Gemstar Blue

The Hospira Gemstar is a single channel infuser designed for use in home care and hospital settings.


The GemStar Pump is a small and lightweight, single­-channel infusion device designed for use in the home, in the hospital, or anywhere electronic infusion is required. The GemStar Pump can be powered by AC mains adaptor, rechargeable battery pack, docking station, or two disposable AA alkaline or lithium batteries. When powered by batteries, the GemStar Pump is ideal for ambulatory patients.

Current program and 400­event history log protected by internal lithium battery­-backed memory for at least one year after power is removed 

Operating Controls: 

One 23­-key keypad. Bolus, data port, and AC mains jacks. Bolus button.

External Power Led: 

Green LED marked with plug icon illuminates continuously when the infuser is connected to AC mains. Green LED blinks when the infuser is connected to external batteries

Alarm Led:

Red LED marked with alarm icon illuminates continuously for self-­test error alarm conditions Red LED blinks during all alarm conditions which are user-recoverable

Audible Alarm: 

The audible alarm is user­adjustable from the maximum volume down to silent. The alarm automatically reverts to the maximum volume if the user does not respond within one minute 


Backlit, four-­line-­by-­sixteen-­character alphanumeric graphics display

Distal Occlusion


Low: Alarms when infuser detects distal pressure greater than 7 psi (48 kPa) ± 5 psi (± 34 kPa)
Medium: Alarms when infuser detects distal pressure greater than 12 psi (83 kPa) ± 8 psi (± 55 kPa)
High: Alarms when infuser detects distal pressure greater than 26 psi (179 kPa) + 14 psi (+ 96 kPa)

Proximal Occlusion: Alarms when infuser detects proximal pressure less than or equal to ­-4 psi ( -28 kPa)

Piggyback Rate: 0.1 ­ 300 mL per hour
Infuser Self Tests snd Safety Features: 
Self test performed when the power switch is activated. Diagnostic routine, including motor speed and air-­detection monitoring, is repeated continuously while the infuser is powered on. Error and alarm conditions are indicated by both audible and visual alarms; delivery in progress is stopped, if appropriate.
