Description

Technical Field

[0001] The invention relates to the technical field of wound care, and in particular to a method for teaching wound care using injured fruits. Background Art

[0002] The traditional use of molds and pictures as teaching tools in wound teaching has a certain history and application background. With the development of science and technology, the application of virtual simulation technology in teaching also provides students with a richer and more realistic learning experience. However, its shortcomings cannot be ignored. The specific analysis is as follows:

[0003] 1. Disadvantages of molds as teaching tools

[0004] High cost: Mold manufacturing requires high-precision processes and materials, so the cost is usually high. For educational institutions, purchasing and maintaining a large number of molds can be a considerable expense.

[0005] Difficult to update: With the continuous advancement of medical technology, the methods and concepts of wound treatment are also constantly updated. However, once the mold is made, its shape and purpose are relatively fixed, and it is difficult to adapt to new teaching needs.

[0006] Operational limitations: Molds can usually only simulate specific wound types or treatment steps, and cannot fully demonstrate the complexity and diversity of wound treatment. In addition, the operation of the mold may also be subject to certain limitations and cannot fully simulate the operation in the real scene.

[0007] 2. Disadvantages of Pictures as Teaching Tools

[0008] Limited information: Pictures usually only show static images of wounds and cannot provide a dynamic and comprehensive understanding of wound management. This may lead to students’ in-depth and incomplete understanding of wound management.

[0009] Lack of interactivity: As a teaching tool, pictures can usually only be viewed and learned passively by students, lacking interaction and feedback between students. This one-way teaching method may reduce students' learning interest and participation.

[0010] Slow update: Similar to molds, it is relatively difficult to update pictures. With the continuous development of medical technology, new wound treatment methods and concepts continue to emerge, but the speed of picture updates may not keep up with these changes.

[0011] Varying quality: The quality of teaching images may vary depending on the source, shooting technique, etc. Low-quality images may prevent students from clearly seeing the details and features of the wound, thus affecting learning outcomes.

[0012] Disadvantages of VR as a teaching tool

[0013] Technical limitations and equipment costs: VR technology requires high-performance hardware equipment and stable software systems to support it, which increases teaching costs.

[0014] The maintenance and updating of equipment is also a considerable expense, which may be a burden for educational institutions with limited resources.

[0015] User experience and adaptability: Wearing a VR helmet for a long time may cause discomfort to the user, such as dizziness, nausea, etc., which will affect the learning effect. Different users have different adaptability to VR devices, and some people may not be able to adapt well to this teaching method.

[0016] Lack of realism and emotional communication: Although VR technology can simulate realistic wound care scenarios, it still lacks realism and emotional communication compared to real patients in reality. This may cause students to feel unfamiliar or lack confidence when facing real patients.

[0017] Technology Updates and Compatibility: VR technology is developing rapidly, but there may be compatibility issues between VR devices of different brands and models. Summary of the invention

[0018] The technical problem to be solved by the present invention is that the existing wound teaching tools have defects, which affect the teaching quality.

[0019] In order to solve the above technical problems, the technical solution of the present invention is to provide a method for teaching wound care using injured fruits, comprising the following steps:

[0020] S1. Different types of fruits are classified according to their water content to simulate wounds with different exudates;

[0021] S2. Choose the appropriate dressing according to the water content of the fruit;

[0022] S3, treat the fruit to simulate different wound types;

[0023] S4, showing wound treatment steps on the treated fruit;

[0024] S5. Observe the changes in fruits after wound treatment to achieve teaching objectives.

[0025] Optionally, in step S2, for fruits with a water content of more than 92%, select a dressing with strong water absorption, for fruits with a water content of 85%-92%, select a dressing with medium water absorption; for fruits with a water content of 80%-85%, select a dressing with good air permeability.

