Description

Technical Field

[0001] The utility model relates to the technical field of tuberculin skin test equipment, in particular to an integrated measuring ruler for tuberculin skin test and new tuberculin skin test. Background Technique

[0002] The detection methods for judging Mycobacterium tuberculosis infection include tuberculin skin test (TST), new tuberculin skin test (C-TST), and interferon-γ release assay.

[0003] At present, both tuberculin skin test (TST) and new tuberculin skin test (C-TST) are tests for diagnosing type IV delayed hypersensitivity caused by Mycobacterium tuberculosis infection by intradermal injection of immunogen and according to the skin reaction at the injection site. Among them, TST uses purified protein derivative of tuberculin (PPD) as the immunogen, and C-TST uses recombinant Mycobacterium tuberculosis fusion protein (EC) as the immunogen.

[0004] The operation methods of the two detection reagents are the same, but the diagnostic criteria are different. The similarities are that the skin reaction measurement results are used as the basis for judging whether the body is infected with Mycobacterium tuberculosis. The differences are that TST sets three control lines at 5 mm, 10 mm, and 15 mm, and the result judgment is divided into negative (induration diameter < 5 mm), general positive (5 mm ≤ induration diameter < 10 mm), moderate positive (10 mm ≤ induration diameter < 15 mm), and strong positive (induration diameter ≥ 15 mm); while C-TST uses a red halo or induration diameter of 5 mm as the control line, and the result judgment is negative (red halo or induration diameter < 5 mm), positive (red halo or induration diameter > 5 mm). In actual work, if the same measuring ruler with three control lines is used, due to the inconsistent interpretation criteria of the two, it is easy to misinterpret the results during the new tuberculin skin test, which affects the judgment of the body's infection status. There is an error in the interpretation method.

[0005] Therefore, the technical personnel in this field have provided an integrated measuring ruler for tuberculin skin test and new tuberculin skin test to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The utility model provides an integrated measuring ruler for tuberculin skin test and new tuberculin skin test to adapt to the measurement of the results of tuberculin skin test and new tuberculin skin test.

[0011] Further, the length of the sliding scale plate is half of the length of the fixed scale plate.

[0012] Further, the number of the buckles is two.

[0013] Further, a straight scale line is arranged at the front edge of the long side of the rectangle on the fixed scale plate.

[0014] Further, the center of the detection circle coincides with the origin of the cross scale line layer on the right side, and the diameter of the detection circle is 5 mm.

[0015] Further, the zero points of the straight scale lines at both left and right ends of the fixed scale plate are flush with the horizontal scale lines of the corresponding cross scale lines.

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0029] See Figure 1-2 shown;

[0030] The integrated measuring ruler for tuberculin skin test and new tuberculin skin test according to the embodiment of the present utility model includes:

[0031] Fixed scale plate 10, the fixed scale plate is a transparent rectangular flexible scale plate. Cross scale line layers 11 are respectively arranged at both ends of the front surface of the fixed scale plate 10. A concentric circle layer 12 is arranged on the cross scale line layer 11 on the left side. The concentric circle layer 12 includes three concentric circles. The diameters of the three concentric circles are 5mm, 10mm and 15mm respectively, and are marked with blue, yellow and red colors respectively. The centers of the three concentric circles coincide with the origin of the corresponding cross scale line layer 11. The three concentric circles are selected with different colors to facilitate the convenient reading of measurement data. The combination of the concentric circle layer 12 and the cross scale line layer 11 on the left side is used for the measurement of tuberculin skin test (TST). A detection circle 13 is arranged on the cross scale line layer 11 on the right side. The center of the detection circle 13 coincides with the origin of the cross scale line layer 11 on the right side. The diameter of the detection circle 13 is 5mm. The detection circle 13 is used synchronously with the cross scale line layer 11 to facilitate the quick reading of measurement data. The combination of the detection circle 13 and the cross scale line layer 11 on the right side is used for the measurement of the new tuberculin skin test (C-TST). The same above structure can accurately measure the different induration and flush diameters of tuberculin and new tuberculin. A hollow groove 14 is formed by inward depression in the middle of the front surface of the fixed scale plate 10. The hollow groove 14 is arranged between the two cross scale line layers 11;

