[Industrial applications]

 The present invention relates to a gynecologic diagnosis training model in which the model uterus can take various forms and enables diagnosis training in a wide range of cases.

[0002]

[Prior Art]

 In medical education related to obstetrics and gynecology, education of midwives, etc., it is essential to accurately grasp local findings by palpation or internal examination of the abdomen. However, it is extremely difficult to conduct education and practical training for students while examining patients in the clinical setting because it involves human rights of patients. Therefore, it has been practiced to provide the education and training by using a medical model related to obstetrics and gynecology. However, the conventional model is a model of human body anatomy of an adult woman, or a model made of a hard material, which is far from the softness of the human body. It was impossible to practice such as. The abnormal model was also for a specific case, so its contents were limited and comparison with the normal form was impossible.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a gynecological diagnosis training model that can improve the above-mentioned drawbacks and use a material similar to a living body, such as a simulated epidermis, a subcutaneous tissue, and a simulated pelvis, for practicing abdominal palpation and internal examination. is there.

[0004]

[Means for Solving the Problems]

 The gist of the present invention is a model substrate equipped with a soft epidermis member, a subcutaneous member made of a soft foam having a shape imitating the subcutaneous tissue of a female lumbar region, and a hard skeleton member having a shape imitating a female lumbar skeleton. A gynecological diagnostic training model consisting of a soft and elastic genital model imitating the uterus, fallopian tube, and ovary, in which at least one of the uterine part, fallopian tube part, and ovarian part corresponds to normal or abnormal. The gynecological diagnosis training model is characterized by being capable of taking a plurality of forms and being capable of being locked and disengaged from the model base body at a predetermined position corresponding to a living body. In other words, the present invention uses a replaceable model of a normal or abnormal reproductive organ model composed of materials and structures similar to those of a living body, which enables palpation from the abdomen, and by exchanging the normal and abnormal model. This enabled effective practice of gynecological diagnosis by palpating the abdomen of the internal examination. Furthermore, if the abnormal genital model is a flexible, elastic, and large variable bag, it can take multiple forms corresponding to the abnormal state by changing its air volume. This makes it possible to create various simulated cases, and as a result, the practical training effect can be further enhanced. Hereinafter, the present invention will be described in detail with reference to the drawings. In FIG. 1, a model substrate 1 is a model including an epidermis member 2, a subcutaneous member 3 and a skeleton member 4 and imitating internal and external tissues of a female waist as a whole. The model base 1 includes at least a tissue consisting of a female lower abdomen, external genitalia, vagina and dorsal side, and an abdominal part 7 is formed therein.

The skin member 2 envelops the subcutaneous member 3 and gives a feel similar to that of a living skin, and therefore is made of a soft material, for example, (a) olefin rubber such as ethylene / propylene rubber, low density polyethylene, or soft poly. Films or sheets made of rubbers with moderate elasticity such as acrylic rubbers such as vinyl chloride and acrylic acid ester copolymers, polyurethane rubbers, silicone rubbers and soft synthetic resins, and (b) woven cloth , Knitted fabric, non-woven fabric, etc. are made of stretchable fabrics, etc., which are impregnated with synthetic rubbers, soft synthetic resins, etc.

The subcutaneous member 3 imitates the shape of the subcutaneous tissue of the female lumbar region including at least the lower abdomen, external genitalia, vagina and dorsal region. The vaginal portion 6 of the subcutaneous member 3 has a communicating portion 6a with the abdominal cavity 7 so that the replacement model body 5 can be freely locked and released at a predetermined position.

Subcutaneous member 3 is made of a soft foam such as polyurethane foam or foam rubber to give a feel similar to the subcutaneous tissue of female lumbar region.

The skeleton member 4 imitates a female lumbar skeleton including at least the pelvis and the pubis, and is embedded in the subcutaneous member 3. The material can be selected from hard materials such as wood, metal and synthetic resins (for example, ABS resin, high density polyethylene, polypropylene, hard polyvinyl chloride, hard urethane resin, polysiloxane, etc.).

As shown in FIG. 1, the skeleton member 4 can be configured by separating it into constituent bones similar to a biological skeleton, or can be a part or the whole thereof integrated.

The genital model 5 gives a hardness and a touch that are similar to those of normal tissue as a whole, and therefore is made of a soft and elastic material such as an olefin rubber such as ethylene / propylene rubber or a copolymer of acrylate ester. It is made of rubber such as acrylic rubber, polyurethane rubber, and silicone rubber.

