Description

TECHNICAL FIELD

[0001] The utility model relates to ophthalmic medical auxiliary tool technical field, concretely to a kind of ophthalmic wide area imaging handheld photographic device. BACKGROUND

[0002] There are three kinds of ophthalmic wide area imaging handheld photographic devices with different structures on the market, which have the same imaging principle but different structural components.

[0003] The trolley type main machine and imaging handle are adopted, and the scheme only has lens group, image sensor and light guide device in the imaging handle. The trolley type main machine contains light source, computer, display, printer, UPS, isolation transformer, power module and other components. The imaging handle is connected with the trolley type main machine through optical fiber, signal line and power line, and has the advantages of large display, which can be used for multiple people to visit and learn. The printer is integrated, and the user can use conveniently, but has the disadvantages of large size and heavy weight. It is difficult to examine premature infants in NICU, and the space in the aisle of NICU is usually small, so it is troublesome to push the equipment to the side of each patient. The imaging lens has a set of signal line and optical fiber, which is inconvenient for examination. The system has low integration degree, high failure rate and high cost.

[0004] The notebook computer and imaging handle are adopted, and the scheme integrates the illumination light source and lens into the imaging lens. The imaging lens is connected with the main machine through USB, and communication and power supply are completed through the USB interface. The advantages are light and portable, and one small bag can be taken away. The disadvantages are that the power supply is limited by USB, the illumination brightness may be insufficient for patients with dark fundus, and the image quality may be reduced to some extent by increasing the photosensitive value of the sensor. The imaging handle and notebook computer still need cable connection, which is inconvenient to operate in specific environment.

[0005] The handheld main machine is adopted, and the scheme highly integrates lens, light source, embedded mainboard, display screen and battery into a handheld end, without additional computer and connection cable. The advantages are obvious, and the advantages are that all functional components are integrated into a handle, and the cable is removed. In NICU, incubator, blue light treatment bed, multi-room or ward examination, the portability and operability are greatly recognized by users. The disadvantages are that the weight of the current product is about 700g, and the operator will be tired after long time use.
