Description
Technical Field
The invention belongs to the technical field of medical care instruments, and particularly relates to an appliance capable of assisting a patient to be self-eyed.
Background
The eye disease patients need to regularly use the eye medicine quantitatively, and some patients need to use the eye medicine for a long time. The eyedrops include eyedrops and eye ointments, wherein the eyedrops are generally bottled, namely are contained in a plastic bottle 81, and a tapered dropper 80 is arranged at the front end of the plastic bottle 81, as shown in fig. 1; the eye ointment is generally packaged in a form of a hose, i.e., the eye ointment is contained in a hose body 91, the front end of the hose body 91 is circular, the rear end of the hose body 91 is flat and thin, the front end of the hose body 91 is further provided with a hose nozzle 90, and as shown in fig. 2, the front end surface of the hose nozzle 90 is provided with an extrusion hole. In this document, an eye drop bottle and an eye ointment are collectively called eye drops, a plastic bottle body and a hose body are collectively called an eye drop container body, a dropper of the eye drop and a hose nozzle of the eye ointment are collectively called a container nozzle, and the eye ointment and the eye drop are squeezed downward and drip into eyes to be collectively called eye drops.
The eye drops are preferably applied to the lower fornix of the eyelid. Due to the limitation of objective conditions, patients often need to be self-eyed in families and outpatients, but most of patients with eye diseases are old people or children, and for the part of patients, self-accurate eyed is very difficult, and even normal adults cannot easily and correctly eyed. This is due to: 1. difficulty in accurately controlling the position of the container mouth relative to the eye (including the lower fornix of the eyelid); 2. when the eye drops are applied, the container is suspended in a half-empty state, hands are easy to shake, and the direction of the eye drops during extrusion is uncertain; 3. the extrusion amount of the eyedrops is difficult to control, namely the extrusion amplitude of the eyedrop container body is difficult to control, the extrusion amplitude is too large when a little force is applied, and the extrusion amplitude is too small when the little force is insufficient; 4. the operation is difficult to be carried out by one hand, and the cooperation of two hands is not easy to be tacit.
For the above reasons, the following problems are easily caused: 1. the position of drug delivery is inaccurate, the condition that all or part of eye drugs are dropped outside eyelids often occurs, and the condition that how much drug is leaked outside eyes can not be judged often, and then the eye drugs are not supplemented, and the eye drugs are not supplemented, so that the eye drugs are wasted (some eye drugs are expensive), the curative effect is influenced, and even the eye drugs are possibly dropped inefficiently; 2. the container mouth may contact the eyes and may cause damage or contamination to the already fragile eyes, and the eyes (such as ulcer patients) with germs and bacteria on the eyelashes are easy to contaminate the container mouth and further contaminate the eyedrops; 3. the extrusion amplitude deviation is too large, the dropping amount is not accurate, the curative effect is influenced, and the eye medicine is wasted.
