PURPOSE The properties, performance, and applications of nonelectric disposable infusion pumps are reviewed. SUMMARY All nonelectric disposable infusion pumps exploit the same physical principle: mechanical restriction within the flow path determines the speed of pressurized fluid. The pressure generated by disposable pumps on fluid is 250-600 mm Hg, compared with 5-1200 mm Hg of pressure for...

Since there is no detailed hospital based incident reporting system, this study was designed to evaluate the medication errors associated with infusion pumps in intensive care unit (ICU). The investigation was conducted in a Teaching hospital in the form of a prospective, observational study. A sample size of 43 doses administered to ICU patients was chosen to enable reliable estimate of error ...

A new model of pump noise in supercontinuum and rogue wave generation is presented. Simulations are compared with experiments and show that the new model provides significantly better agreement than the currently ubiquitously used one-photon-per-mode model. The new model also allows for a study of the influence of the pump spectral line width on the spectral broadening mechanisms. Specifically,...

An unprecedented combination of high propellant fraction and small size is required for affordable-scale Mars return, regardless of the number of stages, or whether Mars orbit rendezvous or in-situ propellant options are used. Conventional space propulsion technology is too heavy, even without structure or other stage subsystems. The application of launch vehicle design principles to the develo...

AIM To evaluate the use of intraosseous lines for rapid vascular access in primary resuscitation of preterm and full term neonates. METHODS Thirty intraosseous lines were placed in 27 newborns, in whom conventional venous access had failed. RESULTS All the neonates survived the resuscitation procedure, with no long term side effects. CONCLUSION Intraosseous infusion is quick, safe, and ef...

This paper introduces an extended hierarchical task analysis (HTA) methodology devised to evaluate and compare user interfaces on volumetric infusion pumps. The pumps were studied along the dimensions of overall usability and propensity for generating human error. With HTA as our framework, we analyzed six pumps on a variety of common tasks using Norman's Action theory. The introduced method of...

BrdU infusion into normal cats: Osmotic pumps (ALZET) were filled with 50mg/mL BrdU dissolved in 50% DMSO/50% ddH2O filtered through a sterile 0.22μm filter. Pumps were then incubated in sterile saline at 37 °C overnight prior to insertion. The pumps were surgically inserted subcutaneously just caudal to the scapulae per the protocol approved by IACUC at Temple University. The number of pumps w...

BACKGROUND The use of insulin pumps is rapidly increasing and new, technologically more advanced pumps are continuously being developed. It is of interest to assess the clinical relevance of the many technical features of these pumps, e.g., the effect on pharmacokinetics and pharmacodynamics with change in infusion rate. METHOD The aim of this study was to explore the sequence of pharmacokine...
