A clip-style pulse sensor may be adapted to apply limited, even pressure to a patient's tissue. A clip-style sensor is provided that reduces motion artifacts by exerting limited, uniform pressure to the patient tissue to reduce tissue exsanguination. Further, such a sensor provides a secure fit whil
A clip-style pulse sensor may be adapted to apply limited, even pressure to a patient's tissue. A clip-style sensor is provided that reduces motion artifacts by exerting limited, uniform pressure to the patient tissue to reduce tissue exsanguination. Further, such a sensor provides a secure fit while avoiding discomfort for the wearer.
1. A sensor adapted to be applied to a patient's tissue comprising: a sensor body having a first portion and a second portion biased towards one another by a spring force;a resilient material disposed on the first portion of the sensor body; at least one sensing element disposed on a substrate, wher
1. A sensor adapted to be applied to a patient's tissue comprising: a sensor body having a first portion and a second portion biased towards one another by a spring force;a resilient material disposed on the first portion of the sensor body; at least one sensing element disposed on a substrate, wherein the substrate is associated with an opposing surface of the resilient material such that the resilient material is between the substrate and the sensor body; anda stopping element configured to contact the first portion and the second portion when the sensor is applied to the patient's tissue, wherein the stopping element is capable of establishing a minimum distance between the first portion and the second portion and wherein a portion of the spring force is configured to be absorbed by the resilient material when the sensor is applied to the patient's tissue such that the sensor body applies a pressure that is sufficient to overcome a venous pressure but not an arterial pressure of the patient. 2. The sensor, as set forth in claim 1, wherein the stopping element comprises a rigid bar. 3. The sensor, as set forth in claim 1, wherein the stopping element comprises a plug. 4. The sensor, as set forth in claim 1, wherein the stopping element comprises a substantially inelastic strap. 5. The sensor, as set forth in claim 1, wherein the first portion and the second portion are coupled at an end of the sensor. 6. The sensor, as set forth in claim 1, wherein the resilient material comprises a foam. 7. The sensor, as set forth in claim 1, wherein the substrate is flexible. 8. The sensor, as set forth in claim 1, wherein the sensing element comprises an emitter and a detector. 9. The sensor, as set forth in claim 8, wherein the emitter comprises a light-emitting diode and the detector comprises a photodetector. 10. The sensor, as set forth in claim 1, wherein the sensor comprises at least one of a pulse oximetry sensor, a sensor for measuring a water fraction, or a combination thereof. 11. The sensor, as set forth in claim 1, wherein the sensor is configured to operate in transmission mode. 12. A pulse oximetry system comprising: a pulse oximetry monitor; anda pulse oximetry sensor adapted to be operatively coupled to the monitor, the sensor comprising:a sensor body having a first portion and a second portion biased towards one another by a spring force;a resilient material disposed on the first portion of the sensor body; at least one sensing element disposed on a substrate, wherein the substrate is associated with an opposing surface of the resilient material such that the resilient material is between the substrate and the sensor body; anda stopping element configured to contact the first portion and the second portion when the sensor is applied to a patient's tissue, wherein the stopping element is capable of establishing a minimum distance between the first portion and the second portion and wherein a portion of the spring force is configured to be absorbed by the resilient material when the sensor is applied to the patient's tissue such that the sensor body applies a pressure that is sufficient to overcome a venous pressure but not an arterial pressure of the patient. 13. The pulse oximetry system, as set forth in claim 12, wherein the sensing element comprises an emitter and wherein a detector is disposed on the second portion. 14. The pulse oximetry system, as set forth in claim 13, wherein detector is disposed on the second portion such that the emitter and the detector are not opposite each other. 15. A sensor adapted to be applied to a patient's tissue comprising: a sensor body having a first portion and a second portion biased towards one another by a spring force;a stopping element configured to contact the first portion and the second portion when the sensor is applied to the patient's tissue, wherein the stopping element is capable of establishing a minimum distance between the first portion and the second portion that results in the sensor body applying a pressure to the patient's tissue that is sufficient to overcome a venous pressure but not an arterial pressure of the patient; andat least one sensing element associated with the first portion of the sensor body. 16. The sensor, as set forth in claim 15, wherein the sensor is configured to be applied to an ear. 17. The sensor, as set forth in claim 15, wherein the sensor is configured to be applied to a finger. 18. The sensor, as set forth in claim 15, wherein the stopping element comprises a rigid bar or a plug. 19. The sensor, as set forth in claim 15, wherein the sensor is a pulse oximetry sensor. 20. The sensor, as set forth in claim 15, wherein the sensor is configured to operate in transmission mode.
