Magic items that use spell slots?

[Temennigru]

I'm making an arcane caster that has access to the cleric healing domain. For that reason, I have very few spells known (I know 0 5th level spells, even though I can cast 4 per day).

For that reason, I'm looking for items that can use up spell slots to create varied effects.

I've found Periapt of the Sullen Sea (converts spell slots to freedom of movement) and Robe of Mysterious Conjuration (converts spell slots into summon monster spells)

Are there any other such items? (I'd be really happy if there were an item to convert them into cure X wounds spells)

Runestaves are your friend. They are all in the Magic Item Compendium.
