Laser Doppler Probes
Part #: TSD140, TSD142, TSD143, TSD144, TSD145, TSD146

The TSD140 series surface probes are designed for skin and exposed tissue blood flow monitoring. All surface probes are made from black Delrin. The signal delivery fiber intersects the probe body at a right angle, making the probes easy to secure to the skin or tissue surface. Surface probes are non-suturable, unless otherwise indicated. All surface probes have a 3-meter cable for connection to the LDF100C module.

Compatibility


TSD140 Probe: This robust and easy to handle probe is ideal for taking measurements of cutaneous blood flow anywhere on the skin surface.

TSD142 Digit Probe: This probe was specially developed for measuring microvascular skin blood flow in the digits; the curved geometry of these probes makes them ideal for studying conditions such as Raynaud’s disease.

TSD143 Miniature Probe—suturable: Particularly suitable for small animal work including various post-operative monitoring applications such as reconstructive surgery. Small and lightweight, suitable for noninvasive tissue surface blood flow monitoring and for semi-invasive monitoring of blood flow from muscle and internal organ surfaces. Tissue attachment via double-sided adhesive rings or by suture. (See TSD146 for non-suturable mini probe.)

  • Dimensions: Head diameter 12 mm, Head height 5 mm, Total probe length 3 m
  • Reusability: Unlimited

TSD144 Needle Probe: This needle probe is used when making microvascular blood flow measurements in relatively inaccessible areas with limited clearance. Typically, they are positioned using a micromanipulator clamp over soft tissues, such as brain and muscle.

TSD145 Micro-needle Probe: This micro-needle probe is designed for direct insertion and is frequently used for measuring either micro-vessel or microvascular blood flow within skin, muscle, tumor, and organ tissues. The fine diameters of these probes facilitate blood flow measurements from only a small number of capillaries.

All needle probes come with a 3-meter cable for connection to the LDF100C module.

TSD146 Miniature Probe: Particularly suitable for small animal work and general tissue surface monitoring. Small and lightweight, suitable for noninvasive tissue surface blood flow monitoring and for semi-invasive monitoring of blood flow from muscle and internal organ surfaces. Tissue attachment via double-sided adhesive rings. (See TSD143 for suturable mini probe.)

  • Dimensions: Head diameter 12 mm, Head height 5 mm, Total probe length 3 m
  • Reusability: Unlimited
