Description

Smoking tester that detects smoking with saliva {A SMOKING TEST DEVICE THAT DETECTS WITH SALIVA}

The present invention relates to a smoking tester, and relates to a tester that conveniently detects whether a subject smokes or not by saliva.

The health damage caused by smoking is very serious at home and abroad. The fact that inhaled cigarette smoke contains many environmental carcinogens has been clearly demonstrated in several epidemiological studies, and smokers are 10 times more likely to develop lung cancer than non-smokers. The harmful effects of smoking are well recognized by the general public.

Accurate identification of smoking status in studies related to smoking and smoking cessation or patient care is an issue that is receiving special attention in developed countries where health science is developed. In particular, self-report in the form of questionnaires cannot secure reliability in identifying whether or not smoking in adolescents whose physical development has not been completed. Therefore, it is important to identify and manage smoking status through a test for a specific component to determine the smoking status based on scientific grounds.

Smoking status can be measured by detecting components or metabolites of tobacco smoke in body fluids such as urine, blood, saliva, and sweat, or in hair. Biochemical indicators for determining smoking status include nicotine, cotinine, thiocyanate, and carboxyhemoglobin. Currently, a tester for detecting smoking using such a biochemical indicator is provided in the form of detecting whether or not smoking is present by a change in color reacted by applying urine or saliva to a disposable strip.

As a conventional smoking tester, there is Korean Utility Model Registration No. 20-0485459 (hereinafter abbreviated as 'prior literature'). 1 shows a smoking tester of the prior art. Referring to FIG. 1, the smoking tester of the prior literature includes an indicator for detecting cotinine, an absorbent rod 200 connected to the indicator and absorbing the subject's saliva, a case 300 for accommodating the indicator, and attached to the top of the case. It is configured to include a guide cover 400 to be.

As a smoking tester for detecting saliva, a product based on the technology of FIG. 1 is being commercialized. Figure 2 shows an exploded view of the actual product of the smoking tester patent of Figure 1. Referring to FIG. 2, the smoking tester has a minimized product configuration in which a sticker 400 is attached to an injection product of one case 300 accommodating an indicator in order to reduce manufacturing cost due to its disposable nature. Here, as shown in FIGS. 1 and 2, the conventional saliva detection-based smoking tester requires the configuration of a moisture absorbing rod 200 to deliver saliva to an indicator coated with a chemical substance for detecting cotinine.

The reason for this design is that when the absorbent rod 200 is omitted and the indicator is directly exposed, it is easily contaminated by external environmental factors, the chromatography strip is thin and small, and it is not easy for the test subject to sufficiently contact the tongue, and the contact area of the strip This is because it is disadvantageous to contain enough saliva because it is not enough. In some cases, if there is no configuration of the absorbent rod 200, if the tongue is brought into contact with the end of the strip and bitten for a period of time during which saliva components are separated, saliva overflows to the outside of the tester or excess saliva to the area around the indicator. This inflow may cause a problem that makes the result inaccurate.

Accordingly, the saliva-based smoking tester of FIGS. 1 and 2 is configured such that the moisture absorbent rod 200 is configured as a saliva transporter to contact the indicator, and a sticker-type upper cover is implemented to fix the moisture absorbent rod 200. I can understand.

However, as the conventional saliva-based smoking tester has a structure for delivering saliva called the hygroscopic rod 200, it may be convenient for the subject to hold, but after the hygroscopic rod 200 is sufficiently wet with saliva, the indicator displays the saliva Since this is transmitted, there is a problem in that the detection time for biochemical indicators of smoking becomes that much longer.

Referring to FIG. 3 , the smoking tester 1 according to the present embodiment may include a lower plate 10, a strip 20, and an upper plate 30. The smoking tester 1 according to this embodiment is largely composed of two injection moldings of a lower plate 10 and an upper plate 30.

In the smoking tester 1 according to the present embodiment, a cover 301 that opens and closes is formed on the top plate 10 to expose the strip 20. The cover 301 may be configured separately from the top plate 10, but may be formed extending from the top plate 10 and injection-manufactured together with the top plate 10. The cover 301 may be tilted up to a predetermined angle (90°).

