JP7262361B2 - Balloon model for teaching anatomy - Google Patents

Description

TECHNICAL FIELD The present invention relates to an anatomy educational balloon model that simulates various parts of the body and is used for informed consent in, for example, medical practice.

Conventionally, regarding medical practice, so-called informed consent, in which the patient agrees after receiving sufficient explanation about the patient's medical condition, the purpose of treatment, the treatment method, and the expected results, etc., has been emphasized even in the medical field. It is In response to this, doctors often give informed consent to patients at medical sites using non-expandable medical models made of wood, plastic, or the like of eyeballs, organs, or the like.

Regarding this type of model, for example, Patent Document 1 discloses a crystalline lens model incorporated in an eyeball model that can be disassembled and assembled. The intraocular lens model is inserted into the incision through the incision, and the incision is closed so that the intraocular lens model can be freely worn in the same manner as the human crystalline lens. A crystalline lens model is disclosed.

Real Kaihei 5-96865

However, the device disclosed in Patent Document 1 is not configured to be freely inflatable and contractible, so when a doctor explains a case to a patient at a medical site, the device is inflated to a larger size, so that the patient can explain to his/her family. I couldn't shrink it down to make it smaller when I took it home. In addition, it was not assumed to present the names of each part of the eyeball to the patient, or to mark the surface of the model to identify the affected part.

The present invention has been made in view of such problems, and the object thereof is to expand and contract freely, and when a doctor or the like explains a case to a patient, the patient can take it home by inflating it to a larger size. To provide a balloon model for teaching anatomy suitable for informed consent or the like, which can be contracted to be small in size to make it easy to carry.

In addition, in the education of medicine, dentistry, pharmacy, etc., anatomy is suitable for helping students to understand organs and body composition three-dimensionally at all times by carrying it to classes, etc., inflating it, deflating it, and transporting it easily. It is also to provide a balloon model for teaching materials.

In order to solve the above problems, an anatomy teaching balloon model according to one aspect of the present invention comprises a hollow main body molded in the shape of a living organ or a composition, and a part of the main body having and an air supply unit connected to the main body, wherein the state of the organ or the composition and characters representing the names of each part of the organ or the composition are printed on the surface of the main body. Air is supplied to the part through the air supply part, and the body part is composed of a main part and a plurality of sub-parts divided by medical units, and each of the sub-parts is detachable from the main part. There is.

According to the present invention, it can be freely inflated and contracted, and when a doctor or the like explains a case to a patient, it is inflated to make it larger, and when the patient takes it home, it is contracted to make it smaller to make it easier to carry. It is possible to provide a balloon model for teaching anatomy that is suitable for formed consent or the like.

In addition, in the education of medicine, dentistry, pharmacy, etc., anatomy is suitable for helping students to understand organs and body composition three-dimensionally at all times by carrying it to classes, etc., inflating it, deflating it, and transporting it easily. It is also to provide a balloon model for teaching materials.
