A larger force is applied to the chemical solution bottle 21 than the force applied by pinching with a finger from the point of action between the holding members 14 and 14 ′.

Next, an eye drop assisting device 30 according to another embodiment will be described with reference to FIGS.
FIGS. 19 (a) and (b) show different types of liquid medicine bottles to be applied to the eye drop assisting device 30. The liquid medicine bottle has a nozzle part and a liquid medicine part formed in two stages and is smaller in size than usual for a small amount of eye drops. Alternatively, it is a liquid medicine bottle 31 for disposable eye drops.
In the eye drop assisting device 30 of the present embodiment, as shown in FIGS. 19 (c) and 20, the pair of holding members 34, 34 'are provided with outward bulges 34a, 34'a at the central portions thereof.

Further, small convex pieces 34b, 34'b are further mounted on the bulges 34a, 34'a of the pair of holding members 34, 34 'by means such as insertion of small projections. Therefore, by pressing the liquid medicine bottle 31 'from both sides, it is possible to perform an eye drop operation from the liquid medicine bottle 31'.
Also in this example, the "leverage principle" is more easily operated when the both ends of the pair of holding members 34 and 34 'are pinched by a finger and the liquid medicine bottle 31' is pressed to perform an eye drop operation. A larger force is applied to the liquid medicine bottle 31 'than the force applied by pinching with a finger from the point of action between the members 34 and 34'.

Hereinafter, other effects of the eye drop assisting device of the present invention will be listed.
A. In conventional products, eye drops (ophthalmic solution) are dropped by pressing a drug solution bottle. However, it is difficult to control the pressing force, and it is difficult to drop the eye drops. In the present invention, by utilizing the "lever principle" in the operation of the pair of holding members, the pressing force can be easily controlled, and the number of drops can be accurately controlled one by one.
B. Because the shape of the head of a drug bottle varies greatly depending on the type, there is a limit on the drug bottles (eye drops containers) that can be used in the case of the conventional eye dropper, but the present invention can handle many drug bottles. Thus, it can be used for almost all drug solution bottles.
C. In the case of a user who has many small drug solution bottles and has a low ability to perform daily living of fingers, it has been difficult to accurately grasp the drug solution bottle. The holding member enables more accurate and firm grip of the liquid bottle.
D. In the case of a patient with reduced visual function, it is difficult to accurately align the tip nozzle of the drug solution bottle with the eye, and a device that adheres to the periphery of the eye has been developed to assist this. However, there are large individual differences in the shape around the eye, and there are large individual differences in accurately attaching the tip of the liquid medicine bottle to the eye. Therefore, it is difficult for a large number of users to cope with a uniform shape. In the present invention, this problem is solved by using an adapter.

Although the present invention has been described as an eye drop assisting device as described above, it goes without saying that it can be diverted to other uses without departing from the gist of the present invention.
