Description

According to the present invention, when learning a patient after surgery in an on-campus exercise in nursing, a student or the like can be made into a simulated patient state that imitates an actual patient in a short time, and a wearable simulator having a high learning effect (hereinafter referred to as a wearable simulator). , Also called "simulator").

Prolonged bed rest after surgery has an unfavorable effect on various organs. For example, in the circulatory and respiratory system, a decrease in functional lung activity causes aerobic lungs and pneumonia, and in the circulatory system, a decrease in circulating blood volume and especially venous blood stagnation in the lower body cause pulmonary embolization. It may lead to serious postoperative complications such as illness. In the locomotor system, joint contracture and muscle atrophy of the limbs are applied, and in the skin, the sacrum, spine, ilium, and bare part are loaded, and hard objects such as bones press the skin. It becomes easy to cause decubitus formation in the loaded part. Therefore, early wake-up after surgery is important for prevention of postoperative respiratory complications, cardiovascular complications, pressure ulcers and muscle weakness.

Early getting out of bed is promoted by performing various movements at appropriate frequency and time according to the patient's situation, starting from passive exercise and automatic exercise with the assistance of a nurse, to changing positions, raising the head, and sitting. Will be done. In order to safely proceed with repeated exercises until getting out of bed and repositioning, the nurse observes the patient's general condition each time and the medical equipment connected to the patient (electrocardiogram telemeter, drainage bag, continuous stiffness). It is necessary to check the connection status of the epidural anesthesia set, etc.).

Observation of the patient's general condition is important to determine if he / she can safely get out of bed. Moving the body of a patient who has been in bed rest during surgery can be an exercise load for the patient, which may lead to increased wound pain, dyspnea, orthostatic blood pressure reduction, and these physical symptoms are out of bed. It leads to a decrease in motivation for. In addition, it is important to check the connection status of medical devices to prevent the drainage tube and epidural catheter from being removed from the insertion site and the sensor electrode of the ECG telemeter from peeling off when leaving the bed. Is. The nurse needs to confirm the insertion site such as the epidural catheter, the insertion length, the fixing method, etc., and pay the utmost attention so that these do not come off when the patient's body moves.

In the field of nursing, the target person is accurately targeted by changing the form of the exercise (hereinafter, also referred to as "nursing exercise") to a role-play format of a simulated patient (hereinafter, also referred to as "patient role") and a nurse role. It is known that the learning effect is higher than that of the case exercises on paper. Here, the simulated patient means a simulated patient played by a person who is not an actual patient. When nursing students learn the above-mentioned procedure for getting out of bed of a patient after surgery, an exercise using a simulated patient is also performed. In addition to students, volunteers and part-time workers play the role of patients. When students play a patient and a nurse, it is meaningful to be able to learn from both perspectives for one procedure because they can experience both the patient side and the nurse side. On the other hand, depending on the content of the exercise, it may be necessary to draw the wound directly on the abdomen of the student who plays the patient, or to fix the medical device directly on the skin with tape or the like, which may cause the skin to be exposed. In this case, the learning effect may be reduced due to a decrease in concentration due to shame toward other students, and therefore the content of the exercise in which the students are simulated patients may be restricted. In addition, when requesting a simulated patient from a volunteer or a part-time job, it may not be easy to secure the required number of patients. Therefore, in role-playing exercises, a method is desired in which the student can play the patient without feeling shame.

Japanese Unexamined Patent Publication No. 2015-25924

Mai Arisawa, 4 others, "Bulletin of Tokyo Kasei University", Tokyo Kasei University, Vol. 59 (2), March 1, 2019, p. 39-46

In Patent Document 1, as a method for reducing shame of a simulated patient, it is possible to prevent the skin from being exposed and remove the shame by wearing it directly on the skin, underwear, or through a T-shirt or the like. Patient suits are listed. This document has a size and shape that can cover at least the ventral side of the upper body of a simulated patient from the neck to the chest, abdomen, pelvis, and both thighs including both upper arms, and has an appearance and texture. A simulated patient suit that resembles genuine skin and is composed of an elastic sheet of resin is described.

This suit is intended to be worn by medical students, nursing students, etc. when conducting medical examination training such as inspection and auscultation, so it has excellent adhesion to the wearer, but it is expensive and for practice. It can be difficult to prepare a large number of suits. Further, since it is not easy to put on and take off due to the above-mentioned adhesion, it is difficult to change clothes promptly. Moreover, since it is made of an elastic material sheet made of resin, it is expected that it will be difficult to move and will be easily stuffy. In particular, when used in the hot and humid season such as the rainy season or summer, sweat tends to adhere to the inside of the suit, so there is a concern about hygiene, and the burden of maintenance such as cleaning and drying after each use is heavy. it is conceivable that.

