Abstract
Description
[Technical field]
[0001] The present invention relates to a medical headlight system used in examining and operating on patients in a hospital's surgery, dentistry, ENT department, etc. More specifically, the present invention relates to a neckband type medical headlight system that improves convenience of use and prevents cross-infection of bacteria and viruses by turning the headlight on and off with a foot instead of a hand and adjusting the brightness of the headlight by moving the neck without using hands. [Background technology]
[0002] Medical headlights used in hospitals for patient examinations and surgery generally consist of a magnifying glass (also called a loupe) attached to glasses or a headset, a headlight that emits light, and a controller for adjusting the headlight.
[0003] The headlights are configured with LEDs having high illuminance, and the controller controls the on / off and brightness of the headlights.
[0004] Such medical headlights can be divided into wired large-capacity battery types, in which the large-capacity battery and headlight are connected by a cable and the large-capacity battery is worn on the waist, and wireless small-capacity battery types, in which the battery and controller are miniaturized and integrated into the glasses.
[0005] FIG. 1 shows an example of a wired, large-capacity battery type headlight, in which a lighting unit 1 is attached to glasses 3 equipped with a magnifying glass 4, and an optical unit 2 is provided in front of the lighting unit 1 to focus the light emitted from the lighting unit 1 in a certain area.
[0006] The lighting unit 1 is attached to the glasses 3 by a bracket 6.
[0007] The lighting unit 1 is connected to a control unit 7 by a power cable 5 , and the control unit 7 includes an operation switch 71 , a large-capacity battery 72 , and a control PCB 73 .
[0008] Thus, the medical staff can view the treatment area brightly and enlarged through the lighting unit 1 and the magnifying glass 4 while wearing the control unit 7 on their waist.
[0009] The wired high-capacity battery method has the advantage that the battery can be used for a long time.
[0010] However, in the wired high-capacity battery system, the control unit 7 worn on the waist and the lighting unit 1 are connected by a power cable 5.
[0011] This requires a separate clip (not shown) to secure the power cable 5 to the surgical attire, or a band to secure the power cable 5 to the frame of the glasses 3, and has the disadvantage that it takes a considerable amount of time to put on and take off the headlight.
[0012] In addition, when using the headlights, the operating buttons of the lighting unit are frequently touched, which poses the risk of infection from bacteria or viruses in the operating room or examination room, and there is a risk of cross-contamination in which such bacteria or viruses are transferred to a third patient or location.
[0013] On the other hand, in the wireless battery-powered type, as shown in FIG. 2, a small capacity battery 8, a control PCB, and a lighting unit 1 are integrated into the glasses 3.
[0014] The wireless small capacity battery method has the advantage that it is easy to install on the headlight since it does not require a separate power cable.
[0015] However, because the battery is attached to the glasses, the weight of the battery can make the user feel fatigued, and the battery capacity is limited, meaning it can only be used for 2 to 3 hours.
[0016] In addition, since the operation button must be frequently touched to turn the lighting unit on and off, there is a high possibility of bacterial contamination and cross-contamination in the operating room and examination room. Summary of the Invention [Problem to be solved by the invention]
[0017] The present invention is intended to solve the above-mentioned problems of the prior art, and has an object to enable a user to quickly and easily wear and use a headlamp and to enable the headlamp to be used for a long period of time.
[0018] Another object of the present invention is to eliminate the need for a user to operate the lighting unit by touching it with his / her hands, thereby eliminating the risk of contamination and cross-contamination by various bacteria.
[0019] It is still another object of the present invention to enable a user to easily adjust the brightness of a headlight without touching a control unit with his or her hand.
[0020] It is still another object of the present invention to provide a user with various information regarding the degree of neck fatigue. [Means for solving the problem]
[0021] In order to achieve the above object, the present invention provides a medical headlight system including a lighting unit and a magnifying glass provided in glasses or a headset, a control unit for controlling the lighting unit, and a battery and a power cable for supplying power to the lighting unit, wherein the control unit for controlling the lighting unit is configured as a neckband type and is placed around a user's neck, and further includes a pedal-type wireless control unit so that the user can turn the lighting unit on / off using his / her foot.
