Device for measuring blood pressure

DETAILED DESCRIPTION The present invention provides a simple, reliable system for use in measuring blood pressure which is compact and inexpensive.
A vibrating pump powered by a special coil is adapted to be connected to the hand bulb of a cuff or armlet.
A foot-operated switch activates the pump which quickly and safely inflates the cuff.
An apparatus is provided in conjunction with an inflatable cuff of the type having a single passage for inflating and deflating the cuff, and a hand bulb with a check valve for inflating the cuff and blocking off blood flow in a patient's arm.
The apparatus comprises a vibrating pump including means to restrict air flow to one direction at all times.
A flexible conduit extends from the outlet of the pump and a means interchangeable with the check valve is connected to the end of the conduit remote from the pump so that the pump can inflate the cuff through the bulb.
It is an object, therefore, of the present invention to provide a simple portable device for use in measuring blood pressure.
Other objects and advantages will be in part apparent and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.
