Description
TECHNICAL FIELD

This disclosure relates to ultrasonic authentication for dialysis.


BACKGROUND

Dialysis is a treatment used to support a patient with insufficient renal function. The two principal dialysis methods are hemodialysis and peritoneal dialysis.


During hemodialysis (“HD”), the patient's blood is passed through a dialyzer of a dialysis machine while also passing a dialysis solution or dialysate through the dialyzer. A semi-permeable membrane in the dialyzer separates the blood from the dialysate within the dialyzer and allows diffusion and osmosis exchanges to take place between the dialysate and the blood stream. These exchanges across the membrane result in the removal of waste products, including solutes like urea and creatinine, from the blood. These exchanges also regulate the levels of other substances, such as sodium and water, in the blood. In this way, the dialysis machine acts as an artificial kidney for cleansing the blood. Generally, HD treatments require disposable items (e.g., tubing sets, fluids, dialyzers, etc) to be connected to the HD machine.


SUMMARY

In one aspect of the invention, a system for blood treatment includes a dialysis machine, and an ultrasonic authentication device connected to the dialysis machine. The ultrasonic authentication device is configured to scan a label using ultrasonic signals and to send identified label information to the dialysis machine.


In another aspect of the invention, a method of operating a dialysis system includes scanning a label with an ultrasonic authentication device connected to a dialysis machine, comparing the label information against stored information to determine whether the label corresponds to a required consumable for the dialysis machine, and instructing the user to proceed or halt setup based on the compared information. The ultrasonic authentication device is configured to scan the label using ultrasonic signals and to send identified label information to the dialysis machine.


Implementations can include one or more of the following features.


In some implementations, the label information includes a lot number, a material description, a sku, an expiration date, a size, and/or a concentration.


In certain implementations, the label information is positioned on a clear label.


In some implementations, the system further includes a consumable having a label configured to be scanned by the ultrasonic authentication device.


In certain implementations, the consumable is a saline bag, a dialyzer, a tubing set, and/or a drug.


In some implementations, the label is positioned on a consumable being installed on the dialysis machine.


Embodiments can include one or more of the following advantages.


The ultrasonic authentication devices described herein can help to ensure that a correct disposable (e.g., solution, drug, fluid line set) is connected to the hemodialysis device. This reduces patient risk caused by user error, expired materials, or incompatible disposables. In addition, the ultrasonic authentication devices described herein are also compatible with various labeling applications (e.g., clear labels, paper labels, and/or solid foil/metal labels.) This versatility helps to provide a user-friendly experience when authenticating labels and helps to reduce the risk of errors by the authentication device.


The details of one or more implementations are set forth in the accompanying drawings and the description below. Other aspects, features, and advantages will be apparent from the description and drawings, and from the claims.





DESCRIPTION OF DRAWINGS


FIG. 1 shows a blood treatment system including a blood treatment machine and an ultrasonic authentication device where the blood treatment machine is configured to identify label information.



FIG. 2 shows the ultrasonic authentication device of FIG. 1.



FIG. 3 shows a method of using an ultrasonic identification device in preparation for a dialysis treatment.





DETAILED DESCRIPTION

In certain aspects, an ultrasonic authentication device can be used to identify information from labels on items used in a dialysis treatment. These items can removeable or connectable to a blood treatment device (e.g., disposables, accessories, fluids, and/or drugs.)



FIG. 1 shows a blood treatment system 100 that includes a blood treatment machine (e.g., hemodialysis machine 102) and an ultrasonic authentication device 104, connected to hemodialysis machine 102. The ultrasonic authentication device 104 includes an ultrasonic signal transmitter 106 configured to send ultrasonic signals. An ultrasonic signal receiver 108 is configured to receive reflected ultrasonic signals.


In FIG. 1, the hemodialysis machine 102 and ultrasonic authentication device 104 are connected electronically. A user interface 132 is mounted on or integrated in the hemodialysis machine 102 and is operably controlled by a controller (e.g., a controller 202 shown in FIG. 2) of the hemodialysis machine 102. The user interface 132 can be configured to display information related to the labeling information received by the ultrasonic signal receiver 108. This labeling information can include information related to the function or source of the item (e.g., lot number, description, sku, expiration date, size, and/or concentration.)