[0022] The neckband type control unit is characterized by having a main PCB provided on one side and an auxiliary PCB provided on the other side.
[0023] The main PCB of the control unit is characterized by including an RF antenna for wireless communication with the pedal-type wireless control unit and a smartphone, and a buzzer that generates a warning sound when the user is in an incorrect posture.
[0024] The control unit is also provided with a socket-type magnetic connector on one side thereof to which one end of a power cable can be attached.
[0025] The batteries are provided on both ends of the neckband type control unit, and are push-type mounted and detached from the control unit by a latch-type locker.
[0026] The power cable is also characterized in that one end thereof is provided with a plug-type magnetic connector for assembly with a socket-type magnetic connector of a control unit, and the other end thereof is provided with a plug-type connector for connection with a connector of a lighting unit.
[0027] The control unit is also characterized by having two low-loss diodes and by preferentially selecting and using the battery with the higher voltage of the two batteries.
[0028] The lighting unit is also characterized by having a 9-axis sensor to recognize the user's movements and control the lighting unit based on the movements.
[0029] The nine-axis sensor is characterized by including three acceleration sensors and a three-axis gyro sensor.
[0030] Another feature is that the lighting unit is turned on or off when the user moves their head up and down twice within 2 to 3 seconds.
[0031] In addition, if the user moves their head up and down once within 2 to 3 seconds, moves their head to the right and then returns to the center, the brightness of the lighting unit is increased by one level.
[0032] In addition, if the user moves their head up and down once within 2 to 3 seconds, moves their head to the left and then returns to the center, the brightness of the lighting unit is reduced by one level.
[0033] In addition, if the user's neck is excessively lowered beyond a certain angle and this posture is continuously maintained, a buzzer in the control unit will sound to warn the user.
[0034] The lighting unit is characterized in that it can be turned on / off or its brightness can be adjusted by PWM control of the control unit.
[0035] The headlight system also works in conjunction with a smartphone app to store the user's neck angle and analyze the degree of neck fatigue by date and time.
[0036] Another feature is that the control unit's settings can be changed using a smartphone app.
[0037] The pedal-type wireless control unit is also characterized by including an RF antenna for wireless communication with the control unit, a DIP switch for setting a unique number for the pedal, a hinge for allowing the top cover to rotate at a certain angle, a spring for supporting the top cover, and a battery for supplying power to the pedal-type wireless control unit.
[0038] Also, the present invention is characterized in that malfunction of the headlight system is prevented by setting specific values for the dip switches of the pedal type wireless control unit and the dip switches of the control unit. Effect of the Invention
[0039] According to the present invention, the control unit is configured as a neckband type that is worn around the neck, which has the effect that the user can quickly and easily wear and use the control unit.
[0040] In addition, since the power cable connecting the lighting unit and the control unit is short, there is no need to use a separate clip or band when wearing the headlamp.
[0041] This has the effect of reducing the time it takes to put on and take off the headlamp.
[0042] In addition, since the lighting unit is turned on / off by stepping on the pedal with the foot, it is possible to improve the convenience of use.
[0043] In addition, a 9-axis sensor is applied to the lighting unit, and the brightness of the headlights is adjusted according to the movement of the neck during use, eliminating the need to operate buttons with one's hands.
[0044] In addition, since the control unit can be operated without using hands, it is possible to prevent bacterial contamination and cross-contamination in the operating room or examination room.
[0045] In addition, since the batteries are provided in both the control units, the user's fatigue caused by the weight of the batteries is reduced and the usage time of the headlamp can be extended.
[0046] In addition, by providing a low-loss diode at the input terminal of the battery power supply, it is possible to prevent reverse current flow caused by using two batteries, and it is possible to give priority to the battery with the higher power supply.