Non-Patent Document 1 describes a postoperative patient simulation suit that does not require time to be attached and detached. The suit is designed to be large with an emphasis on ease of changing clothes. In addition, this suit has a specific technique by providing a wound directly on the abdomen of the suit, or by making a hole in a specific part of the suit and attaching an epidural catheter inserted in the hole with tape to fix it. It is a suit that assumes the rear state. In addition, synthetic leather is used as the material of the suit. In this document, there is a description that it was useful for imaging postoperative patients of students as a result of the exercises conducted using the simulation suit, but the lack of adhesion of the suit, the discomfort of the material, etc. As a result, problems such as the inability to imagine the patient's condition and the difficulty in changing clothes due to the epidural catheter being pulled out or entangled when the suit was put on and taken off were raised. In addition, since the material of the suit is synthetic leather, there are concerns about its use in the summer and hygiene as in Patent Document 1.

Therefore, it is required that the wearable simulator for simulated patients assuming a postoperative state not only does not expose the skin, but is also easy to put on and take off, and has excellent adhesion when worn. In addition, since the connection position of the wound and drainage tube differs depending on the disease and surgical procedure in the actual postoperative patient, the connection location of the wound and drainage tube can be set to any place on the suit surface according to the purpose of the exercise. It is desirable to be provided in. Further, since securing the number of simulators contributes to the improvement of learning efficiency and learning effect, it is also desired that the cost is low enough to allow multiple introductions and that the simulators can be used for a long period of time.

The present invention has been made in view of such a background, and in nursing exercises, when learning a postoperative simulated patient and a procedure for a simulated patient, it is possible to easily become a simulated patient, and the learning effect is high. The purpose is to provide a wearable simulator.

The wearable simulator of the present invention is a wearable simulator worn by a wearer as a simulated patient and used for nursing exercises, and the wearable simulator is a vest and one or a plurality of wires connected to the vest. A fixing portion for connecting to the vest is provided at the tip of the linear body provided with the shape and connected to the vest, and the fixing portion and the vest are detachable means for being attached to and detached from each other by facing each other. The attachment / detachment means provided on the vest is provided in a predetermined range at one or a plurality of places on the front surface of the vest, and the vest is made of mesh and can be adjusted according to the body shape of the wearer. It is characterized by having an adjusting portion.

The connection between at least one of the linear bodies and the vest is made via a connecting member that is in contact with each other, and the front surface and the back surface of the connecting member are connected to the fixing portion and the vest, respectively. It is characterized in that it is provided with removable means that can be attached and detached by interviewing each other.

The attachment / detachment means is characterized by being a hook-and-loop fastener.

The tip of at least one of the linear bodies is fixed in the fixing portion in parallel with the surface of the connecting member and in a predetermined direction.

The back surface of the vest has a back surface fixing portion provided in the vertical direction along the spine of the wearer, and the back surface fixing portion is characterized in that an epidural catheter can be installed internally.

The wearable simulator of the present invention is used for nursing exercises by a wearer who is a simulated patient, and includes a vest and one or more linear bodies connected to the vest, and the linear body connected to the vest. The tip of the vest is provided with a fixing portion for connecting to the vest, the fixing portion and the vest are provided with a detachable means that can be attached and detached by facing each other, and the attachment / detachment means provided on the vest is 1 or 1 on the front surface of the vest. Since the vest is provided in a predetermined range at multiple locations and has an adjustable part that can be adjusted according to the wearer's body shape, the procedure for the postoperative simulated patient and the simulated patient is learned in the nursing exercise. At the same time, it is possible to easily become a simulated patient without taking time to put on and take off. In addition, since the vest easily adheres to the body, the simulated patient can easily feel the tension received from the striatum at the time of changing the position, and the wearer can easily imagine the actual postoperative patient's condition. Furthermore, since the striatum can be connected to any place on the front of the vest, the postoperative state of various surgical procedures can be reproduced in a simulated patient with one simulator, and nursing exercises can be performed. Also, since the vest is made of mesh, it has excellent breathability and can be practiced for a long time. If all the linear objects and medical equipment connected to the vest are removed, the vest is hygienic because it is easy to wash and dry, and because it is not bulky, it is easy to secure a storage place and maintain the simulator. The management burden is light. Furthermore, since the mesh vest is inexpensive, it is easy to secure the number of simulators and contribute to the improvement of learning efficiency. Due to the above-mentioned various effects, a high learning effect can be obtained for both the patient role and the nurse role in the nursing practice.

