SaniGuard is a patient isolation appliance used to protect healthcare workers whilst simultaneously reducing the time a patient needs to stay in hospital by providing better respiratory treatment. This low-cost and easy to implement solution creates a safe, sterile environment that separates infected patients from their carers. It's essentially a negative pressure cleanroom for a hospital bed. It constantly delivers HEPA filtered and UV-C disinfected air into a "bed enveloping bubble". The air inside the bubble is constantly replaced with clean air at a rate of more than 15 air changes per hours. It also HEPA filters and UV-C disinfects the contaminated air before discharge.
Air pressure in the envelope is automatically maintained so that contaminated air inside the envelop does not escape, even when care providers are working on the patient. UV-C light are also available for regularly disinfecting the bed's outer linen, thus further reducing the risk if surface to surface pathogen transfer.
Placing a patient into the "tent" is done by unzipping the panels and wheeling in the bed. When in place simply zip-up the panels and press the START button. Airflow will immediately start and self regulate to maintain a slight negative pressure in the "tent".
IV lines, oxygen tubes and monitor leads enter the "tent" via zipped slits. Hands-on attention, provision of medication and food, as well as attending to hygiene needs is all delivered via the zipper openings. As the zipper opening size is increased the airflow will automatically adjust to prevent air escaping the "tent". When the system approaches a point where air escape is imminent, a visual (AMBER light) and audible warning will be given to indicate that the service delivery opening should be closed as soon as possible. If at any stage negative pressure has not been maintained for a period longer than 15 seconds, then a visual (RED light) and audible warning will be given.
SaniGuard is intuitively easy to operate. Air flow and pressure control is fully automated with industry trusted sensors and controllers. Historical performance data can easily be retrieved and reviewed via the local LED display panel or remotely via web portal (optional).
Patient comfort plays a significant role in how well and how fast a patient recovers. Therefore SaniGuard been designed to be the most comfortable isolation pod on the market, while delivering better respiratory treatment for patients and the best protection for healthcare staff.
The enclosure is sufficently large such that patients don't feel claustrophobic or as if they're smothered in cling-wrap. The clear plastic is kept taut and well away from the patient, making it appear almost invisible.
SaniGuard employs leading edge fan, accoustic and air distribution technologies to ensure whisper quiet operation, allowing the patient to rest more easily
Not being able to have family and friends visit adds stress to patients in hospital isolation. Therefore SaniGuard has USB ports in the head-end plenum that allows patients keep their phone and tablet PC fully charged. The foot-end plenum (optionally) has a smart TV that provides access to free-to-air TV, Netflix and the internet. It also accommodates screen mirroring from the patient's smart phone or tablet PC. The inclusion of these technology items allows the patient to stay connected with their loved ones which helps them feel more supported and less isolated.
The plastic "tent" is attached to the head-end and foot-end plenums via a Velcro bands. After the SaniGuard is vacated, the "tent" is detached, rolled up and inserted into its sealed cleaning container. Once in the container it can be safely transported to the room. Cleaning is done by unrolling the "tent" onto a cleaning frame. Then it's first disinfected by bathing in UV-C light for 10 minutes and then wiped down with isopropyl alcohol. After air drying the "tent" is placed into its sealed storage container in readiness for when it's next required.
The pressure drop across the ULPA filter elements are constantly monitored and automatically logged. When this pressure gets excessive, indicating the filter element is clogged, a visual (RED light) and audible warning will be given. Optionally, an email or SMS can be sent to a service technician. Typically these elements require replacement after approximately 4,000 hrs of in service operation. The system controller records operating run hours and will provide an alert at the 3,500 hours has been reached.
To also protect the filter replacement technician, the ULPA elements are bathed in UV-C light, thus ensuring that no active pathogens are present on the elements.
