NRFit: Eliminating Missed Connections

NRFit is a new type of medical connector used for neuraxial and major regional anesthesia applications and is defined by ISO 80369-6. NRFit intends to increase patient safety by eliminating wrong route connections between patient supply lines that administer a variety of medications, nutrition, and other lifesaving fluids. Currently the universally compatible connector for all these supply lines is called a Luer connector, which has been identified as one of the main reasons for medication errors due to wrong route injections.

As the leading manufacturer in Regional Anesthesia, PAJUNK® offers its entire product portfolio for Neuraxial, major Regional Anesthesia, Wound Infiltration well as Lumbar Puncture applications in accordance with ISO 80369-6.

Optimal ultrasound visualization

Increased patient safety due to optimal vizualisation under ultrasound: Pajunk’s Cornerstone Reflectors

Pajunk’s patented Cornerstone reflectors (three-dimensional pyramid-like embossing along the first 20mm of the needle) make the needle shaft much easier to see and allow for optimized needle vizualization at any angle under ultrasound.1,2,3 They are key to the echogenicity of many Pajunk products.

Several independent studies have confirmed: SonoPlex® has revolutionized the Ultrasound Guided Puncture.

Reduce risk of nerve damage

Reducing Risk of Nerve Damage with NerveGuard

Ultrasound-guided localization of peripheral nerves and the associated real-time visualization provide crucial benefits in regional anesthesia.1 Nonetheless, it is clear that this does not eliminate the incidence of permanent nerve damage.2 Even in combination with nerve stimulation, intrafascicular injections cannot be ruled out.1,3,4,5

The causes include incorrect positioning of the needle along with exceeding critical injection pressures. With the NerveGuard, developed by Pajunk, the injection pressure is automatically limited to decrease the risk nerve damage.

Visual indication of 'Loss of Resistance'

EpiLong VPC for Visual Indication of Loss of Resistance (LOR)

There are different ways to find the epidural space including hanging drop and loss of resistance. These are associated with various risks, which makes it difficult to find.

The EpiLong VPC offers a visual indication of Loss of Resistance during epidural procedures. The EpiLong VPC is a reliable alternative to the conventional LOR technique, by visually indicating even the smallest pressure change resulting in a more objective needle tip placement and increased patient safety.

Catheter over Needle (CON) technique reduces the risk of leakage and minimizes catheter dislocation

Reduce risk of leakage

Catheter over Needle (CON) technique reduces the risk of leakage and minimizes catheter dislocation

Dr. Ban Tsui with Pajunk developed E-Cath and E-Cath Plus to address the complex challenges of Continuous Nerve Blocks (CNBs): catheter kinking, leakage, migration and dislocation. The E-Cath uses new Catheter-Over-Needle technology and requires the same skillset as performing a single shot block.

It is faster, safer and enables more reliable continuous nerve blocks with a reduction of workload during postoperative pain management.

It's time to change the needle for Lumbar Puncture

Reduce the risk of PLPH during Lumbar Puncture

For decades clinicians performing lumbar punctures had to battle the issues of Post Lumbar Puncture Headache (PLPH). One risk factor for post-lumbar puncture headaches is the use of a Quincke needle.6 With the introduction of the atraumatic Sprotte needle, the PLPH rates have been significantly reduced to allow for safer punctures and happier patients.

Sprotte Lumbar Advantages:
•Increases application safety
•Minimizes chance of PLPH 1, 2, 4, 5, 6, 7, 8
•Allows for quicker and optimized CSF flashback9
•Allows rapid detection of even the smallest quantities of CSF
•Minimizes chance of tissue coring
•Increases efficiency, reduces process and treatment costs 10