The connection between at least one of the striatum and the vest is made via a connecting member that is in contact with each other, and the front and back surfaces of the connecting member are attached to and detached from each other by being in contact with each of the fixing portion and the vest. Since the removable means is provided, the linear body is less likely to be easily detached from the vest as compared with the case where the connecting member is not used. As a result, the progress of the exercise is less likely to be hindered, which contributes to the improvement of the learning effect. In addition, since the linear body and the connecting member can be removed from the vest together, the simulator can be easily attached and detached. As a result, the patient role can easily and quickly become a simulated patient, so that the time for changing clothes can be shortened and more time for the exercise itself can be secured.

Since the attachment / detachment means is a hook-and-loop fastener, each part can be easily attached / detached, and when the simulator is attached / detached, the linear body can be quickly changed without being entangled. In addition, when it gets dirty, it can be used for a long period of time without reducing the adhesive force of the attachment / detachment means even after washing or washing, so it is easy to maintain the number of simulators and maintain the learning environment. ..

Since the tip of at least one of the striatum is fixed in the fixing portion in parallel with the surface of the connecting member and in a predetermined direction, it is possible to reproduce a state close to the actual postoperative patient. can. Students can easily notice the restrictions on postoperative movements that patients actually feel and the points that they should be aware of when nursing, and can obtain a high learning effect.

The back of the vest has a dorsal fixation section provided longitudinally along the wearer's spine, which allows the epidural catheter to be placed internally so that the epidural catheter can be skin-fixed. You can also learn the position and method of. By reproducing the state where the epidural catheter is connected not only to the abdomen but also to the back, the patient role can learn further restrictions on movement, and the nurse role has more striatum connected to the patient. You can learn the precautions and difficulties of the case.

It is a front view (first embodiment) of the wearable simulator of this invention. It is a front view (second embodiment) of the wearable simulator of this invention. It is a top view of a vest and a connecting member. It is a top view of the outer surface of the vest in the open state. It is a rear view of the vest. It is an enlarged plan view of a fixed part. It is a perspective view of the simulator wearing state by the patient role.

An example of the wearable simulator of the present invention is shown below. The first embodiment will be described with reference to FIG. FIG. 1 is a plan view of a simulator 1 in which a nursing student can be a simulated patient by wearing clothes or on the skin in a nursing exercise at a university or a vocational school, as viewed from the front side. .. The simulator 1 can be suitably used for a nursing exercise assuming a situation in which a patient leaves the bed after surgery. The simulator 1 includes a vest 2 and a plurality of linear bodies 5 connected to the vest 2. Here, the drainage tube 5b of the drainage conduit and the drainage bag 3b capable of storing the drainage are collectively referred to as an abdominal drain. A lead wire 5a extending from the electrocardiogram telemeter 3a and a drainage tube 5b extending from the drainage bag 3b are connected to the best 2, and the lead wire 5a and the drainage tube 5b are collectively referred to as a linear body 5.

A fixing portion 8 for connecting to the vest 2 is provided at the tip of the linear body 5 on the side connected to the vest 2. Here, the tip of the lead wire 5a is referred to as a lead wire connection portion 8a, the tip of the drainage tube 5b is referred to as a drainage tube connection portion 8b, and the lead wire connection portion 8a and the drainage tube connection portion 8b are collectively referred to as a fixing portion 8. The fixing portion 8 and the vest 2 are provided with a hook-and-loop fastener as a detachable means 7 that is in contact with each other and can be attached and detached. Specifically, the fixing portion 8 has a surface that is in contact with the vest 2, and the surface that is in contact with the vest 2 is provided with a hook-and-loop fastener (not shown) that can be attached to and detached from the vest 2. Further, the vest 2 is provided with a hook-and-loop fastener included in the fixing portion 8 and a removable hook-and-loop fastener 7a. The hook-and-loop fastener 7a provided on the vest 2 is provided so as to cover the front surface of the vest 2 from the chest to the abdomen.

The vest 2 is a mesh vest using a polyester mesh fabric, and has an adjusting portion 9 that can be adjusted according to the wearer's body shape. Two adjusting portions 9 are provided on each of the left and right side portions of the wearer. The number of adjustment parts is not limited to two on each side of the body on the left and right, and the installation position, shape, and number can be freely selected as long as the vest is brought into close contact. By contacting and fixing the tip of the linear body in contact with the vest, the movement is suppressed and it is difficult to come off the vest. In addition, by fixing the lead wire connection portion 8a of the electrocardiogram telemeter and the drainage tube 8b to the front surface of the vest, which is flexible and has excellent adhesion, the wearer can obtain a feeling of discomfort close to what the patient feels. Is.

