Abstract

A pneumatic pump assembly adapted to be integrated into a device for monitoring heart pulse rates from radial arterial sources. The pump assembly includes a pneumatic pump with a bulb component, a self-sealing flapper valve and a tube connecting the pump with an inflatable bladder. Sensors are disposed at the bladder whereby they can be oriented with regard to the radial artery of the wearer upon inflation or release of air pressure in the bladder. Typically, the pump assembly and monitoring device are worn at the wrist of the user.

Claims

1. A pneumatic pump assembly including,

support means,

pump means formed in said support means,

an inlet valve in said support means for selectively admitting fluid into said pump means,

said inlet valve adapted to be self-sealing when pressure is applied to said pump means whereby fluid in said pump means is not passed through said inlet valve,

a pressure relief valve in said support means to selectively pass fluid therethrough from said pump means,

bladder means mounted in said support means,

said bladder means connected to receive fluid from said pump means and be inflated thereby when pressure is applied to said pump means, and

sensor means mounted to said bladder means such that the positional orientation of said sensor means is dependent upon the inflation level of said bladder means.

2. The pump band recited in claim 1 wherein,

said sensor means comprises optical sensors.

3. The pump band recited in claim 1 including,

strap means

said pneumatic pump assembly comprises a unitary assembly unit which is selectively detachable from said support means.

4. The pump band recited in claim 3 wherein,

said support means is made of metal.

5. The pump band recited in claim 3 wherein,

said support means is made of leather.

6. The pump band recited in claim 3 wherein,

said support means is made of rubber.

7. The pump band recited in claim 3 wherein,

said support means is made of plastic.

8. The pump band recited an claim 3 including,

electronic assembly means for monitoring heart pulse rate signals mounted to said support means.

9. The pump band recited in claim 8 including,

electrical conductor means in said support means connected from said sensor means to said electronic assembly means.

10. The pump band recited in claim 8 wherein,

said electronic assembly includes an electronic power source.

11. The pump band recited in claim 8 wherein,

said electronic assembly includes a readout display means.

12. The pump band recited in claim 11 wherein,

said display means is a liquid crystal display.

13. The pump band recited in claim 1 wherein,

said pressure relief valve includes a press button actuator.

14. The assembly recited in claim 1 wherein,

said bladder means selectively extends outwardly from said support means.

15. The assembly recited in claim 1 wherein,

said support means comprises a flexible structure.

16. A monitoring unit comprising:

(a) a pump assembly,

said pump assembly comprising a bulb, a self-sealing inlet valve for selectively admitting fluid to said bulb, an inflatable bladder for selectively receiving fluid from said bulb and an exhaust valve for selectively releasing fluid from said inflatable bladder;

(b) a band internally compartmentalized to receive said pump assembly;

(c) sensor means mounted at said inflatable bladder;

(d) housing means attached to said band;

(e) electronic assembly means contained within said housing means;

(f) conductor means electronically connecting said sensor means with said electronic assembly means;

(g) display means connected to said electronic assembly means; and

(h) power source means connected to said electronic assembly means.

17. The pump band recited in claim 16 wherein,

said sensor means produce first signals representative of a body parameter,

said electronic assembly means receive said first signals and operate thereon to produce second signals, and

said display means receives said second signals and produces an output display representative of said body parameter.
