LENSAR Laser System

Bleck Design Group, LensAR Laser System

Bleck Design Group designed the external enclosure for this new ophthalmic laser. This medical device automates the removal of a patients natural lens prior to implanting an artificial lens (capsulotomy). This allows a reduction in surgical time and cost.

Concept Rendering for Investors: The project started with developing a concept rendering for investors. The goal of this phase was to illustrate the basic system and show investors and users the overall concept

User Survey and Ergonomic Design: Next we surveyed the ophthalmologists and developed the ergonomic concept for controls and patient interface. We completed anthropometric analysis to set ideal ranges of motion and resolved conflicts between the ideal range of motion and the prototype laser optics and electronics. We completed user reviews by taking a mock-up to several ophthalmologists offices and confirming the design would meet constraints. 

 

Industrial Design: Bleck Design Group then developed a range of industrial design concepts and selected a design direction. We refined this design in scale models and computer renderings of the external form then completed a preliminary engineering layout 

 

Transforming the Concept to Production: We then had four months to complete the production design of all the parts, fabricate a model and have the assembled final prototype at an annual trade show. In eight weeks our design and engineering teams designed over thirty five complex assemblies, coordinated fabrication across the country, and merged all the parts together, on schedule for the final product assembly.

 

Production Design: We then transformed each prototype part into a production ready design and released to production tooling. We managed the vendors and continued to fabricate prototype parts. Finally we transferred our documented design to the client's manufacturing group.

Senticare Pill Station®: Home Care Pill Dispenser

Home medical product design - SentiCare PillStation, a monitored pill dispenser

The Pill Station® by Senticare is a home based monitored pill dispenser. This Pill Station® helps a patient comply with drug regiments and avoid expensive hospitalization due to over and under dosage. Senticare conceived of a call-center based communication link in order to monitor home-care patients with critical medications. The PillStation® has a scanning camera that takes a picture of the pill tray contents and sends this to the call center. The call center then compares this picture to the patients drug plan. A speaker and microphone provide a one touch link to the call center. A display and signal light provides additional communication.

Start-Up Program

Bleck Design Group provided Senticare a complete Start-up set of design services. This represents our classic set of services that help new companies launch ground-breaking innovative products.

Founders and Investors

We helped the founders explain the design to investors and estimate the development costs. The concept was illustrated in models and drawings to provide an easy to understand product explanation.

Definition and Specification: Users were researched through interviews and presenting alternative concepts. Technology and components were selected, evaluated and transformed into feasibility models. User needs and technology were considered to make trade-offs and optimize performance and cost.

Concept to Production: Bleck Design Group provided industrial design, mechanical engineering, prototypes, and production sourcing. We provided a virtual design and engineering department for Senticare and worked as a part of their team as the design entered manufacturing.

Pill Tray - User Centered Design

The PillStation® has a novel (patent pending) pill tray designed to meet a wide range of behaviors in active patients. 

Bleck Design Group designed PillStation for easy use by elderly patients.    

Filling the Bin: Research showed patients and caregivers often organize medication once per week by sitting at a table and carefully loading each dose. Sitting at the PillStation would be impractical. So the entire weeks pills are snapped into a removable frame. This allows a caregiver to sit down at a table and carefully organize the doses.

Patient Impairments: Patients often have impaired vision, reduced tactile sensation or arthritis. The daily bins snap into the frame and have a large "push" button to eject the tray. The tray has three chambers (AM, Noon, PM) with individual doors allowing easy access the pills. The doors have large easy to grab handles.

Monitoring: The tray is placed in the PillStation®and a picture is taken of the pills by a camera and lighting that move behind the seven daily bins. This creates a recorded picture of the tray contents that is sent by a telephone connection to a call center. The call center then quickly reviews the tray status and compares this to the plan.

Communications: A speaker, microphone, graphical LCD and signal light provide easy to understand communications. One button push connects the patient to the call center for help. Positive messages arrive when a patient is on-plan. Alerts are sent when patient deviates from the plan.

Soteira Surgical Instruments

Bleck Design Group, Soteira Drill Reamer Combo

 

This product drills and reams a cavity in a fractured vertebra to allow the placement of a stent which is then filled with injected adhesive.

An Ergonomic and Cost Problem: The original design performed the drilling and reaming with required precision and control. However this required two devices, careful set-up between drilling and reaming, and was costly. Training was time consuming as each language required new instructions.

Project Summary: Bleck Design Group combined the original two tools into one, improved the ergonomics and reduced cost over 50%. The original 15 steps were reduced to 4. In the new design, each action has a distinct control, with interlocks for safety.

Ergonomic Task Analysis and Mechanism Creation: The concept development focused on the external perception of the controls and creating corresponding internal mechanisms. The original threaded mechanisms were actuated with new cams,clutches and simple transmissions.

Transforming the Concept to Production: From concept to the first full prototype was four months. In six months the new design was validated and ready for clinical use.. The prototype was designed for low volume production and allowed Soteira to meet their market introduction. 

Production Design: The production design followed the initial pilot production. We released a revised version for tooling and supported the contract manufacturer through final validation.