In operation, a blood pump 122 of the hemodialysis machine 102 pumps blood through an extracorporeal circuit 117 connected to the hemodialysis machine 102. More specifically, the blood pump 122 draws blood out of a patient 101 via an arterial patient line 118 and forces the blood through a blood chamber of a dialyzer 112. As the blood passes through the blood chamber of dialyzer 112, dialysate passes through a dialysate chamber of the dialyzer 112, so that the blood is cleared of toxins. The cleansed blood then flows through a venous air trap 120 where any air in the blood is collected and is returned to the patient via a venous patient line 110. A saline bag 107 is connected to the venous air trap 120 for introducing saline into the cleansed blood.


In some cases, before identifying the label information, the controller 202 of hemodialysis machine 102 will generate a notification to notify the operator that label information is required. The notification may be visual, auditory, and/or vibrational.


After the ultrasonic authentication is completed, label information is transmitted from the ultrasonic authentication device 104 to hemodialysis machine 102 via the ultrasonic signal transmitter 106 and the ultrasonic signal receiver 108. The ultrasonic signal receiver 108 receives the label information and user interface 132 then optionally displays the label information, an error, and/or further instructions to the user.



FIG. 2 is a schematic illustration of the ultrasonic authentication device 104 including the ultrasonic signal transmitter 106 and the ultrasonic signal receiver 108. The saline bag 107 is an exemplary disposable and includes a label 109. The label 109 can be formed from different labeling applications (e.g., clear labels, paper labels, and/or solid foil/metal labels.) In this example, a user places the bag before the ultrasonic authentication device 104 before use. The ultrasonic authentication device 104 transmits high-frequency sound waves 204 directed at the label 109 and receives reflected waves 206. Based on the reflected waves 206 the controller 202 identifies labeling information from the label 109. In some cases, the received labeling information is displayed to the user on the user interface 132. In other cases, the received labeling information is first compared against expected information. If the information matches expected or acceptable parameters, the treatment or set up is allowed to progress. If the information does not match, the user can be shown an error (e.g., a request to rescan, the reason for rejection, and/or a request to scan a new saline bag.)



FIG. 3 is a flow chart illustrating a method 300 using an ultrasonic identification device in preparation for a dialysis treatment. To prepare for treatment, the hemodialysis machine 102 notifies 304 the user (e.g., via the user interface 132) that authentication is required before connecting a saline bag. Then, the label of the saline bag is scanned 306 by the ultrasonic authentication device when the user places the label near the ultrasonic authentication device. A controller of the HD machine then compares 308 the received label information with expected information. If the label information matches the expected information, the user is instructed to proceed 310 with machine set up. If the information does not match, the user is shown an error (e.g., a request to rescan, the reason for rejection, and/or a request to scan a new saline bag). While FIG. 3 illustrates a method for verifying label information of a saline bag, other connectable components of a dialysis system could be similarly verified.


Alternative Implementations


The examples described herein can be implemented in a variety of ways without departing from the scope of the specification.


While the authentication device 104 is generally shown as part of the hemodialysis machine 102, in some cases, the authentication device could be detachable or connectable to a medical device.


While the saline bag 107 and the label 109 are generally described, labels for other removable components could also be used. For example, a label on the extracorporeal circuit or the dialyzer could be authenticated using the authentication device 104.


Elements of different implementations described herein may be combined to form other implementations not specifically set forth above. Elements may be left out of the structures described herein without adversely affecting their operation. Furthermore, various separate elements may be combined into one or more individual elements to perform the functions described herein.


Various embodiments discussed herein may be combined with each other in appropriate combinations in connection with the system described herein. Additionally, in some instances, the order of steps in a method may be modified, where appropriate. Further, various aspects of the systems described herein may be implemented using software, hardware, a combination of software and hardware and/or other computer-implemented modules or devices having the described features and performing the described functions.


Software implementations of aspects of the system described herein may include executable code that is stored in a computer-readable medium and executed by one or more processors. The computer-readable medium may include volatile memory and/or non-volatile memory, and may include, for example, a computer hard drive, ROM, RAM, flash memory, portable computer storage media such as a CD-ROM, a DVD-ROM, a flash drive and/or other drive with, for example, a universal serial bus (USB) interface, and/or any other appropriate tangible or non-transitory computer-readable medium or computer memory on which executable code may be stored and executed by a processor.
