It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.
[0037] In the description of the utility model, it is understood that the directions or position relations of the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relations shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model. In addition, in the description of the utility model, the meaning of "a plurality of" is two or more than two, unless otherwise specifically limited.
[0038] Figures 1 to 7 The first embodiment of the utility model is shown: a kind of eye lid expansion support type eye drop fixer, including fixed handle 1 and rotating handle 2, the upper section of the fixed handle 1 is fixedly provided as hand grip part with first handle 3, the middle section of the fixed handle 1 is detachably installed as mounting part with eye drops bottle 4, the lower section of the fixed handle 1 is movably provided as expansion support part with eye lid expansion support structure 5, the eye lid expansion support structure 5 is mechanically linked with the rotating handle 2, and in the rotating process of the rotating handle 2, on the one hand, it can prop open user eye lid, to ensure that user eyeball is fully exposed below the drip opening of eye drops bottle 4, on the other hand, it can squeeze eye drops bottle 4, so that eye drops are dropped into user eyeball from drip opening.
[0039] Please refer to Figure 8 And Figure 9 , when specific implementation, the lower section of the rotating handle 2 is provided as mechanical linkage part with the clamping arm structure 6 being rotationally connected with the fixed handle 1, the upper section of the rotating handle 2 is provided as hand-held pressing part with bottle body extruding structure 7 being rotationally connected with the clamping arm structure 6, the rotation moment of the bottle body extruding structure 7 and the clamping arm structure 6 is different, to ensure that the bottle body extruding structure 7 can continue to rotate to squeeze the bottle body of eye drops bottle 4 after the clamping arm structure 6 drives the eye lid expansion support structure 5 to expand in place. Rotating handle 2 adopts segmented design, the bottle body extruding structure 7 of upper section can rotate with clamping arm structure 6 during eye lid expansion support, and can independently rotate after eye lid expansion support is in place, to fully squeeze the bottle body of eye drops bottle 4, so as to ensure that eye drops drop amount meets the treatment requirement.
[0040] As Figure 3 And Figure 4As shown, in order to synchronously expand the patient's upper and lower eyelids to fully expose the eyeballs, and to achieve the technical effect of automatically resetting the eyelid expansion structure 5 after releasing the rotating handle 2, the clamping arm structure 6 includes two clamping arms 601, which are meshed and driven by a gear assembly 602, and a worm spring 603 is provided between each clamping arm 601 and the fixed handle 1. Specifically, the gear assembly 602 includes two gears connected to the rotating shafts of the two clamping arms 601, and the two gears are meshed. When one clamping arm 601 rotates, the gear on its rotating shaft rotates with it, thereby driving the clamping arm 601 away from or towards each other through the gear on the rotating shaft of the other clamping arm 601.
[0041] In this embodiment, the expansion portion is configured as an L-shaped support structure 101. The eyelid expansion structure 5 includes two eyelid expansion blocks 501 movably connected to the straight section of the support structure 101. Each eyelid expansion block 501 is provided with a guide groove 502, in which a roller 503 is connected. The roller 503 is connected to the end of the corresponding clamping arm 601. Under the action of the guide groove 502 and the roller 503, the rotational motion of the clamping arm 601 is converted into linear motion of the eyelid expansion block 501 within the straight section of the support structure 101. Preferably, to prevent the eyelid expansion blocks 501 from excessively pressuring the user's eye area and to improve comfort and safety, a flexible pad 504 is detachably mounted at the bottom of each eyelid expansion block 501. The flexible pad 504 is configured in an outwardly increasing stepped shape to adapt to the contour of the human eye area.
[0042] like Figures 6 to 9 As shown, in a specific application, the bottle body squeezing structure 7 includes a connecting arm 702 connected to one of the clamping arms 601 via a torsion spring shaft 701. The lower section of the connecting arm 702 is provided with a squeezing roller 703 opposite to the eye drop bottle 4, and the upper section of the connecting arm 702 is connected to a second grip 704. Preferably, to facilitate the installation and replacement of the eye drop bottle 4 and improve the stability of the eye drop bottle 4 after installation, the middle section of the fixed handle 1 adopts a groove-shaped structure 102. The groove body size of the groove-shaped structure 102 is adapted to the bottle body size of the eye drop bottle 4, and its groove is located at a position relative to the rotating handle 2. A through hole 103 is also provided on the lower groove wall of the groove-shaped structure 102 for the dripping port of the eye drop bottle 4 to pass through.
