Description

  The present invention relates to a medical headlight, and more particularly to a medical headlight used when a medical worker performs a medical action such as surgery.

  In general, a surgical light is installed in the operating room as a device for illuminating the surgical field. In addition, when detailed work is required, it is common to use a medical headlight that is attached to the head of an operator (operator or doctor) and partially illuminates the surgical field (for example, , See Patent Document 1).

JP 9-51900 A

  Conventional medical headlights are assumed to be used in an auxiliary manner together with the surgical light, and are not supposed to be used outside the hospital. For example, when a doctor uses a conventional medical headlight to perform medical activities such as surgery in places where there is no surgical light, such as in evacuation shelters and in emergency vehicles, the illuminance is inadequate. It was sufficient and unevenness of light distribution was present.

  An object of the present invention is to provide a medical headlight that can realize a lighting environment sufficient for a doctor to perform a medical action even in an environment where a surgical light is not installed. And

The medical headlight according to the present invention is
A headband having a curved shape configured to be mounted on the operator's head;
In a state of being located outside the headband, it is connected to a fixing portion provided in at least two locations of the headband, and includes a main body portion on which an LED element is mounted,
The main body has a plurality of light emitting surfaces on which the LED elements are mounted,
The plurality of light emitting surfaces are arranged such that the optical axes of light beams emitted from the plurality of light emitting surfaces intersect at substantially the same location.

  According to said structure, since it arrange | positions so that the optical axis of the light beam inject | emitted from each light emission surface may cross | intersect at substantially the same location, it is very high in the area | region containing the location where the said optical axis cross | intersects Illuminance is achieved.

  When an operator performs a medical practice, the distance between his / her head and the patient's operative field is within a certain range. That is, when the operator wears the headband on his / her head and uses the medical headlight, the distance between the LED element mounted on the main body and the illumination area is within a substantially constant range. . For example, this distance is in the range of 400 mm to 800 mm. Therefore, by adjusting the position or angle of the light emitting surface so that the optical axes of the light beams emitted from the respective light emitting surfaces intersect at a position ahead of the distance from the light emitting surface, there is no operating light. Illuminance sufficient to perform medical practice can be realized even below.

  It should be noted that the optical axes of the light beams emitted from a plurality of light emitting surfaces “intersect at substantially the same location” means that the optical axes of the respective light beams completely intersect at the same point, This is a concept including a case where optical axes of a plurality of light beams intersect in a region. The “neighboring region” here refers to a region shifted by a distance of 10% or less with respect to the width of the irradiation region of the light flux at the position.

  The two or more light emitting surfaces may be arranged on different circumferences centering on a position where the optical axes intersect each other.

In the medical headlight,
The plurality of light emitting surfaces are arranged in a predetermined direction along the shape of the main body,
Among the plurality of light emitting surfaces, the light emitting surface arranged at the end with respect to the predetermined direction has a distance from the position where the optical axes intersect with each other, rather than the light emitting surface arranged at the center with respect to the predetermined direction. It doesn't matter if it is far away.

  With this configuration, each light emitting surface is arranged in a shape that matches the shape of the operator's head. For this reason, even if an operator performs a medical practice in a state where the medical headlight is mounted, the headlight is prevented from obstructing the medical practice.

The plurality of light emitting surfaces include a first LED element having a first color temperature and a second LED element having a second color temperature.
The first LED element and the second LED element may be individually configured to be able to adjust the supply current amount.

  By adopting such a configuration, light with different color temperatures is irradiated onto the same region, so that color unevenness in the irradiation region is suppressed. In addition, under such a configuration, the color temperature in the irradiation region can be adjusted while suppressing color unevenness by individually adjusting the supply current amount for the first LED element and the second LED element.

The main body has a plurality of flat surfaces formed in steps,
Each of the plurality of light emitting surfaces may be formed on the plurality of flat surfaces.

At this time, the main body has a flexible substrate,
The plurality of flat surfaces may be formed by bending the flexible substrate a plurality of times.

The medical headlight is
A hinge part capable of adjusting a coupling state of the main body part and the headband;
The main body may be configured to be rotatable in the vertical direction with respect to the headband.

The main body includes a fin on a surface opposite to the light emitting surface,
In a state where the headband is mounted on the head of the operator, the fins may be arranged at positions spaced from the headband.

  As another configuration, the main body portion may be provided with fins on the surface of the flexible substrate opposite to the side on which the LED element is mounted.

