Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an illumination device for ear, nose and throat examination. Background Technology

[0002] An ENT examination lighting device is a specialized lighting device designed for use during ENT examinations. It provides doctors with a clear field of vision for more accurate diagnosis and treatment. This device is usually designed as a head-mounted or handheld device for easy operation and flexible adjustment of the lighting angle. For convenient use at any time, handheld lighting devices are commonly used. However, handheld lighting devices have a magnetic cap on top. The magnetic cap can not only attach the lighting device to a metal object but also cover the USB charging connector on top of the device. However, the magnetic cap is a separate unit when removed, which makes it easy to lose and fails to protect the USB charging connector. Utility Model Content

[0003] The main objective of this invention is to provide an illumination device for ear, nose, and throat examination, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An ENT examination lighting device includes a main body, a switch movably mounted on the front surface and near the bottom of the main body, a charging indicator light on the upper front surface of the main body, swing arms mounted on both sides of the upper part of the main body, a magnetic cap mounted between the swing arms, and a USB charging connector fixedly mounted on the upper part of the main body.

[0005] More preferably, positioning posts are fixedly installed on both sides of the main body of the lighting device and near the top, and a pen clip is fixedly installed on one end of the positioning post on one side of the main body of the lighting device.

[0006] More preferably, a rod groove is longitudinally formed on the opposite side surface of the swing arm, a guide rod is fixedly installed inside the rod groove, a spring is sleeved on the surface of the guide rod and located below it, a sleeve hole is formed at the lower end of the swing arm, and a flip groove is formed on the surface of the swing arm on one side of the lighting device body and located below it.

[0007] More preferably, a sliding sleeve is fixedly installed on both sides of the magnetic cap and on the lower side, and the sliding sleeve is sleeved on the guide rod above the spring.

[0008] More preferably, the lower end of the spring is fixed to the lower inner surface of the rod groove, the upper end of the spring is fixed to the sliding sleeve, and the magnetic cap covers the upper part of the lighting device body.

[0009] More preferably, the positioning post passes through the sleeve hole.

[0010] Compared with the prior art, this utility model proposes an illumination device for ear, nose and throat examination, which has the following beneficial effects: In this invention, by setting up a lighting device body, a magnetic cap, and a swing arm that work together, when the device needs to be charged, the magnetic cap is pulled up. When the magnetic cap is pulled up, it stretches the spring inside the swing arm until the magnetic cap rises to its maximum limit. Then the swing arm can be flipped up, so that the magnetic cap flips up to expose the USB charging connector. The magnetic cap is always connected to the lighting device body through the swing arm, so it will not be lost. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figure 1-3As shown, an ENT examination lighting device includes a lighting device body 1, a switch 4 is movably mounted on the front surface of the lighting device body 1 near the bottom, a charging indicator light 3 is provided on the upper front surface of the lighting device body 1, swing rods 6 are mounted on both sides of the upper part of the lighting device body 1, a magnetic cap 2 is installed between the swing rods 6, and a USB charging connector 5 is fixedly mounted on the upper part of the lighting device body 1.

[0017] In a preferred embodiment, positioning posts 101 are fixedly installed on both sides of the main body 1 of the lighting device and near the top, and a pen clip 102 is fixedly installed on one end of the positioning post 101 on one side of the main body 1 of the lighting device.

[0018] In the above structure, the pen clip 102 allows the main body 1 of the lighting device to be clipped onto the clothing of medical staff, making it convenient to access at any time.

[0019] In a preferred embodiment: a rod groove 601 is longitudinally formed on one side surface of the swing rod 6, a guide rod 602 is fixedly installed inside the rod groove 601, a spring 603 is sleeved on the surface of the guide rod 602 and located below it, a sleeve hole 604 is formed at the lower end of the swing rod 6, and a flip groove 605 is formed on the surface of the swing rod 6 on one side of the lighting device body 1 and located below it.

[0020] In the above structure, the spring 603 is in a compressed state under natural conditions, and the elastic coefficient of the spring 603 must ensure that the magnetic cap 2 will not expose the USB charging connector 5 without a large upward pulling force. This can ensure the protective effect of the magnetic cap 2 on the USB charging connector 5, and the lighting device can be attached to a metal object by the magnetic cap 2.

[0021] In a preferred embodiment, a sliding sleeve 201 is fixedly installed on both sides of the magnetic cap 2 and located below it. The sliding sleeve 201 is sleeved on the guide rod 602 above the spring 603.

[0022] In a preferred embodiment: the lower end of the spring 603 is fixed to the lower inner surface of the rod groove 601, the upper end of the spring 603 is fixed to the sliding sleeve 201, and the magnetic cap 2 covers the upper part of the lighting device body 1.

[0023] In a preferred embodiment: the positioning post 101 passes through the sleeve hole 604.

[0024] In the above structure, the positioning post 101 has a limiting effect on the swing arm 6, so that when the swing arm 6 is flipped, it can only swing around the positioning post 101 as the center.

[0025] When this utility model is in use, if the device needs to be charged, pull up the magnetic cap 2. When the magnetic cap 2 is pulled up, it will stretch the spring 603 inside the swing arm 6 until the magnetic cap 2 rises to its maximum limit. Then the swing arm 6 can be flipped so that the magnetic cap 2 exposes the USB charging connector 5. The magnetic cap 2 is always connected to the main body 1 of the lighting device through the swing arm 6, so it will not be lost.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