[0047] Another benefit is that the headlights can continue to be used even if one of the two batteries is removed.
[0048] In addition, each part is modularized so that only the relevant parts can be replaced, which simplifies maintenance and repair.
[0049] In addition, the thermal buffer PCB prevents the high temperature generated by the LED PCB from being directly transferred to the lighting unit PCB.
[0050] In addition, by using a point-contact type connector when transmitting electrical signals to each PCB, it is possible to minimize heat conduction in lighting units that use high power.
[0051] In addition, by adjusting the brightness of the lighting unit through the PWM control of the control unit, it is possible to realize various brightness intensities without a separate rotary variable resistor.
[0052] In addition, if the user's neck is tilted too far, a warning is issued, which has the effect of guiding the user to perform treatment in a stable posture.
[0053] In addition, by using the headlight in conjunction with a smartphone, it is possible to provide various information regarding the user's level of neck fatigue. [Brief description of the drawings]

[0055] Preferred embodiments of the present invention will now be described in detail with reference to FIGS.
[0056] As shown in FIG. 3, the medical headlight system according to the present invention includes a neckband-type headlight control unit 100, a lighting unit 200, and a pedal-type wireless control unit 300.
[0057] First, a headlight control unit 100 according to the present invention will be described.
[0058] As shown in Figures 4 to 7, the neckband-type headlight control unit 100 (hereinafter simply referred to as the "control unit") according to the present invention includes a main PCB unit 110 provided on one side, an auxiliary PCB unit 130 provided on the other side, a cable wire 140 that electrically and signal-connects the main PCB unit 110 and the auxiliary PCB unit 130, a top cover 151 that structurally fixes the components, a bottom cover 150, an elastic connector 152, and a fastening screw 153.
[0059] In the present invention, the control unit 100 is configured in the form of a neckband.
[0060] This makes the headlamp very easy to wear since all that is required is to hang the control unit 100 around the neck.
[0061] The main PCB unit 110 includes an MCU 112 for controlling the overall operation of the device, an LED 111 for displaying the remaining charge of the batteries 122, 135 and the device status, a lock switch 113 for preventing unnecessary button pressing during use, an up / down switch 114 for adjusting the brightness of the high brightness LED 211 of the lighting unit 200, a DIP switch 115 for setting the unique number of the pedal to be received among the signals sent from multiple pedals, a power button 116 for turning on / off the entire power supply of the control unit 100, a buzzer 117 for notifying the operating status of the device, and a flash memory for recording the values of the 9-axis sensor 223 of the lighting unit 200 by date and time. The pedal-type wireless control unit 300 includes a memory 118, a connector 119 that connects signals to the lighting unit 200, an RF antenna 120 that receives wireless signals transmitted from the pedal-type wireless control unit 300 and performs wireless communication with a smartphone, a contact-type connector 121 that receives battery power, and batteries 122 and 135 that supply power.
[0062] As shown in FIG. 8, the batteries 122 and 135 are mounted on both ends of the control unit 100 and are detachable by a latch-type locker 140.
[0063] The lower ends of the batteries 122 and 135 are seated in the battery holder 122-1 so as to be fixed by the latch-type locker 140.
[0064] In addition, a protrusion 122-1 is provided on one side of the battery holder 122-1 so that the battery holder 122-1 can be firmly fixed to the latch-type locker 140.
[0065] The latch-type locker 140 is constructed in a push lock, push release manner, and for this purpose, a compression spring 141 is provided inside, and a clearance space for unlocking is formed at the upper end of the battery.
[0066] It is preferable that the LED 111 provided on the main PCB 110 indicates the remaining battery level by color. For example, the remaining battery level can be displayed in three levels: blue, purple, and red.
[0067] The buzzer 117 notifies the user of the completion of settings made by pressing a switch or button through various sound sources.