The attachment / detachment means provided on the vest can be provided at any position and in any size as long as it is provided in a predetermined range at one or a plurality of locations on the front surface of the vest. For example, the attachment / detachment means may be provided so as to cover a wide range from the chest to the abdomen as shown in FIG. 1, or may be provided only on the chest, only on the abdomen, or separately on the chest and abdomen. From the viewpoint of learning effect, it is preferable to cover the chest and abdomen together. As a result, the fixed portion can be fixed at an arbitrary position on the front surface of the vest, so that the striatum can be connected to a free place on the vest assuming various postoperative conditions. As a result, both the patient role and the nurse role can experience more postoperative conditions, and it is expected that the learning effect will be improved.

The attachment / detachment means is not limited to the above-mentioned hook-and-loop fastener and can be freely selected as long as it is a member that makes it possible to reversibly attach / detach two surfaces that face each other and face each other. For example, an easily peelable sheet or a snap button may be used. The hook-and-loop fastener is preferable because it can be joined on the surface, the joining force is unlikely to decrease even if it is repeatedly attached and detached, and it is easy to attach it to a vest or a fixed portion.

The type of hook-and-loop fastener can be selected from various types such as woven fabric, knitted fabric, and resin molding type. As the hook-and-loop fastener, it is preferable to use one in which only one of the male and female is not mixed on one side thereof. As a result, it is possible to prevent the same attachment / detachment means from being joined to each other when the simulator or the vest is attached / detached, so that it is possible to reduce the trouble of peeling off the joined attachment / detachment means when the simulator or the vest is worn again. As a method of attaching the attachment / detachment means to the vest or the fixing means, various methods such as ironing, adhesive, double-sided tape, and sewing can be freely selected. As a method of attaching the attachment / detachment means, it is preferable to use ironing, an adhesive, or double-sided tape in combination with sewing from the viewpoint of strength and durability required at the time of use.

The attachment / detachment means on the front surface of the vest may be punched at a predetermined position, size, and density. As a result, it is possible to improve the air permeability and the adhesion to the body, which contributes to the improvement of the learning effect. In particular, when a hook-and-loop fastener is selected as the attachment / detachment means and is provided so as to cover a wide range from the chest to the abdomen, the rigidity of the vest is increased, so that the adhesion to the body is reduced and the breathability is also deteriorated. It's easy to do. Therefore, the application of the punched surface fastener is effective in improving the adhesion of the simulator to the body and the air permeability.

The vest 2 is a one-size-fits-all, but since it is a mesh vest made of mesh fabric, it can be worn over the head and adjusted using the adjustment parts 9 on the left and right sides of the body, regardless of the wearer's body shape. , Can be in close contact with the body. The material of the mesh fabric is not particularly limited as long as it is soft, breathable, and easily adheres to the body. For example, plant fibers such as cotton and linen, animal fibers such as silk and wool, rayon and cupra, etc. You can choose from various materials such as recycled fiber, nylon, synthetic fiber such as polyester, acrylic and polyurethane, and other paper and metal. In particular, from the viewpoint of breathability, flexibility, adhesion to the body, and the like, a mesh fabric using plant fibers or synthetic fibers is preferable. Further, from the viewpoint of durability, synthetic fibers are more preferable, and nylon, polyester, polyurethane and the like are further preferable. The mesh fabric constituting the vest is not limited to one type, and a plurality of mesh fabrics having optimum functions may be combined according to the part. Here, the vest made of mesh means a vest in which a mesh fabric is used for a part or all of the vest.

A 3 cm × 12 cm rectangular wound portion display member 23 on which the wound portion 21 is displayed is attached to the surface fastener 7a on the front surface of the vest 2. A hook-and-loop fastener is provided on the surface of the wound display member 23 that comes into contact with the hook-and-loop fastener 7a so that it can be attached to and detached from the vest. The wound display member is not limited to the abdomen, but can be set to a predetermined size and position depending on the postoperative wound position assumed in each exercise and the patient's condition so that the postoperative wound condition and position can be recognized. Can be provided. The wound display member is not limited to the abdomen, but may be provided on the chest, the back surface, or the like. Further, the wound display member may or may not be used depending on the purpose. The material of the wound display member can be freely selected, and for example, a plain weave cloth, a twill weave cloth, various cloths such as mesh, and a resin plate can be used. The wound can be displayed by putting a photograph of the wound inside the transparent resin plate or printing the photograph of the wound directly on the surface of the resin plate. Further, the display of the wound portion is not limited to the photograph, and may be performed by a method of creating a simulated wound portion with a silicon material on a resin plate.

