<First embodiment>
FIG. 1 shows a configuration diagram of a monitoring network system configured by using an embodiment of the biological information collecting and displaying apparatus according to the present invention. The monitoring network system includes a network 11, a central monitor 12 that displays a signal waveform on a display unit based on a biological signal, a server 16 that manages a biological information table collection device and a patient ID held by each device, and a patient. Biological signal acquisition means 1-1 to 1-i, 2-1 to 2-i, such as a sphygmomanometer and an electrocardiograph for obtaining a biological signal, n-1 to ni, 19-1 to 19- connected to i, bedside monitors 13-1 to 13-n, 15 which are a plurality of biological information collection and display devices that collect biological signals, and biological signals acquisition means 18-1 to 18-i connected to biological The transmitter 14 is configured to collect and transmit signals. Here, the server 16 may exist alone or may be included in the central monitor 12. When the patient ID search is performed by monitoring the network, the server 16 and the central monitor 12 may be omitted.

  The central monitor 12 receives biological signals transmitted from the bedside monitors 13-1 to 13-n, the transmitter 14, and the bedside monitor 15, and displays a waveform based on the signals in a corresponding display area of the display unit. It is.

  The bedside monitors 13-1 to 13-n are bedside monitors provided in, for example, a hospital room. The transmitter 14 is used when carrying a patient, for example. The bedside monitor 15 is provided in an operating room, for example. It is provided. The bedside monitors 13-1 to 13-n and 15 are configured, for example, as shown in FIG. That is, the display unit 42 (which may not include the transmitter 14) configured by an LCD or the like, which is configured around the CPU 41, the transmission / reception unit 43 that is connected to the network 11 and transmits / receives data, a blood pressure sensor, and an electrocardiogram sensor Collecting unit for collecting biological signals from biological signal acquisition means 1-1 to 1-i, 2-1 to 2-i,..., N-1 to ni, 19-1 to 19-i 44. An input unit 45 for inputting a patient ID and a mode instruction is a main component.

  The CPU 41 includes holding means 21, detection means 22, search means 23, biological signal reception means 24, and display control means 25. The holding means 21 holds a patient ID of a patient who is a target of biosignal collection and display in the apparatus. Here, the patient ID is an identifier unique to each patient, and may be directly input from the input unit 45, may be generated by the CPU 41, or from a device (for example, a central monitor or a server) that manages the patient ID. It may be delivered. In this embodiment, a normal patient setting and a patient setting (hereinafter referred to as an interbed function) for receiving a transfer of a biological signal obtained by a destination bedside monitor even when the patient moves are possible.

  The detection means 22 detects an incapable measurement state in which a biological signal cannot be obtained from the collection unit 44 or a temporary exit from the input unit 45. The incapable measurement state refers to a state in which all the biological signal acquisition means are disconnected from the electrode, the probe is off, the connector is disconnected, etc., and no biological signal can be obtained in the collecting unit 44. “Only electrode detachment” is not included in the unmeasurable state defined here. The temporary leaving is input by the input unit 45.

  The search means 23 obtains a biological signal from the patient having the patient ID held in the holding means 21 via the network 11 when the detection means 22 detects an inability to measure or an input of temporary leaving. The device is searched. The search means 23 takes in information sent from the transmitter 14 and other bedside monitors from the network 11, detects whether a desired patient ID is included, and stores the patient ID and the holding means included in the information. When the patient IDs of 21 are matched and matched, the transmitter 14 and another bedside monitor are identified as a device that obtains a corresponding biological signal. Whether or not they match may be inquired of the server 16 or may be determined from information flowing on the network.

  The biological signal receiving unit 24 receives a biological signal obtained by the device (transmitter 14 or bedside monitor 15) searched by the searching unit 23. The display control unit 25 displays a signal waveform on the display unit 42 based on the biological signal received by the collecting unit 44 or the biological signal receiving unit 24.

  In the system configured as described above, the bedside monitors 13-1 to 13-n are assumed to have already been input or assigned patient IDs and held in the holding unit 21. The CPU 41 of the bedside monitors 13-1 to 13-n performs interbed function processing by a program corresponding to the flowchart shown in FIG. Further, it is assumed that the transmitter 14 and the bedside monitor 15 do not have a patient at the beginning, and the holding means 21 does not hold a patient ID.

