  • Patent number: 10420882
    Abstract: Method and system for controllably administering and/or withdrawing fluid from a patient. In one embodiment, the system may include a needle assembly, an ultrasound imager, a fluid supply storage unit, a waste storage unit, a fluid pump, and a foot pedal assembly. A syringe may serve as the fluid supply storage unit and the waste storage unit. The pump may include a bi-directional motor and a gear coupled to the motor. The gear may be engageable with a rack on the syringe plunger to drive the plunger either for fluid aspiration or infusion. Depression of one portion of the foot pedal assembly causes the motor to drive the gear in one direction, and depression of another portion of the foot pedal assembly causes the motor to drive the gear the other direction. The system may include a control device to keep pressure in the fluid path from exceeding a limit.

  • Patent number: 6709599
    Abstract: A method and apparatus for processing waste streams wherein a slipstream is formed on the upstream side of an ultrafiltration membrane (120) to carry collected and concentrated filter reject to a microfilter (170) via a slipstream through a conduit (155) at a very low flux through the microfilter. The low flux gives the particles in this stream a chance to interact and thus form an irregular matrix that itself helps to trap particles. The effluent from this matrix and microfilter is returned upstream of the ultrafiltration membrane via a conduit (165) to be repeatedly collected and concentrated. The suspended solids removed from the reject stream and microfilter may then be disposed of directly without further processing. For metal ions, the removal efficiency of ultrafiltration membrane can be improved by injecting sulfide compounds or other compounds upstream of ultrafiltration membrane.

  • Publication number: 20020122525
    Abstract: A system and method for removing and collecting particulate from a water-filled tank using a filter and a pump wherein the pump operates at low flow rate to maintain only a small pressure drop across the filter low. By maintaining a small pressure drop, particulate agglomeates and can load the filter to a greater extent than when the flow rate is higher. The filter may then be crushed and placed into a disposal container for disposal. In an alternate embodiment, the particles can be accumulated in several mesh filters operating at a higher flow rate and then, as each filter is loaded, the filtrate can be back flushed to a second filter operating at low flow rate. The first filters can be repeatedly reused and the second filters can be crushed and placed in a disposal container.

  • Patent number: 5533991
    Abstract: A bodyside cover for an absorbent article is disclosed which includes two different materials to provide enhanced functionality. The bicomponent cover includes an apertured first material, which is positioned along the longitudinal central axis of the absorbent article, and a nonperforated second material secured to at least a portion of the first material. The first material has a rewet value which is less than, or equal to, the rewet value of the second material while the second material is softer than the first material. The first material is positioned below the principal point of fluid discharge and represents the primary fluid-receiving region of the cover. The second material is situated away from the principal point of fluid discharge and represents the secondary fluid-receiving region of the cover.

  • Patent number: 5188625
    Abstract: A sanitary napkin is disclosed which has an absorbent and a fluid-permeable cover positioned over at least one surface of the absorbent. The cover is formed from a nonwoven web having a network of essentially unbroken thermoplastic fibers. The web has a plurality of apertures formed therethrough which are located in a predetermined area which represents less than about 80% of the surface area of the cover. Each of the apertures is surrounded by a consolidated ring formed of thermally set thermoplastic fibers which in turn is surrounded by a raised area which contacts the body of the user. The apertures formed in the web occupy about 20% to 55% of the predetermined area and permit body fluid to quickly pass through to the absorbent.

  • Patent number: 4886632
    Abstract: A method of perforating a nonwoven web of fibrous fabric by directing the web through a nip defined by first and second moveable members. As the web moves through the nip it is penetrated by a plurality of heated pins projecting from the first member which enter heated apertures formed in the second member. The penetration of the pins causes the fibers of the fabric to separate and enter into the apertures and form openings through the web. The openings are surrounded by dense consolidated rings exhibiting greater hydrophilic properties than the nonperforated surface of the web.

  • Patent number: 4315507
    Abstract: A sanitary device, e.g. a sanitary napkin is provided which has an absorbent matrix and a fluid impervious baffle. Part of the fluid impervious baffle is a heat fusible sheet which is adhered to the absorbent component by fusing. The absorbent component may have heat fusible material interspersed therein and may have a fluid pervious upper layer which is essentially coterminous with or wraps about the absorbent component or the absorbent component and baffle combination. When a fluid pervious wrap is used, it is preferred that the wrap be fusible and also be fused to the baffle. The fusing is preferably accomplished in random sites across the surface of the sanitary appliance, e.g. by embossing.