A second embodiment of the wearable simulator of the present invention will be described with reference to FIG. FIG. 2 is a plan view of the simulator 1'when the connection between the vest and a part of the linear bodies among the plurality of linear bodies is performed via the connecting member when viewed from the front side. In the simulator 1', the connection between the lead wire 5a', which is one of the plurality of lead wires extending from the electrocardiogram telemeter 3a, the drainage tube 5b'extending from the drainage bag 3b, and the front surface of the best 2 is set to each. This is done via the connecting member 4 that is interviewed. Here, the electrocardiogram telemeter 3a and the drainage bag 3b are referred to as a medical device 3. The lead wire 5a extending from the electrocardiogram telemeter 3a is directly connected to the hook-and-loop fastener on the front surface of the vest. A hook-and-loop fastener is provided on the front surface and the back surface of the connecting member 4 as a detachable means for attaching and detaching the fixing portion 6 and the vest 2 so as to be in contact with each other. Here, of the two surfaces of the connecting member 4, the surface that comes into contact with the fixing portion 6 is referred to as the front surface, and the surface that comes into contact with the best 2 is referred to as the back surface. Further, the means for attaching / detaching the connecting member is not limited to the hook-and-loop fastener as long as the two surfaces can be attached / detached, and various means can be selected as in the case of the attaching / detaching means provided on the vest or the fixing portion. ..

The fixing portion 6a of the conducting wire 5a'has a surface that comes into contact with the surface of the connecting member 4, and the surface that comes into contact with the connecting member 4 is provided with a hook-and-loop fastener (not shown) that can be attached to and detached from the surface of the connecting member 4. .. Further, on the surface of the connecting member 4, a hook-and-loop fastener included in the fixing portion 6a and a removable hook-and-loop fastener (not shown) are provided. Further, on the back surface of the connecting member 4, a surface fastener 7a provided on the front surface of the vest 2 and a removable surface fastener (not shown) are provided.

As described above, the medical device 3 is connected to the connecting member 4 through the linear body 5. As the medical device, one used in an actual medical field may be used, or a device imitating the medical device may be used instead. In the form shown in FIGS. 1 and 2, the medical device is connected to the vest via a linear body, but as another form, if the linear body and the vest are connected, the medical device or its vest is connected. Substitutes (hereinafter referred to as "medical devices, etc.") may not be present. In order to obtain the learning effect of nursing exercises, at least a striatum must be connected to the vest. As a result, the practitioner can learn the shape, number, connection position, and the like of linear bodies such as drainage tubes and conductors. When using a medical device or the like, the electrodes of the electrocardiogram telemeter are connected via a vest, so that the electrocardiogram of the wearer of this simulator cannot be monitored. Therefore, it is preferable to substitute a small box or the like for the electrocardiogram telemeter. From the viewpoint of learning effect, it is preferable to use the conductors, conductor connections, abdominal drains, etc. of the electrocardiogram telemeter that are used in the actual medical field. In addition, the exercise may be performed with the pseudo blood in the drainage bag.

On the connecting member 4 provided on the abdomen of the vest 2, the wound portion 21 is displayed so that the state and position of the wound portion after the operation can be conscious. The connecting member is not limited to the abdomen, but can be provided at a predetermined size and position depending on the position of the wound after the operation assumed in each exercise and the condition of the patient. In addition, the display of the wound part may or may not be performed depending on the purpose. The position where the connecting member is provided is not limited to the abdomen, but may be provided on the chest or the back surface.

The size of the connecting member may be, for example, a shape that widely covers the chest, the lower abdomen, and the flanks. Further, the connecting member may be provided separately for each part of the body such as the chest, abdomen, and flank. The material of the connecting member can be freely selected, and for example, a plain weave cloth, a twill weave cloth, various cloths such as mesh, and a resin plate can be used.

As described above, the connecting member may have a function as a wound display member as well as for connecting the fixed portion by providing the wound portion on the surface. In that case, as the main body of the connecting member, one in which a photograph of the wound is placed inside a transparent resin plate or one in which a photograph of the wound is printed directly on the surface of the resin plate can be used. When a resin plate is used, it is possible to reduce the weight and improve the air permeability by performing a plurality of holes in the plate and forming it into a mesh. Further, in this case, since the rigidity of the resin plate is lowered, the adhesion to the body when wearing the vest to which the connecting member is joined is improved, and it becomes easy to obtain a natural wearing feeling.

