System for servicing a removable RAM package for an ambulatory medical monitor
First Claim
1. An apparatus for interfacing a portable medical monitor with a remote scanner controller comprising:
- a removable RAM package selectively couplable to the medical monitor, said removable RAM package comprising;
a power supply;
a RAM connected to a parallel multibit data bus and a parallel multibit address bus, said data bus and said address bus being connected to a first multipin connector, said first multipin connector for selectively connecting the removable RAM package to the medical monitor such that the medical monitor can store data in said RAM, said RAM being powered by said power supply; and
a real time timer circuit connected on said data bus and on said address bus, said timer circuit being powered by said power supply;
said interfacing apparatus further comprising;
means for adapting said RAM package to be serviced by the remote scanner controller through a standard serial interface, said adapting means including a serial interface connector for selectively coupling said adapting means to the scanner controller, said adapting means also including a second multipin connector adapted for mating engagement with said first multipin connector of said RAM package such that said RAM package can be selectively coupled to said adapting means, said adapting means being responsive to engagement of said first and second multipin connectors and command signals received from the remote scanner controller for enabling the scanner controller to service said RAM package.

Abstract
An apparatus for servicing a removable RAM package of an ambulatory medical monitor is disclosed. The RAM package comprises a RAM for storing blood pressure data and operating parameters and a real time timer. Both are coupled to a multipin edge connector by parallel multibit data and address buses. An adapter for servicing the RAM package by a scanner controller through a standard serial interface is provided. The adapter comprises a microcomputer chip coupled between an RS-232 serial interface and a multipin edge connector for mating engagement with the edge connector on the RAM package. Servicing includes writing and reading data from the RAM package, and reading and setting the time in the real time timer. The apparatus further includes means for controlling access to the adapter by the scanner controller using an identification and unlocking scheme. The system will not unlock if a RAM package is not coupled to the adapter.

12. A method for interfacing a portable medical monitor with a remote scanner controller comprising the steps of:
-
(a) coupling a removable RAM package to the medical monitor such that the medical monitor can store monitored data in the memory of the removable RAM package; (b) coupling the removable RAM package to a communication adapter and coupling the communication adapter to the remote scanner controller such that the removable RAM package can be placed in data communication with the remote scanner controller; (c) interrogating the remote scanner controller to insure data is not transmitted to a scanner controller which is not authorized to receive the data; (d) enabling transmission of data to the remote scanner controller if, after interrogation, the remote scanner controller is determined to be authorized to receive the data; and (e) transmitting data stored in the RAM package to the authorized scanner controller in response to commands received from the scanner controller. - View Dependent Claims (13, 14, 15)
