ULTRASOUND PROBE WIPES




  • Cross contamination is a serious phenomenon in the case of ultrasound sonography.
  • In may cases the ultrasound machines and probes may act as both source and vectors of pathogen, because they come into direct contact with patients and practitioners during scanning procedure.
  • So it is necessary to keep them clean and sterilized
  • Ultrasound wipes are one of the quick and easily usable disinfectant.

The main advantages of disinfecting wipe are :

  1. Easy to use
  2. Do not causing any damage to ultrasound system

ULTRASOUND LEAKAGE TESTER


  • In the case of ultrasound equipment , electrical safety is the primary consideration for patient's safety.
  • The leakage testers are specially designed to test the electrical safety to all type of diagnostic ultrasound transducers.
  • This equipment measures the capacitive leakage current and the integrity of the outer insulation barrier of the transducer.
  • The available leakage testers are :

HAND HELD FORCE CONTROLLED ULTRASOUND PROBE


  • Currently ultrasound probe acquisition states are manually controlled by ultrasound sonographer. ome times it can be leads to imaging variations, because he acquisition state at any given time is not repeatable at a later time.
  • The hand held force controlled system is the solution for such problems.
  • The controlling the acuisition state through real time feedback leads to more consistent ultrasound image and safer  medical procedures.
  • It is introduced by Mathew Gilbertson, Brian Anthony and Shih-Yu-Sun of MIT

WORKING
  • The device consist of an ultrasound probe mounted to a backlash free ball screw actuator and driven by a compact servo motor, maintains a prescribed contact force between the ultrasound probe and the patient’s body.
  • The control system consist of force controller and position controller always maintain the actuator centered within the range of motion ,hence prevent the repeated making and breaking of probe-patient contact.

ADVANTAGES
  • Maintains a constant contact force between the ultrasound probe and patient’s body.
  • Provides controlled acquisition state ,hence improves imaging quality.
  • Easier to control & more user friendly
  • Provides the user with visual and audio feedback, informing them the position, orientation, and contact force of the device.
  • Provides push buttons on the device itself, enabling the user to initiate events (e.g., data recording, zeroing the angle) without needing to interact with a computer; hence users can focus on the device rather than the computer screen.
  • Fits comfortably in an ultrasound technician’s hand
