Description

[Technical field]

[0001] The present invention relates to a medical training mannequin used for conducting medical training in endoscopic examination. [Background technology]

[0002] Endoscopy, which involves inserting an endoscope into internal organs such as the nasal cavity and larynx to perform direct observation, is an extremely useful examination method that allows for early and appropriate treatment of patients' main complaints and past illnesses, and is therefore widely performed in various medical settings. On the other hand, when performing such endoscopic examinations, not only do precise techniques and knowledge are required to ensure the safety of patients, but it is also important to analyze and understand the images obtained during endoscopic examinations, and to learn in advance the necessary medical procedures to be performed.

[0003] In order to help medical professionals acquire the skills and knowledge related to such endoscopic examinations, a medical training mannequin that simulates the shape of the human body is necessary, and various proposals regarding such medical training mannequins used for training in endoscopic examinations have been made in the following patent documents, etc. These medical training mannequins have organ-modeled sections corresponding to the internal organs of a human body, and the anatomical shapes of the organ walls through which an endoscope is inserted and observed are reproduced in the organ-modeled sections. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2004-347623 A [Patent Document 2] JP 2019-090866 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] However, since the above-mentioned conventional medical training dummies are designed for the purpose of helping beginners who have just started using endoscopes learn how to operate an endoscope, the organ-modeled parts that mimic internal organs merely reproduce the anatomical form in a normal state or one anatomical form selected from among various pathological states including diseases or abnormalities. Therefore, the images obtained through the endoscope only show either a form in a healthy state or one of various pathological forms.

[0006] As described above, conventional medical training dummies are unable to reproduce a wide range of simulated pathological conditions, such as various diseases or abnormalities that occur in the organs of the human body. As a result, there is a problem in that it is not possible to train in practical patient care, such as considering additional tests to be performed, future treatments, dietary guidelines, etc., for various pathological conditions, such as the patient's predetermined chief complaint or past illnesses.

[0007] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a medical training mannequin that allows for easy and satisfactory training in practical patient care in response to a wide variety of pathological conditions, including various diseases or abnormalities. [Means for solving the problem]

[0008] In order to achieve the above object, the invention of claim 1 provides a medical training human body model having an organ modeling part that simulates the shape of the human body and that can be attached and detached to a mannequin body, the organ modeling part being configured as a plurality of types of interchangeable replacement parts, each of which has a different anatomical shape that reproduces a pathological condition, including a plurality of types of diseases or abnormalities, that occurs in the wall surface of the internal organ, and one or more selected from the plurality of types of replacement parts are attached to the mannequin body.

[0009] According to the invention of claim 1 having such a configuration, by attaching any one of the multiple types of replacement parts constituting the multiple types of organ modeling parts to the mannequin body and inserting the endoscope, an examination for a pathological condition including a disease or abnormality reproduced by the replacement part attached to the mannequin body at that time is simulated, and by replacing it with another replacement part and inserting the endoscope, an examination for a different pathological condition is simulated. Therefore, it is possible to realize extremely practical training in patient care, such as considering additional examinations to be performed and future treatments and dietary guidelines for a wide range of pathological conditions including various diseases or abnormalities.

[0010] In this case, as in the invention of claim 2, it is desirable that the mannequin body has a form that simulates the neck to head of a human body, and that the replacement parts that constitute the organ modeling section have an anatomical form that simulates the form of the walls of the nasal cavity, pharynx, or larynx, and that the anatomical form of the replacement parts forms a space that is larger than the actual space of the internal organ into which the endoscope is inserted.

[0011] According to the invention of claim 2 having such a configuration, when inserting the endoscope into the replacement part, the risk of part of the endoscope coming into contact with the wall surface of the replacement part is reduced, and damage to the delicate endoscope which is vulnerable to impacts is prevented, so that the endoscope can be inserted smoothly, safely and with ease.

[0012] Furthermore, as in the invention of claim 3, it is desirable that the replacement part that reproduces the shape of the wall surface of the pharynx or larynx be configured to be attached from below to above the neck of the mannequin body, and that the replacement part that reproduces the shape of the wall surface of the nasal cavity be configured to be attached from behind to the head of the mannequin body.