[0068] The auxiliary PCB 130 is provided on the opposite side of the main PCB 110 and includes an LED 131 that indicates the connection status with a smartphone, a correction button 132 for setting the origin reference of the 9-axis sensor, a setting switch 133 for setting the on / off of a specific function, a contact-type connector 134 that receives battery power, and a battery 135 that supplies power.
[0069] As shown in FIG. 6, the rear face of the control unit 100 is provided with a dip switch 115 for setting the unique number of a pedal from which data is to be received among a large number of pedals.
[0070] The DIP switch is provided to prevent malfunction when multiple pedal-type wireless control units 300 are used.
[0071] For example, if the numbers of the dip switches 314 of multiple pedal units 300 are set to 0001, 0011, 0111, 1111, etc., and the number of the dip switch 115 of the control unit 100 is set to 0001, the control unit 100 will only respond to the pedal unit 300 set to number 0001 and will ignore signals from the other pedal switches.
[0072] By setting the numbers as described above, a single control unit 100 can be used with multiple pedal units 300 distributed in various locations.
[0073] In addition, when two or more control units 100 and the pedal type wireless control unit 300 are used in the same space, malfunctions can be prevented.
[0074] Next, a lighting unit 200 of the present invention will be described with reference to FIGS.
[0075] The lighting unit 200 according to the present invention is provided in the glasses 3 and is connected to the control unit 100 via a power cable 5, and has a function of emitting high-intensity light and recognizing a user's gesture.
[0076] The lighting unit 200 includes an optical unit 2, a lighting unit PCB 220 that controls high-brightness LEDs 211 and recognizes user gestures using a 9-axis sensor, an LED PCB 210 including the LEDs 211 that emit high-brightness light, a thermal buffer PCB 230 that ensures that high-temperature heat generated on the rear surface of the PCB is not directly transmitted to the lighting unit PCB 220 but only electrical signals are transmitted, and fixture cover modules 213, 214, 231, 225, and 226.
[0077] The lighting unit 200 also includes a socket-type connector 221 for receiving a control signal from the control unit 100 and receiving power supply, an LED driver 224 for adjusting and maintaining constant brightness of the high brightness LED 211, a 9-axis sensor 223 for measuring the angle and rotation of the user's neck, instantaneous fluctuations in movement, etc. to recognize the user's gesture, and a contact-type connector 222 for transmitting an electrical signal to the heat buffer PCB 230.
[0078] Here, it is preferable that the nine-axis sensor includes three acceleration sensors and three gyro sensors.
[0079] The heat buffer PCB 230 is located between the LED PCB 210 and the lighting unit PCB 220, and functions to prevent high temperature heat generated in the LED PCB 210 from being directly transferred to the lighting control unit PCB 220 and to transfer only electrical signals.
[0080] The LED 211 is a high-power, high-brightness LED having a power consumption of 1 W or more, and is provided with a contact-type connector 212 on the rear surface for connection to a heat buffer PCB 230 .
[0081] As shown in FIG. 9, the lighting unit 200 is connected to a control unit 100 via a power cable 5.
[0082] As shown in FIG. 10, the power cable 5 includes a plug-type connector 119-1 that is coupled to a connector 119 of the main PCB, and a plug-type connector 221-1 that is coupled to a connector 221 of the lighting unit PCB.
[0083] Although the power cable 5 may have problems such as breakage during use, the connector allows easy replacement of only the damaged cable. In order to make the connector easy to attach and detach, the connector is preferably of a magnetic type.
[0084] Furthermore, in the present invention, since each component is modularized, when a defect occurs in a module, only the corresponding component can be replaced and used.
[0085] In addition, since electrical and signal transmission between the PCBs is performed by the point-contact type connectors 212 and 222, heat conduction can be minimized.
[0086] Next, the pedal-type wireless control unit 300 of the present invention will be described.
