摘要:
A hot melt wetness indicator composition that includes a water insoluble thermoplastic polymer, anionic surfactant, leuco dye, and a component selected from the group consisting of acid, rosin-based tackifying agent, plasticizer, and combinations thereof, and is homogeneous is disclosed. The hot melt wetness indicator composition exhibits a color change after contact with water.
摘要:
A product for monitoring the condition of the wound comprising a biologically inert matrix which absorbs wound exudate and one or more reagents on or in the matrix for measuring one or more markers comprised within the wound exudate. A change in the one or more reagents caused by the one or more markers comprised within the wound exudate provides a visual indication of an alteration in the condition of the wound. Companion wound dressings, kits and methods are also provided.

A color-appearing ink composition includes a surfactant blend of at least two non- ionic surfactants having hydrophilic-lipophilic balance values greater than 10, or a non-ionic surfactant having a hydrophilic-lipophilic balance value greater than 10 and a charged surfactant. The composition includes one or more water-insoluble leuco dyes, a developer and a desensitizer. The composition may be applied to a substrate to form a sensor.
摘要:
A personal absorbent article (e.g., feminine care pad, sanitary napkin, diaper, incontinence pad etc.) has a color change indicator that employs a synergistic combination an acid component and a basic component for signaling to a user when the absorbent article may foster bacterial growth due to moisture absorption. After a certain period of time, the user can visually inspect the color of the color change indicator to obtain an indication of when it is time to replace or remove the article.

This invention relates to improvements to medical devices such as biosensors containing proteins such as oxidoreductases, for example oxidaseand/or peroxidase enzymes. More generally it relates to novel compositions containing proteins which are stabilised to ionising radiation.
摘要:
The invention describes a color-developing composition that contains at least three major components: (1) a leuco dye or a combination of leuco dyes, (2) an color-developer or a combination of color-developers that can form colored complexes with the leuco dyes, and (3) a desensitizer to temporarily remove the effect of the developer so the leuco dye appears in its colorless form. An optional binder may be included so that the composition may be applied to a substrate as an ink. The ink composition may be applied to synthetic polymeric substrates and other substrates that are incorporated into absorbent articles or personal care products.
摘要:
A system for detection and monitoring of body exudates includes an absorbent article and at least one gas emitting substance incorporated within the absorbent article that can emit a gas after a liquid insult. After an insult, a device incorporating at least one gas sensitive composition can detect the gas and signal that an insult has occurred. The gas may also be detected by a non-contact gas sensor linked to a controller and signaling device which can send visual, auditory, and/or vibratory alerts. The alerts may be perceptible in an area outside the wearer's clothing or at a remote location, such as a watch, radio, computer device and/or smart phone. The system can also determine the fullness of an absorbent article and monitor dry time. The system can be used for interactive toilet training or for caring for an infant, a disabled person, an incontinent youth, or an elderly person.

Aspects of the present disclosure involve absorbent articles having components having printed indicia, and more particularly, web materials having indicia printed with a color palette that exceeds the prior art color palette. Such web materials can be printed during the manufacture of components of absorbent articles. As discussed herein, examples of such printed web materials can be used in the manufacture of printed diaper components, such as for example, backsheets, topsheets, landing zones, fasteners, fastening tabs, ears, absorbent cores, and acquisition layers. The apparatuses and methods discussed herein are also applicable to other types of absorbent articles, such as feminine hygiene products.
摘要:
A wetness sensor for an absorbent article that is formed from an ink is provided. The ink includes a proton-accepting chromogen and a proton-donating agent (or color developer). Prior to use, the ink is generally dry and in a protonated form so that it has a visible color. However, upon contact with bodily fluids {e.g., urine, fecal matter, mucus, menses, vaginal fluid, etc.), water in the fluid can lead to deprotonation of the chromogen, thereby resulting in a shift of the absorption maxima of the chromogen towards either the red {"bathochromic shift") or blue end of the spectrum ("hypsochromic shift"). To increase the rate of the color change during use, the present inventors have discovered that a specific type of proton-donating agent may be employed. More particularly, the proton- donating agent is an aliphatic carboxylic acid that is highly soluble in the bodily fluid (e.g., urine), and therefore results in a color change that is very rapid and may be detected within a relatively short period of time. The extent of the color change is also generally sufficient to provide a "real-time" indication of wetness on the absorbent article.
