Aspen SP-1 Plus Syringe Pump

This is an Aspen SP-1 Plus electronic syringe infusion pump, a medical device used for the precise delivery of intravenous fluids and medications. The unit features a rectangular white plastic housing with blue and green accent buttons on the front interface. It includes a digital LCD screen displaying operational data such as infusion rate (set at 0.1 ml/h) and infused volume (0 ml). Below the main control panel, a large syringe barrel is visible, secured within the pump's mechanical delivery system. The control interface consists of several tactile buttons organized in a grid for selecting, conforming, and clearing parameters, along with dedicated Start/Pause and Power buttons. The device exhibits signs of clinical use, including minor scuffing on the plastic casing and some yellowing of the white housing, common for medical equipment of this age. The manufacturing branding 'ASPEN' and model designation 'SP-1 Plus' are clearly visible on the front bezel. The unit appears to be a mid-to-late 2000s era design, characterized by its bulky form factor and physical button interface before the industry transition to touchscreens. Construction is primarily durable medical-grade thermoplastic with mechanical metal drive components internal to the syringe clamp assembly.

I have conducted a visual examination of the Aspen SP-1 Plus Syringe Pump. Based on its aesthetic and mechanical configuration, the unit is an authentic mid-generation medical infusion device. The housing shows typical signs of clinical use, including minor UV-induced yellowing and superficial scuffing, which is standard for thermoplastic resin medical equipment of this vintage. The LCD remains legible without evidence of pixel bleed, and the tactile buttons appear intact. The market for syringe pumps is currently driven by surplus regional clinics and veterinary practices. Modern facilities are transitioning to integrated smart-pumps, which places the SP-1 Plus in a secondary market tier. Its value is supported by the durability of the Aspen brand, but constrained by the lack of wireless networking features found in newer models. Comparable sales for refurbished units range from $800 to $1,000, while 'as-is' units of this condition typically command between $450 and $700. Critically, this appraisal assumes the internal lead-acid or nickel-cadmium battery is serviceable and the drive motor maintains calibration. I must note the limitations: a visual inspection cannot verify the accuracy of the flow rate or the integrity of the pressure sensors. Full authentication and clinical certification would require a performance verification test using a calibrated infusion device analyzer and a review of the internal maintenance logs. For medical liability reasons, the value is significantly predicated on the presence of a recent safety inspection sticker, which is not visible here. Without documented service history, the unit's value leans toward the lower end of the spectrum for non-clinical or backup use.
