Definitions

  • This invention relates to face masks as used in the administration of gases during medical treatment.
  • Face masks used for the administration of anaesthetic gases generally include a tubular female connector of a relatively wide bore. This connector has a slight taper to mate with a male connector, and is therefore sometimes known as a "cone".
  • the anaesthetic gases are conducted to and from the patient via the coupled male and female connectors, the expired gases usually being diverted through a one-way valve to be ducted safely away.
  • Another form of face mask used for administration of oxygen has a tubular connector of a relatively narrow bore to which small bore flexible tubing is attached to conduct oxygen to the mask. Expired gases are allowed to dissipate from the mask directly to atmosphere via ports in the wall of the mask. These ports also allow entrainment of atmospheric air into the inspired gases to dilute the. oxygen being supplied.
  • the present invention seeks to provide a new and inventive form of face mask.
  • the present invention proposes a face mask comprising a first tubular connector through which anaesthetic gases can be supplied to the mask when used in anaesthesia, characterised by a second tubular connector of smaller diameter mounted within the first such that, alternatively, oxygen can be supplied to the mask through the second connector, at least one passage being formed between the first and second connectors to admit atmospheric air into the mask when used to supply oxygen and allow passage of expired gases to atmosphere.
  • the mask can be used for both anaesthesia and administration of oxygen the number of masks which a hospital or other user would need to stock is reduced. Furthermore, since a patient can be provided with a single mask for both purposes fewer masks need be used overall, and sterilisation costs are reduced.
  • the second connector is preferably mounted substantially co-axially within the first connector.
  • the second connector may, for example, be supported by a plurality of radial fins which join the first and second connectors.
  • the two connectors may conveniently be formed as a single moulding, thereby reducing the cost of the mask.
  • Figure 1 is a front view of a face mask in accordance with the invention
  • Figure 2 is a transverse section through the mask as used in anaesthesia
  • Figure 3 is a similar section through the same mask, used for administration of oxygen.
  • the face mask comprises a flexible plastics or rubber moulding 1 of conventional concave shape, having a single rear opening 2 for sealable contact with the face of a patient such that the mask encloses the patient's nose and mouth.
  • This portion of the mask could also be partly rigid with a flexible sealing skirt.
  • An injection moulded component 3 of generally tubular form is sealed into the opposite front wall of the mask to extend both inwardly and outwardly of the mask wall.
  • the component 3 could also be formed integrally with the moulding 1.
  • the component 3 and/or the moulding 1 could be formed of opaque or clear material.
  • the component 3 comprises a radially outer cylindrical portion 4, the internal surface of which has a small inward taper.
  • the portion 4 thus forms a first connector or cone into which a co-operating male connector or cone 5 can be inserted, as indicated by the arrow.
  • the male connector has a tapered male portion 6 which is dimensioned to engage in the female connector 4 with an interference action, thereby forming a seal between the two connectors 4 and 5.
  • the male connector 5 is coupled to a hose (not shown) in conventional manner through which anaesthetic gases are conducted to the mask.
  • the hose also conducts expired gases away from the mask via the connectors 4 and 5. It is important to note that in this use of the mask, the mask and hose are completely sealed so that the gases are unable to escape to atmosphere.
  • the component 3 further comprises a second tubular connector 8 which is mounted co-axially within the first connector 4.
  • the second connector 8 is supported from the first connector by integral radial fins 9, and an annular passage 10 is formed between the two connectors 4 and 8.
  • three or four such fins are provided, although two fins or even one fin could be used if of sufficient strength.
  • five or more fins could be used provided the passage 10 is of sufficient cross-sectional area.
  • the fins 9 are disposed at the inner end of the component 3 so that they do not impede the insertion of the male connector 5.
  • An oxygen pipe 12 is coupled to the outer end of the second connector 8, as shown in Fig. 3.
  • the pipe 12 can thus supply oxygen to the mask, which is diluted by entrainment of atmospheric air through the annular passage 10. Exhaled gases are similarly exhausted directly to atmosphere through the passage 10.
  • a single mask can be used for administration of anaesthetic gases or oxygen.
  • male and female connectors 5 and 4 could be employed, e.g. a screw coupling.
  • the inner connector 8 could be offset to one side of the outer connector 4.

Abstract

L'invention concerne un masque facial destiné à l'administration d'anesthésiques et comprenant un premier raccord tubulaire (4) par lequel le masque peut recevoir des gaz anesthésiques lorsqu'il est utilisé en anesthésie. Un deuxième raccord tubulaire (8) d'un diamètre plus réduit est monté de manière coaxiale dans le premier raccord, de sorte que de l'oxygène puisse également être introduit dans le masque à travers le deuxième raccord. Le premier raccord supporte le deuxième raccord au moyen d'ailettes radiales (9) et un passage annulaire (10) formé entre le premier et le deuxième connecteur permet d'introduire de l'air atmosphérique dans le masque lorsqu'il est utilisé comme source d'alimentation en oxygène, et d'expulser les gaz expirés, dans l'atmosphère. Les deux raccords (4, et 8) peuvent, de façon plus pratique, être moulés en une pièce unique.
