Definitions

  • the invention relates to a liquid dispenser, in particular a liquid medication dispenser, for the drop-wise dispensing of a liquid, in particular a liquid medication, in which the storage container can be closed by a deformable membrane and the liquid therein is displaced by displacement of the volume by a slight pressure on the membrane Outlet tube is dispensed, and a holder for this liquid dispenser.
  • a drop of the liquid can be removed with one hand using tweezers and a cotton ball held by them.
  • Storage container known, which can be closed by a membrane-like cover and which has a laterally beak-like protruding outlet tube, under which a small bowl is to be placed.
  • a drop of the liquid in the container is dispensed at the outlet tube, which drops into the cup and can be picked up there using tweezers and a cotton pellet.
  • the cup can be replaced and re-sterilized.
  • the disadvantage of this dispenser is the two-part structure of the storage container and Withdrawal apple; as a result, it takes up a relatively large space and, above all, does not permit one-handed operation. It must always be pressed with one finger of the one hand on the membrane-like cover of the storage container, while the other hand holds the tweezers with the cotton ball in order to take up the dispensed drop on the outlet tube or in the cup.
  • the storage container is closed by a membrane in which a fine opening is provided.
  • pressure e.g. With the tweezers, liquid is pumped from the container through the outlet opening onto the membrane and can be taken up there. Emhand actuation is possible in this case, but hygiene is not sufficiently satisfied. Since the liquid is pumped directly onto the lid closing the storage container, backflow of unused liquid in the container cannot be avoided. For hygienic reasons, this dispenser is in any case unsuitable in the medical field and wherever contamination must be avoided.
  • Dappen glasses Commercial, small glass containers with lids, so-called Dappen glasses, are also used. A one-hand dosing is not possible with it, and the tweezers must always be immersed in the liquid so that contamination is inevitable. The container can only be sterilized as a whole.
  • the object of the invention is to provide a liquid dispenser for the dropwise metering of a liquid, which allows emhand actuation and is particularly suitable as a liquid medication dispenser, ie it meets the strict requirements that are to be placed on hygiene in the medical field. Parts that come into contact with the tweezers and the cotton ball or another instrument for absorbing the liquid must be easily replaceable and sterilizable.
  • the dispenser is designed to be a compact, have a stable construction and are suitable for installation in flat drawers and several in a kind of battery for the removal of different liquids.
  • this is achieved in that the opening of the outlet tube is directed towards the surface of the replaceable membrane sealingly resting on the container opening.
  • an instrument e.g. a pair of tweezers holding a cotton ball, which exerts pressure on the membrane, at the same time also absorbs the liquid dispensed dropwise from the outlet tube; one-handed operation has been reached.
  • the cotton ball or tweezers only come into contact with the liquid dispensed on the membrane and never with the contents of the container; A backflow of unused, contaminated liquid is impossible.
  • the hygienic operation of the liquid dispenser is guaranteed.
  • the surface of the membrane is slightly curved inwards so that it forms a small collecting or removal container.
  • the membrane preferably lies on a step provided on the inner edge of the container opening and can be easily replaced before any further operation, which also serves for hygiene.
  • a step can also be cut into the underside of the membrane, with which it rests on the inner edge of the container opening or on a step provided on the inner edge of the container opening.
  • a recess on the container rim protruding radially beyond the membrane makes it easier to replace the membrane, since it can be easily gripped here, for example with tweezers.
  • a small pin can be provided on the membrane, on which it is located can be replaced with tweezers. The recess at the edge of the container can then be omitted.
  • the membrane can be provided with a small, stick-like extension or handle in order to make it easier for an assistant to replace the membrane without having to use tweezers.
  • a tubular connection is provided from the container edge protruding radially beyond the membrane into the interior of the container, into which an outlet tube directed towards the membrane is inserted.
  • a radial bore opening directly above the inner bottom into the container interior is provided in the container wall, which meets in the container wall with a vertical or almost vertical bore that extends from the container rim projecting radially beyond the membrane.
  • the outlet tube is inserted or pressed into the vertical bore, the projecting end of which is bent toward the membrane.
  • the side hole is closed to the outside by a plug or peg.
  • the tubular connection can also be integrally formed on the side of the container wall.
  • the vertical bore or the tubular connection can advantageously be divided by a step into a narrower and a further section, so that the outlet tube inserted into the further section can rest on the step. If the outer surface of the container is concavely curved, the dispenser can easily be grasped by hand and moved if necessary.
  • the contact surface of the container is preferably an annular surface, which can be achieved by a concave curvature or a central recess in the outer bottom surface.
  • the dispenser can be placed on a surface with appropriate elevations so that it is non-slip. Good stability is achieved.
  • the container can be inserted into a holding part which has an essentially cubic shape and in the top of which there is an opening for receiving the container, on the edge of which the
  • Containers can rest with a circumferential collar molded onto it.
  • the mounting parts can advantageously be connected to one another to form a type of battery by means of connecting means molded onto their side surfaces.
  • These connecting means can be designed as tongue and groove connections.
  • Dovetail-shaped recesses are preferably formed on two side surfaces of each holding part that are opposite one another and dovetail-shaped extensions (springs) that fit into the recesses (grooves) on the two side surfaces that are opposite one another in the other direction.
  • a pin-shaped extension which fits into a corresponding recess on the container collar, can be formed on the upper side of each holding part in the bearing region of the container collar. In this way, the liquid dispenser can be secured in the holder against twisting.
  • the membrane and / or the outlet tube and / or the container itself can be colored according to a color code which indicates the content of the container; this is particularly advantageous if several of the liquid dispensers according to the invention with different contents are arranged to form a type of battery.
  • the container and the outlet tube are preferably made of a non-corrosive material. If the container is made of chromium-nickel steel, it can advantageously be produced as a turned part. However, it can also be advantageously molded from plastic.
  • Silicone gum i is particularly suitable as the material for the membrane; however, it can also consist of a plastic, such as polystyrene. In the latter case, a sealing ring is expediently arranged between the membrane and a step of the inner edge of the container.
  • the membrane can be designed as a disposable part for single use.
  • FIG. 1 is a perspective view of a liquid dispenser according to the invention
  • FIG. 2 is a perspective view of a central section through the liquid dispenser according to FIG. 1,
  • Fig. 4 shows the side view of two interconnected
  • FIG. 5 is a plan view of two interconnected bracket parts shown in FIG. 4 without a liquid dispenser.
  • the liquid dispenser 1 consists of a substantially cylindrical or cup-shaped, upwardly open container 2.
  • a replaceable membrane 3 sealing against the edge is inserted into the opening.
  • a step 4 is preferably provided on the edge of the container opening, on which the membrane 3 can rest. If it is considered advantageous in certain applications, a step can also be cut into the underside of the membrane 3, starting from the outer edge, by means of which the membrane 3 can rest on the inner edge of the container 2 or on the step 4 provided on the inner edge of the container .
  • a small recess 6 is advantageously provided, which
  • Exchanging the membrane 3 is facilitated by easily using an instrument, e.g. a pair of tweezers.
  • the membrane can be provided with a small pin 5 (see FIG. 4), on which it can be easily gripped with tweezers; the recess 6 is then unnecessary.
  • the membrane can be provided with a small, stick-like extension or handle. This makes it possible to replace the membrane without using tweezers and e.g. easier for an assistant.
  • a tubular connection 9, 10 is provided from the container edge 11 projecting radially beyond the membrane 3 into the interior of the container.
  • a radial bore 9 can be made in the container wall 8 from the outside, which opens into the interior of the container directly above the inner bottom 7 and meets in the container wall 8 with a second, vertical or almost vertical bore 10, which extends beyond the membrane 3 protrudes radially Container edge 11 goes out.
  • the radial bore 9 is closed to the outside by a plug or peg (not shown).
  • An outlet tube 12 is pressed into the vertical bore 10, the projecting end 13 of which is bent down in the direction of the membrane 3.
  • the vertical bore 10 can advantageously be divided into a narrower and a further section by a step 14. If the outlet tube 12 is pushed or pressed into the further section from above, it can sit on the step 14 and assume a precise position.
  • the container 2 is filled with a liquid and covered by the membrane 3, light pressure on the membrane 3, e.g. with tweezers holding a cotton ball, the volume of the container interior is changed so that a small amount of the liquid is displaced upwards through the bores 9 and 10 and dropwise leaves the outlet tube 12 and thus directly on the top of the membrane 3 with the cotton ball, with which the pressure can also be exerted, absorbed or absorbed.
  • the surface of the membrane 3 is preferably curved slightly inwards, so that it forms a small collecting and removal container. One-handed operation is thus achieved.
  • the membrane 3 can be removed and replaced with a new one.
  • the membrane 3 can either be designed as a disposable part for single use or can be re-sterilized for reuse. In any case, strict hygienic requirements are met without the entire liquid dispenser having to be sterilized at short intervals.
  • the outer surface of the container 2 can have a concave curvature 17.
  • the dispenser not only gives the dispenser a pleasant appearance, it is also easy to handle and can be gripped better by hand, for example if it is to be implemented.
  • the outer bottom surface can be curved inwards centrally or have a central recess 18; an annular surface 19 remains on the ground as a contact surface, which allows the individual liquid dispenser to be placed on a surface which is correspondingly equipped with elevations in a non-slip manner. This gives it the required stability.
  • the liquid dispenser can be several in a kind of battery on a corresponding surface, e.g. in a drawer so that different liquids, e.g. Liquid medication can be kept ready and dosed. These can be distinguished by a color code, in that the membranes 3 or the outlet tubes 12 or both of the individual dispensers are colored differently in assigned colors. Especially if the liquid dispenser is made of plastic, the container itself can also be colored according to a color code.

