Japanese Patent No. 5649676 JP 2006-317635 A

  In the injection practice tool described in Patent Document 1, the mounting body is placed on a desk or the like and used, and since the size is constant, individual differences such as differences in arm thickness and realism are reproduced. Was difficult. Moreover, it was not possible to reproduce the angered state using the actual tourniquet.

  In the invention described in Patent Document 2, it is possible to reproduce the angered state using the tourniquet, but the internal pressure of the blood vessel is sufficiently increased only by tying the artificial blood vessel with the tourniquet. Therefore, it was difficult to reproduce a realistic state. In addition, since the appearance of the base and the like is formed of a soft member, if the practitioner is inexperienced, he / she may feel uneasy about whether he / she may pass through the base and pierce the pseudo worker's arm.

  In view of the above-mentioned drawbacks of the prior art, it is possible to practice in a state that reproduces a sense of reality such as individual differences and face-to-face implementation of pseudo employees, and to realize an injection practice tool that can further improve the practice effect It is a target invention.

  In the injection practice tool of the present invention, a simulated subcutaneous tissue layer is mounted on the upper surface of a mounting body that is vertically long and curved in the center in the width direction, and a simulated blood vessel is disposed on the simulated subcutaneous tissue layer. In the injection training device having a simulated skin layer disposed over the blood vessel and having an arm passage portion on the inside thereof, the mounting body made of a hard material has a curved projecting arc shape and a curved shape that changes the curved shape. A changing means is formed.

  Further, it is preferable that the bending changing means is provided with a plurality of bending grooves formed in the width direction formed in the longitudinal direction of the mounting body.

  Further, the upper cover having the simulated skin layer is attached to the attachment main body on one side so as to be freely opened and closed, and on the other side, swingable locking means for locking the opened and closed state is provided. It is preferable to have.

  The upper cover preferably has a tourniquet winding portion having a tourniquet through hole.

  The simulated blood vessel has a tubular shape with one end closed, the open end is formed of a flexible material, the simulated blood is connected to a sealed simulated blood bag, and the simulated blood is attached to one end of the mounting body in the longitudinal direction. A back housing portion for housing a bag is formed, and the simulated blood vessel is extended from the simulated blood bag housed in the back housing portion onto the simulated subcutaneous tissue layer. It is preferable to provide a presser that compresses the pressure, and the presser also serves as a tourniquet winding portion.

  Moreover, it is preferable that a plurality of back housing portions are arranged in parallel in the circumferential direction of the mounting main body at one end portion of the mounting main body, and the presser covers the entire upper surface of the one end portion.

  Moreover, it is preferable that the mounting body is detachable from a deck held in a curved salient shape.

  According to the first aspect of the present invention, the curvature of the mounting body attached to the arm can be appropriately changed and used. Because many parts other than the simulated skin layer and simulated subcutaneous tissue layer are made of hard resin, compared to the conventional training equipment worn on the arm, even if the practitioner is inexperienced, it can be used with confidence it can. Without having to pierce the simulated blood vessel, it is possible to practice with a sense of reality without worrying about passing through the attachment body and piercing the actual arm.

  According to the second aspect of the present invention, the bending changing means is formed, and the bending state of the mounting body can be changed according to the thickness of the arm to be wound.

  According to the invention described in claim 3, the upper cover can be stably locked. When the mounting body is used, this is slightly different in the arch state (curved state) in the front-rear direction (shrinks toward the wrist side). Therefore, in order to make it easier to engage the locking claw of the upper cover with the locked portion. It is preferable to swing and rotate the locked portion in the front-rear direction, so that the upper cover can be locked stably.

  The invention according to claims 4 and 5 makes it easy for the practitioner to grasp the position where the tourniquet is wound, and the tourniquet also serves as a presser for pressing the simulated blood bag. Wrapping can squeeze the simulated blood bag, enabling more realistic practice.

  According to the sixth aspect of the present invention, a plurality of simulated blood can be used, and all the simulated blood bags can be fixed with the presser.

