there only sellers?

I’m developing a fairly simple wearable consumer electronics device. working prototype exists and functions, I have video of it running but i won‘t have it with me for reasons…

i already have a functional prototype built by an external engineering firm), full CAD, PCB schematics, layout, Gerbers, Firmware source,…

I need functional units for validation with early customers. Not mass production basically just a pilot batch that looks like a real product.

any pointers on where to start, or what I should line up before I get there, would be hugely appreciated

many thanks everyone

Premium hardware for post-op recovery. C-Sample ready, 84% gross margin, bypassing CAC through B2B clinic distribution.

hello everyone.

i have developed and patented a modular high end device optimized for nasal surgery recovery.

Market & Core Pain Point:

there are over 4 million nasal procedures performed annually (including aesthetic rhinoplasties, septoplasties, and reconstructive surgeries). According to clinical post op surveys over 90% of these patients state that severe dry mouth and the resulting sleep deprivation are their absolute number one complaint during the first weeks of recovery.

this problem is caused by 100% forced mouth breathing due to internal nasal packing, swelling secretion etc…

blue ocean product. current market alternatives are saline sprays, gels, or lozenges which completely fail because they require the patient to be awake to use them meaning sleep is constantly interrupted every single hour.

the device uses ultra sound to deliver targeted, continuous hydration directly to the breathing zone while the patient sleeps.

I have positioned it strictly as a personal care/wellness device in order to completely avoid long medical regulatory bottlenecks.

The numbers & monetization models:

Direct Sale (UVP): €499 (Estimated COGS at scale: ~€80 via anodized aluminum, PVD-coated accents, modular base ecosystem).

B2B Rental Model (Recurring Revenue)

Instead of just buying, clinics can rent the units out to patients for their 1 or 2 week recovery window. This opens up a highly scalable recurring revenue loop for us through specialized sanitization kits, refills and maintenance cycles managed after each rental.

Current State

Patented. Phase 2 mechanical CAD finalized. Functional high-end prototype (C-Sample) is fully operational and built.

IP/Entity

Operating via a clean US LLC with multi-currency banking set up.

Distribution

Instead of wasting capital on facebook or google ads, we use a pure B2B2C loop. We partner directly with private ENT surgeons and plastic surgery clinics.
Whether they choose the direct sale or the rental model, the clinics get a 40% cut.

Since the surgeon has 100% of the patient’s trust during post op consultation, a direct recommendation drives the utilization.

Looking for angels or strategic partners with experience in consumer electronics scaling, tooling/manufacturing funding, or medical/wellness distribution to back the first production

if that sounds good to you and you’d like to hear and see more let‘s connect. i speak german english and spanish the rest i can translate!

Best way to find Investors for a hardware startup in Dubai?

hey guys,

i’m a solo founder with a tech/recovery startup based in Dubai and just finalized the high end prototype of my hardware device.

the device is aimed at the premium personal care market, economics are strong with high to very high margin (from what i was able to research).

I already have a solid b2b pipeline in a very niche sector for the first batch (consisting of international specialists in this very niche)

since the product development is done and the market interest is (at least) validated i’m now looking for seed capital to fund the first production run and set up the corporate structure here.

my question now: what’s the most efficient way to connect with local angels, vcs, or tech networks in Dubai for physical products?

if possble i‘d like to avoid the generic online application black holes if possible.

appreciate any input! thank you very much in advance

Edit to clarify (cause people in my DM‘s asking): It‘s not skincare and not a gadget. it‘s blue ocean technology and solves a real problem.
