The present invention relates to a pen-type medical fluorescent imaging device comprising: a probe which is elongated in the longitudinal direction and has an image capture unit at one end; a plurality of light source units surrounding the image capture unit; and a control unit for controlling the light source units, wherein the light source units comprise: a first light source for emitting light of a first wavelength range so that a blood vessel is marked by a first fluorescent material; and a second light source for emitting light of a second wavelength range so that a glioma is marked by a second fluorescent material, wherein the first and second light sources are selectively controlled by the control unit.

The present invention generally relates to improved medical devices, systems, and methods. In many embodiments, devices, systems, and methods for locating and treating a target nerve with integrated cold therapy and electrical stimulation systems are provided. For example, nerve stimulation and cryoneurolysis may be delivered concurrently or alternately with the cryo-stimulation device. In some embodiments, the device may be operated by a single operator or clinician. Accordingly, embodiments of the present disclosure may improve nerve targeting during cryoneurolysis procedures. Improvements in nerve localization and targeting may increase treatment accuracy, physician confidence in needle placement during treatment, and clinical efficacy and safety. In turn, such improvements may decrease overall treatment times, the number of repeat treatments, and the re-treatment rate. Further, additional improvements in nerve localization and targeting may reduce the number of needle insertions, applied treatment cycles, and may also reduce the number of cartridge changes.

A method and apparatus can be used in the selection of correctly sized respiratory interfaces. The method includes the use of light beams to project sizing markers onto a patient's face, which enables the size of the patient's facial features to be measured relative to a set of interface sizes. A sizing apparatus can include a light source and beam splitters that will refract and project the light source into a series of beams that can be aligned on a patient's face in order to measure the features of the patient.

An electrosurgical instrument configured for connection to a supply apparatus for operation. The instrument has an end opening at the distal end and supports at least one electrode in the area of the end opening to which an alternating voltage potential can be applied. Directly adjoining the end opening, a liner of the electrosurgical instrument limits a flow chamber inside the liner. With distance to the end opening a flushing channel opens out into the flow chamber via an exit opening and a suction channel opens out into the flow chamber via an inlet opening. A flushing fluid can be introduced in the flow chamber via the flushing channel and can be extracted by suction via the suction channel.

An eyewear device that includes a frame and two arms extending distally from the frame with at least one processor included on the frame or the arms and at least two proximity sensors disposed within the frame or arms in a directional manner. The proximity sensors include an infrared signal receiver to receive an infrared emission. The processors execute an operation to warn a person wearing the eyeglasses by emitting a signal selected from a sound, light or vibration when the proximity sensor detects an infrared emission.

Disclosed herein are portable diagnostic measurement devices for determining at least one analysis parameter of a bodily fluid, in particular for determining an analyte concentration in a bodily fluid as can occur in blood glucose determinations. Also disclosed are analysis systems including the measurement device and at least one disposable test element. The test element can be designed as a carrier strip and can contact a receiving surface of the measurement device at least partially in a flat manner, where the receiving surface is arranged on a narrow side of the housing of the measurement device.

A probe tip of an oximeter device includes first and second printed circuit boards (PCBs) that are coupled to the ends of optical fibers that transmit light between the PCBs and into patient tissue that is to be measured by the oximeter device. The PCBs are oriented at an angle between zero and ninety degrees so that the fibers have a curved shape between the locations at which the fibers are coupled to the first and second PCBs. The angular orientation of the PCBs and curved shape of the fibers allows the fibers to have a longer length than if the fibers were straight and allows for light transmitted through the fibers to have a uniform distribution across a cross-section of the fibers as the light is emitted from the fibers into patient tissue. The uniform distribution of light transmitted into patient tissue allows for reliable oximetry measurements.

A lancing device utilizing tail handle to load and adjust depth, includes a shell, an ejection pin, and a tail handle. The tail handle rotates fit with shell in circumferential direction of lancing device and slides fit with shell in axial direction of lancing device; the tail handle has forward sliding limit relative to shell in axial direction; passive impact surface is arranged corresponding to active impact surface on ejection pin for adjusting puncture depth and loading, and passive impact surface is formed by spiral action surface on tail handle; in use state, rotating tail handle will drive position of impact point on passive impact surface to change in axial direction of lancing device, thereby adjusting lancet tip puncture depth; pulling the tail handle backward will force the passive impact surface to come into contact with the active impact surface, and drive the ejection pin to be loaded and locked.

An apparatus for measuring bio-information may include: a pulse wave sensor comprising at least one pair of light emitters which are disposed apart from each other and a light receiver disposed between the at least one pair of light emitters, and configured to measure a plurality of pulse wave signals from an object by using the light receiver and the at least one pair of light emitters; a force sensor configured to measure a contact force that is applied to the pulse wave sensor by the object; and a processor configured to generate an integrated pulse wave signal by integrating the plurality of pulse wave signals based on the contact force and an area of a contact surface of the pulse wave sensor, and estimate bio-information of the object based on the integrated pulse wave signal.

The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object.
