Title: Electrochemical biosensor
Inventor: CHARLTON STEVEN C
IPC: G01N27/327
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To perform preparation through a simple procedure by making a recessed region in a cover through coining and forming a capillary space by heat sealing the cover to a base. SOLUTION: A recessed space 48 is made in a cover 46 by coining a flat seal member of a deformable material. A vent 50 is bored through the cover 46 which is then bonded to a base 36 by heat sealing. Acoustic welding may be employed for sealing. At first, the base 36 and the cover 46 are clamped, while being superposed, between a vibratory heat seal member or a horn and a fixed jaw and press fitted. A vibration is then excited in a metal horn with ultrasonic energy supplied from a crystal converter or other converter. Mechanical energy is dispersed as heat in plastic bonding to enable bonding of a thermoplastic material. Consequently, an integrated sensor having a capillary space for receiving a fluid sample is obtained wherein the use of extra component, i.e., a spacer, and a large number of machining steps are avoided using a coined cover 46.
