Definitions

  • the invention relates to an aspiration device for the withdrawing of bodily fluids from body cavities and/or skin complaints and/or boils and cysts.
  • the object of the present invention is to provide for a method and a means for aspiration of bodily fluids, lying in boils or cysts just below the skin surface, in a less invasive manner.
  • the invention provides an aspiration device for the aspiration of bodily fluids on or just beneath the skin surface, employing a technique that does not require an anaesthetic.
  • the invention provides an aspiration device which includes a barrel, a plunger which sealing engages with an inside of the barrel to reciprocally move therein, a holed sealing cap which is elastically deformable and which is attached to a first end of the barrel and a penetrating element which is engaged with a first end of the plunger to pass through a hole in the sealing cap when the plunger is advanced in the barrel.
  • the plunger may include a zone of weakness at a point along its length, preferably at a point adjacent the first end. The zone may in the form of a circumferential recess or rebate formation, where the plunger may be snapped from the penetrating element.
  • the sealing cap may be brought into sealing contact with a person's skin over an area to be aspirated so that, when the plunger is advanced in the barrel, the penetrating element may pass through a hole in the sealing cap to pierce the skin, and, when the plunger is withdrawn, a partial vacuum may be formed in the barrel behind the plunger to remove bodily fluids from the area.
  • the sealing cap may be made of a suitable elastically deformable material, for example rubber or the like.
  • the sealing cap may have a truncated conical shape shaped, with an annular rim, attachable to the first end of the barrel and the hole at an apex of the cap. [0009]
  • the sealing cap may be interchangeable with another sealing cap of differing size and shape according to requirement.
  • the penetrating element may be detachably engaged to the first end of the plunger. Engagement of the penetrating element to the plunger may be effected by a fastening means, which includes a clasp, which may be located on the first end of the plunger, and a clasp engagement means, which may be located on the penetrating means.
  • a fastening means which includes a clasp, which may be located on the first end of the plunger, and a clasp engagement means, which may be located on the penetrating means.
  • the fastening means is a male-female type connector which includes a male nozzle formation on the first end of the plunger and a female formation on the end of the penetrating means.
  • the fastening means may be a bayonet type connector.
  • Figure 1 illustrates an aspiration device in accordance with the invention
  • Figure 2 illustrates, in partial longitudinal section, the device of Figure 1 ;
  • FIGS 3, 4 and 5 each illustrate a different embodiment of a nozzle of the device. DESCRIPTION OF PREFERRED EMBODIMENT
  • FIG. 1 of the accompanying drawings illustrates an aspiration device 10 in accordance with the invention which includes a barrel 12 and a plunger 14 which reciprocates within the barrel.
  • the plunger has at one end a head-piece 16 which sealing engages with the inside wall 18 of the barrel and at an opposing end a thumb-piece 20 which is shaped to receive a thumb of a user to pull the plunger outwardly and inwardly with respect to the barrel.
  • the barrel has, mounted to an upper outer side of the barrel, a finger-piece 22 which is appropriately shaped to receive two fingers of a user whilst the user's thumb is engaged with the thumb- piece 20.
  • the barrel has a forward end 24 and an opposing open end 26.
  • the plunger also includes a zone of weakness 20A at a point between the head-piece and the finger piece.
  • Figure 1 shows the zone of weakness in the form of an annular recess, which creates a point where the plunger can be snapped from the head piece.
  • a rubber sealing cap 28 which can be of any suitable shape depending on application as illustrated in 3, 4 and 5 is attached to the forward end 24 of the barrel by engaging a collar 29 of the cap to circumferentially engage the forward end.
  • the sealing cap is holed with an aperture 30.
  • an aspiration needle 34 Mounted to the head-piece, by means of an engagement means, is an aspiration needle 34.
  • the engagement means includes a male formation 32, projecting from a face 38 on the head piece, which engage with a complimentary female formation 36 in the needle.
  • the male formation fits into the female formation and, on twisting the needle in a clockwise or counter-clockwise direction, secures the needle to the head piece.
  • a first action involves a user appropriately placing his fingers and thumb into the respective finger and thumb pieces 22 and 20, pushing downwardly on the plunger so that the plunger head, with the needle 34, projecting axially towards the aperture 30, moves towards a boil or a sore on a person's skin 40 that requires aspiration.
  • the aperture 30 of the sealing cap 28 is placed over the boil or sore and the needle, at a lower limit of the headpiece, to penetrate the boil or sore as it passes through the aperture 30 allowing body fluids from the boil or sore to aspirate.
  • the user pulls on the thumb-piece 20 to move the plunger 14 within the barrel upwardly towards an open end 26. This action creates a partial vacuum within a forward cavity 44, maintained by the sealing cap 28 on the skin 40. Pressure of this partial vacuum causes the aspirated fluids to be sucked into the forward cavity and thus is removed from the boil or sore.
  • the plunger 14 is removed from the barrel and is snapped free from the penetrating element which is attached to the head-piece 16, at the narrowing 20A.
  • the head-piece and the penetrating device remain in the barrel, preventing accidental pricking by the used penetrating device. This feature prevents the reuse of a used aspiration device.
  • the bodily fluids can be discarded from the device at user's convenience.

Abstract

L'invention porte sur un dispositif d'aspiration, lequel dispositif comprend un fût, un plongeur venant en prise avec le fût et pouvant se déplacer en va-et-vient par rapport à celui-ci, un capuchon d'étanchéité attaché à une première extrémité du fût et un élément de pénétration venant en prise avec une première extrémité du plongeur, et dans lequel dispositif, lors de l'utilisation, le capuchon est amené en contact d'étanchéité avec la peau d'une personne, sur un furoncle ou un kyste, et, quand le plongeur est avancé dans le fût, l'élément de pénétration traverse un trou dans le capuchon d'étanchéité et perce la peau pour retirer un fluide corporel à partir du furoncle du kyste quand le plongeur est retiré.
