See the dose before you deliver it.
Vividose® replaces the black plunger tip — the part that disappears against black barrel marks — with a fluorescent seal and fill indicators sized to that seal.

The reading problem
Black on black is where a dose gets misread.
A conventional syringe asks you to find the edge of a black seal against black graduation marks. That edge is the entire measurement. It is harder for aging clinicians, for patients and caregivers at home, and in low light.
Vividose keeps the barrel clinicians already know and changes the surface that has to be read: the seal, plus an indicator that shows when that seal is on the line.
See the four stepsConventional
Black on black
The seal and the mark are the same color. The edge you are supposed to read disappears into the line.
Vividose
Color in the window
The fluorescent seal fills the indicator. The target volume is a color you can see, not a guess at a black edge.

How it works
Color confirms the line.
01
Draw
Retract the plunger. A fluorescent seal, not a black tip, rides at the leading edge of the dose.
02
Read
The barrel carries volume lines, numbers, and fill indicators sized to the bevel of the seal.
03
Confirm
Align the seal so its color is visible inside the indicator. That is the dose line.
04
Deliver
Depress the plunger and deliver through the needle, connector, or tube.
Seal colors
Pink, orange, yellow, and green.
Product materials describe fluorescent pink, green, orange, and yellow seals. Sample seals were specified for 5 ml. Disposable syringes were described in 3, 5, or 10 cc with a 1½-inch needle.
- Fluorescent pink
- Fluorescent orange
- Fluorescent yellow
- Fluorescent green
The patent disclosure also describes red, purple, and blue, and glow-in-the-dark seals, as further embodiments. Those are not offered products.
Who it is for
A clearer line for the person holding the syringe.
Clinicians
The idea started in IV therapy, where a clinician drawing a high volume of syringe doses found black tips against black marks harder to read with age.
Patients
People measuring their own injections — insulin, allergy treatments, fertility medicines — often do it at home, in ordinary light, sometimes with aging eyesight.
Caregivers
Parents and other caregivers measure a dose for someone else. A seal you can see is a clearer check than guessing where a black tip ends.
Hospitals and suppliers
A small number of companies supply syringes in bulk, and the plunger tip has had little reason to change. This is a specific fix for the moment of reading the line.
In the team’s prototype comparisons, fluorescent seals against black markings were easier to recognize than black tips. That is a design observation, not a clinical trial, and we do not publish error-reduction statistics.
For partners
Issued patent. Open conversation on making it.
Treble Innovations is looking for syringe manufacturers, licensees, distributors, hospital partners, and investors. The invention is issued. The finished, regulated product is not.
Manufacture
Established syringe makers. Prototyping so far is color, markings, and early molds.
License
The marketing materials invite licensing requests for the patented system.
Distribute
Hospital supply and syringe distribution, including evaluation conversations.
Invest
Capital for patient-ready prototypes, color and marking tests, and the regulatory path.
FAQ
Straight answers.
Is Vividose FDA-cleared?
No. Vividose is in development. Project planning has included FDA establishment registration and a 510(k) premarket notification. There is no clearance number and no approval to report. Nothing on this site is a clearance, an approval, or a clinical-outcome claim.
Can I order syringes here?
This website is not a store. A 2021 product sheet described sample bags of 5 ml seals in fluorescent pink, green, orange, and yellow, and disposable syringes in 3, 5, and 10 cc with a 1½-inch needle, and it invited trial orders by phone or email. Treat that sheet as historical. Current availability and price are not listed because those terms may be out of date. Send a note through the interest form.
What problem is it meant to solve?
Misreading the dose line. A conventional plunger ends in a black seal against black barrel marks. Vividose uses a fluorescent seal and fill indicators sized to that seal, so the alignment is something you can see — including for people with reduced vision, and in low light.
Who is it for?
Clinicians giving injectables, hospitals and clinics, patients who measure their own injections (including insulin, allergy treatments, and fertility medicines), and caregivers. Manufacturers, distributors, licensees, and investors are the people we most want to hear from.
