Definitions

  • the invention relates to a closure cap for a receptacle for holding a medical fluid according to the preamble of claim 1.
  • Such a closure cap comprises a cap body which delimits an interior space and has at least one opening. At least one connection device is arranged on the cap body, to which a conveying device for supplying a medical liquid into the container or for removing a medical liquid from the container can be connected.
  • the connection device has a sealing element arranged on the cap body, which is arranged at the opening for sealing closure.
  • a conveyor device for connecting the conveyor device can be attached to an outside of the sealing element facing away from the interior.
  • Such a conveying device can be configured, for example, as an injection syringe, which can be attached to the sealing element with an injection cannula and inserted into the sealing element in an attachment direction, so that the sealing element is pierced by the injection cannula.
  • an injection syringe is used in particular to supply a medical liquid into the container.
  • an infusion set can be used, for example, which is attached to the sealing element with a mandrel, which is also referred to as a spike, in such a way that the sealing element is pierced by the mandrel and thus creates access to the container becomes.
  • connection devices are provided, each with a sealing element.
  • One of these connection devices is used to supply a medical liquid into a container connected to the closure cap, for example a bottle, while the other connection device is used to remove a medical liquid from the container.
  • connection devices are provided, of which a first one is used to supply a medical liquid by means of an injection syringe, a second one is used to remove a medical liquid by means of an infusion set that has a mandrel and a third one is used to provide a so-called needle-free access.
  • the sealing element of the third connection device has a slot opening which makes it possible to attach a conveying device, for example a syringe, to the sealing element with a —needeless — connecting piece in order to open the sealing element and in this way to supply a liquid to the container.
  • a sealing element is provided which is convex on the outside.
  • Legal requirements may make it necessary to wipe or dab the outside of the sealing element before disassembling a conveying device, for example an injection syringe for supplying a medical liquid or an infusion set for removing a medical liquid.
  • the object of the present invention is to provide a closure cap in which the disinfection of a sealing element arranged thereon is simplified.
  • the closure cap according to the invention closes access to a container.
  • the cap closes the opening in the bottle neck of a bottle.
  • the sealing element is convex on its outside.
  • the outer side of the sealing element protrudes outwards from an upper side of the cap body.
  • the sealing element is convex on the outside, it can be ensured that after wiping or dabbing no disinfectant liquid remains on the sealing element, but can be removed in a reliable, simple manner by wiping or dabbing. Because the outside of the sealing element protrudes outwards from an upper side of the cap body, the sealing element can be easily accessed by wiping along the upper side with a suitable disinfection tool, for example a swab or a wiping cloth, in this way dab or wipe the outside of the sealing element.

  • a break-off piece is connected to the cap body in such a way that the sealing element is completely covered on the outside.
  • the break-off piece encloses the outside of the sealing element and thus closes the outside from the outside, so that no dirt in the form of solid or liquid contaminants can get onto the outside.
  • the break-off piece is integral, that is to say in one piece, connected to the closure cap.
  • the closure cap can, for example, be produced together with the break-off piece as a molded plastic part, for example by means of plastic injection molding.
  • the break-off piece is connected to the cap body via a predetermined breaking point in such a way that the break-off piece can be separated from the cap body along the predetermined breaking point, in particular broken off, in order to remove the break-off piece from the cap body.

  • an interior or space between the break-off piece and the outside of the sealing element is provided sterile.
  • the outside of the sealing element is thus already sterile in the state in which the break-off piece is still connected to the closure cap. Disinfecting the outside of the sealing element after removing the break-off piece and before attaching a conveyor, in particular by wiping or dabbing, is no longer necessary in this case. However, if, for example, legal requirements make such disinfection necessary, this additional disinfection can be carried out more easily, in particular by the convex outside of the sealing element.
  • the closure cap can have, for example, a first connection device for removing a medical liquid and a second connection device for supplying a medical liquid.
  • a first connection device for removing a medical liquid and a second connection device for supplying a medical liquid.

  • the same sealing elements are thus used on the connection devices, it being possible for identical holding devices to be provided on the connection devices, for example in the form of cutouts provided on the closure cap for receiving the sealing elements. This simplifies the overall design of the closure cap because the same parts can be used to manufacture the connection devices.
