Definitions

  • the present invention relates to an improved medication dispensing device, and particularly to a fill dispensing needle structure that can automatically discharge air pressure in the medication bottle to avoid the medication within from outside pollution.
  • a conventional medication dispensing device uses a perfusion device to transfer the prepared medication solution stored in the apyrexia receptacle by a transport pipeline through a filter to filter out particles and bacteria.
  • the medication solution is syringed into an aseptic bottle by a dispensing needle which punctures the rubber plug to produce injection medication in a bottle, and there is an aeration needle penetrating the rubber plug for pressure release to avoid pressure accumulated in the aseptic bottle during medication dispensing process.
  • the other way to produce injection medication is to syringe the medication solution directly into a vacant glass bottle, seal the bottle, and followed by high pressure disinfection.
  • the connecting structure using aeration needle and an aseptic bottle may cause medication solution to be infected during dispensing process if the operation could not be controlled effectively.
  • the conventional medication dispensing device fills through aeration needle and filter is highly liable to bacteria affection from outside air.
  • U.S. Pat. No. 4,801,047 comprises an aeration needle and a suction needle. It is used for radionuclide generator and the disadvantage is like fore mentioned that the outer and inner space are not partitioned.
  • the U.S. Pat. No.5,300,042 is also an apparatus for dispensing medication, however, it is designed for elderly or patient in hospital where an aseptic environment is not required.
  • the present invention tends to provide an improved medication dispensing device to mitigate and obviate the aforementioned problems.
  • the primary objective of the present invention is to provide an improved medication dispensing device according to claim 1.
  • An improved medication dispensing device includes an apyrexia receptacle, a transport pipeline, a perfusion device, a filter, and a dispensing needle, which operates in the environment in compliance with Class 100 laminar air ventilation.
  • the perfusion device erected at the middle of the transport pipeline which has two ends link to the apyrexia receptacle and the filter, respecitvely.
  • the perfusion device pumps the prepared medication solution from the apyrexia receptacle to get through the filter to remove particles and bacterium, and a thin tubular dispensing needle which punctures the rubber plug of an aseptic bottle.
  • An axial groove rendered in the middle section of the dispensing needle forms a loose seal part with the rubber plug resiliently wrapped around at the middle of the dispensing needle to discharge redundant air pressure accumulating in the aseptic bottle while keeps outside air from entering.
  • the other object of the present invention is to reduce the severe environmental equipment request and product cost appropriately by blocking the medication bottle from pollution.
  • FIG.. 1 illustrates a conventional medication dispensing device with shortcomings as known as fore mentioned.
  • the whole structure of the present invention relates to a medication dispensing device which operates in an environment in compliance with Class 100 laminar air ventilation, comrising an apyrexia receptacle 1, a transport pipeline 2, a perfusion device 3, a filter 4, and a dispensing needle 5, wherein the apyrexia receptacle 1 is connected to the perfusion device 3 with the transport pipeline 2, and the other end of the perfusion device 3 is connected to the filter 4, and the filter 4 is connected to the dispensing needle 5 puncturing the rubber plug 61 into the aseptic bottle.
  • the fore mentioned dispensing needle 5 is designed in a thin tubular shape with an axial groove 51 rendered at outer portion of middle section of the dispensing needle 5, which can be wrapped around resiliently and tightly by the rubber plug 61 forming a pressurization effect, and the rubber plug 61 will form a loose seal part 62 at the groove 51 portion while puncturing into the aseptic bottle 6.
  • the medication solution will be pumped by the perfusion device 3, passed through the filter 4 to filter out particles and bacterium, and then led into the aseptic bottle 6 through the dispensing needle 5. After the pressure being gradually accumulated in the aseptic bottle 6, it will push the loose seal part 62 to become deformed in eversion, discharge redundant air, and release pressure to reach a pressure balance. Therefore, the aseptic bottle 6 is ensured free from pollution while the process of medication dispensing being accomplished smoothly.
  • the improved medication dispensing device of the present invention provides an effect of discharging redundant air pressure in the aseptic bottle automatically to avoid pollution from outside.

Claims (5)

  1. Ein verbesserter Medikamentspender, der folgende Teile umfasst: einen hitzebeständigen Behälter (1), der die vorbereitete medizinische Lösung bereithält, einen Transportschlauch (2) der den hitzebeständigen Behälter (1) und den Filter (4) miteinander verbindet um die medizinische Lösung zu filtrieren;
    ein im mittleren Abschnitt des Transportschlauches eingebautes Infusionsgerät (3), um die medizinische Lösung vom hitzebeständigen Behälter zum Filter zu pumpen, welcher seinerseits folgende Teile umfasst:
    eine dünne rohrförmige Nadel (5) mit einer achsenförmigen Rille (51) am äußeren Bereich des mittleren Abschnittes der Nadel, welcher fest von dem Gummistopfen (61) umgeben ist und einen Druckeffekt erzeugt. Die achsenförmige Rille ist so geformt, dass der Gummistopfen (61) ein lockeres Siegel bildet, während die Nadel durch ihn hindurch in eine sterile Flasche (6) führt.
  2. Ein verbesserter Medikamentspender, der wie in Patentanspruch 1 einen hitzebeständigen Behälter (1), Transportschlauch (2), Infusionsgerät (3), Filter (4) und die Nadel (5) können in Übereinstimmung mit Klasse 100 laminarer Belüftung in Betrieb genommen werden.
  3. Ein verbesserter Medikamentspender wie in Patentanspruch 1 oder 2 bei dem der Filter (3) mit einem 0.22µm Film ausgestattet ist, um Partikel und Bakterien herauszufiltern.
  4. Ein verbesserter Medikamentspender wie in Patentanspruch 1 oder 2, bei dem das Material des Transportschlauches vor Abnutzung durch Säuren und Basen geschützt ist.
  5. Ein verbesserter Medikamentspender wie in Patentanspruch 3, bei dem das Material des Transportschlauches (2) vor Abnutzung durch Säuren und Basen geschützt ist.
