[0043] The utility model relates to medical teaching mould technical field, concretely is a kind of teaching mould for tuberculin skin test teaching, the main body technical scheme content of the utility model is specifically explained below in conjunction with multiple embodiments. Among them, example 1 is explained clearly, detailedly to the technical scheme content of the utility model in conjunction with the drawing of specification-just Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5 Example 4 is explained clearly, detailedly to the technical scheme content of the utility model in conjunction with the drawing of specification-just Figure 6 、 Figure 7 、 Figure 8 And Figure 9 Although the main structure of other embodiments can still refer to the drawing of example 1 or example 4, but it is not separately drawn.
[0044] It needs to be specially stated here that the drawing of the utility model is schematic, and unnecessary details have been simplified in order to clarify the technical purpose of the utility model, to avoid obscuring the technical scheme of the utility model contributed to the prior art. In addition, the "about", "basically" and other expressions about quantity or cooperation relationship in the following are expressed to allow reasonable assembly error, machining error, etc. exist, not literal expression absolute quantity or cooperation relationship.
[0045] Example 1
[0046] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 5 The utility model is a kind of teaching mould for tuberculin skin test teaching, and it includes shell 1, hard knot simulation assembly 2 and interpretation card 3.
[0047] Specifically, the shell 1 is a flat structure, which is a carrier for assembling the hardening simulation assembly 2 and the interpretation card 3. The shell 1 has a front side flexible diaphragm 11 and a rear side support plate 12, which are bonded together to form a sliding groove 13 capable of accommodating the hardening simulation assembly 2 in the length direction.
[0048] More specifically, the support plate 12 is a hard structure with a relatively hard texture, and the material is not limited, which is a support carrier of the entire teaching mold. At the top side and bottom side edges of the support plate 12, there are slightly bent forward forming edges, which on the one hand form the basis for bonding and fixing with the flexible diaphragm 11, and on the other hand ensure the stable formation of the sliding groove 13, so that the hardening simulation assembly 2 assembled in the sliding groove 13 can be slidably displaced. The length and height of the support plate 12 are greater than the length and height of the hardening simulation assembly 2. In terms of length, the length of the support plate 12 is usually 2 times the length of the base plate 21 of the hardening simulation assembly 2, to ensure the cooperation of the displacement of the hardening simulation assembly 2 in the shell 1, i.e. the length of the sliding groove 13 of the shell 1 can make each simulation hardening on the hardening simulation assembly 2 correspondingly displayed on the transparent area 14 of the flexible diaphragm 11, and each simulation hardening of the hardening simulation assembly 2 is in the sliding groove 13; in terms of height, the height of the support plate 12 is slightly greater than the height of the base plate 21 of the hardening simulation assembly 2, so that the hardening simulation assembly 2 can be freely slidably displaced in the sliding groove 13 of the shell.
[0049] The flexible diaphragm 11 is a plastic film structure, which is bonded and fixed at the edges of the top side and bottom side of the support plate 12 in the height direction of the support plate 12, and cooperates with the support plate 12 to form a sliding groove 13 for accommodating the hardening simulation assembly 2. The flexible diaphragm 11 on the shell 1 serves as a work surface for the trainee to touch and perceive and view the hardening simulation assembly 2, which is composed of a transparent area 14 and a non-transparent area 16. The transparent area 14 is formed at the middle of the entire flexible diaphragm 11, and its displayable area is greater than the maximum size of the simulation hardening on the hardening simulation assembly 2, i.e. the simulation hardening 22 described below. In order to intuitively view and grasp the size of the simulation hardening, a millimeter-level measurement scale 15 is formed at the center of the transparent area 14 of the flexible diaphragm 11; since the structure of the hardening reaction in the actual tuberculin skin test is irregular, the measurement scale 15 should adopt a cross scale structure that can measure in the height direction and the length direction. Of course, combined with the scales in the height direction and the length direction, reference lines with specific distances can also be formed in the circumferential direction, such as 5mm, 10mm, 15mm, etc. The aforementioned flexible diaphragm 11 adopts a transparent structure film and two non-transparent structure films bonded or heat-fused as a whole structure.
[0050] The shell 1 composed of the flexible diaphragm 11 and the support plate 12 is opened at at least one end in the length direction for the convenience of inserting the hardening simulation component 2, i.e. the sliding groove 13 is opened at the corresponding end for the insertion of the hardening simulation component 2.
