CADD® Legacy PCA

1. Overview
The CADD‑Legacy ambulatory pump is a compact, reliable infusion device designed for continuous or demand-dose medication delivery. It supports both continuous infusions and patient- or clinician‑controlled bolus dosing, making it suitable for a wide range of therapies in hospital or home-care settings. The pump’s portability and flexibility make it especially useful for ambulatory patients who require ongoing infusion therapy.

2. Delivery Modes & Therapy Flexibility
-Continuous infusion: delivers a steady, programmed flow over time.
-Demand‑dose (Patient‑Controlled Analgesia / PCA or clinician‑administered): allows patient or clinician to trigger additional doses as needed.
-Combined modes: continuous infusion with supplemental demand doses (bolus) if therapy requires.
-Suitable for multiple delivery routes: intravenous, subcutaneous, epidural/intrathecal, or other medically approved routes (depending on therapy).
-Supports a variety of therapies: pain management, analgesia, possibly long‑term infusion needs (depending on medication and protocol).

3. Safety & Delivery Protection Features
-Cassette detection: verifies that the medication cassette is properly attached before infusion begins.
-Upstream and downstream occlusion detection: sensors monitor for blockages before and after the pump to immediately alert and stop infusion if flow is interrupted.
-Air‑in‑line detection: detects air bubbles in the infusion line (with sensitivity settings), triggering alarm and stopping infusion to prevent air embolism risk.
-Lock-out or secure access: pump can be configured to restrict unauthorized changes (for safety in patient-controlled use).
-Low‑power standby option: an ON/OFF control to place the pump into a low‑power state (e.g. during transport), conserving battery life.
-Event memory / log: records infusion history (events, alarms, doses) to support monitoring, troubleshooting or audits.

4. Programming & Usability Features
-Easy-to-read display: clear screen for programming, dose settings, alarms, and status info.
-Flexible programming: supports dosing in milliliters (mL), milligrams (mg) or micrograms (mcg) depending on medication concentration and therapy.
-Adjustable dosing parameters: allows setting of infusion rate, bolus doses, lock‑out intervals (for PCA), and reservoir volume as per therapy needs.
-User-friendly interface: menu-driven or keypad-based programming designed for ease of use, reducing risk of errors.
-Portability: small, lightweight, battery-powered — suitable for ambulatory patients, home care, or transport between care settings.

5. Technical & Physical Specifications
-Stroke volume (nominal): approx. 0.050 mL per pump stroke.
-Flow (continuous) range: from very low infusion rates up to ~125 mL/hr (depending on pump model and configuration).
-Reservoir / Cassette volumes: supports standard disposable medication cassettes of various sizes (e.g. 50 mL, 100 mL — depending on model), enabling flexibility in therapy duration.
-Power source: operates on 2 × AA alkaline batteries — optionally supported by AC adapter, allowing flexibility for ambulatory or clinical use.
-Size / Weight: compact dimensions and light weight (with batteries + empty cassette) — designed for portability and ambulatory use.
-Alarm and alert system: configured to warn for occlusion, air‑in‑line, cassette issues, low battery, infusion completion or other fault conditions.
-Compatibility: can be used with standard administration sets or compatible cassettes/reservoirs; adaptable for different medications and administration routes as approved.

6. Typical Clinical Applications
-The CADD‑Legacy pump can be used for:
-Pain management (e.g. PCA for post‑operative analgesia, chronic pain, or palliative care)
-Continuous infusion therapies (e.g. IV fluids, antibiotics, medications requiring steady rate)
-Ambulatory or home‑based infusion therapy (where portability, battery operation, and patient mobility are required)
-Situations needing flexible dosing — combined continuous + demand dosing, or patient‑controlled doses, especially for analgesia or other intermittent therapies
