Abstract

The invention relates to an arrangement for a patient monitor arranged to measure one or more parameters from a patient from other than urine or the urinary tract. To improve the ergonomics of patient monitoring work, the arrangement comprises a sensor (8) that is arranged between a patient urinary tract catheter (6) and a urine collection container (7) or the like and that is arranged to measure at least the flow or volume of the patient'"'"'s urine output, and means (9) for conveying the data measured to the patient monitor (2)

Claims

1. An arrangement for a patient monitor (2) arranged to measure one or more parameters from a patient (1) from other than urine or the urinary tract, characterized in that the arrangement comprises a sensor (8, 8a, 8b, 8c, 8d) arranged between a patient urinary tract catheter (6) and a 5 urine collection container (7) or the like and arranged to measure at least the flow or volume of the patient'"'"'s urine output, and means (9) for conveying the data measured to the patient monitor (2).

2. An arrangement as claimed in claim 1, characterized in that the sensor (8, 8a, 8b, 8c, 8d) is arranged to measure also urine temperature.

3. An arrangement as claimed in claim 1 or 2, characterized in that the sensor comprises a flow sensor (8a) based on heat transfer.

4. An arrangement as claimed in claim 1 or 2, characterized in that the sensor comprises a flow sensor (8b) based on ultrasound.

5. An arrangement as claimed in claim 1 or 2, characterized in that the sensor comprises a flow sensor (8c) based on a turbine.

6. An arrangement as claimed in claim 1 or 2, characterized in that the sensor comprises a flow sensor (8d) based on a pressure difference.

7. An arrangement as claimed in claim 2, characterized in that the arrangement is arranged to calculate the patients core temperature by means of the information obtained from the urine temperature measurement.

8. An arrangement as claimed in any one of claims 1 to 7, characterized in that the sensor (8) is arranged to measure the momentary urine flow and/or the volume cumulated in a unit of time.

9. An arrangement as claimed in any one of claims 1 to 8, characterized in that the patient monitor (2) is arranged to measure the patient'"'"'s EKG, NIBP, oxygen saturation and respiratory gases.
