More specifically, the support part 8 is also included; the supporting part 8 is detachably fixed on the shell 1; the support portion 8 includes an upwardly curved arc-shaped support base plate 81; the supporting bottom plate 81 is higher than the upper medicine liquid hole 312 of the medicine liquid bag 31; a flexible layer is provided on the top surface of the support base 81. Whether to use the support part 8 is determined according to the actual condition of the patient. If the patient's visual line is not clear and the distance between the ophthalmic drip bottle and the eyes is not clear, the support 8 is required. When the support part 8 is used, the support part 8 is arranged on the shell 1, and the support bottom plate 81 is propped against bones above the eye sockets of a patient to drop medicine, so that the distance between the ophthalmic drop medicine bottle and eyes is fixed, the situation that the ophthalmic drop medicine bottle is poked to the eyes of the patient due to excessive force of the patient is prevented, and meanwhile, the patient is helped to judge the distance between the ophthalmic drop medicine bottle and the eyes; the support 8 can be removed when the support 8 is not required, or when an ophthalmic drip bottle is stored. Through the flexible layer that sets up, prevent that supporting baseplate 81 from causing the damage to skin, promote patient's use experience.
More specifically, the casing 1 is provided with a window 9 for observing the eye drop bag 2, and the window 9 is covered with transparent hard plastic so as to observe the condition of the residual liquid medicine in the eye drop bag 2.
In conclusion, the ophthalmic medicine dropping bottle provided by the invention realizes no contact with air before the eye drops flow out of the medicine dropping bottle, eliminates bacterial breeding, thoroughly solves the problem that the antibacterial agent needs to be added in the prior art, and is convenient for medical staff or patients to use.
