Description

Technique training kit and technique training method

[0001] The present invention relates to a technique training kit and a technique training method.

[0002] Many procedures performed by healthcare professionals during medical procedures involve invisible invasive procedures, such as needle insertion, scalpel incision, and tracheal intubation. Mastering these procedures is crucial to reducing medical accidents and complications caused by blind procedures. For example, epidural anesthesia is a highly effective anesthesia method that provides significant analgesia. However, it is a challenging procedure requiring experience because it involves puncturing the narrow interlaminar space. Because punctures are generally performed blindly, it is difficult for the practitioner to accurately determine the position of the needle tip relative to the bone and spinal cord. Although punctures can sometimes be performed under ultrasound guidance, it is often difficult to clearly visualize the needle tip and the interlaminar space. Therefore, mastering blind puncture techniques is the most practical way to increase the success rate of epidural anesthesia and reduce complications.

[0003] Conventionally, beginners and inexperienced persons have learned the procedure by repeatedly practicing using a commercially available simulator that mimics part or all of a living body, from the surface to the inside of the body, while learning the procedure's procedures, techniques, etc. As simulators, for example, various types of puncture simulators, puncture models, incision models, etc. are commercially available (see, for example, Non-Patent Document 1).

[0004] Kyoto Scientific Co., Ltd., product information "Simulator", [online], [searched March 8, 2024], Internet <URL: https: / / www.kyotokagaku.com / jp / products / search_cate / >

[0005] However, many of the commercially available simulators described in Non-Patent Document 1 and the like have opaque sections where puncture, incision, intubation, etc. are performed, which poses a problem that when training in procedures such as puncture, incision, and intubation, it is not possible to confirm the actual movements of the needle, scalpel, etc. As a result, for example, when a procedure fails, it is often difficult to understand the cause of the failure. Furthermore, some commercially available simulators have transparent sections where puncture, incision, intubation, etc. are performed so that the internal structure of the human body can be visually observed, but when training in the procedures, opaque pads or the like are attached to the surface to simulate the blind situation in actual clinical practice, which still poses a problem that it is not possible to confirm the movements of the needle, scalpel, etc.

[0006] In clinical practice, for example, when administering epidural anesthesia, the needle tip is moved along the spine to locate the intervertebral space while referring to the morphology of the spine, such as the vertebral arch, spinous processes, and facet joints. For this reason, it is considered important for trainees to understand the feel (e.g., the feel of needle manipulation on the spine) and the actual movement (e.g., the appearance of needle manipulation) in order to improve their technique.

[0007] The present invention has been made in light of these problems, and aims to provide a procedural training kit and procedural training method that enable training of procedural skills in a blind state while visualizing the movements.

[0008] In order to achieve the above-mentioned object, a first procedural training kit according to the present invention is a procedural training kit for training in procedural techniques that involve invasiveness to a living organism, and comprises a biological model that imitates part or all of a living organism from the surface to the inside of the body and is arranged so that the internal structure of the body can be seen, a transparent or translucent covering material that covers at least the surface side of the biological model and is colored a first color, and a transparent or translucent filter that is colored a second color, wherein the biological model and the covering material are made of a material that can be invasively used in the procedure, and the first color and the second color are colors that make it difficult to see the inside of the body of the biological model when the biological model covered with the covering material is viewed through the filter.

[0009] A second procedural training kit according to the present invention is a procedural training kit for training in procedural procedures that involve invasive procedures on a living organism, and is configured to simulate part or all of a living organism from the surface of the organism to the inside of the organism, and is configured so that the internal structure of the organism can be seen, and is characterized in that it has a biological model in which at least the surface or superficial layer on the surface side of the body is colored a first color, and a transparent or translucent filter colored a second color, the biological model being made of a material that can be invasively used in the procedure, and the first color and the second color being colors that make it difficult to see the inside of the body of the biological model when the biological model is viewed through the filter.

[0010] A third procedural training kit according to the present invention is a procedural training kit for training in procedural invasiveness using a biological model that mimics part or all of a biological body from the surface to the inside of the body, the kit comprising: a transparent or translucent covering material colored a first color that is arranged to cover at least the surface side of the biological model; and a transparent or translucent filter colored a second color, the covering material being made of a material that can be invasively used in the procedural invasiveness, the first color and the second color being colors that make it difficult to see the inside of the biological model when the biological model covered with the covering material is viewed through the filter. In the procedural training kit according to the third invention, it is preferable that the biological model used is arranged so that internal structures can be seen.

[0011] The procedure training kits according to the first to third aspects of the present invention can be used to train in procedures such as needle manipulation, puncture, incision, insertion and placement of catheters, endoscopes, implants, treatment instruments, and medical devices, or intubation. That is, the procedure training kits according to the first to third aspects of the present invention allow trainees to train in invasive procedures while viewing, through a filter, a biological model covered with a covering material or a biological model whose surface or superficial layer is colored, thereby enabling training in procedures blindly, without being able to see the inside of the biological model, as in actual clinical practice.

