What it is

Nine needles, one regulated feed.

Regenis is a cart-mounted delivery system for regenerative mesotherapy: a 13.3-inch touchscreen console, a 212 g handpiece, and a nine-needle array fed from a single negative-pressure line. Every needle draws from the same regulated supply.

Nine points, one application

The array covers the treatment area in one application, where manual injection delivers to one point at a time.

Specified for suspensions

Engineered for biostimulator suspensions — PDLLA, PLLA, PCL and CaHA — alongside conventional mesotherapy solutions.

Eight memory presets

Pressure and speed are stored per procedure and recalled from memory. Negative pressure is adjustable across ten levels, up to 90 kPa.

The failure

Suspensions block needles specified for solutions.

Biostimulators are suspensions of solid microspheres, not solutions. Where the hub narrows into the cannula, those microspheres can pack and bridge across the opening.

Partial occlusion

Flow falls without stopping, so the amount delivered stops matching the amount set.

Complete occlusion

Delivery stops mid-procedure and the needle has to be changed.

Why it happens

Solid particles, mixed by hand.

Biostimulator microspheres are solid and denser than their carrier, so they settle. How thoroughly a syringe is mixed by hand decides how evenly the dose is distributed, and that varies between operators and between passes.

X-ray of syringe contents after five mixing passes and after ten — X-ray of syringe contents after five mixing passes (left) and ten (right). Hand mixing does not distribute microspheres consistently. Manufacturer data, Hertz Biotechnology (Shenzhen).

Suspension, not solution

Particle size

Commonly cited at 20–50 µm. Published literature puts commercial biostimulator microparticles predominantly at 20–80 µm.

Operator-dependent

Mixing passes

The X-ray shows the same syringe format after five mixing passes and after ten. Distribution differs visibly between the two.

What's different

Non-clogging geometry, held in a closed loop.

9needles

One feed, nine bores

The array is fed from a single regulated line, so every needle draws from the same chamber rather than from nine separate fills.

5signals

Sensed on every shot

Negative pressure, thrust force, speed, current and torque, sampled at millisecond intervals by sensors in the handpiece.

4×ARM + NPU

Decided on the device

A quad-core ARM CPU with a dedicated AI processing unit runs injection planning, clogging warning and risk analysis on a real-time operating system.

Protected design

The anti-clogging mechanism is patented.

The delivery path is the subject of a granted Chinese utility-model patent held by the manufacturer. These are the filing details; the certificate itself is a Chinese-language document and is not reproduced here.

Application number: 202421307575.3
Filed: 7 June 2024
Title: Microsphere injection anti-clogging device
Holder: Hertz Biotechnology (Shenzhen) Co., Ltd.

A patent is an intellectual-property right. It is not a marketing authorisation and does not describe device performance.

Verifiable precision

The system says so when delivery is not nominal.

Nine needles share one regulated feed, so the treated area is covered in a single application. When the drive train meets resistance outside its expected envelope, the system raises a named alarm rather than continuing silently.
