A bi-stable sensor is provided that includes a frame upon which electrical and optical components may be disposed and a coating, such as an overmold coating, provided about the frame. A resistance-providing component is provided integral with or external to the coated bi-stable sensor such that the bi-stable sensor has two mechanically stable configurations that may be transitioned between by overcoming the resistance provided by the resistance-providing component and/or the by the coating. In one embodiment, the resistance-providing component comprises an elastic band provided about a hinge of the frame, either within or external to the coating. In one embodiment, the sensor may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements.

Bi-stable medical sensor and technique for using the same

A method for manufacturing a sensor is provided. The method includes providing a frame having a loop structure, and covering the frame with a coating material to provide a sensor body having at least one diaphragm structure. The one or more diaphragm structures of the sensor body bias an emitter housing and a detector housing of the frame toward one another. The sensor may be placed on a patient's finger, toe, and so forth, to obtain pulse oximetry or other physiological measurements.

Methods of manufacturing a compliant diaphragm medical sensor

A medical sensor may be adapted to account for factors that cause irregularities in pulse oximetry measurements or other spectrophotemetric measurements. Sensors are provided with surface features that reduce the amount of outside light or shunted light that impinge the detecting elements of the sensor. The sensor is adapted to reduce the effect of outside light or shunted light on pulse oximetry measurements.

Medical sensor and technique for using the same

A sensor assembly is provided that includes a frame having a loop structure. An emitter and detector are disposed on opposite sides of the loop structure. A coating is provided over the frame. The coating includes at least one diaphragm structure disposed such that at least one of the emitter and detector can move along an axis running between the emitter and detector. The sensor may thereby be placed on a patient's finger, toe, and so forth to obtain pulse oximetry or other physiological measurements. A sensor frame and method of manufacturing the frame are also provided.

Compliant diaphragm medical sensor and technique for using the same

A sensor assembly is provided that includes a skeletal frame comprising first and second portions configured to move relative to one another. At least one physiological sensor is attached to the frame. A coating is provided over the frame and the at least one physiological sensor to form the sensor assembly. The sensor may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements. Methods for manufacturing and using a sensor are also provided as is a method for manufacturing a sensor body.

A sensor assembly is provided that includes a frame having two or more structural supports. A coating is provided over the frame. The coating has at least one deformable region disposed between the two or more structural supports. The sensor assembly includes at least one optical component disposed within the at least one deformable region such that the at least one optical component can move relative to the two or more structural supports. In one embodiment, the sensor assembly may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements. Methods of manufacture and use of the sensor assembly are also provided.

Medical sensor having a deformable region and technique for using the same

A sensor assembly is provided that includes a frame having two or more structural supports. A coating is provided over the frame. The coating has at least one deformable region disposed between the two or more structural supports. As least one optical component is disposed within the at least one deformable region such that the at least one optical component can move relative to the two or more structural supports. A biasing component is attached to an end of the frame such that at least two different portions of the coated frame are biased closed in the absence of a sufficient opening force. The sensor may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements. A skeletal frame and a method for manufacturing a skeletal framework are also provided.

A unitary sensor is provided that includes a frame upon which electrical and optical components may be disposed and a coating, such as an overmolded coating provided about the frame. The unitary sensor includes one or more diaphragm structures formed from thin regions of the coating material and disposed generally about at least one of the optical components. The diaphragm structure or structures allow the optical components to be separated, such as by application of an opposing force to the lateral sides of the sensor, such that the sensor may be placed on a patient. The sensor may thereby be placed on a patient's finger, toe, and so forth to obtain pulse oximetry or other physiological measurements.

A unitary sensor is provided that includes a frame upon which electrical and optical components may be disposed and a coating, such as an overmolded coating provided about the frame. The unitary sensor includes a spring, such as a flat spring or torsion spring, provided on the frame that provides a closing force for the sensor. The sensor may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements.

A sensor assembly is provided that includes a frame having a first portion and a second portion connected by a hinge. An emitter and a detector are disposed on the frame. A coating is provided over the frame, the emitter and the detector to form a unitary sensor assembly. The sensor assembly also includes a resistance-providing component disposed generally about the hinge. In one embodiment, the sensor assembly may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements. A method of manufacturing the sensor assembly is also provided as is a method of cleaning a fluid-tight sensor assembly.

Unitary medical sensor assembly and technique for using the same

A sensor assembly is provided that includes a skeletal frame comprising a loop structure. The sensor assembly includes at least one physiological sensor attached to the loop structure. A coating is provided over the skeletal frame and the at least one physiological sensor to form a sensor assembly. The sensor may be placed on a patient's finger, toe, and so forth to obtain pulse oximetry or other physiological measurements. Methods of manufacturing the sensor and sensor body and of applying the sensor are also provided.
