Description

  The present invention relates to a practical training tool that can be used for practical training and explanation in the nasal cavity, oral cavity, and pharynx, and more particularly, to a practical training tool that is suitable for performing practical training and explanation related to suction of sputum.

In nursing homes and hospitals, simple aspiration is performed for people who cannot or cannot easily produce secretions such as sputum. Simple suction is performed by inserting a catheter from the nostril or mouth to the pharynx.
If caregivers, nurses, doctors, etc. who are sucking in are not accustomed to inserting the catheter, it may take time to insert the tip of the catheter to the position of it, or it may fail, Problems such as injury to the oral cavity and pharynx at the tip of the catheter, burden on the person who is aspirated, and discomfort.
Therefore, it is desirable for a caregiver or the like to perform practical training such as insertion of a catheter and suction of a simple substance after insertion of the catheter.
As techniques for performing simple suction training, techniques described in Non-Patent Documents 1 and 2 below are conventionally known.

  In Non-Patent Document 1, in a human body lying down horizontally, a space from the nasal cavity or oral cavity to the esophagus and trachea is formed in the human body model from the head to the chest, and the nasal cavity, oral cavity, trachea A simulator for performing a suction exercise by putting a mock-up in is disclosed. In the configuration of Non-Patent Document 1, the left half including the pharynx from the nasal cavity of the human body is detachable, and the anatomical situation of the nasal cavity, oral cavity, and pharynx can be confirmed. It is configured to be able to confirm the state in which the nasogastric tube is inserted.

  In Non-Patent Document 2, in a human body lying down horizontally, a space from the nasal cavity or mouth to the trachea is formed inside the human body model from the head to the chest, and a simulated tongue is put in and sucked.

(Problems of conventional technology)
In the techniques described in Non-Patent Documents 1 and 2, a human body model (human body model) is formed up to the chest and is formed up to the trachea. Therefore, since the pharynx of the human body model is faithfully reproduced in the structure of the human body, a portion such as a concave portion that accommodates the simulated tongue is not formed in the pharynx.
In such a configuration, the simulated tongue easily flows and the position of the simulated tongue is difficult to stabilize. In particular, in a configuration in which the pharynx can be disassembled and attached as in Non-Patent Document 1, the simulated tongue tends to flow out of the attachment / detachment portion.

In addition, at the actual site of simple suction, in order to prevent adverse events such as vomiting associated with airway suction when performing simple suction, the top of the person is tilted about 30 degrees with respect to the top of the head. In many cases, suction is performed. That is, in many cases, suction is performed after tilting about 30 degrees by raising the upper body of a person or tilting the upper body of a nursing bed.
Therefore, it is desirable to perform training in a state inclined by 30 degrees during training. However, in the configurations described in Non-Patent Documents 1 and 2, the pharynx is reproduced too faithfully, so even if the simulated tongue is placed on the throat, the simulated tongue flows when the human body model is tilted. There is a problem that training to suck the tongue is very difficult. Therefore, although the simulators described in Non-Patent Documents 1 and 2 are commercially available, in actual training, there is a situation in which training is not performed using a simulated tongue.

  It is a technical object of the present invention to provide an instrument capable of simple suction training.

FIG. 1 is an overall explanatory view of a practical training tool for suction of Example 1;
FIG. 2 is an exploded explanatory view of a practical training tool for suction suction according to the first embodiment.
In FIG. 1 and FIG. 2, the practical suction training tool 1 of Example 1 has a pedestal 2. The pedestal portion 2 includes a pedestal plate 3 as an example of a main body of the pedestal portion. The base plate 3 is formed in a plate shape. An opening 3 a is formed at the center of the base plate 3. A pair of left and right leg portions 4 are formed at the left and right ends of the base plate 3. The leg portion 4 is formed in a plate shape extending downward. The pedestal plate 3 supports projections 6 and 7 as an example of a mounting portion on both the left and right sides of the opening 3a. The protrusions 6 and 7 are formed in a columnar shape extending upward from the base plate 3.

