Episode 5 of After Trek (goes along with ep. 6, "Lethe") had a short segment on how they made sickbay for Discovery. The segment had several shots of the various medical props. It also mentioned that they used found items as the basis for most of the props. The mentioned soap dispensers and salt shakers (in honor of TOS).
I was watching on my TV, so I didn't grab any screenshots, but the episode is available on CBS-AA and these types of clips typically get posted to CBS's YouTube channel after a few days.
