Benefits of Using COVID-19 Protective Shields in Hospitals

How Do Protective Shields Contribute to Infection Control?

Protective shields serve as an essential barrier in hospitals, effectively blocking the direct path of airborne particles that can carry viruses, including COVID-19. By interrupting the trajectory of infectious droplets, these shields substantially reduce the risk of transmission among patients, visitors, and healthcare staff. Their use is particularly crucial in close-contact scenarios where social distancing is not feasible.

Impact on Patient and Staff Safety During the Pandemic

The deployment of COVID-19 protective shields has had a profound impact on enhancing safety and confidence within healthcare environments:

• For Patients: Shields provide a sense of security, knowing that measures are in place to protect their health during hospital visits or stays.
• For Healthcare Workers: Shields add an extra layer of protection, complementing other personal protective equipment (PPE), thus reducing stress and the risk of infection. This protection is vital not only for their health but also for maintaining staffing levels critical to hospital operation.

Design and Customization of Hygiene Screens

Design Considerations for Enhancing Protective Efficiency

When designing hygiene screens, several factors must be considered to optimize their protective efficacy:

• Coverage Area: Ensuring the screen covers enough space to effectively shield the breathing zones of standing or seated individuals.
• Ergonomics: Designing screens that accommodate various interactions, such as passing documents or items safely, without compromising the barrier's integrity.
• Visibility: Maintaining clear visibility for communication and patient monitoring without distortion.

Customization Options to Fit Various Hospital Areas

Hygiene screens can be customized to meet the specific needs of different areas within a hospital:

• Reception Desks: Screens may include a pass-through window or be shaped to fit desk contours.
• Patient Rooms: Freestanding, mobile screens can be used to move easily and adjust placements as patient needs change.
• Clinical Areas: Tailored designs for areas like pharmacies or labs where functionality might include resistance to chemicals or frequent interactions.

Maintenance and Cleaning Protocols

Maintenance Requirements for Longevity and Effectiveness

Maintaining hygiene screens involves regular checks and upkeep:

• Structural Integrity: Regular inspections to ensure all components remain securely attached and the screen’s stability is not compromised.
• Wear and Tear: Monitoring for scratches or other damage that might impair visibility or functionality.

Recommended Cleaning Procedures to Prevent COVID-19 Spread

Effective cleaning protocols are critical to ensure hygiene screens continue to act as a barrier to COVID-19:
