Abstract

A blood pressure cuff includes an alignment tab, a sleeve, and an inflatable bladder disposed within the sleeve. The inflatable bladder includes a first rectangular section having a first width, a second rectangular section having a second width, wherein the second width is larger than the first width, and a tapered section extending between the first rectangular section and the second rectangular section. The tapered section may be linearly tapered or a curved taper. A length from an edge of the alignment tab to the second end of the first rectangular section adjacent the tapered section is approximately equal to a minimum arm circumference for the blood pressure cuff.

Claims

1. A blood pressure cuff comprising:

an alignment tab having an edge;

a sleeve; and

an inflatable bladder disposed within the sleeve, the inflatable bladder including a first rectangular section having a first width, a first end and a second end, and a tapered section of increasing width extending from the second end of the first rectangular section in a direction away from the alignment tab.

wherein a length from the edge of the alignment tab to the second end of the first rectangular section is approximately equal to a minimum arm circumference for the blood pressure cuff.

2. The blood pressure cuff of claim 1, wherein the inflatable bladder further includes a second rectangular section having a second width larger than the first width, wherein the tapered section extends between the first rectangular section and the second rectangular section.

3. The blood pressure cuff of claim 1, wherein the tapered section is a linear taper.

4. The blood pressure cuff of claim 1, wherein the taper section is a curved taper.

5. The blood pressure cuff of claim 1, wherein the blood pressure cuff is configured for arm circumferences between approximately 22 cm and 26 cm and the length from the edge of the alignment tab to the second end of the rectangular section is approximately 22 cm.

6. The blood pressure cuff of claim 1, wherein the blood pressure cuff is configured for arm circumferences between approximately 27 cm and 34 cm and the length from the edge of the alignment tab to the second end of the rectangular section is approximately 27 cm.

7. The blood pressure cuff of claim 1, wherein the blood pressure cuff is configured for arm circumferences between approximately 35 cm and 44 cm and the length from the edge of the alignment tab to the second end of the rectangular section is approximately 35 cm.

8. A blood pressure cuff comprising:

a sleeve;

an inflatable bladder disposed with the sleeve, wherein the bladder includes a first rectangular section having a first width, a second rectangular section having a second width, wherein the second width is larger than the first width, and a tapered section extending between the first rectangular section and the second rectangular section.

9. The blood pressure cuff of claim 8, wherein the tapered section is linearly tapered.

10. The blood pressure cuff of claim 8, wherein the tapered section is a curved taper.

11. The blood pressure cuff of claim 8, wherein the blood pressure cuff is sized for a range of arm circumferences.

12. The blood pressure cuff of claim 11, wherein the range of arm circumferences includes a first circumference and a second circumference, wherein the second circumference is larger than the first circumference.

13. The blood pressure cuff of claim 12, wherein the first width equals approximately one half the difference of the first circumference and the log of the first circumference (W₁=(C₁−

LOG(C₁))/2).

14. The blood pressure cuff of claim 13, wherein the second width equals approximately one half the difference of the second circumference and the log of the second circumference (W₂=(C₂−

LOG(C₂))/2).
