Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patient monitoring apparatus, and more particularly to a storage means for temporarily storing biometric information which is an analysis result based on a biosignal derived from a patient's living body, and the temporarily stored analysis result is recorded on a recording paper. The present invention relates to a patient monitoring device that records without omission.

[0002]

2. Description of the Related Art Conventionally, a patient monitoring apparatus has been used which inputs a biological signal derived from a living body of a patient, analyzes it by performing a predetermined process, and constantly monitors the condition of the patient.
It is well known that it makes a great contribution to the diagnosis and treatment of patients. As a method of monitoring by this patient monitoring device, while displaying biological information which is an analysis result obtained based on a biological signal on a display unit, if desired, recording the biological information on a recording paper, It is commonly done. In such a patient monitoring device, there is a device in which the screen of the display unit of one device is divided so that the biological information of a plurality of patients can be simultaneously monitored. According to such a method, it is possible to monitor the biological information of a plurality of patients with one device, the efficiency of patient monitoring is improved, and it is possible to quickly perform treatment even when the condition deteriorates. In the patient monitoring device capable of monitoring the plurality of patients, the biological information of the plurality of monitored patients can be recorded on the recording paper. For example, waveform recording, alarm recording, CR
There are G records, etc. The waveform recording is to record a waveform such as an electrocardiogram or a respiratory waveform, the alarm recording is to automatically record the waveform at the time of an alarm, and the CRG recording is to record the heartbeat trend and the respiratory waveform on the same time axis. The above is to record continuously for a long time.

[0003]

Among the above-mentioned waveform recording, alarm recording, and CRG recording, CRG recording particularly has the following problems. (1) It may not be possible to simultaneously record CRGs for multiple patients. That is, as described above, the CRG recording is characterized in that the heartbeat trend and the respiratory waveform are continuously recorded on the same time axis for a long time. Therefore, while the CRG recording is being performed on a certain patient, that patient is, so to speak, monopolized the recorder of the patient monitoring device for a long time. Because of this, while the recorder is monopolized,
No CRG recordings for other patients are made. (2) CRG recording may be interrupted, and recording after interruption may not be possible. That is, the CRG recording records the analysis result based on the biological signal input to the patient monitoring device as it is, in a real-time manner. On the other hand, in the patient monitoring apparatus, the waveform recording and the alarm recording are emphasized rather than the CRG recording, and the priority is given to the handling. Therefore, the CRG recording was initially performed, but the CRG recording is interrupted, and for example, the waveform of the electrocardiogram may be recorded during the recording. In such a case, since the CRG recording is real-time recording, the recording after the interruption, that is, the CRG recording while the waveform of the electrocardiogram is being recorded cannot be performed and no data remains. As described above, regarding the CRG recording, the analysis result may be leaked between a plurality of patients (1) and in relation to the waveform recording (2), and the efficiency of patient monitoring is extremely low. An object of the present invention is to improve the patient monitoring efficiency by recording the analysis results based on the biological signals derived from the patient's living body without omission.

[0004]

[Means for Solving the Problem] The above-mentioned problems are solved by the following: input means 1A for a biological signal S1 derived from a living body of a patient, analysis means 1B for analyzing the input biological signal S1, and display means for displaying an analysis result. 1I, a temporary storage means 1B2 for temporarily storing the analysis result, and a recording means 1J for recording the analysis result stored in the temporary storage means 1B2.

[0005]

As described above, according to the present invention, as shown in FIG. 1, the temporary storage means 1B2 for temporarily storing the analysis result is provided, and the analysis result stored in the temporary storage means 1B2 is
Recording is performed by the recording means 1J. According to this configuration, when monitoring a plurality of patients while watching the screen of the display means 1I, for example, by providing four temporary storage means a, b, c, d (see FIG. 2). ), The analysis result of patient A and the analysis result of patient B can be stored alternately. Therefore, for example, the analysis results of the patients A and B can be alternated (FIG. 5), or after the analysis result recording of a patient is interrupted, the recording can be restarted (FIG. 6).
Therefore, it is possible to improve the patient monitoring efficiency by recording the analysis result based on the biological signal derived from the patient's living body without omission.
