First Claim
Patent Images
1. A monitor of blood loss from a patient comprising the combination of a pad having a means for detecting blood presence and means for detecting wetness which indicates wetness from blood and non-blood fluids, and means associated with said pad for indicating the presence of blood and wetness from said detecting means, and providing an electrical signal for each indication, whereby the activation of all signals indicates profuse blood loss.

- 1. A monitor of blood loss from a patient comprising the combination of a pad having a means for detecting blood presence and means for detecting wetness which indicates wetness from blood and non-blood fluids, and means associated with said pad for indicating the presence of blood and wetness from said detecting means, and providing an electrical signal for each indication, whereby the activation of all signals indicates profuse blood loss.
- 12. A method for detecting profuse blood loss from a patient comprising providing means for measuring the presence of blood only, measuring the presence of blood at a predetermined position with said means, electrically signalling the presence of blood at said predetermined position, providing means for measuring wetness by all fluids at another predetermined position, measuring the presence of wetness with said wetness measuring means, electrically signalling the presence of wetness, and distinguishing blood wetness from other wetness from the combined signals so as to indicate profuse blood loss.

14. A method for detecting profuse blood loss from a patient and simultaneously distinquishing blood loss from other body fluids which comprises providing a fluid absorbent pad having at a first predetermined position means for measuring the pH of blood, measuring for the pH of blood at said first position, providing signal generating means in association with said blood pH measuring means, signalling the presence of blood with said signal generating means, providing wetness indicator means at a second predetermined position in said pad for indicating wetness and signal generating means in association with said wetness indicator means, signalling wetness at said second predetermined position, whereby the simultaneously activation of the signal means for blood and the wetness indicates profuse blood loss.

17. A method for detecting profuse blood loss from a patient and simultaneously distinguishing blood loss from other body fluids which comprises providing a fluid absorbent pad having at a first predetermined position means for measuring the pH of blood and signal generating means associated with said blood pH measuring means for signalling the presence of blood, providing wetness indicator means at a second predetermined position in said pad for indicating wetness and signal generating means associated with said wetness indicator means for signalling wetness, whereby the simultaneously activation of the signal means for blood and the wetness indicates profuse blood loss.
