Abstract

Systems, devices, and methods are provided for simultaneous assessment of a subject'"'"'s subjective and objective pain states. These include a dolorimeter arrangement for determining a subject'"'"'s cutaneous pain tolerance level at any site on the body. In certain preferred embodiments, the dolorimeter is hand-held and utilizes a sonar distance-measuring device. In another aspect, the systems, devices, and methods of the current invention include platforms effective for implementing pain monitoring methods that include delivering pain questionnaires to patients over a period of time points. The platforms may harvest analgesic drug data from nurses attending the patients, and may provide simple statistical analysis of collected data useful both at the bedside and at central base-stations. The platforms may provide additional functions based on analysis of patient pain data. Preferred embodiments of the current invention combine the dolorimeter arrangement with the platforms for implementing pain monitoring methods.

Claims

1. A method for monitoring pain of a patient, said method comprising:

a) providing a patient communication device;

b) providing a data processor capable of communicating with the patient communication device;

c) delivering a pain questionnaire to the patient at each of a series of time points using the patient communication device to generate pain questionnaire results;

d) communicating the pain questionnaire results to the data processor; and

e) processing the pain questionnaire results using the data processor, thereby monitoring the pain of a patient,

wherein the pain questionnaire is selected from the group consisting of a Visual Pain Analog Scale, a Visual Mood Analog Scale, a Pain Severity Scale and a Pain Reilef Scale.

2. The method of claim 1, wherein the pain questionnaire comprises at least two members selected from the group consisting of a Visual Pain Analog Scale, a Visual Mood Analog Scale, a Pain Severity Scale and a Pain Relief Scale.

3. The method of claim 1, wherein the pain questionnaire comprises at least three members selected from the group consisting of a Visual Pain Analog Scale, a Visual Mood Analog Scale, a Pain Severity Scale and a Pain Relief Scale.

4. The method of claim 1, wherein the pain questionnaire comprises a Visual Pain Analog Scale, a Visual Mood Analog Scale, a Pain Severity Scale and a Pain Relief Scale.

5. The method of claim 1, wherein the patient communication device comprises a patient device microprocessor, wherein the communicating is performed automatically, and wherein the data processor is a separate processor from the patient device microprocessor.

6. The method of claim 1, further comprising triggering an effector function based on the process pain questionnaire results.

7. The method of claim 1, wherein the delivering of the pain questionnaire is performed by the patient without assistance of medical personnel.

8. The method of claim 1, wherein the delivering of the pain questionnaire is performed other than as part of a pain-stimulation or sensory stimulation procedure, and without stimulating a pain response in the patient.

9. A method for monitoring pain of a patient, said method comprising:

a) providing a patient communication device, wherein the patient communication device includes a heat beam dolorimeter;

b) providing a data processor capable of communicating with the patient communication device;

c) delivering a pain questionnaire to the patient at each of a series of time points using the patient communication device to generate pain questionnaire results;

d) communicating the pain questionnaire results to the data processor; and

e) processing the pain questionnaire results using the data processor, thereby monitoring the pain of a patient.

10. A patient pain management system comprising:

a) a patient communication device comprising a patient device microprocessor effective for executing a pain questionnaire software application,

wherein the patient communication devise includes a heat beam dolorimeter; and

b) a data processor effective for automatically communicating with the patient communication device.

11. The system of claim 10, wherein the heat beam dolorimeter utilizes a sonar ranging sensor.
