1. A portable instrument for providing rapid measurements of vital signs, comprising: a handheld, cuffless device operable during brief touch contact with one hand of a patient undergoing emergency health evaluation to produce a vital sign data set for the patient;an assembly of touch contact sensors in the device for measuring and outputting measurement values for blood pressure, pulse, blood oxygen saturation, and body temperature;a processor in the device operable under programmed control to receive and process the measurement values output by the sensors and produce the vital signs data set;a display controlled by the processor for reading out numerical values of the vital sign data set; anda wireless interface coupled to the processor for transmitting the vital sign data set to an electronic medical record in a remote database. 2. The instrument of claim 1, further comprising: a single housing having finger stations for sensing by touch contact the patient's blood pressure, pulse, blood oxygen saturation, and body temperature. 3. The instrument of claim 1, further comprising: a cuffless sensor for measuring by touch contact the patient's systolic and diastolic blood pressure;a pulse oximeter sensor for measuring by touch contact the patient's pulse and blood oxygen saturation;a thermometer for measuring by touch contact the patient's body temperature; andat least one analog-to-digital convertor circuit for converting data output by each sensor for processing by the processor. 4. The instrument of claim 1, wherein the assembly of touch contact sensors comprise: optical proximity sensors operable to detect changes in blood flow through the capillary bed of a patient's finger tip; andoperable to detect body temperature of a temporal artery. 5. The system of claim 1, wherein the processor comprises: a programmable central processing unit including, a memory for program storage; andat least program instructions for processing the sensor data and controlling the wireless interface. 6. The instrument of claim 5, wherein the wireless interface comprises: a wireless transceiver controlled by the processor operable according to a communications protocol to communicate with a remote server via a wireless network. 7. A system for emergency medical diagnosis comprising the portable instrument of claim 1, further comprising: a server connected to a program memory and a database for electronic medical records, and operable in a medical facility network of caregiver work stations and at least one emergency room workstation. 8. The system of claim 7, wherein the emergency room workstation comprises: a computer having a display and a printer coupled thereto. 9. The system of claim 7, further comprising: diagnostic analysis algorithms stored in the program memory for providing preliminary diagnosis alternatives derived from the sensor data set and the medical history data set. 10. The system of claim 9, further comprising: a selection of standard vital sign profile charts stored in the program memory and accessible during processing of the sensor data set and the medical history data set. 11. The system of claim 10, wherein: program instructions operable in the processor of the server to compare the vital sign data sets with standard vital sign profile charts and the medical history data set of the patient to produce a list of diagnostic alternatives for the patient connected to the portable instrument. 12. The system of claim 7, wherein the caregiver workstations comprise: a first program accessible from the caregiver work station for analyzing initial and subsequent vital sign data obtained at intervals of time by the portable instrument to enable identification of trends in the vital sign data. 13. The system of claim 7, comprising: a second program in the caregiver work station for displaying in a single screen display to a medical practitioner trends over time in both the vital sign data and the patient's historical data. 14. A portable instrument for providing rapid measurements of vital signs, comprising: a handheld, cuffless device enclosed in a housing and operable during brief touch contact with a patient undergoing emergency health evaluation to produce a vital sign data set for the patient;an assembly of touch contact sensors on the surface of the housing configured for measuring and outputting from the touch contact of fingers of one hand of the patient thereon the vital sign data set for blood pressure, pulse, and blood oxygen saturation;at least one analog-to-digital convertor circuit coupled to outputs of the touch contact sensors for converting its vital sign data output for processing by a processor;a processor in the device operable under programmed control to receive and process the vital sign data output by the touch contact sensors and produce the vital signs data set;a display controlled by the processor for reading out numerical values of the vital sign data set;an assembly of touch contact controls on the surface of the housing and coupled to the processor for entering commands for reading, specifying vital sign data to be measured, and sending vital sign data; anda wireless interface coupled to the processor for transmitting the vital sign data set to an electronic medical record in a remote database. 15. The instrument of claim 14, further comprising: the display configured for displaying patient identification information;a blood pressure graphical plot includes at least one histogram depicting systolic and diastolic values; andseparate graphical plots for displaying the values of the vital sign data set for pulse, blood oxygen saturation, and body temperature. 16. The instrument of claim 14, further comprising: a receptacle for connecting a bar code reader to input patient identification information to the instrument. 17. The instrument of claim 14, further comprising: a USB port for supplying a communications link from the instrument to an electronic medical record in a remote database. 18. The instrument of claim 14, wherein the assembly of touch contact sensors comprises: at least one optical proximity sensor operable to detect changes in blood flow through a patient's capillary bed of the patient's finger tip; anda touch contact sensor operable to detect body temperature of a temporal artery of the patient. 19. The instrument of claim 14, wherein: the housing is configured for carrying in a caregiver's pocket.
