1 to 4, the body organ simulator according to the present invention includes a lower mold 10, an upper mold 20, and an inner mold 30.

First, the upper side of the lower mold 10 is opened to form an internal groove 17 corresponding to the external shape of the body organ, and the internal groove 17 is penetrated downward to form an injection hole 11 through which the hardener is injected. do. Here, the external shape refers to the shape of the outer surface of the body organ.

The upper mold 20 is coupled to the upper part of the lower mold 10, closes the upper part of the internal groove 17, and has an discharge hole 21 through which the internal air is discharged by the curing agent injected into the injection hole 11. is formed

The internal mold 30 is provided inside the internal groove 17 and is spaced apart from the internal groove 17 to form a molding space 31, and is formed to correspond to the inner shape of the body organ. Here, the endotype refers to the shape of the empty space inside the body organ.

At this time, the curing agent injected into the injection hole 11 fills the molding space 31, and at the same time, the air inside the molding space 31 is discharged through the discharge hole 21 by the curing agent filled in the molding space 31. It is discharged to the top through.

By pushing and filling the hardener from the bottom to the top, the molding space 31 can be filled with the hardener without any empty space. At this time, the curing agent may be made of silicone, but is not limited thereto.

Additionally, the molding space 31 can be formed to correspond to the thickness of the body organ.

When the hardener filled in the molding space 31 is molded, the lower mold 10 and the inner mold 30 are sequentially separated from the upper mold 20 to correspond to the outer shape of the body organ, and the inside is empty and the inner shape of the body organ is formed. It is possible to create a model of a body organ that corresponds to

Here, the body organ model can be made of body organs such as the heart and stomach depending on the shape of the mold.

In order to manufacture a body organ model with a complex internal structure, such as the heart, it is difficult to remove the internal mold 30.

Accordingly, as shown in FIG. 5, the internal mold 30 includes a split mold 34 divided into at least two parts so that it can be easily separated from the body organ model.

For example, in the case of the heart, the atrium, aorta, and pulmonary artery are connected to the ventricle as one, making the demolding process of the internal mold 30 from the molded body organ model impossible or very difficult.

Accordingly, the internal mold 30 is manufactured by dividing it into a plurality of split molds 34, the plurality of split molds 34 are combined, a body organ model is molded, and then the split molds 34 are separated one by one. You can.

In addition, dividing the plurality of split molds 34 so that they can be easily separated from each other and demolded from the molded body organ model may vary depending on the structure and division direction of the body organ to be molded. .

In addition, the split mold 34 is formed with a connecting portion 35 so that it can be connected to another split mold 34. That is, the connection portion 35 is a divided surface of the split mold 34 and is a connected surface.

Referring to FIGS. 6 to 9, the connecting portion 35 of the split mold 34 is formed with a protruding connecting core 36.

The connection part 35 of another split mold 34 connected to the connection part 35 of the split mold 34 is formed to correspond to the connection core 36 and is connected so that the connection core 36 can be inserted and coupled. A connecting core groove 36a into which the core 36 is inserted is formed.

Here, the connection core 36 and the connection core groove 36a are each provided with a magnetic material, which will be described later, but are connected by magnetism, which may cause slight shaking and rotation. To prevent this, the connection core 36 is formed to protrude into a polyhedron. For example, the connecting core 36 may be formed as a square pillar or a hexagonal pillar.

In addition, if the protrusion length of the connecting core 36 is too long, the connecting core 36 may be broken when the internal mold 30 is demolded, and excessive force may be applied, causing the body organ model to be torn. In order to prevent this, it is desirable to limit the protrusion length of the connecting core 36 to a maximum of 5 mm.

In addition, the connecting core 36 is formed as a polyhedron, and extends in the longitudinal direction of the connecting portion 35 to form a more protruding extended core 37. And the connection core groove (36a) is further formed with an extension core groove (37a) to correspond to the extension core (37).

For example, the extension core 37 is formed to protrude further by extending the outer surface of the polyhedral connecting core 36 in the outward direction. Through this, shaking and twisting of the connected split mold 34 can be prevented.

In addition, the connecting portion 35 of the split mold 34 has an auxiliary core 38 protruding around the connecting core 36, and the connecting portion 35 of another split mold 34 has an auxiliary core ( 38), and an auxiliary core groove 38a into which the auxiliary core 38 is inserted is formed.

The purpose of forming the extension core 37 and the auxiliary core 38 is to easily align and connect the connection direction of the split mold 34 when the connection portion 35 of the split mold 34 is large or is formed long in one direction. This is to prevent twisting in areas where the core 36 is not formed.

At this time, a plurality of connecting cores 36 can be formed in the connecting portion 35, but it is difficult to separate the split mold 34 connected to the multiple connecting cores 36.

In other words, the connecting core 36 serves to maintain the center, and the extension core 37 and auxiliary core 38 are additionally needed for auxiliary direction and fixation.

And, to facilitate connecting and fixing the split molds 34 to each other and separating them, the auxiliary core 38 has an area smaller than the area of the connecting core 36 and a protruding length smaller than the protruding length of the connecting core 36. It is preferable to be formed, but it is not limited to this.

Additionally, the auxiliary core 38 may be formed in a hemispherical shape so that it can be easily separated from the auxiliary core groove 38a when twisted or shaken with a small force when separating the split mold 34, but is not limited to this. No.

At this time, in separating the connecting portion 35 where the connecting core 36 and the auxiliary core 38 are formed, the hemispherical auxiliary core 38 is first separated, and then the connecting core 36 is expanded due to the soft nature of the body organ model. ) can be separated.

Therefore, if the auxiliary core 38 is formed in the same size and shape as the connecting core 36, the soft body organ model may be torn, but as it is formed in different sizes and shapes, tearing is prevented and the split mold 34 is formed. can be separated more easily.

Here, a connecting core 36 and an auxiliary core groove 38a may be formed in the connecting portion 35, and a connecting core 36 and an auxiliary core 38 may be formed.
