<Embodiment 1>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the appearance configuration of the grip type switch 1 will be described.

Hereinafter, the appearance configuration of the grip type switch 1 will be described with reference to FIGS. 1 to 4. 1 to 4 are external views showing the appearance of the grip type switch 1. In FIGS. 1 to 4, the state facing the button 12 is the front. FIG. 1 is a front view when the button 12 of the grip type switch 1 is arranged in the front. FIG. 2 is a side view of the grip type switch 1 (a view when the button 12 is arranged at the right end). FIG. 3 is a top view of the grip type switch 1. FIG. 4 is a back view of the grip type switch 1. In the description of each figure, the left-right direction facing the button 12 is the X-axis direction, the vertical direction is the Y-axis direction, and the depth direction is the Z-axis direction.

The grip type switch 1 has a configuration in which a button 12 is provided on the housing 11 (FIGS. 1 and 2). The housing 11 has an elongated shape with the Y-axis direction as the longitudinal direction (FIG. 1). The bush 14 and the cord 15 extend from one end side (−Y side) of the elongated shape of the housing 11 (FIG. 1). A button 12 is arranged on the other end side (+ Y side) of the elongated shape of the housing (FIG. 1).

The cord 15 connects to any medical device (not shown). The bush 14 is a member used for cushioning the connection portion between the cord 15 and the housing 11, and is made of, for example, nylon, Teflon, soft vinyl chloride, or the like.

The grip type switch 1 has a size that can be gripped with one hand, and the detailed size will be described later with reference to FIG.

Referring to FIG. 2, the housing 11 has an elongated shape in the Y-axis direction and has a curved surface 111 gently curved from the longitudinal direction (Y-axis direction) to the lateral direction (Z direction). In other words, the housing 11 has an elongated shape and is gently curved in the + Z direction. The button 12 is a button provided on the tip surface of the housing 11 in the bending direction (intermediate direction between the + Y direction and the + Z direction). The button 12 is a button that is pushed by the user, and the pushing surface 121 (surface) thereof is an arc as shown in the figure. In other words, the button 12 has a dome-shaped shape. The push-in surface 121 of the button 12 is preferably sized larger than the user's thumb, and has, for example, a major axis of 10 to 30 mm. With such a large size, it is possible to easily push the button 12 with any finger. Further, even when the user's hand is small, the button 12 can be easily pressed.

The light emitting unit 13 is provided in parallel with the boundary surface 112 of the button 12 and the housing 11 (FIG. 2), and is a ring-shaped indicator (FIGS. 1 and 3). When the button 12 is pressed by the user, the light emitting unit 13 emits light so as to notify the pressing. By emitting light from the light emitting unit 13, various notifications can be given to the user. For example, when the light emitting unit 13 emits light, it is possible to inform the user when to press the button 12 when using the light emitting unit 13 for training purposes.

The position of the light emitting unit 13 on the housing 11 may be any position, and may not be a ring shape. That is, the light emitting unit 13 may be any visual notification means capable of notifying the pressing of the button 12.

As is clear from FIG. 3, the buttons 12 are arranged so as to be convex in the + Z direction (the front direction when the button 12 is viewed from the front).

When the grip type switch 1 is viewed from the back surface (the back surface when the button 12 is viewed from the front) (FIG. 4), it has an elongated shape in the vertical direction (Y-axis direction).

Referring to FIGS. 1 to 4, the gripping switch 1 has a rounded silhouette with no corners as a whole. This makes it easier for the gripping switch 1 to fit in the subject's hand when gripped by the subject.

The shape and size of the grip type switch 1 will be further described with reference to FIG. FIG. 5 is a view similar to the side view of FIG. 2 with appropriate description added. The grip type switch 1 has an elongated shape as shown in the figure, and the length A in the longitudinal direction L1 is 60 to 100 mm. The curved surface 111 of the grip type switch 1 is gently curved from the longitudinal direction L1 toward the lateral direction (Z direction) (in other words, is curved toward the + Z direction). The button 12 is arranged at a position deviated from the longitudinal direction L1 on the side surface side (+ Z direction).

