Abstract

A wrist-mount blood pressure monitor includes a housing having an anterior leg and a posterior leg rigidly connected together. The anterior leg is opposed and spaced a distance from the posterior leg so that a wrist is allowed to fit in the space between the legs. An inflatable bladder is positioned within the anterior leg of the housing for pressurizing an artery within the wrist. At least one stiffening member can be enclosed within the housing for assuring limited transverse movement between the anterior and posterior legs during pressurization of bladder. A blood pressure monitoring unit is operably connected to the bladder for sensing and calculating blood pressure. An auditory indicator is also provided for audibly outputting instructional information and optionally blood pressure measurement results.

Claims

1. A wrist-mount blood pressure monitor comprising:

a housing including an anterior leg and a posterior leg connected to each other, the anterior and posterior legs each including an inner wall, the inner wall of the anterior leg being opposed and spaced a distance from the inner wall of the posterior leg so as to allow access for a wrist to be positioned between the anterior and posterior legs;

an inflatable bladder within the anterior leg of the housing for pressurizing an artery within the wrist;

a portion of the inner wall of the anterior leg adjacent to the bladder comprising a flexible wall so that pressure from the bladder is transmitted to the wrist;

a blood pressure monitoring unit located within the housing; and

an auditory indicator for outputting sound.

2. The blood pressure monitor of claim 1 wherein the auditory indicator includes a speaker and sound storage medium operably connected to the speaker.

3. The blood pressure monitor of claim 1 further comprising a storage base configured to receive and support the blood pressure monitor housing, wherein the auditory indicator is located in the storage base.

4. The blood pressure monitor of claim 2 wherein the sound storage medium comprises a microchip which generates audible information.

5. The blood pressure monitor of claim 3 wherein the base further comprises a switch for activating and deactivating the auditory indicator.

6. The blood pressure monitor of claim 5 wherein the switch automatically actives the auditory indicator upon removal of the blood pressure monitor from the base and automatically deactivates the auditory indicator upon placing the blood pressure monitor on the base.

7. A wrist-mount blood pressure monitor comprising:

an anterior leg;

a posterior leg opposite and spaced a distance from the anterior leg so as to allow access for a wrist to be positioned between the anterior leg and the posterior leg;

a bridge portion that rigidly connects the posterior leg to the anterior leg;

an inflatable bladder positioned between the anterior leg and the wrist for pressurizing an artery within the wrist;

a blood pressure monitoring unit; and

an auditory indicator for outputting sound.

8. The blood pressure monitor of claim 7 wherein the auditory indicator includes a speaker and a sound storage medium operably connected to the speaker.

9. The blood pressure monitor of claim 7 further comprising a storage base configured to receive and support the blood pressure monitor housing, wherein the auditory indicator is located in the storage base.

10. The blood pressure monitor of claim 8 wherein the sound storage medium comprises a microchip which generates audible information.

11. The blood pressure monitor of claim 9 wherein the base further comprises a switch for activating and deactivating the auditory indicator.

12. The blood pressure monitor of claim 11 wherein the switch automatically activates the auditory indicator upon removal of the blood pressure monitor from the base.

13. A wrist-mount blood pressure monitor comprising:

a bottom housing including an anterior leg and a posterior leg rigidly connected together, the anterior leg and posterior leg opposite each other and spaced apart a distance to form a space which allows access for a wrist to be positioned between the legs;

a tray overlying the bottom housing;

a blood pressure monitoring unit attached to the tray;

an inflatable bladder for pressurizing an artery within the wrist, the bladder positioned between the tray and the anterior leg;

a portion of the anterior leg adjacent the bladder comprising a flexible wall so that bladder pressure is transmitted to an artery of the wrist; and

an auditory indicator for outputting sound.

14. The blood pressure monitor of claim 13 further comprising a storage base and a switch for activating and deactivating the auditory indicator, wherein the base is configured so that the auditory indicator and the switch are located in the base.

15. A wrist cuff blood pressure monitor comprising:

a generally U-shaped bottom housing including an anterior leg and a posterior leg with a generally arcuate connecting portion therebetween, the anterior and posterior legs opposite each other and spaced apart a distance to allow access for a wrist to be positioned between the legs;

a generally U-shaped tray overlying the bottom housing;

at least one stiffening member attached to the tray to limit transverse movement between the anterior and posterior legs of the bottom housing;

a blood pressure monitoring unit associated with the tray;

an inflatable bladder for pressurizing an artery of the wrist, the bladder positioned between the tray and the anterior leg;

a portion of a wall of the anterior leg adjacent the bladder comprising a fabric mesh so that bladder pressure is transmitted to an artery of the wrist; and

an auditory indicator for outputting sound.

16. The blood pressure monitor of claim 15 further comprising a storage base and a switch for activating and deactivating the auditory indicator wherein the base is configured so that the auditory indicator and the switch are located in the base.

17. The blood pressure monitor of claim 16 wherein the switch automatically activates the auditory indicator upon removing the blood pressure monitor from the base and deactivates the auditory indicator upon placing the blood pressure monitor on the base.

18. A wrist-mount blood pressure monitor comprising:

a housing including a top housing and a generally U-shaped bottom housing;

the bottom housing including an anterior leg and a posterior leg with a generally arcuate bridge portion therebetween, the anterior and posterior legs being opposite each other and spaced apart a distance to allow access for a wrist to be positioned between the legs;

a generally U-shaped tray within the housing and overlying the bottom housing;

at least one stiffening member attached to the tray to reduce transverse movement between the anterior and posterior legs;

an inflatable bladder for pressurizing an artery of the wrist, the bladder positioned between the tray and the anterior leg;

a portion of the anterior leg adjacent the bladder comprising a fabric mesh so that bladder pressure is transmitted to an artery of the wrist;

a blood pressure monitoring unit within the housing;

a display unit for indicating blood pressure measurement within the housing;

a power supply within the housing;

a storage base for storing the housing;

an auditory indicator located in the base; and

a switch for activating and deactivating the auditory indicator.

19. A method of measuring blood pressure comprising:

providing a wrist-mount blood pressure monitor including an anterior leg and a posterior leg rigidly connected to each other wherein the anterior leg is opposite and spaced a distance from the posterior leg, an inflatable bladder, a blood pressure monitoring unit, a display unit, a storage base for storing the blood pressure monitor and an auditory indicator for outputting instructional information about blood pressure monitor use;

removing the blood pressure monitor from the storage base and activating the auditory indicator;

listening to the instructional information about blood pressure monitor use;

measuring blood pressure in accordance with outputted instructional information;

obtaining results of blood pressure measurement; and

returning the blood pressure monitor to the base.

20. The method of claim 19 wherein said activating comprises automatically activating the auditory indicator upon removing the blood pressure monitor from the base.

21. The method of claim 19 wherein obtaining the results of blood pressure measurement comprises listening to the auditory indicator.
