Definitions

  • the present invention relates to a connector device for connecting a first and a second fluid container.
  • the connector device has an improved valve arrangement which permits fluid flow in two different directions.
  • the substance consists of cytotoxic drugs, radio-labelled or allergy-inducing substances it is for safety reasons important that the transfer of such substances from the vial to a patient, possibly by way of an infusion bag, takes place under satisfactory conditions and also so that an air contamination imparted by the injection needle during the transfer is avoided.
  • the bottle connector comprises a neck element to which an injector can be fixedly coupled, and second connection means to connect the bottle connector to the drug bottle.
  • the connector has a hollow needle to penetrate a closure on the bottle.
  • a fluid transfer channel is arranged within the hollow needle.
  • the bottle connector further comprises a pressure compensating means comprising a flexible container and a gas channel within the hollow needle for transporting gas from the bottle to the flexible container or vice versa in order to allow fluid to be transferred via the fluid transfer channel.
  • the gas channel includes a filter to prevent liquid passage into said flexible container as this may damage the flexible container.
  • the above mentioned connector has some drawbacks, one drawback is that the filter can be blocked. If the filter is blocked, the function of the flexible container is reduced and the pressure inside the bottle can instantly increase or decrease to levels which could cause difficulties with respect to handling. As mentioned above when dealing with cytotoxic drugs, radio-labelled or allergy-inducing substances, pressure increases or decreases inside the bottle can be hazardous, since in theory, it could lead to an increased risk of leakage. It therefore seems to be a need for additional improvements in this field.
  • the vial adaptor has a housing, an expandable chamber, a filter to prevent fluid from entering the expandable chamber.
  • a check valve is arranged in the proximity of the filter to enable a one way fluid flow.
  • the connector is however not very flexible in terms of handling nor does it provide any means by which the filter can be prevented form being obstructed, i.e. clogged.
  • the teaching of the publication is further that it is preferable that the check valve has as low cracking pressure as possible.
  • the above mentioned drawbacks are at least partly solved by means of a connector device according to the present invention. More precisely they are solved by a connector device for establishing fluid communication after connecting with a first fluid container and a second fluid container.
  • the connector device comprises a housing which in turn comprises first connection means having a pierceable barrier member to connect the first fluid container, and second connection means, to connect the second fluid container, and a fluid transfer channel to enable fluid communication between the first and second fluid containers after assembly.
  • the housing further comprises at least one pressure normalization channel arranged to normalize the pressure in the second fluid container during fluid transfer.
  • the at least one pressure normalization channel has an outlet opening, an inlet opening, a barrier filter and at least one valve arrangement.
  • the at least one valve arrangement is arranged to permit fluid to flow in a first and a second direction wherein the first direction is in a direction from the inlet opening towards the outlet opening and the second direction is from the outlet opening towards the inlet opening. Furthermore, the at least one valve arrangement has a cracking pressure in the first direction.
  • the connector device provides for a connector device which has an improved valve arrangement which effectively provides for a clogging protection arrangement with respect to the barrier filter; while at the same time enable fluid communication in two directions.
  • the first check valve and its cracking pressure enable a build up of pressure in the pressure normalization channel which partly prevents fluid from the second fluid container to reach the barrier filter during administration if the assembly for instance is; shaken; held up side down; laid down on the side or; when an excessive amount of medicaments and possibly air are returned to the second fluid container.
  • the at least one valve arrangement comprises a first and a second check valve to enable the fluid flow in the first and the second direction.
  • the first and the second check valve are preferably arranged in opposite directions and/or substantially parallel of each other.
  • the main function is however that the first and the second check valve enable a fluid flow in the first and the second direction.
  • the cracking pressure of the first check valve is at least 0,04 atm, preferably between 0,04 - 0,5 atm.
  • the cracking pressure of 0,04 atm is enough to provide for the clogging preventing function while at the same time not impart a cracking pressure which makes the handling uncomfortable or difficult for a user, when the user is administrating or retracting medicament from the second fluid container. It has been found that a to high cracking pressure can cause a user to use an excessive amount of force during which other accidents can occur such as the device can slip from the users hands.
  • the second check valve has a cracking pressure in the second direction of less than 0,5 atm, preferably less than 0,25 atm, even more preferably less than 0,1 atm and most preferred of less than 0,02 atm. It may optionally be between 0,02-0,5 atm, 0,02-0,25 atm or 0,02-0,1 atm.
  • the housing can be arranged with at least a first and a second pressure normalization channel.
  • the first check valve is then arranged in the first pressure normalization channel and the second check valve is arranged in the second pressure normalization channel.
  • This embodiment can be advantageous for manufacturing reasons.
  • the first and second pressure normalization channels may or may not further have mutual inlet- and outlet openings. Optionally they can have mutual inlet opening and separated outlet opening or vice verse.
  • the at least one valve arrangement comprises a membrane having at least one slit.
  • a membrane provides for a cracking pressure in both the first and the second direction.
  • an expandable bladder is arranged at the outlet opening of the at least one pressure normalization channel and in communication with the at least one pressure normalization channel. As such, gas which has passed through the barrier filter is not exposed to the environment but collected in the volume defined by the expandable bladder.
  • the expandable bladder is preferably connected with a parabolic formed disc.
  • the volume of the pressure normalization channel between the first check valve and the inlet opening of the pressure normalization channel is preferably relatively small.
  • the volume can be ⁇ 1 ml, preferably between 0,01 ml - 0,9 ml. This enables a pressure build up inside the pressure normalization channel which effectively prevents parts of the fluid from reaching the barrier filter which thereby could cause clogging of the filter.
  • the present invention relates to a connector device to connect a first and a second fluid container, directly or indirectly.
  • the connector device exhibit a first and a second connection means, a pierceable barrier member, a piercing member, a fluid transfer channel and a pressure normalization channel.
  • the pressure normalization channel is arranged to normalize an increasing pressure inside second fluid container.

  • the present invention provides for a connector device which reduces the risk of clogging the barrier filter.
  • the present invention can be said to provide a fluid barrier to the barrier filter by means of the check valve arrangement and preferably the first and the second check valve.
  • the check valve arrangement provides directly for a hurdle, but also indirectly due to the pressure build up in the fluid transfer channel, for the fluid while permitting gas to pass the check valve arrangement and at the same time permit gas and fluid to flow in both the first and the second direction.
  • the present invention also relates to a valve arrangement, as described above, for a medical device, preferably a connector device, having a fluid flow channel with an inlet opening and an outlet opening, such as a pressure normalization channel for reducing a pressure build up in a connected fluid container.
  • the valve arrangement comprises a first and a second check valve arranged in parallel with each other so that after assembly to the fluid flow channel, the valve arrangement is arranged to permit fluid to flow in a first and a second direction, wherein the first direction is in a direction from the inlet opening towards the outlet opening and the second direction is from the outlet opening towards the inlet opening, wherein at least the first check valve has a cracking pressure. Both the first and the second check valves can be provided with a cracking pressure.
  • the valve arrangement is further described with reference to figures 1-5 below.
  • FIG. 1 shows in a cross sectional view a connector device 10 for establishing fluid communication between a first container and a second container, according to one embodiment of the present invention.
