Description

Technical Field

[0001] This invention relates to the field of medical molds, specifically a medical mold for a human abdominal wound. Background Technology

[0002] Clinical medical and nursing diagnoses require obtaining information about the patient's wound through questioning, observation, examination, and exploration. Based on this information, a differential diagnosis can be made regarding the current state and type of the wound, leading to an accurate assessment and appropriate subsequent treatment. A comprehensive assessment and diagnosis of the wound is essential for healthcare professionals to identify abnormalities, which is a prerequisite for wound care.

[0003] In clinical medical teaching, human anatomy models, acupoints and meridians, skeletal models, organ models, and skin structure models are widely used with significant results. However, in teaching wound-related knowledge, there are currently no human wound medical models available. Students can only rely on textbook descriptions, pictures, and verbal descriptions from teachers to abstractly understand wound size, depth, sinus tracts, undermining, fistulas, etc., and to assess wound problems. This lack of intuitive and sensory understanding often requires repeated trial and error in practice before comprehension. The inability to truly understand and master the material before practical application hinders accurate wound assessment, leading to errors in clinical or nursing diagnosis, delaying treatment, increasing patient suffering and financial burden, affecting physiological functions, and even endangering lives.

[0004] Chinese invention patent application number 202210925475.6 discloses an intelligent teaching model for pediatric gastrointestinal fistula tubes. This teaching model has the advantages of being able to observe the insertion position of the tube and reacting to whether there is depth when the mold is injected or drained, solving the problems of inconvenient observation and inability to react when there is leakage. Chinese utility model patent application number 202221657864.7 discloses a teaching mold for urological drainage tracts. By inserting drainage tubes into various human organs, and opening the surface of the shell with the corresponding stoma for the drainage tubes, and the shell is made of acrylic, making the surface of the shell transparent, the insertion position of the drainage tubes on the human organs is clearly visible, so that students can clearly see the tubes on the urological drainage tract, thus facilitating students' learning. Chinese invention patent application number 202010677831.8 discloses an extracorporeal hemodynamic physical simulation model device for arteriovenous fistulas. This invention can establish a stable vascular model with controllable stenosis.

[0005] In recent years, I have used handmade radish models to simulate various wound shapes in my teaching practice. Compared with text, pictures, and verbal descriptions by the teacher, the understanding and mastery effect is more ideal, but it is not suitable for long-term preservation. How to demonstrate wound conditions more intuitively and clearly using models and vivid explanations, so that students can quickly understand and master them thoroughly, make comprehensive and accurate wound assessments and diagnoses in clinical practice, improve the accuracy of clinical diagnosis and treatment, reduce patient suffering and economic burden, and ultimately benefit patients, is an urgent problem that needs to be solved.

[0016] As a preferred technical solution, the measuring rod includes a vertical cylindrical silicone rod, with a malleable metal wire axially embedded at the center of the silicone rod, and graduations are provided on the outer surface of the silicone rod from bottom to top. A cylindrical handle is fixedly provided at the upper end of the silicone rod, and an annular protrusion is fixedly provided on the outer surface of the silicone rod below the cylindrical handle. An annular groove is also provided on the inner side of the upper end of the protective sleeve to engage with the annular protrusion.

[0017] Compared with the prior art, the present invention provides a medical mold for human abdominal wounds, which has the following beneficial effects: 1. This invention uses an abdominal model consisting of an epidermis, dermis, subcutaneous fat, muscle, and peritoneum from top to bottom. The peritoneum contains models of the liver, stomach, intestines, and bladder. When used, it can clearly show the overall structure of the abdominal cavity, making it easier for students to understand and laying the foundation for understanding various wound morphologies.

[0018] 2. This invention features a wound model embedded downwards at the top center of an abdominal model, a burrowing model inside the upper left of the wound model, a sinus tract model at the bottom left of the base of the wound model, and two fistula models on the right side of the base of the bottom of the wound model. When in use, this structure can clearly demonstrate the differences between wounds, burrowing, sinus tracts, and fistulas to students, facilitating their understanding and memorization.

[0019] 3. The present invention has a perforation at the upper left corner of the abdominal model. When in use, a hanging rope can be fixed at the perforation for easy hanging and carrying, and to prevent the model from being lost.

[0020] 4. This invention features LED strips in the infiltrating model, sinus tract model, and fistula model, each electrically connected to a control board. The control board is electrically connected to a battery box. A speaker is located at the bottom right side of the abdominal model and electrically connected to the control board. The control board also has a sound module that works with the speaker. Three switches are located at the bottom right of the top of the abdominal model. When in use, each switch corresponds to one of the infiltrating model, sinus tract model, or fistula model. Pressing a switch illuminates the corresponding model's LED strip and announces the name of the wound morphology. This vividly and interestingly demonstrates various wound morphologies, facilitating students' quick understanding and thorough mastery. It also enables comprehensive and accurate wound assessment and diagnosis in clinical practice, improving the accuracy of clinical diagnosis and treatment, reducing patient suffering and financial burden, and ultimately benefiting patients.

