墨西哥采购需求：黑白超声、彩色多普勒超声、心电图、数字X光、病人监护仪

I'm looking to source rectal and convex probes for our upcoming product line. Can you provide details on the available options, including specifications, materials used, and any compliance with relevant safety standards? Additionally, please let me know about the MOQ, lead times, and pricing tiers. If you have any catalog or product sheets, that would be helpful as well. Looking forward to your prompt response so we can proceed with this potential order.