  The medical headlight is configured so that sufficient illuminance can be achieved even in the absence of a surgical light. For this reason, it is assumed that a high-luminance element is used as the LED element provided on the light-emitting surface. However, the light-emitting surface is assumed to become high temperature during light emission. According to the above configuration, since the fin is provided at a position separated from the head, it is possible to avoid a situation in which the face and the head become hot when the operator is wearing the medical headlight and performing a medical practice. .

  In the medical headlight, the areas of the irradiation regions of the light beams emitted from the two or more light emitting surfaces may be different from each other at a position where the optical axes intersect. More specifically, the divergence angles of light beams emitted from two or more light emitting surfaces may be made different. The method of varying the divergence angle can be realized, for example, by providing an optical member together with the LED element on the light emitting surface and appropriately adjusting the design of the optical member.

  According to the medical headlight of the present invention, it is possible to realize a lighting environment sufficient for a doctor to perform a medical practice even in an environment where no surgical light is installed.

  An embodiment of a medical headlight according to the present invention will be described with reference to the drawings. The following drawings merely show an embodiment of a medical headlight, and are not intended to limit the present invention to the illustrated structure. Moreover, in each figure, the dimension ratio of drawing and an actual dimension ratio do not necessarily correspond.

  FIG. 1 is a perspective view schematically showing one embodiment of a medical headlight. FIG. 2 is a perspective view schematically showing an enlarged part of FIG. The medical headlight 1 includes a headband 3, a main body 5, and a control box 10. A plurality of LED elements 7 are mounted on the main body 5. In addition, as shown in FIG. 2, the fin 9 for cooling is provided in the back side of the side in which the LED element 7 is arrange | positioned in the main-body part 5. As shown in FIG.

  In the present embodiment, the main body 5 is mounted with a plurality of LED elements 7 a having a light bulb color (first color temperature) and a plurality of LED elements 7 b having a white color (second color temperature). By adjusting the ratio of the amount of current supplied to the bulb-colored LED element 7a and the amount of current supplied to the white LED element 7b, the color temperature of the emitted color can be adjusted. Yes. In FIG. 1, the bulb-colored LED element 7 a is hatched.

  As shown in FIG. 1, the main body 5 has a curved band shape. A plurality of light emitting surfaces 60 are formed along the shape of the main body portion 5, that is, along the direction d1. Each light emitting surface 60 is composed of a plurality of (here, four) LED elements 7 as described above. Each light emitting surface 60 may be constituted by a single LED element 7.

  The headband 3 has a curved shape so that it can be worn on the operator's head. FIG. 3 is a drawing schematically showing a state where the operator 40 actually wears the medical headlight 1 and performs a medical action on the patient 43 placed on the placement table 41.

  In the present embodiment, the main body portion 5 is fixedly connected to the headband 3 by fixing portions 4 provided at two places. The main body portion 5 is located outside the headband 3 under the state where the main body portion 5 is connected by the fixing portion 4. Further, the main body 5 is provided with an angle adjusting knob 8. By loosening the knob 8, the main body 5 can be rotated in the vertical direction around the head of the operator 40. Thereby, the direction of the light beam 50 (see FIG. 3) emitted from the LED element 7 can be adjusted. The knob 8 in this embodiment corresponds to a “hinge part”.

  The control box 10 is connected to the main body 5 via a cable 23. The control box 10 includes a control unit, which will be described later, and an amount of current determined by the control unit is supplied to the main body unit 5 through the cable 23. By controlling the amount of current sent from the control box 10, the light emission control of the LED element 7 is performed.

  The main body 5 includes a face guard 21. There is a risk that blood or other body fluids may scatter from the patient 43 during the medical practice. The face guard 21 is provided for the purpose of preventing the body fluid from adhering to the face of the operator 40.

  In the present embodiment, each light emitting surface 60 is designed such that the light beams emitted from the light emitting surface 60 intersect at one point. FIG. 4 is a drawing schematically showing the configuration of the main body 5 on which the light emitting surface 60 is formed. In the example illustrated in FIG. 4, an example in which six light emitting surfaces 60 are formed on the main body 5 along the direction d1 is illustrated. And regarding the direction d1, it arrange | positions so that it may approach an edge part from a center part in order of the light emission surface 60a, the light emission surface 60b, and the light emission surface 60c. In FIG. 4, the optical axis of the light beam emitted from each light emitting surface 60 is illustrated by the long broken line. In the present embodiment, a case is described in which three light emitting surfaces 60 are arranged symmetrically in the left-right direction along the direction d1, but this aspect is merely an example. That is, the number of the light emitting surfaces 60 is not limited to 6, and each light emitting surface 60 may be disposed asymmetrically.

