Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a home patient monitoring device, and more specifically, the present invention relates to a home patient monitoring device, and more specifically, the present invention relates to a home patient monitoring device, and more specifically, it transmits signals (medical diagnostic signals) derived from physiological phenomena of the patient to a remote location while the patient remains at home. This invention relates to an at-home patient monitoring device that can transmit data to a central monitoring device side (a monitoring bag installed in a hospital, etc. where the attending physician is present).

[Conventional Technique #II] Normally, when a patient visits a doctor, he or she goes to the hospital and receives an examination. However, it takes time to travel to a hospital and receive a medical examination, especially when the patient lives far away. On the other hand, so-called VANs (value-added communication networks), which exchange information between two points using communication lines such as telephone lines, have been put into practical use. Therefore, methods have been considered that use such communication means to transmit the patient's condition to a central monitoring device in a distant hospital or the like where the attending physician is located. For this reason,
A home patient monitoring device is used to detect and transmit home patient diagnostic signals to a remote central monitoring device.

In this type of system, it is desirable not to monopolize 100% of the telephone line at the patient's home, and for this reason, the store/batch method (sending data all at once once a certain amount of data has been collected) is desirable. has no choice but to adopt. Therefore, in response to this, the central monitoring device 2111, that is, the attending physician's side, requires something like a personal computer with a modem.

[Problem to be Solved by the Invention] However, if the intensive monitoring device is complicated and complicated for the attending physician to handle, the attending physician will have difficulty in handling it. For this reason, the spread of this type of home patient monitoring device is subject to certain restrictions, which may become a bottleneck to its widespread use.

The present invention has been made in view of these problems, and it is an object of the present invention to provide a home patient monitoring device that can be easily handled by the attending physician.

[Means for Solving the Problems 1] The present invention for solving the above-mentioned problems includes a means for collecting signals derived from physiological phenomena of a living body, and a means suitable for processing the signals and providing them for diagnosis in a @Hiragi manner. The present invention is characterized by comprising a means for creating a chart according to a predetermined protocol as a two-dimensional pattern, and a means for disassembling the chart as a two-dimensional pattern according to a predetermined protocol, transmitting and receiving it, or assembling it and transmitting it to a distant central monitoring device.

[Operation] Diagnostic information is transmitted from the device on the patient side according to a certain protocol, and the diagnostic information is automatically output on the receiving side. This facilitates handling on the part of the attending physician.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The figure is a configuration block diagram showing one embodiment of the present invention. In the figure, 1 is a patient at home, 2 is a sensor-equipped transmitter attached to a part of the patient's body for detecting diagnostic information, and 3 is a wireless signal from the sensor-equipped transmitter 2. This is a data collection and transmission device that collects diagnostic information from patients 1 at home and transmits the data to a remote central monitoring device. These sensor-equipped transmitter 2 and data collection/transmission device are provided on the patient's side at home, and constitute a telemetry (non-transportation receiving system). Here, the sensor-equipped transmitter 2 may detect one type of diagnostic information, or two or more types of diagnostic information.

As for the specific type, those suitable for continuously examining the patient's condition, such as blood pressure and electrocardiogram, are suitable.

The exchanges 4 and 5 and the communication line 6 are a communication network.
It consists of

Reference numeral 7 denotes a facsimile machine that receives diagnostic information sent via a communication network. This facsimile device 7 does not need to have any special functions, and may be a general-purpose device. Reference numeral 8 denotes a transaction file device for storing sent information (not limited to diagnostic information), 9 a telephone, and 10 recording paper on which diagnostic information output from the facsimile device 7 is written. The operation of the device configured as described above will be explained as follows.

