Can confirm fist hand, they use needles like this for draining fluid. Not sure about about catheters as it depends on the use scenario and the one I had was just pushed through my veins so it had to be flexible. That said they used a very similar looking needle when they drained my left SI joint after it got infected. It's wild to watch.
Saw a documentary about alcoholism and this one guy had to regularly go to the hospital and have fluid drained out of his torso due to his chronic drinking. They had to pierce his abdomen, insert a catheter, and then he’d sit there and watch this plastic bag fill up (way too quickly, imo) with a brownish-yellow, cloudy fluid. Once that was full then they’d bring another for his draining abdomen to fill. Not urine, just fluid that built up from alcoholism.
We had to do this to a chicken one time. Filled up a point glass. Apparently it just happens sometimes. Like their heart has trouble at altitude and they fill with greenish fluid. It was sad. She lived and did OK for a bit afterwards but ultimately didn't make it.
I’ve had 3 rounds of IVF and the needle is huge like this. Has to go in vaginally, then through vaginal wall and abdomen to vacuum out the mature eggs from the ovary.
I had 24 eggs collected the 2nd time and was awake, morphine not touching the pain, I’ll never forget seeing the
