Wearable monitor for the early detection of internal bleeding events after cardiac catheterization

A monitor system configured for the detection of bleeding events in tissue comprising:

• a) a wearable monitor comprising:
• i) a length axis;
• ii) an interface side;
• iii) a monitoring array comprising a plurality of transducers;
• wherein the monitoring array includes a first four-point probe comprising:
• two transducers of the plurality of transducers, each functioning as emitter devices that are electrodes to input an emitter input that is an electrical signal into said tissue,
• two transducers of the plurality of transducers, each functioning as detector devices that are electrodes configured to detect a detection signal from the said emitter input of the first four-point probe;
• wherein the two emitter devices are configured an emitter offset distance from each other along a first interrogation axis, and
• b) an attachment component configured to detachably attach the monitor to a person with the interface side configured to face said tissue;
• c) a controller comprising a computer;
• wherein the controller controls activating and deactivating said emitter devices and activating and deactivating said detector devices;
• wherein the controller receives said detection signal;
• and
• d) an alert system comprising an alert device to produce said alert;
• e) a pump and a bladder that is configured to be inflated by said pump if a bleeding event is detected by a change in the detection signal of a diagnostic test;
• wherein the controller initiates said alert on said alert device when a change in the detection signal is above a threshold value.
