What is DHF short for?
Dengue hemorrhagic fever (DHF) is defined as a severe form of dengue characterized by bleeding, hemoconcentration, and plasma leakage, often following typical dengue symptoms. It is caused by dengue viruses transmitted by mosquitoes, primarily affecting humans in endemic regions. The definition of DHF consists of 4 clinical criteria: fever, a hemorrhagic tendency (spontaneous bleeding or a positive tourniquet test result), thrombocytopenia (platelet count, ≤100000 cells/mm3), and plasma leakage as shown by pleural effusion, ascites, or ≥20% hemoconcentration.
What is the difference between DHF and DHR?
Just as the DHF is the archive of everything done for product design, the DHR is the archive of everything done for product manufacturing. The DHR therefore must include: Date of manufacture and quantity. Production and testing records (demonstrating compliance with the DMR). Each manufacturer shall maintain device history records (DHRs). Each manufacturer shall establish and maintain procedures to ensure that DHR’s for each batch, lot, or unit are maintained to demonstrate that the device is manufactured in accordance with the DMR and the requirements of this part.Definition. The FDA mandates that medical device companies produce a device history record (DHR) that contains all documentation related to manufacturing and tracking the device, and demonstrates that the device was manufactured according to the information in the device master record.
What’s the difference between Maxxis DHF and DHR?
While there are a few size differences, the main difference between the two tires comes down to the center tread. The Maxxis DHF has a bit of a taller and skinnier siped knob, with an alternating solid knob. It’s also good to note that the center siping on the DHF runs in the direction of the circumference of the tire. Maxxis tires contain barcodes and date stamps which allow for tracking of production runs on the inside of the casing. Tires with barcodes and/or date stamps that have been defaced, modified or removed are likely “grey market” products and are not covered by the Limited Warranty.While Maxxis tyres are considered a premium brand, they are known for offering exceptional value for money compared to other premium tyre options.
What does DHF stand for?
DHF is the design history file. As you go through the design and development process for your medical device, the documentation that you create will be contained in your design history file, commonly abbreviated as DHF. Design history files (DHFs) and device mater records (DMRs) are critical to demonstrate compliance throughout the entire product lifecycle.
What is DHF vs DMR vs DHR?
The Design History File (DHF), Device Master Record (DMR), and Device History Record (DHR) are key regulatory documents in the lifecycle of medical devices, referenced under FDA 21 CFR Part 820. What is an eDHR? Manufacturers must record produced products in medical devices and diagnostics (MD&D) manufacturing. This is called the ‘device history record’ (DHR). Other terms include the batch record or lot history record.
