Description

[Technical Field]

[0001] The present invention relates to an auxiliary tool for injection used during injection. [Background technology]

[0002] Conventionally, many people feel uneasy or disgusted by the visual appearance of a syringe with a needle and the act of inserting the needle into the body. Particularly when the recipient of an injection, such as a vaccination, is a child, the child often cries out of fear of the syringe and the injection, preventing the injection from proceeding smoothly. In response to this, for example, Patent Document 1 proposes a configuration in which a cylindrical cover is attached to a syringe to completely cover and conceal the needle.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-156954 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the above-mentioned conventional technology, the syringe itself and the act of pressing it against the subject's arm are visible to the subject, which alone can cause great fear. However, if the syringe is simply hidden from view by, for example, blindfolding the subject, a great shock is given at the moment of injection, imposing a great psychological burden on the subject.

[0005] An object of the present invention is to provide an aid for injection work that can significantly reduce the fear and mental burden of an injection recipient regarding the injection work. [Means for solving the problem]

[0006] In order to achieve the above object, the injection aid of the present invention is characterized by having a shielding portion that, when placed near the arm of a person to be injected, shields the injection operation into the arm from the visual field of the person to be injected, a contact portion provided on the shielding portion so as to be able to come into contact with and separate from the arm, and a pattern displayed on at least one of the shielding portion and the contact portion to express the inevitability of the contact portion coming into dynamic contact with the arm. [Effects of the Invention]

[0007] According to the present invention, the fear and mental burden felt by the person receiving the injection can be significantly reduced. [Brief explanation of the drawings]

[0009] An embodiment of the present invention will be described below with reference to the drawings. Note that the embodiment described below is for illustrative purposes only and does not limit the technical scope of the present invention. Therefore, a person skilled in the art may adopt an embodiment in which each of the following components is replaced with an equivalent, and such an embodiment is also within the technical scope of the present invention. In addition, in the following description, explanations of unimportant well-known technical matters will be omitted or simplified as appropriate to facilitate understanding of the present invention.

[0010] <Schematic configuration of the injection assisting tool according to this embodiment> 1(a) and 1(b) are perspective views showing the schematic configuration of an injection aid according to this embodiment, from the front and back, respectively. Injection aid 1 is a medical aid placed between an injection recipient, such as a child, whose arm is to be injected for vaccination (see FIGS. 3 and 4, described below), and an injection worker, such as a doctor (not shown). Injection aid 1 has a shielding portion 2, a contact portion 3, and legs 4. Note that the directions of front, back, top, bottom, left, and right shown in FIG. 1 are based on the directions as seen from the injection recipient's perspective, and will be commonly referred to in the following drawings.

[0011] The shielding part 2 is a generally rectangular flat wall having an appropriate large area, and is tilted at a predetermined angle toward the back. A rectangular insertion opening 21 is formed in the center of the lower side of the shielding part 2, through which the arm of the person to be injected can be inserted.

[0012] The contact portion 3 penetrates the inside of the shielding portion 2 in the vertical direction as will be described later, and is provided so that its lower end portion can be moved up and down inside the insertion opening 21 by manual operation by a separate worker.

[0013] The legs 4 are integrally provided on both sides of the lower portion of the shielding part 2, sandwiching the insertion opening 21, and support the shielding part 2 so that it can stand on its own while maintaining the above-mentioned tilt angle.

[0014] In addition, in the example of this embodiment, a pattern 5 representing the face of an ogre is displayed on the surface of the front side of the shielding part 2, and the insertion opening 21 corresponds to the ogre's mouth, and the lower end of the contact part 3 located inside it is represented as the ogre's upper row of teeth.

