[0022] When the medicine bottle needs to be replaced, the medical staff controls the lifting transmission assembly 6 to retract upward by pressing the switch button 4. When the lifting transmission assembly 6 retracts to the uppermost end, the clamping relationship between the medicine dropping assembly 8 and the lifting transmission assembly 6 is released, and the storage assembly 7 and the lifting transmission assembly 6 just form a clamping relationship. At this time, the switch button 4 is pressed again to control the motor 5 to drive the lifting transmission assembly 6 and the storage assembly 7 to rotate synchronously. When the medicine dropping assembly 8 rotates to a suitable position, stop pressing the switch button 4, control the motor 5 to stop rotating, and the lifting transmission assembly 6 extends downward. At this time, the storage assembly 7 and the lifting transmission assembly 6 are released, and the medicine dropping assembly 8 and the lifting transmission assembly 6 just form a clamping relationship. Press the switch button 4 again to control the motor 5 to lift and lower the medicine dropping assembly 8. The transmission component 6 drives the medicine dropping component 8 to operate, and the medicine in the medicine dropping component 8 is quantitatively pressed outward.

A plurality of liquid flow holes 14 are also provided on the plate body 11, and the upper end of the liquid flow hole 14 is connected to the circular ring 10, and the lower end of the liquid flow hole 14 is connected to the collection box 40. In the process of switching medicine bottles, dripping medicine and cleaning, residual eye drops and cleaning fluid will be retained in the inner cavity of the circular ring 10, and then enter the collection box 40 through the liquid flow hole 14 for collection, so as to facilitate unified treatment at a later stage.

[0026] The lifting transmission assembly 6 includes a connecting shaft 61 fixedly mounted on the output end of the motor 5 and a driving gear 62 fixedly sleeved on the connecting shaft 61. A driven gear 63 is arranged on one side of the driving gear 62. The driven gear 63 is meshedly connected with the driving gear 62. The driven gear 63 is connected to the motor 5 through a special-shaped lifting rod 64. The driven gear 63 and the special-shaped lifting rod 64 are rotationally connected. The special-shaped lifting rod 64 and the motor 5 are fixedly connected, and the driven gear 63 is coaxially arranged with the through channel 12.

[0027] The connecting shaft 61 includes a mounting shaft 611 fixedly mounted on the output end of the motor 5, and a mounting chamber 612 is provided inside the mounting shaft 611. A lifting shaft 613 is slidably mounted in the inner cavity of the mounting chamber 612. The top surface of the lifting shaft 613 and the top surface of the inner cavity of the mounting chamber 612 are elastically connected by a spring 616. The setting of the spring 616 serves to reset the lifting shaft 613. One end of the special-shaped lifting rod 64 is embedded and rotatably mounted on the side wall of the lifting shaft 613. A plurality of blocks 614 are fixedly mounted on the side wall of the lower end of the lifting shaft 613, and a permanent magnet 615 is fixedly mounted on the bottom surface of the lifting shaft 613.

[0028] The driven gear 63 includes a gear body 631 rotatably mounted on the special-shaped lifting rod 64 , a mounting sleeve 1 632 is fixedly mounted on the bottom surface of the gear body 631 , and a plurality of clamping blocks 2 633 are fixedly mounted on the inner wall of the inner cavity of the mounting sleeve 1 632 .

[0029] The storage assembly 7 includes a storage box 71 rotatably mounted on the mounting column 13 and a dosing port 72 connected and fixedly mounted on the top surface of the storage box 71. The dosing port 72 is used to add eye drops to the interior of the storage box 71. A mounting sleeve 2 73 is fixedly mounted on the top surface of the storage box 71. A plurality of clamping blocks 3 74 are fixedly mounted on the inner wall of the inner cavity of the mounting sleeve 2 73. A clamping relationship can be formed between the clamping block 1 614 and the clamping block 3 74. An electromagnet 75 is fixedly mounted on the bottom surface of the inner cavity of the mounting sleeve 2 73. The electromagnet 75 is aligned with the permanent magnet 615.

[0030] The medicine dropping assembly 8 includes a graduated cylinder 81 fixedly mounted on the side wall of the storage box 71 and a piston plate 82 embedded and vertically slidably mounted in the inner cavity of the graduated cylinder 81. A threaded rod 83 is rotatably mounted in the inner cavity of the graduated cylinder 81. The threaded rod 83 is threadedly connected to the piston plate 82. The bottom of the graduated cylinder 81 is connected to a telescopic liquid outlet assembly 84 fixedly mounted thereon. When the telescopic liquid outlet assembly 84 is not compressed, it is in a closed state to prevent the eye drops in the graduated cylinder 81 from dripping and causing waste. When the telescopic liquid outlet assembly 84 is compressed, it is in a passage state. At this time, the eye drops in the graduated cylinder 81 can flow out of the telescopic liquid outlet assembly 84 after being squeezed by the piston plate 82.

