In addition to the two design points mentioned above, the tactile design of handheld medical devices is also a very important aspect. The tactile design is mainly to allow the operator to clearly feel that he or she is operating a medical device, and at the same time, it is more obvious in the sense, to avoid unnecessary influence caused by too much or too little force.
Haptic design has always been an important aspect of the design of handheld medical devices, often breaking through as a design bottleneck. For example, membrane keys have become the main type of lightweight haptic controllers. The functions on the pulse oximeter membrane buttons are not only for the on / off control function used in power supply, but also for other on / off switching functions: it also has step control function. Taking the pulse oximeter plus as an example, affected by the structure and function of the pulse oximeter device itself, the design of the membrane buttons should meet the operating rules of a single handhold, the control keys should be able to be operated with a single finger, and the control key arrangement should not be caused easily Misoperation occurred. From the above expressions, haptic design will directly affect the daily use, repair, optimization and other tasks of handheld medical devices, and will have a greater impact on users.
In future work, haptic design must be more humane. On the one hand, it improves the sensitivity of haptics, and on the other hand, it increases the prohibition function of erroneous operations. Problems that occur should be stopped. Conclusion This study analyzes the key points of the design of handheld medical devices. As far as the existing handheld medical devices are concerned, they have largely met the needs of medical staff and patients. The emergence of some handheld medical devices appears to be somewhat inadequate in performance, and further design is needed in the future.
In summary, there are many key points in the design of handheld medical devices. In the design work, not only must meet the specifications of the design points, but also increase the value of handheld medical devices, and provide more medical staff and patients help.
