Abstract

A physiological parameter measuring apparatus is configured to perform a screening for a likelihood of the critical congenital heart disease, based on the oxygen saturations at two locations on a body of a patient and the difference between the oxygen saturations, and to display the likelihood as a result of the screening. The physiological parameter measuring apparatus manages, with respect to each patient, a scheduled time for starting the screening, the result of the screening, and information relating to the patient. The physiological parameter measuring apparatus can display a first screen containing information relating to the scheduled time, a second screen for receiving the instruction to perform the screening, and a third screen containing the result of the screening. A physiological parameter measuring system includes sensors to be attached to the body at the two locations, and the physiological parameter measuring apparatus.

Claims

1. A physiological parameter measuring apparatus for performing a screening for critical congenital heart disease, the apparatus comprising:

a first sensor configured to be attached to a first portion of a body of a patient;

a second sensor configured to be attached to a second portion of the body, the second portion being different from the first portion;

a memory storing computer-readable instructions; and

a processor configured to execute the computer-readable instructions, which when executed cause the processor to control the physiological parameter measuring apparatus to;

control acquisition of a first oxygen saturation at the first portion and a second oxygen saturation at the second portion of the body, based on measurement signals from the first sensor and the second sensor;

control calculation of a difference between the first oxygen saturation and the second oxygen saturation;

upon receipt of an instruction to perform the screening, and based on the first and second oxygen saturations and the difference, control performance of the screening for a likelihood of the critical congenital heart disease with respect to the patient, and to output the likelihood as a result of the screening;

control management of, with respect to each patient, a scheduled time for starting the screening, the result of the screening, and information relating to the patient; and

control a display configured to receive an input by an operator, to display, in a switchable manner, a first screen including a list of patients and containing information relating to the scheduled time for starting the screening for each patient, a second screen for receiving the instruction to perform the screening, and a third screen containing the result of the screening,

wherein the first sensor has an indication of a hand or a foot,

wherein the second sensor has an indication of the hand or the foot that is not indicated on the first sensor, and

wherein the physiological parameter measuring apparatus has indications corresponding to the indications of the hand and the foot on the first and second sensors, at portions where the first and second sensors are connected respectively.

2. The physiological parameter measuring apparatus according to claim 1, wherein the processor, when the computer-readable instructions are executed, controls the physiological parameter measuring apparatus to manage the scheduled time for a next screening of each patient, and

controls the display to display, on the first screen, at least part of the information relating to each patient in an order of the scheduled time for the next screening of each patient.

3. The physiological parameter measuring apparatus according to claim 1, wherein the processor, when the computer-readable instructions are executed, controls the display to display, on the second screen, an image object having a shape that changes in accordance with the result of the screening.

4. The physiological parameter measuring apparatus according to claim 1,

wherein the processor, when the computer-readable instructions are executed, controls the physiological parameter measuring apparatus to calculate a reliability of measurement signals from the first sensor and a reliability of measurement signals from the second sensor, and

controls the display to enable to accept the instruction to perform the screening on the second screen when the reliabilities of the measurement signals from the first and second sensors are both equal to or greater than a predetermined value.

5. The physiological parameter measuring apparatus according to claim 1, further comprising a reader configured to read a tag that is attached to each patient, the tag including an identifier containing identification information specific to the patient,

wherein the processor, when the computer-readable instructions are executed, controls the physiological parameter measuring apparatus to accept the instruction to perform the screening from the second screen only when identification information of a patient who is scheduled to next undergo the screening matches the identification information acquired by reading the identifier of the tag attached to the patient by the reader.

6. The physiological parameter measuring apparatus according to claim 1, wherein the processor, when the computer-readable instructions are executed, controls the physiological parameter measuring apparatus to transmit via a network the result of the screening to an external device when the screening result is positive.

7. A physiological parameter measuring system of performing a screening for critical congenital heart disease, the system comprising:

a first sensor configured to be attached to a first portion of a body of a patient;

a second sensor configured to be attached to a second portion of the body, the second portion being different from the first portion; and

a physiological parameter measuring apparatus, wherein the physiological parameter measuring apparatus comprises;

a memory storing computer-readable instructions; and

a processor configured to execute the computer-readable instructions, which when executed cause the processor to control the physiological parameter measuring apparatus to;

control acquisition of a first oxygen saturation at the first portion and a second oxygen saturation at the second portion, based on measurement signals from the first sensor and the second sensor;

control calculation of a difference between the first oxygen saturation and the second oxygen saturation;

upon receipt of an instruction to perform the screening, and based on the first and second oxygen saturations and the difference, control performance of the screening for a likelihood of the critical congenital heart disease with respect to the patient, and to output the likelihood as a result of the screening;

control management of, with respect to each patient, a scheduled time for starting the screening, the result of the screening, and information relating to the patient; and

control a display configured to receive an input performed by an operator, to display, in a switchable manner, a first screen containing information relating to the scheduled time, a second screen for receiving the instruction to perform the screening, and a third screen containing the result of the screening,

wherein the first sensor has an indication of a hand or a foot,

wherein the second sensor has an indication of the hand or the foot that is not indicated on the first sensor, and

wherein the physiological parameter measuring apparatus has indications corresponding to the indications of the hand and the foot on the first and second sensors, at portions where the first and second sensors are connected respectively.

8. The physiological parameter measuring system according to claim 7, wherein the processor, when the computer-readable instructions are executed configured to control the display to display, on the first screen, at least part of the information relating to each patient in an order of the scheduled time for a next screening of each patient.

9. The physiological parameter measuring system according to claim 7, wherein the processor, when the computer-readable instructions are executed configured to control the display to display, on the second screen, an image object having a shape that changes in accordance with the result of the screening.