When a plurality of linear bodies are connected to the vest, it is preferable that at least one linear body is connected to the vest via a connecting member from the viewpoint of the connection strength between the vest and the linear body. Since the presence of the connecting member between the vest and the fixing portion at the tip of the linear body, the tension can be relaxed by a plurality of attaching / detaching means, and the concentration of the force on one attaching / detaching means is suppressed. The linear body is more difficult to come off.

Next, the best 2 and the connecting member 4 used in the simulator will be described with reference to FIGS. 3A to 3C. FIG. 3A is a front view showing the surface of the best 2 in a state where the linear body and the connecting member are removed. Further, FIG. 3B is a plan view of the back surface of the connecting member 4. FIG. 3C is a plan view of the surface of the connecting member 4.

A hook-and-loop fastener 7a that comes into contact with the connecting member is attached to the abdomen of the vest 2 (see FIG. 3A), and a hook-and-loop fastener 7b that comes into contact with the hook-and-loop fastener 7a is attached to the back surface of the connecting member 4 (see FIG. 3A). See FIG. 3 (b)). Further, a hook-and-loop fastener 7c that comes into contact with the conductor connecting portion is attached to the surface of the connecting member 4, and a hook-and-loop fastener 7d that comes into contact with the drainage tube connecting portion is attached (see FIG. 3C). A surface fastener that comes into contact with the surface fastener 7c and the surface fastener 7d is attached to the lead wire connection portion and the drainage tube connection portion, respectively (not shown). Here, the surface fastener 7a, the surface fastener 7b, the surface fastener 7c, and the surface fastener 7d are referred to as the attachment / detachment means 7.

In this way, by providing the attachment / detachment means on the surface where each member comes into contact, each member can be reversibly attached / detached. As a result, it is possible to freely select whether to remove it between the vest and the connecting member or between the connecting member and the linear body, so that it can be attached and detached according to the situation, which is excellent in convenience during exercises. For example, the fact that the linear body can be removed from the connecting member means that various linear bodies and medical treatment can be performed with one simulator as compared with the case where the linear body is directly fixed on the suit as in Non-Patent Document 1 described above. It is useful because various exercises can be performed using equipment. In addition, when the same exercise content is performed while the patient roles take turns one after another, the striatum can be removed together by removing it between the vest and the connecting member. As a result, it is possible to prevent the striatum from coming off or getting entangled, and it is possible to change clothes easily and quickly.

The attachment / detachment means can be provided at any position on the surface of the connecting member and in any size. For example, as shown in FIG. 3D, the hook-and-loop fastener 7e may be provided on the entire surface of the connecting member 4'at a place other than the place where the wound portion 21 is displayed. As a result, the fixed portion can be fixed at an arbitrary place on the connecting member, so that the medical device can be connected to a free place assuming various postoperative states. As a result, it is expected that the learning effect will be improved by gaining more experience on both the simulated patient side and the nurse side. Here, the hook-and-loop fastener 7e is referred to as the attachment / detachment means 7.

The best adjusting portion will be described with reference to FIG. 4 (a). FIG. 4A is a plan view of the outer surface with the vest open. The vest 2 has an adjusting unit 9 whose size can be adjusted according to the wearer's body shape. The adjusting portion 9 is composed of an adjusting band 9a, an adjusting band 9a, and a detachable adjusting band fixing portion 9b. Two adjustment bands 9a are provided on each of the left and right sides of the wearer so as to be located on the waist and flanks. The moderator band 9a extends from the front side of the vest to the left and right, and is provided so as to reach from the flank to the back. The adjustment band fixing portion 9b is provided on the back surface of the vest so as to be in contact with the adjustment band 9a and to be fixed as a pair. Hook-and-loop fasteners are provided on the surfaces of the adjusting band 9a and the adjusting band fixing portion 9b that come into contact with each other, so that the adjusting band 9a and the adjusting band fixing portion 9b can be fixed reversibly. A piping portion 12 made of a twill cloth is provided on the edge of the main body of the vest 2. The moderator band 9a is also a twill cloth, and the best 2 is a mesh cloth.

The adjusting unit 9 is not limited to the above-mentioned hook-and-loop fastener, and any fixing means that can be reversibly fixed can be freely selected. As the fixing means other than the hook-and-loop fastener, for example, a button, a snap button, a fastener, or the like can be selected. As these fixing means, only one means may be used, or a plurality of means may be combined. A hook-and-loop fastener is suitable as the fixing means from the viewpoints of adhesion, fixing force, and easy attachment / detachment. More adjustment parts may be provided in order to ensure the adhesion to the wearer's body. For example, by providing it at three places, the waist, the flank, and the lower armpit, it is possible to further improve the adhesion not only to the abdomen but also to the entire upper body including the chest and the back.

