Description

  The present invention relates to a connection device for use in a medical fluid transfer arrangement, the connection device comprising first and second parts that are generally cylindrical, the first part comprising a hollow piercing member having an internal channel. The second part includes a bottle connecting member. The invention also relates to a method for adapting the connection device to a medical bottle.

  A major problem associated with drug preparation, drug administration, or other similar handling of pharmaceuticals is the risk of exposing medical and pharmacological staff to drugs or solvents that can escape into the surrounding air. This problem is particularly acute when harmful drugs such as cytotoxins, antiviral drugs, antibiotics and radiopharmaceuticals are a concern. It has been found that the environmental protection provided by current technology safety boxes is often inadequate. For example, cytotoxins can evaporate at room temperature. Current technology safety boxes and cabinets are equipped with a filter for circulating air and a filter for exhausting air. Traditional or HEPA (High Efficiency Particulate Capture) filters can trap airborne particles and particulates, but cannot trap vaporized material. In addition, suspended particles and other particulates that are initially trapped in the filter can change to their gas phase and be released into the surrounding air. For these reasons, systems have been developed for handling and managing drugs and other medical substances under improved and safe conditions.

  Patent Document 1 (Gustav) discloses a fluid transfer device for preventing air pollution when transferring a substance from a first container to a second container. The apparatus can be attached to and connected to a container, and includes a puncture member having a passage, for example, a first member in which a needle is enclosed. The first member has a seal member, such as a membrane, through which the needle can be inserted. The apparatus further includes a second chamber that is removably connectable to the first member and has a seal member, eg, a membrane. When the first and second members are connected to each other, the two sealing members are arranged in a predetermined position relative to each other so that a piercing member movable relative to the sealing member can penetrate them. ing.

  These seal members are liquid and gas impermeable barriers that have the ability to seal tightly after penetration and evacuation of the puncture member in order to prevent leakage of liquid components as well as gas components.

  In another system for handling drugs and other medical substances, U.S. Patent No. 6,057,836 (Fouls et al.) Discloses a connection device for establishing fluid communication between a first container and a second container. The connection device includes a first sleeve member having first and second ends. The first sleeve member has a first attachment member at the first end adapted to be attached to the first container. The connection device further includes a second sleeve member having first and second ends. The second sleeve member can be combined with the first sleeve member and movable relative thereto from the inoperative position to the activated position, the second sleeve member having a second mounting member at the second end; And adapted to attach the second sleeve member to the second container.

  The connection device disclosed in Patent Document 2 further includes a first puncture member and a second puncture member protruding from one of the first and second sleeve members, and a fluid flow path from the first container to the second container. Be prepared to provide. The connecting device further provides means for independently sealing and sealing the first and second members.

  Yet another system for handling dangerous drugs is disclosed in US Pat. U.S. Patent No. 6,057,051 refers to a fluid transfer assembly comprising a bottle connector having a hollow puncture needle, a drug bottle having a bottle closure, and a neck element having a locking member for irreversible coupling of the connector and the bottle. ing. The neck element and the connector are for guiding the hollow puncture needle to penetrate the bottle closure at a predetermined angle when establishing a means for irreversible interconnection and a fluid transfer line through the connector to the vial. And interactive guide means.

  The present invention will be described in more detail with reference to the accompanying drawings.

  FIG. 1 shows a bottle connector 1 according to the present invention with each part separated. The bottle connector 1 shown in FIG. 1 includes a first part 2 that is generally cylindrical with a first end 4 and a second end 5 and a second that is generally cylindrical with a first end 6 and a second end 7. Part 3 is provided. The bottle connector 1 further includes a barrier member 8 and a puncture member. A parabolic gas chamber 10 belonging to the pressure equalizing member 11 is shown to be connected to the first part 2 of the bottle connector 1. Further parts of the pressure equalizing member 11 are a filter 12, a filter holder 13 and a flexible wall member 14.

  The barrier member 8 is represented in a generally disc shape with a thicker central portion and a thinner peripheral portion. The barrier member may be of any type that seals the membrane or diaphragm as defined herein.