The button 12 is provided on the tip surface of the housing 11 in the bending direction, and the pushing surface 121 is an arc. Here, the midpoint of the arc of the button 12 is T1, and the tangent of the arc passing through the midpoint T1 is L2. Let P1 be the perpendicular line P1 of the tangent line L2 passing through the midpoint T1, and let M1 be the intersection of the perpendicular line P1 and the longitudinal direction L1. Further, the end point of the housing 11 in the longitudinal direction L1 is set to E1. In this case, the length B from the end point E1 to the intersection M1 is 20 to 50 mm.

The angle C formed by the perpendicular line P1 and the longitudinal direction L1 is 40 to 90 degrees (preferably 50 to 75 degrees). Further, the maximum width D of the housing 11 in the lateral direction (vertical direction of the longitudinal direction L1) is about 40 to 70 mm, and the maximum width E of the handle portion (up to the point where the bending angle changes) is about 30 to 60 mm. Further, the maximum length F of the housing 11 in FIG. 3 in the X-axis direction (depth direction) is 30 to 50 mm.

As described above, the length A of the longitudinal direction L1 is an elongated shape of 60 to 100 mm, and the button 12 is arranged at a position curved at an angle C (40 to 90 degrees) along the longitudinal direction L1. The width of the Japanese hand (the straight line distance from the radial middle hand point to the ulnar middle hand point) is 95.1 mm or less for men at the maximum (Non-Patent Document 1). Therefore, the length A is 60 to 100 mm, the maximum width E of the handle portion is about 30 to 60 mm, and the maximum width D in the lateral direction is about 40 to 70 mm. Further, the maximum length F of the housing 11 in the X-axis direction in FIG. 3 is 30 to 50 mm. Since the length of the Japanese hand (from the tip of the stalk) is approximately 166 mm to 210 mm (Non-Patent Document 1), the housing 11 is attached with three or four fingers (see FIGS. 7 and 8 described later). You can grip it by wrapping it tightly.

The structure of the human hand will be briefly described with reference to FIG. When the index finger is closed and the thumb is extended without exerting force, the angle between the index finger and the thumb is about 40 to 90 degrees (angle G in FIG. 6A). When the middle finger / ring finger / little finger is closed and the index finger is extended without force, the angle between the middle finger and the index finger is about 0 to 50 degrees (angle H in FIG. 6B). Therefore, since the button 12 is curved at an angle of 40 to 90 degrees along the longitudinal direction L1, even when the button 12 is pressed with the thumb (FIG. 7 described later), the button 12 is pressed with the index finger. Even so (FIG. 8 to be described later), it is possible to perform a reasonable grip and button operation according to the movable range of the joint. The details will be described with reference to FIGS. 7 and 8.

A first example of the usage state of the grip type switch 1 will be described with reference to FIG. 7. In the first example, a usage state in which the button 12 is pressed with the thumb f1 is shown. When four fingers (thumb, middle finger, ring finger, and little finger) are wound in the lateral direction of the housing 11 (direction orthogonal to the longitudinal direction L1), the extension direction L3 of the thumb f1 is substantially parallel to the longitudinal direction L1. Then, when the thumb f1 is extended, it is extended toward the button 12. That is, the difference between the above-mentioned angle C and the angle G (the angle formed by the thumb f1 and the index finger) is small. This is because the angle between the index finger and the thumb is about 40 to 90 degrees when the index finger is closed and the thumb is extended without exerting force (angle G in FIG. 6A). Then, by slightly bending the first joint of the thumb f1, the button 12 is naturally arranged near the abdomen of the thumb f1. That is, the belly of the thumb f1 can be arranged in substantially the same direction as the tangent line L2. Further, since the length A (FIG. 5) in the longitudinal direction L has the above-mentioned size, the four fingers can be arranged so as to be wrapped around the housing 11 without difficulty. That is, the housing 11 can be firmly gripped, and the thumb f1 can be naturally placed on the button 12.