[0051] In order to enable the hardening simulation component 2 inserted into the shell 1 to move in the sliding groove 13 for displaying the simulation hardening in different forms on the transparent area 14 of the flexible diaphragm 11, the shell 1 is formed with a push gap 17 communicating with the sliding groove 13 for the operator to touch the hardening simulation component 2 with fingers. In the embodiment, the push gap 17 of the shell 1 for pushing the hardening simulation component 2 to move in the sliding groove 13 is formed as an inward recess gap structure at the top side of the hardening simulation component 2 in the moving direction, which is basically at the middle of the shell 1 in the length direction; the hardening simulation component 2 assembled in the shell 1 has the top side edge of the base plate 21 exposed at the corresponding push gap 17.
[0052] The shell 1 with the above structure is further connected with a hard structure (basically the same material as the support plate 12) of the surrounding plate 110 at the back side surface of the support plate 12 for the convenience of carrying the interpretation card 3, the bottom side and both ends in the length direction of the surrounding plate 110 are bonded with the support plate 12 as a whole, and are segmentedly bonded in the length direction, so that the surrounding plate 110 and the support plate 12 form a plurality of card insertion slots 19 opening upward in the length direction, each of which is used for inserting at least one interpretation card 3. The interpretation card 3 records the theoretical knowledge points of the tuberculin skin test to ensure that the students can easily and flexibly find the corresponding theoretical knowledge points through the interpretation card 3 to strengthen the memory when they perform the practical simulation operation.
[0053] The hardening simulation assembly 2 has a base plate 21 and four simulation hardenings. The base plate 21 adopts a hard structure, and its texture is basically the same as that of the support plate 12 of the shell 1, which serves as a carrier for arranging the four simulation hardenings. The base plate 21 takes the surface matched with the flexible diaphragm 11 of the shell 1 as the simulation operation surface, and the four simulation hardenings are fixed on the simulation operation surface of the base plate 21 at a fixed interval, and the interval arrangement track of the four simulation hardenings on the base plate 21 corresponds to the displacement direction of the hardening simulation assembly 2 in the shell 1, i.e. the length direction. In order to align the simulation hardenings with the center of the measurement scale 15 on the shell 1 during the displacement of the hardening simulation assembly 2, the centers of the four simulation hardenings are basically at the same height on the base plate 21, and when the hardening simulation assembly 2 is installed in the shell 1, the height positions of the centers of the four simulation hardenings are basically the same as the height of the measurement scale 15. Corresponding to the judgment standard of the hardening reaction in the tuberculin skin test, the four simulation hardenings on the aforementioned hardening simulation assembly 2 are respectively simulation hardening one 22 with a hardening diameter ≥ 15 mm (such as 15 mm or 20 mm, etc.), simulation hardening two 23 with a hardening diameter ≥ 10 mm but < 15 mm (such as 13 mm or 10 mm, etc.), simulation hardening three 24 with a hardening diameter ≥ 5 mm but < 10 mm (such as 8 mm or 5 mm, etc.), and simulation hardening four 25 with a hardening diameter < 5 mm (such as 3 mm or 1 mm, etc.).
[0054] The hardening simulation assembly 2 with the above structure is transversely installed in the sliding groove 13 of the shell 1 through the opening at the length direction end of the shell 1, i.e. the hardening simulation assembly 2 is movably installed in the shell 1 in a telescopic manner, and each simulation hardening on the hardening simulation assembly 2 faces the flexible diaphragm 11 of the shell 1, which covers the hardening simulation assembly 2 on the simulation operation surface of the hardening simulation assembly 2. The operator transversely moves the hardening simulation assembly 2 at the poking gap 17 of the shell 1, and the hardening simulation assembly 2 can be relatively displaced based on the transparent area 14 on the flexible diaphragm 11, so that the simulation hardening currently needed to be recognized is located at the non-transparent area 16 or the transparent area 14 of the flexible diaphragm 11. Based on the matching relationship between the hardening simulation assembly 2 and the shell 1, as described above, the length of the sliding groove 13 on the shell 1 in the displacement direction of the hardening simulation assembly 2 should be greater than the length of the base plate 21 of the hardening simulation assembly 2, and the length of the sliding groove 13 can make each simulation hardening on the hardening simulation assembly 2 not exposed in the displacement direction when each simulation hardening on the hardening simulation assembly 2 is displayed on the transparent area 14 of the flexible diaphragm 11.
