Description

Technical Field

[0001] The present invention relates to a medical model, and particularly to a human respiratory tract model for demonstrating inhalation injury. Background Art

[0002] Inhalation injury refers to the burns of the nasopharynx, trachea, bronchi and even the lungs caused by inhaling high-temperature gases, flames or chemical substances into the respiratory tract, or by accidentally drinking boiling water, etc.

[0003] Inhalation injury is one of the acute diseases in clinical practice, with relatively high morbidity and mortality rates. Especially in recent years, with the improvement of burn treatment technologies and means, the number of deaths caused by shock and infection in the early stage has gradually decreased, while organ dysfunction and even failure caused by various reasons have become the main causes of death in burns. Among them, respiratory insufficiency caused by inhalation injury ranks first among various types of organ dysfunctions. Therefore, the basic and clinical research on inhalation injury is one of the hotspots in the current research field of burns. The accurate and rapid judgment of the condition of inhalation injury patients determines the next comprehensive treatment of the patient's overall condition, and is a prerequisite for improving the success rate and quality of treatment of inhalation injury patients, which is crucial in clinical practice. Therefore, the teaching of the judgment of inhalation injury is also the basis for the teaching of knowledge related to inhalation injury. The pathophysiological characteristics and the teaching of the degree of injury of inhalation injury are important basic contents in the judgment of burn injuries. However, in the traditional teaching of inhalation injury, only lectures with words and pictures are used, and the teaching process is relatively abstract, which is not conducive to students' intuitive mastery of knowledge related to inhalation injury. In clinical practice, experienced doctors often focus on the development of clinical treatment work in the early treatment process and cannot specifically and systematically teach theoretical knowledge to students. All of the above are not conducive to the cultivation of medical talents with professional knowledge of burns.

[0004] To solve the problem of the abstract and obscure learning of inhalation injury knowledge and improve the teaching quality, the development and use of a reasonable medical model is one of the more practical and efficient methods. However, there is currently no special teaching model for inhalation injury, especially for the degree of inhalation injury. Based on this, we intend to invent a human respiratory tract model for demonstrating inhalation injury. Summary of the Invention

It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0032] Although exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence.

The human respiratory tract model includes a prosthetic human body. The prosthetic human body includes a prosthetic head, a prosthetic neck, and a prosthetic upper torso. The prosthetic head, the prosthetic neck, and the prosthetic upper torso can be integrally formed. Alternatively, the prosthetic head, the prosthetic neck, and the prosthetic upper torso can be separately formed and connected together in a detachable manner (such as magnetic attraction, bonding, screw connection, snap connection, shape fit) or a non-detachable manner.

[0034] The prosthetic human body can present one or more of the simulated human respiratory tract organs such as a simulated nose, a simulated oral cavity, a simulated pharynx, a simulated larynx, a simulated trachea, a simulated bronchus, a simulated small airway, and a simulated lung. It should be understood that in other embodiments, the prosthetic human body may also present other simulated human organs, such as a simulated tongue, simulated vocal cords, a simulated esophagus, etc. The human respiratory tract model can be made according to the actual size of a real person, or made by reducing or enlarging proportionally with reference to the size of a real person. In some embodiments, the human respiratory tract model can exaggerate or reduce the proportion of a certain part of one or more of the prosthetic head, the prosthetic neck, and the prosthetic upper torso according to the actual needs.

The human respiratory tract model may further include a covering. The covering is formed separately from the prosthetic human body and is complementary in shape to the longitudinal cross-section. The covering can cover the longitudinal cross-section to simulate the outer surface of the human body. The longitudinal cross-section and the covering can be connected together by magnetic attraction, snap connection, re-adhesive bonding, shape fitting, etc. The longitudinal cross-section may be in the form of a smooth straight surface or an arc surface, or may be in a stepped shape.

The transverse cross-section is configured to divide the prosthetic human body into two parts removably connected together, and the transverse cross-section is used to show the morphology at the cross-section of the respiratory tract, for example, including one or more of color, pattern, shape, and hardness. When cutting is performed at multiple locations in the human respiratory tract model along a direction substantially transverse to the respiratory tract, the prosthetic human body is divided into more parts.
