DETAILED DESCRIPTION OF THE PREFERRED EXAMPLES

[0021] FIG. I is an example display formed on a display device 100 in one embodiment. The display is shown comprising, pattern 101 of clusters 1 1 OA- H ON. Each cluster is shown comprising set of segments 12 OA- 120K. [0022] Each cluster J 1 OA- 1 ION represents set of vitals of a particular patient (distinctly different from other). The pattern 101 represents the arrangement of the clusters 11 OA- 1 ION relating a patient association to one or more parameters. For example the association may be in terms of patient's physical location, criticality, importance, time relation, doctor, nurse, etc.

[0023] Thus, in one embodiment each row in the pattern 101 may represent the respective floor, block, ward of a hospital. Alternatively, each row may also represent different hospitals. As a further alternative, each row may also represent a doctor or a nurse.

[0024] The segments 120A- I20K in each clusters represents a vitals of the patient. Thus, "K" number of vitals of the patients is presented in one cluster to simultaneously scc/vicw the vitals of the patients. Such simultaneous viewing multiple vitals of multiple patients in accordance with pattern 101 enable quick and faster attention provided to patient's needs at least when managed and monitored cn masse.

[0025] FIG. 2 illustrates an example cluster 1 10A of a patient. As shown there the cluster is comprised of vitals 210A-2I0D. Each vital 210A-210D respectively represents skin temperature, heart rate, oxygen saturation, and the pain level for example. The vitals may be arranged (within each cluster) in a circular, triangular or any other meaningful formation that provide visible distinction of each vitals. In one embodiment, the position of the vitals within the clusters indicates the type of vitals. The value of the vitals may be represented in the grey level and or color code. For example, in case of color coding, higher criticality may be represented in red tones and low criticality may be represented in green tone. Thus, providing the comprehensive visible display of vitals of plurality of patients. Alternatively, in case of grey level, higher grey scale may represent the high criticality while lower grey scale may represent the low criticality.

[0026] FIG. 3 is an example array of clusters of vitals of patients associated with a doctor. The array is shown comprising patients 3 I0A-3 I0E on row 301 , and 3 I 0F-3 IOJ on row 302 associated to a doctor 320 from group of doctors 340. The row 301 and 302 respectively represents hospital 1 and hospital 2 in one embodiment and in an alternate embodiment, the row 301 and 302 represents different ward, floor or block within the hospital. As shown there, vitals 350A-3S0C of each patient 3 I0A-3 I0J is clustered into rectangular box for simultaneous viewing. The vitals 3SOA-3S0C are colors coded to indicate the criticality. The vital type is indicated with the respective graphics 371 , 372, and 373. For example, as shown there the skin temperature is indicated with the graphical- thermometer 371 , Oxygen saturation is indicated with the graphical blood droplet 372, and heart beat count is indicated with the graphical curve 373. . Accordingly the user is able to quickly read and associate the vitals of patients en . masse and provide attention and service accordingly. In one embodiment, an effective warning score is determined from the plurality of vitals in each cluster to present an effective warning score view of a plurality of patients. The effective warning may provide an early warning. As result, a single representation in terms of varying grey scale or differentiating colors are provided to represent the overall/effective/early warning or criticality level of the patient.

[0027] FIG. 4 is an example effective/early warning score view of plurality of patients in one embodiment. The array of patients 410 is represented by rectangular icons 450 (or any other shape). In that, each color 401- 404 indicates the range of the vitals that is calculated/determined based on a predetermined early warning score values. The color Green 401 indicates "Normal", the color Orange 402 indicates "abnormal" and the color Red 403 indicates that the patient is critical. The icon in the color grey 404 represents that the wearable or vital measurement device is not connected/enabled, for example. Similarly, other quick effective warning views indicating the different levels of attention may be deployed. For example, audio beepers, flickering of Icons and such other audio visual effects may be incorporated to represent the effective warning score level. The manner in which the display device displays several details from top level effective warning view to the particular vital details of a desired patient is further described below.

[0028] In one embodiment the display device navigates from one view to another through filters and selections.

The wearable device 710 is deployed with sensors to sense and measure the vitals such as skin temperature, heart rate, BP, blood oxygen lcvel/oxygcn saturation etc., when worn. The sensor is deployed on the wearable device to make appropriate contact with the body to measure the vitals. The wearable device comprises panic and emergency button for the patient to draw attention in the event of any emergency. In one embodiment, the wearable device communicates with the mobile device 720 and transfers the vital to the mobile device at a regular interval.

[0038] In one embodiment, the wearable device is shown comprising the oxygen saturation (SP02) sensor clip 7 I S interfaced through the SPI cable 716. Accordingly, the clip may be removed when not needed and when the SP02 needs to be monitored, the clip may be attached to the finger flexible through the extended cable 716. The wearable device detects the correct position of the finger on the clip to eliminate any sensor reading error.

[0039]-' In one embodiment, the wearable device stores the data measured when ^'the connectivity to the network or to the associated mobile device is not available. The stored vitals are transferred to the mobile device when (he connection is established- with the mobile device. [0040] The mobile device 720 receives the vitals from the wearable device and displays the vitals in a suitable format. Thus, mobile users may quickly determine the health condition of the corresponding one or more patient locally without having to connect server. Thus, patient may see, monitor, maintain the health- and manage the wearable device through the mobile device. In one embodiment, mobile device may also provide a user interface to a patient to feed in other information such as pain level etc. The manner in which the mobile device may display health information for the use of patient and for local use by doctors/nurse or caretaker is further described below.

As shown in FIG. 9E, the mobile device 720 display warning to indicate the finger is not placed accurately in the clip 715 and enable the patient to place the finger accurately for retaking the measurement. IN figure 9E, mobile device 720 display messages indicating the measurement is being made and guide the patient to keep the hand immobile for accurate reading. Accordingly, the wearable device and mobile device operate interactively ιο take accurate PS02 reading. FIG.9F illustrates the manner in which the mobile device retrieves the data stored on the wearable device when the connection to the mobile device 720 is lost. The mobile device presents the display as-shown to indicate that the vitals data that are stored in the wearable device is being updated/ restored. Mobile device may further save vitals for reference and upload the vital- to the server as and when the connection is established with the server.

[0047] In operation, Wearable device upon user input (reset), device is initialized. Embedded software is downloaded and executed by the processor 1070. The processor 1070 loads the BLE protocol s/w to the BLE device. Through mobile APP S/W interface user configuration is sent to the processor 1070 via BLE interface. The processor 1070 shuts down all devices until it is lime for next measurement. When it is due for measurement, user is alerted for immobilizing the arm. H/W enables each peripheral device, takes measurement, aggregates data into user data structure and sent to mobile device via BLE. When the user wants to force a measurement, mobile device sends data collection intimation to wearable device. In other limes, each of the hardware sub modules are kept in low power mode for reducing the overall power consumption during idle time.
