Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a biological simulator for measuring proficiency in handling medical devices and the like, and more particularly, in a biological simulator having a mucosal structure, a colonoscope, a gastroscope, a duodenoscope, and an airway securing device The present invention relates to a biological simulator for practicing tubes, laryngoscopes, etc. and measuring their proficiency.
[0002]
[Prior art]
It has been common practice to practice the handling of medical devices using practice models such as colonoscopy, gastroscope, duodenoscope, airway securing tube, laryngoscope, etc. Is being done. However, conventional practice simulators are made of only one layer of synthetic resin in order to reproduce the flexibility of the mucosa, and the reproduction of the mucosa is insufficient. The endotracheal intubation, such as the mucosa, in the case of performing the handling of such medical devices, there is a case where scratch the damage and mucous membranes of the mucous membranes due to immaturity of the technology, in the conventional simulator handling of such such medical devices Since the function to reproduce the mucosal smear mark or the mucosal slide feel was insufficient, the post-verification of the procedure performed by the surgeon could not be performed, or the procedure was not I couldn't train for accuracy. Also, since mucosal flexibility and sliding feel were not reproduced, the conventional simulator had little realism and could not perform simulation training that maximized the operator's tension.
[0003]
[Problems to be solved by the invention]
Therefore, the present inventor should provide a living body simulator that makes it possible to educate the operator in pursuit of the accuracy of the technique during training while making the operator feel the realism more than the conventional simulator and maximizing the tension of the operator. As a result of various studies, the present invention has been completed, and an object of the present invention is to provide a biological simulator that can pursue the accuracy of a technique during training and can know the results of the education. .
[0004]
[Means for Solving the Problems]
SUMMARY of the present invention, in a biological simulator, a layer part is provided with a synthetic resin surface treatment agent layer such as scarred by handling of the instrument or the like through the release agent layer on one surface of synthetic resin layer corresponding to the mucosa It is a biological simulator characterized by a structure.
And it is preferable that the layer structure which consists of the said synthetic resin layer and a peeling layer laminates | stacks the synthetic resin layer on the at least one surface of the synthetic resin gel layer through the releasing agent layer.
That is, in the present invention, the portion corresponding to the mucous membrane of the biological simulator has a layer structure composed of a synthetic resin layer and a release agent layer, so that it has flexibility like a mucous membrane. mirror, duodenum endoscope, verifying the trace of mucosal damage by the medical device it is possible to acquire the slide feel mucosa when for airway Chupu, medical tools laryngoscope like is inserted You can know the skill level of the technique.
That is, the flexibility of the mucous membrane structure of the human body is reproduced with a synthetic resin and a release agent, and the surface of the mucous membrane is subjected to surface treatment so as to leave a scar due to the handling of a medical device such as an intubation tube, that is, the surface of the synthetic resin. It is a biological simulator provided with a treatment agent layer.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail.
The biological simulator of the present invention is not particularly limited, but can be applied to an airway management model throat replacement type simulator manufactured by Koken Co., Ltd., an airway management trainer manufactured by Laerdal, or an endotracheal intubation practice model manufactured by Ambu. Also, for example, when applied to the Koken Airway Management Model pharyngeal exchange type simulator, that is, when attached to the laryngeal part of the Koken Airway Management Model and the surrounding mucosa, the operator at the time of laryngeal deployment or insertion of the tracheal intubation tube According to the procedure performed, post-verification can be made based on whether or not the tube is damaged by inserting the tube on the mucous membrane, and education for pursuing the accuracy of the procedure can be made possible.
Also, by reproducing the mucous membrane flexibility and the slide feel, it is possible to reproduce a sense of reality that could not be reproduced by a conventional simulator, and to create a model that can perform a simulation exercise that maximizes the operator's tension. In addition, the laryngeal part and the surrounding mucous membrane part can be exchanged, and the individual can have the parts, allowing post-verification of his / her procedure.
[0006]
In the present invention, the synthetic resin constituting the mucosal structure is flexible and reproduces mucosal flexibility and slide feel, for example, peeled off at least one surface of the synthetic resin gel layer. A synthetic resin layer is preferably provided via an agent layer , or a synthetic resin layer provided on both sides of a synthetic resin gel layer via a release agent layer is preferred. The material of the synthetic resin gel layer may be any of silicone, vinyl chloride or urethane, and the thickness is about 3 mm. If the thickness is 5 mm or more, the elasticity is too high. Disappear. A synthetic resin layer is provided on at least one surface of the synthetic resin gel via a release agent layer. Release agent layer and the fluorine-based is, a silicone-based vinyl chloride or urethane release agent, showing the effect of sliding resistance of the surface by passing through the release agent. The material of the synthetic resin layer provided on the release agent layer may be any of silicone, vinyl chloride or urethane, and its thickness is about 0.4 mm, and the elasticity of the gel layer is 0.4 mm or more. The strength of the layer is lost at 0.1 m or less.
Further, in the biological simulator according to the present invention, a synthetic resin surface treatment agent layer is provided on one surface of the synthetic resin layer constituting the mucosal structure via a release agent layer, thereby leaving a trajectory due to handling of the instrument, etc. It is preferable because the effect of pursuing the accuracy of can be obtained. Synthetic Examples of the resin surface treatment agent Ricoh down system, vinyl chloride, or it is preferable to use a urethane-based agent.

An example of the mucosal structure part of the biological simulator according to the present invention is shown in FIG. In FIG. 1, a release agent layer 3 is laminated on both sides of a synthetic resin gel layer 1 and a synthetic resin layer 2 is provided on the release agent layer 3. A treatment agent layer 4 is provided.
For example, the larynx of an airway management model is configured so that the synthetic resin surface treatment agent layer 4 having such a mucosal structure becomes the surface.

【Example】
Hereinafter, the present invention will be specifically described with reference to examples.
Example 1
The biological simulator according to the present invention was manufactured by the following procedure.
1. The inside made of synthetic resin is made with silicone rubber using a special mold. Using a special type that is a female type, pour silicone rubber raw material, spread it uniformly, and then crosslink to create a skin.
The outer surface of the leather prepared in 2.1 is coated with a fluororesin release layer to form an intermediate layer.
3. Separately, the outermost film is made of silicone rubber.
Apply a fluororesin to the inner surface of the outermost layer created in 4.3 to create a release layer.
The intermediate layer prepared in 2 is set in the film prepared in 5.4, and a silicone gel is injected into the space formed between the film and the intermediate layer to create a gel layer.
A release layer is prepared by applying a fluororesin to the inner surface of the cylindrical structure in which the film, gel layer, and intermediate layer prepared in 6.5 are integrated.
Further, a mixture of silicone rubber and silicone gel is applied to the inner surface of the cylindrical object on which the release layer is formed, and a synthetic resin surface treatment agent layer is provided on the innermost surface to leave a trace of handling of instruments and the like.