[0055] Embodiment 2
[0056] The other contents of this embodiment are the same as those of Embodiment 1, except that:
[0057] The bottom side of the shell is also formed with a poking gap at the middle part, which is basically symmetrically distributed with the poking gap at the top side.
[0058] Example 3
[0059] The other contents of this embodiment are the same as those of Example 1, except that:
[0060] The toggle notch at the top side of the shell is removed, and the toggle notch is formed at the middle of the bottom side of the shell.
[0061] Example 4
[0062] Referring to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , the utility model discloses a teaching mold for tuberculin skin test teaching, which comprises a shell 1 and a hard knot simulation assembly 2.
[0063] Specifically, the shell 1 is a flat structure, which is a carrier for assembling the hard knot simulation assembly 2. The shell 1 has a flexible diaphragm 11 on the front side and a support plate 12 on the back side, which are bonded together to form a sliding groove 13 in the length direction, which can accommodate the hard knot simulation assembly 2.
[0064] More specifically, the support plate 12 is a hard structure with a relatively hard texture, and the material is not limited. It is the support carrier of the entire teaching mold. On the top side and the bottom side edge of the support plate 12, there are slightly bent edges formed in the front direction, which on the one hand form the basis for bonding and fixing with the flexible diaphragm 11, and on the other hand ensure the stable formation of the sliding groove 13, so that the hard knot simulation assembly 2 assembled in the sliding groove 13 can be slidably displaced. The length and height of the support plate 12 are both greater than the length and height of the hard knot simulation assembly 2. In terms of length, the length of the support plate 12 is usually 2 times the length of the base plate 21 of the hard knot simulation assembly 2, to ensure the cooperation relationship of the displacement of the hard knot simulation assembly 2 in the shell 1, i.e. the length of the sliding groove 13 of the shell 1 can make each simulation hard knot on the hard knot simulation assembly 2 correspondingly displayed on the transparent area 14 of the flexible diaphragm 11, and each simulation hard knot of the hard knot simulation assembly 2 is in the sliding groove 13. In terms of height, the height of the support plate 12 is slightly greater than the height of the base plate 21 of the hard knot simulation assembly 2, so that the hard knot simulation assembly 2 can be freely slidably displaced in the sliding groove 13 of the shell.
[0065] The flexible diaphragm 11 is a plastic film structure, and is fixedly bonded at the edges of the top side and the bottom side of the support plate 12 in the height direction of the support plate 12, and cooperates with the support plate 12 to form a sliding groove 13 for installing the induration simulation assembly 2. The flexible diaphragm 11 serves as a work surface for the trainee to touch and view the induration simulation assembly 2, and is composed of a transparent area 14 and a non-transparent area 16. The transparent area 14 is formed at the middle of the flexible diaphragm 11, and has a display area larger than the largest size of the simulation induration on the induration simulation assembly 2, i.e., the simulation induration 22 described below. In order to intuitively view and grasp the size of the simulation induration, a millimeter-level measurement scale 15 is formed at the center of the transparent area 14 of the flexible diaphragm 11. Since the structure of the induration reaction in the actual tuberculin skin test is irregular, the measurement scale 15 should adopt a cross scale structure that can measure in the height direction and the length direction. Of course, in combination with the scales in the height direction and the length direction, reference lines of specific distances can also be formed in the circumferential direction, such as 5 mm, 10 mm, 15 mm, etc. The aforementioned flexible diaphragm 11 is integrally formed by bonding or heat melting a transparent film and two non-transparent films.
[0066] In order to facilitate the insertion of the induration simulation assembly 2, the housing 1 composed of the flexible diaphragm 11 and the support plate 12 is provided with an open structure at at least one end in the length direction, i.e., the sliding groove 13 is open at the corresponding end to allow the insertion of the induration simulation assembly 2.
