Noninvasive photoplethysmographic sensor platform for mobile animals
First Claim
1. A method of obtaining noninvasive photoplethysmographic measurements from an animal, which is a mouse or a rat, comprising the steps of:
- Providing a body encircling base configured to encircle one of the head, neck, chest or abdomen portion of the body of a subject animal, which is a mouse or a rat, the base including an emitter on the body configured to be mounted adjacent the subject animal, the emitter having two light sources of distinct wavelength, and a receiver on the body configured to be mounted adjacent the subject animal for detecting light from the emitter that has been toward tissue of the subject animal;
Securing the base in a position encircling one of the head, neck, chest or abdomen portion of the body of a subject animal, which is a mouse or a rat;
Obtaining photoplethysomgraphic measurements from the receiver on the base on the subject animal which is a mouse or a rat.

Abstract
A noninvasive photoplethysmographic sensor platform for mobile animals such as small rodents, namely rats and mice is useful such as in a laboratory research environment. The noninvasive photoplethysmographic sensor platform may be a collar which provides an easily affixed, adjustable attachment mechanism that encircles the animal, such as the neck. The neck of the animal provides several particular advantages as a sensor mounting platform for photoplethysmographic sensors. For pulse oximetry, the neck location will provide significant blood flow under all conditions. For small mammals, such as rats and mice, transmittance pulse oximetry through the neck of the subject remains possible. The neck mounted collar also offers inherent bite resistance to the sensor platform.
