Definitions

  • the invention relates to an ultrasound applicator according to the features of the preamble of claim 1.
  • the organs of interest for ultrasound scanning e.g. B. kidneys, thyroid, liver, heart or in women also the female breast, at quite different depths. This means that these organs do not always have the optimal position with regard to the focus of the scanning ultrasound lobe. In principle, this applies to all ultrasound applicators with direct coupling to the body surface only via a coupling gel.
  • Such applicators are e.g. B. normal compound scanners, mechanical sector scanners and in particular also ultrasound arrays in any training, as z. B. in the article "Real-time sonography with the linear array scanner Multison 400 by V. Zurinski and R. Haerten in the magazine" E-lectromedica 46 (1978) No. 4, on pages 141 to 148 are described .
  • ultrasound applicators are also known in which the vibrating elements are coupled to the body via a water flow path.
  • the device known from the brochure «VIDO S ON 735 SM Ultrasound Real-Time Tomograph with water inlet section DATA E 441 from 1979 without special measures does not allow the distance of the vibrating elements from the body surface within the water inlet section to be varied
  • ultrasound is possible -Array of DE-PS 2529112 such a change in distance possible.
  • the latter ultrasound applicator is specifically a sector scanner that scans line by line due to the curved design of the ultrasound array in a sector.
  • a displacement device is provided which enables a change in the distance between the curved array and the coupling point on the body within the water flow path.
  • the object of the invention is to design an ultrasound applicator according to the preamble of claim 1 in such a way that it can be easily and quickly adjusted to different depth sensing in the sense of the above explanations.
  • the invention makes it possible for the ultrasound head to be preceded by a liquid bag (with, for example, water or an oil which conducts the ultrasound well or the like), which elastically changes the distance between sound-generating vibrating elements of the ultrasound head and the body surface, which in turn changes the scanning depth becomes.
  • a liquid bag with, for example, water or an oil which conducts the ultrasound well or the like
  • the fluid sack is easy to assemble and can be dismantled just as quickly if you scan from areas close to the skin (e.g. thyroid, kidneys, female breast) to scan deeper organs (e.g. liver, intestine or even heart) should be switched. In the latter case, direct coupling is then carried out again with the omission of the liquid bag.
  • the dimensions of the liquid sack can be changed by inflating it to different extents, so that this enables a further depth variation when using such a sack.
  • the ultrasound array is designated as 1 as an ultrasound applicator.
  • the ultrasound array has a connection 2 for an electrical signal and power supply cable.
  • the actual ultrasound head is labeled 2.
  • a liquid bag 4 is connected upstream of the ultrasound head 2 with the transducer elements 3.
  • the latter consists of a sleeve 5 made of stretchable material, e.g. B. natural rubber, which is filled with a liquid that conducts ultrasound well, in particular water or a corresponding oil. In the present case, water is used as the filling material, which is also specially prepared against fungal attack by a special agent.
  • the liquid bag 4 is clamped to the ultrasound head 2 of the array 1 by means of a simple clamping part 7, which has the shape shown in FIG.
  • the clamping part from z. B. resilient plastic material, e.g. B.
  • the water bag itself can have different dimensions corresponding to different application conditions. With one and the same array, the dimensions of the liquid sack can be changed within certain limits by means of water inflation of different strengths, so that this enables a further depth variation when using such a sack.
  • the rail 12 is arranged in each case inside the liquid sack 4, as is the case for. B. is indicated in Figures 1 and 2.
  • the fluid bag 4 connected upstream of the transducer elements 3 of the transducer serves as an elastic spacer; depending on its dimensions, it varies the depth at which the focus of the scanning lobe of the ultrasound head 2 comes to rest.
  • organs in the area close to the skin can be scanned. If switching to lower organs is to be carried out on scanning, the sack 4 is removed again and the ultrasound head 2 with the transducer elements 3 is coupled directly (only via the coupling gel) to the body surface.
