Visual Pressure Control

A development by PAJUNK® and Prof. Dr. med. Dietmar Enk and Dr. med. Günter Michaelis


Visual detection of epidural resistance loss

As an alternative to tactile pressure control using a LOR syringe, Pajunk® has developed the VPC (Visual Pressure Control). This shows a loss of resistance even at low pressure drop and enables, in the interest of patient safety, an objective position check of the tip of the cannula when reaching the epidural space.

The operating principle

Initial situation: Skin puncture, connection

The VPC is pressurised by pushing the plunger forward. The pressure column (magnifying glass) rises.

The pressure column remains visible as long as tissue pressure remains at the tip of the cannula.

When the epidural space is reached, the characteristic loss of resistance becomes visible by a clearly recognisable drop of the pressure column in the magnifying glass of the capillary.

Advantages of VPC technology

Bimanual cannula guidance facilitates application, the piston can be released.
The pressure column shows the slightest pressure differences and enables a reliable position control of the cannula tip.

Reaching the epidural space (loss of resistance) is visualised, independent of tactile assessment.
Only small amounts of liquid are injected.

The law behind the technology

In the VPC syringe, the Boyle-Mariotte law is applied to visualise the achievement of the epidural space. This assumes that the product of gas volume and pressure is constant.