  When a patient is connected to the biological signal acquisition means 1-1 to 1-i, 2-1 to 2-i,..., N-1 to ni and a biological signal is obtained from the collection unit 44, FIG. 3, the CPU 41 detects this (S10), and via the collection unit 44, the biological signal acquisition means 1-1 to 1-i, 2-1 to 2-i, ..., n- The biological signal is obtained from 1 to ni, and the waveform corresponding to the biological signal is displayed on the display unit 42 (S11).

  In this case, for example, a display example on the bedside monitor 13-1 is as shown in FIG. In FIG. 4, an electrocardiogram (HR), invasive blood pressure (IBP), and a pulse wave waveform are displayed on the display unit 42. In this state, it is detected whether measurement is impossible or temporary exit is input (S12).

  The bedside monitor 13-1 is associated with a patient whose patient name is “Photoelectric Taro” and whose patient ID is # K0001. In order for the patient whose patient ID is # K0001 to undergo surgery, the connection from the biological signal acquisition unit 1-1 to 1-i is disconnected, and the biological signal acquisition unit 18-1 to 18-i of the transmitter 14 is disconnected. Suppose you get a connection. Prior to this, in the transmitter 14, the patient ID # K0001 is input and held in the holding means 21. The patient ID is a unique identifier assigned to each patient.

  FIG. 5 shows a display example on the bedside monitor 13-1 when the patient whose patient ID is # K0001 leaves the connection from the biological signal acquisition means 1-1 to 1-i. In FIG. 5, it can be seen that the electrocardiogram (HR), invasive blood pressure (IBP), and pulse wave waveforms are not displayed on the display unit 42.

  In the bedside monitor 13-1 from which the patient with the patient ID # K0001 is separated, the process branches to YES in step S12 in which an inability to measure or the presence of temporary leaving is detected, and another bedside monitor connected to the network 11 is detected. The transmitter 14 is searched for a device having the same patient ID as the patient ID # K0001 held in the holding means 21 of the bedside monitor 13-1 (S13).

  Subsequent to step S13, it is detected whether the corresponding device is specified (S14). If not specified, step S13 is repeated. In this example, since there is a patient whose patient ID is # K0001 in the transmitter 14, the transmitter 14 has an apparatus having the same patient ID as the patient ID # K0001 held in the holding means 21 of the bedside monitor 13-1. It is specified (S14).

  The bedside monitor 13-1 receives the biological signal obtained by the identified device (here, the transmitter 14), and displays a signal waveform on the display unit 42 based on the received biological signal (S15). A display example in this case is shown in FIG. In this case, as shown in FIG. 6, all the waveforms of the electrocardiogram (HR), invasive blood pressure (IBP), and pulse wave are displayed on the display unit 42 again. However, as shown in the upper center of the screen of the display unit 42, “TRANS-01 in transit” is displayed, and identification information for identifying a device that obtains a biological signal corresponding to the waveform is associated with the waveform. Displayed.

  Subsequent to step S15, it is detected whether or not a biological signal can be obtained from the collection unit 44 of the bedside monitor 13-1 (S16), and a biological signal can be obtained from the collection unit 44. Advances to step S11, obtains a biological signal from the biological signal acquisition means 1-1 to 1-i via the collection unit 44, and displays a waveform corresponding to the biological signal on the display unit 42 (S11).

  If a biological signal is not obtained from the collection unit 44 of the bedside monitor 13-1 in step S16, the device specified in step S14 (here, the transmitter 14) is in a non-measurement state (measurement impossible state or temporary withdrawal). It is detected whether the patient ID of the holding means 21 of the device has been changed (S17). If NO, a biological signal is continuously obtained from the specified device, and the biological signal is sent to the display unit 42. The corresponding waveform is displayed (S15).

  If “YES” in step S17, the process proceeds to step S13, and the same patient ID # K0001 held in the holding means 21 of the bedside monitor 13-1 is connected to the bedside monitor or transmitter 14 connected to the network 11. A search is made for a device having an ID (S13), and the processing after step S13 is performed. As described above, when a patient with the patient ID # K0001 receives measurement by the transmitter 14 and then receives measurement by the bedside monitor 13-1, another bedside monitor (for example, a bedside monitor, for example) Even when measurement is started in the side monitor 15), the waveform corresponding to the biological signal of the patient whose patient ID is # K0001 is displayed on the display unit 42 of the bedside monitor 13-1, and necessary monitoring is performed. It can be carried out.
