[0110] The closure cap 40 is shown engaged with the port 20, featuring a cap body 41 that fits securely over the port head section 23. The cap body 41 includes an inner notch 413 and a teeth-shaped structure 414, which interact with the anti-rotation toothing 234 and the locking ridge 233 on the port head section 23, ensuring that the closure cap 40 remains securely in place.
[0111] Central to the system is the port 20, which connects to the medical container 100 to facilitate fluid transfer. The port 20 includes a port foot section 21, with a foot section base 211 that anchors the port securely to the container. The weld rip 212 and weld flag 213 are integral to the foot section 21, ensuring a strong weld to the container's surface, which maintains the structural integrity of the connection even under stress.FK23023-05-PAT-WO Fresenius Kabi Deutschland GmbH
[0112] The port head section 23 features an upper locking ridge 233, a lower ridge 231 and antirotation toothing 234 above the upper locking integrated into the design. The port head section 23, equipped with the anti-rotation toothing 234, is designed to interact with the closure cap 40, preventing any rotational movement that could compromise the seal. These features are advantageous, ensuring that the closure cap 40 remains securely engaged with the port 20, thereby maintaining a reliable seal.
[0113] Within the port 20, the port channel 221 serves as the conduit for fluid flow. This channel 221 is designed for optimal fluid dynamics, allowing fluids to move smoothly and efficiently from the container 100 to the administration set or other connected devices.
[0114] The sealing element 30 is a critical component, prominently displayed in this sectional view. The sealing element 30 is supported by a sealing body 312, which is connected to a ring collar 314 via a flange 313 (see also Fig. 6Ato 6D. The sealing head 310, with its flat outer side 311, ensures consistent pressure distribution and contact, crucial for maintaining a fluid-tight seal. The sealing body 312 supports the sealing head 310 and is connected to the ring collar 314 via the flange 313. This configuration provides structural support and distributes mechanical stress, enhancing the durability and longevity of the sealing element 30.
[0115] FIG. 4Ato 4C illustrate different views on the port system or port 20. The port 20 is integral to facilitating fluid transfer from the medical container 100, and its design ensures both secure attachment and reliable operation.
[0116] FIG. 4A provides a perspective view of the port 20, highlighting its structural design and the features that enable its secure integration into the medical container 100's connection system 101. The port 20 features the port head section 23 with upper ridge 233, lower ridge 231 , and anti-rotation toothing 234 above the upper ridge 233. These features ensure secure engagement with the closure cap 40. Feature 234 prevents rotational movement.
[0117] The anti-rotation toothing 234 is embodied as a kind of serrated flange above the upper locking ridge 233. The upper locking ridge is directly adjacent to the anti-rotation toothing 234 or merges into the anti-rotation toothing 234. The anti-rotation toothing 234 can be integrated into the upper locking ridge 233 as well (not shown). FIG. 4B provides a side view of the port 20, showing the upper locking ridge 233 which is accommodated in inner notch 413 of the closure cap 40 for a snap-fit connection, ensuring stability and a fluid-tight assembly.FK23023-05-PAT-WO Fresenius Kabi Deutschland GmbH
[0118] At the foundation of the port 20 is the port foot section 21, which includes several key components that anchor the port securely to the container. The foot section base 211 provides a sturdy foundation, enhancing the port's 20 stability when welded to the container 100. The weld rip 212 and weld flag 213 are advantageous for achieving a robust weld to the container's 100 surface, ensuring the structural integrity of the connection even under stress.
[0119] FIG. 4D presents the port 20 in a sectional view, revealing internal configurations such as the port torso section 22 and port head section 23, which supports the sealing element 30 and contribute to consistent performance. The port channel 221 is clearly visible in this presentation, illustrating its role as the conduit for fluid flow from the container 100. As can be seen the ports, in particular the port torsos 22 and the port head sections 23, for the administration connector 101a and the injection connector 101 b are of the same configuration. Both tubular channels 221 are supported by one single foot section 21. Thereby a double-port 20 is provided.
[0120] FIG. 5A showcases a perspective view of the closure cap 40, exemplary for the administration connector 101a. The closure cap 40 for the injection port 101b is not illustrated here. The closure cap 40 for the injection port 101b has the same geometry and the same dimension. The difference is that the arrow 411 on the cap body 41 and the arrow 431 on the break-part 43 point to the medical container 100 indicating the connector to be used as an injection connector 101b. Additives, as for instance trace element, vitamins, minerals and / or drugs can be injected into the container 100 before (patient) administration.
[0121] The closure cap 40 is constructed with a cap body 41 that forms the primary structure of the cap. This cap body 41 is designed to fit snugly over the port head section 23, ensuring a secure and fluid-tight seal. The cap body 41 features an upper side 412, which provides a smooth surface for handling, e.g. disinfection. The closure cap 40 is equipped with the break-off part 43, which serves as a tamper-evident component. This part must be removed before the connector can be used, ensuring that the contents of the medical container 100 remain sterile until first use. The break-off part 43 is designed to detach with suitable effort, allowing for quick access while maintaining the cap's integrity. The shown cap body 41 features an upper side 412 and a break-off part 43 for tamper-evidence, with an arrow 411 indicating the correct use of the connector as an administration connector 101a to withdraw medical liquid form the medical container 100 for (patient) administration.
