Also, ensure your partner is fully aware of the issues, and explore possible bindings carefully. Since you have ;ostly got problems on your right side, then you are nicely open to some asymetric bondage, which the Japanase favour. Binding your right arm so that it is in no way stretched, but so that you cannot move it, and bound tight, is still binding! And it sounds like the elbow is OK

And of course ensure that there are scissors/sharp knife available for immediate use, and fast release mechanisms for any suspensions.