[0043] Next, we will further explore the detailed design and application advantages of this eyelid expansion eye drop holder.
[0044] Firstly, regarding the arrangement of the worm spring 603 in the clamp arm structure 6, the elastic force of the worm spring 603 enables the clamp arm 601 to automatically reset after the rotating handle 2 is released, which greatly improves the convenience of use.
[0045] In the design of the guide groove 502 and the roller 503, we use high-precision machining technology to ensure that the roller 503 can smoothly slide in the guide groove 502, thereby accurately converting the rotary motion of the clamping arm 601 into the linear motion of the eyelid expansion block 501.
[0046] Regarding the design of the flexible pad 504, we use soft medical materials such as silicone to ensure that there is no pressure or discomfort to the patient's eye during the process of expanding the eyelid. At the same time, the stepped design of the flexible pad 504 also makes it better fit the contour of the human eye, improving the comfort and safety of use.
[0047] In the design of the bottle body extrusion structure 7, we use a combination of torsional spring shaft 701 and connecting arm 702, so that after the clamping arm structure 6 drives the eyelid expansion structure 5 to expand to the right place, the bottle body extrusion structure 7 can continue to rotate to extrude the bottle body of the eye drop bottle 4. This design ensures the accuracy and consistency of the eye drop amount, thereby improving the treatment effect.
[0048] In addition, we also use a slot structure 102 in the middle section of the fixed handle 1 to facilitate the installation and replacement of the eye drop bottle 4. At the same time, the slot size of the slot structure 102 is matched with the bottle size of the eye drop bottle 4, and the slot opening is located at the opposite position of the rotating handle 2, which makes the eye drop bottle 4 stable during the eye drop process, not easy to shake, thereby further improving the safety and convenience of use.
[0049] In summary, the utility model discloses through the single operation of rotating handle 2, can realize the dual function of eye lid expansion and eye drop extrusion, greatly simplifies the operation process, reduces the operation difficulty. For the old people, children or the patient of poor hand coordination, this is undoubtedly a great gospel. At the same time, since the operation process is more convenient, also reduces the eye infection risk caused by improper operation;The utility model discloses the innovative mechanical linkage design, not only simplifies the operation process of eye drop, also greatly improves the accuracy and safety of operation. Its unique eye lid expansion structure 5 can ensure that the eyeball of user is fully exposed under the drop opening of eye drop bottle 4, thereby avoiding the problem of inaccurate or insufficient drop of eye drop caused by insufficient exposure of eyeball. At the same time, the differential rotation torque design of bottle body extrusion structure 7 and clamping arm structure 6 ensures that after eye lid expansion is in place, can continue to rotate to the bottle body of extruding eye drop bottle 4, realizes the smooth drop of eye drop;The utility model also considers the comfort of user. The expansion part adopts L-shaped support structure 101, makes the eye lid expansion more stable, reduces the eye discomfort possibly caused by unstable expansion. And the flexible pad 504 of detachable installation of eye lid expansion block 501 bottom, improves the comfort of user, and the stepped design makes the pad better adapt to the eye contour of human body, reduces the compression feeling caused to eye when expanding. At the same time, the design of double eye lid expansion block 501 and double clamping arm 601 makes that user can expand upper and lower eye lids simultaneously when holding rotating handle 2, to ensure that the eyeball of user is fully exposed, makes the accurate drop of eye drop into the eye of user;In the safety aspect, the utility model also makes full consideration. The middle segment of fixed handle 1 adopts groove-shaped structure 102, and the groove size of its groove body is adapted to the bottle size of eye drop bottle 4, not only ensures the stable installation of eye drop bottle 4, but also avoids the problem of inaccurate or excessive drop of eye drop caused by shaking during the pressure process of eye drop bottle 4. At the same time, the through hole 103 of lower groove wall of groove-shaped structure 102 makes that the drop opening of eye drop bottle 4 can be through between two eye lid expansion blocks 501, further guarantees the smooth drop of eye drop.
[0050] Finally, it needs to be explained that the above disclosed technical solutions are only a preferred embodiment of the utility model, and of course cannot limit the scope of the utility model, and the person skilled in the art can understand that the whole or part of the above-mentioned embodiment is realized, and the equivalent changes made according to the utility model claim still belong to the scope covered by the utility model.
