  First, the waterproof structure of the indicator with a switch function of this embodiment will be described.

  An indicator for informing the body 2A of the main body 2 of the monitor device 1 of the present embodiment provided with the display unit 11 and the operation switches 13 for informing the biological information such as the heart rate and blood pressure of the patient and the operating state of the device. 50 is exposed outside. When the indicator 50 emits light, an alarm sound is also emitted at the same time. The indicator 50 notifies the patient's condition and the operating state of the device by changing the color, sound quality, volume, lighting, blinking, blinking interval, and the like of the light. The indicator 50 is added with a switch function for temporarily stopping only the alarm sound while the light emission is continued. It should be noted that the time for which the alarm sound is paused can be arbitrarily set by the user.

  The indicator 50 includes, for example, a circuit board 53 on which electrical components such as a switch unit 51 and a light emitting unit 52 are mounted, an operation key 54 that operates the switch unit 51 to an on position or an off position, an operation key 54, and a circuit board 53. And an elastic member 55 for waterproofing, and a fixing member 56 for fixing the elastic member 55 to the mounting portion 24 of the main body 2. It is attached to the provided concave mounting portion 24. The switch unit 51 is, for example, a push-type switch that is displaced in the vertical direction, and the light emitting unit 52 is, for example, an LED element. Two light emitting units 52 are provided on the circuit board 53 so as to sandwich the switch unit 51 in order to make the brightness during light emission uniform.

  The operation key 54 is configured not only to move in the vertical direction but also to transmit to the switch unit 51 a pushing operation from at least three surface directions (a flat surface portion 54b and two side surface portions 54c described later) such as a horizontal direction and an oblique direction. ing. The operation key 54 is made of, for example, a resin material such as translucent polycarbonate that can transmit light from the light emitting unit 52. The elastic member 55 is made of, for example, translucent silicon rubber that can transmit light from the light emitting portion. Further, the fixing member 56 is made of a metal plate having a rust prevention property such as stainless steel formed in a hollow rectangular shape so as to surround the elastic member 55.

  The operation key 54 has a flat surface portion 54b, a plurality of side surface portions 54c and a curved surface portion 54d adjacent to the flat surface portion 54b, and the flat surface portion 54b is configured to be substantially flush with the upper surface portion of the main body portion 2. 54c and the curved surface portion 54d are inclined obliquely downward, and the side surface portion 54c and the curved surface portion 54d are formed from the side wall portion of the main body portion 2 toward the upper surface portion so as to form a part of the side wall portion of the main body portion 2. It has a continuous tapered inclined surface. As a result, the liquid easily flows from the flat surface portion 54b of the operation key 54 along the side surface portion 54c and the curved surface portion 54d, so that the liquid flows from the outer edge 24b of the mounting portion 24 to the side surface portion 54c and the curved surface portion 54d of the operation key 54. It becomes a structure that does not easily enter the gap with the lower edge of the.

  The elastic member 55 is inserted with a flat surface portion 55 a attached to the back surface (opposite side of the operation surface) of the operation key 54 and a cylindrical switch operation portion 54 a extending downward from near the center of the back surface of the operation key 54. A sheath-shaped switch contact portion 55b and a flange portion 55c having substantially the same outer shape as the operation key 54 are provided. The thickness of the flat surface portion 55a is larger than that of the switch contact portion 55b and the flange portion 55c. The lower end portion of the switch contact portion 55b is in contact with the switch portion 51, and has a length such that the switch portion 51 is turned on when the switch operation portion 54a is displaced downward. The flange portion 55c extends downward from the back surface of the flat portion 55a, and is expanded laterally so as to have an outer shape substantially the same as the outer shape of the operation key 54. The flange portion 55 c is fixed with screws 25 or the like in a sealed state in close contact with the stepped portion 24 a of the mounting portion 24 by the fixing member 56. This prevents liquid from entering the circuit board 53 disposed below the stepped portion 24a of the mounting portion 24.

  Further, the attachment portion 24 is formed with a communication hole 26 communicating from the inside to the outside, and the liquid that has reached the flange portion 55c of the elastic member 55 through a gap such as a side wall portion around the operation key 54 and the attachment portion 24 The flange portion 55c is configured to be discharged to the outside through the communication hole 26.

  The elastic member 55 has a shape in which a skirt-like connecting portion 55d extending from the back surface of the flat surface portion 55a to the flange portion 55c is inclined in the diameter increasing direction, and the elastic force between the connecting portion 55d and the switch contact portion 55b. Due to the restoring force of the switch unit 51, the operation key 54 is constantly urged to the side opposite to the switch unit 51 (upward in the figure). As a result, when the operation key 54 is pushed toward the lower switch portion 51 in the figure, the operation key 54 can be displaced toward the switch portion 51 against the elastic force of the elastic member 55, and an external force for pushing the operation key 54 acts. If it stops, it will be pushed up to the opposite side to the switch part 51 by the said elastic force of the elastic member 55, and will return to the original state.

  As described above, according to the present embodiment, in the indicator with a switch function, even if the operation surface and the movable range of the operation key 54 are widened, the waterproof performance is not deteriorated. It is possible to realize a structure that can reliably discharge before reaching the circuit board 53 on which an electrical component such as the light emitting unit 52 is mounted.

  Next, the support structure of the indicator with a switch function of this embodiment will be described.

  The operation key 54 is provided with a protruding portion 54e that protrudes outward from the outer shape of the operation key 54 at a corner diagonally opposite the curved surface portion 54d. The protrusion 54e extends from the lower end of the operation key 54 and has a U-shaped outer shape having a predetermined width and thickness. The operation key 54 is cantilevered by the mounting portion 24 by inserting the protruding portion 54 e into the slit hole 24 b formed in the corresponding portion of the mounting portion 24 with a predetermined gap. The corner where the protrusion 54e is provided may have a curved shape.

  As a result, the operation key 54 swings around the protruding portion 54e as a fulcrum, regardless of which of the flat surface portion 54b, the side surface portion 54c, and the curved surface portion 54d is pressed. It can be reliably transmitted to the switch unit 51. Further, unlike the prior art, there is no need to dispose a structure such as a shaft within the light emission range of the indicator. Therefore, the moving direction of the operation key 54 is not limited, and the light emission range of the indicator is narrowed or light emission unevenness occurs. Nothing will happen.

  The indicator with a switch function of the present invention is not limited to medical devices such as the biological information monitor of the above-described embodiment, and can be applied to various other devices.
