  • Patent number: 9080681
    Abstract: A device is placed upon a container that is sealed by a sealing element and filled with a liquid, the device allowing the liquid to be withdrawn. The device is provided with a penetration element with a hollow needle that is held in an unused position on a head section. The penetration element is held by guide elements on the head section so that the element can be pressed against the sealing element in a withdrawal position, in which the hollow needle penetrates the sealing element. At least one aeration channel is provided to equalize the pressure in the container during the withdrawal of the liquid, the channel running preferably along the hollow needle. The air sucked from the atmosphere enters the aeration channel via a filter. This prevents the contamination of the liquid and the latter can be withdrawn without the risk of a reverse flow.

  • Patent number: 8029747
    Abstract: Pressure equalizing device comprising a fluid container for attachment to a receptacle such as a vial to permit pressure equalization between the fluid container and the receptacle. The pressure equalizing device comprises a flow channel that is arranged to provide fluid communication into or out of the fluid container when the pressure equalizing device is attached to the receptacle. The pressure equalizing device also comprises a fluid inlet that contains a one-way valve that permits fluid to flow into the fluid container via said fluid inlet and that prevents fluid from flowing out of the fluid container via said fluid inlet and filter-receiving means that are arranged to permit fluid flowing into or out of the fluid container to be filtered when the filter-receiving means comprises a filter.

  • Patent number: 7993531
    Abstract: Biological fluid filtration methods are provided for the treatment of gas within a biological fluid filtration system. A quantity of biological fluid is flowed under the force of gravity through a leukocyte removal filter and into a post-filter container. The post-filter container has a maximum vented volume that is approximately the same as the quantity of biological fluid flowed through the filter and into the post-filter container. At least a substantial portion of the gas in the post-filter container is vented therefrom without separately restricting expansion of the post-filter container and without manually manipulating the post-filter container to expel gas.

  • Patent number: 7938967
    Abstract: A vent assembly is described for use in an extracorporeal fluid unit. A vent structure adjacent to a micro-porous membrane forms the assembly. The vent structure is porous, but expands when the vent structure becomes wet, thereby closing off the pores and inhibiting (e.g., preventing) fluid from flowing through the vent structure. The vent structure also protects the membrane from becoming wet, such as from condensation.

  • Patent number: 7867214
    Abstract: In a peritoneal dialysis embodiment of the present invention, spent dialysate from the patient's peritoneal cavity passes, along a patient loop, through a dialyzer having a membrane that separates waste components from the spent dialysate, wherein the patient loop returns fresh dialysate to the patient's peritoneal cavity. The waste components are carried away in a second regeneration loop to a regeneration unit or sorbent cartridge, which absorbs the waste components. The regeneration unit removes undesirable components in the dialysate that were removed from the patient loop by the dialyzer, for example, excess water (ultrafiltrate or UF), toxins and metabolic wastes. Desirable components can be added to the dialysate by the system, such as glucose and electrolytes. The additives assist in maintaining the proper osmotic gradients in the patient to perform dialysis and provide the necessary compounds to the patient.

  • Patent number: 7762976
    Abstract: An apparatus for extracorporeal oxygenation of a patient's blood during cardiopulmonary bypass surgery. The apparatus comprises a bubble sensor, arranged at or connected to a venous line, for detecting bubbles in the venous blood received from the patient. When air bubbles are detected, a second pump is activated to draw air from an air chamber provided in an air filter connected to the venous line and arranged downstream of the bubble sensor. A first pump draws the blood from the air filter and supplies the blood to an oxygenator and to the patient via an arterial line.

  • Patent number: 7743799
    Abstract: A vial adapter is described comprising a housing, the housing comprising an expandable chamber to contain a volume, an internal passage in communication with the expandable chamber, at least one opening in communication with the internal passage, and an access member integral with the housing. A hollow spike comprising a proximal end is integral with the housing and a distal end. The spike comprises a vent lumen open at the distal end and a fluid lumen open at the distal end, the vent lumen is in communication with the internal passage and the fluid lumen is in communication with the access member. A first check valve restricts communication from the expandable chamber to the internal passage, and a second check valve restricts communication from the internal passage to the opening. Methods of reconstituting and/or withdrawing hazardous material using the vial adapter are described.

  • Publication number: 20090270831
    Abstract: The present device is a suppression device for containing sound and germs emanating from a user's cough. A substantially hollow tube forms a gas conduit with a gas-permeable end membrane fixed within the tube across the gas conduit. A layer of a gas-permeable anti-bacterial material is fixed within the tube against the end membrane and a gas-permeable filter material is fixed within the tube against the anti-bacterial material. When a user needs to cough, the user coughs into the suppression device whereby the emanating germs and sound are suppressed as they encounter the filter material, the anti-bacterial material, and the end membrane. The suppression device further includes a lanyard permitting a user to wear the device and a label to write the user's name on the device. The suppression device is primarily comprised of biodegradable materials, allowing the suppression device to be disposable in an environmentally friendly way.

    Abstract: In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a piercing member and a bag. The bag can be contained within the piercing member such that the bag is introduced to the vial when the vial adaptor is coupled with the vial. In some embodiments, the bag expands within the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. In other embodiments, a vial comprises a bag for regulating pressure within the vial as liquid is removed therefrom. In some embodiments, a vial adaptor is coupled with the vial in order to remove the liquid. In some embodiments, as the liquid is removed from the vial via the adaptor, the bag expands within the vial, and in other embodiments, the bag contracts within the vial.