Abstract

L'invention concerne un distributeur de liquide permettant de délivrer une dose goutte à goutte notamment de médicaments liquides. Un contenant (2) ouvert en haut peut être fermé par une membrane (3) déformable. Une légère pression exercée sur la membrane (3) permet d'extraire goutte à goutte du liquide du contenant (2) par un tube de sortie (12) conduisant de l'intérieur du contenant vers l'extérieur. L'ouverture du tube de sortie (12) est orientée vers la surface de la membrane (3). Un instrument, p.ex. une petite pince tenant un tampon d'ouate, permet simultanément d'exercer une pression sur la membrane (3) et de recueillir le liquide expulsé du contenant (2). Le distributeur peut ainsi être manipulé d'une seule main. Selon l'invention, tout reflux du liquide éventuellement non utilisé est exclu. L'instrument entre en contact uniquement avec la membrane (3) et avec le liquide délivré dessus. La membrane (3) peut être changée avant chaque nouvelle utilisation de telle façon que soient satisfaites les grandes exigences en matière d'hygiène propres au milieu médical. Les distributeurs de liquide (1) peuvent être assemblés en nombre quelconque et dans différentes directions pour former un groupe à l'aide d'un support (21) dont la face supérieure possède une ouverture (22) destinée à loger le distributeur de liquide (1) et les faces latérales présentent un élément de liaison se présentant p.ex. sous la forme d'un assemblage à rainure et languette (23, 24).
