Definitions

  • the invention relates to a metering pipette for a medium, such as. As a liquid, a gel or the like, according to the features of the preamble of claim 1.
  • Such metering pipettes are known. They have a sleeve which forms a space for receiving a medium to be dispensed in the sleeve is a longitudinally displaceable plunger (also referred to as piston) arranged, which seals the space for receiving the medium at one end of the sleeve. At the opposite end, a discharge opening is centrally disposed in the longitudinal axis of the sleeve, through which the medium is discharged when the plunger is moved into the sleeve.
  • Such dosing pipettes are colloquially referred to as syringes or dosing.
  • At least one discharge opening for the medium located in the sleeve is arranged deviating from the longitudinal axis of the sleeve and the longitudinal movement of the plunger in the sleeve.
  • the sleeve no longer has, as known in the prior art, a central, forwardly directed opening for dispensing the medium, but that at least one dispensing opening is aligned differently from the longitudinal axis of the sleeve and the direction of movement of the plunger.
  • the at least one discharge opening is arranged approximately transversely to the direction of movement of the plunger in an end region, in particular in a front end region of the sleeve.
  • one end face of the sleeve is completely closed and the at least one discharge opening is arranged directly adjacent to the end face. This means that the end face of the sleeve is closed and no longer has a central discharge opening. Behind the region of the end face of the sleeve, which faces away from the plunger, at least one discharge opening for dispensing the medium is present. As a result, the dosing pipette can be introduced into the region in which the medium is to be dispensed from the sleeve such that the at least one dispensing opening also reaches areas which are otherwise not easily accessible.
  • the sheath can be inserted into the mouth of a patient and the throat accessed so that the medium can be delivered (administered) laterally from the sheath by pushing the plunger.
  • the dosing pipette according to the invention not only areas can be achieved for the administration, which are otherwise not readily accessible, but that advantageously a gentle and not perceived by the patient as unpleasant administration can be done.
  • at least two discharge openings are arranged in the front region of the sleeve.
  • the medium is no longer directly into the throat, but in the direction of the cheeks, more precisely in the direction of the cheek inside, injected, so that ingestion, nausea or the like is effectively avoided.
  • the medium to be dispensed is diffusely distributed orally and can be distributed in a targeted manner by the person in the mouth after dispensing and absorbed by swallowing.
  • the front region is to be understood as the region which forms half of the longitudinal extent of the sleeve starting from the end face.
  • the at least two discharge openings are arranged directly adjacent to the front side in the front region of the sleeve. Also, this is achieved with a larger discharge volume (compared to a single discharge opening) the advantage that areas are reached that are otherwise not readily accessible.
  • the at least two discharge openings are arranged symmetrically (around the longitudinal axis of the sleeve) in the sleeve.
  • the geometry of the sleeve according to the invention is preferably ergonomically half-round shaped, wherein in particular a round side of the sleeve in use surrounds the upper lip of the patient, whereas the straight bottom rests on the lower lip. Alternatively, a uniformly oval or round sleeve is conceivable.
  • the dosing pipette according to the invention is preferably used for the oral administration of media, in particular medicaments, in human patients. However, these types of dosing pipettes can also be used in the field of veterinary medicine and in the field of dietary supplements.
  • the sleeve and the plunger can advantageously consist of a plastic material, since this hygiene and, if necessary, sterility are very well realized. However, depending on the field of application, other materials can also be used. If these two parts of the dosing pipette are made of plastic, they are produced, for example, in a spraying or injection molding process, which makes it possible to realize large quantities at low cost. This is important if the dosing pipette is a disposable item that may only be used once, especially for hygiene reasons. Dosing pipettes are often used as an alternative to single use usually not only once, but for the duration of a treatment cycle. Dosing pipettes can also be washed if necessary (also in the dishwasher) and reused.
  • the sleeve of the dosing pipettes according to the invention are preferably but not exclusively made of polypropylene (PP) or polyethylene (PE).