[0013] According to the invention of claim 3 having such a configuration, external light is less likely to enter the inside of the replacement part, and particularly when the replacement part is attached from the lower part of the neck toward the upper part, the influence of external light is significantly reduced, making it possible to clarify the image obtained through the endoscope.

[0014] Furthermore, as in the invention of claim 4, it is desirable that the replacement part has a positioning locking portion that engages at a predetermined position when attached to the mannequin body.

[0015] According to the invention as defined in claim 4 having such a configuration, the replacement parts can be easily and accurately attached to the mannequin body.

[0016] As in the invention according to claim 5, it is preferable that the positioning locking portion includes an external light blocking member that protrudes in a state to block light directed from the outside to the inside of the replacement part.

[0017] According to the invention as defined in claim 5 having such a configuration, deterioration of image quality caused by the influence of ambient light is prevented.

[0018] Furthermore, as in the invention of claim 6, it is desirable that the mannequin body be equipped with an electronic device mounting section to which electronic devices including a monitor that displays the output image from the endoscope are fixed, and a mannequin support section that fixes the mannequin body itself to an external fixed member.

[0019] According to the invention of claim 6 having such a configuration, while operating the endoscope, the operating status can be confirmed within the same field of view on a nearby monitor, improving the operability of the endoscope, and by arranging the medical training mannequin in a state close to the actual site, practical training becomes possible. Effect of the Invention

[0020] As described above, in the medical training dummies of the present invention, the organ modeling sections that reproduce the morphology of internal organs into which an endoscope is inserted are configured as multiple types of interchangeable replacement parts, and an appropriate one from the multiple types of replacement parts that form different anatomical forms that reproduce multiple types of diseases or abnormalities is selected and attached to the mannequin body, and a simulated endoscopic examination is performed for the disease or abnormality that the replacement part reproduces.In addition, by replacing the replacement part with another replacement part and performing a simulated endoscopic examination, it is possible to realize extremely practical training in patient care, including the necessary medical measures to be taken, such as considering additional tests that should be performed for multiple types of diseases or abnormalities and the course of treatment that should be administered in the future.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an embodiment of the medical training mannequin according to the present invention will be described in detail with reference to the drawings. In the following description, the directions of "front", "back", "upper" and "lower" refer to the directions of a human being standing normally.

[0023] [About the use of medical training mannequins] First, as shown in Fig. 1, the medical training mannequin 10 according to the present invention is used in a state fixed to a fixed member 20 such as a dental unit or a wheelchair, assuming practice in, for example, a medical facility. As also shown in Fig. 2, the medical training mannequin 10 in this embodiment is in a state of use held in a position slightly spaced forward (to the left in Fig. 2) from the backrest plate 21 of the dental unit 20, which is the fixed member.

[0024] In the dental unit 20 as the fixed member described above, a ring-shaped support bracket 23 is attached directly below the headrest portion 22 located above the backrest plate 21, and one end portion of the round bar-shaped clamp member 11 is fixed to the support bracket 23, so that the clamp member 11 is positioned in a cantilevered manner extending forward (to the left in Figure 2) from the backrest plate 21 of the dental unit 20.

[0025] Meanwhile, a mounting hole 12 is provided in the upper part of the back of the head of the medical training mannequin 10 so as to be recessed and fitted along the outside of the clamp member 11, and the mounting hole 12 of the medical training mannequin 10 is fitted from the front (left side in FIG. 2) to the rear (right side in FIG. 2) into the clamp member 11 fixed to the dental unit 20. At this time, the free end portion (left end portion in FIG. 2) of the clamp member is bifurcated into two branches and elastically bends in the radial direction, and the radial elastic repulsive force of the clamp member 11 holds the medical training mannequin 10 in a cantilevered state.

