UltraScope Stethoscope Polka Dots 133 – Black with Hot Pink. Auscultation with the UltraScope Stethoscope is very easy. The UltraScope’s unique, rounded, single-sided acrylic head offers efficiency in auscultation. Sounds are easily monitored by alternating pressure between auscultation sites. Use very light pressure for low frequency responses, firmer pressure for higher frequency responses. Too much pressure will block all sound. The UltraScope excels in medically challenging situations. It is as good as any cardiology scope on the market. The UltraScope works in excessively noisy environments, through hair or bandages. Adult size head. Polka Dot Design, Black with Hot Pink Dots (133). Your choice of colour tubing.
