Definitions
- the present invention relates to the field of measurement of vital signs of a subject. It particularly relates measurement of vital signs selected from temperature, pulse rate, respiratory rate, blood pressure, dissolved blood oxygen, and electrocardiogram
- Measurement of vital signs is an important part of patient care, whether at home or at hospitals.
- Vital signs that are measured and monitored include temperature, blood pressure, pulse rate, respiratory rate, dissolved blood oxygen and electrocardiogram. It is particularly important to have patient data recorded correctly whilst avoiding human errors in writing/recording.
- the healthcare workers are busy and under pressure and there are chances of human errors that can have negative impact on recovery of a patient.
- US20080058614A1 provides system for measuring vital signs from multiple patients, typically in an in-hospital setting.
- the system features a body-worn vital sign monitor that includes: i) a sensor configured as a patch that measures electrical and optical signals from a patient; ii) a controller featuring a microprocessor that receives and processes the electrical and optical signals to determine the patient's vital sign information, including blood pressure; and iii) a first short-range wireless component that wirelessly transmits a packet comprising the vital sign information to an external receiver.
- a portable, wireless computer e.g., a PDA, cellular telephone, or a laptop computer
- the wireless computer includes: i) a second short-range wireless component that receives the vital sign information and displays it; and ii) a long-range wireless transmitter that transmits the vital sign information over a wireless network.
- the system also includes an Internet-based system that receives the vital sign information from the wireless network, and avails this to medical professionals through an in-hospital information system. This reference does not teach that body worn monitor (probe unit) and the wireless monitor (main unit) are detachably attachable.
- US2019090741 (NohonKohden Corp, 2019) describes a vital signs sensor includes an identifier storage device that stores an identifier of a subject, and a signal processing device that acquires a vital sign from the subject, and that wirelessly transmits the vital sign and the identifier that is stored in the identifier storage device, with correlating the vital sign with the identifier, wherein the identifier storage device has a structure where the identifier storage device is attachable to and detachable from the signal processing device.
- the vital sign acquiring section (20) is not detachably attachable to the signal processing section (21).
- US10213159B2 provides a body-worn vital sign monitor that measures a patient's vital signs (e.g. blood pressure, Sp02, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling) and posture (upright, supine).
- the monitor processes this information to minimize corruption of the vital signs and associated alarms/alerts by motion-related artifacts.
- It also features a graphical user interface (GUI) rendered on a touchpanel display that facilitates a number of features to simplify and improve patient monitoring and safety in both the hospital and home.
- GUI graphical user interface
- US6416471B1 (CLEARPATH PARTNERS LLC, 2002) describes a system and method for monitoring vital signs and capturing data from a patient remotely using radiotelemetry techniques.
- the system is characterized by a cordless, disposable sensor band with sensors form measuring full waveform ECG, full waveform respiration, skin temperature, and motion, and transmission circuitry for the detection and transmission of vital signs data of the patient.
- a small signal transfer unit that can either be worn by the patient, e.g., on his or her belt, or positioned nearby receives data from the sensor band, which it then forwards by e.g., radio transmission to a base station that can be located up to 60 meters away.
- the base station receives data transmissions from the signal transfer unit and is designed to connect to conventional phone lines for transferring the collected data to a remote monitoring station.
- the base station may also capture additional clinical data, such as blood pressure data, and to perform data checks.
- Patient safety is enhanced by the ability of the base station to compare clinical data, e.g., ECG, against given profiles and to mark events when appropriate or when the base station is programmed to do so. Such events are indicated to the physician and could be indicated to the patient by reverse transmission to the signal transfer unit.
- a remote monitoring station allows the presentation and review of data (including events) forwarded by the sensor band.
- ECG analysis software and a user-friendly graphical user interface are provided to remotely analyze the transmitted data and to permit system maintenance and upkeep.
- the system of the invention has useful application to the collection of patient clinical data during drug trials and medical testing for regulatory approvals as well as management of patients with chronic diseases.
- US20060155589A1 (Welch Allynlnc, 2006) describes a portable vital signs measurement instrument, systems and methods that provide a variety of measurement capabilities, including blood pressure, temperature, pulse oximetry, and other indications of patient status.
- the instrument, systems and methods include the ability to communicate wirelessly, for example using Wi-Fi (IEEE 802.1 IB), with a server, so that information can be entered easily, securely and reliably into a medical database system accessible by way of the server.
- Wi-Fi IEEE 802.1 IB
- the systems and methods provide for the instrument to initiate a communication session by attempting to discover a server access point in its vicinity.
