The indication component includes a partition frame 16 and a baffle 12 provided in the mounting frame 1, and the mounting frame 1 is divided into a plurality of indication areas along the circumferential direction by the partition frame 16. The drug spraying head 14 is provided in the middle of the partition frame 16, and the baffle 12 is made of a transparent material, and an indication point 13 is provided on the baffle 12 corresponding to each indication area.

[0062] When the device is in use, it can be worn in the same way as wearing glasses, so that the support frame 11 is placed on the patient's ear, and the position of the support frame 11 is adjusted to align the spray head 14 with the central area of ​​the eye. The spray head 14 can spray liquid medicine, and during the medication process, the eyeball can be controlled to look at the indicator point 13 in the opposite direction according to the diseased position, so that the diseased position is exposed and the eyeball's attention is diverted, avoiding eyelid closure due to stress response during the medication process, so as to achieve the purpose of accurately applying medicine to the local position of the eyeball.

[0063] like Figures 3 to 5 As shown, in this embodiment, a piston cylinder 25 is arranged in the mounting groove 15, a slidable piston plate 41 is arranged in the piston cylinder 25, a medicine storage bottle 21 is arranged on the mounting frame 1, and the medicine storage bottle 21 is connected to the medicine spraying head 14 and the piston cylinder 25 through a medicine supply assembly, and the reciprocating sliding of the piston plate 41 is converted into supplying the liquid medicine in the medicine storage bottle 21 to the medicine spraying head 14 through the medicine supply assembly. The medicine supply assembly includes a mounting sleeve 2 arranged on the support frame 11, one end of the air supply pipe 24 is connected to the piston cylinder 25, and the other end is connected to the mounting sleeve 2 through the air outlet check valve 23, and extends into the medicine storage bottle 21, an air intake check valve 26 is arranged on the piston cylinder 25, one end of the medicine supply pipe 22 is connected to the mounting sleeve 2, and the other end is connected to the medicine spraying head 14.

In addition, it can be understood that in some embodiments, a filter can be set on the air inlet check valve 26 to prevent the external air from entering the medicine storage bottle 21 and contaminating the medicine liquid.

[0065] like Figure 3 , 5 As shown in Figures 6 and 7, in this embodiment, a button 3 is provided on the support frame 11 so as to be liftable, and the button 3 is connected to the piston plate 41 through a driving mechanism, and the movement of the button 3 is converted into driving the piston plate 41 to slide through the driving mechanism. The driving mechanism includes a driving rod 32 provided on the button 3, a first elastic member 31 is provided between the driving rod 32 and the mounting groove 15, a driving column 33 is provided at the end of the driving rod 32, a hinged sliding frame 51 is provided on the mounting groove 15, the driving column 33 is slidably provided in the sliding frame 51, a push rod 63 installed through a rocker arm 62 is provided on the sliding frame 51, and a driving arm 42 is hinged at the end of the push rod 63, a piston rod 4 is provided on the piston plate 41, and the other end of the driving arm 42 is hinged to the piston rod 4.

[0066] After being pressed, the button 3 can be reset by the first elastic member 31. During the movement, the button 3 drives the driving rod 32 and the driving column 33 at its end to move. During the movement, the driving column 33 can drive the sliding frame 51 to rotate along the hinge point between it and the mounting groove 15 through the cooperation with the sliding frame 51, so that the rocker arm 62 swings. During the swinging of the rocker arm 62, the piston rod 4 is driven to translate through the cooperation of the push rod 63 and the driving arm 42, so that the piston plate 41 reciprocates in the piston cylinder 25. Each time the button 3 on one side is pressed, a single supply of liquid medicine can be achieved without manually squeezing the medicine bottle, so that the amount of liquid medicine supplied each time is constant.

[0067] like Figure 3 , 5 As shown in FIGS. 6 and 7, in this embodiment, an adjustment mechanism connected to the driving mechanism is provided on the support frame 11, and the sliding distance of the piston plate 41 when the button 3 is pressed once is adjusted by the adjustment mechanism.

