Mindray PM-9000 Express Patient Monitor Analysis Report

Device Identification and Product Description

The device shown in the visuals is a portable patient monitor designed for medical use, serving to monitor vital functions. The device is displayed as an integrated unit with its built-in screen, user interface control buttons, sensor connection ports on its side panel, and a carrying handle. It is an electronic medical device manufactured for healthcare professionals to monitor patient data.

Brand and Model Information

The findings based on the clear inscriptions located on the front face of the device, in the upper left and upper right corners, are as follows:

• Brand: Mindray
• Model: PM-9000 Express
• Product Type: Patient Monitor

The brand and model information is indelible and clearly readable on the device’s front bezel.

Areas of Use and Compatibility

This monitor is used in hospital intensive care units (ICUs), emergency departments, operating rooms, and patient wards to continuously monitor the patient’s vital signs. According to the connection points on the side panel, the device has the capability to measure and monitor the following parameters:

• EKG (ECG): Heart rhythm monitoring.
• SpO2: Blood oxygen saturation.
• NIBP: Non-invasive (cuff) blood pressure measurement.
• IBP (1 and 2): Invasive blood pressure monitoring (two channels).
• T1 and T2: Body temperature measurement (dual channel).
• CO2: Carbon dioxide analysis (Capnography).
• CO: Cardiac Output measurement.

Quantity Information

The visuals show a single main unit (1 monitor). Beyond the monitor, sensor cables, external accessories, or consumable materials are not visible as a set (only a single white cable/connector end partially attached to the side panel is visible in the 2nd visual).

Originality and Label Information

The logos, fonts, button icons, and port labels on the device (expressions such as “CO2”, “NIBP”, “MINDRAY PATIENT MONITOR”) are in exact compliance with original Mindray manufacturing standards. The symbols on the side connection panel (heart and arrow signs) reflect professional medical device standards. No visual evidence suggesting it is a copy or imitation has been found.

The following technical labels indicating the functions of the ports are located on the side panel:

• CO2
• T1, T2 (Temperature)
• IBP1, IBP2 (Invasive Pressure)
• ECG (Electrocardiography)
• CO (Cardiac Output)
• NIBP (Blood Pressure – Pneumatic input)
• SpO2 (Oxygen Saturation)

General Condition and Physical State

Upon visual inspection, the device appears to be in second-hand (used) condition. Detailed notes regarding its physical condition are as follows:

• Casing: The device’s white plastic front bezel, particularly along the upper edge (around the “PM-9000” inscription) and near the brand logo, shows accumulated dirt marks, scuff marks, and discoloration. Adhesive-like stains are noticeable in the area where “PM-9000” is written.
• Screen: The screen is in the off position. While no severe cracks are visible on the surface, environmental reflections are present due to the screen’s brightness; therefore, micro-scratches cannot be clearly distinguished. However, the screen appears to be intact.
• Cleanliness: Dust/dirt accumulation is observed particularly inside and around the edges of the ports on the side panel (especially the IBP and CO sockets). The device requires general cleaning maintenance.

Mechanical and Electronic Component Analysis

The hardware inspection based on the visuals is as follows:

• Control Buttons: The soft keys located at the bottom of the front panel (Main, Freeze, Silence, Record, Start, Menu) and the Blue rotary menu knob are in place. No missing, broken, or dislodged buttons are observed.
• Power Button: The blue power button in the lower left corner appears intact.
• Ports and Sockets: The sensor input ports (sockets) on the side panel appear mechanically sound. No obvious crushing or breakage of pins is visible from a distance, but as mentioned above, the port housings are dusty. The blue cap/bezel of the SpO2 port is present. The NIBP metal air inlet is in place.
• Ventilation: The grilles on the side rear of the device are open; no physical obstruction is visible.

Accessories

The visuals do not include medical sensors and cables necessary for the device’s operation, such as ECG cable, SpO2 probe, blood pressure cuff, or temperature probe. Only the main unit has been reported. The power cable is also not clearly presented in the visuals (the nature of the white connector seen at the rear in the 2nd visual is unclear, but it likely belongs to an accessory attached to the device).

Battery Status

On the front panel, next to the power button, there is a “CHARGE” inscription and an LED indicator. This indicates that the device has an internal battery. However, a technical inference regarding the battery’s lifespan, whether it holds a charge, or if it is swollen, cannot be made based on the visuals.

Existing Malfunctions and Potential Risks

There is no active evidence in the visuals that the device is showing an “Error” or that its screen is faulty because the device is off. However, the following conditions may pose potential risks:

The dirt on the device’s outer casing, and especially in the port inlets, suggests that the device has been stored in a non-sterile or dusty environment. Dust accumulation inside the ports could lead to connection issues (poor contact) when sensor cables are attached. Apart from this, no visible cracks or fractures that could impede its operation, beyond the cosmetic condition of the casing, have been detected.
