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 that are needed to transfer the measured parameters from the catheter to the hospital’s patient monitors.
To implant the catheter, the calvaria is penetrated with a DRILL and corresponding DRILL bit. The DRILL bit size is selected to match the diameter of the BOLT screw. The DRILL bit is disposable and for single use only, since it keeps its sharpness only for a short time due to the abrasive properties of the bone.
If the DRILL bit is dull, it creates high temperatures locally due to friction and thus leads to thermal damage in the bone, which will negatively affect the healing of the bone. The DRILL KIT matches the diameter of the BOLT screw and is offered for parenchyma and ventricular catheters.
Each DRILL KIT comes with an Allen key to adjust the depth of the stopper on the DRILL.
To safely position the measuring catheter, a BOLT is screwed into the drilled hole. By means of a screwing-in tool the BOLT is fixed in the skull and creates a sterile seal for the drilling hole. 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.
BOLT KIT PTO 2L
The BOLT KIT PTO 2L is a 2 lumen BOLT, which provides secure positioning of the NEUROVENT-PTO 2L and the microdialysis catheter through a single access port.
BOLT KIT PTO 2L guarantees a safe positioning of the measuring catheters in the drilling hole. By means of a screwing-in tool the BOLT is fixed in the skull and creates a sterile seal for the drilling hole. Because of the low height and the flexible lumens above the BOLT screw the BOLT KIT PTO 2L is ideally suited for clinical applications.
Spliceable Tunneling Sleeve
As an alternative to the safe positioning of the intracranial catheters, a tunnel can be created below the scalp. With the help of the RAUMEDIC 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
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 in hospitals. 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 additionally (as a jack plug; or for Philips/HP monitors in particular).
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.
