Description

Ophthalmic examination head fixing device Technical Field The utility model relates to the field of ophthalmic examination auxiliary equipment, in particular to an ophthalmic examination head fixing device. Background In various ophthalmic examinations, the head of a patient is required to be fixed in a head position fixer of each examination device, in particular, the lower jaw is placed in a mandibular jaw support, the upper forehead is tightly attached to the fixer, and various examinations are started after the head of the patient is fixed in an examination instrument. In the above process, the patient may not be able to match the fixed head position due to pain, or the patient may be unconsciously deviated from the sampling area of the instrument due to the strong light irradiation or air blowing of the instrument, which results in a larger error of the examination result. The utility model discloses a head mount for ophthalmic examination is disclosed to authorization bulletin number CN219323418U, including the head mounting, the head mounting sets up the top at forehead locating part, and the head mounting includes first band, second band and buckle structure, and the one end of first band and second band is movable sleeve respectively establishes on two bracing pieces, and other end swing joint is on buckle structure. According to the technical scheme, the head fixing piece is arranged above the forehead limiting piece, when a patient performs examination, the head of the patient is fixed in the head fixing frame by the head fixing piece, and the patient is prevented from exiting the head fixing frame or shaking in the head fixing frame based on instinct reaction. The above-mentioned solution has been found in practice to be complex in structure and to have a poor effect on the restriction of the movements of the head up and down. Disclosure of utility model The present utility model aims to solve at least to some extent one of the technical problems in the above-described technology. Therefore, the utility model aims to provide a device which has a simple structure and can effectively limit the up-and-down movement of the head of a patient. In order to achieve the aim, the embodiment of the utility model provides an ophthalmic examination head fixing device which comprises a bracket, a constraint assembly, a first transverse constraint component, a second transverse constraint component, a first vertical constraint component and a second vertical constraint component, wherein the bracket comprises two support rods, the constraint assembly comprises a first transverse constraint component, a second transverse constraint component, two ends of the first transverse constraint component and two ends of the second transverse constraint component are respectively connected with the two support rods, the first transverse constraint component and the second transverse constraint component are connected through the first vertical constraint component and the second vertical constraint component, the first transverse constraint component, the second transverse constraint component, the first vertical constraint component and the second vertical constraint component are enclosed to form a fixing hole into which a head is placed, and the first transverse constraint component, the second transverse constraint component, the first vertical constraint component and the second vertical constraint component are made of elastic materials. According to the ophthalmic examination head fixing device provided by the embodiment of the utility model, the restraining component consisting of the elastic bands in the staggered directions is used for restraining the movement of the head of a patient in two directions, and meanwhile, the size of the elastic structure can be automatically adjusted, so that the use steps are simplified, and the structure is simple and firm in fixation. In addition, the ophthalmic examining head fixing device according to the above embodiment of the present utility model may further have the following additional technical features: Optionally, the restraint assembly is divided into two parts by a first lateral restraint and a second lateral restraint provided with a break point, the break point being detachably connected by a connecting element. Further, the connecting element is a velcro or a bayonet catch or a snap. Optionally, the first transverse restraint piece and the second transverse restraint piece are sleeved on the support rod through lantern rings arranged at two ends. Further, the supporting rod is correspondingly provided with a plurality of ring grooves for clamping the lantern rings.
