Blood pressure indicator
First Claim
1. A device for indicating blood pressure, comprising a cuff adapted to be secured about a limb, said cuff including an inflatable bladder, means for inflating and deflating said bladder, and at least one pressure sensing switch secured to said cuff;
- said pressure sensing switch including plunger means resiliently biased to impinge on said bladder, and sound emitting means actuated by said plunger means for signalling a predetermined pressure exerted by said bladder on said plunger means and the limb.

Abstract
A blood pressure indicator adapted for self-examination includes a blood pressure arm cuff having an inflatable bladder, and a pair of pressure sensing switches impinging on the bladder and set to audibly or visually indicate the maximum systolic and diastolic pressure permissible. The bladder is inflatable by a flexible bulb connected thereto through a hose and a unidirectional flow valve which maintains inflation of the bladder. As air leaks out of the bladder, the patient notes when the pulse returns to the brachial artery, in relation to the indications given by the switches to ascertain whether the blood pressure falls within the permissible tolerances.
