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 comprising:

vital sign detecting means for detecting at least one kind of vital sign;

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

judging means for judging a correlation between the vital sign and a medical apparatus operation condition on the basis of said vital sign 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 sign 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 2, wherein the judging means further judges whether or not a variation in said vital sign 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 indicating that said predetermined range is exceeded.

4. 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 indicating a state of the operation condition of the medical apparatus.

5. The vital sign monitor according to claim 1, wherein the judging means judges whether or not a variation in the vital sign 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.

6. The vital sign monitor according to claim 5, further comprising:

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

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 sign is within the range of variation estimated.

7. The vital sign monitor according to claim 1, wherein the medical apparatus is a ventilator.

8. The vital sign monitor according to claim 1, wherein the medical apparatus is an infusion pump.

9. A vital sign monitor comprising:

vital sign detecting means for detecting at least one kind of vital sign;

medical apparatus operation detecting means for detecting an operation of a medical apparatus;

judging means for judging whether a variation in the vital sign is within a range of variation estimated from the operation of the medical apparatus, and issuing an instruction signal depending on the judgement;

first indicating means for indicating a first alarm based on the instruction signal; and

second indicating means for indicating a second alarm based on the operation of the medical apparatus after the first alarm is indicated.

10. A vital sign monitor comprising:

vital sign detecting means for detecting at least one kind of vital sign;

medical apparatus operation detecting means for detecting an operation of a medical apparatus;

judging means for judging whether the vital sign varies irrespective of the operation of the medical apparatus, and issuing an instruction signal depending on the judgement;

first indicating means for indicating a first alarm based on the instruction signal; and

second indicating means for indicating a second alarm based on the operation of the medical apparatus after the first alarm is indicated.
