  • Patent number: 11957504
    Abstract: Non-invasive blood pressure (NIBP) systems and methods are disclosed that measure a blood pressure, and in some examples a beat-to-beat blood pressure, of a patient without restricting blood flow. The NIBP systems determine an efficacy of administered cardiopulmonary resuscitation (CPR) to the patient based on the measured blood pressure and are able to optionally output the CPR efficacy or generate user prompts based on the CPR efficacy. Further, the disclosed NIBP systems can generate user instructions to administer further treatment to the patient based on the CPR efficacy.

  • Publication number: 20240099583
    Abstract: An example method is performed by a computing device executing instructions stored in data storage, and includes receiving physiologic monitoring data from a plurality of sensors coupled to a patient, receiving information indicating a measurement of patient motion during the patient care event, determining whether the measurement of patient motion is above a threshold, based on determining whether the measurement of patient motion is above the threshold, generating, for the physiologic monitoring data, a respective quality indicator, analyzing, by the computing device, (i) a combination of the physiologic monitoring data from the plurality of sensors and (ii) the respective quality indicator for the physiologic monitoring data to generate a response dependent upon the combination of the physiologic monitoring data as weighted by the respective quality indicator, and based on analyzing, outputting caregiver feedback by the computing device according to the response.

  • Patent number: 5896695
    Abstract: A device and a related method for entrapping both flying or crawling insects such as mosquitos, fleas and ants and the like and which is effective in attracting such insects to the device when they become mired in a tacky entrapping composition. The device is constructed so that it can be easily stored when not in use. The device comprises a box-like arrangement having two halves which are hingedly connected to one another and which can be opened to form a pair of trays and expose an insect entrapping composition in each tray. A highly reflective foil surrounds a perimeter of each half or tray and which may be provided with a luminescent paint to attract the insects and a highly reflective peripheral flange surrounding each tray acts as a mirror surrounding the luminescent paint thereby further enhancing the attraction. When contacting the entrapping composition, the insects are thereupon mired in the entrapping composition.

  • Patent number: 5819688
    Abstract: A pet animal odor absorbing mat comprising a mat or pad formed of a fibrous material, such as a cellulosic material, and which is integrally incorporated with a zeolite mineral during the manufacture of the mat. The pad or mat is primarily based on the cellulosic or other fibrous material such as for example, wood fiber. The wood fibers are mixed with a binding agent such as an acrylic latex or other animal non-toxic binder, and the zeolite while in somewhat of a semi-viscous and semi-liquid state and then allowed to harden. The mat is highly effective for use as a bottom layer in cat litter boxes to absorb both urine or other wetness and highly effective, in literally entrapping odors, such as those odors arising from pet animals. The mat thereupon simultaneously releases oxygen. This type of mineral has been found to be particularly effective in removing those odors arising both from the animal urine, as well as other animal excreta.

  • Patent number: 5782374
    Abstract: A liner for animal feeders designed to receive dry and moist food and liquid beverage to be consumed by the animal. Most animal feeders usually comprise a tray or dish in the nature of a bowl to receive the dry food or liquid. The liner is sized and shaped to fit over the bowl and has a base wall and an enclosing side wall with an open top. The side wall integrally merges into a rim and a downwardly struck peripheral flange with the latter to engage the exterior surface of the animal feeder sidewall. A plurality of liners are nestable in each other and are capable of being packaged in the nested condition. The liners are formed of a paper type material such as a wax-coated paper. By virtue of this construction, they are made waterproof and also capable of being effectively and easily conformed to the shape and size of the bowl with which they are used.

  • Patent number: 5730083
    Abstract: An improved animal feeder in the nature of a dish or bowl for feeding pets and which includes a pest barrier to preclude crawling pests from infestation of the food or liquid to be ingested by the animal. In one embodiment, the invention includes the use of a moat with liquid as a barrier to preclude traversal of crawling insects and, in another embodiment, the invention includes a cartridge or pad containing an insect barricade. In one embodiment, the barricade may adopt the form of a very tacky composition, which effectively entraps insects which come into contact with the composition. In another embodiment, the barricade may adopt the form of a insect repellant. Preferably, the insect repellant is incorporated directly into the entrapping composition to reduce evaporation thereof, and which also makes the device more effective. The animal feeder essentially includes an upper bowl with a lower level receptacle containing either the moat of liquid or the insect repellant.
