Abstract

A portable hand-held monitor (1) for monitoring vital signs is connected, via a single connector (7), with a cable (9). This cable ends up in a combiner (10) which, in turn, receives plugs (12a to 12d) leading, via cables (11a to 11d), to single sensors or transducers applied to a patient. Portable hand-held monitor (1) comprises a display (3) and internal memory means, in order to store recorded vital signs and to transmit them to a remote computer later on. As only a single cable (9) is required for connection with combiner (10), patient monitoring becomes quite easy if the combiner (10), cable (9) and the associated sensors and interconnection cables are left at or near the patient. In this case, a plug (8) connected with cable (9) has simply to be inserted into connector (7), in order to start data acquisition. The same simple approach may be used to monitor the next patient, and so on.

Claims

1. A method for retrieving and/or monitoring vital signs of a patient, wherein n≧

2 sensors comprising electrocardiogram electrodes, a temperature sensor and/or a cuff for measuring non-invasive blood pressure, are connected to connection means and are applied to a patient, comprising the steps of;

connecting at least 2 of said connection means to a combining means;

linking said combining means to a portable, hand held electronic data acquisition unit via m releaseable connector(s), m<

n both m and n being integers, said releasable connector(s) directly connected to said data acquisition unit by cable(s);

retrieving vital signs information from at least one of said n sensors and transmitting said vital signs information via said combining means and releasable connector(s), to said electronic data acquisition unit; and

displaying said vital signs information on a display contained in said portable electronic data acquisition unit.

2. A method according to claim 1 further comprising the step of:

storing said vital signs information in said portable, hand held electronic data acquisition unit.

3. A method according to claim 2, said method comprising the further steps of

connecting said portable, hand held, electronic data acquisition unit to a remote computer;

and

transmitting said vital signs information stored in said, hand held, portable electronic data acquisition unit at least partially to said remote computer.

4. A method according to claim 2, said method comprising the further steps of:

connecting said portable, hand held, electronic data acquisition unit to a remote computer;

transmitting data from said remote computer to said portable, hand held, electronic data acquisition unit; and

storing said data in said portable hand held electronic data acquisition unit.

5. A method according to claim 4, wherein said data is patient information, patient care-related information, alarm and/or scheduling information.

6. A method according to claim 5, wherein said portable, hand held electronic data acquisition unit generates an alarm if patient care is due, and accepts and stores a confirmation on effected patient treatment.

7. A method according to claim 2, wherein a memory module includes a memory, said method comprising the further step of:

8. A system for retrieving and/or monitoring a multiplicity of vital signs of a patient, comprising:

n≧

2 sensors, where n is an integer, for application to the patient;

n≧

2 connection means, each of said connection means connected to one of said n sensors;

combining means for releasable connection with at least two of said connection means; and

a portable, hand held electronic data acquisition unit releasably connected to said combining means via m releasable connectors, where m is an integer and m<

n for retrieving data from said sensing means, said data acquisition unit including a display for displaying said vital signs.

9. A system according to claim 8 wherein said combining means comprises an inflatable cuff usable for non-invasive blood pressure measurement, said cuff including at least one of an electrocardiogram electrode a respiration electrode, or an oxygen saturation sensor.

10. A system according to claim 8 wherein said electronic data acquisition unit includes memory means for storing data indicative of said vital signs.

11. A system according to claim 10, wherein said electronic data acquisition unit is a portable electronic data acquisition unit and includes a base station that is connectable with said portable electronic data acquisition unit, said base station including support means for said portable electronic data acquisition unit.

12. A system according to claim 11, wherein said support means includes automatic electrical connection means for mating with said portable electronic data acquisition unit.

13. A system according to claim 11, wherein said portable electronic data acquisition unit includes at least one rechargeable battery, and said automatic electrical connection means including automatic battery recharging connection means.

14. A system according to claim 11 wherein said base station and said portable electronic data acquisition unit enable transmission of at least part of said vital signs information from said portable electronic data acquisition unit to said base station.

15. A system according to claim 11 wherein said base station and said portable electronic data acquisition unit enable transmission of patient data, patient care-related data, alarm or scheduling information from said base station to said portable electronic data acquisition unit.

16. A system according to claim 15 wherein said electronic data acquisition unit generates an alarm signal when an alarm time occurs or has expired, or when patient care has not been acknowledged timely.

17. A system according to claim 10 wherein said memory means is removable together with said display and is insertable into a remote station containing a multiplicity of insertion slots.
