DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a health information terminal device for inputting measured physiological information of a subject and remotely communicating with a doctor or the like.

[0002]

2. Description of the Related Art In recent years, from the importance of home health care,
Various systems have been proposed in which a subject transmits physiological information measured at home to a remote doctor via a communication line, and the doctor diagnoses the result. For example, a subject measures physiological information such as body temperature, blood pressure, heart rate, and weight at home and inputs the measured physiological information to a computer from a keyboard or the like,
The computer transmits the input physiological information to a remote host computer via a telephone line or the like, and the doctor diagnoses the subject based on the physiological information transmitted to the host computer. With such a system, the burden of the subject going to the hospital can be reduced, and health management at home can be performed.

[0003] When diagnosing with such a system, physiological information that a subject inputs at home is very important, and there must be no incorrect input. However, a subject who is unfamiliar with the keyboard may make an input error, and the input operation may be complicated.

To solve such a complicated operation, there is, for example, a system proposed in Japanese Patent Application Laid-Open No. Hei 8-131409. In this system, first connect the terminal to the host computer, download the past physiological information of the subject stored in the host computer, and enter "increase" or "decrease" based on the downloaded past physiological information Then, it is determined as the physiological information measured this time.

[0005]

However, the conventional configuration has the following problems. First, the computer of the subject is connected to the host computer to download the past physiological information of the subject, so that a waiting time occurs before the physiological information measured this time is input. The subject's physiological information is important information of the individual and should not be downloaded by others. Therefore, in general, ID
Authentication is required, and the downloaded physiological information must be encrypted and can be decrypted only by a specific terminal such as the subject's computer.

[0006] These essential procedures, such as authentication and decryption, cause a longer waiting time. The use of an analog telephone line, which is most widely used as a means of transmitting data to a remote location, is a factor that further increases the waiting time, and is inconvenient for the subject.

Further, physiological information to be diagnosed by a doctor or the like is input by the operation of the subject. If incorrect physiological information is transmitted by an erroneous operation of the subject, the doctor or the like makes an erroneous diagnosis. Could be Therefore, it is preferable that there is an operation for confirming whether or not the inputted physiological information is correct before transmission. However, this confirmation operation may be troublesome and may cause usability to deteriorate.

[0008] The present invention solves the above-mentioned conventional problems, and allows a subject to input physiological information by simple operations, minimizes waiting time, and transmits incorrect physiological information. The purpose is to improve the usability without using it.

[0009]

In order to solve the above-mentioned conventional problems, a health information terminal device according to the present invention comprises a storage means for storing past values of physiological information of a subject, and a past value of the storage means. , And operating means for inputting new physiological information of the subject by changing the reference.

[0010] Thus, the past physiological information of the subject can be read from the storage means provided in the health information terminal device, and the physiological information measured this time can be input by changing the past physiological information by the operating means. Therefore, when the subject inputs the physiological information, it can be input by a simple operation, and since there is no need to first connect to the host computer, the waiting time can be minimized and the usability can be improved.

The configuration was adopted.

With this configuration, when the subject makes a decision input using the decision operation section, the comparison section compares the value stored in the temporary storage section with the past value in the storage section, and when the difference is greater than or equal to a predetermined value, displays the result on the display section. Display confirmation text. When the subject again inputs the confirmation using the confirmation operation unit, the value stored in the temporary storage unit is determined as the physiological information. Physiological information is unlikely to be far away from the past values.If the values are far away, there is a possibility that the input is incorrect.In such a case, the confirmation operation must be performed again for confirmation. As a result, it is possible to prevent erroneous physiological information from being determined, and to improve usability without performing unnecessary confirmation operations.

The operation means 7 is configured to include an increase / decrease operation unit 8, a determination operation unit 9, and a reset operation unit 10. The increase / decrease operation unit 8 includes an UP key 11 for increasing the value stored in the temporary storage unit 3 and a DOWN key 1 for decreasing the value.
2 inclusive. Operation information of the subject increase / decrease operation unit 8 is input to the control unit 2, and the stored value of the temporary storage unit 3 is updated in response to the operation input, and the update result is displayed on the work display unit 6.