[0026] In addition, when the medical training mannequin 10 in this held state is again moved so as to be pushed forward (to the left in Figure 2), the mounting hole 12 of the medical training mannequin 10 slides forward (to the left in Figure 2) along the clamp member 11 extending forward (to the left in Figure 2) from the backrest plate 21 of the dental unit 20, thereby allowing the medical training mannequin 10 to be removed.

[0027] Then, as described above, the tip portion 31a of the flexible fiberscope 31 provided on the endoscope 30 is inserted into the inside of the medical training mannequin 10 from the front (left side in FIG. 2) of the dental unit (fixed member) 20 supported in a cantilevered manner. Then, an examination image obtained through the inserted endoscope 30, that is, an image of a swallowing endoscopy examination showing the morphology of the internal organs reproduced inside the medical training mannequin 10, is displayed on the screen of a monitor 40 fixed to an electronic device attachment portion 13 consisting of a clamp rod or the like extending in a cantilevered manner from the side of the head of the medical training mannequin 10.

[0028] [About the composition of the medical training mannequin] The detailed structure of the medical training mannequin 10 used in this manner will be described below.

[0029] The medical training human model 10 according to this embodiment shown in Figures 1 to 5 comprises a mannequin body 14 in which the external shape of the human body from the head and face to the neck is roughly reproduced, and a nose replacement part 15 and a throat replacement part 16 as organ modeling parts which simulate internal organs are removably attached to the mannequin body 14.

[0030] [Mannequin body configuration] The mannequin body 14 is shaped by molding or hand-making resin, silicone, etc., and of the external shape of the head and face through to the neck which is simulated by the mannequin body 14, a portion of the back of the head which is not necessary for the operation and handling of the endoscope 30 is not reproduced and is instead cut out into a bow-shaped recess.

[0031] A hollow storage space is formed in such a mannequin body 14, into which the above-mentioned nose replacement part (organ modeling part) 15 and throat replacement part (organ modeling part) 16 can be attached. More specifically, a nose attachment space 14a consisting of a hollow passage extending in the front-rear direction of the human body is formed in the approximate center of the mannequin body 14, and a throat attachment space 14b consisting of a hollow space extending in the up-down direction of the human body is formed in the lower end part of the mannequin body 14.

[0032] A nose replacement part (organ modeling part) 15 as shown in Figures 6 and 7 is inserted inward from the rear of the human body into the upper nose mounting space 14a, and is attached to the inside of the lower throat mounting space 14b. A throat replacement part (organ modeling part) 16 as shown in Figures 8 and 9 is inserted inward from below the neck into the inside of the lower throat mounting space 14b. The structures of the nose replacement part 15 and the throat replacement part 16 will be described in detail later.

[0033] Here, in the approximate center of the face of the mannequin body 14 described above, i.e., in the area corresponding to the "nose" of the human body, a vertically elongated central opening 14c corresponding to the external shape of the "nose" is formed in an approximately elliptical shape. Then, from the central opening 14c corresponding to the external shape of the "nose" toward the rear (to the right in FIG. 5), the nose mounting space 14a described above extends while expanding in cross-sectional area, and further extends toward the rear to the rear end (the right end in FIG. 5) while maintaining a constant cross-sectional area.

[0034] The rear end (right end in FIG. 5) of the nose mounting space 14a is formed into a substantially rectangular opening, and the nose replacement part (organ modeling part) 15 described above is inserted forward (to the left in FIG. 5) from the rear end opening of the nose mounting space 14a toward the inner space, thereby achieving the mounted state.

[0035] In this way, the nose replacement part (organ modeling part) 15 is structured to be detachable from the nose mounting space 14a described above, and the nose replacement part 15, which is inserted forward (left side in Fig. 5) and attached, can be removed by pulling it out toward the opposite rear (right side in Fig. 5). At the rear end portion (right end portion in Fig. 7) of this nose replacement part 15, a gripping part 15a made of a plate-like member with a crescent-shaped side is provided in a state of protruding toward the rear, and the nose replacement part 15 can be easily attached and removed by grasping the gripping part 15a with the hand.

