Abstract

A multiple blood pressure cuff system comprises a plurality of inflatable cuffs of a range of widths and lengths which collectively share a common pressure source and a common pressure measuring device. A manifold pneumatically connects each cuff to the common pressure source and pressure measuring device and stopcock valves allow airflow to be directed to only the particular cuff in use. A mounting board is provided for affixing the system to a wall or cabinet and for conveniently supporting and displaying the cuffs that are not in use.

Claims

1. A multiple cuff blood pressure system for measuring the blood pressure of different patients comprising:

a fluid pressure source;

at least three differently-sized inflatable cuffs from the group consisting of an infant cuff, a pediatric cuff, an adult cuff, a large adult cuff and a thigh cuff, each cuff being connected to said pressure source;

means connected between said pressure source and said inflatable cuffs for directing fluid flow to a selected one of said inflatable cuffs; and

means connected to said fluid pressure source for measuring fluid pressure in said selected inflatable cuff.

2. The system of claim 1, wherein said fluid pressure source is a manual inflation bulb and said pressure measuring means is one of a mercury manometer, an aneroid pressure gauge or an electronic pressure gauge.

3. The system of claim 1, wherein said inflatable cuffs comprise all of said infant cuff, pediatric cuff, adult cuff, large adult cuff, and thigh cuff.

4. The system of claim 1, wherein said inflatable cuffs each have a different width commensurate with the circumference of the limb of the patient whose blood pressure is to be measured.

5. The system of claim 1, wherein said flow directing means comprises a valve having a fluid inlet and a plurality of fluid outlets each connected to a respective inflatable cuff, gate means in said valve for connecting the fluid inlet in fluid flow communication with a respective one of said fluid outlets.

6. The system of claim 5, wherein said pressure measuring means is connected to said valve.

7. The system of claim 1, wherein said fluid pressure means comprises only one pressure measuring element.

8. A multiple cuff blood pressure system for measuring the blood pressure of different patients comprising:

a fluid pressure source;

at least two differently-sized inflatable cuffs from the group consisting of an infant cuff, a pediatric cuff, an adult cuff, a large adult cuff and a thigh cuff, each cuff being connected to said pressure source;

means connected between said pressure source and said inflatable cuffs for directing fluid flow to a selected one of said inflatable cuffs; and

means connected to said fluid pressure source for measuring fluid pressure in said selected inflatable cuff, said flow directing means comprising a manifold including a plurality of valves connected in series, each of said inflatable cuffs being connected to a respective one of said valves, said fluid pressure source and said pressure measuring means being connected to said manifold.

9. The system of claim 8, wherein said valves comprise stopcocks each having an open position in which fluid pressure flows through said stopcock and to the inflatable cuff connected thereto and a closed position in which fluid flows through said stopcock with flow interrupted to the inflatable cuff connected thereto.

10. The system of claim 8, wherein each of said inflatable cuffs is connected to its respective valve by an elongated flexible tube.

11. The system of claim 8, wherein said manifold comprises a plurality of first pipe sections connecting said valves in series, a second pipe section connecting said fluid pressure source to one of said valves at one end of said manifold and a third pipe section connecting said pressure measuring means to the other end of said manifold.

12. A multiple cuff blood pressure system for measuring the blood pressure of different patients comprising:

a fluid pressure source;

at least two differently-sized inflatable cuffs from the group consisting of an infant cuff, a pediatric cuff, an adult cuff, a large adult cuff and a thigh cuff, each cuff being connected to said pressure source;

means connected between said pressure source and said inflatable cuffs for directing fluid flow to a selected one of said inflatable cuffs, said flow directing means comprising a manifold assembly supported on a mounting plate adapted to be secured to a vertical surface, said mounting plate having a plurality of hangers, each of said hangers supporting a respective one of said inflatable cuffs; and

means connected to said fluid pressure source for measuring fluid pressure in said selected inflatable cuff.

13. A multiple cuff blood pressure system comprising:

a manifold assembly comprising a plurality of fluid pressure valves connected in series;

a pressure source connected to said manifold assembly and a pressure measuring device connected to said manifold assembly;

a plurality of inflatable blood pressure cuffs each connected to a respective one of said valves, said valves being selectively operable to connect said pressure source and said pressure measuring device to only one of said inflatable cuffs.

14. The system of claim 13, wherein said valves are stopcocks.

15. The system of claim 14, wherein each of said stopcocks has an open position in which fluid pressure flows through said stopcock and to the inflatable cuff connected thereto and a closed position in which fluid flows through said stopcock with flow interrupted to the inflatable cuff connected thereto.

16. The system of claim 13, wherein said inflatable cuffs each have a different width.

17. The system of claim 13, wherein said manifold assembly is secured to a mounting plate, said inflatable cuffs being connected to said valves by elongated flexible tubes, said mounting plate having a plurality of hangers for supporting said inflatable cuffs when said cuffs are not in use.

18. The system of claim 13, wherein said pressure source is a manual inflation bulb and said pressure measuring device is one of a mercury manometer, aneroid pressure gauge or an electronic pressure gauge.

19. The system of claim 13, wherein said manifold assembly has a first end and a second end, said pressure source being connected to said first end and said pressure measuring device being connected to said second end.

20. The system of claim 13, wherein said pressure source and said pressure measuring device have a common connection to said manifold assembly.

21. A multiple cuff blood pressure system for measuring the blood pressure of different patients comprising:

a fluid pressure source;

at least three differently-sized inflatable cuffs for measuring the blood pressure of patients with different size arms, all said cuffs being connected to said pressure source;

valve means connected between said pressure source and said inflatable cuffs for directing fluid flow to a selected one of said inflatable cuffs; and

means connected to said fluid pressure source for measuring fluid pressure in said selected inflatable cuff.

22. The system of claim 21, wherein said inflatable cuffs comprise an infant cuff, a pediatric cuff, an adult cuff, a large adult cuff, and a thigh cuff.

23. The system of claim 21, wherein said fluid pressure means comprises only one pressure measuring element.

24. A multiple cuff blood pressure system comprising:

a fluid pressure source;

a plurality of differently-sized inflatable cuffs, each being connected to said pressure source;