[0032] Sliding scale plate 20, the sliding scale plate 20 is an opaque rectangular flexible scale plate. The sliding scale plate 20 is slidably arranged in the middle of the front surface of the fixed scale plate 10. A buckle 21 is arranged in the middle of the sliding scale plate 20. The buckle 21 can slide in the hollow groove 14.

[0033] The scale surfaces of the fixed scale plate 10 refer to the two largest side surfaces on both sides in the thickness direction of the fixed scale plate 10. The scale surfaces of the sliding scale plate 20 refer to the two largest side surfaces on both sides in the thickness direction of the sliding scale plate 20. The area of the scale surface of the sliding scale plate 20 is one-half of the area of the fixed scale plate 10.

[0034] During specific use, by moving the sliding scale plate 20, the cross scale line layers 11 on the left and right sides can be blocked as required. The cross scale line layer 11 on the left side and the three concentric circles of different colors are used for the measurement of tuberculin skin test (TST). The combination of the cross scale line layer 11 on the right side and the detection circle 13 is used for the measurement of the new tuberculin skin test (C-TST). It can avoid the situation that the existing technology affects the reading of the measurement size due to the use of multiple concentric circles. It completely avoids the situation that the judgment result is easily misjudged due to inconsistent judgment criteria, which affects the judgment of the body's infection status.

[0035] The buckle 21, the sliding scale plate 20 and the hollow groove 14 are of non-detachable structure.

[0036] During the detection process, an integrated measuring ruler is used, which can realize the classified measurement of the results of two detection reagents. At the same time, since different layers are clearly set at the left and right ends, it is possible to avoid the situation that affects the judgment of the infection status of the person being detected due to different judgment criteria. At the same time, the combination of the detection circle 13 and the cross scale line layer 11 on the right side and the combination of the concentric circle layer 12 and the cross scale line layer 11 on the left side can facilitate the reading of data.

[0037] The length of the sliding scale plate 20 is half of the length of the fixed scale plate 10. When the buckle 21 slides to the leftmost end of the hollow groove 14, the sliding scale plate 20 blocks the vertical scale line of the cross scale line layer 11 on the left side. When the buckle 21 slides to the rightmost end of the hollow groove 14, the sliding scale plate 20 blocks the vertical scale line of the cross scale line layer 11 on the right side. This avoids the simultaneous use of the two cross scale line layers 11.

[0038] The number of the buckles 21 is two, which avoids the rotation of the sliding scale plate 20 along the axis of the buckle 21 and affects the use.

[0039] A straight scale line 15 is provided at the front edge of the long side of the rectangle on the fixed scale plate 10. The zero points of the straight scale lines 15 at the left and right ends of the fixed scale plate 10 are flush with the horizontal scale lines of the corresponding cross scale line layer 11. The zero points of the straight scale lines 15 at the top and bottom of the front surface of the fixed scale plate 10 are aligned with the vertical scale lines of the corresponding cross scale line layer 11.

[0040] When in use, the fixed scale plate 10 can be closely attached to the arm. According to the selection of the on-site detection reagent, the sliding scale plate 20 can slide left and right to block the cross scale line layer 11 on the opposite side. The diameter of the induration or flushing can be measured using the cross scale line layer 11 on the corresponding side of the fixed scale plate 10 or the straight scale line 15 near the indicated straight edge. The scale origin of the cross scale layer 11 is aligned with the central position of the induration or flushing on the arm, and then the size of the concentric circle or detection circle is compared with that of the induration or flushing. Therefore, it is beneficial to correctly use the measuring tool, and the numerical reading is more accurate and convenient.
