Design of a Special Shaped Foam Dressing Based on Anatomy / 中国医疗器械杂志

As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent bacteria from invasion and infection. With a saturated absorption ratio of 1: 8 or higher, it can keep the wound clean and moisture by absorbing large amounts of wound inflammatory secretions and is almost completely permeable to oxygen and carbon dioxide. Assuring safety and effect meanwhile, it has better outcomes than common dressings in the same application settings.

Application research of protein test by using biuret reagent / 中国医疗器械杂志

<p><b>OBJECTIVE</b>To investigate the biuret reagent to detect proteins in the application, the impact of different test conditions for test results.</p><p><b>METHODS</b>The biuret method to select three different instruments, reagents, calibrators are arranged in combination to form 27 sets of detection systems, each detection system is a combination of 5 serum samples for testing, 5 measured values obtained, the selection process normality good a serum for the study to determine the mean value of all AST after culling outliers obtained in order to calculate the various detection systems use a combination of biuret reagent to detect proteins bias.</p><p><b>RESULTS</b>The use of different detection equipment to detect proteins biuret reagent bias, homogeneity of variance (P = 0.467), the difference was not statistically significant (F = 1.688, P = 0.421). different detection reagents using biuret reagent to detect proteins bias, homogeneity of variance (P = 0.574), a statistically significant difference (F = 5.784, P = 0.011). different calibrators use biuret reagent to detect proteins bias, homogeneity of variance (P = 0.467), the difference was statistically significant (F = 5.289, P = 0.000).</p><p><b>CONCLUSION</b>Biuret reagent in the detection of protein applications, impact detection reagents and calibrators will test result, during the test than when it is necessary to detect deviation detection reagents and calibrators due to be considered.</p>
