This utility model provides a pulse oximeter device, including: a probe assembly and a strap assembly; the probe assembly includes a body, an extension, and a detection element, the extension is connected to the end of the body, and the extension can deform to form a receiving space with the body for accommodating the measured part; the strap hole of the probe assembly penetrates the inner and outer surfaces of the extension in the thickness direction or penetrates the inner and outer surfaces of the body in the thickness direction; the size of the first strap of the strap assembly is smaller than the size of the second strap, and the strap hole allows the first strap to pass through but not the second strap; when the strap assembly is bound to the probe assembly, the first strap passes through the strap hole, and the first hook layer is detachably connected to the nap of the second strap, the side of the first strap facing the receiving space is blocked by the body or the extension and isolated from the receiving space, and the second strap is wrapped around the outer surfaces of the body and the extension.

This utility model discloses a probe for a pulse oximeter, relating to the field of probes. It includes a rubber adhesive with a rough edge on one side and a barbed edge on the other. A sensor is housed inside the rubber adhesive, and a wire is fixedly mounted on one side of the sensor. Rotating protrusions are mounted on both sides of the wire, and a mounting block is movably mounted within each rotating protrusion. One end of the mounting block is fitted with a rubber sleeve. This utility model solves the problem of poor performance in existing pulse oximeter probes. By incorporating a rubber adhesive, with adhesive at one end of the side where the sensor light-emitting block and sensor receiving block are located, and a rough edge on the other end, and a barbed edge on the other side, the protective film on the adhesive side can be removed when the probe needs to be installed on the patient's fingertip.

An adaptive gas mixture controller system. A pulse oximeter interface receives pulse oximeter data. A gas blender interface communicates with a separate externally connected gas blender. A processor receives pulse oximeter data via the pulse oximeter interface and outputs data to the gas blender interface for adaptive feedback control of the gas mixture based upon the SpO2 level signals from the pulse oximeter interface. When the processor receives data from the gas blender indicating that the gas mixture has been manually changed, enters a manual override mode and halts sending adaptive feedback control signals to the gas blender. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

During childbirth process, trauma to an infant can readily arise, ultimately resulting in fetal hypoxia, academia, and brain damage. Such unfavorable conditions can be prevented by measuring the fetus' blood-oxygen level and heart rate. Without a fetal pulse oximeters, blood oxygen level cannot be monitored non-invasively reliably, which reduces the chance for birth complications to be recognized in time. A noninvasive system to implement such goals and maximize the potential welfare of the fetus may include devices to measure oxygen saturation of hemoglobin (SpO2). Such a device may be an oxy probe that uses a trans-reflective method of SpO2 measurement where oxygen saturation data can be transmitted through wire, fiber optics, and or using a radio frequency link, fetal monitor data can be analyzed, compared to existing data base, and or transmitted via radio waves or internet.