  1 and 2, a pedestal storage part 11 as an example of a simple storage part is detachably supported on the pedestal part 2. As for the container part 11, the flange part 12 as an example of a to-be-supported part is provided in the outer peripheral part. The flange portion 12 is formed larger than the opening 3 a and smaller than the interval between the protrusions 6 and 7. A plate portion 13 is formed inside the flange portion 12. A boundary portion between the plate portion 13 and the flange portion 12 is formed in a step shape, and the plate portion 13 is formed in a shape recessed downward with respect to the flange portion 12. The size of the plate portion 13 is formed corresponding to the size of the opening 3a. That is, the plate part 13 can be accommodated in a state of being fitted inside the opening 3a. A concave portion 16 having a shape recessed downward is formed in the right portion of the plate portion 13. The recess 16 is configured to be able to accommodate a simulated bag.

FIG. 3 is an exploded view of model parts.
1 to 3, a model part 21 as an example of a model part is supported above the tank housing part 11.
The model part 21 has a base plate 22 as an example of a base. Through holes 22a and 22b, which are examples of mounted parts, are formed at the left and right ends of the base plate 22, respectively. The through holes 22 a and 22 b are formed at positions corresponding to the protrusions 6 and 7. Further, an opening 22 c is formed on the right portion of the base plate 22. The opening 22 c is formed at a position corresponding to the recess 16 of the container part 11.

A head model 23 as an example of a main body of the model portion is supported on the upper surface of the base plate 22. The head model 23 is formed in a shape imitating an actual human head. The head model 23 of the first embodiment is configured from the head to the throat. In the head model 23, spaces 23a to 23e corresponding to the nostril 23a, the nasal cavity 23b, the mouth 23c, the oral cavity 23d, and the pharynx 23e are formed to imitate the human body. The lower end of the pharynx 23e is formed corresponding to the opening 22c. Therefore, the spaces 23 a to 23 e are configured to be connectable to the recess 16.
Further, the head model 23 of the first embodiment corresponds to a human head in a state where the top of the head is inclined by 30 degrees with respect to the horizontal.
Furthermore, the head model 23 of Example 1 is configured only by the left half of the head and throat. Therefore, it has the cross-sectional part 23f along the gravity direction in a human head.

A transparent plate 24 as an example of a transparent member is disposed facing the cross-sectional portion 23f. The transparent plate 24 is made of a transparent resin material. Therefore, in the model part 21 of Example 1, the spaces 23a to 23e of the head model 23 are configured to be visible from the outside through the transparent plate 24.
Further, a support plate portion 26 extending forward is supported at the lower end portion of the transparent plate 24. The lower end portion of the transparent plate 24 and the support plate portion 26 are detachably supported with respect to the base plate 22. An anti-slip rubber 25 as an example of an anti-slip member is supported on the lower surfaces of the transparent plate 24 and the support plate part 26. Therefore, the transparent plate 24 and the support plate portion 26 according to the first embodiment are held by the anti-slip rubber 25 in a state where the transparent plate 24 and the support plate portion 26 are placed on the upper surface of the base plate 22.

FIG. 4 is an explanatory view showing a state in which a blindfold member is mounted in the practical suction training tool of the first embodiment.
In addition, the transparent plate 24 of Example 1 can be arranged with a gap between the cross-sectional portion 23 f of the head model 23. In FIGS. 1 and 4, a blindfold sheet 27 is inserted between the cross-sectional portion 23 f and the transparent plate 24 as an example of a blindfold member. The blindfold sheet 27 is made of an opaque material, and as an example, can be made of white vinyl chloride. Further, the blindfold sheet 27 of Example 1 is formed along the outer shape of the transparent plate 24. Therefore, in a state where the blindfold sheet 27 is inserted between the cross-sectional portion 23f and the transparent plate 24, the spaces 23a to 23e inside the head model 23 are hidden and cannot be visually recognized from the outside.

