DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to solve the technical problem that during disassembly and replacement, since the original medicine bottle is connected to the medicine dispensing device, the medicine is easily leaked during the disassembly process, resulting in a waste of medicine liquid, such as Figure 1 - Figure 4 As shown, the following preferred technical solutions are provided: An ophthalmic medicine dispensing device comprises a bracket 1 and a slide rail 8. The bracket 1 slides on the slide rail 8, so as to facilitate the adjustment of the distance between the medicine dispensing device and the patient's eye. A table 2 is fixedly connected to the top surface of the bracket 1. A switching dial 4 is rotatably connected to the top surface of the table 2. A plurality of medicine storage components 3 are fixedly installed through the switching dial 4. The plurality of medicine storage components 3 are arranged in a circular array. A quantitative component 5 is fixedly connected to the side wall of the table 2. By rotating the switching dial 4, the medicine storage components 3 containing different medicine solutions can be rotated to the top of the quantitative component 5 and connected thereto. A mounting plate 6 is fixedly connected between the side wall of the bracket 1 and the bottom wall of the table 2. The mounting plate 6 is tilted. A medicine dispensing component 7 is slidably embedded in the mounting plate 6. By tilting the mounting plate 6, the extending direction of the medicine dispensing component 7 is perpendicular to the patient's face, so as to facilitate the position calibration operation between the patient's eye and the medicine dispensing component 7.

[0023] The bracket 1 is integrally in a U-shaped structure. After the patient who needs eye medication lies on the examination chair, the upper body and the head are in an inclined state, so that the face is tilted upwards, which is convenient for medication. Then, the device is pushed along the slide rail 8 close to the patient's face. After the patient's face enters through the opening of the U-shaped bracket 1, the patient's eyes are aligned with the medication component 7 for medication. When medicating, the protective measures set on the medication component 7 can prevent the patient's eyes from colliding with the medication nozzle when the patient is hit, thus protecting the patient's eyes. By setting the switching turntable 4, when different medicaments are needed for medication, the user can rotate the switching turntable 4 to drive multiple medicine storage components 3 to rotate, and finally rotate the required medicine storage component 3 above the metering component 5 and communicate with it.

[0024] By setting the metering component 5, the amount of the medicament dropped can be more accurately controlled each time when medicating, avoiding the problem that the treatment effect cannot be achieved when too little is dropped, or the medicament overflows from the eyes and causes waste when too much is dropped. When another medicament is needed, first flush the inside of the metering component 5 to avoid cross-contamination of the medicaments, and disinfect the inside of the metering component 5 after use.

[0025] The medicine storage component 3 includes a medicine storage bottle 31 fixedly installed through the switching turntable 4. The medicine storage bottle 31 is in a cylindrical bottle body structure. A through hole 311 is opened on the bottom surface of the medicine storage bottle 31. A plurality of first elastic mechanisms 32 are fixedly connected to the lower end of the inner cavity side wall of the medicine storage bottle 31. The plurality of first elastic mechanisms 32 are arranged in a circular array. The movable ends of the plurality of first elastic mechanisms 32 are fixedly connected to a sealing plate 33 together.

[0026] A first threaded rod 34 is threadedly connected through the top surface of the medicine storage bottle 31. One end of the first threaded rod 34 located inside the medicine storage bottle 31 is fixedly connected to a limiting block 35. A filling pipe 36 is fixedly connected through the side wall of the medicine storage bottle 31.

[0027] The first elastic mechanism 32 includes a fixed seat 321 fixedly connected to the lower end of the inner cavity side wall of the medicine storage bottle 31. A groove 322 is opened at the bottom end of the fixed seat 321. A slide rod 323 is slidably connected inside the groove 322. The bottom end of the slide rod 323 is fixedly connected to the top surface of the sealing plate 33. The top end of the slide rod 323 is elastically connected to the top wall of the inner cavity of the groove 322 through a spring 324.

[0028] Specifically, during use, when it is necessary to replace the medicine storage bottle 31 connected to the device, the currently connected medicine storage bottle 31 is turned away by rotating the switching dial 4. During this process, the first elastic mechanism 32 pushes the slide bar 323 out of the groove 322 through the elastic force of the spring 324. Under the joint push of multiple slide bars 323, the sealing plate 33 and the through hole 311 provided on the bottom surface of the medicine storage bottle 31 are tightly abutted, thereby sealing the medicine storage bottle 31 to avoid leakage during the transfer process and waste of medicine. At the same time, the first threaded rod 34 can be rotated to drive the limit block 35 to descend inside the medicine storage bottle 31, and finally the sealing plate 33 is locked from the inside. At this time, the sealing plate 33 cannot be pushed inward from the outside, which further strengthens the sealing of the medicine storage bottle 31 during the transfer process and effectively reduces accidental leakage.

[0029] In order to solve the inconvenient technical problem that only one medicine storage device can be installed in the existing device, and it needs to be disassembled and replaced when dealing with different situations, such as Figure 3 - Figure 8 As shown, the following preferred technical solutions are provided: The quantitative component 5 includes a quantitative cylinder 51 fixedly connected to the side wall of the table 2, a transparent plate 511 is fixedly connected through the side wall of the quantitative cylinder 51, and the transparent plate 511 is provided with scale values, a connecting mechanism 52 is fixedly installed on the side wall of the top of the inner cavity of the quantitative cylinder 51, a partition plate 53 is fixedly connected to the side wall of the inner cavity of the quantitative cylinder 51, and the partition plate 53 is arranged as a whole at the bottom of the connecting mechanism 52.

