BOLT, DRILL and Accessories for Neuromonitoring

Implantation and Catheter Accessories

RAUMEDIC offers various accessories for the implantation of all catheters in the NEUROVENT family. In addition to accessories that are used directly for implanting the catheter, RAUMEDIC also offers the cables needed to transfer the measured parameters from the catheter to the hospital’s patient monitors.

DRILL KIT

DRILL KIT for the precise penetration of the cranium

To implant the catheter, the skull is penetrated with a Drill and the suitable DRILL bit. The DRILL bit size is selected to match the diameter of the catheter.

The DRILL bit is disposable and is for single use only as bone is dense and will cause the DRILL bit to become dull. If the DRILL bit is dull, the friction creates high temperatures and will lead to thermal damage in the bone, which will negatively affect the healing of the bone.

The DRILL KIT matches the diameter of the measuring catheter and is offered in versions CH5 for parenchyma catheters or CH9 for ventricular catheters. Each DRILL KIT comes with an Allen key to adjust the depth of the stopper on the DRILL.

BOLT KIT

BOLT KIT with accessories for the positioning of the catheter

To safely position the measuring catheter, a BOLT is screwed into the drilled hole. A Screwing in tool is used to fix the BOLT in the skull creating a tight seal. The catheter is also firmly secured into the BOLT with the help of a flexible sealing cap. This way, the catheter is provided with a certain strain relief to protect it from damage caused by the patient's movements.

The BOLT KIT is also available in two versions: CH5 (for parenchyma catheters) and CH9 (for ventricular catheters).

The BOLT KIT PTO 2L is a 2 lumen BOLT, which provides secure positioning of the NEUROVENT-PTO 2L  and microdialysis catheters through a single access port.

A Screwing in tool is used to position the BOLT into the skull creating a tight seal. Because of the low height and the flexible lumens above the bone screw the BOLT KIT PTO 2L is ideally suited for clinical applications. The dimension of the BOLT KIT PTO 2L is CH9.

Spliceable Tunneling Sleeve

Spliceable Tunneling Sleeve for the implantation of the catheter

As an alternative to the safe positioning of the intracranial catheters, a tunnel can be created below the scalp. With the help of the Spliceable Tunneling Sleeve, the catheter is pulled through the tunnel then the sleeve is spliced and removed leaving the catheter in place. The subcutaneous tissue surrounds the catheter very tightly; however it creates a more significant surgical trauma than the BOLT. The Spliceable Tunneling Sleeve is available in two versions: CH8 for parenchyma catheters and CH12 for ventricular catheters.

Connection Cable ICP-TEMP-Cable and ICP-TEMP-Adapter

ICP-TEMP-Adapter
ICP-TEMP-Adapter directly connects to the temperature port on the patient monitor

Depending on which catheter is implanted different cables are available to directly connect to the temperature and pressure ports on the patient monitors. These connection cables interface with all commonly used patient monitors. For transferring the ICP (intracranial pressure) to the patient monitor, the ICP-TEMP-Cable is required; which serves as an extension from the catheter to the patient monitor. For transferring the temperature parameter, the ICP-TEMP-Adapter is required (Philips/HP monitor requires a specific ICP-TEMP-Adapter).

Zero-Point Simulator NPS2

The Zero-Point Simulator NPS2 is attached directly to the pressure port of the patient monitor. All RAUMEDIC catheters are calibrated in the manufacturing process to eliminate possible errors that can occur when zeroing the catheter. The Zero-Point Simulator NPS2 is used to transfer the 'zero' to the patient monitor.

NPS3 Mobile Transport Unit

The NPS3 is a battery operated device for continued portable pressure measurement while the patient is being transferred. The ICP-TEMP-Cable can quickly and easily be disconnected from the NPS2 and connected to NPS3.

Cable PTO and Cable LWL

The Cable PTO and the Cable LWL are necessary for measuring oxygen partial pressure, and to display the measured values. The Cable LWL transfers the oxygen signal and the Cable PTO transfers the ICP (intracranial pressure) and temperature signal to the MPR2 logO DATALOGGER.
