摘要： A method of non-invasively monitoring hemoglobin concentration includes providing incident light to patient tissue at a first excitation wavelength. The method further includes monitoring a first emission response at a first emission wavelength, wherein the first emission wavelength is selected to correspond with a maximum of the emission response, and monitoring a second emission response at a second emission wavelength, wherein the second emission wavelength is selected to correspond with a minimum of the emission response. A hemoglobin concentration is calculated based on a ratio of the first emission response to the second emission response.

摘要： A method is described for testing the viability of a tissue of a patient for an anastomosis using a perfusion measuring device wherein the method may comprise: controlling at least one actuating structure of the perfusion measuring device to rapidly ramp up a force exerted on at least one test area of the tissue selected for an anastomosis, the force exerted on the at least one test area defining a local (systolic) perfusion pressure; and, during the ramp up of the force, the computer receiving a sensor signal from at least one sensor of the perfusion measuring device and a signal from a blood pressure device, the sensor signal being indicative of perfusion of blood through the micro vascularization in the first test area and the blood pressure signal being indicative of a general (systolic) blood pressure of the patient; controlling the first actuating structure to slowly ramp down the force exerted on the first test area, when the sensor signal signals the computer that the perfusion of the blood in the tissue of the first test area has stopped; and, during the ramp down of the force, the computer determining the local perfusion pressure at which the sensor signal indicates a start of perfusion of blood through the micro vascularization, the determined local perfusion pressure defining a reperfusion pressure value of the first test area; and, determining a prediction whether or not the tissue of the at least one test area is viable for an anastomosis on the basis of the local reperfusion pressure value of the at least one test area and the general systolic blood pressure value.

摘要： A surgical image acquisition system includes multiple illumination sources, each source emitting light at a specified wavelength, a light sensor to receive light reflected from a tissue sample illuminated by each of the illumination sources, and a computing system. The computing system may receive data from the light sensor when the tissue sample is illuminated by the illumination sources, and calculate structural data related to one or more characteristics of a structure within the tissue. The structural data may be a surface characteristic such as a surface roughness or a structure composition such as a collagen and elastin composition. The computer system may further transmit the structural data to a smart surgical device. The smart devices may include a smart stapler, a smart RF sealing device, or a smart ultrasonic cutting device. The system may include a controller and computer enabled instructions to accomplish the above.

摘要： The invention provides a physiological parameter sensing system (50) and method in which physiological information indicative of at least one physiological parameter is derived. The approach of the invention is based on constructing multiple pulse signals from different weighted combinations of at least two detection signals, derived from detected electromagnetic radiation directed onto or through a subject's skin region. The weightings are based on different of a set of various blood volume pulse vectors. A quality indication value is derived for each generated pulse signal, where this is based on a derived relationship between an obtained heart rate signal for the patient and the pulse signal. The blood volume pulse vector resulting in the pulse signal having the highest quality indicator value and/or from the derived pulse signal itself is used to derive the physiological parameter information.

摘要： A biosensor identifies a blood type using photoplethysmography (PPG) technology. A PPG circuit obtains a plurality of spectral responses at a plurality of wavelengths detected from skin of a user. A processing circuit determines a blood factor indicator using the plurality of spectral responses. The blood factor indicator may include a signal quality parameter or a ratio R value. A calibration database includes a correlation of the blood factor indicator to a plurality of blood types. The blood blood type of the user is identified using the blood factor indicator and the calibration database.

摘要： Some methods may involve receiving, at a first node of the health network, encrypted sensor data from one or more sensors. The first node may be in a data communication path between the one or more sensors and other nodes of the health network. The method may involve decrypting, by the first node of the health network, only a portion of the encrypted sensor data, and transmitting the encrypted sensor data from the first node of the health network to a second node of the health network. The first node may be a gateway device. In some examples, the second node may be able to decrypt more of the encrypted sensor data than the first node.
