Dedicated Blood Perfusion probes

A choice of probe types are available to suit a wide range of blood perfusion monitoring applications, as illustrated below.

 

        
   
     
     
       
     
 
  Surface probes
For microvascular blood perfusion monitoring from the surface of skin and organs. These probes comprise a black plastic body providing right-angled blood perfusion monitoring. Surface probes can be secured to skin using our double-sided adhesive rings (see Accessories, below). Since our surface probes do not contain metallic components they are entirely MRI compatible.		  


MSP100XP
Standard surface probe
These robust and easy-to-handle probes are ideal for measurements of cutaneous blood perfusion anywhere on the skin surface.


MSP110XP
Digit surface probe
Specifically developed for measuring cutaneous blood perfusion in the digits, the curved geometry of these probes make them ideal for studying conditions such as Raynaud's disease.


MSP300XP
Miniature surface probe (suturable)
Small and lightweight, suitable for non-invasive skin monitoring and for semi-invasive monitoring from muscle and internal organ surfaces. Tissue attachment via double-sided adhesive rings (below); alternatively this probe can be sutured onto the tissue. 


MSP310XP
Miniature surface probe (non-suturable)
Small and lightweight, suitable for non-invasive skin monitoring and for semi-invasive monitoring from muscle and internal organ surfaces. Tissue attachment via double-sided adhesive rings (below). 

   
  Needle probes
For invasive or non-invasive tissue blood perfusion monitoring in difficult to access tissue regions. These probes utilise medical grade stainless steel.		  


MNP100XP
Standard needle probe
For microvascular blood perfusion measurements in relatively inaccessible areas with limited clearance. Typically positioned using an external clamp.  
 
Approx. 19 gauge surgical steel shaft. Custom shaft lengths available to order.


MNP110XP
Fine needle probe
This micro-needle probe has been developed for minimal tissue trauma during invasive insertion and is frequently used for measuring microvascular blood perfusion within, muscle, tumors, internal organs and brain tissues.  
 
Approx. 25 gauge surgical steel shaft. Custom shaft lengths available to order.

 
   
  Specialised probes/Accessories
  

MNP150XP
Bent tip needle probe
An angled probe tip facilitates blood perfusion measurements in specialist applications such as gingiva and nasal mucosa. Typically positioned using an external clamp. 
 
Approx. 19 gauge surgical steel shaft. Custom shaft lengths and configurations available to order.


MSF100XP
Single-fibre implantable probe
This light and flexible probe consists of a 0.5mm diameter polymethyl methacrylate (plastic) fibre with a standard length of 30cm. Particularly useful for chronic implantation, the MSF100XP can be directly inserted into tissue using a standard 22G i.d. cannula. The extra light coupling bead minimizes the total weight of the implanted probe. Flow measurements are made by attaching the MSF Driver (MSFD XP - below). 


MSFD XP
Dedicated connecting adapter for the MSF100XP  implantable probe
The MSF Driver is a precision-machined coupling system designed to interface the MSF100XP probe with the monitor. The MSF100XP probe coupling bead is locked into position by a simple turn of the MSF Driver head.
 
Manufactured from specialist polymer and containing no metallic parts, the MSF Driver is fully MRI compatible.


MH-05 / MH-10
Miniature holders for secure attachment of MNP100XP needle probe
These miniature plastic holders are specially designed for use with a shortened version of the MNP100XP needle probe for the measurement of local cerebral cortex perfusion in models of stroke (e.g. MCAO). The holders can be directly attached to bone (skull) using cyanoacrylate or rapid-setting epoxy glues and provide a very secure hold for the probe.

MSP140AR
Double-sided adhesive rings for MSP300 surface probes
These specialist double-sided adhesive rings provide a practical solution to securely attaching the MSP300 surface probe types to dry skin or internal organ surfaces.

CAL KIT
Calibration kit for perfusion probes
A Motility Standard comprising a solution of microspheres at a precisely controlled concentration and a probe positioning device together ensure highly reproducible perfusion probe calibration (required where probes cannot be supplied pre-calibrated).
 
   
Quality Statement: Every Oxford Optronix probe is manufactured to exacting quality standards to ensure reliability, durability and reproducible performance during operation. Schematics depicted are for illustrative purposes only and do not constitute a specification. Our monitors and probes do NOT possess regulatory approval for human applications.
