| 20100113902 | Small Bore Magnetic Resonance Imaging Photoplethysmographic Sensor - An efficient, effective, MRI compatible small bore MRI noninvasive photoplethysmographic sensor for animals such as small rodents, namely rats and mice. The photoplethysmographic sensor for animals comprising: a non-magnetic sensor coupling attachable to an animal; fiber optic cable coupled to the sensor coupling and configured to deliver a signal to and receive a signal from the animal tissue adjacent the sensor coupling; an opto-electical converter coupled to the fiber optic cable, the converter including a receiver coupled the fiber optic cable portion configured to receive a signal from the animal tissue and including an emitter coupled to the fiber optic portion configured to deliver a signal to the animal tissue; an electronic coupling extending from the opto-electric converter and configured to be coupled to the emitter and the receiver, wherein the electronic coupling is configured to extend outside of the MRI chamber; and a processor coupled to the electronic coupling. | 05-06-2010 |
| 20100160751 | PHOTOPLETHYSMOGRAPHIC SENSOR BASED BLOOD GAS MONITOR DEVICE FOR ANALYSIS, RESEARCH AND CALIBRATION IN AN EXTRACORPOREAL CIRCUIT OR EXTRACORPOREAL PULSE SIMULATION SYSTEM - A blood oxygenation monitoring device may comprise an extracorporeal pulse simulation system including one at least partially transparent blood holding element with a photoplethysmographic sensor coupled to the element and adapted to measure particular gas content of the blood. The system includes a pulse simulation mechanism configured to simulate pulsatile behavior of the blood within the element relative to the photoplethysmographic sensors. The blood holding element may be a reservoir, wherein the pulse simulation mechanism includes a magnetic stirrer and stir bar within the reservoir. The blood holding member may be flexible tubing having blood flow there through, wherein the pulse simulation mechanism is a peristaltic pump coupled to the tubing. The monitoring device can rapidly and accurately form oxygen dissociation curves. The monitoring device can be utilized in conjunction with a heart lung bypass machine or other extra corporeal circuit devices or can be a calibration tool for sensors. | 06-24-2010 |
| 20110137185 | Saddle Faced Small Animal Sensor Clip - A noninvasive photoplethysmographic sensor platform for small animals provides a spring biased sensor clip, wherein at least one side of the sensor clip is provided with a saddle faced clip face member. The saddle shape of the clip face member may have a hinge end, toward the hinge of the clip, which is longer in the longitudinal direction of the clip and shorter in depth than the distal end. The shorter distal end side (measured longitudinally) of this saddle shape facilitates the ability to align the transmitted and received light with the bone, while the overall saddle shape of the facing provides a physical grip to capture enough tissue to prevent the clip from relocating over time while it is attached to the limb. The shorter hinge end side (depth-wise) also allows the clip to close when it is fully assembled. The edges of the saddle shaped clip are preferably rounded off to prevent the contusions of the tissue that may result from long-term contact. This saddle faced feature works well on only one side of the clip. | 06-09-2011 |
| 20120004517 | BLOOD PRESSURE MONITOR AND PULSE OXIMETER SYSTEM FOR ANIMAL RESEARCH - An integrated blood pressure monitor and pulse oximeter system includes a blood flow occlusion member configured to selectively occlude blood flow through an appendage of the animal (e.g., the neck or tail); a sensor coupled to the blood flow occlusion member detecting a degree of operation thereof; Light sources coupled to the tail closer to the distal end of the tail than the tail blood flow occlusion member, and selectively directing light of two different wavelengths into the appendage; a light receiver coupled to the appendage and selectively receiving a signal associated with light directed into the appendage from the light sources; and a controller configured to selectively determine blood pressure parameters from the data and pulse oximeter parameters from the data. | 01-05-2012 |