Further, the blindfold sheet 27 of the first embodiment is formed with a tab 27a as an example of an operation unit. The tab 27a is provided for performing operation by picking it with a finger when the blindfold sheet 27 is attached or detached.
Furthermore, as shown in FIG. 3, the image 27b corresponding to the spaces 23a to 23e is printed on the surface facing the cross-sectional portion 23f of the blindfold sheet 27 of the first embodiment.

(Operation of Example 1)
FIG. 5 is a diagram for explaining the operation of the practical training tool for suction of Example 1 and is a cross-sectional view taken along the line V-V in FIG.
In FIG. 1 and FIG. 5, in the practical skill training tool 1 for the suction of the first embodiment having the above-described configuration, the simulated tongue 31 is accommodated in the concave portion 16 of the tongue accommodating part 11 and is attached to the pedestal portion 2. The model part 21 can be mounted from above. Accordingly, in this state, a person who performs training can perform training for inserting the suction catheter 32 from the nostril 23a or the mouth 23c to the recess 16. Then, after the suction catheter 32 is inserted, the simulated tongue 31 can be sucked by operating a suction device (not shown) connected to the other end of the suction catheter 32, and training of simple suction skills is performed. Is possible.

  Therefore, in the practical skill training tool 1 for suction of the first embodiment, the simulated tongue 31 is accommodated in the recess 16 and the simulated tongue 31 is prevented from flowing. Therefore, with the simple suction practical training tool 1 according to the first embodiment, it is possible to perform practical practical training for simple suction that is difficult with the conventional configuration in which the position of the simulated tongue is unstable.

In addition, since the conventional simulator is a model along the horizontal direction, if it is tilted 30 degrees where the actual suction is performed, the simulated tongue flows without staying at a predetermined position, and training is performed. It was difficult. Even when training only the insertion of a catheter that does not use a mock-up, when using a model along the horizontal plane, another person who is not the person performing the training supports it while tilting the simulator, or between the installation surface and the simulator. It was tilted by about 30 degrees, for example by sandwiching an object between them. Therefore, there is a risk that the training cannot be performed alone, or that the simulator becomes unstable when tilted with an object sandwiched, and the simulator may fall during training.
On the other hand, in the practical training tool 1 for the simple suction according to the first embodiment, the head model 23 is configured to be inclined 30 degrees from the horizontal. Therefore, training in a state inclined by 30 degrees can be easily performed. In particular, in the practical training tool 1 for tan suction of the first embodiment, the simulated tongue 31 is accommodated in the concave portion 16, and the simulated tongue 31 is prevented from flowing even in the head model 23 inclined by 30 degrees. Yes.

  Further, in the practical suction training tool 1 according to the first embodiment, the plate portion 13 is arranged in a step shape with respect to the flange portion 12, and the concave portion 16 is formed in the plate portion 13. Therefore, even if a large amount of simulated tongue is put into the recess 16 or the catheter is inserted into the recess 16 during practical training, the simulated tongue overflows from the recess 16 and is received on the upper surface of the plate portion 13. If the plate portion 13 is not stepped, if the simulated tongue overflows, the bottom surface of the model part 21 is soiled or wetted, or the simulated tongue flows back into the head model 23, There is a possibility that the inside of the model 23 may be soiled, and there is a possibility that the cleaning work becomes troublesome. On the other hand, in Example 1, it can be expected that the dirt or the like of the model part 21 is reduced even if the simulated tongue overflows from the recess 16.

  Furthermore, in the practical training tool 1 for suction of the first embodiment, since the transparent plate 24 and the like are placed in the model part 21, it can be easily removed. Therefore, the spaces 23a to 23e inside the head model 23 can be easily opened to the outside. In some cases, the internal spaces 23a to 23e may be reproduced with a condition close to the body by applying a lubricant before starting training. In addition, in order to perform training or explanation for sucking a swallowed object (for example, yogurt or the like) in addition to the person, it is also conceivable to use an object other than the person in the spaces 23a to 23e. Therefore, in the first embodiment, even when a lubricant is applied to the spaces 23a to 23e or something is placed on the spaces 23a to 23e, the internal spaces 23a to 23e can be easily opened to the outside. Therefore, these operations are easily performed. It is possible. In addition, it is possible to easily perform a cleaning operation such as wiping off the lubricant after the training is completed.

