An elongated device and a system that at the same time allow acquisition of temperature-related data of high spatial and temporal resolution from hollow structures together with other relevant data of physical or chemical variables. In a preferred embodiment infrared or visible light sensors are used to obtain thermal or color images from the inner surface during imposed change of the temperature in the lumen of the hollow structure. The disclosure makes it possible to evaluate thermal variations when the inner surface returns to pre-change thermal conditions. High-resolution data can be obtained with the disclosure. The disclosure further includes a system with rotators, injection pumps, a control unit and display operably coupled to one or more of the data acquisition and processing system.

The present disclosure relates to a patch-type thermometer using a thermochromic ink, and particularly to, a patch-type thermometer capable of accurately measuring a body temperature even in special environments.

Apparel for monitoring optimal body shell temperature during physical activity. The apparel uses thermochromic dyes and thermochromic inks to indicate changes in body shell temperature as physical activity commences and progresses. The thermochromic dyes and inks reveal when the body shell temperature has reached a temperature indicating optimal muscle performance, and inform the wearer of the apparel whether to increase or decrease the intensity of the physical activity to establish or maintain the optimal body shell temperature.

The invention provides head, neck, chest, and spine logical impact protection and thermal-regulation device having a webbing adapted to encapsulate head and neck, wherein the webbing is composed of a plurality of reversibly deformable substrates that are capable of being cooled or heated; wherein the webbing further provides apertures interspersed between the reversibly deformable substrates to allow fluid exchange between the head, neck, chest, and spine and the regions exterior to the webbing; and a temperature indicator, wherein the temperature indicator measures the temperatures of the body surface underlaying the webbing.

A wearable indicator device includes: a flexible sheet having a first surface with an adhesive covering at least a portion of the first surface and a second surface configured to be positioned proximate to skin of a wearer of the wearable indicator device; and a visual temperature indicator. The visual temperature indicator is configured to be visible to bystander(s) when the wearable indicator device is being worn and changes in appearance when exposed to a temperature corresponding to a temperature exceeding a normal body temperature of the wearer to provide a visual indication when the wearer has an abnormal body temperature. The visual temperature indicator is connected to, embedded in, or integral with the flexible sheet, such that the flexible sheet is configured to hold the visual temperature indicator proximate to the skin of the wearer.

A contact thermography kit comprising a plurality of temperature sensitive thermographic plates arranged to be placed in contact with the skin of a user, where each plate is adapted to assume a graphic pattern as a function of a detected temperature interval, so as to generate a corresponding thermographic image, and the plurality of plates is adapted to measure temperatures between 24° and 36°.

Apparatuses including features for predicting pressure wound formation are disclosed. A wheelchair apparatus includes a seat having a surface that contacts a subject when the subject is sitting in the wheelchair apparatus. The surface includes a thermochromic layer having one or more materials that cause the thermochromic layer to change to a first color upon application of thermal energy radiating from the subject that corresponds to a baseline body temperature and change to a second color that is different from the first color upon application of thermal energy radiating from the subject that corresponds to a temperature that exceeds a threshold difference from the baseline body temperature. The second color is indicative of a potential pressure wound.

A method of monitoring a patient's foot forms a thermogram of the sole of at least one foot of the patient, and determines whether the thermogram presents at least one of a plurality of prescribed patterns. The method also compares the thermogram against a prior thermogram of the same foot, and produces output information indicating the emergence of an ulcer on a given portion on the at least one foot as a function of 1) whether the thermogram is determined to present the at least one pattern, and 2) the comparison with the prior thermogram, which shows non-ulcerated tissue at the given location.

The thermochromic dyes and inks reveal when the body shell temperature has reached a temperature indicating optimal muscle performance, and inform the wearer of the apparel whether to increase or decrease the intensity of the physical activity to establish or maintain the optimal body shell temperature.

A combined apparatus for indicating the elevated temperature of an infant and for sensing moisture in a diaper. The combined apparatus includes an elongated sensing strip made of highly efficient liquid absorption and transfer capillary wick material having a first end disposed in engagement with the diaper. The elongated sensing strip has a first side having a pair of screen-printed, spaced apart conductive ink bands which couple electrically at one end with a portable alarm unit and a second side having an elongated band of thermochromic ink printed thereon a segment of which is visible proximate the second end of the elongated sensing strip.
