Definitions

  • the present invention relates to a device for mixing a fluid with a pulverized substance which has a tendency to emit dust or powder when touched by the fluid.
  • substance is intended to embrace particularly, but not exclusively, poisonous or toxic substances such as medicines, biocides or the like.
  • EP-A-0 356 480 A method of avoiding that dust whirls up against the attendants is known from EP-A-0 356 480.
  • the known method is, however, relatively complicated since it requires the use of a filter which has to be liquid as well as gas permeable.
  • the object of the invention is, therefore, to provide a device of the aforementioned kind which has a satisfactorily dust blocking function which does not require any complicated filter of the above-mentioned type, but which only requires a simple and cheap gas permeable filter, for instance of so called dry filter type.
  • the Figure shows a device according to the invention, including a container, namely a medical container in the form of a cylindrical glass bottle 1 having an externally screw-threaded cylindric neck 2, the circular opening 3 of which defines the only opening of the bottle 1.
  • the container 1 is partially filled with a predetermined amount of a pulverized medical substance 4, for instance antibiotic in the form of penicillin, for instance.
  • the container 1 is designed to be partially filled with a predetermined amount of fluid 5, for example water, that is to be mixed with the medical substance 4, for instance up to a level 6.
  • the fluid lock 9 consists of a tube 10 which is fastened in the opening 8 and oriented coaxially in relation to the neck 2 of the bottle, the upper portion 10a of the tube, which is located outside the mouth of the neck 2, being funnel shaped in order to facilitate the filling of fluid into the bottle 1.
  • the lowermost portion of the tube 10, which is inserted into the bottle 1, supports, for instance by means of threads 11 or other suitable supporting means, a circular dish 12 having a larger diameter than the tube 10 and an upwardly directed brim 13, the edge 13a of which extends a short distance above the lowermost end edge of the tube 10.
  • the function of the device is as follows: When the fluid, here water, is poured into the bottle 1 in the direction of arrow 14, some of the fluid 5 will stay on the dish 12 up to a level in registry with the edge 13a of the dish, and also at a distance up in the tube 10. This fluid on the dish 12 and up in the tube 10 thereby form a fluid lock which blocks gas, here air, from flowing out through the fluid lock from the interior of the bottle 1.
  • gas here air
  • the cap 15 is so designed that it, when screw-tightened over the neck 2, automatically destroys or deforms the fluid lock such that the patient can pour out the content without having to first remove the fluid lock.
