Abstract: A venous needle dislodgment detection system for use with a blood access device during medical treatment is disclosed, comprising a medical blood access system in communication with a dislodgment sensing apparatus, the medical blood access system having a venous blood line; a first end of the venous blood line being coupled to the medical blood access system at a tubing connection point, and a second end of the venous blood line being coupled to the blood access device; the dislodgment sensing apparatus comprising a sensor positioned adjacent to the venous blood line and proximal to the tubing connection point, the dislodgment sensing apparatus being configured to generate a dislodgment signal in response to detecting a displacement force indicative of a potential dislodgment of the blood access device from the patient; and the medical blood access system being configured to automatically generate an alarm condition in response to receiving the dislodgment signal.

Abstract: A dialysis system includes: a blood filter; a dialysate pump connected to a dialysate portion of the blood filter; a blood pump connected to a blood portion of the blood filter, the blood pump including a diaphragm that is moved in cycles to pump the blood, the cycles having a flow period and a no-flow period; a patient access device in fluid communication with the blood portion of the blood filter, the no-flow period having a first characteristic of a property when the patient access device is lodged in a patient and a second characteristic of the property when the patient access device is dislodged from the patient; and a logic implementer configured to determine that the patient access device has been dislodged from the patient when the second characteristic of the parameter is detected.