[0036] As described above, when the nose replacement part (organ modeling part) 15 is completely mounted inside the nose mounting space 14a, the nose modeling part 15b formed at the front end part (left end part in FIG. 5) of the nose replacement part 15 is made to protrude slightly forward from the central opening 14c provided on the face part of the mannequin main body 14. The front end surface of the nose modeling part 15b is provided with nostril corresponding holes 15c corresponding to the "nostrils" of the human body. The detailed structure of the nose replacement part 15 including the nostril corresponding holes 15c will be described later.

[0037] Furthermore, a flexible cover 14d made of a transparent flexible material such as silicone and shaped to resemble the outer surface of the nose is attached to the central opening 14c provided in the mannequin body 14 as described above. This flexible cover 14d has an opening for inserting the endoscope 30 at a position corresponding to the nostril-corresponding hole 15c described above.

[0038] By providing such a transparent flexible cover 14d, the position and operating state of the endoscope 30 inserted into the nose replacement part (organ modeling part) 15 can be roughly visually observed, as described below, and even if the endoscope 30 moves significantly, impacts due to contact, etc. are absorbed by the flexible cover 14d, preventing breakage or damage to each part.

[0039] The portion of the mannequin body 14 that corresponds to the neck extends downward from the neck to a position that corresponds to the shoulder of a human body, and its lower end portion forms a substantially circular bottom surface. In the portion of the mannequin body 14 that corresponds to the neck, a throat mounting space 14b for mounting the above-mentioned throat replacement part (organ modeling part) 16 is formed so as to form a hollow passage extending in the vertical direction. The structure of the throat replacement part 16 will also be described in detail later.

[0040] The lower end of the throat mounting space 14b (lower end in FIG. 5) is an opening shaped to correspond to the "throat" of a human body at the bottom surface of the neck of the mannequin main body 14. The throat replacement part (organ modeling part) 16 is inserted upward from the lower end opening of the throat mounting space 14b toward the inner space to be attached. The throat replacement part 16 is structured to be detachable from the throat mounting space 14b, and the throat replacement part 16 inserted upward to be attached can be removed by pulling it out downward in the opposite direction.

[0041] At this time, a hollow passage corresponding to the "oropharynx" of the human body is formed in the portion between the throat attachment space 14b and the nose attachment space 14a in the mannequin body 14 described above, and a shape that simulates the anatomical forms of the "oropharynx," "hypopharynx," and "tongue" of the human body is formed on the inner wall surface of the hollow passage.

[0042] [Replacement parts configuration] 6 and 7, the front end surface of the nose modeling portion 15b of the nose replacement part (organ modeling portion) 15 has two nostril corresponding holes 15c, 15c, which are arranged in parallel close to each other on the left and right, and in the area from the two nostril corresponding holes 15c, 15c to the rear, a nasal cavity corresponding space 15d, which corresponds to the nasal cavity of the human body, is formed to form a bulging space. In the approximate center of the nasal cavity corresponding space 15d, a thin plate-like nasal septum corresponding plate 15e, which corresponds to the nasal septum of the human body, is arranged to extend in the front-rear direction, and the nasal septum corresponding plate 15e divides the above-mentioned nasal cavity corresponding space 15d into two spaces, left and right.

[0043] The anatomical shape of the path through which the endoscope 30 is inserted from the "nasal cavity" to the "nasopharynx" of the human body is simulated on the inner wall surface 15f of the nasal cavity-corresponding space 15d provided in such a nose replacement part (organ modeling part) 15. In particular, in this embodiment, realistic simulated pathological conditions that are in line with reality, including the color tones of the "mucous membrane" and the like, are reproduced so that realistic images (see Figs. 14 to 16) can be experienced through the monitor 40.

[0044] Such nose replacement parts (organ modeling parts) 15 are prepared in advance in a number of different shapes that are mutually interchangeable, and one of the nose replacement parts 15 appropriately selected is attached by being inserted forward from the rear into the nose mounting space 14a of the mannequin body 14. Once attached to the mannequin body 14, the nose replacement part 15 is removed by being pulled backward from the nose mounting space 14a and reused.

