Definitions

  • the invention relates to a container for medical liquids, which encloses the liquid in a germ-tight manner and makes it available for removal by a transmission device, and which also enables medication to be added to the container contents.
  • blow-fill-seal containers are known in medical technology. These are bottle-like containers made of plastic, which are manufactured using the blowing process and immediately filled with the liquid when they are produced, and then sealed in a germ-tight manner.
  • a cap is placed on a container neck, which is tightly and permanently connected to the container body along an annular collar by extrusion coating or mirror welding.
  • the protective cap contains a pierceable rubber membrane which is arranged under a tearable section of the end wall of the protective cap. After the end wall has been torn off, the spike of a transmission device can be pierced through the membrane to let liquid run out of the container. It is possible to add medication to the container contents by piercing the membrane with a syringe needle and then injecting the medication into the container through the needle.
  • Such containers are sold under the name "Ecoflac”.
  • the invention has for its object to improve a container of the type described with regard to security against contamination and to facilitate a defined docking of external devices.
  • the protective cap with which the container is sealed is provided with at least two ports, namely a removal port and an addition port.
  • a removal port In order to gain access to the interior of the container, it is not necessary to tear off a larger area of the protective cap and to expose a membrane located underneath. Rather, it is sufficient to remove the tear-off closure part only from the port that is to be used.
  • the associated transmission device can be inserted into the relevant port, the removal port being expediently designed such that it is suitable for all common removal transmission devices. This means that an access channel is opened, the cross-section of which is not significantly larger than that of conventional piercing mandrels of removal transmission devices.
  • the sealing element over a large area, which consists of a pierceable membrane or a mechanically opening valve is avoided. Since no large areas of the sealing element located under or in the port are exposed when the respective port is opened, the risk of contamination of the sealing element is reduced. For example, the sealing element cannot be reached with the fingers.
  • the port enables the respective transmission device to "dock", which can be reversibly attached to the port and does not have to hold onto the closure part.
  • Another advantage of using two ports is that it is possible to attach the transmission devices in a directed manner.
  • Each of the transmission devices is aligned by the pipe socket of the relevant port, so that the transmission devices do not hang obliquely to one another, appearing randomly and disorderly, on the protective cap.
  • At least one of the closure parts is preferably a crushing gag which has a grip part and a protective plate between the grip part and the predetermined breaking line.
  • the protective plate protects the breaking edge on the protective cap side at the predetermined breaking line of the closure part against contact contamination by the hand acting on the grip part. It forms a protective shield, which prevents the hand from getting close to the predetermined breaking line when the crimping gag is unscrewed.
  • a latching edge for holding a protective cover is expediently provided on the addition port.
  • This protective cover makes it possible to add the port after adding a drug to the container to close again.
  • the protective cover can be irreversibly attached to the locking edge. This means that after the first application, the protective cover can no longer be removed from the addition port without damage. In this way, tamper-evident is achieved with which the subsequent addition of substances to the container contents is prevented or at least made recognizable.
  • a blow-fill-seal container 10 is provided, on the container neck 11 of which a protective cap 12 is placed.
  • the container neck 11 and the protective cap 12 are provided with superimposed flanges which, by extrusion coating or mirror welding, form an annular collar 13 are united.
  • the protective cap 12 has the shape of an inverted round cup.
  • Two pipe sockets 14, 15 project vertically from their end wall.
  • the pipe stub 14 is part of the removal port 16 and the pipe stub 15 is part of the addition port 17.
  • the pipe stub 14 is closed by an integrally molded closure part 18, which seals along a predetermined breaking line 19, which is a weakening line, with the end of the pipe socket is connected.
  • the closure part 19 is designed as a crushing gag, that is to say it has a wing-shaped grip part 20 which can be gripped between the thumb and forefinger in order to rotate the closure part 18 and detach it from the pipe socket 14 along the predetermined breaking line 19.