  Further, according to the seventh aspect of the present invention, it is possible to make it detachable from a deck that can be used on a table, and it can be used both when used on a table and when it is wound around an arm.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an injection practice tool according to the present invention will be described with reference to the accompanying drawings. In this description, the longitudinal direction of the mounting body 1 is the front-rear direction, the left back side in FIG. 1 is the front side, and the right front side is the rear side. Moreover, the direction orthogonal to the longitudinal direction of the attachment main body 1 is made into the width direction, and the both sides of the width direction are demonstrated as a side.

  As shown in FIG. 1, the basic form of an injection practice tool according to the present invention is arranged on an attachment body 1, a simulated subcutaneous tissue layer 2 disposed on the upper surface of the attachment body 1, and a simulated subcutaneous tissue layer 2. Simulated blood bags 6 and 6 connected to the simulated blood vessels 3 and 3 for supplying simulated blood and an upper cover 5 for stretching a simulated skin layer 4 covering the simulated blood vessels 3 and 3 above.

  The mounting body 1 has a shape in which a substantially plate-like body made of a hard resin is curved into a salient arc shape and an arch shape as a whole. The inner side on the back side of the mounting body 1 having a projecting arc shape or an arch shape is opened, and the opened inner portion becomes the arm passage portion 51. The mounting body 1 can be used by being placed on a table while being attached to the base 40. However, as shown in FIG. 2, the mounting body 1 is detached from the base 40 and an arm passage portion 51 serving as an inner portion of the mounting body 1 is provided. It can also be used by wrapping around the arm 50 of the pseudo person.

  As shown in FIG. 2, when used by wrapping around the arm 50 of the pseudo person, the mounting body 1 is mounted by the mounting unit 20 at a position from the elbow joint of the arm 50 to the wrist side from the central side (shoulder side) 5 to 10 cm. (See FIG. 4). Then, the blood needle injection can be practiced by inserting an injection needle into the simulated blood vessel 3 from the surface (upper surface) of the simulated skin layer 4 while being attached to the arm 50. By attaching to the arm 50 of the pseudo person, it is possible to simulate blood vessel injection into the arm of the facing pseudo person, and to reproduce the individual difference of the pseudo person and the realism such as the face-to-face implementation.

  First, the configuration of the mounting body 1 will be described. The mounting body 1 uses a hard synthetic resin material such as ABS resin. By using the hard material in this way, when the practitioner uses it by mistake, not only the injection needle does not penetrate the mounting body 1 but also the simulated skin layer 4 and the simulated subcutaneous tissue layer 2 are excluded. Since the whole and the appearance are made of a hard material, it can be used with peace of mind even if injection practice is inexperienced.

  As shown in FIG. 3, the longitudinal length of the mounting body 1 (longitudinal length in FIG. 3) is a predetermined length from the general human elbow joint to the center side (shoulder side) from the elbow joint to the forearm. In this embodiment, it is 230 mm. The width direction length between both side insertion pieces 30, 30 formed on the left and right ends of the mounting body 1 is a predetermined length that is the thickness of the arm at a position from a general human elbow to the wrist. In this embodiment, it is 115 mm. The mounting body 1 is formed into a projecting arc shape and an arch shape as a whole by curving the central portion in the width direction into a projecting arc shape. The height of the apex that forms a salient arc from between the two insertion pieces 30 is about 45 mm.

  The mounting body 1 has standing pieces 31 and 31 with both front and rear ends in the longitudinal direction rising. On the surface of the mounting body 1, along the longitudinal direction, there are two bending grooves 27, 27 that are bending changing means from the front standing piece 31 to the rear standing piece 31. Notches 32 and 32 are formed by notching at the positions of the front and rear standing pieces 31 and 31 corresponding to the bent grooves 27 and 27. With the bent grooves 27 and 27 and the notches 32 and 32, as shown by the arrow lines Z and Z in FIG. The bending state can be changed. Thereby, it becomes possible to adjust the width | variety of the attachment main body 1, a curved state, and an arch state according to the thickness of the arm 50 of a pseudo | simulated person.