  • the pistons are preferably but not exclusively made of polypropylene (PP) or polystyrene (PS). All materials used may or may not have a Food Grade or Pharma Grade certificate and should ideally be installed only in Class 8, 7, 6 or 5 grade cleanrooms and ideally only in accordance with ISO 17358 and ISO 13485 certified manufacturers are produced.
  • the metering pipette according to the invention may, but need not have a round cylindrical shape of the sleeve, but also oval or rectangular and ergonomic semicircular forms of the sleeve can be applied.
  • the at least one, preferably the two lateral outlet openings are aligned obliquely backwards into the palate. Alternatively, almost or completely horizontal openings can be used.
  • the dosing pipette is assembled after the production of its sleeve and its plunger, wherein the interior of the sleeve can be filled with the medium to be dispensed.
  • the one end of the plunger seals off the interior of the sleeve, wherein the at least one discharge opening is present at the opposite end of the sleeve, but initially closed. Only when the plunger is moved into the sleeve (pressed), the closure of the at least one discharge opening opens and the medium can be dispensed.
  • the dosing pipette after production has an empty interior of the sleeve, which is filled by a user of the dosing pipette (once or several times, complete or only partial filling).
  • the sleeve is immersed with its end face in a container which contains the later to be dispensed medium so that upon withdrawal of the plunger, which was initially completely disposed in the sleeve, creates a negative pressure and the medium from the container in the interior of the sleeve is sucked.
  • This process can be assisted by the fact that when the medium is aspirated from the container, for example a bottle, the dosing pipette is inserted into an inner opening of a reduction ring (also as a reduction plug, for example made of PE), wherein the outer contour of this ring into the inner contour is used in the bottle shark.
  • This reduction ring is made for example of an elastically deformable material. It can consist of solid material, it being alternatively conceivable that it has a hollow chamber, so that the inner geometry of the container (for example, the inner geometry of the bottle neck) of the outer geometry of the dosing pipette can be adapted in the region of its end face for the purpose of suction of the medium.
  • a metering pipette 1 according to the invention is shown.
  • Figure 1 shows a sleeve 2 with a receiving space for a medium, wherein in the one end portion of the sleeve 2, a plunger 3 is partially inserted with its one end.
  • the sleeve 2 has at least one, preferably exactly two discharge openings 4, via which the medium in the sleeve
  • the at least one discharge opening 4 in the foremost region of the sleeve 2 (directly adjacent to an end face 5 of the sleeve 2) is arranged in order to accommodate the largest possible volume of the medium in the sleeve 2 can.
  • Reference numeral 6 designates a direction of movement of the plunger 3 when it is moved into the sleeve 2 (pressed).
  • Figure 2 shows a detailed view of the front end of the sleeve 2, after the plunger
  • FIG. 3 shows the advantageous effect of the embodiment of the dosing pipette 1 according to the invention. It can be seen that the end of the sleeve 2 with the at least one discharge opening 4 is introduced into the mouth. For better clarity, the tongue and the teeth lying around it are shown in principle. By the arrows (delivery direction 7) is indicated that the medium from the sleeve 2 is laterally discharged via the at least one discharge opening (here two discharge openings 4) in the direction of the cheeks, so that it can not get directly into the throat.
  • the dosing pipette 1 is shown again in different views.
  • the metering pipette is shown, in which the plunger 3 occupies different positions within the sleeve 2.
  • the plunger 3 protrudes completely from the sleeve 2, so that the interior of the sleeve 2 is filled with the medium to be dispensed.
  • the two other superimposed representations show that the plunger 3 was gradually introduced into the sleeve 2 to deliver the medium from the interior of the sleeve 2 via the at least one discharge opening 4.
  • the corresponding corresponding representations are also shown in FIG. 4 on the far left again from another view of the dosing pipette 1.
  • the end face 5 of the sleeve 2 is shown. It can be seen that at least one discharge opening 4, here exactly two opposite discharge openings 4, are present.
  • the front side 5 and thus the cross section of the sleeve 2 is so semicircular and thus ergonomically designed that a straight edge 8 is present and then adjoins an arcuate, preferably semicircular edge 9 at the ends of the straight edge 8.
  • This geometry is exemplary and can of course be modified.
