Description

Novel adjustable medical magnifier

Technical Field

The utility model belongs to the technical field of the technique and specifically relates to a medical magnifying glass with adjustable it is novel.

Background

The skin diseases occur in the skin and mucous membrane of the body surface, the skin damage is visual, but the primary skin damage and the secondary skin damage are various, the skin diseases are various and easy to misdiagnose, therefore, the patient needs to be carefully observed and identified, so that the dermatologist usually observes the affected part of the patient by means of tools such as a magnifying glass, a flashlight, a measuring scale and the like, while the distance between the lens and the skin needs to be manually mastered when the common hand-held magnifying glass is used at present, if the user holds the glasses unstably or observes the glasses for a long time, the distance between the glasses and the skin cannot be kept at a proper distance easily, the observation effect and the accuracy of comparison between the front and the back of the inspection result are influenced, and at present, many doctors use daily magnifying glasses without arranging a light source device and a measuring device, the function is single, and the effect of accurate observation can be achieved by combining other devices, so that the use is inconvenient.

The Chinese patent application: CN202875481U discloses a special magnifying glass of dermatosis diagnosis and treatment, has basic magnifying glass, and basic magnifying glass periphery sets up the LED lamp, and basic magnifying glass sets up light luminance knob with the handle junction, sets up the battery on the handle as the power, and the tip installation pencil under the handle, along handle length direction sets up the scale. The device mainly solves the problem that the traditional magnifier is single in function and brings inconvenience to clinical work. However, the LED lamp in the device can only supplement the observation effect of the rash when the natural light is insufficient, but for skin diseases such as vitiligo, tinea versicolor, and erythrasma, the characteristics of the disease can be displayed under the ultraviolet lamp, so the ideal effect of auxiliary diagnosis of the disease can not be achieved, and the device can not keep the distance between the lens and the skin at a proper distance for a long time when being used, and the accuracy of the front-back comparison of the observation effect and the inspection result is easily affected (i.e. if the distances of the rash observation and the photographing are different, the size of the rash in the vision is different).

The Chinese patent application: CN206565933U discloses a multifunctional magnifier suitable for skin disease diagnosis, comprising a magnifier sleeve and a magnifier body; in the magnifier sleeve, a clamping end is connected with a fixed end through threads, and a grafting ring is arranged on one side of the tail part of the clamping end; the tail end of the head of the magnifier body is provided with a magnifier body control rod to form the magnifier body, lenses are arranged in a lens frame in the head of the magnifier body, LED lamps are distributed on the lens frame in an array manner, one side of the magnifier body control rod is provided with a power switch, the other side of the magnifier body control rod is provided with an infrared lamp, a scale mark is arranged between the power switch and the infrared lamp, and a dry battery pack is arranged in the magnifier body control rod; the magnifying glass cover cylinder cup joints on magnifying glass body control lever, the device mainly solves the technical problem that can't carry out the skin disease observation effectively under the poor condition of light condition, but the setting of led lamp can only supply the effect of skin rash observation when natural light is not enough among the device, to skin diseases such as leucoderma, tinea versicolor, erythrasma, can show the disease characteristic under the purple light lamp, so can not reach the ideal effect of auxiliary diagnosis this type of disease, and the device can not let the distance between lens and skin keep at a suitable distance for a long time using, influence the degree of accuracy of contrast around observation effect and the inspection result very easily (if the skin rash is observed, the distance of shooing is different, the vision goes up the skin rash size and has the difference).

Therefore, in summary, there is a need for a novel adjustable medical magnifier which is convenient for doctors to project grid lines at the skin through a projection lamp and then measure the grid lines to visually obtain the skin damage, can keep a proper distance between a lens and the skin, improves the accuracy of observation effect and inspection result, is more convenient to use, and has no report at present about the novel adjustable medical magnifier.