  The insertion pieces 30, 30 of the mounting body 1 are formed with support holes 33, 33 that support the mounting part 20 in the center, and the belt-like mounting parts 20, 20 are passed through the support holes 33, 33. To support. As shown in FIG. 4, one mounting portion 20 is provided with a locking portion 20a, and the other is a mounting portion 20 having a predetermined length and a locked portion 20b. The mounting main body 1 is wound around the arm 50 of the pseudo person, the locking portion 20a of the mounting portion 20 is locked to the locked portion 20b, and the arm 50 is tightened by the mounting portion 20, so that the mounting can be mounted on the arm 50. . The mounting body 1 can be bent in the circumferential direction by tightening the arm 50 by the mounting portion 20 and can be reduced in diameter according to the arm 50 to be mounted, and can easily follow the shape of the arm 50 to be mounted. , Can increase the sense of reality.

  As shown in FIG. 3, the surface side (upper surface) of the mounting body 1 has a mounting position A that is a portion recessed from the periphery so that the simulated subcutaneous tissue layer 2 can be detachably disposed. Specifically, it is between the front side step portions 11 and 11 of the mounting body 1 and the rear standing piece 31 and between the left and right side left and right step portions 34 and 34. The range in which the upper surface is covered with the simulated subcutaneous tissue layer 2 is wide enough to practice injection on the upper surface of the attachment body 1. The left and right step portions 34, 34 are formed with attachment holes 29, 29 on the front side, the center, and the rear side near the lower end thereof.

  Next, the simulated subcutaneous tissue layer 2 attached to the attachment position A of the attachment body 1 will be described. As shown in FIG. 5, the simulated subcutaneous tissue layer 2 is attached to the upper surface of the arched and arched plates 28 and 28 that match the curved shape of the upper surface of the mounting body 1. It consists of a low resilience foam material that reproduces the feel of the pseudo subcutaneous tissue. The low resilience foaming material is, for example, low foaming urethane, and Memory Foam (registered trademark) is preferable. The tips 28a, 28a of the plate bodies 28, 28 protrude from the left and right sides of the simulated subcutaneous tissue layer 2, and the simulated subcutaneous tissue layer 2 as a whole is inserted into the attachment holes 29 (see FIG. 3). Is detachable from the mounting body 1.

  Even if there is a change in the arch state (change in the curved state) of the mounting body 1 by mounting the simulated subcutaneous tissue layer 2 by inserting the plates 28 and 28 into the mounting holes 29 and 29 of the mounting body 1. It becomes possible to arrange the simulated subcutaneous tissue layer 2 appropriately. That is, when the simulated subcutaneous tissue layer 2 is simply pasted to the mounting position A of the mounting body 1, the surface of the mounting body 1 is changed when the arched form is changed by the bending grooves 27 and 27 and the notches 32 and 32. The simulated subcutaneous tissue layer 2 is peeled off or damaged due to the expansion and contraction. On the other hand, when attached to the plate bodies 28, 28, the plate bodies 28, 28 are curved and the tips 28a, 28a have a predetermined length even if the arch state of the attachment body 1 is changed. Therefore, it becomes possible to stably dispose the simulated subcutaneous tissue layer 2 by absorbing the elongation of the surface generated when the arch state is changed.

  Next, the upper cover 5 on which the simulated skin layer 4 is stretched will be described with reference to FIG. A simulated skin layer 4 covering the upper side of the simulated subcutaneous tissue layer 2 is stretched on an upper cover 5 disposed on the upper surface of the mounting body 1 (see FIG. 1). As shown in FIGS. 6 to 8, the upper cover 5 is formed in an arch shape that matches the curved shape of the upper surface of the mounting body 1, and the center portion thereof is cut off. The simulated skin layer 4 is stretched on the excised central portion.

  The simulated skin layer 4 is formed of a urethane-based material, and unlike the case of a silicon-based material, the dry state (wetting condition) of the disinfecting alcohol can be visually confirmed, and the dry skin is not sufficiently disinfected. Injection can be prevented. In addition, by using a urethane-based microcell polymer sheet, an undisinfected state can be confirmed from the expansion due to alcohol.

