HUMAN-BODY PRESSURE SENSING SYSTEM
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to sensing system, and more particularly to a human-body pressure sensing system.
2. Description of Related Art
In the medial domain, sensors are extensively used to collect and monitor various vital signs of patients so as to facilitate timely responsive actions. For example, different pressure sensors may be used to detect intra-body pressures at different parts of a patient.
To this end, capsule pressure sensors have been recognized as an effective means. However, existing capsule pressure sensors are designed for collecting absolute pressures in a human body, and are less accurate when used to monitor vital signs that can only be obtained through relative pressures (i.e. , the pressures in a human body with respective to the pressure of the ambient environment), such as the intra- abdominal pre ssure. Hence, there is a need for a pressure sensor capable of providing accurate relative pres sures of a patient.

In order to meet the aforementioned need, the present invention discloses a hum an -body pres sure sensing system, which i s able to accurately detect an intra-body ab solute pre ssure value and an intra-body relative pressure value related to a human body of a user, so as to provide medical staff with accurate and diverse data and to achieve monitoring of vital signs of patients .
In order to achieve the foregoing objectives, an embodiment of the present invention provides a human-body pre ssure sensing system, which comprises a hum an -body information sensing device, having a first wireless communication unit, a first pre ssure sensing unit, and an activating unit, in which the first pre ssure sensing unit senses an intra-body absolute pre ssure value inside a human body of a user, and outputs the intra-body absolute pre ssure value through the first wireless communication unit, so as that the activating unit controls the human-body information sensing device to start operation; and an off-body processing device, having a second wireless communication unit, a second pressure sensing unit, and a pressure calculating unit, in which the second wireless communication unit is in communication with the first wireless communication unit, and the second pressure sensing unit senses an ambient absolute pressure value, so that the pressure calculating unit receives the intra-body absolute pressure value and the ambient absolute pressure value, and determines an intra-body relative pressure value by calculating a difference between the intra-body absolute pressure value and the ambient absolute pressure value.
Thereby, the human-body information sensing device and the off-body processing device of the present invention can accurately detect the intra-body absolute pressure value and the intra-body relative pressure value inside a human body, and provide medical staff with accurate and diverse data, thereby achieving competent monitoring of vital signs of patients.

DETAILED DESCRIPTION OF THE INVENTION
The following preferred embodiments when read with the accompanying drawings are made to clearly exhibit the above- mentioned and other technical contents, features, and effects of the present invention. Through the exposition by means of the specific embodiments, people would further understand the technical means and effects the present invention adopts to achieve the above-indicated objectives. However, the accompanying drawings are intended for reference and illustration, but not to limit the present invention and are not made to scale .
Referring to FIG. 1 through FIG. 4 , in an embodiment of the present invention, a human-body pressure sensing system 100 comprise s a human-body information sensing device 10 and an off-body proce ssing device 20 that are in communication with each other. Therein, according to the embodiment of the pre sent invention, the human-body information sensing device 10 is in the form of a capsule for a user to swallow and ingest into his/her body, so that the human-body information sensing device 10 can detect various data inside the body of the user, and the off-body proces sing device 20 may be a wearable device such as a chest band or a waist band equipped with a smart device .
The human-body information sensing device 10 has a first wirele ss communication unit 10A , a first pressure sensing unit 10B, and an activating unit 10C that are coupled to each other. The first pressure sensing unit 10B sense s an intra-body absolute pressure value inside the human body, and the first wirele ss communication unit 10A outputs the intra-body absolute pres sure value to the off-body proces sing device 20. The activating unit 10C controls the human-body information sensing device 10 to start operation. Therein, as shown in FIG. 4, the human-body information sensing device 10 has a casing 11 , and the first pressure sensing unit 10B is such installed in the casing 11 that it is partially exposed outside the casing 11 , thereby maximizing measurement accuracy of the intra-body absolute pres sure value .
Additionally, in the embodiment of the pre sent invention, the activating unit 10C is a non-contact switch such as a magnetic switch or a microwave switch. In an example where the activating unit 10C is implemented using a magnetic switch, the user may make the activating unit 10C control the humanbody information sensing device 10 to start to operate by drawing a magnetic obj ect (e .g . , a magnet) close to the activating unit 10C . In the example of the present invention, the magnetic object has a magnetic flux density higher than 3 millitesla (mT) in order to activate the activating unit 10C . In another example where the activating unit 10C is implemented using a microwave switch, the off-body proce ssing device 20 is configured to emit a particular signal to the activating unit 10C to make the activating unit 10C control the human-body information sensing device 10 to start to operate . Since the activating unit 10C of the human-body information sensing device 10 is a non-contact switch, the user has the freedom to decide whether the human-body information sensing device 10 is to be activated outside or inside the human body, making use of the disclosed system more versatile and convenient.
As shown in FIG. 1 through FIG. 3, in the embodiment of the present invention, the hum an -body information sensing device 10 comprises an abnormity sensing unit 10D coupled to the first wireless communication unit 10A . The abnormity sensing unit 10D senses operation of the hum an -body information sensing device 10. When the abnormity sensing unit 10D d elects abnormal operation, an operational abnormity signal is outputted to the off-body processing device 20 through the first wireless communication unit 10A . Then the off-body processing device 20, according to the operational abnormity signal, displays an operational abnormity message to inform the user of the abnormity of the human-body information sensing device 10. In a preferred embodiment of the present invention, when detecting abnormal operation of the human-body information sensing device 10 , the abnormity sensing unit 10D first stops the human-body information sensing device 10, and re starts the human-body information sensing device 10 when the human-body information sensing device 10 recovers its normality. For example, the abnormity sensing unit 10D detects operation of the human-body information sensing device 10 by sensing abnormities in terms of temperature, voltage, and/or current (not limiting) .
As shown in FIG. 1 through FIG. 3, in the embodiment of the present invention, the hum an -body information sensing device 10 comprises a temperature sensing unit 10E and a protecting unit 10F that are coupled to the first wireless communication unit 10A . The temperature sensing unit 10E senses an intra-body temperature value inside the human body. The protecting unit 10F is preprogrammed with a temperature standard value and a time threshold . When the intra-body temperature value stays higher than the temperature standard value for a time period exceeding the time threshold, the protecting unit 10F controls the human-body information sensing device 10 to stop operating . For example, assuming that the temperature standard value is 36°C and the time threshold is 1 minute, when the intra-body temperature value has become 42°C (i.e ., being higher than the temperature standard value), and has stayed at this level for a period longer than 1 minute (being higher than the time threshold) , the protecting unit 10F shuts down all components in the human-body information sensing device 10 except for those vital ( such as the temperature sensing unit 10E), so as to protect the human-body information sensing device 10 from damage.
At this time, since the temperature sensing unit 10E remains working and continuously senses the intra-body temperature value, when it detects that the intra-body temperature value has become lower than the temperature standard value, the protecting unit 10F can restart the shut-off components in the human-body information sensing device 10, so as to restore the full ability of the human-body information sensing device 10 to collect various data in the human body.