[0012] Furthermore, in the procedural training kits according to the first to third aspects of the present invention, when the biological model is viewed without a filter, the covering material and the colored surface or superficial layer of the biological model are transparent or translucent, allowing the inside of the biological model to be seen. Furthermore, the inside of the biological model can be seen from parts of the biological model not covered by the covering material, such as the side of the biological model, or from parts other than the colored surface or superficial layer of the biological model. Therefore, when a trainee is practicing a procedural technique, the trainee can visualize the movement of the needle or scalpel during training by capturing a video of the visible inside of the biological model using, for example, a video camera. This allows the trainee to receive feedback on the video of the training, allowing the trainee to compare the feel of the needle or scalpel during training with the movement of the actual needle or scalpel, the blade or tube during intubation, and to identify the cause of any failures, which is effective in mastering and improving the procedural technique.

[0013] In addition, observers observing the trainee's training without using a filter can also see the movements of the trainee's needle, scalpel, blade and tube during intubation, etc. This allows, for example, the trainee to receive advice on the movements of the needle, scalpel, blade and tube during intubation, etc., during training, thereby improving the effectiveness of the training. Furthermore, those skilled in the procedure can demonstrate exemplary procedures to beginners or less experienced observers in a blinded state, thereby improving the learning effect.

[0014] In the procedure training kits according to the first to third aspects of the present invention, the first and second colors may be any combination of colors, such as a combination of complementary colors, as long as they make it difficult to see the inside of the body of the biological model. Furthermore, the biological model may be any type that allows training in invasive procedures, such as needle manipulation (e.g., puncture), incision with a scalpel, and tracheal intubation. The biological model may be, for example, a commercially available simulator such as a puncture simulator, puncture model, or incision model, or may be a newly manufactured model.

[0015] Furthermore, in the procedure training kits according to the first to third aspects of the present invention, the invasive site and covering material of the living body model may be made of any material, such as acrylic resin or PVA (polyvinyl alcohol), as long as the material is transparent or semi-transparent and allows for invasive procedures such as needle manipulation (e.g., puncture), incision with a scalpel, and tracheal intubation. When made of resin, the movement of the needle or scalpel during training can be observed not only visually or photographed with a video camera, but also, for example, with an ultrasound diagnostic device (echo), thereby further enhancing the training and learning effects.

[0016] The procedural training kits according to the first to third aspects of the present invention may include goggles with a film made of the filter, or glasses or a camera with lenses made of the filter. In this case, for example, a trainee can easily conduct training by wearing the goggles or glasses. Furthermore, training in a practical clinical setting can be conducted blindly while viewing images captured by a camera with lenses made of the filter.

[0017] The procedural training method of the present invention is a procedural training method using the procedural training kits of the first to third present inventions, and is characterized in that the procedural technique is performed on the biological model while the biological model is viewed through the filter.

[0018] The procedural training method according to the present invention uses the procedural training kits according to the first to third aspects of the present invention, allowing the trainee to practice procedural skills without being blind. Furthermore, while the trainee is practicing procedural skills, the inside of the body of the biological model can be filmed using a video camera or the like, allowing the movement of the needle, scalpel, or other device during training to be visualized. This allows, for example, the video of the training to be fed back to the trainee, which is effective in helping the trainee master and improve their procedural skills.

[0019] According to the present invention, it is possible to provide a procedural training kit and a procedural training method that allow a person to visualise the movements while training in a procedural skill in a blind state.

[0020] 1 is a perspective view showing a procedure training kit according to an embodiment of the present invention.

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a procedure training kit and a procedure training method according to an embodiment of the present invention. As shown in Fig. 1, the procedure training kit 10 is used for training in procedures that involve invasiveness to a living body, such as needle manipulation, puncture, incision, insertion and placement of catheters, endoscopes, implants, treatment instruments, and medical instruments, or intubation, and includes a living body model 11, a covering 12, and goggles 13.

[0022] The biological model 11 mimics a part or the entire body of a living organism from its surface to its interior, allowing for visualization of the internal structure. The biological model 11 is made of a material that allows for invasive procedures, such as needle insertion, incision, and intubation, from the surface of the body into the interior of the body, enabling training in such procedures. In a specific example shown in FIG. 1 , the biological model 11 is for epidural anesthesia puncture training and is made of a thin, rectangular container 21 with an open top, containing a spine model 22, with gelatin 23 poured and solidified between the container 21 and the spine model 22 and on top of the spine model 22. The biological model 11 is formed so that the open side of the container 21 faces the body surface. Note that the biological model 11 is not limited to the one shown in FIG. 1 , and may be, for example, other puncture models, incision models, or various commercially available models or simulators.

[0023] The covering material 12 is a thin sheet, transparent or translucent, and colored a first color. The covering material 12 is formed to cover at least the body surface side of the biological model 11. When covering the body surface side of the biological model 11, the covering material 12 is made of a material that allows for invasive procedures such as needle insertion, incision, and intubation toward the inside of the biological model 11, thereby enabling training of procedures. In the specific example shown in FIG. 1 , the covering material 12 is made of PVA (polyvinyl alcohol), is transparent, and is colored red as the first color. Note that the covering material 12 is not limited to PVA, and may be made of any material, such as acrylic resin, as long as it allows for invasive procedures during training. The covering material 12 may also be somewhat thick.

