Abstract: A chest non-invasive blood pressure detecting probe based on pulse wave transit time and a device thereof are provided. The detecting probe is attached closely to the skin surface of the human chest, and includes a probe body and a patch, which are of split type. The patch is attached and mounted, in a male-female fastener form, on the probe body for use, so that when the patch needs to be replaced, the patch is directly removed and replaced with a new patch, which is convenient for use. The detecting probe is portable and used for continuous dynamic real-time acquiring of the human aortic blood pressure, which is free from the constraints of lead wires, small and comfortable, and high in measuring precision.

Abstract: A wearable physiological measurement apparatus comprises a base, a bridge member, and a first and second support members movably coupled to the base and the bridge member to surround size-variable an opening for accommodating a care giver's finger therein. A measurement device is coupled to the base and with a probe projecting toward the opening for contacting the finger for vital sign measurement and monitoring. Resilient members are coupled between the base, the bridge member and the first and second support members to bias the base, the bridge member and the first and second support members moving toward each other to grip the finger to maintain proper contact of the probe to the finger.

Abstract: The present invention discloses a dual optical path sensor module for collect human physiological signals based on photoplethysmography. The module includes a base, and a photoelectric receiver and two light source modules mounted on the base. The two light source modules are symmetrically disposed on two sides of the photoelectric receiver, and each light source module includes light sources with at least two wavelengths. A light shielding portion is further disposed on the base, the light shielding portion surrounds the photoelectric receiver, and there is an opening at the top of the light shielding portion, so that light emitted from the light source is received by the photoelectric receiver after the light is diffusely reflected by the human body tissue.

Abstract: Disclosed is a ring-type pulse oximeter, including a rigid ring body (1). A measurement unit (2) is arranged inside the rigid ring body (1), and an elastic device (3), a photodiode (4), and at least one light emitting diode (5) are protrudingly disposed on an inner circumferential surface of the rigid ring body (1). When the ring-type pulse oximeter is worn, the elastic device (3) is pressed, so that the photodiode (4) and the at least one light emitting diode (5) fit with a finger, light emitted by the light emitting diode (5) is attenuated by the finger, then received by the photodiode (4) and processed by the measurement unit (2) to calculate blood oxygen saturation. The ring-type pulse oximeter exerts a force on a portion of the finger, such that the finger maintains a tight fit to the photodiode (4) and the light-emitting diode (5), thereby providing a comfortable wearing experience as well as adaptability to different finger shapes, and improving measurement accuracy.
