Abstract:
A dry mouth test is provided comprising placing a wickable test strip in the mouth of a subject to collect salivary fluid. Distance migrated by the saliva over a specific period of time correlates with the production of saliva and dryness of the mouth. A marker dye is optionally used on the strip which co-migrates with the saliva front and aids in indicating the distance saliva migrates on the strip. A graduated migration scale is printed on the strip to indicate the distance traveled by the saliva. Saliva production is measured with or without stimulation of the salivary glands.
Abstract:
Изобретение относится к области медицины. Способ прогнозирования времени критического развития ВИЧ- инфекции после родов заключается в том, что у беременных ВИЧ-инфицированных женщин на 12-ой неделе беременности до начала терапии, индуцирующей иммунологический контроль ВИЧ, измеряют показатель вирусной нагрузки и устанавливают возраст и длительность заболевания женщины, которые определяют числом полных лет плюс числом полных месяцев, деленным на двенадцать. На 30-ой неделе беременности на фоне указанной терапии измеряют количество CD4 + -T - лимфоцитов и определяют показатель времени критического развития ВИЧ-инфекции после родов по формуле. Устройство для прогнозирования содержит основание в виде диска с нанесенными на него двумя концентрическими шкалами, одна из которых соответствует результирующим показателям, а другая - одному из факторов, влияющих на эти показатели. При этом соосно основанию с возможностью вращения установлены четыре диска меньшего диаметра, на которых нанесены шкалы других факторов, влияющих на результирующие показатели. Диаметр каждого последующего диска меньше диаметра предыдущего диска. На каждом из дисков образован указатель в виде выступа. Диск самого меньшего диаметра не имеет шкалы и снабжен двумя указателями, один из которых имеет с длину, достаточную для взаимодействия со шкалой результирующих показателей.
Abstract:
A disposable, wearable article can be used for collecting a sample and performing urinalysis. The article incorporates a test port feature to simplify this function. The test port has a resealable cover that can be used to selectively expose an aperture through the backsheet of the disposable article. The test port is used to position test devices, such as urine test strips to urine collected in the disposable article.
Abstract:
The present invention is directed to devices and related methods for indicating the presence of a target analyte in a bodily secretion located on the skin of a subject. The target analyte is preferably an illicit drug or metabolite thereof.
Abstract:
A urinary directional device for improving the directional urination and health of a male user is provided, in which the device comprises a conduit (1) for the passage of urine and having a proximal end (3) adapted for engagement with the penis of the user and a distal end (5) having a distal aperture to enable the passage of urine from the conduit, the device having an interior surface providing one or more of a cleansing, an anti-bacterial or antiseptic or an anti-fungal function whereby the penis of the user can be cleansed by wiping on the interior surface of the device after urination and the device further comprising a health detection indicator capable of indicating abnormalities in urine indicative of disease or health-related conditions.
Abstract:
Disclosed are systems and methods for urinalysis. Many of the systems and methods disclosed herein are adaptable for use with a normal toilet, such as a standard "seat" toilet, which can be readily obtained commercially. In certain embodiments, the present invention is directed to uninalysis devices that are able to receive urine and determine analytes within the urine, for example, using a sensor such as an ion-selective electrode sensor. For instance, such a device mounted to a toilet may include a urine receiver and a fluid chamber containing a sensor. In some cases, the device may also include a reservoir for passing buffer or other liquids through the fluid chamber, e.g., for cleaning purposes. The urine receiver, in some cases, may be movable (e.g., into the middle of the toilet) in order to receive urine, then moved onto the side afterwards. The sensor, in turn, may be connected to electrical equipment for analysis of the urine, storage of the data, communication of the data (e.g., to the subject, and/or to a doctor or health care provider), or the like.
Abstract:
Methods and devices for the non-invasive collection of a liquid sample in small quantities, such as urine for testing hydration in infants and incontinent adults, directly at the source of that sample, isolation of the collected sample from a testing site, the transportation of that sample to a site for testing contained within the device itself, and the selective application of some or all of the specimen to a testing apparatus contained within the device itself, with a minimum of specimen handling required. Other aspects include a method and device for facilitating the reading of the result of the specimen test by a skilled or unskilled user, including means for determining that no adequate sample has been delivered to the testing site.
Abstract:
The present invention is directed to headwear including a cooling device formed using a woven or non-woven material. More particularly, the invention relates to headwear including a cooling device formed of an absorptive material such as polyvinyl alcohol (PVA) having high absorptive capacity. The headwear and the cooling device are designed to fit securely on the wearer's head or with a hat. When moistened, the cooling device provides sustained cooling via an evaporative cooling process.
Abstract:
The present invention is a system and a method for blood or urine sampling and sample-analysis, through a sampler that is a self blood-testing device or a urine-testing device. The system comprises a sampler, a transmission unit and an analysis unit. A patient may place a sampled blood drops on a sample strip and insert the strip into the sampler. The sampler may automatically prepare the sample and photograph it using a sample-preparation unit and a photography unit respectively. After the sample has been photographed, the resulting sample image may be transmitted to the analysis unit that may analyze the image through an image-processing algorithm. The analysis results may be automatically transmitted to the patient and to a medical authority, such as the patient's physician, a nurse, a clinic and the like, for further analysis, decision-making and treatment.
Abstract:
An integrated lancing test strip device includes a lancet configured to form an incision in tissue and a test strip coupled to the lancet for analyzing body fluid. A retention mechanism acts as a detent to hold the lancet in a static position relative to the test strip before forming the incision. The retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip to reduce smearing of body fluid by the lancet during collection of the fluid with the test strip. In one form, the retention mechanism includes breakable tabs that are broken to release the lancet, and the lancet is retracted via translational movement. The retention mechanism in another form includes one or more dimples that release the lancet when the lancet is retracted via rotational motion. In a further form, the entire integrated device is rotated to collect fluid.
