Before (改善前)

Medical device users are doctors and nurses, which can be male or female. Especially for female staff, if the edges of the parts such as the connector of the catheter that are frequently touched by the worker’s hand have an edge, they will feel pain in their hands when locking the connector, it will hinder the work. Also, in the case of locking mechanisms, if certain force to lock is necessary, if it is hard to lock for a woman, it will reduce the user’s satisfaction.

After (改善後)

In medical parts such as connectors, the parts that are directly grasped by hand are designed with rounded corners as much as possible, so that users can avoid hand injuries when grasping parts. Although adding a radius to the corner may slightly increase the initial mold cost, considering the actual user at the site, providing a radius at the corner improves satisfaction and leading to quality improvement. In addition, the hardness of the lock needs to be adjusted so that it can be easily tightened with the power of a woman.

POINT(要約)

The key to designing medical components is to create products that will satisfy the actual user on the site. The use of manufactured parts at medical sites varies from occupation such as doctors, nurses, and researchers, and may be male or female. Therefore, the point is to perform “human-friendly product design” that is accepted by many people.
