[0076] FIG. 3 illustrates an exemplary view of the proposed device to facilitate monitoring for monitoring and detecting blood loss, in accordance with an embodiment of the present disclosure.
[0077] As illustrated in FIG. 3, the device (100) can include a first set of sensors (102), a second set of sensors (104), a third set of sensors (106), a controller (108), and an alert unit (110). In an embodiment, the device (100) can facilitate determining blood loss associated with an entity and alerting the entity. The device (100) can enable monitoring the entity for blood loss and helps in determining heart rate of the entity. The device (100) can be wearable and adapted to be worn by the entity, where the wearable device can be any or a combination of band, strap, bracelet, and the likes.
[0078] In an illustrative embodiment, the wearable device can include a strap, and one or more sensors for detecting heart rate and the blood leakage. The one or more sensors can be based on PPG (Photoplethysmography), where the PPG sensor can facilitate measuring heart rate and heart rate variability. When heart beats, capillaries expand and contract based on changes in blood volume, the PPG sensor can emit set of light signals that reflect onto the skin of entity to accurately and continuously measure weak blood flow signals. The PPG sensor can make uses of low-intensity infrared green (IR) light such that upon passing the low- intensity infrared light through one or more tissues, the low intensity infrared light can be absorbed by bones and skin pigments, and changes in blood flow can be detected by the PPG sensor and intensity of the low intensity infrared green (IR) light changes.

In another illustrative embodiment, the device (100) can enable recognizing mood of the entity based on extracted speech signals with help of the controller (108), and the device (100) can help determining weight and body blood percentage associated with the entity. In yet another illustrative embodiment, velocity of gunshot and pressure on particular part of wound of the entity and the associated volume of blood loss can be calculated accordingly, and information can be stored on common server like cloud (302).
[0080] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0081] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, ` components, or steps that are not expressly referenced.
[0082] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
