[0044] When ophthalmologists treat patients, eye drops are an important way of administering medicine. They are easily accepted by patients and widely used. In order to avoid contact infection during clinical use, existing eye drops are generally squeezed and used through ophthalmic drug drop devices.

[0045] In the related art, medical staff or patients themselves need to manually open the upper and lower eyelids and then apply the medicine. During this process, it is easy to bring bacteria from the hands into the eyes. At the same time, some patients have sensitive eyes and are prone to blinking when applying the medicine, causing the medicine to leak out or be contaminated by eyelashes, affecting the normal recovery of the patient's eyes.

[0046] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a portable medicine dropping device for ophthalmic care. When medicine dropping is needed, only the dropper bottle 11 needs to be brought close to the eye, the lever 1 22 is placed on the upper part of the upper eyelid, the lever 23 is moved to the lower part of the lower eyelid, and the user presses the pressing plate 24 with his fingers, and the pressing plates 24 are moved closer to each other, driving the bottom angles of the lever 1 22 and the lever 2 23 to increase, so that the lever 1 22 and the lever 2 23 drive the upper and lower eyelids to separate from each other. At this time, the balloon 25 is pressed to squeeze the gas in the balloon 25 into the hose 26, and the medicine liquid in the hose 26 moves downward and drips onto the surface of the eyeball through the liquid outlet 13 to complete the medicine dropping operation.

[0047] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0048] Combination Figure 1-Figure 4The embodiment of the present application provides a portable ophthalmic care medicine dropping device, including a main body component 1, wherein the main body component 1 includes: a dropper bottle 11 is provided with a liquid inlet 12 at the top, a liquid outlet 13 is provided at the bottom of the dropper bottle 11, and a medicine dropping component 2 is provided on the dropper bottle 11, and the medicine dropping component 2 includes: a pin 21 is provided on the outer wall of the dropper bottle 11, a lever 1 22 is provided on the pin 21, and its middle part is rotatably connected to the pin 21, a lever 23 is provided on the pin 21, and its middle part is rotatably connected to the pin 21, a pressing plate 24 is provided on the top of the lever 1 22 and the lever 2 23, a balloon 25 is provided on the top of the dropper bottle 11, a hose 26 is provided at the bottom of the balloon 25, and the output end of the hose 26 is located at the liquid outlet 13, and the hose 26 is connected to the liquid inlet 12.

[0049] Before use, the liquid medicine is filled into the hose 26 in the dropper bottle 11 through the liquid inlet 12, and the medicine is dripped into the eye using the medicine dripping assembly 2: the user holds the middle of the dropper bottle 11, tilts the patient's head, brings the dropper bottle 11 close to the eye, places the lever 1 22 on the upper part of the upper eyelid, moves the lever 23 to the lower part of the lower eyelid, and presses the pressing plate 24 with the user's finger, and the pressing plates 24 move closer to each other, driving the bottom angles of the lever 1 22 and the lever 2 23 to increase, so that the lever 1 22 The lever 23 drives the upper and lower eyelids to separate from each other, and at this time, the balloon 25 is pressed to squeeze the gas in the balloon 25 into the hose 26, and the medicine in the hose 26 moves downward and drips into the conjunctiva or conjunctival sac in the lower fornix of the eyeball through the liquid outlet 13 to complete the medicine dropping operation. In addition, this dropper bottle 11 is small and convenient for users to carry, which improves the portability of the device. By adjusting the inclination angle of the patient's head, the dripping position of the eye drops in the liquid outlet 13 of the dropper bottle 11 is changed.

[0050] Specifically, the balloon 25 is an inflatable balloon, and an inflation valve is provided on the top of the inflatable balloon 25. After squeezing the balloon 25, the hand is released, and the inflation valve inflates the inside of the balloon 25. The balloon 25 is easy to rebound. At the same time, the inflation valve is a one-way valve to prevent gas backflow, so that the balloon 25 can be used multiple times.