[0045] More specifically, each of the above-mentioned multiple types of nose replacement parts (organ modeling parts) 15 has a different anatomical form that reproduces each of multiple types of diseases or abnormalities occurring on the inner wall surface 15f of the nasal cavity corresponding space 15d from the "nasal cavity" to the "nasopharynx" of the human body. As the anatomical form, for example, a form that reproduces "nasal polyps 15g" as shown in Fig. 10(a), a form that reproduces "edema of the nasal mucosa 15h" as shown in Fig. 10(b), or a form that reproduces "intrusion of saliva due to nasopharyngeal closure insufficiency 15i" as shown in Fig. 10(c) can be adopted, but anatomical forms that reproduce various other simulated pathological conditions can also be adopted.

[0046] The inner wall surface 15f having an anatomical form in these nose replacement parts (organ modeling parts) 15 is configured to form a space slightly enlarged compared to the actual space from the "nasal cavity" to the "nasopharynx" of the human body. This is a measure against the possibility that, for example, when an unskilled surgeon inserts the fiberscope 31 of the endoscope 30 into the same region, the tip portion 31a of the fiberscope 31 may come into strong contact with the inner wall surface 15f of the nose replacement part 15. By adopting the configuration of the enlarged space as described above, it is possible to prevent damage to the delicate fiberscope 31, which is vulnerable to impact. As a result, the insertion operation of the endoscope 30 can be performed smoothly and safely with plenty of room.

[0047] Furthermore, a positioning locking portion 15j is provided protruding downward from the lower edge of the rear end portion of the nose replacement part (organ modeling portion) 15 as a stopper member that engages at a predetermined position when the nose replacement part 15 is attached to the mannequin body 14. By providing such a positioning locking portion 15j, the nose replacement part 15 can be easily and accurately attached to the mannequin body 14. At this time, if an attraction holding means such as a magnet is provided at the positioning locking portion 15j and the portion facing it, the ease of attachment of the nose replacement part 15 can be further improved.

[0048] Furthermore, a uvula-corresponding piece 15k, which reproduces the anatomical form of the uvula of the human body, is provided at a position corresponding to the "uvula" of the human body on the bottom surface of the nose replacement part (organ modeling part) 15, in a state of hanging down while curving downward. A disturbance light shielding piece 15m made of a lid-like member is provided in a state of protruding downward from the bottom surface of the nose replacement part 15 so as to face the uvula-corresponding piece 15k from behind (the left side of FIG. 5).

[0049] As shown in FIG. 5, when the nose replacement part 15 is attached to the nose attachment space 14a, the disturbance light shielding piece 15m is configured to cover from behind the gap that is generated between the lower edge of the rear end of the nose replacement part 15 and the passage that forms the nose attachment space 14a. By blocking light traveling from the outside to the inside of the nose replacement part 15, the disturbance light is prevented from entering, and the disturbance light shielding piece 15m has the function of preventing a deterioration in the image quality obtained through the endoscope 30.

[0050] On the other hand, as shown particularly in Figures 8 and 9, the inner wall surface 16a of the above-mentioned throat replacement part (organ modeling part) 16 simulates the anatomical shape of the path along which the endoscope 30 is inserted from the "hypopharynx" to the "larynx" of the human body, and in particular, realistic simulated pathological conditions that are in line with reality, including the color tones of the "mucous membrane" etc., are reproduced so that realistic images (see Figures 14 to 16) can be experienced through the monitor 40.

[0051] A plurality of different types of throat replacement parts (organ modeling parts) 16 that are mutually interchangeable are prepared in advance, and one of the plurality of types of throat replacement parts 16 is appropriately selected and attached by being inserted from below to above into the throat attachment space 14b of the mannequin body 14. Once the throat replacement part 16 is attached to the mannequin body 14, it is removed by being pulled downward from the throat attachment space 14b and reused.

