It sounds like you are talking aboutsome sort of system not unlike the restaurant pagers that exist. I'm not certain if they definitely use a sprung pin (pogo) connector, but it makes the most sense.

A lot better than that dumb "angel shot" - interesting idea, but totally pointless in practice.
A call button of some kind in the ladies that lights up something at the bar would be even better - you can grab something like this on amazon for 25 bucks.
You have been given good advice. I have slept in the same room as the patient, but in a recliner chair. In assisted living facilities, we call this a "sitter" arrangement.
There are Call Buttons from Amazon that can alert you. Mom, just presses the button.
I would also recommend a bedside commode which you can place next to her bed. This reduces the amount of walking that needs to be done at night. She gets up, goes and then lays back down.
My "survival treat" gift for new moms is a nice selection of good protein and granola bars, lansinoh lanolin cream (it's the go-to for chapping from nursing, but also great for frequently-washed hands and chapped lips), a caregiver pager (if she's doing this entirely alone maybe don't, but otherwise this is amazing for being able to wake/alert someone who currently isn't on baby duty if you're trapped under a sleeping baby or dealing with some kind of mess or challenge; also that way she can put her phone on DND and get some real sleep knowing the other person can buzz her if something urgent comes up), stack of dark-colored hand towels and washcloths (dark = don't worry about stains), and a bunch of pairs of really soft socks. I pack all this in a basket or rope bag with handles that someone can stick an arm through and haul from spot to spot and keep nearby wherever they are, along with their phone and lip balm and any other necessary/comfort items.
These Caregiver Transmitters usually work. They are very popular.
Wireless call button, receiver uses batteries, has multiple chimes and volume control, with a pretty loud "high" setting. I've used this with family and professionally, very reliable, I change the batteries every 4-6 months depending on how much the button is pressed each day/night. This link is for 2 buttons and 1 receiver, they also sell them with 2 and 2, and they have watch buttons if that's better for your supported person than a lanyard or tabletop button.
Personally, when helping a person who is likely to have a break in power, I like to stick one of those push button lights from the dollar store or Walmart on the wall by their bed and by their door, and in the bathroom.
Happy caring ❤️
Search “caregiver call button” or “caregiver pager”. There are a decent amount of products out there:

I did a few searches and found something on Amazon called the CallToU Wireless Caregiver Pager Call Button. Something like this could be exactly what you need. This model doesn't have a smartphone app but I bet if you dig further you can find a similar product that does.
Amazon has a number of different call lights as they are referred to in a skilled nursing facility. I have also seen Life Alerts and inhouse cameras installed so yu can keep an eye on your patients.
This might be something that you might use. They are very popular as long as you are close by.: https://www.amazon.com/CallToU-Caregiver-Transmitters-Receivers-Attention/dp/B077SYPD5K/ref=sr\_1\_2\_sspa?crid=2GQ5APT39T5HV&keywords=caregiver+call+button+for+elderly&qid=1639080088&sprefix=caregiver+call%2Caps%2C361&sr=8-2-spons...
Maybe this Tuya Wifi button could be used as a starting point :

I wonder if a simple piece of cord could be tied around the door knob ... long enough the he can get where he needs to be then pull the cord to at least semi-close the door. Or a cane or yardstick to gently push the door closed.
Sanitary hand wipe cloths can be put into his walker bag so he can clean his hands when he gets back to the bed.
I also wonder if part of his not closing the door is fear that if he needs help you won't hear him or won't come right away. In my house we got a pair of CallToU buttons that hang around the neck and buzz where every you put the receiver. The entire family seemed to relax after that because we all knew that at any time for any reason they could 'call me' for help.
an obscure website called "Amazon" sells them.
I would just get something separate from the system, like a wireless pager that you can tell the front desk workers to press whenever they ring someone up.
Well in that case amazon sells the old school Pager. Im not sure how the services are configured on them.