Further, a second example of the usage state of the grip type switch 1 will be described with reference to FIG. The second example shows a usage state in which the button 12 is pressed with the index finger f2. When the three fingers (middle finger, ring finger, and little finger) are wrapped around the housing 11 in the lateral direction (direction orthogonal to the longitudinal direction L1) and gripped, the extension direction L4 of the middle finger is relative to the longitudinal direction L1. Almost orthogonal. Therefore, the direction of the perpendicular line P1 (that is, C formed by the longitudinal direction L1 and the perpendicular line P1) substantially coincides with the direction when the index finger f2 is extended. This is because the angle C between the longitudinal direction L1 and the vertical line P1 is 40 to 90 degrees, and the angle between the middle finger and the index finger when the middle finger / ring finger / little finger is closed and the index finger is extended without force is 0 to 50. This is because it is about a degree (angle H in FIG. 6B). Further, since the length A (FIG. 5) in the longitudinal direction L has the above-mentioned size, the three fingers can be arranged so as to be wrapped around the housing 11 without difficulty. Therefore, the user can firmly grip the housing 11 and can comfortably place the pad of the index finger f2 on the button 12. As a result, the operator can operate the button 12 while grasping the grip type switch 1 without discomfort.

In FIG. 8, the button 12 is pressed with the index finger f2, but of course, the button 12 may be pressed with the middle finger. Further, as shown in FIG. 3, the grip type switch 1 has a symmetrical structure. Therefore, the user can grip the grip type switch 1 without discomfort regardless of whether the user holds it with his right hand or with his left hand. Further, if the angle C is 50 to 75 degrees, the gripping type switch 1 can be gripped more naturally without exerting more force on each joint.

Subsequently, the effect of the grip type switch 1 having the appearance configuration shown in FIGS. 1 to 8 will be described. As shown in FIGS. 7 and 8, the user grips the lower side of the housing 11 (the stretched side of the cord 15) by wrapping it with three or four fingers. Here, since the length of the housing 11 in the longitudinal direction is 60 to 100 mm, three or four fingers can be firmly wrapped around it. Further, the angle formed by the longitudinal direction L1 and the perpendicular line P1 is 40 to 90 degrees. Due to this angle, when the button 12 is pressed with the index finger f2, when three fingers (middle finger, ring finger, little finger) are wound around the housing 11, the button 12 is arranged in the natural extending direction of the index finger f2. .. Further, due to the angle, when the button 12 is pressed with the thumb f1, when the four fingers (index finger, middle finger, ring finger, little finger) are wrapped around the housing, the button 12 is arranged at the natural position where the thumb f1 is spread. Will be done.

As described above, since the grip type switch 1 has the shape and size shown in FIG. 5, it can be firmly gripped and can be operated reasonably. Further, the shape allows the button 12 to be operated with a finger according to the user's preference.

Further, the length B of the intersection M1 of the perpendicular line P1 and the longitudinal direction L1 and the end point E1 of the housing 11 on the button 12 side in the longitudinal direction L1 is 20 to 50 mm. With this size, the size of the housing 11 does not become too large, and the thumb f1 and the index finger f2 can be naturally arranged on the button 12 as described above.

The housing 11 has a rounded shape with no corners. This allows the user to grip the housing 11 firmly.

Subsequently, the internal structure in the vicinity of the button 12 will be described with reference to FIG. FIG. 9 is a cross-sectional view taken along the line AA in FIG. 2 (that is, an enlarged cross-sectional view of the button 12). As shown in the figure, the button 12 has a curved pushing surface 121, which is a surface pressed by a user's finger (a surface exposed to the outside). More specifically, the button 12 has an arc on the pushing surface 121 (in other words, it has a dome shape). In the example of FIG. 9, the pushing surface 121 of the button 12 has an elliptical arc, but the present invention is not limited to this and may be an arc.