Furthermore, in the practical training tool 1 for simple suction according to the first embodiment, the spaces 23 a to 23 e inside the head model 23 are visible through the transparent plate 24 when the blindfold sheet 27 is not attached. Therefore, the position of the suction catheter 32, the inserted state, the state in which the simulated tongue 32 is sucked, and the like can be visually confirmed. Therefore, when a large number of people confirm at a seminar or a seminar, or when the position of the suction catheter 32 is a beginner and it is necessary to confirm the position at the time of insertion, the suction catheter 32 is visually checked. Insertion is possible.
Moreover, in the practical training tool 1 for the simple suction according to the first embodiment, the spaces 23 a to 23 e inside the head model 23 are not visible when the blindfold sheet 27 is attached. If visual recognition is possible at the time of training, there is a place to rely on eyes, and it is easy to look at it, but when performing simple suction to an actual person, the spaces 23a to 23e are not visible, It is necessary to insert the suction catheter 32 depending on the sense of the hand. Therefore, in the practical suction training tool 1 according to the first embodiment, by wearing the blindfold sheet 27, it is also possible to perform a training for insertion by relying on the sense of the hand without visually recognizing the spaces 23a to 23e. .

  Furthermore, in the practical training tool 1 for the suction of the first embodiment, it can be used not only for the suction catheter 32 for sucking the tongue but also for the practical training for inserting an endoscope into the nasal cavity, oral cavity, pharynx, and the like. is there. At this time, when the blindfold sheet 27 is attached and the image 27b is not formed on the blindfold sheet 27, when the blindfold sheet 27 side is viewed with the endoscope, the image taken with the endoscope becomes white. There is a risk of being confused or inadequate as practical training. On the other hand, in Example 1, the image 27b is formed on the blindfold sheet 27, and even when the endoscope is used, the trainee can perform practical training with less discomfort.

  Furthermore, in the practical training tool 1 for the simple suction according to the first embodiment, the head model 23 is the left half of the human body. In the case of the head model of the right half of the human face, when a right-handed person performs training to insert the suction catheter 32 with the right hand, the right hand moves in an empty space. However, when performing simple suction in an actual person, the right half of the person's face exists in a space where there is nothing during training, so what can be done during training cannot be performed in the actual person There is a fear. On the other hand, in the practical training tool 1 for simple suction according to the first embodiment, since the left half of the human face exists, when training with the right hand, the human face is touched when the suction catheter 32 is inserted. Whether or not can be inserted while checking at the time of training. Therefore, with the simple suction practical training tool 1 of the first embodiment, it is possible to train the insertion operation of the suction catheter 32 in a situation close to that of an actual person.

Moreover, in the practical training tool 1 for the suction of the first embodiment, the tank storage part 11 is configured to be detachable with respect to the model part 21 and the pedestal portion 21, and the tank storage part 11 is compared with a configuration in which it is not removable. It is possible to easily perform the operation of putting the simulated sample 31 in the concave portion 16 and the operation of cleaning and disinfecting the parts 11 and 21 after the training is completed.
Further, in the conventional simulator, the chest, trachea, and esophagus are faithfully reproduced on the human body, and since it has been reproduced faithfully, it has been difficult to train suction. On the other hand, in Example 1, it is specialized for practical training of sputum suction in the pharynx, so it is unnecessary for practical training of sputum suction, so to speak, such as the chest and trachea parts formed by conventional simulators These parts are omitted, and unnecessary members and unnecessary structures are deleted. Therefore, it is possible to reduce the cost of the simple suction practical skill training tool 1.
