I may have screwed up.
There I said it straight out front.
Only I’m not quite ready to totally eat humble pie just yet, so I am sending a desperate shout-out for help.
A couple of days ago I posted this: Can you link these 2 things?
The picture on the right, as most people correctly identified, is an Xray of a right sided haemopneumothorax.
The picture on the left, which people were not so certain about, was of 3 ping-pong balls.
I sanctimoniously challenged nurses to make the connection ( but not to tell others if they had).
Some people had indicated that they knew exactly what the connection was. Many more have sent me emails asking, pleading and demanding me to let them know.
And here is the rub….I may have screwed up. There may not in fact be any connection whatsoever.
Or ……there may be some unintended connection that others have found.
The answer (or not):
Many years ago, underwater sealed drains (connected to chest tubes, you know…to drain haemopneumothoraxes) used to consist of 3 separate glass bottles connected by rubber tubing. Just like you always see in those diagrams when you are learning about underwater sealed drains.
We used these bottles when I started nursing. I remember emptying them in the pan room and washing them out.
I thought they had a ping-pong ball inside a wire cage just under hole in the lid, to act like a one-way valve and stop any fluid flowing from the collection bottle up into the suction tubing. I was sure of this.
I remember ping-pong balls!
I have since visited some hospitals in (so-called) underdeveloped countries and seen them still using the 3 bottle system on some of their wards.
I thought I saw ping-pong balls. Yup, they did.
Just call me boxhead:
Kelly actually woke me up early the next morning:
“Hey Ian, that post you just put up about the ping-pong balls…..you’ve got it wrong”.
“No”, I mumbled into my pillow, “they were in the underwater sealed drainage bottles. Pretty clever huh?”.
“No, boxhead….they were in the wall suction bottles. There were never ping-pong balls in the drainage bottles!”
I sat up: “Look Kelly, I am a senior nurse….I have been around the ward once or thrice. There were ping-pong balls.”
“No Ian, what you are, is an idiot. NO balls.”
When Kelly says no balls, she means….no balls.
Call for help:
So before I have to cook up a large serving of humble pie, I am asking, nay pleading, for help.
I have 2 questions:
- Is there anyone else out there who remembers 3-bottle UWSD systems with ping-pong balls?
- For those who indicated that you got the connections. If not the ping-pong UWSD answer, what exactly was the connection that you saw ( it is me that is super curious now)?
I remember ping-pong balls! Does that make me a boxhead?…… er….yup, feel free to answer that.
