EDAN SE-300 SE-300B ECG bottom case ECG machine parts plastic material used in good working

► Brief Introduction

The EDAN SE-300 SE-300B ECG bottom case is made of a hard plastic material, providing sufficient strength and rigidity to withstand daily use, such as placement, transportation, and even minor bumps, effectively protecting internal components from physical damage. The bottom case not only insulates the user and patient from electric shock but may also contain a metal shielding layer or coating to effectively isolate external electromagnetic interference, ensuring weak ECG signal acquisition is not affected while also preventing the leakage of electromagnetic waves generated by the device itself. Although second-hand, it appears to be in excellent condition.

► Core Functions of the Bottom Case

1. Structural Framework and Physical Protection
The bottom case and top cover together form the main body of the ECG machine, housing the delicate circuit boards, processor, battery, and printing module.

2. Heat Management
When the ECG machine is in operation for extended periods, the internal electronic components generate heat. The EDAN SE-300 series bottom case is typically designed with strategically placed ventilation grilles. These grilles are not randomly placed; they work in conjunction with the internal structure to create effective airflow channels, dissipating heat from core components (such as the power module and main control chip), ensuring stable operation at optimal temperatures and extending the device's lifespan.

3. Stand Hinges: The bottom features hinge holes for the adjustable stand, ensuring the stand can securely support the entire device and facilitate viewing the screen from various angles.

4. Anti-slip Feet: Rubber anti-slip feet adhered to the bottom prevent the device from sliding on smooth surfaces, scratching the surface, and providing some shock absorption.

5. Screw posts and latches: Precision-designed internal screw posts and latches ensure a tight and secure fit between the bottom case and top cover, forming a complete seal and preventing dust and liquid intrusion.

►When does the bottom case need attention or replacement?

1. Device dropped or impacted: Obvious cracks or damage compromise the device's overall seal and safety and require immediate replacement.

2. Broken screw posts: Rough disassembly and assembly may break the internal screw posts, resulting in a loose connection, unusual noises, or potential safety issues.

3. Damaged battery door: A broken door latch or damaged hinge can cause poor battery contact or device power failure.

4. Severe cosmetic wear: In medical environments with stringent infection control requirements, if the housing surface has irremovable stains or severe scratches, replacement may be necessary for both aesthetic and infection control reasons.
