Medtronic MiniMed Paradigm REAL-Time Revel (MMT-523NAS) Insulin Pump Analysis Report

Device Identification

The examined visuals pertain to an insulin pump and its box contents, which is a medical electronic device designed for diabetes treatment and management. The product consists of a set presented in its original packaging and protective enclosures.

Brand and Model

Brand and model information has been definitively determined as a result of detailed examinations of the product box, the front of the device, and technical labels:

• Brand: MEDTRONIC (MiniMed series)
• Model: Paradigm REAL-Time Revel
• Reference Model Code: MMT-523NAS

This information is 100% consistent with the prints on the front of the box and the data on the technical label on the side.

Originality

Considering the print quality of the product box, the embossed “Medtronic MINIMED” logos on the plastic enclosure where the device and accessories are placed, the craftsmanship quality of the device, and the compliance of the technical label with standards, the product appears to be an original Medtronic production. Packaging details reflect factory-standard specifications.

Areas of Use

This device is used to continuously and programmatically deliver insulin to the bodies of diabetic patients (such as those with Type 1 diabetes). The device allows the user to manage basal and bolus insulin doses. The MMT-523NAS model shown in the visual has integrated features that can also help monitor blood glucose levels when used with appropriate sensors. The “Rx Only” statement indicates that the product is a prescription medical device and should be used under professional medical guidance.

Quantity Information

According to the visual inspection, the box contents are as follows:

• 1 Insulin Pump Device
• 2 accessories in sealed nylon bags (Likely a belt clip and battery cap/activity protector or similar spare part)
• 1 “Daily Journal” (Logbook/Booklet)
• 1 Bayer brand “Clinilog – Blood Sugar Logbook”

General Condition

According to visual inspection, the device is in “unused” or “new (in box)” condition. The insulin pump rests in its specially molded plastic tray slot. The accessories next to it are in factory-sealed nylon packages and have not been opened. However, the date information on the label indicates that the product’s manufacturing dates back to earlier years, suggesting it can be considered “New Old Stock”.

Physical Deformation

No scratches, dents, cracks, discoloration, or dirt have been detected on the device’s casing, screen, buttons, or plastic tray in the visuals. The cosmetic condition of the device is excellent.

Mechanical Components

The buttons (“B”, “ACT”, Direction keys) on the device and the external plastic casing appear sound. The carrier plastic tray inside the box retains its shape, with no breakage observed.

Electronic Components

The body of the device, which houses its electronic components, appears sturdy from the outside. The device is in an off state in the visuals, so there is no visual data regarding the screen’s pixel status or electronic functionality. No cracks are visible on the screen glass.

Accessories

Accessories are present in transparent bags alongside the device inside the box. As the packages of these accessories are unopened, the exact contents are not clearly visible, but based on their form, one is understood to be a transparent belt clip or carrying attachment. No visual deficiencies or damage are apparent on the accessories.

Battery Status

It is not externally discernible whether a battery is installed inside the device. These devices typically operate with replaceable batteries (e.g., AAA battery). No loose or leaked battery is visible inside the box, which suggests that the device has been stored without a battery, thereby minimizing the risk of battery leakage.

Label Information

Critical information on the label on the side of the box is as follows:

• REF (Reference Number): MMT-523NAS
• SN (Serial Number): PAR875545H
• CONF Code: H026
• Manufacturing Date: 2010-12 (December 2010)
• Lot / Batch Code: A3523NASJ
• Part Code: MMT-523NAS
• UCC Barcode Information: (01)00613994743886 (21)PAR875545H
• Storage Conditions: -20 °C to +55 °C
• Color Code: X-marked box (Matches Black/Charcoal color)

Year of Manufacture

Based on the label information on the box, the device’s manufacturing date has been determined to be December 2010 (2010-12).

Documents

Two written documents are visible inside the box: Medtronic “Daily Journal” and Bayer “Clinilog Blood Sugar Logbook”. It cannot be determined from the visuals whether a warranty certificate or invoice is present, but due to the age of the product (manufactured in 2010), the manufacturer’s warranty is likely to have expired.

Existing Faults and Potential Risk Assessment

Visually, there are no signs of breakage, detachment, or physical malfunction on the device. The device appears unused.

However, the fact that the device was manufactured in 2010 (approximately a 14-15-year-old device) requires attention to certain potential issues. Even if the device has never been used, internal electronic components, seals, or (if present) internal memory batteries may have reached the end of their shelf life over time. In medical devices, rubber seals losing their elasticity over time can affect the sealing risk. The physical condition of the device is flawless; however, it is recommended to have it checked by a technical service before use.
