Background

Medical instruments refer to instruments, devices, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. The effects are obtained mainly by physical means, not by pharmacological, immunological or metabolic means, or they are involved but only as an aid. For the purpose of diagnosis, prevention, monitoring, treatment, or amelioration of a disease; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; by examining a sample from a human body, information is provided for medical or diagnostic purposes. The medical appliance industry relates to a plurality of industries such as medicine, machinery, electronics, plastics and the like, and is a high-technology industry with multidisciplinary intersection, knowledge concentration and fund concentration. The basic characteristic of the medical equipment with high and new technology is digitalization and computerization, is the multidisciplinary and cross-field modern high-technology crystal, and has high technical content and high profit, so the equipment is a high-level system for mutual competition of all scientific and technological countries and international large-scale companies, and has higher intervention threshold. Even in the sub-industries with low overall gross profit rate and low investment of the industry, products with high technical content are continuously produced, and some enterprises with high profit capacity are bred from the products. The general industry trend is therefore high investment and high revenue. The medical imaging equipment is an indispensable component of medical equipment in hospitals and is also an important embodiment of the comprehensive strength of the hospitals.
