Definitions

  • the present invention relates to a nasal aspiration syringe, specifically intended to extract the mucus of babies, without the need for direct contact between the baby and the person who performs the extraction of the mucus.
  • the object of the invention is to carry out a controlled extraction of the mucus of the babies, as well as to avoid aggressive efforts that could damage the baby itself and even prevent microbes from being transferred directly, since there is no direct contact between the person who performs the mucus and baby extraction.
  • the nasal aspiration syringe that has been recommended has been conceived to solve the problem described above, based on a simple but highly effective solution. More specifically, the syringe of the invention, being constituted from a hollow body and an internal and movable piston, has the peculiarity that a cannula is fitted on the front end of the body and tightly fitted with a conical end section , with a configuration that can be introduced into the baby's nose without damage to the baby, a cannula that has a hole at the end of the mucus that is intended to be removed from the baby's nose.
  • a foam block is fitted tightly, which is retained against longitudinal stops established for this purpose inside the cannula, stops that are materialized by ribs provided in the direction of the generatrix.
  • Said cannula externally has an annular projection as a stop for maximum penetration thereof inside the syringe body.
  • the piston has a head with a rhombic profile but with very rounded vertices, so that that rhombic head has a determinant posterior extension of a cylindrical neck that joins a trunk-conical section corresponding to the anterior part of the plunger itself , and whose trunk-conical section is affected by slots for the passage of air through the piston itself, during the operation of introducing it axially over the body of the syringe.
  • a gasket with a perimetral adjustment lip is mounted on the inner surface of the syringe body, and whose gasket has a maximum penetration stop in the body of the syringe when it presents an internal circumferential wall through which it is possible to pass the head of the plunger but not the seal.
  • the suctioning will be carried out by fractioning backwards of the plunger, carrying out the extraction of the mucus of the baby, establishing the vacuum by the hermetic adjustment made by the joint on the lateral surface of the body of the syringe, also allowing, once the piston is retracted, to return to the operative position by forward movement thereof, so that the air, as already said, will leave through the openings or grooves of the trunk-conical section of such plunger .
  • the backward movement of the piston with respect to the syringe body is limited by an internal annular ring corresponding to the most posterior section of the syringe body.
  • the cannula will preferably be transparent in color and in a suitable material, such as PP randon with thermoplastic elastomer mixture.
  • the foam block which will act as a stop to prevent the extracted mucus from penetrating the cannula, will be made of polyester, preferably in white, just like the plunger, while the body of the syringe will be translucent and of a material similar to the cannula, without discarding any other appropriate type.
  • Figure 1 shows a representation in general perspective of the different components that participate in the constitution of the nasal aspiration syringe object of the invention.
  • Figure 2.- Shows a sectional view of the assembly and coupling with each other of the different components represented in the previous figure.
  • Figure 3. Shows an enlarged and sectional detail of the area or part corresponding to the syringe where the head of the plunger is located with the gasket and the coupling end of the cannula on the body of the syringe.
  • the syringe of the invention comprises a hollow body (1), a cannula (2) and a plunger (3), as main components, and which are complemented by a foam block (4) and a board (5) whose functionality will be exposed later.
  • the body (1) will preferably be translucent and internally and inferiorly presenting a ring (6) as a stop element for maximum extraction of the piston itself (3), while in proximity to the front end said body (1) of the syringe includes a wall or diametral partition (7) as a nerve that acts as a stop that limits the forward movement of the joint (5), having at its base an annular nerve (8) for tight fit on the wall or internal surface of the own wall of the body (1) of the syringe.
  • the foam block (4) is arranged inside the cannula (2) and is retained as a consequence of longitudinal ribs (9) provided on the inner face of the cannula itself (2), preventing said foam block (4) can move towards the end (10) where the corresponding orifice of the cannula itself (2) is established, preferably presenting a conical configuration at said end for adaptation to the baby's nostril in which apply
  • Such cannula (2) also has an annular and external projection (11) as a limit stop for maximum penetration on the body (1) of the syringe, since such cannula (2) is coupled on such a body of the pressure syringe , on the open and upper end, ie front, of said body (1).
  • the function of the foam block (4) is to retain the mucus removed and not pass to the rest of the components, constituting a disposable element, so that once used it must be replaced by a new one, maintaining the body of the syringe with its plunger (3) and the seal itself (5), which can be washed with water as is traditional.
  • the seal (5) with its lip (8) is intended to produce the seal in the movements of the piston (3), to carry out the correct suction.
  • the piston (3) includes a head (12) with a rhombic configuration but with sharply rounded vertices, whose head joins the body of the plunger (3) through a cylindrical neck (13), and whose union it is carried out on a trunk-conical section (14) that is part of the front end of the plunger itself (3), as clearly seen in Figure 3, so that in correspondence with that trunk-conical section (14) They have provided grooves (15) for the exit of the air to the outside.

Abstract

Selon l'invention, une seringue d'aspiration nasale comprend un corps cylindrique et creux ouvert au niveau de ses deux extrémités, et un piston mobile axialement. Sur l'extrémité antérieure et ouverte, vient s'accoupler par pression, de manière démontable et jetable, une canule présentant un orifice d'extrémité pour le passage des mucosités suite au déplacement vers l'arrière du piston. A l'intérieur de la canule, se trouve un bloc de mousse, alors qu'après une cloison diamétrale interne du corps de la seringue, est monté un joint d'étanchéité situé dans un col ou un tronçon cylindrique appartenant au piston même, ledit tronçon se trouvant entre la tête d'extrémité du piston, avec une configuration en losange aux sommets arrondis au plus prêt, et un tronçon tronconique en tant que partie avant du piston, ce tronçon tronconique étant pourvu de rainures pour permettre le passage et l'évaporation de l'air lorsque le piston avance. La canule présente un tronçon avant tronconique et une configuration appropriée pour permettre son adaptation à l'intérieur de la fosse nasale. Elle comprend dans sa partie interne des nervures servant de butoir à déplacement maximal, et également dans sa partie externe une protubérance annulaire de butoir. Le joint comprend une lèvre inférieure de réglage et d'étanchéité et peut être déplacé vers l'avant et l'arrière, retenu par le piston. L'extrémité postérieure du corps de la seringue comprend un anneau interne servant de butoir de limitation de l'extraction maximale du piston lors de son déplacement vers l'arrière.