[0021] 5. The present invention has a removable plug at the upper end of the sinus tract and fistula model.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0030] like Figures 1 to 3As shown, a medical mold for a human abdominal wound includes an abdominal model 1, which is rectangular in shape. From top to bottom, the abdominal model 1 has an epidermal layer 11, a dermal layer 12, a subcutaneous fat layer 13, a muscle layer 14, and a peritoneum layer 15. Inside the abdominal model 1 and below the peritoneum layer 15, there are a liver model 7, a stomach model 10, an intestine model 8, a gallbladder model 71, and a bladder model 9. The top center of the abdominal cavity model 1 is embedded with the wound model 2 (the wound model 2 is a cavity with a bottom and an open top). To the upper left of the wound model 2 and inside the abdominal model 1, there is a hidden model 3 (the hidden model 3 is an invisible, hidden cavity below the epidermal layer 11, which is connected to the cavity of the wound model 2. The wound model 2 is completely surrounded by the hidden model 3. Only a part of the hidden model 3 is shown in the figure). To the lower left of the base of the wound model 2, there is a sinus tract model 4 (the sinus tract model 4 is a blind path that is connected to the cavity of the wound model 2. Its end towards the peritoneum 15 does not penetrate the peritoneum 15). To the right of the base of the wound model 2, there are two fistula models. To the upper left corner of the abdominal model 1, there is a perforation 16 (penetrating the top and back sides). The infiltrating model 3, sinus tract model 4, and fistula model 3 are each equipped with a light strip 100, which is electrically connected to the control board 101. The control board 101 is electrically connected to the battery box 102. The bottom right side of the abdominal model 1 is equipped with a speaker 104, which is electrically connected to the control board 101. The control board 101 is also equipped with a sound module 105 that works with the speaker 104 (stores three voices: sinus tract, fistula, and infiltrating). The top right lower part of the abdominal model 1 is equipped with three switches 103 (which can be set to yellow (sinus tract), red (fistula), and green (infiltrating) respectively). Each switch 103 is electrically connected to the control board 101 through a circuit.

[0031] The illumination range of the LED lights on the light strip 100 of the stealth model 3 can be controlled by switch 103, and the size of the stealth range is displayed by the illumination range.

[0032] The fistula models include bladder fistula model 5 and intestinal fistula model 6. Bladder fistula model 5 and intestinal fistula model 6 are non-blind channels communicating with the cavity of wound model 2. They penetrate the peritoneum 15 at their peritoneal end. The end of bladder fistula model 5 that penetrates the peritoneum 15 communicates with the bladder, and intestinal fistula model 6 communicates with the intestine.

[0033] Both the sinus tract model 4 and the fistula model have removable plugs 21 at their upper ends. When measuring the volume of the sinus tract cavity in the sinus tract model 4, the plugs 21 can be removed, and water can be injected into the sinus tract model 4 using a spare syringe to measure the water volume, thereby measuring the cavity volume of the sinus tract model 4.

[0034] The abdominal model 1 is made of transparent silicone material.

[0035] The head end 18 is located at the middle of the posterior end of the top of the abdominal model 1, and the foot end 19 is located at the middle of the anterior end.

[0036] The top of the abdominal model 1 is marked with raised numbers corresponding to clocks around the wound model 2 (circumferential intervals of 1-12, with the head end at the 12 o'clock position and the foot end at the 6 o'clock position).

[0037] Measure the size of wound model 2 using a measuring ruler, such as Figure 2 As shown, specifically, the vertical distance between ab is measured as the length of wound model 2, and the vertical distance between cd is measured as the width of wound model 2; the vertical distance between the deepest point of plane e (the top surface of abdominal model 1) and plane f (plane f is the inner bottom surface of wound model 2) is measured as the depth of the wound model. For wounds with undermining, the undermining area is represented by plane i (plane i is the plane on which undermining is projected onto the body surface, as shown by the grid in the figure). Within the undermining area, the longest and shortest undermining distances need to be recorded. The longest undermining distance is from the edge of the wound to the point of longest / deepest undermining, denoted by g; the shortest undermining distance is from the edge of the wound to the point of shortest / shallowest undermining, denoted by h. If h = 0.5cm and g = 2cm, then the undermining distance in the direction from 9 o'clock to 1 o'clock is 0.5cm to 2cm.

