PATIENT MONITORING SYSTEM WITH BLOOD PRESSURE MEASUREMENT CAPACITY
First Claim
1. Apparatus for recording the pulse wave form generated at a measurement site on a patient'"'"'s body comprising:
- A) rigid housing means for being brought into proximity to an artery at the measurement site, B) pressure transducer means mounted to one side of said housing means for generating an electrical signal that is a function of pressure at an input thereto, C) bladder means mounted to the other side of said housing for forming a sealed, fluid-filled cavity about said passage means at said housing means, and D) passage means formed through said housing means for connection to said pressure transducer means input whereby when said bladder means is brought into contact with the skin at the measurement site, said pressure transducer means produces a representation of a wave-form signal corresponding to the pressure changes at the measurement site.

Abstract
A patient monitoring system including a sensing-recording device that attaches to a patient and a probe utilized by attending personnel at a trauma site. After an initial interaction between the probe and the sensing-recording device, the sensing-recording device samples one or more physiological parameters and stores time stamped readings in a first memory. The probe is adapted to take other measurements including pulse data, download the data from the first memory of the sensing-recording device, manipulate the collective data and return data to a second memory in the sensing-recording device. The probe is also adapted to combine data from the sensing-recording device and its pulse data to provide a blood pressure measurement.

9. A system for obtaining a measurement of a patient'"'"'s blood pressure comprising:
-
A) sensing-recording means for attachment to the patient including a memory, sensing means for measuring a physiological parameter, and means for storing time-stamped samples of the physiological parameter in said memory, and B) a probe for being applied with an application pressure to a measurement site remote from the site of said sensing-recording means, said probe including;
i) means for generating a signal representing a pulse wave form at the measurement site, ii) a probe memory, iii) means for storing time-stamped samples of the signal in said probe memory, iv) means for retrieving the time-stamped samples from said memory in said sensing-recording means, and v) means for generating a representation of the patient'"'"'s blood pressure based upon the information in both of said time-stamped samples. - View Dependent Claims (10, 11, 13, 14, 15, 16)

17. A sensing-recording device for providing to an output device a history of a medical parameter of a patient comprising:
-
A) a housing, B) a power supply in said housing, B) means in said housing for storing in a memory data that represents the medical parameter, and D) normally open switching means between said generating means and said power supply, said switching means including means operable when said switching means is closed for locking said switching means in the closed position thereby blocking any attempt to disconnect said power supply from said generating means. - View Dependent Claims (18, 19, 20)
