Description

Technical Field

[0001] The utility model relates to the technical field of eye drop mixing, and more specifically, to an eye drop mixing mechanism. Background Art

[0002] Eye drops are the most widely used ophthalmic preparation in clinical practice. Topical application typically provides antiseptic, anti-inflammatory, mydriatic, miotic, and anesthetic effects. Eye drops are a key therapeutic approach, well-accepted by patients and widely used. To prevent excessive irritation and stabilize the drug, buffer solutions are often used to stabilize the pH of the solution. To this end, a mixing mechanism has been proposed for mixing eye drops to stabilize the pH of the solution.

[0003] After searching, for example, the Chinese patent application with publication number CN219964741U discloses a mixing mechanism for preparing moxifloxacin hydrochloride eye drops. The mechanism achieves rotational mixing of the eye drops by intermittent reverse rotation of a gear transmission structure. This solves the problem that in the existing eye drop mixing device, a rotating mixing rod is set in a mixing box to mix the raw materials of the eye drops to ensure the mixing effect during the preparation and mixing of the eye drops. Although this method has high mixing efficiency, the mixing device is an integrated fixed connection mechanism, and the mixing rod and mixing box cannot be disassembled for disinfection and cleaning. Over time, the mixing device is contaminated by bacteria, which will affect the final mixing quality of the moxifloxacin hydrochloride eye drops. The problem is that by setting a clamping and fixing mechanism of the mixing box and an eye drop mixing box body, the integrated connection mode of the mixing equipment is changed, the clamping and disassembly of the eye drop mixing box is realized, and the eye drop mixing box body can be disassembled and disinfected at will, which solves the problem that in the existing eye drop mixing device, when preparing and mixing eye drops, a rotating mixing rod is set in the mixing box to mix the raw materials of the eye drops to ensure the mixing effect. Although this method has high mixing efficiency, since the mixing device is an integrated fixed connection mechanism, the mixing rod and mixing box cannot be disassembled for disinfection and cleaning. Over time, the mixing device is contaminated with bacteria, which will affect the final mixing quality of moxifloxacin hydrochloride eye drops.

[0004] However, when the above solution is used, the eye drop mixing box is rotated back and forth laterally to mix the eye drops. Due to the inertia of the liquid, the eye drops will rotate and gather in the eye drop mixing box, resulting in the eye drops not being completely dispersed in the liquid, thereby affecting the mixing efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an eye drop mixing mechanism, and the technical problem to be solved is that the efficiency of mixing eye drops by horizontal reciprocating rotation is low.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an eye drop mixing mechanism, comprising a box body:

[0007] The upper end of the box body is provided with a placement groove, and an eye drop mixing box is movably provided inside the placement groove;

[0012] In a preferred embodiment, a rotating armrest is fixedly provided on one side of the screw sleeve, a movable connecting seat is movably provided on one end of the screw, and a protrusion on one end of the screw is adapted to an inner groove of the movable connecting seat.

[0013] In a preferred embodiment, an arc-shaped clamping plate is fixedly provided on one side of the movable connecting seat, and an anti-slip pad is fixedly provided on one side of the arc-shaped clamping plate.

[0014] In a preferred embodiment, a semicircular gear is fixedly provided on the outer surface of the movable connection seat, and the semicircular gear is meshedly connected with the toothed plate.

[0025] 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 embodiments described 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 the field of eye drop mixing without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 and 2 As shown, the utility model provides an eye drop mixing mechanism, including a box body 1: a placement groove 4 is opened on the upper end of the box body 1, an eye drop mixing box 5 is movably provided inside the placement groove 4, and a controller 6 is fixedly provided on one side of the box body 1.