  The upper cover 5 is a lateral piece as a fixing means to the mounting body 1 at the side edge portion in the longitudinal direction, and is provided at two positions on the front and rear sides of the piece on the opposite side of the piece on which the locking claw 24 is formed. Are provided with key-like fitting protrusions 22, 22 facing outward. A fitting hole (not shown) for fitting the fitting protrusions 22, 22 is formed in the right side step portion 34 of the mounting body 1, and the upper cover 5 is attached to the mounting body 1 by these fittings. It can be attached detachably.

  In the piece where the fitting protrusions 22 and 22 of the upper cover 5 are formed, a fold line 9 (living hinge) is formed in the vicinity above the fitting protrusions 22 and 22 in the longitudinal direction. The entire upper cover 5 on which the simulated skin layer 4 is stretched by being bent along is made openable and closable toward the upper side of the mounting body 1. Then, the upper cover 5 covers the upper surface of the mounting body 1 to be in a pressed state, whereby an injection practice state in which the simulated blood vessel 3 exists under the simulated skin layer 4 can be realized.

  The upper cover 5 has four folding grooves 14, 14, 14, 14 formed in parallel in the longitudinal direction of the inner part where the simulated skin layer 4 is stretched. Then, the upper cover 5 is bent along the bending groove 14 to reduce the diameter of the upper cover 5, and the upper cover 5 follows the changed shape of the arched state of the mounting body 1 that has been reduced in diameter in accordance with the arm 50. Can be made.

  In order to lock the closed state of the upper cover 5 that can be opened and closed by the fitting protrusions 22, 22, a locking claw 24 and a covered cover are provided on the side opposite to the side where the fitting protrusions 22, 22 are provided. Locking means comprising the lock portion 25 is provided. This is because a claw-like locking claw 24 is formed on the upper cover 5, and a locked portion 25 (see FIG. 8) having a hook is formed on the mounting body 1. The state where the cover 5 is closed and the simulated skin layer 2 is pressed can be maintained.

  As will be understood from FIGS. 8 and 9, the specific form of the locked portion 25 is provided with a support shaft (not shown) protruding toward the mounting body 1 and a swing hole 21 (see FIG. 3) of the mounting body 1. ) Can be swung in the longitudinal direction of the mounting body 1 with the rocking hole 21 (support shaft) as a fulcrum. The locked portion 25 has an insertion portion 25a that is wider than the locking claw 24, and has a plurality of convex portions (hooks) that lock the locking claw 24 on the inner surface of the insertion portion 25a. Reference numeral 26 denotes a knob that deforms the insertion portion 25a to unlock the locking claw 24.

  This swinging facilitates the engagement when the attachment main body 1 is attached to the arm 50 of the pseudo person and the upper cover 5 is closed to engage the locking claw 24 and the locked portion 25. It is. That is, generally, a person's arm has a shorter circumference from the elbow portion to the wrist portion. When the arm passage portion 51 of the attachment main body 1 is inserted into the pseudo patient's arm 50 and tightened with the belt-like mounting portion 20 in the central portion of the attachment main body 1 in the longitudinal direction, the elbow side (shoulder side) becomes thick and the wrist side becomes Since it becomes thinner, the arched state is slightly different when hung in the front-rear direction (shrinks toward the wrist). Therefore, in order to easily engage the locking claw 24 of the upper cover 5 with the locked portion 25. It is preferable to rotate and swing the locked portion 25 in the front-rear direction, so that the upper cover 5 can be locked stably.

  Next, mounting of the simulated blood vessel 3 arranged on the mounting body 1 will be described (see FIG. 1). The simulated blood vessel 3 is supplied as a disposable together with the simulated blood bag 6. As shown in FIG. 10, the simulated blood bag 6 contains simulated blood in a bag (case) in the upper part of the drawing, and projects a cylindrical connecting portion 15 from the base end of the case toward the front. A blind cylinder-shaped simulated blood vessel 3 formed of natural rubber or the like is connected to the connecting portion 15.

