Imed Infusion Devices

Imed infusion pumps are general-purpose home and hospital devices that are inexpensive and simple to operate. Can be used for most critical medication infusions, including parenteral and enteral. Because of piston/displacement operation, ideal for blood infusions with specialized sets. Can be adapted for use of direct infusion via syringe, a useful feature for Nuclear Medicine or Radiology stress testing injections. Although the pumps themselves tend to rent and sell at lower prices, the dedicated cassette-style sets can be expensive. All models share the same type of sets except for the 965 micropump, which has its own unique dedicated set list.

Imed and IVAC recently merged to form a new corporation, Alaris Medical, which subsequently announced its intention to discontinue manufacture of all Imed models except the Gemini PC series.

 

Imed 928

Imed 922, 927, 928

Popular with hospital clinicians for many years because of simplicity and durability (rigid metal case housings), these pumps incorporate thumbwheel rate and volume data entry, and alarms for air-in-line, occlusion, and low battery. High accuracy, 2%. Integral side-mounted pole clamp. The 922 is similar to the 927 and 928 in operation and appearance, but has air-in-line detection for clear fluids only, vs. air detection of clear and opaque fluids in later models. The 928 improves on the model 927 only in the expanded range of rate parameters.

All of these models are now discontinued, but parts are still available because of the continued popularity of these pumps.

Rate parameters: 922 & 927: 1-299 ml/hr in 1 ml increments
928: 1-799 ml/hr in 1 ml increments
Volume parameters: 1-9999 ml in 1 ml increments
Occlusion pressure: 10 - 25 PSI
Battery capacity: 8 hours at 125 ml/hr.
Accuracy: 2%

Imed 960, 960A, 965 Micro

Imed 960A and Imed 960

Imed 965 Micro

Rigid plastic case reinforced by metal plate, with thumbwheel rate and volume entry. 960 and 965 have top LCD display for infusion information, which was moved to the front panel in the more recent 960A’s to make viewing easier. 960A’s also added an automatic prime feature, and replaced the thumbwheels with digital input and an LED data screen. All have an enclosed operating area with clear plastic door to limit fluid spills. A recent internal upgrade reduces nuisance alarms by 2000% for TPN infusions, but is not installed on every pump in inventory. The 965, a micro-rate pump used for neonatal and pediatric infusion, requires a different dedicated set than all other Imed models. Also made, but generally unavailable: 965A.

Rate Parameters: 960, 960A: 1 - 999 ml/hr in 1 ml increments
965, 965A: 0.1 - 99.9 ml/hr in 0.1 ml increments
Volume parameters: 960, 960A: 1 - 9999 ml in 1 ml increments
965, 965A: 0.1 - 999.9 ml in 1 ml increments
Occlusion pressure: 960, 965: 10 - 25 PSI 960A, 965A: approx. 18 PSI
Accuracy: 5%

Imed 970, 980

Imed 970 and Imed 980

These Imed models are distinguished by their higher-than-usual rate range, which makes them useful for therapies which require high flow rates, such as some cancer treatments or high-volume hydration therapy for burn victims. They feature push-button programming with LED readouts, automatic priming, fluid-sealed plastic panel and case.
Rate parameters: 970: 1 - 1200 ml/hr in 1 ml increments
980: 1 - 2000 ml/hr in 1 ml increments
Volume parameters: 1 - 9999 ml in 1 ml increments
Occlusion pressure: Variable- Low: 8 ( 3) PSI High: 18 ( 3) PSI
Battery capacity: 8 hours at 125 ml/hr.
Battery recharge: 12-18 hours
Accuracy: 5%

Imed Gemini PC-1 and PC-2

Imed Gemini PC-1

Imed Gemini PC-2

The Imed Gemini PC-1 is a single-channel, linear peristaltic volumetric infusion device with ultrasonic air detection, which can be operated either as a controller or as a positive-pressure pump. Secondary (piggyback) medications can be automatically infused at rates and volumes independent of the primary infusion parameters, with automatic changeover to the primary at the conclusion of the secondary infusion. The PC-1 also has a 20-step program feature, called the VersaTaper mode, which allows stepped program of sequential rates and volumes for TPN or antibiotic infusion. The pump can be configured as a Micro pump (rates from 0.1-99.9 ml/hr.) or as a Macro pump (1-999 ml/hr). An RS-232 port is included and allows the pump to serve either as the control or slave unit for computer monitoring.

The Imed Gemini PC-2 is a dual-channel version of the PC-1 and incorporates most of the features of the single-channel version. It does not include the VersaTaper stepped program mode. Each channel can be independently-programmed.

Newer versions of both pumps allow titration of rates while the pump is operating. The Geminis use a variety of dedicated Gemini infusion sets, each of which incorporates a clamping device which prevents inadvertent free-flow.

Rate parameters: MICRO mode 0.1-99.9 ml/hr in 0.1 ml increments
MACRO mode 1-999 ml/hr in 1 ml increments
(recommended maximum in controller mode is 500 ml/hr)
Volume limits: MICRO mode 0.1-999.9 ml. in 0.1 ml increments
MACRO mode 1-9999 ml. in 1 ml increments
Battery Life: approx. 5 hours with one channel operating at 125 ml/hr before "Help/Battery" alarm, or 4 hours with 2 channels operating at 125 ml/hr.
KVO rate: 1 ml/hour, or infusion rate if less than 1 ml/hr.
Occlusion Pressure: 10 2 PSI for rates above 30 ml/hr.
< 10 PSI and rate-dependent for rates under 30 ml/hr., unless 10 PSI is locked-in for all rates.
Accuracy: 5 %