When the mounting shaft 6 slides, the position of the rocker arm 62 and the slide frame 51 can be selectively locked or unlocked by the locking assembly. The locking assembly includes a first toothed disc 5 arranged at the end of the slide frame 51 and a second toothed disc 61 arranged on the mounting shaft 6, and the second toothed disc 61 is meshed with the first toothed disc 5. A baffle plate 8 is provided on one side of the mounting groove 15, and a second elastic member 64 is provided between the second toothed disc 61 and the baffle plate 8. A knob 7 is provided at the end of the mounting shaft 6.

[0068] The installation shaft 6 can be driven to slide along its axis by pulling the knob 7. During the sliding process of the installation shaft 6, the second toothed disc 61 is disengaged from the first toothed disc 5, thereby releasing the position lock of the rocker arm 62. Then, the knob 7 is turned to drive the rocker arm 62 to rotate. After the rocker arm 62 rotates to a suitable position, the knob 7 is released, so that the installation shaft 6 is reset under the action of the second elastic member 64, and the second toothed disc 61 is clamped on the first toothed disc 5 again, completing the position lock of the rocker arm 62. The angle between the rocker arm 62 and the slide frame 51 changes, and the horizontal movement distance of the rocker arm 62 will also change when the slide frame 51 rotates the same angle once, so that the movement distance of the piston plate 41 each time the button 3 is pressed can be obtained according to the calculation of trigonometric functions, and a scale line 81 is arranged circumferentially on one side of the baffle 8, and an indicating arrow 74 is provided on the knob 7. The scale line 81 is marked according to the calculation result to accurately adjust the amount of liquid medicine supplied each time the button 3 is pressed. The push rod 63 is slidably disposed at the end of the driving arm 42 along its axis, so that the push rod 63 always maintains an articulated connection with the driving arm 42 during the sliding process of the mounting shaft 6 .

[0069] like Figures 6 to 8As shown, in this embodiment, two groups of relatively slidable push blocks 71 are provided on the knob 7, and the push blocks 71 are connected to the baffle 8 through a propulsion assembly, and the sliding of the push blocks 71 is converted into sliding of the driving mounting shaft 6 through the propulsion assembly. The propulsion assembly includes a third elastic member 73 arranged between the two groups of push blocks 71, and the two groups of push blocks 71 are fixedly provided with push blocks 72, which extend out of one side of the knob 7, and the end of the push blocks 72 is provided with an inclined surface, and one side of the baffle 8 is provided with an annular boss 82, and the inclined surface of the push block 72 can abut against the annular boss 82 after the push block 72 slides.

[0070] When operating the knob 7, the third elastic member 73 can be compressed by pressing the two groups of push blocks 71. The push block 72 follows the movement of the push block 71 during the sliding process. The push block 72 drives the knob 7 to slide along its axis through the contact between its inclined surface and the annular boss 82 during the movement, so that the mounting shaft 6 slides, and then the knob 7 is turned. The locking assembly can be controlled without pulling the knob 7 separately, which improves the convenience of using the device.

[0071] Specific usage and beneficial effects of the present invention:

[0072] When the device is used, it is worn on the head, and the support frame 11 is set on the ear so that the mounting frame 1 is moved to one side of the eye, and the position of the support frame 11 is adjusted so that the spray head 14 is located on the midline of the eyeball, and then the button 3 is pressed. The button 3 drives the piston plate 41 to move through the driving mechanism during the movement. The piston plate 41 supplies the liquid medicine in the medicine storage bottle 21 to the spray head 14 through the medicine supply component during the movement, and sprays it onto the eyeball. In the process of applying the medicine, the eyeball can be instructed to look at the designated position through the indication component to facilitate the local application of medicine to the eye, avoiding the traditional method of dripping medicine so that the diseased position is blocked by the eyelid and the medicine cannot be applied. At the same time, the attention is diverted to avoid the eyes being closed due to stress response during the process of applying the medicine, resulting in waste of liquid medicine. The sliding distance of the piston plate 41 when the button 3 is pressed once can also be adjusted through the adjustment mechanism to adjust the amount of medicine applied to adapt to different patients.