Next, an example of the best using different materials will be described with reference to FIG. 4 (b). FIG. 4B is a plan view of the outer surface of the best 2'composed of fabrics made of different materials in an open state. A jersey material is used for the adjustment band 10a and the shoulder portion 11 of the vest 2', and a mesh material is used for the other parts. A piping portion 12 made of a twill cloth is provided on the edge of the vest 2'main body, and a jersey material is used for the piping portion 12'around the shoulder portion 11.

Since the jersey fabric part is more elastic than the mesh fabric part, the combined use of the jersey material fabric and the mesh fabric can improve the comfort and adhesion of the vest. In addition, when the simulated patient (best wearer) changes his / her position due to the movement of getting out of bed, it is possible to prevent the adjustment portion from coming off, and it is possible to maintain the close contact. Further, in the moderator band 10a in which the jersey material is used, it is preferable that the fixing means is provided at the tip of the moderator band. This makes it possible to maximize the stretching effect of the jersey material.

FIG. 7 shows a perspective view of the upper body of the patient role while wearing the simulator shown in FIG. 1 (the wound display member is omitted). The patient role wears a simulator on top of a T-shirt. 7 (a) is a perspective view from an oblique front, and FIG. 7 (b) is a perspective view from an oblique rear. As shown in FIG. 7, since the vest is in close contact with the chest, abdomen, and back of the wearer's upper body, it is close to what the patient actually feels as an attractive force from the striatum when changing the position. It is possible to get a sense of discomfort. As a result, the patient role can obtain a high learning effect.

An epidural catheter or the like may be connected to the back surface of the vest in addition to the above-mentioned linear body such as a drainage tube or a conducting wire. For the actual postoperative patient, tape the epidural catheter from the back of the waist to the back of the neck so that the patient in sleeping clothes or the nurse can operate the continuous epidural anesthesia set. Will be done. As an example of the back surface of the vest, the back surface of the vest 2 to which the continuous epidural anesthesia set 14 is connected will be described with reference to FIG. FIG. 5A is a plan view of the back surface of the vest 2 to which the continuous epidural anesthesia set 14 is connected via the back surface fixing portion 13. Further, FIG. 5B is a plan view of the back surface of the best 2 with the back surface fixing portion 13 and the adjustment band 9a open.

The back fixing portion 13 is provided with a hook-and-loop fastener inside, and can be opened and closed laterally with respect to the spine. Further, a connecting portion 16 for connecting the epidural catheter 15 extending from the continuous epidural anesthesia set 14 is provided on the lower back of the back fixing portion 13. The back surface fixing portion 13 may be directly sewn to the vest 2 and fixed, or may be fixed by a removable member such as a hook-and-loop fastener. In bed-leaving exercises, a continuous epidural anesthesia set is often connected to the back of the patient, and when fixed with a detachable member on the back, the back is affected by frictional force with the bed due to the change of position of the patient. When the back fixing portion is provided, it is preferable to sew it directly to the vest and fix it because the fixing portion may come off.

By connecting a continuous epidural anesthesia set to the back of the vest via a dorsal fixation, an epidural catheter can be extended from behind the waist to the back of the neck along the spine. In the actual postoperative condition, the epidural catheter inserted into the spinal cord from the back of the waist is fixed to the patient's back with tape from the waist to the back of the neck along the spine, and the epidural catheter from the back of the neck. Is in a stretched state. Therefore, by making the back surface of the vest the above configuration, it is possible to reproduce a situation close to the actual postoperative situation, and a high learning effect can be obtained.

From the viewpoint of the connection strength between the vest and the epidural catheter, it is preferable that the tip of the epidural catheter is connected to the connecting portion inside the dorsal fixation part and is connected to the vest via the backside fixing part. .. When the epidural catheter is directly attached to the back of the vest with tape from the back of the waist to the back of the neck without using the back fixing part, the adhesion area is small due to the unevenness of the fabric surface of the vest, so the adhesion is strong. It becomes low and sufficient connection strength cannot be obtained. On the other hand, when the dorsal fixation part is used, the tip of the epidural catheter is connected to the connecting part inside the backside fixing part, and the linear part is only inscribed in the backside fixing part, so that the epidural catheter is used. Since a certain degree of freedom is given to the movement of the epidural catheter, it becomes difficult for the epidural catheter to come off even if tension is generated during the change of position. This makes it easier for the exercises to proceed smoothly, which contributes to improving the learning effect. Further, in the above configuration, since the epidural catheter can be easily removed from the vest, it does not take time to wash the vest. This is preferable because the simulator can be used for a long period of time.

