Description

200829213 厶J厶JA pil IX. Description of the Invention: [Technical Field of the Invention] The present invention generally relates to a breath alcohol measuring device and other breath measuring devices and discloses exhaling by using the shape elements of the portable handheld device New methods and new instruments for collection and measurement, and, in one embodiment, a breath analysis system including a portable dual inlet, self-emptying air-stable illuminating expiratory collection tube. [Prior Art] 呼 Breath collection and exhalation analysis are extremely important tools, for example, in the fight against other inappropriate behaviors of drunk driving and drunken people. Being able to measure exhalation in an efficient manner is extremely important in reducing the excessive use of alcohol. To be most effective, the breath alcohol measuring device must be portable, readily available, accurate, hygienic and inconspicuous in use and storage. The most common breath alcohol measuring devices are divided into two categories: the first type is "open flow", in which exhalation is blown to the breath detection unit without touching the lips or mouth; the second type is "closed flow". The user's mouth or lips are in contact with a tube or mouthpiece that is connected to the expiratory test unit. On the one hand, the advantage of the open flow device is that the subsequent user does not have to face the dilemma of cleaning or replacing the mouthpiece. However, conventional open-flow devices position the sensor behind the protective frame, exposing the sensor to ambient air, thereby subjecting the sensor to varying amounts of disturbing exhalation. Unfortunately, these typical open-flow devices do not stabilize the expiratory flow until the sensor performs a breath alcohol analysis. In the case where the sensor is exposed to varying amounts of expiratory volume, it is not possible to calibrate the sensor precisely, which results in inaccurate measurements. 200829213 2325lpit Ο

On the other hand, closed-flow devices typically use tubes or long mouthpieces to stabilize and/or monitor the expiratory flow, and have, for example, a disposable blow port after use or a freely disposable after use on the mouthpiece. Protect the cover to provide hygienic equipment. Closed flow devices available from Lifeloc Technologies, Inc. have detachable tubes and are used by professional law enforcers for initial screening. Because closed-flow devices are capable of stabilizing and monitoring exhalation prior to sensor detection, closed-flow devices typically have more accuracy than open-flow cells. Unfortunately, because closed-flow equipment requires frequent cleaning or replacement of parts, it is less practical. Other exhalation collection devices known in the prior art have only one expiratory collection aperture and are therefore not capable of venting ambient air and/or maintaining an old exhalation. The present invention differs from the related art in that the various disclosed modes include a unique self-emptying exhalation collection tube for exhaling into the expiratory collection tube without the mouth or mouth contacting the tube. The various types of real money also include a dual population collection tube so that the user can conveniently manage it in any factory. Since the user-in-the-air and/or old air is blown out by the user, the public features make the unit self-emptying. ^ The breath analysis system that has been opened again can be used in the open flow mode. However, ^ before the internal sensor is passed through the exhalation collection tube, so that the exhalation is %疋, ^ the measurement result is still very precise. The open expiratory split, the Tongkeli community has been installed in the device. Feng = installed along the length or width of the handheld device. For example, the public, smashing method and instrumentation can be combined with a dedicated hand-held alcohol detection device 200829213, such as a portable telephone (for example, a cellular portable radio into the Japanese city (eg, iP〇ds®), personal digital assistant (PDA), system (GPS) unit, car key holder, baton, flashlight = length and width of handheld devices such as telephone units, to add venting features and Breathing stability features to accommodate the need for breath detection.

U.S. Patent Application No. 20050053523 to the disclosure of the entire disclosure of the disclosure of the entire disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the disclosure of the disclosure of The flow is stabilized or monitored for rupture. Brooke's application also did not reveal a way to exhaust the gas and the gas from the exhalation detection section of the unit. Bfooke's application only shows an alcoholic sensory person behind the shelf. Such designs result in inaccurate detection due to exposure of the Brooke sensor to varying expiratory pressure and ambient air and/or previous exhalation by prior users.

Mumick's patent 5,361 J72 discusses the benefits of removing ambient air from the expiratory collection device and discloses a single-port, single-purpose exhalation collection tube. The Miimick exhalation collection tube has two open ends in which ambient air is forced out of the opposite end of the tube when the user exhales to a designated end of the tube to vent ambient air. Unfortunately, the Murnick collection tube only captures the exhaled expiratory flow and requires a separate detection device to analyze the user's exhalation. Because of the need for a separate collection tube to capture and store each breath sample, the Murnick collection tube only seals the expiratory sample and is not suitable for use in this field of 200829213 232Mpir.

