A distal shaft for measuring pressure distally of a stenosis includes a housing, a pressure sensor, a cover, a tip, and an aperture. The pressure sensor is mounted in the housing. The cover is coupled to the housing and covers the pressure sensor. The tip is coupled to a distal end of the housing. The aperture is disposed through the tip and/or cover. The aperture is configured to allow blood flow to the pressure sensor. The cover further includes a coupling mechanism or coupling that couples the cover to the housing. The coupling mechanism may be a snap-fit mechanism, a friction-fit mechanism, and/or an adhesive.

An apparatus for generating ECG recordings and a method for using the same are disclosed. The apparatus includes a handheld device having four electrodes on an outer surface thereof, the handheld device having an extended configuration and a storage configuration. The apparatus also includes a controller configured to measure signals between the electrodes to provide signals that are used to generate an ECG recording selected from the group consisting of standard lead traces and precordial traces. When the handheld device is in the extended configuration and the first and second electrodes contact a first hand of a patient such that the first and second electrodes contact different locations on the first hand, the third electrode is in contact with a location on the patient's other hand and the fourth electrode contacts a point on the patient's body that depends on the particular trace being measured.

Systems, devices, and methods for determining anosmia and/or ageusia in a subject. are provided. Devices may include a housing, a composition stored within the housing, and an applicator. The composition may include one or more active ingredients and one or more inactive ingredients, the one or more active ingredients including a flavoring agent that may include salt, sour, sweet, or bitter taste and odor properties. The composition may be configured to remain stable. The housing may include a back pressure mechanism. The applicator may be configured to remove a predetermined amount of the composition from the housing and deliver the predetermined amount of the composition to one or more of a nose and a mouth of the subject.

A system for capturing information related to an aspect associated with an aerosol-generating device is provided, the aspect comprising at least one of a user aspect and a consumable aspect, the system including: a signal capture system including one or more acoustic actuators configured to generate an acoustic signal and including a button, and an acoustic sensor, the one or more acoustic actuators and the acoustic sensor being located at predetermined locations with respect to the aerosol-generating device such that an acoustic signal generated by pressing the button is modulated at least in part according to the aspect before being detected by the acoustic sensor, thereby capturing the information related to the aspect.

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.

A method for preventing infection by a virus includes obtaining a sample from a person, assaying the sample to determine whether the person has been previously infected with a predetermined virus, and if the person has not been previously infected with the virus, providing the person with a sensor positioned to detect when a person's hand approaches a predetermined distance from the person's face. By warning the person of undesired hand-to-face contacts, the person is able to reduce the incidence of related viral infections.

A light attachment device for removable attachment to an electrosurgical pencil and/or an electrosurgical pencil attachment such as a shroud for an electrosurgical pencil. The light attachment device may be automatically turned on and off in conjunction with the activation and deactivation of the electrosurgical pencil and/or electrosurgical pencil attachment.

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 optical sensing device is provided for receiving and transmitting a light signal. A light working area is defined according to a measurement range of the light signal. The optical sensing device includes a body, a transformation part and a signal unit. A light emitting unit and a light receiving unit are disposed at an end of the body, and the light emitting unit and the light receiving unit face the light working area. The transformation part pivots on the body. A light processing unit is disposed on the transformation part, and the light processing unit is capable of locating in the light working area for transmitting or receiving the light signal. The signal unit is configured for transmitting and processing the light signal.

A combined intraocular pressure (IOP) measuring and eye medication dispensing device may include a first micro-electro-mechanical-system (MEMS) sensor to generate IOP measurements of a living organism's eye; a medication dispensing device to dispense medication into the living organism's eye; a second MEMS micro-dispenser to interface with the medication dispensing device and to control the dispensing of the medication into the living organism's eye; and an analog-to-digital (A-to-D) converter to receive control signals. The A-to-D converter may communicate the control signals to the first MEMS sensor or the second MEMS micro-dispenser; receive the generated IOP measurements from the first MEMS sensor; receive medication dispensing parameters from the second MEMS micro-dispenser or medication dispensing device, and communicate the generated IOP measurements or the medication dispensing parameters. The device may also include a communications interface to receive the control signals from one or more processors in an external control module.
