Design and application of handle of freezer for epidemic prevention materials
Against the background of COVID-19 epidemic situation, various epidemic prevention measures emerge one after another. Among them, the freezer, as an important tool for storing vaccines and medical supplies, plays an important role in the epidemic. In order to ensure the safety of workers and avoid cross-infection, the handle of the freezer has also been specially designed to meet the needs of epidemic prevention.
First, the choice of handle material
1. The material requires strong antibacterial property. In order to prevent the virus from adhering to the surface of the handle, antibacterial materials are selected to make the handle, which reduces the possibility of bacterial reproduction.
2. Use environmentally friendly and harmless materials. Considering frequent human contact, it is necessary to ensure that the handle does not contain harmful substances, such as heavy metals and other pollutants.
3. High corrosion resistance. Because disinfectant will cause certain corrosion to metals, stainless steel or plastic products with good corrosion resistance are selected.
4. Good anti-slip and sweat-proof function. In order to facilitate the user's grip stability and prevent slippage caused by sweat on the palm, the anti-slip grain design can be added or the soft-felt silicone kit can be wrapped in the outer layer.
Second, ergonomic considerations of handle modeling
1. Make sure it is easy to grab. According to the principle of ergonomics, the best shape and size are determined, so that users can easily grasp the handle to complete the opening action;
2. Reduce the demand for use. Reduce the required applied force by optimizing the structural layout and reducing the weight;
3. Reduce fatigue. Repeating the same task for a long time is easy to cause musculoskeletal problems, so the pressure point can be relieved by adjusting the angle curvature and other methods.
4. Provide a variety of style options. Provide diversified options according to the needs of different groups of people (for example, more cute and interesting cartoon patterns can be designed for children and patients).
Third, the handle cleaning and maintenance suggestions
Because it is often touched, the handle can easily become one of the vectors of virus transmission. In order to avoid this situation, it is necessary to thoroughly clean and disinfect the handle regularly:
1. Wipe regularly every day. Wipe the surface gently with wet tissue paper made of chlorine-containing bleach solution or other effective bactericidal ingredients;
2. Regular deep cleaning. Carefully scrub with hot water and soap powder every once in a while to remove stubborn stains and air dry and store them for later use;
3. Pay attention to drying. Ensure that the handle is in a well-ventilated environment, and try to avoid water retention to avoid breeding microorganisms such as mold;
4. Add protective gear. If conditions permit, a layer of physical isolation device such as transparent acrylic board can be added outside the handle to isolate direct contact.
In short, with the development of epidemic prevention and control, various new products and services will emerge as the times require. This is especially true for epidemic prevention materials-only by continuous innovation and improvement can we better serve the health and safety of the public!