  When assembled, the pressure equalizing member 11 is configured to adapt its volume in response to changes in gas pressure. The volume of the pressure equalizing member 11 can be changed by expanding or collapsing the flexible wall member 14. The flexible wall member 14 may be a thin film material and is welded to the outer rim 15 of the parabolic gas chamber 10 to form an airtight seal between the parabolic gas chamber 10 and the flexible wall member 14. For example, it can be a thin transparent film attached or attached.

  Any gas that passes through the gas container formed between the parabolic gas chamber 10 and the flexible wall member 14 passes through the filter 12 in the filter holder 13. Filter 12 may be any suitable commercially available filter such as a particulate air filter having a pore size of 0.2 μm. In FIG. 1, the filter holder 13 is illustrated as being separate from the parabolic gas chamber 10, but may be formed integrally with the parabolic gas chamber 10 by a blow molding or vacuum forming process. If formed as a separate component, it may be attached to the parabolic gas chamber 10 by welding, such as ultrasonic welding as is known in the art. Adhesive application or mechanical attachment is also contemplated within the scope of the present invention. The filter 12 may be attached to the filter holder 13 by bonding or welding, or may be mechanically held in the filter holder 13.

  The pressure equalizing member 11 shown in the figure should not be considered as limiting the present invention. Therefore, although a closed pressure equalizing member is very preferable when handling harmful substances, the pressure equalizing member may take a form including an unclosed arrangement. An example of a suitable pressure equalizing member is found in US Pat.

  The puncture member 9 has an internal flow path 16 that is in fluid communication with the pressure equalizing member 11 when the bottle connector 1 is assembled. The internal flow path 16 allows gas and air to enter a volume change gas container formed between the parabolic gas chamber 10 and the flexible wall member 14.

  FIG. 2 a shows the first part 2 of the bottle connector 1 in FIG. 1, as seen from the second end 5, together with the parts of the assembled pressure equalizing member 11, without the puncture member 9. The first part 2 of the bottle connector 1 has a substantially cylindrical shape having a large diameter portion 22 at the second end portion 5 and a small diameter portion 23 at the first end portion 4. The wider second end 5 is adapted for connection with the second part 3 of the bottle connector 1 and the narrower first end 4 is adapted for connection with a medical device. In the illustrated example, the medical device is a syringe as shown in FIG.

  In order to allow a connection between the first part 2 and the second part 3 of the bottle connector 1, the first part is a first locking opening 17 arranged opposite to each other on the wall of the second part. The first and second parts 2 and 3 are releasably locked in the first configuration of the transfer configuration and the first member of the snap-lock receiving member or female member is configured. A locking opening 17 is provided. The first locking opening 17 is between the edge of the second end 5 of the first part 2 and the edge of the first part 2 and the edge of the first part 2 on the second part 3 side. The guide groove 18 is disposed at a distance that leaves room for the guide groove 18.

  The second set in the form of the second locking opening 19 of the receiving member is arranged at the joint between the large diameter portion 22 of the bottle connector 1 and the small diameter portion 23 of the first part 2. The second locking opening 19 also forms part of the snap lock arrangement between the first and second parts 2, 3 of the bottle connector 1. The second locking opening 19 is used to lock the first and second parts 2 and 3 in the second configuration constituting the fluid transfer configuration. The arrangement shown in the figure with opposing connecting members may be preferred, but any arrangement that allows for telescopic movement without simultaneous rotation between the first and second parts 2 and 3 can be used. It can be used within the scope of the invention. Accordingly, parts 2 and 3 of the bottle connector 1 may include one or more connecting members, for example 1 to 6 connecting members. When more than one connecting member is used, the connecting members are preferably arranged symmetrically on the wall of the bottle connector 1. Also, the locking mechanism between parts 2 and 3 can be any one or more locking means such as bayonet fitting, stop notch, stop knob, snap lock, etc., as known in the art. May contain many.

