Refining bioreactor design using autoclavable glass bonding

Ceramics Bonding Using Solder Glass Frit

Ceramics bonding is becoming an important technology and has found wide applications in different engineering and electronic industries. In this paper, furnace bonding of ceramics using solder glass frit was investigated with emphasis on the effects of surface treatment and bonding conditions on bonding strength. Alumina (Al2O3) sheet and SCHOTT solder glass G017-393 were used as the base and b...

Design of an Autoclavable Active Cannula Deployment Device

Concentric tube continuum devices, known as active cannulas, consist of multiple pre-curved elastic tubes that extend telescopically and rotate axially with respect to each other. Through these degrees of freedom, an active cannula presents a dexterous and versatile “tentacle-like” mechanism for accessing targets in minimally invasive surgery. Deploying an active cannula in a practical surgical...

A Hermetic Glass–Silicon Package Formed Using Localized Aluminum/Silicon–Glass Bonding

A hermetic package based on localized aluminum/silicon-to-glass bonding has been successfully demonstrated. Less than 0.2 MPa contact pressure with 46 mA current input for two parallel 3.5m-wide polysilicon on-chip microheaters can raise the temperature of the bonding region to 700 C bonding temperature and achieve a strong and reliable bond in 7.5 min. The formation of aluminum oxide with sili...

An autoclavable ventilation failure alarm.

A small ventilation failure alarm which can be used with all types of lung ventilator is described. The entire patient circuit can be removed and autoclaved easily. Activation of the unit is by a removable key, a mains failure warning is provided, and alarm may be muted during aspiration of secretions from the tracheobronchial tree.
