Abstract
Description
- 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 is shown in FIG. 1, it 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. However, the connecting structure using aeration needle and an aseptic bottle (or the vacant glass bottle) may cause medication solution to be infected during dispensing process if the operation could not be controlled effectively. Thus, the conventional medication dispensing device fills through aeration needle and filter is highly liable to bacteria affection from outside air.
- A conventional structure is disclosed in
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. Moreover, theU.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. - To overcome the shortcomings, 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.
- In order to achieve the object set forth, 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. In operation, 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 indicates a conventional medication dispensing device;
- FIG.. 2 illustrates an improved medication dispensing device in accordance with the present invention;
- FIG.. 3 illustrates a dispensing needle in accordance with the present invention;
- FIG.. 4 is a cross-section view of a dispensing needle in accordance with the present invention.
- The detailed structure and applied theorem, function, effect can be comprehensible with reference to the following drawings.
- FIG.. 1 illustrates a conventional medication dispensing device with shortcomings as known as fore mentioned.
- With reference to FIG.. 2 and in comparison with FIG.. 3 and 4, 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, atransport pipeline 2, a perfusion device 3, afilter 4, and a dispensingneedle 5, wherein theapyrexia receptacle 1 is connected to the perfusion device 3 with thetransport pipeline 2, and the other end of the perfusion device 3 is connected to thefilter 4, and thefilter 4 is connected to the dispensingneedle 5 puncturing therubber plug 61 into the aseptic bottle. - The fore mentioned dispensing
needle 5 is designed in a thin tubular shape with anaxial groove 51 rendered at outer portion of middle section of the dispensingneedle 5, which can be wrapped around resiliently and tightly by therubber plug 61 forming a pressurization effect, and therubber plug 61 will form aloose seal part 62 at thegroove 51 portion while puncturing into theaseptic 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 theaseptic bottle 6 through the dispensingneedle 5. After the pressure being gradually accumulated in theaseptic bottle 6, it will push theloose seal part 62 to become deformed in eversion, discharge redundant air, and release pressure to reach a pressure balance. Therefore, theaseptic bottle 6 is ensured free from pollution while the process of medication dispensing being accomplished smoothly. - It could be known through above that 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.
- Although the present invention has been described with reference to a preferred embodiment thereof, it is apparent to those skilled in the art that there are a variety of modifications and changes that may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