[0052] In this case, if an attraction and holding means such as a magnet is provided on a part of the above-mentioned throat replacement part (organ modeling part) 16 and its opposing portion, the ease of mounting the throat replacement part 16 can be further improved.

[0053] Here, each of the above-mentioned multiple types of throat replacement parts (organ modeling parts) 16 has a different anatomical form that reproduces each of multiple types of diseases or abnormalities occurring on the inner wall surface 16a from the "hypopharynx" to the "larynx" of the human body. The anatomical form may be, for example, a form that reproduces "pharyngeal and laryngeal residue 16b of food" in a swallowing patient as shown in Figures 11(a) and (b), a form that reproduces "larynx penetration 16c of food" as shown in Figures 12(a) and (b), or a form that reproduces "aspiration of saliva 16d" as shown in Figures 13(a) and (b), but anatomical forms that reproduce various other simulated pathological conditions may also be adopted.

[0054] According to the medical training mannequin 10 of this embodiment having the above-mentioned configuration, by mounting any one of the multiple types of nose replacement parts (organ modeling parts) 15 and throat replacement parts (organ modeling parts) 16 constituting the multiple types of organ modeling parts on the mannequin body 14 and inserting the endoscope 30, an examination of a pathological condition including a disease or abnormality reproduced by each of the replacement parts 15, 16 mounted on the mannequin body 14 at that time is simulated. As a result, images of the anatomical forms of the "nasal cavity", "nasopharynx", and "larynx", for example, as shown in Fig. 14, are obtained in the same way as in the case of a human body.

[0055] Furthermore, with the medical training mannequin 10 according to this embodiment, if replacement parts 15, 16 having different shapes are selected from a plurality of types of nose replacement parts (organ modeling parts) 15 and throat replacement parts (organ modeling parts) 16 and replaced with the original replacement parts 15, 16 by mounting the replacement parts 15, 16, and then inserting the endoscope 30, a test for a different pathological condition can be simulated. For example, images of anatomical forms related to "abnormality of the nasal cavity" and "intrusion of saliva into the nasopharynx" as shown in Fig. 15 and images of anatomical forms related to "various pharyngeal symptoms" as shown in Fig. 16 can be obtained in the same way as in the case of a human body.

[0056] Thus, with the medical training mannequin 10 of this embodiment, by using an appropriately selected replacement part from among a plurality of types of nose replacement parts (organ modeling parts) 15 and throat replacement parts (organ modeling parts) 16, extremely practical training in patient care can be realized, such as considering additional tests to be performed, future treatments, and dietary guidelines for a wide range of pathological conditions including a plurality of types of diseases or abnormalities.

[0057] In this embodiment, the throat replacement part (organ modeling part) 16 is attached to the neck of the mannequin body 14 from below toward above, which makes it difficult for ambient light to enter the throat replacement part 16. In addition, in this embodiment, the rear end of the nose replacement part (organ modeling part) 15 is provided with an ambient light shielding piece 15m, which further reduces the influence of ambient light. This configuration makes it possible to clarify the image obtained through the endoscope 30.

[0058] Furthermore, according to the invention of this embodiment, while operating the endoscope 30, the operating status of the endoscope 30 can be confirmed within the same field of view on the nearby monitor 40, thereby improving the operability of the endoscope 30, and by arranging the medical training mannequin in a state approximating the actual site, even more practical training is possible.

[0059] The invention made by the present inventor has been specifically described above based on one embodiment, but it goes without saying that this embodiment is not limited to the above-described embodiments and can be modified in various ways without departing from the gist of the invention.

[0060] For example, in the above-described embodiment, a configuration is adopted in which one selected from multiple types of replacement parts is attached to the mannequin body, but it is also possible to select multiple replacement parts and attach them to the mannequin body.

[0061] Furthermore, the above-described embodiment is directed to simulating the nasal cavity and larynx in the head and throat of the human body to conduct training in endoscopic examination of swallowing, but it goes without saying that the embodiment can be similarly applied to training in endoscopic examination of various organ-shaped parts that are reproductions of other parts of the human body.
