United States Patent5291399   
Link to this pagehttp://www.wikipatents.com/5291399.html
Inventor(s)Chaco; John (Seymour, CT)
AbstractA distributed data processing network includes multiple memory card databases at terminal nodes of the network. The network is programmed to automatically perform routine communications operations such as conveying identification information between the terminal nodes and interior nodes. The network is implemented in a hospital environment and the databases include information on patients and hospital personnel. Using the automatic communications facilities of the network patient information from the database is displayed at a nurse station when the patient initiates a nurse-call or automatically when medication, also recorded on the card, is due. In addition, the system may be used to locate hospital personnel and equipment, to audit the use of controlled substances and to automatically assemble emergency response teams.

central processor means, located at the second remote location, for receiving the message sent by said second communications means to maintain a central database and for determining the location of said entity.

2. The apparatus of claim 1 wherein:

the entity information includes data relating to the amount of time that the database is coupled to the first communications means; and

the second communications means includes means for calculating a fee based for the entity identified by the identifying information based on the time data provided by said first communications means.

3. The apparatus of claim 2, further including:

means for detecting attempts to tamper with one of the database, the first communications means and the second communications means; and

means for automatically transmitting data disclosing the detected tampering attempts to said second communications means.

4. The apparatus of claim 3 wherein the first communications means includes a first source of operational power and a second self contained source of operational power, the second source of operational power being coupled to apply power to at least a portion of the first communications means upon an interruption of power from the first source of operational power.

5. The apparatus of claim 1 wherein:

said first communications means includes means for transmitting said entity information including said identification information using electromagnetic radiation; and

said second communications means includes means for receiving said entity information transmitted by said first communications means.

6. The apparatus of claim 5 wherein:

said second communications means includes means for broadcasting data to said first communications means using electromagnetic radiation; and

said first communications means includes;

means for receiving the data broadcast by the second communications means; and

means for storing at least a portion of the data received from the second communications means into said portable database means.

7. The apparatus of claim 6 wherein the information transmitted by said first communication means is transmitted using a predetermined signal strength for the electromagnetic radiation and first communications means includes means for momentarily increasing the signal strength used to transmit said entity information.

8. The apparatus of claim 7 further including:

a plurality of second communications means distributed over an area;

wherein said central processor means includes a display device, coupled to said plurality of second communications means, (1) for causing each of said second communications means to send a message to said first communications means and to await for a response therefrom, (2) for identifying, based on the received responses, one of said second communications means as being physically close to said first communications means, (3) for displaying the position of said identified

means for storing at least a portion of the data received from the second communications means into said portable database means.

9. The apparatus of claim 6 further including:

a plurality of said second communications means;

a telephone network including a plurality of telephone sets coupled to respectively different ones of said plurality of second communications means; and

means, coupled to said telephone network for identifying which of the second communications means is physically close to the first communications means and for establishing a connection from a predetermined node in the telephone network to the telephone set coupled to the identified second communications means.

10. Apparatus for automating routine communication comprising:

portable database means for storing entity information including identification information about an entity;

first communications means, removably coupled to said portable database means for retrieving the entity information including the identification information from said portable database means and for sending the retrieved information to a first remote location;

second communications means, located at said first remote location, for receiving the retrieved information sent by said first communications means and for sending a message including at least a portion of said retrieved information to a second remote location; and

central processor means, located at the second remote location, for receiving the message sent by said second communications means to maintain a central database; wherein

the portable database means is a memory card;

the entity information includes medical information pertaining to a patient in a hospital;

the first communications means includes a nurse call station having means for requesting assistance from a nurse; and

the second communications means includes a central nurse station having means for displaying the identification information and medical information sent from the database in response to the request for assistance from said first communication means.

11. The apparatus of claim 10, further including:

identification means, configured to be non-removably affixed to the patient, for holding machine-readable identification information relating to the patient;

reading means, coupled to said nurse call station for reading said machine-readable identification information; and

means, coupled to said nurse call station, for comparing the machine-readable identification information to the identification information held by said memory card.

12. The apparatus of claim 11 wherein:

said medical information includes data identifying prescribed medications;

said reading means includes means for reading machine-readable data identifying one of the prescribed medications from a container which holds the one prescribed medication; and

said first communications means includes:

means for searching the information held in the memory card for data identifying the prescribed medications which matches the data provided by said reading means from said container of prescribed medication; and

means for indicating an alarm condition when no match is found between the data held by the memory card and the data provided by said reading means from the container of prescribed medication.

13. The apparatus of claim 12 wherein:

the data identifying prescribed medications includes data specifying a time at which the medication is to be administered;

the first communications means includes:

clock means for developing digital signals representing the current time;

comparison means for comparing the digital samples provided by the clock means with the medication time data held by said memory card; and

means for causing said first communications means to send the identification information and the data identifying one of the prescribed medications to said second communications means when said comparison means finds a match between the signals provided by the clock means-and the medication time data for said one prescribed medication.

14. The apparatus of
