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.
Capteur unitaire qui comprend un cadre sur lequel on peut disposer des éléments électriques et optiques, et un revêtement, du type revêtement de surmoulage, autour du cadre. Ce capteur comporte une ou plusieurs structures de diaphragme constituées à partir de minces parties du matériau de revêtement et placées généralement autour d'au moins un des éléments optiques. La ou les structures en question permettent de séparer les éléments optiques, par exemple par application d'une force opposée aux côtés latéraux du capteur, de sorte que le capteur puisse être placé sur un patient. Le capteur peut ainsi être placé sur un doigt, un doigt de pied, une oreille, etc. du patient, permettant d'effectuer des mesures de sphygmo-oxymétrie ou d'autres mesures physiologiques.
