Description

Animal models for veterinary and medical practice

This work is related to the field of engineering, especially medical engineering and veterinary engineering, and more especially to animal models used in veterinary and medical practice.

During the practice of veterinary science, animal care, veterinary technology, human nursing and human physician courses for college students and among educators in veterinary medicine, veterinary nursing, veterinary technology, human medicine and human nursing, a wide variety of clinical skills must be demonstrated and practiced in order to examine and treat animals and humans. Some examples of clinical skills practice are as follows: 1. Blood sample collection; 2. Intravenous puncture to provide fluids (physiological saline) and intravenous injections; 3. Intramuscular injection training; 4. Ear cleaning practice; 5. Pulse palpation; 6. Insertion of a thermometer to measure body temperature; 7. Endotracheal intubation and general anesthesia; 8. Nasopharyngeal intubation; 9. Upper airway endoscopy Training in veterinary science, animal care, veterinary technology, human medicine, and human nursing involves the demonstration and practice of clinical skills in a laboratory setting with live animals such as dogs or cats. However, there are some disadvantages and challenges to this approach, including:

1. The presence of many students in such demonstrations and exercises makes it impractical to adequately prepare experimental animals or provide real patient interactions (with humans) for each student. Therefore, it is not possible to prepare enough experimental animals for all students, making it infeasible for students to practice clinical skills. This may result in some people lacking expertise when actual physical examinations and treatments are required.

2. In addition, experimental animals or patients (humans) used for clinical skills training may suffer pain and discomfort due to clinical skills training. The owners of experimental animals may also worry about the welfare of animals and patients.

Efforts have been made to reduce these problems by producing three-dimensional models that replicate animal (including human) organs, intended as teaching and practice aids, and for use in veterinary and medical practice, including three-dimensional models for each individual organ, as well as three-dimensional full-body models of animals or humans. These models are primarily made using synthetic materials such as resins, fiberglass, and/or silicone.

However, there are limitations. First, most current 3D models focus on showing various body parts, which is very limited if they are 3D models used to practice clinical skills. These 3D models can only help practice a very narrow range of clinical skills, perhaps only one or two. Therefore, the use of 3D models for teaching and practicing veterinary clinical skills is not effective.

Second, existing materials used for 3D modeling lack the elasticity and lifelike softness of actual animal or human skin, including the surfaces of various organs.

Third, the materials used are synthetic rather than natural.

Fourth, these materials need to be imported from abroad and are expensive.

The purpose of this creation is to overcome the above-mentioned shortcomings of the known technology by providing a virtual animal model for veterinary and medical practice, which has a size very similar to that of a real animal and integrates the basic internal organs in a body frame, which enables the practice of various clinical skills.

An animal model for veterinary and medical practice, comprising a set of internal organs and a body frame, wherein the set of internal organs is placed in the body frame, wherein the set of internal organs in the animal model comprises internal organs including lungs, stomach and a set of urinary and reproductive organs, wherein each internal organ is connected to each other and wrapped with para rubber.

The body frame includes a head and neck, a body, and a foot that are connected to each other. In the body frame, the head and neck include ears, a nose with a nasal cavity, a mouth with an oral cavity, a pharyngeal structure, a trachea, and an esophagus, wherein the nasal cavity and the oral cavity are connected to the pharyngeal structure, the trachea, and the esophagus, wherein the other end of the trachea is connected to the lungs, and the other end of the esophagus is connected to the stomach. The body includes an internal space, which includes a thoracic cavity, an abdominal cavity, and a pelvic cavity for supporting internal organs. The legs support the head and neck and the body, wherein the legs include at least two legs, wherein the animal model used for veterinary and medical practice is mainly made of natural rubber, wherein the preferred natural rubber is para rubber.

The purpose of this creation is to provide an animal model for veterinary and medical practice that is capable of practicing important clinical skills through at least three openings. If clinical skills practice is desired for each opening or all three openings together, this can also be done, including from the head and neck through the mouth, medical instruments can be inserted from the mouth to the lungs placed in the chest cavity or the stomach placed in the abdominal cavity, from the nose, medical instruments can be inserted into the lungs or stomach within the body frame, and medical instruments can be inserted from the opening of the male urinary organs through the bladder placed in the pelvic cavity.

Another purpose of this invention is to provide animal models for veterinary and medical practice made of natural rubber, especially para rubber. Thailand is a source of raw materials and an important source of para rubber in the world, which enables the animal model to have a contact surface close to real animal skin and in contact with the main material, which is cheap para rubber; therefore, the production cost of animal models for veterinary and medical practice is also reduced.

Another purpose of this invention is to provide an animal model for veterinary and medical training made of natural rubber, especially para rubber, which can practice a variety of clinical skills, including: - tracheal intubation and general anesthesia; - endoscopic intubation of the upper gastrointestinal tract; - nasogastric intubation; - nasopharyngeal intubation: - endoscopic intubation of the upper respiratory tract; - male catheterization; - inserting a mercury thermometer in the anus to measure body temperature; - intramuscular injection; - ear cleaning practice; - blood sampling from the front legs; - blood sampling from the hind legs; - blood sampling from the neck back area; - pulse palpation in the inguinal area; - blood sampling from the front legs; - resuscitation of sick animals.

Another purpose of this creation is to provide an animal model for veterinary and medical training, which can practice a variety of clinical skills of veterinarians and has a contact surface close to real animal skin.

Another purpose of this creation is to provide animal models for veterinary and medical practice, so as to more effectively teach and practice veterinary and pharmaceutical clinical skills and reduce the use of real animals or humans. This is very beneficial to the field of veterinary education, training veterinarians, doctors (humans) and related personnel to practice veterinary and pharmaceutical clinical skills, and further provide assistance for human diagnosis and treatment.

The concept of this creation can also be applied to mannequins made of para rubber for medical training.

Other advantages of this creation are shown in the detailed description of this creation.