[0122] FIG. 5B shows a side view of the closure cap 40, emphasizing its ergonomic profile for easy handling and the break-off region 42 between cap body 41 and the break-off part 43. TheFK23023-05-PAT-WO Fresenius Kabi Deutschland GmbH
[0123] break-off part 43, which extends from the cap body 41, serves as a tamper-evident feature, ensuring that the content of the medical container 100 remains sterile until the cap 40 is intentionally opened. The break-off part 43 is engineered to be removed with suitable effort, providing quick access to the interior of the container while maintaining the integrity of the seal. On the exterior of the closure cap 41 , the arrow 411 is visible. This arrow 411 acts as a directional indicator, guiding users on the use of the connector.
[0124] FIG. 5C depicts the closure cap 40 in a sectional view, illustrating features like the innertubular section 415 which accommodate the sealing head 310 of the sealing element 30. Its design also ensures that the sealing element 30 is properly aligned and supported within the cap body 41, maintaining a consistent and effective seal. The inner tubular section 415 and the inner side of the wall of the cap body 41 form the ring-shaped notch or recess 416. This recess 416 accommodates the ring collar 314 of the sealing element 30. This ensures a secure seal. The teeth-shaped structure 414 inside the cap body 41 interacts with the port's anti-rotation toothing 234 to prevent accidental rotation.
[0125] The ring-shaped notch 413 interacts with the upper flange 233 of the head section 23 of the port 20 to enable a stable connection between the closure cap 40 and the port 20 by a snap-fit action. The sealing element 30 is clamped between the cap body 41 of the closure cap 40 and the head section 23 of the port 20 and thereby securely positioned.
[0126] Inside the closure cap 40, the teeth-shaped structure 414 is visible. This structure 411 is designed to interact with the anti-rotation toothing 234 on the port head section 23. The engagement of these features prevents accidental rotation of the closure cap 40, ensuring that it remains securely attached and the seal remains intact during use.
[0127] Detailed illustrations of the sealing element 30 are presented in fig. 6A-6D: FIG. 6A provides a perspective view of the top side 311 of the sealing element 30. The sealing head 310 features a flat outer side 311 with a cross slot 316 for effective sealing and easy access when instruments are inserted. FIG. 6B presents a perspective view of the bottom or inner side 315 of the sealing element 30, showing the sealing body 312, the ring collar 314, and the inner side 315 that maintain its position and structural integrity within the port 20. FIG. 6C displays the top side 311 of the sealing element 30, focusing on the outer surface designed for optimal contact and pressure distribution to prevent leaks.
[0128] FIG. 6D shows the sealing element 30 in sectional views along lines A-A and B-B, detailing the internal structure and material distribution. In a side orientation the slots 316 extendFK23023-05-PAT-WO Fresenius Kabi Deutschland GmbH
[0129] through the entire sealing head 310. This can be well seen in the upper illustration of the FIG.
[0130] 6D showing the sectional view A-A along the slot 316. In the depth orientation the slots 316 do not extend through the entire sealing body 312. This can be well seen both in the upper illustration and the lower illustration of the FIG. 6D. The slots 316 extend through the entire sealing head 310. But the slots 316 extend from the upper side 311 only partially through the sealing body 312. The slots 316 end slightly below the upper side of the flange 313. The closed lower side 315 of the sealing element 30 supports maintaining sterility of the container’s interior until use.
[0131] Preferably the sealing element 30 for the administration port 101a is of the same configuration as the sealing element 30 for the injection port 101b. The sealing element 30 has a sealing head 310 having an outward pointing, substantially flat outer side 311. Adjoining the sealing head 310 - to the rear of the outer side 311 - is a sealing body 312, which is connected via a circumferential flange 313 to a likewise peripherally circumferential ring collar 314. Via the ring collar 314, the sealing element 30 lies in an opening provided the by tubular channel 415 of the cap body 41. The sealing element 30 is clampingly held between the port head section 23 and the cap body 41. A bottom side 315 of the sealing element 30 points to the interior of the medical container 100. The bottom side 315 of the sealing element 30 is here substantially flat and closed. In the sealing element 30, the top side of the ring collar 314 is situated lower than the outer side or top side 311 of the sealing head 310. Moreover, the bottom side of the ring collar 314 is situated lower than the inner side or bottom side 315 of the sealing body 312. The ring collar 314 thus extends beyond the bottom side 315.
[0132] The maximum thickness of the sealing body 312, viewed along an attachment direction in which a conveying device is to be attached to the sealing element 30, is measured between the outer side 311 and the inner side 315. The sealing element 30 reseals itself automatically when the associated conveying device is in turn removed from the administration connector 101a and / or the injection connector 101b.
