Abstract

The vital signs detected by vital sign detecting means 101 and the data detected by medical apparatus operation detecting means corresponding to each vital sign are sent to judging means 103. The judging means 103 judges the correlation between the vital signs and the medical apparatus operation state, and further judges whether a variation in vital signs detected by the vital sign detecting means 101 is within a range of variation estimated from the medical apparatus operation detected by the medical apparatus operation detecting means 102. And indicating means 104 indicates an alarm or a message on the basis of a judgement result of whether or not the variation in vital signs is within the estimated range of variation.

Claims

1. A vital sign monitor characterized by comprising:

vital sign detecting means for detecting vital signs;

medical apparatus operation detecting means for detecting the operation of a medical apparatus; and

judging means for judging the correlation between the vital signs and a medical apparatus operation condition on the basis of said vital signs detected by the vital sign detecting means and the operation condition of the medical apparatus detected by the medical apparatus operation detecting means.

2. The vital sign monitor according to claim 1, further comprising:

indicating means for indicating the correlation between the vital signs and the medical apparatus operation condition as an alarm or a message depending upon an instruction signal of the judging means.

3. The vital sign monitor according to claim 1, wherein the judging means judges whether or not a variation in the vital signs detected by said vital sign detecting means is within a range of variation estimated from the operation of said medical apparatus detected by said medical apparatus operation detecting means.

4. The vital sign monitor according to claim 3, wherein the indicating means indicates at least one of an alarm and a message on the basis of a judgement result whether or not the variation in said vital signs is within the range of variation estimated.

5. The vital sign monitor according to claim 2, wherein the judging means further judges whether or not the variation in said vital signs detected by said vital sign detecting means is beyond a predetermined range in a state where any change in the operation condition of said medical apparatus is not detected by said medical apparatus operation detecting means, and said indicating means indicates an alarm displaying that said predetermined range is exceeded.

6. The vital sign monitor according to claim 2, wherein in the case where the indicating means indicates the alarm in accordance with the correlation when the operation condition of the medical apparatus is detected by the medical apparatus operation detecting means, the judging means instructs the indicating means to indicate an alarm displaying a state of the operation condition of the medical apparatus.

7. A vital sign monitor comprising:

vital sign detecting means for detecting vital signs;

clinical staff practice recognizing means for detecting and recognizing a practice of a clinical staff; and

judging means for judging the correlation between said vital signs and the practice of the clinical staff on the basis of said vital signs detected by the vital sign detecting means and the practice of the clinical staff recognized by the clinical staff practice recognizing means.

8. The vital sign monitor according to claim 7, further comprising:

indicating means for indicating the correlation between the vital signs and the practice of the clinical staff as an alarm or a message depending upon an instruction signal of the judging means.

9. The vital sign monitor according to claim 7, characterized in that said judging means judges whether or not a variation in the vital signs detected by the vital sign detecting means is within a range of variation estimated from the practice of the clinical staff recognized by the clinical staff practice recognizing means.

10. The vital sign monitor according to claim 9, wherein the indicating means indicates at least one of an alarm and a message on the basis of a judgement result of whether or not the variation in the vital signs is within the estimated range of variation.

11. The vital sign monitor according to claim 8, wherein said judging means further judges whether or not a variation in said vital signs detected by said vital sign detecting means is beyond a predetermined range in a state where no change in the practice of the clinical staff is detected by said clinical staff practice recognizing means, and said indicating means indicates an alarm displaying that said predetermined range is exceeded.

12. The vital sign monitor according to claim 8, wherein in the case where the indicating means indicates the alarm in accordance with the correlation when the operation condition of the medical apparatus is detected by the medical apparatus operation detecting means, the judging means instructs the indicating means to indicate an alarm displaying a state of the operation condition of the medical apparatus.

13. The vital sign monitor according to claim 7, wherein when said medical apparatus is operated, the clinical staff practice recognizing means recognizes the practice of the clinical staff.

14. The vital sign monitor according claim 7, wherein the clinical staff practice recognizing means recognizes the practice of said clinical staff by an image-pickup device.

15. The vital sign monitor according to claim 14, wherein when the image-pickup means recognizes one of the condition that the clinical staff changes the body position of a patient and that a body movement of said patient is subjected, the indicating means is inhibited to indicate the alarm.