  According to FIG. 4, the optical axis 61a of the light beam emitted from the light emitting surface 60a, the optical axis 61b of the light beam emitted from the light emitting surface 60b, and the optical axis 61c of the light beam emitted from the light emitting surface 60c are all minute. Crosses in region 62. That is, by including the position of the minute area 62 in the illumination area 51 (see FIG. 3), the illumination area 51 has extremely high illuminance. In FIG. 4, only the light emitting surface 60 arranged in the left half region in the drawing is discussed, but the same applies to the light emitting surface 60 arranged in the right half region.

  In FIG. 4, among the light emitting surfaces 60, the light emitting surface 60 c disposed near the end with respect to the direction d <b> 1 is farther from the minute region 62 than the light emitting surface 60 a disposed near the center. Placed in position. That is, when viewed from the minute region 62, the light emitting surface 60c is located at a position deeper than the light emitting surface 60a. By setting it as such a structure, it becomes possible to make the shape of the main-body part 5 follow the shape of the head of the operator 40, and it is suppressed that the operator's 40 medical practice is obstructed.

  An example of a specific method configured in this way is realized by arranging each light emitting surface 60 on a minute region 62, more specifically, on the circumference centered at the intersection of each optical axis 61. . In FIG. 4, the light emitting surface 60a is arranged on the circumference c1, centered on one point in the minute region 62, the light emitting surface 60b is arranged on the circumference c2, and the light emitting surface 60c is arranged on the circumference c3. The case is illustrated.

  5A and 5B are drawings schematically showing the structure of the main body 5 in the present embodiment, FIG. 5A corresponds to a perspective view, and FIG. 5B corresponds to a plan view. 5A and 5B are drawings in a state where the light emitting surface 60 including the LED element 7 is not mounted. The main body 5 is configured by being integrally formed with a metal member 70 such as aluminum, magnesium, copper, or copper alloy.

  As shown in FIGS. 5A and 5B, the metal member 70 has a plurality of flat surfaces 71 on one side, and the adjacent flat surfaces 71 are connected to each other by a lateral rib 72. And the main-body part 5 is provided with the fin 9 formed in the opposite side to the flat surface 71. FIG. With such a configuration, it becomes possible to stably mount the light emitting surface 60 including the LED elements 7 on each flat surface 71. Further, since the lateral ribs 72 are formed, the mutual positional relationship between the flat surfaces 71 is stably maintained. Accordingly, even if the operator 40 actually attaches the headlight 1 and rotates the main body 5 in the vertical direction to adjust the traveling direction of each light beam emitted from each light emitting surface 60, The positional relationship between the optical axes 61 of the light beams is maintained. That is, as described above with reference to FIG. 4, the optical axes 61 are maintained in a state of intersecting at almost one point (the minute region 62).

  When forming the light emitting surface 60 on the plurality of flat surfaces 71 as shown in FIGS. 5A and 5B, for example, the flexible substrate on which the plurality of LED elements 7 are mounted is bent a plurality of times to form the flat surfaces 71 and This can be realized by arranging the horizontal ribs 72 along the horizontal ribs 72.

  Returning to FIG. 1, the main body 5 includes a microphone 22. When the operator 40 inputs a predetermined voice through the microphone 22, control based on the voice signal is executed in the control box 10. This control content will be described later.

  The medical headlight 1 includes a battery box 25. A battery (not shown) is built in the battery box 25. The battery box 25 is provided with a charging connector 26. By connecting a cable (not shown) through the connector 26, the built-in battery can be charged from a commercial power source, for example. A battery built in the battery box 25 is electrically connected to the control box 10 via a battery cable 27. Electric components such as a control unit provided in the control box 10 and the LED elements 7 mounted on the main body unit 5 are supplied with electric power from a battery built in the battery box 25. However, the medical headlight 1 does not exclude a configuration in which power is directly supplied to each component from a commercial power supply by connecting a cable to the connector 26.

