GB/T 16886.2 Biological evaluation of medical devices Part 2.Animal welfare requirements3 Terms and definitionsThe terms and definitions defined in GB/T 16886.2 apply to this document.4 Animal selectionIt is advisable to use healthy, non-pregnant, adult miniature pigs with an initial weight of 25kg to 30kg, regardless of gender. The suitability of the experiment should be explained. The experimental animals should be of qualified quality and their skin should be intact. The number of animals should be selected in combination with the purpose of the experiment, design type, evaluation index and The accuracy of the evaluation method and other statistical factors should be considered comprehensively to determine the result. It is generally recommended that the sample size of the test samples and control samples that complete the effective test at the final observation point should be no less than 10 each, so the number of animals There should be no less than 4.5 Main instruments and equipmentCommonly used surgical instruments, animal anesthesia monitoring equipment, pathological examination equipment, etc.6 Surgical Procedure6.1 Selection of control samples It is advisable to select similar domestically marketed products with similar materials, structural design, and working principles as control samples. For products, reasonable reasons and evidence for the selection of control samples should be provided. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YY/T 1754.4-2024_English be delivered?Answer: Upon your order, we will start to translate YY/T 1754.4-2024_English as soon as possible, and keep you informed of the progress.
