Navage sorta makes what you are describing.
It’s a neti pot of a device that has 2 tanks. One that will hold a saline solution and one for the ‘waste’ water.
You insert the nozzles into both nostrils and push the button and one pushes water into one nostril while the other has a light suction that pulls the water out the other and into the waste tank.
I’ve used one for a couple years and it legit works. Great for allergies and sinus issues. Just google it or look it up on Youtube.
mainly that you don't have to worry about doing it over the sink or holding it just perfect so the waste goes in the sink and not on the faucet or the cabinet or whatnot. I personally prefer just emptying the waste container. Also it tries to force you into its proprietary pods but there are plenty of jury rig ways to make it work with your salt solution.
Suction machines are used to remove excess mucus from the sinuses and throat in medical settings. The public should not use these machines because you can accidentally stimulate a nerve in your throat that can cause your heart to slow, beat irregularly, or stop.
A neti pot with boiled (not boiling) salted water is great! In one nostril, out the other, and after 10 crappy seconds, my stuffed runny nose is clear for hours.
A little baking soda to lower the PH takes away some of the unpleasantness. With the right PH, salinity, and temperature, you barely feel the water flowing. You can also add just a drop of baby shampoo to help clean out crusties.
I've been looking for somewhere that sells USP-grade salt and baking soda in bulk so I don't have to waste so much material dealing with the packets, but I haven't been able to find anything legit.
The pre-measured packets are really convenient though. If you're nose is really blocked it's good to use between 1 and 2 packets for a hypertonic solution.
when you go to the dentist, the dentist and/or hygenist will usually work with two tools. If they need to rinse your teeth, they'll first blast them with some ice cold water, and then they'll stick a straw-looking thing in your mouth to suck up the water they just skeeted in. Similarly, when they're drilling your teeth, they'll use the little straw fellow to suck up the tooth dust so you don't get weird shit in your lungs.
It's like an oral shop vac, where your mouth is the mess. They use them so they don't have to stop and let you spit. OP has Problems™ and wants to stick one of these things in their nose.
OP, please, just blow your nose or take a decongestant if you're sick (NOT oral phenylephrine because that shit is useless). If you avoid blowing your nose because you get bloody noses all the time you can actually get that part of the inside of your nose cauterized. I used to get at least one nosebleed a day, and it was genuinely life changing for child me when the doctor stuck that swab in my nose. It was painful for a sec or two, but I only get nosebleeds once or twice a year now.
EDIT: netti pots are good, just make sure you practice good hygiene with those. Very hot and steamy showers and putting damp heat on your sinuses is also quite helpful in my experience as a lifelong severe allergy sufferer.
I just asked copilot. The salt water has a couple of benefits over pure water; it's less irritating to mucous membranes, it thins mucus more effectively, and it has modest antimicrobial effects.
I use the neilmed sinus rinse almost every day and it has been life-changing. Last time I got sick there was no stuffy nose or runny anything because I just cleaned it all out it was phenomenal.
My guess would be that the hypertonicity of the salt water causes water to move out of your nose's tissues through osmosis, reducing swelling, while the water clears out the mucus and stuff clogging it up.
