Definitions

  • Removal device for the sterile removal of a liquid from a container
  • the invention relates to a removal device for the sterile removal of a liquid from a container, in particular for the removal of liquids from medical containers by means of syringes or infusion devices, according to the preamble of claim 1.
  • Devices of this type are used in particular to protect the patient from bacterial contamination.
  • DE 3820204 AI describes a device for the filtered supply or removal of liquids into or from a container, in particular a bottle, in which separate chambers for the liquid channel and the air channel are arranged in a carrier plate, each containing filter elements.
  • the device has the disadvantage of complicated manufacture and handling.
  • DE 4010202 AI describes an extraction spike which has an extraction channel and an air channel for pressure equalization.
  • the air duct is connected to the atmosphere by an air filter on the side.
  • the removal spike is provided with a cone for attaching a syringe, for example, and a Luer lock attachment for holding the syringe.
  • This removal spike has the disadvantage that the removal material can only be removed unfiltered. This means a risk of infection for the patient, since any particles and germs are not filtered out.
  • the invention is based on the object of specifying a removal device for the sterile removal of liquids from a container of the type mentioned at the outset which, with little technical effort, ensures flow-efficient filtering of the removed liquid and a compact and material-saving design.
  • the essence of the invention consists in that a liquid filter with an angle ⁇ to the longitudinal axis of the channel is arranged in the channel in the piercing mandrel through which the liquid to be removed flows.
  • the angle is in the range between 3 to 10 degrees, preferably 6 degrees.
  • a favorable flow rate is thus achieved and there are no dead water areas in the filter chamber in which vortices can form.
  • pressure equalization between the atmosphere and the interior of the container is ensured via an air duct with an air filter in the spike during the removal of the liquid.
  • an extraction cone is advantageously provided, in which, for example, a syringe cone engages.
  • a luer lock attachment known per se can advantageously be provided coaxially with the removal cone.
  • the Luer lock approach is advantageously arranged coaxially with the removal cone.
  • the protective sleeve has openings around the Luer lock attachment through which liquid can escape if necessary.
  • FIG. 1 shows a container with the liquid to be removed and an attached removal spike according to the invention in section.
  • FIG. 2 shows an enlarged section from FIG. 1 in the area of the filter chamber.
  • FIG. 3a shows an enlarged section from FIG. 1 in the region of the removal cone.
  • FIG. 3b shows an enlarged section from FIG. 1 in the area of the Luer lock attachment.
  • FIG. 1 shows the exemplary removal device for the liquid transport from a container 4 (bottle, bag, Blasco) to a removal cone 5, from which the liquid can be removed using a syringe (not shown) or an infusion device (also not shown).
  • a corresponding syringe attachment 18 is indicated in FIGS. 3a and 3b.
  • the removal device essentially consists of a piercing mandrel 1 with a channel 6, a filter chamber 7 and a liquid filter 8.
  • the liquid flows through the channel 6 into a first half of the filter chamber 7, flows through the liquid filter 8, passes into a second half of the filter chamber 8 and finally flows into the removal cone 5.
  • the liquid filter 8 in the filter chamber 7 is opposite the longitudinal axis of the channel 6 arranged at an angle.
  • the inclination of the angle is 6 degrees in the exemplary embodiment.
  • This relatively slight inclination of the liquid filter 8 has the advantage over horizontally or vertically installed filters that the flow undergoes almost no redirection and thus no stagnation and vortex areas, also known as so-called dead water areas, occur in which suspended particles can be deposited.
  • FIG. 2 shows an enlarged section from FIG. 1 with direction lines which indicate the direction of flow of the liquid removed. It is obvious that the liquid flows through the filter chamber 7 relatively freely without the formation of dead water areas.
  • filtered air flows into the container 4 in a known manner via an air filter 10 known per se and an air duct 11.
  • Removal device here combined with a cover of the filter chamber 7, a handle plate 2 arranged, which is provided with superimposed transverse ribs. The user can put his thumb on the grip plate 2 and thus has a good grip when
  • a known Luer lock attachment 12 is arranged coaxially with the removal cone 5. This ensures an exact coupling of the removal device with the respective attachment devices, e.g. guaranteed a syringe.
  • the Luer lock attachment 12 is surrounded by a rubber-elastic protective dome 13.
  • a cover cap 3 is provided in the example, which is connected to the protective dome 13 via an elastic web 16.
  • the cover cap 3 has a peripheral edge 14 and a truncated cone 15.
  • This cover cap 3, in combination with the protective dome 13, advantageously enables the entire combination of Luer lock attachment 12 and removal cone 5 to be covered.
  • the truncated cone 15 engages sealingly in the removal cone 5 and the peripheral edge 14 simultaneously overlaps the Luer lock attachment 12.
  • openings 17 are provided all around, which enable any liquids that may occur to be drained and thus prevent increased bacterial growth in a moist chamber. This minimizes possible bacterial contamination.
  • a syringe cone 18 is inserted into the removal cone 5 of the removal device.
  • Protection dome 13 is relaxed at this time. If a lock 19 of the Luer lock attachment 12 is used, the rubber-elastic protective dome 13 is deformed and releases the Luer lock attachment 12 of the removal device. After the liquid has been withdrawn and the Luer lock attachment 12 has been unlocked, the relaxed state according to FIG. 1 is automatically restored. The Luer lock attachment 12 and the removal cone 5 are protected against contamination from the outside. To further protect the removal device, the cover cap 3 is closed manually.

Abstract

L'invention concerne un dispositif de prélèvement destiné au prélèvement stérile d'un liquide dans un récipient, en particulier dans des récipients médicaux. Ce dispositif est composé d'une aiguille comportant un canal d'écoulement du liquide, et d'un filtre à liquide destiné à filtrer le liquide prélevé. Ce filtre à liquide (8) est disposé dans le canal (6) avec un angle ( alpha ) de 3 à 10 degrés, de préférence 6 degrés, par rapport à l'axe longitudinal du canal (6). Par ailleurs, le filtre à liquide (8) est disposé dans une chambre de filtre (7) à l'intérieur du canal (6), l'axe longitudinal de cette chambre de filtre (7) étant situé sur l'axe longitudinal du canal (6).