The cover 301 according to the present embodiment is opened and closed at an acute angle (90° or less), and the cover 301 in the acute angle range detects the back of the tongue when the subject touches the tongue to the detection unit 101 to be described later. By covering it, it is possible to prevent excessively ejected saliva droplets from falling to the floor or body during the test.

When the subject directly introduces saliva by contacting the tongue to the strip 20 exposed through the cover 301, the saliva moves along the mobile phase of the strip 20 and the mixture is separated and the incision of the upper plate 30 ( 303), the presence or absence of nicotine or cotinine is read. If a line is formed at the location where C and T are marked (two lines are formed), it is a negative non-smoker, and if a line is formed at the position marked C and a line is not formed at the position marked T, it can be read as a smoker. there is.

The smoking tester 1 according to the present embodiment discloses a configuration capable of testing saliva without the medium of a separate moisture absorbing means for delivering saliva to the strip 20 . Due to the cover 301 that opens and closes, the strip 20 does not have a problem of external contamination until the test, and during the saliva test, the protrusion 103 used to fasten the cover 301 stimulates the tongue to promote saliva secretion. In addition, a well slightly recessed around the strip 20 is formed in the detection unit 101 so that the strip 20 can sufficiently contact and flow into the saliva.

Accordingly, in the smoking tester 1 according to the present embodiment, saliva directly penetrates the strip just by contacting the tongue for a short time (within 30 seconds) without the inconvenience of having to bite for more than 1 minute, and chromatographic separation is achieved. possible. The smoking test device 1 is to cover the cover 301 again after the test subject finishes the test, and it can be treated hygienically so that saliva does not stick to other places.

Hereinafter, the configuration of the smoking tester 1 according to the present embodiment will be described in detail.

4 shows the structure of the lower plate 10 in an exploded view of the smoking tester 1 according to an embodiment of the present invention.

The lower plate 10 accommodates the strip 20, and the strip 20 is exposed to form a detection unit 101 in contact with the subject's tongue. The strip 20 may contain a target material 22 that reacts with saliva to detect smoking.

The lower plate 10 may be formed by protruding a predetermined fastening pin 15 on the inside. A plurality of fastening pins 15 may be provided and bind the top plate 30 .

The strip 20 is an indicator for detecting smoking, and a chemical indicator for detecting nicotine or cotinine, a metabolite of nicotine, may be provided as the target material 22 . In addition, the strip 20 may include a color change indicator, and a color change line may be formed at a specific position of the strip with nicotine or cotinine contained in saliva. An example of the target material 22 may be CYP2A6, and in addition, an enzyme that reacts with both nicotine and cotinine, a by-product of nicotine, may be selected. The included color change indicator may be a material that changes color by detecting a metabolite formed from nicotine or cotinine in response to the target material 22 . In this embodiment, the color change indicator may include any one of Cloramine-T, Potassium thiocyanate, Citrate buffer, or Diethylthiobarbituric acid, or all four may be coated. In addition, in this embodiment, the color change indicator may be composed of a material that reacts with 3'-hydroxycotinine.

The lower plate 10 may have a slot-shaped protruding detection unit 101 extended at the front end. The detection unit 101 refers to a contact area through which saliva is introduced by a subject. A part of the front end of the strip 20 accommodated inside the lower plate 10 is exposed to the detection unit 101 . The subject's tongue contacts the end of the strip 20 exposed to the detector 101 to introduce saliva.

The detector 101 has a groove structure so that the strip 20 is exposed in close contact with the bottom surface of the lower plate 10 . A guide groove 130 accommodating the strip 20 is formed on the inside of the lower plate 10. The guide groove 130 at the front end located on the side of the detection unit 101 has no step with the bottom surface of the lower plate 10. . Accordingly, the strip 20 is exposed in the detection unit 101 in a state of being in close contact with the bottom of the lower plate 10, and due to the partition of the guide groove 130 at the tip formed in the detection unit 101, the inside of the detection unit 101 is At the periphery of the strip 20, a finely recessed well structure is formed. The height of the finely submerged wells may correspond to the thickness of the strip 20 . Accordingly, when the subject's tongue touches the detection unit 101, the tongue touches the strip 20, and the remaining amount of secreted saliva is accommodated in the well structure of the detection unit 101, and the saliva is applied to the strip 20. It can be configured to be sufficiently introduced.