Therefore, the examinee presses the UP key 11 while viewing the stored value of the temporary storage section 3 displayed on the work display section 6 to increase the stored value of the temporary storage section 3 or presses the DOWN key 12 to decrease the stored value. The operation information of the confirmation operation unit 9 is input to the control unit 2. When the decision unit 4 receives the confirmation information, the storage value of the temporary storage unit 3 at that time is decided as new physiological information of the subject. Further, the operation information of the reset operation unit 10 is also input to the control unit 2, and when the reset operation information is input, the control unit 2 reads out the stored value of the previous physiological information stored in the storage unit 1, and Write to. When the test subject has accidentally changed the stored value of the temporary storage unit 3 to a value that is far apart during updating by the increase / decrease operation unit 8, the reset operation unit 10 performs a reset operation to return the value to the previous value and again. Can be increased or decreased.

The determining unit 4 includes a comparing unit 13 and a display unit 5

When the determination information is input to the control means 2 by the following, the comparison unit 13 compares the stored value of the temporary storage unit 3 at that time with the stored value of the previous physiological information stored in the storage unit 1,
If the difference is within a predetermined range, the value stored in the temporary storage unit 3 is determined as new physiological information. When there is a difference exceeding a predetermined value, a confirmation sentence is output to the confirmation display unit. Therefore, if the subject operates the confirmation operation unit 9 again, the stored value of the temporary storage unit 3 is determined as new physiological information. However, if the reset operation is performed by the reset operation unit 10, past stored values are read from the storage unit 1 and increased / decreased. Redo doing the operation.

In general, the range in which the physiological information of the same subject fluctuates is limited to some extent. For example, if the body weight is measured every day, the range of fluctuation from the previous day is about 2 kg or less, Since there is a high possibility that the input is incorrect, a confirmation sentence is displayed to have the subject confirm the input, thereby preventing the user from deciding with the incorrect input.

Numeral 15 denotes a transmission means, which inputs new physiological information of the subject determined by the control means 2 from the temporary storage unit 3,
The data is transmitted to a remote host computer (not shown) via a communication line 16 such as a telephone line. A remote doctor or the like makes a diagnosis by looking at the physiological information of the subject transmitted by the host computer. This allows the subject to receive a doctor's diagnosis at home.

Next, a specific operation of inputting weight as physiological information will be described with reference to the flowchart of FIG. 2 and the display screens of FIGS. When the system is turned on, a menu screen shown in FIG. 3 is first displayed, and the subject selects physiological information to be input from body temperature, blood pressure, pulse, and weight, and presses a corresponding button. For example, if the subject presses the weight button, the operation is performed according to the flowchart shown in FIG.

As shown in FIG. 2, when the weight is selected, the previously measured last weight stored in the storage means 1 is first written into the working weight which is the value stored in the temporary storage unit 3 (S-1). . The work weight is displayed on the work display section of the display means 5 (S-2). Here, the display screen is as shown in FIG. If the previous measured value was 60 kg, “60 kg” is displayed on the work display unit 6.

When the subject performs the reset operation, the previous measurement value stored in the storage unit 1 can be read out again and written in the temporary storage unit 3. Therefore, while the subject performs an increase / decrease operation to update the stored value of the temporary storage unit 3, if the value becomes far from a new measured value to be erroneously input, the reset operation is performed. Thus, the operation can be restarted from the previous measured value, and the usability for an erroneous operation is improved.

Further, in this embodiment, the comparison unit 13 and the confirmation display unit 14 are provided. When the subject makes a decision input with the decision operation unit 9, the comparison unit 13 stores the value stored in the temporary storage unit 3 and the storage means. 1 is compared with the previous measurement value, and when the difference is greater than or equal to a predetermined value, a confirmation sentence is displayed on the confirmation display unit 14. Since it is determined as a value, it is possible to prevent erroneous measurement values from being determined and transmitted, and to improve usability without performing unnecessary confirmation operations.
