Device regulations

FDA s medical device regulations relating to adulteration and misbranding generally apply to devices intended for use on animals. These devices, however, are exempt from the 510(k) and PMA requirements. FDA has viewed animal grooming products as being outside of its purview. 

A regulator is a compact device that maintains the process variable at a specific value in spite of disturbances in load flow. It combines the functions of the measurement sensor, controher, and final control element into one self-contained device. Regulators are available to control pressure, differential pressure, temperature, flow, hquid level, and other basic process variables. They are used to control the differential across a filter press, heat exchanger, or orifice plate. Regulators are used for monitoring pressure variables for redundancy, flow check, and liquid surge relief. 

The fan of the air curtain is to be provided with a device regulating the supply airflow, for example, by frequency transformer, multispeed motor, etc. The supply airflow is to change according to the dependence - Ap , which enables, in particular, provision of the necessary efficiency for version a. 

The range of devices regulated under the general medical device directive, 93/42/EEC, can vary from the simple devices that pose little or no risk to patient or user health to those that are life-critical. It is neither economically feasible, nor justifiable in practice. 

Class I devices are considered low-risk devices and represent approximately 50% of all devices regulated by the FDA. A device is assigned to Class I if general controls are sufficient to provide reasonable assurance as to the safety and effectiveness of the device. Devices that are not life-supporting or life-sustaining, or are for a use which is... 

FDA device regulation is focused on the device and the device manufacturer. CLIA, on the other hand, focuses on laboratory quality, including the quality of the laboratory test results provided by the devices used, whether developed in-house or as a test kit in commercial distribution to multiple laboratories. The programs differ substantially in approaches and in data requirements. FDA requires unique submissions for each test under its purview, evaluates both performance and labeling, and requires demonstration of analytical validity and clinical validity as appropriate. CLIA inspects laboratories using a system approach based on key probes of the operating system. CLIA requires a demonstration of analytical performance and quality control but does not require a showing of either clinical validity or clinical utility.

In the United States GMP regulations [7] issues related to laboratory controls are covered in Subpart I, which consists of regulations 211.160,211.165,211.166,211.167, 211.170, 211.173, and 211.176. The contents of Subpart I is presented in Table 24. Regulation 211.160 states the requirements for the establishment of laboratory controls such as specifications, standards, sampling plans, and test procedures. Furthermore, it covers the requirements stated for the calibration of instruments, apparatus, gauges, and recording devices. Regulation 211.165 states the require-... 

Revision of medical device regulations has occurred in other countries, including Canada and the United States, because of the European experience. In 1998, Canada changed its device regulations to include a risk-based classification system and 11 principles of safety and effectiveness, which were patterned after the essential requirements of the European MDD (22).

Each manufacturer shall establish and maintain the requirements, including quality requirements, that must be met by suppliers, contractors, and consultants. ... 

Trends Over Time The FDA Modernization Act, Team Biologies, New Medical Device Regulations, and Quality Systems Inspection (QSI)... 

The new medical device regulations were codified in 1996, significantly altering the way in which medical device manufacturers were inspected by the FDA. The quality systems inspection technique (QSIT) was launched as part of the new strategy for inspecting the device industry. This inspection technique allowed FDA to move closer to global harmonization guidelines...

Most cylinders used to store gases have safety devices regulating the internal gas pressure. The most common of these is a pressure relief valve. If the pressure inside the cylinder increases to a dangerous level, a spring allows the valve to open and release excess gas until the internal pressure returns to a safe level. Some pressure relief valves will close once excess gas is released. These valves are relatively expensive compared to non-reclosing valves. Non-reclosing valves are found on common household products such as aerosol hairsprays.

Molecular Devices with Directional Functionality-Supermolecules That Transmit Signals in a Desired Direction The ability to direct the flow of information in a desired direction is crucial to molecular device development. Controlled organization of functional molecifles, mainly using the LB method, was used to prepare molecular devices regulating electron or energy flow.
