Welch Allyn MicroPaq Patient Monitor and Charger Analysis Report

Product Overview

The images show patient monitoring devices for medical use and their corresponding accessories. Upon inspection, the products were identified as Welch Allyn brand MicroPaq model patient monitors and charging stations designed to charge the batteries of these monitors. The “ECG” and “SpO2” inputs on the monitors indicate that these devices are used for real-time monitoring of patients’ electrocardiography (heart activity) and oxygen saturation levels. The overall structure, labels, and workmanship of the products give the impression that they are genuine.

Package Contents and Quantity

A breakdown of the products shown in the images is listed below. It has been observed that some essential components required for the products’ operation are missing.

• Patient Monitor: 7 Units, Welch Allyn MicroPaq
• Battery Charger: 2 Units (Each has the capacity to charge 8 monitor batteries)
• ECG Cable: 3 Units, Welch Allyn

Important Note: The images do not show the batteries for the monitors, the power cords for the chargers, or the finger sensors required for SpO2 measurement.

General State and Condition

All devices and accessories are lightly used and in very good physical condition. The surfaces of the products are clean and have a generally well-maintained appearance. No significant wear, discoloration, or dirt accumulation was observed on any device or accessory. This suggests that the products have been meticulously stored.

Physical and Mechanical Evaluation

Casing and Surface: There are no cracks, breaks, or deep scratches on the plastic casings of the monitors and charging stations. Only very slight superficial marks, likely from normal use, are present.

Screens: The screens of all 7 monitors are intact. No cracks, stains, or scratches that would affect image quality were detected on the glass surfaces.

Ports and Connectors: The SpO2 and ECG socket inputs on the monitors and the power input on the back of the chargers are clean and undamaged. The connectors on the ECG cables are also in good condition.

Mechanical Parts: The covers and locking mechanisms of the 16 battery slots on the charging stations appear to be functioning properly. The control buttons on the monitors are also physically complete and show no signs of damage.

Labels and Technical Information

The labels on the devices and accessories contain important technical details and codes. This information is as follows:

• Patient Monitor Label:
  • Brand: Welch Allyn Protocol Inc.
  • Model: 90102
  • Power Requirement: 8.4V — 160mA MAX
  • Warning: Contains the phrase “USE ONLY APPROVED BATTERY”.
• ECG Cable Label:
  • Brand: WELCH ALLYN, INC.
  • Reference Code (REF): 401660-01
  • Lot Numbers (LOT): Codes such as 180519A, 180519, and 180706 are present. These codes suggest that the cables may have been manufactured in 2018.
• Charger Label:
  • Model Name: MicroPaq Battery Charger
  • Brand: Welch Allyn

Missing Items and Potential Risks

There is no evidence in the images to suggest that the devices are faulty (e.g., breakages, error messages). The physical condition of the products is very high. However, the absence of batteries for the monitors and power cords for the chargers prevents the devices from being tested in their current state. These missing parts must be procured to make the devices operational. Based on the visual inspection, as no significant wear or damage has been observed, the products are assessed as having a high potential to function properly once equipped with the appropriate parts.
