Discussion on the design and importance of the handle of blood storage freezer
In the blood bank of a hospital, you can often see a special type of refrigerator-blood storage freezer. This kind of refrigerator is used to preserve and protect the precious blood resources of human body. As the most common part of daily use, the handle design of blood storage freezer is also very important.
First, the importance of handle
For the user, the handle of the blood storage freezer is the direct contact part. A suitable handle can provide users with a better experience; On the contrary, it may bring a series of problems. For example, if the handle is designed unreasonably or the material is not durable, it may break during frequent opening, which will affect the normal use of the refrigerator. Therefore, it is particularly important to scientifically and reasonably select materials and design the structure of the handle.
Second, the selection of handle materials
1. Stainless steel
Stainless steel has the characteristics of strong corrosion resistance, high hardness and easy cleaning, and is one of the ideal handle materials. However, due to its smooth surface, it may slip by hand, so it is necessary to take anti-skid measures to improve the grip comfort.
2. Aluminum alloy
Aluminum alloy is not only light and high strength, but also has good corrosion resistance. It is widely used in various equipment, which can effectively reduce the workload of staff.
3. ABS plastics
ABS plastic is tough and wear-resistant, good in insulation and low in cost, which is suitable for mass production. However, due to its poor thermal conductivity, it is prone to brittle fracture and deformation in extremely cold environment, so it is not recommended to use this material to make the handle of blood storage freezer in cold environment.
Three, handle shape and size considerations
In order to ensure that the operator can easily open the blood storage cabinet door and take out the required items, the handle must have a certain width and length ratio to ensure a good grip. In addition, the following points need to be considered:
1. Ergonomics principle: Customize the design according to the hand size and strength difference of different people;
2. Convenient maintenance: easy to disassemble and replace to facilitate regular inspection and maintenance;
3. Aesthetics: An elegant appearance can increase users' satisfaction.
IV. Conclusion
Although it looks simple and ordinary, in fact, every detail is full of wisdom and ingenuity. Only after careful design can users get a good experience and ensure the normal operation of medical equipment. Therefore, when we pay attention to the performance index of the whole machine, we should not ignore the seemingly insignificant but vital small accessories like the handle.
