Device for checking blood pressure
First Claim
1. In a device for checking blood pressure, the combination comprising an inflatable hollow band adapted to encircle a limb, pump means connected to said band for inflating said band, a first pressure relief valve on said band and set to relieve pressure at a first predetermined pressure, on-off valve means associated with said first pressure relief valve for disabling said first pressure relief valve, a second pressure relief valve associated with said hollow band and set for relieving the pressure of said band at a higher setting than said first pressure relief valve such that, the blood pressure may be checked by actuating said pump means until the pulse of the person being checked is interrupted in said limb or until the first pressure relief valve operates to relieve the pressure, thereafter actuating said on-off valve means if said first pressure relief valve has been actuated to disable said first pressure relief valve and continuing the application of pressure until the pulse of the individual is interrupted or the second pressure relief valve is actuated indicating a more serious condition of blood pressure.

Abstract
A device for checking blood pressure, comprising an inflatable hollow band adapted to encircle a limb and having pump means connected to said band for inflating said band. A first pressure relief valve is provided on the band and is adapted to relieve pressure at a first predetermined pressure, an on-off valve is associated with the first pressure relief valve for disabling said first pressure relief valve. A second pressure relief valve is associated with the hollow band and set for relieving the pressure of the band at a higher setting than the first pressure relief valve such that, the blood pressure may be checked by actuating said pump means until the pulse of the person being checked is interrupted in said limb or until the first pressure relief valve operates to relieve the pressure, thereafter actuating the on-off valve if the first pressure relief valve has been actuated to disable the pressure relief valve and continuing the application of pressure until the pulse of the individual is interrupted or the second pressure relief valve is actuated indicating a more serious condition of blood pressure.

-
7. The combination set forth in claim 6 wherein said indicia means comprises first and second colors.
-
8. The combination set forth in claim 1 wherein said band comprises a generally rectangular band comprising spaced layers defining a hollow space therebetween, opposed edges on said band having means thereon for joining said edges to provide the hollow band encircling the limb.
-
9. In a device for checking blood pressure, the combination comprising an inflatable hollow band adapted to encircle a limb, manually operable pump means connected to said band for inflating said band, a one-way valve associated with said pump means, a first pressure relief valve on said band and set to relieve pressure at a first predetermined pressure, on-off valve means associated with said first pressure relief valve for disabling said first pressure relief valve, a second pressure valve associated with said hollow band and set for relieving the pressure of said band at a higher setting than said first pressure relief valve such that, the blood pressure may be checked by actuating said pump means until the pulse of the person being checked is interrupted in said limb or until the first pressure relief valve operates to relieve the pressure, thereafter actuating said on-off valve means if said first pressure relief valve has been actuated to disable said first pressure relief valve and continuing the application of pressure until the pulse of the individual is interrupted or the second pressure relief valve is actuated indicating a more serious condition of blood pressure.
-
10. The combination set forth in claim 9 wherein said first pressure relief valve is set for relief at 150 lbs. pressure and said second pressure relief valve is set for relief at 190 lbs. pressure.
-
11. In a method of checking blood pressure by utilizing an inflatable hollow band adapted to encircle a limb, pump means connected to said band for inflating said band, a first pressure relief valve on said band and set to relieve pressure at a first predetermined pressure, on-off valve means associated with said first pressure relief valve, for disabling said first pressure relief valve, a second pressure relief valve associated with said hollow band and set for relieving the pressure of said band at a higher setting than said first pressure relief valve such that the steps comprise encircling a person'"'"''"'"'s limb with said hollow band, actuating said pump means until the pulse of the person being checked is interrupted in said limb or until the first pressure relief valve operates to relieve the pressure, thereafter actuating said on-off valve means if said first pressure relief valve has been actuated to disable said first pressure relief valve and continuing the aPplication of pressure until the pulse of the individual is interrupted or the second pressure relief valve is actuated indicating a more serious condition of blood pressure.
