1. A bio signal measuring apparatus comprising:
- a body operable to be attached to a skin of a patient;
an electrocardiogram measuring unit disposed on the body and operable to be attached to the skin of the patient to measure an electrocardiogram signal of the patient;
a heart sound sensor disposed on the body and operable to contact the skin of the patient to measure a heart sound signal of the patient; and
a controlling unit disposed on the body and operable to obtain bio information including at least a heart rate from the electrocardiogram signal with reference to the heart sound signal, and to detect a window such that the window contains a first heart sound and a second heart sound of the heart sound signal,wherein the bio information is obtained based on a result of determining whether an R peak of the electrocardiogram signal exists in the detected window.

Abstract
A bio signal measuring apparatus. The bio signal measuring apparatus includes an electrocardiogram measuring attached to the skin of a patient to measure an electrocardiogram signal of the patient. A heart sound sensor contacts the skin of the patient to measure a heart sound signal of the patient. A controlling unit obtains bio information including at least a heart rate from the electrocardiogram signal using the heart sound signal.

11. A bio signal measuring apparatus comprising:
-
a body operable to attach to a skin of a patient; an electrocardiogram measuring unit provided on the body and operable to attach to the skin of the patient to measure an electrocardiogram signal of the patient; a heart sound sensor disposed on the body and operable to contact the skin of the patient to measure a heart sound signal of the patient; a controlling unit disposed on the body and operable to output the electrocardiogram signal and the heart sound signal and to detect a window such that the window contains a first heart sound and a second heart sound of the heart sound signal; and a portable terminal operable to receive the electrocardiogram signal and the heart sound signal, and further operable to obtain bio information including at least a heart rate from the electrocardiogram signal with reference to the heart sound signal, wherein the bio information is obtained based on a result of determining whether an R peak of the electrocardiogram signal exists in the detected window. - View Dependent Claims (12, 13, 14, 15, 16)

17. A bio signal measuring for a bio signal measuring apparatus comprising:
-
a body operable to be attached to a skin of a patient; an electrocardiogram measuring unit disposed on the body and operable to be attached to the skin of the patient to measure an electrocardiogram signal of the patient; a heart sound sensor disposed on the body and operable to contact the skin of the patient to measure a heart sound signal of the patient; and a controlling unit disposed on the body and operable to obtain bio information including at least a heart rate from the electrocardiogram signal with reference to the heart sound signal and to detect a window such that the window contains a first heart sound and a second heart sound of the heart sound signal, wherein the bio information is obtained based on a result of determining whether an R peak of the electrocardiogram signal exists in the detected window, the method comprising; measuring the electrocardiogram signal and detecting the R peak from the electrocardiogram signal using a first threshold value; measuring the heart sound signal and determining the window from the heart sound signal; determining whether the R peak is detected in the window; and calculating the bio information from a plurality of R peaks which were previously detected if the R peak is detected in the window. - View Dependent Claims (18, 19, 20)
