| 摘要 |
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to means with increased echogenicity for obtaining ultrasonic images. Device contains intervention device, image of which must be received by means of ultrasound, and echogenic polymer sleeve, located near intervention device and containing biocompatible deformable membrane, which covers at least part of intervention device. Topography of echogenic polymer sleeve is adjustable by means of its axial compression, which changes length of echogenic polymer sleeve relative to intervention device and forms riffles on biocompatible deformable membrane, riffles are visible for ultrasound and increase echogenicity of intervention device. Method of increasing echogenicity includes placement of biocompatible membrane near intervention device and compression of sleeve along axis to change its length and form riffles on biocompatible deformable membrane. In second version of device implementation mechanical deformation of echogenic polymer sleeve changes its thickness and forms riffles on biocompatible deformable membrane.EFFECT: application of invention improves visibility of objects in ultrasound.16 cl, 4 dwg |
