Abstract

The invention is a method and system for monitoring, documenting and assisting with the manual preparation and/or administration of medications. The invention accomplishes these goals via constant surveillance of the preparation/administration process using one or more digital cameras and software and hardware that processes the images and compares data from the processed images with information relative to the patient, to the drug components and composition of the medicament, and to non-drug items needed in the preparation that the system automatically or manually retrieves from various sources, e.g. internal or external data banks, from the technician/pharmacist, or by scanning the prescription.

First claim

1 . A method for monitoring, documenting and assisting with the manual preparation and/or administration of medications, said method comprising:
a) using at least one digital camera to provide constant surveillance of the preparation/administration process; b) providing software adapted to perform image processing of images acquired by said at least one digital camera and to compare, in real time, data extracted from the processed images to information relative to one or more of a patient, drug components and composition of said medication, and non-drug items needed in the preparation, wherein said data is automatically or manually retrieved from various sources; and c) providing dedicated software algorithms that are adapted to act as an interactive assistant guiding and/or supervising a producer through each step of a specific preparation process

2 . The method of claim 1 , comprising providing software adapted to compile complete documentation of the medication preparation process in the form of visual and data archives of the preparation steps, in which every step in the preparation process is documented and indexed.

3 . The method of claim 1 , comprising a stage comprised of general steps that are followed for filling any type of prescription; wherein the algorithms in the software are adapted to verify the correct match of a prescription to a patient and to his/her medical condition and to supervise or guide a producer when selecting the prescribed drugs and equipment needed for the preparation process.

4 . The method of claim 1 , wherein a visual or aural warning alerts the producer, if an error is detected at any stage of the preparation or administration process.

5 . The method of claim 3 , wherein the images and data that are processed by the software are saved together with the parameters of the objects visible in said images that the software has deduced for them.

6 . The method of claim 1 , wherein barcode recognition, QR code recognition, OCR (Optical Character Recognition), and additional pattern recognition algorithms are used to supply data from the images.

7 . The method of claim 1 , wherein images of a syringe are analyzed to determine at least one of the following:
a) the type and size of said syringe; b) whether said syringe is filled with air or transparent liquid; c) whether bubbles are present in the liquid in said syringe; d) to determine the volume of said bubbles; and e) to measure the volume of liquid in said syringe by recognizing the piston of said syringe and a reference line on the barrel of said syringe and measuring the distance between them.

8 . A system for monitoring, documenting and assisting with the manual preparation and/or administration of medications, said system comprising:
a) at least one digital camera adapted to provide constant surveillance of the preparation/administration process; b) a processor unit comprising:
i) software adapted to perform image processing of images acquired by said at least one digital camera and to compare, in real time, data extracted from the processed images to information relative to one or more of a patient, drug components and composition of said medication, and non-drug items needed in the preparation, wherein said data is automatically or manually retrieved from various sources;
ii) dedicated software algorithms that are adapted to act as an interactive assistant guiding and/or supervising a producer through each step of a specific preparation process; and
c) a display screen adapted to serve as an interface between said producer and the software of said system.

9 . The system of claim 8 , wherein the processor unit additionally comprises software adapted to compile complete documentation of the medication preparation process in the form of visual and data archives of the preparation steps, in which every step in the preparation process is documented and indexed.

10 . The system of claim 8 , adapted to produce a visual or aural warning to alert the producer if an error is detected at any stage of the preparation or administration process.

11 . The system of claim 8 , wherein the image processing software is adapted to use barcode recognition, QR code recognition, OCR (Optical Character Recognition), and additional pattern recognition algorithms to supply data from the images.

12 . The system of claim 8 , wherein the image processing software is adapted to process images of a syringe taken by the at least one digital camera in order to determine at least one of the following:
a) the type and size of said syringe; b) whether said syringe is filled with air or transparent liquid; c) whether bubbles are present in the liquid in said syringe; d) to determine the volume of said bubbles; and e) to measure the volume of liquid in said syringe by recognizing the piston of said syringe and a reference line on the barrel of said syringe and measuring the distance between them.

13 . The system of claim 12 , comprising an illuminated surface on which a syringe can be placed.

14 . The system of claim 13 , wherein the source of illumination is polarized.

15 . The system of claim 8 , wherein said system is adapted to be portable.
