Ophthalmodynamometer Patents (Class 600/489)
  • Patent number: 11272838
    Abstract: The invention relates to a device and a method, by which the intraocular pressure in a patient's eye is changed by artificially applying a variable stimulation pressure causing, upon reaching specific intraocular pressure values, the presence of characteristic measurement criteria in the retina of the eye, which allow global and local retinal blood pressure values to be derived from the intraocular pressure value. Based on the retinal blood pressure values, which are determined online or preferably offline, local retinal perfusion pressure values (rPP) can be computed and represented in an image of the retina as a pressure mapping image.

  • Patent number: 11033980
    Abstract: A device for material processing by laser radiation, including a source of laser radiation emitting pulsed laser radiation for interaction with the material, optics focusing the pulsed processing laser radiation to a center of interaction in the material, and a scanning unit shifting the positions of the center of interaction within the material. Each processing laser pulse interacting with the material in a zone surrounding the center of interaction assigned to the laser pulse so that material is separated in the zones of interaction. A control unit controls the scanning unit and the source of laser radiation such that a cut surface is produced in the material by sequential arrangement of zones of interaction. The control unit controls the source of laser radiation and the scanning unit such that adjacent centers of interaction are located at a spatial distance a ?10 ?m from each other.

  • Patent number: 10575950
    Abstract: Systems for delivering prosthetic heart valve devices and associated methods are disclosed herein. A delivery system configured in accordance with embodiments of the present technology can include, for example, an elongated catheter body, a delivery capsule carried by the elongated catheter body, and two fluid chambers within the delivery capsule. The delivery capsule can be hydraulically driven between a containment configuration for holding the prosthetic heart valve device and a deployment configuration for at least partially deploying the prosthetic heart valve device. For example, the delivery capsule can be urged towards the deployment configuration when fluid is removed from the first chamber and fluid is delivered into the second chamber, whereas the delivery capsule can be urged towards the containment configuration to resheathe the prosthetic heart valve device when fluid is removed from the second chamber and delivered into the first chamber.

  • Patent number: 9301878
    Abstract: A patient interface for an ophthalmic system can include an attachment module, attachable to the ophthalmic system, and a contact module, configured to accommodate a viscoelastic substance between the patient interface and a procedure eye. The viscoelastic substance can include a fluid, a liquid, a gel, a cream, an artificial tear, a film, an elastic material, or a viscous material. The refractive index of the viscoelastic substance can be within a range of approximately 1.24-1.52 at an operating wavelength of the ophthalmic system. The patient interface can further include input ports, output ports, and a suction system. It can be an integrated design or a multi-piece patient interface. The viscoelastic substance can be provided by injection, on the cornea, at the contact module, or in a space bounded by soft elastic films or membranes, such as in a bag.

  • Patent number: 9078612
    Abstract: Provided are systems and methods for noninvasively assessing intracranial pressure by controllably applanating at least a portion of a subject's ocular globe so as to collapse an intraocular blood vessel and correlating the collapse pressure to intracranial pressure. Also provided are ophthalmic components useful in ophthalmic imaging applications, as well as methods of assessing intracranial pressure that are based, at least in part, on the degree of papilledema, if any, present in the subject.

  • Patent number: 8771196
    Abstract: It is an object to provide a cuff for blood pressure meter wherein a tightening mechanism and a holding mechanism have structures with good mechanical strength to enable the improvement of durability and a size reduction, fittability to an arm is improved to achieve higher accuracy of a blood pressure measurement, and operability can be improved. A cuff for blood pressure meter (1) comprises a tightening mechanism (2) for tightening a flexible cuff (11), and a holding mechanism (3) for holding the tightening position of the tightened flexible cuff (11). The tightening mechanism (2) includes a rack (42) formed in a tightening belt (4), and a pinion gear (22). When the pinion gear (22) is rotated, the rack (42) is moved in a tightening direction. The holding mechanism (3) includes holding holes (43) formed at a plurality of positions in the longitudinal direction of the tightening belt (4), and holding pins (31) which engage into the holding holes (43).

  • Patent number: 8764668
    Abstract: A medical blood pressure transducer that provides an identifier to a monitor that conveys characteristics of the transducer. The monitor can use the information to decide whether to function, or in calibration of the system. The transducer may be part of a disposable blood pressure monitoring system, and may include two transducers closely-spaced to provide two separate but identical outputs. In this way, the transducer may be connected to both a patient monitor and a cardiac output monitor at the same time measurements from a single line can be simultaneously supplied to two separate monitoring devices (for example a patient monitor and a cardiac output monitor). The identifier for the transducer may be circuitry, specifically a resistance/capacitance (RC) combination that possesses a characteristic time constant.

  • Publication number: 20110071408
    Abstract: A method for detecting vascular sclerosis is revealed. Firstly set a cuff on a human hand. Then inflate the cuff and later deflate the cuff. Next measure a pressure of the cuff and generate a pressure sensing signal. Process the pressure sensing signal to generate a processed signal and convert the processed signal. Then calculate a systolic pressure and a diastolic pressure according to the converted processed signal and also obtain a vasodilation constant. Thus a hardening of blood vessels is detected according to the vasodilation constant.

  • Publication number: 20030055346
    Abstract: A diagnostic device having a nose fitting used without connection to a breathing gas supply for obtaining flow data values at ambient pressure. The nose fitting is connected to a pressure or flow sensor that supplies data values to a micro-processor. The detection and measurement of breathing gas flow is made from a tight sealing nose fitting (mask or prongs) configured with a resistive element inserted in the flow stream as breathing gas exits from and enters into the fitting. The nasal fitting is further provided with a port for connection to a flow or pressure transducer. The resistive element causes a pressure difference to occur between the upstream side and the downstream side when air flows through the element. The data values may be stored in computer memory to be analyzed for flow limitations.