A portable breath alcohol test is disclosed in Wolf's patent 4,744,953, in which the mouthpiece acts as a whistle to monitor the expiratory flow. The w〇lf whistle allows the user to adjust the exhalation input by listening to the sound of the mouth. W〇lf's mouth drink is a closed-flow device, and the user is required to place his lips on the tubular mouthpiece, which is not conducive to the device's shouting. The sound produced by the W〇if whistle cannot be used discreetly and cannot be used in noisy environments or by people with hearing impairments. SUMMARY OF THE INVENTION It is an object of the present invention to provide a material and _ for the detection of exhaled alcohol and other respiratory components, which have a high quasi-hoc, a joint angle f, a weekly and a (10) combination, a type of dedicated unit or Hand = =,, to cellular portable wireless, ip, raw

The beer can be used with handheld devices such as cellular portable radiotelephones: the manifold can be placed to unambiguously add more accurate breath detection, or width and exhalation stabilization features. EQUIVALENT DISCHARGE CHARACTERISTICS In one embodiment, a dual inlet, self-draining, illuminating breath collection method and apparatus provide accurate gas stabilization for lip or mouth contact. The related art requires the use of a mouthpiece to shape without the need for flow. Such mouthpieces require an air odor or replacement after each use, and 200829213 is not useful for use among people in social contexts such as groups where alcohol consumption often occurs. The sensor receives a varying amount of exhalation in the event that the user only blows directly on the sensor or on a sensor placed behind the shelf. Techniques that do not require lip or mouth contact do not provide accurate results. Port In one embodiment, the dual inlet expiratory collection tube is joined from one end of the hand piece to the other end. With the dimensions of the handpiece itself, the disclosed dual inlet collection tube can be used without increasing the volume or size of the handpiece. The monthly/double inlet exhalation collection tube is open at both ends, so that the ambient air and out, which ensure the ambient air and the previous hand to remove the smugglers. The collection tube provides an exhalation pressure and expiratory volume to the exhaled exhalation sensor, making it a dry, unpleasant smell or other substance in the exhalation. The dual inlet feature of the breath collection tube is in the prior art B for alcohol testing by multiple users. The exhalation is divided into D and the delay required for cleaning or mouthpiece replacement is from -2: in the absence of another user. Subsequent users may exhale to the collection tube end that is opposite the delivery of the former to the collection tube end, or if necessary, to use the same collection tube end as the previous user. Because of the; 5 丄 exhalable to the need to be rotated after the usual one-to-one exchange = the ability of the knife-out system to exhale at either end allows it to be collected by multiple uses = in one embodiment, Provide delivery exhalation Xuan Xuan 1, use 9 200829213 to use ^. The exhalation analysis line is transferred to the lower-collecting tube end from the turn. The transmitter presents a slower handle in the middle that has not been blown by the front-user = a new method of the system makes it possible to analyze the system's beer: the dog visually monitors the exhalation

See the supplementary measures so that the user can meet the performance criteria selected by the manufacturer or set by the manufacturer. A user wishing to increase the accuracy of exhalation may prefer to adjust the breath analysis system to require a greater amount of exhalation. One of ordinary skill in the art will recognize that a greater amount of expiratory volume will result in a greater amount, such as a mechanical amount, for example, which may result in a more __ towel measurement. The disclosed breath analysis system will have one or more sensings. The device is positioned within the middle of the beer collection tube or positioned in the sensor air passage connected to the receiver. The sensor is placed internally to solve the related problems in the related art, which is not possible for the Muraick collection tube. Unlike the Murnick collection tube, the disclosed breath analysis system uses a collection tube to vent air, stabilize exhaled breath samples, and obtain accurate and rapid expiratory component analysis. The disclosed breath analysis system can be delivered from the user to the user and I need lip or mouth contact. Unlike the Mumick collection tube, the disclosed 'exhalation analysis system provides an exhaled (d) analysis without the need for a separate instrument to empty the collection tube. In contrast to the Murnick collection tube, the tube can be combined with a dual inlet expiratory collection tube in the disclosed breath analysis system and expired f 'on-site measurement with exhalation components. Blow in and exhale. The disclosed breath analysis system overcomes the deficiencies of the Wolf whistle by enabling the user to monitor the expiratory flow in a thoughtful manner without the need for mouth or mouth contact. The user of the disclosed breath analysis system can view light at the periphery of either end of the expiratory collection tube. The light informs the user if the barometric pressure and/or expiratory volume is appropriate and the test result can be reported. The lighting features also provide a visual target for the user. Unlike Wolf mouth feeding, the disclosed system can be used without cleaning and in the dark, in the mouth and in a quiet background. Other objects of the present invention will be apparent to those skilled in the art from the following description and the appended drawings. The above and other objects, features and advantages of the present invention will become more <RTIgt; [Embodiment] Referring to the drawings of one of the plurality of illustrated embodiments of the present invention, Fig. 1 shows an exhalation analysis system 1 for air stabilization including a double inlet of the expiratory collection tube 2 and self-emptying. The total length of the collection tube 2 is approximately 5 cm. Both ends 6 of the collection tube 2 are suitable for the expiratory inlet. Thus, the user can blow either end 6 from a distance as far as his lips or mouth are not in contact with the collection tube as shown in Figure 1, and ambient air and/or old exhalation will be expelled through the opposite end. Figure 1 shows an expiratory collection tube 2 connected to a sensor device 4 comprising a sensor air channel 5.
