Does the Manufacturer Really Manufacture?

For a primary-care buyer the key question is not how large the factory is, but whether this model is still in production and whether spare parts will still be available.

1. Check the production licence and its scope. The certificate number, issuing authority, scope and expiry date must all be present before it counts. Ours is Yue Shi Yao Jian Xie Sheng Chan Xu 20132454, scope Class II 06 Medical Imaging Devices, valid until 2028-05-07.

2. Check whether the model is on the registration certificate. Primary-care buyers usually purchase in the lower price band, where models change quickly and it is common for a quoted model to be missing from the certificate. Comparing the model against the "model and specification" column on the certificate is the simplest way to catch this.

3. Check the supply commitment for parts and consumables. Whether probes, batteries and charging pads can still be bought three years from now decides how long the system stays usable. Ask for a minimum spare-parts supply period after end of production to be written into the contract.

Primary-care equipment is used for five to eight years, so choosing a manufacturer is really choosing a supplier who will stay with you for that period. Scale is a bonus; continued supply is the minimum standard.
