Abstract

An object of invention is to display necessary information on a screen and display predicted information obtained by predicting the progression of the necessary information. In a bed-side information system, a body information monitor 11 measures arterial blood pressures of a patient 14. The body information monitor 11 measures systolic arterial blood pressures and diastolic arterial blood pressures, and calculates average values thereof. A Hematocrit monitor 12 calculates Hematocrit, change blood volume rate, and Venous Blood Oxygen Saturation. The body information monitor 11 transmits arterial blood pressure information to a desktop PC 15 and the Hematocrit monitor 12 transmits Hematocrit, change blood volume rate, and Venous Blood Oxygen Saturation to the desktop PC 15. The desktop PC 15 displays arterial blood pressure, Hematocrit, change blood volume rate, and Plasma Refilling Rate on a screen of a display using these information items.

Claims

1. A bed-side information system comprising:

body information acquiring means for acquiring body information of a patient;

blood purifying means for purifying blood of said patient, said blood purifying means having a blood circuit for circulating the blood;

blood information acquiring means for acquiring blood information obtained from the blood, said blood information acquiring means connecting to said blood circuit; and

display means for displaying said body information and said blood information, said display means connecting to said body information acquiring means and said blood information acquiring means,

wherein said display means has a managing table for managing said body information and said blood information, and displays said body information and said blood information on a screen according to said managing table.

2. The bed-side information system according to claim 1, wherein said display means predicts said body information and said blood information using neural network to display a predicted value.

3. The bed-side information system according to claim 2, wherein said display means comprises an analyzing section for converting retrieved blood information into blood information to be displayed, and calculating section for performing a calculation using neural network regarding said body information and said blood information to be displayed.

4. The bed-side information system according to claim 3, wherein said neural network has input layer, intermediate layer, output layer, and weight between layers, said body information and said blood information to be displayed are input, a process using neural network is performed while controlling said weight on the basis of output of said intermediate layer and/or said output layer, and said body information and said blood information to be displayed are outputted.

5. The bed-side information system according to claim 1, wherein said display means has warning means for setting an acceptable range of said body information and said blood information to be displayed to warn in the case of being out of said acceptable range.

6. The bed-side information system according to claim 1, wherein said display means displays acceptable ranges, current values, and trend-graphs of said body information and said blood information to be displayed on a screen.

7. The bed-side information system according to claim 1, wherein said managing table manages said body information, said blood information, predicted values of said body information and said blood information, acceptable ranges and current values of said body information and said blood information to be displayed, and information required to obtain information to be displayed.

8. The bed-side information system according to claim 1, wherein said body information is blood pressure, said blood information is Hematocrit, change blood volume rate, and Plasma Refilling Rate.