[0026] Optionally, in step S3, the simulated wound type and the treatment of the fruit include:

[0027] Acute wound: a wound caused by external force in a short period of time;

[0028] Cuts: Use a knife to make cuts of varying depths and lengths on the surface of the fruit;

[0029] Contusion: simulate contusion through friction impact;

[0030] Puncture injuries: piercing the fruit with a sharp object;

[0031] Infected wounds: Use rotten fruit to simulate infected wounds;

[0032] Pressure damage: Long-term pressure causes different degrees of damage to the local appearance of the fruit;

[0033] Crushing injury: Crushing causes varying degrees of damage to the internal structure of the fruit.

[0034] Optionally, in step S4, the wound treatment step includes:

[0035] S41. Cleaning

[0036] Use clean water or disinfectant to gently wash the area around the fruit wound to remove impurities and contaminants;

[0037] S42, stop bleeding

[0038] For simulated cuts, demonstrate how to control bleeding;

[0039] S43, Exploring the Wound

[0040] Perform wound exploration when puncture wounds, cutting wounds or suspected deep tissue injuries are encountered;

[0041] S44. Disinfection

[0042] Disinfect the wound with disinfectant;

[0043] S45, Bandage

[0044] Use appropriate dressings to bandage the wound, simulate the bandaging process, and explain the purpose and precautions of bandaging.

[0045] In summary, the present invention uses injured fruits to teach wound care. This method simulates the process of human wound care and uses the "wounds" of fruits to demonstrate basic wound treatment principles and techniques, allowing clinical students to more intuitively understand wound injury conditions, exudate conditions, dressing selection and treatment principles, and provides another teaching idea. It improves the ability of flexible application in clinical practice, is low-cost, and is easy to update. The specific advantages are as follows:

[0046] 1. Physical display: Display different types of damaged fruits in class to allow students to intuitively feel the water content and texture of the fruit;

[0047] 2. On-site case analysis: The injured fruits on site can be used as independent cases to analyze the injury conditions, exudate conditions, dressing selection and treatment principles of different wounds;

[0048] 3. Practical operation: Let students use their brains to analyze and judge, and their hands to select dressings, simulate the treatment of wounds with different types of injuries and different exudates, and deepen their understanding and memory;

[0049] Through this method, students can not only better understand the basic principles and techniques of wound care, but also develop observation, analysis and problem-solving abilities in practice. At the same time, this method can also stimulate students' interest and enthusiasm in learning, making the teaching process more lively and interesting. DETAILED DESCRIPTION

[0050] The present invention is described in further detail below.

[0051] The present invention uses injured fruit as a teaching tool for wound care, and by simulating the process of human wound care, uses the "wounds" of fruit to demonstrate basic wound treatment principles and techniques. It is an intuitive and creative teaching method, and is particularly suitable for the training and teaching of wound specialist nurses in the field, and includes the following steps:

[0052] S1. Different types of fruits are classified according to their water content to simulate wounds with different exudates;

[0053] S2. Choose the appropriate dressing according to the water content of the fruit;

[0054] Specifically, fruits with a water content of more than 92%, such as watermelon, have a water content of 92%, which is equivalent to a large amount of exudate in the wound. For acute wounds such as burns and trauma, highly absorbent dressings should be selected, such as alginate dressings and foam dressings, to quickly absorb exudate and keep the wound dry;

[0055] Fruits with a water content of 85%-92%, such as strawberries, have a water content of 91%, which is equivalent to a moderate amount of exudate in the wound. For example, in chronic ulcers and eczema, you can choose dressings with moderate water absorption, such as some alginate dressings, thin foam dressings, calcium alginate, etc., which can absorb exudate and keep the wound moist to promote healing.

