Description

FIELD OF THE INVENTION

The invention, in some embodiments, relates to the field of controlling or authenticating or registering or tracking infusion, and more particularly, but not exclusively, to an infusion tracker configured to assist in controlling or authenticating or registering or tracking infusion, and to related methods.

BACKGROUND OF THE INVENTION

Intravenous administration of medications or blood transfusion is one of the most common medical therapeutic endeavors. It has been estimated that in US hospitals alone there may be as many as 1 billion intravenous infusions annually. The transfusion of blood products amounts to about an additional 15 million in the US. In addition, intravenous drugs are also administered in outpatient clinics and home care treatments, both hospital-affiliated and free standing, in nursing homes and in physicians' offices. Finally there is an exciting growing industry of home infusions which alleviates the health care system from costly and sometimes hazardous hospitalizations. At home care treatments there is no confidence if the patient follows exactly the physician instructions and prescription. Thus, considerable activity associated with intravenous administration of medications or blood transfusion is carried out in locations or under constraints that preclude or diminish direct control and/or authentication of details associated with such activity.

SUMMARY OF THE INVENTION

As discussed above, patients receiving intravenous infusions at a distance are in a risk of receiving the wrong medication, or receiving their medications at the wrong time, in the wrong order, or not at all. The current invention creates an electronic monitoring system so that caregivers know in real time what is happening with all their patients who are supposed to receive intravenous medications. In some embodiments the system may alert caregivers when there is non-compliance with doctor's orders and can communicate directly with caregivers to assure appropriate and safe treatment.

According to an aspect of some embodiments there is provided an IV administration set with a new compliance activator. The activator has two parts, one is the base unit including a special firmly groove to hold a standard infusion line, and the second part is the activator cover holding a memory tag like NFC or RFID or similar tags in a special location containing all the necessary details regarding the treatment, the patient and the caregiver. The activator unit is located on the infusion line in any place by a one way connector, the activator is placed on the line in the pharmacy during the bag filling, and according the type of medication filled in the bag. By scanning the memory tag by an HHD, smartphone or another suited device with a dedicated application all the treatment details will be sent in real time mode to the backend software by wireless communication, comparing with the physician order entered before treatment should start. If even one of the compared details is wrong the system sends a hazard message to all point of care locations including the caregiver, the physician and the nurse station.

According to an aspect of some embodiments there is provided an infusion tracker comprising a base and a cover configured to be assembled onto the base. The infusion tracker further comprises a memory tag, attached to one of the base and the cover and configured to store data and operable to wirelessly release stored data in a format readable by a processor-controlled device or to activate an application software.

The infusion tracker has at least a first state, and a second assembled state in which the cover is assembled onto the base. The infusion tracker may be moved from the first state to the second assembled state by manually pressing the cover towards the base, and the infusion tracker may not be moved from the second assembled state to the first state by pressing the cover towards the base nor by releasing a pressure therefrom.

The infusion tracker, in the second assembled state is further configured to enclose a portion of an infusion line between two ends of the portion, the portion being enclosed substantially between the base and the cover. Fluid communication substantially exists between the two ends of the portion when the infusion tracker is in the second assembled state.

According to an aspect of some embodiments there is further provided a method of controlling and/or authenticating and/or registering an infusion event, the method comprises:

providing an infusion tracker according to the teachings herein, wherein the memory tag stores personal data of a patient and/or data of a care giver, and/or data of a drug to be infused or blood product to be transfused , and/or data of an application activated procedure;

The base 18 has 4 snaps 19. By pressing the cover to the base, the snaps 18 enter to a special groove in the cover without any capability to open it after closing—this is a one way movement.

The assembly of infusion tracker 10 may be performed in the pharmacy, after filling an infusion fluid containing bag (not shown) with a medication and labeling. Infusion tracker 10 is assembled on the line as depicted in FIG. 2A. In this option there is no clinical info on the tag. The bag with the medication and with infusion tracker 10 is ready for sending to the patient.

FIGS. 3A-3D and FIGS. 4A-4B depict schematically a process of controlling infusion using Infusion tracker 10. After connecting the bag to the patient by the infusion line 16, a care giver may scan the memory tag 12 on infusion tracker 10 by a smartphone 20 with a dedicated application. By scanning the infusion tracker 10 the application starts working and sends a request to a backend station 24 (FIG. 3C) wirelessly for the treatment details for this patient. The treatment details are received from the back office station 24 and the care giver is asked to scan the bag barcode or NFC tag by a message 22. By scanning the tag the message on the screen (FIGS. 4A, 4B) asks for scanning the barcode bag. The care giver scans the bag barcode (FIG. 4C) and if all the details comparing the physician order are correct, the smartphone sends to the back office confirmation and start monitoring the procedure. According to some embodiments, after completing the treatment the care giver scans the tag again thereby activating sending to the backend an indication that treatment has completed and can throw away the empty set including the infusion tracker. Infusion tracker 10 is a disposable unit.

FIGS. 5A and 5B schematically depict an embodiment of an infusion tracker 30 according to an aspect of some embodiments. In FIG. 5A infusion tracker 30 is assembled onto an infusion line 16.
