Intended Use

The Sensititre® AIM™ is intended for use with the Sensititre® MIC or BP Susceptibility Test System. The Sensititre® AIM™ is an instrument used to inoculate Sensititre® MIC or BP Susceptibility plates. The Sensititre MIC or Breakpoint Susceptibility System is an in vitro diagnostic product for clinical susceptibility testing of gram positive and fastidious organisms comprising of Haemophilus influenzae, Streptococci pneumoniae, other Streptococci spp. and Candida spp.

Device Story

Sensititre AIM™ is a microprocessor-controlled, bench-top automated pipette system for inoculating 96-well micro-titre plates used in antimicrobial susceptibility testing (AST). User prepares bacterial suspension; affixes disposable dosehead to glass tube; places tube into pump assembly. User selects well dose volume (50μl multiples) via graphical display. Instrument dispenses inoculum into plates. Stand-alone device; no sample tracking or external connectivity. Healthcare providers use output (MIC plates) to determine bacterial susceptibility to antimicrobial agents, aiding clinical treatment decisions. Benefits include standardized, automated inoculation compared to manual methods.

Clinical Evidence

No clinical data provided; device is an automated laboratory instrument for plate inoculation.

Technological Characteristics

Microprocessor-controlled pump assembly; dispenses 50µl multiples; utilizes disposable doseheads; designed for 96-well microtiter plates; standalone laboratory instrument.

Indications for Use

Indicated for clinical susceptibility testing of gram-positive and fastidious organisms (Haemophilus influenzae, Streptococci pneumoniae, other Streptococci spp., and Candida spp.) using the Sensititre MIC or BP Susceptibility Test System.

Regulatory Classification

Identification

An antimicrobial susceptibility test powder is a device that consists of an antimicrobial drug powder packaged in vials in specified amounts and intended for use in clinical laboratories for determining in vitro susceptibility of bacterial pathogens to these therapeutic agents. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.
