Description

Eye drop instillation auxiliary device Technical Field The invention belongs to the technical field of medical auxiliary equipment, and particularly relates to an eyedrop instillation auxiliary device. Background Ophthalmic is an important branch of medicine, focusing on disease prevention, diagnosis and treatment of the eye and its related structures and the visual system. It covers the prevention, diagnosis and treatment of common vision problems to complex eye diseases. The diseases diagnosed by ophthalmologists are wide in scope, and include refractive errors such as myopia, hyperopia, astigmatism and the like, and blindness-causing eye diseases such as cataract, glaucoma, macular degeneration and the like. In addition, ocular complications caused by systemic diseases such as conjunctivitis, dry eye, and diabetic retinopathy are also included in the technical field. In daily care and treatment of ophthalmic diseases, instillation of eye drops is the most basic and common administration mode, and the operation convenience and instillation accuracy of the eye drops directly influence the treatment effect and the eye comfort level. At present, when patients instill eyedrops by themselves, the patients generally rely on a mode of holding eyedrop bottles for operation, and a plurality of urgent problems exist, namely, firstly, the patients are easy to shake due to tension and disharmony of hand muscles, so that the dripping position of the eyedrops is deviated, not only is the liquid medicine wasted, but also the liquid medicine is not ensured to be accurately dripped into conjunctiva sacs, and the administration effectiveness is reduced, secondly, part of patients receive temporary vision drop after treatment, or the vision of the aged patients and children is poor, the relative positions of bottle mouths and eyeballs of the patients are difficult to accurately judge, the bottle mouths are possibly caused to be too close to each other, even directly touch eyes to cause secondary injuries such as eye irritation and cornea scratch, and meanwhile, if the elevation angle behind the head is not reasonable during instillation, the liquid medicine is easy to drip to non-target parts such as face, eyelid and the like, not only can not exert the medicine effect, but also can not cause skin irritation due to the liquid medicine residue, and cornea irritation reaction can be caused, in addition, the traditional handheld mode has no fixed support, long-time operation leads to arm acid expansion, further influence stability, especially for patients needing instillation, and the accurate instillation is more difficult, and the problems are more difficult to solve the problems of the existing accurate instillation, and the problems are more difficult to solve. Disclosure of Invention Aiming at the above situation, in order to overcome the defects of the prior art, the invention provides an eyedrop instillation auxiliary device, according to the problems of easy hand shake and inaccurate instillation position of hand instillation, a negative pressure fixing and pupil calibrating mode is adopted, a negative pressure adsorption base and a pupil calibrating device are arranged, the technical effects of stable instillation process and accurate alignment of a drip level to a conjunctival sac are realized, the technical problems of liquid medicine waste and low drug administration effectiveness are solved, and in order to solve the problems of easy eye contact and secondary damage of a drug bottle opening during instillation, the invention creatively provides a structure of combining a magnetic suction clamping nozzle with a drug bottle extrusion arm, and the drug bottle opening and the eyeball are kept at a safe distance by fixing the eyedrop bottle through magnetic suction and controlling the extrusion of the drug bottle opening through mechanical transmission, so that the technical effects of direct contact between the drug bottle opening and the eyeball are realized. In order to solve the problems that the conjunctiva sac is shielded by the eyelid and the liquid medicine is easy to drop to the eyelid during instillation, a mechanical support linkage mode is adopted, and an upper eyelid support arm, a lower eyelid support arm and a silica gel anti-slip strip are arranged, so that the technical effects of automatically stretching the eyelid and exposing the conjunctiva sac and ensuring the accurate instillation of the liquid medicine are realized. The technical scheme includes that the eye drop instillation auxiliary device comprises a negative pressure adsorption base, a pupil calibrator and a liquid medicine squeezer, wherein the negative pressure adsorption base is adsorbed on the face of a patient, the pupil calibrator is connected with the negative pressure adsorption base in a sliding mode, and the liquid medicine squeezer is arranged on the negative pressure adsorption base. Further, the negative pressure adsorption bas