[0030] The connecting mechanism 52 includes a plurality of second elastic mechanisms 521 fixedly connected to the top end of the inner cavity side wall of the quantitative cylinder 51. The structure of the second elastic mechanism 521 is the same as that of the first elastic mechanism 32. The installation direction of the second elastic mechanism 521 is opposite to that of the first elastic mechanism 32. The movable ends of the plurality of second elastic mechanisms 521 are commonly fixedly connected to a connecting plate 522. The side wall of the connecting plate 522 slides against the inner cavity side wall of the quantitative cylinder 51. A top ball 523 is fixedly connected through the center of the top surface of the connecting plate 522. The top ball 523 has a hollow structure inside. A plurality of connecting holes 5231 are provided on the outer wall of the upper hemisphere of the top ball 523. A first one-way tube 5232 is fixedly connected through the outer wall of the lower hemisphere of the top ball 523. The first one-way tube 5232 is slidably arranged with the partition plate 53. The first one-way tube 5232 only allows the medicine to enter the quantitative cylinder 51 from the medicine storage bottle 31.

[0031] A second threaded rod 54 is threadedly connected to the bottom surface of the metering cylinder 51, and a piston 55 is fixedly connected to one end of the second threaded rod 54 located inside the metering cylinder 51. The side wall of the piston 55 slides against the side wall of the inner cavity of the metering cylinder 51, and a second one-way tube 56 is fixedly connected to the outer wall of the side where the metering cylinder 51 is connected to the table 2.

[0032] Specifically, when different medicine solutions are needed for treatment, the corresponding medicine storage component 3 is rotated to the top of the quantitative component 5 by switching the turntable 4, and the first threaded rod 34 is loosened. During this process, the top ball 523 slides against the bottom surface of the medicine storage bottle 31, and the second elastic mechanism 521 is compressed after being squeezed. When it is aligned with the through hole 311 opened on the bottom surface of the medicine storage bottle 31, the second elastic mechanism 521 releases its elastic force to clamp the top ball 523 therein, and lift up the sealing plate 33, thereby opening the medicine storage bottle 31. At the same time, since the top ball 523 is a hollow structure inside, and A plurality of connecting holes 5231 are provided on the outer wall of the upper hemisphere, and a first one-way tube 5232 is fixedly connected to the outer wall of the lower hemisphere, so that a passage is formed between the medicine storage bottle 31 and the inside of the metering cylinder 51. Due to the arrangement of the second threaded rod 54 and the piston 55, the amount of medicine entering can be controlled by moving the piston 55 and observing the scale value on the transparent plate 511. Thus, the switching connection of different medicine storage bottles 31 is realized through the above structure, which is convenient for use. At the same time, the medicine can be quantified. When the piston 55 is compressed in the reverse direction, a quantitative amount of medicine is squeezed out for applying the medicine.

[0033] In order to solve the technical problem that in the process of applying medicine to the patient, the outlet of the medicine applying device is thin and close to the patient's eyes, when the patient is hit during the process of applying medicine, the medicine applying device is easy to cause damage to the patient's eyes, such as Fig. 9 - Fig.10 As shown, the following preferred technical solutions are provided: One end of the second one-way tube 56 is connected to the interior of the metering cylinder 51 and is arranged at the end of the compression stroke of the piston 55. The other end of the second one-way tube 56 is fixedly connected to a three-way tube 57. A flushing tube 58 and a disinfection tube 59 are fixedly connected to the outer wall of the metering cylinder 51.

[0034] A strip-shaped hole 61 is formed on the side wall of the mounting plate 6 .

[0035] The medicine dispensing component 7 includes a bidirectional screw rod 71 which is rotatably connected to the inside of the strip hole 61, and a moving block 72 is symmetrically threaded on the side wall of the bidirectional screw rod 71. A dropper head 73 and a positioning protective cover 74 are fixedly connected to the side wall of each moving block 72. The positioning protective cover 74 is made of elastic material and has a trumpet-shaped structure. Each dropper head 73 is arranged inside the corresponding positioning protective cover 74, and the two ends of the three-way pipe 57 away from the second one-way pipe 56 are respectively connected to the two dropper heads 73.

[0036] Specifically, the second one-way tube 56 only allows the medicine to enter the three-way tube 57 from the metering cylinder 51, and the squeezed medicine enters the interior of the dropper head 73 through the second one-way tube 56. When applying the medicine, the distance between the two dropper heads 73 can be fine-tuned by rotating the two-way screw rod 71, so as to adapt to the eye distance of different patients and achieve a more accurate medicine application effect. By setting the positioning protective cover 74, it is convenient to align the position of the patient's eyes with the dropper head 73. At the same time, when the patient is hit during the medicine application process, it can also prevent his eyes from touching the dropper head 73 to avoid damage to the patient's eyes.
