Abstract

PROBLEM TO BE SOLVED: To make learnable the feeling of each operation, such as, practical insertion of a tube into a trachea, use of laryngeal mask, and use of a gullet closing airway by forming this model by arranging a lower teeth row spaced from the lower jaw-bone, and supporting the lower teeth row by an elastic column in this space. SOLUTION: An upper teeth row 4 is fixed to the lower edge part of a skull 1, and a lower teeth row 5 opposed thereto is arranged to be supported by an elastic column 8 projected from the tip part of the lower jaw-bone part 2, and a space 7 is formed between the lower teeth row 5 and the lower jaw- bone 2. The middle part of the lower teeth row 5 is filled with a tongue member 9, and the lower end of this tongue member 9 is fixedly adhered to the lower jaw-bone 2. The tongue member 9 extandable and retractable and is formed so as to be pulled out up to the outside of the buccal cavity part. And, at the time of practice, the buccal cavity is made open by holding down the lower teeth row 5. Thus, by holding the lower teeth row 5 downward, the column 8 arranged under the lower teeth row 5 is bent to be made open in mouth, so that a tube can be inserted into the larynx in a case of an air tube insertion.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to learning the operation of securing a respiratory tract such as wearing a laryngeal mask, an esophageal closed airway, an esophagogastric tube airway, endotracheal intubation and nasal intubation for a person in a state of asphyxia. On a simulation model for airway securing training to be used for training.

[0002]

2. Description of the Related Art A training model for performing training for resuscitation by inserting a tube into a trachea of a person in a state of asphyxia has been known before the present application. However, many of the traditional training models are upper jaw, lower jaw,
The members such as the tongue and the entrance to the trachea move independently of each other, resulting in a different sensation from the case of actually performing the operation. Therefore, the training model was not always satisfactory. A training model in which this point is improved is disclosed in Japanese Patent Publication No. 3-31269. The simulation model disclosed in this publication consists of a funnel-shaped (funnel-shaped) member in which the oral cavity and throat of the head are made of a highly elastic material, and a convex tongue member is provided at the front upper edge of this member. In front of the tongue member is mounted inside the movable lower jaw, the trailing edge of the funnel-shaped member is mounted below the skull, and the lower part of the funnel-shaped member has a substantially circular cross-section. And a front duct connected to one end of the non-collab jibble tube and hinged at the other end to the support, and a rear duct having a substantially elliptical cross-sectional shape. Further comprising a flap extending from the inner surface of the funnel-like member and having the same shape as the epiglottis provided in the area adjacent to the entrance of the front duct, for performing intubation into the trachea. It is a simulator. However, this simulator moves the lower jaw to open the mouth and inserts the tube into the trachea. However, this operation is difficult, and if it is forcibly opened, the corner of the mouth of the elastomer cover may tear to the side.

[0003]

Therefore, this point has been improved and the use of a laryngeal mask, the use of a closed esophageal airway, the use of an esophagogastric tube airway, or the use of a more practical tracheal intubation has been improved. As a result of various investigations on a simulation model that can acquire the sensation of operation such as nasal intubation or finger crossing method to widely open the mouth of the patient or check for the presence of secretions in the oral cavity, the present invention was completed. An object of the present invention is to provide an airway securing training simulation model capable of acquiring the sensations of the above operations.

[0004]

The gist of the present invention is to provide an airway securing training simulation model comprising a skull, and a mannequin head in which each part of a larynx having a mandible including the mandible and a trachea is covered with an elastic material. The upper dentition is fixed to the lower edge of the skull, the lower dentition is provided apart from the mandible by a space, and an elastic column supporting the lower dentition is provided in the space. It is a simulation model.

That is, according to the present invention, the lower dentition is provided with a space from the mandible, and the lower dentition is supported in the space by an elastic support. The column supporting the column bends and opens the mouth to perform each of the above operations.When the pressing force is released, the column returns to its original state, and the corner of the elastic material covering the head is torn. There is nothing.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The elastic material covering the head in the present invention is polyvinyl chloride, silicone rubber, or the like. The use of silicone rubber is preferred because it gives an actual feel. The elastic support used in the present invention can be used as long as it is made of an elastic material having a repulsive force, such as a spring, as well as the above-mentioned elastic material. In addition, a tongue member may be provided in a part of the space of the lower jaw. In this case, it is preferable to use silicone rubber as the tongue member. As a method of providing the column of the lower dentition, the column may be protruded from the tip of the lower jaw, or may be protruded from the side portion, and it is only necessary to be able to hold the lower dentition in the space. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a simulation model according to the present invention,
An oral cavity is formed by a skull 1 and a mandibular bone 2 movable about a point 6 provided on the skull 1 as a fulcrum. The back of the oral cavity is connected to a trachea 3 and comprises a larynx. The upper dentition 4 is fixed to the lower edge of the skull 1, and the lower dentition 5 opposed thereto is
A space 7 is formed between the lower dentition 5 and the lower jaw 2 by being supported by an elastic column 8 protruding from the distal end of the lower jaw 2. The central portion of the lower tooth row 5 is filled with a tongue member 9, and the lower end of the tongue member 9 is fixed to the mandible 2. The tongue member 9 has elasticity so that it can be pulled out of the oral cavity.

[0008] Thus, in practice using the simulation of the present invention, the lower dentition 5 is pressed down to open the oral cavity. In the simulation of the present invention, by holding down the lower dentition and lowering it, the support provided below the lower dentition is bent and the mouth is opened, and in the case of tracheal insertion, the tube can be inserted into the larynx. it can. Note that the same applies to the case where the column is protruded from the side surface. By releasing the lowering force, the elastic strut returns to its original position, closing the lower dentition and closing the mouth.

[0009]

As described above, in the simulation model of the present invention, the space is provided below the lower dentition, and the lower dentition is supported by the elastic support. Therefore, when the lower dentition is pressed, the support is bent. The mouth can be opened and the tube can be inserted into the trachea, and the mouth corner of the elastic material covering the head does not tear as in the conventional simulation model. If it is made of a certain material, you can experience the feeling of inserting the tube into the actual trachea.
