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.
11 Claims, 5 Drawing Figures This invention relate's to devices for checking blood pressure and particularly to a device which can be utilized by an individual for checking his own blood pressure.
BACKGROUND OF THE INVENTION In checkingblood pressure, it iscommon to utilize a device which comprises a' band that is wrapped around the'limb and has a pump and guage associated therewith. The physician or nurse checking the blood pressure manipulates the pressure while simultaneously checking the pulse to determine the pressure at which the pulse is stopped. Such a device is complex and difficult to use. Accordingly, it is not practical for use by individuals for'che'cking their own 'blood pressure.
Accordingly, among the objects of the invention are to provide a device which can be readily manipulated by an individual and which will indicate to the individual when he has'a moderate or severejcaseof high blood pressure. i i i H b SUMMARY OF'TI-IE INVENTION The device for checking blood pressureembodying the invention comprises an inflatable hollow band adapted to encircle a li'mb and pump means connected to said band for inflating'saidband. Aifirst pressure relief valve is associated withthe band and is adapted to relieve pressure at a'.first. predetermined pressure, and an on-off valve is-associated with thefirst pressure relief valve for disabling the first pressure'relief valve. A second pressure relief valvle is associated with the hollowband and setforrelieving the pressure of the" band at a higher setting than the first pressure relief valve such that, .the blood pressurev may be checked by actuating the pump means until 'the pulse of the person being checked is interrupted insaid limb or until the first pressure relief valve operates torelieve 'the pressure, thereafter actuating the on-off valveif the first pressure relief valve has been actuated to disable said 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.
DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagrammatic view showing the device embodying the invention in use.
FIG. 2 is a partly schematic view of the device.
FIG. 3 is a longitudinal sectional view of the device.
FIG. 4 is a sectional view taken along the line 44 in FIG. 3.
FIG. 5 is a fragmentary sectional view taken along the line 5-5 in FIG. 3.
DESCRIPTION sdth'at pumped into the tube will not escape back through the pump. A first pressure relief valve 15 set to relieveai'r in 'the tube 12 at a 'predetermined pressure, 'for example lbs., isassociated with the tube. In
addition an on-off valve 16 is provided which will disable the pressure relief'valve 15. A second pressure relief valve 17 is'also associated with'the tube and is set to relieve the pressure at a higher pressure than valve 15, on the order to I09 lbs.
A typical pressure relief valve 15 and disabling on-off valve, 16 is shown in FIG. 5 and comprises a spring loaded ball 18 that is'normally'urged against a seat 18a. When the pressure exceeds the setting of the spring, the air in the tube 10 is relieved. The valve includes a cap 19 which can be screwed downwardly to engage the ball and disable the pressure relief valve.
For convenience of the user. valves l5, 17 may have identifying indiciathereon such as different colors. In the event that it is desired to quickly dissipate the pressure in the band .10, a manually operated vent valve may be associated with the band either directly or on the tube 12, as is conventional with the usual devices for checking blood pressure.
The invention can be more readily understood by reference to the 'diagrammatic showing in FIG. 2. A person decidingtocheck his blood pressure applies the band 10 to a limb such as an arm and begins the application of pressure bymanipulating the pump 13. Simultaneously, the person keeps checking his pulse. If the pulse stops before the pressure relief valve 15 relieves the pressure, his blood pressure is normal. If however the pressure relief valve 15 relieves the pressure before the pulse is stopped, then the person knows that his blood pressure is higher than normal. The person then manipulates the disabling device 16 thereby cutting off the pressure relief valve 15 and continues the pumping. As the pressure increases he continues to monitor his pulse and": if the pulse stops then he knows that his pressure is'somewhat over the setting of the valve 15 but less than that of the valve 17. However, if the pulse continues until the pressure relief valve 17 is actuated to relieve'the pressure, then the person knows that his blood pressure is quite high and should seek medical assistance immediately.
It can thus be seen that there has been provided a device for checking blood pressure which can be manipulated by an individual simply without excessive skill and which will indicate to the individual whether he has a moderate or severe case of blood pressure.