[0067] In order to enable the induration simulation assembly 2 inserted into the housing 1 to move and displace in the sliding groove 13, so that simulation indurations of different shapes are displayed on the transparent area 14 of the flexible diaphragm 11, a poking hole 18 is formed on the housing 1 to allow the operator to touch the induration simulation assembly 2. In the present embodiment, the poking hole 18 for poking the induration simulation assembly 2 to move and displace in the sliding groove 13 is formed in a through-hole structure on the support plate 12 of the housing 1, and the poking hole 18 is a waist-shaped hole structure, with the long axis direction corresponding to the displacement direction of the induration simulation assembly 2 in the housing 1, and being substantially at the middle of the support plate 12 of the housing 1 in the length direction. The back surface of the base plate 21 of the induration simulation assembly 2 assembled in the housing 1 is exposed at the poking hole 18.
[0068] The hardening simulation assembly 2 has a base plate 21 and four simulation hardenings. The base plate 21 adopts a hard structure, and its texture is basically the same as that of the support plate 12 of the shell 1, which serves as a carrier for arranging the four simulation hardenings. The base plate 21 takes the surface matched with the flexible diaphragm 11 of the shell 1 as the simulation operation surface, the four simulation hardenings are fixed on the simulation operation surface of the base plate 21 at a fixed interval, and the interval arrangement track of the four simulation hardenings on the base plate 21 corresponds to the displacement direction of the hardening simulation assembly 2 in the shell 1, that is, the length direction. In order to align the center of each simulation hardening with the center of the measurement scale 15 on the shell 1 during the displacement of the hardening simulation assembly 2, the centers of the four simulation hardenings are basically at the same height on the base plate 21, and when the hardening simulation assembly 2 is installed in the shell 1, the height positions of the centers of the four simulation hardenings are basically the same as the height of the measurement scale 15. Corresponding to the judgment standard of the hardening reaction in the tuberculin skin test, the four simulation hardenings on the aforementioned hardening simulation assembly 2 are respectively simulation hardening one 22 with a hardening diameter ≥ 15 mm (such as 15 mm or 20 mm, etc.), simulation hardening two 23 with a hardening diameter ≥ 10 mm but < 15 mm (such as 13 mm or 10 mm, etc.), simulation hardening three 24 with a hardening diameter ≥ 5 mm but < 10 mm (such as 8 mm or 5 mm, etc.), and simulation hardening four 25 with a hardening diameter < 5 mm (such as 3 mm or 1 mm, etc.).
[0069] The hardening simulation assembly 2 with the above structure is transversely installed in the sliding groove 13 of the shell 1 through the opening at the length direction end of the shell 1, that is, the hardening simulation assembly 2 is movably installed in the shell 1 in a telescopic manner, and each simulation hardening on the hardening simulation assembly 2 faces the flexible diaphragm 11 of the shell 1, which covers the hardening simulation assembly 2 on the simulation operation surface of the hardening simulation assembly 2. The operator transversely moves the hardening simulation assembly 2 through the poking hole 18 of the shell 1, and the hardening simulation assembly 2 can be relatively displaced based on the transparent area 14 on the flexible diaphragm 11, so that the simulation hardening currently needed to be recognized is located in the non-transparent area 16 or the transparent area 14 of the flexible diaphragm 11. Based on the matching relationship between the hardening simulation assembly 2 and the shell 1, as described above, the length of the sliding groove 13 on the shell 1 in the displacement direction of the hardening simulation assembly 2 should be greater than the length of the base plate 21 of the hardening simulation assembly 2, and the length of the sliding groove 13 can make each simulation hardening on the hardening simulation assembly 2 not exposed in the displacement direction when each simulation hardening on the hardening simulation assembly 2 is displayed on the transparent area 14 of the flexible diaphragm 11.

[0072] The operation handle is fixedly connected at the back side of the base plate of the hardening simulation assembly and extends out of the push hole of the shell.
[0073] Based on the operation handle structure and the assembly structure of the hardening simulation assembly and the shell in Embodiment 2, the operation handle should be connected to the base plate of the hardening simulation assembly from the push hole of the shell after the hardening simulation assembly is assembled in place.

[0080] The flexible diaphragm of the shell is fixedly bonded at the back side of the corresponding edge of the support plate.
[0081] The above embodiments are only used to illustrate the present application, but not to limit it.
[0082] Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the above embodiments can be modified, or some technical features can be replaced by equivalent ones; and these modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the present application.
