Wherein, the most demanded ophthalmoscope has white light, red light and green light; the otoscope is most in need of white light and red light. In the prior art, the handheld ophthalmoscope and otoscope cannot accommodate a plurality of light sources due to small volume, and when the colors of the light sources need to be changed, the following general types of ophthalmoscopes and otoscopes are selected: 1. changing the detector with different color light sources; 2. replacing the light source on the detector; 3. the detector is provided with a color filter on the path of light emitted from the light source while using a white light source. This first approach is most used in the use of otoscopes. The third mode is generally adopted, that is, the ophthalmoscope is provided with a color film tray with a plurality of color filters in the emission direction of the light source, and different color filters in the color film tray can be positioned on the emission path of the light source by operating the rotation of the color film tray, so that the effect of changing the color of the light source is achieved. The mode makes the structure of detector complicated, and the volume increases, and the color of light is impure and luminance can darken after the light filter simultaneously, is unfavorable for medical science observation. The second approach requires disassembly of the device and is rarely employed.

Detailed Description

As shown in the figure, the embodiment comprises a handle part 1 for holding and a detection head part 2 for medical observation, wherein the two parts are connected by adopting an adaptive interface, a power supply 7, a light source, a switch 5 and a control circuit 4 are arranged on the detector, and the light source is a multicolor LED light source 3.

The control circuit 4 is electrically connected with the power supply 7, the switch 5 and the multicolor LED light source 3, and the switch 5 drives the multicolor LED light source 3 through the control circuit 4.

The multicolor LED light source 3 is internally provided with a plurality of groups of LED light-emitting units, and the control circuit 4 can only drive one group of LED light-emitting units to start at the same time.

At the end of the adaptation interface of the detection head part 2, a receiving space 21 is provided, said control circuit 4 being arranged in the receiving space 21.

In the prior art, the handle part and the detection head part adopt the adapting interface to quickly replace the detection head part with different detection functions, and the mechanical connection between the detection head part and the handle part is realized, and meanwhile, the electric connection between the internal elements of the two parts is realized.

The control circuit 4 comprises a boost filter sub-circuit and a driving MCU sub-circuit, wherein the boost filter sub-circuit keeps the voltage which is transmitted to the LED light source stable, and the driving MCU sub-circuit realizes specific driving switch operation. The utility model can work but has poor use effect if the voltage boosting and filtering subcircuit is not arranged, and the corresponding voltage can be reduced along with the reduction of the electric quantity of the power supply. If the MCU driving sub-circuit is not arranged, the switch in the existing detector needs to be replaced, for example, the switch is replaced by a multi-channel switch, and the corresponding function of driving the LED light source switch can still be realized. However, considering that the switches in the prior art are all single-path on-off switches, in order to avoid replacing the switches in the prior art, the driving MCU sub-circuit can minimize the modification cost.

The LED light emitting units of the plurality of groups need at least two groups, wherein one group of LED light emitting units at least comprises one LED light emitting unit. The same group of LED light emitting units have the same color, and the different groups of LED light emitting units have different colors.

The control circuit 4 in this embodiment can make the LED light emitting units of different groups in the multicolor LED light source 3 be turned on sequentially in the process of turning off and on the switch 5. That is, the switch is turned off once again, and a group of LED light emitting units are turned on in sequence. Thus, the switch structure of the existing detector is not required to be changed.

In order to achieve the light-condensing effect, in the above embodiment, the convex lens 6 needs to be disposed on the path of the light emitted by the multicolor LED light source 3, and the convex lens 6 may be disposed independently or may be formed as an integral structure with the LED light-emitting unit to form a cap-shaped bulb. That is, an in-line multicolor LED, which already has an LED light emitting unit and a convex lens thereon, is commercially available.

In the prior art, an accommodating space is arranged at one end of an adapting interface of the detection head part, and the accommodating space is provided with an opening at the end face, so that after the bulb is placed in the accommodating space, the positive electrode of the bulb can be in output contact with the positive electrode of the power supply of the handle part through the opening, and electric connection is realized.

In order to allow the control circuit 4 to be accommodated in a limited accommodation space, all or part of the control circuit 4 is arranged axially in the accommodation space 21, the end of the control circuit 4 facing in the opening direction being provided with a conductive post 41, which conductive post 41 is electrically connected to the positive input of the control circuit 4.

This arrangement allows the conductive post 41 to withstand a certain pressure, making its electrical connection to the output of the power supply 7 more reliable.

The control circuit 4 may be in the form of a circuit board or a plurality of circuit boards. When the control circuit 4 is in the form of a circuit board, it is arranged axially in the accommodation space 21. When the control circuit 4 is in the form of a plurality of circuit boards, it can be arranged entirely axially in the receiving space 21. Or can be partially axially arranged, and the rest parts are arranged according to the requirements. Thus, when one circuit board cannot accommodate all electronic components, at least part of the circuit board can be axially set up to support the conductive posts 41.