[0051] In some embodiments, the balloon 25 is located between the pressing plates 24. When the user presses the pressing plates 24 to fix the eyelids, when the pressing force is large, the pressing plates 24 squeeze the balloon 25 in the middle to complete the dual actions of fixation and dripping, thereby improving the speed of dripping medicine. When the pressing force is small, such as for patients with smaller eyelid openings such as children, the required pressing force is small, and the pressing plates 24 cannot squeeze the balloon 25. In this case, the balloon 25 needs to be squeezed additionally to drip the medicine.

[0052] In some embodiments, a spring 27 is provided between the pressing plates 24. When the pressing plates 24 are pressed, the springs 27 are compressed. The springs 27 use elastic force to drive the pressing plates 24 to return to their original positions, which is convenient for users to operate.

[0053] In some embodiments, a control component 3 is provided on the dropper bottle 11, and the control component 3 includes: a bidirectional screw rod 31 is provided on the dropper bottle 11, and one end of the bidirectional screw rod 31 extends to the inside of the dropper bottle 11 and is rotatably connected to the inner wall of the dropper bottle 11, a threaded block 32 is sleeved on the bidirectional screw rod 31 and is threadedly connected to the bidirectional screw rod 31, a pressure rod 33 is provided on one side of the threaded block 32, an optical axis 34 is provided inside the dropper bottle 11, and the optical axis 34 passes through the threaded block 32, and a turning handle 35 is fixedly connected to one end of the bidirectional screw rod 31 located outside the dropper bottle 11.

[0054] The control component 3 controls the speed of the medicine dripping out of the hose 26 to adapt to people with different eye sensitivities: when it is necessary to control the speed of the medicine dispensing, the user turns the handle 35, and the handle 35 drives the bidirectional screw 31 to rotate. The threaded blocks 32 threadedly connected on the bidirectional screw 31 approach or move away from each other, and the threaded blocks 32 drive the pressure rod 33 to move to squeeze the hose 26. By controlling the rotation direction of the bidirectional screw 31, the pressure rod 33 can adjust the squeezing degree of the hose 26. After the hose 26 is squeezed by the pressure rod 33, the cross-sectional area of ​​the hose 26 becomes smaller. At this time, the amount of medicine that can pass through is smaller, which reduces the speed of the medicine outflow, thereby adjusting the medicine dispensing speed to adapt to patients with higher eye sensitivity and prevent the medicine from dripping too fast, causing discomfort to the patient.

[0055] In some embodiments, a lever head 221 is disposed at the bottom end of the lever 1 22 and the lever 2 23 . The lever head 221 is made of rubber to prevent the lever 1 22 and the lever 2 23 from causing damage to the eyelids.

[0056] In some embodiments, a side wall of the pressing plate 24 is provided with an anti-slip strip 4, which is made of rubber and has a twill shape. It is located on the opposite side of the pressing plate 24 to increase the friction when the pressing plate 24 contacts the balloon 25, thereby preventing the balloon 25 from sliding when squeezed by the pressing plate 24 and affecting the normal drug dripping process of the balloon 25.

[0057] In some embodiments, a check valve 5 is provided inside the hose 26, and the check valve 5 is mainly composed of a valve body, a valve core, and a sealing ring. The valve body is the main part of the check valve 5, which is usually made of a transparent material to facilitate observation of the flow of the liquid. The valve core is a key component of the check valve 5, which can be automatically opened or closed according to the direction of the liquid flow. The sealing ring plays a sealing role to ensure the sealing performance of the check valve 5. The check valve 5 here is a check valve 5 for infusion, which can be installed inside the hose 26 to prevent the liquid medicine in the hose 26 from flowing back into the balloon 25, affecting the normal use of the balloon 25.

[0058] In some embodiments, the length of the pressure rod 33 is greater than the diameter of the hose 26 to prevent the pressure rod 33 from being unable to completely squeeze the hose 26 due to the larger diameter of the hose 26 when squeezing and limiting the flow, thereby affecting the effect of controlling the amount of medicine discharged.
