Abstract

The invention provides a multifunctional oral cavity material testing machine. In an existing oral cavity material evaluation test, a test device has a single function, and each device can only test single performance of a single material; traceability is difficult, the existing test device is mostly designed temporarily, there is no corresponding design specification, there is no verification orcalibration specification, and a measurement result is difficult to trace; and an subjective influence is difficult to avoid, the existing test device is mostly the simple device which requires manualoperation, sometimes, the device needs to be used together with displacement measuring equipment, timing equipment and the like, and the influence of a human subjective factor is difficult to avoid.The testing machine can be widely used in the performance evaluation field of different oral cavity medical devices.

Description

technical field [0001] The invention relates to a testing machine for oral cavity materials, in particular to a multifunctional testing machine for oral cavity materials. Background technique [0002] In my country and most other countries in the world, oral materials are managed as medical devices. In order to ensure the safety of the people using devices, according to the regulations of the State Food and Drug Administration, medical device manufacturers must monitor the medical devices they produce. Registration testing and daily testing. Due to the variety of oral materials and different performance requirements, a variety of devices are required to complete the detection work. [0003] Although the detection devices currently used can meet the basic detection work needs, there are still many problems: [0004] First, single function: each device can only test a single performance of a single material. Taking water-based cement as an example, the properties of the mate...
