Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lighting device which is used by being attached to the head side or wall side of a hospital bed.

[0002]

[Prior art]

 For example, as a lighting device in a hospital or the like, a lighting device for reading a patient, for example, is known in addition to a room light embedded in a ceiling surface. As such lighting fixtures, those in which a spotlight is directly attached to a wall or the like in such a manner that the headlight can be swung to a certain angle, and a flexible light bent in a letter shape are known. If lighting equipment is used, reading can be performed without interrupting sleep of patients in the same room even at night.

[0003]

[Problems to be solved by the invention]

 In such a lighting device, the former device restricts the light projection area to some extent and narrows the irradiation area of the light to be projected. However, for example, when performing night-time nursing care, the treatment is performed in a dim light where the illumination light does not reach the desired affected part well, or the room light is turned on and another patient sleeping in the same room is sleeping. I have to obstruct and take measures.

In the latter case, the light source can be moved to a desired place. However, since the light emitted from the light source is not sufficiently stopped, the affected part is illuminated with the diffused light. Therefore, there is also a possibility that the brightness required for the work cannot be obtained (there is a possibility of obstructing the treatment).

[0005] In view of the above-mentioned circumstances, the present invention provides a simple switching operation so that when a patient or the like uses the device, it does not spread and burden the patient's eyes. The purpose is to provide lighting equipment that can locally illuminate and project light to the affected area when performing the act.

[0006]

[Means for Solving the Problems]

 That is, the invention of claim 1 is to attach a light source provided on the head side or a wall side of a bed used by a patient or the like in a hospital or a clinic via a bendable and rotatable arm. An illuminating device for illuminating a desired portion by moving to a position, comprising: a base rotatably provided at the tip of the arm; a light source immovably provided on the base; and light emitted from the light source. A hood which is rotatable with respect to the base having a light emitting surface provided with a fine uneven surface to be frosted glass on the lower surface side and a transparent surface provided on a part of the light emitting surface; A handle to be gripped by a medical practitioner, and when used by a patient, when the patient is rotated near the patient, the uneven surface is positioned on the emission optical path of the light source and is illuminated with diffused light, and care assistance is provided. When the person operates, When rotated, the transparent surface is positioned on the emission optical path of the light source, and spot-shaped emission light is projected onto the affected part.

[0007]

[Embodiment of the invention]

 Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a lighting device according to the present invention. The lighting device is provided with an arm on a wall (a head side of a bed, for example, a headboard or a floor stand, etc.) W of a hospital room (of a hospital or a clinic). A base 3 is attached to the tip of the arm 1 via a swing mechanism 2 that can freely move in a direction orthogonal to XYZ. The base 3 has a light source 4 fixed thereto and a cover 5 rotatably attached thereto.

The arm 1 is formed in a substantially elliptical shape, and is bent downward from an intermediate portion so that the light projecting position can be freely moved forward, backward, left and right. The arm 1 has substantially cylindrical joints at three positions, a base, an intermediate part and a distal end, each of which can be rotated in the vertical direction. The swing mechanism 2 is attached. An appropriate mounting portion 8 is provided at the base end of the arm 1, and the arm 1 is mounted on the wall surface W of the hospital room with the mounting portion 8.

As shown in FIG. 2, the swing mechanism 2 is provided between three ends (not shown) provided in the X, Y, and Z directions between the tip of the arm 1 and the base of the base 3. Thus, the light source 4 can rotate freely in the three-dimensional direction with respect to the arm 1. Reference numeral 22 indicates a fixed knob.

The base 3 shown in FIG. 3 is configured so that a cover 5 is sandwiched by a sandwiching plate 34 described later provided at the tip, and a heat shield plate 31 is fixed to the tip. Further, a socket 32 is fixedly provided at an arbitrary position other than the center of the heat shield plate 31.

The cover 5 has a substantially trumpet (cylindrical) shape whose tip end is widened, and in this embodiment, it is 180 degrees with respect to the outer peripheral surface of the base 3 (in the present invention, the angle is not limited to this angle, but is arbitrary). (Applicable range is applicable).

As shown in FIG. 3, a tempered glass plate (frosted glass constituting the diffusion portion) 51 which is subjected to a diffusion process by fine unevenness processing and is just fitted into the opening portion is fixed to the opening of the cover 5 as shown in FIG. Further, at a position deviated from the center of the tempered glass plate 51, as shown in FIG. 4, there is provided a transparent portion 51A in which only a part is not subjected to the diffusion processing. The transparent portion 51A transmits light controlled by the reflecting mirror 33, and irradiates a diseased part or the like with light (spot light) locally having a narrow-angle light distribution. A louver 52 formed in a substantially lattice shape is provided outside the tempered glass plate 51. A hood 54 cut diagonally is attached to the open end of the cover 5.

Furthermore, a part of the outer peripheral surface of the cover 5 has a substantially U-shape, and a patient and a medical practitioner such as a doctor or a nurse can freely grip and change the rotational position of the cover 5. A cutting handle 6 is provided. In addition, the movement of the cover 5 by the handle 6 allows the light projection state of the light source to be switched between two types (a state in which the light from the light source is diffused and a state in which the light is narrowed down). I have. A power switch S for turning the power on and off is provided on the cover 5 near the mounting portion of the handle 6. The base 3 is provided with a dimming switch (not shown) for adjusting the illuminance of the light from the light source 4 in two stages, but this is not particularly necessary.

Therefore, according to this embodiment, as shown in FIG. 5, for example, when the patient P raises his / her upper body from a bed and reads a newspaper or a book, his arm is extended and one hand is used. Then, the handle 6 is grasped, the arm 1 is operated, the cover 5 is pulled, and the power switch S 1 is turned on. As a result, as shown in FIG. 6, the light from the light source 4 enters the ground glass portion of the tempered glass plate 51 immediately below, so that the soft diffused light L1 can illuminate the patient's hand or the like brightly.

On the other hand, when the caregiver A or the nurse performs an appropriate operation, for example, observes the affected part or changes a bandage, as shown in FIG. Is extended, the handle 1 is grasped, the arm 1 is operated, and the cover 5 is pulled to the side to rotate the handle 6 by about 180 degrees. As a result, as shown in FIG. 8, since the transparent portion 51A of the tempered glass is located immediately below the light source 4, it is possible to directly project the bright spot-shaped light L2 from the light source to a desired site of the patient. it can.

[0016]

[Effect of the invention]

 As described above, according to the present invention, the base provided rotatably at the tip of the arm, the light source provided immovably on the base, and the ground glass on the lower surface side from which the light from the light source exits. A cover that is rotatable with respect to a base having a light emitting surface provided with a fine uneven surface and a transparent surface provided on a part of the light emitting surface, and a handle that is integrally attached to the cover and is gripped by a patient and a caregiver. When used by a patient, when turned to the patient's hand, the uneven surface is located on the emission optical path of the light source, and when operated by a caregiver, the transparent surface is turned to the hand. Since it is located on the light path of the light source and emits light to the affected part, the irradiation state can be switched by a very simple operation such as turning the handle near the hand.

Therefore, according to the present invention, when a patient or the like uses the object for reading or the like, the diffused light is made incident to process the light into a soft light that does not burden the patient's eyes. When assisting, bright and local spot illumination / light projection to the affected area is possible.
