Description

Vital signal detection device for patient safety monitoring The present invention relates to a biosignal detection device for patient safety monitoring, and more specifically, to a biosignal detection device for patient safety monitoring with an improved structure that enables real-time monitoring of patient safety without disturbing the patient's sleep, even in environments where management by medical staff or guardians is relatively reduced, such as during a patient's sleep state. Hospitalized patients receive stable treatment through the management of medical staff and guardians. However, when patients enter a sleep state during the night, such observation and management are relatively reduced, which poses a risk that a rapid deterioration in the patient's condition may not be immediately recognized and a response may be delayed. In particular, since this problem is even more severe in general wards where intensive monitoring is not required, unlike in intensive care units, there is a need for the development of technology capable of monitoring patient safety by detecting vital signs in real time, even in environments where medical staff supervision is inevitably reduced due to conditions, such as during a patient's sleep. FIG. 1 is a perspective view of a biosignal detection device for patient safety monitoring according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is a diagram showing the usage state of an embodiment of the present invention. FIG. 4 is a block diagram relating to the configuration of an embodiment of the present invention. In order to clarify the understanding of the present invention in the following description, descriptions of known technologies regarding the features of the present invention will be omitted. The following embodiments are detailed descriptions to aid in understanding the present invention and are not intended to limit the scope of the rights of the present invention. Accordingly, equivalent inventions that perform the same function as the present invention will also fall within the scope of the rights of the present invention. Furthermore, in the following description, identical identification symbols denote identical configurations, and unnecessary redundant descriptions and descriptions of known technologies are omitted. Additionally, descriptions of each embodiment of the present invention below that overlap with the description of the technology forming the background of the invention are also omitted. Hereinafter, a biosignal detection device for patient safety monitoring according to an embodiment of the present invention will be described in detail with reference to the attached drawings. FIG. 1 is a perspective view of a biosignal detection device for patient safety monitoring according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1, FIG. 3 is a diagram showing the usage state of an embodiment of the present invention, and FIG. 4 is a block diagram regarding the configuration of an embodiment of the present invention. As illustrated in FIGS. 1 and 2, a biosignal detection device for patient safety monitoring according to an embodiment of the present invention is designed to monitor the safety of a patient in real time by detecting the patient's arterial heartbeat even in environments where medical staff or guardians may be negligent, such as in the patient's life condition, and comprises a wearable band (1) and an arterial heartbeat detection unit (2). The above-mentioned wearing band (1) is worn detachably on a body part where the patient's arterial pulsation is detected, and it is preferable to make it in the form of a thin band made of a soft and elastic material (a material that can be bent as shown by the dotted line in FIG. 2 and then restored as shown by the solid line in FIG. 2, e.g., silicone) so as not to disturb the patient's sleep state. The above arterial pulse detection unit (2) is coupled to a position corresponding to the body part where the arterial pulse is detected on the wearable band (1), and, as clearly illustrated in FIG. 4, comprises a stethoscope (21), a microphone (22), and a control device (25). The above-mentioned stethoscope (21) is used in a widely known stethoscope and plays a role in acquiring sound data regarding the arterial pulsation even in environments where medical staff or caregivers provide care, such as when the patient is in a sleeping state, thereby enabling smooth detection of the patient's vital signs. The above microphone (22) serves to convert the sound signal obtained by the stethoscope (21) into an electrical signal of the same waveform. Unlike conventional technology that employs a short-range manual diagnostic method of obtaining biosignals by contacting a stethoscope to a patient's body part, this enables remote automatic diagnosis by utilizing digital data.
