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. |

| Claim: |
1. A noninvasive photoplethysmographic sensor platform for mobile animals comprising: A body encircling collar configured to encircle a subject animal body portion; A latching member on the collar to secure the collar around the animal; an emitter on the collar configured to be mounted adjacent the subject animal, the emitter having two light sources of distinct wavelengths; and a receiver on the collar configured to be mounted adjacent the subject mammal for detecting light from the emitter that has been toward tissue of the subject mammal. |
| Claim: |
2. The noninvasive photoplethysmographic sensor platform for mobile animals according to claim 1 wherein the body encircling collar is configured to fit around the neck, chest or abdomen of a mouse or rat. |
| Claim: |

| Claim: |
5. The noninvasive photoplethysmographic sensor platform for mobile animals according to claim 4 further including an accelerometer on the collar. |
| Claim: |
6. The noninvasive photoplethysmographic sensor platform for mobile animals according to claim 1 further including at least one further physiologic parameter sensor mounted on the collar. |
| Claim: |
7. The noninvasive photoplethysmographic sensor platform for mobile animals according to claim 1 further including a transmitter on the collar coupled to the emitter and the receiver. |
| Claim: |
8. The noninvasive photoplethysmographic sensor platform for mobile animals according to claim 1 further including additional sensors wherein the platform is configured to calculate an A-V gradient about the subject animals heart. |
| Claim: |
9. A method of obtaining noninvasive photoplethysmographic measurements from an animal comprising the steps of: Providing a body encircling base configured to substantially encircle one of the head, neck, chest or abdomen portion of the body of a subject animal, 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 substantially encircling one of the head, neck, chest or abdomen portion of the body of a subject animal; Obtaining photoplethysomgraphic measurements from the receiver on the base on the subject animal. |
| Claim: |
10. The method of obtaining noninvasive photoplethysmographic measurements according to claim 9 wherein the animal is an anesthetized rat or an anesthetized mouse. |
| Claim: |
11. The method of obtaining noninvasive photoplethysmographic measurements according to claim 9 wherein the base is secured around the neck of the animal. |
| Claim: |
12. The method of obtaining noninvasive photoplethysmographic measurements according to claim 9 wherein the base is secured around the chest of the animal. |
| Claim: |
13. The method of obtaining noninvasive photoplethysmographic measurements according to claim 12 further including calculating an A-V gradient about the subject animals heart. |
| Claim: |
14. The method of obtaining noninvasive photoplethysmographic measurements according to claim 9 further including the step of obtaining further physiologic measurements from at least one additional sensor mounted on the collar. |
| Claim: |
15. The method of obtaining noninvasive photoplethysmographic measurements according to claim 9 wherein the base is secured around the head of the animal. |
| Claim: |

| Claim: |
18. A neck mounted pulse oximetry sensor for an animal comprising: A neck encircling collar configured to encircle a subject animal body portion; A latching member on the collar to secure the body around the neck of the animal; an emitter on the body configured to be mounted adjacent the subject animal, the emitter having two light sources of distinct wavelengths; and a receiver on the body configured to be mounted adjacent the subject mammal for detecting light from the emitter that has been toward perfused tissue of the subject mammal. |
| Claim: |
19. The neck mounted pulse oximetry sensor for an animal according to claim 18 wherein the latching member is adjustable and is configured to secure the collar around the animal in at least one of a plurality of latching positions associated with different effective lengths of the collar. |
| Claim: |
20. The neck mounted pulse oximetry sensor for an animal according to claim 18 further including a controller coupled to the emitter and the receiver, wherein the controller is configured to perform pulse oximetry calculations based upon the light detected by the receiver. |
