Definitions

  • the present invention pertains to a breath alcohol measuring device with a mouthpiece designed as a pressure tube with a hole for sampling breathing gas for an alcohol sensor.
  • a breath alcohol measuring device of this type has become known from DE 195 45 794 C2, in which the breathing gas flow within the mouthpiece is split into a main gas stream flowing directly to the environment and a measuring gas stream.
  • the measuring gas stream is sent through the sampling system of the device and set due to the design embodiment of the device in terms of the flow volume to a value that corresponds to that delivered by prior-art calibrating devices, so that calibration of the sampling system is possible under real flow conditions.
  • the drawback of this prior-art measuring device is the lack of hygiene and the condensation of the breathing gas stream during the direct flow of the split measuring gas stream through the sampling system.
  • the basic problem that the present invention addresses is that the mouthpiece must be changed for each test subject in breath alcohol measuring devices for hygienic reasons. This operation should be as simple and rapid as possible, because it is often necessary to test many test subjects with one measuring device in a short time, especially at night under unfavorable light conditions in the case of use by the police.
  • the mouthpiece must have a reliable connection with the measuring device during the measurement so that it will not separate during the measurement.
  • the test subject should have direct contact with the replaceable mouthpiece only during the release of the breathing gas sample and the test subject should not touch the measuring device with lips of the test subject.
  • the object of the present invention is to provide a breath alcohol measuring device that is substantially improved in terms of its handling and especially the replaceable mouthpiece.
  • the direct physical contact between the test subject being tested as well as the exhaled breathing gas sample and the breath alcohol measuring device shall be practically ruled out with the present invention.
  • a breath alcohol measuring device is provided with a mouthpiece designed as a pressure tube with a hole for sampling breathing gas for an alcohol sensor.
  • the mouthpiece has a trapezoidal cross section, which is complementary to a corresponding negative shape in the holder of the breath alcohol measuring device. This allows for a flush mounting of the mouthpiece.
  • An especially preferred embodiment of the present invention is characterized in that the trapezoidal cross section of the mouthpiece is equilateral, and the hole in the mouthpiece for breathing gas sampling is located in the shorter of the two parallel sides of the cross section of the mouthpiece.
  • Another preferred embodiment is characterized in that the mouthpiece has a stop, which extends over at least some sections circumferentially in the circumferential direction of the cross section and which sets the correct position of the mouthpiece in the longitudinal direction relative to the holder, so that the suction channel of the measuring device extends exactly through the hole of the mouthpiece for taking a breathing gas sample.
  • FIG. 1 is a schematic view of a breath alcohol measuring device according to the invention.
  • FIG. 2 is a vertical sectional view taken along the line A-B of FIG. 1.
  • FIG. 1 shows the view of a breath alcohol measuring device 7 .
  • Similar such measuring devices are available commercially especially under the trademark Alcotest®.
  • the replaceable mouthpiece 1 is inserted into the holder 6 and is made of, e.g., a plastic such as polyethylene.
  • the mouthpiece 1 has a hole 10 , through which the suction channel 8 extends into the breathing gas stream (breath stream) blown in from the left as indicated by the arrow in FIG. 1.
  • the pump 9 is actuated such that it delivers a breathing gas sample from the breathing gas stream into the measuring device and consequently into the alcohol sensor 5 by means of a sampling stroke when the test subject has blown a sufficient volume of breathing gas through the mouthpiece 1 .
  • the blow-in opening of the mouthpiece 1 is expanded in a circular pattern in order to make possible a good closure with the lips.
  • the mouthpiece 1 also has a trapezoidal cross section as can be seen in FIG. 2.
  • the trapezoidal cross section of the mouthpiece 1 is complementary to a corresponding negative shape in the holder 6 of the breath alcohol measuring device 7 .
  • the trapezoidal cross section of the mouthpiece 1 is preferably equilateral, and the hole 10 for sampling breathing gas is located in the shorter of the two parallel sides of the cross section as can be seen in FIG. 2.
  • a blow-out opening 2 with a diameter of about 4 mm to 5 mm is located at the outlet-side end of the mouthpiece 1 , which is the right-hand end in FIG. 1.
  • the breathing gas stream generates a dynamic pressure, which is detected by means of the pressure sensor 11 .
  • the measured pressure corresponds to a certain breathing gas volume flow, from which the breathing gas volume released is determined by time integration.
  • the mouthpiece 1 has the cross section described at least in the area of the holder 6 .
  • the upper parallel side (parallel to the lower side) has a length of about 9 mm.
  • the lower parallel side (parallel to the upper side) has a length of about 4 mm.
  • the height of the trapezoid is about 10 mm.
  • the holder 6 is designed as a negative shape to the shape of the mouthpiece 1 .
  • the mouthpiece can be guided securely on the three lateral surfaces that are complementary to the holder 6 and it is as a result firmly seated in the holder 6 .
  • the trapezoidal cross-sectional shape of the mouthpiece 1 facilitates the attachment to the holder 6 , so that the suction channel 8 extends through the hole 10 as desired.
  • the orientation of the mouthpiece 1 in relation to the measuring device is thus defined unambiguously.
  • an external stop 3 extending circumferentially over at least some sections is present, in particular, in the circumferential direction of the cross section of the mouthpiece 1 for the lateral position of the mouthpiece 1 in the holder 6 , so that the mouthpiece 1 fits the holder 6 in a completely fitting manner only when the suction channel 8 extends through the hole 10 .
  • the stop 3 thus defines the correct lateral position of the mouthpiece 1 in relation to the holder 6 .
  • the positioning pin 4 which is optionally present, is used, on the one hand, as an aid for the correct orientation of the mouthpiece 1 for being received in the holder 6 , especially also when the mouthpiece 1 is still packaged, e.g., in a transport film.
  • the positioning pin 4 is especially useful in the case of unfavorable light conditions during use for measurement and because the mouthpiece 1 still has to be partially packaged in the contact area for hygienic reasons during the attachment to the holder 6 by the user.
  • the positioning pin 4 acts as a spacer for the test subject, so that contact between the measuring device and the test subject's lips is prevented from occurring.
  • the mouthpiece 1 and the holder 6 are symmetrical in relation to the breath alcohol measuring device 7 , so that the mouthpiece 1 can be received in the holder 6 in two different positions differing from each other by 180°, and an additional improvement of the handling of the mouthpiece 1 is thus made possible.