  The first part 2 of the bottle connector 1 further includes a groove 20 constituting a female guide means for guiding the second part 3 to the first part 2.

  The first part 2 of the bottle connector 1 is further shown to have an intermediate wall 21 between the large diameter portion 22 at the second end 5 and the small diameter portion 23 at the first end 4. A central opening 24 is disposed in the intermediate wall 21 adjacent to the circular seal flange 25. The central opening 24 is compatible with both a socket 26 for the piercing member 9 and a channel 27 for an external piercing member, such as a syringe needle. The circular seal flange 25 ensures that an airtight seal is created around the puncture site when the bottle connector 1 is applied to a pharmaceutical bottle. An alternative seal configuration includes the use of small diameter spikes with two internal channels for fluid and gas transfer.

  Further features of the first part 2 of the bottle connector 1, as shown in FIG. 2 a, are arranged in the small diameter part 23 of the first part 2 for the connection of a syringe or similar device to the bottle connector 1. It is a female member 28 of bayonet fitting. It should be noted that both the small diameter portion 23 of the first part and the bayonet fit are optional features of the bottle connector according to the present invention.

  Depending on the type of medical device coupled to the first end 4 of the first part 2, the coupling device at the first end 4 and the illustrated bayonet fit may be different. Thus, any type of thread coupling, bayonet fitting, snap lock, lock ring, slide fitting, clamp, etc., known in the art can be used. In addition, more than one locking element of the same or different structure can be used in combination to create a bond between the bottle connector 1 and the medical device.

  If the bottle connector 1 is connected to a first medical device, it can subsequently be connected to a second medical device carrying a puncture member. Therefore, the medical device connected to the bottle connector 1 at the first end 4 of the first part 2 of the bottle connector 1 may be a puncture device such as a syringe, another connection device, a needle protection device, or the like.

  A second part 3 of the bottle connector 1 is shown in FIG. 2, which is a second end that is located remotely from the second end 5 of the first part 2 when the bottle connector 1 is assembled. It is represented from the end 7.

  The second part 3 of the bottle connector 1 comprises two flexible locking tongues 30 arranged opposite each, each carrying a locking projection 31, which respectively For locking in the transfer configuration and the fluid transfer configuration, it is arranged to cooperate with the first locking opening 17 and the second locking opening 19 of the first part 2 of the bottle connector 1.

  The second part 3 of the bottle connector 1 further comprises an opposing male guide element 32 arranged to engage the guide groove 20 of the first part of the bottle connector 1. In the illustrated embodiment, the male guide element 32, together with the locking projection 31, also serves to limit the movement of the second part 3 into the first part 2. The dimensions of the locking projection 31 and the guide element 32 determine the axial force necessary to activate the telescopic movement between the first and second parts 2, 3.

  As with the connecting member, the configuration of the guiding means and the locking member shown in the drawings and described herein should not be considered as limiting the bottle connector of the present invention. Therefore, the arrangement may be reversed, the groove arranged in the second part, and the protrusion engaging the groove arranged in the first part. Also, the number of guide arrangements and the number of locking members may be different from the two arrangements shown in the figure, for example, 1 to 5 guide arrangements, 1 to 5 engagement arrangements, etc. The guiding and locking functions may be fulfilled in one arrangement or the same arrangement. If more than one guiding / locking arrangement is provided, the guiding arrangements are preferably arranged symmetrically.

  The first end 6 of the second part 3 has an end wall 33 having an end opening 34. When the bottle connector 1 is in a fluid transfer configuration, the end wall 33 of the second part 3 will be in direct contact with the intermediate wall 21 of the first part 2 and the relative axial directions of the parts 2 and 3 Prohibit further compression movement. In the fluid transfer configuration, the circular seal flange 25 on the first part 2 of the bottle connector 1 extends through the end opening 34 in the end wall 33 of the second part 3.

