Definitions

  • the present invention relates to a fluid extractor, 5 particularly though not exclusively a mucus extractor.
  • a conventional mucus extractor comprises a small jar, a lid to the jar having two connections and a pair of tubes one connected to one connection and having at its free end a ° mouthpiece, the other connected to the other connection and having at its free end a nozzle for insertion into a new born baby's nostrils and/or mouth.
  • the nozzled tube is inserted into the baby's nose for instance and a midwife sucks on the mouthpiece to draw mucus from the baby's air 5 passages to assist its initial breathing. Because a midwife can be extremely busy at this stage in the baby's birth, she may omit to notice the complete filling of the jar with mucus. Then she may suck up mucus into her own mouth. Not only can this be extremely unpleasant; but also it is 0 potentially dangerous as regards infectious diseases.
  • British patent specification No: 1,273,742 describes a mucus extractor suffering from this defect. It has an inlet for mucus to a container which is oppositely directed to a suction air outlet from he container. However if the container fills to the level of the air outlet, mucus will be sucked up.
  • British patent application specification No: 2,017,497A describes a mucus extractor having an inflatable inner bag separated from an outer chamber from which suction air is withdrawn.
  • the object of the invention is to provide an improved mucus extractor.
  • an extractor comprising:- a vessel for receiving extracted fluid, the vessel being closed in use except for a fluid inlet connection for allowing fluid into the vessel and an air outlet connection for allowing withdrawal of air from the vessel; a flexible diaphragm arranged in the vessel to divide a separated space within the vessel from a fluid receiving space, flexibility of the diaphragm allowing increase in volume of the receiving space on concomitant decrease in volume of the separated space with withdrawal of air therefrom; a fluid inlet tube connected to the inlet connection for conveying fluid into the receiving space; and an air outlet tube connected to the outlet connection for withdrawal of air from the separated space.
  • the extractor may have uses other than as a mucus extractor, for instance as a lock preventing ingestion of liquid from a pipette.
  • the air outlet tube is provided with a mouthpiece, and the fluid tube is preferably provided with a nozzle.
  • the nozzle of the mucus tube In use the nozzle of the mucus tube is inserted into a baby's mouth or nose and mucus is withdrawn by suction on the mouthpiece of air tube. Suction causes deflection of the diaphragm with reduction of the volume of the separated space and increase in volume of the mucus receiving space into which mucus is drawn, since there is no appreciable pressure differential across the diaphragm. Should a midwife go on sucking after the diaphragm has moved fully to cause the separated space to be minimized and the mucus receiving space to reach a maximum volume, the mucus cannot be sucked up the air tube because the diaphragm provides permanent separation.
  • An additional unexpected advantage is that should the mucus receiving space be full with air and/or mucus and yet further mucus still need to be extracted from the baby, that in the receiver can simply be expelled by tipping the extractor and blowing into the air outlet tube and expelling the mucus via the inlet tube into a suitable receptacle. Then a further extraction operation can be effected.
  • the flexible diaphragm is adapted to at least partially invert between an initial rest position in which the separated space is at a maximum volume and an ultimate position in which the separated space is drawn down to a minimum volume, the diaphragm having at least one peipheral region at which it undergoes substantial angular deviation between its initial position and its ultimate position.
  • the extractor will be manufactured with the diaphragm in its initial rest position. Should it have become displaced prior to use, blowing into the air outlet tube will restore it to its initial position. Then the air pressure can be released prior to use to leave the diaphragm in its initial position.
  • the flexible diaphragm has two peripheral regions at which it undergoes the said substantial angular deviation and a central area bounded by one of the said regions, tthe central area being substantially flat in both the maximum and minimum volume conditions of the separated space.
  • the other of the said regions may be adjacent a fixed edge of the flexible diaphragm.
  • the diaphragm may have a generally tubular portion extending between a fixed edge and one or both of the said peripheral regions at which it undergoes the said substantial angular deviation, the peripheral regions being arranged around the tubular portion.
  • the other of the said peripheral regions (where two are provided) is at a peripheral fold in the generally tubular portion of the diaphragm.
  • the vessel is symmetric, the diaphragm peripheral being captive at the plane of symmetry.
  • the diaphragm may extend at rest in this plane of symmetry, preferably it extends out of the plane to lie close to or in contact with a sidewall of the vessel on its receiving space side, in order to maximise the usable receiving space by causing it to be a minimum prior to use and to allow the diaphragm to cross the plane of symmetry without resilient tendency to return to lie in this plane (which tendency would have to be overcome by suction on the air tube).
  • the vessel is preferably provided with ribbing internally extending from the connections to avoid suction of the membrane across the outlet connection in such a manner as to close it prior to complete evacuation of the space being evacuated.
  • the vessel has a removable, sealing lid incorporating the inlet and outlet connections, the fixed edge of the diaphragm is fixed to the removable lid and the diaphragm depends from the lid.

