When considering the principles of a pain control strategy by patients, reliable administration of additional bolus doses is important for providing the adequate analgesia and improving patient satisfaction. We compared the efficacy of elastomeric patient-control module (PCM) with conventional PCM providing epidural analgesia postoperatively.A noninferiority comparison was used. Eighty-six pati...

This paper describes optical components prepared using poly(dimethylsiloxane) elastomers and liquid metals as constituent materials. Most optical components are fabricated from rigid materials such as glass, rigid polymers, or metals. By contrast, the elastomeric optics described here are designed to be deformable. Because the structure of the optical surface can be deformed easily, a single el...

www.ejhp.org 54 INTRODUCTION Elastomeric devices are disposable infusion pumps mainly consisting of an elastomeric reservoir in which the solution to be administered is placed, and a flow restrictor system located in the administration tube set. The combination of both the pressure generated by the filled reservoir and the flow restrictor, sets a fixed flow rate of the solution according to Poi...

BACKGROUND One of the frequent applications of elastomeric infusion pumps is postoperative pain management. In daily practice, the disposable pumps get refilled with modified medication combinations in the successive days; although, the accuracy of infusion rates is unknown to clinicians. OBJECTIVES Our aim was to evaluate the effect of repeated filling on the delivery rate accuracy of an ela...

INTRODUCTION The maxillomandibular relationship (MMR) record is a critical step to establish the new occlusion in implant supported complete mouth rehabilitation. Using patients existing denture for recording the MMR requires implant definitive cast to be modified extensively to completely seat the denture (with unaltered flanges) on it. This may influence the correct seating of the denture on ...

This paper demonstrates a method for tuning elastomeric microchannels for hydrophoretic separation made in poly(dimethylsiloxane) (PDMS). Uniform compressive strain is imposed on the elastomeric microchannel between two acrylic substrates by fastening the bolts. The elastomeric microchannel can change its cross-section during compression, simultaneously tuning the criterion for hydrophoretic or...

OBJECTIVE To investigate the effects of different sterilization/disinfection methods on the mechanical properties of orthodontic elastomeric chains. METHODS Segments of elastomeric chains with 5 links each were sent for sterilization by cobalt 60 (Co60) (20 KGy) gamma ray technology. After the procedure, the elastomeric chains were contaminated with clinical samples of Streptococcus mutans. S...

INTRODUCTION Sterilisation using peracetic acid (PAA) has been advocated for orthodontic elastic bands. However, cane-loaded elastomeric ligatures can also become contaminated during processing, packaging, and manipulation before placement in the oral cavity and are therefore susceptible, and possible causes, of cross-contamination. AIM To test the hypothesis that 0.25% peracetic acid (PAA), ...

Elastomeric petals directly replicated from natural rose petal are new versatile substrates for stretchable and printable electronics. Compared with conventional flat polydimethylsiloxane substrates, elastomeric petals have biomimicking topographic surfaces that can effectively inhibit the propagation of microcracks formed in the conducting layer, which is deposited on top, regardless of the ty...

been used to direct the eruption of an impacted tooth by applying force to an attachment on the tooth. One such attachment is the versatile “loop-button” or bondable eyelet, a 1mm helix of round wire welded or brazed to a small bondable base. The Monkey Hook* is a simple auxiliary with an open loop on each end for the attachment of intraoral elastics or elastomeric chain, or for connecting to a...