[0031] The threaded rod 83 includes a rod body 831, and a plurality of clamping blocks 832 are fixedly installed on the side wall of the upper end of the rod body 831, and a clamping relationship can be formed between the clamping block 832 and the clamping block 633.

[0032] The telescopic liquid outlet component 84 includes a connecting tube 841 fixedly installed thereon, a sealing ring 842 fixedly installed on the inner wall of the inner cavity of the connecting tube 841, a liquid outlet head 843 also slidably installed on the inner wall of the inner cavity of the connecting tube 841, the liquid outlet head 843 and the sealing ring 842 are elastically connected by a spring 844, and a plurality of liquid inlet holes 845 are opened on the side wall of the liquid outlet head 843.

[0033] Specifically, when the medicine bottle needs to be replaced, the medical staff energizes the electromagnet 75 by pressing the switch button 4, so that the magnetism of the electromagnet 75 is opposite to that of the permanent magnet 615. Under the action of the repulsive force, the lifting shaft 613 drives the driving gear 62 to retract toward the inner cavity direction of the installation chamber 612. At the same time, the lifting shaft 613 also drives the driven gear 63 to move synchronously with the driving gear 62 toward the inner cavity direction of the installation chamber 612 through the special-shaped lifting rod 64. When the lifting shaft 613 is retracted to the uppermost end, the installation sleeve 632 will be withdrawn from the upper end of the rod body 831. The clamping relationship between the second clamping block 633 and the fourth clamping block 832 is released, and the clamping block 1 614 at the lower end of the lifting shaft 613 is inserted in the gap of the third clamping block 74, so that the clamping relationship between the first clamping block 614 and the third clamping block 74 is formed. At this time, the switch button 4 is pressed again, and the control motor 5 drives the connecting shaft 61 and the driving gear 62 to drive the storage assembly 7 to rotate synchronously as a whole. When the scale cylinder 81 rotates to a suitable position, stop pressing the switch button 4, and the control motor 5 stops rotating, and the replacement of the medicine bottle can be completed.

[0034] When it is necessary to add eye drops in a quantitative manner, the electromagnet 75 is powered off, and under the elastic force of the spring 1 616, the lifting shaft 613 extends downward. At this time, the block 1 614 at the lower end of the lifting shaft 613 will be pulled out from the gap of the block 3 74, so that the clamping relationship between the block 1 614 and the block 3 74 is released, and the installation sleeve 1 632 will be sleeved on the upper end, and the block 2 633 will be inserted in the gap of the block 4 832, so that the block 2 633 and the block 4 832 just form a clamping relationship, and the push switch button 4 is pressed again. The control motor 5 drives the threaded rod 83 to rotate in the inner cavity of the scale cylinder 81 through the connecting shaft 61 active gear 62 and the driven gear 63. During the rotation of the threaded rod 83, under the action of the thread, the piston plate 82 slides downward to pressurize the eye drops in the scale cylinder 81.

[0035] When the graduated cylinder 81 is rotated to a suitable position, the telescopic liquid outlet assembly 84 is at the top of the top block 20. At this time, the liquid outlet head 843 is retracted toward the inner cavity of the connecting tube 841. At the same time, the position of the liquid inlet hole 845 is higher than the position of the sealing ring 842. The sealing ring 842 loses its blocking effect on the liquid inlet hole 845. The pressurized eye drops will enter the inner cavity of the liquid outlet head 843 through the liquid inlet hole 845, and then flow from the lower end of the liquid outlet head 843 through the top block 20, the ring 10, and the mounting plate 1. And the dropper 30, and finally drip into the patient's eyes from the lower end of the dropper 30. When the medicine bottle is switched again, the above operation can be repeated. In the process of switching the medicine bottle, the telescopic liquid outlet assembly 84 leaves the top block 20, and under the elastic force of the spring 844, the liquid outlet head 843 pops up downward. At this time, the liquid inlet hole 845 is lower than the highest point of the sealing ring 842, and the sealing ring 842 resumes the blocking effect on the liquid inlet hole 845 to prevent the eye drops from leaking during the process of switching the medicine bottle, resulting in waste of eye drops.