The button 12 has a contact point 17 with the detection member 16 on the perpendicular line P1 of the tangent line L2 of the midpoint T1 of the arc of the push-in surface 121. The contact point 17 is a point at which the push of the button 12 is conducted. As a result, no matter where the force is applied to the pushing surface 121 of the button 12, the force is transmitted toward the contact point 17 existing in the center direction of the arc. That is, the force applied to the pushing surface 121 of the button 12 is transmitted so as to be concentrated at the contact point 17 existing in the center direction of the arc.

The relationship between the button 12 and the detection member 16 will be further described from different viewpoints. The detection member 16 is provided inside the housing 11 and in the direction inside the button 12. Further, the arbitrary pushing surface 121 of the button 12 moves toward the substantially center point of the arc when pushed. In other words, the button 12 moves closer to the contact point 17 no matter which location is pressed. Whenever a force is applied to the button 12, the force is transmitted toward the contact point 17, so that the push of the button 12 can be detected accurately.

The guide 113, which is a part of the housing 11, supports the button 12 so as to limit the moving direction of the button 12 only in the direction of the perpendicular line P1 (only in one direction) when the button 12 is pushed. In other words, since the guide 113 is fixed so as to surround the button 12 from both sides of the vertical line P1 in the vertical line direction, the movement direction of the button 12 is limited to one direction. As a result, the force is efficiently and stably transmitted to the contact point 17 regardless of which part of the pushing surface 121 of the button 12 is pressed.

The detection member 16 is a member for detecting the pressing of the button 12, and an example thereof includes a tact switch. The force from the button 12 is transmitted to the contact point 17. The vicinity of the contact point 17 of the detection member 16 constitutes a so-called electrical contact.

The detection member 16 detects a force transmitted to the contact point 17, and energizes the internal electric circuit by this force. The detection member 16 notifies the external device of the detection signal generated by the energization via wiring (not shown) or wiring in the cord 15. The detection member 16 stops the output of the detection signal when the detection of the force with respect to the contact point 17 is completed.

Further, the detection member 16 may input a detection signal to the light emitting unit 13 when a force is applied to the contact point 17. The light emitting unit 13 has, for example, an indicator lamp (one aspect of a light emitting element) and a peripheral circuit thereof. The light emitting unit 13 emits light when a detection signal is input. That is, the light emitting unit 13 emits light while the button 12 is being pushed.

The detection member 16 has a semicircular spherical convex portion 161 that tapers toward the contact point 17. As a result, the detection member 16 detects the force transmitted from the button 12 at one point (narrow area) instead of the surface. Since the detection member 16 detects the force at one point, it is possible to accurately detect the pressing of the button 12 even if the force applied to the button 12 is weak.

The convex portion 161 of the detection member 16 is not limited to a semicircular spherical shape, and may have another convex shape (for example, a triangular prism shape such as a triangular prism or a square prism having a tapered shape). That is, the detection member 16 may have another form as long as it comes into contact with the button 12 so as to support the point when the button 12 is pushed.

FIG. 10 is a first modification of the cross section of the button 12 of the grip type switch 1. As shown in the figure, a semicircular spherical convex portion 122 is provided on the button 12 side. In this configuration, the force applied to the arbitrary pushing surface 121 of the button 12 is concentrated on the convex portion 122 and transmitted to the detection member 16. Since the detection member 16 detects the force at one point (contact point 17), it is possible to accurately detect the pressing of the button 12 even if the force applied to the button 12 is weak.

Even in this configuration, the guide 113 limits the moving direction when the button 12 is pushed to only the vertical line P1 direction. As a result, the applied force is easily transmitted to the contact point 17 regardless of which part of the pushing surface 121 is pushed.

That is, to outline FIGS. 9 and 10, it is preferable that at least one of the detection member 16 and the button 12 has a convex portion (122, 161) that is convex toward the contact point 17 with the other. Here, the convex shape portion (122, 161) does not necessarily have to be a hemispherical shape, and may be a shape that is convex toward the other side (for example, a tapered shape). As a result, even if the force applied to the button 12 is weak, it is possible to accurately detect the pressing of the button 12.