The genital organ model 5 is composed of a uterine part 5a, a fallopian tube part 5b and an ovarian part 5c, and at least one of them can take a plurality of forms corresponding to normal or abnormal (ie pathological symptoms). As the abnormal form, for example, as shown in FIGS. 2 and 3, at least one of the uterine portion 5a, the fallopian tube portion 5b, and the ovary portion 5c is enlarged. Fig. 2-1 shows normal, Fig. 2-2 and Fig. 2-3 show uterine fibroids (hypertrophy 5a ', 5a "), and Fig. 3-1 shows hypertrophy of right oviduct 5b' (eg, bleb). Fig. 3-2 shows hypertrophy of the left ovary 5c '(for example, ovarian edema). Abnormalities generally range from ping-pong ball size to neonatal head size. With respect to the fallopian tube part 5b and the ovarian part 5c, which have a pair, respectively, either the left or right side or the left or right side can be appropriately selected according to the case.

The reproductive organ model 5 of the present invention, which can take a plurality of forms corresponding to normal and abnormal, is provided with a pump 9 for sending fluid such as air and water for abnormalities accompanied by hypertrophy, which is provided with a uterus 5a and an egg. At least one of the tube portion 5b and the ovary portion 5c, and the oviduct portion 5b and the ovary portion 5c are respectively connected to at least one of the left and right sides so that a fluid can be sent to the inside of them to expand and enlarge. Or, it should consist of a combination of a model with normal morphology and one or more models with abnormal morphology (for example, enlarged) depending on the case. The above case is shown as an example in FIGS. 3 and 4, and FIG. 3-1 shows a form in which the pump 9 is connected to the right fallopian tube portion 5b ′ and is enlarged by air or the like. FIG. 4 shows a form in which the left ovary portion 5c ′ is connected to the pump 9 and enlarged. In this case, the degree of hypertrophy can be changed substantially arbitrarily by adjusting the amount of fluid discharged by the pump 9, including the normal case. 2 shows the above case, FIG. 2-2 is an example of mild hypertrophy (5a ″), and FIG. 2-3 is an example of severe hypertrophy (5a ″) (FIG. 2-1 is normal). In this case as well, education and practical training for a wide range of cases can be performed by combining models of abnormal morphology with various degrees of hypertrophy required among various cases. Further, the reproductive organ model 5 of the present invention can take not only hypertrophy but also other abnormal shapes, and therefore the present invention greatly contributes to education and practical training of gynecologic diagnosis.

The genital model 5 can be locked to the model base body at a predetermined position. This locking and releasing is performed by known means, but generally, the outer diameter of the replacement model 5 at a predetermined position is approximately equal to or slightly larger than the diameter of the communicating portion 6a of the vaginal portion 6 with the abdominal portion 7. deep. At that time, it is possible to facilitate the positioning by providing a groove on the outer periphery of the locking position of the genital model 5. Since the material of the subcutaneous member 3 and the genital model 5 are both soft, this locking and releasing can be easily performed. The replacement of the genital model 5 is performed from the abdominal cavity 7.

Further, the genital model 5 is provided with an intrauterine vaginal portion 5d, and the subcutaneous member 3 is provided with a rectal portion 8, respectively, for use in endoscopic vaginal probe and palpation, and rectal speculum and palpation. Even if they are there, education and practical training are possible. Further, in the present invention, since the genital model 5 can be locked in the front-rear direction, it is possible to imitate the condition of uterine retroflexion, which can also be taught and practiced.

The present invention is particularly useful as a gynecological diagnosis training model for colposcopy, sonde diagnosis, hysteroscope, laparoscopic diagnosis, and palpation education / practice, but also to select a genital model. Can be used for uterine diagnosis during pregnancy, puerperium, etc., and also for education and training such as endoscopic diagnosis of the rectum, palpation, and abdominal palpation. Therefore, it can make a great contribution in terms of medical education as a model for practicing gynecologic diagnosis.

[Effect of the device]

 Since the present invention has the above-mentioned configuration, it has the following remarkable effects as compared with the conventional training model. That is, (1) the genital model can take any form in which at least one of the uterine part, fallopian tube part, and ovarian part corresponds to normal or abnormal, so that it is accompanied by hypertrophy or is not accompanied by hypertrophy. A wide range of diagnostic techniques (endoscopes, palpation, etc.) can be effectively taught and practiced in virtually all cases including the above. (2) Normal and abnormal can be selected appropriately as the form of the genital model, so comprehensive education and training on gynecologic diagnosis including comparison of normal and abnormal findings can be conducted. (3) Since the epidermis member, the subcutaneous member, and the genital model are all made of a soft material that resembles a living body, it can be taught and practiced with the same feel as a living body, and the feeling at the time of diagnosis can be estimated beforehand. Can be raised. (4) Since the genital model is replaceable and can be locked easily in the front-back direction, it is possible to teach and practice uterine retroflexion.