  The battery box 25 includes a remaining amount display unit 28 for displaying the remaining battery level, and a remaining amount warning speaker 29 for outputting an audio signal to that effect when the battery level falls below a predetermined remaining level. Yes. For example, the remaining amount display unit 28 includes light emitting portions of three colors of red, yellow, and green. When the remaining amount of the battery is 50% or more, the remaining amount display unit 28 emits green light, and when the remaining amount is 20% or more and less than 50%. Is configured to emit yellow light, and to emit red light when less than 20%. The remaining amount display unit 28 may be configured to include a monitor and display the remaining amount of the battery as a% value.

  The control box 10 is provided with a main power supply 31, a voice recognition on / off switch 32, a dimming knob 33, a voice recognition indicator 35, and a voice recognition answerback speaker 36 on the outer surface of the casing.

  For example, when the main power supply 31 is operated by the operator 40, energization is started to a control unit (described later) in the control box 10. As a result, the medical headlight 1 becomes operable. The voice recognition on / off switch 32 is a switch for selecting whether or not to perform control based on a voice signal input from the operator 40 via the microphone 22. The voice recognition indicator 35 recognizes a voice signal input from the operator 40 via the microphone 22 and outputs an instruction signal corresponding to the voice signal to the control unit. The voice recognition answerback speaker 36 is a speaker that outputs a voice signal corresponding to a warning to that effect when a voice signal input from the operator 40 via the microphone 22 cannot be correctly recognized. Even when the voice recognition indicator 35 correctly recognizes the voice signal input from the operator 40, the voice recognition answer back speaker 36 may output a voice signal to that effect.

  In the present embodiment, the dimming knob 33 includes a knob 33a for dimming the bulb-colored LED element 7a and a knob 33b for dimming the white LED element 7b. By operating the knob 33a, the light amount of the light bulb color in the light included in the light beam 50 is increased or decreased, and by operating the knob 33b, the white light amount of the light included in the light beam 50 is increased or decreased. The That is, the color temperature of the light irradiated to the illumination area | region 51 (refer FIG. 3) can be adjusted by operating the knob 33a and the knob 33b separately.

  FIG. 6 is a block diagram schematically showing the control content of the medical headlight 1. As shown in FIG. 6, a control unit 11 is provided in the control box 10. As described above with reference to FIGS. 1 to 3, the main power supply 31, the voice recognition on / off switch 32, the dimming knob 33, and the voice recognition indicator 35 are provided on the outer surface of the housing of the control box 10. Is provided.

  The control unit 11 includes a current amount determination unit 12 and a power feeding unit 13. The current amount determination unit 12 determines the amount of current to be supplied to the LED elements 7 (7a, 7b) constituting each light emitting surface 60. The power supply unit 13 receives information on the current amount determined by the current amount determination unit 12 and actually outputs the current of the current amount to the cable 23. The current amount determination unit 12 is configured by, for example, a CPU or a microcomputer, and the power supply unit 13 is configured by, for example, a driver. The power feeding unit 13 is electrically connected to a battery built in the battery box 25 via a battery cable 27, and power is supplied from the battery.

  The operator 40 attaches the headband 3 to the head as shown in FIG. 3 and turns on the main power supply 31. When the control unit 11 (current amount determination unit 12) detects that the main power supply 31 is turned on, the control unit 11 (current amount determination unit 12) determines the current amount for the LED element 7 at the initial time point. At this time, the control box 10 includes a storage unit that stores information on the amount of current supplied to the LED element 7 at the initial time, and the current amount determination unit 12 reads the information from the storage unit and determines the amount of current. It does n’t matter what you do.

  The power feeding unit 13 outputs the current of the current amount determined by the current amount determining unit 12 to the cable 23. Thereby, the LED element 7 emits light.

  By the way, depending on the operator 40, there may be a case where the illuminance of the surgical field (illumination area 51) is intentionally increased or decreased during the execution of the medical action on the patient 43. In view of such circumstances, the medical headlight 1 of the present embodiment is equipped with a voice recognition function.

  When the voice recognition on / off switch 32 is in the on state, the voice recognition indicator 35 receives the voice signal from the microphone 22 and converts the voice signal into a predetermined control signal and outputs it to the control unit 11. For example, when the operator 40 says “Up” using the microphone 22, the voice recognition indicator 35 receives a voice signal “Up”, and the controller 11 increases the amount of current supplied to the LED element 7 by a predetermined value. It is converted into an instruction signal indicating that it is to be output. When receiving the signal, the control unit 11 increases the amount of current supplied to the LED element 7 by the predetermined value. Thereby, the illumination intensity of the illumination area | region 51 rises. For example, the illuminance can be further increased by the operator 40 repeatedly speaking a predetermined wording such as “up” using the microphone 22.