  The simulated blood filled in the simulated blood bag 6 is colored red to give a sense of presence, and the simulated blood bag 6 and the entire simulated blood vessel 3 as a whole are sealed in a state where no air enters the inside including the simulated blood vessel 3. It is preferably sealed and packaged. By keeping the simulated blood bag 6 and the simulated blood vessel 3 in a state where air does not enter, it is possible to prevent bubbles mixed with liquid and air from entering the syringe when the practitioner punctures the needle. Further, by making the simulated blood bag 6 completely sealed, deterioration of the simulated blood bag 6 and the simulated blood vessel 3 made of natural rubber can be prevented. The simulated blood vessel 3 disposed on the simulated subcutaneous tissue layer 2 is preferably disposed in a straight line or a meandering state according to the skill of the practitioner.

  As shown in FIG. 3, a back accommodating portion 7 having a groove shape in the left-right width direction is provided between the plurality of step portions 11, 11 from the upright piece 31 on the front side of the mounting body 1. The back housing part 7 forms a plurality of installation parts 10, 10, 10 arranged in the width direction (left-right direction). By arranging the simulated blood bag 6 in the installation unit 10, a plurality of simulated blood bags 6 are pressed at once by the presser 8 by winding the tourniquet 16 when used later, and arranged in the installation unit 10. The simulated blood vessel 3 protruding from the simulated blood bag 6 can be appropriately disposed on the simulated subcutaneous tissue layer 2 (see FIG. 2).

  As shown in FIG. 1, on the front side of the mounting body 1, a step portion 11 is provided at the inner back (base end portion) of the back housing portion 7, and a slit is formed at a position aligned with the center of the installation portion 10 of the step portion 11. 12 so that the connecting portion 15 and the simulated blood vessel 3 can enter the slit 12. With this slit 12, the simulated blood bag 6 placed in the installation part 10 can be reliably set at a predetermined position in the back housing part 7, and the simulated blood vessel 3 can be properly positioned on the simulated subcutaneous tissue layer 2. .

  As shown in FIG. 6, a presser 8 for pressing the simulated blood bag 6 is disposed on the front side of the upper cover 5 and above the back container 7. The presser 8 is connected to the upper cover 5 through a thin portion 13 (living hinge) formed at the front center of the upper cover 5. As shown by the broken line in FIG. 11, the presser 8 is movable forward and downward by bending the thin portion 13, and the thin portion 13 is bent by winding a tourniquet 16 (see FIG. 2) described later. Thus, the simulated blood bag 6 can be pressed with the presser 8. A pressing projection 8a is provided on the bottom surface of the presser 8 so that the simulated blood bag 6 can be effectively pressed (see FIG. 1). The pressing protrusions 8 a, 8 a, 8 a are formed so as to protrude below the arc of the upper cover 5, and are positioned above the installation parts 10, 10, 10.

  With the above configuration, when the presser 8 is pushed downward, the pressing convex portion 8a presses the simulated blood bag 6 from above and raises the internal pressure of the simulated blood filled therein. This increase in internal pressure is the same for the simulated blood in the simulated blood vessel 3, and realizes a state similar to the actual anger state.

  As shown in FIG. 2, by tightening the presser 8 together with the arm 50 with the tourniquet 16, it is possible to practice the attachment of the tourniquet 16, and the simulated blood bag 6 is squeezed to keep the inner pressure constant. (Pressed state) can be maintained. In order to release the anger state, the presser 8 is returned upward by releasing the tightening state by the tourniquet 16 (relaxation by the presser 8 is released). And, by tightening the tourniquet zone 16, the presser 8 side in the longitudinal direction of the upper cover 5 may be deformed so as to be closer to the mounting body 1 than the other side. By locking the locked portion 25 against this deformation, locking between the locking claw 24 and the locked portion 25 can be maintained.

  By arranging the presser 8 above the plurality of installation portions 10, 10, 10, a plurality of simulated blood can be used, and the presser 8 can handle all the simulated blood. The names of blood vessels simulated by the simulated blood vessels 3 such as spruce cubs (scapular side veins) and shakusukuhi (ulcer side skin veins) or a part thereof may be written on the surfaces of the installation parts 10, 10, 10. In addition, the back blood storage portion 7 is formed widely, and the upper cover 5 is swingably locked, whereby the simulated blood bags 6 having different volumes can be arranged. For example, vacuum blood collection that requires a large amount of simulated blood can be practiced by disposing a large-capacity simulated blood bag 6 that is approximately twice as large as the conventional one. Further, the simulated blood bag 6 having different capacities may be a large-sized one that is disposed across a plurality of installation parts 10, 10, 10.

