Abstract

A monitor and recorder system having a monitor unit for gathering vital sign data from a patient and a memory module for automatically recording the data. Means are provided for protecting the data from accidental or intentional deletion of the data or corruption or damage to the memory module without proper authorization. The data is recorded in a circular memory such that when data must be deleted, the last-recorded data is deleted first. A procedure is disclosed for preserving all data for at least a minimal period of time in case an event such as a patient death occurs.

Claims

1. A method of encouraging the recordation of patient vital sign data, comprising the steps of:

(a) providing a monitor and recorder system, the monitor and recorder system including at least one sensing device, a microprocessor, a memory module, and a user interface subsystem;

(b) during operation of the monitor and recorder system, automatically determining, via an interlock system and the microprocessor, whether the memory module is prepared to accept vital sign data received by monitor and recorder system;

(c) if, in the determining step, it is determined that the memory module is prepared to accept vital sign data;

(i) receiving vital sign data information from a patient via the at least one sensing device of the monitor and recorder system,

(ii) displaying the vital sign data, and

(iii) recording the vital sign data on the memory module,

(iv) wherein the receiving, displaying, and recording steps are carried out at least partly under control of the microprocessor; and

(d) if, in the determining step, it is determined that the memory module is not prepared to accept vital sign data, carrying out the steps, at least partly via the microprocessor, of;

(i) via the user interface subsystem, warning an operator of the monitor and recorder system that the memory module is not prepared to accept vital sign data, and

(ii) concurrently therewith, controlling the monitor and recorder system to automatically prevent the vital sign data from being displayed,

(iii) wherein the warning and controlling steps are carried out at least partly under control of the microprocessor.

2. The method of claim 1, wherein the monitor and recorder system is a bedside monitor and recorder device, and wherein the method further comprises the step of positioning the monitor and recorder system adjacent the patient.

3. The method of claim 1, wherein the user interface subsystem includes a display unit, and wherein the data displayed in the displaying step is displayed in a graphical format.

4. The method of claim 1, wherein the user interface subsystem includes a display unit, and wherein the data displayed in the displaying step is displayed in a numerical format.

5. The method of claim 1, wherein the user interface subsystem includes a display unit, and wherein the data displayed in the displaying step is displayed in a textual format.

6. The method of claim 1, wherein the step of providing the monitor and recorder system includes providing a user interface subsystem that incorporates a display unit.

7. The method of claim 1, wherein the step of providing the monitor and recorder system includes providing a display unit that includes a plurality of distinct display units.

8. The method of claim 1, wherein the step of providing the monitor and recorder system includes providing a display unit that is a single display unit that includes a plurality of display areas therein.

9. The method of claim 1, further comprising a step, if in the determining step it is determined that the memory module is prepared to accept vital sign data, of externally communicating data, representative of the vital sign data gathered from the patient, to a remote device via a communication interface of the monitor and recorder system.

10. The method of claim 9, wherein the step of externally communicating data to a remote device includes externally communicating data to a remote device that is not physically present in a room in which the patient is located.

11. The method of claim 9, wherein the step of displaying data includes displaying data on the remote device.

12. The method of claim 11, wherein the step of displaying data includes displaying data on the remote device and also includes displaying data on a display unit disposed adjacent to the monitor and recorder system.

13. The method of claim 9, further comprising a step of connecting the remote device to the monitor and recorder system via a communications network.

14. The method of claim 9, wherein the remote device is a personal computer, the method further comprising connecting the personal computer directly to the monitor and recorder system.

15. The method of claim 9, wherein the step of providing the monitor and recorder system includes incorporating the memory module in the remote device.

16. The method of claim 15, further comprising a step of communicatively connecting the remote device is to the monitor and recorder system via wired connection.

17. The method of claim 15, further comprising a step of communicatively connecting the remote device is to the monitor and recorder system via wireless connection.

18. The method of claim 1, wherein the providing step includes enclosing the memory module and the monitor and recorder system within the same integral enclosure.

19. The method of claim 1, wherein the microprocessor is enclosed in a first structure, and wherein the providing step includes enclosing the memory module in a second structure that is separate from the first structure.

20. The method of claim 19, wherein the providing step includes enclosing the memory module in a second structure that is separate from the first structure but securely fastened to the exterior thereof.

21. The method of claim 19, wherein the providing step includes electrically connecting the memory module and the other elements of the monitor and recorder system.

22. The method of claim 21, further comprising steps, if in the determining step it is determined that the memory module is prepared to accept vital sign information received by the monitor and recorder system, of:

externally communicating data, representative of the vital sign data gathered from the patient, to a remote device via a communication interface; and

displaying data on the remote device.

23. A method of encouraging the recordation of patient vital sign data, comprising the steps of:

(a) providing a monitor and recorder system, the monitor and recorder system including at least one sensing device, a microprocessor, a memory module, and a user interface subsystem;

(b) during operation of the monitor and recorder system, automatically determining, via an interlock system and the microprocessor, whether the memory module is prepared to accept vital sign data received by monitor and recorder system;

(c) if, in the determining step, it is determined that the memory module is prepared to accept vital sign data;

(i) receiving vital sign data information from a patient via the at least one sensing device of the monitor and recorder system, and

(ii) recording the vital sign data on the memory module,

(iii) wherein the receiving and recording steps are carried out at least partly under control of the microprocessor; and

(d) if, in the determining step, it is determined that the memory module is not prepared to accept vital sign data;

(i) controlling operation of the monitor and recorder system at least by providing a user-perceptible indication, via the user interface subsystem, to warn an operator of the monitor and recorder system that the memory module is not prepared to accept vital sign data, and

(ii) concurrently therewith, controlling the monitor and recorder system to automatically prevent the vital sign data from being received thereby,

(iii) wherein controlling steps receiving, displaying, and recording steps are carried out at least partly under control of the microprocessor.
