An apparatus for fluid detection comprises a fluid sensor positioned near a patient's body, an alarm connected to the fluid sensor, a closeable casing having a size that allows it to maintain the alarm within a space that is defined by the closeable casing, and a fastener coupled to the closeable casing. The fluid sensor provides a signal whenever the fluid sensor detects fluid. The alarm includes one or more status indicators that are responsive to the signal. The closeable casing allows the patient to see, hear, or otherwise sense, the alarm through the closeable casing. The fastener is affixed to: the patient's body, the patient's clothing, or both. The casing can be opened and closed, and optionally, the alarm can be removed and replaced in the space the casing defines.

An agent activated non-metal antenna for an ultra-high frequency (UHF) wireless sensor having a radio frequency identification (RFID) tag in electronic communication with the non-metal antenna, and a wireless data communication integrated circuit (IC), includes a conductive stimuli-responsive hydrogel material configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent. The antenna is further configured to transmit power to turn on the wireless data communication IC only when the non-metal antenna is active upon interaction with the activating agent.

An incontinence detection system includes an incontinence detection pad for placement beneath a person to be monitored. The incontinence detection pad has a passive radio frequency identification (RFID) tag. A reader is provided and a plurality of antennae is coupled to the reader. The reader includes a bistatic radio frequency (RF) switch matrix which is operable to establish a first antenna of the plurality of antennae as a transmit antenna that is used to wirelessly energize the passive RFID tag and to establish a second antennae of the plurality of antennae as a receive antenna that is used to read backscattered data that may be emitted from the passive RFID tag. The first and second antennae are situated in respective housings that are spaced apart from each other. An arrangement of first and second electrodes on an electrical sheet of an incontinence pad is also provided.

The present invention provides a nocturnal enuresis treatment device 1 including a sensor 10 for detecting urination; one or more stimulation pads 20 constituted to impart a stimulus to a wearer; and a mechanical portion 30 including the following: (i) a stimulus generation unit 31 for generating a signal for causing the stimulation pads 20 to impart the stimulus to the wearer, and (ii) a control unit 32 for generating a signal for causing the stimulus generation unit 31 to generate the stimulus in response to urination detection by the sensor.

A notification device is provided that includes a sensor pad, and an electronics module generates one or more notifications in response to signals received from the sensor pad. In a first embodiment, the sensor pad includes a pressure sensor for sensing pressure applied by a patient and generating a pressure signal, and conductive tracings for sensing moisture due to incontinence and generating a moisture detection signal when moisture is detected. In another embodiment, an absorbent sensor pad includes a sensor pad for sensing moisture and includes an absorbent chuck having a moisture-impermeable sheet with an absorbent material on an upper surface thereof, wherein the moisture-impermeable sheet has an aperture for receiving the sensor pad. The absorbent sensor pad may be provided in the form of a diaper.

A device for detecting moisture for an arrangement for monitoring an access to a patient for a system by which, via a flexible line, a liquid is fed to a patient and/or a liquid is fed out from the patient, and in particular for monitoring the vascular access in extra-corporeal blood treatment and particularly for monitoring a central venous catheter for acute dialysis includes at least a portion which can be deformed into a sleeve and placed around the circumference of the flexible line or of a connecting system. The portion in sleeve form has fastening means for fixing it in place in the position in which it surrounds the flexible line or the connecting system. The portion in sleeve form allows the device to be fastened quickly and securely to a flexible line or a connecting system.

A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.

There is disclosed herein a sensor for detecting at least one of urination and excretion into an incontinence garment, the sensor comprising an activation unit and a sensing unit and being connectable to a power supply; the activation unit comprising: two spaced-apart electrodes, and a switch arranged in series between the sensing unit and the power supply; wherein the activation unit is configured to activate the sensing unit in the presence of moisture by closing the switch; and wherein at least one of the sensing unit and the activation unit comprises a latching circuit arranged such that the activation of the sensing unit is irreversible. An incontinence garments such as the diaper is incorporating such a sensor is also disclosed as it is a method for operating such a sensor or incontinence garment.

A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.

A room monitoring device designed and intended to detect a bowel movement (BM) of a person occupying the room, such as a baby or infant or an adult with special needs or in a care facility. The device tests the air for particular substances such as, but not limited to, methane and hydrogen sulfide. The test is performed multiple times per minute to reduce the chances of a false-positive detection. Once the device detects a positive BM, it alerts a user via Wi-Fi message, SMS text message, visual alerts (e.g., flashing lights), and/or audio alerts. This device may be paired with existing monitoring devices, such as a baby monitor with a remote camera.