[0015] FIG. 2 is a perspective view showing the entire configuration of the injection aid 1, exploded into detailed components, from the same perspective as FIG. 1(b). In FIG. 2, the shielding portion 2 has a front wall portion 22, two middle wall portions 23, and a rear wall portion 24. The front wall portion 22 is a thin-walled plate formed in an inverted U shape surrounding the insertion opening 21 located at the center of its lower side. The middle wall portions 23 are thin-walled plates of a size and shape that overlap two regions of the front wall portion 22 that sandwich the insertion opening 21 on both sides, and are fixedly attached to the rear surface of the front wall portion 22. The rear wall portion 24 is a thin-walled plate formed in a rectangular shape with a width dimension W2 wider than the width dimension W1 of the insertion opening 21 and a length dimension H2 shorter than the stopper spacing H1 described below, and is fixedly attached across the rear surfaces of the two middle wall portions 23.

[0016] The contact portion 3 has a contact main body 31 and two stoppers 32. The contact main body 31 is a thin-walled plate formed in a generally rectangular shape with a width W1 equal to the horizontal dimension W1 of the insertion opening 21 and a vertical dimension sufficiently longer than the vertical dimension H2 of the rear wall 24. Stoppers 32 are attached to the rear surface of the contact main body 31 at two locations: the upper end position and a relatively lower midway position. The vertical distance H1 between the two stoppers 32 is set to be sufficiently longer than the vertical dimension H2 of the rear wall 24. In the illustrated example, as described above, the lower end of the contact main body 31 resembles the upper teeth of a demon, and five protruding portions 33 are formed, each with a sharply pointed tip facing downward.

[0017] The leg 4 has two bottom walls 41 and two support parts 42. The two bottom walls 41 are thin walls that are integrally formed at the inclination angle from the lower end portions on both sides of the front wall 22. The two support parts 42 are fixed so as to span between the back surface of each middle wall 23 and the upper surface of each bottom wall 41, maintaining the inclination angle therebetween. As a result, when the injection aid 1 is placed on a desk, for example, the lower surface of each bottom wall 41 comes into surface contact with the desk surface, and each support part 42 maintains its position at the inclination angle, allowing the injection aid 1 to be placed stably.

[0018] Furthermore, since the two middle wall portions 23 and the contact main body portion 31 disposed therebetween have the same thickness dimension, the entire contact portion 3 is inserted into the shielding portion 2 so as to be movable in the vertical direction. The length of movement is the difference (H1-H2) between the stopper interval H1 and the vertical dimension H2 of the rear wall portion 24. The range of movement is set so that the protruding portion 33 (the upper row of teeth of the demon) at the lower end of the contact main body portion 31 is always visible within the insertion opening 21.

[0019] <How to use the injection aid> The manner of use of the injection aid 1 of this embodiment configured as described above will be described with reference to Figures 3 and 4. First, before use, as shown in Figure 3, the front surface of the injection aid 1 is positioned toward the person to be injected so that the person can see the demon's face design 5 displayed on the front surface of the shielding part 2. The upper end of the contact part 3 is pulled upward, and the arm 100 of the person to be injected is inserted deeply into the insertion port 21, which is in the widest open state. At this point, the contact part 3 is not in contact with the person's arm 100, so free insertion is possible without any particular stimulation.

[0020] During the injection procedure, as shown in Figure 4, the shielding part 2 can shield the presence of the syringe 200 at the back and the act of bringing it closer to the recipient's arm 100 from the recipient's visual field, significantly reducing the anxiety and fear felt by the recipient. When actually injecting the syringe 200 into the arm, the operator or a separate assistant manually lowers the contact part 3 downward, and the tip of one of the protruding parts 33 provided at the lower end of the contact part 3 downward comes into contact with the arm 100 to provide a moderate stimulation to the recipient.

[0021] At this time, it is desirable to bring the contact portion 3 into contact with the arm 100 just before the injection needle is inserted into the arm, and it may also be made to make intermittent contact by repeating up and down movements for an appropriate period of time thereafter. It is also desirable that the strength of the contact be the same as or slightly weaker than the stimulation felt when the injection needle is inserted into the arm. This allows the recipient to focus their attention on the virtual sensation of being bitten by the ogre's mouth, greatly reducing and distracting them from the sensation of the actual injection procedure. Particularly when the recipient is a child, the anxiety associated with the virtual situation of being bitten by the ogre in design 5 takes priority, allowing them to forget their realistic fear of the injection procedure.

