  • Patent number: 10507143
    Abstract: Excretion by a diaper wearer in a diaper is predicted by providing in or on the diaper on the wearer an excretion detector capable of detecting excretion by the diaper wearer and a motion sensor capable of detecting movements of the diaper wearer. The sensor continuously detects and at least temporarily records movements of the diaper wearer, and these detected movements are analyzed to determine movement patterns. Then, on detection of excretion by the detector, a movement pattern immediately preceding the detection of excretion is stored or flagged as a critical movement pattern. Thereafter each time movements matching the critical movement pattern are detected, a signal is sent to a user.

The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.

    Abstract: Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

  • Patent number: 8858517
    Abstract: An operating system for a medical device pump has a microprocessor controlling the operation of the pump features in a manner to minimize power consumption and maximize the life of the batteries powering the pump. The microprocessor associated with the medical device pump includes a modulation circuit that operates the pump on an intermittent basis and only when a pressure sensor indicates that the pressure asserted by the pump is at a threshold level. The operation of other sensors are powered only in situations when information from the sensor is needed, while other more essential sensors are operated on an intermittent basis by the modulation circuit. A fill sensor is operated intermittently, while a tilt sensor is only activated when a signal is received from the fill sensor. An optical sensor is only activated when the canister is removed from the pump housing, during which the pump is de-powered.

  • Patent number: 8834434
    Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure or space between it and the surface of a patient by forming, preferably, an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer.
