The embodiment of the invention discloses an eye drop device which is suitable for a cylindrical eye medicine bottle packaged by plastic and comprises a fixing frame 1, a spreading component 2 and a pressing plate component 3.
The fixing frame 1 is used for fixing the bottle body 01 on one hand and providing support for the installation of other components on the other hand.
The opening component 2 is hinged to the bottom of the fixing frame 1, so that the opening component 2 is positioned right below the bottle mouth. The opening component 2 is hinged with the fixed frame 1 through a pin shaft, so that the opening component 2 rotates around the pin shaft relative to the fixed frame 1. When the opening assembly 2 is opened, the upper eyelid and the lower eyelid are opened by the opening assembly 2. The opening assembly 2 can be closed by means of magnets of different polarities, the closing manner of which is described below.
The pressing plate assembly 3 extends along the length direction of the bottle body 01, the first end of the pressing plate assembly 3 is hinged to the top of the fixing frame 1, and the second end of the pressing plate assembly is elastically propped against the opening assembly 2. When the pressing plate assembly 3 is pushed, the first end of the pressing plate assembly 3 rotates relative to the fixing frame 1, so that the second end of the pressing plate assembly 3 overcomes the elastic force to apply torque to the expanding assembly 2, and the expanding assembly 2 is pushed to rotate relative to the fixing frame 1, so that the expanding assembly 2 is expanded. When the pressing plate assembly 3 is released, the second end of the pressing plate assembly 3 is reset by means of elastic force, the torque applied to the opening assembly 2 disappears, and the opening assembly 2 is reset until the opening assembly 2 is closed by means of magnetic attraction force.
The pressure plate assembly 3 is provided with an adjusting screw 4, and the adjusting screw 4 is perpendicular to the pressure plate assembly 3, so that the adjusting screw 4 is close to or far away from the bottle body 01. It should be noted that, before the pressing plate assembly 3 pushes the opening assembly 2 to open, the adjusting screw 4 needs to be adjusted according to a preset dosage, so that a preset distance between the adjusting screw 4 and the bottle body 01 is kept, and the bottle body 01 is prevented from being extruded in advance by the adjusting screw 4 in the process that the pressing plate assembly 3 pushes the opening assembly 2 to open, so that eye drops are prevented from being dropped before eyelid is opened. After the eyelid is propped open by the propping open assembly 2, the adjusting screw 4 is rotated again, so that the adjusting screw 4 is propped against the bottle body 01, and preparation is made for the adjusting screw 4 to extrude the bottle body 01. The correspondence between the preset dosage and the preset distance can be preset according to the dosage and experience.
The pressing plate assembly 3 comprises two pressing plates 31 which are oppositely arranged, and the two pressing plates 31 are parallel to the central line of the bottle body 01. Each pressing plate 31 is vertically provided with an adjusting screw 4, and the adjusting screw 4 is in threaded fit with a threaded hole formed in the pressing plate 31, so that the adjusting screw 4 extrudes along the radial direction of the bottle body 01 or is far away from the bottle body 01.
Considering that the bottle body 01 is cylindrical, the end of each adjusting screw 4 is provided with an arc-shaped top sheet 7. Each arc-shaped top piece 7 is fixed with an anti-rotation guide rod 71, each pressing plate 31 is provided with an anti-rotation guide groove 311, and the anti-rotation guide rods 71 are matched with the anti-rotation guide grooves 311, so that the anti-rotation guide grooves 311 guide the anti-rotation guide rods 71 to move only along the axial direction of the bottle body 01, and then the arc-shaped top pieces 7 move only along the axial direction of the bottle body 01, and are used for limiting the rotation of the arc-shaped top pieces 7 along with the adjusting screw 4, so that the positions of the arc-shaped top pieces 7 are kept unchanged, and the arc-shaped top pieces 7 are prevented from being skewed. Specifically, each arc-shaped top piece 7 is integrally provided with a connecting sleeve matched with the adjusting screw 4, the connecting sleeve extends along the radial direction of the bottle body 01, and the anti-rotation guide rods 71 are integrally arranged on the connecting sleeve, so that the anti-rotation guide rods 71 are bent from the connecting sleeve positions to the anti-rotation guide grooves 311. The anti-rotation guide bar 71 is specifically an L-shaped bar. The rotation preventing groove 311 is a waist-shaped groove extending in the axial direction of the bottle body 01, and penetrates in the thickness direction of the pressing plate 31.