  Similarly, for example, when the operator 40 says “down” using the microphone 22, the control unit 11 reduces the amount of current supplied to the LED element 7 by a predetermined value. Thereby, the illumination intensity of the illumination area | region 51 falls. For example, the illuminance can be further reduced by the operator 40 repeatedly speaking a predetermined wording such as “down” using the microphone 22.

  In addition, depending on the operator 40, there may be a case where the color temperature of the surgical field (the illumination area 51) is intentionally increased or decreased during the execution of the medical action on the patient 43. Even in such a case, the voice recognition function can be used. For example, when the operator 40 speaks “white” using the microphone 22, the voice recognition indicator 35 receives the voice signal “white”, and the control unit 11 receives the brightness value of the light bulb color LED element 7 a. The luminance signal ratio of the white LED element 7b is converted into an instruction signal for increasing by a predetermined value and output. When receiving the signal, the control unit 11 changes the amount of current supplied to the LED elements 7 (7a, 7b) so that the ratio of the luminance values increases by the predetermined value. Similarly, for example, when the operator 40 speaks “orange” using the microphone 22, the ratio of the luminance value of the bulb-colored LED element 7a to the luminance value of the white LED element 7b is increased by a predetermined value. The amount of current supplied to the LED element 7 (7a, 7b) is changed.

  Further, the operator 40 may continuously change the color temperature of the illumination area 51 (intermittently) by repeatedly speaking a predetermined word such as “white” or “orange” using the microphone 22. Absent.

  Note that a statement made by the operator 40 during the medical practice may be erroneously recognized by the voice recognition indicator 35, and the illumination mode of the illumination area 51 may change unintentionally. For the purpose of avoiding such a situation, a voice recognition on / off switch 32 is provided. The voice recognition function can be canceled by turning off the voice recognition on / off switch 32 in advance.

[Another embodiment]
Hereinafter, another embodiment will be described.

  <1> In the above-described embodiment, the main body 5 has been described as having the fin 9 formed on the side opposite to the side on which the light emitting surface 60 is formed. However, the fin 9 may be formed on the back side of the light emitting surface 60 on the same side as the light emitting surface 60 in the surface of the main body 5.

  7A and 7B are drawings schematically showing the configuration of the main body 5 according to another embodiment. FIG. 7A corresponds to a perspective view, and FIG. 7B corresponds to a plan view.

  <2> In the above-described embodiment, it has been described that the light emitting surface 60 is arranged so that the optical axis 61 of the light beam emitted from each light emitting surface 60 intersects substantially at one point, that is, in the minute region 62. However, this does not exclude the provision of another light emitting surface (auxiliary light source) having an optical axis that does not pass through the minute region 62 from the present invention.

  FIG. 8 is a drawing schematically showing the configuration of the main body 5 in another embodiment. In the configuration shown in FIG. 8, the main body 5 includes an auxiliary light emitting surface 91 that is different from the light emitting surface 60. The auxiliary light emitting surface 91 is different from the optical axis 61 of the light beam emitted from the light emitting surface 60, and the optical axis 92 of the emitted light beam does not pass through the minute region 62. Here, a case where the light beam emitted from the auxiliary light emitting surface 91 travels substantially straight is illustrated. For example, by being configured in such a manner, the light beam emitted from the auxiliary light emitting surface 91 illuminates a distant area rather than the surgical field, and is used as an illumination for searching for a medical tool or other article in a dark area, for example. can do.

  <3> In each light emitting surface 60 (60a, 60b, 60c), the light distribution may be varied by varying the divergence angle. FIG. 9 is a drawing schematically showing a difference in irradiation mode when the divergence angles are different between the light emitting surface 60a and the light emitting surface 60c. In the example of FIG. 9, the divergence angle of the light emitting surface 60c located at the end with respect to the direction d1 is designed to be wider than the divergence angle of the light emitting surface 60a located at the center. In this case, the irradiation region 64c by the light beam emitted from the light emitting surface 60c is the irradiation region 64a by the light beam emitted from the light emitting surface 60a at the position (the minute region 62) where the optical axis 61a and the optical axis 61c intersect. Wider than.
