A wireless near-infrared spectrometry sensor includes a light source for emitting near-infrared energy into tissue and a light receiver for receiving the near-infrared energy after it exits the tissue. The sensor may include a portable energy source for supplying energy to the light source. A processing module may control the light source and process readings in connection with the light source. A wireless transceiver may be coupled to the processing module for at least one of transmitting and receiving information, wherein the light source emits near-infrared energy at predetermined intervals in order to conserve energy in the portable energy source. The portable energy source may include at least one of a battery, a capacitor, a thermoelectric generator, a kinetic energy transducer, electricity derived from RF energy, and any combination thereof. The sensor may further include a substrate for support and which may be part of a sterile bandage.

A method and system for continually monitoring oxygenation levels in real-time in compartments of an animal limb, such as in a human leg or a human thigh or a forearm, can be used to assist in the diagnosis of a compartment syndrome. The method and system can include one or more near infrared compartment sensors in which each sensor can be provided with a compartment alignment mechanism and a central scan depth marker so that each sensor may be precisely positioned over a compartment of a living organism. The method and system may comprise hardware or software (or both) may adjust one or more algorithms based on whether tissue being monitored was traumatized or is healthy. The method and system can also monitor the relationship between blood pressure and oxygenation levels and activate alarms based on predetermined conditions relating to the oxygenation levels or blood pressure or both.

A monitoring system for monitoring a kidney-related condition of a living creature. The monitoring system comprises an implantable sensor for repetitively measuring creatinine information in bodily tissue or bodily fluids of the living creature and for storing said creatinine information, and a processor programmed for determining, from the stored information, a kidney-related parameter for the living creature.

The embodiment of the invention discloses a medical fluorescence imaging data acquisition system and an acquisition method thereof and belongs to the technical field of fluorescence imaging. The medical fluorescence imaging data acquisition system according to the invention comprises a shooting management module, a fluorescence characteristic storage module, a fluorescence region query module, a fluorescence data acquisition module and an image detection module, wherein the shooting management module is used for controlling and acquiring image information of fluorescence regions by adjusting a focal length, and the fluorescence characteristic storage module is used for storing comparative fluorescence characteristic information in the image information. When the present invention is used for acquiring fluorescence region images at fluorescence positions, by determining and comprising the fluorescence quantity and area information of each fluorescence region with standard data, the fluorescence image is shot again after a shooting focal length is adjusted, to acquire the clearer fluorescence image and reduce later image screening work.

A system is provided that furnishes expert procedural guidance based upon patient-specific data gained from surgical instruments incorporating sensors on the instrument's working surface, one or more reference sensors placed about the patient, sensors implanted before, during or after the procedure, the patient's personal medical history, and patient status monitoring equipment. Embodiments include a system having a surgical instrument with a sensor for generating a signal indicative of a property of a subject tissue of the patient, which signal is converted into a current dataset and stored. A processor compares the current dataset with other previously stored datasets, and uses the comparison to assess a physical condition of the subject tissue and/or to guide a procedure being performed on the tissue.

Arrangements and methods are provided for obtaining information associated with an anatomical sample. For example, at least one first electro-magnetic radiation can be provided to the anatomical sample so as to generate at least one acoustic wave in the anatomical sample. At least one second electro-magnetic radiation can be produced based on the acoustic wave. At least one portion of at least one second electro-magnetic radiation can be provided so as to determine information associated with at least one portion of the anatomical sample. In addition, the information based on data associated with the second electro-magnetic radiation can be analyzed. The first electro-magnetic radiation may include at least one first magnitude and at least one first frequency. The second electro-magnetic radiation can include at least one second magnitude and at least one second frequency. The data may relate to a first difference between the first and second magnitudes and/or a second difference between the first and second frequencies. The second difference may be approximately between −100 GHz and 100 GHz, excluding zero.

A sensor probe has a sensor unit which is embedded in a sheath member which is suturable. The sheath member allows the sensor unit to be sutured and secured to any tissue even in a wet or moist environment. The sensor probe in accordance with the present invention is particularly useful as an intraoral sensor probe for measuring oxygen saturation of a flap tissue inside the oral cavity.

A method for predicting transplant-free survival of a patient suffering from acute liver failure (ALF) or acute liver injury (ALI), the method including: performing a .sup.13C-methacetin breath test which includes administering .sup.13C labelled methacetin to the patient; measuring exhaled breath to evaluate changes in a .sup.13CO.sub.2 to .sup.12CO.sub.2 ratio for a predetermined time after the administering; calculating a PDR-peak value of the patient; and predicting the patient as having high chances of transplant-free survival if the calculated PDR-peak value is above a threshold value or as having low chances of transplant-free survival if the PDR-peak value is below threshold value.

The present disclosure in some embodiments relates to a non-transitory computer-readable medium storing computer-executable instructions that, when executed, cause a processor to perform operations, including obtaining one or more digitized endomyocardial biopsy (EMB) images from a patient having had a heart transplant; extracting a plurality of histological features from the one or more digitized EMB images; and applying a machine learning predictive model to operate on the plurality of histological features to generate a prediction for the patient. The prediction includes a grade or a clinical trajectory associated with the patient.