  • Figure 9 is a plan view of the mucus extractor of Figure 7.
  • the mucus extractor has a vessel 1 which is an assembly on a plane of symmetry 2 of two injection moulded shells 3,4.
  • the shells are of clear plastics material such as acrylic or polystyrene.
  • Each, identical, shell is of trapezoidal
  • a rim 5,6 is provided extending outwardly at the base plane.
  • a continuous groove 7,8 extending around the entire rims 5,6.
  • Each shell 3,4 has an integrally moulded connection spout 14,15 to each of which is connected a tube 16,17. With the diaphragm extending towards the shell 3 in its free position, the tube 16 becomes the mucus inlet tube and is provided at its free end with a nozzle 18 in the form of a

  • the angular deviation of the diaphragm is approximately 140°.
  • the already extracted mucus 24 can be expelled into a suitable receptacle by blowing through mouthpiece 19. A further extraction can then be carried out. At no time can mucus be drawn through the air tube 17.
  • FIG. 7 has a vessel 100 comprised of a tub 101 and a screw-top lid 102.
  • the lid has a mucus inlet connection 103 for a mucus inlet tube 104 and an air outlet connection 105 for an air outlet tube 106.
  • a diaphragm-guiding, circular cylinder 107 Depending from the lid 102 within the tub 101 is a diaphragm-guiding, circular cylinder 107 and a plurality of resilient, catch fingers 108.
  • Both lid and the tub are injection moulded of material such as polyethylene.
  • the fingers 108 are arranged circularly around the cylinder 107, outwardly of a circular bead 109 integrally moulded on the inner face of the lid.
  • a tubular diaphragm 110 is fitted over the guide cylinder 107, with a radially extending rim 111 captive by a ring 112 held by the fingers 108, see in particular Figure 8.
  • the ring 112 has a bead 113 opposite the lid bead 109, so that, when the ring is snapped into position held by the fingers, the diaphragm rim 111 is sealingly fixed to the lid.
  • the diaphragm has a tubular portion 114 extending outside the guide cylinder 107 as far as a peripheral S fold 115. Beyond this, the diaphragm extends as a further tubular portion 116 to a central bottom 117, which is substantially flat and closes the tubular portions of the diaphragm.
  • the tubular portions 114, 116 are of substantially the same length.
  • the diaphragm divides the internal space of the vessel 100 into a separated space 122 and a receiving space 123.

Abstract

Un extracteur de mucus comprend un récipient symétrique (1) comportant une connexion d'admission (14) pour un tube de mucus (16), ainsi qu'une connexion de sortie (15) pour un tube d'aspiration (17). Le diaphragme (12) est captif à sa périphérie dans un plan de symétrie. Le diaphragme (12) sépare un espace (22) à dégonfler par aspiration, d'un espace de réception (23) dans lequel du mucus est retiré par aspiration. Le diaphragme (12) a pour effet d'empêcher du mucus d'entrer dans le tube d'aspiration (17) ce qui pourrait être à la fois désagréable et dangereux.
