The National Medical Products Administration (NMPA) in China regulates a wide range of medical devices, which are categorized into three classes based on their risk levels. Here’s a brief overview of the types of devices accepted by the NMPA:

1. **Class I (Low-Risk Devices)**: 

   - General medical devices that pose minimal risk. 

   - Examples include bandages, surgical gloves, and simple tongue depressors.

   - These devices typically do not require pre-market approval and are subject to registration.

2. **Class II (Medium-Risk Devices)**: 

   - Devices that have a higher risk than Class I and require more stringent regulatory controls.

   - Examples include infusion pumps, patient monitors, and certain diagnostic imaging equipment.

   - These devices require a registration application and must demonstrate safety and effectiveness.

3. **Class III (High-Risk Devices)**: 

   - Devices that pose the highest risk to patients and/or users.

   - Examples include implantable devices (like pacemakers), life-supporting devices, and advanced surgical tools.

   - These require extensive clinical trials to validate their safety and effectiveness and undergo a rigorous approval process.

In addition to these categories, the NMPA also accepts a variety of medical devices, including:

- **In vitro diagnostic (IVD) devices**: Tests conducted outside the body to diagnose diseases.

- **Combination products**: Devices that combine drugs and biological products.

- **Software-based medical devices**: Such as mobile health applications and software used in medical imaging.