[0087] As shown in Figures 3, 12 to 14, the pedal-type wireless control unit 300 according to the present invention includes an RF antenna 311 for wirelessly transmitting user pressing information to the control unit 100, a switch 312 for recognizing pressing information of an upper cover 318 of the pedal, an MCU 313 for grasping the pressing information of the upper cover 318 and recognizing unique information of the pedal to control a pedal PCB 310, a DIP switch 314 for setting unique values so that a plurality of pedal-type wireless control units can be distinguished from one another, an LED 316 for displaying to the user that the upper cover has been pressed and that an RF transmission state is in progress, a battery 317 for supplying power to the pedal PCB 310, and a connector 315 for connecting the power of the battery 317 to the pedal PCB 310.
[0088] The pedal type wireless control unit 300 is placed on the floor when in use. When the user presses the top cover 318 with his / her foot, the switch 312 is energized and the MCU 313 transmits the pressed state to the control unit 100 via the RF antenna 311 .
[0089] At this time, the setting value of the DIP switch 314 is transmitted together with the switch pressing information. This allows the control unit 100 to operate only if it has the same setting value as the pedal type wireless control unit 300.
[0090] Since the top cover 318 that comes into contact with the user's foot and the bottom cover 319 that fixes the pedal PCB are made of a metal material such as aluminum, the radio waves of the RF antenna 311 may be subject to interference.
[0091] For this reason, it is preferable to configure the RF antenna 311 on a separate PCB and place it on the upper end of the pedal-type wireless control unit 300, and apply a plastic cover 320 that does not cause problems in radio communication.
[0092] In addition, in the present invention, the LED 316 for informing the user of the state of the pedal being pressed and the RF antenna 311 are formed on a separate PCB, which is attached to the upper corner of the pedal where there is no metal material.
[0093] A compression spring 322 is provided inside the pedal unit to quickly restore the pressed state of the upper cover, and a hinge member 323 is provided on one side for rotating the upper cover. Also, an anti-slip pad 326 is provided on the bottom of the pedal unit.
[0094] 13, a dip switch 314 for setting specific settings is provided on the rear of the pedal. The dip switch 314 allows the user to set various settings.
[0095] In the present invention, as shown in FIG. 15, low-loss diodes 123 and 136 are provided at the INPUT portion of the battery power supply in the main PCB 110 of the control unit 100 to prevent reverse current flow due to the use of two batteries.
[0096] The low-loss diode is an electrical element that allows current to flow in only one direction, and the low-loss diode allows the power source of the battery having a higher voltage to be used preferentially.
[0097] Even if one of the batteries is removed, power can be continuously supplied through the other battery.
[0098] In addition, in the present invention, as shown in FIG. 18, the MCU 112 of the control unit and the LED driver 224 of the lighting unit are signal-connected via a power cable 5, and the MCU 112 can control the LED driver 224 by signal modulation using a PWM (Pulse Width Modulation) method.
[0099] That is, the LED driver 224 adjusts the amount of current applied to the LED 211 according to the duty cycle of the PWM, thereby adjusting the brightness.
[0100] According to the above control method, the brightness intensity of the high brightness LED 211 can be varied without a separate rotary type variable resistor.
[0101] The use of the headlight system according to the present invention will now be described.
[0102] A user of the headlamp wears glasses equipped with a lighting unit 200 and a magnifying glass 4 on his / her eyes, and wears the control unit 100 around his / her neck, as shown in FIG.
[0103] Here, the control unit 100 and the lighting unit 200 are connected to each other by a wired cable 5. And the pedal type wireless control unit 300 is placed on the floor.
[0104] When a user presses the power button 116 for a certain period of time, power is applied to the entire system, and the MCU 112 of the control unit 100 controls the LED driver 224 of the lighting unit 200, through which power is applied to the high brightness LED 211, which emits light.
[0105] Then, when the up-down switch is moved up or down, the MCU modulates the PWM signal and sends it to the LED driver 224, which recognizes it and adjusts the brightness of the LED.