[0024] The goggles 13 are made of a filter 24 made of a transparent or translucent film. The filter 24 is colored a second color so that when a trainee wears the goggles 13 and looks at the biological model 11 covered with the covering material 12, the inside of the body of the biological model 11 becomes difficult to see. In the specific example shown in FIG. 1 , the filter 24 is transparent and colored green as the second color, which is complementary to the first color. Note that the first and second colors may be reversed, and any color combination may be used, not limited to a combination of complementary colors, as long as it makes the inside of the body of the biological model 11 difficult to see.

[0025] Next, the operation will be described. The procedure training kit 10 can be used for training in procedures such as needle insertion, incision, or intubation. That is, the procedure training kit 10 allows a trainee to perform invasive procedures while viewing the biological model 11 covered with the covering material 12 through the filter 24 of the goggles 13, thereby enabling the trainee to perform the procedure blindly, without being able to see the inside of the biological model 11, just like in actual clinical practice.

[0026] Furthermore, when the biological model 11 of the procedure training kit 10 is viewed without the filter 24 of the goggles 13, the transparent or translucent covering 12 allows the inside of the biological model 11 to be seen. Furthermore, the inside of the biological model 11 can be seen from a portion of the biological model 11 that is not covered by the covering 12, such as the side of the biological model 11. Therefore, when a trainee is practicing a procedure, the visible inside of the biological model 11 can be captured as a video using, for example, a video camera, thereby visualizing the movement of the needle, scalpel, or other instrument during training. This allows the trainee to receive feedback on the video of the training, enabling the trainee to match the sensations felt during training with the actual movement of the needle, scalpel, or other instrument and to identify the cause of any failures, which is effective in mastering and improving the procedure.

[0027] Furthermore, an observer observing the trainee's training without looking through the filter 24 of the goggles 13 can also see the trainee's movements of the needle, scalpel, etc. This allows, for example, the observer to give advice to the trainee on the movements of the needle, scalpel, etc. during training, thereby improving the effectiveness of the training. Also, a person skilled in a procedure can blindly demonstrate exemplary procedures to a beginner or less experienced observer, thereby improving the learning effect.

[0028] In the procedure training kit 10, the invasive area of ​​the biological model 11 and the covering material 12 are made of gelatin 23, PVA, or the like, so that the movements of the needle, scalpel, etc. during training can be not only observed visually or photographed with a video camera, but also, for example, hard-to-see areas can be observed with an ultrasound diagnostic device (echo), further enhancing the effectiveness of training and learning. Furthermore, the procedure training kit 10 allows the trainee to easily perform procedure training by simply putting on the goggles 13.

[0029] The procedure training kit 10 may include glasses or a camera with lenses made of filters 24 instead of the goggles 13. In this case, the trainee can easily train the procedure by wearing the glasses. Furthermore, the trainee can also train the procedure blindly in an actual clinical setting while looking at an image captured by a camera with lenses made of filters 24.

[0030] Alternatively, the procedure training kit 10 may not include the covering material 12, and at least the surface or superficial layer of the biological model 11 on the body surface side may be colored with a first color. In this case, too, the trainee can perform invasive procedure training while viewing the biological model 11, at least the surface or superficial layer of which is colored, through the filter 24 of the goggles 13, and thus can perform procedure training in a blind state. In one specific example, by using gelatin 23 colored red by mixing food coloring in the biological model 11 shown in FIG. 1, procedure training can be performed in a blind state without the covering material 12.

[0031] Furthermore, in this case, since the colored surface or superficial layer of the biological model 11 is transparent or translucent, when the biological model 11 is viewed without looking through the filter 24 of the goggles 13, the inside of the body of the biological model 11 can be seen. Moreover, the inside of the body of the biological model 11 can also be seen from parts other than the colored surface or superficial layer of the biological model 11. For this reason, the movements of the needle, scalpel, etc. during training can be recorded as video using a video camera or the like, and the video can be fed back to the trainee, which is effective in mastering and improving the technique.

[0032] Using the biological model 11 shown in Figure 1 made of gelatin 23 colored red with food coloring and goggles 13 with a green film, the trainee performed the puncture procedure while wearing the goggles 13. A video camera was installed near the trainee to record video of the needle insertion and other procedures during training. In the training, after the needle tip reached the spinal canal, a catheter was inserted. An endoscope was also inserted into the spinal canal, and the needle and catheter were recorded.

[0033] As a result, the trainee was unable to see the spine during training. On the other hand, an observer not wearing goggles 13 could easily observe the needle movement and take video. In addition, by taking images of the inside of the spinal canal with an endoscope, the position and orientation of the needle tip that had reached the spinal canal and the insertion direction of the catheter could be observed.