A sensor-equipped transmitter 2 attached to a part of the body of a patient 1 at home detects signals originating from physiological phenomena of the patient, and uses wireless telemetry to collect and transmit data installed at a specific location in the patient's home. Sent to device 3. The data collection and transmission device 3 amplifies the received signal to a predetermined level, converts it into digital data, and stores the converted diagnostic information in its internal memory. Here, the storage unit may be tens of minutes to several hours, or in some cases, several days. When the stored data reaches a predetermined amount, the data collection and transmission device 3 collects the data and sends it out to the communication network. Therefore, the data processing method is batch processing. By performing batch processing, it is possible to avoid a situation where the telephone at the patient's home remains 100% exclusive.

Next, the following functions can be considered as the functions of the data collection and transmission device 3.

■ Function to receive and store patient data (or biological signals) ■ Patient to be transmitted from the above stored data ■ Function to create a graph image with D. message ■ Function for sending at regular or continuous intervals A timer function for starting ■ A function to disassemble the transmitted image and send it using a protocol such as 03. ■ A calling and network control function to enable the various functions mentioned above. ■ An emergency function based on the received diagnostic information. A function that detects a situation and automatically transmits the data, etc. ■ A function that changes its own operating functions upon receiving instructions from the attending physician. Data collection and transmission is necessary when transmitting data to the central monitoring device via the communication network. It is conceivable that the device 3 processes the received diagnostic information and summarizes it in a format suitable for viewing by the attending physician, for example, in a report format or a graph format representing changes over time. Specific examples of this type of format include biological signals such as a trend pulse of a heart rate diagram and a specific scene of an electrocardiogram.

Various methods can be considered for the timing of transmission. An extremely common method is to transmit data at predetermined fixed time intervals, but it is also possible to transmit data at irregular intervals (for example, when the amount of data reaches a certain amount). Alternatively, the information may be transmitted in response to emergencies or emergencies. At the time of this transmission, it is conceivable that the facsimile machine 7 at the destination (central monitoring device side) is in use for another purpose or is receiving data from another patient. As a transmission method for dealing with such a situation, there is, for example, a polling transmission method. In this case, polling transmission means that the central monitoring device issues a call via the network, the patient at home picks up the call, and starts transmission in response to the incoming call according to a predetermined procedure. Also,
For example, the transmission protocol is 0 for facsimile.
A method such as 2°G3 can be used.

The diagnostic information sent from the patient at home in this way is
It reaches the central monitoring device side via the subscriber line 11→exchange 4→communication line a6→exchange 5→subscriber line/2. The arrived diagnostic information of the patient is recorded by the facsimile device 7 on the recording paper 10 as image information as shown in the figure. In addition to diagnostic data, this recording paper 10 contains graphs or patient information.
D. Data collection time or time period can also be recorded. This diagnostic information can also be stored in the transaction file system 8 if desired. The attending physician can objectively diagnose by observing the recording paper 10.

Since the patient ID is also recorded on the recording paper 10,
The attending physician can identify the patient. Therefore, if necessary, the patient 1 can be called from the telephone 9 and verbally given prescription instructions.

Possible functions of the central monitoring device on the attending physician's side include the following.

■A function that receives data using the facsimile protocol and automatically enters and registers it into a computer without human intervention.■A function that creates a received transaction file and adds important data to it and files it for backup or semi-permanent recording. Furthermore, according to the present invention, the attending physician only needs to observe the recording paper 10 recorded by the facsimile device 7, and can easily diagnose the condition without performing any other complicated procedures.

In the above description, an example has been taken in which diagnostic information from a patient at home is transmitted to a data collection and transmission device by wireless telemetry. This configuration is convenient because the patient can move around freely. however,
The present invention is not limited to this, and may be a system in which the sensor and the data collection/transmission device are directly connected via a signal line.

[Effects of the Invention] As described above in detail, according to the present invention, diagnostic information from a patient at home is transmitted to the central monitoring device using a communication network, and diagnostic information detected by the patient's device at home is transmitted. Since the information is processed in advance into an easy-to-read format such as a graph before being sent, the attending physician who receives the data can obtain the information in a form that can be immediately diagnosed using a facsimile machine, etc. A home patient monitoring device can be provided that can facilitate the use of home patient monitoring devices.