  The simulated skin layer 4 is perforated by use (practice). Therefore, it is preferable to replace the simulated skin layer 4 as appropriate. Therefore, by making the upper cover 5 detachable, for example, each practitioner owns only the upper cover 5 to practice without hesitation, and can share the mounting body 1.

  In order to attach the simulated skin layer 4 to the upper cover 5, the simulated skin layer 4 having a desired material and thickness is attached to the upper cover 5 using a double-sided adhesive tape or the like according to the skill of the practitioner. Moreover, the injection in the case of an edema state can be practiced by changing the simulated skin layer 4 to a thick one.

  As shown in FIG. 1, the mounting body 1 is preferably provided with a deck 40 having a flat bottom surface for placement on a desk or the like. The deck 40 is formed of a rectangular bottom plate, and a side end portion of the bottom plate has groove portions 41 and 41 for inserting and fixing both insertion pieces 30 and 30 of the mounting body 1 and is attached by engagement of these. The main body 1 is detachable from the deck 40. By attaching the attachment main body 1 to the deck 40, the attachment of the tourniquet 16 and blood vessel injection can be practiced without being attached to the arm 50.

  In the vicinity of both front and rear ends of the deck 40, holding portions 42 and 42 for holding the mounting body 1 are formed. By placing the lower surface of the mounting body 1 on the projecting arc-shaped and arch-shaped holding portions 42, 42, the mounting body 1 can be mounted on the deck 40 while maintaining the projecting arc state and the arched state. The holding portions 42 and 42 are formed with recesses 42 a and 42 a corresponding to the positions of the bending grooves 27 and 27 of the mounting body 1. The front and rear ends of the bending grooves 27 and 27 enter the recesses 42 a and 42 a, thereby preventing the mounting body 1 from being displaced while being held by the deck 40.

  Further, both front and rear end portions in the longitudinal direction of the deck 40 are formed in a semi-cylindrical shape by causing the central portion in the width direction to bulge into a projecting arc shape. The deck 40 has a shell shape that opens upward as a whole, and the mounting body 43 is formed by using the mounting body 1 as a lid. It is also possible to store an indwelling needle, a syringe, an injection needle, a tourniquet 16 and the like necessary for practice in the storage unit 43.

  In the position corresponding to the bag accommodating portion 7 of the mounting body 1, the deck 40 is formed with tourniquet through holes 52, 52 recessed inward on both sides thereof. The tourniquet through holes 52 and 52 are formed not only in the deck 40 but also in corresponding positions of the mounting body 1 and the upper cover 5. The tourniquet through holes 52 and 52 allow the tourniquet 16 to be passed around the arm when worn, enabling more realistic practice.

  In the upper cover 5, tourniquet through holes 52, 52 are formed at both ends in the width direction of the presser 8, and tourniquet through holes 52, 52 are also formed in the mounting body 1 and the deck 40. The person clearly indicates that the tourniquet through holes 52 and 52 and the presser 8 are wound around the tourniquet, so that the tourniquet 16 can be easily grasped and the tourniquet 16 can be easily grasped. Is easy to wind, and it is easy to maintain the wound state.

  In the present embodiment, the attachment main body 1, the upper cover 5, and the deck 40 are exemplified in which the tourniquet through holes 52 and 52 are formed, but the present invention is not necessarily limited to this form. For example, the tourniquet through holes 52 and 52 may be formed only in the attachment main body 1.

  The winding of the tourniquet 16 also serves as the presser 8, so that when the tourniquet 16 is wound, the presser 8 can press the simulated blood bag 6 to be in a compressed state. This reproduces the case where the tourniquet 16 is used when an actual injection is performed, so that more realistic practice is possible. In addition, the tourniquet through holes 52 and 52 can be used not only for the latex-like string shape but also for other shapes such as a belt-like tourniquet zone. You can practice with the tourniquet 16.