FIG. 11 is a second modification of the cross section of the button 12 of the grip type switch 1. The basic configuration is the same as in FIG. 9, but the material configuration of the detection member 16 is slightly different. In this modification, the convex portion 161 of the detection member 16 is made of an elastic material (for example, an elastic material such as rubber) that is softer than the material of the surface (pushing surface 121) of the button 12. A base 162 that constitutes an electrical contact is provided at the end of the convex portion 161 in the wide direction.

With this configuration, the force applied by pressing the button 12 is buffered by the convex portion 161 and then transmitted to the base 162. Since the force is buffered and transmitted, the durability of the detection member 16 (particularly the electrical contact) can be improved. In other words, the risk of failure etc. is reduced even if it is used for a long period of time.

Also in the configuration of FIG. 10, the convex portion 122 may be made of an elastic material (for example, an elastic material such as rubber) that is softer than the material of the surface (pushing surface 121) of the button 12. As a result, the force applied when the button 12 is pressed is buffered and transmitted, and the durability of the detection member 16 (particularly the electrical contact) can be improved.

In the above description, the detection member 16 is described as supporting the button 12 (or the button 12 supports the detection member 16) (FIGS. 9, 10, and 11). Here, the point support means that the tip portion of the tapered shape (the shape that tapers toward the contact point 17) supports the contact point 17, and the contact point 17 may have a certain area. Further, although point support is expected to improve the detection sensitivity, the point support configuration is not an essential configuration.

Subsequently, an example of using the grip type switch 1 will be described with reference to FIG. FIG. 12 is an external view showing a perception test device 100 including the grip type switch 1 as a part of the configuration. The perception test device 100 has a grip type switch 1 and a perception test unit 2. The perception test unit 2 can be connected to the electrode 3 via the cable 4.

The electrode 3 is attached to the skin surface of the subject (for example, the instep). The sensory test unit 2 stimulates peripheral nerve fibers (Aδ fibers, C fibers) via the electrodes 3. The perception test unit 2 has a display and an interface for setting a current (for example, a button or a wheel scroll) on the housing. The examiner adjusts the stimulus given to the subject through the electrode 3 by manipulating this interface.

The subject holds the grip-type switch 1 while the electrode 3 is attached. The subject presses the button 12 of the gripping switch 1 when he / she feels a stimulus through the electrode 3. When the button 12 is pressed, the detection signal is input to the perception test unit 2. The sensory test unit 2 measures the time from the start of stimulation to the pressing of the button 12. The subject's peripheral nerves are evaluated according to the measurement time and the intensity of the stimulus current.

The detailed configuration of the perception test unit 2 may be, for example, the same configuration as that of the cited document 3. Further, the detailed configuration of the electrode 3 may be, for example, the same configuration as that of the cited document 4.

The perception test device 100 is an example of a medical device having the grip type switch 1 as a part of the configuration. The grip type switch 1 may be applied to other medical devices (for example, an electroencephalogram measuring device or a hearing test device). That is, the above-mentioned perceptual test unit 2 is an aspect of a medical unit that receives a signal from the grip type switch 1 and performs an arbitrary test or treatment.

Further, the grip type switch 1 may be used for a nurse call to communicate with a nurse station in a hospital. That is, the grip type switch 1 may be used for the patient to call the nurse from the vicinity of the bed in the ward. As described above, the grip type switch 1 can be used in any situation in the medical field to convey the intention of the subject or the patient.

Although the invention made by the present inventor has been specifically described above based on the embodiments, the present invention is not limited to the embodiments already described, and various changes can be made without departing from the gist thereof. It goes without saying that it is possible.

For example, a simple gripping switch 1 that does not have a light emitting unit 13 may be used. Even with this configuration, the grip type switch 1 is easy to grip and can accurately detect the pressing of the button 12.