[0036] Through the above-mentioned arrangement, medical staff only need to carry one medicine dropper to complete the eye drop operation for different patients, and can switch between different medicine bottles freely, without the need for medical staff to find medicine bottles one by one and then replace them, thus reducing the frequency of contact between medical staff and medicine bottles, and having high practicality and convenience. In addition, it also reduces the risk of eye drops being contaminated and the risk of cross-infection among patients, and on the premise of switching medicine bottles, quantitative dripping of eye drops can also be achieved.

[0037] In order to solve the technical problem that the traditional portable medicine drop device needs to be disinfected by medical staff after use, if there are a large number of medicine drop devices and they are used frequently, it will increase the workload of medical staff.

A hollow rod 92 is fixedly installed on the outer wall of the electronic liquid outlet valve 91, and a pipe 93 is fixedly installed on the bottom surface of the hollow rod 92 away from the end of the electronic liquid outlet valve 91. A telescopic cleaning head 94 is fixedly installed at the lower end of the pipe 93. The composition structure and connection method of the telescopic cleaning head 94 are consistent with those of the telescopic liquid outlet component 84. An electronic gas valve 2 95 is also fixedly installed on the side wall of the storage box 71, and the electronic gas valve 2 95 is connected to the L-shaped air duct 730, and the electronic gas valve 2 95 is connected to the hollow rod 92 through an air pipe 96.

[0040] The ring 10 includes a ring body 101 fixedly mounted on the top surface of the plate body 11 . A plurality of through holes 102 are provided in the inner cavity of the ring body 101 . The through holes 102 , the plate body 11 and the collection box 40 are connected.

[0041] Specifically, in the process of switching medicine bottles, under the power output of the motor 5, when the storage box 71 rotates, the compression column 77 will slide out of the inner cavity of the arc groove 133 under the action of force, and retract into the inner cavity of the compression chamber 76, compressing the gas in the inner cavity of the compression chamber 76, and the compressed gas will enter the chamber at the upper part of the storage box 71 through the electronic gas valve 79, pressurizing the cleaning liquid stored therein. When the telescopic cleaning head 94 rotates to the upper part of the top block 20, the motor 5 stops rotating, and first opens the electronic liquid outlet valve 91. The cleaning liquid in the upper chamber of the storage box 71, under the action of pressure, will pass through the electronic liquid outlet valve 91, the hollow rod 92, the pipe 93 and the telescopic cleaning head 94 in sequence, and finally flow from the lower end of the telescopic cleaning head 94 through the top block 20, the circular ring 10, the mounting plate 1 and the drip tube 30, pressurizing the top block 20, the circular ring 10, the mounting plate 1 and the drip tube 30. The inside of the ring 10, the mounting plate 1 and the dropper 30 are cleaned to prevent the eye drops from mixing and causing damage to the patient's eyes when the eye drops are replaced. Then the electronic liquid outlet valve 91 is closed and the electronic gas valve 2 95 is opened. Part of the compressed gas in the compression chamber 76 will be blown into the inside of the pipe 93 and the telescopic cleaning head 94 through the electronic gas valve 2 95 and the air pipe 96, and the residual cleaning liquid on the inner wall of the pipe 93 and the telescopic cleaning head 94 will be blown away. The pipe 93, the telescopic cleaning head 94, the top block 20, the ring 10, the mounting plate 1 and the dropper 30 are made of materials with low adsorption properties on the inner walls of the top block 20, the ring 10, the mounting plate 1 and the dropper 30. After being purged with high-pressure gas, there will be almost no residual cleaning liquid. Through such an arrangement, it is prevented that the eye drops and the cleaning liquid are mixed and dripped into the patient's eyes when the medicine is dripped next time, causing personal injury to the patient.

[0042] When the cleaning is completed, the motor 5 is controlled to rotate and the medicine dripping component 8 is rotated to a suitable position for dripping medicine. When the medicine dripping component 8 is rotated to a suitable position, under the elastic force of the spring three 78, the compression column 77 extends toward the outside of the compression chamber 76 and is stuck in the inner cavity of the arc groove 133, thereby achieving the positioning effect of the medicine dripping component 8, which is conducive to the smooth completion of the dripping operation. In the process of the compression column 77 extending toward the outside of the compression chamber 76, the external gas will be sucked into the interior of the compression chamber 76 through the one-way air inlet valve 720 for preparation for the next compression. Through the above-mentioned settings, a continuous disinfection and cleaning effect can be achieved.
