A company built around a single, unglamorous idea: making rapid tests actually defensible.

Infection screening in skilled nursing was built for a world that no longer exists: staffed floors, watched tests, paper logs nobody disputes. The reality on the ground is different.

Understaffed facilities. Rapid lateral flow tests (COVID, flu, RSV, strep) that can be reused, swapped, or pre-contaminated. A “witness” column that collapses into a signature the moment a CMS surveyor or a plaintiff’s attorney actually reads it. HAI liability mounting with every test nobody can prove was real.

VynMed builds the missing layer: point-of-care authentication that verifies a rapid infection strip is genuine in seconds, fingerprints the chain of custody, and produces the forensic record regulators and lawyers ask for, without rewriting the way a facility already runs.

The record a Director of Nursing can actually hand to a surveyor, an attorney, or a family in the same week. Signed, timestamped, and impossible to reconstruct after the fact.

What we build

VynScan is a patented, single-button countertop device. Staff insert a rapid lateral flow infection test strip (COVID, flu, RSV, strep). A patented pre-scan authenticates the strip itself, flagging pre-used, swapped, or tampered material before anything gets logged. The device then photographs the strip under controlled lighting and timing, and stores a cryptographically signed record automatically. Staff read the result the way they always have, per the test's instructions.

The underlying verification method is protected by U.S. Patent 12,308,098 B1, issued to VynMed’s founder. No lab integration. No new compliance SOP. Under-a-minute hands-on time for the nurse on the floor. It works with the rapid infection strips a facility already stocks, so there is nothing new to buy.

Who we build it for

VynMed exists for the people who get the call when a test result is contested: Directors of Nursing, compliance officers, medical directors, and facility administrators at skilled nursing and long-term care communities. The people whose job is to hand a clean, defensible record to a CMS surveyor, a state board, or an attorney, and whose liability begins the moment that record doesn’t exist.

The founder

Walter George Bischoff Jr, Founder & CEO

Walter’s stepfather died in a rehab facility early in COVID. Fear drove him out before his recovery was complete. Years later, Walter got sick after a social gathering and had a sudden thought: why couldn’t we have tested everyone before we hung out? A rapid test would have taken thirty seconds. The honest answer was that there was no way to make that test defensible once it was done.

A chemical engineer by training (Villanova BS, licensed PE in North Carolina), Walter spent eighteen years in power generation at major regulated utilities on the East Coast, managing capital projects and grid resilience. He taught himself to code. He learned PCB design. He built hardware. And he spent three years designing, filing, and prosecuting a patent that no one else had built: a method that authenticates rapid lateral flow strips in seconds, fingerprints the chain of custody, and produces the record a facility actually needs.

The first prototype was full of wires and janky. Today it captures a clean, timestamped record of an infection strip that a regulator can follow. It doesn’t add work to the nurse’s job. It takes the burden of proof off the staff, so they can focus on care.

Walter is the sole inventor named on U.S. Patent 12,308,098 B1. The patent survived a prior art challenge from a large foundation with deep resources. He conceived the verification method, filed and prosecuted the patent to grant, and leads VynMed’s product, regulatory, and commercial direction from Henderson, Nevada.
