Halo: Seizure-Safe Shower Harness

Halo is a shower harness designed to support individuals who experience seizures, enabling them to shower independently and safely. By preventing falls during a seizure, Halo provides users with peace of mind, enhances autonomy, and preserves dignity, while reducing the need for constant monitoring by caregivers or loved ones.

“For me, having seizures is like living in America where you never know who has a gun. It doesn’t mean everyone has a gun, and it doesn’t mean you’re always in danger, but you never know when you are.”

Seizures

Seizures can have a profound impact on daily life, creating both physical and emotional challenges for those affected. The unpredictability of seizures means individuals often face constant risks of injury and may require supervision or assistance. This dependence on others can significantly limit their sense of autonomy and independence. Furthermore, the stigma surrounding seizures can lead to feelings of embarrassment, isolation, and anxiety. As a result, individuals with seizures often face difficulties in participating fully in everyday activities, including work, social events, and even basic self-care. This highlights the urgent need for designs tailored to the unique needs of people with seizures.

People who experience seizures face significant risks of injury or even death, particularly when a seizure occurs in the shower. The combination of slippery surfaces and the potential for losing control of the body makes it a dangerous environment. To mitigate these risks, many individuals with frequent seizures take precautionary measures, such as showering with a family member, installing surveillance cameras, or leaving the door unlocked to allow for quick access if needed. While these precautions help ensure the person can be attended to in case of a seizure, they also come with considerable drawbacks. The constant need for supervision can severely limit a person’s autonomy and independence, as they rely on others to maintain their safety.

This dependence on caregivers or family members not only creates logistical challenges but also diminishes the individual’s sense of dignity and privacy. A place that is meant to provide solitude and personal care becomes an environment where the person is exposed and monitored, often leading to feelings of vulnerability. The emotional and psychological toll can be profound. Many individuals experience frustration and shame over needing assistance in such an intimate setting, which can prevent them from pursuing independent living arrangements. Fear of being alone, even in safe spaces, can lead to anxiety and a constant sense of insecurity. Furthermore, the burden of relying on others can cause feelings of guilt, as individuals may worry about inconveniencing their loved ones or becoming a source of emotional strain. These cumulative effects can limit opportunities for social and personal growth, impacting both the individual’s mental well-being and their relationships with those around them.

The Solution: Halo

Features

Coverage

The design of the Halo shower harness is intentionally minimalistic to ensure maximum comfort and freedom of movement. Unlike traditional mobility aids or safety devices, the harness covers only the essential areas, providing support without restricting the user’s range of motion.

Underarm Support

Extra padding under the arms is strategically placed to provide enhanced comfort and protection in case of a fall. The soft yet supportive padding helps distribute pressure evenly, allowing the user to feel secure while maintaining the flexibility to move freely. This design element enhances both safety and comfort, ensuring the user’s well-being in the shower.

Adjustable Straps

The Halo shower harness also features adjustable straps at both the waist and neckline, allowing for a customizable fit to suit individual body shapes and sizes. These straps enable the user to fine-tune the level of support and comfort, ensuring a secure yet flexible fit. They provide stability without restricting movement, while ensuring the harness stays in place during use.

Shoulder attachment point

Robust shoulder loops where the support straps attach provide a strong and secure connection point for the harness system. These loops are designed to offer an ideal leverage point, ensuring that the weight distribution remains balanced and effective. This strategic placement helps maintain the user’s stability, ensuring the harness performs effectively while minimizing strain on the body.

Retractable Locking Mechanism

The ropes connecting the user to the ceiling support system are flat, nylon straps that reduce risk of accidental strangulation. The ceiling support system is a retractable locking system that works similarly to a seatbelt. When extended slowly – such as when the user lowers bends down in the shower – the ropes retract with the user allowing them to adjust their position vertically. When in a lowered position, however, the spring mechanism in the ceiling support system applies gentle upwards pressure which influences the user to resume an upright position. This is both practical and safe as the harness cannot catch a fall once the user is already near the ground. When the user causes the ropes to extend at an accelerated rate – such as due to a fall – a component in the retractor is centrifugally displaced and jams the retractor, preventing the fall. Retracting the ropes once again causes this mechanism to unlock.

Materials

The adjustable straps and shoulder loops are made from nylon, which is durable and lightweight. The loops are covered with protective clear PVC tubing to reduce wear from friction on the nylon. The clear tubing also allows wear and tear on these load-bearing shoulder loops to be visible and quickly addressed.

A neoprene ‘wetsuit’ material envelopes the EVA foam interior throughout the harness. The foam gives shape to the harness, preventing it from getting easily tangled and difficult to don. Neoprene provides a soft and comfortable feel against the skin, reducing the risk of irritation during wear. Its water-resistant properties make it ideal for use in the shower, as it helps to prevent moisture absorption, keeping the harness lightweight and preventing it from becoming heavy or soggy.

The inner surface of the harness is lined with mesh polyester. It is lightweight and quick-drying, ensuring that the harness remains practical and functional, even in wet conditions, contributing to its overall comfort and durability.

The nylon adjustable straps and ABS release buckles are off-the-shelf components, which are cost-effective and easily accessible. The former is sewn in place with computerized sewing patterns such as a bar tack and box stitch. Smaller nylon strips are also sewn into the harness material at strategic locations around the waistline to hold the adjustable straps in place.
