Changing The Face Of Blood-Pressure Monitoring

Other specifications include an operating temperature range of 15°C to 40°C and ac power input requirements of 120 V, 60 Hz, at 0.5 A maximum. (A B version is rated at 100 to 240 V ac, 50 to 60 Hz, at 0.8 A maximum.) The TL-150 measures 10 in. wide by 8.5 in. high by 9 in. deep (including a pole clamp) and weighs 5 lb.

PROTOTYPING DESIGN CHALLENGES
Earlier prototypes of the TL-150, which were developed using SLA castings, didn't permit verification testing. Also, the production-tool vendor could not construct the product properly. (SLA is a universal file format used in a rapid prototyping process. This file type contains raw geometric data).

Facing looming time-to-market deadlines, Tensys engineers took an unconventional step backward and explored rapid injection molding for prototyping and pilot production. Working with Protomold Co., the rapid injection molding process delivered the parts in a time frame that was 90% faster than that from other molding companies (Fig. 3).
