Handheld Medical Devices

With economic development, people’s living standards improve, the increasing aging population, people are increasingly concerned about their health, whenever the disease comes, people expect to get effective treatment, medical devices plays a very important role. Medical devices is to help people from the disease to healthy essential ancillary products, is supposed to bring hope to people. Medical products through the semantics and semantic features emotional semantic interpretation, the product of subjective emotional expression and manifestation of the objective needs of ergonomics and serve fusion product design, in order to create more in line with the "people" physical and psychological needs products.Medical product is different from daily products, it is dedicated products, and it has its own characteristics. And constipation assistant instrument is a privacy device, need to convey humane care more and more. Products should ensure the normal use, meet the patient’s medical treatment and psychological needs of low resistance. Products must be made to adapt to the "human" way of the senses to understand and operate, requiring shape, color or texture of the design and experience a manner consistent with people’s habits, to make every product a switch, knob, button through the structure, texture, location, color, shape and other symbolic meaning "speak","tell" its own purpose and correct methods of operation. This paper analyzes the morphology typical medical symbols, color symbols, lead to products shall meet the symbolic semantic elements, and symbols conveyed material semantics toilet elaborated to help users and patients related to the human needs and according to the characteristics of the privacy of the constipation assistant instrument to help simulate the operation of toilet aid processes and usage scenarios. Establishment of hospitals, nursing homes, home three typical usage scenario models for three different scenarios "people" demand character and individuality, select different semantic symbols,10models were designed and carried out to products product structure innovation. Combination of product semantics and ergonomics, the medical equipment is not only need functional, but also should good enough, easy to accept and inexpensive, and based on different usage scenarios to find markets, customers, products tripartite equilibrium is a topic worthy of further.