The detection unit 101 may be formed with a convexly protruding protrusion 103 . In this embodiment, the protrusion 103 may be formed at the front end of the detection unit 101 . Two protrusions 103 may be formed on both sides of the detection unit 101 . The protrusion 103 serves as a fastening means of the cover 301 that closes the strip 20, and can stimulate the tongue of the test subject in contact with the strip 20. When the subject's tongue touches the detection unit 101, the protrusion 103 automatically stimulates the tongue on both sides of the strip 20 to promote salivation, so the detection unit 101 can detect even a short time of tongue contact. Enough saliva is allowed to enter the strip (20).

The lower plate 10 may have a guide groove 130 in which the strip 20 is accommodated. The guide groove 130 may include partition walls for fixing both sides of the strip 20 . At this time, the guide groove 130 may be formed by protruding from the inner bottom surface to a predetermined height. The guide groove 130 is formed in an embossed shape with protruding partition walls, and the bottom surface between the partition walls is formed in a negative shape. At this time, the bottom surface between the partition walls is slightly higher than the bottom surface of the lower plate 10, and a step 131 is formed. pay attention to Referring to FIG. 4 , it can be confirmed that the bottom inside the lower plate 10 is more submerged than the bottom surface of the detection unit 101 . The height of the submerged minute may be the height of the step 131 .

As the guide groove 130 rises to a height of the step 131 above the bottom surface of the lower plate 10, the strip 20 accommodated in the guide groove 130 floats by a small height from the bottom surface of the lower plate 10. and can be accepted. At this time, it is advantageous that the strip 20 is accommodated so as not to completely contact the bottom surface of the lower plate 10. To this end, in the lower plate 10, the guide grooves 130 accommodating the strips 20 are discontinuously formed in the longitudinal direction so that the strips 20 can be spaced apart from the bottom surface at intervals between the guide grooves 130. do.

Referring to FIG. 4 , it can be seen that a total of four guide grooves 130 are formed at intervals. As the guide grooves 130 do not form a continuous length and are spaced discontinuously in the middle, the strips 20 are accommodated so as to float from the bottom surface of the lower plate 10 at intervals between the guide grooves 130. When the mixture is separated along the mobile phase of the strip 20, other contact surfaces are minimized in the chromatographic separation process, and at the same time, even if saliva overflows into the lower plate 10 and flows in, the middle of the strip 20 Avoid inflow of saliva during the separation process.

A protruding pressing portion 133 may be formed in the guide groove 130 . In FIG. 4 , a pressing part 133 is formed in the guide groove 130 located at the front end of the four guide grooves 130 . The pressing part 133 may be raised in the shape of a convex spherical surface. The guide groove 130 at the front end where the pressing part 133 is located may be a position where a target material of the strip 20 is prepared when the strip 20 is accommodated. Accordingly, the pressing unit 133 may press the target material 22 of the strip 20 accommodated in the guide groove 130 .

The pressing unit 133 prevents the saliva flowing in from the detection unit 101 from being absorbed beyond the target material 22 of the strip 20 . In addition, the pressing unit 133 may serve as a fixing point for floating the strip 20 so that it does not touch the bottom of the lower panel 10 inside the lower panel 10, which is a region after the detection unit 101. Accordingly, the strip 20 may be accommodated to float at a predetermined height along the guide groove 130 from one end fixed to the pressing part 133 in the inner region of the lower plate 10 after the detection unit 101 .

A predetermined cutout 303 is formed on the upper surface of the upper plate 30 to express the detection result of the strip 20 . On one side of the incision 303, marks of C and T, which can confirm the detection result, may be written. The upper plate 30 may be fastened to the protrusion 103 to form a cover 301 that opens and closes the detection unit 101 .
