Technical Field

[0001] The utility model belongs to the technical field of ophthalmic eye drop application, and specifically refers to an eye drop device for ophthalmology. Background Art

[0002] In ophthalmic treatment, dropping eye drops is a common treatment method. However, there are many problems with the traditional eye drop application method. First of all, during the manual eye drop application process, the patient needs to open the eyelids by themselves and hold the medicine bottle to complete the eye drop. The slight tremors of the hand can easily cause the eye drops to deviate from the eyeball and drip onto the eyelids, cheeks and other parts, which not only causes waste of the medicine, but also reduces the effective dose of the medicine and affects the treatment effect. For the elderly, children or patients with poor hand coordination, this problem is particularly prominent and it is difficult to achieve accurate eye drop application.

[0003] Secondly, the traditional eye drop device lacks an effective eyelid opening assistance structure and cannot ensure that the eyelids are fully opened during eye drop application, making it difficult for the eye drops to enter the eye smoothly. Some patients even have the eye drops squeezed out because they cannot fully open their eyelids, further reducing the utilization rate of the medicine. At the same time, the existing eye drop devices have deficiencies in controlling the amount of eye drops. It mostly relies on the experience and feel of the user and is difficult to accurately control the amount of eye drops dropped each time. An excessive or insufficient amount of medicine may have an adverse impact on the treatment.

[0004] In addition, after the traditional eye drop container is opened, the eye drops are directly in contact with the outside air and are easily invaded by pollutants such as bacteria and dust, posing a risk of deterioration and contamination of the eye drops, which may cause secondary eye infections and threaten the eye health of the patients.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1-6 As shown, the utility model provides an ophthalmic medicine dropping device, comprising an eye mask body 1, wherein two groups of eye groove cavities 2 are symmetrically opened at the bottom of the eye mask body 1, the eye groove cavities 2 are equipped with a medicine dropping assembly 3 and a support rod 4, a pressing portion 5 is slidably penetrated through the eye groove cavity 2, the pressing portion 5 is transmission-connected with the medicine dropping assembly 3, the support rod 4 is symmetrically arranged in two groups in the eye groove cavity 2, the top end of the support rod 4 is hinged to the inner top wall of the eye groove cavity 2, the two groups of support rods 4 are transmission-arranged with the pressing portion 5, and the pressing process of the pressing portion 5 can operate the two groups of support rods to open the eyelids of the user, and at the same time, the medicine dropping assembly 3 is controlled to perform the medicine dropping operation when the pressure reaches a preset value.

[0025] like Figure 1 and Figures 3-5 As shown, the pressing portion 5 is composed of a pressing plate 51, a pressing cylinder 52 and a conical cylinder 53 from top to bottom. The pressing cylinder 52 slides through the top wall of the eye mask body 1 and is placed in the eye groove cavity 2. The pressing plate 51 is fixedly connected to the top end of the pressing cylinder 52, and the conical cylinder 53 is fixedly connected to the bottom end of the pressing cylinder 52.

[0026] like Figures 2-4As shown, the two groups of support rods 4 are arranged in close contact with the sides of the conical cylinder 53, a tension spring 42 is connected between the support rod 4 and the top wall of the eye groove cavity 2, and a support plate 41 is fixedly connected to the bottom end of the support rod 4. When the user presses down the pressing part 5, the conical cylinder 53 slides downward along with the pressing cylinder 52 to penetrate the top wall of the eye groove cavity 2. Since the two groups of support rods 4 are arranged in close contact with the sides of the conical cylinder 53, as the conical cylinder 53 descends, the side of the conical cylinder 53 will gradually squeeze the support rod 4, so that the support rod 4 rotates around the hinge point with the top wall of the eye groove cavity 2. When the support rod 4 rotates, it drives the expansion plate 41 fixed to it to move. The two groups of expansion plates 41 move to both sides respectively, thereby expanding the user's eyelids. When the pressing part 5 is released, under the tension of the tension spring 42, the support rod 4 will rotate in the opposite direction around the hinge point, driving the expansion plate 41 back to the initial position, completing a process of expansion and resetting. It can ensure that a stable expansion force is provided when the eyelids are expanded, ensuring that the eyelids can be fully expanded, facilitating the accurate instillation of drugs into the eyes, and improving the accuracy and effectiveness of drug drops.

[0027] like Figures 2-6 As shown, the medicine dropping assembly 3 includes a medicine storage cartridge 31 and a dropper 32. The medicine storage cartridge 31 is fixedly arranged on the outer side wall of the eye groove cavity 2. A piston plate 311 is slidably arranged in the medicine storage cartridge 31. A piston rod 312 is fixedly connected to the piston plate 311. The piston rod 312 slides through the top wall of the medicine storage cartridge 31. The top end of the piston rod 312 is fixedly connected to a pressing plate 51. A spring 36 is connected between the pressing plate 51 and the top wall of the medicine storage cartridge 31. The dropper 32 is fixedly connected to the bottom of the conical cylinder 53. A medicine delivery tube 33 is connected to the bottom end of the dropper 32 and the medicine storage cartridge 31. A one-way valve is arranged on the medicine delivery tube 33. A dripper 34 is arranged at the bottom of the dropper 32. A diaphragm valve 35 is provided on the dripper 34. When the pressing portion 5 is pressed down, the pressing plate 51 pushes the piston rod 312 to move downward, and the piston rod 312 drives the piston plate 311 to slide downward in the medicine storage cartridge 31. The medicine in the medicine storage cartridge 31 is squeezed, and the medicine is transported to the dropper 32 through the medicine delivery tube 33. When the pressure in the dropper 32 reaches a preset value, the diaphragm valve 35 opens, and the medicine drips out from the dripper 34 at the bottom of the dropper 32 and drips into the user's eyes. After the pressing portion 5 is released, the piston rod 312 is restored to its initial position under the action of the restoring force of the spring 36, and the pressing plate 51 returns to its initial position.

[0028] When in use, the user wears the eye mask body 1 on the eye, ensures that the eye socket cavity 2 corresponds to the eye position, and injects a proper amount of eye drops into the storage cartridge 31. At this time, the spring 36 and the tension spring 42 are in a natural state, and the diaphragm valve 35 is in a closed state;

[0029] When the user presses the pressing plate 51, the pressing plate 51 drives the pressing cylinder 52 and the conical cylinder 53 to move downward. During the downward movement of the conical cylinder 53, the inclined side surface of the conical cylinder 53 squeezes the support rod 4, causing the support rod 4 to rotate around the hinge point with the top wall of the eye socket cavity 2. The support rod 4 drives the spreading plate 41 to move to both sides, thereby spreading the user's eyelids. At the same time, when the pressing plate 51 is pressed down, it pushes the piston rod 312 to move downward. The piston rod 312 drives the piston plate 311 to slide downward in the medicine storage cylinder 31. The medicine in the medicine storage cylinder 31 is squeezed. Due to the one-way valve on the medicine delivery tube 33, the medicine can only flow from the medicine storage cylinder 31 to the dropper 32. As the piston plate 311 squeezes the medicine, the pressure in the dropper 32 gradually increases. When the pressure in the dropper 32 reaches the preset value of the diaphragm valve 35, the diaphragm valve 35 opens, and the medicine drops out from the dropper head 34 at the bottom of the dropper 32 and accurately drops into the user's eye;

[0030] After releasing the pressing plate 51, the restoring forces of the spring 36 and the tension spring 42 cause the piston rod 312 and the pressing part 5 to return to their original positions. The diaphragm valve 35 closes after the pressure decreases, completing a medicine dropping operation.

[0031] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, design structurally similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