  The second end 7 of the second part 3 is provided with a hook element 35. The hook element 35 is configured to fit into the bottle neck and keep the bottle connector 1 locked to the bottle. In order to facilitate the fitting of the bottle connector 1 to the bottle, the side wall of the second part 3 of the bottle connector 1 is split so that it can bend slightly outward as the bottle connector 1 is pushed down over the bottle neck. The sexual tongue 36 is produced. The flexible tongue 38 may be two or more, for example 2 to 30 flexible tongues. The hook element 35 is arranged at the free end of the flexible tongue 36. Apart from this, the side wall of the second part 3 may be provided with a slit extending in the axial direction of the second part 3.

  3a and 3b represent a bottle connector 1 having an axial direction A and a radial direction R perpendicular to the axial direction A, appearing assembled in a transfer configuration. The cross section in FIG. 3 a is taken through the center of the bottle connector 1 in a plane passing through the first locking opening 17 and the second locking opening 19 of the second part 2 of the bottle connector 1. The pressure equalizing member 11 is not shown in the figure because there is a display in a direction away from the puncture member 9 and the pressure equalizing member. The puncture member 9 is also not seen in FIG. 3a because the puncture member 9 is arranged slightly offset from the central axis passing through the bottle connector 1 in the direction toward the pressure equalizing member 11. The cross section in FIG. 3 b is taken in a plane perpendicular to the plane in FIG. 3 a and extends through the pressure equalizing member 11 and the hollow puncture member 9.

In the transfer configuration represented in FIGS. 3 a and 3 b, the bottle connector 1 has a maximum length L ₁ in the axial direction of the bottle connector 1. The maximum length L ₁ is larger than the length L _FP of the first part 2 of the bottle connector 1. As seen in FIG. 3a, even when the bottle connector 1 is in the fluid transfer configuration, even though the tip 40 of the piercing member protrudes slightly beyond the second end 5 of the first part 2 of the bottle connector 1. The second part 3 of the bottle connector 1 extends past the distal end portion 40 of the puncture member 9 in the axial direction A so that the puncture member 9 is completely shielded in the radial direction R.

  FIGS. 3 a and 3 b show the barrier member 8 attached to the barrier member holder 37 in the center of the first part 2 of the bottle connector 1.

  The first and second parts 2 and 3 of the bottle connector 1 are locking protrusions 31 on the flexible locking tongue 30 on the second part 3, and the first engagement on the first part 2. It is connected in advance by a locking projection 31 inserted into the stop opening 17. The connection between the parts is preferably made so as to prevent the user from separating the parts 2 and 3 deliberately or mistakenly, but allowing intentional compression and compression of the parts 2 and 3 .

  Figures 4a and 4b represent the bottle connector 1 appearing assembled in a fluid transfer configuration. The cross sections in FIGS. 4a and 4b correspond to the cross sections in FIGS. 3a and 3b.

  In the fluid transfer configuration, the first end 6 of the second part 3 of the bottle connector 1 contacts the intermediate wall 21 of the first part 2 of the bottle connector 1 and the locking tongue 30 on the second part 3. Until the upper locking projection 31 engages with the second locking opening 19 on the first part 2 of the bottle connector 1, the first part 2 of the bottle connector 1 is connected to the second part 3 of the bottle connector 1. The bottle connector 1 is compressed in the axial direction A by being slid above or pressed down. During compression of the bottle connector 1, the guide groove 20 on the first part 2 of the bottle connector 1 cooperates with the male guide element (protrusion) 32 on the second part of the bottle connector 1, so that the puncture member 9 is Ensure that it is guided at a predetermined angle relative to and through the stopper. The puncture member 9 is preferably guided at an angle of 90 ° via a bottle stopper. However, other angles are considered within the scope of the present invention, such as an angle between 85 ° and 95 °.

Bottle connector 1 in fluid transfer arrangement has a minimum length L _2, which is represented to be the same as the length L _FP of the first part 2 of the bottle connector 1. The minimum length L ₂ of the bottle connector 1 need not be equal to the length L _FP of the first part 2 of the bottle connector 1. However, the minimum length L ₂ is always shorter than the maximum length L ₁ of the bottle connector 1.
