A patient-contact medical accessory is designed around three constraints at once: the material has to be safe on fragile skin, the geometry has to fit hardware the hospital already owns, and the whole part has to survive repeated cleaning or autoclaving.

Dignity & Empowerment's glow-in-the-dark nurse call cover — invented by clinical neuropsychologist Dr. Sharada Damaraju — went through that sequence with us: silicone and pigment trials, iterative fit prototypes, then DFM documentation and a first low-volume production run.

The client

When Dr. Sharada Damaraju, a clinical neuropsychologist, noticed how elderly and mobility-impaired patients struggled to locate their nurse call buttons, especially at night, she saw more than inconvenience; she saw a loss of independence and safety.
The standard white plastic button often blended with sheets and pillows, making it nearly invisible in low light. Patients would reach, strain, or even fall while trying to summon help.
Determined to solve this safety-critical issue, Dr. Damaraju founded Dignity & Empowerment with one mission: to give patients their control, comfort, and dignity back. She partnered with LA New Product Development Team (LA NPDT) to bring her idea to life through expert medical product development and healthcare product design and development.

The challenge

The cover had to fit nurse call handsets it was never designed for — several brands, all slightly different — without blocking a button or changing how the device is pressed. It also had to glow long enough to still be findable in the middle of the night after the room lights went out hours earlier.

When engineering meets empathy, innovation becomes healing.

Our solution

Our journey began with a vision, a simple yet powerful concept: a soft, hygienic, glow-in-the-dark silicone sleeve that slips over any standard nurse call device, making it easy to see and safe to touch.
We collaborated closely with Dr. Damaraju through every stage of healthcare product development. Multiple design iterations, prototype evaluations, and material trials were conducted to achieve the perfect balance of softness, durability, glow performance, and safety.
Through rapid prototyping and continuous feedback loops, we refined the geometry to fit existing devices seamlessly. The design included small collapsible bristles that reduce drag on fragile skin and provide subtle sensory feedback for grip and comfort.

Softness that protects. Visibility that empowers.

Materials and safety validation

Developing a healthcare product for patient contact required precision, cleanliness, and adherence to safety-critical product development standards. Every design choice, from material hardness (20 Shore A) to pigment ratios, was validated for usability, safety, and manufacturability.
We tested several formulations of medical-grade silicone and glow pigments to ensure visibility without compromising hygiene. The final product performs under sterilization and cleaning, and can withstand autoclave conditions. It’s an ideal combination of science, empathy, and engineering.

Engineered for safety. Designed for humanity.

    We prepared complete DFM documentation, selected tooling methods, and managed the first low-volume manufacturing run. This ensured repeatability, cost efficiency, and consistent quality control.
  4. 04

    Branding and logo design

    We created the Dignity & Empowerment brand identity, symbolizing safety, visibility, and compassion. The logo and color palette were designed to resonate with healthcare professionals and patients alike.
  5. 05

    Website and marketing support

    We developed website content, product descriptions, and imagery, and created educational materials that helped launch the company’s digital presence to reach hospitals, nursing homes, and care facilities.
  6. 06

    Packaging and instruction design

    Our design team produced clear packaging layouts and instruction manuals detailing installation, cleaning, and charging processes.

From concept to care, every detail matters.

The result

This collaboration between Dignity & Empowerment and LA NPDT exemplifies how innovation in healthcare product design and development can transform lives.
The Nurse Call Cover enables patients, especially the elderly and those with limited mobility, to locate help instantly. It reduces the risk of falls, injuries, and delayed responses, restoring dignity by allowing patients to act independently and confidently in their care environments.
Beyond individual benefit, hospitals and nursing facilities gain improved safety metrics, fewer incidents, and increased patient satisfaction.
By combining medical insight with technical expertise, this partnership turned empathy into engineering, and engineering into empowerment.

Designing dignity back into patient care.

How a patient-contact medical accessory gets developed

Every decision below was made on this project, in this order. Skipping one of them is what turns a promising clinical idea into a part that cannot be cleaned, cannot be molded, or cannot be sold.

  1. 1. Define the clinical failure you are removing

    The starting point was observed, not assumed: a white plastic call button disappears against white sheets at night, so patients reach, strain and sometimes fall. Naming the failure precisely sets the acceptance test — the device must be findable in the dark without being touched first.

  2. 2. Design to fit hardware you do not control

    Hospitals will not replace their call systems for an accessory. The cover was designed as a sleeve that slips over any standard nurse call device, so the geometry had to accommodate a family of existing shapes rather than one.

  3. 3. Trial materials before you trial form

    We tested several medical-grade silicone formulations and glow pigment ratios together, because pigment loading changes both brightness and durometer. The result landed at 20 Shore A — soft enough for fragile skin, firm enough to hold shape.

  4. 4. Prototype the human details

    Small collapsible bristles were added to reduce drag on thin skin and give tactile feedback for grip. Details like that only survive if they are printed and cast early, handled by real users, and revised across several iterations.

  5. 5. Validate against cleaning, not just use

    In a care setting, the cleaning cycle is the harshest load case. The final part was validated to perform under sterilization and cleaning and to withstand autoclave conditions, which constrained both the polymer and the pigment.

  6. 6. Prepare DFM, then run low volume first

    We produced complete DFM documentation, selected tooling methods and managed the first low-volume manufacturing run — proving repeatability and cost before scaling, and giving the company sellable units for hospital and nursing-home trials.

Questions about this project

Straight answers from the engineers who ran the build. Have a different question? Ask us directly.

Talk to an engineer
How long does it take to develop a medical accessory like this?

Products that sit outside the regulated device itself — sleeves, covers, holders — move much faster than the device they attach to, because the clinical hardware is unchanged. The schedule is driven by material trials and fit iterations rather than by submissions, so it behaves like a consumer program with medical-grade material discipline.

Why does silicone hardness matter so much?

Durometer sets whether a part protects skin or abrades it. Too soft and the sleeve deforms and slips off the button; too firm and it presses on thin skin. We converged on 20 Shore A by making parts at several hardnesses and having them handled, not by picking a number from a datasheet.

Can you handle manufacturing as well as design?

Yes. We prepared the DFM package, selected the tooling method and ran the first low-volume production batch in-house, which is usually the right first step: it proves the process and gives the company real inventory before committing to hard tooling.

Do you also handle branding and packaging for medical products?

On this project we did — brand identity, packaging layout and the instruction manual covering installation, cleaning and charging the glow material. Care facilities evaluate the whole package, and unclear instructions are a real adoption barrier for a product used by night staff.
