Description

Technical Field

[0001] This utility model relates to the field of medical teaching equipment, and in particular to a dial-type teaching aid for locating internal hemorrhoids. Background Technology

[0002] Hemorrhoids are the most common anorectal disease in clinical practice. Internal hemorrhoids are formed by pathological changes in the supporting structures of the anal cushions, the venous plexus, and arteriovenous anastomoses, leading to congestion, hyperplasia, hypertrophy, and displacement of the anal cushions. When internal hemorrhoids are detected, the lithotomy position and the knee-chest position are commonly used for localization. The location of the lesion can be recorded using a clock. Internal hemorrhoids commonly occur at the 3, 7, and 11 o'clock positions in the lithotomy position, while they occur at the 1, 5, and 9 o'clock positions in the knee-chest position. The location points in the two positions are completely opposite on a clock face. In actual teaching, some students have a poor sense of spatial orientation and often confuse the two positions, which directly affects the accuracy of locating the common sites of hemorrhoids.

[0003] In current teaching, teachers rely heavily on pictures for explanations, lacking corresponding demonstration tools. This places high demands on students' three-dimensional anatomical understanding, making it difficult for them to comprehend. As a result, teaching effectiveness is unsatisfactory, and demonstrations are not intuitive, hindering students' learning about internal hemorrhoids. Furthermore, the lack of appropriate models also increases the difficulty of clinical education when medical staff explain the common locations of internal hemorrhoids in different body positions to patients and their families.

[0004] Therefore, it is evident that the existing dial-type internal hemorrhoid localization teaching aids still have inconveniences and defects in terms of structure, method, and use, and urgently need further improvement. How to create a new dial-type internal hemorrhoid localization teaching aid that can intuitively display the localization model of common internal hemorrhoid sites in two different positions, lithotomy and knee-chest, with a simple structure, novel design, and convenient use, making it easy for students and related medical workers to understand the relevant knowledge of common internal hemorrhoid sites in these two positions, and also facilitating health education for medical personnel, patients, and their families, has become a pressing goal for the industry. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a dial-type teaching aid for locating internal hemorrhoids, which can intuitively display the location model of the common sites of internal hemorrhoids in two different body positions: lithotomy position and knee-chest position. It has a simple structure, novel design, and is easy to use. It is easy for students and related medical workers to understand the relevant knowledge about the common sites of internal hemorrhoids in the two different body positions, and it is also convenient for medical staff to conduct health education with patients and their families, thereby overcoming the shortcomings of existing internal hemorrhoid demonstration teaching aids.

[0006] To solve the above technical problems, this utility model provides a dial-type internal hemorrhoid positioning teaching aid, including a back plate, a positioning disc and an outer ring of digital blocks. The back plate is provided with 12 outer ring grooves evenly arranged in a circle.

[0007] The positioning disc is rotatably mounted on the back plate, and the positioning disc has 12 outer ring through holes that correspond one-to-one with the outer ring grooves. The positioning disc has a positioning diagram at its center.

[0008] The outer ring number blocks include 12 blocks. The front of each outer ring number block is marked with the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, respectively, and the back of each outer ring number block is marked with the numbers 7, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, and 6, respectively. The 12 outer ring number blocks are used to insert into the 12 outer ring through holes on the positioning plate and the corresponding outer ring grooves on the back plate, respectively, to display the clock position corresponding to the positioning diagram.

[0009] In a further improvement, the back plate is provided with 12 inner ring grooves on the inner side of the 12 outer ring grooves, and the 12 inner ring grooves are arranged radially in one-to-one correspondence with the 12 outer ring grooves. The body positioning plate is provided with 12 inner ring through holes corresponding to the 12 inner ring grooves.

[0010] It also includes 12 inner ring number blocks. The front of each inner ring number block is marked with the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, respectively, and the back of each inner ring number block is marked with the numbers 7, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, and 6, respectively. The 12 inner ring number blocks are used to insert into the 12 inner ring through holes on the positioning plate and the inner ring grooves on the corresponding back plate, for displaying the clock position in the opposite position to that of the outer ring number blocks.

[0011] In a further improvement, the number blocks marked with the numbers 3, 7, and 11 on the front of the outer ring number blocks are set to a different color from the other number blocks to indicate the common sites of internal hemorrhoids.

[0012] In a further improvement, the number blocks marked with the numbers 1, 5, and 9 on the front of the inner circle number blocks are set to a different color from the other number blocks to indicate the common sites of internal hemorrhoids.

[0013] As a further improvement, the outer and inner ring number blocks adopt columnar structures of different shapes.

[0014] In a further improvement, both the outer and inner ring number blocks adopt a cylindrical structure, and the diameter of the cylindrical structure of the outer ring number block is larger than the diameter of the cylindrical structure of the inner ring number block.

[0015] As a further improvement, the back plate is vertically supported by a base.

[0016] In a further improvement, the outer side of the positioning disc is also provided with a rotatable positioning pointer, the axis of which is fixed on the back plate, and the positioning disc rotates around the axis of the positioning pointer.

[0017] In a further improvement, the positioning pointer has a hollow structure in the middle, so that when the positioning pointer points to the outer ring number block, the corresponding inner ring number block can be seen.

[0018] In a further improvement, the outer side of the positioning plate is provided with three positioning pointers, which rotate relative to the back plate.

[0019] With this design, the present invention has at least the following advantages:

[0020] This utility model features a dial-type hemorrhoid positioning teaching aid. By incorporating grooves on the back panel, through holes on the positioning disc, and detachable digital blocks, it forms a detachable dial-type teaching aid distributed according to clock positions. Combined with the external diagram on the positioning disc, this allows students to install digital blocks in different directions for different external positions, providing a more intuitive understanding of the common sites of internal hemorrhoids in different body positions. This aids in student learning and the dissemination of related knowledge about internal hemorrhoids. The structure is simple, the design is novel, and it is easy to use.

