Definitions

  • the present invention concerns a pressure equalizing device comprising a fluid container, i.e. liquid and/or gas container, for attachment to a receptacle, such as a vial, to permit pressure equalization between the fluid container and the receptacle.
  • a fluid container i.e. liquid and/or gas container
  • a receptacle such as a vial
  • the present invention also concerns a receptacle comprising such a pressure equalizing device.
  • Some drugs must be dissolved or diluted before they are administered, which involves transferring a solvent from one container to a sealed vial containing the drug in powder or liquid form, by means of a needle for example. Drugs may be inadvertently released into the atmosphere in gas form or by way of aerosolization, during the withdrawal of the needle from the vial and while the needle is inside the vial if any pressure differential between the interior of the vial and surrounding atmosphere exists.
  • the pressure equalization device comprises a gas container in communication with the interior of the vial, which ensures that neither an increased pressure nor a vacuum can occur inside the vial when gas or liquid is injected into or withdrawn from the vial.
  • the gas container may be filled with cleaned or sterilized air prior to its use to ensure that the contents of the vial do not become contaminated with air-borne particles such as dust, pollen, mould or bacteria and other undesirable substances.
  • US 2007/106244 describes a vial adapter 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.
  • An object of the present invention is to provide an improved pressure equalizing device comprising a fluid container, i.e. gas and/or liquid container, for attachment to a receptacle, such as a vial, to permit pressure equalization between the fluid container and the receptacle.
  • a pressure equalizing device comprising the features of claim 1, which comprises a fluid container and 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.
  • the pressure equalizing device also comprises 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.
  • the pressure equalizing device equalizes pressure in the fluid container and the receptacle by allowing filtered fluid to flow into or out of the receptacle depending on whether the pressure is temporarily greater in the fluid container or the receptacle.
  • the pressure equalizing device thereby provides a simple, closed system that allows for safe and reliable injection or withdrawal of substances, such as toxic drugs, into or out of a receptacle while at least minimizing, or eliminating the risk of the substances contaminating breathable air.
  • the filter-receiving means comprises a removable or non-removable filter.
  • a filter with the mesh size 0.2 ⁇ m may be used to remove substantially all particles and micro organisms of that size or larger.
  • the filter may be a sterilizing or aseptisizing filter, such as a particulate air filter, such as a high efficiency particulate air (HEPA) filter to remove gas-borne particles such as dust, pollen, mould or bacteria and thus eliminating or at least reducing the risk of such gas-borne particles from contaminating substances inside the vial.
  • HEPA high efficiency particulate air
  • the pressure equalizing device may comprise a plurality of filters of the same type or of different types.
  • the filter-receiving means are located upstream or downstream of the one-way valve in the fluid inlet, which permits fluid to be filtered as it flows into the fluid container when the filter-receiving means comprises a filter.
  • the filter-receiving means are located in the flow channel, which permits fluid to be filtered as it flows out of the fluid container into the receptacle when the filter-receiving means comprises a filter.
  • the fluid container is an air container.
  • the fluid inlet is arranged to be in communication with ambient, i.e. non-sterilized air. Since ambient air can be cleaned on site using a sterilizing or ascepticizing filter in the pressure equalizing device, neither a sterile environment, nor extra equipment, nor a supply of clean air is necessary to fill the fluid container with cleaned air.
  • the pressure equalizing device according to the present invention may therefore be filled or replenished with cleaned fluid almost anywhere, in a simple manner and at low cost.
  • the fluid container comprises a flexible portion, such as a bladder, i.e. a portion comprising a flexible or expandable material, whereby the volume of said portion can be increased by drawing fluid into the fluid container and decreased by withdrawing fluid from the fluid container.
  • the fluid container may however be at least partly constituted of a rigid, non-compressible material.
  • the one-way valve is integrally formed with the filter-receiving means or a filter.
  • the filter-receiving means is removable from the fluid container.

  • the flow channel 18 of the pressure equalizing device permits gas to flow from the interior of the vial 12 into the gas container 16 or from the gas container 16 to the vial 12, and thereby equalizes the pressure in the interior of the vial 12 and in the gas container 16. Gas may enter the gas container 16 via the fluid inlet 20, however gas cannot exit the gas container 16.
  • FIG 3 shows the rigid, incompressible part 16a of the gas container 16 shown in figures 1 and 2 .
  • This part 16a of the gas container comprises the gas inlet 20 that contains a one-way valve 28 that permits gas to flow into the gas container 16 via the gas inlet 20 and that prevents gas from flowing out of the gas container 16 via the gas inlet 20.
  • the gas inlet 20 also comprises filter-receiving means 30 that are located upstream of the one-way valve 28.
  • the gas inlet 20 is arranged to be in communication with ambient air. When a filter is placed in the filter-receiving means 30 ambient air is filtered as it flows into the gas container 16.
