Abstract

A dialysis machine comprising: a first sensor for detecting motion of a patient; a second sensor for detecting a health condition of the patient; a processing module for: controlling dialysis functions of a dialysis treatment; receiving information related to a status of the dialysis treatment in which toxins are removed from blood of the patient; receiving, from the first sensor, information related to the motion of the patient; receiving, from the second sensor, information related to the health condition of the patient; and identifying an emergency condition based at least in part on the information related to the motion of the patient, the information related to the health condition of the patient, and the information related to the status of the dialysis treatment; and a transceiver for: in response to identifying an emergency condition, sending a notification that includes patient information to one or more remote entities.

receiving, from the second sensor, information related to the health condition of the patient;

identifying a potential emergency condition based at least in part on the determination that the patient has not moved for the predetermined amount of time; and

identifying an emergency condition based at least in part on the determination that the patient has not moved for the predetermined amount of time, the information related to the health condition of the patient, and the information related to the status of the dialysis treatment;

a first alert mechanism for;

generating an alert directed at the patient indicating that the potential emergency condition has been identified; and

receiving, from the patient, an input indicating that the potential emergency condition is not an emergency condition, wherein the identifying the emergency condition includes identifying the potential emergency condition as an emergency condition because an input was not received;

a universal serial bus (USB) data communications interface comprising;

a USB port on the dialysis machine that interfaces with a portable USB memory device that includes a second alert mechanism configured to generate an alert directed at an emergency responder, the alert for informing the emergency responder that the portable USB memory device contains patient information that is relevant to an emergency condition of the patient, and

a USB interface control system for managing download of the patient information to the portable USB memory device in response to the identification of the emergency condition; and

a transceiver for;

in response to identifying the emergency condition, sending a notification that includes patient information to one or more remote entities.

2. The dialysis system of claim 1, wherein the dialysis machine comprises:

a dialysate cassette configured to be fluidly connected to one or more dialysate containers by one or more dialysate container lines; and

a dialysate pump for;

pumping dialysate from one or more of the dialysate containers, through the dialysate cassette, through a patient line, to an abdomen of the patient; and

drawing spent dialysate from the abdomen of the patient, through a drain line, through the dialysate cassette, to a drain, wherein the spent dialysate includes toxins that are removed from the blood of the patient.

3. The dialysis system of claim 1, wherein the dialysis machine comprises:

a dialysate pump for pumping dialysate through a first portion of a dialyzer; and

a blood pump for drawing blood from the patient through a second portion of the dialyzer, wherein the dialyzer is configured to remove toxins from the blood of the patient and collect the toxins in the dialysate.

4. The dialysis system of claim 1, wherein the second sensor is a blood pressure sensor and the information related to the health condition of the patient is blood pressure information.

5. The dialysis system of claim 1, wherein the second sensor is a heart rate sensor and the information related to the health condition of the patient is heart rate information.

6. The dialysis system of claim 1, wherein the second sensor is a moisture sensor.

7. The dialysis system of claim 6, wherein the moisture sensor is for detecting whether a needle has been dislodged from the patient.

8. The dialysis system of claim 1, comprising a device that is in wireless communication with the dialysis machine, the device including the alert mechanism and a button that, when engaged by the patient, indicates that the potential emergency condition is not an emergency condition.

9. The dialysis system of claim 8, wherein the device is configured to wirelessly receive patient information from the dialysis machine.