[0021] Furthermore, the design of inner and outer rings, as well as the hollowed-out pointers, better reflects the correspondence between various points under different body positions.

[0022] Furthermore, the use of color and shape differentiation helps in teaching the location of common sites for internal hemorrhoids, thus improving the quality of teaching. Attached Figure Description

[0030] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Specific embodiments are as follows.

[0031] See attached document Figures 1 to 3 As shown, the dial-type internal hemorrhoid positioning teaching aid in this embodiment includes a support 1, a positioning disc 2, an outer ring number block, and an inner ring number block.

[0032] like Figure 1 As shown, in this embodiment, the bracket 1 includes a base 11 and a back plate 12 vertically fixed to the base 11. The back plate 12 has 12 outer ring grooves 121 and 12 inner ring grooves 122 arranged in a circular, evenly distributed pattern on its side, with each of the 12 outer ring grooves 121 and 12 inner ring grooves 122 arranged radially in a one-to-one correspondence. Of course, the back plate 12 can also be provided independently, or it can be used to form a suspended back plate structure via hooks.

[0033] like Figure 2 As shown, in this embodiment, the positioning disc 2 is rotatably mounted on the back plate 12, and the positioning disc 2 is provided with 12 outer ring through holes 21 and 12 inner ring through holes 22 corresponding to the outer ring groove 121 and the inner ring groove 122. The positioning disc 2 is provided with a positioning diagram 23 at its center.

[0034] like Figure 3 As shown, in this embodiment, the outer ring number blocks include 12 blocks. The front of each outer ring number block is marked with the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, respectively, and the back of each outer ring number block is marked with the numbers 7, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, and 6, respectively. The 12 outer ring number blocks are used to insert into the 12 outer ring through holes 21 on the positioning plate 2 and the corresponding outer ring grooves 121 on the back plate 12, respectively, to display the clock position corresponding to the positioning diagram 23 and to fix the position of the positioning plate 2.

[0035] like Figure 4As shown, the inner ring number blocks include 12 blocks. The front of each inner ring number block is marked with the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, respectively, and the back of each inner ring number block is marked with the numbers 7, 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, and 6, respectively. The 12 inner ring number blocks are used to insert into the 12 inner ring through holes 22 on the positioning plate 2 and the corresponding inner ring grooves 122 on the back plate 12, for displaying the clock position in the opposite position to that of the outer ring number blocks.

[0036] In a preferred embodiment, the outer surface of the positioning disc 2 is further provided with at least one rotatable positioning pointer 13, preferably three. The three positioning pointers 13 rotate separately, either simultaneously pointing in one direction or pointing in three different directions. The rotation axis 131 of the positioning pointer 13 is fixed to the back plate 12, and the positioning disc 2 rotates around the rotation axis 131 of the positioning pointer 12 to display different body positions, as shown in the attached figure. Figure 5 The lithotomy site was shown outside the body, attached Figure 6 The knee-chest position is shown outside the body.

[0037] Furthermore, in this embodiment, the positioning pointer 13 has a hollow structure 132 in the middle. The hollow structure 132 allows the corresponding inner circle number block to be seen when the positioning pointer 13 points to the outer circle number block.

[0038] A more preferred embodiment is that the number blocks marked with the numbers 3, 7, and 11 on the front of the outer ring are set to a different color than the other number blocks, such as red, while the other number blocks are green. Similarly, the number blocks marked with the numbers 1, 5, and 9 on the front of the inner ring are set to a different color than the other number blocks, such as red and green, or other colors. Of course, other colors can also be used, as long as the corresponding number blocks can be distinguished. In this way, the outer and inner ring number blocks with distinguished colors, together with three positioning pointers, can more intuitively display the location of the common site under the lithotomy position, as shown in the attached figure. Figure 5 As shown.

[0039] Furthermore, the outer ring number blocks (numbers 9, 1, 5 on the back) and the inner ring number blocks (numbers 7, 11, 3 on the back), after being distinguished by color, can also more intuitively display the location of common sites in the knee-chest position, as shown in the attached image. Figure 6 As shown.

[0040] Furthermore, in this embodiment, both the outer and inner ring number blocks adopt a cylindrical structure, and the diameter of the cylindrical structure of the outer ring number block is larger than the diameter of the cylindrical structure of the inner ring number block, which facilitates the differentiation between the outer and inner ring number blocks. Of course, the outer and inner ring number blocks can also adopt cylindrical structures of different shapes for differentiation.

[0041] The method of using this dial-type internal hemorrhoid positioning teaching aid is as follows: first, remove all the number blocks from the support 1, then rotate the positioning disc 2 to position it in the lithotomy position or the knee-chest position.

[0042] If positioned in the lithotomy position, insert the outer ring number blocks into the outer ring groove 121 of the backplate 12 according to the clock direction of the lithotomy position to display the clock position under the lithotomy position, and visually display the common sites of internal hemorrhoids under this position through colored number blocks; and insert the inner ring number blocks into the inner ring groove 122 of the backplate 12. The inner ring number blocks are used to more intuitively display the knee-chest point position corresponding to each point of the lithotomy position, as shown in the attached figure. Figure 5 As shown.

[0043] Then, remove all the digital blocks and rotate the positioning disc 2 to position it in the knee-chest position, as shown. Figure 6 As shown. Then, the students put the number blocks for common sites under the knee-chest position into the outer groove, and then put the number blocks for the inner groove into the inner groove, forming a one-to-one correspondence between the lithotomy position and the knee-chest position, thus achieving the teaching objective for students and helping them understand the relevant knowledge about internal hemorrhoids.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