[0038] When in use, this model clearly displays the overall structure of the abdomen, facilitating student understanding and laying the foundation for understanding various wound morphologies. It also clearly demonstrates the differences between wounds, burrows, sinus tracts, and fistulas, aiding student comprehension and memorization. Sixteen perforations allow for securing a hanging rope, facilitating hanging and carrying, and preventing model loss. Each switch 103 corresponds to the burrow model 3, sinus tract model 4, and fistula model (two light strips). Pressing switch 103 illuminates the corresponding model's light strip 100 and announces the name of the wound morphology, vividly and engagingly showcasing various wound forms. This allows for intuitive and clear visual recognition, facilitating rapid understanding and memorization by students, enabling comprehensive and accurate wound assessment and diagnosis in clinical practice, improving clinical diagnostic accuracy, reducing patient suffering and financial burden, and ultimately benefiting patients. Normal saline can be injected into wound model 2 and sinus tract model 4; the volume of saline when full represents the volume of the wound or sinus tract, facilitating wound and fistula volume measurement. The transparent material allows students to clearly observe the internal connections between the wound and organs. The raised numbers help to represent the location of wound undermining, sinus tracts, and fistulas, further aiding students' understanding. Example 2

[0039] like Figure 4As shown, a transparent film 111 is adhered to the top surface of the abdominal model 1. The transparent film 111 has a ring-shaped marking line 111a extending outwards from the center of the wound model. The accuracy is 0.1 cm. Marking lines 111a within 1 cm are dashed lines (e.g., 0.1cm, 0.2cm, 0.3cm…0.9cm marking lines) and are not marked. Integer marking lines 111a beyond 1 cm are solid lines (e.g., 1.0cm, 2.0cm, 3.0cm marking lines), and marking lines between adjacent integer marking lines 111a are dashed lines (e.g., 1.1cm, 1.2cm, 1.3cm marking lines), and each must be marked with a number. The upper left corner of the transparent film 111 has a through hole (unmarked) that mates with a hanging hole 16, allowing the transparent film 111 to be hung on the hanging hole 16 via a hanging ring to prevent loss. When in use, the transparent film 111 is flipped onto the top surface of the abdominal model 1, and the surface of the transparent film 111 in contact with the abdominal model 1 is an adhesive, re-adhesive surface. The transparent film 111 is adhered to the top surface of the abdominal model 1, and the size of the transparent film 111 matches the size of the top surface of the abdominal model 1. When not in use, the transparent film 111 is separated from the abdominal model 1 and flipped onto the side of the abdominal model 1.

[0040] The transparent film 111 is made of a material that can be written and wiped with an oil pen. The wound can be traced on the top surface of the transparent film 111 by using an oil pen to trace the size of the opening at the top of the wound model 2, so as to more intuitively show the size of the wound and facilitate students' simulation practice.

[0041] When in use, the transparent film 111 is attached to the top surface of the abdominal model 1, which makes it easier to understand the measurement of stealth and wound size, and is more intuitive and clear. Example 3

[0042] like Figure 5 , Figure 6 As shown, a first annular seat 112 with openings at the top and bottom is fixed on one side of the rear side of the abdominal model 1, and a syringe A (pre-existing technology) is vertically slidably inserted into the first annular seat 112.

[0043] A second annular seat 113 with openings at the top and bottom is fixedly provided on the other side of the rear side of the abdominal model 1. A measuring tool B is vertically slidably inserted into the second annular seat 113. The measuring tool B includes an outer protective sleeve B1, which is a cylindrical tube with an opening at the top. An annular boss B2 that mates with the upper surface of the second annular seat 113 is fixedly provided on the outer side of the upper end. A measuring rod B4 is inserted into the protective sleeve B1.

[0044] The measuring rod B4 includes a vertically cylindrical silicone rod (not separately labeled). A malleable metal wire (not shown; copper or aluminum wire can be used to facilitate shaping the silicone rod) is axially embedded at the center of the silicone rod. The outer surface of the silicone rod has graduations B5 from bottom to top. A cylindrical handle B3 is fixedly attached to the upper end of the silicone rod. An annular protrusion B6 is fixedly attached to the outer surface of the silicone rod below the cylindrical handle B3. The inner side of the upper end of the protective sleeve also has an annular groove (not shown) that engages with the annular protrusion B6 to prevent the measuring rod B4 from slipping.

[0045] The transparent film 111 has a hole in the middle that corresponds to the top opening of the wound model 2 and a removable cover. The removable cover is integrated with one side of the hole. The removable cover can cover the hole and can be lifted upwards to expose the hole.

[0046] In use, the volume of the sinus tract model 4 and the wound model 2 can be easily measured directly using the syringe A on the back of the abdominal model 1, eliminating the need for a spare syringe and making it more convenient. The length of the sinus tract model 4 can be measured by opening the removable cap and inserting the measuring rod B4 into the sinus tract model 4. The measuring rod B4 can also be used to measure the size and depth of the wound model 2, and the depth of the undermining model 3. The first annular seat 112 and the second annular seat 113 facilitate the storage of the syringe A and the measuring tool B.
