Medical Device With Information Reader

Patent No. US11289180 (titled "Medical Device With Information Reader") was filed by Carefusion 303 Inc on Aug 12, 2021.

What is this patent about?

’180 is related to the field of medical device integration, specifically addressing the problem of associating barcode scanners or other information readers with medical devices like infusion pumps in a hospital setting. The background highlights the limitations of permanently attaching scanners to devices and the inflexibility of existing barcode medication administration (BCMA) systems, where scanners primarily interact with a centralized system rather than directly with the medical devices themselves.

The underlying idea behind ’180 is to enable a more flexible and direct communication pathway between information readers and medical devices. This is achieved by having the medical device display a scannable tag (e.g., a barcode) containing information that uniquely identifies the device. When a scanner reads this tag, it establishes an association with that specific medical device, allowing subsequent scans (like medication barcodes) to be routed directly to it.

The claims of ’180 focus on an infusion pump (or system) equipped with a display that renders a scannable tag. This tag, when scanned, provides the information reader with the necessary data to uniquely identify the infusion pump. The infusion pump is then configured to receive medication information, such as infusion parameters, medication names, or order identifiers, after the information reader scans a medication barcode.

In practice, a nurse could use a barcode scanner to first scan the tag displayed on the infusion pump. This action associates the scanner with that particular pump. Subsequently, when the nurse scans the barcode on a medication bag, the information from that scan is automatically routed to the associated infusion pump, ensuring the correct medication and dosage parameters are used. This eliminates the need for manual data entry and reduces the risk of errors.

This approach differs from prior solutions by creating a dynamic and direct link between the scanner and the medical device. Instead of relying on a central system to interpret scans and relay information, the infusion pump itself becomes the endpoint . The use of a dynamically generated or static scannable tag on the device allows for easy association and disassociation, providing a more streamlined and error-free medication administration process. The system can also incorporate a device agent to manage scan workflows and rules, adding another layer of safety and control.

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2010s when ’180 was filed, at a time when barcode scanning was increasingly integrated into medical workflows, systems commonly relied on dedicated barcode scanners physically tethered to specific medical devices, and when communication capabilities between scanners and devices were often limited, making flexible and direct communication non-trivial.

Novelty and Inventive Step

The examiner approved the patent because the independent claims recite uniquely distinct features related to medical devices, specifically infusion pumps or systems, and the association of information readers with medical devices. The closest prior art fails to anticipate or render obvious certain limitations of the independent claims, particularly the ability of the infusion pump to render a scannable tag on its display, which can be read by an information reader to uniquely identify the infusion pump, and to receive medication information after the information reader scans a medication barcode.

Claims

This patent contains 30 claims, with independent claims 1 and 16 directed to an infusion pump and an infusion system, respectively, that render a scannable tag and receive medication information. The dependent claims generally elaborate on the features and functionalities of the infusion pump and system described in the independent claims.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Information reader
(Claim 1, Claim 16)
“Oftentimes, a barcode scanner is permanently associated with a single medical device. For example, the barcode scanner is physically attached to the medical device. As a result, the flexibility of a medical environment is limited because it is difficult to share barcode scanners with other medical devices.”A device capable of scanning the scannable tag on the display.
Medical device information
(Claim 1, Claim 16)
“For floating barcode devices, barcode scans are sent to a centralized system. The scanning is only done to get information (e.g., device id, similar to when you scan a badge), and the information is used in backend systems to perform some general work.”Data that uniquely identifies the infusion pump or system.
Medication barcode
(Claim 1)
“Barcode systems are often used in medical environments to ensure safety. For example, a barcode system can ensure that correct drugs are given to the proper patient or only authorized personnel can administer the proper medical protocol to a patient.”A barcode on the medication that can be scanned to obtain medication information.
Medication information
(Claim 1, Claim 16)
“Barcode systems are often used in medical environments to ensure safety. For example, a barcode system can ensure that correct drugs are given to the proper patient or only authorized personnel can administer the proper medical protocol to a patient.”Data related to the medication to be administered, including at least one of an infusion parameter, a medication name, or a medication order identifier.
Scannable tag
(Claim 1, Claim 16)
“Oftentimes, a barcode scanner is permanently associated with a single medical device. For example, the barcode scanner is physically attached to the medical device. As a result, the flexibility of a medical environment is limited because it is difficult to share barcode scanners with other medical devices.”A visual representation displayed on the infusion pump or system that can be read by an information reader. The tag provides medical device information that uniquely identifies the infusion pump or system.
