美国采购需求：黑白超声波、彩色多普勒超声波、心电图、数字X光、病人监护仪

I'm looking to source additional capnography end replacement pieces for our medical facility. It's critical for us to maintain a steady supply, so I'd appreciate your guidance on the best way to order more of these parts. Are there specific specifications or quantities that you recommend for optimal inventory management? Also, I'd like to know if there's a designated model number for the connector that connects to the patient. Having this information will help ensure compatibility and streamline our ordering process. Thanks in advance for your assistance—I look forward to hearing from you soon!