[0022] <Effects of the embodiment> As described above, the injection aid 1 of this embodiment has a shielding part 2 that, when placed near the arm 100 of the person to be injected, shields the injection operation on the arm from the visual field of the person to be injected, a contact part 3 that is provided on the shielding part 2 so that it can move toward and away from the arm 100, and a pattern 5 of a demon's face that is displayed on the shielding part 2 and expresses the inevitability of the contact part 3 coming into dynamic contact with the arm 100.

[0023] As a result, the shielding portion 2 can shield the presence of the syringe 200 located further back and the act of bringing it closer to the recipient's arm 100 from the recipient's visual field, significantly reducing the anxiety and fear felt by the recipient. When actually injecting the syringe 200 into the arm, an operator can manually bring the contact portion 3 into contact with the arm 100 to provide a moderate level of stimulation to the recipient. This allows the recipient to focus their attention on the virtual sensation of being bitten by the ogre's mouth, significantly reducing and distracting them from the sensation of the actual injection procedure. Particularly when the recipient is a child, the anxiety associated with the imaginary situation of being bitten by the ogre depicted in the image 5 takes priority, allowing the recipient to forget their realistic fear of the injection procedure. As a result, the fear and psychological burden felt by the recipient regarding the injection procedure can be significantly reduced.

[0024] In particular, in this embodiment, the shielding part 2 has an insertion opening 21 through which the arm 100 is inserted. This allows the injection recipient to easily position the shielding part 2 near the arm 100 in the correct positional relationship by simply inserting the arm 100 through the insertion opening 21.

[0025] Furthermore, particularly in this embodiment, the shielding part 2 has legs 4 that allow the shielding part 2 to stand on its own. As a result, when using the injection operation aid 1, there is no need for a separate operator to hold it in their hands and place it near the arm 100 of the person to be injected; for example, the shielding part 2 can stand on its own via the legs 4 on a desk or the like, and the person to be injected can easily insert their arm 100 into the insertion port 21.

[0026] Furthermore, particularly in this embodiment, the contact portion 3 has a protruding portion 33 whose tip forms an acute angle and comes into contact with the arm 100. As a result, by bringing the protruding portion 33 of the contact portion 3 into contact with the arm 100, it is possible to give the injection recipient a stimulus similar to that experienced during an injection, thereby significantly reducing and distracting from the stimulus caused by the actual injection procedure. Note that it is sufficient to have one or more protruding portions 33, and a pattern may also be displayed on the contact portion 3.

[0027] Furthermore, particularly in this embodiment, the design 5 is depicted so that the contact portion 3 is in contact with the arm as if it were part of a living creature. This allows the recipient to psychologically perceive the stimulation given to the arm 100 as being given by the imaginary action of a living creature, rather than by the injection needle. Therefore, particularly when the recipient is a child, the anxiety about the imaginary situation of being bitten by the living creature depicted in the design 5 takes precedence, which is expected to have the effect of making the recipient forget the realistic fear of the injection procedure.

[0028] The design is not limited to the face of a demon as in the above embodiment, and various other designs are applicable, such as a design 6 of a bee virtually pricking the arm 100 with a needle as shown in Fig. 5. Any other design may be used as long as it shows a situation in which a stimulus is being applied to the arm 100, and although not shown, it is particularly effective for children to display designs with motifs of little boys and girls, other animals, monsters, vehicles such as cars, or popular characters.

[0029] Furthermore, although not specifically shown, the shielding portion 2 may be equipped with a liquid crystal panel to display the image as a dynamic animation, and the contact operation of the contact portion 3 may be controlled by a computer or controller to synchronize with the movement of the animation through motor drive control.

[0030] In the above description, when the external dimensions or sizes are described as "same," "equal," or "different," these descriptions are not in their strict sense. In other words, "same," "equal," and "different" mean "substantially the same," "substantially equal," or "substantially different," allowing for design and manufacturing tolerances and errors.

[0031] In addition to the above, the methods according to the above embodiments and modifications may be used in appropriate combination.

[0032] Although not specifically illustrated, the present invention can be implemented with various modifications within the scope of the invention. [Explanation of symbols]