Regarding the fixing portion 6b in FIG. 2, an example of a means for connecting to the fixing portion at the tip of the linear body will be described with reference to FIG. FIG. 6 is a plan view of a state in which the tip of the drainage tube 5b (linear body) is connected to the drainage tube connecting portion 6b (fixing portion 6) by using the connecting portion 17. It should be noted that this state indicates a state in which the drainage tube connecting portion 6b is opened when the drainage tube 5b is removed. The drainage tube connecting portion 6b is provided with a hook-and-loop fastener 22a and a hook-and-loop fastener 22b that can be joined to each other inside, and can be folded in half and opened / closed. When the hook-and-loop fastener 22a and the hook-and-loop fastener 22b are joined to close the drainage tube connecting portion 6b, the tips of the connecting portion 17 and the drainage tube 5b are housed inside the drainage tube connecting portion 6b. The drainage tube connecting portion 6b is provided with an annular body 20, and a lobster hook 19 is connected to the tip of the drainage tube 5b via the annular body 18. Here, the above-mentioned annular body 18, lobster hook 19, and annular body 20 are collectively referred to as a connecting portion 17. Since each member of the connecting portion 17 is made of metal, a predetermined connecting strength can be secured.

The annular body 18 penetrates and is connected to the tip of the drainage tube 5b. Further, the annular body 20 penetrates and is connected to the surface fastener 22a inside the drainage tube connecting portion 6b. By connecting the lobster hook 19 connected to the annular body 18 and the annular body 20, the tip of the drainage tube 5b can be connected to the drainage tube connecting portion 6b, and the drainage tube can be prevented from coming off the vest during nursing exercises. can. Further, by connecting the drainage tube 5b to the drainage tube connecting portion 6b by the connecting portion 17 and further closing the drainage tube connecting portion 6b, the tip of the drainage tube 5b is parallel to the surface of the connecting member and is predetermined. Can be fixed in the direction of. As a result, the drainage tube can be fixed to the patient's body with the tape and can be brought into a state close to a situation in which the drainage tube is stretched in a predetermined direction, as in the actual postoperative period. Further, since the drainage tube 5b is fixed in a state of being sandwiched between the hook-and-loop fastener 22a and the hook-and-loop fastener 22b, the floating of the tip is suppressed. As a result, the drainage tube 5b is less likely to come off the vest than when it is simply connected to the connecting portion 17.

The connecting portion can also be applied to the connecting portion of the back fixing portion provided on the back surface of the vest described above. When the tube diameter of the epidural catheter is small, the tip of the epidural catheter may be directly connected to the annular body on the back fixed portion side without using a lobster hook or the like.

Next, a method of putting on and taking off the wearable simulator will be described. This simulator can connect multiple linear bodies to the vest, but if the wearer tries to put on and take off with the linear bodies connected, the linear bodies will get in the way and it will be troublesome to put on and take off. It takes time. In particular, care must be taken because the fixture may be damaged or the linear body may be entangled if it is forcibly attached or detached. If the caregiver can assist the wearer in putting on and taking off, the striatum is unlikely to get entangled, so that the striatum can be put on and taken off while being connected to the vest. As a result, the time required for putting on and taking off can be shortened.

It is preferable to follow the procedure below when attaching and detaching. First of all, wear only the vest with no striatum connected, and adjust the adjustment part to bring the vest into close contact with the body. After that, by connecting the linear body to the vest, problems such as breakage and entanglement of the linear body can be prevented. In addition, when taking off the simulator, contrary to the case of wearing, the procedure is to first remove the striatum and then take off the vest, so that the simulator can be taken off smoothly. If there are few striatum connected to the vest, or if you are accustomed to changing clothes, you can put on and take off the vest with the striatum still connected if you pay attention to the entanglement of the striatum.

If the striatum is connected to the vest via a connecting member, the striatum may be removed from the vest by removing the fixation at the tip of the striatum from the connecting member. Alternatively, the linear body and the connecting member may be removed from the vest together by peeling off the connecting member and the vest while the linear body is connected to the connecting member. By removing the linear body and the connecting member together from the vest, the entanglement of the linear body is suppressed, so that handling becomes easy. As a result, the simulator can be easily put on and taken off, and the clothes can be changed quickly.

The wearable simulator of the present invention can easily become a simulated patient when learning a postoperative simulated patient and a procedure for the simulated patient, and contributes to improving the learning effect of nursing students. Widely available for nursing practice in.
