EMBOUCHURE POUR APPAREIL POUR TESTS DE LA TENEUR DE L'HALEINE EN
ALCOOL.MOUTHPIECE FOR APPARATUS FOR TESTING THE BREATH CONTENT
ALCOHOL.
Cette invention se rapporte à des embouchures pour appareils pour tests de la teneur de l'haleine en alcool et, en particulier mais non exclusivement, pour des appareils qui effectuent les tests en prélèvant un échantillon par une sortie latérale prévue dans le tube. Dans les appareils pour tests de la teneur de l'haleine en alcool de ce type, comme ceux fabriqués par le demandeur, l'embouchure est normalement montée sur une saillie, en forme de bulbe, de l'appareil en faisant passer la saillie à travers un trou de dimension convenable dans la paroi latérale du tube à embouchure. Le sujet souffle alors dans l'embouchure et s'il satisfait aux conditions définies par l'appareil, un petit échantillon est alors prélevé par un passage dans la saillie. This invention relates to mouthpieces for apparatus for testing the alcohol content of breath and, in particular but not exclusively, for apparatus which performs the tests by taking a sample through a lateral outlet provided in the tube. In breath alcohol testing devices of this type, such as those produced by the applicant, the mouthpiece is normally mounted on a bulbous projection of the apparatus by passing the projection to through a hole of suitable size in the side wall of the mouthpiece tube. The subject then blows into the mouth and if he meets the conditions defined by the device, a small sample is then taken by a passage in the projection.
On s'est aperçu que, dans des conditions de froid extreme ou lorsqu'un nombre très élevé de tests sont effectués immédiatement l'un après l'autre, le passage dans la saillie peut se couvrir de condensation et qu'il est possible que cette condensation compromette la lecture fournie par l'appareil. It has been found that, in conditions of extreme cold or when a very large number of tests are carried out immediately one after the other, the passage in the projection may become covered with condensation and that it is possible that this condensation compromises the reading provided by the device.
Selon l'un de ses aspects, l'invention consiste en un tube à embouchure pour appareils de tests de la teneur de l'haleine en alcool, présentant à une extrémité une entrée et à l'autre extrémité une sortie par laquelle passe la plus grande partie de l'haleine de l'utilisateur, ainsi qu'une sortie latérale de prélèvement, entre l'entrée principale et la sortie principale, la sortie de prélèvement étant définie par un tube fixé à l'embouchure. According to one of its aspects, the invention consists of a mouthpiece tube for apparatus for testing the alcohol content of breath, having at one end an inlet and at the other end an outlet through which the most large part of the user's breath, as well as a lateral sampling outlet, between the main entrance and the main outlet, the sampling outlet being defined by a tube fixed to the mouth.
Dans cette disposition,la saillie sur l'appareil disparait alors et le tube de prélèvement d'échantillon se place dans un trou de dimension convenable dans l'appareil. De préférence, le tube de sortie de prélèvement d'échantillon est dimensionné de façon à s'étendre sensiblement jusqu'à la cellule de détection de l'alcool de façon qu'une condensation éventuelle se dépose sur la paroi intérieure du tube de sortie de prélèvement. In this arrangement, the projection on the device then disappears and the sample collection tube is placed in a hole of suitable size in the device. Preferably, the sample collection outlet tube is dimensioned so as to extend substantially to the alcohol detection cell so that any condensation is deposited on the inner wall of the sample outlet tube. sample.
Bien entendu, toutes les embouchures sont jetées immédiatement après emploi dans un but hygiénique, toute condensation est éliminée de la même façon et il n'y a pas d'accumulation significative à l'intérieur de l'appareil quelles que soient les conditions extrê,es d'emploi qui peuvent intervenir. Of course, all the mouthpieces are discarded immediately after use for hygienic purposes, any condensation is eliminated in the same way and there is no significant accumulation inside the device whatever the extreme conditions, es of employment that can intervene.
Le tube à embouchure peut être prévu avec une réduction entre ses extrémités et, de préférence, le tube de sortie de prélèvement est placé près de cette réduction. The mouth tube can be provided with a reduction between its ends and, preferably, the sample outlet tube is placed near this reduction.
L'invention inclut également un appareil présentant une ouverture qui s'étend entre l'entrée de la cellule de détection de l'alcool et la surface de l'appareil pour recevoir un revêtement jeteretiotuoury pl-ac-er--un tube à-embouchure. The invention also includes an apparatus having an opening which extends between the inlet of the alcohol detection cell and the surface of the apparatus to receive a jet-ply-ac-er coating. mouth.
Bien que l'on ait défini l'invention ci-dessus, il faut comprendre qu'elle inclut toute combinaison inventive des caractéristiques présentées ci-dessus ou du texte qui suit. Although the invention has been defined above, it should be understood that it includes any inventive combination of the features presented above or of the text which follows.
L'invention peut se réaliser de différentes façons et on va maintenant décrire une réalisation spécifique à titre d'exemple en se référant aux dessins joints sur lesquels:
- la figure 1 est une vue latérale d'une embouchure conforme à l'invention montée sur un appareil associé pour tests de la teneur de l'haleine en alcool, appareil indiqué schématiquement;
- la figure 2 est une vue de dessous de l'embouchure de la figure 1; et
- la figure 3 est une section longitudinale de l'embouchure de la figure 1, depuis l'autre côté.The invention can be carried out in different ways and a specific embodiment will now be described by way of example with reference to the attached drawings in which:
- Figure 1 is a side view of a mouthpiece according to the invention mounted on an associated device for testing the alcohol content of the breath, device shown schematically;
- Figure 2 is a bottom view of the mouth of Figure 1; and
- Figure 3 is a longitudinal section of the mouth of Figure 1, from the other side.
Comme on peut le voir sur les figures, une embouchure 10 est constituée d'un tube en matériau plastique 11 qui définit une entrée 12 et une sortie 13. Entre l'entrée 12 et la sortie 13 le diamètre intérieur du tube est réduit pour former une réduction en 14 et un tube 15 de sortie pour prélèvement s'étend latéralement hors de l'embouchure à l'endroit de la réduction 14. Ce tube présente un passage intérieur 16 dans lequel on peut effectuer un prélèvement de l'haleine de l'utilisateur. Le tube de sortie pour prélèvement 15 est dimensionné pour s'étendre sensiblement jusqu'à l'entrée 17 de la cellule de détection d'alcool, à l'intérieur de l'appareil pour tests de la teneur de l'haleine en alcool 18, à la fois pour permettre d'y placer l'embouchure de façon sûre sur l'appareil 18 pour tests de la teneur de l'haleine en alcool et pour former un revêtement jetable de la sortie pour prélèvement. Les avantages de ce système ont été indiqués ci-dessus. As can be seen in the figures, a mouth 10 consists of a plastic tube 11 which defines an inlet 12 and an outlet 13. Between the inlet 12 and the outlet 13 the inside diameter of the tube is reduced to form a reduction in 14 and an outlet tube 15 for sampling extends laterally out of the mouth at the location of the reduction 14. This tube has an interior passage 16 in which it is possible to take a breath sample from the 'user. The outlet tube for sampling 15 is dimensioned to extend substantially to the inlet 17 of the alcohol detection cell, inside the apparatus for testing the alcohol content of breath 18 , both to allow the mouth to be placed there securely on the apparatus 18 for testing the alcohol content of the breath and to form a disposable coating of the outlet for sampling. The advantages of this system have been indicated above.