When in use, firstly, the bottle body 01 of the eye medicine bottle is inversely placed into the fixing frame 1, and the bottle body 01 is fixed by the fixing frame 1; the adjusting screw 4 is rotated by the preset dosage, so that the adjusting screw 4 keeps a preset distance from the bottle body 01; then the hand-held fixing frame 1 is moved towards the eyes until the bottle mouth is aligned with the eyes; then the pressing plate component 3 is initially pressed, the adjusting screw 4 leans against the bottle body 01 along with the pressing plate component 3 until the adjusting screw 4 is propped against the bottle body 01, meanwhile, the pressing plate component 3 overcomes the elastic force to push the propping component 2 to prop open the eyelid until the propping component 2 is propped against the fixing frame 1, at the moment, the propping component 2 is limited, and the eyelid is fully propped open; finally, the pressing plate assembly 3 is continuously pressed, the opening assembly 2 is still, the eyelid is kept in an opened state, the pressing plate assembly 3 is close to the bottle body 01, the adjusting screw 4 drives the arc-shaped top piece 7 to squeeze the bottle body 01, and eye drops with preset dosage drop into the opened eyes, so that the dropping quantity of the eye drops is accurately controlled.
The fixing frame 1 comprises a limiting ring 11, when the bottle body 01 is inversely installed in the fixing frame 1, the bottle mouth is propped against the limiting ring 11, and the position of the bottle body 01 is limited by the limiting ring 11. The stop collar 11 may be, but not limited to, a ring.
The spreader assembly 2 includes a first strut 21 and a second strut 22, the first strut 21 and the second strut 22 being oppositely hinged to opposite sides of the stop collar 11. Specifically, the two opposite sides of the limiting ring 11 are integrally provided with a U-shaped hinge groove, and the first support rod 21 and the second support rod 22 are hinged in the U-shaped hinge groove by virtue of pin shafts.
The bottom of each U-shaped hinge groove is provided with a limiting inclined plane 111, and the opening angles of the first supporting rod 21 and the second supporting rod 22 are respectively limited by the limiting inclined planes 111, so that two actions of opening eyelid and dripping eyedrops can be simultaneously completed by one-time pressing. Before the pressing plate assembly 3 pushes the opening assembly 2 to open, the proper distance between the adjusting screw 4 and the bottle body 01 can be set according to practical situations, but the distance needs to be set to ensure that the arc-shaped top piece 7 of the adjusting screw 4 just abuts against the outer contour of the bottle body 01 when the first supporting rod 21 or the second supporting rod 22 abuts against the limiting inclined surface 111.
The push rod 5 is arranged at the bottom of each pressing plate 31 of the pressing plate assembly 3 in a penetrating manner, the opening assembly 2 is provided with an opening guide groove 20, the push rod 5 is transversely inserted into the opening guide groove 20, the push rod 5 is sleeved with the pushing elastic piece 6, and the pushing elastic piece 6 abuts against the pressing plates 31. When the pressing plate assembly 3 is pressed, the push rod 5 overcomes the elastic force of the pushing elastic piece 6 under the pushing of the pressing plate assembly 3, and pushes the opening assembly 2 to rotate around the fixing frame 1 along the opening guide groove 20. It should be noted that, when the pressing plate assembly 3 is pressed for the first time, the pushing elastic member 6 is not fully compressed, and only the pushing assembly 2 is required to slightly push the eyelid under the action of the pushing rod 5. When the pressing plate is pressed for the second time, the compression amount of the pushing elastic piece 6 reaches the maximum, so that the opening assembly 2 can be ensured to fully open the eyelid under the action of the pushing rod 5.