[0106] At this time, it is preferable to use the lock switch 113 to set locking for various switches and buttons so that the light is not turned off unintentionally during surgery or medical treatment.
[0107] The mounting position and orientation of the lighting unit may differ from user to user, which causes the origin of the 9-axis sensor of the lighting unit PCB to vary.
[0108] Therefore, after attaching the lighting unit to the glasses, the user must reset the origin of the 9-axis sensor based on the user's wearing state.
[0109] To do this, the user presses the correction button 132 for a certain period of time to cause the MCU 112 to carry out this series of operations.
[0110] The user can also activate or deactivate the performance of tasks such as gesture recognition of the 9-axis sensor, saving the neck angle, and connecting (pairing) with a smartphone via the setting switch 133.
[0111] When the setting switch 133 is activated, the gesture function of the 9-axis sensor 223 is initiated.
[0112] The 9-axis sensor 223 measures the user's neck angle, neck rotation, instantaneous movement speed, etc., and transmits the results to the MCU 112 .
[0113] Based on this movement, the MCU 112 adjusts the brightness of the lighting units and turns them on and off.
[0114] Hereinafter, a process of turning on / off the lighting unit and adjusting the brightness by a user's gesture will be described with reference to FIG.
[0115] First, when the user puts on the headlamp and moves their head up and down twice within 2 to 3 seconds, the lighting unit is turned on and off alternately.
[0116] Here, if the time the user moves his / her neck exceeds a certain period of time or if the movement is not an exact up and down movement, this will not be recognized.
[0117] If the user moves their head up and down once, to the right and then back to the center within 2 to 3 seconds, the lighting unit will increase the brightness by one level.
[0118] Additionally, if you move your head up and down once, to the left once, and then back to the center within 2 to 3 seconds, the lighting unit will reduce the brightness by one level.
[0119] The MCU also stores neck angle information from the acceleration sensor by date and time in the flash memory 118, and transfers the corresponding information by calling the smartphone APP 1001 when necessary.
[0120] The smartphone app uses the user's neck angle information as a basis to statistically analyze the degree of neck fatigue caused by keeping one's head down for long periods of time, and provides the user with a variety of information, such as appropriate exercise therapy.
[0121] That is, as shown in FIG. 17, the smartphone app can notify the user of the neck angle and the usage time of dangerous neck angles or warning neck angle sections in real time during a newly started task, and can provide the user with statistical information for a day, week, month, and year.
[0122] Meanwhile, settings such as dangerous neck angle ranges, whether or not to issue a warning, and brightness levels can be set on the smartphone APP 1001 and applied to the control unit 100 connected via RF.
[0123] According to the present invention, since the control unit is configured as a neckband type, it becomes very easy to wear and use the headlamp.
[0124] In particular, the length of the power cable connecting the control unit and lighting unit is shortened, minimizing the inconvenience of using a power cable even when using a wired battery system.
[0125] You can also turn the lighting unit on and off with your feet without using your hands, and the 9-axis sensor allows you to adjust the brightness of the lighting unit just by moving your neck.
[0126] This eliminates the need for the user to manually operate the headlight during surgery or medical treatment, eliminating the risk of contamination and cross-contamination by various bacteria.
[0127] The use of two batteries also extends the operating time, and low-loss diodes are provided to give priority to the higher power battery.
[0128] In addition, by applying a dip switch, malfunctions of the control unit and the pedal-type wireless control unit can be prevented.
[0129] Furthermore, the magnetic connectors allow the power cable to be easily assembled to the control unit and lighting unit, and modularizing each part simplifies part replacement and maintenance and repair.
[0130] Additionally, by linking the headlight to a smartphone, it is possible to provide various information about the user's neck movements.
[0131] The above is an illustrative description of the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above specific embodiment. Those skilled in the art will understand that various modifications and changes can be made without departing from the scope of the technical idea of the present invention.
