J MED ENG TECHNOL , 1985, vol. 9, n° 1, p. 14-17 Doc n°: 21471 Localisation : Documentation IRR Descripteurs : AE1 - ETUDES GENERALITES - MOELLE, HG -TECHNOLOGIE DE LA SANTE An instrument which locates blood vessels by means of Doppler ultrasound and directs a needle at the located vessel has been developed. The feature of this instrument is that the needle does not pass down the ultrasonic beam as in other techniques that have been tried. Two transducers, mounted on sliding bars, are used to pin-point the vessel. The needle is then guided towards the intersection point of the two beams. Both the angle of entry and the transducers are kept well away from the needle and at an optimum angle to the skin; Langue : ANGLAIS Identifiant basis : 1985002343 |