[0027] In order to be able to clamp the eye drop mixing box 5 for installation and fixation, thereby reducing the use of motors and reducing the cost, a clamping and fixing device 2 capable of clamping the eye drop mixing box 5 is provided on both sides of the box body 1 for clamping the eye drop mixing box 5 for installation and fixation;

[0028] like Figure 3 As shown, the clamping and fixing device 2 includes a screw sleeve 22, which passes through the through groove on one side of the box body 1. The screw sleeve 22 is movably connected to the through groove on one side of the box body 1. The inner side of the screw sleeve 22 is threadedly connected to a screw rod 21. A rotating armrest 23 is fixedly provided on one side of the screw sleeve 22. A movable connecting seat 24 is movably provided at one end of the screw rod 21. A protrusion at one end of the screw rod 21 is adapted to the groove on the inner side of the movable connecting seat 24. An arc-shaped splint 7 is fixed on one side of the movable connecting seat 24. An anti-slip pad 8 is fixed on one side of the arc-shaped splint 7, which passes through the screw sleeve 22 on both sides. The screw rod 21 and the rotating armrest 23 can push the screw rod 21, and utilize the engagement of the semicircular gear 37 and the toothed plate 32 to limit the movable connecting seat 24 and the arc-shaped splint 7. When the eye drop mixing box 5 needs to be fixed, the rotating armrests 23 on both sides are rotated to move the two arc-shaped splints 7 toward the center, which can clamp the eye drop mixing box 5 for installation and fixation, thereby reducing the use of motors and reducing manufacturing costs.

[0029] Furthermore, in order to improve the mixing efficiency of the eye drops of the present invention, a shaking mixing device 3 capable of driving the eye drop mixing box 5 to swing is provided on the inner side of the box body 1, and is used to reciprocate the eye drops in the eye drop mixing box 5;

[0030] like Figure 4 As shown, the shaking mixing device 3 includes two C-shaped rods 31, which are fixedly arranged on both sides of the inner wall of the box body 1. The two C-shaped rods 31 are mirror-imaged with the center of the box body 1 as the axis. The two C-shaped rods 31 are movably provided with the same toothed plate 32 on the inner side. The protrusions on both sides of the toothed plate 32 are adapted to the grooves on the inner side of the C-shaped rod 31. A semicircular gear 37 is fixedly provided on the outer surface of the movable connecting seat 24. The semicircular gear 37 is meshed with the toothed plate 32. A hinge seat 33 is fixed on one side of the toothed plate 32. A transmission rod 34 is hinged on the inner side of the hinge seat 33. A rotating motor 35 is fixed on one side of the inner wall of the box body 1 through a bracket. A rotating disk 36 is fixedly provided at the output end of the driving motor 35, and the lower end of one side of the rotating disk 36 is hinged to one end of the transmission rod 34. By rotating the rotating motor 35, the transmission rod 34 and the hinge seat 33 are utilized to pull the toothed plate 32. By rotating the rotating disk 36, the toothed plate 32 is reciprocated on the inner side of the C-shaped rod 31. When the toothed plate 32 reciprocates, it can drive the two semicircular gears 37 to rotate reciprocatingly. Since the semicircular gears 37 are fixed on the outer surface of the movable connecting seat 24, the two arc-shaped splints 7 and the eye drop mixing box 5 are driven to swing back and forth, thereby improving the mixing efficiency of the eye drops of the utility model.

[0031] The working principle is as follows: when the present invention is in use, eye drops and buffer solution are loaded into the eye drop mixing box 5, the eye drop mixing box 5 is clamped between two arc-shaped plywood 7 by the clamping fixing device 2, and the anti-slip pad 8 can prevent the eye drops from being separated from the eye drop mixing box 5 during the mixing process. After the eye drop mixing box 5 is fixed, the eye drops can be mixed by using the shaking mixing device 3, which improves the overall cost of the present invention and improves the efficiency of mixing eye drops of the present invention.

[0032] In addition, it is worth noting that the control process of the rotating motor 35 and other electronic devices in the present invention is implemented by the controller 6, which is powered by an external power supply. The circuit design and structure belong to mature existing technologies, so they will not be further described in the present invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