[0056] Fruits with a water content of 80%-85%, such as apples, have a water content of 85%, which is equivalent to less wound exudate. For superficial abrasions, minor burns, etc., you can choose dressings with good breathability, such as hydrocolloids, transparent dressings, ordinary gauze, etc., which can protect the wound and keep the skin around the wound dry and clean;

[0057] Fruits with a water content of more than 80% but containing certain acidic substances, such as oranges, are equivalent to moderate wound exudate, but containing certain acidic substances. For some infected wounds, you should choose dressings with antibacterial effects, such as silver dressings, which can absorb exudate, inhibit bacterial growth, and promote wound healing;

[0058] Other special fruits, such as tomatoes and bananas, are rich in water and contain a certain amount of juice. They can be compared to wounds with a moderate amount of slightly colored exudate. After the juice is removed, multiple cavities will appear. In teaching, emphasis can be placed on the assessment of the internal structure of the wound, such as cavities, the location and depth of the undermining, etc. For such wounds, it is necessary to select alginate dressings with strong absorption and insoluble properties, combined with the use of drainage dressings to fully absorb the exudate and keep the wound clean. In case of cavities, it is necessary to use dressings that can be stuffed to absorb the exudate.

[0059] The inside of a banana is relatively moist, but its texture is relatively sticky, which can be compared to a wound with sticky, difficult-to-absorb exudate. For this type of wound, you need to choose a dressing with strong absorbency and moisturizing properties, such as a hydrocolloid dressing containing moisturizing ingredients, which can keep the wound moist and effectively absorb the exudate.

[0060] For fruits without peel protection, such as strawberries, oily gauze dressings such as Vaseline should be used;

[0061] Fruits with necrotic or rotten flesh, such as some infected wounds, should use hydrogel dressings to remove the rotten flesh and combine them with antibacterial dressings, such as silver-containing dressings, which can absorb exudate and inhibit bacterial growth, thus promoting wound healing;

[0062] S3. Treat the fruit to simulate different wound types, including:

[0063] Acute wound: a wound caused by external force in a short period of time;

[0064] Cutting injuries: Use a knife to cut cuts of different depths and lengths on the surface of the fruit to simulate different types of cutting injuries;

[0065] Bruising: simulate bruising through friction and impact to observe the damage inside the fruit;

[0066] Puncture wounds: Piercing the fruit with a sharp object to simulate a penetrating wound;

[0067] Infected Wounds: Use rotten fruit to simulate an infected wound.

[0068] Pressure damage: Due to long-term pressure, the local appearance of the fruit will be damaged to varying degrees;

[0069] Squeezing injury: squeezing causes varying degrees of damage to the internal structure of the fruit;

[0070] When observing the internal conditions of fruits that have been subjected to compression deformation, they have certain similarities with pressure injuries of the skin in terms of causes, changes in appearance, prevention and treatment.

[0071] S4. Demonstrate wound treatment steps on the treated fruit, including:

[0072] S41. Cleaning

[0073] Use clean water or disinfectant to gently wash the area around the fruit wound to remove impurities and contaminants;

[0074] S42, stop bleeding

[0075] For simulated cuts, show how to control bleeding (although the fruit doesn't actually bleed, the principle of hemostasis can be explained);

[0076] S43, Exploring the Wound

[0077] Wound exploration should be performed when puncture wounds, cuts or deep tissue injuries are suspected;

[0078] S44. Disinfection

[0079] Use disinfectants to disinfect the wound, such as diluted bleach or alcohol, but be careful to avoid using strong corrosive substances that are harmful to fruits. Detect infected wounds early and treat them in time;

[0080] S45, Bandage

[0081] Use appropriate dressing materials to bandage wounds, simulate the bandaging process, and explain the purpose and precautions of bandaging;

[0082] S5. Observe the changes in fruits after wound treatment to achieve teaching objectives.

[0083] Through this approach, students can not only better understand the basic principles and techniques of wound care, but also develop observation, analysis and problem-solving skills in practice. Using injured fruits and wounds as a comparison can not only help improve students' understanding and memory, but also stimulate their interest and enthusiasm in the field of wound care, but also remind students of the differences between fruit wounds and human wounds, ensuring that they understand the practical application scope of the knowledge they have learned.

[0084] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