  • a protective plate 21 is formed on the closure part 18, the diameter of which is larger than that of the predetermined breaking line 19.
  • the protective plate 20 covers the predetermined breaking line 19 and forms a protective shield which prevents the predetermined breaking line from being touched by hand.
  • an annular latching edge 22 is provided on the pipe socket 14, which laterally projects beyond the pipe socket.
  • the predetermined breaking line 19 is located between the laterally projecting locking edge 22 and the protective plate 21 in a constricted area and is not accessible by hand.
  • the circumferential, laterally projecting locking edge 23 is also provided on the pipe socket 15 of the addition port 17.
  • the predetermined breaking line 24 is located above it, on which the closure part 25 is connected to the end wall of the pipe socket 15.
  • the closure part 25 is formed with a protective cover 26 which, after breaking off the closure part, can be placed on the pipe socket 15 which is then open and which latches onto the latching edge 23.
  • This detent is preferably irreversible, so that the protective cover 26 can no longer be removed from the pipe socket 15 after it has been placed on it.
  • the protective cover 26 is located at the end of the closure part 25 facing away from the predetermined breaking line 24.
  • a grip wing 27, which projects radially from the protective cover, serves to make it easier to unscrew the closure part 25 from the pipe socket 15.
  • a membrane 30 which bears against the end wall of the protective cap 12 and covers the channels 31, 32 passing through the pipe socket 14, 15.
  • the membrane 30 has a shoulder 33 which projects into the channel 32 of the pipe socket 15.
  • the closure part 25 When using the addition port 17, the closure part 25 is twisted off the pipe socket 15 along the predetermined breaking line 24. Then the membrane 30 or the neck 33 is pierced with the needle of an injection device. The injection device can be locked reversibly on the locking edge 23. With the injection device, medication is injected through the needle into the container 10. The injection device is then removed again. The addition port 17 is closed with the protective cover 26.
  • the closure part 18 of the removal port 16 is unscrewed from the pipe socket 14.
  • the spike of a transmission device is then inserted into the channel 31, the tip of the spike penetrating the membrane 30.
  • the piercing mandrel is guided closely in the channel 31.
  • cooperating locking elements can be provided on the channel 31 under the spike, which e.g. Grasp like a bayonet catch and prevent the spike from being pulled out axially.
  • the locking edge 22 also serves to lock a transmission device on the pipe socket 14. After connecting the transmission device to the removal port 16, the container 10 is hung upside down so that the liquid can drain out of the container through the transmission device.
  • FIG. 4 The embodiment of FIG. 4 is largely the same as the first embodiment, so that the following description can be limited to the differences.
  • the protective cover 26 is integrally formed to close the opened addition port 17 of the protective cap 12.
  • a flexible tab 35 is provided which connects the protective cover 26 to any part of the protective cap. The tab 35 does not prevent the closure part 25 from being twisted off and allows this closure part to be turned over in order to place the protective cover 26 on the pipe socket 15.
  • only the channel 32 of the pipe socket 15 contains a pierceable membrane 36.
  • the channel 31 of the pipe socket 14 can be designed such that it is filled in sealingly by the spike of the transmission device. Alternatively, there is the possibility of providing a valve in the channel 31 that is opened when the transmission device is inserted or that the pipe socket 14 is sealed on the outside at the latching edge 22.
  • the removal port 16 is configured in the same way as in the preceding exemplary embodiments.
  • the addition port 17 is closed with a closure part 25 which is designed without a protective cap and here consists of a simple handle part which is provided with a protective plate 37, similar to the protective plate 21 from FIG. 1.
  • the handle part is provided with an "I”, which denotes the "infusion port” and in the closure part 28, the handle is provided with an "A”, which denotes the "addition port”.
  • FIG. 6 corresponds to that of FIG. 5, only the design of the addition port 17 having been changed in such a way that the grip wing 27 has the overall shape of the letter "A" for "addition port".
