Description

Technical Field

[0001] This utility model relates to the field of fundus cameras, and in particular to a head-mounted fundus camera. Background Technology

[0002] A fundus camera is a medical device used to capture images of the back of the eye. It is of great significance for the diagnosis, monitoring and treatment of eye diseases. The fundus camera emits light into the eye. After passing through refractive media such as the cornea and lens, the light is focused on the retina at the back of the eye. The light reflected from the retina returns along the same path and passes through the camera's optical system, finally forming an image on the image sensor, thus obtaining a clear image of the fundus.

[0003] Currently, fundus cameras need to be placed on a stand or support platform for use. However, when taking pictures of the bottom of the patient's eyeball, the shooting height of the current fundus camera needs to be adjusted, and it is not portable. Therefore, it is not very flexible to use. To address these issues, we propose a head-mounted fundus camera. Utility Model Content

[0004] The purpose of this invention is to provide a head-mounted fundus camera to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A vertical plate is fixedly connected to the upper surface of the housing, a battery compartment is fixedly installed on the front of the vertical plate, a control panel is fixedly installed on the front of the battery compartment, and a display screen is fixedly embedded in the front of the control panel. The outer side of the housing is provided with a first connecting strap and a second connecting strap. A connecting buckle is fixedly connected to the front of the first connecting strap, and a set of connecting buckle seats is fixedly connected to the back of the second connecting strap, with the outer surface of the connecting buckle adapted to the inner wall of the connecting buckle seats.

[0007] In a further embodiment, the first connecting strip and the second connecting strip are both provided with circular holes on their sides that are close to each other, and two connecting shafts are fixedly connected to the outer surface of the housing.

[0008] In a further embodiment, the ends of the two connecting shafts that are far apart from each other both pass through the circular hole and extend to the outside of the circular hole, and the outer surfaces of the two connecting shafts are rotatably connected to the inner walls of the two circular holes respectively.

[0009] In a further embodiment, a storage battery is fixedly installed on the inner bottom wall of the battery compartment, and a charging socket is fixedly embedded on the upper surface of the battery compartment. The charging socket is electrically connected to the storage battery through a wire.

[0010] In a further embodiment, control buttons are fixedly embedded on the front of the control panel, and the control buttons are electrically connected to the control panel and the display screen respectively via wires.

[0011] In a further embodiment, a first pad is fixedly connected to the outer surface of the first connecting strip, and a second pad is fixedly connected to the outer surface of the second connecting strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention provides power to the device through the battery compartment, and the control panel and display screen allow for the display of images of the patient's fundus, facilitating diagnosis. The first and second connecting straps, along with the connecting buckle and connecting seat, ensure that the fundus camera is securely worn on the patient's head. This head-mounted fundus camera is portable, eliminating the need to adjust the shooting height after being worn on the patient's head, thus improving flexibility during use.