Specifically, each pressing plate 31 respectively abuts against the first supporting rod 21 and the second supporting rod 22 through one pushing rod 5, when the two pressing plates 31 are pressed simultaneously, when the pressing force exerted by the pressing plates 31 is large, the two pressing plates 31 respectively push the first supporting rod 21 and the second supporting rod 22 to synchronously rotate around the respective pin shafts relative to the limiting ring 11 through one pushing rod 5, and the first supporting rod 21 and the second supporting rod 22 are synchronously opened or closed by means of the lever principle. The opening guide groove 20 is respectively disposed at the top ends of the first supporting rod 21 and the second supporting rod 22, and the opening guide groove 20 is specifically a strip-shaped groove with one end open and extending along the axial direction of the bottle body 01. During the rotation of the first stay bar 21 and the second stay bar 22, each push rod 5 is pressed to the expanding guide groove 20 along the depth direction of the expanding guide groove 20, and moves along the length direction of the inserted expanding guide groove 20, and the movement track of the push rod 5 is a sector track moving along the radial direction of the bottle body 01.
One end of each adjusting screw 4, which is far away from the bottle body 01, is fixedly provided with a rotary disk 41, so that a patient can conveniently rotate the adjusting screw 4 through the rotary disk 41. One end of the adjusting screw 4, which is far away from the rotary disc 41, is integrally provided with a spherical bulge 42, and the connecting sleeve of each arc-shaped top piece 7 is matched with the spherical bulge 42 to form universal head connection. Each pressing plate 31 is integrally and fixedly provided with a pressing plate, and the center of the pressing plate is provided with a groove, so that the pressing plate is convenient for fingers to press.
One end of each push rod 5 close to the expanding guide groove 20 is uniformly and fixedly provided with an abutting ring, and two ends of the pushing elastic piece 6 respectively abut against the pressing plate 31 and the abutting ring, so that the push rods 5 are ensured to push the first supporting rod 21 and the second supporting rod 22 to rotate along the expanding guide groove 20 when the pushing force exerted by the pressing plate 31 is overlarge. The urging elastic member 6 may be, in particular, a normal cylindrical spring, but is not limited thereto.
The first stay bar 21 and the second stay bar 22 are both bending bars, and specifically gather from the periphery of the limiting ring 11 along the radial direction of the bottle body 01 to the central line of the bottle mouth, and are symmetrically arranged. A set of first magnetic blocks 211 and second magnetic blocks 221 with different polarities are arranged between the first supporting rod 21 and the second supporting rod 22. The first magnetic block 211 and the second magnetic block 221 are oppositely arranged, and are respectively arranged on the corresponding surfaces of the first supporting rod 21 and the second supporting rod 22. When the pressing plate assembly 3 is not pressed, the first magnetic block 211 and the second magnetic block 221 are attracted by virtue of magnetic attraction, so that the two are ensured to open eyelid in a closed state. Obviously, the arrangement of the first magnetic block 211 and the second magnetic block 221 can ensure that the first magnetic block 211 and the second magnetic block 221 fully prop open eyelid in a closed state, and can prevent the first supporting rod 21 and the second supporting rod 22 from interfering with the bottle body 01 to be arranged in the fixing frame 1.
The first supporting rod 21 and the second supporting rod 22 are respectively provided with an outwards protruding arc supporting rod, namely, the bottom end of the first supporting rod 21 is integrally and vertically provided with a first arc supporting rod 212, and the bottom end of the second supporting rod 22 is integrally and vertically provided with a second arc supporting rod 222.
Each arc stay bar comprises a transition plane 2121, and an inner arc face 2122 and an outer arc face 2123 which are symmetrically arranged on two sides of the transition plane 2121 respectively, namely, the two arc stay bars adopt a double-arc structure, and the bending radians of the inner arc face 2122 and the outer arc face 2123 are the same.