[0133] The sealing element 30 has a total diameter of 8 mm to 14 mm, preferably 10 mm to 12 mm. The sealing element 30 has a total height of 3 mm to 8 mm, preferably 4 mm to 5 mm. The sealing body 312 has a thickness of 2 mm to 5 mm. preferably 3 mm to 4 mm. The sealing head 312 has a diameter of 5 mm to 10 mm, preferably of 6 mm to 7 mm. The slot 316 has an extension in the depth of at least 2 mm and less than the thickness of the sealing body 312. Preferably the slot 316 extends 2mm to 4 mm, preferably 2,5 mm to 3,5 mm in the sealing body 312. The ring collar 314 has an inner diameter of 6 mm to 12 mm, preferably 8 mm to 10 mm.FK23023-05-PAT-WO Fresenius Kabi Deutschland GmbH
[0134] Because the sealing element 30 is on its outer side 311 substantially flat and is substantially aligned with the top side 412 of the cap body 41, the sealing element 30 can be favorably dabbed or wiped for disinfection purposes, as can possibly be prescribed by legal requirements. Preferably, the outer side 311 of the sealing element 30 lies substantially in the same plane as the upper rim of the opening of the tubular channel 415. In particular, due to the shaping of the sealing element 30 on its outer side 311 and the positioning in the opening of the cap body 41 , it is possible to ensure that the outer side 311 can be reached by a suitable disinfecting tool, for instance a swab or a wiping cloth.
[0135] For the attachment of a conveying device, as for instance a spike connector of an administration set, to the administration connector 101a, the following procedure is basically adopted. Essentially the same process is applied for the attachment of a conveying device, as for instance a needle syringe, to the injection connector 101b. Generally injecting an additive into the medical container 100 via the injection port 101b takes place in an initial step. Withdrawal of the medical liquid from the medical container 100, for instance for patient administration, wound cleaning, flushing surgical sites, preparing medical preparation etc., takes places in a subsequent step.
[0136] In an initial state, the connection system 100 is closed. The break-off part or piece 43 is still fixedly arranged on the cap body 41. The break-off piece 43 is configured integrally with the cap body 41 and is connected to the cap body 41 via circumferential predetermined breaking points 42 in such a way that the outer side 311 of the sealing element 30 is outwardly covered.
[0137] If a conveying device is intended to be attached to an associated administration connector 101a or injection connector 101b, then the respective break-off piece 43 is removed from the cap body 41 by a user gripping the break-off piece 43 between his fingers and breaking it off from the cap body 41 along the predetermined breaking point 42. In this way, the sealing element 30 is exposed, so that the conveying device can be attached to the outer side 311 of the sealing element 30 (not shown in the figures).
[0138] By means of a suitable puncturing tool, the sealing element 30 is now pierced, so that a flow connection between a body of the respective conveying device and the inside of the container 100 is created, so that a medical liquid can be filled into the container 100 (via the injection connector 101b) or removed from the container 100 (via the administration connector 101a).FK23023-05-PAT-WO Fresenius Kabi Deutschland GmbH
[0139] In order to facilitate the insertion of a spike (of an administration set) or a needle (e.g. of a needle syringe) into the sealing element 30, the sealing element 30, starting from its outer side 311, is partially slotted. The slot 316 is here configured as a cross slot (see, in this regard, in particular figures 6A and 6C). This cross slot 316 serves at the same time also as a marking in order to highlight the puncture region to the user. In order to still further improve the visibility of the puncture site, also elevations or webs 317 are arranged on the outer side 311 of the sealing element 30. The insertion region for the spike on the outer side 311 of the sealing element 30, which insertion region is defined by the intersecting slots 316, is additionally enclosed by an annularly circumferential web 317. The annularly circumferential web 317 is respectively broken at several places. The slots 316 extend through the gaps. As a result, a type of target is provided for the user. The webs 317 can lie level with the opening rim of the opening 321, or else project somewhat beyond the top side 412 of the cap body 41. That is dependent on the contact pressure with which the sealing element 30 is fixed in the opening of the cap body 41.
[0140] On the top side and bottom side of the ring collar 314 of the sealing element 30, a plurality of spacers 318 are arranged distributed over the periphery. The spacers 318 are configured as elevations or webs. These here extend, by way of example, radially outward. These spacers 318 prevent or reduce adhesion of the sealing element 30 during storage. An automated gripping and insertion of the sealing element 30 into the closure cap 40 can thereby be facilitated.
[0141] The closure cap 40 is preferably be made of plastic, for instance by means of plastic injection molding. The break-off piece 43 of the closure cap 40 are herein initially formed in one piece with the cap body 41 and can be broken off from the cap body 41 in order to gain access to the sealing element 30. The port 20 is preferably be made of plastic as well, for instance by means of plastic injection molding. While the closure cap 40 is made of a comparatively rigid plastics material, the sealing element 30 is made of a comparatively soft, elastic material, for instance polyisoprene or a thermoplastic elastomer.
