ABSTRACT:
A weight and pressure measuring device, comprising a fluid filled cushion pad of limited volume, connected to a pressure indicator to measure the pressure produced during pressure loading. Such a measuring device requires little space, is lightweight, and can easily be transported and used. A blood pressure and weight measuring device has an inflatable sleeve which is connected through a tube connection, with a pump device and a pressure measuring device. In order to measure blood pressure as well as weight, by means of such a measuring device, a second inflatable device, with a limited volume, is connected with the pressure measuring device and the pump device. The device measures the pressure produced by the weight load, which is proportional to the weight being determined.
