1. A device for assisting entry of a needle comprising
a probe comprising at least one array of n*m ultrasound electro-acoustical elements, wherein in the array of electro-acoustical elements comprises n*m electro-acoustical elements, wherein n∈[1,10] and m∈[2,210], for forming an ultrasound depth image,
a holder for the probe, the probe holder adapted to provide rotation of the probe over at least ±45°, wherein a bottom of the holder is higher than a bottom of the probe,
a fixator attached to both sides of the holder for maintaining the holder in a spatial position, and also adapted to provide translational repositioning of the holder and probe of at least 1 mm in at least one direction parallel to a bottom probe plane,
wherein the holder and fixator are configured to leave a space directly adjacent to the front side of the probe free for entry of the needle and for tactile control of a vein or shunt,
a display for providing an ultrasound image of the probe,
a controller, the controller being capable of addressing the electro-acoustical elements and receiving signals from the electro-acoustical elements, the controller in use providing input to the display,
an input for an electrical power source for providing power to at least one of the probe, controller and display, and
wherein at least one array of electro-acoustical elements is adapted to form an ultrasound image under an angle of 40-90° relative to the bottom plane of the probe,
wherein the probe can be removably attached to the probe holder,
wherein the fixator is adapted to provide translational repositioning of the holder and probe of at least 1 mm in at least one direction parallel to a bottom probe plane movement in any direction parallel to the bottom probe plane, and
wherein the space is larger than 1 cm in a direction perpendicular to the front side.
