In addition to this, the addition of additional features to the shape of the mirror, its effectiveness and safety, as well as its effects. ●Please note that the information contained in this document was not specified, and the information regarding the combination of medical equipment and equipment under the circumstances of the new equipment was examined. In addition, there may be a change in the identification, a change in the accompanying text, a change in the name of the product, etc., a change in the name of the product, etc., due to the fact that there is no effect on the effectiveness and safety of the product, and there is no effect on the performance of this request. Handwritten. |
Product or technological changes (excluding raw materials)
| Change in working principle? | ●Is it right or wrong? Is there a change in the operating model or operating mechanism (principle) of the existing equipment? Is there a change in the working principle that has a large influence on the mechanical ability? In addition to this, there are changes in the mechanical control system when considering the demand, such as changes in the control system of the electric machine and the mechanical control system. ●For example, the difference in the fixed flow and the dynamic flow in terms of artificial new creation, the difference in the internal view light source, the change in the direct light method that leads to the light source, etc. |
Change for the purpose of using the effect? | ●Review of "Intended Use, Functionality and Effects" during the limited review, review of changes, and intended use (classification of use for comprehensive eyeglasses, middle-sized eyeglasses, peripheral use to central use, etc.)? ●For example, there are various types of changes in the shape of the eyeglasses, such as the use of diffused light. |
Warnings, contraindications or precautions? | ●Warnings/Contraindications and Precautions are usually not included in this page, but please note that this is not required in the PMDA safety section. |
Changes in the renewal dynamic category? | ● Changes in mechanical power sources or types of mechanical power output. For example, when an alternating current electric current changes to an internal electric source, and when the current energy is absorbed into the body, an electric current changes from a radiating line to an ultrasonic wave. |
Change in performance or scale? | ●Details on the equipment's intended performance or function will change when the equipment is developed. Significant changes in the comprehensive equipment usage environment, etc. For example, additional functionalities in medical electrical equipment, increased curvature strength of artificial tubes, increased strength of high tube tubes, increased ability to withstand pressure of tubes, improved cleanliness of dialysis machines, The characteristics of high MRI resistance may vary. |
Ergonomic changes at the patient/user interface? | ●Is there a change in the interface between the patient and the user? ●For example, various types of warning sounds, light alarms, control panel distribution, face-to-face information presentation methods, etc. |
Change in size/shape? | ●Mechanical physical size or shape change? Dimensions include mechanical length, width, thickness or diameter, and the location of equipment and components. |
