Sino MDT SN-50C6 Syringe Pump Analysis Report

Device Identification and Purpose of Use

The medical device shown in the image is an automatic syringe pump used for injecting fluids into patients at precise dosages and controlled speeds. The device is designed in a horizontal form, featuring control buttons and indicators on its front panel, and a syringe fixing mechanism at its lower part, making it a compact medical unit. The product is not an accessory but a standalone main unit.

Brand and Model Identity

Based on the information located in the upper right corner of the device’s front panel, the brand and model have been definitively identified:

• Brand: SINO MDT (Sino Medical-Device Technology Co., Ltd.)
• Model: SN-50C6
• Website Reference: The manufacturer’s website address “www.sinomdt.com” is indicated on the panel.

General Condition and Authenticity

Upon examining the print quality of the logos on the device, the panel layout, and the font characteristics of the “SYRINGE PUMP” inscription, the product is assessed to be an original SINO MDT production. The device is second-hand and has a used appearance. Although its overall integrity is preserved, there are traces consistent with its usage history.

Physical Condition and Deformation Analysis

The physical details identified during the visual inspection are as follows:

• Case Condition: No significant cracks, deep fissures, or heavy impact marks are visible on the device’s white/cream-colored outer plastic casing. However, slight yellowing and dullness on the plastic surface, developed over time, can be observed.
• Cleanliness: Dust accumulation and slight dirt stains are present at the device’s upper joints, grooves, and edges of mechanical parts. A general cleaning is understood to be necessary.
• Mechanical Components: The turquoise (light green/blue) colored syringe clamp lever and the piston pushing mechanism located at the bottom are visually in place. The plastic part on the clamp lever appears intact.

Technical and Electronic Component Analysis

Although the device appears to be in the off position in the image, the following technical inferences can be made from the control panel:

• Control Panel: It features a membrane keypad (soft touch). No erasure or significant wear is observed on the keys. The keypad consists of the following sections:
  • Power button on the left side.
  • Up/down adjustment arrows, “Pause”, and “Start” buttons in the middle section.
  • “Select”, “Silence” (Alarm Mute), “Delivery”, and “Purge” buttons on the right side.
• Screen: There is an LED segment display area on the panel showing numerical values. It is currently off or displaying a shadow image like “888.8”. Additionally, there is a single-digit digital area on the right for the “Occlusion Limit” indicator.
• Indicators: The panel features flow units such as ml/h, ∑ml, a battery level icon, and an electric plug icon. Furthermore, under the “Alarm” heading, there are warning LEDs for “Occlusion”, “Nearly Empty”, and “Finish”.
• Syringe Compatibility: The numbers “10, 20, 30, 50” are visible in the lower left part of the panel. This indicates that the device is compatible with standard syringes of 10ml, 20ml, 30ml, and 50ml sizes.

Operational Instructions and Warning Labels

On the right front face of the device, there are printed permanent operational instructions for the user. These points, written in English, are:

• 1. Press “Pause” before adjusting flow rate.
• 2. Do not move the syringe clamp during injection.
• 3. Use specified syringes, otherwise calibration is required.
• 4. Recharge timely when battery is low, otherwise permanent damage may be caused to the battery.

Accessories and Battery Status

• Accessories: No external cables (power cable), infusion sets, or syringes are attached to the device in the image. Only the device itself is shown.
• Battery Information: The battery indicator on the panel and the warning text in point 4 (“Recharge timely…”) confirm that the device has an internal rechargeable battery. The physical condition or capacity of the battery cannot be determined from the image.

Potential Risks and Conclusion

The device visually possesses a robust integrity. No obvious damage (e.g., broken screen, detached button) that would impede functionality is visible on its casing, screen, or buttons. However, considering the device’s dusty condition and the “battery warning” label, a detailed cleaning, sterilization, and a technical service check of the battery’s health are recommended before use. There is no visual evidence of a serious malfunction risk (e.g., burn marks, rust, exposed wires).
